Kyonyuu Dosukebe Gakuen - Season 1

A prestigious all-girls academy abruptly transitions to a coeducational model. The student body, drawn from elite families, is largely naive regarding matters of sexuality, adhering to principles of abstinence and disdain for male company. This prevailing attitude is contradicted by the clandestine Otome Club, comprised of four students. The club's members compel male recruits to adopt feminine attire, using them to act out previously repressed erotic fantasies. Their activities are inadvertently overheard by a male student, leading to his discovery by the group.
