When a young man gets a chance to volunteer his services on serving as a stud to mares on a new planet, he lunges at it. After all, he can enjoy some of his own deviant pleasure and get paid for it, of course, he really should have read some of the fine print.

"Old earth horses were some of the finest, that's why we're trying our best to revive the species' here on Antheon." Doctor Merrygold pointed out as they walked along the line of the stalls that ran along either side of the massive barn. "Of course, reviving any extinct species has a certain amount of hang ups along the way, more than enough to make it typically too expensive to consider."

Alex nodded his head, an action that should have felt quite natural, well, if he had been in his own body at the time instead of a large horse. Trans-Species Assignment had become the latest rage as the settlers made their home on Antheon. It was a Class 8 planet, one with low level technology that would slowly be weeded out over the next dozen years or so and return to a simpler time. His family had moved here four years ago, an exciting event as a teenager and it was made even better by the fact it had pulled him out of several hard spots from their home planet. It was a new life, a new start, with land enough for anyone bold enough to take it. He had attached himself to the vet program as a matter of course, mostly because he always been fascinated by the old earth species' and even done research on them when he had been quite young. It wasn't that surprising that he had found himself taking on the reassignment of species' when they had put out the call.

Old Earth species' like cows and pigs and ducks and horses had slowly been weeded out as they had spread through to various planets. There were still a few, of course, but the horses were no longer exactly the right species' and shape as they had been before, they had been adapted to other planets and given what they needed to flourish. Here, though, they had a need of the basic equine shape and form without the flashy modifications they gave others. Antheon was very near what Old Earth had been like, complete with a mild climate, lush terrain and a host of continents that were starting to be explored. The idea was to go back to the way things were, to keep what technology made their lives good and erase what caused so many problems from the settled upper Class planets. And to do that... they would need animals to partner them.

"Now, we've had one hundred and four mares brought in, they are blank stock, which gives us a good chance at making sure we begin with what we need, which is typically draft style horses for pulling plows and carriages." The doctor gestured towards the stalls and Alex twitched his ears up expectantly.

Blank mares were mares that had an entirely mutable set of genome. The idea was that a stallion could be brought in to breed them, he would pass on his breed, no matter what it was. It meant that a single breed of stallion could sire entire pure generations with blank mares. Stallions, however, had to be specifically made up to speed. There were no more males that weren't modified in some way, which meant they had to assign a species to people willing to sign up to the program. Alex almost laughed, even though he knew his new mouth and muzzle wouldn't make the shape properly. He was positive that there were quite a few people that would be horrified to be in his position instead of excited.

_I wonder if they'll give me the bulk of the mares to breed? _ He thought idly as he kept up with the doctor, keeping part of his mind on the pattern of his hooves as he walked forward.

Being set as a trans-species meant different things to different people. He knew that at least two other stallions had signed on because they had some sort of disability, something that made their real bodies confining and broken. Being genetically changed gave you a whole new body, everything worked, you stepped from a human form into an equine one. They would do their duty of course, that was what they had signed up for, to breed as many mares as the school needed to birth a new generation, but they wouldn't enjoy it. Not like him. Alex twitched his ears up and glanced at one of the mares who was looking at him with interest, a lovely little chestnut that was nearly as red as a newly minted penny.

Ever since he had started working here he had found himself interested in the animals in a way that would have made most men blush their fool heads off. There was something about the way that the creatures were so simple, easy to understand, they understood what they wanted and would give it freely. He had never had much luck with women, most of them laughed him off as a joke and the rest simply saw him as another face in the crowd, sympathetic, but uninterested in him. A mare had never looked at him as if he were uninteresting, in fact, the mares seemed quite happy for his attention when he groomed them, often winking and flashing him in the most interesting way. Was it so strange that he wished to be one of them? To spend time courting them and enjoying his life playing herd stallion among a group of heated tail raising females?

_Well, I'm sure other people would find it wrong. Thankfully, they will just be too happy to have horses breeding and available for their farms to care who the sire is. _ He thought and flicked his tail, testing out his new body.

"Alright, now come through here. You're the second draft stallion we've had sign up and I want to make sure that you're up to par. The first one had some abnormalities that we're hoping won't be repeated." The doctor gave a little gesture towards an open looking stall that was barren of hay, there was only etched tile to give his hooves purchase.

He twitched his ears back, but stepped forward without complaint. He couldn't precisely remember all that had been done to change him, but he knew that it had involved a good deal of time passing. He had mostly been sedated for it since there was pain involved, but in the end he had woken up and stood up as a horse, a stallion. He wasn't even sure what his Old Earth name would have been, he hadn't really researched that deeply, but he was heavy bodied with a set of thick feathered legs. He was black and white, bold splashes of color ran all along his body and right over his rump, another on his ears. He had stared at himself in the mirror, considering himself and felt only pleasure at the stocky muscular body that now possessed, the thick spill of his mane on his head, the way that it coated all the way down along the line of his neck. He had never moved as easily as he did now, nor as freely, he was a perfect balance of vitality and grace, even his hooves couldn't make him a bit less graceful.

He wasn't that tall, that was his only disappointment. He had imagined himself as a towering stallion of muscle and body, large enough to dominate anyone around him, but he was shorter than he had assumed. He felt the fingers rubbing along the nape of his neck, stroking with a delicate touch that was entirely pleasurable as the strokes rubbed over him and ran towards the sweep of his shoulder. It was delightful, he arched into the touch as he stepped into the stall, his large feathered hooves hitting the ground with a loud clopping noise. Even if he wasn't as tall as he wanted to be, he was still larger than any of the humans. He was still on par with the mares that he was going to breed, they'd still feel so warm beneath him, shivering and arching for his own pleasure. Just thinking about what he was going to be doing with the mares made the tip of his cock start to slither free of the low swinging pouch, drooping it down towards the ground before he contained himself.

"Now, I'm going to have one of the techs in here, we need to make sure that you're set in your changes. Since the mares are blanks, we can't have any inferior genes being used to breed them." The doctor gestured with a hand while Alex snorted, his ears pinning back on his head in annoyance. "I'm not saying you're inferior at all, just that we need to make sure the changes were done smoothly and taken hold of you."

