Piper Sanders was spending her Saturday evening like any other Senior teen girl with little to do, laying on her bed feet in the air as she talked and texted her peers... However, as popular and mature as she claimed she was, she still had to live with her small family in their cramped home. And even worse she had to deal with her absolute dweeb of a little brother. He was only slightly younger then her but was such more of a straight-laced pudgy nerd that was way to interested in Chinese cartoons and games than any one should ought to. Unlike Piper, who always made sure to take care of herself, both literally and by making sure everyone loved to help the perky, hour glass shaped teen. Her brother always had to one up her or make a fool of himself by actually offering to help in matters that shouldn't concern him. But, he mainly stuck with his gaggle of nerds or kept to himself when not, so it wasn't to hard for Piper to rule and enjoy the house to herself on nights like these when no one else was home.

Piper had no idea this would be the last night she'd enjoy to herself....

The conversation she was currently having with her online peers was something about Beastman rights and would liking them be wrong or progressive and who was going to Ken's party tomorrow. All of which Piper was eagerly involved in, talking about how as long as they were kept separate from people who were allergic or scared of Beastmen who couldn't be accepted? Then eagerly gossiping about what the other girls did or who was going to what party. Along as her looser of a little brother stuck to his room, tonight would be a good night for Piper.

As the night dragged on, and Piper grew bored with idly texting and gossiping with her friends she decided it was time for a late-night dessert. Firstly, she decided to set up her tv for some quality horror movie streaming, Afterall, what better time than at night and alone? Or well, practically alone. Besides the occasional shout or even what sounded like a growl from her brother's room when he seemed to get to excited about whatever game or thing, he does by himself, the house was all to herself and usually pretty quiet. After a moment of finding the right stuff to watch she queued up her chosen programs and started to head down to the kitchen. She opened the door and walked down the stairs, paying no heed to the quite growling coming from her brothers' room, passing it off as either just sound effects or him being just weird.

The kitchen was just pass the living room, and was close enough to the Front door that anyone could see straight in to the kitchen from there. A Large wooden table stood visible for all guests to see the moment they entered the house. Piper never liked the kitchen table, she hated spending anytime with her lame family. But luckily for her, this was her night. She eagerly swung opened the Freezer door, looking for ice-cream or another dessert as she could faintly here large steps coming down the stairs and into the living room behind her... then before she could ask her brother to knock it off with whatever the hell he was doing she smelled something strange.... cat. She turned to address her looser brother but Piper gasped as she saw only the form of a massive cat man approaching behind her, she started to yell but only squeaked as she was lifted up by her tight shirt. The Beastman was two heads taller then she, and was very large, accented by a pudgy belly and large swollen muscles and feline fur that made the Beastmen look like a monstrous Tabby cat. Then the realization hit her! The monster was what was making those sounds because as she looked at his large feline head she saw features that immediately reminded her of her brother! His shaggy brown hair intermixed with is fur coat... his pudgy belly and as she looked at his stretched and torn clothes that barely clung to his massive feline form she noticed something else... his throbbing ten-inch beast cock.... it was complemented by two swollen furry oranges that were once small human testicles and was very feline in shape! She gasped as she tried to talk some sense into her beastly brother.

"D-damnit b-bro you're a monster! W-what are you doin-" she almost gagged as her loud cries were muffled by her beastly brother's large feline lips and tongue filling her mouth. She tried to resist but it was in vain, her brother's monstrous power overwhelming her feeble strength as her mouth was forced to suck on his large thin lips as his long rough tongue explored hers. She looked pleadingly into his eyes but only sough hazy, intense feline eyes that just stared deeply into her.... she could smell his arousal and musk, especially as she tried to hit and scratch at his tough feline form, doing nothing but maybe giving him a little pleasure at the attention as he seemed to start to rumble off a deep purr... she panicked as he sucked on her face, feeling nothing but a mix of sweat and strange oils on her hands as it was rubbed of her brother's fur... she couldn't see it but she did feel her hands start to tingle as they seem to become stuck to his back after a while of feeble tugging and pulling, however she didn't know that it was because they were swelling in size ever so slowly as they started to grow puffy little pads... Completely at her changed brothers mercy she could only hope someone would come and help her! She was on the kitchen if she could get away...

"bam!" Piper's thoughts were shaken away as she felt herself being thrown onto the kitchen table. She grunted as she yelled out. She desperately yelled for her brother to stop but it was only met with more deep purring and soft moans. Then with what seemed to be a smile the beastly form of her brother softly growled.

