I'm a virgin who has enrolled in a chaotic and erotic part-time school - Sasaki Aki, Kururugi Aoi, Kanae Ruka, Tamaki Kurumi

I was bullied by a huge cock, so I enrolled in a part-time school that is rumored to be able to have sex! With high expectations, I opened the door to the classroom, and found chaotic classmates! With Aki, a housewife who admires kogyaru, Aoi, a plain-looking girl, and Ruka, a minimalist yankee, and the usually serious Mr. Tamaki, the school life of an overly lewd school begins now!
