Shortly after her marriage, Aimi's move-in coincided with her husband's busy schedule, leaving no time for intimacy and pushing her sexual frustration to the limit. She begins relieving her pent-up desires through daily masturbation. However, overuse causes her favorite vibrator to break, forcing her to throw it away. The broken toy catches the eye of neighborhood association chairman Gondo, who becomes instantly captivated by Aimi's charm. Driven by the thought, "I'll solve this housewife's problems," he forcefully lures her out and begins a secret affair. Soon, he involves other men in the neighborhood, drawing Aimi into a web of intimate relationships filled with humiliation and pleasure among her neighbors.
