Your balls aren't good for anything other than for me to have fun with. And we're going to have some fun now, and it's going to be painful fun. You're going to follow along with me in slapping those disgusting balls. You're going to match me slap for slap. I'll be slapping my hand, and you'll be following me along and slapping your balls at the same time. When I speed up you speed up, when I slow down you slow down. You can wank at the same time and at the end I'll allow you to cum.
