Deep in the woods, a lone runner, decked out in sleek, black running shorts and a matching nylon singlet, can't fight the urge any longer. His pulsating cock, constrained by the tight lycra, demands release. He pushes his shorts down, revealing his hard, throbbing penis. The cool forest air kisses his heated skin as he begins to pleasure himself, his hand sliding up and down his length with increasing urgency. The crinkle of his pantys and the soft rustle of leaves fill his ears as he races towards his climax.
