In the heart of the city, a gay bait bus rolls in, filled with horny twinks and eager tops. Among them, a curious straight guy can't help but feel the electric tension. A smooth, muscled twink takes the seat beside him, his ass rubbing against the guy's arm. The twink's hand slowly inches closer, and soon enough, the straight guy's cock is throbbing in his pants. The twink whips out his own hardening dick, and the straight guy, unable to resist the temptation, follows suit, leading to a hot, public gay encounter on the moving bus.
