In a sheer, transparent pair of boxers, a muscular man finds himself unable to resist the urge to pleasure himself. His cock, already semi-hard, grows fully erect as he begins to stroke it, the outline of his impressive length clearly visible through the thin fabric. As his pleasure mounts, he pushes his boxers down, allowing his cock to spring free. With a series of quick, jerky motions, he brings himself to the brink of orgasm, his body tensing as he cums, his semen shooting out in thick, ropey streams, leaving him shaking and breathless.
