So You’ve Been Transmogrified:

Horsey House Party Part 7


Sasha giggled as the door closed behind her and Liam. She turned around and handed his drink back to him still smiling as she wrapped her arms around him leaning in and planting a kiss on his lips before leaning back and taking in their surroundings.

“Wow, the boiler room. How romantic.” She said smiling warmly at her boyfriend.

“Cut me some slack, I tried all the other rooms down here.” He said smiling as he moved his hands down her back slowly.

Sasha just giggled a bit more as she took a step back and finished off her drink. She made a face as she tossed the cup to the side and stretched a bit.

“You get used to the taste of that crap?” She asked still mid stretch.

“A bit, kinda grows on you after a while.” Liam answered looking down at his own drink.

“You’ll eat just about anything, won't you?” Sasha asked playfully as she took her top off revealing her bra.

“Yourself included.” Liam answered smiling playfully back at her as he finished off his own drink.

Sasha smirked and chuckled a bit as she came back into Liam's arms smiling up at him.

“You are so fucking corny.” She said leaning into kiss him briefly again.

“Only for you.” he said running his hands down her exposed sides towards her pants.

Neither had planned on it but something about the party was really getting them in the mood tonight. Neither of them had felt a spark this hot in a few weeks. Between finals, life and a dozen other things neither of them had thrown much time at their relationship in a short while. Now however they could barely keep their hands off each other. Not that either of them minded. It just took a bit of doing to find some privacy, granted the boiler room was a step down but hey when in a frat house.

Sasha leaned back into Liam more heavily this time taking charge as she often did. He ran his hands down and fiddled with her pants a bit before sliding them down to the floor as well. Sasha stepped out of them and kicked them to the side with her shoes as she broke off of Liam and smiled at him. She tilted her head to the side a bit. Something was off, she was as tall as Liam and yet, she thought that she was a bit taller now. She blinked thinking about it a moment longer before she felt him slowly running his hands back up her body towards her bra.

She pushed the thought aside for the time and closed her eyes, letting the sensations of her boyfriends hands get her revved up. She was already plenty ready but a little foreplay went a long way. Which her damp panties could attest to as she felt him undo her bra with a single swift motion.

“You been practicing?” she asked, placing her hands on his hips and smiling at him.

“Just a little.” He answered back diving into her again as his hands headed south now.

Something about the moment still felt off to her. It felt good to be sure. The sensations of the moment crisp and clean, vivid and potent, deep and strikingly pleasant. Yet it felt in a way like a dream almost, distant from reality. However it was very clear as she felt Liam's hand dip into her waistband that everything here was very much real. Both his hands pulled down on the article of clothing moving it down her hips and thighs until it dropped leaving her naked and exposed to him.

She broke off from him as he placed his hands on her hips and looked up at her slightly. Sasha was again confused but shook her head of the notion, nothing was getting in the way of this she thought as she smiled at him.

“It's been way too long since I’ve seen you like this.” Liam said his eyes looking her over but coming to meet hers as he spoke.

“So I still got it then?” she said playfully smiling at him.

“In spades.” he said rubbing her rear seductively in the way he new got her going.

“So where did you wanna start?” she asked, leaning closer and smiling widely.

“Oh I think you know.” he said matching her smile as he took his hands off her.

She did the same and just watched for a moment as Liam disrobed. His shirt came off, his shoes, his pants, his undies. Over all he was not the most striking man. But that mattered little to her as she came right back up to him running her hand over his naked form now enjoying it as much as he enjoyed hers.

“Time to get to work baby.” she said running his hands down and grabbing his ass lightly.

“I love it when you tell me what to do.” he said hunching down and then lying on the floor.

The floor felt cold on her feet and she imagined that it wasn't doing Laim any favors either. But once down there he looked up at her smiling a stupid grin.

“Great view from her.” he said looking at her exposed sex.

“God, why do I even let you talk.” Sasha said leaning down as well resting on his chest as he exhaled a bit.

She crawled up to him leaning down and planting a quick kiss on his lips before turning around and hanging her now dripping sex over his head. He looked up smiling as she lowered herself onto him. Liam wasted no time running his tongue up her wet lips and gripping her thighs as she put her full weight on his face. Even this, one of their favorite preludes to the good shit felt miles above and beyond how it had before.

