A strapping, straight construction worker, his muscles glistening with sweat, takes a break from his labor, unaware of the raunchy surprise waiting. A fellow worker, equally beefed up and hungry, approaches, his eyes locked onto the straight man's ass. He rubs his hardening cock against the unsuspecting straight man, who, initially shocked, soon surrenders to the throbbing pleasure. They fuck raw and hard against the construction site's equipment, oblivious to the potential audience, their grunts echoing through the empty lot.
