As Karen felt Todd's body shift under her she also felt changes happening in her own body. The soft flesh of her breasts hardened and shrank back into her chest. Something similar was going on with her backside, which went from soft and curvy to hard, flat and muscular.
Karen felt the prickle of hair come in over her legs and arms, then all over her newly flat chest. Her shoulders were broadening and hips narrowing as her upper body took on a classic masculine V shape. Her legs and arms acquired an extra layer of hard muscle. Her hair was no longer dangling in front of her, but retreated into a short, masculine cut. Her pleasant female face was now a handsome male one.
As she moved closer to climax, her new penis seemed less and less like something added on, and more like a natural, integral part of her being. Sticking it into the gasping, moaning female beneath her seemed very natural. The new power she felt in her hips and butt was driving her penis deeper and more rhythmically into Todd. The fit between them felt just right. Karen realized she was no longer a woman, but a man taking and giving pleasure with a willing, enthusiastic female. His entire body seemed focused on the task of pouring his semen into a woman's female center.
Karen's mind changed to match his new form. He loved being male and fucking a beautiful woman. "Yes, yes, I'm a guy." he bellowed as he came inside Todd.
Carrie picked up the remote.
