In a dimly lit dungeon, a twink slave awaits his master's next command. The master, a muscular, tattooed man, smirks as he approaches, his eyes locked onto the twink's small, smooth balls. He grabs them roughly, causing the twink to gasp and writhe. The master's grip tightens, his fingers kneading and crushing the sensitive orbs, drawing out cries of agony from the twink, who can't help but feel his cock pulse with forbidden excitement.
