After joining the drama club, Katayama bonds with the reserved upperclassman Nishida over their shared interest in costume design. When she sends him photos of herself modeling an outfit she created, his feedback leads to an invitation to her home, where a private and provocative photo session unfolds. Meanwhile, student council member Uchino joined the committee solely to be near President Megumi Hokura, whom he deeply admires. His diligent work is constantly disrupted by Hokura’s suggestive movements at her desk, which appear deliberately intimate. Unable to address the situation, Uchino endures quiet torment until a dropped stack of documents forces him to bend down, revealing a compromising view that shatters his restraint. Within the swimming club, Captain Kurotaki enforces a demanding new training regimen under which male members are summoned individually after practice and promptly quit within days. When the narrator is finally called into the equipment room, he is ordered to strip for questioning, leading to an intense sexual encounter orchestrated entirely by the captain. Elsewhere, a student named Mayu attends swim class only to realize she has forgotten her underwear. Thrilled by the risk of exposure beneath her skirt, her daring escalates from secret self-pleasure in restrooms to using remote-controlled toys in empty classrooms. When a male classmate unexpectedly walks in on her, she recognizes an opportunity to push her exhibitionist fantasies even further.
