Sweetie Butt

Sweetie Butt

The two foals stared at the strange thing they found discarded out of its box on the floor. The adult products store pony had been run out of town by an unsatisfied contractor who happened to be a dragon, and left his store relatively ransacked, but still with some cool goodies in it. So being enterprising fillies, Sweetie Belle and Apple Bloom had to go check it out. They felt so grown up by the things they found. Stuff that looked like boy penises, stuff that looked like... something that was weirder than a boy penis, but this thing really had them vexed.

It just looked like a stretchy tube of some kind of rubber. A penis... scarf maybe? Or would that be a sock? There didn’t seem to be any function to it, and neither thought to look at the box it came out of for any warning labels, not just from a cursory glance at this thing.

Sweetie Belle looked at it closely, saying, “What is this thing?”

“I ‘unno” was all Apple Bloom could say. As far as Sweetie could tell, it was some sort of stretchy tube that—with a sucking vacuum, it latched onto her nose!

“Mmmmph!” Sweetie shouted, shocked to realize it had already slipped past her nose, and all the way over her mouth. She couldn’t scream because it was muffling her voice and covering her entire mouth and nose and—! It was sliding up her face, like it was pulling her in!

“Sweetie Belle!” Apple Bloom shouted, immediately leaping to help her, and that was the last thing Sweetie’s frightened eyes saw, before it sucked her face, and then her whole head in. It was so strong, it effortlessly flattened her ears and crushed her hair against her head, and her horn didn’t even seem to slow it. Sweetie’s entire head was surrounded in stretchy sliding blackness that was strangely warm, squeezing around her neck and shoulders.

“Help me!” she screamed desperately, her cries muffled inside the squirming dark tube. She desperately tried to lurch back, but she just dragged the thing with her, like some weird living sock wrapped around her head. It was eating her! She felt Apple Bloom’s teeth lifting up the edge of the thing, trying to pull it back over her shoulders, but it wouldn’t stop! It slid forward, and when it hit her shoulders, Sweetie couldn’t even stand anymore.

A crushing force forced her forelegs straight against her body, as it engulfed her shoulders, sliding down her hyperventilating chest. Sweetie Belle crashed to the floor absolutely miserable, after Apple Bloom couldn’t hold Sweetie’s entire weight up by her grip on the tube. Sweetie just had to lie there, while the thing crawled relentlessly down her torso.

She tried to shout for help again, but her mouth felt so strangely numb. She just felt... soft, like it was squishing her like clay. She got her mouth to open, but that was it. She just had to stay there mouth limp. Her scream died in her throat, as she struggled to breathe. It was just so much effort to drag air into her lungs again. She couldn’t even feel anything above the tips of her forehooves anymore, sticking limply out of the stretched tube. Her hair was... like, sticking to her or something. What was going on?! It was eating her! She didn’t want to get eaten she wanted to live!

She wiggled her hindquarters trying to squirm away somehow, but even that was weirdly hard to do. Not that Sweetie couldn’t feel everything that hadn’t been engulfed, but it was the only thing she could feel. She could feel her butt and her torso, and her hooves and... that was it. Why was it so... hard to think all of a sudden? She felt so empty from the lower waist forward, and so solid in her hind legs.

Sweetie Belle heard Apple Bloom shout “Noooo!” for some reason, and Apple Bloom’s voice just faded out as she heard it. Sweetie couldn’t even twitch her ears anymore. It was eating her ears! Or, they were plastered against her and... like... caving in? Sweetie felt numb and helpless, and her bottom just struggled there, with her tail lashing, and her hooves kicking weaker and weaker.

Sweetie Belle realized she couldn’t breathe at all anymore. Her mouth was open but... it was open, wasn’t it? She couldn’t remember. How do you move your chest to breathe, again? Dimly, she was aware of the tube engulfing her forehooves entirely, figuring only a matter of time before it ate all of her. She stopped being able to feel terrified though, and just felt strangely comforted, warm and wrapped in tingling blackness. What was she worried about again? Something about a tube. She could still feel her bottom half. She thought about moving her hooves, but then she... didn’t think about moving them? They just stilled and lay limply.

Sweetie Belle could think about her bottom, but she just couldn’t summon up the urge to move it, besides maybe peeing. It was weird how strongly she felt the little tension in her bladder, just because of how numb her entire front half felt. She felt the food in her lower intestines, the tiniest little gurgle. She swished her tail in confusion, but then she didn’t even have a reason to swish it. She could, but... she just lay there peacefully. Her tail flopped down right against her little cunny, and even that felt especially prominent in her current situation. Sweetie was always so sensitive down there. It was really hard to be a good little filly sometimes, when she wanted to be with the boys and feel what it was like to have the colt’s thing inside her. So, that’s all Sweetie thought about is her tickly cunny, and her limp hind legs, the muscles in her tail, her slow digestion, and a vague need to urinate. She just lay there, just... having those things. Not knowing what to do.

