At my school, anyone not in a sports club has no rights, and the girls' group in the literature club is treated as gloomy outcasts... But in reality, they are a squad of super repressed, horny girls who devour erotic doujinshi and dedicate themselves to masturbating until they collectively cum 100 times a day!? Finally unsatisfied with just masturbation, these girls locked onto me, a guy from the gloomy group! I've been appointed as the literature club's "cock manager" to help the female members with their 100-orgasm acme challenge! Once school lets out, their repressed nature vanishes, and their explosive sexual appetite leaves my balls completely drained every single day! But looking closely, the sight of these super cute girls swarming my dick is breathtaking! As the only male member of the literature club, I intend to continue dedicating myself to harem sex with all of them!!
