From the front as well as from behind - well, absolutely flat woman. Only one advantage is obvious - well-designed orifices. And of course due to the flat buttocks it's very convenient to pull your partner in the anus, even without bending her over. And I don't see anything else interesting in this lady! The man is basically of age, so probably the determining parameter for him is the age of the woman and the possibility to work her anally!
The brunette came for a massage not only for the purpose of stretching muscles. Such chicks also have fantasies about massage therapists. The piercings on the intimate parts of the body even to me speaks volumes. That she is not indifferent to sexual pleasures is clear at once. And how her body reacts to the touch of a hand - an experienced masseur will understand at once. So to stick it in her mouth is a matter of time and the degree of arousal, which this male skillfully manipulated. Another chick got on his sex list.
Oh Lekha is as good as ever! He's got the last girl on the block!)
