A mature man, alone in his dimly lit study, unbuttons his crisp dress shirt, revealing a silver-streaked chest. He lowers his zipper, releasing his substantial, veined cock. With a firm grip, he begins to stroke, his eyes closed, lost in a private fantasy. His pace quickens, breath hitching, as he edges closer to release. A bead of pre-cum glistens on his tip, slipping onto his thumb as he pumps faster, his ass clenching. With a low groan, he erupts, his load spilling onto the worn leather armchair.
