Towering, tattooed hunk, bound and helpless, is subjected to a sadistic handjob. His tormentor, unseen but for gloved hands, grips his thick, throbbing cock, tugging it roughly. A zapper comes into play, delivering shocks to the bound man's sensitive flesh, making him jerk and groan. The unseen assailant works his meat, alternating between firm strokes and cruel zaps, driving him to the brink of orgasm before backing off, prolonging his agony.
