The main character of the hentai is an ordinary guy named Toru, who loves to keep his "erotic fantasy diary", in which he carefully collects the most depraved and lustful fantasies with his classmates. As it usually happens in cliched hentai - the hero forgets his diary in class, and then remembering this, immediately returns there to pick it up, but by an incredible coincidence, he catches red-handed Otori Chikage - a local celebrity and idol of the academy, who wildly masturbates to his "treasure" ... It turned out that she is a real hentai mangaka, who became famous all over the world for her truly horrifying stories in terms of lust. However, she is now experiencing a creative crisis and stagnation in the production of new works. Because of what the deadlines for the delivery of manga sharply moved to the deadline. Otri begs Torah to help her with the writing of manga, and in replacement she will allow him to do with her everything that he described in his "erotic diary of fantasies". Our hero simply could not refuse such a sentence, because he was just staring at the stunning beauty with incredible forms, ready to fulfill all his most depraved fantasies...
