The secret of his wife and young neighbor

I am a freeter virgin. After graduating from college, the days were uneventful. However, my life changed when Kuriyama and his wife moved in next door. My wife's name is Rio, and I am very good at bridging the gap with provocative clothes, and I have an affinity with Mr. Rio. And one summer day, when I was invited to Mr. Rio's place to teach me how to use the computer, I fell in love with Mr. Rio, who was drenched in sweat. I pushed him down, but he was a month late.
