A defiant slave meets his match in a stern mistress, who takes him in hand for a brutal lesson in obedience. Gagged and bound, he's made to endure intense, prolonged torment, his body writhing as electric currents course through him. The mistress, clad in leather and latex, toys with him mercilessly, pushing him to the brink of endurance. Yet, even as he begs for mercy, his cock betrays his defiance, standing stiff and aching for release.
