Fad bioengineering was all the rage those days. The product of a myriad of joint advances in genetics and biology that allowed for a wide array of physical changes that ranged from the daring, to the subtle, to the markedly grandiose. One popular way to experience this popular new frontier was to go through a ‘genetic revision and transfiguration adventure’. With the many possibilities this opened up, a small but passionate group frequented the few businesses that catered to adventurers looking to see what it was like to be an animal. Every so often the group gained a new member or two.

Sat in the nondescript waiting room of a building at the edge of the industrial district were four people. A man and woman, a couple, another nervous younger man, and a lone woman. Everyone was on their cell phones, the couple sitting next together with the lone woman opposite them and the nervous man on the other side of the room. The walls were a drab beige, and there were no paintings or potted plants but end tables with magazine and literature from the clinic on their many adventure packages. The only door was the one they came through. It led, after some twists and turns, to the street.

Out of anything to look at on his phone that would calm him, the nervous man swapped it for one of the clinic information packets. He was barely out of college, thin, shaggy brown hair, pale skin, glasses, and had on sneakers, jeans, and a hoodie to hide himself. It was his first time here and it showed. The lone woman was scarlet haired, darker skinned, taller, with curves the nervous man could appreciate in her skirt and tight top. The way she sat casually, legs crossed, with a relaxed smile told him she had been here a few times before.

A similar air was about the couple who whispered and joked back and forth in whispers. They were in their mid-thirties, married based on their matching wedding bands, and could have had kids by how normal they looked. The man was on the fatter side, average height, trimmed beard, nice watch, jacket, slacks, and boat shoes. His wife was pretty, short, thin, with the exception of her chest, blonde hair, rosy cheeks, blue eyes, and wore a black dress covered in dark green roses. In the chair next to her was her folded jacket under her purse as she hadn’t come in off the street wearing such a thing. They could be relaxed in here but out there this sort of thing still earned you uncomfortable stares from strangers.

The nervous man, real name Dennis, knew why everyone was there. The same reason he was. To be an animal for a few hours. Beyond that he wasn’t sure if they were going for one of the other packages in the literature he was offhandedly flipping through or were going to one of the ones involved in his pre-paid adventure as a horse. Part of his package was interaction with other clients so one or all of them could be involved in his first time trying this sort of thing. He’d read about it online and watched plenty of videos but sitting there knowing everyone in the room was there to indulge the fantasy of being a barnyard animal. It was this clinic's speciality afterall.

Dennis himself was excited for what was to come but was nervous for the many unknowns too. He’d never messed around with much genetic manipulation since he hadn’t had the money. This being his first time he had built it all up in his head with very high expectations of what to get out of it. The transformation and time as a horse, a stallion, was part of it; there was also the freedom to gallop and the new experience of the body itself. Underneath he relished the thought of sex and mounting most of all but wouldn’t say as much but the salesperson who set the adventure up. There was a chance one or both of the ladies in the room would get to know him on a personal level and so he stole glances of them where he could.

Getting just past five minutes past Dennis’s appointment time the door opened and in walked a woman in a tight gray jumpsuit with a digital pad in her hands. Her copper-red hair was tied back, tan skin, elegant figure and face, glasses, and she had ID tags, lanyards, radio on her belt, and other equipment that marked her as an employee.

“Good morning everyone. I’m tech Janelle. I see four faces here that match what I have here on my list. Some of you are familiar faces too. You’ll know that I have to go through the same introduction as always since some are here for the first time. We’ll head down to get things started but first I want to get everyone’s monikers out of the way as per usual,” began the tech in a bright, disarming voice.

“We’re happy with our usual ones,” the man told Janelle as he squeezed his smiling wife’s thigh.

“I assumed you two would. You’re Ginger and Shadow then. As for you,” Janelle paused to look at the lone woman.

“I wouldn’t mind something different this time. The last one didn’t really suit me,” the lone woman remarked in a quavering voice.

“That’s unfortunate, Miss, but not a problem. Let me just generate one for one… How does Nelly sound?” asked the tech.

The woman thought about it, silently saying the name a few times to try it out. “Sure, I’m fine with Nelly,” she smiled.

“Wonderful. Now as for you,” Janelle turned to Dennis who couldn’t stop a tremor of anxiety passed over him as all eyes on the room fell on him. “What do you like more, Ryder or Blackjack?”

“Uhhhhh,” Dennis sputtered. “I’m good with Ryder. Yeah, I like it.”

“Nice to meet you, Ryder. We here at The Farmstead Clinic welcome you, Nelly, Ginger, and Shadow to today’s ‘Horseplay at the Ranch’ adventure. Privacy is kind here so please only use moniker when talking to fellow guests. If you’ll follow me I’ll show you to our Shifting Room to truly get into character,” Janelle warmly greeted everyone while motioning for them to follow her out the door and into the hall.

Everyone gathered their things, the couple leaving first and Nelly leaving next as Ryder, formerly Dennis, held the door for her. He got a smile for his efforts and was a little less nervous as he brought up the rear.

The path had different twists and turns than the one that brought them to the waiting room but it felt very similar with the hallways all the same color. Eventually they came to an elevator that took them down four levels. The hallway they walked into from the elevator was wider, less spotless, more grime, wires and pipes were bundled together on the walls, hung from the ceiling, and snaked under the grated metal floor. There were also bales of hale next to padded crates and larger powercells with their casings cracked open- meaning they were bought secondhand. There were a few doors on the sides with each requiring keypad multi factor authentication.

Ryder’s nerves stayed frayed as they walked down the hallway and he saw the slightly haphazard setup. There was nothing illegal about doing these adventures and the clinic had all the right certifications and licenses. That didn’t stop engineers, techs, or maintenance here jerryrigging something and no one else minding it. It would have had him more on edge had the others, the repeat customers, not been so calm with what was clearly not unusual to them. They were paying attention to Janelle, like Ryder reminded himself he should be.

“We ask that you listen to all staff requests and to not argue with anything they might ask of you. If you have questions you can direct them towards me who will be supervising your adventure today. Once you’re in your harnesses, the other techs will have limited to no verbal interaction with any of you so to not overly distract. Really they’re needed most at the beginning and start so try to imagine they’re not there for the most part,” Janelle pleasantly explained as she led the way. “You have all been put together as your requests overlap rather perfectly. Feel free to talk to each other using your monikers once we’ve completed stage two. We’ll remind you again when the time comes. Until then, remain quiet, listen carefully to all staff instructions, and follow them.”

“Looks like good company to me,” commented the husband as he glanced around at the others.

“Great company,” agreed the wife. She flashed a wink to Ryder, making the man flush in the cheeks.

“What’s the mix of sticks to licked for this one?” inquired Nelly. The woman had taken on a swagger since they exited the elevator that Ryder was loving. She was passing looks in every which way. Ryder’s included. Likely enjoying him being lost to the lingo.

“They’ll be one to three for this adventure. Not a usual combination for us but we expect some very good results all the same,” promised Janelle. They were headed for a heavy set of piecemeal metal security doors with hefty locks. “Once we are through the doors everyone will follow me to the left where we have an area for you to undress, store your belongings, and finish out stage one prep. Is everyone here excited for their big adventure today?” she asked excitedly.

