	Ever since you arrived in Equestria as a part of some weird experiment you signed up for since you were broke, you had to learn a lot of stuff in a very short amount of time to try and fit in with the locals. Surprisingly enough, the creatures here, who called themselves “ponies”, were more like humans than the horses you had imagined. They stood on two legs, had arms, hands, opposable thumbs, the whole deal. Their heads had muzzles instead of the traditional nose, and the ears were like horse ears, and on top of their head. They had tails, and some had horns, some had wings, and a few happened to have both. That’s the brief lesson you were given when you got to Equestria and into this castle, where a particular purple pony greeted you. She said her name was Twilight Sparkle, and she was the “Element of Magic”, or whatever that meant, and the “Princess of Friendship”, or something. It was all pretty lost on you.

That was 2 years ago. Since the experiment vessel crashed and they weren't certain on how to get you back, everybody decided to just let you live in Equestria. And in those two years, you became very close with that same pony who first greeted you on that fateful day. As she taught you the ins and outs of daily life in Equestria, you became closer and developed feelings for each other. You’ve been dating for just over a year, and while some people thought it was odd at first, they just shrugged it off. But the oddest thing that’s happened to you happened during a particular lesson.

Despite the cartoony appearance of the land, it was still like Earth. Women (or mares, as they were known) had vaginas, men (stallions) had penises. Same as always. But what you learned, is that princesses, who had both wings and horns, had both. Full sets of everything, all fully functioning. You learned that about 2 months into your romance with Twilight. And you never knew quite what to make of it, but just rolled with it. You weren’t really sexually active for the longest time, a few blowjobs here and there (both giving and receiving), nothing fancy. You tried penetration, in both positions, but nothing serious. But now, on your two-year anniversary, things are about to heat up.

In Equestria, relationships are serious business. To have one with the Princess of Friendship? It’s basically the most important thing in the world. You ended up learning that anniversaries are a big deal when it comes to royalty. So big a deal, is that royal anniversaries of at least one year are basically given a whole week. 7 days of not-as-big celebrations compared to a big one.  So you had no idea what was in store for you as the first day of your anniversary week reared its head.

> 1. The first night
> --------------------------------------------------------------------------

On the first day, things went along as usual. Princess duties, normal day-to-day things. But every time you looked at Twilight, you always wondered what she would have in store for each night. Every time she caught you looking, you would quickly turn your head or see her wink at you. She had something planned, and you didn't know what to think.

5 o clock came around, and the other workers went home for the day, and you two were now left alone in the castle. You went to her office and found a sticky note on the door. 

''Meet me in the bedroom' - Twi'

You already begin to blush, and start to work your way to to the bedroom. By the time you get up there, you find a small vial on top of the bed, which has been perfectly made. The clear bottle is filled with a purple liquid, and has a small "Drink me after taking your clothes off" tag on it. You remove your clothes, throwing them in the hamper in the corner of the room. You twist off the cap on the vial and take a small preparatory breath before downing the entire liquid in one gulp. It doesn't really taste like anything except for sugar, but you immediately feel its effects. It almost feels like your skin is...stretching and becoming a bit more elastic. You don't change shape or anything, but you suddenly feel a lot more bouncy, you guess. 

The door to the bathroom that is connected to your bedroom swings open, and there she is. Twilight steps out, dressed only in a lacy navy bra, the garment caressing her EE breasts, each the size of cantaloupes, and a matching pair of panties. But her panties aren't exactly...covering her up. Her orange-sized testicles  bulge out of the leg holes on either side, the dark purple globes struggling to stay contained by the skimpy lace. Her flaccid horsecock dangles out of the panties, measuring up at 16 inches long, and 8 inches around, a lighter purple than her sheath, but still darker than her fur. As she steps towards you, it swings like a pendulum with the exaggerated gait she uses, moving in a sultry way. Your own member, coming in at just over 7 inches long and 5 around, perks up. You feel light-headed, and wonder if it's the sight of your smoking hot partner, or the potion you were given.

"Ready for a night of fun?", she whispers into your ear.

"Absol-"

"Ah Ah Ah, don't say a word. Tonight, I call the shots."  she says, covering your mouth with her hand.

You're facing away from the side of the bed, just next to it, and Twilight gives you a gentle push backward, helping you fall back on the bed. She unhooks her bra, suggestively dropping it to the floor, and her huge boobs flop out as she removes it, slowly bobbing from the motion.  She moves in towards your mouth, as you both embrace in a kiss, evolving into a slight makeout session at the edge of the bed. Her breasts squish up against your chest, rubbing all over your torso. She breaks the kiss and drops to her knees on the floor, her head at pelvic level. She spreads your legs and moves her mouth towards your dick, kissing it ever so gently. 

"Now just sit back and let me do the work." she says.

She starts with the head, putting her lips over it like a popsicle, sucking slightly and working her lips around the circumference. Her tongue helps out, swabbing the tip. Her hand moves a bit lower, grabbing your balls and just playing with them ever so slightly. You gasp just a bit as they feel a bit tingly, and then, in a single moment, goes down. She goes slow. Taking time to study the ins and outs of your cock. She bobs with care, not to set you off too early. She doesn't go all the way down to start. But as she starts to get faster, she starts to progressively go deeper. She makes it all the way to the bottom, and you feel your dick and balls start to...expand? You look down and your balls haven't grown, but boy do they feel heavier.  Your dick looks just a bit thicker, too. But that might be because Twilight is suddenly deepthroating you, going up and down at a pace that has you short on breath. You slowly move your hand to her head and push ever so gently down, thrusting as she goes down. 

"I'm...going to  - ", you eek out.

She goes down one last time and stays there, your hand slightly pushing her down as you feel a release. The first spurts feel like they're going at light speed our of your dick, as she swallows them down eagerly. She suddenly takes her head off of your dick and grabs it with both hands, aiming the cum shots at her open mouth, face, and hair. They continue for 30 seconds more, as her purple face now has stripes of white covering it, over her nose, forehead, on her horn, and in her hair. 

You fall back on to the bed and gasp. Twilight leans over and kisses you with cum-stained lips, sharing your flavor in a brief kiss. You should be exhausted. But, for some reason, you don't feel tired.

"Now, I think it might be time for my turn." She gets your attention, standing in front of you. Her left hand grips just under the medial ring of her thick shaft, as a white bead of pre-cum is just coming out of her slightly flared tip.

"I would agree", you say in a sexy tone, as she backs off of the bed, allowing you to be face to face, her standing just a bit over you. You slowly drop to your knees, and you can smell the musk she's giving off, mixed with a little bit of sweat from her work on you. You are now at eye level with her horse dick, the head drooping just a bit to meet your gaze. Your hands work their way to her thigh, where the panties she is wearing have a small clip fastening the ends together. You have to reach around her to do it with both hands, and you are nudged closer to her dark package as you undo the clip, and the panties drop to the floor. The slight draft made by the fabric falling sends a whiff of her natural perfume towards your nostrils, and you take a big sniff. Earthy, but not overpowering.  You grab one of the hefty globes as it rests perfectly in your palm, and your thumb works around it, rubbing and caressing it. Your other hand does the same to the other one, massaging her sack. You move your mouth towards the balls and breathe hot air on to each of them, and start sucking on one. You give that one a bit of attention, and then move to the other, alternating for a minute.

The drop of pre has leaked out and has traveled down her shaft to the point where the sheath ends and her dick begins. You see the trail made by it, and slowly lick up her marecock, over the medial ring, ending at the slit where the salty nectar came from. You kiss around that opening, hoping to suck out more of the fluid. You decide it's finally time, and you start to take the head in your mouth. It feels a lot easier this time. You work around the head, tongue slathering the tip, using the same methods she did on you. You begin a slight bob on her dick, trying to lubricate it with your mouth. Your lips feel stretchy going around it, maybe the potion has something to do with it? You start to drop lower, getting to the top of her medial ring, which is where you usually stop. You spend some time going up and down, your tongue slathering every little vein and ridge, a small bulge in your throat showing at this point. You also slowly jack off the bottom of the dick with your hand, working around and getting her more aroused.

"Deeper." she commands.

You remove your mouth from the dick and look up at her with concern, but still have a hand on it. 

"That's what the potion was for. You'll be able to take all of it this time."

You nod slightly, and start to work your way down. You stop at the medial ring, take a deep breath in through your nose, and start to descend. You can feel her penis snake its way down your throat, past your uvula, and start to go down your esophagus. You bring it back out, your throat feeling very empty all of a sudden, when your marefriend grips your head with both hands. You knew this meant something intense.

She shoves you back down her massive member, not holding anything back now. She starts to thrust faster than she did on you, her dense and large balls hitting you in the chin with every stroke, wafting the musky air into your nose, making it the only thing you smell. You grip her thighs to try and gain some control, but she's clearly taking this all the way. You can feel your throat stretching with every thrust, but it doesn't seem to hurt.

She continues this for a minute, and without warning suddenly stops thrusting and holds you there. It hits like a tidal wave. The first volleys come out and go straight down your throat into your stomach, the hot cum feeling like a warm cup of coffee going down, but 10 times as thick. It starts to settle in your stomach, slowly inflating it outwards. Your nose is barely getting any air, and your mouth is obviously occupied, and you feel like you're going to pass out any second now. But for a solid 45 seconds, she holds you there, steady shots of semen flow into you. 

She suddenly backs away and you gasp for air.

"Close your eyes and open your mouth", she demands.

You do so, and just at the right time. A thick rope of pony jizz hits you right across the eyes, as she begins to aim the last of her climax at you. She makes sure to paint your face like a wall, even more than you did to her. One shot quickly fills up your mouth, and you swallow immediately, savoring her sugary, sweet, but salty sperm. More comes your way, as your hair, forehead, eyes, and chin are covered in the thick cream.

"You can open your eyes now" she says, holding your face in her hands. You are barely able to open your eyes due to the viscous fluid, but as you open them, you see Twilight looking right into your eyes. Her royal purple eyes stare back, as she licks some cum off of your face and proceeds to partake in a final, sloppy kiss, this time, sampling her own flavor in the embrace with the cum left in your mouth. Some drips off of your chins and onto your distended stomach, looking 8 months pregnant, and heavier than a bowling ball.

She breaks the kiss, licks her lips, and leaves you there, kneeling and full of cum.

"And that was just the first night."
> 2. The second night
> --------------------------------------------------------------------------

You woke up the next morning, surprisingly tucked into bed, your lover of last night unsurprisingly missing from the spot next to you. Your large stomach had somewhat reduced, and you didn't feel heavy like you thought you would. You didn't appear to gain any weight, so that must have been another effect of the potion. Everything else still felt sticky, however. Hair, face, stomach, everything above nipple level. You hopped into the shower and started to scrub down and get out as much of her cum as you could. You looked for your body wash, but it was missing. Hers was there, so you didn't think twice about yours being missing. You don't really care about "girly" scents, just about getting clean.

You pour some out into your hand, it's a deep blue. You give it a small sniff, and it doesn't appear to be scented. It must be new, you haven't seen it before. You figure it must be something from Rarity, she still does a lot of styling and junk for Twi. You start to rub it all over your hair and face, and pour more out and rub it on your chest to get the stickiness to go away. You suddenly feel a bit of a tingle go across your chest, you feel a bit worried since it didn't smell like there was mint in it. And then your chest starts to feel...softer to the touch. Almost like...it's getting bigger? Oh no. No, it can't be. You throw some water and scrub down below with some hand soap from the sink so you don't have anything wrong happen there. Your chest is still expanding, getting bigger by the second. First A-cups, then B-cups, and last you checked, a healthy C-cup.

You quickly towel yourself off, wrapping the towel...above your new boobs, apparently, and go to try and find Twilight. It doesn't take long for you to find her, she's standing in the doorway leading into the bedroom, and closes the door as she gives you a smirk. You instinctively go to cover your genitals (which remain unchanged, thankfully), and that causes your towel to fall off, exposing your now E-cup breasts, each with a perky nipple pointing out from the rush of cold air after leaving the bathroom.

"What's going on, what's happening to me?" you ask her.

"Well, as a part of the week's festivities, I was going to do a full swap, but it appears you used my special shampoo."

"Special? How special? I used it on my face and hair! What's going to happen to that?" you say, starting to raise your voice a little.

"Just a little of poison joke, nothing serious. They'll be fine, it just decided to go after something else."

"Why even have poison joke shampoo in the first place?"

She chuckles, "Oh, it's great for your hair. Makes it real soft. You just need to have the antidote conditioner, which I happen to be out of."

You start to simmer down a bit. "Well, how long will it last? I can't go out looking like this."

"Just a couple of hours, it doesn't appear you used that much. We should be able to have some...fun in the mean time, though."

"I guess," you reply, a bit miffed that she didn't tell you about it, "what did you have in mind?"

She takes off her modest blazer and unbuttons her blouse, revealing she's going bra-less today. Her pert purple tits swayed back and forth as she moved toward you, the dark purple nipples also erect from the sudden change in environment. She grabs you by the wrist and pulls you toward her, symmetrically docking both of your assets together, nipples rubbing up as she brings you in for a kiss. You both grab onto each others waists (and you slide a hand down towards her ass) and start to make out. You use all of your knowledge of cheesy 80's movies and lesbian porn to try and make this kiss work, and it seems to.  You both spin like some kind of pornographic waltz, ending up with her falling back on the bed and you landing right in front of it, basically just like last night. Your boobs cushioned the fall, so you guess there's one positive result. No concussion.

She must have noticed that, as she is quick to take off her shoes and pants, throwing them who knows where in the room. She quickly removes her underwear, too, throwing that over you, making sure you look back at her to see what she has planned. 

"Wanna get me prepped?" she asks, her half-erect dick flopped out in front of your face. "Use your mouth."

You oblige for the moment, not wanting to end up guzzling cum like the night before. Your mouth tentatively touches the tip and starts to suck lightly, as your head starts to back away as her dick bobs up quickly with the new blood flow coming to it. Precum starts to leak from the tip, and you slurp up a bit of it, reminding you of last night.

"Hold up", she says, backing away from your mouth, "now you need to lube those girls up." she says, pointing to your...girls. You start to pump her now leaky cock with both hands, hoping to coax out some "lubricant." Her dick cooperates, pumping out some which you catch on the top of your breasts, and some on your hands. You start to rub it around, making sure to get between them, as you're now quite certain of what is going to happen next. You get a little more of the foggy-clear precum and rub it on your nipples, feeling just how sensitive they are to the touch and the warm fluid.

"There we go. Now come close. I have to make this count."

You know what she's about to do. You scooch closer to the bed, she scooches closer to the edge of the bed. She leans back so her large horse dick rests over the edge and straight up. You think back to when she's done it for you, and put a boob on each side, just resting them on each thigh. You can't reach the tip with your mouth at this angle, so you bathe the shaft with your tongue and mouth to make it a bit more slippery. 

"You're gonna have to help out too, I've never done this before." You say, not exactly sure of what you're doing. She nods, and she thrusts a bit to get it going, her somehow still heavy testicles slap against the underside of your breasts, as you grab the outside of each one and start to move up and down as best you can. Your saliva and more of her pre start to leak down her shaft and into your cleavage, making the tunnel a bit slipperier for this obstruction. You work your breasts up and down as much of her shaft as you can, seeing that having such big breasts means you have a lot of weight to work with. Your marefriend starts to moan and gasp as your soft titflesh massages her probably still sensitive marecock.

It actually didn't take too long for her to seem close. You look up to see her biting her lip and breathing through her teeth. She's very close.  She starts to thrust with a bit more rhythm, picking up her pace, her balls now pounding the bottom of your boobs, almost hurting them. She gives out one last gasp before...

"Cumming!"

A rope of semen flies a foot and a half into the air, basically straight up, her dick still being supported by your very cushioning chest, and  lands basically back on top of your head and tits. You look up to see the spurt and find another glob goes straight into your mouth and surprises you. Still tasty. Her orgasm must be a lot lighter than last night's, as it finishes in less than 30 seconds, more ropes flying into the air, and her pointing her dick like a cannon and shooting the last few ropes directly on to your fat tits.

"Wow. It's really neat to be on the other end of a boobjob, I should make a note of that." That was your Twilight. Not 30 seconds post orgasm, wanting to take notes.

You both go to shower up, this time with soap that won't give you tits. You both dry off, and you are worried and ask Twilight why your chest hasn't gone back to normal yet.

"Oh no, I was afraid of this." She walks to the bookcase and grabs a blue hardcover book. She flips to a bookmarked page. "Yup, that's what I thought. The poison joke has some special effects that only happen when it touches bare skin, not a coat of fur like we have. I'm afraid there's only one way for you to get back to normal."

"And what's that?" you say, almost knowing what that's going to be.


-------- (An hour later) ------------


"Boy, it sure was nice of Mrs. Cake to let us borrow this for the afternoon!" Twilight says happily. You follow her back into the bedroom, taking off the heavy coat you were wearing to hide your enhancements. You were pretty sure it did nothing, but it made you feel better. She sets the breast pump machine and the two pumps on the nightstand next to the bed. "And she made sure to give us the extra large containers, too!" You were just glad it was an automatic one. "Now sit down and we'll get this over with and have you back to normal. At least then I'll have the ingredients for the antidote!"

"Yaaaay", you say, dryly and sarcastically doing your best imitation of Fluttershy.

You sit down on the armchair next to the nightstand and turn on the TV as she affixes the pumps to your nipples. She turns the machine on and you shiver a bit from the stimulation.

"Just about an hour should do the trick to get all of the spore magic out of your body. Wait a second, you didn't get off during all that, did you?" You shake your head, now engrossed in whatever drivel was on the TV. "Well tell you what, tomorrow, I'll have a special surprise, just for you. It'll be great." She starts to walk away, back to her office, presumably.

"As long as I don't grow tits again." you shout to her as she's walking out.

"I promise!"
> 3. Night number three
> --------------------------------------------------------------------------

After the events of yesterday finished, your chest shrank back to normal, the "milk" that was pumped out was essentially poison joke extract, so Twilight had it re-purposed into more of the conditioner so that the issue wouldn't happen again. Your hair did feel softer and fuller, though. So she wasn't lying about that.  You two both woke up in the same bed this morning, and your day went on as usual. Breakfast and lunch were great, work was also as good as work can be, nothing good or bad stuck out. But throughout the day, you tried to guess what your "special surprise" would be. You tried to goad her into divulging her secret plans, but she was not budging. So she just left you wondering. 

The day ended, other workers packed up and gone home, and you meandered into the study where they had the good armchairs, as you so often did after long days at work. You sat down and just kind of slumped down when something caught your eye. It was a red flower petal, you assumed it was from a rose. A rose petal? you thought, A bit cliche, isn't it? Well, better follow them and see where they lead.

You followed the trail of petals, obviously leading into the bedroom. You slowly open the door, wondering if you're early for the "surprise", or if Twilight would even be there at all. Well, she was. She was lounging on the bed, sporting a skimpy pink robe, loosely tied but still covering up most of her body from the thigh up. You followed the trail of petals on the floor, to the bed, and it ended right at the beginning of her bath robe, right at her groin. 

"You wondered what your 'special surprise' was?" she asked in a sultry tone, "Well, here it is."

She slid off the robe, and where you expected her large package, all you saw was a small triangle patch of navy public fluff pointed down at her lower lips. "Tonight, this is yours." she says. "Go get that bottle of lube from the drawer and come get me ready." You run to the dresser and open the top drawer, which is where you keep the lubricant. You were glad it was going on your dick tonight. You quickly undress, not caring where your clothes went. You walked towards the bed after undressing, and got onto the bed and started to kiss her, holding her head to make sure you stayed close, and slipped your other hand down low. She wasn't really wet just yet, so you had to prep her up. You slid a finger in her, massaging the walls of her vagina and helping her lubricate just a bit.  She moaned quietly into your mouth during the kiss (and really cutely, you thought), as she started to feel a bit wetter. 

She breaks the kiss, grabs the bottle of lubricant from on top of the bed, and squirts some into her palm. She grabs your dick and balls and starts to give you a handjob to get you ready, using both hands; one on your member and the other on your ballsack. The lubricant was clear and unscented, but you felt a tingle as she continued to work it around, and you knew that meant something, something potentially bad. "Is it working yet?" she asks, fully aware that the strange faces your making obviously display that.

"Oh yeah." you quietly in a worried tone, "What's it supposed to do?"

"Just wait for it..."

