There are two main plots in the world of hentai. The first one tells about the life of a popular singer who suffers from an irrepressible sexual desire. She can satisfy her passion only with the help of the head of the company she works for.

The hentai tells the story of a humble and silent teacher who, after many years of work, becomes the director of an educational institution. Having gained power, he loses control of himself and his dark desires. The academy is turning into a place where violence and debauchery reign, and teachers are becoming like sex maniacs.
