Let’s play a little game: I want to bust your nuts, and you want to jerk off. That’s fine. Let’s see how much you can take and if you get to cum at all. I want you to sit with your legs spread in a hard chair, and I want you to have a shoelace from one of your shoes. You’ll tie up your nuts tight for me and punch yourself in the balls! Is it going to hurt too much, or are you going to have to play again to get the chance to cum?
