Equine Couples Counseling

A few months ago, Alice had walked in on her husband cheating on her. Not only that, but to make matters worse, the woman he had been buried balls deep inside was her best friend, Jessie. It had been a perfectly normal day. Nothing unusual had happened to make her come home early; no emergencies, no work being cut short, no doctor’s appointments. She had simply arrived home and heard moaning from upstairs.

For a brief moment, she had hoped it was just Jamie masturbating. Sometimes he was loud while doing it, but her heart sank when she stopped to really listen and heard the bed creaking. So, she had walked upstairs, hoping beyond hope that it wasn’t what she feared it was. How was she supposed to handle a betrayal like that?

The betrayal stung twice as bad when she opened the bedroom door to discover Jessie, her blonde and curvaceous friend, one she'd never have thought capable of doing such a thing to her – horny as she tended to be – riding Jamie’s cock and moaning shamelessly, neither of them having realized that she should've been arriving home soon. No, it was the same time she always got home, but they’d simply been too lost in lust to remember.

They hadn’t even noticed her standing there, staring in shock as Jamie came, watching her husband’s traitorous cock throb just as eagerly as it always did with her, not minding that it was buried in someone else’s pussy for a single second. Just as happy to fill Jessie as it was to fill her.

It wasn’t until after their mutual orgasm that Jessie had opened her eyes and let out of a squeal. She had scrambled off Jamie and the two had breathlessly tried to come up with a multitude of excuses, none of which made any sense, and the only conclusion that any of them could honestly arrive at was simply that they’d been too horny to resist.

“For fuck’s sake, you’re not animals, you’re people, you can always resist!” was what Alice had replied with, screaming in a tone so hostile that she remembered the exact words, framed by the bitter sting of Jamie’s infidelity and her friend’s betrayal in her mind.

Well, it had been a few tense weeks after that, with Alice and Jamie barely talking to each other at all during that time. She had considered divorce, until a day spent browsing the internet during a slow day at work had reminded her of something else; couples therapy. That was certainly an option, but she still felt vengeful. She wanted something to really drive home the point that it simply wasn’t acceptable for two adults to “fail to resist” their basic impulses. For the love of god, she thought, she was certain she could choose to starve herself no matter how hungry she was, and the biological imperative to eat was much, much stronger than whatever told Jamie to stick his stupid goddamn cock into her best friend.

And so, she kept searching, until something caught her eye. One of the so-called counseling offices promised to really make the cheating partner – they mentioned that scenario specifically – either reform or, well, accept what they are, with some sort of “self-wrought punishment” suggested by the website.

“Through our program, all participants will be forced to confront their base nature. This is our unique methodology, through which an individual either matures and learns how to control themselves, or simply accepts that they are, in fact, little more than an animal. We consider this a revolutionary new system of couples counseling_,_ and if you’d like further details, please don’t hesitate to visit us in person!”

That seemed interesting, but the description was a little too vague. Alice made up her mind to visit them tomorrow; the place was just on the outskirts of the city, in a big industrial park that had once been farmland. An easy drive, in other words.

She arrived there early in the morning. The place looked a little strange. An enormous, nondescript locale that looked more like a factory building than anything meant therapy. Stranger yet was that next to the place was an entire pasture, turned back into the grasslands it was before, with a whole flock of horses grazing it. Maybe they’re therapy horses, Alice thought, though she’d never heard of horse-riding as therapy, especially not for something as specific as couples counseling.

Inside the building, everything was clinical. It looked more like a processing plant than anything else, but the receptionist greeted Alice with a broad smile of perfect, white teeth.

“Welcome to Equestrian Technologies, how can I help you?” she chirped, seemingly excited to get a visitor.

“Um, I… I read that you offer like… couples counseling? I feel like I must’ve taken a wrong turn,” Alice began, already trying to excuse herself, because clearly this wasn’t the right place.

“Oh, no you're in the right place, don't worry. That's just one of several things we do here,” the redhead secretary laughed. “I'll just make a quick call and have someone come down to meet with you about it.”

Well, that certainly made it sound like they were a giant corporation, and given the mismatched everything so far, Alice wasn’t sure that they weren’t. Soon enough, another woman, this one dressed in a lab coat, exited an elevator right next to the front desk.

After some brief introductions, she explained how the process worked, but warned Alice that this would all be deeply confidential, to the point that she had to sign a long document promising not to disclose anything. Alice felt no particular desire to, and so, she signed it. At this point she was curious enough that she had to know what the hell kind of therapy this place actually used to counsel people.

“Well, the short of it is that we make people confront the animal nature that leads them into cheating to begin with,” she smiled. “Did you see the horses outside?”

“Y-yes, I did, but what do they have to do with any of this?” Alice asked. She tugged a little on her hair. The doctor’s grin seemed almost hungry.

“Well, am I ever glad you asked! Effectively, those that enter our program are faced with some challenges to resist their own sex drives. Each time they surrender to their urges, they will transform a little more to better match what they are on the inside, clearly unable to control their more animal sides,” the doctor explained, and sounded absolutely crazy.

“Into… horses. They transform into horses? Those horses out there?” Alice asked, incredulously.

“Yes, with the aid of a certain substance, ingested beforehand,” the doctor said, matter-of-factly. “Then, if someone is fully transformed, there's still one last chance to reverse what has happened: resisting that animal urge to mate one more time.”

