"I've never done anything like this before," admits one of the strapping young men, his eyes darting nervously around the bus. His companion, equally inexperienced but driven by curiosity and a growing erection, whispers, "Let's give it a try." They start slowly, tentatively, but as the bus winds through the city, their excitement grows. Their hands explore each other's bodies, their breaths hitching as they discover the pleasure of another man's touch. The camera captures their raw, uninhibited delight, the bus becoming a mobile den of gay exploration.
