Hana is a beautiful adult college student and trainee teacher with the polished look of a TV anchor, but little sexual experience. On her commute to school, a groper touches her ass and pussy for the first time. Surrounded by passengers, she cannot resist his skilled fingers and writhes into orgasm. Despite pursuing a teaching career and knowing students or teachers may be nearby, she becomes hooked on the forbidden pleasure, waits for him with a wet pussy and eventually climaxes so hard that she loses bladder control on the train.
