While my wife was on her way home, my wife's older sister, Konatsu, came to see how she was doing. She was happily chatting with a guest she hadn't seen in a long time, but... when Koji took a bath, the situation changed completely. "Oh, sister-in-law, please don't come in!" In front of her, the defenseless and beautiful body of Konatsu, even though she thinks she's no good, her lust wells up.
