My brother went on a solo business trip to a local branch office this month, as usual. One weekend, I was asked by Miki, my brother's wife (or rather, my sister-in-law), to run an errand and visited their house. By the way, Miki has a body that any guy would steal a glance at, with her stunning breasts and explosive ass. One day, I accidentally witnessed Miki cheating on my brother with another guy.
