Walking out into the warm evening air, Tina smiled coyly at her boyfriend before the two of them got into their car. It had been a pleasant session, all things considered, and the two of them were riding high. It was not that they needed to go to couple’s therapy, at least not in terms of saving their relationship. But having been high school sweethearts, Corey and Tina had watched several of their friends break up over the course of their college careers, and with their love for each other, they didn’t want the same to happen to them. So in order to make sure any potential issues were caught early, the two decided to start couple’s therapy.
Much to their relief, it seemed their relationship was on track. Their communication skills were well practiced, and even though they were often busy with college courses and then like, the two made regular time for date nights. Having a healthy amount of time within their own social groups and hobbies, it seemed like the basis of something special and lasting. Still, the therapy sessions had been worth it for a variety of reasons, of no small bonus getting to know things about each other that had never come up before. Hell, the two of them even looked forward to the sessions and would be sad when the therapist’s program was finished.
Having been familiar with their therapist’s methods for some time now, the couple was surprised when she presented them with a pair of pills, something she had not implied she would prescribe. They were quickly given her assurances that it was something she regularly offered her clients once they had reached a certain point in her sessions. Not sure what they were for, Corey and Tina gave each other a look, having not needed either medication or anything more exotic to have their fun. Yet, their therapist was insistent, assuring them the pills were tailor-made for their particular proclivities. It was something she had managed to formulate based on their personalities from a quiz she had them take during their first session. While she did not require them to ingest such, she insisted their use would help in their overall relationship by exploring something intimate and special with each other.
Giving them a set of instructions, she set them off with the pills, and both were left to think about what they would do on the car ride home. Her advice had been helpful thus far, after all, and Tina was inclined to give them a try, regardless of what the end result was. Corey was more timid about it, not sure why such an ambiguous medication would help them with their relationship. But his girlfriend had never led him astray, and in the end, Corey agreed regardless of what they might be for. Besides, they had all night and the next morning to enjoy their results, as she’d informed them. Even if they weren’t the most legal or safe, it shouldn’t hurt them in the long run!
Both of them had been given specific pills, though the fact Corey’s was pink while Tina’s was blue was a little perplexing. “Are you sure these are the right ones?” He asked, though not for the first time.
“She was pretty specific,” Tina replied, before grabbing a glass of water and taking hers in one gulp. Corey was still a little hesitant but figured there was little to be done. Forgetting he hadn’t grabbed a glass, he moved to the kitchen before heading back to his girlfriend.
In truth, Corey had no idea what to expect that sort of pill to do. Part of him assumed it might have been for sexual enhancement. Such was just as likely to be a placebo, but either way, they weren’t being charged anything additional for the pills. And they had one more appointment to see their therapist to discuss how they felt about the results before ending their time with her. They trusted her enough to take whatever supplement she saw fit, and she was a trained professional, right? Then what was he so worried about?
Tina, to his surprise, was rubbing her skin a little, as though a prickling or itching was bothering her. She didn’t seem to notice him return at first, rather concerned about some phantom sensation she couldn’t quite place. Corey went to ask her what was wrong when her hands suddenly went to the back of her pants, rubbing around her tailbone. It took him a few minutes to notice what might have happened, but the sight of a lump made his blood freeze. Something was sticking out of her back, pushing at her panties and making a noticeable bulge. Almost like she was growing a…
Without hesitating, Tina reached into her panties to pull out the growth. Turning around with a look of shock on her face, she regarded the full-length mirror to see the lump push outward, getting steadily longer as they watched. While it remained skin color for the first few moments, a spread of orange and yellow across it left both of them confused. As though rapidly growing weeds, hair continued to push out, so thick it was hard to see the skin. The growth continued to work its way out of her spine, long enough that when it twitched, both Tina and Corey jumped. Yet, as she focused on it, it seemed she was able to make the growth swish from the base, hairs getting longer all the while and tickling the back of her thighs. It looked to all the world like a horse’s tail, accented with fiery shades of hair that did not exist on any natural-born animal.
Corey went to call out his panic, though was rather surprised when Tina spun around, a grin on her face. “This is amazing!” She declared, allowing her tail to swing back and forth as its hair grew to what they assumed was its final length. Owning such a thing was impossible, but the expression on her face was one of pure delight.
“What’s happening to you?” Corey questioned, but it seemed Tina wasn’t listening. In fact, she was turning around for him, showing off her back as a trail of the same flame-colored hairs started to lance up in a line above her new tail. She delighted in the sight of it, reaching back to tease it into existence. It was soon accentuated by the growth of off-white hairs, something Corey didn’t notice immediately over her skin. They quickly grew into several small patches that spread to touch each other, forming what he could only figure was a pelt of fur. It seemed to itch her somewhat, both hands running over it as an expression of annoyance crossed her features. Hell, as best Corey could tell, it was even moving down her ass, as though her body was meant to be covered with a coat entirely.