“And… assuming all of that’s true and you’re not pulling my leg, how does that help?” Alice asked. She was getting more confused by the minute.

The doctor raised a finger, tipped with a perfect red nail. “Simple. Should they end up fully transformed into stallions and mares, that’s punishment enough, and after that, they’re also legally my property. Should they resist, we can consider them cured, because they’ve clearly learned to resist their worst impulses. As such, they’re quite unlikely to ever cheat again.”

Alice thought about it for a moment. She really wasn’t sure how to feel, but if it was true, it’d be a great opportunity to give both Jamie and Jessie a little moment of introspection.

“So, in other words, I could… well, right, so I had my husband cheat on me with my best friend. Could they both come here and get treated?” she asked.

“Yes. With the caveat that you’ll also be treated, assuming that they won’t be fully informed of what’s about to happen,” the doctor smiled. “But I doubt resisting carnal impulses will be much of a problem for a woman of strong will like yourself.”

“Why would I have to participate?” Alice prodded.

“Well, you’re just as involved as they are. It’s only fair that every person in a situation like this participates in the treatment. It’s hard to do a proper counseling session without everyone being here, after all.”

“Oookay. So, we all come here and risk being transformed into horses,” Alice asked, one final time. The more she thought about it, though, the more it seemed like a suitable punishment for Jessie. Jamie could probably resist, but there was no chance in hell that Jessie could do it.

And so, she’d inevitably end up as a horny, pregnant mare, which seemed more than appropriate given what she had done. But she needed proof, and told the doctor as much, suggesting that she had to actually see a human transformed into a horse before she’d give them any of her hard-earned money.

“Understandable, entirely understandable,” the doctor laughed. “If you’ll just follow me; we have one man here who wanted us to help him deal with his own urges. That’s also a service we provide, on that note, if you happen to know anyone.”

Alice didn’t, but she followed regardless, her curiosity quite piqued.

They entered a side room that looked something like a very large interrogation room, with the room divided by a reflective surface that Alice instantly knew was a one-way mirror, and sure enough, when the doctor flipped a switch, it became see-through, at least from this side.

She was greeted by a shocking sight. On the other side, a man stood there in front of a breeding rack – the mountable kind they used to collect sperm from horses – seemingly lost in thought. Him being naked and rock hard was already a little jarring; what was more so was the fact that he didn’t have a human cock. No, from the nameless man’s crotch jutted a massive horsecock. Black and pink, mottled, and with the characteristic flared tip.

“As you can see, he’s already indulged a little. We tend to offer a variety of temptations through a variety of means. Right now, his temptation is whether or not to use that device to masturbate himself to orgasm…” the doctor explained. She seemed almost giddy. “…while we pump low-concentration aphrodisiacs into the air in there.”

“How- how’s that supposed to… I mean, I guess, testing his resolve?” Alice stammered. She couldn’t take her eyes off that massive shaft. “Is this what you’d do to Jessie and Jamie too?”

“Jessie and- oh, your partner and friend. More or less. They can changed to horses of either gender, though this one is clearly going to be a stallion. Sometimes, the women end up as stallions, and the men as mares. We change it up based on what is likely to have the best chance of success, up to and including light applications hypnosis.”

The man approached the rack, bench, whatever one might call it. His cock throbbed. Seeing it all unfold in perfect silence from behind a mirror was eerie, and yet, rather erotic.

“What happens if he does it?” Alice whispered. She actively chose to not think about the warm flushing sensation rushing through her and settling in her loins.

The doctor replied with a little shrug. “If he does it, he’ll lose a little more of his humanity. We can’t be sure of exactly what, but certainly something. After all, this should be easy for a functioning adult to resist, no?”

“And then it’ll just continue like that,” Alice continued.

“Until the final test, correct. There he’ll be introduced to a mare when he’s fully a stallion himself. And if he still fails to resist, it’ll be lights out for his human mind, more or less.”

Alice felt a little sorry for the man, but then again, the doctor was right. He should be able to resist, and easily at that. No matter how horny Alice was, she’d never just pick up a dildo and start fucking herself in front of observers. Certainly. she wouldn’t offer herself to get fucked by a goddamn horse, even if she was a mare. Just the idea was ridiculous, but the thought of making Jessie suffer that fate was delicious.

In fact, the idea was so pleasant that Alice booked an appointment right then and there. The doctor reassured her that her “friends” would be lured or fetched to be there, which sounded an awful lot like kidnapping, but it was all for the best, wasn’t it? Their best, that was, and maybe in Jessie’s case, also for Alice’s own amusement.

That was, of course, assuming that all this wasn't just a giant, elaborate scam they were pulling on her, which was a distinct possibility. But the man with the horse cock looked real, and as she turned around to leave – about to return for “treatment” tomorrow – the last thing she caught a glimpse of was the man sliding his cock into the breeding mount.

So much for his self-control, I guess, she thought. Are most people really that weak-willed?

Though for as much as she positioned herself to be clearly above it all, she couldn’t really stop thinking about that stranger’s cock. It was so much bigger than a normal, human one. Surely demanding to have, probably ecstatic to take, but she refused to let the fantasies continue beyond that, willing that beautiful, dominant shaft to remain an isolated thought rather than part of a fantasy where she…

…Alice shook her head. Tomorrow would finally be her day of reckoning.