"Beastmen love their family, Beastman serve and make more eager breeders for me~" he purred as he started to slowly claw and tear of her panties, piper pleaded but was surprised to be pinned down by her brother again, his large feline arms holder her down as she noticed that her own arms seemed to grow heavy and stuck against the kitchen table refusing to raise against her beastly brother, she quickly saw why. Getting as best of a look as she can she noticed that her small feminine hands were now larger, covered in tabby like fur as claws dug in to the table! She started to scream again but the second she did two things happened almost at once. Her brother's feline maw filled her mouth again, and this time she instinctively started to lick back as his beastly tongue and mouth dominated hers, and her naked pussy lips were being squeezed around the pointy and throbbing feline cock of her very beastly brother. She felt her body twinge with shock and forced pleasure as she was forces to suck on her brother's feline mouth, his saliva filling her mouth. A strange taste that she couldn't identify overwhelmed her senses as her body grew unreasonably hot. She cried silently, not knowing why her brother was a Beastmen that was so desperate to rape her or why her body was growing so hot and heavy as she was forced to accept his beastly advances... again she couldn't know what was going on but she could feel that her body was reacting to her brother's new feline form, a thought that was causing her no end to her embarrassment and shame as he she felt herself near and orgasm! All as her now furry brother violently dominated her... then it happened... she came, her whole body twitched with pleasure as she felt her feminine juices gush all over the large beastly member of her brother. She hated how she felt her heart flutter as her whole body grew hot and excited by her situation, but she couldn't stop it either. Nor could she stop the feeling of her well groomed bush growing larger and larger as it became a furred Forrest, spreading from her wet and stretching pussy lips up her crotch, all as it starts to sport a tabby like fur pattern... She involuntarily moaned and gasped as her body spasmed from the orgasm, as she did so she was instantly overwhelmed by the intense heat burning in her insides, the forceful orgasm and constant face sucking from her beastly brother was doing more to her body and mind then she wanted to admit. Even though she wanted to scream or fight back her body and brother wouldn't let her, even worse her body was enjoying the stimulation, a thought she desperately tried to fight off. However, as she succumb to her bodies orgasm, she now had a new problem... her mouth and nose were growing very wide and dark as her face starts to contort and push out from her face as fuzzy, tabby fur starts to creep around her morphing face. Her nose and mouth was also being overwhelmed by her brother's new and admittdly very pleasantly musky scent and saliva that was spreading all over her tongue and throat due to her involuntary moaning. She could feel her body start to grow and change each moment she exchanged fluids with her changed brother... her hands were now very much feline in form and function, with large puffy pads under her large, furry let still femenine digits that clung and clawed at the table locking her arms in place as her larger beastly brother had his way with her. Her virgin pussy was rapidly growing wider and slightly looser as it hugged and gushed over her brother's almost foot long Beastman cock. Her femine bush completely over taking her gorin and lower body as it rapidly grew into a furred forest a fact piper had no immediate knowledge of but could feel a strangely warm and pleasant fuzzines enveloping her waist that completely escaped her panicked mind. Her ass was doubling in size under her. A fact unknown to Piper but was a welcome change for the very horny Beastman that once was her brother. He aggressively groped and rubbed her plumping ass in his large, free hand as he sucked on the changing human's face and lips. Her small round tongue and soft lips tasted really nice! And his master was right! The human bitch was needing to be showed affection from an alpha Beastman! She could yell and scream all she wanted to, her moans and gushing pussy was all he needed to see to know she was waiting to be shown that she deserved to be taken by a real Beastman like him. And to see her body naked and avalible to him as her soft body grew larger and furrier drove him uo the wall! Human's did want to become like him! It felt so good to feel his paws and arms grow and rip out of the constraints of the human garb he was forced to wear; no longer would he pretend to be a human servant for this needy bitch or her kin! He was a Beastman like master said and now he'll have his very own bitch! He moaned and purred as he smelt this bitch's rising heat, her ass filling his hand and then some as she moaned and gasped in his maw. Her eyes were red with tears but her moans and body was screaming for a mating, and as any good Beastman should, the feline that once was Piper's brother prepared his loving bitch for mating....

Piper tried to talk to her brother, she tried to yell for help. But each time she tried to speak she could only gasp and pant. Her mouth felt to funny, her tongue different, it almost felt dry if not for all that tasty saliva her mate... wait! What was she thinking? Why cant she feel her arms or legs? She desperately tried to feel for her limbs but she felt something else, fur... and heat. It was spreading all over her it was making her pant. That's when she saw her mouth! She could actually see her mouth! It was stretching out from her face and it was changing and it felt so... good. She knew this was wrong! She knew she needed help but her body was loving this, even worse. She was changing into monster! Her brother moaned and growled softly as he broke away from the face sucking, his large feline face eyeing her up and down. Then it she felt a new force. It wasn't her brother; it was her own body! Is popped and cracked and each time it did waves of pleasure assaulted Piper! Her ears felt fuzzy and the her hearing went out of focus and then she started hearing everything so much crisper.... Her panting and changing. Her brother's deep purs and moans sending shivers up her spine... Her spine! That's what was stretching and popping! She tried to focus on it, a mistake she instantly regretted because as she did she realized what was happening. Each crack and pop was a tail snaking its way out her back! And it felt so good it caused her mind to grow fuzzy with a mixture of intense pleasure and small stabs on pain. All she could feel the pleasure and heat of her rapidly changing body as she stared blankly at her br.... her br... she couldn't remember what she was thinking about! All she could focus on was her body growing and changing... the intense feeling of pleasure as her muscles stretched and grew. Her body fat bubbling up and swelling on her chests as her perky breasts swelled and gently lactated as the started to balloon in size as her upper body popped and grew.... fine tabby fur washed over her shoulders and breasts as her stomach muscles tightened...

