Higashi Shouta accidentally discovers the scandalous secret of the "Ladies Club" at the prestigious Shiratori Academy: its members are high-class virgins who use boys for sexual experimentation. To ensure his silence, the girls coerce Shouta into becoming the club's newest male member, subjecting him to a series of intense encounters as they compete to break his resolve and satisfy their own desires.
Shouta finds himself overwhelmed as the girls of the academy continue to push their boundaries. After being coerced into helping both Tama and Rune lose their virginity, Shouta is later visited by the composed Nao, who leads him into another passionate encounter. As he reflects on the unique charms of each girl, Shouta begins to fantasize about a harem ending, only to be brought back to reality by the headstrong Reika.
