During a literary club training camp, participants were assigned separate rooms for men and women. As there was only one female member in the group, the male members took turns attempting to seduce Shiori, who served as the club's director. The interactions between these individuals became increasingly intimate and secretive. One of those involved was Makoto, who had no idea that Shiori had already become a "meat urinal" within the Literature Club. Despite this lack of knowledge, Makoto confessed his feelings to Shiori and began dating her. However, their relationship seemed somewhat awkward due to the circumstances surrounding it. The many beatings the male club members inflicted upon one another eventually transformed into an ecstatic experience that left them unable to forget its pleasurable sensations. As a result, they found themselves drawn back to the club room where they could continue these intimate encounters with their fellow members. In doing so, they finally crossed the line and fell into the world of pleasure.
