Brutal CBT Game

Description: I want to play a dangerous little game with you... are you up for it? it's going to be very difficult to endure. might even permanently alter you. here's the game: for every time i pump my cock, you have to smack your nuts. simple really. i even give you permission to jerk with me. i may allow you a short break... but it doesn't last long. now then my future eunuch, will you last?
