“Please some pony hear me and- and use me” Rainbow moaned out quietly. She was above the Ponyville marketplace at its busiest, laying on a cloud. She had her back against the cloud, her wings spread out wide. Her hind legs open exposing herself as much as she could to the open sky above her.

Her fore hoof was rubbing her pussy madly. Her fur was soaked by her arousal as she was dripping liquid at a steady rate. The pegasus was panting and moaning openly as she was not really trying to hide herself, she wanted somepony to catch her and use her. 

It was by far one of the cyan pegasus’s biggest fetish’s, the idea of being used as nothing more than a sex object. A wet hole to stuff cock into, a tongue to lick a pussy. It made the mare wet just thinking about it. 

She had fantasies of being dragged into an alley out of nowhere. Held down by magic, hooves, talons it didn’t matter, then the ones who had taken her would use her body as a sex toy. Dash knew she would end up begging for more abuse, for their cocks to cum deep in her pussy and fill her. To lick the marecum from a marehood that smothered her mouth.

Rainbow didn’t know why it turned her on so much, maybe it was the lack of control, the loss of freedom or how wrong it was. She knew just wanted to be below somepony, to have a Master, Mistress or Owner. To be their pet or slave. 

Rainbow shivered in pleasure as her hoof tip pushed into her wet opening. What if they changed her body? Reshaped her body to suit their purposes and desires. Make her tongue longer so she could reach deeper in some mare's wet depths. Her hot tunnel remade to fit her Owner’s cock in the perfect way. 

Or maybe give her a cock of her own so she had both a cock and a pussy. Rainbow could ride toys or dicks deep in her pussy while stroking herself, cumming all over herself for her Owner. Maybe all over her Owner’s body if they liked it. She could satisfy her would be Mistress, ramming her cock deep into her. Then she would be deep in her pussy and cum filling her Mistress up with hot seed. 

What if they stopped her from cumming? Used magic to keep her on the edge. Rainbow’s eyes rolled back at the idea. She could imagine it clearly. Her Owner edging her for hours, not letting her cum. Using whatever they pleased on her marehood bringing her to that edge, but never over the edge. 

Then sending her home or to her dog bed still with the burning urge to cum but she wouldn’t be able to. She would be free to play with her pussy but no matter how much she tried she wouldn’t be able to get release. She would be constantly dripping pussy fluid, her sex burning wonderfully with need. As she was denied orgasm again and again. Each time making her crave release more and more till she was a panting begging mess. Some ponies would call it a Nightmare being denied orgasm like that but for Rainbow that sounded like heaven. 

Rainbow’s back arched as pleasure ran up her spine when her hoof brushed her clit. “I want to be caught.” She whimpered out desperately. Her other fetish was just as strong as her first. It was being watched as she masturbated or was fucked. She had looked it up in one of Twilight’s books at one point and found it was called Exhibitionism, so she was an exhibitionist, if she used the word right. 

She was right now on a cloud, her body on full display so any pony who looked at her could tell she was masturbating. As her cyan hoof was hard at work rubbing her aching marehood. Her wings were flared wide, helping draw attention to her body. 

The cloud she was on was high in the air, flat and was twice her size giving her room to spread out. She could hear the sounds of the Ponyville marketplace below her as she worked her pussy juice soaked hoof tip deeper in her opening, desperate for release. She knew it was going to take more then one or two orgasms with how aroused she was today. 

“Please..somepony….see me and claim me.” Rainbow moaned hotly as her hoof stretched her wet folds as she pushed a little harder, trying to get all of her hoof in aching sex. 

“They don’t even need to ask, just use me-meEEee.” Rainbow’s eyes shot open as magic started playing with her marehood. It was gentle as if asking permission from her. The magic felt familiar but she couldn’t place it with her aroused mind. Regardless somepony was out there using their magic on her pussy. 

Rainbow hadn’t ever cum so quickly before. Her back arching as her pussy was squirting marecum out of her. Her entire body tensed with her soaked hoof becoming still as she came. With Rainbow only able to barely say “Thank you, Thank you, Thank you.” 

Rainbow’s orgasm ended but the magic didn’t stop, no, it went deeper opening her pussy to the cool air. The magic started exploring her depths making her moan in delight. “Hhhhaaaaffff.” Instead of telling whoever was using their magic on her to stop, like any normal pony, she started moving her hoof again. Moaning as she did so. 

How could she not?, her biggest fetishes were happening to her. She was being used above the Ponyville market in the middle of the day. Rainbow did not want the magic playing with her pussy walls to stop. The magic felt so good as it explored her fuck tunnel making her moan for more. “Don’t stop…. please don’t…. make me cum as..as..many.. times as you want…. my body’s y-yours to play with.” 

Rainbow felt the magic go deeper brushing past a particularly sensitive part of her aching, needy marehood. Making her gasp as her back arched as orgasm rushed up to her.... but it never happened; she didn’t make it over the edge, she was balancing on the edge. The magic must have stopped her from cumming and was keeping her on the edge.

Her hoof motions got faster eager for more “T-Thank you…gaaaa…..don’t stop…. use me.” She was in heaven, somepony had caught her and brought her to orgasm. Now they were denying her orgasm. Tears of bliss formed in her eyes as she was writhing in fetish fueled pleasure. Her fantasy was coming true. Now she just needed this pony to make her their plaything, to claim her as their pet, slave, toy it didn’t matter. 

She felt magic be applied to her eyes closing them as Rainbow didn’t fight the magic. The exposed mare then realized she had not seen the color of the magic yet as that would have given who it was away. Clearly whoever it was didn’t want to be known, at least not yet she hoped.

Then she stopped hearing the world around her. She could no longer hear or see the world around her. It should terrify her, being deprived of her senses by somepony she didn’t know. But instead she submitted letting the unknown pony have free rain over her. Rainbow didn’t stop her hoof from moving as the pleasure of her fetishes being full filled was too good.

“Please don’t stop… it feels so..haaaaf ...good.” Rainbow begged the feeling of her orgasm being held back was amazing. With her knowing that she was at the will of some unknown pony for when she could cum. “Con-Control me please..” the thrill of not knowing who she was at the mercy of was exhilarating. She felt another orgasm become denied as she kept her hoof rubbing her clit.

Then she felt a hoof be placed gently on her chest. Dash gasped at the physical contact. Then Rainbow moaned deeply. The unknown pony was touching her! She had no idea who was touching her; it could be any pony. She was too focused on the pleasure of the entire experience to try and piece together who was touching her. The pegasus then felt the hoof begin to sensually move down her chest towards her heated marehood. “Please…Use me.” Rainbow begged, she needed the hoof to rub her folds.

Maybe the unknown pony was inspecting her body. Feeling each muscle as the hoof passed over them. Seeing if she was a good catch. Rainbow could even feel the hot gaze of the pony looking at her even with her eyes closed, making her shiver.

Each inch the unknown pony’s hoof traveled down her chest felt like lightning to the sensory deprived pegasus. Each inch closer the hoof got closer to her wet sex the shaper the lightning got. She felt her own hoof being pushed out of the way as the pony’s hoof got closer to its goal.

Then just before the hoof rubbed any sensitive areas. The spell on her pussy went away. She came instantly spraying her marecum into the air. Rainbow almost screamed in bliss but remembered that she was still above the Ponyville marketplace. She tried to cover her mouth with a hoof to muffle the sound but the unknown pony kept her hooves in place using magic.

So she kept her mouth shut and did her best to muffle herself as the pony was also holding her wings down with magic. After what must have been thirty seconds she felt her orgasm stop. Then as soon as she stopped cumming the hoof of the unknown pony started moving. 

“Yes…. use ...me” Rainbow moaned out. She was desperately hungry for more. 

The hoof was slow as it moved down the tip opening her wet folds. The feeling was electric as the hoof started to make rings around her dripping tunnel. Then after a few loops around the outer edge of her pussy. The hoof moved to rub her clit softly at first making the submissive pegasus moan. 

Then to her surprise she felt a other hoof poking her mouth. She opened her mouth and started licking the hoof. It was wet with what had to be the unknown pony’s pussy juices. It had a taste of lavender to it making her want more. The hoof she was licking was removed making her whimper. Then the hoof playing with her marehood stopped and left her body. “No.. don’t stop.. please.” Rainbow begged the unknown pony desperately. She didn’t want the pleasure to stop, she didn’t want her fantasy fulfillment to stop here.

Then she felt something prod her pussy, the tip was wet hot and hard. She realized a cock was rubbing her tunnel entrance. The shaft felt huge against her nether lips ready to claim her. She then heard a command. 

“O-Open your eyes.” 

Rainbow obeyed and did so. Dash was rewarded with the best sight she had ever seen. Her wonderful wings were flared out in arousal. She was panting deep and lustfully like she was. A deep blush ran across her muzzle but she had a determined and somewhat confident look in her eyes. It was Twilight.

Both mares were silent for a moment as they looked into each other’s eyes. A deep blush forming on Rainbow’s muzzle. Rainbow then wrapped her fore legs around the alicorn’s neck. “Twilight don’t stop please…. I-I need this.” Rainbow begged as her hips bucked backwards trying to get the cock to enter her aching pussy.

