(My wife is pregnant with our second child. My only joy was conversations with teacher Futaba at my eldest son’s kindergarten. “Work hard!” Her motherly refreshing smile energized me every morning. Then one day…my wife and son returned home for childbirth. After a week, with my room messy and sexual desire pent up, I saw teacher Futaba at home. Daily life became extraordinary. From that day, I had endless sex with teacher Futaba at home. Again and again.)
