Bitchy Yoga

Max was feeling royally pissed off.  His parents were both out again and all he could hear through the thin wall of his room was his older sister Amber getting royally fucked by her stud of a boyfriend Brandon and loving every moment.  He didn't dare interfere... Brandon was huge and would beat the shit out of him if he tried anything.  All he could do was sit here and listen to her getting pounded - Brandon's big balls slapping up against her ass as he fucked her doggy over her bed -  and the horny slut loving every moment of it.

"Ohhhh, ohhhh yes fuck meeeeee! Ohhhh your big cock feels so good in my tight little pussy, yes YES! Harder ohhhh fuck I'm gonna CUMMMMM! Mmmmmh!"  

Brandon scowled and tried to ignore the rhythmic thudding, squealing and wet slapping sounds coming through his wall... but it was impossible.  He couldn't believe how Amber was acting these days. She'd gone from a shy nobody into a mean Alpha-Bitch very quickly.  In fact six months ago, his sister had been a nerdy little book worm, then overnight she'd seemingly transformed into a horny minx with a fashion obsession and a tight body that drove men wild.

She claimed her new confidence and sex appeal came from taking up yoga.  She'd tried it for the first time six months ago after being given a sexy pink yoga mat for her birthday and had very quickly transformed into the bitch she now was... in fact, Max found it hard to remember what she looked like before she did.  Amber reckoned yoga had toned up her body, made her more flexible and given her the confidence to be a slut.  Well - if it had worked for her, maybe it would work for him?  Max was sick of being the virgin nobody in this house... maybe if he did some yoga he could get hotter and find a sexy girlfriend? Then he could annoy Amber by fucking his girl through the wall...

Dressed in his work-out clothes he went downstairs and found Amber's pink yoga mat.  Rolling it out on the floor, he climbed on top and using a Youtube tutorial off his phone began to exercise.  The mat below him smelt good - kind of girly and as he stretched out on the pink material something weird began to happen...

Pushing his ass high into the air, Max moaned as his bottom swelled and inflated and his shorts tightened - turning pink and sucking around his bum. Now he had the hottest ass at school... all the boys wanted to touch his tushy.

He giggled as he stretched out and his body shrunk making him petite - the perfect height for sucking jock cock. 

Pushing his chest down into the mat, he groaned as two firm breasts pushed out and his top shrank into a slutty blue sports bra.
Sure - he didn't have the biggest tits in school - but they were damn perky and they looked great on his skinny chest. He loved having tits... they really made the boys go hard.

"Ooooh, what the fuck is happening? I feel so horny," he gasped dizzy with lust as his hair turned blonde and he performed more stretches, his bones cracking and his body becoming incredibly flexible.

A wet patch appeared on his crotch as his dick sucked up between his legs so that a tight wet slit could open - his pussy aching to be fucked. He loved when boys stuck their fat cocks inside him... his tight cunt fit their dicks like a skintight glove and no cum ever escaped when he rode them unprotected. "Mmmmh I'm such a fucking cumslut..." he moaned.

Hot curves pushed out and his new yoga outfit rested more comfortably on his feminine curves as the changes slowed.

Reaching up to his face, Max felt soft pink lips and tanned smooth skin and he giggled as he tasted lipstick on his mouth and smelt perfume rising from his body.  He felt so girly and hot all of a sudden. He was such a fucking slut...

"Like... I feel really good today, I gotta play with myself," purred Mia as she took off her bra to free her tits and stretched prettily on the mat.  "Wait.. Mia.. that's not my name... is it?  Oh of course it is... I'm like such a dummy sometimes..." Mia was now a ditzy, horny, dirty little slut... some said even nastier than her bitchy older sister. She was the up and coming alpha bitch and was gonna be even badder than Amber in a few years time.

The newly transformed bitch now had no memory of ever being a boy, she had been transformed by the magic yoga mat into Amber's bitchy little copy-cat sister.  She just wanted to be an even bigger show-off than her older sister and was determined to have as much slutty fun as she could.

"Ooooh, I'm so horny, wish I'd brought my dildo down with me to play," she sighed as she rubbed her pussy through her pink leggings and got wetter and wetter.

"Holy shit Mia, you're even fucking hotter than your sister when you play with yourself like that..." laughed a deep voice suddenly, and Mia turned her head to see Brandon... her older sisters hunky boyfriend watching her hungrily from the door as she rubbed herself and her leggings were stained with her wetness.  She just giggled and continued to finger her pussy, feeling her nipples get hard as she let him watch.

"Mmmmmh, you little slut... I just fucked your slutty sisters brains out and left her drooling for more, but seeing you play with yourself is making me fucking horny again."

Mia giggled and provocatively stretched her lithe flexible body.  She spread her legs invitingly and blew him a kiss. "Then why don't you come fuck me stud and let off your frustration?  I'm even tighter than she is... all the boys say they never cummed so hard as when they fuck me..."

Amber was passed out upstairs and this cocktease was too hot to ignore.  Tearing off Mia's leggings, Brandon grinned as he bent her over like a horny fuck doll and quickly pushed his massive cock deep inside her. Mia was so flexible she could put her legs behind her head as he reamed her. She squealed in pleasure, her eyes rolling back in pure ecstasy as he began to fuck her with deep confident thrusts.

"Ohhhh yes!  I've wanted your big dick for so long, fuck me hard just like you fuck her... mmmmh."

"Damn girl, your pussy feels amazing.  You're such a tight little bitch... mmmmh, as long as your sister never finds out I'll pound you like this as much as you like..."

"Yes, pound me Brandon - I'm your slut now," groaned Mia as she shook and groaned... rubbing her clit and feeling her juices drip down. "Ohhh shittttt, I'm CUMMMING!" Mia was cumming hard and it felt amazing. Brandon's big dick reached her in places no other mans cock could.

She giggled as she squirted and shook, the rush of female orgasm making her shiver in pure pleasure. Mmmmh, she loved being a girl... she was so naughty and all the boys wanted her. It made her feel like a Goddess.

"You wanna cum inside me? I love being cream pied," she purred.

"No... I can't risk it, let me cum on your face you little bitch..." grunted Brandon. 

Mia was disapointed but she was sure eventually she'd get his cream inside her. She intended to fuck Brandon a lot more from now on - so there was no rush. "Mmmmh let me finish you off then," she purred, slipping Brandon out of her and sucking his dick enthusiastically till he nutted all over her pretty face.

Licking and slurping up all of his warm cum, Mia swallowed and felt satisfaction. She loved cum and making guys jizz all over her or in her. She had the record now for most blowjobs given at school... easily beating that loser Amber.

Mia used to be jealous of her sister but soon Amber would be jealous of her. Thanks to sharing the magic yoga mat - from now on Mia and Amber were going to be sharing everything... clothes, makeup and most importantly boys!