Not a couple second after she finished talking, you felt it. You saw it in the head of your dick. It started to expand and flatten out, as if it were starting to look like...a horses'. The tingling continued, making it grow every second. You felt it get denser until it felt like it weighed two pounds in your hand, growing almost as big as hers was, growing to over a foot in length and what you thought would be 7 inches around. You never had any real envy for her size, she was a magic royal horse, so most things were possible, and so you wouldn't blame her for wanting you to be a bit bigger every once in a while. It finished its growth and recolored to lighter shade of your slightly-tanned skin, close to pink, as you felt the skin around your dick get a bit heavier, keeping its original color. Your balls were still tingling, so you know they were next.  They started to fill up and expand, like water balloons filling up with heavy cream. They went from their normal chicken egg size, and expanded to be as big as avocados. Your sack started to droop as the pouches contents got bigger and heavier. For the final touch, a medial ring formed just above where your new sheath ended, and a couple veins snaked their way up your new equine member.

All while this was happening, Twilight had taken some of that lube and was fingering herself with it to make her even slipperier and make entrance even better.

"Get up here. It's time for this pony to ride instead of be ridden. I want to feel all of you inside of me."

You slide up on to the bed, and you prop a couple pillows up by the headboard so you don't hurt your self. Twilight slides around you, and stands up on the bed over you. This may be the first time you've been towered over by her without a dick in your face.  She slowly crouches down, touching the tip of your new flat cock to the very edge of her pussy. You both let out a small moan. Neither of you have really felt pleasure like this anymore, thanks to the new larger surface area of your dick. She slowly descends down the pillar of turgid flesh, moaning and exhaling the whole way down. She stops when she gets down to her knees, which put her just past your medial ring, not quite bottoming out. She puts her hands on your thighs to be able to lower herself, and you put your hands on her hips, so you can lower her down. 

"Ready?" you ask, noticing she's adjusted to your size by now.

"As I'll ever be."

She lowers herself all the way down, thanks to a little help from you. You can see a faint bulge above her pubic area, stretching the area under her belly button.  You guess you are that big now. 

"Ooh, we have to try this more often. I've never felt so full!" she gasps.

You start to feel it, too. Her inner walls are amazingly warm and tight, you can almost feel her insides stretching to accommodate you. She pushes off of your legs, going back up to try and take in as much as possible on the way down. She drops back down, you thrust up as it happens, and she lets out a cute little squeak as you push more of you inside of her. She goes back up to feel that sensation again, and the cycle begins. For what seems like 10 minutes, you both are like a well-oiled (lubed?) machine, like dance partners who are amazingly in sync. As she pushes up, you bring your hips down, just to slam them back up into her as she comes down. Your balls slap against her backside, bouncing up and down with every thrust, almost as if they were sloshing full of seed. The synchronized sex continues, when she starts to eek out some words in time with the thrusts. 

"I'm.....going.....to.....cum!"

You feel her vaginal walls contract, as a clear liquid sprays out of her spread-open slit. You suddenly felt yourself flare up inside of her, almost locking yourself inside of her for the time being. Her release was apparently all it took to put you over the edge, as you give a grunt before you release. It's an orgasm like you've never felt before. It comes out like a cannon, feeling like it is a solid line of cum, shooting up into her vagina, and almost feels like it went past her cervix. You hold her down on your spasming dick, as more of your hot seed shoots up into her. She has a second orgasm, just like that, her fluids now mixing with yours at the base of your dick. It was a solid 30 seconds of orgasm, and you even saw her stomach distend some. It felt nice to be on the other end of it for a change.

She is as spent as you are, and falls on to your chest, and slides your dick out of her, growing softer by the second. What you think is about a quarter of a cup of jizz leaks out of her, your cock being the metaphorical plug to her drain. Both of you are breathing heavily, chests going up and down on each other, panting for breath. A minute later, she finally puts her mouth next to your ear.

"That was amazing. And I forgot to mention, there's a part two to the surprise." she whispers into your ear, 

You feel your dick suddenly tingle a bit as she backs off and kneels in front of you, as your manhood looks like it's covered in glitter? You see the same thing happen right where her pubic hair was. It feels like it's...getting smaller. Mus be going back to normal. But what you see starts to worry you. It starts getting even smaller than you remember it. You feel something...open up inside of you, like your skin was being ripped open under your ballsack. A huge pain starts to come from that area, and you reflexively reach for your balls. But they're also getting smaller, or just further away. You look down in horror to see that there is now an opening in your groin, and your balls are going into it! You reach for them to try and hold on, for some reason, and that takes the attention away from your dick, which is still getting even smaller and thinner. Your balls feel like they just moved up into your body and kind of dissolved, while your dick starts to also move near the top of that opening. You know what's happening now, as the edges of the opening are getting redder, and more...petal-shaped. Your dick gets smaller and smaller to where it's just a couple of millimeters long, resting at the top of your newly formed...vagina. 

"What the fuck is this?"

"The surprise, silly. You didn't think you'd get to have all the fun, did you?" she replies back, in a bubbly tone. You also noticed that while you were dealing with your genital change, hers did, too. Or rather, her dick and balls were back. Same as ever. And there was a little bead of pre, all ready to go. "And now, we're going to have a lot of fun, just my way this time." Her horn glows and she snaps her fingers, and what look like handcuffs made out of magic suddenly fasten your wrists above your head, attaching them to the bedposts and leaving you at the mercy of your marefriend, your new equipment getting aroused. 

She lays down on her stomach, her face inches away from your opening. She starts to lick. She licks at the folds from bottom to top, finishing with a small tongue flick of your clitoris. You gasp loudly, almost a scream, as you feel an intense wave of pleasure surge through you. She continues the tongue attention, even slightly pushing it in, which elicits a real scream out of you. It's a good thing this bedroom was soundproofed. She then moves up to the top of your vagina and starts to suck on your clitoris a little bit. It's all clearly too much for you, and you yell and let loose your first female orgasm, legs raising up into the air as a clear, sticky fluid jets out of your vagina and all on to her muzzle and chin. She closes her eyes due to the discharge and the sound of your screaming, and then gets up back on to her knees.

"Tasty." she licks her lips, savoring the taste. "Now that you're all set to go, why don't you get me ready." 

She thrusts her dick in your face, clearly taking charge for reals this time. You quickly nod, scared and horny for what's to come. You open up your mouth, and she wastes no time in sticking it in, thrusting in and out quickly to get a quick spit shine before penetration. She's being rough with your mouth, hopefully she takes it a lot easier on you when it comes to the real thing. She stops working your mouth, and removes her dick, as you gasp for air. She backs away, her tip mere inches away from taking your virginity. "I promise I'll be gentle to start."

"Just to start?"

"Well, we'll see how it goes. Ready?"

"As I'll ever be."

She pushes the tip in, and you shudder, not being able to comprehend what's happening. It was like nothing you've ever felt before. It was different than anal, it was like you were reacting back to what she was doing. She grabs her dick and rotates it around in your opening, making sure to hit some spots right away. 

"Doing okay? Can I keep going?" she asks, looking at the faces you're making.

"Mmhmm." you manage to say through pursed lips, nodding.

She starts to push forward, stretching you open like nothing you've ever felt before. You're watching it go in, and it's one of the oddest, most pleasurable things you've experienced, new sensations popping up with every millisecond of movement. She continues to slide in, moving every so slowly to make sure you aren't being hurt. But then she stops. You almost feel like her tip has hit a wall. That must be the hymen. 

"I'm at the medial ring, and I'm going to push in just a bit harder. Will that be okay?"

All you manage to eek out is the same "mmhmm". You want to close your eyes so you don't see it go in, like getting a shot, but you really want to see it go in. You feel her push a bit harder, as you yelp a bit as you feel your pussy lips expanding to accommodate the larger girth of her mare meat.  You start to look down, and feel a trickle of warm liquid flow down. A few drops of the red liquid start to appear on her dick.

"Is that...blood?" you worriedly ask.

"Yes, just a little. That can happen when you break the hymen. It will be fine." She looks you in the eyes as she says the next sentence, "Trust me. I would never hurt you like that."

You nod, that actually made you feel better. She continues to slide up, you can feel every vein and texture on her cock, and it's still the most glorious thing you've experienced in a long, long time. You suddenly feel her stop after a bit more pushing. 

"I'm all the way in. How do you feel?"

You notice that she's run out of dick to push into you, her balls right up against your butt. You look down to your stomach and see a lump in your stomach that runs past your belly button. You wonder how this is anatomically possible, but realize you're dating a magic horse woman with a penis. She undoes one of the "handcuffs", to your surprise. You reach down and start to feel the bulge, it's very hard, but also soft and comfortable at the same time. 

"I've never felt more full in my entire life. It's really warm and big. I feel so stretched, but so tight."

"That's good, just letting you take a little break before we start."

"You mean?"

"Yup. Get ready to get fucked."

You almost came then and there. She quickly snapped her fingers, and your hand shot back into place, leaving you helpless. And as she stated, she started to pull back , just to the medial ring. "Here we go," she says, hoping you're ready. You thought you were, but clearly weren't as she pushed into you at a harder pace. She hits your insides and you instantly cum. The dick has given you so much pleasure in such little movement, it takes your breath away. You feel a slight leak of her pre-cum in your new...womb, you guess?

"Whoa now, don't go making me bust just yet, we've got a bit more work to do."

You come back down from the short high and she resumes. Her hips pump tenderly, but firmly. She starts slow, but as she goes on, she starts to pick up the pace. She moves up higher on the bed, her chest suddenly level with yours, her head close to yours, but looking down at her entrances and exits from your womanhood. Her thrusting now starts to get more powerful, going harder and stopping as her balls begin to slap your butt, causing your ass cheeks, as well as the rest of you, to ripple and bounce with her movements. Every hip movement is graced with your cries, the "ah! ah! ah!" like a metronome of pleasure. She continues to speed up, as you both get closer to your final orgasm.

"Brace yourself, It's about to come!" she says through bared teeth, thrusting.

She speeds up, two thrusts a second becoming the norm. For some reason, you take your legs and wrap them around her back, pulling her towards you and locking her into place as you feel a new sensation of her flare locking you in place.

"Ahhhh!" you both scream in unison, your orgasm sending waves of pleasure through your body, clamping down on her horsecock, as your legs pull her even closer to your body. She thrusts one last time and stays in that position, hands planted on the bed, as her cock begins to let go. This was a new kind of warmth for your body, one that felt less heavy and more...welcoming. You feel an area near your belly button start to swell, but it's a different feeling from a normal inflation. Her ropes of cum shoot into your body at incredible speeds, feeling even warmer since her dick was firmly lodged into place. She thrusts a few more times as more comes out, as if she's trying to fling her seed into your body.

Her magic finally gives way as she appears to be spent, and your hands drop to the bed. Twilight drops on to your body as you both lay back on the soft mattress, her head on your chest, rising and falling with your heartbeat. You feel her dick getting softer in you, and it slowly begins to slide out as she rolls over, landing next to you on the bed, head still on your chest. A solid cup of sperm leaks out of you, though there's still quite a bit left in you. You put one arm on the bump in your gut, and put the other around your exhausted lover.

"Wow." you break the silence, still gasping for air.

"Yeah, wow." she replies, unusually simple.

"That was a special surprise, you weren't lying." you chuckle, patting your cum gut.

She chuckles back, "You bet it was. How did it feel to be on the other side?"

"It was...interesting. Am I going to get pregnant?" you ask worriedly.

"Nah, you didn't get any ovaries. I could have done that, but decided not to. Baby steps, you know. So, what did you think?"

"I think I want my dick back."

She chuckles. "It'll come back in the morning. Let's just go to sleep. Good night."

"Good night to you, too." You both move in for a kiss, and basically fall asleep right there, on the bed still soaked in cum and sweat. Neither of you minded, it'd be cleaned and ready for another exciting day tomorrow.
> 4. The fourth night [READ DESCRIPTION]
> --------------------------------------------------------------------------

For this one, please read the description. It's a bit weirder. So, if you're unprepared, prepare yourself. And yes, I know this isn't how anatomy works. It's magic. It's a story, It's a magical cartoon pony in a human-ish form. 


You wake up the next morning, groggy, still a bit sweaty and sticky. You look over to your side, and see your girlfriend, still sound asleep. You look down to your groin, and to your delight, you see that your normal human penis and balls are back. You do check under them to see if your other set was down there, but it wasn't. You sighed with relief, being back to completely normal for the time being. You hear a rustling next to you, you guess your sigh was a bit louder than anticipated, and Twilight's purple eyes flutter awake.

"What time is it?" She yawns, stretching her arms out.

You check your phone on the nightstand next to you. 

"Just after 10." you say. "Don't you have important things to do, like at all?"

"Nope. I have small things to do, but important meeting were all scheduled around this week." She leans over and kisses you on the nose.

"Nice. So, what did you have planned for today? It can't get much more different than yesterday, right?"

"Well," she starts, "I was kind of planning to eat you with my dick and turn you into cum."

You didn't know those words could be put into that order to make that certain sentence. That just didn't make sense.

"What? Eat me with your dick? How the hell does that work?"

"It's magic, I ain't gotta explain shit."

"Will I die?"

"Nope," she says, as you imagine her putting on her glasses like a teacher, "You'll slide down my dick which will be enlarged by my magic, fall into one of the testicles, also enlarged, be turned into my cum through some sciency/magicy bullshit, and when I cum you out, you will reform unharmed from the puddle. It takes even less time if I cum into a container, like a condom. Or bathtub."

"So...how long will it take?"

"Eating you would take as long as you want it, and full digestion from solid form to 100% liquid will take a couple of hours. Reformation depends on the container, but you'll be okay by tomorrow. "

"And I will be 100% completely okay afterwards?"

"Yup."

You ponder the situation, thinking that you can trust her, since she wouldn't lie to you. "Fuck it, I'm in. Might as well go all the way if we're getting weird."

"Excellent. Go shower up and I'll get myself ready."

You head to the shower, making sure that you don't grab the poison joke soap again. As you scrub yourself, getting the remnants of last night off of you, you wonder what it's going to be like to be cum. Or if you'll even recognize that you've become cum. You wonder how many people have had those thoughts in the entire history of the universe(s). You could probably count that number on one hand. You hop out of the shower, as clean as you could be for an absentminded shower such as that. You walk out of the bathroom and see Twilight walking over to the bed, when she tosses you a plastic bottle with a pearly liquid in it.

"Drink that," she says, as you fumble to catch it. "It'll make sure you're okay during the process."

"Is this..." you stammer out as you point to the slightly off-white liquid.

"Oh, no. It's just a coincidence, trust me. That's just how the magic reacts with the ingredients."

You shrug, as it wouldn't have been the first time you've swallowed something of that color. You pop the top of the bottle and chug it down. You don't feel anything now, so you pray to Celestia that it works. She sits down and places the bag next to her on the bed and sits at the edge. 

"So what's all in there?"

"Oh, nothing much. Just a couple of magazines, some lube, a spellbook, and one of these."

She pulls out a large, square, flat package from the bag, it looks like a vinyl record sleeve. It has some writing on it: "XXXXXL: Kinky Fucker Size". Oh. It's...that.

"I told you. You reform quicker if you're in a container."

"It's going to be that big?"

"You're literally going inside of it. Of course it is. I just haven't performed the spell yet. I was waiting for you."

"So how is this going to work?"

"I've got a spell. I've got a potion for my stretchiness, like the one I gave you a few days ago, and I've got your hands."

"Alright, let's get this over with." you sigh.

"Now get on your knees and get close. One in each hand."

You kneel down in front of her spread legs, her normal-sized package about a foot in front of her face.  You reach out and grab the purple globes, one in each hand. They're pretty warm, as you would expect. You feel her shudder as you look up and see her down the potion, toss the bottle back, and look back at you.

"Ready?" she says, horn starting to glow.

"As I'll ever be."

A flash of pink comes from her horn. You look down at your hands, holding on to her testicles, and you feel them get warmer. Not hot, but a soothing warmth. A "sweatshirt right out of the dryer" warm. You start to feel them get heavier. A lot heavier. And then they start to expand. Starting at their normal oval orange size, they look like they're inflating. You swear you hear a cartoony sound effect accompanying the change. She wraps her legs around you and pulls you closer to her expanding cum factories.

"You really need to get acquainted with your new home." she says, emphasizing the last two words and stretching them out. "Now give them a kiss. You three need to be best friends."

You start to reach out to grab them, one in each hand, like the last time. But now, they're the size of soccer balls. So you reach out and caress one with both hands, tentatively leaning forward and planting a kiss on it. As you got closer, you swear you could hear them gurgling. Gurgling. Like a pot of water set on the stove top to boil. For some reason, this turns you on like nothing has before, and you start kissing them all over. You even start to lick them a bit. You switch your attention to the other one as it continues to expand. They creak a little bit as the flesh expands. From soccer balls, to basketballs they expand. You continue the worship of the massive spheres, rubbing your hands around them like a crystal ball. And since her package was expanding, it appears that her aroma got a lot heavier, too. It was musky. Not quite a physical cloud, but it could have been. It was earthy. Pungent. Intoxicating. You put your face right up to where her sack met her sheath, grabbed the skin surrounding your face, pulled it over your nose, and took a huge whiff. It was heavenly. Maybe the potion had something to do with it. 

You were so intoxicated, literally, by the size of her balls that you forgot to give some attention to the main course. Her dick had also started to expand. From the 16 inches it started at, to 20. Then to 2 feet. Growing in diameter, from the original 3 inches across, to 5. To 7. It kept its shape, head unflared for the moment. Just like someone started to click and drag on it. Veins went from the width of a shoelace to the width of a permanent marker. She started to pump a bit of pre out. That's when you noticed her dick, as a large glob of pre fell on to your head, dripping down your face. You lick your lips.

"Like that, huh? We'll you're about to get as much as you want soon."

You back off as the last of her growth comes to a stop. Her balls have grown to the size of over-inflated beach balls,  the skin of her sack stretched to the max, and the balls even rested on the floor a bit. Her dick had finally stopped growing, too. It finished at a full 3 feet, still only semi-erect. It was just under the size of that condom wrapper she pulled out. About 11 inches across. You couldn't even think of what her circumference was at that point. She grabs it with both hands and places it between the two reservoirs of spunk.

"So. How do you want to do this. Feet first, or head first?"

"Is there a difference?"

"I'll suck you off if you go feet first."

"I guess you have your answer, then."

"Alrighty, then. So you need to get up over your calves before I can start to get you in there."

Her horn starts to glow, as does her hand, as she moves it to the tip of her massive purple member. She rubs around the head, which appears to open up the slit that you will soon travel into. You stick the tip of your foot in there, and feel it almost clamp down on it. You pull back, amazed that you're about to do this. But her musk is still fogging you mind, so you go to take the plunge for real. You put your foot in, getting it in up near the ankle. You stretch it outward to get your other foot situated. It's very warm. And very slippery. You feel some pre-cum start to come out, it soaks your feet, and splashes up your legs, helping lubricate your entry. You're on your back, and you push yourself forward like you're crab walking. Your ankles are soon engulfed by her horsecock, soon getting soaked in her pre. 

"I've never felt it stretch like this before, it's painful but arousing at the same time." she says, panting, as she feels the penile intruder slide in.

You keep pushing yourself in, moving outward so you can get your somewhat larger calves into her shaft. You can see small bulges in the dick as your feet wiggle around. You're not even to her medial ring yet, which is now the width of a bicycle tire. Your calves are now fully in, and your knees are soon engulfed as you feel yourself being lifted up. You see a pink aura form, and you see Twilight lifting her massively heavy package up with her arms and a little magic. 

"Strength spell and a little bit of levitation. Now, to give you a proper send-off."

She brings you closer, your hands now resting on the sides of her cockhead to prevent you from sliding in before you cum. You're up to your mid-thighs in pony dick, and your balls are resting on her shaft. She begins to suck on your tip, stimulating you further.  She pecks your head with light kisses, making you moan a little bit. She takes no time in taking you in her muzzle, getting halfway down with the first drop. You really can't thrust right now, so it's all up to her to get the job done. She's obviously a pro at this, so she swirls her tongue around your shaft, bathing it in her saliva.  She quickly goes all the way down, the tip of your dick hitting her throat. Her lack of gag reflex makes this pleasurable, as she goes up and down the whole way, as you struggle to hold on to her tip. You almost start to slip a bit, but regain your composure.

"I'm...close! Just a bit...more!" You say, moaning even more as your legs are getting wetter and stickier. She starts to pump out more pre, making your entrance even slicker. 

