[NITR-021] My first naked adult experience was with my father's acquaintance's busty wife... Sayuri Mikami (Censored)

This is a story from when I was still in elementary school. My father's friend built a new house, and my father and I visited to celebrate. What happened at that time was so shocking that I can't even put it into words. In the evening, my father and his friend have a drink. My wife, Sayuri, gave me and the family's child a bath. I got excited when I saw the naked body of an adult woman for the first time. Later that night, I spied on the couple's activities. My fantasy never stopped, and the next day, when I was alone with Sayuri, it became reality! !