“Then a-ask me.” Twilight said as she teased the submissive pegasus’s marehood with her alicorn cock. Twilight wanted, no, needed to hear the pegasus say it. 

Rainbow spoke, her voice shaking filled with equal parts trepidation and anticipation “Twilight c-can I be your pet?” Rainbow almost came as she asked the question. Rainbow wanted Twilight to be her Mistress badly. Rainbow felt pressure on her marehood’s entrance and Rainbow pushed back panting. 

“If I can be your Mistress, Rainbow.” Twilight answered hotly as she wrapped her forelegs around Dash’s neck and lowered her head so they were nearly muzzle to muzzle. Then rested her chest just above Rainbow’s. “So y-yes Dashie if you want it I-I will be your Mistress.” Twilight whispered, sounding almost as desperate as she had. 

Rainbow nodded moaning as her fantasy was coming true, she desperately hoped this wasn’t a dream. Twilight Sparkle her Mistress, the sexiest mare in the world, wanted her as a pet. “Don’t let this be a dream.” 

Twilight moved her head and bit the hollow between Rainbow’s head and neck, hard. The bite hurt in the most blissful way, this was real. Rainbow shot to an orgasm instantly screaming silently doing her best to keep quiet. 

Twilight’s horn flashed and they appeared in the alicorn’s bedroom in the castle. On her bed. She didn’t want to be interrupted.

Twilight moaned as she felt the pegasus twitch underneath her. “I didn’t even put my cock in you yet.” Twilight looked the pegasus in the eyes. “You're a slut aren’t you, Rainbow?” 

“Mmhum.” Rainbow whimpered nodding as she came back down from her orgasm. 

Twilight smiled like she was a predator who had just found the perfect prey. “Rainbow, you're going to be my slut understand me?” Twilight started slowly pushing her alicorn cock against the pegasus’s entrance making her gasp. Then the pegasus started pushing back, trying to get the throbbing marecock in her body, the head was so close to entering her hungry depths fully. 

“I’m your slut Twi- Mistress.” Rainbow answered passionately, she needed Twilight to be her Mistress.

Twilight rested her head above Dash’s and lowered her lavender wings to pin Rainbow’s own cyan wings to the bed. “Good girl.” Twilight moaned as she pulled her hips back. Rainbow whimpered.

“Now I’m going to make you mine.” 

Twilight thrusted her cock with the strength of a lustful alicorn, pushing her cock halfway into the pegasus’s hot tunnel in one rough thrust. Rainbow’s pussy was like a vice as the wet walls gripped her cock unbelievably tight. The velvet tunnel felt like a furnace compared to the outside world. She loved the feeling. The alicorn moaned “mmmf.. oh.. Rainbow.”

“Oh.. fuck yes!” Rainbow’s body went rigid with pleasure. She had trouble focusing on the alicorn, her cock was so big it felt like she was being split into two. She was being stretched by her Mistress’s cock almost painfully so. Her Mistress was forcing her worthless body to adapt, her pussy to change and stretch for her cock. The monster shaft throbbed as Rainbow felt precum leak from the tip. Rainbow needed all of the cock in her fuck tunnel. 

Twilight started slowly moving her alicorn cock in Rainbow’s pussy and gasped at the incredible feeling of the wet tunnel walls trying to make her cum. “R-Rainbow….. feel your Mistress’s cock force you open.” Lust layered the alicorn’s words. 

“Mistress feels hgggg…. so good.” Rainbow panted out as her body shook in pleasure. The movement of Twilight’s shaft was blissful with a very slight burn of pain that drove the pegasus wild. 

Twilight pushed deeper into the pegasus’s heavenly pussy whispering “That's it open up for y-your Mistress and take her cock like the slut you are, pet.” 

Rainbow reached orgasm again, that word meant so much to her. She was now a pet to Twilight. She was less than Twilight and that felt good, it felt right. She relished how her chest heaved desperately trying to get air in her lungs as Twilight kept going deeper, it started to hurt just enough for tears to form in her eyes.

This made the alicorn pause her movement, “Rainbow if-“ she was interrupted by the submissive pegasus. 

“Don’t stop… it feels so good… don’t stop...... please don’t stop… fuck me.. change my worthless body… ruin me… make me scream, treat me like a slave… make me scream your name in pain.... just don’t stop.... claim me.” Rainbow begged desperately like her life depended on it. 

Rainbow’s begging lit a primal fire deep with Twilight.

That predatory look returned to Twilight. “Looks like I’ve caught myself a pet who is not only a submissive slut and exhibitionist but a masochist as well!” A lustful growl left the alicorn’s throat, one that made Rainbow shiver as Twilight started again but at a much more brutal pace. Each thrust came with a small spike of pain that instantly turned into pleasure but still burned.

“You’re going to belong to me, Rainbow.” Twilight moved her hind legs to pin Rainbow’s down. “I’m yours Twilight.” Rainbow moaned back as Twilight held her in place and any semblance of control the pegasus had leftover was taken from her, like it should be.

“I’m going to change you.” Twilight said as her cock got deeper in her pet pegasus. “Change my worthless body.” The idea made the pegasus shiver.

“You’re going to be my cock sleeve and I’m going to use you daily. You’re going to keep my cock warm each night and wake up to being fucked.” Twilight thrusted faster.

“Do it, please do it” Rainbow moaned, that sounded like heaven to her.

“Oh I will, Slut and I am going to train you to be the perfect pet too. And if you are a good slut for me I will reward you with a long hard cock of your own.” Rainbow nodded profusely her tongue sticking out as she panted. 

“And I’m going to ride you and you're going to fill my pussy up.” The alicorn felt the fluid running down her leg as she forced Rainbow open. Get more desperate moaning from Rainbow.

“I am going to use you when I feel like it. Even if it’s right in front of our friends.” Twilight knew she was getting close to cumming. “Yes.. please.” Was all Rainbow managed to moan out.

Rainbow felt the alicorn’s marecock reach as deep as she could take it but she hadn’t taken all of her cock. “Don’t worry we will work on that.” Twilight whispered hotly as she continued thrusting. Rainbow experienced a mini orgasm each time Twilight slammed her cock head against her hot depths.

“There’s no going back Slut. I've seen who you really are and it’s beautiful. But you belong to me now.” Twilight was going to cum soon, she could feel it.

“I don’t.. to ever..want to go back.” Rainbow moaned out. 

Twilight felt the point of no return pass. “Cum for me, pet.”

Rainbow felt bliss rack her body as the head of Twilight’s marecock flared. “Claim me! Make me yours!” Twilight could hear the submissive pleading in her voice. See the desperation in her beautiful magenta eyes as her pussy clutched her cock like a vice.  

The dominant alicorn growled, low and primal, she came hot, firing thick bursts of cum as she fucked Dash through the orgasm, kept pumping her hardest when her pet was so sensitive. “Good girl, take my cum.” Twilight whispered hotly as everything that wasn’t her and her pet became irrelevant. 

Rainbow screamed in rapture tightening her grip around Twilight, holding on to the alicorn as she rode the waves of ecstasy that consumed her. She lost the meaning of time as all that mattered was the pony she clinged to desperately as her womb was filled with hot cum by her Mistress. Each load the alicorn fired pushed her deeper into the waves of ecstasy. Deeper and deeper she went till Rainbow passed out from the pleasure.

Twilight was having trouble processing what had happened with Rainbow, still was. The cyan mare in her bed had acted so differently to what she knew of her.

She hadn’t acted like that headstrong pegasus who would easily charge a full grown dragon to protect her friends or the cocky mare who let no pony down. Dash had been incredibly submissive the entire time. She clearly liked it as the pony kept begging to be her pet and begged her not to stop.

Twilight knew she had gotten lost in the heat of the moment as Rainbow’s begging had done something to her. She didn’t quite know what however…. no, that wasn’t quite right. She knew what had happened. She was more surprised at what she had herself done and said. 

She had called Rainbow a slut repeatedly and she had revealed in the action. Telling the pegasus that she belonged to her now had felt natural, almost instinctual. She also couldn’t bring herself to even think about not following through on her words. She wanted to make Rainbow her pet and control her. Was that why she made Dash beg for it? So Rainbow gave up control to her?

Twilight felt the pegasus wiggle tighter into her hold, Dash's head nuzzling deep into her lavender chest fur. Twilight pulled the pony closer without thinking, wrapping her wing around the mare’s back. Twilight was holding her friend against her barrel. Her shaft was currently out of the way by her using a bit of magic. 

Twilight looked at the pegasus in her hooves; she was a mess. Her coat was matted with dried sweat and marecum. Twilight knew the mare’s thighs were stained with her cum. The thought made the alicorn smile. Dash’s belly had a bump that was filled with her seed as well making her look adorable with sexy throw in. The best part was she had done this to Rainbow and the mare had screamed for more.

Twilight closed her eyes and simply listened to Rainbows breathing. She was breathing slowly but calmly.  She could feel happiness in each breath she released. The cute sounds she made filled Twilight’s chest with a light airy warmth.

