Well, let's say not only with anal sex, the lady was worked all over so hard! And she hardly gives anal sex, it is obvious that from vaginal sex she enjoys much more! And she thoughtfully did not take off her glasses - it is assumed that her partner will come in the face, and there is a need to cover her eyes from the sperm!
Lucky for those adult sons whose mothers look so young and sexy and can so skillfully teach love lessons, although if the mother was dressed in a regular robe and slippers, not shoes, the movie would have looked more believable.