Well that's better at least. _ He thought and shifted, turning about in the stall as the doctor stepped back into the doorway. The stall was filled with the sharp acrid smell of chemicals were on the air and filling his senses. _I wish they'd just let me get used to my body first, or go and flirt with the mares. It's not as if I'm like the other trans-species that need to be worked up just to get a hard on.

"Kimmy, I want you to handle him. Bring the standard restraints, he's newly awoken and he might kick just by instinct." Merrygold smiled at him as he spoke. "Now, you're going to have to submit to a few tests, they might feel strange and a little uncomfortable, but I assure you that you'll get used to it in no time. Afterwards we can go ahead and see about siring the next generation."

_Lovely, tests. _ He nodded his head again in understanding, shifting back in the stall as a young woman came out from somewhere deeper in the stable, her arms full of what looked like ropes and leather bands.

"Oh, he's a handsome one." She spoke up brightly as she stepped into the stall. "Is he the Vanner?"

"Yes, small draft horse, but still very powerful and traditionally a heavy worker when it comes to pull carts and carriages." The doctor agreed and moved out of the way for the girl to come into the stable. "I want you to pay particular care to him, and rig him up in the harness afterwards, we've three mares in season that need to be inseminated."

Alex almost rumbled at that part of the conversation, three mares. He'd always wondered what it must be like for a stallion to have a mare, feeling their feverish bodies parted around his cock as he sank his way home and felt the inner muscles contracting around him with their heat and desire. His tail snapped this way and back behind him as he rumbled and flared his nostrils open wide, just thinking about mares ready and waiting for him. He could feel his cock drooping a bit under him, unable to stop it, and truly not caring that he was flashing it around while he stepped this way and that, tossing his head up as the girl came in close to him with a smile on her face. She was in her late twenties, her face open and cheerful as she reached her hand out to stroke along his cheek lightly, bringing with her the scent of fresh hay and clean soap.

"Alright, I know that you might not like this, but he is right. Your new to your body and instincts are strong, I don't want you to end up kicking me on accident. Neither one of us would enjoy that!" She announced and looped down what looked like a halter from her arm. "Just relax, I've done a lot of these exams, so you know you're in good hands."

_At least she's a girl. _ He thought to himself while hands stroked against him lightly, moving around him with a gentle touch scrubbing over the edges of his neck right near his neck.

He didn't fight when the woman moved the halter up and slipped it along his head with a gentle caress of leather against either side of his cheeks. It felt quite strange to have anything drawn up and over his nose which was so incredibly long feeling. Alex didn't especially like the halter, but he could respect why it was going to be used, he supposed that testing him and looking him over would be more invasive than it would be if he could really speak. Still, the promise of the mares waiting for him kept him still as the halter was buckled on his head firmly and two leads were clipped to either side of his head. There was little to object to, it didn't hurt, it was rather comfortable in fact, but then again it had been designed for him.

He got a glimpse of the girl as she moved behind him, her hands running along his back and side. She had called him a Vanner. He could partially remember something about that name being talked about when he'd signed on, but he was at least reassured that he was a draft style breed. He lifted his head a little bit and tugged at the leads as he considered his stocky muscular body, it really wasn't bad, but his real attention was down beneath his belly. There was a low slung pouch that rested right along the underside of his belly, right near his haunches and tried to admire himself. It was far larger than anything he has possessed as a human, the shape was entirely different as well. He had gotten only a few glimpses so far of the mottled flesh, but what he'd seen he had felt quite proud of , he could see no reason not to be happy with all of the changes that had been made.

He let Kimmy wrap a set of what looked like oversize cuffs around both his ankles, the leather was wider than her hand and well padded as it was buckled down. It was strange, his hind legs had the positions all out of whack, all of the positions that he was used to on his human feet and legs were in the wrong spot. The restraints were wrapped around more what felt like they should be his feet, but in reality his lower legs. She was quite fast as she tugged them firm and stood up, tossing a conglomeration of straps right over his back, some of them bouncing and hitting against his sides with the harder buckles striking him, causing him to turn about with a short snort.

"I'm sorry, it's just easier to get it tossed up like that. Don't worry, it's just going to keep you from being able to kick me, is all." She gave him an affectionate pat and Alex let out a sigh.

_I wish they had left me the ability to speak, or at least manage something like human sound. _ He thought with a touch of annoyance.

The harness that she fastened on his chest and stomach was just that, a simple harness that seemed to have little use save to run a set of broad straps down under his belly and towards his hind legs. There were three main parts to the body of the harness. One went around his neck and shoulders, another wrapped around just behind his legs and over his chest and a third part was wrapped around his haunches. The harness wasn't painful or difficult to wear, it was actually rather nice feeling in some places as the buckles were done up and he did his best to not cause a fuss. The faster he got through all of this, the faster he would be able to get on to the mares that were waiting for him.

As she worked, her hands wandered over his body with a clinical air that stroked along his chest and down along his haunches. He didn't mind that in the least little bit, her touch was gentle and quite enjoyable as he shifted about, tossing his head and swinging his ears backwards a little bit as she even stroked right along her haunches. The gentle rubs trailed down along the base of his tail base and made him shift and shiver in delight at the way it played against him. He flicked his tail up before the girl caught the thick hairs in one hand and pinned it in place, something being drawn out from her pocket as she kept the tail trapped under her arm. He swung his head back to regard her curiously, ears pricked up on his head as she drew out a bright blue roll of sports tape.

"Sorry about this, but you're a bit thicker in the tail than I'm used to." Kimmy apologized and began to wrap the base of his tail.

He wanted to sigh, but Alex only shifted, stomping a hoof a little bit as the long hairs were wound up and gathered right around the thickness of his tail bone, being wrapped and pinned in place. The long strands were carefully pulled and twisted about, curling and pinned under the self adhesive tape that squeezed down against his tail. He shifted and heard the leather creaking around him, sliding along his muscles as his entire tail was worked up and gathered up into a thick club. The human's keen hands were used to wrap it so tightly that it nearly pinched, but it wasn't too bothersome, just odd feeling when the thick club was dropped down along his haunches and bounced against his haunches before her hands began to run down over his legs and more straps were dragged out to run down towards his hooves.

"I'm going to bind these up for now, I don't want you kicking me, and I need to give you a good looking over." Kimmy explained with a smile at him as her hands ran towards his hooves.