She pushes forward one last time as you release. You feel glad that it's coming from a dick this time. Your jizz rockets out, starting to fill up her cheeks in the first few shots. She hold that mouthful for your whole orgasm, and 20 seconds later. You look down at her full cheeks, and she makes eye contact with you as she noisily gulps it down, showing you her open mouth. You feel very spent, and your arms give out as you start to slide down even more, your still semi-hard dick propped up against your stomach as you slide down past your genitals, and to your belly button. The warmth is even more comforting at this point, even if it is a bit weird. She has you propped straight up now, and you start to slide down. Your arms get trapped at your sides as you slink down into the penis. You feel the warmth and snugness start to feel hot. Very hot. Your chest feels like a sauna now as it glides down her slit.  Your feet feel a bit less cramped, and you feel like you know what's coming. Her cockflesh reaches your shoulders, and you get anxious.

"Hold up!" you say in a louder tone. Twilight's horn lights up, stopping your descent. "You're sure this is safe. I will come out okay?"

"Absolutely. I know you trust me. You will come out safe." She brings you closer and gives you a kiss on the lips, which you barely have time to react to. "And just one more thing." Her horn glows again as she taps your forehead with it. "Since I won't be able to really hear you through my dick, you can think what you want said and I will hear it. Only the things you want me to hear. Now, I promise it'll be okay. I love you." You both make eye contact, her large purple eyes almost tearing up from a mixture of pleasure, pain, and love.

You start to slide down, the slit forming around your next like a large purple choker. Snug, but not tight. Your head starts to slip in as a spurt of pre comes out, the salty-sweet fluid getting on your lips. You lick them one last time and take a last gulp of fresh air before your mouth and nose slip in. You close your eyes as you feel the wetness hit your like it was being smeared on.

"Wait. Will I be able to breathe in here?" you think/say. "And can I open my eyes?"

"Yes, and Yes.", she thinks/says back. "You will breathe a bit hotter air, and will breathe fine until digestion."

The word "digestion" creeped you out. You switch your focus away from breathing as you feel your legs are suddenly a lot less constricted. Like there's some free space. You start to try and slide a bit faster, as you see the only light above your head go dark-ish as her slit  contracts back to it's normal, non-gaping status. You wiggle your legs to try and get down a bit quicker. As you bend your head down slightly, taking a bit of cum on your lips as it comes off of her inner walls, you see where you'll be landing shortly. Instead of the anatomically correct solid testes, you see what looks like two latex globes with openings in the side. You decide not to question it, recalling the wise words of your lover, "It's magic, I ain't gotta explain shit!". You wiggle your toe down to try and get a feel of your landing spot as the rest of your body stays perfectly straight, like you're planking. In her dick. To the surprise of literally nobody, you feel a thick and sticky substance hit your toes. It's warm. Warm cum. You move to one side to try and get into that one, and as your foot hits the bottom of the cum puddle, you slip. You suddenly shoot down the rest of her shaft and fall back, headfirst on your back into the other testicle, where you end up submerging your head in the sticky cream. 

You slink up and start to cough, wiping away as much cum as you can from your eyes, trying to get the viscous fluid out of your airway. 

"Oof! What the fuck!?" you hear Twilight scream in your thoughts. "What are you doing down there?"

"I slipped." you think bluntly. You slide up to the side, and realize you are now sitting in Twilight's testicles. Again, you must be the only person in history to say something like that. You're now sitting, with your knees close to your chest, arms wrapped around them. You look around, and see mainly just purple flesh and the off-white cum. It's really hot. It's also very musky. Like, the air is just 100% musk. The lake of cum comes up midway to your calves, and feels as hot as a hot tub. No bubbles yet, though.  Which reminds you. "So when will...it start?"

"As soon as I fire this spell off. Are you ready to go?"

"As ready as a person sitting inside of your junk can be. Is it going to hurt?"

"Probably not." You hear a flash of magic go off. "Be ready, it might get a bit hot in there."

You were so taken aback my the "probably" that you almost didn't notice the temperature change. It got a bit hotter, and you started to sweat a bit more. The musk had also started to turn you on, as your dick stood up from the puddle of spunk. You thought that since you were only going to be solid for a little bit more, you might as well crank one out before it goes away. You start to pump your shaft as you look at your arm, which is sweating even more now. But what you see isn't sweat, it's not clear. Oh. So it's happening now. Your skin is slowly starting to get hotter, as it begins to deteriorate.

"So I'm just going to melt like this?" you say.

"Pretty much. Your mind will wander off in like 5 minutes once you've transformed enough, and then the rest of your body will start to dissolve more. It should be painless for both body and mind."

You accept that explanation, and start pumping your dick again. Now it's a race to beat the clock. Your movements are causing your stretchy prison to bulge and sway just a bit. Using her cum as more lube, you feel your skin get hotter and hotter. Your brain starts to fog up with thoughts of pure pleasure. Your other hand, the one not on your dick starts to flop to the side, your bones starting to liquefy into her sperm. Your new, less focused mind finds that super arousing, and your hand on your dick gets faster. You feel the tension start to build up as more and more of your skin starts to soften, from head to toes. slowly flopping motionless into the rising pool of cum. Your brain can think of nothing but cum. Being cum, smelling cum, tasting cum. You release, your meager load hitting the ceiling of Twilight's nutsack, as your head falls down into the pool, your screams of pleasure coming out as bubbles in the bath. You sink, your mind going away to nothing, your genetic material mixing with hers as you sink into unconsciousness. 

"Honey?" Twilight thinks, seeing her large sphere start to slowly stop moving. She hears a bit of a gurgle and some bubbles that give her the response she was looking for. "Well, might as well let this rest until he's completely liquid", as her still enormous dick finally goes soft. She props her legs up on her now exercise-ball sized nut as she feels it move just a bit and opens up a magazine.

A couple of hours later, she wakes up from her nap, throwing her issue of Equestrian Royalty Monthly off of her face, and notices that her testicles have resized themselves with now even amounts of cum, both hers and her boyfriend's digested body. She rubs both of them a bit and moans at the even more sensitive flesh. "Guess it's time to let him out." She grabs the condom from her side and takes off the packaging. She grabs it and slowly slides it down her still huge member as it starts to expand. Her now fully erect cock comes in at just over 3 feet, and her balls both like smaller exercise balls now. "Don't think I'll be able to really use my hands for this one."

She starts to pump a bit with both of her hands near the bottom of her shaft, since the condom made it just over her medial ring, she has about a foot of flesh to work with. There's a bit of precum from before she put on the condom, and that serves as a little bit of lubricant for her hands as she works them up and down and around the circumference of her massive member. Her horn glows as a magical cylinder starts to envelope her dick, moving up and down like an ethereal fleshlight. She takes her hands off and puts them on the bed at her side, bracing herself to focus on this spell. It goes from head to base, massaging and pleasuring the supple flesh. Her magic is guided downward to rub at her massive testicles, prepping them for the exit of the massive amount of fluid. Her magic proves to be super effective, as she starts to buck her hips in time with the magicjob she is giving herself. It gets a bit quicker and her breath gets a bit more ragged, as she pumps for the last few times.

"Cumming!" she yells to absolutely no one, as the dam breaks loose. If you were conscious right now, you would have felt like you had just cum yourself. The pressure released like BBs out of a shotgun. The first waves of cum hit the condom and started to drag the tip down, forcing a balloon of cum to descend to the floor. Twilight was thankful she splurged on the extra-strength ones. Her balls had tightened up, as much as they could, and were continuing to put out spurt after spurt, each one at least a gallon in size. She continued to fill out the condom at an astonishing pace. It was viscous, creamy, and above all, hot. She felt each volley come out and it was almost burning. The condom continued to expand, getting larger and larger by the second, growing large enough to fill 3 kiddie pools full of her essence. Her orgasm finally slows down, her balls shrinking back down to the size of grapefruits. She takes the condom off the tip of her dick as a few drops fall into the open end, making sure not to waste any of her precious lover. Her dick also starts to shrink, going back down to her normal 16 inches. She ties the condom off and lets it sit there for a second while she grabs a towel and wipes the sweat off of her forehead.  

"Better make sure he'll reform quickly."

She gets up and wobbles a bit, not having stood up in about 12 hours now, and feeling a bit light headed, and levitates the condom full of you through the bathroom door. She's careful not to catch it on any edges, making sure you don't get popped until she wants you to be. She levitates you over the bathtub, and after making sure the drain is closed and there aren't any other openings for you to get through, carefully sets the giant condom into the tub. She unties the knot in the condom, and lets it settle, morphing to the shape of the tub, none of you escaping the latex prison. Her horn glows, and she snaps her fingers, a magical scissors cutting the top knot off of the condom, and the reformation spell starts to take effect. She leaves the bathroom, and puts a "do not disturb" sign on the knob, even though she knows no one will be in. Just as a precaution.

"Well, he should be good to go by morning. I'll check on him midway through the night. Sweet dreams, my little cream pie."

She walks over to the bed, undoes the covers, and is asleep by the time she's covered herself up. Tomorrow is going to be another great day.
> 5.1 The morning after the fourth night
> --------------------------------------------------------------------------

Your eyes flutter open, feeling a bit damp. You're looking at the ceiling of the bathroom. You hear a slight beep. You cast your gaze to the stand next to the mirror to find the clock. 8:00, the red glowing numbers say. Your mouth has the faint taste of cum. You try to stretch your arms out, but you aren't moving anywhere. You feel restricted, like you're inside a balloon. Shit, am I still in her balls? Wait, that was real? I was cum? Am I still cum? You look down, to see you're encased in translucent purple latex. You put the pieces together and assume that you're in a condom. But now you're a human. The tip doesn't have a rim like a normal condom does, it looks a bit ragged. On the edge of a tub, there is a pair of scissors with a sticky note left on it. The note reads:

"'This is to help you get out!' - Twi <3"

You appreciate the sentiment, as the latex prison seems to be unaffected by your hands or fingernails. You shimmy an arm up, thankfully a bit slippery due to still being coated in a slight layer of cum and condom's natural lube, and grab the scissors. You slowly snip your way out of the condom, making sure not to nick yourself. You've snipped your way through most of it, and decide to slither away from it. You still feel a bit slick, so you decide standing up is probably not the best option. You ball up the purple latex and it ends up being about the size of a basketball. You decide that's an omen, and you swivel on your butt so you're facing the trash can, and take the shot. Clunk! It gets nothing but can, and you pump your fist slightly. You hear the knob jiggle and the door opens. It's your lovely marefriend, wearing some loose flannel pajama pants that still didn't hide a bit of a bulge. She had on a white tanktop undershirt over it.

"Why hello, my wonderful boyfriend, how did you sleep?"

"Snugly, I guess."

"Wonderful", she chuckles. "Wait, what's up with your hair?"

"My hair? Wh-" you scramble out of the tub carefully, making sure not to slip. You get over to the mirror and are surprised by what you see. Your normal dark-brown mop of hair now has a familiar pink and purple stripe running through it. You run your hand through it, seeing if it's actually real now. You tug a bit at the stripes, to find it hurts just a bit. You turn around to face Twilight and you suddenly feel a bit...taller? Back on Earth, you were pretty average at your normal 6'0" height, but ponies were always just a bit taller than you were. Especially unicorns and alicorns. Twilight, being the newest alicorn, was at about 6'8", so your eyes came up to just about her collarbone area, which sometimes made it hard to concentrate. Now, you're looking straight at her chin. You estimate this makes you about 6'3" or 6'4". And Twilight didn't seem to shrink any, either.  

You look down at your feet to gaze upon your new altitude, and you notice yet another change. You look down at your dick. The skin near the base looks to have darkened, now looking very tan. It seems to have gotten bigger, too. Your feel your balls and they now feel about the size of a extra large egg, the same color as the skin near your base. About the size of one of those large plastic eggs from Easter, you think.  You grab both of them to feel the sudden heftiness. Playing with your junk has caused you to get aroused, and your dick comes sliding out of what you could call your sheath. It's a darker color, but not quite as dark as your "sheath". It's got a flat-ish head with some bumps around the ridge, you estimate it to be about 2.5 inches in diameter. It comes not-so-majestically flopping out and starts to hang there, flaccid it appears to be just a bit smaller than you normally are erect. 

"Fascinating", Twilight says, holding her hand out towards the open door, her hand covered in a purpleish-pink glow as a book and pen come flying towards it, "It appears that since I may have still had some semen in my own testicles as they expanded, and I released some of that into the condom with you from your transformed state, you essentially got some of my traits when you reformed." She scribbles furiously, crouching down to look at your new genitals to observe them. She taps the pen to her chin, thinking for a second.  She drops her pen, and it clinks to the tile floor. "Alright, I want to try something. Hold out your hand toward that pen, and try and summon it. Concentrate really hard to try and get it." You hold your hand out towards it, and stare at it, and you start to concentrate. A very faint, dark amber glow encases your hand like a think glove, and the pen slowly levitates up. You catch it, and you look into each other's eyes in a state of shock.

"eeeeee!" Twilight shrieks, jumping up and down, heavy breasts flopping in her t-shirt (and hefty package making a bit of a bounce in her pants). "You have magic! Albeit, just a bit and nothing too advanced, but it's there!" She levitates the pen out of your hand and into hers and starts scribbling even harder than last time. You still stand there, still naked, looking at your hand, wondering what the everloving fuck just happened.

"So, wait. Since I was in your balls, and some of your jizz mixed with me when I...was...jizz...your DNA somehow mixed with mine? Are you like, my mom or something now?" you ask, trying to get a grip on this situation. 

"Not really. More of a transfusion, if anything. Unless you want me to be your mommy.", she says, her last words getting deeper and more suggestive, as she puts the end of the pen in her mouth.

"I'd rather we not do that, if it's all the same."

"Alright!" she perks back up into her normal voice, writing a few last words in her journal. She closes the book shut with the pen clip tucked on the cover, and uses her magic to push the book back to the shelf. "After this week is over, we are gonna practice that stuff. As for right now, let's do a little hands-on-observation with your addition." She creeps towards you and brings you in for a kiss. You embrace in the lip lock, putting your hands on the back of her head and reciprocating the invitation. She backs away, and licks her lips. "Hmm, that tastes familiar, lets do a little taste test, shall we?" You look behind you and backpedal your way to the toilet, grabbing a towel and throwing it over the cover so you don't slip off. She reaches in the cabinet and grabs a bottle of lube and applies just a bit to her hands to help her get ready. You sit down as gently as you can at the moment.

All the excitement over the magic has caused your dick to recede back into its sheath. As you sit down, Twilight saunters over to you, removing her tank top, letting her tits flop down. You now start to feel a bit more aroused. The tip pokes out of the sheath, as she kneels down in front of you, spreading your legs open so that the goods can breathe. She scoots closer to your new package, and breathes some hot air onto your balls. You shudder a bit, causing even more arousal and more of your shaft to slide out. She takes a big whiff, taking in your new odors mixing with the odors of her cum from last night. It was a musk she hadn't smelled in a long time. It must be the new pheromones or some shit, you think, noticing her wordless approval. She reaches her slightly lubed-up hands towards the jewels and starts to rub them just a bit, one in each hand. She lifts them up in her hands and lets them down, feeling the weight of them, like she was comparing fruits. Her thumbs work circles around them, massaging the tender yet pliable flesh. She leans forward with her muzzle and plants a kiss on one, opening her lips and slightly sucking. She takes that one and starts to repeat that same slight sucking maneuver all over it, popping it in and out of her mouth. She moves her worship on to the next one, tasting the combined tastes of musk, sweat, and her cum.

By now, you're as hard as diamonds, and your new dick is at an impressive 10.5 inches and 3 across, close to as big as the night when you lose your dick. A dollop of pre-cum starts to leak out. It travels to the tip, and starts to fall off the edge, making a string connecting it to the head. The string breaks, hitting Twilight on the nose. She licks it up and brings her head back up to dick level, looking up at you, eyes as wide as saucers after watching her worship your new balls. "Tasty. I guess that means someone's ready, I take it?"

"Mmhmm" you say, nodding your head. "Very much so."

"Good to hear. Cause I certainly am." She sticks her tongue out, and laps at the tip, swiping up the precum still left on your new opening. She grips your dick with both hands, which you thought was really fucking cool, and slowly licks the head like it's an ice cream cone. You shudder just a bit, hands gripping the sides of the toilet seat as you experience these new things. She starts to suck on the head, her tongue slithering across it. You've started to flare a bit, and she takes note of that before she drops down over it. Her mouth managed to slip over it with no troubles or potions or whatever, and you thought that was impressive. She moves up and down over the first inch and a half, and bobs down just a bit lower every time. She keeps getting lower, more of your horsecock invading her maw, as her tongue takes time to explore your new puffier veins, and she hits the start of the medial ring, and suddenly backs off, leaving you panting, cool air rushing towards your now spit-shined tip.

"Why'd you stop?"

"To let you know that we've reached the point of no return." She drops back on to your dick, now going a bit quicker, as she slowly stretches her lips over the medial ring and holds for a second. She now starts the bobbing procedure again, taking 1 step back and 2 steps forward, rotating her mouth around your cock, making sure her tongue hits your sweet spots. She moves a hand down to her pants, and starts to rub her member from over the flannel, as her dick has started to snake down the pants. You take a mental note of her doing so. She keeps dropping, going up and down, up and down more, as she finally gets closer. You now feel your dick hit a slight wall, her throat, as she hits the base of your dick, your dense balls touching her chin. She holds it there, making sure you're watching. You definitely are. You also notice that she's still rubbing herself over the pants.

"We're gonna go a little faster now, alright?" you squeak out, enamored by her deepthroating skills on your new larger slab of horsemeat.

"mmhmm." she hums, mouth and throat still full of dick.

She pulls back to the medial ring, and your hand goes on the back of her head, and you push down. Her natural reflexes push her back up once she's hilted, and she suddenly has lost the battle now. You are in control. You push her down as soon as she bounces up, and you continue the move not so hard that she's gagging, but just enough to where she feels it. Her hands move toward your thighs and grab on both sides, trying to give her some feeling of power. She goes up a bit harder, and you push a bit harder, her lips and throat creating a vacuum seal on your dick. With her grabbing on to your thighs, you release your other hand from the toilet seat and look down to her pants. She is focused on nothing but your cock now, as hers throbs slightly, still confined by the cotton barrier. You reach your hand out and start to wiggle it back and forth, the amber aura complimenting the purple fabric perfectly. The cloud moves over the tube-shaped bulge in her pants, and she moans into your dick, the vibrations causing you to moan back. She starts to move even faster, as does your hand. Up and down on your dick, your magic going back and forth on hers. You can't hold on much  longer, and neither can she. You feel your head start to flare as it almost locks your dick in her mouth, with no way of it escaping.

"I'm...gonna...."

You don't even get the final word out until she goes all the way down your dick, and you hold her there with your hand. Not that she'd want to leave, but just so you don't give her the option. Your balls contract and release their first load, coming out fast. It feels yogurt thick as you see Twilight's eyes roll back into her head, as she screams into your crotch. You hear a faint splurt. She also released, letting out a torrent of seed in her pants, leaking on to the floor and mixing with the off-white tile. You hold her on your dick for close to 30 seconds as your first load is a doozy, causing her stomach to balloon out just a bit in the process. You release your hand from her head and she releases hers from your thighs. You drop your other hand, the telekinetic handjob finished. The final waves of cum finish from her dick, causing a puddle to form on to the floor, and a bigger one soaking through her pants. She falls back and rests against the wall, holding a hand to her bulging stomach. You fall back as much as you can, resting against the toilet tank, dick slowly getting softer with every heartbeat.

"Well," you break the silence, eeking it out between breaths, "how'd I taste?"

"Well," she says, speaking in the same fashion, "Nutty, salty, sweet, and a bit tingly. Say, how'd you know to use your magic like that?"

Your breath has dropped to a normal level now, and you now are speaking a bit more clearly. "Well, if I can't use something like that to jack myself off, there's really no point in it, so I thought I would try it out on a willing partner." You smirk, glancing down at the soaked trousers and glossy floor.

She chuckled back, "Men. I don't know why I expected anything else."

The clock beeped next to the toilet, 9:00.

"Well, we should go to the office and get some work done. I'll show you how to clean that thing up." she says, groaning as she lifts herself up off the floor. 

"Myself? Who's going to clean up this mess?"

"The maids are used to this kind of shit by now."

You shrug and shudder, wondering how many times this has happened.

"Are we still doing something tonight?" you ask, as you walk towards the shower together.

"Oh you bet your ass we are." she says, winking at you.

"Why do I have a feeling that wink was foreboding?"

She tousles the new stripes in your hair. "Oh, shut it."
> 5.2 The night after the morning after the fourth night

Note to readers: read the description. Seriously do it. 



You walked in to your office after getting yourself clean, making a mental note to talk to Rarity to get your pants altered thanks to your new "improvements". You were prepared for a normal workday at your desk, being Twilight's step-above-a-secretary. Answering some emails, taking a few phone calls, that kind of thing. And as the day went on, that's mostly what you did. You got to lunch time and the purple alicorn peeked her head through your door.

