King Calvin and King Mark, two dominant jocks, engage in a brutal game of ball-busting. Calvin, the sadistic one, kicks Mark's bare nuts with full force, making him grunt and groan in pain. Mark, the submissive, takes it like a champ, his cock hardening with each kick. They switch roles, Mark's powerful kicks causing Calvin to cry out, but neither stops until their balls are thoroughly bruised and their cocks aching for release.
