ATID-574 | "Old man, I'm home." Emma, who took her virginity, has returned for the first time in 10 years. Futaba Emma

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