The Irish muscle twink, fresh-faced and naive, boards the bus, unaware of the horny gay men around him. As the bus driver, a twink himself, starts the engine, the game begins. The Irish lad's innocent chat with the driver soon turns flirty, the driver's hands wandering, his bulge growing. The other passengers, a mix of twinks and jocks, watch, their own erections straining against their jeans. As the bus rolls on, the Irish muscle twink's world is about to open up to the raw, public, and horny gay reality of the Bait Bus.
