A stern mistress, clad in leather, commands her submissive to kneel before her. She begins a relentless assault, kicking his balls with the sharp heel of her boot. Each impact sends a jolt of pain through him, but he endures, knowing this is her will. She switches to her bare feet, her toes digging into his sensitive flesh, making him gasp and moan. The mistress, empowered by his pain, continues her merciless ball-busting.
