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!
And what a job interview, reminiscent of a job interview for the boss's secretary! I have to hand it to you - the lady did very well, she would have definitely taken the job as a secretary. Although, frankly, her tits are not very good!
