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 Asian girl gently and long caressed the cock with her tongue, not forgetting the balls as well. Worked every millimeter, while moaning so languidly that her partner wanted to fuck her. His cock just fit between her beautiful breasts, and her pink nipples swelled up. She lay down and wanted him to cum inside her. Ending on her tummy gave her a special pleasure. She caressed her cock with her hand. I wish I had an Asian girl like that, because they're all so temperamental.
Where do you live, Lera?
