Kneeling on the cold, hard floor, the bound sub awaits his mistress's command. She enters, her heels clicking ominously, and orders him to pleasure himself. He obeys, his hand moving furiously over his cock, eyes locked onto the camera. As he nears climax, she demands he taste his sin, pushing his face down into the puddle of cum he's just created. He gags, but she's relentless, forcing him to clean every last drop, his body quivering with a mix of humiliation and pleasure.