The alicorn remembered each moan and sound the pegasus made as she had claimed her. Each one played out in her head making the alicorn want more. She wanted more moans to leave Dash’s muzzle and reach her ears. She wanted to hear Rainbow make more of those wonderful sounds again. Then hear her beg-

Twilight bit her lip to try to calm her rising lust. But her alicorn libido was making the action very difficult for her. Thankfully after a minute or two she managed to cool the fire down to a low constant simmer like normal. 

Twilight started slowly petting the mare’s rainbow mane. The action felt right as if she was doing something she should have been doing for a while. Twilight knew she wanted to be the pegasus’s Mistress as how could she turn down the idea of having Dash as her ‘sex toy’. But before she could make any final decisions she had to talk to Dash first.

So she waited, listening to Rainbow slow breathing. 





Rainbow woke to the feeling of a hoof running through her mane. She felt a blanket laying on top of her and a pillow under her head as well, making her feel inordinately cozy. 

The hoof was soft and gentle as if it was touching something the hoof cared for, something precious. Rainbow coed softly as she leaned into the petting getting a giggle from the pony who was petting her. The pegasus opened her eyes to look at the pony petting her. It was Twilight and she was holding her in her legs with a wing over her back that was under the blanket.

Rainbow realized that they were still in Twilight’s bedroom but the bed looked and felt fresh. Twilight must have changed the sheets or used magic to clean it while she slept. 

Twilight then leaned towards her and kissed her with the alicorn’s hoof holding her head in place as she deepened the kiss. It was a slow paced kiss, one that Rainbow melted into immediately with a moan leaving her throat at the dominant alicorn’s actions. Both ponies took their time with the kiss with Twilight controlling the movement of her tongue. After almost a full minute Dash felt the mare pull back from the kiss but gently bit her tongue as she left. 

Then a blush exploded on the alicorn’s muzzle “S-sorry, I couldn’t help myself.” She said. 

Everything felt unreal to Rainbow. Here she was in Twilight’s bed with her lavender hoof petting her mane, which she really liked. But she had passed out at the sheer overwhelming pleasure of the same mare fucking the daylights out of her. She could still feel some of the alicorn’s warm cum in her body and she liked that feeling.

“I uh thank you? I-I don’t know what to say, honestly.” Rainbow admitted.

“Well most importantly did you like what happened?” Twilight asked Rainbow as that was the most important question in Twilight’s mind right now.

For Rainbow that wasn’t even a question. “It was awesome Twilight, really awesome. I definitely want m-more.” Rainbow knew she was blushing; she could almost feel the burning of her muzzle. 

Twilight let out a sigh of relief. “Thank goodness when you passed out I worried I went too far. But next I have to ask Rainbow, how far do you want to go? We said a lot of things in the heat of the moment. But did you really want all that?” 

Rainbow after a second responded with a embarrassed smile on her muzzle “Yea I do, I want to be your pet, your s-slut, Twilight. What I said was what I wanted.” 

“So even the whole ‘change my worthless body’, ‘ruin me’ and when I told you you're going to be my cock sleeve.” Twilight offered with an impish smile.

Rainbow nodded “All of what I said and you said, I want. The idea of waking up and being immediately fucked by you or falling asleep with your cock in my body is hot, really hot.” Dash said with an almost dreamy look.

Twilight nodded then asked “So how much do you ‘belong’ to me?” It was a question that needed answering. 

“It would be awesome if it was completely Twi, I want be used as nothing more than a sex toy. My body is yours to do with as you please whenever you want to.” Rainbow said with a sureness that reinforced her choice in Twilight’s mind.

“Then I need you to give me a way to consent and a way to tell me to stop.” Twilight said firmly.

Rainbow chuckled nervously. “I have had plenty of time fantasizing about this Twi. The words would be green, orange, red and me flapping my left ear three times in a row is, no slash stop. Then me flapping my right ear three times in a row is, yes slash continue.”  Rainbow stated she had years to think of this part of being a pet.

“Good, that’s plenty to work with Rainbow, thank you. You have wanted this for a long time haven't you?” Twilight playfully accused Rainbow who nodded sheepishly. 

“You have no idea.” 

“So pet what do you want first?” Twilight asked, getting a shiver from Rainbow. 

“I want you to start ‘training’ me now.” Rainbow said, her blush reforming with a hopeful smile.

“But which to do first?” Twilight pondered as she slowly untangled herself from Dash then stopped gaining a grin. “Actually I know exactly what I will do first. But I have to teleport to get it and it might take a moment. So in the meantime get cleaned up in the bathroom then wait in the middle of the room for me.” Rainbow nodded as Twilight disappeared in a lavender flash. Leaving her in the bedroom alone so she did as told.

Rainbow got out of the bed and headed into Twilight’s bathroom. 

The first thing she saw was a floor to roof mirror to her left with a cabinet to it’s right and a bath mat in front. A blush colored her cyan muzzle. How could she resist? The answer was she couldn’t. 

Rainbow moved in front of the mirror and started to inspect herself. She was a mess of matted fur. The first big thing she found was where Twilight had bit her. In that hollow between her head and neck. There was a small bruise that was barely noticeable at a glance. She lifted a hoof and touched the bruise letting out a moan. She wanted more marks like the bruise. 

Another smile crossed her muzzle as her blush deepened. 

She then repositioned to be laying on her back with her marehood facing the mirror but she had her hind legs closed. So her eyes were unable to see her slit. Rainbow put a foreleg on her chest feeling the small bump. It had to be Twilight’s cum in her womb, if she had been in season Twilight would have easily bred her. She could also feel a spell Twilight had placed in her and knowing Twilight she had made it so she couldn’t be bred.

She spread out her wings instinctively as well. Rainbow let out a coe as she circled the bump. Then she slowly started opening her hind legs slowly revealing her marehood to herself. She imagined herself in front of a small crowd slowly showing what her Mistress had done to her pet. 

The sight was amazing. Her cyan fur on her inner legs was soaked with her own marecum and arousal. It looked like she had been dripping arousal for almost a week then taking extra care to rub the fluid in her cyan coat. Her inner thighs were stained the perverted white color of the alicorn’s cum. Her cyan fur was utterly ruined and the stain was going to be impossible to hide if she walked normally. The area around the base of her tail was also colored white now thanks to Twilight.

Then there was her pussy. Her tunnel was parted open slightly more than before Twilight had fucked her. The Princess had forced her pussy to open in the most wonderful way with her alicorn cock. She had pushed her open and used her like she should be. Now Twilight’s cum was slowly trickling out of her as she was overfilled with the mare’s wonderful cum. She looked like the slut she was.

What Twilight had told her rang in her mind. “Don’t worry we will work on that.” She hadn’t been able to take all of Twilight’s cock. But she was a pet now and she had to be able to pleasure all of her Mistress’s cock with her marehood. She needed to be a warm hole for Twilight. 

Without thinking she lowered a forehoof and started rubbing herself, Rainbow watched herself as she looked through the mirror. She started off at an even pace as she didn’t want to take too long as she had to still clean up herself for Twilight. But she had to indulge herself; it just felt too good to ignore. Her hoof was quickly soaked once again and this time with her Mistress’s cum as well. 

Her Mistress’s cum as well. 

Rainbow switched gears and pushed her hoof tip against her opening. Her hoof spread open her folds as she got her hoof as deep as she could. Then she quickly brought her hoof to her mouth and started licking, forgetting her pussy for the moment. She tasted herself as she had a hundred times before on her hoof.

But now she also tasted a new flavor: her Mistress’s cum. The liquid tasted deeply salty with a sweet candy like aftertaste that made the cum addictive. Dash moaned as she licked her hoof desperately trying to get as much of the alicorn’s cum as possible. Once she licked her hoof clean of fluids she smiled as an idea went across Dash’s mind as her hoof restarted to play with her pussy.

She had to have more of the deliciously addictive cum and she knew just how to get more. Rainbow placed her free foreleg to her side for balance after stretching briefly. She then lifted her hindquarters up towards the roof while keeping her neck and  chest against the ground. 

With little trouble she bent her flexible body towards her muzzle removing her hoof at the same time. She used her wings to help her stay in place as her goal got closer to her mouth. Then when she reached a tipping point she let gravity do the rest of the work in pulling her hindquarters to her.

Her reward was her own pussy a inch above her muzzle, easily reachable with her mouth and tongue. With her hind legs next to her head. Rainbow pushed her mouth to her opening and started licking her outer folds. She hummed happy as she focused on getting as much of the cum she had leaked out. 

Then Dash pushed her tongue into herself getting the succulent taste of her Mistress’s seed for her efforts, moaning as she did so. She used her tongue like a shovel scooping out more of her Mistress’s cum with each lick. Getting more of the taste that she was quickly becoming addicted to as the mare swallowed each drop she could get out of her own marehood. 

She lifted her forelegs and wrapped them around her hindquarters and pulled downwards as she pushed up her muzzle upwards. Rainbow hoping to get her tongue deeper into her hot pussy. Getting more of her arousal all over her muzzle as Dash forced herself deeper in. 