He was absolutely baffled about what she was doing as he swung his head around as far as he could go to look at his legs, trying to see what she was up to. The straps were wrapped around the spots just above his hooves, looping over one another and pulling tightly down so that the long straps that hung down from the harness. He let her snap the clips into place, belatedly realizing that they were hobbles that were designed to make sure he couldn't kick backwards. It was slightly alarming to feel himself being snapped into the harness so that he wouldn't be able to fight back with two of his most impressive weapons. It made him lift his hoof up, he tried to push backwards, but the leather went tight only a few inches back and the harness tightened along the side of his back before he dropped it down again.

His second leg was given similar treatment, snapped into place and locked down with the straps above his hoof making him stamp and shudder his haunches. There were a few shudders running down along his sides as his head jerked against the leads while he snorted out and the girl only made a few soothing noises at him and rubbed a hand along his side. He didn't like this at all, being restrained wasn't something he had been prepared for and he didn't like it one bit. His club like tail snapped back and forth against his haunches, hitting back and forth when he tried to step to one side and he felt clumsy as he jerked against the hobbles and blew out a breath, snapping his ears back on his head. The girl kept murmuring softly, the words mostly nonsense as she kept stroking the like of his haunches with a gentle caress.

"I know... I know, it's alright, I know you don't like it." She was saying to him, her hands teasing along his thick mane, tracing one large white patch. "Just relax, as much as you can, I need to make sure you're able to breed a mare."

How dare she!! He let out an angry noise form deep in his throat, almost a squeal as her hand kept stroking along his side.

"You just have to be long enough and large enough, some humans don't change all the way down there to really inseminate a mare properly." She explained softly. "If you stop fussing I can get it over with, you know."

_Not long enough?! I'm perfectly long enough, I saw it myself! _ He thought and tried to still himself, his breathing slowing as she leaned intimately close against him. _I'll have a word with the doctor after all of this is done!

_

Her hands were at least gentle and soft as she kept talking to him, he felt a slight twinge of aggravation that she was talking to him as if he were a horse, but he made himself act calmer and dropped his head down a little bit. His nostrils flared, drawing in deep full breaths as the fingers stroked along his underside and reached further back towards his haunches. He was a bit shocked as he felt the fingers curling up lightly right along his sheath. It was a shock to feel the touch stroking against him, rubbing over the edges and trailing down with a light caress that made a tremor rock down the line of his back. The fingers cupped against the heavy leathery flesh, rubbing lightly along the edges and pulling up towards the lips of the opening as he shifted a bit nervously. He felt a flush running up along the line of his ears at the boldness of what she was doing.

She trailed the touch along the underside of the swinging sac and her fingers curled up and right into the opening, startling him into snorting and shuddering, his ears falling back against his head before side stepping to one side. He tensed himself, jerking a little bit while the hands on the back of his sheath gently began to massage and drag against him, pulling along the low slung flesh and caressing him with light touches that made his body react and shudder. It didn't feel bad at all, it was mildly embarrassing, but that was out shown by the gentle caress that rubbed right under his cock tip and curled upwards, cupping against his sensitive glans.

The new shape was almost frighteningly sensitive to the touch of the fingers curling against him, the mammoth shaft soon began to slither free eagerly into the touch as he snorted and shivered in place, pawing roughly against the ground. The girl was still talking, but it was quite difficult to make out what she was saying when her hands were rubbing up along the emerging length that fell down onto her palm. He had dropped several times before, but it had almost been idle, a spilling free of loose flesh before dragging back into his body again, this time he felt the blood swelling and filling the long girth and making it spread open wider and wider by the moment. He let out a short squeal and shifted, his tail flagging behind him as her fingers closed around him and squeezed.

It was a dizzying rush, suddenly his girth began to harden and slap upwards against the underside of his stomach messily, spilling a wet dribble of precum against him before the girth fell back down into her ground again. Her other hand moved away from his cock and began to slid around his base as it emerged from its home and it jerked upwards with a powerful flex and slap against the underside. He hunched his back forward, a rough jab and drag backwards, his cock drooling out a spill of hot precum onto her fingers and caressed lightly, smearing the wetness against his mottled girth. He pinned his ears backwards, holding them there when she pumped lightly, lifting up his cock before it swung up of its own volition, slapping wildly upon his chest.

The fingers pushed around him, kneading gently as he shifted and snorted to himself, tugging against the leads when her hands began to move backwards towards the low hanging leathery balls. The fingers caressed and danced right beneath the underside of them, rubbing and pushing them up so that she was taking the weight of them in the palm of her hand. It felt good, he shivered and stomped his hoof again, snorting and tried to thrust forward while he let out a hot breath, his eyes squeezing shut while he tried to hump forward again, the wild movements jabbing his cock this way and that, the tip not hitting anything except his own chest as he tried to get himself aimed properly.

He liked the way the hands were rubbing over him, but they were frustratingly inconsistent where they were rubbing at him. Sometimes they teased against him in one spot and then moved back towards his balls again, they were everywhere at once, making him try to find enough sensation to enjoy it, but she moved her hands away from his balls long before he was ready for them to stop. The hand on his dick reached down and gave a light squeeze right against his cock tip and pumped it, causing his haunches to tighten up and jab forward, but it left him as well and he was left dropped and throbbing. He was flushed and worked up, his sides heaving as he tried to surge forward again, struggling against the leads.

"You are at least eager, well nothing wrong with the size." Kimmy reached up and undid one the leads. "Come on, big boy, let's get you ready."

_Finally! _ He nearly dragged her behind him as he surged forward, but was rather disconcerted to find that she forced the chain end of the lead into his mouth and pinned his tongue down like a bit.

It tasted quite foul, making him shake his head with irritation, throwing it this way and that with an effort to clear the taste from his maw, but it didn't seem to want to leave him as he chewed over the chain roughly and rolled his tongue under it. It pinched a few times while she led him from the small exam stall and made him throw his head about unhappily, they didn't have to tie him up and hobble him for being fondled, he would have happily let the girl do that if she had just asked. His clubbed tail smacked against his haunches as he was led out of the barn and out onto the fresh thick grass, his nose picking up the sharp acrid smells of the chemicals being used to terraform the ground to neutralize some of the acids that had been found in the soils.

