The girl in my class who doesn't attend school, 'Momoka.' Since she hardly ever comes to school, I went to visit her home directly, but honestly, I don't even remember what she looks like. Somehow, I thought she was probably the type to wear glasses and be a quiet kid... I was thinking that. When I rang the intercom, a beautiful woman appeared at the entrance. 'Is this her sister?' I was thinking when suddenly she turned out to be incredibly skilled in seduction, and before I knew it, I had been drawn in and ended up having sex with her. 'W-what if Momoka sees me like this...' 'Huh? But I am Momoka.' As a teacher, I unknowingly broke the taboo of having sex with a student. I'm being blackmailed with a video, what's going to happen to my life from now on...
