I really get excited when making a slave cock suffer. I love to clamp that foreskin. I make sure to attach the painful clamps right next to each other. I want to fit as many as possible on that cock and create the most amount of pain as possible for My suffering slave. Not only have I tied his balls tightly, but I also grab and squeeze them, twisting them this way then that, all whilst tormenting that clamped cock. If he's a lucky slave, I will pull back that painfully clamped foreskin, expose his sensitive cock head and give it nice, hard slap!
