Sayaka Koda, a married woman with a big bust, feels emotionally empty in her sex life due to her passive, low-libido husband who quickly penetrates and finishes without foreplay. In her loneliness, she recently discovered masturbation, an act she had never engaged in before, sparked solely by watching hardcore AVs. As she becomes aroused by intense sex scenes, she seizes the opportunity while her husband is away on a week-long business trip and boldly decides to experience an AV herself. Upon arriving at the hotel, she's visibly tense, her body stiff with nervousness. Yet, as a gentle male performer begins caressing her, she can't help but become wet, her arousal steadily building.
