At St. Nympho's Academy, a male teacher is assigned as an advisor of the Bitch Club under the half-hearted order of the dean, who says, “If you refuse, I'll show you hell."

He has an average appearance for his age, and although he may seem a little unsociable to the uninitiated, once you get to know him, everyone judges him to be a nice guy. Some female students think he is pretty cute and might be their type. He is also very popular with teachers, perhaps because of his age.

His personality is kind and sincere. He has a side where he cannot refuse requests. Her friendships with men and women are quite normal. However, even if someone likes him, the opposite sex will think that he must have a girlfriend, and he will remain a friend. In other words, he is a virgin with no dating experience.

He admits that he has a high sex drive, but doesn't uses sex services and health deliveries because it costs money. On his days off, he masturbates in solitude, using magazines, pornography, and erotic images and videos uploaded on social networking sites. His dick size is average but he has endurance.

When he meets a group of peculiar bitches, he is led around by them, and his daily routine changes forever. What will happen to him?
