I get the impression that the husband was filming this love session and his wife was being shared with his son to keep her happy in the bedroom. I think that a family sexual relationship like this is a fantastic way to keep a wife satisfied in a discreet manner and no one outside the home will know that she is fucking two men and enjoying the pleasure of receiving their love juice in her belly.
