Just when her daughter had married and the Hanajima family thought it was safe, Mizue lost her husband and became a widow. She strongly advised her daughter and son-in-law to protect the house her husband had built. On a day off, her daughter went out shopping while her son-in-law lazily played games. Mizue couldn't stop nagging her sloppy son-in-law, and gradually her temper heated up. The son-in-law listened silently, but then he attacked Mizue in anger and frustration. Mizue resisted in surprise, but the son-in-law attacked her roughly and violently. Despite her feelings, Mizue's body overreacted and she easily accepted her son-in-law's penis. Mizue let out a sigh as he thrusted violently, and she reached her climax in time with her son-in-law's ejaculation. What was Mizue thinking as she watched her son-in-law's back as he hurriedly left...?