But then Sweetie Belle started feeling somepony... talking to her. Not talking to her, but telling her things? She started to get scared again, because this pony was scared, and telling her to be scared and confused. It sounded/felt like... Apple Bloom? Sweetie Belle couldn’t see or hear her or anything, but Apple Bloom could somehow tell her stuff.

Like how Apple Bloom told her to squeeze that lower part of her intestines, that Sweetie Belle could still feel, and Sweetie started to feel strange because she didn’t recall eating apples lately. She didn’t recall much of anything, really, but her... inside food was changing, that much was obvious. There were a lot of things changing, flowing into her. It was like the other pony was flowing in her veins. Her butt’s veins at least.

Apple Bloom seemed to want to stand up, so Sweetie moved her hind legs, and it was just like there were forelegs bracing her, because she could stand them up easily even though she couldn’t feel her own forelegs. So Sweetie just half stood there on just hind legs, feeling more and more... connected with Apple Bloom. Apple Bloom was so confused, she couldn’t even be terrified anymore. Sweetie didn’t know why her friend felt that way, or why Sweetie could feel her, but one thing she did know is that Sweetie Belle kind of did need to go to the bathroom now, especially after an experience like that!

Apple Bloom wanted Sweetie to lift her tail, so she did, raising it in a high arc that she couldn’t see, but could feel from the tension in her butt. It seemed like a reasonable enough request, and with her rear dominating her perception, Sweetie was feeling particularly amenable to such requests. She moved her hind legs around like Apple Bloom wanted her to, and even though she couldn’t see, Sweetie felt oddly like she was being watched down there. That sort of embarassed Sweetie, but she couldn’t blush in her head. All she had left was the urge to squirm her bottom parts. She wasn’t supposed to do that when ponies were watching, but she forgot why, so she kind of did anyway. Then a hoof came and started spreading apart her cunny!

Sweetie didn’t know what to think. She shouldn’t let ponies touch her there, and it felt very exciting and forbidden, but she couldn’t remember why or how. She just sort of... responded to that hoof touching her. The contact on her butt and the stretching of her vulva seemed to correspond with Apple Bloom feeling a guilty curiosity, and stretching her forehoof back somewhere. Oh, it must be Apple Bloom touching Sweetie Belle! Sweetie was okay with that. They were connected, right?

It didn’t last very long though. Apple Bloom inspected Sweetie’s cunny with a hoof, and wanted Sweetie to twitch her butt place, so she did. Then Apple Bloom turned forward, and Sweetie stood at attention, waiting eagerly for Apple Bloom to start walking. When it happened, Sweetie moved her two hooves around, just like Apple Bloom felt like she should. Sweetie’s lower body turned this way and that, lifting her tail, swinging her tail around. Apple Bloom started telling Sweetie about a resurging, fearful excitement, making Sweetie want to run somewhere and get help. Yes, she wanted to run! She didn’t though, because she was just standing there waiting for Apple Bloom to run. Thankfully Apple Bloom didn’t make her hold out long, telling Sweetie to push her hind legs forward strongly, while Apple Bloom took care of the rest.

Sweetie could... sort of feel what Apple Bloom felt. She distantly felt Apple Bloom’s forelegs pounding on the boards in the floor of this abandoned adult products store they’d been exploring, just as Sweetie felt her own hind legs beating the ground in a familiar, well practiced gallopping motion. She had never really thought about how legs moved when running, but now that’s all she could think about. Matching her hind legs to the motions of those forelegs ahead of her somewhere, running with fear, but also with purpose. Purpose for what? Sweetie didn’t care, as long as she got to run like this! This was kind of fun!

The worry from Apple Bloom fought with the calm and curiosity from Sweetie Belle. It wasn’t so much curiosity, as something more basic than that. Wanting-to-touchyness. Sweetie certainly felt very basic. She could only feel her cunny and her tail, and her legs as Apple Bloom told her when to push them sideways into a turn, or when to slow down and speed up. Even walking was interesting, and strangely intimate because Sweetie felt like she was part of Apple Bloom’s walking now. She felt like she was part of Apple Bloom, in a way.

When Apple Bloom stopped running, Sweetie felt her telling many contradictory things. Fear, and then outrage, and then desperation, and then confusion, and back to outrage, and then hope, then embarassment, and a forbidden desire. There were vibrations in the floor up Sweetie’s legs, that Sweetie had to guess was somepony walking around her. Sweetie walked her hind legs where Apple Bloom told her, turning somewhere Apple Bloom wanted to face, her friend looking up and talking... was that Apple Bloom’s mouth moving? Sweetie couldn’t be sure, as it was very far away from her, but it did correspond to a slight vibration in her hindquarters. And Sweetie could feel it when Apple Bloom’s forehoof stomped the floor, radiating up through Sweetie’s own hind-hooves.

Something grabbed her tail, and Sweetie was shocked because Apple Bloom was shocked, and then a force that felt like a unicorn’s magic was pushing her hindquarters around. Sweetie felt from Apple Bloom that she was being watched again, but tried not to wanty-touchy, or wink this time, because Apple Bloom was also scared of offending somepony. So Sweetie just endured it for her friend.

