GMJK-023 Mucha-niku is a chubby girl who spills out of her clothes, has a fetish for tight suits. She boards the train expecting to be assaulted; in reality, she's a chubby OL with a masochistic streak, Hoshinatsu Naina.

She's an OL who commutes by train wearing a tight suit, always feeling like someone is watching her. Her heart races as she gets wet down there every day. That day too, men gathered around her. One took a photo up her skirt with his smartphone, another groped her ass. From that point on, the lewd acts escalated. She sought help from female passengers, but they turned a blind eye… Her clothes were stripped off, and she endured a miserable ordeal. However, she came back to the same carriage at the same time the next day. She's quite into this kind of thing. The men had their way with her. Good job before work.