“So ready,” agreed the wife while her husband nodded in agreement.

“I’ve been raring to go all week. Can’t wait to get settled in,” Nelly swooned as she bit her lower lip.

“Y-Yeah,” Ryder said in a cracking voice.

“Wonderful! We’ll be going through these doors ahead and into our Shifting room. This is where your physical transformations will take place. This is also where you’ll come when you’re changing back to your human state. So this is something of the gateway to your equine adventure today!” They reached the doors where Janelle had to enter a passcode, pass a finger and retinal scan, and provide a verbal verification before the doors would open. All while under surveillance of four cameras. “Please do not touch anything you might see there unless told to. My other techs should have everything all but set up for us. Follow instructions and this will all go by before you know it.”

When the doors at last unlocked and pulled apart they dove into the sights, sounds, and smells of the large, busy room. The ceiling was fifteen feet high and the walls were far apart and hard to determine thanks to so much unused equipment being stored at the side. It was definitely impressively large to Ryder while also having an intimidation factor. There were all kinds of pipes and wires in the room with many hanging from the ceiling where they hung freely or were plugged into rigging. There were four rigging stations from which were suspended straps and automated pulleys. One for each of the clients, including Ryder.

The thought had him excited just as the ten techs rushing around getting everything ready did. There was an air of anticipation about which Ryder found fueling his anxiety and his enthusiasm. As the group took a hard left towards a small walled off area with lockers and additional cubicles. The other customers were chatting with Janelle while the newcomer ogled the mix of sleek, expensive gear and utilitarian simple modifications. He’d seen similar setups in his research but never this exact one. That was making it extra exciting for him.

Entering the changing area the three returning guests were quick to separate to their usual spots while Ryder had to wait for Janelle to say something. “Find a spot with a locker, get full undresses, don’t be shy, and put everything into the locker. One locker per person, please. Scan your thumbprint on the lock and it will remember it for when you turn back. Be sure to remove any pieces of jewelry, watches, necklaces, charms, haribands, bobby pins, or any other objects from your body. I’ll have four techs in momentarily to go through a final checklist so answer their questions truthfully and to the best of your ability. We’ll get through all this in a snap and get you all suspended before you can shake a horse’s tail.”

Ryder took the hint and found a locker near where Nelly was. She was undressing at a brisk pace while the newcomer fumbled to open the locker and then again when taking out the things from his pockets. The others got undressed quickly which prompted Ryder to do the same. He tried not to overthink it too much as he took off his own clothes, keeping his eyes forward. Once he was naked he took his time closing and locking everything. Partially for nerves, partially for his smaller than average manhood, and to try and hide all this on his face when he turned.

“Hello Ryder, I’m Courtney,” asked a blonde tech that had been standing right behind the man waiting. Being on the edge as he was, Ryder jumped back when he saw the neutral faced tech with a digital pad. Nelly, her tech, and the couple all giggled at the newcomer while he gathered himself. “I’ll be administering your pre-shift paperwork. I need to confirm some information with you and run some medical checks. If you can give me your finger and answer all my questions we’ll fly through this,” Courtney assured as she clipped a device for vitals on Ryder’s finger.

The questions were mostly confirming information Ryder had provided ahead of time making it easy to nod and look around the room. Mostly at his fellow contestants who he could see in the buff. Both women looked very nice nude with Nelly being trans and a good bit more endowed than Ryder himself. Ryder noticed tattoos on the couple- ‘Shadow’ written in cursive on her lower back and ‘Ginger’ in orange lettering in the middle part of his upper back, just below the neckline- that settled who was who. Ever aware of it he saw the husband was very well endowed. Making Ryder wonder whether he or Ginger would have the bigger stallion junk when fully transformed.

“Ryder? Hello? Did you hear me?” Courtney curtly asked the distracted newcomer who had missed her question.

“Sorry, what did you ask?”

“I asked if you’ve had anything to eat in the last twenty-four hours or if you abstained as requested?” Courtney repeated herself. Clearly annoyed to do so.

“Oh, no, I haven’t eaten anything in the last day,” he lied to her on the spot. As soon as he realized what she was asking he remembered that he wasn’t supposed to eat anything for a day beforehand and nothing to drink for twelve hours before the appointment. Ryder had done both, having quite the large meal the previous night. But he didn’t want to risk losing his spot so he risked lying about it and hoping it wouldn’t be an issue. He didn’t feel like he had to go anyway.

“Excellent. And you haven’t had any liquids in the last twelve hours?”

“No,” Ryder lied again.

“Did you take a bowel cleanser as requested too?”

“Oh, yeah… yes. Did that yesterday evening.” He committed to the lie and was trying not to sweat it.

Courtney checked the boxes on her side. “Good. You might experience some leakage of fluids like urine and semen during the process. This is normal and as long as you’re not packing a full bladder it won’t be too messy. Next, have you exhibited any symptoms of cold, fever, chills, hot or cold flashes, or any strange physical symptoms?”

“No. I’ve been in good health,” Ryder answered.

“Your vitals appear to agree. Please follow me over here so I can take your height, weight, and a small blood sample,” invited the tech who was looking to hurry things up.

The tech walked the newcomer over, asking more questions about Ryder’s general health. She then took her measurements, a sample of blood, as well as a saliva swab. There are several more questions from Courtney while two techs make quick measurements of Ryder’s chest, arms, back, arm, and legs. These two techs then hurried over to the cradles to make the appropriate adjustments to Ryder’s waiting suspension unit. By the time Courtney was done with all her questions and tests the rest of the group was waiting on him to progress.

“Now that we have everyone here we’re about ready to continue,” Janelle began as she smiled at Ryder’s approach. “You’re about to be led to your individualized cradles where you’ll have your regene-therapy and subsequent physical transformations. You’ll be suspended in a unit designed to adapt to your shifting growth to keep you as comfortable as possible throughout the experience. There will be a clear ointment applied to your whole body just before entering, which should be at least room temperature by now, that will assist in the transition process. Should take between forty and forty-six minutes for everyone to finish. Changes propagate in much the same sequence for every client but variations in requests result in uneven finish times. Rest assured by the time you’re all moving to stage seven you’ll be reunited for some fun together. Please, follow your attendant to your cradle.”

They walked out two by two behind Janelle with Courtney again doubling with Ryder. Ahead were four stations set up ten feet apart from each other in a line with two techs waiting on each; one had a high pressure sprayer and the other several large syringes. With cold floor underfoot the four clients moved gingerly to their individual cradles. Ryder was brought to the second station from the left with Nelly and Shadow either side of him taking everything in stride. Ginger was on the other side of his wife to the right and was showing his experience as well in assuming the required positions.

“Arms up over your head, please,” the tech with the sprayer ordered Ryder.

He nodded and raised his arms whereupon the tech set about spraying him top to bottom with something that looked like hot petroleum jelly and stuck to his skin like glue. The other tech spared no time either administering a total of four injections.

“Apin. Readying agent. Stabilizer. Intializer,” the tech said with every poke of a needle.