It went on like this for a while, this storm of feelings and tellings from Apple Bloom, along with what felt like attention from a unicorn. Then Apple Bloom just felt inconsolable, and Sweetie sank her own rump down onto the floor, sympathizing with poor Apple Bloom’s distress over whatever it was. There, Sweetie felt her bushy tail, her puckered asshole, and her soft vulva pressing against wooden floorboards, along with her heels. This distressed Apple Bloom more, for some reason, and Sweetie hastily climbed back to her hooves, wanting to feel her bottom less so that Apple Bloom didn’t feel embarassed about it. But then Apple Bloom felt strangely guilty, guilty for being embarassed! Sweetie wasn’t sure what to do, but she eased up her digestion, gurgling pleasantly to encourage Apple Bloom’s sense of calm.

They walked around some more, and up some stairs. Sweetie had to move her hooves different for that, as she tilted her torso upward to... let Apple Bloom be higher on the stairs than her. That was when Sweetie realized, or at least, understood that Apple Bloom was right there in front of her, where that connectedness feeling was coming from. So Sweetie walked her hind legs along behind Apple Bloom, stepping up the stairs until they reached a flat area again, and turned a corner.

Then Apple Bloom stopped, and there were some feelings of hesitance, and acquiescence. Then she told Sweetie to plant her hooves, and raise her tail, just like they weren’t supposed to. Sweetie did, feeling a little naughty for doing so. That was nothing compared to the naughtiness she felt after that, though! Somepony started licking her cunny!

Pushing against her smooshy pliable petals, that tongue stroked every inch of her. Sweetie had never been inside herself before, and so the tongue tried to do it, snaking into Sweetie’s special place, that she was usually too shy to touch. It felt strangely good to be spread open that way, though she felt very tight right where she opened up. But the tongue pushed past that, and made Sweetie feel herself deeper than she ever had before. That tongue was really in there! All wriggling around inside her so pleasantly.

Apple Bloom was so scared at first, but once Sweetie started getting delved in with that tongue, even Apple Bloom was swept up in it. Apple Bloom was feeling really good about this, and telling Sweetie to stiffen her legs, and flick her tail, and keep presenting no matter what. The more tingly and incensed Sweetie Belle got, the more aroused and eager Apple Bloom got, a desire coming from her to experience something forbidden, that she’d never been able to justify before today.

Sweetie didn’t know who it was. She couldn’t see, and couldn’t find her head or anything, because of some reason she couldn’t recall. So it was really scary when she felt her vulva spread apart by a warm tongue, making her all tingly and wanting to put a colt inside her. It was less scary because Apple Bloom seemed to be telling her to reluctantly accept what was happening. Sweetie wasn’t sure if she wanted to though. She quivered down there, and her bladder gave an alarming clench.

That changed Apple Bloom’s acceptance, fast! Apple Bloom told Sweetie to jump away, so she did. Then there was more embarassment and frustration, and Apple Bloom told Sweetie to start walking this way. Going back down the stairs was neat, because instead of tilting her torso up, Sweetie had to tilt it down. Really Sweetie Belle was glad for any sort of feeling of herself at this point, even if it was just part of her cute little white belly. They walked along after reaching the bottom of the stairs, boards beneath Sweetie’s hooves changing to ceramic tiles. Then Apple Bloom steered them around, and told Sweetie to lift her tail again. Then Apple Bloom told Sweetie Belle to squeeze her bladder.

It wasn’t telling in words, or even feelings! It was like Apple Bloom was in there, trying to squeeze down on Sweetie’s bladder. Sweetie hestitated, but Apple Bloom told her again, with a feeling of frustrated fright. Sweetie didn’t know why Sweetie was being so silly about this. This was an emergency, no time to be embarassed about peeing in front of your friend! So Sweetie squeezed her bladder obediently, and felt the pee start to rush out from her vulva.

Sweetie felt really relieved at this, and that kind of conflicted with how Apple Bloom felt kind of ashamed of this. But eventually Apple Bloom reluctantly conceded to the relief, and didn’t feel ashamed of what she was doing to Sweetie. That was a strange feeling, since it was Sweetie herself who was doing the peeing, so she should be the embarassed one. Sweetie didn’t really question it though, just felt a little hesitant to really indulge squeezing down on her bladder or not.

Once Apple Bloom told Sweetie they were done, Sweetie was surprised, but then sort of unsurprised at a hoof wrapped in tissue stroking along her vulva. It would make sense if Apple Bloom had to wipe her off, since Sweetie Belle couldn’t find her forehooves. So she just relaxed while Apple Bloom took care of her. Then they both felt more calm as Sweetie walked her hind legs behind Apple Bloom, striding forward despite the slight, brief vibration that went through the floor behind them. They retraced their path, Apple Bloom telling Sweetie to walk more and more reluctantly, but also to quiver with anticipation. Sweetie wanted more licks, even though she shouldn’t, and that’s what she started thinking about thanks to Apple Bloom’s semi-conscious prompting.

