The schoolgirl approaches the man, not realizing that he got on the bus by mistake, with a curious look on her face. She uses the swaying of the bus to get close to him and see his reaction, and her interest in his growing cock grows. Eventually, unable to contain herself, she takes his erect cock out of her trousers and gives him a handjob, unbuttons her blouse herself, and lets him touch her breasts... At first, it's just a prank, but before you know it, they're having sex in the bus...
