So You’ve Been Transmogrified:

Horsey House Party Part 10


Tracy was standing under one of the vents on the ground floor of the house. She had stopped drinking an hour before and was now just waiting around for her friends to tire themselves out and leave. That however was proving to be a bit more of a challenge then she had thought. All of them were still drinking. And more then that all of them were getting unbearably horny. She had to bite her lip as one of her friends, a tall blond, hung her arm around her talking about all her boyfriends.

College had been good to Tracy. Life experience, friends, even a little bit of romance, the last one however had petered out after only a month. Not for lack of trying however, even though it was her that had broken it off with him. The whole time something had been wrong, something that she hadn’t been able to put to words really, much to her ex’s and her own frustration. From there it had been a long series of questions that had led to her drunkenly asking one of her friends if she wanted to make out. That had led to a long and wonderful night that once morning and sobriety hit left her wanting for more. Still though even after all that, and a few more nights of fun she was still not feeling like it was what she really wanted.

Even now it was a nagging voice in the back of her head. She knew that she liked girls. Even some of her friends knew. Just hearing them talk about their interludes with their boyfriends was getting her a bit worked up. Her mind wandering to how the men touched the women, gripped their bodies and how they made the grills feel. She sighed feeling hot. Looking up she could feel the warm air of the vent blowing down onto her.

“I mean fuck he was huge. Like hung like a horse huge.” Her blond friend said.

Tracy felt her legs twitch clenching a bit as the mental image hit her full force. The blond being taken and fucked senseless by some nebulous man, his warm cock buried in her tight welcoming pussy. It was a thought and an image that burned itself into her mind in such a way that she couldn’t dispel it. She felt her body heating up in equal parts from the warm air blowing down on her and from the lustful thoughts floating around in her head. She shook her head feeling confused and flustered and a million other things as her face turned red.

“Hey you good Tracy.” Her blond friend asked taking her arm off of her.

“Yeah yeah, just need some air I think.” she said running her hand down her face as she sighed.

“Relax we’ll be here if you wanna step out for a minute.” One of the girls said.

“Yeah thanks. I'll be back in a minute.” Tracy said walking through the crowd towards the porch.

As she did though she saw and overheard many other parties going all behaving a bit more lewd than normal. Open display of affections and the outright ogling of both men and women alike. A few looks even feeling on her which only served to make her flush a deeper shade of red. Looking to her left she saw a bathroom and ducked in. There was a window there, which she opened. She felt the cold night air hit her and she smiled feeling as some of the heat dissipated from her. Sighing she closed the window and looked in the mirror over the sink.

She was average height, about five foot nine, and had raven black hair, a good complexion, and overall was pretty but not stunning. She sighed keeping a somewhat neutral face as she leaned in holding a hand to her face studying it. She felt off. She had felt off for a long while. Something about the way she felt just didn’t click with her in a way that was so base to her very being that couldn't describe it, not to her friends, not to herself. She had just been ignoring it for a long while, maybe too long she thought sighing as she stood back up.

She rubbed her chin her mind still lingering on the thought of taking her blond friend to bed and fucking her silly. She blinked at the thought smiling a bit. She looked down at her crotch wondering what it felt like to have the other side's equipment. Wondering what it felt like to give, instead of to receive. She looked back up at the mirror looking at herself wondering what she would look like as a man. Bigger maybe, some muscle. She smiled, knowing she would want to be different than she was now. Built like a truck, a true and proper beef cake. Looking back down at her crotch she smiled thinking about what her blond friend had said, hung like a horse.

That would be nice she thought turning around and leaning on the sink as she smiled and let her mind and hands wander. The image of the blond naked sprawled out on a bed making with a wanting look on her face, drawing her in. There was no build no build up, in an instant she was watching and then she was inside her. Full force visceral pounding visualized in her mind. Her body crashing into the blonds over and over. One of Tracy's hands came up to her face, another snaked into her waist band as three fingers hooked up and into herself.

Above her more warm air blew in from another vent. Its warmth brought with it something else. Leaning her head up her eyes closed Tracy felt the warm air running over her. She thought she smelt something, something familiar . She gulped feeling as her body heated up even more. She could feel a burning in herself. A craving for something that she knew now was climax. She moaned imaging herself dumping a huge horse sized load into the blond wondering what the sensations would feel like for real. Pushing into her pulling out of her.

Looking down in the fantasy she caught sight of the equipment she imagined herself to have. Thick, veiny, girthy, blunted? She thought as it was shoved back into the moaning woman. Then all at once everything came to a head. Tensing Tracy held a hand over her mouth muffling her cry of passion as she let out a long sigh and felt the warmth of afterglow rushing over her. She pulled her hand up and out of her pants and smiled. That had felt good, really good.