“I don’t know, honey, but I think I like it!” Tina exclaimed, lifting up her shirt to feel the growing fur. Still, with his concern over the changes, Corey could only stare in silence. As he figured, the moment Tina reached down into her pants and even her panties, it seemed her skin was covered with a fine coat of glossy white fur, with no signs of stopping.
Of course, the implication was not lost on him as an ache in his own spine came to his attention. Still, he didn’t want to reach down and acknowledge the fact he had taken his own pill. There was every chance he was about to undergo the same thing, and the more he watched Tina’s change, the more he feared for himself. What the hell had they gotten themselves into?
Tina, for her part, was still reveling in the changes, rubbing more fur over her back and beginning to tease her chest. The alterations were more than surface level, as her skin seemed to ripple and stretch. It was likely her muscles were tearing and expanding in rapid succession, bulking her up in a way that defied her formerly petite frame. While she had still decided to keep her clothes on, they were starting to get tight, as though the muscle she was putting on was meant for something larger. Even her 5’7 frame seemed to be getting a little taller, as though her legs and chest were stretching ever slightly.
The idea of what she could be changing into escaped them both, and Corey went to call out to her as Tina reached to rub her forehead, as though something was paining her. Moving her hands, both stared with rapt attention as a pointed growth worked its way out of her skin. While it was bloodless, the protrusion was pushing upward with alarming speed, as though reaching for the ceiling. It seemed to be smooth, and conical in shape, and its point wasn’t particularly sharp. The sight of it, in tandem with her tail, drew images of a unicorn, though it was hard to be sure. While its color was strange, his interest in fictional characters drew his mind in a certain direction, though not one he would ever expect to see in a real-world setting.
Both of their suspicions were confirmed as the fiery fur moved toward her own hair, shifting it from its brown toward that combination of orange and yellow. As great as their love of Pokemon had always been, the image drew something akin to a Rapidash, save for the lack of real flames. That might have been too much, though now he had the thought, there was no denying the similarities. Yet, how was such possible? They had mentioned Pokemon perhaps once during their discussion of similar hobbies, and perhaps in the quiz as well. Not only did their therapist recall that, but provided them a pill to allow them to change in such a way…it was too much!
Almost forgetting he, too, had taken a pill, Corey was shocked to feel a growth pushing out of his spine, painless though rapidly filling his pants. As much as he wanted to deny its presence, he had little choice but to reach back and pull it out, showing it off to Tina. The moment his fingers pressed against it, he was aware of a rather soft, fluffy texture, unlike anything he had felt before. Had it not been growing out of his ass, he might have found it pleasant!
“You have one too!” Tina declared, giggling. As Corey pulled the curved, silvery blue appendage from his pants, its color gave him some level of excitement. The tip blossomed out into a spread of fluffy fur, and though it made little sense on his own body, the mental image was not entirely unwelcome. There was a favorite Pokemon of his that sported a similar design, and he could only hope that was his fate, regardless of the outcome.
A growing tension from either side of his new tail led credence to what he had hoped for. It seemed the bones themselves were parting, starting from the base and peeling all the way out to the tip. While the skin remained bare for the moment, itching was a sign it would erupt with the same silvery blue fur. As his newly formed tail parted from either side, leaving him with two more partial growths, Corey felt his elation rise. He didn’t have to wait for an additional splitting to know he was likely on his way to turning into an Alolan Ninetails, by far his favorite Pokemon!
With three fully formed ones now, each tail started to ache from either side, as though preparing to add two more of their own. It was rather pleasant to feel the skin parting from the base, splitting down to the bones and allowing each eventual tail its form It seemed all nine of them were connected at the base, and could not entirely more independently. Not that he cared, excited to feel how heavy they were, especially as they became covered with silvery blue fur, erupting into curls at the ends of each. Against his fear over the changes and what they might entail, Corey couldn’t help but twitch the lot of them, rubbing them with reverence and thankful for the experience of possessing them!
Tina, meanwhile, was still delighting in her body, more white fur growing over her skin and muscle spreading underneath. Corey couldn’t help but feel a flush of arousal from the prospect, as much as he couldn’t imagine such making him horny. Still, he was eager to kiss his girlfriend, having to stand on tiptoes now that she was taller than him. It was a little strange, especially as her lips warmed and started to expand. Still, the touch of his lover sent a shiver through his being, tenting in his pants and making him wish to alleviate it before the night was over!
It was somewhat delightful to tell Tina’s skin was hot, though not fiery as her Pokemon type might have indicated. That was for the best, Corey not wanting to melt as he changed! It was still her familiar presence, though as she pulled back, grin on her face, it was clear what part would change next. Soft cracks spread from her cheeks as her lips expanded, fattening as she pulled them back, exposing thicker, pearly white incisors. Though the visage was rather daunting, Tina was all smiles as her face pushed further outward, taking on a more equine appearance. As much as he might not have expected it, Tina was turning out hot as hell!
