King Calvin and King Mark, renowned for their kinky exploits, engage in a brutal cbt session. Calvin, dominant and smirking, attaches a heavy ball-chain to Mark's chastity device, pulling and tugging, causing the submissive to grimace in pain. Mark's bulge struggles against the cruel confinement, his balls aching from the relentless pressure. Calvin, ever the tease, runs his fingers along Mark's trapped cock, taunting him with denied pleasure.
