A commuting OL and a pubescent student sharing a crowded bus. Every time the bus shakes, the plump butt wrapped in a tight skirt stimulates the student's crotch, causing a throbbing erection that the OL can feel. The excited woman's hand reaches for the cock and grabs it. The student, whose sexual desire cannot be quenched, also shifts his pantyhose to insert his cock without being noticed by other passengers!
