Mistress Nikki is laying on the floor in her sexy white bikini. Her slave stands over her. Does he have power over her? Nope. Nikki wants to do some leg presses and she is going to crush her slave's nuts in the meantime. She puts both feet on his balls and lifts him high in the air. His balls smashed between her feet and his own weight. The slave is in so much pain he can barely stand it. Nikki just laughs and continues her exercises.
