On the Baitbus, anything goes. A group of young, straight-looking college studs find themselves on a bus with two siblings, one gay and one curious. The gay brother can't keep his hands off the young, fit jocks, and the sister can't take her eyes off the public display of gay sex unfolding before her. The bus becomes a reality show of sorts, with the brother fucking and sucking his way through the passengers, while the sister watches, entranced and turned on by the taboo scene.
