Amorous Professor Cherry

I'm Kouta Koikawa, and I'm having a problem with my studies. The problem is my social studies professor, Chieri Hase. From the day she started teaching here I haven't been able to keep my eyes off her! She's a rookie teacher, but I'm captivated by every movement of her beautiful body. I can't work up the nerve to confess my feelings - I'm her student, after all, and I'm sure she wouldn't find this sort of forbidden love to be proper... until one day when fate brings us together in an encounter that changes our lives forever.
