This mistress is not adventurous and there was something her boyfriend had been asking her to do to him for a long time. She had refused to do it but now that his birthday was here, she figured that it would be the treat of a lifetime for her to do what he wanted. So she checked out facesitting videos on the internet and she trained herself to dominate using her ass and facesitting then she did it beautifully for him. Best birthday present ever.
