After some time

"What happened?" John asked not remembering much since he began sucking on Dr. Valentine's cock.

"You were wonderful." Dr. Valentine replied with a big smile. "For your first time sucking a cock you were not bad. And how you handled getting fucked by my huge she-cock, clearly made for more."

"What is this?" John had noticed the glasses on his nose and took them off. "Glasses?"

"Just some accessory for the looks."

John put his hand to his ear, where he felt something tickling as he took off the glasses. It was silky, thin and a lot of it. He pulled it into his focus and saw long, wavy blond hair. At the same time he felt something dangling against his neck. He felt for it too and noticed it coming from long dangling earrings hanging on his ears. "I have long blond hair and earrings." John noted.

"Yes, you have." Dr. Valentine said proud of her work. "But there is more to it. Look down."

John looked down and saw two small round moans resting on his chest in the wide cleavage of a black dress or top. They clearly didn't belong to his body but were breastforms. But that was enough for John to realize what he looked like. "Oh my god, you have dressed my up like a girl."

"Not just any girl. I have turned you into a sexy crossdresser secretary." Dr. Valentine said as she helped the lightly shocked John up and dragged him in front of a body-length mirror. There she put the glasses back on him. "Aren't you making a sexy secretary?"

John looked into the mirror and saw his changed reflection, the reflection of a boy crossdressing as a sexy blond secretary checking out one of her new breasts with her hand.
