Apparently my brother is once again on a business trip to a local branch office this month... One weekend, my brother's wife, Miki, who I, as her younger brother, would call "my brother's wife," asked me to run a small errand for her, so I dropped by their house... By the way, my brother's wife, Miki, has a body that makes any man's gaze flow with her huge breasts and huge ass... Then, one day, I witnessed my brother's wife, Miki, cheating on me with another man...
