Rarity felt a yawn stir in her chest, and raised a hoof to catch it gently as it emerged, lest she offend the Wonderbolt who was currently regaling the table with a tale of bravado and daring, as seemed to be the norm. She blinked drowsily and continued to listen politely to Misty Fly's story, even though the jargon and specifics of it were currently escaping her. Something about an Immelpone Turn and an out-of-control gondola, as far as she could tell.

It'd been a long day for her here at the Wonderbolt Headquarters: a day of measuring innumerable pegasi, interviewing them, observing them in flight, taking copious notes, and making sketches. On top of that, the cloudwalking spell wasn't quite the cantrip Twilight had made it out to be; she'd expended a great deal of energy into casting and maintaining it so that she could safely go out onto some of the more distant training fields and carry out research there.

It was hard work, not least because Wonderbolts tended to be so... well, like Rainbow Dash. None of them believed in sitting still when they could be zooming around at top speed. It was, she felt, a miracle that they were at least willing to sit down to eat supper.

But she was sure that, by the end of all this, she would have a wealth of knowledge that would help her to cover a glaring gap in the market - namely, the pegasus demographic. It seemed to be so firmly entrenched in Equestrian culture that pegasi "didn't do the clothes thing" that even pegasi themselves had come to believe it, even to see it as a point of pride. Certainly Rainbow Dash had never once seen fit to put on as much as a sock for the sake of fashion, if she could get away with not doing so.

That said, now that Rainbow Dash was a fully-fledged Wonderbolt, things had changed somewhat. Rarity was now struggling to remember the last time Dash hadn't been decked head to toe in her official blue-yellow flightsuit. But that wasn't the same. That was a uniform. Rarity wanted to show ordinary pegasi what they were missing; she wanted to break down that cultural wall and set them on the path to discovering their hidden beauty. But to do that, she first had to gain a much deeping understanding of the pegasus form.

"Y'know, you don't have to stay if you wanna get some sleep," muttered a raspy voice in her ear.

Rarity gave Dash a sidelong glance. "Oh, I'm fine," she whispered back. "It would be rude of me to leave now."

"No it wouldn't. This isn't the Royal Banquet. Just say you wanna go to bed."

"Misty's been so helpful to me today, though," Rarity said. "I wouldn't want her to feel like I didn't appreciate -"

"Seriously," said Spitfire from Rarity's other side. "You'll hear this story again tomorrow anyway. Trust me. She won't shut up about it."

"But I -"

"What's that, Miss Rarity? You're falling asleep in your chair?" Spitfire suddenly announced out loud, interrupting Misty in mid-sentence.

"I did not say that," Rarity said crossly. Another yawn welled up from her throat and she stifled it.

"Maybe Dash wants to carry you to bed, huh?" snorted an orange-maned pegasus from across the table.

"Shut it, Blaze," said Dash, scowling.

"I am sorry," said Rarity, "but indeed I am feeling rather tired all of a sudden. I hope you don't mind if I take my leave?"

"Want me to carr- I mean, take you back to the room?" Dash offered.

"I know where it is," said Rarity, a little more sharply than she had intended. Although she didn't dislike any of the Wonderbolts per se, she wasn't particularly fond of their boorish manner, even when she knew they didn't mean to cause any real upset. "Thank you for inviting me to your get-together, all of you. I look forward to seeing you in the morning."

"G'night," said Dash. "Yours is the bottom bunk," she reminded Rarity. "You might need to move a few things."

Rarity's eye twitched momentarily, but she quickly brought it under control. She'd seen that bed this morning; to say that "a few things" were currently resting on it was a laughable understatement. "Can't I take the top one?" she asked, raising her voice to a plainitive mew.

"No," said Dash. "I can't sleep on the bottom bunk."

"Why not?"

"I can't... I just..." Dash rolled her eyes. "I'll explain later," she said. "G'night."

"Good night," Rarity bid her, and departed from the Officer's Lounge for the sleeping quarters.

