In a dimly lit dungeon, Mistress commands her slave to his knees. She wears high heels, perfect for her ball-busting mission. The slave's eyes water as she stomps and grinds her heel onto his vulnerable sack, turning it a nasty shade of purple. He whimpers, but she spits, "You wanted this, boy." She continues her brutal dance, using her foot to kick and push his balls, making him cry out. Sweat drips down his face as he struggles to maintain his position, pleasing his cruel mistress.
