Staring blankly in the mirror, her mind rolled over and over, deciding how to react to the sudden development presented to her. As she struggled to find an emotion to latch on to, her hand drifted down and touched her new addition - the feeling was alien, but not unpleasant.
She made a decision - if she was stuck with this appendage, it's probably best to understand as much as she can about it.
Sitting on the end of her bed, she parted her legs. Her reflection in the mirror caught her eye - to her confused mind, she looked sexy as hell. Seeing her breasts and luscious long hair made her feel great. The alien growth on her crotch responded to the image, engorging itself and raising upwards, exposing her still present female parts.
The development helped her investigation - the penis did not really seem to extend beyond its original length now it was fully erect, but it did pull her foreskin back to reveal the glans. The solid girth of the penis highlighted where it was coming from, the top half of her labia parted as it emerged from where here clitoris once remained.
Parting her female sex, she could see the base of the penis joining the opening of her vagina - she would be urinating through her new organ.
Dirty thoughts entered her mind... Sex with boys, sex with girls, sex with herself!
She ran her finger down the penis, along the edge of her labia and teased herself. The feeling was great.