Courtney had got to work getting the cradle ready so that when Riley was fully coated and woozy from the series of injections. All three helped him step his legs into the lower part of the harness and then strapped his arms in along with two more straps across his chest and stomach. His head was fitted to tilt his head up slightly with a strap pulling back gently against his forehead. This wasn’t terribly comfortable until he was swung forward and let to hang freely. This left his arms, legs, and genitals hanging under him while the rest of him was well supported and his head was well positioned.

While the techs worked in concert to attach hoses, adjust straps, fix tolerances, and stick on several sensors for monitoring Ryder looked left and right to see the others all smiles and calm. Nelly was bobbing her head to a tune and the couple shared knowing looks with each other. Seeing them all waiting it out told Ryder that’s what he should probably do so he tried to calm himself down. The pain meds and possibly the skin gel made his flesh feel numb, warm, and tingly in a way that was close to pleasant. It made the tug of the ropes and their rub against his skin disappear so Ryder was floating on a cloud.

After ten minutes of frantic work that included checking and rechecking everything the three techs at Ryder’s station joined the other three, who had already finished, in reporting client readiness for stage two. Janelle was standing behind a central monitoring station surrounded by screens on a raised desk.

“I’m showing all green flags across all four cradles. Great work, team. Let’s get these four folks off on their journey. All crews are authorized to access their catalyst masks. We’re onto stage two and making great time!” Janelle touted pridefully.

Much of the process so far had varied from what Ryder had seen in videos and pictures leading up to coming to this particular clinic. He enjoyed that it was so different. The catalyst mask was the exception to the rule as it was brought in just as he’d seen many times before. Housed in a metal glass mini refrigeration unit and requiring two techs to hold and operate, the mask emerged from mist that billowed out of the open door. It was made of black metal with numerous plastic and rubber parts that were made to fit over the nose and mouth. Attached to it was a gallon sized glass cylinder filled with a dense, slowly churning tan smoke. The glass frosts over as it's brought up right in front of Ryder and affixed to his face.

“I want you to exhale fully and then take the deepest breath you possibly can, Ryder,” Courtney, one of the tech’s holding the mask, told Ryder.

Ryder exhaled to his limit, his heart racing despite his efforts to calm it. He knew this was really it. When he couldn’t stall any longer he inhaled deeply as directed. There was a sound of pistons letting out air as his breath rapidly drew in the smoke through the mask and into Ryder. It tasted of dry oats and sandpaper while having the effect of coating his mouth, throat, and lungs in a similar fuzziness to his skin. It was all over in six seconds and after the mask was removed, just like Ryder had heard, the expected urge to cough wasn’t there. The smoke had melted into him and breathed out cleanly. Not even a puff of the smoke escaped.

While Ryder and the others clients dealt with an aftertaste of shoe leather the techs put away their respective masks and made preparations to leave. Two techs would gather equipment onto a cart while the third made a final check of vitals and of all the hardware.

“Congratulations, folks! You are now truly on your way to your ‘Horseplay at the Ranch’ adventure!” announced Janelle to workers and clients alike. This while her attention was on the many screens around her. “I’m showing green across the board and verified signs of regene sequencing success. Attendants sound off when you sight visual shift of the dock point and I’ll confirm us for stage three.”

Courtney and other lead attendants were positioned behind their guest with eyes fixed on their backside. Meanwhile one of the other techs at each station rolled their equipment away while the other techs brought down suite’s of four flat screen televisions that were nest up in the ceiling in front of every client. Two screens were in the middle with the top showing him from the front and the rear camera showing his rear. The two side screens were angled shots of either side of him. Giving Ryder and every client there a full view of themselves. Which included the attendant leaning over their rumps.

As Ryder hung in his cradle he could feel his body awash with varied sensations. Tingling heat and painless needles covered every inch of skin. Gasses shift and bubble around inside him while veins bulge and nerves dull. He can hear Internal noises that range from groaning and gurgling to stretching, pulling, creaking, and hollow crunching. The subtle noises were growing more frequent and overlapped. Ryder knew this was the transformation starting and that was enough to stiffen his dick right up.

“I have visual, station one” Ginger’s attendant called out first.

“I also have visual, station four” said Nelly’s attendant soon after.

Ryder felt what had to be the changes triggered within him but suspected that he was still behind the others. Then Courtney shouted, “I have visual confirmed, three” from behind him and it made his heart skip. Then again when Courtney moved out of the way of the camera so Ryder could see what she had: a protruding bulge of flesh at the base of his spine. These were the beginnings of a proper horse tail.

A minute later and Shadow’s attendant called out, “Visual confirmed. Station two.”

“I have visual verification for every client and all vitals are within parameters. Attendants are cleared to move to the standby area until stage six checks. Good work, everyone,” Janelle thanked the exiting techs. Once they had left through a sizable sidedoor the four clients were left alone with Janelle and their transforming bodies. “My staff has cleared the room so you’re free to speak or verbalize to your heart’s content. I will be monitoring everyone through this and if you have any questions or comments you may certainly do so. Your head’s shift later in stage five. Meaning you’ll have twenty or thirty minutes to speak before you lose the ability. Do enjoy this unique shifting experience provided to you by us at The Farmstead Clinic!”

“Finally! It’s so hard to bite my tongue for that long. Especially when the changes start, mmmmm,” Shadow exalted and moaned as she, like the others, felt the massing growth at her tailbone. Bone, flesh, muscle, and a few stray curly hairs massed on the elongated dock of their forming tails. “How’s everyone feeling right now? Shadow is feeling mighty fucking fantastic,” she said with a shiver.

“Same, honey,” agreed Ginger. Who was transfixed on his many screens. “Always fun to watch the rear camera for changes like today,” he added, licking his lips.

“I always love the tail coming in,” Nelly shared, herself clearly getting a sexual kick off things. Unlike everyone else she wasn’t watching her screens as much as she was turning her head to see the others. Her attention is mostly on her neighbor Ryder. “And how are you feeling, Ryder? You’re oddly quiet and all sorts of nervous. Let me guess, first time?” she pleasantly observed.

Try as he might, Ryder couldn’t stop himself getting flush. “Y-Yeah. I’ve always wanted to give it a shot. The sensations are so… intense. Feels like it should hurt but it feels not so bad,” Ryder shared as the radiating heat that was pushing out his tail spread into his ass. Worming tendrils of change spread into his pelvis causing the man’s toes to curl and both his legs to tense up repeatedly. The others were doing much the same which had Shadow occasionally giggling from apparent pleasure.

“Oh yes, they make sure it feels anywhere from weird to wonderful,” extolled Shadow before an intense shiver passed over the woman's body. Her cradle swung but held fast as she came down from a very clear orgasm. “Whew, every time I’m here I cum right at the start of things. Stuff really gets the juices flowing.”

No sooner had she said it then Ginger could be heard to grunt and shiver as he lost it like his wife. He blew his load and was panting and sharing smiles with Shadow as both enjoyed the afterglow of things while their rears were visibly swollen with muscle and meat. The same feeling was taking Ryder’s rump and was stirring his cock pretty hard but the unusualness was keeping him from climaxing.

“Welcome to your first rodeo then, Ryder. You really lucked out when it came to company. Looking forward to some stud duty?” Nelly asked casually despite her cock dripping pre-cum.

The thought of being a stud had been on Ryder’s mind but hearing Nelly say it emboldened him a great deal. “I’m definitely looking forward to trying it. No idea how I'll manage,” a modest Ryder replied.