Sweetie Belle got those licks, and more, once they were back up the stairs where they had been before. They stopped, and there was a sense of recognition, and agreement. Then Apple Bloom went up one really big stair, and Sweetie had to stretch her legs one after the other as Apple Bloom pulled her up onto something plush and soft. Then she wanted Sweetie to crouch down, and push off with one hoof. By both of them pushing with one hoof on the same side, they easily rolled so that Sweetie was lying on a soft surface, belly up. Sweetie had a good idea of what to do now, and spread her hind legs sensuously, when Apple Bloom wanted her to be teasing for the pony who was watching her. Sweetie’s soft tail cascaded down off the edge of the thing under her, and left her cunny nicely exposed. Sweetie just wished she could see, but she kind of felt the anticipation Apple Bloom felt, the moment a tongue touched down on her soft petals.

Sweetie Belle couldn’t believe how good that tongue felt. It just seemed to feel better every time it happened to her. Her tail was flopping beneath her, and tingles were rushing through her bottom like liquid lightning. Not just her bottom either, the tingles rushed on through her, and then kept going right into Apple Bloom! Apple Bloom was feeling so good, like Sweetie was sending the feelings to her. Sweetie could vaguely get the feeling from Apple Bloom that her head was hunched forward, and her breathing hard. Sweetie wasn’t breathing though. She didn’t even know how to breathe. She knew how to quiver though, and to close her hind legs around the pony licking her, and to wink her horny cunny against that tongue.

It was so amazing, she just felt better and better, like the pleasure was rolling in her bottom. Sweetie wanted it more and more. She jerked in surprise as something started rippling inside her, a powerful regular contraction. She wanted more though! The tongue didn’t even need to touch her anymore. Though every stroke of it was like pure pleasure, this rippling inside thing was enough to make pleasure flow through Sweetie Belle like a dam breaking, so much that the hind legs she did have twitched spasmodically up in the air. Sweetie didn’t know what it was, but she loved it so much! Almost as much as Apple Bloom.

The ripply feeling stopped though, and when Sweetie Belle faded from the haze of pleasure, she felt Apple Bloom start feeling hesitant, unsure, then alarmed. She needed Sweetie to hurl her off the bed so she could run somewhere, so Sweetie helped with that nervously. But then there was a calming presence, calming Apple Bloom down. Sweetie didn’t know what, but Apple Bloom’s panic, making her roll off the bed and dance her legs with Apple Bloom’s around on the floor, was patiently calmed and soothed.

What Sweetie felt now from Apple Bloom was resignation, but also an excited anticipation. Apple Bloom’s threshold of resistence had been crossed long ago, and she was more than eager to do something with Sweetie Belle. That’s all Sweetie could tell. Apple Bloom told Sweetie to present herself, raise her tail, and brace her hooves even harder on the ground. Sweetie did so with relish, anticipating more licks. Apple Bloom also wanted Sweetie to open her cunny... somehow. Sweetie didn’t know how to open her cunny without a hoof though. So she could only return confusion at that, but felt reassurance on Apple Bloom’s side. It would be fine.

Sweetie quivered with anticipation. She hoped she would get touched more. She liked being touched on her bottom. Her hopes were answered, well sorta, when a stiff thick object touched Sweetie back there. Apple Bloom told Sweetie to shy away, but when Sweetie did, Apple Bloom changed her mind, and wanted Sweetie to stay there resolutely. So the thick thing pushed into her, and spread her cunny’s petals wide. It was painfully tight at the surface, and this thing just seemed to get thicker and thicker. Sweetie couldn’t really feel the part going into her, since the pain of stretching was so distracting. But that didn’t compare to the little hot explosions of pain, as something started poking her, right where she was tightest! She tried to put her tail down, but Apple Bloom insisted on her keeping it up, even though Apple Bloom was also quivering from the painful pokes and pricks.

They stopped quickly, and the conical thing pulled out of her. Then there was a wonderfully warm wet cloth pressing against her bottom. Sweetie relaxed into that, even without Apple Bloom telling her to, because she really felt like she needed a break after that painful whatever it was. After a while, the warm cloth began gently rubbing Sweetie’s vulva, and whatever pain they’d had earlier was thoroughly soothed. She felt really good actually, each stroke making her tingle more.

Then the cloth left her rear end, and the tongue was back. Sweetie quivered her bottom exquisitely, feeling all tingly from that tongue. She lifted her tail right up, and spread her legs squarely, just like Apple Bloom told her to, just like that tongue rewarded her for doing. Sweetie was gonna be the very best stander and tail lifter in the world if it felt like this!

A weight came down on top of Sweetie Belle’s hindquarters. Sweetie really liked that feeling. This must be what it felt like to get mounted by another pony. That must be exactly what was happening to her. Sweetie wanted to see the other pony, but couldn’t turn her head or... anything, just slightly tilt her torso, so she just appreciated where she was. And Sweetie knew what being mounted meant. It meant a boy thing in your cunny! Sweetie always had wanted to know how that felt. Somehow this...thing she guessed, was helping Apple Bloom help Sweetie Belle feel it. Sweetie couldn’t remember why a boy thing in your cunny was bad, just that she really wanted to feel what it was like. She hoped it would be like that tingly twitching thing, that the tongue made her do.