She didn’t mention anything to Jamie, trusting that the people she had hired would do their job. And sure enough, when she woke up on her side of the bed, it was to the realization that he was not in bed at all. And he hadn’t been, it seemed; the house was quiet, as if he’d been silently spirited away in the middle of the night, or maybe even before he got home. Jessie hadn’t paid much attention to him recently, so she really couldn’t be sure.

Still, that was a piece of good news. Quickly, Alice got dressed and got into her car, to drive down to the counseling office… factory… location. Location sounded like a good word for it.

“Oh, you’re here. Great, we were starting to wonder if we’d have to fetch you as well,” the receptionist greeted her.

“Um, of course I’m here. I mean…” Alice began, only to trail off. She was getting a sneaking suspicion that she was getting herself into something more than she’d thought. But then again, she was hardly going to succumb to whatever they tried.

She was led into the same room as before, only this time it was to an even more exhilarating sight. Jessie was already behind the glass, only she was both naked and tied to the breeding mount, currently struggling. Jamie was next to her, equally naked, nervously fretting about whatever he was supposed to do.

“We’ve already gotten all the preparatory work over and done with,” the doctor explained. “Jessie there was less than cooperative, hence the restraints.”

“O-oh,” Alice replied. “What’s… going to happen now?”

“They’ll be subjected to aphrodisiacs – which you will be too, soon enough – and most likely horny out of their minds. Now, we simply see how things progress. Let’s go in and meet them to really start this session,” the doctor spoke calmly, before donning a gas mask and securing it around her face.

Upon seeing Alice’s worried expression, she continued. “Oh, don’t worry, the aphrodisiacs are entirely safe. I simply can’t be afflicted by them while working, or the results won’t be accurate. I have to maintain a certain objectivity, after all.”

Alice didn’t really like the idea of having to subject herself to whatever was happening in there, but it was part of the deal, and they quickly entered the other half of the room through a surprisingly elaborate airlock system. The moment the door opened, a rush of warm, sweet-smelling air tingled with a lustful kind of musk washed over them.

Of course, the doctor was protected from it. Alice wasn’t, and she had no choice but to keep breathing. At least she didn’t notice any immediate effects except her nose tingling a little.

“Oh god, they got you too?” Jamie exclaimed upon seeing her enter. “You gotta help us get out of here, it’s-”

“No, no,” the doctor commented. “This is all part of the process. This is how you form a healthy relationship with each other.”

“…Alice? What’s she talking about?” Jamie asked.

“Now, now, conflict can wait for another session. Your wife was simply concerned about a certain affair that you’ve had…” the doctor began to explain.

Jamie’s expression went from shock to anger and then back to shock. Apparently, he and Jessie had been kidnapped for counseling, only in the strangest possible way. It felt like his brain had just crashed, and the sweet scent in the air didn’t help.

“In short, this is a test to see if you can resist your most base instincts. Consider it a type of training, perhaps, so that you can repair your relationship. Now, simply, do what you deem appropriate,” the doctor suggested with a sly half-smile. “We’ll keep you here for a total of twelve hours.”

Twelve hours, with aphrodisiacs? That seemed impossible, as if they wanted them to fail. Jamie wanted to argue, but his mind kept getting drawn to other things. There was the fact that Jessie was right next to him, naked and tied to some strange bench-like thing. There was the scent in the air that seemed to rush down to his cock, leaving him more and more aroused. And then there was Alice, who was currently stripping at the doctor’s orders.

It’d be hard for any man to think clearly in that situation, he reasoned, feeling his cock swell. He wasn’t sure what the point of the whole exercise was, but at the same time, he couldn’t really complain either, could he?

He screwed his eyes shut, trying to clear the growing fog from his mind.

Jessie was whimpering. They’d gotten her first, and so, she had been exposed to the aphrodisiacs the longest. At first, she had struggled and screamed, trying to get out, but even more so than Jamie, she was starting to find it increasingly difficult to focus on anything except how good the smooth leather of the bench she was tied to felt. She was already soaking wet, her clit aching to be touched. But hadn’t that doctor told her to resist her urges? What did that even mean?

Would it be “surrender” if she grinded against the bench, just a little bit, to maybe regain some focus? It couldn’t be. She meant that they couldn’t fuck each other. That had to be it.

At the same time, she really didn’t want to – in particular because she heard Alice’s voice and knew that the bitch was looking at her – but her body was trembling with need, and she knew that she wouldn’t be able to focus on getting free before she did something about it.

So, hips nudged forward ever so slightly, rubbing her stiff clit against the leather and leaving a wet trail of her arousal across it. A moan escaped her lungs despite her best efforts; whatever was in the air had her entire body so hypersensitive that even the slightest touch felt amazing, and it reminded her a little of when she’d first learned to masturbate.

“Here, for example, we can see that Jessie lacks willpower,” the doctor smirked, keeping a keen eye on all three participants, but quietly enough so that Jessie herself didn’t hear it, so as to not break her out of her momentary lapse in judgment. “We should be seeing some effects momentarily.”

Sure enough, with Jessie rocking against the leather, her clit swelled bigger than it ever normally had, from a little nub to something much more pronounced. What she couldn’t see was that the bench had a hole in it just below the part she was grinding against, designed to collect the cum of stallions, and her growing clit suddenly caught on it and sunk inside.

Jessie let out a dissolute moan as her clit was suddenly engulfed from all sides by something slick, and thanks to her own body heat seeping into the mount, warm.

“W-what’s happening, exactly?” Jamie asked.

