"I'm doing this to keep you quiet"...Right. The usual phrase.
Still, I wonder if there's more to come? The other girls didn't seem to have had a scene after all.
Wait what? The teacher recorded her having sex with the guy? So I'm guessing she could use it for reference to draw more eromanga? Then the other student girl members are fapping to it in the last page? lol. That's one awesome teacher.
