Potion Mishap

Wait... which was mine again?

Early in the morning, Michael made his way downstairs to make some breakfast. He was surprised to find his roommate, Evan was already awake and standing in the kitchen.

"Good morning!" Evan said warmly as Michael entered the room.

"'Morning," Michael yawned back to his roommate, still feeling very sleepy.

"You look pretty tired. Here, I made some coffee," Evan said, eagerly offering him a mug. 

Sluggishly taking the cup of coffee, Michael thanked his roommate and took a sip of the hot drink. As Evan sipped the rest of his own coffee, he watched his roommate intently, like he was waiting for something to happen. But that something never came. Instead, Evan was surprised by a sudden, intense grumbling in his gut. Hunching over slightly, his eyes went wide with panic.

"You alright...?" Michael asked, noticing his roommate's distress.

"...oh fuck..." was all Evan could say before he was overwhelmed by a surge of intense energy. Michael watched helplessly as his roommate suddenly began transforming right before his eyes. 

Not only did Evan shrink by several inches, but his body became visibly slimmer. His pajama pants and boxers easily slid off his much more slender waist and left him completely naked. All body hair except for his pubes vanished while the hair on his head lengthened down his shoulders. The rough, masculine features of his face and body gave way to supple softness as his skin became silky smooth. Parts of his bone structure were modified, leaving him with significantly wider hips and a more slender torso―giving him a perfect hourglass figure. Excess fat redistributed itself, particularly to his lower body and chest where a pair of perky breasts swelled to complement his curvaceous bottom. Lastly, between his legs, his manhood shriveled and quickly retracted into his groin where the soft folds of his new womanhood blossomed in its place. The transformation happened faster than Evan could even react. Standing in the kitchen with the coffee cup still in his hand, he found himself suddenly very nude and very female.

"Holy shit!" Michael finally said, breaking his stunned silence. "What the hell just happened?!" 

Evan let out a long, agitated sigh. "I really fucked up," he (she?) replied in a cute, girly voice. An annoyed expression was painted on the new girl's pretty face as she glared at her roommate. "I drank from the wrong cup."

Michael had a confused look on his face. "You tried to... poison me??" he said, looking down at the warm mug in his hands and slowly setting it down. 

"No, dumbass, it's not fucking poison. I was a potion that was supposed to... well..." she said, gesturing at her beautiful female form. "But I guess I mixed up which mug I poured it into."

Gears were turning in Michael's head. 

"So, you were trying to transform me... into a chick... with a spiked coffee?" he asked.

"Check out the big brain on Mike!" Evan sarcastically remarked. 

"But... why?" asked Michael.

Evan sighed again as she absentmindedly tied her hair up into a bun, looking like she'd done it countless times before.

"You're a really annoying roommate, Mike. Cute, but annoying," Evan said, visibly confused by her choice of vocabulary. "You never clean up after yourself, you're way too loud, you steal every girl I have a chance with... This potion I brewed up was supposed to take care of that." 

"...by turning me into a girl?" Michael asked, still confused.

"No, silly. By turning you into my perfect boyfr- girlfriend," Evan said, closing her eyes and shaking her head in frustration. When she opened her eyes again, it appeared as if she'd made a distressing realization. 

"Oh shit..." she said before rushing into the kitchen. 

"Uhh... why are you acting so strange?" asked Michael.

"The mental changes are starting, that's how the potion works," Evan explained as she frantically searched through cabinets. "On top of giving me this tight, sexy body, it's messing with my head and turning me into a horny little slut."

While Evan began sauntering about the kitchen grabbing all sorts of ingredients, her voluptuous body jiggled and bounced in all the right places. Michael became transfixed on the girl's sexy figure, which was only accentuated in the warm morning light coming from the windows.

"So... can you stop your potion from turning you into a... 'slut'...?" he asked, trying to distract himself from his roommate's new assets.

"Of course, cutie. I'm fixing together another potion that should reverse the effects," Evan replied. 

As Evan frantically brewed her new potion, she was bent over the counter and unwittingly providing Michael with a perfect view of her shapely ass and the neatly-trimmed pussy nestled between her creamy thighs. The alluring sight was impossible to ignore and Michael could feel his penis responding accordingly.

"Annnnd done!" Evan said in a bubbly voice as she turned around, holding a fresh cup of coffee in her dainty hands.  

But then she just stood there, her ass squished against the cold granite as she leaned on the countertop. She was looking at Michael's body and was clearly very distracted. Eventually, her gaze met his, and Michael could see a deep desire in her eyes. 

"A-Aren't you going to drink your... potion?" Michael asked nervously. 

"Well, I was..." Evan replied in a suddenly very sultry voice. "But I didn't expect the urges to be this strong..." 

Her eyes fell on Michael's crotch where the impression of his erect cock was clearly visible through his sweatpants.

"I know I should drink this potion," she continued, "but if I do, then I won't get to feel that inside me..."

Michael gulped, feeling his cock stiffen even harder as Evan began unconsciously rubbing her wet thighs together.

Evan gently set the mug down. She bit her plump lip and slowly began walking towards her roommate, looking unbearably hot and flustered.

"Evan... this is really weird..." Michael said, unable to take his eyes off the approaching woman's swaying hips and jiggling breasts. 

She pressed her body on his, pinning him against the countertop. 

"Shhh," she said while gently tracing her fingers over Michael's diamond-hard cock. "Call me Evelyn."

"E-Evelyn-... I do― ohh~," Michael cooed as she slid a hand into his pants and started stroking.

"Mmm baby~... I need you inside me so bad. Pleeease? I'm so fucking horny," she begged, slipping his sweatpants down while expertly working his cock. 

It didn't take much for Evelyn to convince Michael to do what he'd wanted to do for several minutes already. He easily moved the dainty girl off of himself and positioned her against the countertop. Bending her over the cold granite, he grabbed his cock and placed it between her creamy thighs. 

The moment Evelyn felt the rigid manhood slide against her drooling cunt, she squealed with pleasure and excitement. Her warm wetness quickly coated Michael's shaft as he rubbed it against her tender folds. Finally, with both of them desperately wanting it, Michael slowly thrust forward and his cock easily slid deep inside Evelyn's tight, virgin pussy. 

The two lovers moaned loudly as they fucked each other's brains out. Michael grabbed Evelyn's hot body with his strong arms, pulling her against him and holding her close as her ass bounced with every thrust he gave her. She felt far better than any woman he'd been with before. He could feel an orgasm building, and he wasn't planning on pulling out.

Evelyn could also feel an orgasm building―her first female orgasm. Deep down, she knew that she needed to stop. An orgasm in her new body would seal the magic, leaving her stuck as a horny slut for the rest of her life. But the more she thought about it, the nicer that idea sounded. If being a girl felt this good, then Evelyn was looking forward to many more orgasms as Michael's nympho girlfriend.