“It seems she’s trying to take the edge off. I don’t blame her, without any protection like this gas mask, resisting it can get pretty hard. Maybe if you help her do it, she’ll be back to normal?” the doctor lied, in a tone suggesting she was asking a question. Alice knew she wasn’t, but said nothing, especially seeing her husband’s cock sticking out, hard to the point of dripping as he watched her Jessie squirm and moan, overwhelmed by the sensations.

“I… I don’t know how,” he suggested. “A-and with Alice here I really… really can’t.”

“Nobody’s judging you here. This is counseling, after all,” the doctor replied.

Alice kept her mouth shut. She wanted to see what the two idiots did without her telling them what to do. Clearly, Jamie hadn’t listened to anything she’d told him anyway.

That said, she was starting to feel more and more worked up with each breath she took of the aphrodisiac-laden air, and her gaze kept slipping, first to Jamie and his throbbing cock, and then to Jessie humping against the mount with increasing need. She did look pretty hot like that, completely at the mercy of her changing body.

Just then, Jessie pulled back a little too far and slipped out of the toy. Alice and Jamie let out a simultaneous gasp as they saw what had happened; it wasn’t a clit that came out, but a full, heavy-looking horsecock, just like the one Alice had seen on the other previous “patient” yesterday. Jessie let out a frustrated whimper, complexly unaware or uncaring that she suddenly had a cock affixed to her crotch, only trying to thrust it back into the sleeve’s warm embrace and failing, unable to pull back enough to place herself at the entrance with her hands tied.

“That’s… wow,” Alice whispered. If her gaze had been slipping to inappropriate places before, it was practically glued to one, now. Jessie’s new cock looked so imposing, and her almost blank expression, twisted by pleasure, made her pleasure obvious. Briefly, even she – ever faithful as she was – had the invasive thought of getting fucked by that thing, but despite her growing need and wetness, she dismissed that thought. If she did, she’d be no better than her husband and friend.

But fuck, it looked incredibly hot, and Alice could only imagine how good it’d feel inside her. Fantasies, though, weren’t cheating. Nobody could avoid those errant sexy fantasies.

“Looks like she’s having some trouble. Whatever might happen if she doesn’t manage to put it back in?” the doctor remarked. She moved to lean against the mirror-window, where Alice had no idea if anyone else was watching, and her expression – going by her eyes, which were the only part that Alice could see through her mask – looked rather bemused.

“I, uh, isn’t the idea to not give in to urges?” Jamie choked. He felt suddenly jealous at just how damn hung Jessie was, dwarfing his own meager human cock. It wasn’t as if he was small, but he wasn’t horse-sized. She might have lost her pussy – there we only a pair of balls that also looked far bigger than Jamie’s – but that cock seemed to more than make up for it.

A terrible idea dawned on him. He was pretty sure he was supposed to resist, yes, but if a slight indulgence had given Jessie a cock like that, maybe it’d be the same with him. Just a huge cock, and then he could go back to not doing anything until their time was up. Maybe it’d even be enough to make Alice want to fuck him again… though mostly, of course, it would be for his own ego. He could just imagine the eyes of every woman with that kind of bulge in his trousers, the wide-eyed lusty stares when he actually pulled it out, and he rather liked it.

A little change. And that’d be that.

He stiffly stepped closer to Jessie. “I’ll help you,” he said, and then knelt next to her. It was hard to believe that massive cock of hers was even real, but it looked real, throbbing just like a normal equine cock, a trickle of precum oozing from the flared head, and when he finally worked up the courage to wrap his fingers around it, it felt warm. No, it felt hot.

Slowly, he guided it towards the opening in the mount, which was made difficult by Jessie mindlessly thrusting into his hand, whimpering – or maybe, though it didn’t register to him, whinnying – as she desperately tried to reach some kind of release.

As Alice watched, she noticed Jamie’s cock swelling the instant he got to work. The first sign was the normal pink color growing black splotches along his length. She almost wanted to warn him, almost, but then again, if she was to stay with him, a bigger cock wouldn’t exactly hurt, Alice thought, as she tried to justify her actions. Her shaft kept slipping in his hands until he tightened his grip, drawing a moan from the changing Jessie as he did, and finally smushed the broad, distinctly nonhuman tip against the convenient slit in the mount’s sleeve. Jamie felt something like a painless sting in his crotch as he first surrendered to his urges, and both his heartbeat and breath quickened as he realized that he’d soon be sprouting a huge horsecock of his own.

Jessie knew that she shouldn’t thrust, because everything was starting to feel different. The colors of the world were changing, red and green tones fading in favor of blue and yellow, and the heavy weight between her legs felt unnatural, but oh so very, very good. But she couldn’t stop now, could she? If she did, she’d never be able to think clearly. And so, she thrust her increasingly powerful hips again, sinking her new cock hilt deep into the provided, tight sleeve, and it felt like her mind melted at the feeling, driving her to keep fucking it, harder and harder.

In fact, Jessie felt powerful fucking the toy. She felt better than ever. Potent, virile, all her intelligence bleeding out and becoming something else. Animal instincts, lust, strength; the transformation that had been kicked off by her surrender was quick, merciless, and ecstatic. She let out a whicker as those increasingly welcome instincts spurred her on.

