In the throes of sexual frustration, a muscular, fit husband can't contain his desire. He grinds against a pillow, his hard cock aching for release. His moans fill the room as he imagines his wife with another man, his hips bucking wildly. He's a man on the edge, his body covered in a sheen of sweat. With a final, shuddering thrust, he cums, his load seeping into his jeans and boxers, a visible stain marking his frustrated, hands-free release.
