[Reducing Mosaic]MEYD-424 A pure love diary of me and my brother-in-law craving each other and having unprotected sex during my husband's overseas business trip. Rin Tō

I got along well with my brother's wife, and we often ate meals together or hung out as a trio, so maybe that's why my brother wasn't on guard. On the day he left for his business trip, I crossed a line I shouldn't have. In the room, it was just her and me. My younger sister-in-law teased me by hugging me. Before we knew it, we were kissing repeatedly… A vivid week-long record of my brother's wife and me indulging in adultery while he was away.