“I’m sure you’ll manage better than you expect. Once the transformation is so far along you’ll get that nudge from instinct. You follow that and the beast side will take care of the details. Just relax and let it happen, Ryder,” Nelly told the man next to her.

“Right. I’m trying to. There’s so many… feelings. It’s hard to focus on one,” Ryder said with a whinge. He watched the one screen in front of him as his tail took on length and his enlarging ass cheeks spread somewhat. Seeing his asshole puckering up under his tail was an oddly alluring image.

“Anyone wanna share their choice of breed or are we making it a surprise?” asked Shadow once she had recovered and felt the prickle of her first tail hairs growing in.

“Mustang,” Nelly blurted out while lustily chewing her lower lip. The changes edging her along.

“Apploosa,” announced Ginger. “My favorite.”

“Well then, thorough-bred for me. An all black one, big surprise. What about Mr. Studdly Ryder? What can we mares expect in the way of a suitor tonight?” Shadow asked with a haughty energy.

“Oh, uhhhhhh, what was it? Sort of slipped my mind. Give me a moment to, uhhh, gather myself,” Ryder excused himself, on account of a gurgling deep in his gut. It felt like gas was bloating up through his tender organs and occurred alongside the tingling penetrating him to reach his crotch. Wasn’t long until it oozed into his genitals. Dialing up his excitement and drowning out any aches from his bowels. “Shire horse. Black as well, I think. I forget what box I checked exactly.”

“I can’t remember either, if I’m honest. I might have chosen ‘random’ even this time. Matters less to me than breed,” Nelly said as calmly as she could despite her clear pleasure.

“I know I have a preference for coat color. Just like Ginger here,” Shadow said for herself and husband.

“At least when we’re horsing around,” added Ginger brightly.

“Which has been a lot lately,” smirked Shadow.

“Quite a lot, actually. So glad they’re always finding us new folks to partner up with. You both seem like you’ll be a lot of fun. Someone’s first time is always special,” Ginger remarked.

“I remember my first time. I almost hyperventilated because of how excited I was! Every time I feel my clit start throbbing that certain way I’m taken back to that first experience. I don’t know about you all but I’m not far from feeling that. I might get a little, vocal,” Shadow prepared the others.

“I’m a minute or two from that I think. It’s one of my favorite parts of each change. No surprise there,” huffed Nelly as she edged herself to the limit.

“Me too,” agreed Ginger. “Most that come here always love this part of the change. Get ready to really feel it, Ryder! I’ve experienced that stallion life before and it’s a surge like no other. Will feel like you’ve got a cannon between your legs!”

The suggestion helped fuel Ryder’s lagging erection back to full and leaking his own pre rapidly. He kept lowering his head to breath only to raise it again to watch his televisions- and sneak peek at his neighbor’s screens. Ginger’s were too far and at an angle to see but Shadow and Nelly were visible enough to see their backsides as stretched and massive as his. Shadow’s slit had darkened in color and started winking to his right. On his left Nelly’s balls were shriveled down to a small hole opening up above it, not far under her asshole. Seeing that hole steadily glow, absorbed her testes and enveloping her dick to steadily resemble the leather winking mare cunt that Shadow was well on her way to growing got Ryder going in just the right way to reach that climax he’d be racing towards.

“And he finally pops!” cheered Nelly who had been waiting for it.

Shadow moaned and gasped loudly as she orgasmed as she predicted she would when her clit expanded like she had been waiting for. Didn’t stop her congratulating Ryder despite gasping for air. “That’a… boy,” she said through clenched teeth.

“Th-Thanks,” Ryder smiled vaguely. As someone who kept to himself and never had any previous sexual experience it was awkward to get praise for getting off.

He had no time to linger on thought though with both hips and his testicles shifting drastically. The hips were changing his legs to hind legs; spreading his pelvis, swelling his lower back wider, his ass fatter, and perked his elongating tail up. Ryder’s balls felt like they were being tugged back as they ballooned in size. He was really feeling his scrotum grow to take up the new space created by a rump doubled in size since the start.

Hanging as he was in the cradle, Ryder’s ever growing testicles dangled and bobbled while the straps did their job of adjusting his increasing heft. He was really appreciating the added views the screens had given him of things he’d otherwise just have to feel out. Yet they couldn’t properly capture the twinge keeping his penis especially hard. Ryder’s blossoming thighs, developing flanks, and distended gut hid the sight of his cock from the side and his balls were too big from behind. He was a little disappointed but didn’t show it. Because he could still feel it engorging his length and girth beyond old limits.

“Feels so fucking good, doesn’t it? Like your body needs the transformation?” Nelly asked Ryder when she saw him bucking his hips ever so lightly.

“It really does. Holy shit, my… dick is going crazy. Wish I could see it grow. Stuff’s in the way,” Ryder admitted between gasps of air.

“Tell me about it. I feel new teats growing down there but have too much of a belly for it,” commiserated Shadow.

“Totally agree. I know I’ve suggested cameras underneath before. My teats have probably sprouted but can’t be sure until they’ve really filled out. Love seeing them sneak into view on the back camera. Almost as much as I love seeing my pussy wink and morph,” Nelly confessed without care for modesty. Janelle paid the comment no mind. Nelly’s transforming backside was, like the others, approaching an equine shape that stretched all the way down to her ankles. The heavier her thickening legs got the more it tugged Nelly’s butt in ways she clearly enjoyed. She glanced over at Ryder again and loved what she spotted. “I spy with my little eye something black, veiny, and studly.”

“Wha?” Ryder half-heard Nelly. Unaware his cock was nearing a foot long and conspicuous. Every beat of his heart resonated down into his member; fattening its girth, adding more length, swelling the veins, and spreading a dusty black coloring up from the hilt. The head of Ryder’s cock was flesh colored but the tip was flared and more stallion than man in shape.

“Oh! I know! Our very own Ryder’s stupendous and seriously substantial stallion shaft!” proclaimed Shadow who sounded drunk on arousal. She’d also taken up staring between Ryder’s legs at the emerging rod. “Hehe, I hope you don’t mind if I ogle your bits, Ryder. I’ve got hungry eyes,” she purred and licked her lips.

Ryder took note of the many eyes on him. Which included Ginger as well as lead tech Janelle. “Guess I do have to get used to… being stared at,” grunted a grinning Ryder.

“Modesty is out the window when you’re a farm animal. I find the communal aspect one of the… things I enjoy about these sorts of adventures. Really gets my blood going,” Nelly revealed despite wincing repeatedly throughout. The cause was her cramping toes in conjunction with the bone and flesh of her feet extending. She was the first to feel it with the others not far behind. “And you guessed right, Shadow! Let’s be honest, not hard to answer. Can you see it yet yourself?”

“No, n-n-not yet,” stammered Ryder. On top of those changes already transforming his penis an excess of dark horse flesh at the base had built up at the base. As his cock crested past a foot in length that excess skin began working up the shaft in a way that stimulated the sensitive flesh. It also spread up his abdomen, stitching his cock in the beginnings of his sheath. Resulting in more heavy breathing while Ryder dealt with growing sensory overload. “Now I can… see. Oh wow that’s… that’s me?” he asked in disbelief as he peered at the side view cameras.

