Reiko lives a normal married life. The only dissatisfaction is that my husband's sexual desire has been decreasing recently and the night life is not going well. One day, a man who became her husband's new subordinate came to the house. The man who had been Reiko's ropes trainer and made her sadism blossom. Reiko could not hide her surprise and confusion at the accidental reunion. “Long time no see… ma'am.” My body, which had forgotten the past and got used to a mediocre married life with my husband, began to tingle.