Eagerly, Tina reached down to tease her lover’s bulge, leaving Corey to moan out from the familiar pleasure. He was already leaking a little, and he was just as happy to reach up and touch her breasts through her shirt, the two of them getting into things. It was not enough for him to ignore the itching playing over his back, what he had to assume was his own spreading silvery blue fur. As though reading his mind, Tina was eager to reach down and help him pull his shirt up so he could see its growth in the full-length mirror. The prickling was irritating, to be sure, but it was still pleasant to feel the cool fur spreading over his back and even starting to touch his chest. Reaching out to feel Tina’s fur, the contrast was rather pleasant, hers warm to his cool. While they retained some semblance of the Pokemon types they were growing into, the more real-world application was welcome, if still jarring nonetheless!
It was getting more and more obvious that Tina would be the taller of the two of them, especially as she reached down and pulled her socks off. They were in time to see her heels stretch, Tina balancing herself against the bedpost as they did so. Her heels were becoming oddly long and thin even as her thighs and calves swelled with muscle. Strangest of all was how her middle toes started to extend, thick nails encroaching over them as she forced herself to adjust her stance. It seemed her middle digits were gradually swelling beyond what her feet could comfortably obtain. The shape soon began making sense as the rest of her toes started to twitch before shrinking, leaving room for her middle toes to take over.
Corey was there to help her stand as well, though it was a struggle for him to do so with how heavy she had gotten. Both did their best to watch as the rest of Tina’s toes pulled inward, leaving both feet ending with those thickening middle toes. The implication was not lost that perhaps they would become fully hooves, though it seemed the changing contours of her legs would at least make it possible for her to walk. It was amazing her heels were so long, her calves compact and muscular. As the balls of her feet shrank and her massive hooves took shape, Tina found herself able to stand, taking her hand off her boyfriend and the bed as well. She was even eager to lift up one of her hooves to show off, the depression within the center rather detailed as keratin continued to surround it.
A bump on the ceiling left both to look up, as Tina’s horn made a mark in the paint. “I hope that doesn’t come out of the deposit,” she giggled, and Corey let himself relax and chuckle as well. It was wonderful having her calming presence with him under an otherwise terrifying experience. And allowed him to relax into the changes as well, feeling a tingling in his own feet that was a sign of further change.
Automatically rising on his own heels, Corey looked down in time to see his toes retracting, shifting his stance as he lost his former balance. He was quick to shuck off his pants as well, wanting to see the steady itching of fur over his legs and hating the feeling of it growing against the fabric. His legs weren’t as muscled as his lover’s, but it did seem his calves were shifting in much the same way as Tina’s had gone. His heels more than made up the length, and he was more easily able to rise up on the balls of his feet, feeling a little like a dancer as he did so. The tingling in his toes took priority, however, especially as his large toes started to shrink at a much faster pace. Corey could feel them being pulled upward as they continued to diminish, as though being absorbed into the bone of his feet. Attempts to move them were for naught, though Corey could hardly bring himself to care at the moment.
The mobility in the rest of his toes was soon to wane as well, pops ringing in their ears as the joints gave way and the bones compressed. Already short to begin with, it wasn’t such a daunting prospect to experience them changing, nor to feel the skin between them thicken somewhat. It was a challenge balancing on the balls of his feet, though Tina’s strong arms were there to help him, and Corey felt their bottoms widening even as his immobile toes took their proper shape. A tingling along the tips of each and his feet as well made him want to raise them, and he was rather pleased to see canine pads forming, a darker blue that accented his fur rather well. To complete the look, Corey could feel his nails thickening, wrapping around the tips, and forming blunt claws that clicked against the floor. Tina joined him in his delight, stomping her new hooves and whickering in a voice much deeper than she was used to. Corey delighted in dancing on them, smaller than his human feet and leaving him lithe and agile.
Looking at the mirror, it was obvious to Corey he was a little taller than his previous 5 ‘8, likely in leg length. He was a far cry from his girlfriend, however, though could not bring himself to care. Something about her massive, muscled body really did it for him, and as she reached down to grope his crotch once more, Corey could only let out a moan, excited about where the night would take them.
Still, it seemed both were eager to allow the changes to conclude before getting down to any fun. The tingling in his scalp made him turn back to the mirror, his shoulder-length hair lengthening as it spread down his neck. Corey was tempted to rub at it, though was enamored by watching the spread of silvery hair moving from the roots to the tips and the ends fluffing out into a series of lovely curls. It played down over his shoulders, bouncing a little as he danced around, surprised by how much lighter he was. To top off the look, the color of his left bang darkened beyond the silvery shade that made up the rest of his hair. Its brilliant blue was a stark contrast with his Ninetails coat, and Corey couldn’t help but reach up and brush it a little, having appeared as though he’d willed it as part of the changes.
