A straight, muscle-bound hunk, unaware of the watching eyes, pumps iron in the deserted gym. His t-shirt clings to his sweaty, flexing muscles, outlining every ridge and valley of his torso. He catches a glimpse of himself in the mirror, his reflection showing off his bulging biceps and powerful thighs. He can't help but stroke his growing erection, the tight fabric of his gym shorts doing little to hide his length. The voyeur, hidden in the shadows, watches in awe as the muscle stud worships his own body, his cock aching to join the action.
