Emi Tooda, a married woman, hasn't ridden a train in a long time and unluckily boards a car filled with molesters. She never imagined something like this could happen to her. However, her unsuspecting appearance quickly draws the attention of a groping pervert, who boldly reaches out and begins sliding his hands over her pantyhose, groping her crotch. As he varies the pressure, rubbing her with increasing intensity, Emi's body gradually heats up, her pussy dripping with arousal. The situation spirals beyond her expectations, driving her deeper into unexpected pleasure.
