In this adult teacher-student role-play, a male student dreads his daily hour-long ride on a packed train. Everything changes when the crowd pushes him against Ms. Mori from his school. Her tight-skirted ass brushes his crotch with the movement of the train, giving him an obvious erection. Instead of rejecting him, she smiles gently, beginning a secret relationship in which she discreetly lets him touch her and creampie her during their commute.
