The Rock, a charismatic hitchhiker, spots a chance ride in a passing bus filled with horny gay passengers. With a wink and a smile, he propositions the driver for a lift, unaware of the carnal games at play. Once on board, the Rock is subjected to a gauntlet of sexual advances, from nipple licking to full-blown fucking. He's a good sport, enjoying the attention as much as the other passengers, turning the bus into a mobile orgy of sweaty, naked men in heat.
