So I've been going through the game and trying to get all the CG's, at least, now that I've seen all the endings I actually wanted to see, but I noticed in a CG collection on E-Hentai that I seem to be missing a set, and no matter what I do I can't seem to trigger it. It's an H-scene between Takuya and Terada the gym teacher. I got the one with Maiko and Terada, but not Takuya and Terada. Can anyone help me figure out how to get that scene?