She found that her feet kept slipping on the floor, each making a clopping sound as she tried to brace herself so she could thrust properly. And she couldn’t quite find any grip with her fingers either; her hands felt thick and clumsy, like…

…Jessie opened her eyes. Her hands looked more like hooves than anything, and part of her vision was blocked by an equine muzzle. She turned to look at Jamie, Alice, and the doctor, who all stared at her with some mixture of arousal and fear, or in the doctor’s case, scientific curiosity. Well, fuck them. She felt fantastic. The toy around her cock felt too good to care about their shocked expressions, or the fact that Jamie couldn’t help but rub his own, growing cock. She didn’t need him anymore anyway, not when her own cock felt so fucking good. And so, she kept fucking the mount like a proper stallion as her breasts melted away, the tissue absorbed to form strong, equine muscle.

At the same time, Jamie was already changing, too. At first, he had grown just a little, but the instant he began to really swell out in an equine shape, he found himself unable to not touch himself. It just looked so sexy, demanding and powerful that his fingers were soon wrapped around the thick length, shamelessly stroking himself in plain view of everyone else in the room. And he couldn’t stop, his hand following the same rhythm as Jessie’s thrusts.

Jessie barely looked human anymore. More like an anthropomorphic horse, with her breasts shrinking away and her arms growing into a pair of equine front legs as she fucked the mount beneath her. Her new, heavy balls bounced with each buck of her hindquarters, and they, along with her cock, were controlling every movement.

Just a… just a little more, Jessie thought, dimly. Her, no, his thoughts were fading, but he just needed to cum and everything would be alright again. Just one orgasm, one big orgasm to pump his newest mare full of his seed, knocking her up. He wasn’t really aware that it was just a mount, a sleeve to collect his cum. Not anymore, with his mind dimming into a purely animal state that’d end up permanent when he squirted out all the errant thoughts that remained with his approaching climax. Just a few more thrusts.

“Right. Now, I’d like some input from you both,” the doctor suddenly spoke up in her first actual attempt at counseling since the session had started. “Sit down, get comfortable, and discuss. What are your frustrations with each other?”

That caught Alice and Jamie off-guard. Both had, at this point, assumed that it’d all be entirely wordless. But instead, they obediently sat on the warm floor, still fixated on Jessie pounding away at the toy.

“Well, it’s the whole cheating thing for me,” Alice sighed.

“It’s um… I mean… I guess I haven’t gotten as much sex as I’d like…” Jamie began, though he kept stumbling on his words thanks to his swelling cock demanding more and more attention, drawing focus away from his logical side.

“I don’t agree,” Alice frowned, at which point the doctor butted in again.

“You could give him some now, you know,” she smiled, or at least, it sounded like she smiled.

“I mean, I c-could, but,” Alice paused, turning her head to look at Jamie’s cock again. “Wouldn’t that count as… giving in?”

She glanced at Jessie, her former friend just about to reach her – no, his peak – looking just like a regular horse now, though with human eyes glazed with lust.

“Not for you,” was all the doctor replied. “He’s the one who wants it, after all, so consider this part of your therapy.”

“Um, I guess I could…” she hesitated, but that hesitation didn’t stop her from grabbing Jamie’s cock. She felt a little better about it now that her “competition” just about to eliminate herself, himself, itself, whatever one wanted to call Jessie now. And so, she gave Jamie’s cock a firm pump from the flat head all the way to his enlarged, horse-sized balls. He responded with a stuttering moan.

Just then, Jessie finally reached his peak. It was glorious. With a final, mighty shove, the new stallion drove himself all the way into the toy’s tight, warm fucksleeve, and erupted. His eyes glazed over, and both Jamie and Alice watched silently as they changed. With each heavy pulse of his cock – they saw a good bit of backwash splash over his balls, white and plentiful – they changed a little more. From a pair of attentive human eyes to the dull ones of a horse, from blue to brown, and from round, and dilated pupils to flat ones. There was, as much as a horse could ever express it, an expression of fading bliss, or at least, utter satisfaction.

All the while, Alice kept absentmindedly stroking Jamie’s cock. She couldn’t take her eyes off the stallion now slumped on top of his new favorite toy, and neither could Jamie; though for him, this was already his second indulgence, his second surrender to lust in a vain hope that he’d get to actually cum.

“Well, that’s… something, is she just going to stay like-” Alice spoke, only to be interrupted by a painted groan from her husband. He doubled over, a gush of precum running down his length, as he began to change. More of him than just that beautiful cock, that was. Alice gasped in shock as his bones twisted and reformed while he squirmed on the floor, fully erect cock still bobbing with each thrashing motion.

“I suppose you were right,” the doctor quipped. “He really can’t resist even the slightest temptation, just like an animal. Maybe he’ll be happier as one.”

“Y-yes, but… I mean, is he stuck like this? Is she?” Alice asked nervously.

“She is. He isn’t, yet,” was the reply, with no further detail. It left Alice only able to watch as her husband slowly transformed into a horse. There was something rather sexual about it; the way his muscles rippled, the way he began to grow fur in pulses, seemingly timed with each throb of his cock. She could only imagine how it’d feel; good, maybe, given his moans of pleasure, even if they were starting to sound more like whickers and whinnies, his elongated mouth no longer able to form the typical human sounds.

For some reason, being proven right brought her no pleasure. But it did bring lust; a somewhat schadenfreude-tinged lust that almost made her rub herself right then and there, not helped by the aphrodisiacs that had her slit burning with desire and her mind already halfway as clouded as that of the new stallions. Jamie slowly struggled onto all four legs, giving Alice a pleading look.

