A sissy in chastity, desperate for release, finds himself locked in a room with a relentless fuck machine. The machine's thick, pulsating dildo teases his caged cock, driving him wild. He's helpless, bound to the floor, as the machine mercilessly pounds his ass, bringing him close to orgasm but never letting him finish. Sweat drips, moans echo, as the machine's unyielding rhythm pushes him to the brink of madness.
