In Ponyville Rarity was struggling with a bit of a crisis with her friends, she has held this secret for a very long time. One she has kept hidden from most because she fears of being different. She isn’t a unicorn per se but rather a changeling! She has kept up the appearance of a unicorn stylist thanks to her changeling shapeshifting. The only ones who know are her own family who are baffled by this odd phenomenon. But so far the working conclusion is her great, great grandmother may have gotten a bit frisky with a changeling, thus resulting in the potential for one of her grandchildren to pass on the genetic makeup of a changeling which could leave the chance for one of them to be a changeling.

Which resulted in Rarity being one of the lucky descendants to be passed down this genetic trait. Her parents luckily were able to explain to her why she possesses such abilities along with that of a unicorn. And thankfully Rarity has used that very well, forgetting all about her changeling traits she has and shunning them away and diving deep into her work, to distract her from the fact.

And thus it had worked well until a spark of curiosity hit her. She had heard about this new farm opening and how many of the workers there on said farm were changelings and even more how Queen Chrysalis was spotted coming and going from there a few times. To which Rarity researched the farm to learn that it was a family run business that specialize in milk and magical potions too. Owned by a couple named Red Magma a unicorn and Hollow Armour a changeling. And all the others are apparently their offspring who help run the farm.

Rarity then wanted to ask Hollow how she should handle her changeling roots, considering Hollow has been all but accepted by the residents of Ponyville along with her children.

However Rarity didn’t exactly feel comfortable just going up and knocking on their door to ask about it so she had cleverly thought up a kind of ruse to not make it so obvious as to her intentions.


“Hmmm I am not sure this shade of color would suit this outfit,” Rarity says going back to her sketching table to sketch out a dress. Her clever idea was to offer up outfits perfect for the type of farming they do up there. Making sure they are both stylish and durable for their line of work.

It also helps for her whole springtime catalogue theme being all about the working pony, making clothes with a more comfortable fit and more breathable. So she is able to kill two birds with one stone.

“No no, this won’t work uuuugh!” she complains ripping the page out of her sketchbook and balling it up and tossing it in the trash before starting over. It was already late into the night but she was determined to get this done as soon as possible.

Eventually at about four in the morning she finishes her designs and gets some shut eye, now ready to put her plan into action.

The morning sun's warmth beams over Ponyville awakening all the denizens and inviting them out to enjoy the day.

Grrrrr stupid sun go away!” Rarity complains using her magic to close the curtains and help darken the room so she can continue her sleeping. “Better,” she retorts before snoozing off for a few more hours.

A little after midday Rarity awakens from her slumber and quickly gets dressed, eager to head out to the famous Milk Mine and get some advice as well as make a good business transaction.

After a bit of a trek through Ponyville she finally arrives at the farmland both Hollow and Magma own.

Walking under the large sign and up to the farm house before giving a raspy knock on the door.

The door swings open with a rather uninterested gothic changeling with purple hair standing there. She was wearing shorts that emphasised a particular bulge and a top that barely covered her bosom that read ‘bitch’ in bold letters.

“Who the fuck are you and what do you want?” she asks Rarity rather rudely.

“Ahaha how charming…” Rarity responds. “I’m looking for Hollow Armour,” she asks politely, trying to keep her sales face on.

“Mom!” the uninterested changeling yells. “Some stuck up sales cunt is at the door asking for you!” she adds before walking off.

Eventually a very shapely changeling walks up to the door.

“Come in please, I am Hollow,” she greets inviting Rarity in.

Rarity and Hollow then go into the living room sitting down on a big comfy couch.

“So how can I help you miss…?” Hollow trails off.

“Rarity, I am here to make you an offer for some farmhand designs,” she says with a winning smile, hiding her true intentions. “I have some sketches here that I am sure you will find absolutely fetching for your line of work,” she informs the bug handing her the sketches she compiled. “I assure you these outfits are one hundred percent functional for your line of work,” Rarity adds, puffing her chest with pride, while Hollow flips through the sketches.

“Well they are nice but they aren’t necessarily functional for our line of work,” Hollow says handing back the papers.

“Beg your pardon?” Rarity asks, feeling she had a surefire deal.

“Come with me,” Hollow says, leading her out of the farmhouse.

The two entered the barn where Hollow showed at the pumping station with his cock all hooked up but snoozing away was Magma.

“Wh-what is this?” Rarity asks flushed red.

“Simple, we provide both milk and cum to make potions,” Hollow explains. “Or just them regularly for anypony who wants it,” Hollow adds.

“I see and he is…?” Rarity asks fully flushed.

“Magma, our main stud,” Hollow states walking over to the cock milker but noticing it is set on the lowest setting which feels like a gentle suckle. Hollow smirks before cranking the dial all the way to a setting labeled as “Succubus soul sucker” and the machine works it into high gear.