It was a brief distraction, one that he needed since his cock was swinging wildly beneath him , being flung to either side of his hind legs and slapping up against his stomach at times. It didn't seem to want to go down, not even when he tried to control himself and rein back the desire he felt. The spire had a mind of it's own and that mind was entirely focused on finding something soft and warm to stuff itself into. So he snuffed and huffed the chemical smell, trying to smell the sweet grass beneath it to distract himself. He had never smelled them before, but now they were a source of irritation as he was led to one side and towards a get up that made him stop and lock his legs in place.

It was a chute, a metal one, made and reinforced in every place he could see and seated on a thick slab of rock with points drilled down so that it couldn't be budged. The back end was open, but it only revealed that there was very little room on the inside and the walls were lined with thick bars as if they were designed to be used to snap into place. He gave the girl a look and pinned his ears before jerking his head towards the device that she was trying to lead him too meaningfully. He had no desire to end up in that contraption, but she only pulled at the lead a bit more firmly, trying to get him to go with a tug that pinched the chain on his tongue and he grunted out and kept his legs locked.

"Fine, be stubborn, I told you, we have to check you out. Some of it isn't as fun as you'd like it, that's why you're hobbled, but this will let us get it through easier." She commented and glared at him. "Unless you are planning on spending the day with me trying to get decent readings and want to spend tonight in a stall instead of out in the pasture with the mares."

There was nothing else she could have said that would have made him capitulate, but his ears twitched up on his head in response to the word about the mares and he glanced at the chute again. He really didn't like the idea of getting into the thing, but at the same time, if getting into it meant that he would be able to end his day with the soothing presence of the mares, he could deal with it. That was why this was all happening, after all, and there was little harm in behaving himself, especially since he would be benefiting monetarily when he was changed back into a human. At least the shock had the added value of making his cock withdraw upwards towards his sheath again, some of his control reviving itself with his wariness on the thing in front of him.

He sighed and stepped forward, twitching his skin and keeping his ears well down as he was led into the chute. The metal was cold and kissed against either side of his body with a light touch that made him want to shudder and shy backwards. The animal instincts were controlled as he walked all the way in and felt the stone beneath his hooves before a lever was snapped down with a sudden crack. He squealed out, the sound erupting from his throat without thought when he felt the metal bars squeezing down to either side of his chest and sides, pinning him in place while he immediately kicked out behind him, the hobbles only jerked at the harness as his legs barely lifted backwards before they were stopped. His eyes rolled while the girl dragged his head down, pulling the lead through several of the bars so it was forcibly lowered.

"Easy, deep breaths. This next part is often quite uncomfortable, but it'll be over before you know it and you may even like it if you just calm yourself." She rubbed his ears, her hands smelled of his arousal, making him crinkle his nose up as she moved around the chute.

Alex's vision as entirely limited as he attempted to glance behind him, the lead tugging tight as she unwound a hose that was seated right against the barn. He kept his eyes on her as long as he could, but she was out of sight after just a few breaths and her hand moved to grip his club like tail and gave it a sudden pull to one side. Instinct made him try to snap his tail back into place, but her arm pinned it against her body and exposed the dark thick ring of his pucker as she did so. He kept his ears back, shifting and snorting unhappily, but he could barely shift as he was trapped in the chute, but he felt something trickle down right along his pucker. He immediately clamped up, tightening the sphincter in reaction as it trickled backwards and right down along his inner hind legs.

The girl didn't even tell him what she was doing as the viscous wetness was smeared all over him, squelching out from what sounded like some sort of container and it spilled right along the opening of his ring. It was cold enough to be a shock, his ears splaying and he strained to look back, but all he could see was her back and the curious end to the nose nozzle. It wasn't normal at all, not a tube like opening or even a sprayer, but a thick rubbery looking thing that he couldn't understand at all. He snorted and twitched his head a little, trying to follow it as it moved out of sight, but he lost sight of it as she drew it behind him and tightened her arm over his tail.

"Just try and relax, it'll make it go easier." She grunted as something nestled right up against his pucker and he let out an angry noise.

He clamped his muscles down tightly, affronted as the tip pushed right up against the opening and pressed forward so that he was left trying to keep it out as it continued to nestle forward against him. He'd never in his life had anything pressed against that part of his anatomy, it was startling and frightening to feel it nudging against his anal ring, and the girl didn't let him get an inch of give to stop the feel of it being stuffed forward. It spread him open, steadily forcing it's way forward and making his walls stretch ever so slightly before his contracting muscles kept it from being pushed forward. It was all together an unexpected sensation, embarrassing and infuriating as he tried to stop the blunt tip trying to nudge forward with a harder press, the girl leaning against it.

The sudden pressure began to dig harder against him, pushing the dimpled ring inwards as the opening was spread apart. He could feel the slippery stuff that had been poured on him helping despite his struggle to keep his muscles from giving into the slow penetration that was pressing against him. His haunches tensed, he tried to keep the thing out, but there was only a push that began to spread the walls open wider and wider, making his body twitch and shudder at the narrow tube that pushed its way into his body. It wasn't large enough to hurt, at least not really, it was just shocking to feel how his walls were stretching around it and struggling to hold the tube that was pushed deeper into his body, sliding through his untried walls. He clutched and squeezed down automatically, the clenching and pulling movements only aiding as the girl pushed forward with a bit more weight behind the device.

Alex grunted and jerked his head up, dragging his head against the lead, pulling back against the chute as several inches of the rubber was pushed into his straining body. He could feel his walls flexing and squeezing, the movements pulling along the length, trying to get a grip on it as best that he could so he could push it out. Not that he was given that chance, it was seated all the way up to a thicker portion of the base that sank into the opening, pushing the thick ring apart. The former man let out a short noise, the muscles tensing up along his back and towards the edge of his haunches he started to struggle to kick back. The muscles screaming at him to kick away the offending sensation, but whenever he lifted his hoof up he was stopped by the hobbles that were locked into place.

"Nearly there, just do your best to relax, it'll make the next part easier if you're cleaned out." The woman spoke up, grunting with the effort to keep pushing around the rubber tube, but it was a losing bottle.