The more he regarded his visage, the more the feminine quality of his body seemed to appeal to him. While he could perceive his muscles firming out, giving him a lean, athletic body, it was a far cry from the mountain of muscle that Tina now possessed. It was the opposite of their former dynamic, though Corey couldn’t find any fault with that, wanting to rub up against her and feel the warmth of her body. And he did so, loving the sensation of short equine fur coating her all over, while she rubbed at the silky silvery blue fur that spared across his own skin. Having a massive, muscled mate was more of a turn-on than Corey had expected, and it was only to get better as the changes took over!
Yet, Corey was left perplexed as Tina continued to swell with muscle, her belly taut and arms expanding as she flexed them with curiosity. Her breasts, while having enlarged somewhat to match her stature, were beginning to flatten, the fat and tissue dissolving as though fuel for the further muscle mass. Tina went to rub at them with more curiosity than fear, confusion crossing her features as their sensitivity declined. With their contours being pulled taut across her chest, what remained of her assets were reduced to muscled pecs, masculine in configuration but somehow more arousing to Corey than he might have expected.
Looking down at his girlfriend’s crotch, it appeared she was of one mind, seemingly wet and smelling of her need. Yet, something soon stirred within the folds of her clit, as though the tiny pearl was swelling against the skin of its casing. The effect had her moaning out with a decidedly masculine voice, something she seemed to delight in. But it was happening too fast, swelling on her loins as her damp groin hair spread out into its own white coat of fur. At about an inch now, the skin-shaded flesh soon began to darken, pushing away at the folds and expanding to envelope what remained of her slit. Rather than be afraid, Tina was eager to explore its heft, wrapping her fingers gingerly around it. Her touch seemed to send a surge of growth through the thing, and despite the confusion on her features, it seemed Tina harbored a bit of excitement as well.
Moaning a little, Tina continued to rub her groin as though trying to alleviate something happening within. Corey could only watch in stunned silence, not sure what was happening but needing to see it through to conclusion. It seemed that her opening was quivering against her will, though not from penetration but rather from something preparing to push its way from the inside. The dark, wrinkled flesh that emerged looked like nothing either had seen, and Corey felt himself shiver, as though she was giving birth to some unknown horror. It took him some time to recognize the ovular outline as something seemed to fall within the flesh, dropping it further from her sex. It wasn’t until a second orb descended that the shape of the thing seemed to make sense. As the remainder of her vagina closed around it, Corey could not deny she possessed what appeared to be a very generous ball sack swollen with virile testicles. And that meant the thing she was holding onto with reverence could only be…
Not afraid of her Pokemon penis, Tina continued to stroke as it grew, causing her to strain her fingers to keep them around it. It was larger than Corey’s own already, better matching her new stature. Corey could hardly bring himself to be jealous, however, rather feeling mesmerized by the sight. It was clearly inhuman already, its skin black as extra folds of flesh began to bunch up around the base. Tina’s cock seemed to be propped up somewhat by her developing sheath, though it was hardly a deterrent for masturbation. She was giddy to jerk herself off, the tip even leaking as her sheath became coated with white fur and her cock continued to grow. The shape was rather odd, a ring of flesh forming in the middle that she seemed eager to stroke. The tip was flatter than a human’s cock, looking more like a mushroom head surrounded by a crown of nubs as the massive piss slit leaked copious fluid. It was bizarre, like no penis he had ever seen. But judging by the way Tina kept rubbing herself, she was clearly into it!
All Corey could do was stare in stunned silence, unable to believe what he was witnessing. It was bizarre to think he would be more shocked at his girlfriend having a cock than turning into an anthropomorphic Rapidash. Yet, his own cock was erect, despite any preconceived notions of his own sexual identity. He couldn’t help but be aroused, not only by the sight of her maleness but by how much Tina seemed to revel in it. Corey had no idea why she was becoming male, or why the changes were so erotic. But in the moment of absolute rapture, it was all he could do to wait and see where the changes would take them!
As though the thoughts were a catalyst to his own transformation, Corey felt a sudden tension in his balls that he couldn’t control. Moaning, he barely had time to reach down and rub at it before his cock unloaded and his underwear was filled with his cum. As embarrassing as it was, Corey could do little to stem the release as he shot load after load into his briefs. Even when he figured he had gone well beyond his usual ability, it seemed his cock had more to give. It was all he had to remain standing there, as though his entire testicular load was being spilled in one go. And Tina’s horsey nose was quick to flare, her lips pulling back a little as though she was enjoying the scent of it.
Eventually, Corey felt he was done, and pulled down his underwear, both of them hit with a pungent whiff of semen. It was annoying to have so much cum soaked into his groin hair, especially as the hairs shifted to match the silky coat over much of his body. A part of him wanted to go to wash it out, but the sensations welling from his groin had not quite abated. Strangers was how something under his cock began pulling back toward his ball sack. Corey was curious to rub at it, the consistency of the fluids against his human hands leaving him eager for more. His testicles were deflated by this point, having expended their load and preparing to repurpose themself. As the skin around his sack opened up, Corey’s curious fingers traced over the hole, finding it went deeper than he had expected. Only the jarring sensation of his testicles being pulled within him was enough for him to take stock of what was happening. Still, there was nothing he could do as what became of his sex continued widening, altering its purpose toward something decidedly un-masculine.