This mystery pony didn’t disappoint, and it wasn’t long before something thick and flat was prodding Sweetie Belle in the butt. Apple Bloom was biting her lip, Sweetie could tell that much, but Sweetie had no lip to bite. She just focused on her cunny, trying to shift her hips to make it easier to be bred. That broad shaft pressed her vulva wide, and sure enough, Sweetie began to feel it sink into her depths.

It was just like Rarity’s romance novels, the ones Sweetie wasn’t supposed to read. She didn’t... wait, what were romance novels? Anyway, she now knew what they were describing, and it was really accurate too. Sweetie Belle’s beautiful flower was spread, and the shaft thrusting in her was so deep and hot. She felt it pushing against her in there, and really understood why mares in those books cared so much about the thickness. It was just thick enough to stretch her so wide she tingled, but not too thick to provoke that weird tension she felt earlier. The hymen, that’s what it was! Sweetie’s virtue. Why had she forgotten about that? Wasn’t that supposed to not be... broken or something?

Oh who cares, Sweetie was too busy enjoying this indulgent thrusting. It felt soooo good when it slid along her in there. She felt Apple Bloom getting more and more excited, both paying more attention and less attention to Sweetie Belle. Apple Bloom was seeing Sweetie Belle as less of a person, and more of a beautifully stretchy cunny. And Sweetie loved feeling like that, as odd as that may sound. The tingles rose and rose in her, and to Sweetie’s excitement, she was sure she was going to feel like she did before, with the tongue! That incredible jerky twitching feeling, except now she had a penis opening her bottom wide. The feelings rushed over her bottom in waves, and rolled through her in electrifying pleasure, making Apple Bloom cry out as it got bigger and bigger. Sweetie gleefully shared that pleasure with Apple Bloom, delighting in being swept up in it, and also in making her friend be taken by it more and more.

Then the ripples began again. Sweetie felt so incredible. It was like her whole body was doing it. Sweetie could now feel that the thing that happened inside her, that suffused her and Apple Bloom with so much pleasure, was a very purposeful action: a repeated clamping down on the penis inside her. With her cunny so filled, Sweetie could feel every moment of what happened to her in fine detail. She had to bob her tail in the air, and cross her hind leg delightedly, squeezing around that shaft forcing her open and deep.

Once the clenches stopped, Sweetie distantly felt a sense of triumph from Apple Bloom. Sweetie tried to waddle her hind legs forward to ...find Apple Bloom? But she had to stand there, because that stallion’s forelegs had gripped her and held Sweetie’s hips in place. Sweetie couldn’t move at all then, because the penis started thrusting into her. Just like the mares in those romance novels, Sweetie felt so moved by the movement within her that she just wanted to stand there and take it, like a passive little maiden, filled with her ladylike need to be fulfilled.

Sweetie just hoped that the part at the end was anywhere close to reality.

Apple Bloom grew more and more distant, and it wasn’t long before Sweetie felt a strange slippery sliding alongside her body. She kept bracing her hindquarters and taking in that penis just like Apple Bloom said, but Sweetie Belle started to feel confused, and lost. She started to feel weird things on her sides, that separated from her body as this sort of... sheath thing slid further up her torso. She lost Apple Bloom entirely then, and Sweetie’s torso just fell forward, unbalanced without anything to hold her in front. The weird things on her sides moved sort of like her hind legs, as she squirmed about in desperate, pleasured confusion. And not once did the thrusting stop.

Sweetie had to push these weird things against the ground, to push herself upright again, because that made it easier for the stallion to fuck her. Sweetie would do anything to make that happen. She couldn’t just lay there anymore. She had to rock back against her prince, their beautiful unity bringing about the miracle of conception. Of... conception. Foals, that’s right!

Sweetie Belle realized those “things” were just her arms. She was just standing there like normal on all fours, if you could call it normal for a little filly to be experiencing a long, hard fucking. Her head was... she could feel her head again! It was hard to pay attention from the sliding sensations in her post-orgasmic cunny, but she could tell her head was here, and still wrapped in this tube thing. And a stallion was about to make Sweetie Belle pregnant, with a foal. With a wet sound, her mouth broke open, and Sweetie Belle gasped in a deep breath.

The thrusting paused. Sweetie stood there panting for breath now that she could. She thought she might have heard voices. Did she have ears again? Was this thing uneating her? It was too hard to make out anything legible. With no other ideas how to get this thing off her head, Sweetie just squirmed back into the stallion mounting her, rocking herself to slide on his penis. She was craving a foal something fierce, and her thoughts were slow still, struggling to make the connection between stallion, Sweetie Belle, and Sweetie Belle giving birth... and that being a bad thing.

