In this intense gay BDSM scene, a muscular slave submits to his dominant partner, who secures a collar around his testicles, turning him into a human puppy. The dom leads his sub, attached by a leash, through a series of commands, pushing his boundaries and exploiting his sensitive balls. The sub groans in pleasure and pain, his cock rock-hard, as he's made to perform humiliating acts, his testicles aching from the tight collar.