It was then that the implication of the changes hit him in full force. Corey let out a moan, more feminine than he was expecting as his dripping fingers pulled away from what looked too much like a vagina for his comfort. Just as Tina had swapped sexes, it seemed the same was happening to him. A part of him wondered if they had perhaps taken the wrong pills, though the fact he was turning into his favorite Pokemon left him to think that was unlikely. Still, as his opening continued to expand and his new cunt lips leaked their lust, Corey could hardly find fault in the change. It was bizarre that his cock was still present, still semi-erect at the apex of what had to be a vagina. Rubbing the sensitive virgin flesh felt amazing, though as he pulled his hands away, a certain sensation of emptiness encompassed him. Almost as though he was in heat, and needed something to quell it…
No sooner had those thoughts crossed his mind than the feeling of a massive, thick leaking organ rubbing him from behind caused him to gasp out. Corey barely had to look down to see the black cock head of his lover teasing toward his newly-developed folds. He hadn’t realized it, but his nine tails had reflexively lifted to allow her access, and the heat of her body was soon pressing against him, rubbing him sensually. Sitting just under his own modest human cock, Corey found he was not emasculated by the size of Tina’s horse meat. All he could do was to stay still, allowing Tina her exploration and feeling eager for what would come!
Corey was barely able to repress a cry as Tina moved to rub his chest, pulling him close as she rubbed her cock against his newly formed cunt lips. As though her touch was a catalyst, the tissue underneath his nipples began to swell, expanding as she played with his areolas. They were far more sensitive than he was expecting, and Corey could only raise his hands to guide Tina’s fingers over them, having her tease where Corey was able to perceive the most pleasurable spots. They felt amazing, swollen and busty, and far larger than Tina’s own had ever been. As her hands continued to play over Corey’s new assets, he couldn’t help but revel in the electrical tingles playing all the way down to his loins. The intense sensations were almost enough to make him cum on their own, Corey was blind to the sensitivity of such breasts and eager for what they could grant him!
Even through the mind-blowing pleasure of his changing sex, Corey was able to perceive his girlfriend’s fingers altering, the digits firmer than he was used to. Her new touch wasn’t unpleasant, and Corey was eager to trace his fingers over them, feeling their nails moving to encase the entire surface of each. Unlike her feet, the nails only covered the tips, while her digits retained their dexterity. To complete the change, the skin of her hands and palms was steadily covered with white equine fur. With her massive, muscled chest and taller stature, it seemed her changes were done, and Corey couldn’t help but shiver in lust. It was not just his lover teasing him, but this massive, muscled stud of a man. And especially the cock that hung from her groin, waiting to plunge into Corey’s new depths!
Gingerly teasing both his breasts and Tina’s hoof hands in tandem, Corey was becoming aware his own fingers were changing, shrinking only slightly in contrast to the paws on his feet. His nails thickened, turning the same blue as his toenails, longer though relatively blunt. Similarly, blue pads started to form on the skin of his fingertips and his palms, and Corey lamented the lack of tactile ability they seemed to possess now. Yet, that trepidation was short-lived as their firm grip played over his assets, those electrical charges intensifying as his orgasm started to build. They were far more adept at teasing the skin, his bare areolas made of firmer stuff even as his new breasts became coated with fur. In the moment of heat and passion, Corey could hardly care, reveling in his form and eager for the release that his body craved.
As excited as he was to explore his body, it seemed that Tina was getting impatient. The sensation of a leaking cock head rubbing against his moist cunt lips made him shiver as two powerful arms grabbed his shoulders, holding him in place. The stimulation to his open cunt lips was almost more than he could bear, and Corey gasped out in his new feminine voice as Tina forced her way in. Such a thing should have been far too large for him, but the turgidity of Tina’s erection managed to part his lips, working its way inside. It was all Corey had to keep standing there, quivering as his new insides were opened for the first time.
Yet, he soon found out his lover’s member was designed for something much larger, and Corey was left to groan as Tina made her way to his vagina beyond. It seemed like such a member would split him open, and as Tina worked more horse cock within his cunt, Corey could perceive a slight bump in his belly. Thankfully his new anatomy was able to take it without pain, and Corey was left to revel in the sensations, Tina’s cock teasing his insides all at once. In particular, his semi-erect penis was still grinding over Tina’s girth, almost enough to send him into an orgasm on its own. Her mammoth horse meat continued to flare within him, making his minute cock leak as it shrank. Regardless of how small it grew, however, the sensitivity did not wane and perhaps continued to increase with each passing moment. He had to think the remaining flesh was being repurposed to a clitoris, much like he’d seen Tina’s become the foundation of her horse cock. Being fucked into female form went beyond any pleasure he might have expected, the veins and ridges over her cock hitting him in all the right places. As his former cock head reduced itself toward a minute nub, Corey felt his entire body going into an orgasm, making him call out his lust!
