My husband has been single for two years, and now I live with my daughter and her husband. One day, she was asked by her son-in-law, Ichiro, who mistook her for her daughter when she got drunk, and she was fascinated by his too splendid big cock. Since then, she was captivated by the big cock, telling her that she was "for her daughter's couple", and blatantly invited Ichiro at every opportunity, regardless of her day or night. Unable to resist the bewitching charm of her mother-in-law who does not choose her means, her frustrated son-in-law continues to be squeezed by her mother-in-law over and over again.
