The reason for the incident is that she complained that her sex life with her husband was not very harmonious, because... the two of them started dating and got married for too long, and they were tired of it and had no passion. When they first started dating, they spent almost every weekend in a hotel. Now, it only takes only once a month, but they still have to do it. The main reason is that they are too familiar with each other, and they have become brothers with each other. Looking at each other's sexual organs is like looking at yourself. There is no feeling anymore. It is better to touch yourself than touch the other person.
