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!
If the sister does not go to Mohammed, Mohammed goes to his sister. His half-brother had his eye on his sister for a long time, and she was playing the innocent chick. Only when he took his dick out of his pants did her eyes open to the fact that he could make a good lover. Yeah, and her pussy was leaking before she came to her senses. And what happened was, she took it in her mouth. So females only resist for the first few minutes, until the front starts dictating their will to the head.
I want to do it that way
