Des：Mr. and Mrs. Okajima are in their 50s. Her sexual intercourse has not slowed down yet, and she does it early in the morning if she feels like it, but as she grows older, Keiko becomes more and more unsatisfied with her husband Muneos unruly behavior. In comparison, Muneos son from his ex-wife, Kota, is 30 years old and in the prime of his manhood. In fact, Keiko has been having a close physical relationship with this son-in-law, and is amazed at how hard he is, which is different from her husbands. Its not like shes completely devoted to her husband. He just wants to be penetrated deep inside the woman he is.
