Two married women who met in college, later worked at the same company, got married, and remain close friends. Although they now live in different cities, they stay in frequent contact and often travel together. One day over lunch, Sakura Misaki mentions a video she's recently become obsessed with—AVs—and confesses she'd like to appear in one herself. Umi Oikawa is surprised but not entirely shocked, knowing Sakura had been sexually active since their college days. Initially, only Sakura was planning to participate, but Umi eventually joined too—because she had been struggling with a sexless marriage. Though she enjoyed sex, her husband was emotionally and physically distant, leaving her sexually unfulfilled. Tempted by Sakura's bold proposition, their mutual desires aligned, leading them to co-star together. This AV became their shared outlet to satisfy each other's long-suppressed needs.