Sasha flushed red feeling overwhelmed by it. Her sex feeling more stimulated then it ever had before. She moaned as she looked forward seeing Liam's cock hard as ever and smiled. Still got off to this did he. She smiled loving just how compatible she and he were. She took in a deep breath bringing her head down and closing her eyes. Her mind drifted a bit but Sasha gulped as she found one of her recurring fantasy rearing its not unwelcome head.

Sasha bit down on her lip as the images in her mind formed around the sensations of her body. In her life there was a singular point of shame when it came to sex. Something that she kept close to her chest away from even Liam who she was almost certain wouldn’t judge her. Yet she still kept it far and away from him, in a way. From time to time the thoughts and ideas that she craved wormed their way up from the back of her head and presented themselves in singular detail and focus to her. Normally in the middle of one of these acts of lewdness.

Horses, powerful, furred, sexy horses. Her mind painted pictures of them in the moment, one of them being her. In a position not dissimilar to her now. A thick equine tongue invading her imagined equine pussy. Defiling it, pleasing it, using it. Warming her up for what was to come. She was soft in her mind's eye, covered in a light brown fur with accents of black around her hooves and muzzle and ears. Her lover was covered in fur as black as night. She threw her head back feeling as her mind blended the reality of the moment and the fantasy into a picture more real than any she had seen before.

She felt such things in those moments as she had only ever thought about in passing. Her fantasy feeling to her as if it were real. As if the massive jet black stud with his thick and dextrose tongue was really there diving into her equine pussys thick lips. Her tail swishing as he went on, pressing deeper into her as her mind wandered to things yet to come. His cock, throbbing and huge, flared and dripping with pre. Her own body trembling ready and waiting to receive it and to experience it in its full and glorious majesty.

She felt Liam below her slapping her ass like the good mare she was. So lost in the moment was she that she failed to notice the reasoning for Liam's slaps. She was growing. Larger and larger by the second and Liam was trapped under her. Her warm slit getting bigger engulfing him into its warm wetness as the growing weight of her body kept him pinned down to the floor. She tried to get her to stand up to no avail rapidly smacking her rear as he tried to yell. His cries muffled by the pussy most of his face was stuck in.

Sasha still in the dark merely interpreted the slaps and pleasant sensations from her sex as Liam going to town after being denied her sexy equine pussy for so long. She smiled at that as reality and Fantasy fully blended in her head. She was Liam's mare, a hot sexy warmblooded thing that he lived to please. She raised her head smiling as she felt all the warm radiant sensations running up her body.

As she let her mind drift her body began to further shift. Liam grasped her ass trying in vain to push her off. He found quickly that her growing size coupled with a lack of leverage made that a pipe dream. Then he felt something odd, hair? He thought as he stroked what had been seconds ago smooth skin. He gulped as he then felt something in his head seemingly click into place. This was kinda hot, being trapped under his girlfriend nothing but her ripe sex in his face. He exhaled as he again rubbed her now furry ass.

It was nice, soft, and warm. He sighed as he did the same with the other side. He stopped fighting and leaned into it his own mind becoming over come with a sudden and pervasive lust. From their growing lust rapidly quelled any lingering fear about being trapped under Sasha's still growing ass. If anything he wanted it bigger, thicker, juicer. He thought as he ran his tongue back over her dripping sex.

Sasha cried out at that feeling as her boyfriends advance sent her spiraling further and further into equine fantasies. She could feel his hand running through her fur, sending dim but nonetheless welcome sensations up her shivering body. Everything about the moment built upon itself. Each bolt of lustful energy compiling towards an ultimate climax. It kept up as Sasha lost more and more of herself to her fantasy, less human, more horse. She pictured Liam and the stud each one interchanged between bolts of ecstasy until the two were the same in her head.

Then finally it came to her. In a single moment there was build up, there was release, and there was the climax. She let out a cry screaming into the air as her world was rocked. Yet as she did the cry changed in her throat deepening until what came out was a loud feminine equine whinny. It felt right to her deepening the moment as the cry in her throat waned and the afterglow of the moment settled in. She took in deep breaths as she leaned back letting her still trembling sex press harder still against her lovers face.

