“I guess these are it.” Hannah stood in her apartment's dining room alone, ignoring the small pile of junk mail for the box she held in her hand. She fished her keys out of her pocket and ran the rugged edge through the box's tape. “Yup. Looks like it is.” Inside the plain box sat an orange pill bottle and a folded leaflet with the dosage instructions on it.

Hannah had found herself in a rough spot financially these last few months. She had always had trouble keeping jobs so when she lost her last one it didn’t surprise her. What she was really worried about was finding a new job. She was awkward at interviews and with the job market being as atrocious as it's been she couldn’t get any application to stick despite her overabundance of experience. WIth her savings running low she needed some quick money to pay next month's rent and to her luck a local clinic was looking for volunteers for a drug study. She wasn’t a huge fan of subjecting herself to the study seeing as it was libido enhancers they were testing but with no other options in site she signed herself up.

Unbeknownst to Hannah, however, was that the pills she had been sent weren’t ever intended to reach her. A disgruntled employee upset over their stagnant pay, a clerical error in the clinic's inventory, and no one bothering to double check the bottles label before it was shipped out meant that Hannah had received a version of the drug that never made it past the testing phase. Every rat that was fed this early version of the libido enhancer eventually developed a libido stuck in overdrive and drastic swelling and a metamorphosis of their genitalia.

“Let’s see what this says.” She unfolded the instructions and gave them a quick once over, parsing the only information she needed to know. “Take one pill in the morning and one pill before heading to bed. Sounds easy enough.” She turned her head and read the clock on her oven, “9:29 AM. I guess I better get this going.” Hannah let out an exasperated sigh as she popped the lid off the bottle, shook a pill out onto her hand, and popped it in her mouth.

The next couple of hours were nothing special as the drug began dissolving and dispersing its payload into her bloodstream. Hannah stayed unaware of the side-effects that slowly cropped up in her own body. Her breathing gradually became heavier and irregular, minor heat flashes caused her to perspire through her clothes- It wasn’t until the middle of the day while she was watching TV that she couldn’t help but notice the drug's effects as her crotch grew warm and her groin began to softly throb. “Is this~? Are they testing aphrodisiacs?~” Hannah bit her bottom lip as she leaned back into her couch and snuck a hand underneath the band of her mildly soaked panties.

Idle strokes quickly turned into a full on masturbation session as she vigorously flicked her bean and massaged the inner walls of her vagina. “Hah~ Fuck!~ This is some~ nggh~ potent aphrodisiac!~” Hannah’s voice mewled past her lips as her right hand assaulted her quim and her left hand grabbed at her boob and rubbed its nipple underneath her thumb. No longer focusing on her show, her body tensed up as the pleasure built within her body and finally released. “Hah, hah~ Why do I still feel so~?” Hannah clenched her teeth as her hand continued barraging her pussy which despite just having received release still demanded more attention. Two, three, four times she came over the course of a handful of hours. Her hands were sore, on the verge of cramping, and her fingers were pruned from being soaked in her girl cum. Her apartment reeked with the scent of sex as she laid limp in her sweat soaked spot on the couch. Even with the subsiding desire within her body it still tingled due to the lingering remnants of the drugs. 

“Hah~ My clothes are soaked!~” Hannah panted. Her clothes clung to her skin, plastered there by her sweat and her vaginal discharge. She looped her thumb underneath the band of her panties and began shimmying them down her thighs and legs. Once her crotch was exposed she could see how puffy and swollen her outer labia had become, with a soft red blush bleeding through her fair skin but that’s not what she was shocked to see. Standing tall and proud, no longer hidden within her quim was her clitoris which stood erect and swollen now nearly the size of the tip of her pinky. “Fuck~ Is it supposed to be this intense?~” She forced herself up from the couch and made her way to the dining room, trying in vain to ignore the constant rhythmic throbbing in her groin. 

Hannah fished the booklet from the pills box and began rifling through the pages. “This can’t be right. They wouldn’t test something like this on people…” Her eyes shifted over the instructions going over them one more time. Take one pill in the morning and one at night, expect a rise in libido after taking pills, fill out the questionnaire and send it back to the clinic once the bottle is empty. Her eyes wandered to the pill bottle which was still brimming with doses and she could feel her heartbeat emanate throughout her drooling snatch. It wasn’t even close to when she should be taking her second dose but these pills gave her a euphoric high she had never felt before which she needed to feel again now. She dropped the booklet and darted her hand towards the pill bottle. Her hands shook in excitement as she fumbled to get the lid off but once she did she greedily poured four to five pills into the palm of her hand which she immediately tossed into her mouth.