He started thrusting in her again, and that made the sheath start crawling itself right off her head! That must be it. This big, grown-up mounting thing wasn’t to give her a foal. It was making the tube set her free! Sweetie moaned, her voice muffled inside the tube, and threw herself into it with abandon. “Alright, her horn is comin’ back!” Apple Bloom’s excited and relieved voice drifted to her. Sweetie wanted to ask, but on the other hand she really didn’t want to think that the thing had eaten her horn away to nothing. Plus she couldn’t be heard legibly through it from inside, she was pretty sure.

“I’m me again!” she shouted nonetheless, in case anypony would understand. It came out of her joyfully and thick with passion. She felt so incredibly tingly, and it was rushing up and down her whole body this time! The penis inside Sweetie Belle swelled up, making her moan right through the the tube. She had wondered what that was like, and again she was not disappointed. Like the sweetest inside kiss, Sweetie’s sources had said, and they were right. That turgid flesh was pressing on everything Sweetie had in there, making her hunch forward like... like Apple Bloom had been doing. Sweetie was well on her way to orgasm.

Her ears flopped out, and the tube started crawling down Sweetie Belle’s face, and she wanted to see so bad. She wanted it to slide past her eyes, and this incredible fucking was giving her just what she wanted. It slid past her eyes, while Sweetie panted into the tube, looking around wildly, then staring forward at her fascinated friend. Sweetie’s eyes went liquid as she saw Apple Bloom. They were in the ...library? Sweetie didn’t know how they got in the library, but she was just so glad to feel normal again. As normal as she could feel with the flat head of that penis jamming against her insides. For a minute there, Sweetie didn’t think she was ever going to see her friends again. And there she was! Sweetie wanted to thank Apple Bloom, for saving her.

Then Sweetie crossed her eyes and looked at the tube sliding off her muzzle. She still panted heavily into it, swaying in the thrusts that drove her to orgasm, but couldn’t say anything with it wrapped over her face. Then her lower jaw dropped out, and it was only attached to her nose. Then it dropped off Sweetie entirely, flopping harmlessly to the floor, and she was free. The spicy scent of sex, stallions and Sweetie Belle filled the air, as Sweetie was the one standing there now, getting fucked all by herself. “Thank—” Sweetie tried to say, catching her breath. “Thank you...” she managed, too lust addled to really communicate more with her friend.

Apple Bloom didn’t respond, but looked above Sweetie Belle, and shouted, “She’s loose!”

Oh of course, Apple Bloom was looking at the pony who was mounting her! Sweetie didn’t even know who it was! Sweetie turned over her shoulder and gasped in surprise. The... the librarian? But she was a mare! Sweetie bit her lip in confusion, then huffed hotly as she thought about the penis within her. Was it a dildo? Sweetie had heard about those. This one felt so real though! And if it was, then why would Twilight have such a lust addled, half lidded expression, as her hips jammed up against Sweetie Belle’s over and over again?

Sweetie turned forward, just feeling that and crooning softly in pure joy.

“Y-you cain let her go now miss Twilight,” Apple Bloom said uncertainly. Sweetie’s eyes snapped to look at Apple Bloom in alarm. She didn’t want to be let go! Not when it felt like this!

“N-ngh-gotta...gotta...” Twilight answered, in a mare’s voice, still not stopping her thrusting, to Sweetie Belle’s great delight.

“C’mon, y-you’re gonna make her pregnant!” Apple Bloom said frightfully, running around behind them, clearly just trying to pull the mare gone stallion off of Sweetie’s rump. Sweetie couldn’t watch her, because she was too busy getting swept up in orgasm. When that didn’t work, Apple Bloom gallopped up and started trying to pull Sweetie Belle out from under Twilight Sparkle.

“Apple Bloom, please,” Sweetie said struggling with the frantic filly. “The... the squeezy thing... can’t stop now! Let me do it! I need to!”

Apple Bloom paused, but still held onto Sweetie, who planted her hooves and breathed with determination. She closed her eyes and slowly tilted her head back as the tingles rose and rose in her. Her pitch rose and became more urgent. And then she couldn’t stop squeezing. That thick penis jammed into her, and Sweetie Belle couldn’t stop squeezing—!

Sweetie panted desperately the orgasm ripping through her. She struggled to get one hoof up onto Apple Bloom’s own shoulder, just as Apple Bloom held hers, looking fearfully but needily into Apple Bloom’s eyes. “T-t...than..k...” Sweetie managed to say, unable to even think from the rippling she had to do. Her hips jerked in place, and her tail flopped back and forth where it lay pushed aside by Twilight Sparkle’s hot pelvis. Then, just as her clenches stilled, the penis inside Sweetie Belle started jerking and throbbing, so deeply wrapped in her flesh. With a gasp, Sweetie felt something blast against her in there, then again and again.

