A group of horny twinks, lured by the promise of cold hard cash, board a bus for a public, outdoor gay sex spectacle. The tennis instructor, a handsome, muscular man, is the bait. He flashes his throbbing cock to the eager, young guys, who respond with their own stiff erections. The scene escalates from playful groping to full-blown, passionate, raw sex as the bus cruises through the city, the guys' moans and grunts filling the air.
