Noriko, who started attending wine school to enjoy her later years, became close with a younger man named Hiroshi whom she met there, and the two began regularly enjoying drinks together alone. At Noriko's home—where her husband was never around—they made a habit of savoring fine vintage wines, followed by deeply savoring each other's bodies. As these days continued, Noriko and Hiroshi found themselves unable to stay apart. Then one day, Hiroshi invited her on a trip to a special winery, leading them both toward a new, thrilling experience.