Even now, he was apparently only concerned with getting off. His cock jerked, splattering the floor with another hopeful squirt of precum, and he stood right next to her, unmoving. Alice couldn’t help it. Try as she might, she was getting horny too, especially as the two stallions, with whatever human intelligence those dull eyes of theirs still possessed – Jamie much more so than Jessie – stared at her hungrily. Those beautiful, enormous cocks. Would she grow one too, if she indulged? The doctor refused to answer anything she asked, choosing to only observe.

Wasn’t the experiment already over, anyway? Both her friend and husband had succumbed. Why weren’t they letting her out?

Something warm and powerful rubbed against the side of her head. Jamie’s cock. He gave a pleading whinny, as if begging her to touch it, to give him the same kind of relief that Jessie had gotten. It wouldn’t really help him, destined to be a stallion stud as he was, probably constantly horny, but maybe it wouldn’t hurt to give the man she’d once loved a final moment of pleasure.

That, and she really wanted to. Just this once. Maybe her clit would grow a little, and that’d be that. If she ended up with a cock, she’d just turn to making money with photos of it online. There was no way she would go any further than that, was there? The first time, nothing had even happened… that she knew of, anyway.

Just one little touch. One little rub. She was soaking wet at the idea, painfully aware that her juices had been dropping down her legs and slowly pooling on the floor. Besides, it wasn’t even cheating, the horse was – to some extent, anyway – her husband, and who could judge her for giving her husband a handjob?

There was one little detail that the good doctor hadn’t told any of them. The process was rigged, and it was only gradual in the most literal sense. The transformation really only had a few triggers as a “patient” surrendered: one for any sexual contact, one that resulted in quick transformation for further indulgence, and a last, irreversible one, should they reach orgasm after the change. Perhaps it should’ve been obvious to Alice, but she was far too horny to think straight, and Jamie equally so, while also incapable of speaking at all.

The main difference? The first time, he had asked for it. This time, she was doing it because she wanted to, which was far closer to that instinctive, animal state that had already claimed Jessie, who now stood watching them, fully erect but evidently docile, not really registering whatever it was he was looking at.

Holding her breath, for all the good it’d do her, the unsuspecting Alice couldn’t resist. Gingerly, she wrapped her fingers around Jamie’s shaft, marveling at how deeply erotic it felt against her digits, how it throbbed against her palm. And at that moment it was too late for her. A jolt of pain at the base of her spine signaled the beginning of her transformation, and she groaned, barely able to even hold on to that majestic cock as her body shifted.

It felt quite wonderful, bar for the jarring cracks and quickly dulling pain as her spine rearranged itself into a more quadrupedal form, and even then, the feeling of pure power surged through her and numbed that pain. In a breathless, feverish state, Alice leaned in to kiss the tip of her former husband’s cock, her tongue scooping up precum as it danced across the slit at the very tip of his flared glans. He let out another needy whinny, stomping his hooves and wanting more, but Alice had no time to bring him anywhere close to orgasm.

Don’t panic, she told herself as her hands slowly lost articulation. Just relax, chill out as a horse for a bit if that’s what’s happening, and then you’ll be back to normal. Oh god, what have I gotten myself into?

The transformation washed over her violently but not painfully. Her vision swam as the world was suddenly drained of the colors that a horse couldn’t see, while all sounds grew sharper and louder in her changing ears; the same ears that were slowly pulling up to the top of her head. Chestnut-brown fuzz was beginning to cover her exposed skin, just like it had with Jamie, only this time she had no choice but to look and feel it happen.

A series of pops that felt like they were supposed to be painful but weren’t followed as she fell firmly on all fours, unable to support herself on only her legs. Her back legs, she realized. And there was that sense of power again, power and lust, carnal and primitive. Like this was a desirable thing, all the worries of the modern world falling by the wayside with each shifting limb, each spark of burning need in her womb, and each muscle growing into a more powerful, equine form.

A tail burst out from the base of her spine and its long hairs brushed over the particularly sensitive, swollen lips of her pussy. Alice tried to turn around and look, but found that she’d lost much of her flexibility in favor of strength. There were no mirrors, but she could only imagine herself having the cunt of a mare now, constantly on display with no clothing to hide it. And even that made her shudder with a kind of perverted, nasty pride. After all, why shouldn’t she show off? She was becoming increasingly more beautiful and less concerned with whatever humans considered important.

At the same time, she was fading, or at least her mind was. The anxiety of being trapped here and subjected to this counseling was fluttering away like leaves in fall. It was liberating; the whole world – or most of it – existing only in the now, as she stood up again, this time on all four legs, and sniffed the air, catching the most intoxicating blend of stallions and virility.

The influx of sensations left her dull mind completely stunned for a moment. Her body reacted to it without any conscious input, though; her tail swished aside, and she could feel a heat in her lower belly. There was no mistaking what that meant: arousal. Every mammal, she thought, probably felt it roughly the same way. The difference was in their ability to process it or resist it.

She stood there, still thinking somewhat like a human would, but unable to articulate any of it. Her deep, wide mare-pussy ached to be filled, and she could feel it wink – she knew it was called that from her brief time helping on a farm – as her need grew totally overwhelming. But she could resist, couldn’t she? Just stand still. Don’t do anything. Don’t look at those beautiful cocks or imagine yourself as a blissfully dumb and pregnant mare.