"Hey babe, want to grab some lunch?"

"Sure, are we going to the cafeteria, or what did you have in mind?"

"It's a special surprise. Follow me." she says, already starting to move away from the door.

"It's not one like last time, is it? Or are we actually getting lunch?" you say, halting her progress.

"It's actually lunch." she replies, in a mocking defeated tone.

You nod and set your computer to sleep, making sure to lock your office door as Twilight starts to prance down the hallway leading to her office. It was pretty big, with a large CEO-like desk and a few chairs in front of it. The lights were slightly dimmed, and there was a new addition. A small circular table with a white tablecloth over it. There was a fork and knife on one side on one side of the table along with a napkin and a drink glass. There was a drink glass on the other side, too.

"What's this?" you ask.

"Just a little token of appreciation. We haven't really had time to sit down since this week started. I even had them get something special for you."

You wonder what that something special is, as you walk over to the table. You slide the chair out for her and offer it, and she sits down as you go to sit down in your own chair.

A griffin with golden blond back legs, white feathers accented with purple tufts and black hair drops a silver plate with a silver serving cover in front of you, and slowly takes the cover off. A lump wrapped in paper is on the plate, accompanied by a pile of golden french fries next to it, and a small white dish of ketchup is next to it. The waiter had poured you a glass of cola in a glass that looked way too fancy for that beverage.

"This isn't...what I think it is...is it?" you say.

"It might be...have a look!" she giggles.

You unwrap the paper carefully and the smell hits you immediately. A fluffy bun, tomatoes, lettuce, a bit of mayo, and the piece de resistance; Two patties with two slices of cheese. You lift up the bun to make sure it's actually meat. You had gotten used to soy and bean recreations, as they were everywhere in this land made up of herbivores, and you really didn't mind. But you had been having some serious cravings since you saw that the griffon kingdom had actual meat on your last trip, which was just over a year ago.

"Real meat?" you stutter, not believing your eyes or nose.

"Yup. I had a special request to get some from the griffon kingdom, and had one of my chefs with griffon experience help out. I remembered you basically were salivating that entire trip. And I figured some comforts from home might be in order after the stuff that's happened so far this week."

The griffon spoke up, "100% Appleloosan beef, medium cooked, with white cheddar made from the milk from the Sweet Apple Acres farm. Fresh veggies and dressing from the royal garden, a bun from Sugarcube Corner, and Prench fried potatoes, also from the farm."

"Thank you very much" you reply to the waiter, barely taking your eyes off of your food, mouth watering. Your eyes move up to meet the gaze of Twilight, who is watching you ogle this burger, her elbows on the table and chin resting on her hands. "Aren't you having anything?" you say, breaking your eye contact with your sandwich.

"Oh I already ate before coming in here, this is a present just for you."

"So you're just going to watch me eat?"

"Yeah, I want to see how you react to it."

"If you say so." You take the burger, one side in each hand, the paper covering half, reminding you even more of home. Your view now locks on the patties, the earthy tones of the meat, cheese, and bun contrasting with the bright green and red of the toppings.  You move the paper back slightly and move in to take a bite. You close your jaw around the perfect section of the sandwich, making sure to get everything in one bite. As your teeth touch, your eyes widen to the size of saucers.  You chew, feeling the familiar flavor blend together in your mouth. The warm beef and melty cheese collide with the cool lettuce and tomatoes. You chew and swallow, staring at the burger in awe. You hear Twilight giggle, as you look at her. "What?" you say, making sure your mouth is empty.

"Nothing. You just look cute when you're zoned out."

"Oh shut it." you say, grabbing a fry. You dip it in the ketchup, dabbing the tip on her nose before putting it in her mouth. The sudden potato invasion has her flinch back, half a fry hanging out of her mouth. You go back to your burger, taking slow bites and making sure to savor each mouthful. You converse with Twilight during your meal, making sure not to eat too quickly. Stuff about your day, goings on around the castle. 

"So will there be a big party after this week, like with all of your friends and stuff?" you say, having finished your burger and now absentmindedly picking at fries and drinking your pop.

"Yeah, you could say that. Nothing too spectacular."

"So, what do you have planned for tonight?" you inquire, finishing the last of your soda as you hear nothing but ice in the glass.

"I'll be by when the work day is over and let you know. I have some stuff I want to finish first."

Another waiter, this one a pony, comes in to grab your dishes. 

"I trust the dish was to your liking, sir?" he says.

"Very much so, my compliments to the chef." you nod to each other as he grabs the plate and seemingly floats away. You turn to the purple alicorn across from you, "That needs to happen more often. I would suck your dick for one of those again."

"Is that a promise?" she replies, smirking slightly.

"Ehhhh..." you mutter, fanning your hands out and slightly shrugging.

"Well, I have to get back to work, and you should, too." she states, sliding her chair out and stands up, signaling your cue to do the same.  You copy her movements as she snaps her fingers and makes the table decoration disappear in a flash of purple. "Don't worry too much about tonight, just do some work and let me handle it."

