NTRD-123 Netorareze: The story of a silent manual laborer whose father had a virile sexual appetite

Even if I was such a dull guy, if I studied hard in my school days and worked hard in society, I could get promoted and marry a beautiful wife. Yes, I had found happiness at a young age. However, I didn't get along with my father, and I haven't spoken to him since I decided not to take over the carpentry business, which was my father's life. So I left the accounting of my father's business to my wife. My wife and I didn't get along well at night. However, I'm the type of person who can't have a second round after ejaculating once, and even if my wife asked me to, I always refused after ejaculating. One day, when I came home early, I found my father covered in sweat and my wife taking a shower even though it was evening. From what they said, it didn't sound like they were lying. But I felt a strange sense of discomfort. And then, I finally witnessed my father and wife having an affair. Why... I was so happy... Where did I go wrong?
