Rei Furuse is a married woman, but her husband is a guy with erectile dysfunction who only knows how to bury himself in work. Today, after seeing her husband off to work, Furuse received a phone call from her ex-boyfriend saying that he wanted to meet up to reminisce about old times. Memories of the past suddenly flooded the mind of the lewd woman, so she decided to go to his house to see him. And then the two of them made love blissfully to each other as they did in the days when Furuse was not yet married.
