The target is a small, serious-looking girl in a school uniform. Surrounded by three giants, she completely shuts out the attention of the people around her! A triangle spot suddenly appears on a crowded train, and the men do whatever they want to her! They strip her naked, strip her naked, and use their thick fingers to give her every kind of pleasure! They take her to a sex room and thrust their thick penises into her, turning the innocent brat into a slut!