You start to worry about tonight, now that she's said that, hoping she doesn't take your previous offer too seriously. You head back to your office, getting any lewd thoughts out of your head for the moment.


~~~~~


You look at the clock and it strikes 6 signaling the end of your work day. You close your laptop and look to your side, taking a moment to take in the sunset through your big window, which happens to overlook the apple orchard. The trees had started to change colors, so it was a beautiful array of greens, yellows, oranges, and reds. Late fall was always bittersweet because the beautiful colors were always offset by the earlier sunsets. You heard a knock at your door. "It's open" you half-yell, expecting who is on the other side.

"All done?"

"Yeah, just finished actually."

"Good." She snaps the blinds closed over the glass facing the office. "Because tonight's events are happening right here. She snaps her fingers and puts a purple barrier on the door. "Nopony will get in, and nopony will hear. Now get those clothes off. All of them."

You quickly oblige to her demands, stripping and throwing your clothes and shoes under the desk. 

"Are you going to undress?"

"No. I prefer to keep mine on." She states, sexily. She's wearing a white blouse with the sleeves rolled up, and a navy skirt that went about 6 inches above her knee. Her blouse was straining from the force of her cleavage. She popped off the top couple buttons, making an obvious attempt at the "sexy boss/teacher" look. You saw a slight bulge in the skirt, seeing it get clearer. a purple tip peeking out of the bottom. That in turn makes your endowment start to bob up. 

"Were you going commando all day?" you say, chuckling slightly.

"Hell no, you know how much this thing would get in the way? I've got vanishing magic for that."

"Would you care to teach me that?" you say, smirking as you shoot her a "if you know what I mean" look.

"Later. Now, we've got some other business to take care of. Now bend over that desk and face the window."

You grab a pile of folders and your laptop and put them under the desk on top of your clothes, as you're sure that you don't need jizz on either of them.

"Are we doing what I think we're doing? Don't you need that stretchy potion for this?" you start to worry.

"Yes and no. I've taken the liberty to mix it with some lubricant."

"So we are doing that." 

"Yes. And I know you haven't taken me all the way in yet, so we'll change that today. Don't worry, I'll go slow."

You hear a cap flip open, you assume it's the lubricant. She takes a little bit and dabs it on her fingers. You feel the cool sensation as she rubs it on your sensitive ring. She lightly presses and pops the tip of her index finger in your ass. You flinch slightly, but it's nothing unusual. She probes around inside, making sure to give it a decent coating, slightly pulling and stretching the skin. She removes her finger from your rear and squirts some more lube on to her hand. You hear a shlick, shlick as she starts to rub all over her dick and balls. It sounds viscous. Your own dick is bobbing from the sound of her prepping herself for entry, clearly ready to get this show on the road.

"So, are you ready?"

"As I'll ever be."

She lays her slick horsecock against your butt, sliding it against the cheeks, thrusting it up. She squirts a bit more lube on your rear end, making it almost slippery with the infused lubricant. You feel some warm drips start to fall on your lower back, you assume it's her precum. That should help with the entry, too. Her balls start to hit your backside, making contact right between your balls and asshole.  She apparently wants to get it nice and slick, grinding her shaft up and down your ample rear.

"Just start putting it in already!" you say through bared teeth.

"If you insist..."

She prods the tip of her dick against your ring, grabbing it and just pushing it to coax  out a bit more of her natural lubricant. 

"1...2...3!"

She puts the tip in, and you feel the effects immediately. Even though you've taken her tip at least a half-dozen times, it never gets any easier. The lube appears to be working, as the slight tension eases itself up not long after she's entered. It's really warm, and you can feel her pre starting to leak more. 

"Are you alright? Give me one knock for yes and two for no. I'll keep going if it's one."

You knock on the desk, not having the mindset to say anything right now. She continues to push in, as you are thankful she hadn't started to flare yet. Another inch disappears into your ass, stretching you even more so as the magical lube continues to work on your insides. You gasp as each bit of hot flesh swabs your insides, making it feel so full. 3 inches becomes 4, 4 becomes 5, and it gets all the way to a larger ring. Her medial ring. She is also panting as she slides in further, making sure you're alright and not too hurt.

"I'm going to have to push a bit harder to get the medial ring in. Are you ready?"

Knock

She pushes slightly, and you let out a little grunt as the half-inch of slightly larger skin makes its way into your hole. She starts to move in a bit quicker, hoping you were too caught up in that to notice her sliding in the rest of her engorged purple member. You apparently were, as you feel a large amount of skin suddenly come in contact with your rear cheeks. 

"You did it! I'm in!"

You stop panting and gasping for a moment to look back, and her hips have met yours. All 16 inches of her are now in your butt, and they haven't destroyed your internal organs yet. Magic, you obviously conclude. You feel so full, it's so different from when it was in your pussy. You look under you to see a large bulge in your stomach area that looks tube-shaped. You also see your rock hard dick is now leaking precum, it's also wanting some kind of release. Twilight and you simultaneously sigh, letting you rest for a minute and to acclimate yourself from having over a foot of pony dick in your asshole.  That's all taken away when she suddenly pulls back, leaving only her tip in your backside. It's now empty. 

"I'm going to start thrusting now, you ready?"

"Yes. I'm ready." you methodically say, exhaling between sentences.

"I'm not going to hold back once we get into it, alright?"

"Go for it."

She enters quickly this time, 13 inches of hard-as-diamond flesh penetrates you. She goes fast, not taking time to care for your butt, which is feeling tingly from the lube. The stretching doesn't hurt as much, but the pace definitely smarts a bit. She slowly pulls back halfway and suddenly thrusts in again. She starts to get in a rhythm, pulling out to the medial ring and going back in again. You feel her hit your prostate with every pump, and your dick is almost flowing precum as it rubs up against the now slick wooden desk, providing even more friction to get yourself off with. She keeps her cadence of in and out going, almost like a metronome. It's heavenly. You feel every vein, nook, and cranny of her dick sliding in and out, the warm flow of pre starting to build up. 

"I'm going to go all the way, be ready."

You tap the desk as she pulls out mostly, again leaving the tip in. She reaches under you with one hand, lifting you up with the other on your hip and grabs hold of your manhood. She pushes back in, moving her hand in the opposite direction down towards the base. She has gone all the way in now, and her balls start to slap your sensitive globes. They feel heavier than normal, they must have gone into overdrive to make up for letting it all out in the condom the previous night. They start to move like a pendulum as she thrusts in and out. You're now lost in pleasure as all 16 inches of her are ramming your ass like there's no tomorrow, and her hand is applying excellent services to your dick. It's clear you're not going to last much longer, as your gasps are getting shorter and more frequent, and she holds in you as you give out one final cry. 

"Cumming!" you say, as her hand hold on to your dick. A shot of sperm flies out and lands on the carpet in front of your desk, a little getting on the large window. Twilight has managed not to cum just yet, although your insides clamping down on her made it really hard. She continues to massage your member as it seems to shrink down after the orgasm. Your hands and legs feel week, and you are confused for a second after you get out of the afterglow.

"Did you cum?" you ask, panting.

"Not yet, but I will. Something's happening." she replies.

You look down and your arms aren't touching the desk anymore, and your legs are also a bit shorter. Twilight is massaging your dick, and you see it almost start to flatten out. You start to taste an odd sensation on your tongue, coming up from the back of your throat. 

"Is that...cum? What the fuck is going on?"

"This is tonight's surprise. That lube wasn't just for stretchiness, it was to help you transform. You're going to spend the evening as my dick." she says, saying it so nonchalantly like she was saying what she had for breakfast that day.

"Your dick." you reply in a monotone. "I'm becoming your penis."

"That's right, just for the night. You'll be slightly sentient, being able to tap into my thoughts, and you'll be normal by morning."

"Fu-ulp-ck it", you say, spitting up a glob of salty-sweet pre-cum. "Let's do it. Go full force."

"As you wish!"

She continues to rub your dick, causing it to mesh with your stomach, balls and everything. She starts to thrust again, as your arms fall limply to your sides, and as your pinkies hit your skin, the flesh sticks together and starts to melt into your torso and hips. Your feet and calves rise into your knees, which rise into your thighs, which start to smooth out into large spheres. She thrusts into you fully one last time as her hips are now sticking to yours. Her balls make contact with your thighs and latch onto each other, and her testicles start to fuse with your former thighs, making them the size of slightly oval basketballs. You feel gallons of hot cum start to build up in the balls, sloshing around. You can practically feel them groaning and sinking with hot seed. As you look down, everything below your hips has turned the same dark purple as her sack and sheath. Your arms have finally receded into your torso as it starts to reshape. Your slightly distended stomach and chest start to shrink and compact into a tube, your belly button becoming an outie, expanding, and starting to wrap around what will become the shaft. The medial ring, you think, as you start to lose thoughts as her thrusting has shifted to two-hand masturbation, more thick pre leaking out of your mouth. 

Your hair sinks back into your head and in your chest as you don't feel like you need to breathe anymore. Your throat has changed from the standard two pipes to one multi-functional tube, as your teeth and lips melt away as you feel the now stream of sexual fluid dance across your mouth-turned slit. Your chest finally stops reforming as below the neck has finished changing shape. It now stands at 30 inches around, just about 10 across. You look down and see a lighter purple color starting to creep up the shaft of the dick. You don't get to see it much longer as your neck snaps up, locking your head in place, looking out over the sunset. 

"Alright," Twilight pants, still rubbing your shaft-body with intensity, "This is it for now, I'll see you tomorrow!" She pulls you up and starts to make out with your mouth-slit, which has shrank into a little opening about the size of a magnum Sharpie. She tongues inside her boyfriend turned penis and samples her flavor. Another spurt of pre hits her in the face as she lowers you down and starts to pump. Your eyes close for the last time as your neck puffs out to match the circumference of the dick, and your face and head flatten out, forming her new bumpy flare. The purple spreads out over your neck and face as Twilight's warm hands slide over her flare, making sure to get all 32 of her new inches. She pumps with a combination of her hands and magic as your soul is still conscious in the giant horse dick. You feel like you're being worshipped right now, and you kind of are. She thrusts the slippery dick in and out of her hands, until she reaches the breaking point. 

She lets loose like a cannon just went off. You weren't ready for the spurt of semen that shot out, it was thick as whole milk and came out in a flash. It splashes against the giant glass window like a thick and sticky Super Soaker. You internally and simultaneously moan with Twilight as the orgasm overtakes you both. Wave after wave of cum comes out of your mouth, like no flavor you've ever tasted before It's sweeter than when you swallow it, not as salty, and even thicker. It's as hot as a fresh cup of coffee, but not burning. She continues to release, coating the giant window with pony spunk, and it starts to drip and glob on to the carpet. Nearly a minute has gone by before she finally finishes, and your body unceremoniously flops on to the slick desk as she plops herself back into her chair. She grabs you and slides you onto her chest, coating her blouse in cum. She kisses your mouth-slit and lets you fall to the ground, where your head is touching the chair mat. 

"I've still got one more surprise tonight." she says to you, as you can hear her, for some reason. "But first, need to let the cleaners know."

She snags a sticky note and a pen out of your desk and writes "Cleaners! HUGE Mess in here! All hands on deck for this one!" She gets up from the chair, groaning from the weight of her new package. Her balls now go past her knees and you now dangle at her ankles, both parts well beyond the hem of her skirt. She walks to the door, and takes one look back at the large window overlooking rows of trees. Except you can't even see the trees due to the large white barrier over the window that's seeped on to the floor below. Thankfully it's not touching anything important. She sticks the note on the outside of the door and grabs her phone. She tries to walk but it's really uncomfortable. She picks you up and hold on to you, pinning you against her shoulder like the strap of a bag. She makes a couple taps on the phone. 

"You ready? I just finished."

"Yeah, I'm ready." the familiar voice responds.

"Sweet, I'll be up in a minute. Make sure you're prepared."

She taps the "end call" button on screen and continues to walk with you in her grasp through the hallways and  saunters down, her huge and still hefty balls colliding with her legs with every step. She makes her way into her bedroom, where she sees a welcome face greet her on her bed, wearing nothing but her fur.

"Well hello Twilight, who do we have here?" the deep blue mare inquires.

"This," she says, shaking your cock-body, "is the new royal scepter, lovingly made from my generous boyfriend."

Luna's mouth begins to water, as does her moist snatch. "So am I going to get to play with him?"

"Oh most certainly." you perk up at hearing Luna's voice. Both you and Twilight had bonded with Luna since all of you had to acclimate to being social in modern Equestria, so you all learned from each other. You had spent nights watching movies or playing games (something Luna had really latched on to), or just sitting and talking. A few sexual things here and there, but nothing this monumental. 

"Bring him to mama." she says, motioning for Twilight to come and present you to the Princess of the Night.

"Yes, Princess." Twilight replies, taking off her soaked skirt and blouse. She sways towards the bed, making her gigantic testicles slosh and gurgle with each step. She stops at the end of the bed and lifts up her hefty globes, resting them on the soft mattress. Luna scoots over to the end and lays her head on one like a pillow, putting her ear to it. Feeling the warmth and hearing the movement of the seed inside of it.  She starts to nuzzle the orb, moving her hands all around the still-slick purple flesh and stimulating them. Twilight shudders and lets out a spurt of precum onto her collarbone, as she is holding you up to give Luna better access to the giant jizz factories. Luna continues to worship the bearers of seed, kissing and licking them all around. She is mesmerized by the scent of the previous orgasm, both yours and Twilight's musk, and the earthy mix of sweat and cum.

Twilight then glides on to the bed, sliding around her nuts and moving towards Luna to give her a kiss. Their ample chests bump up against each other, the massive human-turned-maredick between the four breasts as it curves to avoid the two royal mares locking lips. Luna manages to taste a hint of what's to cum. She licks her lips.

"Delicious. Is that what's on tap tonight?"

"Freshly brewed, right here in the bedroom." Twilight replies, groping her enormous sack. 

Luna moves in to the rapidly-expanding dick, kissing the opening and sticking her tongue in it, hoping to get more of your essence. You subconsciously oblige, spurting more on to her chest and stomach. She responds by taking you and sliding you over her body, using you as a pole of pleasure. It's the largest boob job in history, you oddly muse as you feel her soft fur and hard nipples collide with your flesh, veins, and medial ring. She licks all around it like it's a giant candy cane, but even stickier. Twilight is moaning at every lick, kiss, and rub Luna administers. All 3 of you are in heaven right now, and it's only going to get better.

"Wait!" Twilight says, suddenly separating you from the goddess. She snags her phone. "To: Celestia: Hey ur prob gonna need to raise the moon, Luna and I are a bit occupied ATM" she texts, saying out loud as she types. Her phone dings in response.

"Only because it's your anniversary. And I get it next year."

"Ugh, fine, thx" Twilight sighs as she types back, throwing her phone on to the couch in the bedroom.  You had fallen flaccid as she had typed.

"So, where were we?"

"I was just admiring and worshipping your magnificent pillar of flesh. But now I want more. I want it in me."

You start to fill with blood at the thought of being inserted in a Princess.

"Inside of you?" Twilight asks, shocked. "How."

"It's Princess magic, I ain't gotta explain shit." Luna replies. Both you and Twilight have heard that one before so she decided to go for it, getting as aroused as you both have ever been combined. Luna's light blue magic cloud appears over her pussy as she hides her stallionhood for the night, also stretching out her lower lips as far as possible to prep herself. Twilight now stands 3 feet away, her person-shaft bobbing up to attention, at its near 3 feet in length. A veritable leak of precum flows out like a faucet, and Twilight pokes her tip at Luna's flower. Both ponies shudder as sensitive flesh collides. 

"I'm gonna try and push. Are you sure you want this?"

`	"JUST FUCK US ALREADY!" Luna shouts, the Royal Canterlot Voice making a cameo.

Twilight slides the tip in, and already Luna is stretched to the max. There's no way Twilight is going to get all of it in. Luna already orgasms, being stretched more than anything in her life. Her walls grip the tip and keep it in, hoping to contain the warmth. "Keep...going..." she eeks out, panting already. The purple alicorn (who is more dick than pony at this point) pushes further in. Luna's legs are splayed out at an obtuse angle at this point, bracing for as much of the purple marecock as she can handle. Twilight keeps walking forward, centimeter after centimeter, inch after inch impaling Princess Luna on the giant shaft. Twilight makes it all the way to the medial ring, and the shaft is poking out of Luna's stomach like her flesh is made of spandex.

"Twilight. I want all of that inside of me. I want every tantalizing inch." she manages to say.

"Well okay, then."

Twilight continues to thrust in, getting the medial ring in to Luna's tight pussy. Luna orgasms again as the medial ring stretches her out even further. Twilight reacts to the walls clenching by releasing more thick pre-cum. It starts to balloon Luna's stomach around the massive dick. You can barely take in any feelings other than warmth and tightness, it's the best thing you've ever felt in your life.  You want to stay in Luna's pussy forever. Twilight autonomously obliges, and slides in further. It's almost comical at this point, the stretchiness of Luna's skin showing a large tube-shaped bulge around her  expanding stomach. Twilight keeps pushing. Until her balls hit the bed, and she winces from the pain. She couldn't believe it, and neither could Luna. Her hips moved forward another inch and she was touching hips with the dark blue Alicorn. 

"Holy shit." they both utter.

Twilight wastes no time and immediately pulls out, and Luna's skin goes back to normal aside from the cum-gut. She thrusts back in and goes as deep as she can as quick as she can. Luna is taken aback and has all of the pleasure happen instantly. Twilight has now gotten lost in the magic of "friendship", and begins to pump into her elder friend with vigor that the Night Princess has not felt since her banishment. In and out, over the medial ring each time, balls hitting the bed and Luna's butt every so often, they both pant as quick as they can so they don't pass out just yet.

"I...want...your...FOALS!" Luna gasps out as Twilight makes the older her bitch and broodmare. "I want to be filled." She moves her legs around Twilight's hips and locks the Princess of Friendship in as close as possible.

This was the breaking point. Twilight lost it, right then and there. She thrusted for the last time, the tip of her boyfriend-dick bulging out near Luna's chest, somehow not harming her. Her balls lock up against Luna's pussy, and you feel your head flare out just a bit as a familiar sensation arises. You cum harder than the first time. The warmth, tightness, and intensity of your handler are too much. It comes out thicker, quicker, and even more delicious. You start to fill up the larger alicorn with everything you both can handle. Pump after pump, wave after wave of thick foal-batter. After a minute, Luna looks like she swallowed an over-inflated exercise ball. You finally slide out of her love canal and fall on to the floor, a torrent of sperm making it's way on to the floor. Twilight turns around and falls on to the bed on her back, as you flop on to her chest, and she is lying next to Luna. She kisses Luna on the nose as Luna's eyes open and meet Twilight's gaze. 

"So did I actually get you pregnant?" Twilight gasps.

"Maybe, maybe not. We'll have to see. All I know is we'd be great mothers, and a certain guy would make a great father."

Luna pats what she can of her taut tummy, as they kiss again and both fall to sleep, and you flop on Twilight's chest between her breasts, sleeping the night away.
> 6. The second to last night
> --------------------------------------------------------------------------

A bright light hits your eyes as Celestia's sun peeks through the curtains of the bedroom. Your eyes flutter open as you take in your surroundings. You smack your lips together, and unsurprisingly, they taste like cum. You vaguely recall being turned into Twilight's dick last night, and have even less memory of fucking the absolute shit out of Luna.  You move your head to find that you aren't resting on pillows, at least not ones filled with feathers. You're still between Twilight's boobs, but you are able to look down and see that you're back to your human form. You glance to the side to see the Princess of the Night, silently snoring while sleeping on her back, as some magical alicorn bullshit shrank her stomach to just about a 7-month pregnancy size. You feel super weak, probably from that full-body workout you received, your legs feeling the weakest of all. 

You hear an inhale come from above you as the stomach and chest you are laying on suddenly inflate, deflating as the purple alicorn comes to. 

"Well, good morning. I guess the effects wore off. How are you doing?" she says, quietly enough not to wake Luna.

"Considering I was just a penis for some 16 hours, pretty decent." you whisper back.

"I can promise you that you will not be going inside of me or merging with me any more times this week. And you can trust me on that."

"I hope so, because it's been enough fun for a whole month, let alone consecutive days."

"Just two more days to go, then." she says. "Today, we'll be working off some of that excess padding from our adventures in a more traditional fashion."

"How so?" you ask, looking down at your slightly flabby gut, which has been increased in mass by several rounds of Twilight's essence.

"You're going to be joining me for the usual workout today."

You forgot today was your weekly "couples workout day". This was the one day a week where you did a workout together as her schedule was normally hectic as a princess. It wasn't anything serious, some basic cardio. Hopefully this workout was the only thing that would test your body today. You heard another sigh as the dark blue pony awoke. 

"Good morning, you two. It looks like you both got as good of a sleep as I did." she says, her normally flowing mane still and floppy.

"I guess so." you reply. "Say, we're about to go for our workout this morning, care to join us?"

"Not today, I think I need to let this", she says, patting her stomach, "rest for a bit. Why don't you two go work out, I'll invite Tia, and we can just sit in tonight, order a pizza, and watch a movie? I think we both need a breather after the last few days."

"That sounds wonderful!" Twilight says, ears perking up. "We'll be back in a couple hours, and then we can start getting 'ready for bed'", she says, making air quotes in allusion to the fact that it's like noon. 

"Can I choose the pizza?" you ask, hoping to get something going your way. 

They both nod in agreement. "I think you deserve at least that." says Twilight, giggling as she slides off of the bed.

"I'm going to go shower and then see what I missed last night. I must thank Tia for taking care of my duties. See you later!" Luna says before walking into the large bathroom.

"See ya!" you both say, in unison. 

"Now drink this, you need to replace pretty much every fluid in your body and it won't be good to be working out on an empty stomach."

She has started walking to her closet and tossed you a (oddly, but probably magically) cold bottle of a dark blue drink. You look at the label. "Hayterade." The logo was stalks of wheat in the shape of a lightning bolt, the flavor was called "Nightmare Moonberry." You scoff at the stupid pun and name as you crack the bottle open, the cap twisting off easier than it normally does.

"This isn't gonna make me, like a part of your boobs, or gonna turn me in to your workout shorts, is it? It's a regular sports drink?"

"It's not 'regular', but it's magically enhanced to make you feel better right away and to make sure you can always breathe, no matter the conditions or environment. No super weird stuff going on." she says, rummaging through her armoire for her workout stuff. You took the orange cap off and took a big gulp, as you watched her ass sway back and forth as she searched for clothes. If there was one thing you loved more than anything else on her body, it was her ass. It was pretty great. You downed the blue-flavored drink as you noticed a bit of a tingle. She told you it was magically enhanced so you thought nothing of it. You got about halfway through the bottle before you instantly felt better than you ever have this week. Your stomach started to shrink back to a more normal size, your legs felt like they actually had bones and muscles again, and your eyes shot open. 

"Wow, this stuff is great? This is just  available to the general public?"

"Basically. But most people really only need a drink or two before feeling how you are. Most people haven't been as dehydrated as you were from the past few days. You know, all the cumming and stuff." she walks back towards you, now in her workout gear. She's now wearing a black sports bra and matching black shorts that barely make it to her mid-thigh. Her hair is done back in a ponytail with a sweatband right above her forehead. As your eyes made their way down from head to her legs, a certain something caught your eye. It almost looked like she had a built in "pocket" for her junk. You nearly spit take with the sports drink as your eyes make contact with her bulge.

"So...are those...'specially made?'"

"Oh, these? Yeah, Rarity has made these for me, they keep things 'maintained' and it doesn't move around too much. Like a built-in jock strap. They also contain a special charm that prevents me from getting 'excited' while I'm working out. Helps me keep focus."

You finish the last of the sports drink as your eyes move away from the bulge. As soon as you had finished it, you started to feel really good. Like you just were filled with energy. You felt compact, like a wind up toy that had just been twisted a hundred times. You then realized that you were still naked, and you should probably get some workout clothes on.

"Are you done with your drink yet?" Twilight calls out as she is slipping on some leg sleeves.

"Just finished it, I'll get some clothes on and we can get going." You reply, rotating on your butt to slide off the bed.

"I'd hold on just a second before you get up."

"What for?" you ask, as the answer is immediately made clear to you.

Twilight walks back to the bed, and from your point of view, she seems to be...getting bigger? You then look down at the bed and realize that she isn't getting bigger, but you are getting smaller! "Twilight, what the fuck is going on? Did you fuck with this stuff?"

