Groper Train: Let Me Massage You from Behind (1992)
Director: Satoru Kobayashi
Office ladies Kiriko and Mayumi are working part-time handing out flyers for an erotic massage parlor. They do it on a packed commuter train. They slip a flyer into the pocket of a frustrated man who molested them. Tonight, he reaches out to Kiriko's plump ass right away, and he starts massaging her ass from behind.
