I am a ronin living like a freeloader in my brother's apartment, gnawing on the heels of my hardworking and serious older brother, while thinking that I must succeed in the entrance exam this year, but I was harboring irreverent feelings towards my brother's beautiful and kind wife. One day, my brother went on a two-night, three-day business trip to the countryside. Seventy-two hours alone with my sister-in-law. I exploded the feelings I had been holding back until then, and during the three days my brother was away, I had sex with my sister-in-law day and night.
