A dominant mistress commands her submissive slave to stand before her, hands bound behind his back. She circles him, her heels clicking on the cold floor, eyes locked onto his crotch. "You know what I want," she purrs, a sadistic smile playing on her lips. The slave nods, swallowing hard. She kicks off her heels, revealing her bare, pedicured feet. She begins to stomp, her soles connecting with his balls, each impact echoing through the room. The slave groans, his body trembling, but she continues, her footwork precise, each step a testament to her power over him.
