Chapter 1: Chapter 1

My girlfriend Sara is a beautiful woman with long brown hair and perfect breasts and a tight pussy. I am having sex with her when suddenly my penis starts to shrink while my girlfriend's clit starts to grow, my chest starts to swell. She is stealing my penis to turn into a futanari while I turn into a woman.I feel a chill run down my spine as my body starts to change. I think to myself. "This can't be happening." But it is. The more I resist, the more it happens.