“That’s you for sure, stud,” Shadow affirmed heartily.

“It’s as much you as your tail. Both look cute on you,” complimented Nelly.

“I know which I’d rather have in me,” remarked Shadow with a snicker.

Nelly laughed only to hotly gasp and moan from her first equine orgasm of the day. There was a squirt of fluids from her freshly finished and functional mare cunt that dripped onto the grated floor under her. “I’d think that answer is obvious for any of us,” she finally said once she could speak again.

“Y-Yeah,” nodded Ryder, trying to follow along.

“Fuck yeah,” Ginger grunted as he too has his first orgasm down at the end. ”Just thinking about stallions got me. Holy shit, it’s more intense than I remember,” he said of his body shaking climax.

“They’re so great, aren’t they? Even better when it mingles the changes themselves. Works with hooves so good I can’t help but make a mess,” Nelly shared while her cradle rocked.

Pulleys and clatter of their straps adjusting blended with the wet crunches and cracks from their transforming backside and overlaid their collective moans, groans, gasps, and whatever else came out of their mouth. The room had gotten considerably hotter in just those first few minutes with all four radiating enough heat that it was steaming off their backs. Their cradles keep their spines in line while actively adapting to their constantly expanding width and weight. All equipment and vitals were working within safety parameters to Janelle’s experienced eye. While her clients were taken with their new genitals she closely monitored the progress of their feet. Once they were hooves across the board the tech could push them to the next stage.

It was getting harder for Ryder to keep his thoughts focused on the same thing for more than a few seconds at a time. The feeling of his cock swelling to equine proportions had been something he’d fantasized about for years. The actual sensation of both his dick and nuts sizing up to a stallion’s had him aroused and excited. When he saw it in the screens- best seen in the right side camera or from behind where most of the view is his melon sized horse balls- however he couldn’t fight an unnerving feeling of how foreign it actually looked. How all of what had so far changed looked. In his imagination things had never been so real or graphic. Seeing hide and hair coating his ass and thighs, a tail he could flick and move, and a massive butt that was still getting bigger. Watching his anus shift up his tail to protrude and pucker had Ryder fighting back gagging. The first hints that he might have gotten himself into something he couldn’t handle.

Hooves developed on his and the other’s feet from their merged central three toes and their former nail beds. This left the outside toes to dwindle and blend into the fetlocks or pastern portions which were also taking their shape. To Ryder it was more weirdness on top of what was already there. Having no more toes to curl and those heavy masses in their place was adding to the unusual. The others were all quite happy to have hooves. Nelly was delighting in hers nearing completion- minus furnishings- by stretching her legs out enough to clatter on metal grating under her. Which started the couple doing the same.

“You don’t want to join in on the cacophony, Ryder?” Nelly playfully chided the man who was the only one not testing their newest additions.

“He looks positively cross-eyed. Suppose two feet and change of horse dick under you might do that,” an over-aroused Shadow tittered.

Her words reminded Ryder of that growth under him and his doubts were assuaged by the deep pleasure stemming from his cock’s continued changes. By that point his hooves were formed and legs were darkening with hide and horse hair was painted a muddy black and bore no resemblance to the human penis he’d had. The sheath was partially developed up to his lower stomach but like the rest of the transformation that’s where it halted. Ryder looked at his screens and could easily see the partially erect equine dick drooped under him. Every lustful throb he felt he saw and continued having trouble processing.

When he looked at Nelly and Shadow’s screens their butts were undisguisable in front of their chosen breed. Their dark udders were indeed visible from behind to complete the look. Nelly’s coat was coming in a bay color that shimmered in the various lights while Shadow’s thoroughbred black shinier still. From what Ryder could see Ginger’s white rump dappled with chestnut spots. That went doubly for him as his hairs were more horse so lacked quite the shine. What he lacked in a glimmering coat was easily made up for in his sizable hindquarters and legs. Well muscled with tail hairs that nearly reached his hooves it was a lot of horse to be attached to a man. Most daunting for Ryder was wielding a stallion’s genitals with a man’s head as he danced between lust and lamenting getting into this at all.

“Well everyone, how are we feeling so far? How is having a horse’s backside?” Janelle asked brightly as she prepared stage four for all cradles.

“It’s been divine so far, Janelle. You and your crew do miracles,” gushed Nelly with another shake and stretch of her equine form.

“Fuck hot as hell miracles. Worth every penny, every time,” stated Shadow in a sultry voice. She was still staring at Ryder’s cock and unlike him very much loved the look of it; letting it fuel her towards an orgasm between stages.

“You’re too kind, Shadow! And thank you for those kind words, Nelly. How about the gentlemen? Thoughts? Jokes? Comments?” As Janelle busily worked, the furnishings of all the guests had time to come in. Wonderfully accenting their hooves and hind legs to really complete the lower half of their bodies.

“Absolutely loving it. So ready for the rest… backside is hot. I’d also say our guy Ryder over there really won the Triple Crown today,” Ginger quipped in a quavering voice. The mares-to-be and tech laughed while Ryder didn’t quite get it. If he wasn’t under the impression that Ginger was going to be a stallion like him then he would have known that he had three mares to crown that day. Not the two and competition he currently assumed to be joining. He let it go rather than worry about it.

“I like that. Getting mounted and crowned sounds like a great afternoon,” panted Shadow.

“Mmmm, I love the vibe in here,” remarked Nelly with a touch of Shadow’s playful lust.

“And you, Ryder? How’s your first equine adventure going today?” Janelle asked the man directly.

“It’s, uhhhh, really something,” a red and sweaty faced Ryder answered after a time. The reason for his hesitation is neither the horny desires brought on by his horse junk or a hard to dismiss feeling he’d bitten off way more than he could swallow. A gurgling in his guts and bowels that had begun almost when the changes had was currently churning distinctly in his bowels. So much so that he was clenching his asshole tight as could be when Janelle was asking her question. “No pain or anything. I’m good,” he fibbed. Holding back his misgivings and growing need to relieve him.

“Wonderful! Sounds like we’re ready for stage four! So without further ado, let stage four hooves to the floor commence!” With that Janelle initiated the next stage in things; triggering the auto-injection of through several tubes into each cradle.

“Things are really gonna heat up now, I fucking love it,” Shadow swooned as she and the others felt the drugs enter their veins. First washing through their rears before rushing into their top half. The succeeding spasms had everyone clenching their hands. Only Ryder was feeling fright in addition to urges towards incontinence.

“Let’s keep this party going! Hell fucking yeah!” cheered Nelly once her teeth stopped chattering.

The transformation that had stalled mid-gut restarted with a vigor and bloat. Everyone was sporting a gut to some degree- stallion Ryder’s the largest by far- but this stage kept going into the stomach, kidneys, diaphragm, lungs, and every other organ in the torso. To match the spine and increasingly the ribs beefed up which caused some of the loudest, unsettling crunching and popping noises yet. None of it dissuaded the three experienced adventurers as they reveled in their expanding frames.

Things were different for Ryder. Thanks to his big meals and inability to be upfront with the techs he had a horse sized shit to take and nowhere to take it. The only plan Ryder had was to hold it in until it was appropriate to go. That plan crumbled after a couple minutes of ballooning size and accelerating digestive processes. The indistinct churning had become solid and barely held back by his flaring anus. Ryder’s slim hope of riding it out ran out of gas.

