Exhausted by her sub's relentless teasing, a stern mistress decides to take control. She secures him in a custom-made bondage chair, his aching cock confined in a tight chastity device. With a sadistic gleam in her eye, she mounts a strobing, pulsating toy onto his chest, ensuring it's positioned directly over his caged manhood. As the toy buzzes to life, she forces her bound plaything to watch her masturbate, her fingers dancing over her clit while he groans in futile, frustrated arousal.
