At my school, where no one has any rights except for the sports club, the girls in the literature club are treated like loner characters... But in reality, they're a group of extremely shy and perverted girls who read erotic doujinshi and masturbate every day until they've all reached a combined 100 orgasms! Finally, no longer satisfied with masturbation alone, the girls have locked onto me, a member of the loner boys' group! As the literature club's penis attendant, I'm tasked with helping the girls with their 100 orgasm challenge! After school, the shy girls reveal their true nature, their explosive sexual desires leaving my balls completely empty every day! But when you take a closer look, the sight of all those super cute girls flocking to my dick is truly breathtaking! As the only male member of the literature club, I intend to continue enjoying harem sex with you all!
