Unbeknownst to Samantha, Karyn never gave him back the stone. She decided to make another wish. "I wish that, until I wish otherwise, Samantha would gradually decide that he likes wearing girl's clothes and would continue wearing them even after I 'forgive' him."
The stone flashed, telling Karyn that her wish had been granted.
Meanwhile, Samantha took off Karyn's clothes and put on one of her nightdresses (again, something girly that Karyn would never wear). He thought it actually felt kind of sexy, especailly the way if felt against his bare ass. Maybe this isn't so bad after all, he thought. Maybe I could keep doing this after Karyn forgives me, at least in secret.
As he fell asleap, he wondered what new punishments Karyn would come up with the next day.