“Wha-what the!?” Magma says snapping awake and feeling the light suction turn into a vacuum like one. “H-Hollow why are you doing this to me!?” he asks now feeling like the machine is trying to suck his nuts out of his rod.

“Remember no sleeping on the job,” Hollow titters before turning back to the now red marshmallow. “Now you see why they won't. We need quick and easy access to our fun bits here,” Hollow explains. “But I have a feeling that isn’t why you came here, right?” she asks her flat out.

“Wha-what do you mean?” Rarity asks, confused.

“I can sense it a little bit,” Hollow points out. “You are a changeling aren’t ya?” She says with a smug smirk.

“H-how did you?” Rarity stammers out.

“It’s part of my magic,” Hollow says pointing at her horn. “So what do you really want aside from selling me clothes I have no need for?” Hollow asks before sitting down next to Magma who looks like he’s in a great deal of painful pleasure at his cock being sucked in the machine.

“W-well yes I am part changeling and was hoping to ask your advice on what I should do about it,” she asks the bug. “I don’t know if it would be best to simply be more open with it or continue to hide it,” Rarity says unsure of what to do.

“Well that is an easy one,” Hollow giggles as Magma howls cumming from the machine’s powerful suctions. “You want them to accept you for you, so learn to love your inner changeling,” she explains patting Magma’s head in approval as he discharges his load into the machine to then later be used to fill up some bottles.

“That makes sense,” Rarity agrees. “But how will I learn to accept it?” she asks curiously.

“Well how about I show you how us changelings have fun,” Hollow says with a devious grin looking at Magma who manages to now detach his dick from the machine.

“Oh you mean…” Rarity trails off picking up on the lewd buggo’s train of thought.

“First let’s put your powers to the test, can you do this?” Hollow asks as she strips naked and puffs her chest out before Rarity’s eyes and her massive mammaries grow several sizes.

“Umm I never really tried,” Rarity says, taking off her blouse and exposing her own chest pillows.

“Just focus on trying to make them the same size as mine,” Hollow advised her. To which Rarity closed her eyes imagining the size in her mind and tapping into her dormant changeling powers, and she is able to make her ample bosom grow a few sizes not as big as Hollow’s currently but close to how Hollow had them before.

“Not bad,” Hollow says with an approving low whistle. “Now how about we add some junk to our trunks,” Hollow says before giving a lot more padding to her already fat ass.

“O-okay,” Rarity stammers trying to mimic the same thing once again but this time on her rear. Which to great success she adds some slight more wobble to her booty.

“Alright nice work,” Hollow says, giving Rarity’s new assets a smack to feel the soft plush wobble. “Now let’s give him a tittyfuck of a lifetime that only changelings can do~” Hollow says as the two walk up to him still panting and rubbing his now sore cock.

With nowhere to go and no time to run the two pounce at him and before long his little friend is surrounded by soft titflesh with the two of them beginning to jack him off with said melons.

“Are all stallions this large?” Rarity asks working her chesticles.

“Well depends,” Hollow states. “Just thank the fact Amazonians are size queens,” Hollow informs her.

As the two continue to slide their sweater stretchers along his meat pole, drawing out some of his pre cum from this endeavor. Hollow extends her tongue using her changeling powers to make it longer as she laps up the pre forming on his blunt tip. Seeing this, Rarity reaches down to massage Magma’s poor nuts carefully caressing them with her playful hand and giving the occasional squeeze.

Nnngh gonna bust if you keep this up,” he warns the duo which only results in them redoubling their efforts, eager to make him erupt.

“Come on let all that hot seed out all over our tits~” Hollow teases flicking her now lengthened tongue across his tip.

“Here it comes,” he forworns them as his sack tightens in Rarity’s grip and cum rushes out of his cock and literally erupts and rains down on their massive boobage. The two mares stick out their tongues catching the occasional stray blast on their tongues giving them a bit of a taste of his fresh nut butter.

After a while his orgasm dies down and they remove their cum coated tits from his shaft, but soon replace it with their wobbly bottoms.

“Next up let’s give him the same treatment with our asses!” Hollow cheers.

“Of course my fellow changeling!” Rarity responds

“Celestia help me,” Magma cries out as the two begin grinding their derrieres against his tender rod once more. He is utterly helpless against these two changelings and will be stuck for a while.

So that's how changelings feel

“Alright ready now shake what your momma gave ya!~” Hollow instructs the fellow big butted Rarity who struggles to keep up with Hollow’s twerking against the massive red shaft.

“I-i am trying my best!” Rarity proclaims throwing her ass to match Hollow’s speed against the red rocket.