As soon as the thickest point of the base was pushed up against him there was a sudden leap of the hose and a faint hissing sound as water bubbled through the tube and flushed out towards the rubber tip. He squealed, the sound startled and shocked as a splash of cold water erupted right into his bowels and began to pour through his body in a spill that rushed deeper and deeper into his body. It was chilly feeling, making his stomach want to cramp up as the thickness of the base worked to hold the stream inside of him and it had no where else to go but inside. He tried to lean forward, to pull himself away from the hose, but she only followed, leaning against his haunch to help to hold in him place as the torrent washed through him and began to make him feel as if he were weighed down it.

He felt as if his stomach should be sloshing about as it gurgled and the cold liquid twisted through him wildly, making his breath come in several short pants, his eyes rolling to show a rim of white as he tried to look back at her. The torrent didn't stop, it continued on, flushing through him until he stared to bear down around it, attempting to push it back out of his body as he did so. Some trickled out, he felt it slipping along his balls as his stomach grew heavier and swollen, as if it were rapidly inflating with the water flushing through his bowels and running through his inner body. He stomped and shuddered, trying his best to relieve the pressure, stomach twitching and cramping with a cold feel as he was filled full to bursting by the liquid.

The girl didn't give him a warning when she pulled back, the hose just tugged free with the base pulling free with a popping sound before the length of the tube pulled its way free and a sudden eruption of water spilled out of him. He jerked his head up in shock at the feel of it, the stream falling from his recently violated pucker splattered onto the ground and right along his hind legs as he naturally pushed and squeezed in an attempt to get it all out of him. The full and heavy feeling began to relax, but it with the humiliating splatter beneath his tail while he strained and pushed his pucker outwards, trying to move his hind legs further in to get away from the messy spill. His nostrils twitched and his nose flushed a hot red as the stream fell down to a simple trickle, leaving him wet bottomed and utterly humiliated.

Kimmy was far from done, the hose was brought up and suddenly sprayed him directly in the anus, he clenched the muscles down and let out a short shrill sound as the blast of cold air hit against him in a stream. He tried to avoid it, but the pressured stream washed roughly over him, moving back and forth this way and that so that he was left stand in place, helpless to get away. His ears dropped all the way back to his head, miserably feeling the wet trickle running along his hind legs, damping the thick feathering along his lower legs as he stood there and snorted, his breathing short and heavy.

"Sorry about that, lad, but I prefer to have a clean work space." She gave him a pat, her voice wasn't apologetic, but mildly amused.

_How dare she! That wasn't called for! _ He tried to put his anger in the way he glared back at the girl who wound the hose up neatly.

"Nearly ready, Kimmy?" Merrygold's voice brought his head up. "I've got the AV here and ready if you're about set."

_AV? _ He blinked strangely and shuddered his skin while the girl reached up and used a strap to wrap around his club-like tail.

"Yes, I'm just getting him set, he is less cooperative than I had hoped, but I got him into the chute alright." Kimmy answered as she used the strap to forcibly yank his tail out of the way, pulling it all the way to one side.

He struggled to drop it back down again, already feeling too exposed as it was and the situation wasn't improving at all as the girl snapped it down in place. He jerked his head back, staring this way and that, trying to figure out what they were going to do with him, but he wasn't given any hint as the doctor came and gave his back a light pat. They talked over his head, discussing something about how to adjust the chute so that they could open part of it. That suited Alex just fine, the moment they let him out he was going to give them both a piece of his mind. He was supposed to be given proper respect, he wasn't really a horse after all, but they were barely treating him with any dignity at all. She hadn't even told him what she was going to do and what she intended!

He tried to clench his pucker closed all the way as the girl came to his haunches again and reached up with something, he felt her fingers spreading around the edges and brushing something around his recently abused pucker. It was an absolutely frightening feeling to have fingers rubbing what felt like warm oil against him, the soft touch curling inwards so that the slight digit almost seamlessly slipped into his body. He contracted the muscles in a vain attempt to stop the offending digit from pushing forward, feeling the way that the interior walls were parted wider as the wetness trickled into him. It wasn't the torrent, at least, that the enema had been, but it was even more disconcerting as he stomped and tried to smack his fore hoof against the chute. It clattered uselessly off the metal as the girl kept working her finger around his cleaned anal ring.

"He is getting upset, isn't he?" The doctor sounded amused. "I'm sorry to mislead you, but you must understand that time is of the essence. Waiting for you to recover with each mating for the next could miss out on a mare in season, and right now we cannot afford that."

_I don't bloody care if you can't afford it! I didn't sign up for this. _ He let out an equine squeal of anger, his ears snapping down tight to his head.

"At least this way we can simply use several orgasms to impregnate as many mares as we need and as swiftly as we can, it will be awkward, but I'm sure you'll come to enjoy it. Most of the ones that have changed actually come to look forward to it." The doctor continued without seeming to care about his feelings.

He felt the girl sliding her thumb just inside of the anal ring and curled into the flesh lightly, pulling it with a gentle drag that made him grunt out and clench down harder to prevent her from prying him too far open. It felt invasive the way that she pushed the walls open and spread him so that something could be slipped up against the taut ring. At first, it was very much like the rubber tube had been, quite small and slight, barely anything that he would have thought of as invasive or worrisome, simply humiliating, but the first inch that slipped into him changed radically into something that flared open wide like a cone and came up hard against his opening and tried to force its way through his aching muscles. He clenched down harder, squeezing as much as he could, but the pressure only grew as the girl leaned forward against the base of the toy and started to spread him open.

Kimmy didn't get very far, Alex's muscles held firm as he was barely spread and he tightened ever muscle he possessed to keep himself from being impaled. She was pushing harder, the oil did help, it was sliding around the device, but it didn't really do much to stop his contracting muscles which gave him some purchase to keep himself from feeling it slamming home. The more she pushed, the more he bore down, his ears slicked flat to his head as he tried his best to keep himself from giving into the steady press of her hand against whatever it was she was trying to stuff inside of him. The few centimeters she did manage to push in were bad enough, his muscles splaying open around the thing, caressing down and squeezing as it set itself deeper and deeper.

It might have gone on far longer if it hadn't been for the doctor, certainly he had no intention of letting her do what she was trying to do, but the chute rattled as a small panel was dragged back along the wall to reveal his legs. It wasn't that movement in particular that startled him, but the sudden feel of a hand reaching beneath his stomach and up towards his sheath in very much the same way the girl had been doing only a short while ago. The man's hands grabbed at his sheath and Alex startled, his attention diverting for a single moment, but a moment was all it took for another slow few inches to sink their way into his body. The torturous feel of the sleek device splaying him sent a spasm of pain through him while he felt the thick rod sliding deeper into his body, pushing his walls apart.

