While My Wife Was Back At Her Parents' House After Getting Pregnant With Our Second Child, I Had Nonstop Sex At Home With The Teacher From My Eldest Son's Daycare. Ruisa Tsukizuki

My wife is pregnant with our second child. My only pleasure was the conversations I had with Rui-sensei at my eldest son's daycare. 'Do your best at work!' Her motherly, refreshing smile gave me energy every morning. Then one day... my wife and eldest son went back to their hometown for the birth. A week later, my room was a mess and my sexual desires had built up. What I saw in my home was Rui-sensei. The ordinary became extraordinary. From that day on, I had sex with Rui-sensei at home, over and over again.