“Oh, yeah, baby, cum for me!” Tina whispered huskily in Corey’s ear, making him squirm. The fact his ears seemed to stretch as Tina tongued them was powerfully erotic as well. He wanted to reach for them, though was currently occupied by rubbing his breasts as Tina held him, gently thrusting all the while. Corey could only relish the orgasm, feeling his clit being massaged and extending his pleasure beyond anything he had known. Given the increasing level of stimulation Tina was giving him, Corey was sure it was only the tip of the iceberg!
Looking in the mirror, Corey was a little surprised to see his eyes starting to shift toward a pleasant aquamarine, wide and eager as he was fucked into form. Like the Ninetails he was becoming, the shade took up the whites of his eyes, giving him a pair of black slits that opened to take in light from the room. The visage was rather pleasing, though he lamented the lack of a muzzle that Tina seemed to relish as she fucked him from behind. Soon, however, a cool tingling began to play over his lower jaw as it expanded outward. His face seemed a little smaller than he was used to, though it seemed to work well as his nose was drawn toward the tip. The skin around his lips slowly turned blue, as though he had gone cold, though it felt natural as he pulled them back slightly. The sight of his teeth sharpening was rather pleasant, accentuating his features rather aptly. His tongue, too, was getting longer, thinning as he worked it over his lips. A thought played over his mind, that such a muzzle would be effective for sucking the horse cock his lover possessed. It would be fun to try, though after he received the vaginal fucking he longed for more than anything!
As his nose turned blue and slits slid up the sides, the scents of the room burned into his being, sending a shiver of arousal through his loins. Corey had been barely aware of it, but his senses had been heightening all the while, his hearing able to detect his lover’s heartbeat and the steady grunts as she fucked him. The slick sounds of her horse cock within him resounded in his ears, and it was all he could do to resist the urge to let himself fall over the edge and cum. The scent of her body was something else as well, Corey breathing in her heady musk and allowing it to fill his being. She was a powerful, virile stallion, with a cock to match, and Corey felt honored to be taking such a beast. He belonged to her now, wanting to do everything to pleasure her, as much as her massive cock was giving him everything he wanted and more. In some ways, this expression of his sexuality was better, giving him a greater sense of purpose as he leaned back against his equine lover and willed her to take him as she would.
Even the size of her dick within his cunt lips was not enough of a deterrent for Corey’s desire. “Fuck me… please…I need it…cum in me!” He called out, reaching down to rub at the bulge in his belly where her flared horse cock sat. In response, Tina did her best to thrust gently, holding him firm in her powerful grip as her cock throbbed intently. Even with his former penis reduced to a clit, the surface of her ridged horse cock was able to send direct waves of stimulation through Corey’s new genitals. In tandem with the vaginal penetration and teasing of his ample breasts, there was little in the way of his ability to hold back. Corey needed it in the worst way, the pleasure building all through his body instead of simply centered on his sex. It was akin to a tidal wave rushing toward the beach, slapping against his sex before crashing with a force that his formerly male body had never known. And in the moment of anticipation, Corey could no longer hold back, allowing himself to fall into waves of bliss.
“I’m going to cum my love…AAAAHHHHH!” Corey called out as his orgasm struck him from three sources at once, cascading over his body as it shook. He was somewhat aware of the grip his vaginal walls had on the horse cock within him, and the sensation of firm hands holding him in place as he experienced a mind-shattering release. His new body was able to hold firm, though there was little in the way of preventing Corey from experiencing all it had to give.
It seemed his orgasm was enough to trigger his love as well, Corey almost willing his cunt lips to milk the stallion cock within him. She was throbbing wildly now, and it was an impressive effort for her to hold back as long as she had. It seemed after confirming her smaller mate had his pleasure, Tina was ready for her own. And Corey wanted nothing more than to take it, feeling her balls slapping against his underside as they prepared to blow her burden. As much as he figured he had been prepared for it, the pleasure of Tina’s wild thrusts was more than enough to extend his own release. Corey was filled with maddening desire for the pulsating cock head within him, and the rush of semen that burst through his vulva toward his uterus. So much sticky fluid was ejaculated within him that Corey could feel it pooling within his sex before being pushed out with a series of squelches. It seemed his stallion had testicles full of sperm, and her burden was enough to leak out of his abused cunt before Tina pulled out, cock still bobbing there and covered with their combined fluids.
Corey was left to brace himself against her, cum leaking from his slit and sex still clenching from the sensation of the horse cock that had taken him. It had been the most amazing sexual experience of his life, made all the better that it was with the love of his life. Tina seemed to share the sentiment, reaching down with her muzzle and kissing Corey’s own as the two of them basked in the afterglow. The scent of sex was far more potent to their changed senses, and it spoke of their love for each other, both finding it surprisingly pleasant. Even as she moved to kiss him, Corey was aware her eyes were now a handsome brown, equine rectangles that suited her new form well. And all he could do was relish the feelings of their lovemaking and wait for her to rest until she was ready to breed him again!