He belatedly clamped down with a low noise of shock, but he felt himself splayed open wide with several inches of the thing driven under his tail. He couldn't evade them as the girl kept pushing forward, working the lube through him in a way that far outdid the way her fingers had danced over him. He shuddered and jerked his head, tugging against the lead, feeling another stab of discomfort as his untried muscles twitched and quivered, the ache building through him as he jerked his head down and back up again. Another steady push sank the thing through him, gliding along the insides of his passage, rubbing deeper, another thick inch stretching him open even further. It was shaped very like a cone, the thickness seeming to come from a never ending source. The girl didn't try to make it happen all at once, she kept it a slow steady progression that had his sides heaving in short breaths, eyes squeezed shut in silent humiliation. They knew he wasn't an animal, but they still violated him!

The hand on his sheath was harder than hers had been, firm and reaching as the fingers pushed their way directly into his sheath and began to draw it outwards, tugging against the wrinkled flesh forcefully. It was a distraction, one that he dared not pay too close attention to as any time he did the girl was able to sink more of the device under his tail. He felt as if he were split in two, wide open and vulnerable to the world as a thick ridge of the plug pushed his anal ring inwards as she worked the toy back and forth. After a moment, it twisted and turned, screwing itself inwards as his tightening muscles briefly held it at bay, squeezing a small bit out of his body again, but the girl quickly reclaimed it with a press forward again, the ridge once more grinding against the thick outer edge.

He let out a ragged noise, body shuddering in a brief feeling of frustrated helplessness as she pushed the thing inwards, sliding the ridge past the taut barrier of his sphincter and laying claim to the inside passage. He grasped around it, distressed to realize he could feel the entire shape plainly, every inch of it while the flesh of his cock was dragged free. He felt the hands holding him, the possessive grip tugging his cock down lower whether he wanted to or not. He tried to stomp one fore hoof back, but when he did he felt a sudden jolt as the ridge pushed up and over a particular spot inside of him. It wasn't a jolt of pain, but of queer pleasure that made his muscles contract powerfully as the girl panted behind him.

"You could at least try and relax." She chided, making him squeal furiously back at her, the hell if he would cooperate with this violation!

The thing's base slipped in, the final ache of thickness driving itself home before his anal ring was able to close down. The thing became far smaller behind the obscenely thick ending, making it form a heavy plug driven into him, his hind legs wanting to naturally splay from the discomfort as his sides heaved up and down. He would have rather mucked the stalls out with his hands than do this, it was all wrong, his lovely dreams of mares raising their tails were gone as the man under him stuffed the tip of his cock into some sort of soft feeling pouch. It didn't even feel that good, it was just another humiliation heaped onto the entire experience.

"Start him out slow, he's not even partially hard, not that that is surprising. They never are at this stage." The doctor spoke up, making Alex lift his ears at the words 'they never are'. How many men had they done this too?!

His questions couldn't be answered, even if he had had a mouth they wouldn't have come out, not when there was a sudden pulse that rippled through his violated body. It wasn't much, a little spark and sense of vibration trailing over him and throbbing through a particular spot that brought his head jerking up against the leads. It made his muscles leap and quiver strangely, making part of his body twitch and swell, his cock pushing out against the hand that pushed him deeper into the sleeve that was being drawn up along his cock. It wasn't unpleasant feeling, but it certainly wasn't something he wanted to feel as it pushed up higher on his shaft and towards his sheath. He shivered his haunches, trying to push the plug out of his body, but as his walls shifted around it, the thing vibrated again.

This time it was a bit stronger, a sudden jolt of electricity that shot through him and rippled right along the line of prostate, making his cock flex and fill out in an uncontrolled flexing. His ears twitched flat to his head and trembled a little bit as the sudden reaction to the electricity took him off his game, he shifted and stomped a hoof, throwing his head down and jerking it back up again as he tried to figure out what it was they were doing. He was humiliated and violated, his entire body impaled and stretched open on the strange thing that was seated inside of him, trying to ignore the feel of it shifting as the girl turned it inside of him, a slow twist and rub along his prostate before another jolt hit him.

He squealed out and went tense, this jolt was harder, a snap of electricity that made his cock stiffen up and swing up inside of the sleeve, suddenly hardening of its own volition. He couldn't control it! It wasn't in response to his own arousal, it was in response to the jolts of electricity making his body twitch and flex, the muscles contracting to stiffen the flesh as another pulse ran through his body with a sudden spasm that jerked through him. He kicked back, his hind hooves trying to strike back at the girl, but it only drew the straps tight as he felt another ripple of electricity strike through him, a brief stab that made him feel painfully hard within the sleeve, his eyes showing white around the edges in fear and anger, nostrils flaring wide to suck in a breath and let it free again.

"Just relax into it, just enjoy it.." Kimmy was saying, her words an attempt to make him listen, but he was worked up and frightened as his control of his body was robbed by the toy pressed beneath his tail.

Another stroke, he could almost taste the electricity as he squealed out and his hips jabbed forward immediately, his cock flaring and spreading within the tube. It was soft feeling, rubbery, as it wrapped around his hardened flesh, but the feel of it mattered little to his body as he began to shudder. It was almost painful feeling as it struck him again and his entire hind end felt locked in a moment of tension and twitching muscles, his tail uselessly trying to flag up behind him before he felt another stab hitting him, this time harder. It made his back and sides shudder in place as his cock jerked and twitched within the tube that hugged around it, the tip trying to spread open wider, the pressure increasing as it clutched about him tightly.

He could almost time the pulses, they were short and swift, just enough to take his breath away, but not enough to do more than add to the torment of his tensed muscles. There was no escaping them as he stomped his hooves about, rattling the chute loudly as he made every attempt he could to get away. Not that there was any where he could go, the girl refused to give him any sort of relief as there was another jolt that ran from the plug and into his vulnerable anal passage. It struck him hard, making every go stiff and hard, his entire body locked in place as it pushed through his loins and his cock swung up high and his balls contracted. It was almost painful, the sheer pressure of the act drew a squeal past his lips, one he couldn't stop even if he had tried as his orbs began to work.