Why does Rainbow have a bunk bed anyway?, Rarity mused to herself as she trotted down the corridor toward their room. All the other Wonderbolt officers seemed to have their own quarters, but Rainbow Dash was currently quartered in what seemed like cadet lodgings. She vaguely recalled Soarin mentioning something about them being short on space... maybe that was it? She yawned again, deciding that she was too tired to figure it out now, and opened the door to Rainbow's room.

The unearthly pile of stuff was the first thing that so unwelcomingly greeted her. Rarity was fairly sure that the entirety of Rainbow's travelling luggage currently occupied the bottom bunk, and was even more willing to bet that the cupboards and storage units in the corner were completely empty.

Her hoof trembled. A less-cultured pony than her would, at this point, shove the junk pile onto the floor, turn out the light, and leave Rainbow to deal with it. Rarity was even sure that Rainbow was expecting her to do just that.

But she wasn't sure if she could bring herself to make such a mess, even if she was technically only displacing an existing mess. She could at least tidy some of this away. She sighed and resigned herself to it, hoping that Dash would come to bed shortly so that she could help. Oh yes, she would help. Rarity wasn't going to let that mare rest until she'd tidied this away.

I mean, for pony's sake. There are trophies in here, she noted, parting the pile with a hoof to see just what she was dealing with. Why would you leave these on your bed? You have a shelf for those! Rarity's horn lit up as she started to sort some of the items and put them away wherever she could find an appropriate place. After too-many minutes, she'd managed to whittle down the pile to half its former size. A crumpled-up, spare Wonderbolts flightsuit hovered in her telekinetic aura as she considered whether she'd done enough to warrant just leaving the rest for Rainbow and calling it a night.

Suddenly, she realised something was wrong. In her tiredness, she had missed something; something that normally wouldn't have escaped her notice. Rarity had a sixth sense for clothing calamities, and currently, she was in the presence of some anomalous apparel. Her head swivelled toward the flightsuit she was currently levitating.

That is no Wonderbolts uniform, she noted, unfurling it with an audible crinkling. The colors were close enough, but the material certainly wasn't. It wasn't even textile; this garment was made of shiny latex.

"A costume?" Rarity wondered aloud to herself. She pulled it flat and turned it over; she inflated it slightly with her magic to look within. Like the proper Wonderbolts uniform, it was one-piece, with a face hood connected to the neck. Definitely a costume; there was a hole for a unicorn's horn as well as wing-holes on the back.

That's most odd. Why does Rainbow have this? She could easily imagine Rainbow might have owned a Wonderbolts costume at one time; they were popular dress-up items for foals, and Rarity knew that Rainbow had had her obsession ever since she was a filly. But this outfit was definitely mare-sized. Rarity couldn't see Rainbow wearing this now. She'd never been that kind of wannabe; she'd never wanted to dress up as a Wonderbolt, she'd wanted to be one. And now she was. Even if she had played dress-up in her adulthood, why would she bring this thing here? It didn't make sense.

Could it be... a fetish outfit? Rarity immediately clapped her hooves to her mouth just for thinking such a suggestion. She and Rainbow had never really spoken about their private lives and sexual fantasies, but she was sure it couldn't be that either. That didn't fit the Rainbow she knew. Not to mention the fact that it didn't really look like a fetish piece. Rarity had seen fetishized uniforms before, and they were always trashy, skimpy things that only barely hinted at the style they were supposedly emulating. This "costume" was actually a fairly faithful recreation of the Wonderbolts uniform, save for it being completely made of colored rubber.

Her curiosity burned at her. She wanted to try it on, both to see if she could glean any more about it, and also because she hadn't yet had an opportunity to try on a Wonderbolts uniform of any kind while she'd been here. She had generously been given a spare one for her purposes, but obviously it wasn't designed with horns in mind, and she didn't have the time or resources to adjust it here. This outfit she had discovered provided a unique opportunity, and if Rainbow Dash didn't approve, well, she should have been polite and allowed her guest to take the top bunk, shouldn't she?

