At midnight, a man on the last train catches the eye of a busty high school girl. The man is fixated on the panty shot peeking out from between her taut thighs, and although she is confused by the sexual gaze of a man she doesn't know, her mischievous Kokoro gradually becomes ignited! While worrying about being seen by others, she gives him a blowjob on the train, a close-up kiss with her plump body, a motherly breastfeeding handjob, and a masturbation show, and the two escalate things to the point of forbidden sex on the train! He takes the high school girl home, excited by a pressure titjob, and has plenty of fun with her voluptuous body!