"Meow kitten! What a sweaty and needy bitch you are! Don't worry~ this is my first time too~" The low growl of the words from the hung Beastman titillated and excited Piper, though she did feel that something was wrong... that she wasn't a-

"AHAH-M-MEOW~" The sound of his bitch screaming out in pleasure before she loudly mewed was music to His feline ears. Seeing and even feeling the young human bitch start to change in front of him drove his carnal lust to extreme heights! Her small human pussy stretching and kissing his shaft was one thing, but seeing her body grow in size and form as her chest stretched and tore any remnants of her precious human clothing as her breasts ballooned and leaked all over her much more appealing tight furry belly was too much! He pressed his feline tip into her enlarged pussy, and was immediately greeted with her vaginal walls calming down around his barbed feline member. She moaned and shouted again in intense pleasure but he wasn't paying too much attention to the last words of what once was his human sister. He was enraptured in the intense tightness of her virgin furry pussy that he eagerly thrusted and pounded. He clamped and rubbed on her furry waist as her legs, which now wrapped themselves around him, rapidly grew in length and shape as her small human feet popped and cracked as they started to swell into plump feline paws. Her head was now completely transformed into a properly cute feline's as only her hair still resembled what once was the human Piper. The almost feral fucking continued for almost fifteen minutes straight, a lifetime for the Beastmen enraptured by such a passionate mating. The bitch moaned and purred as she felt her virginity taken by her mate, a feeling that overwhelmed the recently transformed bitch and caused her to cling tightly to her mate, her claws sinking in his pelt as she desperately sucked at his face. For his part he violently bucked and thrusted into his needy bitch, going deeper and deeper as he purred and growled. The loud sounds of Beastmen sex echoing the trashed kitchen and even the house as a whole. However for the mating couple, this was bliss. For her part, the newly made bitch did her best to milk her mate's cock. The sensation of the large cock coupled with its pricks and barbs rubbing her pussy walls drover her wild. The intense pleasure of having her virginity so animalistically taken driving her completely wild. Then it hit them, all at once the howled with wild pleasure as she felt the most intense orgasm rock her. Hot femenine juices gushed all over her mate's beastly cock only for his member to erupt in a jet of hot, thick feline cum that quickly filled his bitch's womb and belly. They moaned, purred and continued to kiss and ride out their orgasms for more than while until the Beastman pulled out. Warm seed gushed from his Bitch's pussy and all over the floor and table. The panted and purred before the Beastwoman spoke.

"s-so fucking hot.... T-that was what I needed~" She panted and looked to her mate, almost blushing as she felt her pussy leak all over.

"M-meow is right kitten~ do you even remember how you got here? How you begged for me to take you and make you the bitch you deserved to be?" The Beastman smiled as he couldn't help but probe and taunt the ex-human bitch. To this the Beastwoman smiled and seductively tweaked her wet nipples as she rubbed along her furry curves.

"i remember riding and claiming a big dumb stud like you~ I also remember you fondling my tits as you desperately mated me~" She smiled and purred back. Revealing that she really was completely changed into a proper bitch and a very sexy one at that.

"Say.... whats your name Stud? In fact.... who am I" The Beastwoman asked almost pleadingly as she tried to remember something, or anything about well anything about herself. The Beastman didn't know how to respond right away.... he too tried to remember what was his name and how he found this place and the human bitch... Then the words of his master came to him, reminding him how he was always a Beastman and that humans needed Beastmen like him. It was to show human how they were always meant to be loving beasts like the human bitch became.

"oh, feeling foggy are we? Hope we didn't get to tough on each other their kitten~ Im your loving mate that you were finally eager to admit your feelings for~ and you showed me this human house you use to hang out in. Don't you remember now? You were waiting for me to free you from this human family that forced you to act like them! Hehe, how you use to act was always so funny, don't you remember now: they use to call you a human with a fake human name. But you were always Kat to me~" and with that manufactured account, the last memories and traces of Piper was lost. The Beastwoman's mind conforming to every word of her mate's as she would forever be Kat, the busty feline bitch...

"Heh, I guess now I have to admit it then don't I... I do admit it did feel real... being a human... but I guess that's what they do to us..." Kat trailed off as her mind adjusted to her new reality, Piper now being completely lost to Kat.

"well then I guess from now on I should call you Felix then, because you always been my happy cat~" Kat moaned and purred as she stroked the Beastman's face. Just as he had done to her the new name for him instantly started to cement itself into his changed mind.... He too would forever be the Beastman Felix, mate to Kat.....

They purred and rubbed onto each other for a moment longer. their naked and cum covered fur rubbing on each others on top of a trashed and cum stained kitchen. Not a care in the world until the front door swung open and two gasps were heard.....