“How was that, honey?” Tina asked, concerned for his pleasure. Corey could only nod, still awash in his new hormones. Eventually, he was able to say, “I want to go get cleaned up, but keep that cock hard for me!” As an added incentive, he moved to lick the tip of her semi-erect member, sending a shiver through his stallion. It certainly felt right to do in the moment!
Smiling, Corey headed to the bathroom, careful of his tails as he closed the door. In truth, he would have been happy to have his horsey lover explore his breasts more, and maybe partake in a second round of love-making. But there was something about the novelty of having feminine features that he wanted to explore for himself, and the bathroom mirror was sufficient for such a task. His assets were rather generous, surpassing Tina’s former ones, and the pleasure from teasing them sent delightful electrical tingles through his body. The weight of them felt natural in a way that surpassed his understanding, and he had to wonder if the swap in genders was deliberate. Not that he wanted to stay female, thinking the pills were supposed to wear off by tomorrow. But it was certainly a wonderful experience, one he would cherish and learn from as they went back to their old human bodies.
Moving to rub his sensitive sex, Corey couldn’t help but grin, thankful for the experience and proud to still be leaking his lover’s cum, impressed by the load. As much as the scent did it for him, he figured he should clean it from his fur before they went back to their lovemaking in earnest. Surely, her stallion-sized stamina would be enough to take him again, and the feeling of being filled with her horse cock and cum was more than Corey could have imagined. Yet, a sudden pressure in his abdomen gave him pause, and he leaned over a little, trying to alleviate it. A part of him worried he had injured himself taking her stallion’s cock, but the pressure was deeper inside him than even such an impressive penis could reach. And it was happening rapidly, not the gradual ache that might have come with such an injury.
All he could think to do was rub at his stomach and loins at the same time, attempting to alleviate the pressure for only a moment as it grew rapidly. To his surprise, it felt oddly sensual, though it was not a sensation he could easily understand. It was at least stimulating to have something swelling within, playing through his tubes and opening up toward his uterus. Corey felt it was akin to being overly full, though lower down, and swelling to the point Corey felt himself reflexively pushing, needing to sit down from the pressure.
Even as he fingered his leaking sex, Corey could feel his cunt pulsating in and out, as though flexing its muscles in an attempt to prepare for what was to come. The pressure within was building at a rapid pace, enough to make him whine out in a more vulpine cadence. The source of the pressure escaped his awareness, though it was far too intense for him to avoid. And as his insides were opened against his will, all Corey could do was spread his legs wide, fingering his clit as best he could from the angle.
As something began to crown the inner walls of his vagina, Corey was briefly reminded of Tina’s changes before her testicles had descended. Yet, this force was far larger, off-white though it was somewhat difficult to perceive through the leaking fluids. That was for the best, his sex moist and dripping to allow whatever was within safe passage. Its firmness was dwarfed only by its size as it continued to open him beyond what he thought was possible. And as the force of it rubbed against every inch of her insides at once, Corey was surprised to experience a semblance of an orgasm. It was unlikely such a process would normally elicit such a response, probably a facet of the change itself. But there was no denying his pleasure as a massive, ovular object crowned the tip and started to slide out, slick with fluids and making him call out in pain and ecstasy all at once.
Stunned as he was from the release, Corey was shocked to look down at the sight of what could only be an egg. Gradually, it moved past the center before being squeezed all the way out. It was impossible something so large could have formed within him, much less work its way from his elastic vaginal walls. He knew he was female now but…the idea of laying an egg went far beyond anything he had been expecting. Sure, Pokemon laid eggs in the lore but…to think that not only would an anthro facsimile be able to do so, but in under an hour after sex was more than he could bear!