It wasn't the rush of pure desire and pleasure, relief at orgasming, that filled his mind, but an ache of overly tense muscles as the cock tip erupted out into the sleeve that covered him. He felt the hot thick stream of cum spilling from him, the eruption flowing out and into the channel in a hot heavy rush, flinging outwards in a heavy rush, pushed upwards by his twitching and contracting balls. Rope after rope flooded out, running into the passage, he could feel it, but it didn't stem down after the first few spurts, it continued as the electricity ripped through his body, locking him in place through the stream of sperm rich cum puddled around the tip of his cock. He rattled the chute, shifting it and jerking back and forth, humping forward with his eyes squeezing shut.

It went beyond pleasure within a simple breath, it ached and was painful, a raw feeling as his stiff cock humped into the sleeve and he was helplessly flooding it, emptying it out before the last dribble oozed out of his tip. His sides were rising and falling wildly, panting shallowly, his eyes remaining shut as the sleeve was dragged from his drooping cock. The wet mess of his seed was still clinging around his tip and slipped free with a wet splatter before falling uselessly beneath his belly, he couldn't even feel humiliated by that, his ears twitched tightly to his head. His sides were heaving, rising and falling, ears splayed to either side while the girl grabbed the base of the plug and began to pull.

He groaned out, his walls twitching and quivering slightly, squeezing as the thickness of the base pulled from him with a slow smooth movement, making his anal ring feel a moment of aching pressure before it slipped all the way out of his body with a wet noise. He let out a short noise, eyes closing tightly under the assault of feeling his body having the thing dragged from him, the lubrication helping slide it free. He lifted his head and let out a noise, the equine sound spilling free from his muzzle, angry and humiliated as the plug pulled all the way out with a pop and left his abused pucker straining to close itself again. He had never been treated so badly in his life, it went entirely against his contract! It had to be illegal, at least somehow.

"You might as well bring out Darius, it's easier to get the whole thing over at once." Merrygood commented as the man stood up, cupping a filled sac at the end of the AV, far more cum than Alex would have thought it possible to produce.

_Darius?! Let me go! _He kicked roughly and twisted, trying to get his way free, but he only managed to bruise his sides and shoulders.

"Poor new guy, don't worry, it'll only be until we sign on a new stallion." Kelly put away the plug as she spoke, sounding almost sympathetic. "But we can't really well give these fellows a new body and not expect them to want to try it out."

_Try it out?! _ He snapped his head up, swinging ot either side, jerking back and forth as she returned to him.

"It'll be a lot easier since we just used the plug, you're already stretched out, Darius has been new guy since you, so it'll be good to let him have a go at being the one doing the mounting." She sounded so cheerful as he realized just what they were talking about.

They were going to let a stallion mount him as if he were a mare! He bucked, hurting himself against the bars as he felt his spent cock swinging back and forth along the line of his belly, messily coating some cum against his hind legs as it smeared against him. The chute barely rattled in reaction to his struggles, instead it rubbed fur off his sides and along his chest, rubbing back and forth as his hind legs snapped to either side, yanking at the hobbles. Kimmy didn't even try to make him be still, instead, she reached up and began to unsnap a portion of the walls along his haunches, swinging them open so that he felt a brush of cool air against himself. She was going to let him out!

He tried to leap backwards with a kick that yanked at the harness and hobbles, but just his haunches were left out from the chute and he was able to high step and storm about this way and that, but his forebody was still locked firmly in the grates. His attempts to get free only formed more bruises along his shoulders, but he could at least swing his haunches about somewhat. He felt the wet fur being chilled in the air as she stepped away, leaving the two sides folded well down so that his haunches were entirely bared to anyone who so much as glanced at him. Not that he had to wait long to have someone staring at him, a beast of a horse stepping out of a small barn just down the road, and not a mare.

_No.. NO NO NO NO!!!! _ He squealed to himself, frightened and horrified to see a large shire being let out.

He was larger in every way, with a glossy black coat in frothy white feathering along his legs as the beast began to pick up his large plate sized hooves and stamped up and down. Heavy-bodied, the animal was massive looking as the powerful large legs shifted and moved naturally as the massive head was lifted up and dark brown eyes were glittering eagerly. It wasn't the size of the body that was terrifying for Alex, it was the fact that as the stallion walked towards him something was drooping down along the underside of the belly. He jerked and bucked, trying to kick his way free as he saw the pink and black fleshed cock spilling out, terrifyingly large and swelling rapidly, filling out and bobbing back and forth with rapid little flexes upwards as the beast snorted and snuffed at the air. His ears were both up high, eager looking and bright eyed.

"Be gentle with him, now. You remember what it's like being the newest." Kelly commented as the overly large beast came stomping up to the chute and began to chuff out at him hotly, the nostrils spreading open wide and blasting a rush of heat out against him.

He flinched as the beast was close enough that he could see the swell of muscles along the powerful sides. The other stallion was taller than he was by at least two hands, the body just as stocky, but larger in every way as the nose shoved against his haunch and let out another blast of heat against him. He attempted to swing to the other side, side stepping and shuddering, his wrapped tail slapped back and forth, but he couldn't move nearly at all as the chute and hobbled forced him to submit to the way that the nose was stuffing and nosing at him, jabbing roughly at times so he felt bruising grips right at the base of his tail as the monstrous cock began to swing upwards beneath the line of the stomach, slapping upwards with a loud sound.

It was larger than Alex's, thicker and heavier looking as the stallion swung around with a shrill whistling whicker of eagerness, not at all caring that his prospective 'mare' was trying to get away. He was pushed about, the nose stuffing above his haunches. The other stallion was a changed human, he should have known that the man beneath this body wanted nothing to do with what was happening to him! He should have stopped, something... anything, but instead, the shire swung all the way behind him and crashed his chest right up against Alex's haunches. He let out a shrill wild sound, shaking his head back and forth, trying to show that he wanted nothing to do with this! He was supposed to be the one doing the mounting, he was supposed to have been given a mare, he was supposed to have-

His thoughts were stopped as the chest suddenly rammed up against him and the two forelegs suddenly hooked up against him. The weight of the draft stallion pushed him down, making him shudder and shift, clattering his hooves roughly against the ground as his hind legs were splayed open as the muscular feathered legs were hooked to either side of his body and the hard edges scraped against him. The large chest pushed over him, the heavy head pushed higher up before a set of blunt teeth suddenly snapped out against the ridge of his neck and pinched down with bruising force as the cock swung up and slapped right up against his haunches, splattering out a rush of thick precum, coating against him in a wave as he tried to leap upwards, attempting to get from under the grip of the other stallion.

