In the heat of the day, a Marine and a young twink find themselves alone in a bustling city square. The Marine, a mountain of muscle, can't resist the temptation of the twink's lithe body. He grabs the young man, pushing him against a wall, and begins to grind his massive, jean-clad ass against the twink's crotch. The twink, excited and nervous, feels the Marine's hard cock pressing against him as they dry hump in public, the risk of being caught only heightening their arousal.