“Try harder!” Hollow shouts.

“Do I get a say in this!?” Magma asks his poor tender donger throbbing.

“No!” the duo say in unison, while continuing to grind their rumps against his pole.

“Wish we had a magic boombox like Trixie has, might have helped to have some music for this,” Rarity chimes in feeling the mighty spear twitch and throb and produce pre cum to coat their booties.

“Less talking, more ass grinding!” Hollow booms as the two speed up to as fast as their asses can clap.

“Fuuuuuuuck!” Magma announces as he begins to fire his sticky load between the duo pair of cheeks.

“It’s raining, it's pouring, the big cock is spurting!” Hollow cheers.

“I don’t think that’s how the rhyme goes,” Rarity points out.

“Who cares,” Hollow points out as Magma’s spooge rains down, painting them white and emptying his nuts fully. And slumping back his body from exhaustion, having been brought to powerful orgasms twice by these sexy changelings.

“Phew that was quite a work out,” Rarity says as she wipes a bead of sweat from her brow.

“Yup, I have been trying to launch an exercise program that promotes sex as a work out,” Hollow points out, walking over and lifting Magma’s head to one of her breasts and feeding him some of her milk. “So any more questions on changelings?” Hollow asks the marshmallow unicorn.

“Yes I do, would I be able to feed like normal changelings do?” the white unicorn asks.

“Hmmm hard to say,” Hollow responds. “You are only like a quarter changeling or something along those lines, and frankly I’m from a different hive then Chrysalis’ brood,” Hollow explains. “I feed more on and get full on lust as opposed to love,” Hollow continues. “But it helps feed and sustain us more than regular food would and plus if you can get a supply of liquid love,” Hollow finishes still breastfeeding Magma.

“Liquid love?” Rarity question before watching Sneak cup and jiggle Magma’s nut sack.

“This kinda liquid love,” Hollow points out. “To any kind of changeling this is the best stuff to get full on,” she adds. “Plus it helps when wanting to emphasize certain body parts but they go back to normal after digestion usually,” she continues for the next few minutes explaining a lot about changeling biology to the marshmallow, all the while feeding Magma her milk to restore his stamina as he napped.

“Wow, I didn’t know all this,” Rarity exclaims in astonishment. “I feel like I should be writing this down,” Rarity notes to herself.

“Eh you won’t need to know as much after all you said it was one of your ancestors who was half changeling,” Hollow informs her. “So you probably only have a hint of changeling meaning your abilities will be limited compared to me and other changelings,” Hollow tells her as the barn door opens and closes.

In walks a young adult looking changeling with a red mane that splits into two pigtails that hang down almost to the floor but stopping around the knees. As she approaches Rarity notes surprisingly her bust is rather small compared to the titanic titties her Hollow sports, only being about what she would guess a D cup, but as she looks down she sees what she lacks in breasts she makes up for in ass. Her hips wide as most stallions would dream about and the buns that would devour a cock if it was let free and clapping almost with each step unintentionally.

“Mom!” the changeling whine in a high pitch tone. “Queenie and Sneak got into another argument and are now sword fighting with dildos!” she complains in the same tone with a hint of attitude added in. “And they’re supposed to help me with today’s delivery!” she adds on with a stomp on the floor for emphasis.

“Again with that?” Hollow asks seemingly as this is a regular occurrence. “Serenity just go take Thunder Cath and Yubie then, and I’ll let them know this comes out of their allowance,” Hollow informs her daughter.

“Ugh fine!” Serenity complains glancing over to Rarity. “Another cum dump? Like we don’t have enough of those for dad around here,” she mumbles before taking off.

“Sorry about that,” Hollow apologizes.

“No harm done, not thrilled about being called a cum dump tho,” Rarity responds, slightly wounded at the claim.

“She just puts up a rough exterior, but she is a real sweetie deep down,” Hollow says, popping her nipple out of Magma’s mouth seeing his flag raised to attention. “Speaking of something going deep down, it’s about time you should be fed,” Hollow purrs, looking Rarity straight in her eyes.

“Ummm… that is mighty generous of you,” Rarity blushes, turning crimson.

“Please I insist after all you wanted to experience being a changeling,” Hollow says getting up and suddenly from her crotch a sheath appears with a large blue horse dick jutting out along with a sack of two apple sized balls appearing. “And what better way than a double dose of liquid lust,” Hollow purrs once more using her magic to lift the blushing Unicorn up and drawing her into the waiting arms of a changeling hug. Without wasting a moment Hollow plants a big kiss on Rarity letting her be fed some love which slowly gives Rarity a warm sensation as well as a hunger for more.

“Oh heavens this is an intoxicating feeling,” Rarity notes looking at both Hollow’s and Magma’s fuck sticks.

