My wife is a stunning beauty who turns heads wherever she walks, and at first glance, we seem like the perfect, happy couple. But I've been carrying a deep secret burden—the source of which is my own son's inadequacy. He's completely useless, and I've overheard my wife say, "Love isn't just about sex." One day, I accidentally caught my wife masturbating for the first time since we got married. In that instant, an unexpected surge of excitement and guilt overwhelmed me. Before I knew it, even my detestable son was rock-hard. Standing there, a single thought flashed through my mind: "What if my wife were alone with another man..." That fantasy lingered, refusing to fade away.
