A stern femdom, clad in leather, takes center stage, her heels clicking on the cold floor. Her submissive kneels before her, eyes downcast. She grabs his chin, forcing him to look up. "You've been a bad boy," she purrs, her voice laced with disdain. She places her patent leather heel on his crotch, applying pressure. He winces, but she doesn't relent. She grinds her heel, twisting and squeezing his 'pathetic little nuts,' as she promised. His face contorts in pain, but he dares not move.
