Katekyo! (a.k.a. Private Teacher!) is a yaoi manga by Moegi Yuu. It describes three stories, the main one being about Rintarou and his tutor Kaede. Rintarou feels akward around his tutor, since he is attracted to him. When he gets a bad grade, his tutor punishes him and Rintarou realizes he’s in love with Kaede.
This doujinshi work talks about the two of them, but..in the animal edition! What will happen when the bunny is captured by the wolf? ^^
