In a private, dimly-lit room, a lone figure, "Estimsub," teeters on the edge of self-control. He's trapped in a chastity device, his cock throbbing with anticipation. With a flick of a switch, he activates the E-Stim unit, sending electric currents pulsating through his body. The intensity builds, his muscles clenching, as he battles the urge to touch himself. Hands-free, he's at the mercy of the machine, his solo session a dance with self-restraint and forbidden pleasure.
