Groper Train - Women being kept in Captivity

Misa is a middle school teacher. She is beautiful and has a good reputation, but for some reason she has no luck with men. Every night, she masturbates on the train to work, fantasizing about being attacked by a bunch of perverts. One day, her fantasy becomes reality. Misa encounters a group of perverts on a crowded train and is surrounded by them. When she was too terrified to speak out, a man who looked like a businessman asked her, “Are you all right? He managed to save Misa from the trouble. Misa manages to escape thanks to him. The man calls himself Yamamoto, and she falls in love with him at first sight. She later starts dating him, but in fact Yamamoto is also a member of a group of molesters.
