In this adult commuter-student role-play, Miyuu’s cute face and huge breasts make her a daily target for molestation on the train. One day a different pair of hands slips under her shirt and panties, using techniques she has never felt before and making her body twitch helplessly. Unable to forget his touch, she starts craving it again and willingly entrusts her body to the molester—even in public and despite having a boyfriend she loves. The story follows the busty beauty as she becomes increasingly addicted to his technique.
