The bus lurches to a halt, and a fresh crop of passengers board, including a well-dressed businessman who does a double-take at the sight of the teen slut, her head bobbing in the stranger's lap. Intrigued, he sits nearby, adjusting his glasses to get a better view. She notices him, winks, and beckons him closer. He hesitates, then moves, feeling her small hand snake into his lap, unbuckling his belt. She takes him deep, her other hand fingering herself, moaning around his cock, putting on a show for the growing audience, the bus now a rolling orgy of lust and taboo.
