The self-teller of a six-year wife swapping experience is Xu Lei (pseudonym), and my wife is Yunjuan (pseudonym). I am planning a foreign-funded enterprise. My wife designs a state-owned enterprise. In the eyes of colleagues, I am a model husband. I never go out to socialize casually and do not mess with each other. In the eyes of friends, we are a loving couple who are loving and can't escape the baptism of time. The initial vows can ultimately resist the time like water. After four years of marriage, our lives become dull. Facing the burden of life, a fiercely competitive society, our marriage has a crisis. At this moment, a mysterious woman with elegant temperament and fascinating appearance was next to me. She guided step by step, carefully planned, and gradually hooked up my inner desires, and brought me and my wife into the ocean of desires, so that we could not extricate the crisis of marriage. The mysterious woman appeared beside me, and led me little by little into the ocean of desires.
