Sachiko, a mother-in-law who quarreled with her husband and rolled into her daughter's couple's house. I fall asleep while drinking alcohol and having my daughter and her husband listen to their complaints. A son-in-law who carries Sachiko to the bedroom while being worried about the body of her plump mother-in-law. Sachiko seduces her son-in-law with half a playful saying, "Take off your clothes." The son-in-law got an erection when he saw Nobra's chest, but Sachiko became happy when she noticed it, and after that she began to tempt her often while making fun of her. One day, when my daughter-in-law went out at a girls-only gathering and became alone, my son-in-law and mother-in-law finally overlapped.
