ADN-757 · A Week of Indulging in a Physical Relationship Once a Year With My Brother's Wife, Miu Shiramine

Miu-san, my brother's wife, comes home once a year with my brother. While he's here, my brother completely ignores Miu-san and spends all day fishing from morning till night. The distance between Miu-san, who is left behind, and me naturally closes, and since we crossed the line a few years ago, we have been indulging in a physical relationship every year during this week.