“Don’t mind if I start going a little quiet. It’s always tough while the lungs are expanding,” Shadow said as her breathing became erratic. All of them faced the same problem to varying degrees.

“This part is always the-” Nelly was saying when Ryder let out a loud, wet fart to cut her off. The stink didn’t take long to propagate. Helped along by more flatulence that Ryder was trying and failing to control. “Whew! Ryder, honey, are you okay? Because you don’t smell okay,” she asked while trying to hide her aversion to the stink.

“Smells like manure,” Ginger commented.

“It really does, doesn’t it? This soon?” wondered Shadow. Then smiled wickedly despite her puffing for air. “Same thing happened when Ginger partied with friends the night before we were doing the donkey adventure. I didn’t know about it until he was making just like Ryder with the gas,” she recalled as she locked eyes with the group's only stallion. “Naughty, stud. Janelle’s gonna be mad.”

The aroma reached Janelle last but wasn’t any less potent to her. She’d had her head down but it shot up at the sounds of horse flatulence. “Okay, who is that? Ryder? Is that you we’re all hearing and smelling? Did you fail to mention eating anything in the last twenty-four hours? If you did there’s no reason to lie at this point. You won’t be able to hide it,” she asked in a sterner tone while coming out from behind her station towards him.

Ryder felt the embarrassment of all eyes on him. His face was already red so his blush was well hidden at least. “I did. I’m… sorry. I got nervous and it was… stupid and I shouldn’t, ugh… Fuck this was a mistake,” he whimpered weakly.

“Yeah, eating and not telling us was. It could cause serious complications or problems potentially for some patients. And even if it doesn’t, we’re just gonna have a mess to clean up. Aren’t we?” Janelle challenged. Then, hands on hips, waited for Ryder’s self-control to crack.

“I… I… Shit,” cursed Ryder a few moments later.

They all watched Ryder lift his tail and saw or heard him release a tumble of turds behind him. They continued to push out en masse after that. The other transformees were sharing a mix of laughter while Janelle returned to her station without saying a word to the man. She did make a page.

“Will cradle three’s team report to the main shifting area for a code brown and likely code yellow. Bring a sack,” Janelle ordered into her radio.

“Sorry. Sorry,” Ryder repeatedly apologized again. For what he’d done and for his correctly predicted need to drain his bladder too.

Courtney and her fellow tells reluctantly returned through the door they left and marched to tend to Ryder. Once he had started there was no stopping Ryder’s body from emptying itself like any full up horse would. The disappointed look from Courtney and the other techs didn’t help things. They cleaned up what had fallen and affixed a large leather catcher to the cradle behind Ryder to collect going forward. His piss was passing through the grates under him but they still sprayed a foam to handle the pungent smell. There was no denying anymore that he wished he’d stayed home that day.

None of it slowed down the transformation’s progress into the chest, shoulders, and arms. Ryder couldn’t look anyone in the room in the eye so he peered down at the ground and himself. His shoulders were actively spreading and bulking which in turn shook his dangling arms which had just begun to shift themselves. The area of his biceps had grown stockier and forearm longer and wider. A twitch in his fingers was uncomfortably similar to the sort that took over his feet.Then his middle and index fingers were sticking together.

About the time Courtney and gang shuffled out of the room Ryder had to be having his hands melt into bulky hooves. The others were thrilled to be gaining the match set to their rear hooves. Nelly and Shadow were so eager they kicked their shifting forelegs in an effort to be the first to touch the floor. Ginger was happy curling his newest hooves under him and being able to breathe normally. Albeit with loud, heavy breaths out of a still human sized neck and head. The look of all of them at this awkward stage of things brought back the smile to Janelle’s face.

“It’s your first time, Ryder, so I’ll cut you some slack. Keep this in mind for future adventures. If you become a repeat offender of this rule we will have to ask you to leave and ban you from the premises. With the air close enough to clear and you all progressing wonderfully, I’m going to get ready to initiate stage five. That’ll bring all cradle occupants over the finish line. Just need a minute or two,” Janelle told them all as she busily typed.

Every cradle had their respective occupant suspended and leveled so unless they stretched their hooves hung a few inches from the floor. That went for burly Ryder and his chosen shire heritage. While the three mares were close to weighing a thousand pounds each, the black shire stallion was two thousand without his stage five changes. It showed in his size but weight mostly. To the man inside whose head was a tiny thin between towering equine shoulders there was more fear than anything else. Ryder knew well that there was no way else through this than letting the transformation and this adventure run its course. But he was rather sure he’d have to let the two mares down. Then it would be a matter of waiting out being human again.

‘I should have started with something easier. Maybe a hybrid or something. But no, I had to go all in on being a stallion because I thought I’d love it. This is way more than I can handle. I wanna go home,’ went bitter thoughts in Ryder’s head.

“Take us home, Janelle!” Nelly clamored in a deep, resonating voice.

With some effort Shadow was flexing her front legs together to clop her hooves. “Wooooo! Horsey time!” bellowed Shadow in a similarly deep voice.

Ginger mirrored his wife’s horse clapping as he awaited completing what had started.

“Yes, yes, I’m on it. I’m confirming stage four completion across the board which pushes us to stage five. Heads up, you will feel this,” Janelle humored them in addition to triggering the last set of injection cocktails in their veins.

The effect was more intense and immediate than the last two doses from the very start. They were all clenching their teeth and pushing their foreheads into the padded headrest on account of the forcible growth rippling up their necks from their barreled chest and breast. Very quickly their necks swelled from muscle, bone, flesh and thankfully their windpipes to stretch them out from their bodies.

“Who wants to be… mounted first?” Nelly had the sense to ask, her voice getting ragged.

“Me please! I’ve got no shame, I’m fine saying it,” an unabashed Shadow stated.

“I wouldn’t mind first but I don’t mind second either. Not like we have much time to, hrnngg, argue. You okay with that Ginger?” Nelly hollered across the room.

“Sloppy thirds are good. I always need to let it sink in anyway,” huffed Ginger.

“Glad we could be civil before we let loose with instincts,” Nelly hooted as she felt her skull tingle.

Ryder wasn’t paying close attention to the chatter beyond knowing it was about his function as a stallion. Everyone was having such a good time he didn’t want to be a bucket of cold water on them while they were transforming because he lost his nerve. Better to keep quiet like he had a habit of and tell them afterwards. Until then it was surviving the incoming transformation of what little human was left of the man.

Slow and steady their necks elongated, bulking and sprouting manes as they developed. The changes got ahead of themselves to at last get to work fixing their heads. Their ears were tugged at the sides and reshaped at the tips. Noses and soon mouths and entire faces broadened. Everyone was losing their hair, eye color, pupil shape, and then came their muzzles. Thick lips hid their old teeth being forced from their gums and soon spilling from their mouths. A literal nightmare come to life for Ryder.