"Just a little bit, it's probably my favorite trope." She winks, you're not sure to whom she was winking. "It actually is a recovery drink, meant for after physical activities, and it is meant to shrink you for a while. But the more you drink, the more you recover, and the longer you stay small. I modified it with the breathing stuff and a couple other things, but most of it should be the same. I think you'll stay small for about...oh 3 hours or so."

"Well, this isn't the weirdest thing to happen, so I guess I can roll with it. How small am I going to get?"

"Well, the drink shrinks you to the same size no matter what, so just about 3 to 4 inches."

You feel yourself start to shrink even more. Twilight starts to get a lot bigger as the bigger than a king size bed looks like it's the size of several football fields all arranged in a large rectangle. Strangely enough, your body doesn't really feel any different, you're just smaller. No vertigo, no motion sickness from the 90% decrease in size, just the same feeling of being refreshed. The bed does feel a bit softer since you're not sinking into it like with your normal body. You feel yourself stop at your new height, and her estimates of 3 to 4 inches felt right. 

"So what are we going to do while we wait for me to get back to regular size?" you ask, shouting so your new giantess of a girlfriend can hear you.

"Oh, we're still working out. I had planned for this, you're still going to be my workout partner, you'll just be a lot closer."

"What does that me-WHOAAAA" you say as the purple alicorn picks you up and holds you like an action figure.  You sit in her palm as her thumb covers your chest as you rest your arms on it like a ledge. "What does that mean? What are you gonna do with me? I thought I wasn't going inside you anymore."

"Oh, you're not. But you are going in something." she says, as she lowers you down. You look over her hands as her other hand stretches our her compression shorts.

"Ah, fuck. Am I going where I think I'm going?"

"You learn so quickly. Don't worry, you'll be able to breathe."

"Just don't drop me." you say , coming to terms with your fate. 

"Wasn't planning on it." She touches the top of your head with her thumb, and you suddenly heard the end of that sentence clear as day. She must have linked your brain to hers so you can communicate.

You are now lowered closer towards her shorts as the waistband stays open, displaying the special pocket and her special package. You take one final breath as she lowers you into the pouch in the front, mere inches away from your new acquaintance for the foreseeable future.

"And don't snap the-" SNAP! You are interrupted by the sudden jerking of the waistband and the stretchy fabric as the waistband snaps to her hips, and you fly towards her sheath and balls at high speeds. You collide with her jewels at thrill-ride speeds, and you both grimace as you hit the sensitive flesh.

"Oof!" you both say, as her balls are poked at by your body. 

'What the hell?" you say, now trapped between the spandex and her dick. "I just said  not to snap them back.

"Yeah," she says, in between grimaces, "I should have guessed that it would hurt. Ugh, well, I hope you enjoy it for the next hour or so. I won't be too rough, but you will be able to breath and not get motion sickness. So it'll be somewhat okay. The 'bad' news, if you think it's actually bad, is that one of the modifications I put on that drink is that the air isn't automatically purified. So you'll still be able to 'smell me', if you know what I mean."

"I could have guessed that." After the short trip and being smushed up against the alicorn's horsecock, you now take a moment to look at your surroundings.  You were kind of sitting, kind of in the fetal position, nestled up against her ballsack, which was surprisingly soft. Her two baseball-sized nuts were like the trees that held up the hammock of her scrotum flesh, and they had a really distinct odor to them. Like, really distinct. She was definitely right about there not being any purifying, it was like a dank sauna where the steam was made from cum instead of water. You could sense some of Twilight's natural lavender scent, and you swore you smelled something else, like a blackberry. Maybe that was Luna still lingering. Her balls were still sweaty, but that must have been from the night before, as it wasn't wet, just a bit damp. You were afraid as to what that meant for the later portion of her workout.

Your thoughts were interrupted as the pocket you were trapped in suddenly started to bounce a bit. Twilight had started to walk towards her bedroom door towards the gym area, and you bounced slightly with every step she took. It didn't really hurt, it was just a bit unexpected. "Hey, could you just teleport there? I don't want to bounce too much before your workout actually starts."

"Oh! Sure, You'll have to grab one of my fingers though, you've gotta hold someone's hand when teleporting with them or else it won't work. Let me know when you've got one so I don't have my hand in my pants for too long." Twilight looks around nervously as she quickly realized she was still in her room. She shoved a hand down her shorts as a monstrous purple hand appeared in front of you. You grabbed as much of her index finger as you could.

"Alright, got it!" As soon as you finished speaking, there was a pinkish flash of light, and you suddenly felt a breeze hit you. It felt nice. Twilight's hand moved away, and you got to feel more of the cool breeze. It felt good, since you were feeling a bit warm, being packed up against her junk and all. You were now at a closed-off location used as a facility to train royal guard members, as well as hosting events here and there. Today, you were the only ones out there. There was a track, a field in the middle, used for hoofball and other activities, and some bleachers. A simple stadium-type area, but deserted. It was a brisk afternoon, probably in the mid-50's, you both loved this kind of weather. Not too cold, but not too hot. You were both a fan of hoodies, and you were especially a fan of yoga pants.

Twilight took in the scenery for less time than you would have liked, but you really couldn't protest. She walked over to the edge of the field and started to do some stretches.  Lots of leg stretches, since you usually ran at this track area. She stretched her legs out, and you felt the pouch that held her junk hanging there, vulnerable to the breeze.	You feel yourself shift with every pose she makes, but stay oddly secure when packed up against her bulge. The cool breeze is taking away a bit of her scent, but you still smell it, being so tight against it. She finally starts to walk to the track, and gets ready to run. You brace yourself as she stops to get the jog started, and it come sooner than expected. She starts with a light jog as she usually does, and after half a lap, she picks up the pace. All the while, you're bouncing but not feeling any pain. Laying in the bean-bag like pouch of her sack is oddly comfortable, and you only feel slight bumps with every stride and step. 

The run lasts for a good 30 minutes, and you're able to still have a decent conversation with her despite the jostling and bumpiness. Talks about what's going to happen after this week, in both your relationship and her duties as princess. All that dumb stuff. As her workout kept going, the sun rose a bit higher, and she sweat a bit more. Now it was starting to get a bit toastier and damp. It still felt like a sauna, so you just rolled with it. Not that you had many other choices. She slowed down and came to a stop at the end of her run, and made her way over to the bleachers where she summoned a water bottle and had a drink to sit down with. As she sat down, she popped open the waistband of her shorts and looked down at you.

"You still doing alright down there?" she asked, in between gulps of water.

"As good as I can be. How much longer are you going to be working out?"

"I'll just be finishing with some body weight stuff, nothing major. I'm taking it easier because of you."

"Well don't be too long, it's starting to get wet down here."

She chuckles, "I won't. You'll still be able to breathe, though. That Hayterade is good stuff."

"I hope so. Alright, just make sure not to snap the waistband this time."

Twilight now gently closes her waistband and makes her way towards the field in the middle. It's luxurious green grass, presumably kept up with magic to stay soft and green all year. She sat down on the grass and it was still pretty cool. You appreciated that, as you were getting a bit hot down there. The rest of her workout was pretty uneventful, and wasn't all that bad. Some sit-ups, push-ups (which did get a bit weird since you were sandwiched between her dick and the ground with every rep), planks, a lot of basic stuff. Normally, you two would get a bit more intense, but you were tiny. 

Her workout ended, and she started to walk back up to her room as a part of the cooldown. You now were basically covered in sweat and stank like crazy. Hopefully the stench didn't amplify once you were big again. You wondered when that would be. As Twilight made her way up the steps and into her room, she saw a familiar multi-hued tail slide into her room as she got to the top of the staircase. 

"Oh, WOW!" That SURE was a GREAT WORKOUT, HUH?" she says, emphasizing certain words to let the ponies in the bedroom know she was close by. The door slams as she gets close and Twilight takes her time to walk up to the door. She knocks loudly.

"Who is it?" a voice asks. You're not too sure who, since your ears are muffled by spandex and testicles.

"I don't know why I'm doing this, since this is my bedroom."

"Oh come in. Ruining the fun."

Twilight opens the door and sees, to her surprise, both Luna and Celestia sitting on the bed. Celestia is in a pink set of lacy panties and bra, which match part of her mane. The bra struggles to hold in her massive breasts, ones even bigger than any of the other princesses. And her panties are also struggling. Her package is fully ready to go already, her dick coming in at just over 18 inches. The pink lingerie contrasts with the white shaft and light gray sheath, going down to her cantaloupe-sized testicles. They're not normally that big, but she was obviously prepared for tonight. 

"Do you like what you see?" Luna says in a sultry voice. Luna had on just a cream colored sweater. An odd sweater at that. It wrapped around her neck like it was a turtleneck and was tied off, but had no back. Until it got to her butt, where it wrapped around close to half of her cheeks at the hip, the black splotches and part of her moons covered up.  The front covered her also large breasts, which ranked 2nd out of the  4 adult princesses in size. It also covered her still bulging stomach, which was almost back to normal size. There was also a slight bulge on the front, as something was caught between her stomach and the sweater. Her sack, however, was left uncovered.  Coming in at 17 inches, her dick was also second out of the 4 adult princesses. The dark navy went well with her lighter navy fur, which covered her also large testicles. They were softball sized, and she came even more than Twilight could. 

"Luna, where did you get that sweater?" Twilight says, already taking off her sports bra and sweatbands.

"This sweater has been the biggest thing this past week online, so I just had to get one for myself. Rarity is always so quick with these things." she says. "But enough about me, Twilight dearest, might I ask as to what's making that bulge on the front of your shorts?"

"I think you know very well what, or who, is making that bulge."

Celestia blushed. "Twilight," the sun Alicorn started, "Is that...who I think it is?"

"If who you think it is, is my wonderfully willing partner, then yes. I got him with some spiked Hayterade."

"Twilight, you trickster," Celestia said. Might we see how he's...coming along?"

"Certainly." Twilight takes the opportunity to walk towards the bed, still sweaty and tired from her workout, and slowly removes her shorts, making sure you stay perched on her now churning testicles. They appear to have grown after being set free from the enchanted workout gear. She slid onto the bed and sat down, still keeping you on her sack. As Celestia and Luna started to bend down to inspect Twilight's tiny passenger, she quickly shot out a spark of magic at both Luna and Celestia so that they could communicate with you without rupturing your ear drums. They backed away quickly as the magic startled them. "Sorry," Twilight says, "I don't need you making my boyfriend go deaf."

"Here," you say, grunting as you try your best to stand up on the leathery purple flesh, "I'll get off so we can talk easier."

You gathered all the strength you could to jump off of Twilight's sack on to the bed, but it was hard considering it was like trying to jump off of a moving ball of sand. You fall off of the testicular cliff and land on the bed, the soft comforter cushioning your fall as you tumble over. You stand up now, looking at the two princesses of the sky towering over you. They had now shifted to lying down on their stomachs, like how teenage girls would at slumber parties. 

"So," Luna says, her two-toned blue eyes staring at you, "Did you enjoy your workout? It sure smells like you did." She takes a big whiff of you, coated in musk and sweat.  She kisses you on the head, trying to get a taste. 

"It sure looks like he did," Celestia continues in a sultry tone, leaning into you. "I think we're definitely going to have some fun." She grabs you and places you in her palm, and drags her tongue from your toes to your head, savoring the taste of both your and Twilight's essence. You shudder as her soft pink tongue slathers your body in her saliva. It tastes and smells vaguely like strawberries. Her tastebuds slide across your skin like the least gritty sandpaper you could imagine. It scratches all of your itches while slightly stimulating your member, only millimeters long at this point. She sets you back down as you sit down, trying to analyze what just happened. You feel yourself tingle a bit as you grow. Just about 3 inches, leaving you close to 7 inches tall. 

"Oh, shit", Twilight mutters, "The effects must be wearing off. If my assumptions are correct, we have just under a couple hours until he's back to normal. Why don't you two get each other...ready while I grab the supplies." she says, pointing at Luna and Celestia. Twilight ran off to the edge of her bedroom to a drawer while Luna reached down towards her sister's groin. 

"You heard her," the Princess of the Night" said, "We should get...ready." She slowly reaches down towards the side of Celestia's panties, where there was a simple clasp that Luna dramatically reached for it, bringing her muzzle close to her sister's package. She nuzzles the bulge made by her testicles before unhooking her panties and throwing them across the room. Celestia's light gray orbs come spilling out, the skin around her hefty globes expanding and twitching with her increasing heart rate. Luna pulls the package closer to her face and takes a whiff. The smell was clean. Nothing except for Tia's natural odor, which was a familiar strawberry. 

Celestia shudders at the sudden groping. They didn't always partake in the act they had come to know as "princest", but it always felt special when they did. She bit down on her lip as Luna continued to rub her hands around everything except for her shaft. The sheath, the balls, the skin around them, all got the sensual massage. Luna always made sure her hands were moisturized, and that showed. Luna got on to her knees, licked her lips, and gave Celestia's tip a wet smooch before she dropped down onto the shaft. Celestia gasped and grabbed on to the bedspread, clearly unprepared for the oral assault. Luna went all the way down on the first try, stopping to tongue the medial ring just a bit on the way down and the way up. Celestia forgot she was a master of the deep throat, taking in all of the near-19 inches of cock. Luna removed her head from the dick leaving the air to chill Celestia's saliva-coated dick. Luna giggled as she watched her sister's face. 

"Luna, you tease," Celestia says, thrusting her hips to give Luna a slight cocksmack. The dense marecock smacked Luna on the nose, leaving a string of pre-cum between Luna's nose and Celestia's urethra. Luna broke the string with her tongue as she licked the clear liquid off of her nose. Celestia always tasted a bit like powdered sugar, but with a pinch of salt. Luna went back in to Celestia's dick but this time simply licked around the shaft and kissed it, lubing it up just a bit. 

"Oh, how rude of me! We didn't ask our audience if they cared to sample!" Celestia says with fake shock, as she moves her dick away from Luna and slides it slides it on to the bed as she looks down at you. You are now face to "face" with the alabaster pillar, her cock tip clogged with precum. You tentatively walk forward as you gaze into the abyss, the puddle of precum looking rather inviting. You move closer and grab at the head by the sides, and you start to lick the opening. You have to resist plunging your head all the way in, the scent and taste are so inviting. Her precum isn't too viscous, so you don't feel too weighed down by it as you lap up the sweet treat. To your surprise, she bucks just a little, sending a string of the liquid at your face, and you're now coated in it from head to toe. Another rope cums out, and you hit the bed as you start to soak in the sexual fluid. 

"Oh, my. I think someone needs to be cleaned up, don't you, sister?"

"Of course", Luna says.  Celestia asks as she picks you up by the legs. You dangle upside down as you are lifted above Celestia's head, and she opens up her mouth so wide you can see all of her teeth. She slowly lowers your head into her mouth, just past her lips, as she sucks on your head like a lollipop. She slides you in until your chest is on her lips, and she brings her head down as she lets you go. You flair your legs wildly until you feel a warm wind against them. Luna starts to take your feet into her mouth, and slides further up your body, licking all around to clean you of Celestia's precum. She gets closer until the two sisters kiss, your body trapped between them. You feel surprisingly okay, just a bit sticky. The Hayterade must still be giving you breath. Their tongues dance around your body, not even caring about the false pretense of cleanliness anymore. It's simply just for your pleasure. You're being rolled around in their mouths, and one tongue manages to find your member, which has been as hard as diamond for some time now. Your tiny libido and trigger can barely take 5 seconds of that attention before you cum. You spurt your seed into Luna's mouth, who immediately transfers some to Celestia's as they swap more than just spit. 

"Ah-hem." Twilight says as Luna whips her head around, taking you out of Celestia's mouth in the process. She looks at your girlfriend with surprised eyes as you dangle out of her mouth like a spaghetti noodle. Twilight stifles a chuckle at the scene. "I would appreciate it if you wouldn't swallow my boyfriend..." Luna smiles with you in her mouth and Celestia blushes. "Without giving me a taste." she continues as she leans on to the bed. She leans on to the bed and lifts you up with her tongue, getting one look at you before sliding your upper body into her mouth. She gives you the same treatment Celestia did, treating your head and chest like a doctor's office sucker, tasting the saliva of her mentor. You were surprisingly okay with this, considering that none of the 3 princesses breath stank, and the tongue bath was oddly soothing. You got a shock of cold air as Twilight pulled your legs out of Celestia's out, and the cool air rushed against your now-exposed legs.  You hear a slight noise as you assume she's acquired the stuff from the drawer, and she grabs your legs and pulls you out, running her tongue along your head one last time. You finally get a look at what she grabbed as you regained your senses. It was a bottle of lubricant and an XXL condom. 

"Ready for the real fun?" she says, grabbing the bottle. She squirts a bit out, coaxing her own dick to become erect. She slathers on the slick fluid and you are hypnotized by the way she moves her hand around her growing horsecock. The schlick, schlick, schlick of her hand movements have caused the dicks of the other two alicorns to grow to full mast, as well. Celestia begins to drip precum more liberally now, and Luna is just getting hard. Twilight appears to be okay with the level of lubrication, and grabs two palmfuls of lubricant and begins to help out the other two mares get ready. The two older women gasp as the slender hand of the purple pony grasps their shaft, the sensitive tips being massaged by the lube. They both quickly rise to their full attention, the two stallionhoods bobbing, and the full and heavy testicles churning in anticipation. Lastly, Twilight takes one last squirt of lubricant and grabs you, slathering you in it. It almost has a soapy smell to it, but doesn't taste like it, thankfully. 

"Why are you lubing me up?", you say, worried about where you're going. "You said I wasn't going in anything!"

"Oh, you're not." Twilight says. "You're going between something." The three princesses all scoot together, almost on top of each other. They move their hips forward, touching their massive rods together like an offering to Aphrodite.  They are all squished together, the lubricant and precum mixing together to make the heads and shafts almost shiny. They all tessellate well together, just with an opening in the middle. Twilight picks you up and to nobody's surprise, slides you into that opening like it was meant for you. You slide up to your armpits, where you stick out your arms and rest on the convergence of cocks before the fun begins. "The Hayterade should still be working for as long as we'll last, so you should still be able to breathe once we're all set to go." Twilight says.

"There's more?" you ask, smelling a combination of lube and musk. 

"Just one more thing." She pulls out the condom, "XXL: Not quite as kinky, but still pretty kinky" it says on the wrapper. She takes it out, and stretches it as much as she can, slowly bringing it down the tips of all 3 shafts. It stays stretched out, and starts to almost act like shrink wrap as she moves it farther down. Luna and Celestia shudder at the latex cocoon their dicks are how being encased in, and more precum comes out of all 3 heads, causing you to slip off of the tip, not falling very far as you now rest at the top of their shafts, just below the head. The canopy of their flares is just starting to expand, and you hope you stay braced between the penises. Twilight finishes rolling the condom down and sighs, making sure the other two know that she's ready to go. 

"You girls know the spells?" Twilight inquires.

"Why wouldn't we?" Celestia answers, "We're like 50 times your age."

"Point taken. Well, let's get going then. Everybody go clockwise."

Twilight lets out a small moan as a golden aura in the shape of a hand envelops her dick, sliding up and down at a steady pace. Her own pink cloud does the same to Luna's rod, and the navy mare uses her navy magic to pleasure her sister. The 3 go slow to start. Luna starts just a bit faster, knowing her sister takes a bit more effort to go than most. All three throw their heads back in pleasure, as they start to pump more and more precum, flowing freely down towards you, and filling the reservoir tip of the condom more. Celestia decides to go the extra mile, and her aura contorts itself a bit more now, as she ramps up her magic. She now has control over both Luna's and Twilight's dick, also sweeping you in like a tractor beam. You now move up and down between the dicks, and you reach your arms out forward so grab on to one of them. You lock your arms and legs onto Twilight's, as it's the "smallest" of the group. You are now a toy for her pleasure, and you stick your tongue out to capture some of her essence. This is probably some form of heaven., you think, as you are lost in a world of pleasure, being used purely to get your marefriend and two sexy princesses to cum. Celestia decides she wants in on the fun, and swivels you around to where you are now sliding up and down her godly dick. 

It's all too much for the three of them, and they all start to slide their magic up and down even faster, at speeds that would rival a horny teenager. You almost start to get sick from the motion, but you aren't, just enjoying the ride. You're still hanging on for dear life, though. It gets faster, and faster, and even faster until the Princess of the Night is the first to break. 

"WE ARE CUMMING" she shouts, as her navy magic bursts out of her horn and the dam breaks. Spurts of cum fly out into the condom, the rubbery net catching all she has to offer. Some of it drips down and starts to leak on to you. It falls into your mouth, and to your surprise, it tastes almost like the Hayterade. Just thicker. Like an ice cream version of it. Twilight is the next to go, and you can hear her ropes of jizz fly and hit the condom, bulging it out even more. The tip starts to fall to the side of the triumvirate of flesh. Hers falls on you, too, and you are almost encased in semen like Han in carbonite. Her flavor is comforting, like warm milk before bedtime. You could almost fall asleep like this, until you are startled by what sounds like a cannon at your size. 

"FUUUUCK" Celestia screams through bared teeth, and her magic stops just as she unloads. Her output rivals a firehose. Ropes as thick as a magic marker and as pungent as a spray of air freshener, her cum rockets out as the other two princesses continue to cum. The blasts get so hard that the condom just can't take the viscosity and the volume anymore. The expanding balloon of spunk falls down on to the bed, and the second it touches the comforter, it explodes like a water balloon. It splashes back and coats the cocks with their own ejaculate, and they all continue to let loose, emptying their balls with every line. 

Now they are just shooting it in the air, and all of their heads are thrown back in pleasure, catching the droplets of falling jizz like snowflakes in the wintertime. But this was somehow whiter. Even the ceiling catches a few blasts. But most of it falls just on the center, and you are now in the middle of a jizz blizzard, the white stickiness coating you and gluing you to the flesh that you are between. Almost 30 seconds later, they all fall back, the opening of the condom's elastic giving out, and snapping. They all fall in 3 different directions, and you fall in the middle, a deep puddle of semen building up. You get up and kneel in this puddle like a kiddie pool, until you start to feel a bit funny. 

You feel like everything is expanding, and it is. Your arms start to get longer,  your torso and legs expand with muscle and fat, and your head suddenly feels a lot heavier. Your dick and balls grow back, having spurted their load when the royalty did, and they were back to their (new) regular size. You fall down onto your back, and you find yourself right next to the Princess of the Sun, her white fur and pink bra coated in her off-white juices, almost looking golden to match her magic color. She turns to you, still panting and breathing very heavily after the pleasure overtook her, and looks at you with her bright purple eyes. Your own eyes meet hers, and she wipes some cum off of your nose, and plants a kiss right on it, smiling at you as you get lost in her caring and exhausted gaze. You smile back.

"You sure know how to please a mare. Several, in fact." she eeks out between heavy breaths. "I know you'll be good to my favorite student. 

"Thank you, Princess."

"Please, call me Celestia. Even 'Tia' if you prefer."

"Thank you, Tia." you reply, feeling uncomfortable for a second, before it starts to sound comforting. Like you were part of the family now. 

"Hey, Twilight?" you ask, sitting up. 

"Yeah?" she says, also sitting up, wiping cum off of her face.

"Can I pick the pizza and the movie tonight?"

"So you think you deserve to pick both now?"

"I do. "

"Sure. But no pineapple."

You chuckle at the caveat. "Deal. Now let's go shower up and clean up this mess." you touch your nose with the tip of your finger, and Twilight and Celestia do the same nonchalantly. All 3 of you stare at Luna, who is just looking at you all with a confused look. Your fingers stay on noses until you can almost hear the gears turning in her head as she starts to get it. 

"Ugh, I guess if I have to clean up." she says, in a fake-dejected tone. 

"I'll let you have first slice." you say.

"Who gave you that authority?," Twilight starts, "Are you the Prince of Pizza or something?"

You look at Celestia quick, "We should make that a thing."

The three Princesses laugh at your request as you all hop off of the bed and walk to the shower. You weren't even thinking about what Twilight had planned for your last night, but she was smirking internally as she knew what was in store for the finale.
> 7. The Final Night.
> --------------------------------------------------------------------------

