One day, a Japanese boy named Kazuhira decided to do the first manly thing in his life - confess his feelings to a girl he knew. Unfortunately, the girl took it as "neither hot nor cold," and the guy was left with his nose... One day, typing in the school library of books, he heard a noise, and saw something that scared him a lot, but also excited him. The very same girl was in a passionate embrace and entwined with the school gym teacher. From that moment on, Kazuhira realized that this girl was an inveterate nymphomaniac and unable to keep her hormones under control. The amount of sexual intercourse she had was off the charts. Well the boy thought, and decided that he had a chance to get to the heart of his acquaintance....but naturally from the other side.