Rarity stretched, her tired muscles and bones clicking as she limbered herself. She climbed up onto the top bunk - she needed to lay down to get the costume on, and she certainly wasn't going to lie on that floor. Don't militaries frown upon such untidiness? she wondered to herself, as she laid on her back and began to ease her hindhooves into the neck of the costume. She supposed that maybe the Wonderbolts didn't fit the traditional definition of military; certainly they seemed much more self-directed than the Royal Guard.

The rubbery suit was supple and stretchy, and as much as Rarity hated to admit it, she was rather enjoying the sensation of putting it on. It clung to her legs and smoothed up the fur on her calves and thighs, squeezing tightly against her muscles. Although she didn't have Rainbow's lithe physique, she always kept herself in good shape; she knew that her own appearance had a subliminal but measurable influence on the decisions her customers made. She was glad for that now, as she knew that this outfit would show off every contour of her body, even more than the official uniform already did.

Latex barely ever factored into any of her designs, with good reason; it was cheap and vulgar, only really of any use for undignified applications such as fetishwear. For that reason she'd never really indulged herself in wearing it.

She shifted daintly side-to-side on her back, as if getting into bed, her horn aglow as she pulled the outfit taut around her legs and crotch. The definition of her thighs became highlighted with the rubber's sheen, her hindhooves now ringed with the electric motif that defined the uniform. Her ears were filled with scrunching as the hood crumpled between her mane and the bed, while she attempted to pull her forelegs in now. Already she could see the startling effect that the uniform gave; a blaze of cream that adorned her from neck to navel, ensuring that no eye could possibly miss her in flight. For a moment, she felt like she understood why Rainbow had desired this - the real uniform, that is, not this fake one - so badly. She'd always dismissed the Wonderbolts design as being deliberately gaudy and showy - which it was - but she'd never viewed it the way Rainbow had. As a symbol of belonging. A symbol of power and authority, power that had been earned, not bestowed.

Even if Dash came in now and complained at her, she felt that this little learning experience justified it. She understood Dash a little more now; maybe even understood the culture of the Wonderbolts better, too.

The latex pulled tight against her shoulders as her forehooves sank all the way into the closed sleeves. The suit let out a few unladylike raspberries of escaping air as she finally used her hooves to pull the hood on, carefully finding the horn-hole with the tip of her horn before pushing it through, feeling the ring of rubber stretch and cling at the base. A few more tugs and her ears popped into position, her mane squeezing out through the top and rear of the hood. Finally, she was able to push her muzzle out through the hole, the suit's eyeholes lining up naturally with her eyes. Her horn flickered a few times to make some minor adjustments, but otherwise, it was a good fit.

She gave a playful smile and admired her shiny hooves for a moment, before carefully descending the bunk ladder, again enjoying the sensation of tightened rubber against her body. She dropped to all fours and approached the plain mirror against the far wall to see how she looked.

Not bad, Rarity dear, she thought to herself. Well, that is to say, of course it was bad, in a strictly fashion sense, but she felt emboldened by how well she could pull off the Wonderbolt look, considering that it wasn't anything close to her typical fare. She turned to the side to admire her flanks, her cutie mark area now emblazoned by the Wonderbolts insignia, of course.

She turned around to examine her rear, but quite suddenly, she was hit by an unexpected and impossible sensation of pleasure. She gasped, a long, breathy exclamation of sudden shock.

What?

A buzz of arousal clutched within her nethers, and she let out another shrieking gasp. Her hindlegs clenched instinctively; she spun around, but to no avail. Something was happening to her, but nopony was doing it; she was alone and - a third, titillating squeeze inside her, tickling the deeper, guarded parts of her sex. Her legs buckled, her eyes wide in shock and sudden fear at these unknown sensations. She pressed a hoof to her crotch, dignity forgotten for the moment, and immediately regretted doing so, for the mere touch against her yawning sex made her want to moan at a volume that she was sure would penetrate these walls.

"Wh-what... what is going on?" she demanded of her reflection in the mirror, as she gingerly pulled herself to her wobbling hooves. The mirror had no answer for her, of course, but it presented her with an even more horrifying development.

