Forbidden sex with my wife's mother, Part 4: I'd rather have a mother-in-law than my wife... Chigusa Mizuki
Chigusa's daughter got married six months ago and is now living with her and her husband. One day, Chigusa witnessed her daughter and her husband having sex. It has been a long time since Chigusa lost her husband, and she gets excited and masturbates. From that day on, Chigusa went to watch her daughter and her husband have sex, and she started masturbating in the kitchen and bathroom. One day, while her son-in-law was in the kitchen, Chigusa came. The towel wrapped around her chigusa falls off and she becomes completely naked. Her son-in-law covers her with excitement. "I can hear you masturbating in the bathroom."
