Five years ago from now on, the bookmarks I was a student got a relationship with Masashi 's cousin from a little momentum. However, I did not have sex, I just taught Masashi who does not even know masturbation. Both of them were in doubt at that time. Since then, it felt awkward, the bookmark kept far from him. Then the moon came running, and the two were to meet again ... .... Same as a cousin 's monkey loneliness, crazy the bookmark body!