Rainbow pushed her muzzle harder against her marehood getting her muzzle just a bit deeper. Letting her tongue find more of the delicious cum to taste. She was getting close to cumming. The thought she was going to cum from licking her Mistress’s seed out of her own pussy pushed Rainbow closer towards the edge. She could feel her own hips twitch against her muzzle as she got closer with each lick. 

Then she hit a really sensitive nerve with her tongue making Rainbow moan deeply. Her moan vibrated her body accentuating the pleasure pushing her over the edge. 

She did her best to get as much of her marecum and her Mistress’s cum as she could. Drinking all she could as she was forced to close her eyes so she didn’t get her cum in her eyes. She let the orgasm take over as she rode the waves of release. Her hips thrusting weakly against her muzzle with each subsequent wave. Her hind legs twitched madly through her orgasm.

But eventually her orgasm stopped letting her lower her neck back to the mat. She was panting heavily as fluid dripped from her marehood landed on her muzzle. Swallowing down the reminding marecum in her mouth Dash lowered her hindquarters so she was laying flat on her back again. Rainbow found herself looking at her reflection, her muzzle was covered with her own cum and bits of Twilight’s. Her mane was even more of a mess now too. 

She looked even more like a worthless slut now. To Rainbow the look suited her. It also lit the urge to go again, to make herself cum again but she had to obey her Mistress and get cleaned up.

So she did. 

She moved into the shower and started the water making sure the nob was on hot. Then she waited briefly to make sure it was actually hot checking the water with her hoof. When the water was indeed hot she entered the shower. The hot water landing on her back and soaking her coat. She turned herself making sure to get the water all over herself.

She then picked up a bottle that was some shampoo brand she didn’t know the name of with her wing. Put the shampoo in her fur and started spreading it with her hooves. Rainbow had so much going through her head that all seemed to cancel out to one feeling she had, happiness. She realized she had been wearing a smile this entire time, but how could she not? Her sexual fantasies were being made a reality.

She washed herself off and cleaned up like Twilight told her to. Drying off she returned to the bedroom and waited for Twilight. She wouldn’t need to wait long.
> Chapter 3
> --------------------------------------------------------------------------

Rainbow heard the sound of Twilight walking in the bedroom behind her. She turned to look at the lavender alicorn. Her eyes locked on the huge shaft bobbing underneath the alicorn. Rainbow knew Twilight had to be big but how big she was blew her away. The alicorn’s cock was above three feet long, maybe three feet and eight inches in length. The shaft had to be at least three and a half inches in diameter then ended at four.

The marecock was so long that the head of the shaft was poking between the alicorn’s front legs and was smearing precum onto her lavender fur whenever the head brushed against her legs. The cock was dripping precum at a steady rate leaving a trail of precum on the floor behind her as she walked farther into the bedroom. 

Rainbow realized she had that monster of a cock deep in her pussy not too long ago. It had stretched her wide open and claimed her by filling her with cum. She couldn’t help but moan as she quickly felt a heat start to burn her in nethers. The cock radiated this aura of dominance that made her open the hind legs as Twilight got closer to her. 

The alicorn walked towards her putting one hoof directly in front of the other making her monster shaft sway left to right. With each step she purposely brushed her shaft against her forelegs. Rainbow couldn’t take her eyes off Twilight even if she wanted to.

Twilight smiled seductively “You like what you see, Dashie?” The alicorn said as she slowly approached the mesmerized cyan pegasus. 

“I-I do Mistress.” Rainbow watched as the dominant alicorn got closer to her. The submissive pegasus already felt her arousal trickle down her inner thigh. She was already wet and Twilight hadn’t even touched her yet. 

Twilight called her out on this. “You're already wet?” Twilight got close enough to brush coats with her pet, lavender and cyan fur mixing. Rainbow’s hind legs were shivering and twitching. Her wings twitched as they slowly flared out with arousal. Her tail was off to the side leaving her pussy exposed to the alicorn. 

The alicorn extended a wing and traced a feather around her pet’s opening getting a gasp from the mare. The feather got closer and closer, almost brushing her clit. But the feather didn’t touch the nerve making Rainbow whimper needly. 

Instead the feather was put back at the beginning starting the slow process of circling the pegasus’s nethers all over again. Now Rainbow had trouble staying standing as she was dripping wet and her hind legs felt more like rubber with each pass of the feather. Then the alicorn whispered in her ear. “Look at you melting into my hooves.” 

“Mmmmmf” Rainbow moaned as she was trying to stay standing under her Mistress’s teasing.

Then Twilight bit the side of Rainbow’s neck hoping for it to hurt a small bit. Rainbow loved the pain moaning out “hhhgggggh” leading Twilight to bite harder and start to roll the skin in her mouth. 

Then Dash moaned out “H-harder...” and raised a foreleg to press on the alicorn’s head.

Twilight stopped her bite immediately and before Rainbow could react, Twilight grabbed her head in lavender magic and forced Dash to look at her. “Did you just try to force me to do something?” Twilight accused.

“I-I” Was all Rainbow managed to stammer out. 

Twilight used her magic to take hold of one Rainbow’s wings and spread the limb open, fanning out the feathers. She was holding Dash’s million bit limb in her gasp, under normal circumstances Rainbow would throw a fit. As she spent countless hours training her muscles to be strong. She spent just as much time making sure her feathers were just right and cleaned properly. However Rainbow didn’t fight her in the slightest. Leading Twilight to wrap her magic around one of the less important feathers. 

She looked at the pegasus waiting for the signal. 

Rainbow flapped her right ear three times.

Twilight felt a shiver go down her back as she pulled out the cyan feather. In response Rainbow made a sound that was a mix of a moan, a whimper of pain and what had to be joy. The sound was beautiful, it was one of a kind making the alicorn let out a much quieter moan of her own. 

“Thank y-you Mistress for punishing m-me.” Rainbow panted out between breaths. 

“Your welcome slut. If you want something you have to beg for it like a pet or the slut you are, understand?”

“Y-yes Mistress.” 

Twilight used her wing to push her pet’s hind quarters down to the floor so she was sitting on her rump with her own body following the cyan mares. When they reached the floor Twilight moved her muzzle to whisper in the submissive pegasus’s ear. 

“When I use you I want you to let every sound out. Don’t muffle a single moan or word.” Twilight moved to sit behind the pegasus with her alicorn shaft resting on Dash’s back. “I want to hear your desperate pleas for more as I treat you like a fuck toy.” While saying this she lowered her right forehoof and started slowly playing with Dash’s wet marehood. 

“The sounds you make Dashie are music to me and I'm going to use you to make more of them, many more.” Twilight licked her pet’s ear as she did so.

“Mmmmmmf... I want you to use my body.” Rainbow responded as the alicorn played with her folds. She could feel her Mistress’s shaft flexing against her back and dirting her cyan coat with warm precum. 

“Good girl….You know what’s going to happen?” Twilight whispered as she threaded her left forehoof and rubbed the submissive pegasus’s chest.

“T-Tell me.” Rainbow responded as Twilight’s hoof pushed its tip into her wet folds spreading her open. With the way Twilight was holding Dash made the pegasus feel small with the alicorn over shadowing her. Twilight had unhindered access to her body in this position making Rainbow moan at the control the alicorn had over her.  

“When I know the spell I’m going to give you a cock.” Twilight whispered hotly into the pegasus’s ear. Rainbow melted in Twilight’s hooves quickly leaning back into her Mistress moaning “Change me please…..You own me.” 

“I’m going to make it two feet long. Long enough to be the perfect tool for breeding and breaking in other mares.” Twilight’s hoof got more aggressive with her pet’s marehood as both mares closed their eyes indulging in the fun that was to come.

“You would be like a wild dog as you thrusted deep in there pussy.” Twilight whispered hotly to Dash’s ear. “You would make them moan and beg for more. Just like you begged for me. Then you would cum deep inside the mare, fire load after load of seed, filling her up.” Rainbow was nodding she wanted it. 

“Once you filled her up with your cum pet. Your going to fuck them again, harder. Your going to pin them down and fuck there pussy raw.” Rainbow nodded moaning. 

“Would you watch me fuck them?” Rainbow whimpered out the question.  

“Every time.” Twilight felt Rainbow start to shake in her hooves, her hips bucking against the lavender hoof. Rainbow was close to her orgasm as her wings flared out, her back arched and her free hoofs tried to find something to hold to. “So close…. ahh…..Mistress.” 

Twilight moaned deeply in Rainbow’s ear. The way Dash writhed against her as she quickly approached orgasm felt empowering. She was making Rainbow squirm and shake. She was making her gasp and moan in pleasure. She could feel the mare’s breathing get faster and faster. Twilight could feel her own arousal soaking her thighs. The alicorn subconsciously rubbed her shaft against her pet’s back getting her cyan fur covered in precum. 

Rainbow moaned at the thought of breeding another pet. Her cock being buried in some mare’s hot depths. The other pet’s body milking her, hungry for her seed. Filling them up and listening to them beg for more as she bred them again and again. All while Twilight watched her.