She took one of her hands smiling and ran it through her hair laughing as she did. She imagined herself with a fucking horse cock. One of her bio textbooks had had a very vivid image of one and Tracy guessed that her subconscious mind had taken the idea of being hung like a horse a bit too literally. With that thought however she looked back down at her crotch a hand still on her face as she pondered the feelings that such a thing could bring with it. She still felt horny as hell, despite having just experienced a climax. Now that she thought about it that had been a very nice climax, great even. She wondered why she was still hungry for more. She looked down running her hand back into her pants as she took in a deep breath. She smelt something there, something musky, something floral. Her mind seemed to push the musky smell aside fixating on the delicate scent. It was pleasant, aromatic, something like a strong perfume. She raised her head taking in a long and appreciative sniff of it.

She smiled licking her lips as she did that. Feeling as the scent only added to her lust. She looked back down at herself, one of her hands was poised to go back in. To pleasure herself once more and she was ready to do it. She wanted to, in a way she felt like she needed to. Then as her eyes watched and she readied her hand she saw something that confused her. In the midst of the rising lust she watched as a bulge began to emerge and tent her pants. In another instant she felt it. Felt as whatever it was rubbed against the fabric. The sudden shock of it almost made her swoon.

She huffed taking in a deep breath as she watched it grow and the feeling grew more and more powerful. After another moment she frantically undid her pants dropping them to the ground. She blinked looking at the absurd sight of a cock pressing against her pants, begging to be free of the garment. She acted quickly dropping her underwear and then looked as she saw four inches of hard cock standing at attention on her crotch. She looked down at it, blinking, unbelieving. Then she cringed as a trembling sensation rolled over her body. She panted gulping as the wave of pleasure hit her like a truck.

She took a few deep breaths and then swallowed taking her hands and feeling around it. She first went to her slit and found a strange feeling. It was there, but not as deep. She could feel two things in it and as another surge of pleasure rolled over her she felt as her old sex closed and pushed out the two things. She looked down unable to see them but feeling them with her hand. Two fleshy orbs the size of golf balls, she gulped knowing what they were and finding the act of touching them strangely pleasant. Then she noticed that her cock was bigger, and maybe getting bigger she thought. It was becoming too much for her to stand. She looked around and then dropped onto the toilet.

She leaned back on it sighing out as she felt the heat and lust of the moment building ever further inside of her. That scent was still their to, floral, fragrant, and as she lingered on it a moment longer she attributed another word to it, feminine. She gulped as the word surged past her mind and seemingly went straight to her cock as it twitched and grew. Both her hands gripped the toilets sides as yet another wave of intense pleasure surged over her body. She gritted her teeth and felt as her whole body tensed and relaxed and finally she sighed out a long breath.

She looked down to see her cock, seemingly done growing for the moment and marveled at it. It was huge. Thick, veiny, girthy, blunted? She looked at the erect thing between her legs and in an instant knew it was a horse cock. She had a fucking horse cock, more then a foot of horse cock she thought. She looked at her balls and was dumbfounded. Softballs, they were as big fucking softballs. They were doing something to, she could feel it, see them moving, churning. Her seed. That produced an interesting train of thought for her.

What good was seed if it wasn't deposited in some place. She was hung like a stud and now, she guessed she needed a mare. She leaned back smiling at the thought and almost laughed at the ridiculous nature of the notion. Her body however seemingly relished the idea. Twitching her legs and making her cock spasm. She whined a bit looking down at her crotch. Her bush was different? She thought confused at the sight of white hair where black should have been.

Her drapes had always matched her curtains but now they were white. In addition to that the hair was different, less curly, shorter. She ran a hand over it blinked. She thought it felt like, fur? Then she saw it start to crop up around other parts of her crotch. White at first and then black towards her hips. Patches at first but then it started to grow thicker and supplanted her skin. The white hair, she winced as her mind thought of it like that. She shook her head and then looked back down, fur it was fucking fur. She gulped watching as the white stuff grew down the inside of her legs and over her balls. The black fur was also growing and started to just that over her thighs and up her back and sides.

She sighed out feeling as it grew over her and then blinked as she felt something else growing. She turned around blinking and watching in disbelief as a tail began to grow out from her back. Black fur surged up it as it grew. Long strands of hair growing down it along with some white fur grew interspersed with it as well. Then wincing again Tracy took both her hands gripped the toilet as another wave of pleasure rolled over her changing body.

She panted as she felt the changes to her form becoming more and more drastic. Her form grew in size. She could feel the places where the fur covered her further charging. Muscles were growing, parts of her body were getting bigger and stronger. Looking down at her crotch she could see muscles growing on her thighs and legs and her and balls growing a bit more as well. She sighed feeling her rear tighten as he gets turned to buns of steel. Despite everything and the weirdness of it all she couldn't deny that it all felt so good, and on top of that it felt right.