The teeth clenched harder as the changed man grunted on his back, the noises wild sounding as the swollen obscenely large shaft began to jab right up against his haunches with short wild movements. The wetness dribbled out of his tip, he felt the syrupy precum drooling down right along the back of his balls as he swung his head wildly to one side, squealing out again. This wasn't how this was supposed to happen! He shouldn't be feeling the warm heavy weight pressing against him, pinning him in place, refusing to give him any escape as the legs hooked tighter against his haunches before the swollen tip jabbed up towards his recently violated pucker.

He tried to clench the muscles closed, tensing up, his sides heaving slightly as the cock tip caught right against the taut ring and shoved right up against the opening with a rough grunt and jerk of the muscular hips. He couldn't stop it, his body was still freshly lubricated, his inner passage began to be pried open, the walls forced to spread along the cock tip that sank it's way forward with another rough lunge. He cried out, eyes watering as the sheer size of the blunt tip pushed home and slid inside of him several inches, the mottled flesh bowing under the pressure as he heard the animal above him letting out a triumphant noise. Alex's walls clutched about the girth, flexing and quivering, squeezing to make it harder before the stallion pushed his way home deeper, shoving its way through the inner muscles.

He couldn't get away from it, his entire passage felt as if it were being torn open as the thick slab of flesh sawed its way in deeper, the precum oozing out messily to spill inside of his passage and being flung in deep before squelching out around the edges. The forelegs scraped against him, jerking before the shire hunched forward with another thrust, driving another few inches back into his body and spreading him open. Unlike the plug, there was no careful ease of a small tip, the entire spire was designed to be thick and heavy as it slid ever deeper, pushing its way past the thick ridge of flesh, forcing his anal ring in on itself. Every twitch and contraction tried to hold the stallion out of him, attempted to prevent it from gaining any more ground, but it was a losing battle.

Another thrust and he felt a thick ridge of flesh pushing against his pucker as the hips swung forward, the chute was digging along Alex's chest as he squealed out helplessly. His entire body shuddering in reaction as the medial ring was pushed past the opening with a wet popping sound, precum being edged out by the sheer size of the stallion's cock. It slid home, Darius drove himself with a powerful buck that suddenly forced the thickest point of the base into his body and then pulled back again, the movement grinding the flesh through his body as he shook in place. He was squeezing around it, helpless to stop the movements, he was suckling and pulling along the inches, drawing them in deeper.

The blunt tip worked to smear precum all the way through his passage, the slow smooth movements designed to seat the tip as far as it could possibly go inside of him. Alex's entire body was locked up, struggling to accept the equine flesh that teased through him, the warmth of the precum rushed downwards in a wet splatter even as more of it was flung into his depths. He felt wet and slippery, his own body quivering and twitching, holding around the cock and squeezing so that the stallion had to use his full weight to drive himself home. The other stallion's wet saliva coated along the line of his neck as the teeth shifted their hold, moving further down along his neck to capture the skin along his shoulders.

He had no escape from it, he twisted and squealed out again, letting out a short noise before being rocked forward once more. The ache of having the flesh pushing through him offset by the horrible sensitive left behind by the electricity. Every time the medial ring scrubbed it's way over the line of his prostate he felt an unwilling flinch of pleasure, humiliating in the extreme as he reacted to it, he didn't want to react to it! He didn't want to enjoy any part of this torment, he had imagined himself on a mare that would squeal and buck, not become such a mare himself. He twisted, his hind hooves splaying wider as the next thrust seated the cock tip oh so deep into his body.

The blunt tip began to pray him open wider, packing his bowels with thick horse flesh that was straining to pry every inch of his passage open wide. He could no more evade it than he could free himself from the restraints, he was forced to feel as it flared open wide, prying his inner walls open and struggling past his contracting muscles. He dropped his head down, his ears slicked far back upon his head as the hips gave another series of jerks forward, working harder, faster, the speed building up rapidly as he squealed out again. The sound burst free wildly, his eyes flashing as a set of heavy balls suddenly crashed up against his own, heaving upwards with a heft that made him kick back at absolutely nothing, the movement sending a shudder past his haunches before the shire leaned over him, more weight holding him pinned down in place.

The first throb ran up along the passage, he felt it, quivering and twitching before a sudden hot gush of seed erupted from the cock tip and poured through his bowels, flooding him for the second time that day. He tensed up, his haunches shuddering, the muscles tensing and relaxing as the ropes were pushed through him and the stallion rested heavily along his back, pinning him in place. The hot streamers coated his inner body, hot and heavy feeling as his walls seized up and massaged along them, pulling slowly, dragging towards the tip. He couldn't stop them, they had a mind of their own as his sides rose and fell rapidly, ears swinging flat back upon his head. He was humiliated, used and messy feeling, the stallion on his back kept clutching against his haunches, shifting the weight back and forth lightly as the hot breath ran right along the line of his neck. He flinched away, making him twitch his skin as the teeth finally released him and he felt the last surging spill of cum drool outwards as the cock began to rapidly soften. The head lifted, a hot snuffling breath kissed his ears and forced him to lower his head further, desperately attempting to evade the attention from the large male. He couldn't believe what had been done to him. He hadn't signed up for this! Not at all!

"Don't worry, Alex." Kimmy spoke up with sympathy in her voice. "They all find it hard to get used to when they're the low stallion on the pole, but when we get a new one you'll find out how enjoyable it really is."

_ I don't want to find out how enjoyable it is!_He twitched and shuddered as the cock slipped free with a wet slurping noise, a splatter of cum fell downwards along the back of his legs, coating them all the way to the hooves.

"Until then, just think of it this way, at least all the seed we get from you will be used to father the first generation of Gypsy Vanners. You'll soon be a father!" She rubbed his shoulder lightly as the large stallion slipped off his back, his aching pucker drooling a wet splatter of cum down behind his sore balls.

_ It wasn't supposed to be like this.._