"My mane!" she cried, as she saw that her coiffed curls were erupting into wild, bearish clumps of... wait... that wasn't hair... was it? It shone too artificially in the light to be natural hair. She reached a hoof up to try to do something about it, but found herself pressing into an unyielding, rubbery mass. Second-by-second, her beautiful mane was changing, growing, reshaping. It flared outward and upward, into a voluminous tuft that looked dreadfully familiar, for Rarity had been unable to escape this particular manestyle all day. She was now sporting the classic Wonderbolt look, and worse, it was firmly locked in unyielding latex.

"How is this haarrppnnn..." she began to wonder, but her mouth failed her at that point. Her teeth became stuck together, and her tongue refused to work, leaving her gaping and shooting air. She took a look back in the mirror and now, finally, realized that she was in serious trouble. The blue face hood seemed to be melded with her white coat, which was glistening in a very wrong manner, and where her lips should have been, she found only a hole, a deep circular gape. She was being transformed!

She didn't care at this point how she looked; she needed help, and fast. Her attempt to yell only resulted in a wheeze; she made a break for the door, but too late, it seemed. Another jolt of pleasure racked her spine and she crumpled again; her cry of ecstacy was utterly muted by her nonfunctioning vocals. She got back to her hooves, but the same insatiable pressure that had claimed her sex was now working itself deep within her anus, producing feelings of arousal that she'd only imagined before, but never truly felt. She wanted to cry, wanted to tear the suit off, but couldn't find any means to do so; it had melded with her utterly, to the point that it was essentially a second skin.

She tried to stand again, but this time her hooves literally gave out; they bent in a way that she knew was anatomically impossible, and she lurched and thudded to the floor.

This isn't... nngh... possible... she thought to herself, trying to block out the continuing sparks of pleasure that crackled within her motionless orifices. She tried to stand once more, carefully. She would crawl out if she had to. Her shoulders hunched awkwardly and she felt a tickling around the blades; tufts of white feathers were bulging from the costume's wing holes and spreading into beautiful pegasine wings... and then the third round of pleasure hit her, as these new appendages stiffened and twinged in ways that she had never even dreamed of. Her legs gave out completely this time, and she flomped back down on her belly, spreadeagled in her shiny uniform.

She didn't get up again. She couldn't. She couldn't move at all. She couldn't call for help, or even blink. She could only lay, gaping dumbly at the wall, and panic to herself.

For a long moment she wondered if she had been tricked; if this was some evil plot to eliminate her and her friends, one-by-one. But it didn't make sense. It was too elaborate. Too weird.

I am a sex doll, Rarity thought to herself, deciding that she may as well address the facts of the situation. She knew exactly what she had seen in the mirror; she knew what kind of face that was, what her mouth was doing, what that horrid ache in her sex implied. This... costume must be enchanted, and it's turned me into a rubber sex doll - no, this still doesn't make sense! Why would Rainbow Dash have such an evil thing?

There is a logical explanation for this. There has to be. The costume had transformed her into a pegasus - she assumed so, at least; she couldn't feel her horn any more. Right now, she imagined that she could easily be taken for a Wonderbolt, albeit a sex-doll version of one. So Rainbow Dash has a magic costume that turns ponies into Wonderbolt sex dolls... or maybe... maybe it's not hers? Perhaps I was wrong. Perhaps somepony else planted this for her, so that she'd find it and put it on... but then, why would Rainbow do such a thing... no... that doesn't make sense either...

She just didn't have enough information to go on, and her thoughts were just leading her in circles at this point. All she could say that was she was in an utterly unexpected predicament.

There's nothing for it, she decided. I must wait. Rainbow is coming back. She will find me, and then... then this will all be sorted out, one way or another.

She tried to ignore the growing heat in her sex as the minutes passed, the growing need she was feeling. That wasn't her. That surely wasn't her. She didn't need anything. She only looked like a blowjob-ready sex toy. She still had her dignity.

Her left foreleg was in view, and she noted something upon it: a line of printed letters, spelling out "Indigo Streak". Was that supposed to be a name? The knowledge didn't do her much good, either way.

The next hour continued to challenge Rarity's dignity. Her sex simply would not quieten, would not give her a moment's respite from the aching desire she was feeling. She wanted to clench her legs together again, but of course, she could do no such thing. It probably wouldn't have helped anyway. She tried to think of other things; sifting through the various fashion inspirations she'd had that day, but it was just impossible to concentrate.