And that was just the beginning. He wanted to call out to Tina, to get her to come in and help. But he wasn’t sure how she would respond to the fact he had laid an egg. Or, perhaps worse than that, the building of pressure in his loins was such that he surely wasn’t done. While the pleasure was somewhat familiar now, it still made him keel over, spreading his legs and rubbing his sex in encouragement to have it exit comfortably. His cunt was oozing pungent fluids all the while, while different than his arousal, it seemed to relax his body enough that he was able to push without struggle. Soon, the second egg had moved to crown his sex, and Corey let out a yip as his elastic cunt lips once more opened to allow it to be expelled. It soon moved to sit with its sibling, leaking drying fluids as it did so. And, given the tension welling deep within his ovaries, they were not to be the last…

“So, how have you been coping with your change in roles?” Their therapist asked, taking out her iPad to make some notes. While it was normally something the pair didn’t concern themselves with, given their current circumstance, they were both unable to keep their eyes off her actions. After all, despite her perceived ignorance about the after-effects of the pills, it was impossible to deny the coincidence was too convenient. Still, they both allowed her the benefit of the doubt while she held the keys to their eventual reversion. As much as their new hormones dictated otherwise…
While they had been assured the changes would reverse within twelve hours of taking the pills, it seemed that promise had been only half right. Corey had to admit, there were some advantages in keeping facets of his Ninetails body, and in another world, another life, he might welcome the permanent nature of such a change. His feet and paws, in particular, did not require he ever wear shoes, something that he found far more convenient. His hair, too, was far more luscious and vibrant, and the blue streak he had come to adore was part of his form now. Hell, had he changed back fully, he might have dyed it that way himself! His nails, too, were rather fetching in their vulpine state, longer and thick and blunted, adorning his fingers and toes. While he couldn’t hide them, his vulpine ears were greatly appreciated, loving the level of auditory influence they were able to provide him. And while they were significantly smaller than they had been, he still maintained some semblance of breasts, something he preferred to possess in some form.
Speaking of assets he couldn’t hide, Corey was almost disappointed by how unwieldy his nine tails turned out to be. Possessing them was a dream come true, and the weight of them on his spine was something he hadn’t known he was missing but couldn’t imagine himself without now. Yet, so little of modern human life was kind to possessing a single tail, let alone all nine fluffy appendages that Corey owned. Pants couldn’t contain them, and he was forced to lower his clothing to allow them room. Sitting comfortably in the car was a challenge, and more than once, much to his agony, he’d gotten them stuck in the door! It left him rather conflicted about his hybrid state, sad it wasn’t something he could show the rest of the world but eager for the joy it gave him when looking in the mirror. It was perhaps bizarre to remain in a hybrid state as he was, his fur removed, his face human and his lovely aquamarine eyes returned to their former shade. A part of him wanted to return to his fully Ninetails form, as much as it would be a detriment to his chances of being a human again. But so long as Tina remained his Rapidash…
Tina, too, carried several of her Rapidash attributes even after the changes were supposed to have reversed. Like Corey, she still possessed her new hooves, rather unwieldy but something she had come to get used to. Her fiery tail, too, was present, though it was easier for her to hide under her pants, even though it pained her quite a bit to do so. While she still possessed a mostly human form, the muscled, athletic bodybuilder’s physique was a part of her now, something Corey was happy to lean into. Her chest had remained flat and muscled, looking more male than anything previous. And while her hair had largely returned to its former human consistency, the fiery orange and yellow highlights seemed to be a permanent addition, something she did not wish to hide away.
Of course, there was one other aspect that had not changed back the morning after their unexpected sex and more unexpected pregnancy. As much as Corey had loved the feeling of having a cunt, even after laying three eggs, waking up in his lover’s embrace feeling moist and wet down there was more than he could bear. In his moment of heat that first morning, he had not realized how many of the changes were still a part of him. The only thing that mattered was the ache in his cunt, and the assurance that his touch could seek the throbbing stallion cock his lover possessed that would allow him to ease it!
“I’m glad to hear had a positive effect on your intimacy,” their therapist had remarked, and as concerned about their hybrid forms as they both were, there was no denying the truth in that. Having been through such an ordeal, it was obvious the pair would love each other no matter what, regardless of their form and genitals. But Corey seemed to possess a more submissive quality that seemed to pair well with the confidence his muscled love showed off. Their sex was significantly enhanced to the point Corey wasn’t sure he would want to turn back if he could.
There were still many questions they had left unanswered, things their therapist surely knew but was less than forthcoming with. How she had developed pills that could change them into Pokemon personas was beyond them, as much as she seemed to have employed the practice on others before. But as much as she assured them, the fact they didn’t change back all the way was a mystery. She was still exploring options for the pair of them, having hoped they were revet on their own. As the days passed, however, that seemed less and less likely. The pregnancy might have been a key factor, as most forms were not able to propagate within a single night. Thankfully, her sessions were free until they were able to find a way to revert to their humanity! And there was much work the pair were thankful to have her help with. Not only their change in sex but also the fact they had unknowingly become parents in the course of a single night!
Yet, as the two of them headed home, Tina carefully driving with her new hooves, Corey couldn’t help but reflect on this new stage of their lives together with some anticipation. The eggs the pair had laid, while virile, wouldn’t hatch for several years. The species of their offspring was a question even their therapist didn’t have a satisfactory answer for. But it wasn’t something they had to worry about for some time and something that wouldn’t happen again, as best as they’d been told. And that was something Tina’s body relished as the two of them made their way into the bedroom as soon as they got through their door. The sight of her persistent arousal was something Corey had come to cherish in the past few weeks as they had gotten used to their new roles and genitals. Thankfully, along with her equine changes, Tina’s sex drive hadn’t been limited in the slightest. And the telltale bulge under her dress was all Corey needed to know she was ready for some fun after their therapy session…