Something about the way she was feeling felt good at a baser level. Like something in her head clicking into place. She looked down at herself again to see the fur spreading up under her shirt. She sighed out wondering what was going on there. She took a deep breath and pulled her shirt off. Taking it off and gazing at her form she was awestruck. She was chiseled. A six pack highlighted by the spreading white fur and contrasted by the raven black fur shooting up her sides. She watched as the fur neared her breasts and wondered what would happen to them.

She watched feeling as the tissue there changed and morphed as fur ran over it. The white fur covered them as they seemingly melted back into her chest. The flesh there spreading out and filling in her new upper body. Her developing physique took another turn as what was left of her two breasts hardened turning to muscle as a pair of rock hard pecs formed on her front.

From there the black fur spread over her shoulders and up the back of her neck and down her arms. She could feel new muscles there as well and took one of them out stretching it to watch as the black fur ran down it. Around her elbows the fur suddenly changed back to white and continued down her arms to her hands which grew thicker as they were covered. Her fingers swelled to the size of sausages as her nails grew thick covering her fingertips in a thick whitish caps.

The white fur on her front surged up then and she could feel a pressure building in her skull. She wanted to see what would happen to herself, and was curious as to how she looked. She stood up falling for as she did but catching herself on the far wall. She looked down seeing her pants caught around her ankles. She kicked her shoes off and stepped out of them noticing her swelling legs. Black fur covering the outside and the white fur coating her inner thighs and calves. Turning around she leaned over the sink watching as the fur surged up her body.

Her neck started lengthen stretching and growing as it thickened with muscles. She turned her head to side watching as the black fur surged up the back of her head over running her ear which started to move up her head. She then watched amazed as the black fur mingled with her hair which then turned white. In a sweeping change all of her black hair was turned white growing longer as it changed. The black fur seemed to take toot under her hairline growing under it. She looked to her ears again now at the top of her head and pointed. Black fur covered them as they stood through her lengthening white mane.

Finally her mind rested on the pressure in her face which reached a boiling point. She winced leaning down hard on the sink. A moment later she looked up seeing as black fur grew down from her scalp over the bridge of her nose and white fur grew in from all sides. Then watching in disbelief as she saw her face grow outward. Pushing into a muzzle. She felt a compulsion to close her eyes as the white grew over them. She looked down wincing hard as she heard bone cracking, felt it cracking, felt the pressure of her skull pushing out, felt the tingling as skin was overgrown by fur. Then nothing.

She was looking down at the sink, her grip on the thing iron tight. She was breathing heavily. After a moment she looked up. She saw her face, only it wasn't her face. She gulped leaning in and looking at the equine visage before her. She was a hunk, muscle bound hung like a, well a horse. She gulped and just looked at herself. A distant memory of meme formats as the Fabio of horses rung in her head and she figured she now fit the bill. Her muzzle was topped by the black fur and the rest of her face was snow white. As was her hair which she saw had grown down to her rear. The hair dangling from her tail was to her knees. She gulped admiring her new form and felt a plethora of things that she boiled down to immense self satisfaction.

She gulped , taking a hand and holding her still hard cock as she looked at her profile from the side in the mirror. She was huge in every sense of the word, the monster between her hips had to be more than a foot long. Then again looking down she had to be at least seven feet tall. Looking down to her still changing legs and taking everything in her through that her body while huge was at least well proportioned. Then looking up at her muzzle something in her finally kicked into motion. She was a fucking horse, a male horse.

There was banging at the door. She blinked looking down at herself. She could not be seen like this. She didn’t want to be seen like this. She was a freak, she was weird she was… She shook her head looking to the window and opened but looking out it she realized that her current build prevented that. She also looked down and saw the ground a good ten feet under her. Gulping she heard the bagging on the door again.

“COME ON I NEED TO GET IN THERE.” the person on the other side of the door, a man seemed desperate to get into the room.

Tracy gave her issue another moment of thought and decided to make a break for the deck. She could get out into the yard from there and at that point well. At least she had options. Like what? Run home stark naked in the middle of the night after having turned into a hunky horse man. She sighed, not sure what to do. The banging on the door turned more and more frantic.

Finally unable to think straight Tracy turned and opened the door and loomed over a tiny man who looked up at the larger stud trembling. Thinking fast Tracy looked towards the back door seeing an opening and then back down to the man.

“You saw nothing!” she said pointing at him and glaring at him as she darted past him.

She didn’t look behind herself and just made for the door. Moving though the room she was taken back by just how little everyone seemed to care. Their gazes lost in other things, other bodies, some of them kissing, some of them doing other lewder things in full display of others who just watched. Not stopping Tracy simply made for the door.

