NTR (Netorare) - The story of a septent, sexually exploitative laborer whose wife is taken by her illicit father. (Ito Saran, NTRD-123)

Even though I'm just an ordinary person, I studied hard in school and worked tirelessly after graduation, and I succeeded, marrying a beautiful wife. Yes, I seized happiness when I was young. However, my father and I don't get along. Ever since I decided not to take over his carpentry work, we haven't had a proper conversation. So, I leave all of my father's work and management to my wife. My wife and I have a good sex life, but after I ejaculate once, I can't ejaculate a second time, even if my wife begs me to, I refuse. One day, I came home early and found my father covered in sweat, and my wife had taken a shower in the evening. Listening to them talk, they didn't seem to be lying, but it gave me a strange unease. Finally, I witnessed my father and wife having an affair. Why... "We're so happy..." What did I do wrong? As I thought this, I found my penis was very erect, as if I was about to ejaculate at any moment...
