Reiko lives a normal married life. Her only complaint is that her recent husband has a low sex drive and is not having a good night life. One day, a man came to her house who said she had become her husband's new subordinate. The man was once a man who gave Reiko rope training and made her masochistic bloom. Reiko can't hide her surprise and confusion at her chance reunion. She said, "It's been a long time... ma'am." Her body, which had forgotten about her past and was accustomed to an ordinary married life with her husband, began to ache.