But then, Alice saw Jamie’s nostrils twitch. He still had that dim but human look in his eyes, but his cock jerked again, not having been granted any relief instead of the merciless teasing of his transformation and the little touches the doctor had suggested he’d get. And so, driven by lust more than self-preservation, he slowly trotted out of view and behind Alice. She was about to run away, but in an instant, the doctor was beside her, soothingly running a hand through her mane and over her snout.

“There, there. No need to panic. You want to be bred, don’t you? You don’t even have to do anything. Just stand there and let it happen, just the way a needy mare like you wants it to,” she coaxed her. But Alice knew she shouldn’t. She flicked her tail, stomped with her back legs, and thought about kicking but reconsidered, not wanting to hurt her husband.

Then she felt his warm breath on her leaking pussy, and she realized that she had to move, and yet she didn’t, not even as Jamie stuck his snout just against her clenching, winking sex and breathed in her scent, getting himself even more drunk on lust to the point that all the human thoughts in his head took a firm back seat to the burning lust.

“This is what you want, just what you both need to be a happy couple again” the doctor whispered while Alice shifted nervously. Jamie wouldn’t just fuck her like this, would he? He’d been many things, and a cheater at that, but he’d never fuck her without asking first. “Stay just like that. Give him the sex he wants, and I promise you that you’ll both be happy again.”

Give him the sex he wants? Just the idea of it made Alice wink again, lewdly. This wasn’t good. She had to move no matter what the doctor said, but it was as if her body had already decided what was going to happen. Her conscious mind failed to move any of her four legs in any significant manner. Fucking move. Move! Animals can go against their instincts, just look at dogs. You’re smarter than a trained dog!

But just as she was starting to override her treacherous, needy body, Jamie reared up behind her, and his full weight landed on top of her. No! Alice didn’t want to succumb, not like this, but with a stallion weighing her down she had no chance of escaping. Maybe she could kick him off, but that’d risk hurting him! She let out a panicked whinny in what she was afraid would be one of her last moments of human consciousness, and not only hers, but Jamie’s, too.

He thrust blindly, painfully jabbing his cock everywhere but where it was supposed to go, and she endured it, hoping that he’d get discouraged. But her counselor had other plans.

“Stay still, I’ll help him. Good girl,” she murmured.

She walked around her, disappearing from her wide equine field of vision. Alice knew exactly what she was doing; Jamie had just helped Jessie with that earlier, and seconds later, her fears were confirmed; she felt the damned doctor position Jamie’s cock just against her slippery, eager entrance.

“And now thrust,” Alice heard her voice. “If you’d like to, that is. Just remember what it means.”

That last part sounded practiced, as if she had been told to say it by whatever HR this strange company had. As if that made what was happening to them any more legal. But Jamie, horny out of his mind and with his inhibitions further frayed and muted by the transformation, took her advice and thrust with a wild nicker. He sunk deep into Alice’s body; flare and median ring both popping past her unresisting folds, and then rest of him, until those heavy equine balls slapped against her.

Her eyes went wide. Yes, she’d expected it to feel good, but it felt far better than she could’ve imagined. Like her body needed it, like his cock was scratching some itch inside her. Her inner walls molded around her stud's cock, perfectly hugging every inch of him. It felt sexy, it felt pleasurable, it felt affirming, like when she was ovulating— wait, was she in heat? She’d get pregnant!

And if she came, if she understood how this worked, she’d be locked in this form forever. What would even happen if he bred her, but she didn’t cum?

But all those worries were instantly gone when Jamie, using his new body, thrust properly for the first time. Her anxiety melted into carnal joy, her body responding fiercely as he began to hammer into her sopping mare-cunt, completely uncaring about what’d happen to him – fully caught in the iron grasp of animal instinct – and wanting to, at least unconsciously, bring her down with him.

Each thrust was like heaven. The way his broad cockhead seemed to dig into her inner walls and rub against pleasure-spots that she didn’t even know she had. Her body cheered him on, urging him to thrust harder, and he did, soon fucking her with his full stallion strength, utterly caught in the moment and spurred to push on towards the demise of his human self by every sweet clench of her deep, willing pussy. Alice was shivering, his hind legs soaking wet with her juices, as she was pushed closer to some until-now unknown peak of pleasure by his rutting.

To her relief – and to some level, dismay, too – it wasn’t long before Jamie suddenly reached his peak, driving his massive cock as deep into her as it’d go and surrendering to the pleasures of her pussy, suddenly erupting in a flood of thick stallion-cream pumping deep into Alice’s body. She snorted and shifted, wishing she could’ve gotten away as the heat blossomed inside her, but at the same time, it felt so very, very good.

“Good girl,” the doctor murmured. “But you should really let yourself enjoy it, too. Let go of all that tension and jealousy and just be what you want to be. You can’t really be a good couple if only one of you is a big, dumb horse, after all.”

Alice snorted again. She shook her head. She had gotten this far, and though her body was burning with a need for that promised release, to the point that even her strong legs could barely keep her upright, she wanted to outlast this. No matter how frustrating it was. Unlike her friends and apparently husband, who was now slumped on top of her with his eyes faded to those unexpressive equine ones, all thoughts gone with the seed he had squirted into Alice’s womb, she knew she had the self-control needed to resist this. God, he really was gone, just like that, and slowly pulled out as if nothing was wrong at all, leaving her leaking and his balls very satisfied.

The doctor, though, did something she wasn’t expecting. She walked over to Jessie, once again well outside of where Alice could see, and untied him from the mount before leading him over to Alice.