Their skulls vibrated with the amount of changing bones and flesh going on. As their new, fat, and flat horse teeth bud into their lengthening muzzle there were chattering teeth and flashes of white-yellowed grins. Ryder was having trouble keeping his head up and unlocking his lower jaw until his skull was suitably equine enough. The whole time he could hear the loud breathing through his nostrils and the wheezing whinnies escaping every now and then from his mouth. His regret was close to palpable and seemingly the only thing that couldn’t change.

Come the passage of more time and less than ten minutes from a stallion, Ryder’s senses become akin to the stallion’s whose body he nearly shared. This tipping point caused a curious transformation Ryder hadn’t suspected; one in his research that went through a person’s mind when taking on a horse’s instincts. Keeping human intellect was a big reason he chose this option but the promise of experiencing equine was fulfilling itself in every new breath the stallion took.

Ryder’s human nose had smelled the mess he made and some of the cleaner. Compared to the stallion it was poultry. There was still the manure and piss but he smelled his dander, his own heady, raw, strangely virile scent. From there he was drawn to steamy, flowery, and moist aromas that perfumed the air. The more he smelled the better he distilled three distinct scents that his balls and brain indicated belong to nearby mares. Realizing that and his growing erection, Ryder put regret and doubt on the back burner for now.

“Five more minutes, everyone. Homestretch!” declared Janelle, laughing to herself. “Heh, I love that one when it's horses or donkeys,” she said mostly to herself.

Nelly and Ginger whinnied the best they could. Meanwhile Shadow and Ryder were eyeing the other’s screens with renewed interest. The experienced adventurers knew to let the thoughts in but not to give them full control. Ryder was told and informed as much beforehand. Yet perhaps driven by a need to stamp out fear of getting himself in too deep he let himself give in to desires very much born of a stallion’s mind. That allowed Ryder a great comfort in his body and not so much revulsion when viewing themselves. He may even have been growing to relish what he saw.

Pins and needles spread down from where their neck and mane had finished growing to. Hide and hairs rapidly covered all four of their long, equine features to finish what had started with a few hairs on their new tails. Shakes and shivers went through them all as things finished. Shadow and Nelly used the moment to achieve one last orgasm while their bodies were still in flux. Joining them for the first time in climax was Ryder; christening his cock with a massive release. The scents of all the mares in heat around him- one more than he could account for- and the knowledge they wanted him was enough to push him over the edge. Putting him a long way from his recent regrets.

“And…. we… are… done! I am showing green across the boards in all cradles. Tech crews please prepare for stage five completion and commence vital and safety check,” Janelle announced to both the clients and her radio. “Another successful, if a bit messy, shift. I’ll take it,” sighed Janelle who took a moment to wipe down her station's steamed up monitors.

The whole experience and that orgasm that capped it left Ryder tired, thirsty, steaming hot, and dripping fluids. He’d almost filled the sack set up behind him with manure. The result of those final intense spasms near the end that flushed what was left of his bowels. It was easier for Ryder to think now that his body wasn’t shifting species. He did have human thoughts and reason to gather but the presence of bestial instinct was undeniable. Lifting up his head as Courtney and the other two techs rolled up to him took a lot of effort.

Things were hazy as Ryder came to grips with eyesight that was down a horse’s face and couldn’t distinguish reds. They had brought with them a mobile station for their equipment and tools as well as a space on top for a four gallon rubber bucket. Inside of which was a pink-green colored water that they positioned right in front of him to drink.

“Okay all my lovely horses, we’re going to do some final checks on you all to ensure all is well before we move you to the next stage. While we tend to such things please enjoy this water infused to help rehydrate, recuperate, and reinvigorate you in a jiffy. By the time you’re finished we should be ready for stage six and getting you to your pre-prepared SAFE room. So relax and drink up, mighty steeds,” encouraged Janelle.

Nelly, Shadow, and Ginger had begun slurping up their buckets once before Janelle had said her bit. Ryder’s thirst had him salivating, eager to join in. Actually drinking the way took some getting used to from the first time horse. He mostly splashed it around and had it leak out of his mouth before he could swallow any.

“Relax, Ryder. You’re overthinking it,” Courtney coached the stallion as she removed the harness on his head.

Ryder did his best to take the advice to hand; closing his eyes and letting simple instinct guide the way. He fumbled a little at first but got the hang of it and was chugging it down with the rest of them. That earned a pet on the head from Courtney.

Checks and diagnostics were run and passed as one after another the four occupants were removed from their cradles. Each one landing first on their back hooves and then the front making a loud clatter. None was louder than Ryder’s stocky heft coming down to stand of his own accord. Ryder was a little wobbly legged but the drink and a few injections he didn’t notice restored the weakness in his muscles, tendons, ligaments, and joints.Those techs at Ryder’s station had the extra pleasure of removing his manure bag to be incinerated with the rest. The remaining diodes and clips were removed from every horse and bridle fitting to their heads once they finished their drinks.

Last to be bridled was Ryder after his slow start drinking. Courtney remained close to the stallion, holding his reins and directing the other two techs securing everything. His thirst was quenched for the time being and his body felt as normal to him now as his old one had. Only with a slightly surreal facet to it all. He looked to the other horses and saw them all standing at the ready, muscles flexing and tails flicking happily. They each had one tech holding their reins while the others were already on their way out after signing off with Janelle.

“And just like that we are on to stage six, everyone. Please follow all instructions given by your handler and follow them to the lifts. From there you’ll be brought up to your Simulated Adventure Farm Environment, or SAFE, room on level one. I will see you all there for a final briefing before the best stage of all: seven.” As soon as Janelle made her announcement the three mares in the room excitedly whinnying for the future. Ryder joined in, snorting and whickering despite not fully understanding why.

Courtney and the other handler techs lead their horses to the far end of the room from where they had entered. Behind some curtains and around a corner there was a bank of three elevators intended for lifting very heavy freight. The doors were extra wide and tall and inside the two waiting lifts was space for all four horses if they didn’t mind keeping close. For weight concerns they had two handlers and two horses on one lift each then sent them up. That put Ryder and Ginger together while Nelly and Shadow took the other.

As Ryder waited and tried to keep still while standing beside what his beleaguered brain still thought was Ginger the appaloosa stallion. The smell coming off Ginger was a dead giveaway that wasn’t the case. A cursory glance with a stallion’s eye told Ryder that Ginger was actually a mare. Confirmation came when they reached their floor and Ginger was the first to be led out the door. Giving Ryder a perfect look at another mare’s inviting backside. The prospect of being the only stallion with three willing mares was enough to please human and horse parts of the man’s brain. Courtney had to tug his reins a few times to shake him out of it and get him out of the elevator.

The four horses were reunited right out of the elevator and did not have to walk. They were let out in a small lobby with three sets of double doors numbered individually with ‘SAFE Room’ signs. Room one is where the handlers led the horses with Janelle the one opening the doors from within to greet them.

“Come on in, folks! We’ve got it all ready to go! Two acres of simulated pristine farmland all to yourselves for the next seven hours! Keep close to your handler and only wander off once we’ve covered some final matters. Please, take it all in,” Janelle invited the four.

They entered the SAFE room through the facade of a wooden barn that then opened up onto two square acres of real grass pasture. It had a couple hills and even a few apple trees. A wooden fence enclosed it all while the three story high walls had projected scenes of bucolic pasture land stretching over hills to distant mountains. The similarly simulated ceiling showed a slightly cloudy but very sunny sky that matched the warm, balmy temperature they felt. There was a breeze that brought the smells of wild flowers, grass, wood, water, oats, hay, and the outside. There was a hint of the artificial to it but not so much that any of the horses couldn’t lose themselves in the careful simulation.

