This autumn, my wife and I visited my parents' home in the countryside. My family runs a farm, and after my parents retired, my younger brother Minoru—rather than me, the eldest son—took over the fields. He possesses a thick, dark, and powerfully built cock, completely different from mine. Wearing a yukata to the village's autumn festival, my wife became instantly infatuated with him. Unexpectedly, our family reunion became the catalyst that deepened the bond between my wife and my younger brother.
