Beg her to change you back
From Create Your Own Story
"What, when you're so good at being on the receiving end?" Penny says. "I don't think so."
She fucks you several more times, unloading so much sperm inside you that it dribbles down your legs. You learn just how overwhelming multiple orgasms can be. Afterwards, Penny cleans you up with her tongue and her penis turns back into a magic wand. She dresses you up in a duplicate of her costume and takes you back to her hotel with her. You spend the night together in a lesbian sixty-nine.
You become her stage assistant. By day, she amazes audiences with the things she pulls out of your moist snatch and at night she puts her wand in her pussy, makes it into a penis, and pumps sperm into your mouth, your ass and your pussy. After a while, you forget that you were ever anything other than her fuck toy.
The End.