The final briefing was mercifully very brief. Janelle laid out ground rules about behavior, consent, safety, and where they could find food and water at any time. Generally they were allowed to do anything a horse would do and so long as they didn’t endanger themselves or others, and they respected consent for any fooling around, they were free to spend the seven hours however they wanted. Their bridles were removed and the handlers stepped aside to leave Janelle finishing up her instructions to the four very anxious horses.

“We’ll be monitoring at all times but won’t interfere unless there is an issue until the very end of your session. At which point we will go through de-shifting protocol stages. But enough about that, it’s time for some seventh stage of heavenly fun. Is everyone ready for some horseplay on the ranch?” asked Janelle for fun as the answer was pretty clear.

The horses whinnied, reared up, stomped their hooves, and showed their eagerness to get to their horsing around.

“Thought so. Well I say, on behalf of everyone here at The Farmstead Clinic, enjoy your stage seven adventure!” Janelle hurried to the side and let the horses go at it. Which they all did at a gallop; airing out their legs to burn off their overflowing energy levels.

The doors to the room were sealed and the horses left to their fun. Something they got to within a few minutes of running around the sprawling premises. Ryder couldn’t hide how distracted he was by all the sight and smells of all the mares around him so the three experienced pleasure seekers corralled the stallion with their bodies far off in the pasture. Their bodies rubbing against his have Ryder’s cock sliding from its sheath, like the mares wished. Heating up until Shadow took center stage to be the stallion’s first prize.

Those regrets Ryder had seemed rather foolish as he mounted Shadow with heated desire. Fears that he wouldn’t find a mare attractive with human intellect were unfounded thanks to influence from his new body. Remaining trepidation disappeared when Ryder’s cock found its mark. It did take a few tries and the nuzzling of his dick into place by Nelly and Ginger for Ryder to hit his mark. From then on through thrusting and humping he forgot what regret was. There was just lust and how to satisfy it. The sweet release of his seed into the eager mare proved intoxicating. It was so raw, unabashed, and brutishly equine that it was hard for Ryder to not give in completely.

There wasn’t much downtime between dismounting Shadow and getting Nelly as Ryder proved his stamina was a match for his virility. Mounting Nelly was an even sweeter experience than Shadow as the mare moved her body in ways that showed she was loving it as much as him. He surrendered further to his desires when he emptied another big load into the mustang under him. Ginger didn’t wait longer for her turn under Ryder’s shire heft. She acted like a more inexperienced, doe-like partner that Ryder’s rough stallion side loved taking. This time when he came it was like claiming a prize in the stallion’s mind. A mind that had come to dominate Ryder’s thinking.

‘More. More! More!!’ Ryder thought every time over the next several hours he mounting and fucked any of the mares. They felt to him like a harem that needed tending. Only a strong male like him could keep such a stable. Less and less of the thinking came from the human parts of his mind. At some point, likely while mounting Nelly for the fourth time, the stallion switched to make all the decisions in the body. And any human thoughts were buried by the stallion’s dominant nature. A few final self-reflective thoughts saw what happened and remembered regret one last time before the beast took over.

********

It was evening when Nelly, real name Layla, was making her way out of the Farmstead Clinic office’s network of hallways. She’d just been discharged after undergoing reversion back to her human form and was heading home to change before heading out later that night with friends. Unlike the shared experience of changing together, the change back to humanity is carried out in separate rooms with computers controlling the individual user. After Layla was her old self she was taken to her changing area of the Shifting room where her locker was. She’d missed saying goodbye to the couple by a few minutes while being told the stallion she knew as Ryder was still being processed.

Layla always disliked that aspect of how this clinic ran things. People were rushed out afterwards instead of having a chance to mingle, swap information, and perhaps arrange future adventures together. They said it was in the name of privacy but Layla figured it was more to do with turning over more customers. It was a shame since she had intended to give Ryder her phone number. For a first time, while a little shaky at first, he became a real natural beast after a few mounting sessions. Someone that took to adventurers that well was worth knowing in Layla’s book.

By chance not far from the exit Layla almost collided with lead tech Janelle as she was going to clock herself out for the day. Giving Layla a chance to thank the woman having not seen her during discharge like usual.

“Glad I didn’t knock you over there. Was a great session today, by the way. I quite enjoyed the group composition this time around. Never thought three to one on that would work out but when it's one like that? You all are wonderful here. Really,” Layla reiterated gratefully.

“Glad to hear you enjoyed yourself! Thanks so much for the kind words and I’ll definitely pass them on to the team. But…” Janella hesitated to finish.

“But what? I thought it went great!”

“It’s about the composition. I have a hunch that the three to one variant will be shelved for the time being except for parties with experienced members, like yourself,” she explained. Raising more questions.

“Shelved? Why? Because it would be too much fun?” Layla joked.

“More or less. I know I shouldn’t be telling you this but,” Janelle paused to lean in closer to Layla and continued in a whisper, “The stallion, Ryder, the newcomer, has what we in the industry call DDLS. It’s a shorthand for ‘Daniel Day-Lewis Syndrome’, where a subject gets so lost in their transformation that they can’t come back. At least not immediately. Ryder is currently in our DDLS holding area while they wait for him to cool down. Happens with some first timers rarely and always when there is a lot to sexually stimulate them. I didn’t arrange the pairing but our scheduling team likely won’t make that mistake again. Legally he’s the clinic’s problem until he’s back to normal. It’s a whole thing,” she explained at length.

“Huh, that would explain some of his behavior in the second half of the afternoon. How long does that sort of thing last?” Layla asked with moderate concern.

“Could be a few hours, days, or weeks even. He’ll come around though. Sometimes they just get in over their heads. What can you do,” Janelle shrugged.

“Well that ruins my idea. Was going to have you pass my phone number to Ryder if you could. Damn. Well, at least I know he had a good first time,” smirked Layla.

Janelle moved a little closer to Layla. “If you give me your number I’d be happy to give you a call sometime,” she flirted unexpectedly.

Blushing, Layla fumbled for her business card and handed it over. “Can call tonight if you want. I was going to meet some friends for drinks and-”

“I’m leaving now and can I meet you out front in 10 minutes? I know a good place for Thai around the corner,” Janelle suggested as she pocketed the card and laid on the charm.

“O-Okay, sure. So long as you don’t mind me without makeup,” a now bashful Layla remarked.

“If I didn’t mind you as a mare I wouldn’t mind you now,” replied Janelle while pulling away from the blushing woman. Something she found rather adorable. “See you soon!”

The exchange left both women hurrying off for their impromptu date where they’d speak of Ryder’s situation more. The man himself was presented in a stall between a cow and deer with no notion of himself as anything except a stallion for all of his days. It would be two more weeks before Dennis saw sense and could be brought back to humanity and two legs. He’d walk out of the clinic with clear memories of his time transformed and lots of worries about whether he’d been fired or not from his job. Yet he wasn’t feeling regret about his first time. Dennis was already thinking about a second.