She brought her head down smiling as she turned to see the sight of her lover's face buried in her ass but blinked instead lunging forward off of him as she tried and failed to stand up. Liam took in a deep breath as she did finally being freed from her sex grip. He looked up at the ceiling breathing heavily for a moment his head soaked in the juices of his lover before he looked forward and saw a sight.

There before him was Sasha, chest on the ground, ass held high, and among other things parts of her looking very much not human. He blinked seeing the warm brown fur covering her ass and legs. Her wet slit with it puffy lips and a donut shaped puckered ass. A tail was forming now swishing back and forth. Sasha lay there clearly trying to stand but failing. Her back seemed to not be shaped that way any more. Laim got up and walked over to her gazing as her rear seemed to grow before his eyes. Her legs stretched further pushing her off the ground as she whined a bit.

“AH fuck there shrinking!” Sasha screamed.

Liam knelt down and blinked watching as her tits did just that seemingly deflating until there was nothing but chest, even the nipples melted into the skin leaving her chest void of any such things. He blinked remembering something from an anatomy class and looked to her rear amazed as he watched them grow in just below her sex, not as big as they had been but there now regardless. He gulped looking back down to Sasha.

“Uh, are you ok?” he asked hoping to find better words but failing.

Sasha took in a deep breath and looked over at him wincing in pain he thought.

“As weird as it sounds, yeah I do. This feels, pretty fucking good actually.” she said wincing as Liam blinked.

“Good?” Liam asked blinking as he gazed at his girlfriend's still growing rear and noticing that the fur from it was now spreading down her back as well.

“Everything just feels so…” Sasha tried to say as she sighed out a trembling breath. “So good.” she finished trembling again as Liam gulped equal parts confused, aroused, and scared.

“Liam, uh… look this is a weird request but uh, could you maybe fuck me like this.” Sasha said without looking at him, her face still buried in the ground looking like a horny mess.

“What? You have a horses ass and you want me to fuck you?” Laim said gulping as he said so kinda wanting to.

“Look, you don’t have to its just uh, oh fuck that's good...” Sasha said turning her face to the ground and moaning as more of her body changed.

Liam could see the muscles now, thick powerful things spreading under her skin. Turning her further into an animal. That was kinda hot. He thought gulping seeing as skin turned to fur and fat to muscle. He got up and walked around her hearing as she moaned even more as the changes seemingly hit another high point for her.

He walked around her gazing at her changing body and gulping as he did so his opinion of it increasing. Her legs were toned and powerful, her thighs, muscular and covered in fur that only added to their looks. Her pussy, puffy, wet dripping with her juices. Her ass puckered looking more than a little inviting. The way her tail danced around fluttering in tandem with the shivers that ran across her body. His own body trembled a bit now. He could feel blood rushing down to fuel his erection as he drooled a bit as wondering what it would be like to mount the changing woman. He looked down seeing her hooves, she had fucking hooves.That was in a weird way also kinda hot.

He came back around and leaned down looking at Sasha for a moment before she looked over at him. She smiled at him before gritting her teeth and burying her face into the floor again. He looked at her body again seeing her chest expanding as the fur grew over it. She leaned back pushing up a bit as he saw her arms lengthen a bit, and then a lot. Then he gulped seeing her fingers fusing as they turned into solid masses darkening until they clopped to the floor as a pair of hooves. He blinked horrified and yet still somehow turned on.

He looked back to her face and saw through the panting and gritted teeth a lingering smile. She was loving this wasn't she. Enjoying each sensation even as her human appearance waned. He gulped. She looked over at him breathing heavily as she smiled.

“How do I look?” she asked her smile widening for a moment before her she sighed out breathing heavily.

“Weird, but uh kinda nice.” Liam said looking over her body quickly again.

“Nice enough to fuck me?” she asked smiling at him noticing his erection.

“How can you think about something like that right now, your turning into a fucking horse!” he said gulping as he thought back to her dripping pussy his wanting to do things to it deepening.

