You're always pumping your hand, aren't you and you're always allowed to cum! With me you get blue balls! I want you to stroke, slide, pumping your hand but always denied, I don't want you to cum, I want you to be denied and ultimately have blue balls. The only time you're allowed to stop pumping is when you think you're about to cum, do you understand? I'm going to make it so difficult for you, so hard! You're going to do exactly what I say, even when it hurts! Are you ready?
