My sister-in-law is back again this year. It's that time of year again for indulging in physical intimacy ~ Shiramine Miu ADN-757

Every year, my sister-in-law, Meiyu, would go back to her hometown with my brother. As soon as my brother got back, he would spend all his time at the fishing pond, completely ignoring my sister-in-law, Meiyu. Naturally, the distance between my neglected sister-in-law and me grew closer and closer. Ever since we crossed that line a few years ago, we would indulge in physical pleasure during this week every year.
