My brother's wife and I had a good relationship, and we often went out to eat and hang out together, so maybe my brother wasn't on his guard. On the day my brother left on a business trip, I crossed a line that should never be crossed. My wife and I were the only two in the room. My wife hugged me as if to tease me, a younger man. We both accepted and continued kissing... This is the vivid record of a week in which my brother's wife and brother-in-law repeatedly committed adulterous acts while my brother was away.
