He is an otaku, a shy, boorish boy, and has no girlfriend. The protagonist, Junta Morinaga's life at school is terribly lonely. He spends his days in seclusion, trying not to be noticed, appealing to the fact that he is harmless to others so that he will not be bullied.

His sexual desire is stronger than anyone else's, and his head is always filled with erotic thoughts. He masturbates at night thinking of some of his female classmates, especially two of the most popular girls in the school.

Yankee bitch “Yuna,” who is a slutty, out-of-uniform girl and Miho, a nerd-friendly, sex-loving gal. Junta thought he had nothing to do with these gals, but one day after school, Miho and Yuna called him to the gym and told him, “Otaku-kun, why don't you buy us as your girlfriends?".

The gals who were once the cream of the crop turn out to be dirty, slutty, and voyeuristic girls! This is a coming-of-age story that begins with prostitution with the beautiful girl pussy-selling JKs!
