ATID-574 Old man, I'm home. Emma, ​​who took my virginity, is back for the first time in 10 years. Futaba Emma

``Ojisan, how do you have sex?'' It was a casual comment. It may have been a joke, but I was driven by a sense of duty and forced myself on Emma, ​​who didn't like it. From then on, we had sex whenever we had time until she discovered the joy of sex. But one day, she suddenly disappeared. ...10 years have passed since then. Emma is back.
