My wife is pregnant with our second child. My only joy was the conversations I had with Futaba-sensei at my eldest son's nursery school. "Good luck at work!" Her refreshing, motherly smile cheered me up every morning, but one day... my wife and eldest son went back home to give birth. A week later, with my room messy and my sexual desire building up, I saw Futaba-sensei at home. My everyday life became extraordinary. From that day on, I had sex with Futaba-sensei at home over and over again. Over and over again.
