Mistress Lexi likes her slaves extremely obedient, no man is more obedient then when a woman is holding an electrifying power box attached to his balls. She knows how sensitive a mans balls are and preys on his male weakness. She turns up the dial on the electric humbler and watches him crawl around with his balls pulled behind his legs shaking in pain. She even slaps his balls and crushes them under her stiletto all while she continuously fries his nuts.
