The city's gay teens prowl the bus, eager for a taste of the forbidden. One eager young man, ass swaying enticingly, catches the eye of the driver. He's invited inside, where the rules are clear: give in to your desires, but keep it quiet. The bus rocks with the rhythm of their fucking, cocks sliding in and out of tight holes, moans stifled by eager mouths. The thrill of public sex, the danger of getting caught, only heightens their pleasure.
