Home brew

As she squatted down to pick up a bottle from the bottom shelf, Mikayla felt her perfect bare buttocks stretch apart under her tiny skirt, and she grinned to herself, remembering how good it had felt to get reamed in her ass last night.

She had loved the feeling of her rear being completely filled, her tight asshole stretched out by a hard eight inch cock as she bent over on all fours in a mesh body-stocking on a random dudes dorm bed, and the fit guy she had been flirting with all night at the student bar grunted with satisfaction as he bottomed out inside her and hot wet sex slaps filled the air. 

The tube of lube had rolled on the bed next to them, her lovers glistening oiled up cock easily pistoning in and out of her tight virgin hole as she spread her butt cheeks wide and moaned like a dirty slut. It had been glorious to finally lose her anal virginity... and even better knowing the guys girlfriend was back at the bar, wondering where her boy had got to.

They had fucked for hours, the guys hands in her hair and sweat dripping off their bodies as he pumped her hard - their fucking alternating between her pussy and her ass, with the occasional blowjob between in order to suck down his warm cum and get him ready for another round.

Mikayla grinned to herself feeling her nipples get hard at the memories of last night. She had loved having both holes filled... mmmmmh what would it feel like to get her pussy and her ass filled at the same time? She imagined two cocks filling her up and how hot it would feel and felt herself get wet at the thought. Yes... being rammed full of bad boy cock would feel amazing.

"Nooo... we never used to be this fucking slutty... something is wrong," 

Mikayla rolled her eyes as what she called her 'Michael voice' intruded on her horny thoughts. God he was such a bore wasn't she rid of him yet? 

Picking up the seemingly innocent household goods she needed, she whistled happily as she placed them into a basket and continued to ignore her male self's pleading voice.

"Mikayla... please... there's something wrong with this new Elixir we've been using.  It's made us into a complete whore. We never used to be this slutty, we never used to be this obssessed with sex. We've become a spoiled bitch."

Mikayala wanted to laugh hysterically. What rubbish was Michael spouting? She had never felt better, in fact it felt so glorious to be an unihibited slut. She felt so fucking horny and hot all the time now, dressing like a flirty spoiled slut and partying like a rich bitch was such fun.

"The substitute chemicals we are using are impure, they have made us into a total nympho - we have to stop!"

Mikayala giggled as she added more things to the trolley.  Now she understood what was happening to make her feel so good. Michael was so smart... the son of a famous scientist would be of course... and his intelligence was also her intelligence.  

It had been Michael who had found the lost family formula tucked away in a book, allowing him to become a girl whenever he wanted.  Making and taking the Elixir had freed his female persona and the shy boy had enjoyed learning what life was like as a cute girl. Mikayla had been sweet and innocent then, nothing like the slutty bitch she had become recently.  She liked the new her a lot better...

When Michael had started university he had lost access to his fathers home chemistry station with its pure, high quaility chemicals.  The Elixir 'home-brew' he had invented, so he could continue to spend time as a girl, had seemed fine at first, but the super slutty effects were obviously being caused by this new brew's unusual ingredients which included all manner of regular household goods and discount chemicals. 

Paying for her shopping, Mikayla walked back to her dorm, thrilling at the hot stares of all the boys as she passed them.  They all wanted her and that made her hot for cock... she would have to be patient though, she had important things to do before she got distracted with fucking.

Even though the dorms were meant to be single sex, Michael's dorm buddies didn't seem to mind her staying at his place, not since she had fucked them all. Being a bad girl made life so easy, boys would do anything for a blowjob and they all thought Michael was a total stud for pulling a hottie like her.  How funny that when she was male she got to listen to them tell Michael stories about how tight her pussy was and what a good ride she was. 

Unpacking her shopping, Mikayla prepared an area on the desk and started to brew up. "No! Wh...what are you doing?" groaned Michael as she walked over to his sink and began pouring away the few pure chemicals he still had left from home.

"I think we should improve the home brew even further," she smirked. "Lets see if using even more substitute chemicals makes me even hotter and naughtier."

"No! Why would you do that to us?"

Grabbing a suction dildo from a drawer, Mikayla stuck it to her chair and squeezing lube from a tube began spreading it over the veiny rubber cock.

"Wh...what are you doing?"

"I know you want me to be an even bigger slut too... you love being bad. Being a hot girl satisfies you in ways that nothing else can. I want to hear you say it. I want you to beg to be sluttier."

Hiking up her skirt and sliding down her tiny thong, Mikayla straddled the dong and slowly lowered herself onto it.  She moaned as she felt it spread her ass wide and she began to slowly bounce up and down on it, riding it deep like the cock she had enjoyed last night.

The sensations were amazing, especially when she rubbed her clit at the same time.  She could feel a squirting orgasm coming on for sure this time.  

"Mmmh.. my dorm mates could walk in at anytime... we shouldn't be doing this..."

Miklaya sighed happily and hiked up her vest top to free her tits. "That would be wonderful... just think how good another cock or two would feel in here." Her eyes rolled up and she squealed as she began to cum, the thought of it tipping her over the edge and her pussy spraying wet juices over the chair and even onto the desk. 

"Ohhhhhh shit... you're such a slut... I can't fight you anymore... I love how this feels. I'll help you do whatever you need!"

Her orgasm still subsiding, Mikayla smiled triumphantly as she slid the dildo out of her ass and licked it with her hot pink tongue. Being slutty was so yummy. Grabbing a jewelled silver butt plug, she slid it into her rear, loving the feeling of being plugged up and filled all the time.

Turning back to her work she began to make her new and improved Elixir Home-Brew, guided by her male half's enslaved and eager intelligence. She couldn't wait to try it out and see how much sluttier it made her. That threesome was definitely on the cards now...
