CLUB-571 - Saving a kidnapped teacher only to imprison and break her for a month

*Mayuri Teraoka looks slender I think he retired after releasing about 3 movies? From picking up a battered girl who was kidnapped and running away. There's nothing special about the female teacher, so I don't really understand it. He takes her home and attacks her while she puts him to sleep. I feel like keeping it as is. The room is decorated with idol costumes and has an otaku atmosphere. He puts on a collar and becomes like a slut, but I think it would have been better if he just did it all and let the pleasure fall.