“She’s doing it,” Sweetie whispered urgently to Apple Bloom, pushing off to stand by herself, and just stand there being ...squirted in. “I–I’m sorry Apple Bloom,” Sweetie said tearfully, wishing she could have been smart, and not gone all the way to getting a foal. But she loved how it felt so much! Those hot spurts bloomed in her inexperienced, but well used vagina. Sweetie knew what that meant in the books. She could almost feel it making the foal in her, right on the spot. She remained keenly aware of that thick slimy feeling Twilight squirted into her.

“Gosh darn it, miss Twilight!” Apple Bloom said angrily, looking up at the dazed librarian. “You got Sweetie Belle back, and mah butt, and now you’re gonna make her start foalin’? She couldn’t even say she didn’t want ‘em!”

Sweetie interrupted her tirade, saying, “It’s—okay, Apple Bloom. I w-wanted it. Because he I mean she I mean um... feels really good in there. I–I don’t care if I get foals in me.”

Twilight probably should have allayed their fears right then and there, but instead she got a devious look. Sweetie gasped and rocked forward as Twilight pulled out of her slick canal. Twisting around, Sweetie tried to inspect the damage. She ...didn’t really get many explicit descriptions from her sources, only emotions and consequences. Was she just gonna stay open like this until the foal was born? Was she... she was gonna have a foal now.

“I... I can’t believe it I’m...” Sweetie stuttered disorientedly.

“Oh golly Sweetie, she’s even drippin’ outta you. Ah’m so sorry, Sweetie,” Apple Bloom said sorrowfully. Sweetie did feel a dribble it—it was going down her leg! She lifted a hoof nervously.

“I–I can have a foal. It’s okay. I just... is my place okay?” Sweetie asked nervously. “I don’t know how it’s supposed to be. Is it supposed to come out?”

“Your place is beautiful, Sweetie,” Twilight told her. “What happened to you was natural, and it’s natural to want foals after that.” She turned to Apple Bloom and said, “Your friend keeps wanting foals because of that orgasm you felt. It must not have completely translated to you, but for her she’s got a lot of instincts that tell her it’s a good idea, whenever she feels that happen down there. You too, and any mare really. It’s just natural that the process that gives you foals, also makes you want them.”

“Wow, that’s... kind of scary,” Sweetie said in confusion. “I don’t ...think it made me want them. I’m just sort of... okay?”

Twilight smiled, saying, “The hormonal cocktail running through your body right now is going to make you pretty much okay with anything. It’s a very calming feeling. I can bet you’ll be freaking out over being pregnant just as much as Apple Bloom once it wears off.

“Or at least I could bet,” Twilight said impishly, “If Apple Bloom hadn’t missed one crucial detail in this equation.”

Twilight’s magic enveloped that evil tube thing, and floated it over to a box, that contained it with a soft click of the lid closing. “First, you get your hooves on a merge trap. That um... it’s not something I’ve experienced, but I imagine it was pretty terrifying at first.”

Sweetie’s ears went down at that. “Y-yeah it was...” she said softly. “I c-couldn’t talk or think or even breathe. I couldn’t feel my head or f-forehooves, and j-just had to stand there, and it was... okay. I didn’t want it to be okay though, but it was!”

“It’s supposed to be a way for lovers to get more in touch with each other,” Twilight said. “Well, lovers in a herd, that is, or swingers. It’s a very erm... adult thing, and not even many adults do that. But it’d be a lot less scary I assume, if you knew you were going to just fall asleep, and your butt would be used by Apple Bloom for a while.”

“Fall asleep?” Sweetie said uncertainly. “I just um... was. I could only feel my hindquarters and I... did things that Apple Bloom told me to.”

Twilight tilted her head at Sweetie curiously.

“Ah didn’t tell you anything, and how were you even gonna hear me?” Apple Bloom said in frustration. “Ah was just talkin’ to a butt by the time that thing was through with you!”

“You um... I just felt like you were telling I mean, wanting me to ...do things. Like when you told me to pee, or to stand there and get ready for a penis. U-uhm I was kind of weirded out at the idea of peeing in front of you though, sorry. I would have done it right away but I just...”

Apple Bloom gave the box a very wary look, saying, “Ah didn’t know that was... you. It just felt like mah own butt, except all fragile and soft like yours is. A-ah thought I just hadn’t figgured out your peein’ and that’s why it took a couple of tries before I got it. You mean you were this whole time...”

“I think I was a butt,” Sweetie said, blushing. “I could only do anything that my butt could do, so... I was still there, though. You really care about me, Apple Bloom. Thank you so much...”

“Ah guess I did feel you, Sweetie. When that thing ate mah legs, I started to feel ‘em coming back, but they were your legs of course. But it was real soothing, even just to walk around and stuff. Ah think you were... tryin’ to make me feel less scared?”

“I was,” Sweetie admitted, “But I mean, it’s just what anypony would do. I wasn’t thinking about it or anything I just... care about you, so I had to be the best uhm... butt that I could be.”

“This is beyond fascinating,” Twilight said eagerly. “I wonder how you kept... I guess conscious wouldn’t be the word. How would you even retain memories of the experience? Perhaps this is a special version? Your resistence had an effect? Ooh, this is going to be so fun to experiment with!”

