I've been married to my wife Yuu for a year, and since my mother passed away, I've been living with my father. Although I was happy, there was one problem: erectile dysfunction. We wanted children and tried various methods, but nothing worked, and I was troubled. One day, I caught my father massaging my wife, which caused a reaction in my groin. This had never happened before… So, I proposed to my father and wife, 'Can you show me the two of you having sex?'