“Maybe your husband just can’t pleasure you,” she spoke softly. “So how about you give him a taste of his own medicine?”

No was what Alice wanted to say, but her body said yes the instant she felt Jessie’s lips against her cum-oozing sex. This time it didn’t just feel good; there was that jarring feeling of knowing that it wasn’t even her husband, just a horse that’d once been her cheating best friend. Jarring, but delicious, like the sweetest fruit. The aphrodisiacs and her reduced agency both enhanced it further, coaxing the flame of need into something overwhelming.

She tried to protest but only a neigh came out, and if anything, it seemed to register only as encouragement to the former woman. Jessie reared up in turn, entranced by Alice’s scent and the inviting, half-gaping relaxation of her pussy, and mounted her in turn. He didn’t need to be guided in, having already had some experience with the toy, and his cock pressed directly where it wanted to go. Once again, Alice’s body offered more encouragement than resistance as the second stallion slid into her effortlessly.

By now, she was quaking. It was close. Even if Jessie didn’t take long – which she wouldn’t, being little more than an animal trying to breed her – she was close, perilously close, especially from knowing that the cock inside her belonged to someone she not only didn't like, but someone she'd never even thought about fucking before. Her body certainly liked his cock, and the forbidden pleasure of letting someone else fuck her had her panting, snorting, and whinnying as that fire was suddenly stoked again the moment Jessie began to thrust.

Maybe she wasn’t any better than them, Alice realized, as the ecstasy once again built toward a blissful climax. Maybe she had wanted to do this all along, maybe she was just an animal, and maybe she should just surrender. Not that she had much of a choice; those thoughts were, perhaps, a last-ditch effort to excuse and justify what was about to happen as her insides coiled up, the tension building as her body slowly surrendered to the inevitable.

Her belly muscles contracted as her pussy tightened around Jessie’s pistoning shaft. This was it; she couldn’t hold out. Want it or not, she was going to cum, and the worst part of it was that maybe, just maybe if it was involuntary, she wouldn’t change. But she did want it. Every fiber of her being did; what approached felt like the orgasm of a lifetime, of finally letting go of everything and simply existing in a roaring moment of convulsing, white-hot pleasure.

Just the way it was meant to be, getting rutted by a stallion who had simply mounted her without any words, without any seduction beyond what their bodies mutually needed.

Fuck.

I want it.

She exploded into ecstasy. The finality of it all made it stronger. Her pussy gushed around Jessie’s cock, betraying whatever little faithfulness she had left towards her husband, and that set off a chain reaction of the last changes she’d experience.

In that single beautiful moment of orgasm, everything changed. Alice tried to hold onto her mind as best she could, but it melted and fell apart, slipping through her attempts to hold on like sand between her fingers. As if her clenching, milking pussy was not only draining her beautiful stallion’s cock, but her mind as well, memories disappearing one by one with each squeeze until she could barely remember what her name was.

But it wasn’t terrifying. It was the opposite; it felt like freedom, even if she was only tangentially aware of what freedom even was after a few moments of cumming her brains out around her stud’s shaft. It was liberation, and it only felt better with each passing moment, her orgasm intensifying to the point that she was whinnying while getting seeded, all hesitation transformed into ravenous, glowing need in her womb.

She reveled in it, loved every pulse of pleasure that further wiped her mind clean and left only that animalistic, primitive purity; lust and hunger, and little else. Her milking quickly brought Jessie to orgasm as well, and he neighed as he filled her womb with another potent load of stallion cum, marking the first time since Alice had gotten together with Jamie that she'd let anyone do it. She’d abhorred the thought, but suddenly, it felt so goddam good, so pleasurable that she couldn’t think, and never would be able to again. Not beyond her immediate needs, anyway. Her body drank every last powerful spurt, letting it fill her womb, his swimmers swarm up her tubes where they’d knock her up if Jamie hadn’t already managed to.

Oh, it was beautiful. No more worries. No more anxieties. Only pleasure. She surrendered, letting the ecstasy pull her down into sweet, dimly-lit near-oblivion, a twilight state that she’d spend the rest of her days in as a happy, well-bred broodmare.

Just as Jamie’s had, when Jessie brought her to orgasm, her eyes dulled, losing that human attentiveness, but with it, also the capacity to worry like humans did. She was getting bred, and that was good because it was what she wanted. No longer would she feel jealous that her stallion bred others, because it didn’t matter to her, as long as he put his foals in her belly, too. She was past the point of really understanding anything, but on some core level, it finally made sense to her how willing her husband had been to cheat on her. How badly Jessie must’ve needed it, just as she did right now, compelled to remain as still as she could to let his seed soak into her, so that she could accomplish her desire to get pregnant, which she had – or perhaps hadn’t, but it made no difference now – always wanted. She was, after all, a broodmare. That was her purpose.

When she, Jessie, and Jamie were led outside after all of that, to the same paddock that a more human Alice had wondered about just the day before, it wasn’t long before Jessie was sniffing at her backside too, wanting and turn at the only available mare in heat. Alice was happy to let him. After all, a good mare shared with the herd.

And so, theirs was another story of successful counseling; all differences, anxieties, and most of all, jealousy between the three reduced to nothing at all, perhaps best emphasized by Jessie pumping another load of stallion-cum deep into her wanting womb, trying to outcompete Jamie in an orgasmic, equine frenzy.
