ADN-757 | My sister-in-law (my brother's wife) has returned again this year, and we're spending the week indulging in our once-a-year physical relationship. Shiramine Miu

My brother's wife, Miu, comes home once a year with my brother.
While he's here, he spends the whole day fishing from morning till night, ignoring Miu.
Left behind, the distance between Miu and me naturally grew closer, and ever since we crossed the line a few years ago,
we've been indulging in a physical relationship for this one week every year.
