When I returned from a business trip, my wife Miho and my father were surprisingly close. Before the business trip, it was still dangerous, but they had become close since when. The next day, when Miho and her father went out together, I was cleaning the house and found a lot of pornographic pictures in my father's room. There was a picture of Miho being fucked by her father. I could only continue to watch my beloved wife enjoy being toyed with by her own father, even though I felt like my heart was being torn apart by this unexpected event.