Hannah practically skipped to her bedroom as an overwhelming sense of giddiness surged through her mind. Juices trickled down her bare thighs as the drugs coursing through her blood overlapped their addicting aphrodisiac like effect over one another. Her entire groin radiated an uncomfortable yet deeply pleasurable heat which demanded an attention which she would soon appease. She swung her bedroom door wide open causing it to slam against the wall as she practically leaped onto her bed. Her dominant hand began ravaging against the unquenchable itch within her pussy as her other hand grasped towards her end table and rummaged around its drawer. “Oh! It’s too much!~” Her voice was airy as she teased herself with her own words. Her arm trembled as it emerged from her end table holding a rather impressive and hefty dildo which she clutched to her chest. “That’ll do~” She removed her fingers from her twitching cunt which were slathered in a clear stringy goo and brought her toy down to her slit. She took a deep breath which she held before plunging the pink toy into her pink folds eliciting a moan from her as her back arched against her mattress. The rest of Hannah’s day was a bliss filled blur of animalistic masturbation as her lust continued to build and build with no end in sight. No matter how many times she made herself cum she couldn’t reach the precipice of her desires which were always out of her reach. Her entire groin burned and throbbed, matching pace with her heart rate which increased the more excited she made herself. After hours of countless orgasms and her body sore from her self pleasure marathon she passed out in her sweat and girl cum soaked bed with a slathered dildo discarded between her legs.

As Hannah peacefully slumbered the second side-effect of the drug she wasn’t intended to ever have reared its ugly head. Her already thumb sized clit twitched as the rest of her genitalia anatomy rearranged itself to match her ever climbing libido. Her ovaries dropped and were repurposed into testicles as her clit shaped itself into thick, slender dick. Her newly formed balls audibly churned as it went into overdrive producing semen which dripped from the tip of her cock and further stained her bedsheets.

“Hannah? Are you okay?” Eve, Hannah’s best friend, gently knocked on the front door to Hannah’s apartment. “I’m gonna let myself in!” She dug through her purse as she looked for the spare key her friend had given her. It wasn’t like Hannah to ignore her calls, especially when she was between jobs, which worried Eve. Her anxiety had gotten the better of her so she decided to go give her friend a visit to hopefully calm her fears. “There they are.” She pulled the keys from her purse and unlocked the door to Hannah’s apartment. She opened the door and poked her head inside. An overwhelming smell of sweat and foul stench hit her nose as she walked in. “Hannah?” Eve called out into the dark apartment but was only greeted with the faint noises of grunting coming from deeper inside. She let the door shut behind her as she slowly followed the noise. It sounded like a wild animal had found its way inside and it was rampaging about in frustration.

“Agh~ Oh~! It’s not enough I need~ I need more~!”

A raspy voice screamed out from Hannah’s bedroom, the same place the feral grunting and squealing was coming from. Eve swallowed the welt of fear that had settled in her throat and approached the bedroom door. The pungent, rotten scent was unbearably strong but she pushed through it and swung the door wide open. “Hannah!?” Sitting hunched over in her gaming chair was Hannah who was furiously stroking her erect penis with both hands in a death grip around her shaft. The floor was a room wide puddle of semen which was being fed a constant drip of cum from her friend's twitching cock.

“More, I need~ Eve?~” Hannah jolted at Eve’s voice, twisting her head suddenly to look in the shocked face of her childhood friend. Despite the deep embarrassment she felt with her friend witnessing her new body and shameless masturbation,  she couldn’t bring herself to cease jacking off. No, she couldn’t stop even if she wanted to. “Help me~ It’s too much Eve!~ Nngh~” She let out a deep grunt as she came, her cock spewing a voluminous and thick load of fresh cum which splattered against the ceiling and dripped back down to the ground. 

“Hannah…” Eve paused, disgusted by what was happening but worried about her friend. “What happened I- What do you need?”

Hannah panted, drool dribbling down her chin as she came too from her last orgasm. “It’s not enough~ I need release~” Her breathing became ragged and somehow heavier. “Help me Eve~”
