King Calvin, the expert gay dom, has King Mark in his dungeon, ready for a brutal cbt session. Mark's feet are bound, his body suspended, his cock and balls exposed. Calvin, in full dom attire, approaches, his eyes gleaming with sadistic intent. He runs a ball gag over Mark's lips before pushing it in, muffling Mark's cries. Calvin's cruel, gloved hands caress Mark's balls, then suddenly, painfully squeeze, making Mark writhe. Calvin chuckles, enjoying his sub's suffering, as he continues his merciless ballbusting, pushing Mark to his limits.
