This hentai revolves around literature club on the verge of being disbanded if the club president, Shiori, fails to recruit three new members. Fortunately, she succeeds in getting the required members on board, but at a severe cost. The new members of the club are crude in their behavior, use lewd language, and exhibit obscene conduct towards Shiori. Consequently, the girl becomes a mere sex object, used solely for their sexual pleasure, like a “sperm toilet.” A few days later, a new member named Makoto joins the club, entirely unaware of the unsavory happenings within.
