Yukie, 54 years old, lives comfortably with her son in a luxury apartment with the income from the company left by her late husband. Her gentle and gentle Yukie doesn't suit her appearance and her libido is extremely strong. She is a big wine lover, and when she gets drunk, her lower body is sloppy, and she makes her son have a blowjob and sex partner, and uses her son as an "outlet" for her sexual desire. One afternoon, her brother, who is in charge of her company, comes to visit her when she is having trouble with cash flow. Sachie, whose hobby is alcohol, puts money aside, and talks about the old days when she met again after a long time. A fifty-year-old mother with a ripe and plump body suddenly changes into a woman.
