We've been married for four years, and although we don't have any children yet, we are living a happy married life in our own way. One day, Saki was having a reunion at her alma mater, so I sent her off with a nice feeling, but she didn't come home that day and came back the next day before noon, but I found a video on an unknown video camera in her bag. We watch the whole story of how my beloved wife becomes lewd, and her behavior is clearly different from usual.
