The man's grunts echo through the room as he picks up the pace, his cock throbbing in his hand. He twists his wrist on the upward stroke, adding friction, his balls tightening with each pass. He lets out a low growl, his abs clenching as he feels the familiar tingle at the base of his spine. With a final, powerful stroke, he comes, his cock pulsing as it shoots thick ropes of cum onto the floor, his body shaking with the force of his release.
