Summary

Monster girls have an almost impossible time becoming pregnant. Only about .2% of the time having sex can one get pregnant. For this end a special school has been created. Here humans and monster girls can attend school together where daily sex is required and open sex is encouraged. Taichi has transferred to this school. As a new student he's lost and confused and ends up standing in line to have sex with a catgirl. He's too embarrassed to act when its his turn to have sex but thankfully he's rescued by Hakua Inabashiro, the class president. On the way to get him sorted out with the office he's so taken by her beauty and huge tits that he immediately confesses his love for her and asks her to marry him! Instead of being embarrassed Hakua begins to cry. 'Would you really be interested in me?' she asks and immediately she accepts his proposal. Now, not only is this beautiful bunny his girlfriend but because of his proposal she's exclusively his. Their happy lovey dovey sex filled school life begins.