Rainbow Dash! Where are you! Please! Help me!

By the time the door finally swung open and four hooves stepped into the room, her sex was practically burning with unreachable lust. Moments later, those same four hooves sprang up off the floor in shock.

"Wh... what... oh my gosh!" Dash shrieked, falling to Rarity's side. "Rarity! Rarity!"

Help me, please! Rarity thought, but she had no way to communicate it to Rainbow, even as the panicking pegasus lifted her neck and peered directly into her vacant eyes.

"Oh my gosh oh my gosh..." Rarity saw her begin to hyperventilate, but hurriedly bring her breathing back under control with a quick exercise. "Okay... okay... fuck! I can fix this, I can fix this... oh my gosh... just... don't panic, okay?" Her cerise eyes were full of fear, but Rarity could see she wasn't lying. She did have a plan. "Just wait there..."

This really wasn't how I imagined today would end, Rarity pondered, as Rainbow laid her back down. Please hurry, Rainbow... I... I don't think I can take much more of this...

Rainbow was gone for two minutes, and when the door swung open again, this time two sets of hooves entered. Rarity felt herself flush with a faint horror. She hadn't considered that Rainbow had gone to fetch somepony else! Who is that? Please don't let anypony else see me like this!

"Oh, Celestia," said a male voice. A stallion?! What are you thinking? Rarity wanted to scream. It was Soarin. It couldn't be anypony else. "I don't understand... how did she find it? Why did she put it on?"

"I don't know! I mean, I think I left it on the bed... oh my gosh, what are we gonna do?" Rainbow said, shifting from left to right hooves in panic. "There's a way to change her back, right?"

"No..."

What?!

"...I mean, well, there's one way, but..."

"Oh my gosh..."

I wish you'd stop saying that.

"I don't know... I don't know if I can do it, you know?" Soarin said.

Do what?

Rainbow began to pace in front of Rarity. "Can... can I do it?" she asked.

"I don't think so. I mean... somepony needs to... y'know, inside her..."

The hooves continued their agitated beat.

"You've gotta do it," said Rainbow, firmly.

"Well, like I said, I don't know if I can," said Soarin. "I mean, she's pretty and all, but she's not you. Plus, how am I going to explain it to her afterwards?"

"I'll explain it," said Rainbow. "I'll take full responsibility. C'mon, please, there's no other way!"

"You're sure she won't freak out about it afterwards?"

"She's probably already freaking out!"

I think I'm handling this rather well, actually, all things considered.

"If you don't fuck her, she's gonna go out of her mind," Rainbow added. "Trust me. You don't know what it feels like."

Wait.

"Well..." Soarin sighed. "I guess I can try..."

What?

Rainbow shifted over to the door. Rarity heard a key turn and a lock click shut.

What?! What do you mean?

"Y'know, I'd rather do this in my quarters," said Soarin. "No offense, but it's real cramped in here."

You can't be serious.

"Are you serious?" Dash growled. "What, shall we just carry a Rarity doll to your room and hope nopony sees us? Do it on the fucking bed!"

"You know, I am your superior," Soarin protested. "You're out of line, Dashie."

"You're being a superior dumbass right now! What are you gonna do, report this?" She took a deep breath. "Sorry, I'm sorry. I'm just... I didn't expect this... can you please, y'know... do your thing?"

Oh my gosh. They were actually talking about... using her. About actually... no. They couldn't be. They couldn't mean it. That was ridiculous. They had to mean something else...

A pair of hooves tucked under her and pulled her up into the air, swinging her over until she found herself back on the top bunk, her head lolling at the ceiling, legs spread wide and invitingly. She moaned silently as her stiffened wings bent against the mattress, her gaping sex joining the chorus with a desperate ache. Soarin settled at the foot of the mattress, tucking his wings away as he loomed over her.

"Dashie, I still don't think I can do this," he muttered.

"Yes you can! Look, she's just a doll, right? She's just a toy. Fuck her and throw her away. It's easy."