Sweetie curled her tail around her much more well understood hindquarters, saying, “I–I don’t want to do that again. And I... I don’t want a... I mean, I was okay with you going in me when I was just a butt, but now I k-keep thinking about it and I dunno what I’d do if I got pregnant...”

Twilight smiled again, saying, “Don’t worry Sweetie, I certainly won’t ask you to be the guinea pig in this. I really need to read up more on these. I’ll order some books on them and do some research, and if anypony ends up like that again, it’ll be calm, confident adults.”

Meanwhile in the future:

“Mmmmph!”

“Rainbow Dash I told you not to—! Ugh, I hope you like being your own rear end. Do you want me to fuck you out of that thing, or do you want Fluttershy? Just—calm down. Point at the pony you want to be your front half, and hurry before it gets past your eyes. Okay, okay, yes I can see you pointing. Just relax and let it happen. That’s right just lie down and don’t worry, we’ll be there for you soon. ...Fluttershy, get your tail over there. Dash is gonna need to be your butt for a while.

Meanwhile in the future future:

“Land sakes, Rainbow. Ah didn’t notice any difference. You’re still a horse’s ass!”

“Now, the second thing you missed, Apple Bloom, was not noticing the lack of a certain something between my legs,” Twilight said informatively. She lifted her tail for the earth pony, and Apple Bloom looked reluctantly at the limp, swinging phallus there.

“Anything supposed to be back there?” Twilight prompted, “Something very important to having foals? Maybe two things, perhaps?”

“Oh jumpin’ plum pie, you ain’t got any balls!” Apple Bloom realized. Sweetie butted up against her to look too.

“Wow,” Sweetie said critically, “So are you a mare or a stallion?”

“I’m a mare,” Twilight said, turning to face them with a satisfied expression. “This phallus is just a spell mares sometimes use to feel like stallions,” she said, “Or to make other mares feel like they have stallions. Like a mare named Sweetie Belle, perhaps?”

“But you still put a foal in my womb!” Sweetie protested. “I felt it. You were squirting like crazy in there!”

Apple Bloom looked at Sweetie worriedly.

“S-so it’s alright,” Sweetie stuttered, shifting on her hooves, “I mean s-so I mean, I felt it, so it doesn’t matter if you um...”

Twilight sighed. “Alright, you two. Let me tell you a story about this magical thing called the prostate gland...”

One story later, and both were nodding in understanding, “Ohhh.”

“Yes,” Twilight concluded, “So a stallion’s fertile seed can just be—in the case of this spell—just a bunch of white goo, that feels really good.”

“I don’t get why you did it though,” Sweetie said, lowering her ears. “You... you deflowered me!” the little unicorn filly exclaimed in dismay. “I was supposed to save my virtue for my one true love. Now what am I gonna do?”

“It was necessary, Sweetie,” Twilight told her with a sigh. “We tried just making you orgasm, but you had to be mounted and fucked before the merge trap would even start to let you go. Anyway, as for your virtue, do you know what your special somepony will think when he finds you didn’t save it?”

“He won’t ...like it?” Sweetie asked confusedly.

“He’ll think ‘My best friend in the whole world is enjoying me so much,’” Twilight said. “He’ll think ‘Gosh does this feel good.’ And you know what he’ll think, if you kept your virtue?”

“Um... no, what?” Sweetie repeated reluctantly.

“He’ll think ‘Am I a bad pony for hurting my best friend in the whole world?’” Twilight said. “He’ll think ‘Why can’t I fit inside her? Is there something wrong with me?’”

Sweetie blinked cluelessly, and Twilight stated it frankly for her, “A mare’s virtue is a pain in the patootie, and you want to get the thing properly removed, before you even think about lifting your tail for a pony you care about. What’s he gonna do, rip you open with his romantic penis?”

Twilight levitated a blue, cone shaped... thing, and a ...scalpel, and said, “So, you’re all set. This thing gets you all stretched out, and this gets any stubborn ligaments. So easy even a laypony could do it. And so much safer and more sterile than trying to do it with a freaking penis.”

“So I’m... ready for my special somepony?” Sweetie Belle said uncertainly, staring at the blue cone that was spotted with red speckles... her red speckles, she suspected

“Precisely!” Twilight said with a smile, carelessly bamfing the weird stuff somewhere else. “And anypony who has a problem with that, either they don’t understand just how much it can hurt, or they’re a big jerk, therefore they can’t be your true love. QED”

Apple Bloom turned her own rear, saying hopefully, “Cain you do it for me too, Twilight? Just uh... be careful because it really hurts when you make the little ligament things. Sorta like gettin’ poked with a uh, knife.”

Twilight facehooved. “Apple Bloom, you are really both a little young to be... getting into this stuff. I know you want to do more, but... maybe you should wait until you have a special somepony?” she suggested hopefully.

“Ah do, though!” Apple Bloom said happily, wrapping a hoof around Sweetie Belle’s shoulders. Sweetie Belle smiled and—wait, what?!