“I’m going to cum Mistress!” Rainbow yelled as she passed the point of holding back. “Cum for me, slut.” Twilight commanded directly into the ear of Rainbow. So she did her mare cum squirting out of her as she moaned. “Thank you…Thank you.” 

As soon as she felt Rainbow cum Twilight attacked her pet’s clit using her hoof saying, “That’s it cum, cum like a good slut. Keep cumming for your Mistress.” Twilight encouraged her pet. Thanks to the hoof of her Mistress and the way she encouraged her to cum like the slut she was, Rainbow kept cumming. 

“I’m cumming…. for you… Twilight.” Rainbow moaned as her hips spasmed wildly as her orgasm rolled through her body. “That’s it cum for me.” Twilight whispered as Rainbow rode out the extended orgasm. 

Soon the orgasm started to end slowly for Rainbow. Twilight changed her hoof to slowly and gently play with her pet’s folds. 

“Thank you…. Mistress.” Rainbow muttered as the haze of orgasm started slowly receding in the pegasus’s mind. Rainbow’s breathing slowed as she opened her eyes. Her marecum was all over the floor in front of her making a long puddle. She moaned again as Twilight kept playing with her pussy just at a slower and relaxed pace. 

Twilight twisted her hoof against her pet’s marehood to get a “mmmfffff” from the pegasus. She then slowed her lavender hoof to a stop and removed her hoof from the soaked marehood of the pegasus. She then turned Rainbow’s body to look at her.  Twilight’s cock throbbed as Rainbow looked at it. 

Twilight extended one of her wings and partially covered her marecock from Rainbow. “Hold out your front hooves. I have a gift for you.” 

Dash held out her front legs as instructed to but couldn’t help but want to service Twilight’s shaft. “A present?”

Twilight nodded her horn flashing briefly. Rainbow gasped, the idea of Twilight’s cock temporarily being forgotten. In her front hooves was a pet collar. It was a lavender colored piece of fabric that was enchanted. It had a latch on one side that would open so the collar could be put on with ease. The front of the collar had a metal loop. The loop held a small six pointed lavender star that was attached to the loop. It was clearly Twilight’s cutie mark to anypony who looked at it. 

The words “Property of Princess Twilight Sparkle” was written on the back of the star. 

Rainbow was silent as she held the collar in her cyan hooves. After a moment tears started to form in the cyan mare’s magenta eyes. She gave the collar back to Twilight who was about to say something. But Dash spoke first with a deep blush on her muzzle “M-Mistress’s p-put collars on their pet’s.” Twilight smiled as she opened the collar.

Then latched it closed around Rainbow’s neck with a click. 

Rainbow lunged forward and kissed Twilight deeply. With the alicorn being surprised briefly before she started to meet the kiss head on. This kiss was made out of love rather than lust. Something formed as both of the mare’s tongues intertwined, something that had always been there just not known. But now both mares had found not just lust but love too. 

Twilight lifted her hoof and wrapped it around the back of Dash’s head holding her in the kiss. Rainbow moaned at the feeling of Twilight’s hoof. She felt Twilight take over the kiss with the alicorn’s tongue dragging and pushing it around. The kiss could have lasted days for all the two mares cared as the kiss lasted a long time.

Eventually the kiss ended with both mares panting, smiling and looking at each other. Rainbow spoke first “I l-love you Twilight.”

“I love you too Rainbow.”

A happy silence filled the air till Rainbow broke it.

“T-Thanks Twilight the collar means a lot to me, it’s almost overwhelming.” Rainbow said blushing as she nuzzled Twilight. Her fantasies were now reality, she had Twilight as her Mistress. She was wearing a pet collar from Twilight. 

“Tell me what the collar means to you Rainbow.” Twilight said.

A shiver went down Rainbow’s back. “The collar shows to anypony who looks at me that I belong to you. That I’m your property, my body, pussy and w-wings are yours to use and the collar means you're allowed to use me whenever you want or however you want. That I trust you to hurt me and more.” Rainbow was quiet for a second.

“I’m not going to take it off.” Rainbow stated. “I don’t care who sees it.” She wanted everypony to know Twilight Sparkle owned her and she was already claimed. That her body was somepony’s else’s.

“That’s up to you Rainbow.” Twilight said with a giggle “just so you know it’s enchanted so nopony sees it unless you want them to. Except me I can see it all the time.” Rainbow nodded.

“Now before we get too much into being Mistress and pet. Let’s discuss the living situation.” Twilight said.

“Is it ok if I live here in the castle. I have got really nothing holding me in my cloud house.” Rainbow said hopefully looking at Twilight. 

“Yes that’s fine, just don’t sell your house yet Dashie. We might need it at some point.” Twilight answered “But Rainbow” Twilight continued “if you're going to live here to fulfill your submissiveness I need something from you.”

Rainbow nodded “Anything.”

“I want you to be able to take my whole cock.” Twilight stated.

Rainbow nodded “I want that as much as you do. But how?” 

“There’s a spell I can use.” Twilight said. 

“Will it affect me flying?” Rainbow asked her only concern. 

“No not at all. But it will feel painful as I make your tunnel deeper.” Rainbow smiled “it better, I love being forced open and stretched. The pain feels so awesome. Is... Is there a way to make it so my pussy needs to be forced open again each time you use me? I want to stay tight so I can feel you better.” 

Twilight thought for a moment then nodded. “I can make it so you tighten on command and stay tight. But just know I love to show off my work.” Twilight pecked Rainbow on the lips. “And you're going to be my best work. I'm going to constantly improve you and show you off.”

“I have no problem with that. But how soon can you change me?” Rainbow asked. “I can do it now if you want.” Twilight answered with a smile. 

Rainbow nodded.

“But first” Twilight kissed her pet briefly then roughly pushed Rainbow backwards so she would lose her balance. She did and landed on her back with her wings spread out on the floor. 

Rainbow watched as Twilight moved to stand above her. Mistress’s cock throbbed as Twilight loomed over her showing just how big she really was. Precum leaked from the head and landed on her chest. The alicorn smiled as she moved forward to have her marehood above Rainbow’s face. Twilight lowered herself to Rainbow’s muzzle. 

Twilight moaned as her pet’s tongue started exploring her entrance. The tongue was quick and enthusiastic going as deep as it could. As Rainbow gathered as much of her Mistress’s fluid as she could reach. “Good slut….. mmmmmf… you love how I taste don’t you?” Twilight asked, getting a hum of yes from the slut she owned beneath her. Twilight started grinding her hips against her pet’s muzzle. 

She then used magic to take one of Rainbow’s hooves and moved it to the cyan mare’s own entrance.  “Hoof yourself pet.” Twilight commanded just before a moan left her mouth. Twilight brought her wing to her cock and started stroking herself. The alicorn fell in a steady rhythm of grinding herself on Rainbow’s muzzle and stroking her alicorn shaft. 

Twilight was reveling in her sense of control, she had complete consensual control over Rainbow. Making the whole thing so much hotter. The alicorn was determined to make Rainbow the perfect pet. But in order to do that she was going to have to talk to Cadence. But that would be after reshaping her pet’s pussy.

She felt she was going to cum soon. Twilight removed her wing and focused on her hips, grinding harder against her pet. Then started bucking her hips trying to force more of her pet’s tongue in her pussy. 

“Get ready slut I’m going to cum and I don’t want a single drop wasted.” Twilight ordered as Rainbow moaned. 

Twilight moaned as she reached orgasm. Pleasure rolled through her like a gentle wave making her smile. It wasn’t some massive spike in pleasure that made you melt into a cumming mess, something she was going to do to Rainbow every chance she could, but a calm feeling of lightness. She moaned hotly though from blocking her cock from cumming, she had used magic to stop her shaft’s orgasm. Her hips twitching as if she was firing loads of cum. 

Rainbow swallowed every bit of her Mistress’s marecum with hunger, desperate to get every last drop. Rainbow forgot about her hoof as she tasted more of Twilight’s juices. She loved the taste but she was left wanting more as Twilight stopped cumming. Then she got up and moved to the bed but didn’t get on the bed. 

“Get up on the bed.” Twilight said as she casted the spell on Rainbow’s marehood.
> Chapter 4
> --------------------------------------------------------------------------

“Mistress what position do you want me to be in?” Rainbow asked as she got on Twilight’s bed with the alicorn following her. Rainbow could feel the spell Twilight placed on her. It tingled her nethers slightly giving her this warm pleasurable feeling. 

Twilight answered her pet’s question by using her magic to push Rainbow on to her left side. Then she laid on the same side next to Dash her alicorn body overshadowing the pegasus. Rainbow surrendered her body to Twilight as she held up her pet’s right hind leg with her own hind leg by wrapping her hind right leg around Rainbows. This left the cute pegasus exposed as Twilight moved one of her forehoofs to rub at Rainbow’s clit. While her Mistress’s marebreaker of a cock rubbed her dripping entrance.

