A camp event organized by the neighborhood association, rumored to be attended by many suspicious middle-aged men—despite her reluctance, Aika is forcefully dragged into participating. As the sole female attendee, she's coerced into drinking, gets intoxicated against her will, and is eventually dragged into a tent and brutally assaulted. Aika, harboring hidden sexual frustration, shamefully reaches climax. Using recorded audio as blackmail, the men threaten her into submission, and from then on, she's repeatedly gang-raped by the neighborhood men at every subsequent camp. Over time, Aika begins to eagerly anticipate the very event she once despised. Before she realizes it, she has completely transformed into a submissive woman, addicted to their abuse.