You awoke on the giant bed in Twilight's bedroom, a couple pizza boxes were on the floor on the side of the bed. Your head was resting against actual pillows this time, as it was just you and Twilight sleeping on the bed. She was next to you, conked out and slightly snoring. You noticed most ponies snored when they slept, probably something to do with their faces and teeth. You grabbed your phone from the bedside table and noticed it was about 9 in the morning. Thankfully, both you and Twilight were off today, and could sleep in. But you both liked getting out of bed before 11, since you usually had stuff like chores or were planning something fun for that day. But you don't know what she had planned for today, since it was finally the last day of your Anniversary Sex-travaganza, as you had billed it in your head. You boop your significant other on the nose as you stretch and throw the covers off. 

"Whuh?" Twilight groans, her eyes fluttering awake as she feels the cool breeze on her arms, her pajama pants and t-shirt covering her curvy purple frame. 

"It's after 9, egghead!" you say as you chest pass a fluffy pillow at her face. She catches it with her magic and hurls it back, and you're not sharp enough with your magic to catch it, so a *paff* muffles your voice as the pillow makes contact with your surprised face. It didn't do much to quell your morning mirth, you were actually well-rested, fed, and not covered in semen for the first night in a while, at a normal size with all of your body parts intact. You were feeling like a million bucks, even with the pillow assault.

"Only Dash can call me that, dumbass." She says, clearly pleased with her headshot. She got out of bed and walked over to you, kissing you on the nose. You caught a peek of her cleavage as she bent over. Still nice as always.

"Speaking of her, why haven't I seen your friends at all this week? You didn't think to involve them on all of this shit?"

"Eh, just hasn't come up. I wanted you to get the full experience with me and the other princesses before we branched out that much."

"What about Cadence? I haven't seen her this week. Did she not want to get involved? You know, Princess of Love and all."

"She had Crystal Empire stuff to do. I think she's coming back tonight, not sure though. All I know is that we're going to be late for breakfast.  So let's get dressed and head down."

"K!" you say, as you slip off your pajama pants and throw on some basketball shorts and a hoodie. Twilight casts a quick spell to conceal her downstairs bulge and throws on similar shorts and a t-shirt. You walk down to the dining room in the castle, and you see a bounty of food waits for you. Scrambled eggs, tofu bacon, french toast, waffles, and what appeared to be mimosas. And that wasn't even all of it.

"Just a little token of my appreciation for putting up with my bullshit." she says, giggling as your jaw is on the floor.

You see Celestia, Luna, and Cadence already sitting down, sipping their mimosas while conversing.

"Come on, we're waiting for you!" Cadence says. "We flew back all the way for this, and boy are my wings tired!"

You scoff at the dumb joke and speed walk over to the table, sitting down and placing a napkin on your lap before a glass of champagne is poured in front of you and mixed with the orange juice.

"Where's Shiny?" Twilight says, already grabbing a few strips of the bacon.

"He's prepping decorations and signing off on deliveries for the party tomorrow." Cadence says, in between bites of eggs.

"Tomorrow?" you say. "I thought it was today."

"No, silly." Twilight says, as she squirts hot sauce on some hashbrowns, "We've got one more day of fun to go. It won't be until later tonight so that you have a chance to let this settle."

"Any hints about what awaits me?" you ask.

"Just be in the conference room at 6. Wear only a robe."

Your eyebrows perk up as you process the requirements. You decide to react accordingly when it happens and dive back in to your breakfast. The rest of it goes smoothly as you chat with the princesses and catch up on what you and Twilight missed in your week of debauchery, and what Cadence and "Shiny" have been up to. It was all well and good, you all had a few mimosas (that had exponentially decreasing amounts of orange juice, you might add), and were getting a nice buzz going before Celestia and Luna realized they had real things to do. You all said your "see ya later's", Cadence and Twilight left to go meet with Shining Armor, and you went back up to your bedroom to dick around on your phone or computer or whatever and wait for tonight while you let your buzz wear off and your feast settle. 

As it got closer to 6 o'clock, you went to your armoire to get your robe, when you realized you didn't even have a robe! Then a knock on your door came, and you opened it to find a plain brown paper gift bag sitting outside it with a note attached that simply said "<3 - Twi". You shut the door and place it on the bed. You dump the contents out and arrange them in a grid so you can see what was there. A note, a small assortment of bottles that look like the sample ones from liquor stores, a bottle of water, and what do you know, a fluffy robe. It was the same dark amber color as your magic was, and it had your first initial lovingly sewn on there. A small "CB" logo adorned the tag, so you know Rarity made this. She was pretty good at that. There were a total of 4 small bottles. Two pink, one was blue, and one was that same amber color. The amber one had a different cap, one that looked like it held an eyedropper in it. They didn't have labels, so you decided to read the note to see. It was written in a dark purple pen (of course), and was on basic cream card stock. Twilight was always one for function over fashion. It read:

To the best boyfriend ever (aka You!):
I want to thank you from the bottom of my heart for putting up with all of the events of this week, and for trusting me at every step of the way. From switching your sex, to the odd body modifications, to even turning you into my cum! You barely hesitated because you knew in your heart that I would keep you safe. You're going to have to trust me for one more night, and then this hectic week will have come to a finish. I know that whenever we would meet, my dear friends always had their eyes on you (can't blame em), and you had your eyes on them. While I'm glad you never acted on impulses, I'm giving you the opportunity tonight to do just that. I won't be there for any of the events in the conference room tonight, so it will be just you six. After the night there is over, come see me up here, and we can end it the right way. Take the pink and blue potions down there with you, the girls know what to do with them. I love you.

-Princess Twilight Sparkle

There was a small glittery sticker of her cutie mark next to it. It was one of those puffy stickers. You know how much she liked those.

You slip off your other clothes and slide on the robe. It was super soft and fluffy. You tied the rope around your midsection and place the 3 bottles in your robe, placing the amber bottle on the nightstand next to the bed. You walk down to the conference room, which was just adjacent to the throne room where the Cutie Map was. This room had better, padded chairs and a way smaller table when they didn't need the map. Which was more often than not. The door was shut, and so you knock a few times to see if they're ready. 

"You can come in, only once you've taken the blue potion." you hear a voice say through the door. You twist the cap off of the blue potion and gulp it down in one shot. Blueberries, you think. Little bit of an alcoholic taste, too. "Show me the bottle." the voice says, as you open the door slightly. A white hand shoots out with a palm facing you, and you give the bottle to the "mysterious" pony. "Good." she says, as she opens the door the whole way after examining the bottle. 

"Hello, darling. It's so nice of you to join me here." Rarity says, wearing a very similar robe to yours, hers in a purple that matches the color of her mane and tail. It was very loosely worn, almost sliding off of her shoulders. She stood at 6'5", a little bit taller than you. Her robe was, however, a lot shorter than yours. While yours came down to almost your knee, hers seemed to be halfway up the thigh. It wasn't tightly tied like yours was. Her cleavage was pretty nice, had to be a large D cup. Big, but still petite by her frame. She was wearing a slight purple gloss on her lips. 

"I thought the rest of the girls would be here?" you said, as the room was empty aside from the fashionista and yourself. 

"Oh, they'll be here, but I thought we could get the party started. I've seen those eyes you gave me when you first got here. Even a year into your relationship your gaze seemed to wander over here. It's a good thing we both know our limits, because less restrained ponies might have jumped at each other a long time ago. I'm going to give you something you've thought about for some time."

She sauntered over to you, hips swaying like a porno. She walks up close to you, and grabs your behind as she pulls up close to you. At this point, you think you know why she has her robe on loosely. She moves her head towards yours, and comes together in a kiss. She runs her lips over yours as you swap saliva like it was a cheesy scene from a movie. She starts to rub against your chest, flicking your nipples lightly as your chest felt like it just got a bit of a static shock.

"Before the fun really starts, I'm going to need you to get me ready. This robe is very restraining. Could you be a dear and take it off for me?"

You oblige, undoing the very loose bow she had tied on the front. As you untied it and slid it down her shoulders, you confirmed your earlier beliefs of why her robe was loose. A foot-long, lighter black horsecock. It was almost as wide as a tall boy can, already leaking some precum. It was being produced by her heavy testicles, about the size of a baseball. They were a darker light black. Like a charcoal grey. They were tucked in to what appeared to be a specially made pair of panties that hugged the duo tightly to her body.  Darker than her mane, even. It came flopping down, bouncing back up to a 75 degree angle with her body, like most erect penises do. The bead of precum on her tip was sliding down, and dripped on to the carpeted floor, leaving a small damp dot. 

"How...?" you stammer out, taking in the sight of her cock, which you absolutely know she didn't have before.

"You know Twilight takes care of her friends, darling."

"Well now, we can't be wasting any of that, now can we? Why don't you clean me up a bit before the fun really starts." While she is speaking, she lightly pushes down on both of your shoulders, coaxing you to kneel down and go head to head with her lower head. You slide the band of her panties down and slid them to her ankles, exposing the black flesh. You caught a whiff of what was apparently her musk, but it smelled more like a fine perfume. Her dick must be new if it hasn't built up anything serious.  You stare back at her package, bobbing and dripping ever so slightly with her heartbeat. You lean in and breathe hot air on her slightly squirming testicles, which causes her to shudder a bit. You plant a kiss on each of them before taking the sack in one hand, and gripping the base of her shaft in the other. You are now face to face with her dripping marecock tip, and you plant a wet kiss on the top, smearing the precum all over your lips, coating her urethra and head in your saliva. You hear a little squeak out of the fashionista, as it's clear she hasn't experienced this before.

You take the whole head in your mouth, wondering how it's fitting with the girth. You chalk that up to the potion you consumed before walking in. You run your tongue around her flare, and work your way around the tip. You start to work your way down the dick, taking it centimeter by centimeter. It was pretty big, so you had to make sure you didn't bite off more than you could chew at the moment. Your tongue runs over the vein on the underside of her dick, making sure to move back and forth across it like a guitar string. You feel her convulse a bit above you, clearly enjoying the worship. You thoroughly coated the top half of her dick in a mixture of your saliva and her pre, which you thought tasted a bit sweet...like a marshmallow? What was it with ponies and jizz flavors?

All of  a sudden, you are pushed back off of her dick as you look up to see Rarity panting, her chest heaving. 

"Not yet. There's something else I want to do. Strip and get on to the table, if you please."

She walks towards her phone and checks it quick, tapping out something as you disrobe, putting both yours and hers on a coat rack near the door. You sit on the edge of the table. It wasn't very wide, about as wide as the desk in your office. It was usually for more events with just 3 or 4 of the regular 6. You hop on the table, letting your legs dangle off of the edge, dick hard as diamonds. 

"Are the others going to be here soon?" you ask.

"I'm afraid not," she says, setting her phone on an end table and walking over to you, "So it looks like it's just me and you. All. Alone." she says, progressively getting louder, as if giving a signal.

"Not so fast!" you hear from outside the room, as the door swings open, and a blue pegasus is outside with a smirk on her face, and not a shred of clothing on her body. Rainbow Dash glided into the room, light as can be. After her, followed the rest of the Elements of Harmony. First Rainbow, then Applejack, then Fluttershy, and finally Pinkie Pie. The four of them traipsed in, all naked as the day they were born, but all with a little bit extra. You go down the line, making a list of attributes of each pony standing in front of you. 

Rainbow: Thin, boy-ish frame. B-cup breasts, a navy dick just a bit smaller than yours (about 10 inches), decent girth, and egg-sized balls, colored a deeper blue along with her sheath.

Applejack: About the same height as Rarity, thicc thighs and ass (must be the farm work), a 6-pack, slightly bulging biceps. D-Cup breasts and a 12 inch, burnt orange horsecock with baseball-sized testicles that were just a bit darker orange.

Fluttershy: About your height, ass and thighs about as thick as Applejack's, and she had a 13 inch dick with avocado sized nuts. Her breasts were huge, probably like GG cups if you had to guess. Hers were even bigger than Celestia's. Her dick was a calm yellow like her, with a slightly darker yellow for her balls and sheath. Kind of like when the yellow marker gets tainted with the black marker. 

Pinkie: She's the only one you could really call "fat", which as a baker who had a thing for sweets, it was obvious. She was a few inches taller than you. Big tits, EE cups probably, and an 11 inch dick. Normal girth. But her balls had to be the size of softballs, easily. They hung very low. Her dick was bright pink with a magenta sheath and sack, in the same coloring trope as the other ponies of this world.

As soon as your character-sheet style analysis had finished, Applejack was the first to speak up. 

"We hear that it's a special occasion for the two of you lovebirds, and so we're trying to see what all the fuss is about." her twang was subtle in her toned-down voice, putting on her best "innocent girl" act for you. "We hear you're pretty good in the sack, and wanted to find out ourselves. So why don't you lay back on that table and let us do all of the work."

Your boner somehow got even harder, from both arousal and a bit of fear. Apparently, you didn't lay back quick enough, out of fear or something, and Rarity came over with a bottle of lube in her hand, and squirted some onto yours. Your chest still felt a bit tingly, and you weren't sure if it was the arousal, your heartbeat, or your mind playing tricks on you.

"Lube me up, big boy. I need to feel what Twilight feels."

You rub the lube between your hands as you coat her throbbing horsecock in the slimy fluid, knowing full well where that dick is going. A small bead of pre leaks out and mixes with the lube, serving to slick up the meat further. She squeezes a bit of the lubricant on her hand before tossing the bottle to nowhere in particular. She slathers it all over your chest, making sure to get the area between your pecs. 

"What was that for?" you ask, chest still tingling and the cold lube not helping the feeling.

"Give it a few seconds and you'll understand."

As you lay back on the table, your chest starts to tingle even more, and you see it expand a little.

"Rarity, was there poison joke in the potion Twilight gave me?"

"Poison joke? Nooooooo...nothing like that." she says with a stupid grin on her face. 

"Good to know." you reply dryly, "Are the other two potions anything weird?"

"No, those are just recovery potions. Those are fine."

Your chest begins to expand, as the flesh balloons out. The sound of them expanding is like filling a water balloon with whole milk. Not thick, but certainly not as thin as water. They keep expanding, and start to droop a bit. They end at about a DD cup. A bit smaller than Rarity's and Applejack's. You lay down on the table now, not really being able to see much over the mountain peaks. You see Rarity's head (the one on her neck) smirk as you hear the sound of her "spreading" the lube out even more. Your view of Rarity is soon blocked by a large orange mass. Applejack suddenly climbs over you, and is soon straddling your body, almost sitting on your dick. You soon feel the presence of the other 3. 

While you looked around your head and saw the other 3, Applejack wasted no time and knelt down quickly, and you entered her tight pussy. Her dick flopped on to your chest, acting like a grocery stick between your new breasts. Your mouth went agape and you gasped out and threw your head back in surprise. It hung over the end of the desk, which basically all but sent an invitation to the pink party pony by your head, who shoved her thick horse dick into your mouth, getting the tip in just to start. And as she put her dick in your mouth, you felt the immediate pressure of Rarity's well-lubed dick start to prod at your behind. You grimace as she slides her tip in, opening your back passage ever so slightly with a slight pop.

You hear an "oh boy!" as Pinkie is bouncing to your right, erect dick flopping next to your hand, clearly ready for your touch. You swab your hand over the tip to lubricate it, and you take the marecock in your grasp. You look up at Pinkie and she nods and looks the other direction, signaling you to look at the shy yellow mare to your left, also in a similar situation. You do the same to her as you did to Pinkie, and take a hold of her thick rod. 

"Everybody ready?" says Rarity, to a chorus of "Yup"s and a solo "Oh Yeah!" from Rainbow. You take your hand off of Pinkie's dick to shoot Rarity a thumbs-up, as your mouth is somewhat occupied, and replace it, the sticky pre coating your hand. Rarity thrusts in, signaling the start of the gangbang. Rainbow does the same, sliding in to her medial ring, a bulge in your throat already forming. You start to pump at the twin dicks in your hands as Pinkie bucks with it, and Fluttershy lets you do the work as her thick cock quivers in your sticky palm. They're all somewhat rusty with their temporary endowments, but you have a feeling that they use this spell often. Rarity is already completely lost in her movements, as you already start to feel warm pre enter your backside. Her thrusts keep you bouncing up and down, which causes helps out Dash, who is grabbing your head with both hands, her thick cyan dick sliding in and out, getting slick with her pre-cum, which almost tastes like blue raspberry. You chalk that up to the weird thing with pony fluid flavors and just enjoy it.

You can barely handle the two dicks in your body to be able to focus on the pussy lips wrapped around your own dick, as Applejack grinds up and down and back and forth, moving your dick in her vagina like a joystick, touching all parts of her insides and causing you to spasm and leak some of your own precum. Applejack's own pre-ejaculate is leaking between your supple tits, every thrust of yours into her causing her to slide her cock between them. You haven't been able to get a taste, but you have a pretty good idea of what it is. You're also so enamored with the penetration that you can barely remember to jerk off the two ponies to your sides. You are doing okay with Fluttershy, as your left hand usually jerks a dick anyway, but your right hand is a bit slow. Fortunately, Pinkie noticed and is now grabbing your hand with hers and is fucking your hand, wet with silvery precum.

You hear breaths getting ragged from all participants of the fucking, including yours. Dash is fucking your face with a certain intensity that leaves you short of breath, taking small ones as she pulls back, her balls slapping against your forehead as her rod goes down your throat. Rarity is doing the opposite, as she does not want to be the first to burst. Her thrusts are thought-out and intense. She pulls almost all the way out, leaving only her flare, and goes all the way in, which would probably split open your insides were it not for the potion. Her thrusts push you back onto Dash's dick, which her thrusts send you back to Rarity's dick. It's a viciously arousing cycle.

Fluttershy is now gasping and is thrusting the hardest you've felt her thrust, and you brace yourself for her orgasm. 

"Eep!" she cutely squeaks, releasing her few ropes of jizz. The first one hits you square on the face and you shift your hand down ever so slightly to get it away, as the next shots hit you directly on your boobs. 

Butterscotch, you think. You're just glad it wasn't banana. The sensation of the hot cum on your tits is just what is needed to set you off, as you cum hard into Applejack's pussy. You moan and cry out through the dick in your mouth, the vibrations from which cause Dash to explode in your mouth. She was so deep that most of went straight into your stomach, bulging it out just a bit. She pulls out so you don't pass out from lack of air, and paints your face, leaving thick globs behind around your mouth and chin. As you finished cumming into Applejack, the feeling of being filled set her off, as she came simultaneously from her vagina, splashing the base of your dick, and from her cock, trapped between your pillowy breasts. You felt a hot layer of sperm cover them, as a shot made its way onto your face and into your mouth. 

Apples. Duh. you think, savoring the tart and sweet flavor. Your right hand was still moving along the pink cock of Pinkie, who took one hand off of hers and craned your head towards her dick, and blasted you with a shot of hot sperm, like a sexual Super Soaker. You were not surprised by the cotton candy flavor, as it melded with the blue raspberry and apple flavors to create an odd sensation that reminded you of the suicide slushies you would get at the convenience store as a kid. But those thoughts were interrupted as more jets hit your face and a satisfied "ahh" came from the pegasus above you. You kissed the tip of the cock as she finished, the opening a mere inches from your face. But your kiss was suddenly escalated as Rarity pounded hard one last time as her balls slapped your ass so hard and she locked in. You screamed out and Rainbow's tip was suddenly in your mouth like a pacifier as the white unicorn piped your rear full of her thick cum, causing your already bulging belly to balloon even more. You suckled on Dash's tip to help clean it off as the floodgates were slowly draining into your gut.

"That was sure somethin'!" Applejack said as she lifted herself off of you, a torrent of your own jizz falling back on your groin.

"Yeah, that was amazing!" Fluttershy sort-of-yelled.

"Twilight is definitely a lucky girl to have you!" Pinkie said, "but now we have to go and help set up for the party!"

One by one, the 5 cum and sweat-stained ponies came and kissed you on the cheek or forehead, each finding a spot with another participants' flavor on it. 

"So you're just going to leave me here?" you ask, blinded by the cum, as you wipe it out of your eyes. 

"Not to worry, darling. We're going to let you savor this and someone will be in to check on you shortly. Ta-ta!"

Rarity slowly closes the door as you are left to get your heart rate back to resting as you marinate in the pony spunk of all kinds of flavors. You finally gain the strength to sit up as your belly juts out in front of you, your tits sagging onto it. You feel that this is the closest you will be to being a pregnant woman, and the warmth is sort of comforting. 

You hear a knock on the door.

"Come in" you shout, now trying to wipe all of the jizz off of your face.

The door opens and a pink alicorn walks through, wearing just a bathrobe like Rarity was. She must have outfit the entire royalty with them. They were nice robes, after all. She spies your robe and grabs a blue potion out of the pocket and walks over to you. 

"Someone just had a good time, didn't they?" she asks, as she eyes up your bloated and sticky frame.

"You could say that. Are you in here to check on me?" You ask, knowing the answer.

"You could say that." she replies, mimicking your tone, "Now drink this." 

You unscrew the top of the bottle and take a swig. It's a little alcoholic, but not too much so. 

"Now hold still." A bright blue flash comes out of her horn is gone as quickly as it appeared. You suddenly feel a bit lighter. You put a hand up to your face and feel the lack of genetic material coating it. Your rack, stomach, and ass are also clear, as is the carpet and table. You start to feel a tingle in your chest and stomach, and notice that they're both starting to shrink. Your stomach goes back to normal, feeling fairly empty, but not painfully so. Your breasts are almost gone, now down to a B-Cup.

"So, is this all you were sent to do? Get rid of my gut and clean me up?"

"Not just that. I'm here to help you relax a bit after that, it can be stressful. I'm here to relieve some tension in a more traditional sense."

She snaps her fingers, and a foam pad that looks like a thick yoga mat materializes on the table behind you. "Now lie on your stomach and close your eyes. I'm just going to work on your back a little."

You reluctantly roll onto the mat and on to your stomach, resting your head on the pillow with the face hole that also materialized with the mat. She snaps her fingers again and it suddenly smells like lavender and mint. It calms you down considerably as she harshly digs her elbow into your shoulder blade, which hurts at first, but soothes right after. 

"Oww-ohhhhhh...." you let out, a knot in your back suddenly dissolving. "Didn't know you were a massage therapist."

"Well, Love comes in many forms. I'm not the Princess of Sex, it just seems like that. Love can involve knowing your partner's sensitive areas and helping to relieve stress and tension. I'll teach you to work similar spots with Twilight, especially when she needs to be preened."

She continues with her massage, getting your shoulder blades, shoulders, lower back, and starts moving down towards your hamstrings and calves. Every push sends a burst of bliss into your body, all of the tension you didn't even know existed in your body melted away. You almost felt like you couldn't even move. You were so wrapped up in your massage, that unknown to you, the two other main princesses walked into the room and were conversing while sitting down. By this time you felt a cool substance on your feet as she had started to rub them. 

"This will be the final part of my massage, the most tension in your body lies in the legs, especially the feet. This will help keep them soft, while making sure they don't start giving you problems."

"Enjoying your break, my little human?" you heard, the voice coming from the white alicorn.

"Celestia, when did you get here?" you ask, voice muffled from the face pillow.

"About 10 minutes ago. We wanted to see how you were feeling."

You look up to gaze at the voluptuous princess, "Would it also have anything to do with the fact that both you and your sister are naked, instead of wearing a bathrobe like Cadence is?"

"Took you long enough to notice. And since we're pointing out things you're not noticing, it looks like Cadence isn't wearing a bathrobe anymore."

You turn onto your butt and sit up, noticing that Cadence has ditched her robe and is now starting to get an erection, her magenta phallus bobbing up with every breath she takes.

"So round 2, eh?" you say, sitting up, bones cracking back into place after the massage. 

"You catch on quick," Luna says, standing up in unison with her sister, "Now, who gets the pleasure of penetrating your behind? Me, or my beloved sister?"

"What about Cadence?" You say, thinking about which you want in your ass.

"She wants the feet." Celestia says. "That's kind of her thing."

"So I'm guessing that the "massage oil" for my feet was something else?" you ask, making air quotes.

"Duh." says the pink princess.

"I guess I'll take Luna. I'd rather have my throat stretched more than my ass."

"That was actually the preferred outcome," the mare of the night says, "I've wanted a piece of that for a while now." she growls sensually as her dick rises.

You assume the same position as you did with the 5 that were previously occupying your body, but with a few modifications. The three Princesses have moved into position, Luna at your rear with Cadence behind her, and Celestia at your head, her monstrous dick erect above your face, dripping on to your still swollen chest.

"Shouldn't we get me, uh, 'prepped', first?" you say, clearly not wanting the two princess penises to go in dry. 

"Oh, we're always lubed. Special spell. But for you, dear sir, I will oblige." Luna summons the bottle Cadence was using and smears it on her dick and your hole, and you wince a bit as she pokes her finger in to swab your insides.'

"Good?" 

You nod. 

