I imagine it's because they figure he's gonna end up having to film her getting fucked by someone else. Now it's got a harem tag though, so I figure that's probably not the direction it's heading.Why do people keep bringing up NTR? Is it because she's an exhibitionist and people think she will get caught and blackmailed or something? Also, since the teachers were having an affair I don't feel bad for them as I did previously, still don't find ok the way he decided to expose them.
