My name is Kozue Onoe. My wife Wakaba and I have been happily married for three years. Since moving to our neighborhood half a year ago, my sister and her husband often come to visit our home. My free-spirited sister recently had sex with my brother-in-law at our house, and that's when I found out he has quite a large penis. Anyway, I thought our marital and family relationships were harmonious, but the other day I saw my wife and my sister's husband embracing each other.