Thanks to Twilight being bigger than Rainbow she had enough room to place her head next to Rainbow's head and be able to move to look her in the eyes.“This position, I want us to be able to watch as my cock goes in your pussy and play with your clit.” 

Rainbow shuddered as the tip of her Mistress’s cock rubbed her opening the shaft was huge compared to her small frame. “Please Mistress change me.” 

Twilight asked a simple question “How rough?” 

“As rough as you can Mistress, please make it hurt.” Rainbow’s hips twitched eager to envelop the monster marecock of Twilight. 

Twilight removed her hoof from her pet’s clit and looped it around her chest holding her in her forelegs. “Let me know if it becomes too much to handle.”

“Got it.”

Twilight nodded and let her earth pony strength take charge as she pulled her alicorn cock back a small bit. Then she thrusted forward. Rainbow threw her head back and moaned deeply in bliss. “Yess!” Almost a foot had entered right into her wet tunnel with ease sending pleasure through her thin fame. 

With how Rainbow responded Twilight kept pushing her hips forward. She was making sure to not give her pet time to adjust to her size as she pushed herself deeper. She tightened her grip on Rainbow instinctively making sure to keep her close. The alicorn then whispered hotly into Dash’s ear. “I’m already a third of the way there pet.”

Twilight extended a wing and placed a feather under the pegasus’s chin. The alicorn used the feather to turn her pet’s head to face herself as she moaned. “Mmmmmhhhhhffff All… I need it all, please.”

Twilight smiled lustfully looking into Dash’s magenta eyes. The pegasus had a look of desperation and fulfillment. “Don’t worry you’re going to take it all. I’m going to make you into the perfect cock sleeve.”  

Rainbow nodded moaning as more inches of Twilight’s cock pushed into her. “Make…. me…. The perfect... slut Mistress.” Her Mistress was forcing her open inch by glorious inch. The feeling of each inch of the cock going in deeper and deeper into her wet depths was amazing. Her body being forced to open itself up for the mare who owned her was a feeling unlike any other. A feeling she loved. 

Rainbow could feel her orgasm coming soon.

Twilight kissed Rainbow playing with her tongue. Rainbow moaned into the kiss but stopped when she felt Twilight’s cock hit the entrance to her womb. She let out a whimper. “Twi… it’s not… all in.” Rainbow looked almost hurt as desperation and sadness filled her eyes. 

Twilight smiled back at her warmly as she pulled herself back a few inches, her cock slipping out a few inches out of the hot vice that was her pet’s pussy. Twilight let her earth pony strength flood her once again and brutally thrusted her marecock against Rainbow’s inner barrier. 

For which she was rewarded with the beautiful sound of her Dashie screaming her name. “Twilight!” Rainbow felt a wonderful sting of pain with plenty of pleasure included as well. The pegasus felt fuller than before her Mistress’s last thrust. “Don’t stop Twilight… please don’t… stop.” Rainbow begged looking and sounding just as desperate as before if not more so. 

“You're such a slut.” Twilight answered with a thrust of her hips getting a yelp of pleasure from Dash. “D-degrade m-me.” Rainbow whimpered out as she felt more of her Mistress’s marecock.

Twilight smiled “You love being demeaned by those you trust don’t you?” It was less of a question and more of a statement. To which Rainbow only nodded moaning. “Only Mistress.” 

Twilight watched Rainbow moan loudly as each inch entered her cunt giving the alicorn a sense of almost conquest. The alicorn thrusted again getting her marecock another inch deeper in her pet. Each time she thrusted she felt warmth surround parts of her shaft that had never felt the pleasure of a hot marehood. It was like new nerves were being found with each thrust that made Rainbow’s pussy deeper. 

Twilight started thrusting her hips with more force pushing her alicorn cock to go deeper into her pet’s body with each thrust. The dominant alicorn was rewarded with a steady stream of moans from Dash making Twilight moan in turn. 

For Rainbow new nerves were being made with each thrust of her Mistress’s mare breaker. With each thrust of the heavenly marecock Dash could feel her organs move to make room for more of the shaft that owned her. Each thrust hurt beautifully making her squirm in Twilight’s grasp. With each thrust Rainbow felt more full, more complete. 

Twilight turned her head to look at her Pet’s chest “Ooh Rainbow look what you’re letting me do to your body.” Twilight turned Rainbow’s head to look at her chest. 

There was a bulge of her Mistress’s marecock running up her chest. The bulge was easily noticeable to anypony who looked at her. She couldn’t believe there was still more of Twilight’s cock outside of her. Dash still had at least a foot more of marecock to take. 

She watched as the bulge went back down her chest with Mistress pulling back her hips. Then the submissive pegasus watched as the bulge surged forward up her chest going farther up then before. 

The sight made Rainbow cum with a gasp, with her marecum adding to her already soaked thighs.

Twilight moaned at the feeling of Rainbow’s pussy walls tightening around her, trying to milk her cum out of her. Twilight had to hold back her own orgasm. Seeing her cock bulge through Rainbow’s chest was almost ethereal. She could physically see the impact she was having on Dash’s body, see how deep her cock was in her. See her flesh lift up as she pushes forward. 

The best part?, this mare was hers. Rainbow was her pet, her body was her’s to use as she saw fit. That idea alone turned her on to no end.

Twilight whispered hotly in her pet’s ear “That’s it slut, cum.” as Rainbow experienced the waves of her orgasm. The alicorn didn’t give Rainbow a moment of respite as she came; she kept her place the same. But making sure to thrust mercilessly into her pet. 

“It hurts…it hurts so good... I love it.” Rainbow moaned out as she came with each word sounding like music to Twilight’s ears. Rainbow’s begging and moaning made it even harder to hold back her own orgasm. The way her body was twitching and squirming in her grasp, the alicorn could feel Rainbow’s right hind leg twitching wildly against her’s. It had enough force behind it that Twilight couldn’t hold it still if she wanted to, not that she did.

Not to mention the orgasm she had denied herself when Rainbow ate her pussy out. But she could hold back for hours if she needed to, besides she loved the burn being denied brought her as it added to her constant arousal wonderfully. 

As Rainbow’s orgasm ended Twilight lifted a fore leg and pressed her lavender hoof over the bulge that was going up Rainbow’s chest. “You love how you’re changing your body for me, don’t you.” 

“Mmhum.” Rainbow moaned as she looked at where Twilight was touching. 

“Y-yea I love being a-a s-slut for y-you Twilight.” Each word she said left her mouth heated and filled with lust as she started thrusting her hips back in rhythm with Twilights. Each thrust brought both of the mares closer to the goal they both desperately needed to achieve. 

One of Rainbow’s fore hooves touched her new pet collar. “I love…. being y-your toy… your p-pet… gggaaaaahhhhh… you’re changing me to….. a-a better pet. You're going to… t-train me… hhhhggggg… take control… l-l love y-you.” Rainbow said with lust dripping from her words. 

Twilight moaned deeply at Rainbow’s words. “I love you too Rainbow.” 

Twilight’s thrusting was stopped by her medial ring having trouble entering Dash. Rainbow grit her teeth as pain exploded at her wet entrance. The ring was at least an inch and a half bigger than the rest of her Mistress’s shaft. She felt tears come to her eyes as she pushed back as hard as she could against the ring.

Dash’s muzzle wore a joyful smile as the pain became more intense the harder she pushed. She clenched her pussy as tight as she could, squeezing down Twilight’s cock. As she had tears from the pain, she moaned in bliss. “Yes...Twilight yes!...it’s so good!” 

Twilight smiled the sight of seeing her pet actively cause herself pain, it was super arousing to her for some reason. “You really love pain don’t you slut?” she said as she started pushing her marecock harder against her slut’s entrance. 

“Yes M-Mistress!” Rainbow shouted as she trembled in her lover’s grasp.

Rainbow started panting like a desperate slut as Mistress pushed harder against her entrance. She loved the pain of her soaked folds being very slowly forced open by the medial ring of her Mistress’s alicorn cock. It was heavenly how it was painfully grinding against her opening. 

The delightful grinding lasted a minute before Rainbow heard the sound of a needy whimper leave Twilight’s throat. Which then quickly turned into a growl that sent shivers down Rainbow’s body. The growl was predatory sounding, like a wolf that was ready to attack.

Rainbow felt Twilight pull her hips back, pulling out a large amount of her mare breaker of a cock, almost a foot. Dash moaned feeling the inches of cock pull out of her; it gave her this empty feeling. She felt Twilight push her trapped wing under her and wrap around her chest with her free one doing the same. The alicorn’s hooves wrapped around her upper body holding her tightly. With each way Twilight held her in place Rainbow felt her anticipation rise as she tried to thrust her hips back but to no avail. 

Rainbow was about to turn her head to look at Twilight but felt her hot breath on her ear. The breath was filled with this hungry lust that made Dash moan. Twilight whispered in her ear, “Scream for me.”

“Twilight!”

Rainbow did, she let out a scream that hurt her voice as her head flew back and her eyes rolled into the back of her head. The sound was forced out of her as Twilight savagely thrusted her hips forward. The alicorn’s medial ring was forced in with the full strength of an alicorn giving Rainbow the best pain she had ever felt. So much that she started cumming immediately.

