He didn't want to become a girl

"No, I don't want to." John protested and sat up. The long blond hair of his wig fell over his shoulders and tickled his face, neck and shoulders. He also felt the dangling of the earrings on his ears and neck. "I don't want to become a girl. I have no problem to dress and act like one for sex. But I don't want to become one."

"But you would make such a sexy girl." Dr. Valentine tried to convince him. "Big bouncy tits, full cocksucking lips, a big fuckable ass. All the things you like about a girl with a cock could be yours, and mine to use." John noticed Dr. Valentine growing an erection as she imagined his new looks.
