Let's do a CBT jerk off session. Get yourself a handful of clothes pins for this task, I want you pinching the skin on your balls while you jerk off. I'm not sure how many you can take, we should test it. Just keep adding pins, over and over. You'd be amazed how many you can fit. If you have clips leftover, keep adding them before you cum! Real men can handle covering their scrotum in clothes pins, will you impress Me today?
