Since my business trip destination happened to be near my brother's rural home, I asked them for lodging and they kindly agreed to let me stay for a week. My sister-in-law, Iroha, had fully adapted to country life and was comfortable going braless in front of others, leaving me flustered. Before I knew it, I found myself constantly thinking about her... With nothing else to do in the countryside besides work, I gradually found it impossible to suppress my feelings.