Opening it and then closing it feeling as the cool night air hit her naked body. A chill ran down her spin. She looked around, not a person in sight. She sighed and then looked over hearing a few giggles. She blinked seeing the hot tub full of equines. One big shiny rubbery looking stud being pleasured by two rubbery mares. There naked bodies glistening in the light. Something else in Tracy's mind slotted into place as she became frozen watching as two other mares waited sitting on the rim of the tub to have a turn at the stud. Their bodies were still wet, glistening and remaining in the night. Their giggling intoxicating as Tracy found it harder to think about anything other than the mares to her side. The stud smiled and then looked over seeing the fellow stallion standing there watching wantonly for the mares.

He raised a hand pointing at the two mares eagerly waiting there turn with the rubber stud. “How about you two go have some fun with him, he looks like he could use it.” he said his voice loud enough for Tracy to hear.

Tracy blinked watching as the two mare turned around and got out of the tube. Their bodies were comically sexual. Boobs and hips and ass all of cartoonish proportions. They came right up to her running their hands through her fur. She gulped feeling there touch. She couldn't help but reach out. Running a hand down them she found them smooth, perfectly so, like smooth shiny rubber. She gulped again feeling as her lust began building in force. She just looked at them, both of them more or less carbon copies of the other. Golden brown rubbery skin with pink highlights in their golden synthetic manes. She looked down at their bodies seeing their slits dripping.

Their legs were heavenly to look at as well. Smooth and shiny as the rest of them. Defined with muscle and curvature that only added to Tracy's deepening want of them. Looking all the way down she saw there hooves and her hooves. She had hooves now too. She gulped wondering when that part of the transformation had occurred. It was a thought that lingered no longer than it took be said. Discarded as both of the mares dropped down and buried their muzzles in her crotch. Tracy quivered at that feeling as their tongues came out and began to lick her. Her balls, her cock, everything about her genitalia was worked over.

Tracy was overcome by her lust at that moment. She couldn’t process the amount of things her body was feeling and in that moment she just let go. Tensing she came dumping a massive load into the air as both rubbery mares looked up frowning that it wasn’t filling them up. Then they stood up. Tracy was reeling from her first male orgasum and found herself being directed by the the mares. They were clearly not done with her yet. She felt them push her and she fell into a lawn chair. It was already inclined to the maximum. She just looked up seeing the hungry eyes of the two mares as both of them climbed on to her.

One straddled her face sitting on it placing her wet and dripping pussy on Tracy's face the other one came up from the other end. Licking her cock once more before climbing up and hovering her dripping slit over it.

“Come on big guy give us girls a nice ride will ya.” one of them said.

With that Tracy's body seemingly went into auto pilot. She jerked up bringing her cock into one of the mares and enjoying her load crying whiny in response. Her hand pulled the other one down further onto her face she began to eat the mare out. She tasted the pussy delighting in it. If there was one thing she was confident in it was her ability to please another woman.

Both mare cried out whinnying to their heart's content as they felt the stud under them use them for her own pleasures. The one on Tracy's cock moved up down with adding to her next climax which she could already feel building. Tracy moaned as much as the two mares she had on her. She wanted more thought and wanted to feel such things as only her new body would allow her. She pushed up into the mare on her face more eliciting another whinny.

The two mare reached out to each other bracing themselves and then looking at each other. They smiled leaning over and grabbing onto each other, interlocking both their rubbery tongues as they enjoyed the fine stallion below them. Behind them the other mares cried out. But the trio didn't care as they were too lost in their own pleasure.

The cycle counted for an indeterminate length of time until finally Tracy's body could hold back no more. She pulled the one down onto her face as hard as she could feeling as her body trembled and climaxed. The other one slammed her rear down onto her cumming cock and cried out both whinnys filling the night air with sounds sexually release and deepening pleasure.

Afterglow came and all three rested for a moment before a voice called out.

“I’m ready for you girls. Come back over here and have some more fun.” The other stud in the hot tub said.

Tracy looked up smacking her lips. Her mouth wet from pussy juice her cock much the same. She looked up and saw as the two other mares came up to her. Their pussy's wet and full of the other stud's seed which dripped out. They wanted her as well. She thought smiling at them.

“Would you ladies care for a ride?” she asked smiling confidently as she looked at them her mind pushing all thoughts other then pussy out of her head.

Their giggling laughter as they advanced and took up similar positions to the other two was all she needed in answer. Tracy looked up at the rubber lips of the mare above her and licked her lips as she felt the other one lower herself onto him. Smiling she took her hands and gripped the rubbery flesh of the mare above her and pulled her down on her face. Beginning what would be a very pleasant cycle of fucking for all four rubbery mares.
