A strapping, athletic construction worker finds himself alone in the site's makeshift dressing room, his uniform laid out before him. He starts to dress, but his wandering hands can't help but explore his muscular body. He runs a finger along his jockstrap, tracing the outline of his hardening cock. Unable to resist, he slips off the jockstrap and his boxers, revealing his thick, veiny member. He strokes it slowly, his other hand reaching around to tease his ass. He spits into his palm, lubing up his finger and pushing it into his tight hole. He moans, increasing his strokes, his body tensing as he approaches orgasm. With a final thrust, he comes, his cum shooting out, coating his hand and dripping onto the floor. He cleans up, his body still humming with pleasure as he steps back into his day, his secret little pleasure session tucked away.