Rainbow felt the entire marecock surge deeper into its new home, her body. Dash looked down at her marehood and watched as inches of her Mistress’s massive shaft disappear in the pussy. Each inch showing in the bulge that even showed through her Mistress’s wings. She felt her organs move as her body stretched with each inch Twilight relentlessly forced in her smaller body. 

Pain and pleasure were one in the same as they racked her senses. Her body kicked weakly against the alicorn’s stronger body as Twilight held her tight moaning into the submissive pegasus’s ear. “You’re mine.” 

“I’m yours!” Rainbow shrieked back as her orgasm continued to rage throughout her body. She felt Twilight push her muzzle with her magic and made sure she watched as… as...

Rainbow felt Twilight’s hips hit hers. 

All of Twilight’s cock was in her body. 

Both mares screamed in ecstasy as Twilight’s cock flared. Rainbow turned to look into Twilight’s eyes and found them looking back at her. 

“Cum for me Mistress.” 

Twilight growled as her alicorn cock flexed. 

Twilight's hips locked forward as she pushed Rainbow down as the first load of her hot cum was released filling Rainbow. “Take it, pet.” 

Rainbow felt herself have another orgasm right on top of her first one. “Fill me.”

Twilight used her magic to push Rainbow into a deep kiss as she pumped her hot seed into Rainbow’s thin athletic body. Rainbow moaned into the kiss as she felt the alicorn fill her pussy with load after load of hot cum. With each batch her own orgasm lasted longer, as if her Mistress was keeping her cumming.

Rainbow’s mind was in a fog of bliss as she continued to submit to the alicorn. Rainbow didn’t want it to end with the way her Mistress’s shaft twitched in her body as she came. 

But eventually it had to end as her orgasm ended after she felt the cum stop. But the cock stayed hard keeping her reshaped pussy full. They broke the kiss panting and looking into each other’s eyes. “Thank….. you…… Mistress Twilight.” Rainbow moaned.

“You’re welcome my pet slut.” Twilight answered with an impish smirk. 

“Don’t pull out, please. You feel so good.” Dash whimpered. 

Twilight responded by turning Rainbow’s body to face hers so they were chest to chest. All while being careful not to let her cock slip even an inch out of her pet’s pussy. She even wrapped her right hind leg around one of Dash’s.

“You’re such a good pet slut Rainbow.” Dash moaned at the complement. 

“What if I were to find torture spells?” Twilight asked.

“T-Torture Sp-Spells?” Rainbow asked with anticipation. 

“Mmhum, one’s that I could use on a masochist like you and make you scream.”

“I’d love that Twilight it sounds awesome.” Dash answered.

“Good, But You look exhausted, pet.” Twilight said as she wrapped her body around her little pegasus. 

Rainbow was exhausted; she felt like she had flown to Canterlot and back ten times. Dash wrapped her legs around Twilight saying with a blush. “Use my body while I sleep. Please.” 

Twilight’s hips started to very slowly rock back and forth. Rainbow moaned at the rhythmic movement. “T-Thank you.” 

Twilight half giggled and half moaned. “Don’t worry Dashie I will use you every chance I get. Anytime I want and anywhere.” Twilight lifted a hoof to start petting Rainbow’s mane. Getting a hum of comfort from her pegasus as she snuggled up to her.

Twilight used her magic to lift a blanket to cover both of them. Within seconds Rainbow passed out for the night.
> Chapter 5
> --------------------------------------------------------------------------

Rainbow woke up feeling unbelievably cozy. Hooves were wrapped around her body holding her close. She could feel wings wrapped around her back as her chest pressed softly against Twilight’s chest. 

But most of all she felt Twilight’s cock slowly shifting inside of her body as the alicorn’s body seemed to be instinctively thrusting into her. It was extremely slow. But it wasn’t just that Twilight was unconsciously fucking her that made this so hot. 

It was definitely the idea that she was being a perfect living cock sleeve for Twilight. The idea made her moan. She was keeping Twilight’s alicorn cock warm and wet. She was acting as a cum dump for her Mistress. Even as she was asleep.

Twilight’s marecock also gave the pegasus this feeling of comfort as she felt this perverse warmth being provided by the shaft as it throbbed and moved. With each throb Dash felt a small amount of hot cum leak out of the shaft and into her depths. 
She could also feel Twilight's heartbeat throughout her small frame thanks to her marecock. 

Many of the submissive pegasus’s fetishes were being fulfilled. The whole situation was a dream come true for her. Thankfully she had finished this year’s tour with the 
Wonderbolts. So she didn’t have to choose this dream or her other dream. While most likely they will figure something out by the time next year’s tour happens. 

A moan slipped out of her mouth as she felt the alicorn’s hips press against her. The shaft fully sheathed in her once again. Rainbow still had trouble believing that almost four feet of marecock was in her body. She realized that the alicorn must’ve snuck in another spell that somehow kept her body from being too filled with cum. Something she was thankful for.

But she most definitely felt full with her Mistress’s hot warm cum. Rainbow moaned at that thought. She had spent the whole night filled with both Twilight’s cock and her cum. 

She wanted to run her hoof along her chest to feel the bulge that was running up her body thanks to Twilight. But that would mean moving a hoof off of Twilight and she couldn’t bring herself to do that. Nor could she move her head to at least look at her chest with Twilight’s head using her neck as a pillow. 

Rainbow let out a moan as a thought crossed her mind. What if Twilight was biting her neck? Right on her throat and stopping her from b- Rainbow’s thoughts were stopped as she felt something poke her cheek. She tilted her head to see Twilight’s horn directly in front of her muzzle.

Rainbow wasn’t going to lie Twilight’s horn was attractive in the same way her own wings were attractive. A long well kept horn was like a strong pair of well kept wings. Rainbow remembered hearing that a unicorn's horn was sensitive. She remembered imagining what would happen if she licked or even more sucked her friend’s, now Mistress’s, horn. The pegasus had fantasized about being able to make her orgasm from sucking horn alone or making her cum from the perfect preening. 

Rainbow knew that she had to learn how to make Twilight Sparkle cum from a horn job alone. She wanted to be the perfect pet for Twilight after all. 

Without thinking she opened her muzzle and took a lick along the alicorn’s horn. She got a moan from the lavender mare’s muzzle. Feeling encouraged she continued, opening her mouth and wrapping her lips around the tip. Getting another moan from Twilight. Rainbow smiled as she pushed herself down slowly taking her Mistress’s horn in her muzzle.

Twilight’s horn didn’t really have a taste like one would find if they were sucking a cock or eating out a pussy, but licking a horn was not really about the taste. Nor did it give you something back for your efforts like hot cum to drink or sticky marecum to swallow. Sucking somepony’s horn was much more about the act.

It was about either being so dominant that you sucked your partner’s horn off while they were ‘helpless’ to do anything. Or being a good pet that would suck off their Mistress and love that they get nothing in return. Or even being so well trained that they could make their Mistress cum hard from her tongue work alone. 

A shiver went down Rainbow’s back. T-t-then maybe Twilight would make her pet ride her horn. Rainbow moaned deeply as she reached halfway down Twilight’s horn. Then as soon as Rainbow passed that point felt more of her Mistress’s cum leak into her pussy making Dash moan hotly. 

Unseen to Rainbow Twilight’s eyes were open and she was awake. She had woken up as soon as her pet’s lips touched her horn. 

This was by far the best way she had ever woken up. Her cock fully sheathed in a hot, tight tunnel and feeling her pet’s mouth suck her horn was dream-like. Twilight moaned as she felt Dash push herself to her horn’s base. 

Rainbow pulled back dragging her tongue along the side of her Mistress’s horn, up to the tip where she sucked lightly. Once again getting a hum of pleasure from the alicorn. 

Twilight was impressed with Rainbow’s horn job, she had some idea of what she was doing. But Twilight knew she could train her to do better, much better. 

But not today as she wanted to get a shower for her and her pet. Then do some searching through her books to find spells she could use. Namely a spell to give Rainbow a cock like hers and the ‘torture’ spells. But she also wanted to take Rainbow on a walk either through the castle or the outskirts of town. Twilight had a leash and she wanted to use it. 

Besides she knew Rainbow was an exhibitionist just like her. She wanted to show off her pet and the idea of fucking her pet in front of there friends was extremely appealing. Or forcibly putting her hoof to Rainbow’s pussy and if she could find the spell, wrap her hoof around Rainbow’s cock. Then making the cute pegasus cum in public. 

Twilight smiled with her basic plan decided. 

She then spoke. “Not bad Dash.” 

Understandably Rainbow was startled into freezing her movements as she was half way down the horn. 

Twilight had to fight the urge to tell Rainbow to keep going and finish her horn job. So the alicorn gently pulled her head away from Rainbow’s mouth moaning as she did so. 

Rainbow stayed frozen in place watching Twilight move her head. “I’m s-sorry.” 

Twilight looked up at her “No don’t be. I liked it, Dash. You just need training and practice.” 

