The Substitution Stone: Karyn Wants to Use the Stone

"Wait a minute," Jon said, interrupting Karyn. "Don't you *want* to have sex with me?" "I'd rather not, but I don't have much of a choice. Now do I?" "What do you mean?" Karyn sighed. "You told me that I couldn't use the stone unless I fucked you. And I really want to use the stone. I have to do something about these breasts. They're killing me. So, if you don't mind. Can we get this over with? The faster we have sex, the faster I can use the stone." Jon was stunned. Why would he ever make any conditions like that? Karyn was his friend. If she wanted to use the stone, he'd just let her.