P-Please tell me that was figurative, Rainbow...

"I don't think I can do it with you here."

"What? How is this any different from fucking me yourself? I gave you permission!"

"It's... it just feels different," Soarin said. "She's not the pony you are."

Rainbow seemed lost for words for a moment. "Okay, okay, fine, I'll leave. But I'm locking the door behind me, okay? How long do you need?"

Soarin's cheeks flushed red. "...two hours?"

"Oh, get real. I'll give you twenty minutes, okay?"

"No, wait..."

"What?"

Soarin cleared his throat awkwardly. "Do you have any lube?"

Rarity heard the distinct clap of a hoof meeting a forehead. "Do you really need it?" Rainbow asked.

"Well, yeah," Soarin said, "I can't... you know... not raw, it's gonna chafe real bad."

"Well I don't have any," Rainbow muttered.

"It's okay. You can get some from my room."

"We don't have time for this!" Rainbow fumed.

"I really can't, Dashie," said Soarin. "Trust me, I need it or I can't do this."

To Rarity's relief, Rainbow seemed to realize that arguing the point would only waste more time, and she fled down the corridor, leaving Rarity alone with the last pony she ever thought she'd end up in bed with.

"I'm real sorry," said Soarin, the pegasus leaning over her and meeting her vapid gaze. "This shouldn't have happened. I don't know how this happened. I hope you're not too mad."

Well that remains to be seen, doesn't it? Wait... wait... what are you doing...

Soarin gently leant upon her, belly to belly, his hooves sliding delicately under her sides, where her lower ribs would have been, if she'd had a skeleton to speak of. She could feel his warm breath coat her face with a fine layer of condensed vapor.

What are you doi- oh my goodness! His bare hooves smooshed some part of her wings near the base - she thought it might be the tertial coverts, if she remembered her notes correctly... but milliseconds later, she didn't give a damn what they were called, she just wanted to croon with ecstacy at the way she was being touched right now.

"Dashie loves it when I do that," Soarin said helpfully. "At least, she told me she does."

Wh-why are you engaging in foreplay? Rarity silently exclaimed. Of course, there could be no answer, but there was, to her horror and delight, a reprise; the hooves delved again and this time she knew it was coming, and yet couldn't brace herself; her body tingled with electric joy as the stallion fondled her.

N-No... stop! she half-heartedly begged. Soarin's own wings had flared too; was this part of the pegasus mating ritual? She had no idea. It seemed to be putting him in some kind of mood; he was holding himself differently, his hindquarters were limbered, his muscles tensed. Despite his infamous predilection for fruit pastries, he was in superb shape.

His expression became one of concentration, suddenly, as he reached a hoof out of her sight; nonetheless, she could feel the undulations in the mattress, could read the telltale grimace in his lips; he was plainly hoofing off, trying to excite himself. Rarity almost felt disappointed that she wasn't able to entice him naturally. He wasn't her type, true, but she was accustomed to stallions fawning over her, and Soarin's tepid reaction made her feel somewhat snubbed, even in spite of the dire situation she was in.

The door swung open again, and Rainbow returned. For a few seconds, she said nothing.

"Did you get it?" Soarin asked. Moments later, Rarity felt a heavy item smack her on the chest, before it was picked up by Soarin's hoof.

"I'm gonna... I'll come back in twenty minutes, 'kay?" said Rainbow.

"Yeah," said Soarin.

For a moment Rarity feared that Rainbow would drag this out longer, but the door closed again, leaving them alone once more.

"Okay, let's do this," said Soarin. It wasn't until he leant back and began unscrewing the tube of lubricant with his teeth, that Rarity really realized this was actually going to happen. She was really, actually, going to... going to receive his stallionhood, and she couldn't do a thing to stop it.

This cannot be happenin-... oooooh! Something cold, wet, and slimy trickled deep into her most private area, utterly unimpeded, completely uninvited, and far from quelling her heat, only served to titillate her more. No... s-stop... stop... oh! P-Please! A long, thin instrument - a swab, she surmised, began to dab at her precious vaginal walls until she simply couldn't take it. This was horrible, beautiful torture, being prepped for something her sex so desperately wanted and her mind most desperately wanted to resist. She just wanted it to be over, already.