Dash nodded and calmed her nerves down. She then asked “Are you gonna pull out?” Rainbow’s hips twitched involuntarily at the thought of her Mistress’s shaft. 

Twilight nodded. “Have to if we want to get anything done. But don’t worry” Twilight gave Rainbow a light thrust then started grinding her hips against Rainbow’s hip, swirling her cock in the mare’s cock sleeve. The submissive pegasus moaned as she started to do the same back to Twilight. “I’m going to put my cock where it belongs every time I sleep now.” 

“I’d love that.” Rainbow answered almost dreamily. Twilight giggled quietly “Of course you would. Now we’re going to get cleaned off in the shower, although I doubt staying clean will last long. Then we’re getting food from the kitchen after which we will head to my library. Got it?” 

“Got it.” Rainbow responded. 

Twilight started pulling her cock out of it’s new wet home. Making both mares moan as the alicorn rod left the hot, tight confines of her pet’s pussy. Rainbow let out a whimper as Twilight got up untangling herself from Rainbow. 

Twilight turned back to look at Dash “Come on Dashie lets get you cleared up.”  

Rainbow nodded as she got up and followed Twilight in to the bathroom. Her eyes were unable to leave the alicorn’s body as she wasn’t hiding anything from her. It was like Twilight was trying to show off herself. 

As Twilight walked forward she swayed back-and-forth slightly making it hard to not blindly follow her. Especially with her tail off to the side giving Dash a clear unobstructed view of her Mistress’s lavender marehood. Rainbow wanted to push her muzzle against the opening and push her tongue into Twilight’s warm depths to taste her once again. 

Rainbow heard the sound of running water snapping her out of her trance. She shook her head and looked back at Twilight who had a hoof to her chin in thought. She nodded to herself then looked at Rainbow.  “Let’s save the sex for later as I want to get you clean.” The alicorn pointed a wing at the shower. 

Rainbow walked in the shower without question “Yes Mistress.”





Rainbow wore a bright red blush as she walked down the castle hallway. As now she was not just wearing a collar around her neck but that collar now had a leash attached. One that Twilight was using to guide her around the castle.

The leash was lavender colored just like her collar. The leash was long enough that Twilight could hold the leash in her mouth if she wanted to. Instead she held the object in her lavender magic as she walked next to Rainbow.

“T-Twi?” 

Twilight turned her head to look at the pegasus “Hmm?”

“Thanks for all of this, it's...uh…. liberating and-“

“Dash I’m getting just as much out of this as you are.” Twilight leaned towards Rainbow and nuzzled her cheek. “You're wearing my collar, walking next to me with a leash on that I’m holding.” 

Twilight moved her head to whisper into her pet’s ear. “You’re also letting me use you like a sex slave.” Twilight lit her horn and started to play with Rainbow’s thigh making the pegasus moan out. “I am and I love it Tw- Mistress.” 

A shiver went down the alicorn’s back “Good girl.” 

As Rainbow enjoyed the gentle teasing of her Mistress’s magic. Twilight heard the sound of hoof steps. The hoof steps didn’t belong to herself or her pet as they were coming from the library. Leaving the most likely answer that they belonged to Starlight. 

“Rainbow I think Starlight is in the library already. Do you still want to go in?”

The pegasus nodded her head. “Yea, but... use me please.” Twilight smiled and kissed her pet. Twilight was more than willing too. 

Twilight led Rainbow into the library. The large circular room was currently occupied by a lilac unicorn who was looking through the book shelves. Or at least had been. 

“Uhh.” Starlight was looking at the most bizarre scene she had seen in a long time. 
First was that Twilight was fully exposing herself, with her marecock openly throbbing and slowly dripping cum. Twilight normally used her magic to do something to it so the shaft didn’t get in the way. Second Rainbow was wearing a collar with Twilight’s cutie mark dangling from the collar. Then there was also a leash hanging in the alicorn’s magic that connected to the collar. 

“Oh.” A smile formed on the unicorn’s muzzle. The unicorn wouldn’t have guessed that Rainbow was the submissive type. Regardless, Starlight was happy to get some potential action today, besides she had nothing to do today. She put down the book that was in her magic and met the mare’s halfway. 

Starlight pointed at Rainbow with a hoof while asking Twilight. “Is she yours?” 

Twilight smiled back to Starlight then looked at Rainbow. She placed a hoof under the cyan mare’s chin. “Yes Starlight, this little mare is mine. I have claimed her.” Twilight wrapped a wing around her pet and pulled her closer. Then gave Rainbow a quick kiss. “I claimed her by filling her up with my cum.” 

Starlight let out an slightly aroused giggle. “I bet you did, Twilight.” Starlight stepped closer to the pair. “I have to ask, did she take more of that monster cock than I did?” 

Rainbow tilted her head when Starlight spoke. “What?” 

Twilight answered her lover's question “I have had fun with Starlight and others on occasion. You're not the first mare I've fucked. I hope you’re ok with that.” Dash nodded.

“Are we in an open relationship?” Rainbow asked “Because I would kinda really like that.” 

Twilight nuzzled Rainbow “As long as you come back to me each night, I don’t care.” Twilight looked back at the unicorn “But to answer your question Starlight yes she did.” 

“Wow that’s impressive.” Starlight said impressed, then the unicorn gained an impish smile. “So you are willing to share?”

Twilight looked at her pet and before the alicorn could ask the question Rainbow gave Twilight the go ahead. 

“She’s a slut so she would love to be shared for now. Just know she is mine.” Twilight stated as she guided Rainbow to the middle of the library with the leash. The alicorn stayed where she was as she used her magic to guide her pet.

“However, Starlight but I need your help first.” Twilight said as she pushed Rainbow on to her back with her magic. 

Starlight raised an eyebrow at the alicorn “With what?” The unicorn wanted to get down to using Twilight’s pet. Starlight’s arousal was rising quickly, especially with Dash exposing herself so shamelessly in the middle of the room. 

“I want to give her a cock like mine.” Twilight stated as she pushed Rainbow’s forehoof against her own marehood. The alicorn briefly looked at the submissive pegasus “Play with yourself for us.” 

“Yes Mistress.” Rainbow laid on her back and thanks to her Mistress’s commands the pegasus started to slowly spread out her legs. Revealing her wet pussy to both mares. She then spread her wings out from her arousal. Dash moaned as she started rubbing her hoof against the wet folds of her slit. 

Twilight continued talking to Starlight like Rainbow wasn’t getting herself off in front of the two of them. “But I can’t just use the basic spell as I want to be able to modify the cock I give her as I see fit.” 

“I’m assuming you want your pet’s shaft to be just as,” Glimmer waved a hoof looking for the right word. “Leaky?” 

Twilight half nodded. “Something similar to my own.”  

The lilac unicorn nodded, turning to look at the bookshelves. “I expect to get some action myself.” 

As Starlight turned around to walk to one of the book shelves Twilight could see the unicorn had started to use her magic on her marehood teasing herself slightly. The alicorn grinned as she used her own magic and gave Starlight an arcane rub along her folds. 

The unicorn gasped as she felt Twilight’s magic rub her now moist nethers. Twilight spoke “Don’t worry you will.” Twilight went to go look through the bookshelves on the other side of the room.

Glimmer was a breath away from striking back with her own magic but she knew that would simply make the alicorn more aggressive with her magic. If it had been Trixie on the other hoof she would have easily struck back. 

Rainbow let out a moan as she pushed her hoof against her outer folds. “...Yeah…” She was loving this whole situation. She was masturbating in the middle of the castle library. With both her Mistress and Starlight watching her. 

Her back arched as she accidentally brushed her cilt with her cyan hoof. Sending a particularly strong spike of pleasure up her spine. Dash let out a huff of air as she fought to keep her orgasm far away. When her body relaxed she realized that both doors to the library were currently closed. 

Rainbow blushed hard as she spoke “M-Mistress T-Twilight c-could you please open the doors to the library.” Twilight, holding a book in her magic, looked towards Starlight across the library, silently asking if she was fine with her pet’s request. 

Starlight thought for a moment then nodded with a grin across her muzzle. 

So the alicorn opened the doors to the library with her magic. Giving Rainbow a sight line to the end of the hallway they had walked down and another one down the other  hallway. Twilight knew that the chances of somepony actually walking in those hallways was basically none with both her and Starlight here. But Rainbow didn’t.

Rainbow moaned as she looked down the hallway. “T-T-thank you Mistress.” Dash’s hoof started moving faster as she imagined another pony walking down the hallway and seeing her. Watching her rub her hoof against her soaked pussy shamelessly in the middle of the library. Watching as she obeyed her Mistress’s orders like a good slut. 

Rainbow felt her marehood get touched by her Mistress’s magic aura. “Gaaaahh… yes…” 

Twilight was precise as she used her magic to play with her pet from a distance. She was taking full advantage of Rainbow’s body as she used her magic. Making her squirm and shiver. Twilight was rewarded with Rainbow’s beautiful moans as she used her pet. 

“Yes…. mmmfffff” Rainbow moaned out.

Starlight spoke up “I think I found it.”