“Look tldr but uh, I’ve kinda always had a thing for horses alright. We can worry about all that shit later but for now.” she took in a deep breath wincing a bit as her arms grew upward to match her legs evening her out. “But for now, please I am so fucking horny right now, just please, just…” she winced again and Liam watched as her arms grew larger, thicker and more muscular as the fur ran over them until her two front legs were almost identical to her hind ones.

She sighed out again breathing heavily before wincing again as her neck started to thicken and expand. Liam just watched now wordless as his girlfriend fully turned into a horse. He couldn’t look away watching as the fur spread up her lengthen neck taking hold of her face. It lengthened rapidly pushing out as it deformed and pushed further and further out into a muzzle. Her ears grew longer and longer moving up the side of her head slowly. She winced one last time closing her eyes as Laim heard the cracking of bone and then an audible sigh.

Sasha tensed in one moment and then relaxed in the next letting her head fall down as she panted still horny as all hell, but feeling considerably better now. She held her head up panting before smiling at him.

“That was uh… something else wasn't it.” she said chuckling a bit.

Liam took her muzzle into his hands and looked at her closely.

“Your a fucking horse.” he said looking her face up and down.

She smiled a bit, “Am I a sexy horse.” she said giggling a bit as she felt a bit of her lustful energy return to her.

Laim blushed a bit, “Sexiest horse I’ve met, I guess.” he said looking at her still.

Sasha smiled at him before raising her head up all the way and looked down at him grinning. Regal, powerful, and despite lacking humanity, sexy as she ever had been. She looked at him smiling and then he saw her eyes dart downward towards him. She came back to eye level with him smiling in a perverted way that made him gulp.

“You ever get your dick sucked by a horse sexy.” Sasha said smiling as she looked eye level with the man who blinked at her before answering.

“Can’t say I have.” Liam said gulping.

“Do you wanna?” she said her voice dripping with lustful intent as she smiled at him.

“Fuck it, have at it.” he said gulping as Sasha leaned down and opened her mouth wrapping the man's cock in her warm wet equine tongue.

Sasha smiled a wide equine grin as she tasted her man hearing him moaning and groaning. The feeling of him as he leaned forward wrapping his arms around her thick neck as he braced himself against her large form.

“Fuck babe you feel so good.” he said gasping and huffing the words out she giggle in delight enjoying her lovers glee.

Her imagination took further hold of her. Her thoughts turned to the cock in her mouth. While her Liam was not lacking in size for a human, he was for a horse. She sucked him off harder working his throbbing member as she lusted and wanted him to grow to a larger size. He moaned louder and louder gripping her fur as he thrusted up and into her mouth. She wanted him bigger, wanted a cock worthy of breaching her equine sex.

Her smile widened even more as she felt her man trembling against her. His body leaning into her every action as she pleased him more and more. The more he did, the more she wanted him to be bigger. To be a horse that could please her properly. Inside her mouth her wants turned to reality. Slowly at first Liam's cock grew. Already hard as he could be Laim was slow to notice his changes. He was too wrapped up in the feelings of his wife sucking him off.

However as his cock swelled well larger than a humans had any right to be he took notice. Liam moaned out as he felt the deepening sensitivity while Sasha maintained her lustful smile. She enjoyed the feeling of the cock in her muzzle even more so now knowing that her lover was growing to a size that would be worthy of her. She could taste as the cock left behind Liam’s human scent. It changed depending with earthy tones until it was a scent and taste that while still recognizable as his was something infinitely more attractive to the mare.

Sasha could feel it pushing further and further into her throat filling her mouth more and more. Then she felt Liam grab her tightly. The man winced and cried out thrusting up into her mouth as she could feel his still growing cock tremble. His cry turned into a whinny like the one she had let rip before. Yet his was deeper, reverberating in her lust drunk mind as the sound of a pleased stallion. She felt his warm seed enter her mouth smiling as she tasted the fruits of her labor coming from the still growing cock.

Liam leaned heavily on her now taking deep breaths as she worked the man’s still coming cock for all of its worth. He trembled letting the mare simply work his cock. Then after what felt like hours of near continues nut busting he relaxed leaning on and holding Sasha's huge form.

