[Reducing Mosaic]NGOD-248 Big-breasted sister-in-law rape. While his brother was on a solo business trip, the younger brother witnessed his sister-in-law cheating but couldn't say anything... Yamae Mikio.

My brother is on a business trip again this month, assigned to a branch office in the countryside. One weekend, my brother's wife—whom I refer to as 'Aneki' (brother's wife)—asked me to run an errand for her, so I went to their house. By the way, Aneki, Miki, has a figure that would make any man steal glances—a breathtakingly voluptuous body with massive breasts and buttocks… One day, I caught Miki cheating with another man.
