I'm Emiri Momoka, homeroom teacher of Class 5, Grade 3 at Private Makujyuu Academy. I strive hard to be a good role model for my students at school, but in reality, I have an extremely strong sex drive—possibly even a full-blown sex addiction. It's been two years since I last had a boyfriend, I can't find romance at work, and I can't get involved with any students. With no other outlet, I've fallen into a daily routine of obsessive, animalistic masturbation—the only thing that soothes me.