She pulled off of his cock seed still dripping from her mouth a feeling of tremendous satisfaction in her and displayed on her muzzle. She Picked her head up a bit and nuzzled her boyfriend who smiled and nuzzled the horse right back. He looked down then blinking and gulping as he felt the weight of his equipment dangling between his legs.

“Holy fuck.” Liam said gulping taking a hand and feeling his now two foot long cock and grapefruit sized nuts.

It was mottled, bits of flesh colored pink and brown in a splattered pattern over it's still moist surface. He could feel his balls churning getting ready for another expulsion of their seed. He ran his hand down its length shaking a bit as he brought his head down and sighed. Sasha leaned back in and licked the tip with her tongue grinning as she watched her man tremble and tense at the sudden and pleasant sensation.

“So, you just gonna stand there all night or you gonna use that thing?” she asked smiling at her lover in a lustful way.

“Use it? You mean like? On you?” he said gulping. “But, I mean your a fucking horse.” he said thinking out loud, but also feeling as his body heated up at the thought.

“Honey, this horse just sucked you off. Also you have the right equipment for it.” She said leaning down nuzzling his cock feeling his power and trembling a bit herself.

“But… But…” Liam said wanting to protest but also feeling as his cock got harder at the thought of mounting his equine girlfriend.

He gazed at her with lovers eyes. She was larger, powerful, and sexy. Despite the fact that she was a horse he could still find traces of his Sasha among her animalistic form. Her eyes, her smile, her face, muzzle or not was still hers. Her legs, a point of deep interest for him were all the more attractive now, plus there were four of them to savor now. Each one toned and muscled in ways that while not human were no less attractive to him. He took a hand running it through her fur as he walked around her. He felt her coat, soft and warm. He gulped rounding her rear seeing her plump ass, thick equine donut, and her large pussy, puffy lips dripping with anticipation.

His cock stood erect at that. It was hard now calling for him to insert himself into the folds of the hot blooded mare before him. He took in a deep breath taking his hands now and placing them on her rear. There was a slight issue of her being taller than him. He gulped now running the numbers in his head as he dug his hand in her fur. This caused Sasha to whinny a bit as she felt the lustful pains of waiting start to set in. She wasn't sure what Liam was doing other than groping her rear but she knew she wanted him in her sooner rather than later.

"Enough foreplay honey come please, just take me." she said in a needy voice.

Liam said nothing and Sasha tensed again feeling as his hands shifted slightly. Her mind was still wondering what he was doing when she heard a grunt and felt something poke at her rear. Instantly she felt it, his massive cock fully inside her. Her mind playing catch to her body for a moment as she reared up whinnying loudly as she felt her lovers hand dig into her fur. She cocked her head up her mind overcome with bliss as she felt her lover hump her rear resting his fully body on her as the man assaulted her rear the best he could.

Liam's legs were about a foot off the ground. His hips slammed into Sasha's as he tried his best to fuck his mare. He was starting to think in such terms her the mare, him the stud. It added to the moment he found. No human issues, just pure beastly pleasure shared between the two of them. He humped and humped feeling as his massive member was milked by his mare. He pumped her the best he could but with no leverage there was only so much he could do. Both of them wanted him to be able to do more. To be more of a stud.

With that he could feel himself changing. His body expanding, his muscles swelling, his extremities lengthening as he thrusted again and again into his mare. Sasha could see him in her mind's eye now as a proper stud. His body turned to match that vision as his changes progressed further. Glistening jet black fur all over his body. Toned and muscled legs bursting with power. Thick black hooves. A long equine face pushing out from his old human one. She could feel him as the thoughts turned to reality, his thrusts growing more and more powerful as his weight increased. She could feel his body growing as he rested on her. Then she heard it.

Two clops, nearly simultaneous and then the first real thrust of the night. Using his longer and now fully equine legs Liam thrusted into his mare with reckless but passionate abandon. Already fully overtaken by his desires Liam had nowhere to go as the sensations mounted in his mind, compulsions to breed the mare under him deepening, urges to claim her rising, the need to protect her growing, his love for her at the front of his mind. He licked his changing lips feeling as his face started to push out and black fur ran up his thickening neck.

