Kelly was rinsing out her mouth when Gina asked the question. When she was finished she turned to her friend with a big grin. "What do we do next?" she repeated. "What we do next is that I fuck your hairy, muscular ass with my big, hard cock. Any questions?"
Gina trembled with anticipation. "Can I get rid of these tits now?" she asked.
Kelly shook her head. "Not yet. Me next. I wish I had a cock just like Gina's, only about half an inch longer and proportionately bigger around." She felt her vagina disappear, her labia form into a scrotum, her ovaries, now testicles, descend into their new home, and her clitoris grow into a huge penis, fully erect. Gina licked her lips.
"I wish" Kelly continued "that Gina's lower body become completely that of a young, muscular man who works out regularly."