“So how about a taste?” Hollow asks, shaking her erect wiener for emphasis.

“Oh I will but first let me take a seat darling,” Rarity says as she sashays over to the still snoozing Magma and promptly impaling herself upon his mighty spear but only getting a good third of it inside her. “Oh my, much more difficult than I thought it would be…” Rarity grunts and groans hoping her body would be able to take him in one go.

“Trust me it takes a pro to take his bitchbreaker,” Hollow reaffirms. “I still have trouble taking him whenever I retighten my cunt, but on to more pressing business,” Hollow seductively says as she places her hands on the shoulders of Rarity and pushes her down to be able to take him whole until a wet plap sound is heard from her bottoming out on his dong. “Speaking of, get to sucking bitch,” Hollow says, grabbing Rarity’s head and shoving her tallywhacker down the gullet of the inexperienced pony. “Nice and warming and inviting aren’t you,” Hollow chides as she begins to move her hips and uses a little magic to make Magma’s do the same.

Rarity’s senses were overwhelmed with that warm feeling once more, her changeling half really being fed an obscene amount of love at the moment. Giving her a sensory overload of pleasure a changeling feels at times.

“Enjoying it?” Hollow asks, grasping Rarity’s horn to guide her head further down her pipe. Enjoying the rough throat fucking Rarity is recieving from the veteran changeling. The sensation of being taken from her leaky snatch and maw is too much for Rarity as she is fed a bit too much as her boobs without her meaning to begin to swell and grow a few cup sizes bigger.

Hollow notices and chuckles as she redoubles her efforts as well as adding more magic to Magma’s hips who pound with unrelenting mercy, bludgeoning her womb with his flaring tip. Each upwards thrust spreads her wide open, marking her hole as one only he could take pleasure in, like a well fitted baseball glove. Her vaginal walls hugged the intruder like a long lost lover not letting go and squeezing every single inch and vein.

“Look at you now, all fat titted and getting fucked in this barn, may as be one of our cows huh?” Hollow teases as she continues to thrust causing Rarity to gag quite a bit. “I’m gonna cover those massive melons with my cum, mark you as ‘Property of Hollow and Magma’s Milk Mine’ like the sound of that?” Hollow continues with her dirty talk, her sack begins to tighten as her twin cum factories go into overtime to begin pumping nut butter out soon.

The same can be said for Magma who is now waking up from his post orgasm nap to find he is balls deep in Rarity, and on the verge of stuffing her with his baby batter.

“Wha-what is going...nnnngh!” he lets out as his dick erupts, flooding Rarity’s cunny with enough seed it may just end up being glued shut.

Rarity’s eyes cross as she orgasms and feels the rod inside her twitch as it’s pulled out and begins spraying spooge all over her face and enlarged boobs.

“Fuck yeah!” Hollow lets out as she pumps her cock to thoroughly coat Rarity.

Magma shakes himself awake feeling his orgasm die down.

“Care to tell me what just happened,” Magma questions his lover.

“Rookie mistake although I may have had to do with that,” Hollow says with a wink.

“I see that,” he responds, pulling his dick out of the stuffed snatch letting a cascade flow free.

“Oh my I am practically seeing stars…” Rarity adds.

“Care to give her the full Milk Mine experience?” Hollow suggests.

“Can do,” Magma then pounces, throwing Rarity’s legs over behind her head, pinning her to the floor in no time at all .

“Oh dear so forceful,” Rarity coos in excitement as Magma lines up his dick and slams it back into the cummy swamp of her cunt, and begins treating her like a personal breeding sow.

“Don’t mind me, but I am just gonna sit over here,” Hollow informs as she sits on a nearby stool and begins jerking off to the scene she is witnessing.

“Oh Celestia I’m cumming!” Rarity announces her whole body clenching up as she sprays pussy juice all over Magma’s sack

“Yeah cum for me and moo too cow moo!” he barks, really showing his dominant side. “Moo and get my seed!” he proclaims.

“Fuck this is hot…” Hollow comments jacking herself faster.

“Moooooooo!~” Rarity let’s out.

“Good!” Magma declares. “Now take my blessing!” He barks as he unleashes a whole new wave of nut butter into her already stuffed snatch.

“Oh shit…” Hollow mutters as her own donger showers more spooge onto Rarity’s cum covered body, painting her white and marking her as property of the Milk Mine.

The couple promptly empty themselves both in and on Rarity till she can’t take anymore and blacks out from her orgasm and far too much love. Eventually with the duo’s orgasms dying down.


“And as such I think a certain cowling is about to get fucked until she has multiple prostate orgasms,” he adds stroking his cum coated cock that is still erect.

“Moo~” Hollow responds, leading him into a stall.
