Marco Duran, a strapping soldier with a sleeve of tattoos, stands at attention, but not for duty. His uniform does little to conceal his bulging muscles or the growing tent in his pants. He casually unbuttons his shirt, revealing his chiseled chest and abs, before turning his attention to his crotch. With a hungry groan, he pulls out his massive cock, already throbbing and ready for action. He takes his time, slowly stroking his big, veiny dick, his hand moving in long, fluid motions. His uniform, once crisp and neat, begins to rumple as his body responds to his touch.