Soarin's hoof slid under her barrel, and she swiftly inverted; her face planted indelicately into the bedsheet, her rubbery tail bobbing as she settled. Those same strong hooves lifted her now, almost to a standing position, although the best her immobile body could settle in was an ungainly crouch, as Soarin mounted her.

The tantalizing stimulation she'd felt to this point could do nothing to prepare her for what followed. She felt it between her legs first, a brush of hot flesh against her cool rubber thighs; it was a mistake though, it was impossibly firm, it surely couldn't be -

That impossibly firm shaft entered her, and she lost it. She was surely groaning loudly enough to wake everypony who was currently asleep; she was surely shuddering with enough force to rattle the bed slats, but in reality, she hadn't so much as twitched an ear, and still that member buried itself in her, deeper than anything had any right to go. Oh f-f-fuck! Oh Celestia! she moaned to herself, almost out of her mind with lust. She no longer cared that this was an awful, unsolicited violation - she just had to have it, she had to take that cock, she wanted that cock more than anything else. In that moment, she would have sold all her clothes, both her boutiques, and joined the Wonderbolts as an uncouth ruffian named Indigo Streak, if only to be impaled upon that glorious shaft for a few seconds longer. She could see now what Rainbow saw in Soarin... no, what a terrible thing to think! Rainbow surely liked Soarin for other reasons...

The shaft pumped her again, and her impropriety was forgotten. Oh Celestia, please, harder, fuck me harder! Fuck me so hard, please! Even though her pleas were silent, she couldn't help herself begging for more. Soarin was definitely capable of providing the goods; that slickened cock was so hard, so sturdy, she felt like she was barely an obstacle to it as he humped her with practised ease. The distant echo of a climax arose in her, and she felt a faint terror; she could feel it was coming, she knew Soarin was going to take her to it... and she was already well past the point where she would ordinarily have reached her peak. She didn't know how she could possibly be driven any further, and yet it kept happening, taking her deeper and deeper into unknown fathoms of pleasure.

Words failed her, not that she was getting much use from them anyway. Soarin's relentless drive had pushed her beyond talk, beyond caring. She had to cum, she just had to, whether it was possible or not, she had to or she'd lose her mind... and indeed, as she finally broke into orgasm, her mind in that moment failed her, any hint of a thought extinguished in a roar of utter bliss. She may as well have been a rubber toy at that moment, for all the good she was to the world. And it didn't stop, for Soarin was in no way done; he was still very much a flesh-and-blood stallion who couldn't care for the non-thoughts of a doll, and he kept her in that mindless heaven as he continued his effort.

It was Soarin's own climax that brought things definitely to an end; he hilted in her, and those rapid jets of hot pegasus seed, contained in her tight inside, hit her with a power her mind couldn't quantify. She simply had no more ability to register it, no more pleasure that she could possibly take. She felt like her very body was disintegrating; her rubber skin losing all tension, parting from her. The tiredness she had felt before all this came upon her in a singular wave, and she passed out into blackness.

Her eyelids felt glued together. Her entire body ached, from head to hoof. Stretching her limbs brought discomfort and relief in equal measure. She sucked in a lungful of air and forced her eyes open, blinking out some heavy sleep residue.

I can move. I can move!

She brought a hoof to her mouth. Lips! The wings were gone. She had her horn. And that damned... costume was nowhere in sight. She saw only her white coat, albeit heavily mussed.

Her mane was frightful, she could feel so, even without seeing it. But it was over. The ordeal was over. Somehow, she was free.

She let out the faintest squeak as she sat up. Her sex was normal again, but the memory of all that had happened seemed to still linger within, and she felt fragile and tender. She leaned over the edge of the bunk, and found herself peering down upon a rainbow mane.

"Rainbow," she croaked.

Rainbow started and jumped to her hooves, turning to face her. Rarity noticed that for once, she wasn't wearing anything. Her eyes were tired and bloodshot; she looked pretty awful.

