北川玲子 - 旦那には言えません。私はこの秘密を墓場まで持っていきます。パート1

Her step-mother, who lives apart from her husband on a single assignment, is completely estranged from him and seems to be having a hard time with her sexual desire these days. However, she has no intention of cheating on her husband, so she seems to be indulging in masturbation by herself. The only one who could pleasure her step-mother's body was her step-son, who is forty years old and still in the throes of womanhood and fucking! A degrading sexual intercourse filled with immorality! They fall into a physical relationship!
