Miyuki and Momo are schoolgirls. The two best friends have had almost no experience with the opposite sex and live their days as pure and chaste, but Miyuki dabbles in social media and meets a man named Suzuki. One day, Suzuki calls Miyuki out, saying, "The president of an entertainment agency he knows wants to hire you as a talent," but he is gang-raped and filmed by a group of men who call themselves Kudo, and the men confess to being gangsters, taking control of him. They then learn of Momo's existence and extend their clutches... leading her into a gruesome sex feast known as the "Masochist Club"!