"M-Morning," Rainbow greeted nervously.

"Is it?"

"Y-Yeah, it's... nearly sunrise."

"Haven't you slept?" Rarity asked.

"No," said Dash. "Well, you kinda... took my bed," she said, grinning weakly.

Rarity took a few deep breaths. Her cheeks flushed pink as she tried to collect herself. Humilation was lingering at the edge of her feelings, threatening to swamp her, but she kept it at bay for now. "I... I want an explanation," she said, trying to keep her voice even.

Dash shuffled awkwardly. "Rarity, I'm really, really sorry."

"I just want you to explain," Rarity said. "I must know."

Dash shrugged. "It's... there's not really much to it..." She rubbed her mane in agitation. "I don't know where to start."

"Please," Rarity whispered.

Dash puffed out a tense breath. "Okay, well... that outfit you put on... it's not an ordinary outfit. It's enchanted. I mean, you know that already." She began to pace, her eyes unable to meet Rarity's gaze. "Soarin and I, we... well... we're sort of seeing each other. But not really. We can't. We're not allowed. It's against regulations. We're not allowed to have any kind of relationship. Soooo... one day Soarin showed me that outfit, and told me what it does. I was kinda weirded out at first, but I gave it a try."

"You gave it a try? Deliberately?"

"Of course deliberately," said Dash. "See, Soarin and I aren't allowed to have sex. We'd be kicked out if we did. But there's nothing to say he can't sleep with a doll. That's why he got the outfit for me. I put it on, I turn into a doll, we have sex, I change back... no rules broken, everypony wins. Plus, it feels fucking amazing."

Rarity blanched. "Language, darling!"

"Oh," Rainbow's cheeks flushed, and her momentary enthusiasm flickered away. "Sorry. Anyway, that's all there is to it really. It's not meant for anyone but me. I... I never thought anything like this would happen... why did you wear it?"

"To see how it looked," said Rarity, glaring. "I cannot believe that you would be so unimaginably stupid as to leave such a dangerous item lying around on your bed."

"It's not meant to be dangerous," Rainbow mumbled. "I'm so sorry, Rares. I... I don't know what I can do to make up for this. I... I had to get Soarin, he's the only one who could have changed you back... I'm so sorry about what happened..."

She wiped a tear from her eye. "I messed up bad. Whatever you want to say to me, I deserve it."

Rarity sighed. "Darling, I honestly don't know what to say. I... I need time to think. I shan't be staying here any longer."

"Yeah," said Dash sadly. "Tell me whatever you need, I'll sort it for you."

"You should go to bed," said Rarity, clambering down from the top bunk. "Get some sleep."

"I can't," said Dash, eyeing her mattress mournfully. "Training sessions all day. I'll... I'll walk you to the station, okay?"

"Very well," said Rarity, trotting for the mirror. Her suitcase magically opened and a brush floated out, pursued by several combs, which began to attack her bedraggled mane and force it into some semblance of order. When done, she assembled her notes and packed her bags.

Rainbow didn't say a word for the entire walk to the station, communicating only in nods as she hauled Rarity's luggage. Despite Rarity's low mood, it just didn't sit well with her. If things were to be put right, she supposed she would have to take the first step.

"Rainbow. Rainbow Dash," Rarity said. "Rainbow Dash, you will look me in the eye, right now."

Rainbow lifted her head, flinching as she met Rarity's hard stare.

"I cannot say I'm not angry with you. To put it bluntly, I'm furious. But..." Rarity sighed. "I don't want this goodbye to be painful. You don't deserve that."

Rainbow's eyes watered. "Dammit... y-you're tryin' to make me cry, aren't you?" She wiped her nose on her foreleg. "H-Hate it when you do that."

"Good," said Rarity. "Goodbye, Rainbow. I will write to you when I've had a chance to think things over." She leant forward and hugged the pegasus. "Stay strong. Misery doesn't suit you."

"Heh," Rainbow muttered, embracing gently. "You're too fucking good, you know that?" Her eyes widened suddenly as Rarity's hoof slammed her on the forehead. "Ow!"

"Language!"
