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 got drunk and mistook him for his daughter. Since then, she has been captivated by big cocks, saying, "For my daughter's couple," and blatantly inviting Ichiro at every opportunity, day and night. Unable to resist the bewitching charm of the mother-in-law who chooses no means, the frustrated son-in-law continues to be squeezed by the mother-in-law many times.
