Thirty-eight-year-old mature beauty Rin Okae is interviewed about her ideal sex and asks for an affair scenario. Her fantasy is to play an office worker secretly following her boss to a hot-spring inn, where they cling together through sweaty, sticky adultery. She uses her huge breasts, big ass, and pillowy body through rich sex in both the room and the bath. After returning satisfied, she finds a young adult production assistant she noticed during the interview. The director has arranged a second illicit encounter, giving Rin two rounds of soft, voluptuous sex.
