Tiffany grabbed the 'Recycle' vial and gulped it down. What the heck, she had nothing to lose in her mind. As the fluid trickled down her throat, she braced herself for the worst. A wave of warmth emanated from her middle, moving down her limbs and through her head...
An aching pain in her lower body forced her to lean over the table - it started small, like everything seemed to do with this stuff, but then a cold feeling happened across her groin. She lowered her hand down and her heart skipped a beat - her sex was returning. Tiffany sat down and watched her groin bloom like a flower - first her slit slowly 'unzipped' itself, rising up her mound to meet her pubic hair, then her labia bloomed out. As it slowed down, a small lump formed at the top before with a sensual pop, her clitoris regrew.
"Back to normal then?" asked Katie, seemingly disappointed.
"Yes, thank god. Lets sort you out and get out of here!"
Tiffany span around to grab the vial... There was the sound of glass rolling, then smashing.
"What the... Oh god, NO. Katie, that was the formula I just used..." pined Tiffany, looking at her friend. Katie stood there, a single tear running down her face.