"Well, then. Let the copulation COMMENCE!" she shouts, as her tip penetrates your somehow tight hole. You exhale sharply through your teeth. Celestia flashes her horn and you feel a burst of magic go through your mouth and into your throat.

"This is so you can breathe and take my massive rod." she says, pulling her dick back so the tip is just against your lips. Right before she pushes in, you feel two hands grip your slick feet and push them together, being the metaphorical bread for the dick sandwich with Cadence's meat occupying the middle. You curl your toes around the warm flesh, hoping to bring her more pleasure. You try and move them up and down, but your perspective is kind of off so she starts to move them for you.  She moans a bit, clearly enjoying the sensation. You don't get much time to react to her reaction before the marble column known as Celestia's marecock slides into your mouth, the leaky tip already stretching your jaw.

Fuck, she's huge! you think, eyes already watering. 

Thanks, you hear her think back. You now wonder when she can read your mind like that. Only during sex and stuff like that. You sigh in relief, only to be interrupted by Luna slamming her thick stallionhood into your hole. 

"Are you two," she starts between thrusts, "just going to think back and forth or are you gonna fuck?"

Celestia knows both your answers and pushes in further, putting 3 more inches of dick into your mouth, nearly touching your uvula. You choke slightly from the invasion, but welcome the sensation as you grab both sides of the table so you don't fall off. Luna is hard at work, pumping in and out of your behind, leaking her hot pre all inside of you. You can feel her medial ring just hit your asshole as she wants to go further. Cadence is lost in your feet, pumping away as her rigid cock slides across your soft and supple soles. You tried to keep them moisturized, especially since you went sock and shoeless in the castle most of the time. You feel her balls slap against your heels as you feel Luna's voluminous and dense sack slap against your butt, while Celestia's softball-sized nads hit all over your face, bathing your nose in her musk. The male scent, combined with the scent of clean towels drives you insane and drives you to want more of the aroma. 

"Fuck, your feet are good. Shining's are nice, but yours are just so soft!" Cadence cries out, mesmerized by the footjob. 

Celestia is now just using your throat as a glorified fleshlight, pumping in and out at increasing speeds. Her medial ring is touching your lips as there is now an obscene bulge in your throat. Her precum does a great job at slicking up her entry as you choke out of habit, but not out of necessity anymore. Her spell made it a-OK for you to take her impossibly large shaft. 

Everybody's breaths are getting ragged now as they've been using you like a sex toy for just about 10 minutes. It's a symphony of sweat, precum, and musk as all 3 princesses look ready to burst at any time. Celestia is now going all the way in and halfway out with every thrust. You probably have a concussion from her balls hitting your head so many times, but it's worth it. Her frosting-like semen (in texture and flavor) is pumping into you, and leaking out as a bulge in your stomach has already started to form. Luna is now flaring up, and she looks near. Cadence is also leaking, her hands slipping from your feet every so often as you try and help her out. 

To your surprise, the mare of the sun is first to go, and she grabs your head and locks it to the base of her cock, her balls smothering you as they gurgle. Her flare has reached down into your esophagus and is now shooting out her hot load at a high velocity, quickly filling your stomach with the heavy batter. Your belly starts to expand like a water balloon as she locks in place, pumping to get it all out.

Luna is next, and she goes balls deep on her last thrust, holding your butt close to her hips, draining her heavy testicles, rope by rope. Her cum joins her sisters as it expands your belly, now looking like you swallowed a beach ball whole, with even more to cum.

Cadence comes last, crying out as she pumps her last pump and launches a rope over Luna and on to your chest. She removes her hands from your feet and puts them together as she aims her dick at your feet, volley after volley of sticky semen coating the glistening, puffy soles of your feet like a glazed donut. Your body becomes consumed by the whiteness as your unattended dick shoots its load, splattering the chest of Luna, and then raining it down on yourself.

After a solid 30 seconds of synchronized jizzing, Celestia and Luna pull out simultaneously. Celestia and Luna are both spent, nothing dripping out of their cocks or your body as magical seals are placed on your holes to make sure you keep their whole loads in your belly. You look like you're pregnant with two sets of octuplets, and those octuplets are all having twins. Cadence walks around to your face, still breathing hard as she thinks to you, now clean. You grab her still throbbing maremeat like a baby bottle as you suckle the last few ounces of cum out of her tip. This stuff tasted like strawberries and cream. Interesting, but fitting. 

Celestia summons chairs for the alicorns in the room, and they all unceremoniously plop down on to them, all four of you sighing as the bell sounds for this round. You try and wrap your arms around your belly, but you can't even manage to get halfway up. You're so full, you feel like you might explode. 

"Holy shit." you say, breaking the tension with the first words said in a while.

"Yup."

"Yeah."

"Verily."

"We should do that more often." you say, patting your stomach, sounding like a drum.

"I don't know if I can ever walk again." Luna says, reeling from her anal adventure.

"Well someone is going to have to, I can't live with this gut forever. What time is it, anyway?"

Cadence summons the courage to get up, stumbling from the sensations. She grabs the bottle and your phone, handing you your phone in one hand and uncorking the bottle. 

"9:40", she says, "You've still got a bit of time before you have to be upstairs, but we should make you presentable. Now open up." You open your mouth as she pours the pink potion into your mouth, as you feel your energy already come back, and your gut and chest start to deflate. Your ass seems to get a bit thicker, probably some kind of balancing thing from all of the cum. Cadence's horn and hand flash as you feel the cum leave your body, and your breath returns. While that part is getting back to normal, Celestia floats you over to a chair and summons a floating sink to clean and tame your messy hair, and Luna throws a quick dry-clean spell on your robe and moves it toward you, putting itself on as Celestia makes you pretty again. Cadence zaps in some bottles of water as you talk and discuss the night for the next few minutes as you all take a break to relax before you have to head upstairs.

"Alright, 9:55. I should head up. I don't want to upset Twi. Catch you all tomorrow at some point, probably."

"Of course," Celestia says, "I'm glad we got to do this. Maybe we'll have Twilight join us next time." You smirk as she says that, opening the door and leaving the three princesses to devolve into schoolyard gossip about the sex.

You check your phone as you hop in the castle elevator, seeing texts from the rest of the "mane 6" gang as well as the princesses. Lots of well-wishes, lots of suggestive emojis, mainly the eggplant and pointing fingers next to the "OK" sign. Mainly from Dash and Pinkie. And one pops up as you exit the elevator, and it's a picture of Twilight laying down on her stomach, feet up and naked with a couple of peach emojis attached. You don't even need to check the sender of that one, it's fairly obvious. 

The door to your bedroom is locked, and you knock to gain access. Twilight magics the door open, and as you walk in, you see a needle fall on to a record next to the door.

" I've been really tryin'  baby. Tryin to hold back this feeling for so long... " the male voice starts out. You check the record sleeve and the name "Marvin Haye" is plastered on the front with a brown stallion sporting a beard. You start to think now how much of a parallel there is between your two worlds. You shake it off as you see the purple alicorn mare saunters out of the bathroom, butt naked, as she turns down the music a little for you to take in her form. Just as beautiful as ever, but missing a key feature. She walks up, sans male genitalia, and smushes her chest against yours as you give each other a quick kiss.

"Tonight," she says, in between lip-locking, "it's all for you. No tricks, no swaps, no transformations. Just you, me, and the bed. Now there's just one thing left to do." You walk over to the bedside table, where a silver tray with two vials are on it. One is the amber one from when you first got in this evening, but there was a new one next to it, with the same eyedropper top. The fluid inside this one was a bright purple. "You see, even after our little melding 'experiment' earlier this week that left you with some attributes of mine, our genes aren't compatible. So we've never had the need for condoms unless you didn't want to be inflated, or we wanted to keep the cum for testing or whatever. But with this, it allows us to be more 'alike' each other."

"Twilight, are you saying, what I think you're saying? Do...you...want to h-"

"Yes." she cuts you off, obviously knowing the end of that sentence. "After spending this last week together in the most intimate of ways, combined with the previous years of being together, I would...like to," she exhales slowly and calmly between the words, "bear our children." 

You knew that was coming, but it didn't make it any less shocking to hear. "I have so many questions. How are you going to accomplish this? Will I be turning into a pony?  Will our child have fur, a horn and wings, or hooves?"

"Those are a lot of questions. First of all, you won't be turning into a pony, either temporarily or permanently. Those two little potions contain little bits of our magic essence, and it will bond us. You'll be getting a little pony DNA, I'll be getting some human DNA. I'm not going to get human ears or whatever, you're not going to grow a tail or any appendages. At most, you'll get a little more muscular, and I may get a bit, I dunno, shorter, I don't know. I'm an alicorn, we're basically unalterable. As for the appearance of the child, we just don't know. This kind of thing has never been done before. You're the first human to romance royalty in this manner. The others have simply just left, or were cast away, or died of old age. There was one a few thousand years ago that kept saying stuff like ">no hooves", even though hooves on a pony are rarer than being a naturally-born futanari, which are like 1 in every 200,000 children. And any female humans were willingly turned into ponies when they wanted to conceive, since we didn't have the technology. So there is just no precedent for this sort of thing. All I know is that it will be ours."

You got lost in "ours", and Twilight had to snap you out of it. "Now come on, lets not debate this too much. You and I both know we were going to, it was just a matter of when." She grabs your hand and walks you over to the table, where she hands you the vial with the amber liquid. On the side was a label that said "His", and you could see that Twilight's said "Hers". "Now withdraw one dropper full of the liquid and don't squeeze it out just yet. I'll do the same with mine." You now realized where this was going, and withdrew the amber liquid. It was the color of a nice apple cider, but smelled a bit like it was alcoholic. Hers was very "grape pop"-esque. "Now squeeze yours into mine, and I'll put mine into yours. Then we shake them up and drink." You squeeze simultaneously, combining the two liquids. They stay separated for the moment, but that's before you both put the caps back on and shake. Instead of becoming a light-brown like you thought they would, they instead swirl together like they were solid. "Down the hatch!" she says, as you two cross your drinking arms and down the vials, each in one go. It tasted like you mixed grape pop with lemonade with a little alcoholic twist. So not bad at all.

You immediately felt the effect of the potion, your body feeling a little bit denser due to the added muscle mass. You suddenly felt yourself get a little taller, you now were just looking right at Twilight's muzzle, which put you around 6'5" or 6'6". She didn't really look any different, since she was an alicorn and all. "Ooh, looks like it did a bit more! Guess we're just about equal now, huh?" You agreed, enjoying the bit of extra height, It would be less of a reach to kiss or whatever now, so that was pretty cool. While you were taking in your height, you failed to notice your own burgeoning erection as your shaft comes slipping out of its sheath. "Why don't we settle down a bit, hmm?"

"That sounds lovely." you say, as you move in to kiss her, going all in on this one. You grab her face with both hands and mash your lips on her snout as her eyes close and her arms drop to her sides as she takes in the newfound strength and force of her lover.  You pull off and look into her eyes, the purple iris shimmering as she looks back at you dumbfounded. You grab her and hoist her over your shoulder, putting her into a fireman's carry, and rolling her on the bed as she recovers from the sudden smooch. You take off your robe and throw it across the room onto the chair next to your bed.

"Hold on. Rarity made those especially for us, and she would hate to see that just thrown on the ground like that." Twilight says as she magics the robe onto the hook on the bathroom door. You shake your head but slowly turn it into a nod of agreement as Rarity would be the kind to do that. You slide on to the bed, as Twilight makes a pillow barrier on the headboard as she prepares herself. You lean over her on your knees, and grab hers as you slowly move her legs apart.  Her vulva lips were a little puffy and her labia was a little shiny; she was definitely ready to go. 

"You know," you start. "This position is almost identical to the one we were in earlier this week, just reversed. Back when having my dick turned into a vagina was the weirdest thing that had ever happened to me. But now it seems like that was just as common as doggy-style. And you never made me feel unsafe throughout the whole thing."

"You know I'd never hurt you." Twilight responds, "And all of these experiences told me that you trusted me, so I think it's time I return the favor and trUUUUU-ohhhhhhh....."

You interrupt her as your tongue slides across her outer lips, teasing them ever so slightly. Having a vagina had really helped you learn how to please one even better, and it was apparent with her moans. You go up and down the outer regions before tucking the tip in to her inner lips, before moving around in little circles. You swipe up and hit her little button and she gasps as her knees buckle and collide above your back. She starts leaking a bit more fluid, but you want her orgasm to come from your thrusts, not your tongue. You hear her panting as you get up after a little bit more oral ministration. "Ass. Are  you gonna let me cum or not?" she says, gasping for air.

"Oh I'll let you cum. But it's gonna be from my little friend here, he's really excited to meet you." you say in a cheesy porn voice before magically summoning a bottle of lube. It's nice to be able to use it on yourself this time. You squirt a little on your fingers and probe Twilight's insides as she shivers from the not cold but room temp fluid. You squirt more on your hand and lube up your dick as you get it prepped the old-fashioned way.  "Are you ready?"

"As I'll ever be."

You push your flat tip up against her opening and slowly push in, both of you breathing in through your teeth as you feel the sensations of the initial penetration as the tip fully slides in, a slish coming out as the flesh morphs to the shape of your dick. 

"I'm going in." you say, as you slide in even more. You slowly go until you hit the medial ring, and it's one of the tightest things you've ever felt. 

"Keep going", you hear her say. You slide in more, and after 10 seconds of pushing and squishy noises, you feel your heavy nuts reach her ass as all now-12 inches of you has slid in. You look up and give her a peck on her muzzle as you pull back and start the process over again, making sure to go a bit faster this time. You slide out, leaving your tip in and you pump back into her, going to the medial ring. You pump in and out in that fashion a few times, making sure to really get in there. You slide to the base a few more times, making some paff, paff noises as your hips collide with hers. You're really getting into it now, your thrusts becoming more methodical. You've been looking down at where your dick enters her love canal for a bit now that you don't notice her clearing her throat. 

"Eh-hem?" You look up at Twilight, she's breathing a bit heavier and faintly sweating, but is practically at resting heart rate compared to yours. "Honey, I appreciate the slow build-up, but I'm a basically immortal alicorn princess who has an near-indestructible body. You need to be better."

"Hm?" you respond, ragged breaths being confused.

"You know, blow my back out?" You look back at her confused.

"FUCK ME." she bursts out in the "Royal Canterlot Voice."

"Oh." you respond flatly. "You got it."

You slam back into her, going tip to sheath in no time, and your balls slap and bounce off of her plush plot. 

"That's what I'm talking about. Now breed this horny mare."

You begin to thrust with the most power imaginable, your hip motion rivaling the ones employed on you throughout this week in your various sexual circumstances. You begin to think about everything she's done for you, how nice it was to spend time with her mentors, her friends, and her in all those times this week. The breakfast, the movie night, and you get so lost in your thrusts that you almost miss her orgasm as her walls tighten, and you feel her fem-cum splash around your dick, making your thrusts even better. 

"Twi, I'm not that close yet, it's gonna be just a bit more!"

"I don't care! Keep fucking me, I've got more in me!"

"You're about to have a lot more in you in a bit here!"

"Then fill my womb up with your manly seed and GIVE ME A CHILD!" 

She locks her legs around you as you start to flare up, and your thrusts are now artificially short, you're going in and barely getting your medial ring out of her. Your balls are aching with cum and the repeated collisions with her butt.

"Here it comes!" you say, as you prepare your final thrusts as your flare locks in place and you slam your hips down one last time.

She cums a second time, right before you do, and your hips collide as her walls contract in the tightest possible way as you both scream and you feel yourself release. The hot cum floods Twilight's insides, filling up all the way to her cervix and around your dick as the tightness keeps the cum in. You keep pumping, locked into your lover's body as you even see her abdomen round out a bit as your output just keeps coming.  You feel the last spurts come out, as your dick begins to soften as your other body parts need blood.

"Don't...pull...out..." Twilight says, her breath heaving and her chest going up and down, glistening with sweat. "Let's...stay like this and worry about it in the morning."

The only response she got was a snore as you had already passed out, head next to her stomach, his arm draped across her torso, and dick still in her pussy.

"Fucking humans..." she eeks out with a smile, before passing out herself, exhausted and filled with hopes of motherhood.
> 8. The Day After the Last Day
> --------------------------------------------------------------------------

You walk into the ballroom as you button your cuffs and survey the scene. Since you yourself had become a bit of a celebrity, there were all kinds of creatures at this event. There were some Wonderbolts, namely Spitfire and Soarin', the "Mane Six", a popstar with black and blonde hair who you vaguely recognize, a few griffons, and a cow and a fluffy deer are talking by the punch bowl. You think you've seen the deer when visiting another land for a prize fight, but you could be mistaken.

You encounter your group as you walk in, as they were all waiting for you to arrive. The 6 are talking in a circle and you slide between Twilight and Dash as you interrupt their conversation. Dash tousles your Twilight-themed hair as your marefriend slaps at Dash's hand.

"Dash, it took forever to get that right, humans don't just bounce out of bed with perfectly styled hair like we apparently do every day."

"Sorry, egghead, just wanted to congratulate him on this past week. I'm surprised he's not a sack of bones and skin by now."

"Well, I learned a few tricks from trying to maintain this physique." Twilight says as Rarity has come over with a comb produced from hammerspace. "Lots of water, Hayterade, and some good home-cooking. Not by me, of course. The chefs here do a wonderful job."

"Well if ya ever need some a' that, sugarcube, you know where to drop on by. We got more ways to cook apples than I do cousins. And my family reunions count as mass migrations!" 

The group laughs as two Princesses come sauntering in. For non-"formal" occasions, the Princesses drop their height so they can relate to the guests better and not tower over them as much. They're down to a "meager" 6'9" as Twilight's horn gets up to their eyes and your new (surprisingly permanent) height makes them almost comparable to you.

"Good evening, my little ponies," Celestia starts, "How are you all enjoying this little "soirée" so far?"

"It's wonderful, Tia," your voice shows nearly no hesitation at referring to the demigoddess as her nickname, "you really did a great job handling this."

"Oh it wasn't all me, Luna was especially a big help. It was her idea to bring in the chocolate and cheese fountains. Those are always big hits." She points over to them as Pinkie has a fondue fork with a strawberry on it, alternating from fountain to fountain.

"Cheese...chocolate. Cheese...chocolate. Cheese...chocolate."

Dash unfurls her wings and bolts over to the fountains to intervene.
"Pinkie, no! You're caught in a sweet-savory loop!"

"Anyway..." Celestia continues, "we're glad you like it. Hopefully this isn't the last anniversary bash we have."

"Yes, it has been most pleasant." Luna pipes in, the midnight blue mare making her presence know. "Can I speak to you two alone for a second?" She points at you and Twilight and motions to head out of the venue and into the hallway. You and your girlfriend look at each other in slight confusion as you head out.

"Now, this shouldn't surprise either of you, but after our events the other day, and the total amount of magic that was involved in that, I got something you may want to see." She reaches into her small clutch and takes out a pregnancy test. Two lines, and you look at the key. Two lines equals...

"You're pregnant?!?!" you both whisper loudly.

"Yes." Luna starts. "What the fuck did you think would happen when you fucked me with a magical dick made out of your boyfriend with testicles the size of basketballs?" She whispers back, the vulgarity very out of character.

You and Twilight both agree with that statement.

"Well don't worry, Luna, we'll do our best to make sure you're comfortable during the whole process, no matter what it takes." You say, as you go in to hug the Princess of the Night. 

"About that..." Twilight says.

"What's that supposed to mean?" You say.

A white unicorn mare with dark brown hair rushes in with a clipboard.

"Guys, it's time for your speech!"

"Thanks, Raven. Twilight, we'll talk after."

You and Twilight speed-walk in as Luna follows behind at a slower pace.

You take turns stepping up the stairs, and Twilight goes to the podium and clears her throat.


"Thank you all for coming today, from The Tundra, Griffonstone, Cloudsdale, and even as far as the Crystal Empire! It's great to see so many familiar faces coming here to celebrate the momentous occasion celebrating two whole years of our relationship. It really means a lot that you were all able to come, and we hope you enjoy the festivities. We will now hear from the significantly less equine half of the relationship."

She steps aside, and you take out a couple note cards as the crowd chuckles.

"Thank you all for coming today. It's hard to express my gratitude in words alone as so many people are here to commemorate our special day. It's been 2 years and some days since I was brought to this odd land where 95% of the citizens have fur, feathers, or both. You all accepted me with open arms and even the skeptics were really only concerned with how I'd react to a certain pink mare. ("ooh! that's me! that's me! that's me!" can be heard in the distance as the aforementioned pink mare has broken the loop)." You chuckle at the interruption. "And the pony I can be most thankful for in these two years has been Twilight Sparkle. I've trusted her throughout everything with the hopes she would be putting me on the right track to help me adapt to all of the local customs and traditions we have here. And that trust was tested the most in this past week, as we worked on relationship-building exercises the whole time, and never once did I believe she would steer me wrong. And for that I am forever grateful. She never once broke her trust in me, either. I believe that trust can only be strengthened over time, so the longer the better. And I would like to ask one question to a very special woman." You turn to Twilight as the crowd starts to gasp. "Princess Twilight Sparkle, will you marry me?" You say as you get down on one knee and present to her a ring with three amber diamonds with a pink star-shaped one in the middle

"Oh, yes, yes yes!" Twilight shrieks as she hops up and down, hands over her mouth. "I would love to."

You slide the ring on to her finger as the crowd applauds and you bring her in for a hug. You whisper over her shoulder as the crowd noise rises.

"So what were you gonna say earlier?" You ask.

"Oh, yeah, I'm pregnant." She half-whispers, and the crowd suddenly falls silent as you thought you heard her words echo.

You break the hug and look out at the crowd and your eyes are suddenly wide open as you have to realize what just happened.

"The mic was on, wasn't it?" you say into the obviously still-on microphone, as your now-fiancee offers a deadpan "Yes." as the crowd collectively facepalms. They all break into laughter as you all walk off the stage and the crowd turns away as they begin to now discuss what the hell just happened.


You meet up with Cadence and Shining Armor backstage as you try to avoid the crowd for a little bit and let things die down.

"Hello, new Prince!" Shining Armor says, slapping you on the back. Now that you looked at him, you never noticed that faint purple stripe in his hair before. You gesture to yours and he replies with a face that says "Yup. Same shit."

"Hey, Shining. Nice to see you. Thanks for helping set up. And for not ruining the secret." you say as you nudge your elbow at him.

"You knew?" Twilight says, lightly smacking her brother.

"Of course I did, your hubby asked me about it before this whole week, he wanted to talk to dad about it, too. That's why I offered to help. I had to make my baby sister's engagement party the best one possible!"

"How long have you had this planned?"

"For about 3 weeks." You said. I had a jeweler from the Crystal Empire get the ring made custom, Cadence helped with that, and I talked to your dad on that one day where you had that diplomacy meeting with the Saddle Arabians."

"And now that it's official, we're going to have to start planning for the wedding, which means bachelor and bachelorette parties!!" Cadence says, slightly clapping her hands. "We're going to get so white-mare wasted that night. I could get Discord to hook us up with a Champagne cloud."

"Yeah, and I can get us glass seats for the Ponyville Polars, you like hockey, right?" You nod.  

"That's all well and good", Twilight says, "But we're going to have to wait for this little filly or colt first." She pats her stomach.

"We'll need plenty of time to plan so don't worry about it one bit." Cadence says. We'll think of everything. Congrats you two." She says as you shake hands with Shining and hug Cadence, and Twilight hugs both.

The two of you are alone now, and you finally decide to break the tension. 

"So it's really happening, huh? You're having a kid, Luna's having a kid, and we're getting married. That's a lot to take in for one night. Are you sure we're ready?"

"Of course we are, " she responds, "This week has shown me that you literally don't give a shit about some things and that if you trust me, it's going to be alright. And I know this is going to be alright."

You smile as you come in for a hug, rubbing your noses together. "You're right. As long as we have each other, thing are going to work out."

A blue rainbow-maned pegasus manages to find you as she appears out of breath.

"Guys, I don't mean to interrupt your lovey-dovey sappy time, but you might have to come get Celestia. She's caught in a sweet-savory loop."

You sigh as Twilight needs to go attend to her mentor and you want to watch and maybe get it recorded for posterity (and maybe a little prosperity). 

"Just make sure she stays away from the champagne cloud, alright?" You say to Twilight as you both jog over.

"I couldn't agree more."
