In this intense solo session, a chastised man, driven mad by his constraints, takes matters into his own hands. His fist flies up and down his rigid shaft, the sound of his wet, desperate strokes filling the room. His balls tighten, his breath hitches, and with a final, powerful thrust, he unleashes a torrent of cum. It splashes against the walls, drips down his trembling body, and coats his fingers, which he hungrily sucks clean.