He delighted in the sensations of his changing body. The way his hands and feet had felt as they fused turning into hooves. The way his muscles felt, electric with pure and raw lustful energy all of which he directed towards his mare. The way his fur felt creeping up on his skin, tingling and sending shivers up his spine as it grew over more and more of his body. The way his chest ballooned outward rounding and growing as his body turned into that of a proper horse. The feeling of his joints shifting slightly as his arms turned into two more legs.

He could feel his tail swishing now having sprung and quickly grown from his rear. Even that felt amazing. His tight and now toned ass puckered and waiting for something. He licked his lips again thinking about letting another stud mount him as he did Sasha. He could feel his balls aching, churning, demanding cause to be allowed to dump their cargo into the mare.

Yet Laim held out waiting just a bit longer as he felt the tension in his face. He felt the pressure, heard the cracking of bone as he took on a strained look. Fur crept up the side of his lengthening face. He could feel his will to hold back waning as his climax drew closer. His breaths turned shallow, his breathing uneven and thrusts less and less measured. All his movements turned wild, but gained in force. Then with one last crack and a final tingle of fur over growing skin Laim relented.

The now fully equine Laim, jet black and oozing with a power only a muscled equine could have pulled back feeling as cock was on the brink. He exhaled and then taking in one last shallow breath thrusted into his mare as his seed exited him beginning to fill the mare below him as he cried out loud a thunderous whiny.

Sasha reeled, her mind blanked by the moment as she felt her peak hit and then surpassed as her body tensed and she too reached a climax. She could feel the trembling cumming cock in her dumping its warm load into her, filling her. She whinnied there savoring the peak of the feelings as warmth slowly rolled over her. The moment stretched out, seconds into minutes. A long sigh left her mouth as she lowered her head down and then felt Liam's join her there.

He rubbed his muzzle against her own brown fur. She couldn't really see much of him though and just enjoyed the moment. The warm after glow of there fucking settled in and further relaxed the two equines.

“So… uh… you like being a horse?” Liam asked a few minutes later.

“Yeah, you?” Sasha asked not thinking about the question too hard.

“It's, uh… nice I guess. But I mean uh… well… you liked them before this didn’t you.” Laim asked shifting his weight a bit.

“Uh? Wait. Oh you…” Sasha blinked her eyes going a bit wide as she processed her stud's words.

“Did you uh… know about all that?” She asked nervously.

“What that your deep dark fantasy was about getting rammed by a powerful jet black stud. Like myself.” he said rubbing his muzzle against her.

“How did you…” she asked trembling slightly as she felt him shift and come off her pulling out of her and leaving her feeling a bit empty.

“Wow, this is kinda weird.” Liam said as the still shaking Sasha turned to face the other horse.

She gazed at his form, jet black, sleek, powerful, sexy in a way only a horse and never a man could be. Yet still possessing all Liam's best qualities, it was enough to get her sex to treble and picture hi on top of her again.

“So uh… I’ve known about it for a while. I mean, you talk in your sleep and uh.. You say some uh… well let's say very descriptive things. Plus you also never delete your browser history and what with autocomplete and all…” Liam said turning his head around and around as he went on.

Sasha came up to him nuzzling her stud with her head smiling.

“So you don't think it's uh weird or anything?” she said waiting on the words.

“I mean, maybe a bit. But given the way things are now I’d say it's kinda hot.” He said watching as his brown mare backup and smile at him before leaning in and kissing the side of his muzzle.

“Thanks, I love you.” she said nuzzling him again.

“Me to.” he said nuzzling her back.

“Now, how about you fuck me silly again you big stud you.” she said whispering it into his ear as she smiled.

Liam smiled and jumped up on two legs ready to whinny but came crashing back down.

“OW.” he screamed as a load clank resonated through the room. Both of them looked up and saw a chunk of pipe now missing from a collection of them on the ceiling.

Both looked down at each other before smiling.

“So, is that yes.” She said turning around flicking her tail at him suggestively.

Licking his lips as he said yes Laim mounted his mare again thrusting and thrusting as his cock hardened and the pleasure deepened blocking out the pain from his mind.

Above them the air intake for the house sucked away no longer pulling from the vent on the outside wall but from the room now filling with the musky scent of hot and heavy equine sex.
