I don't think I've ever seen (and certainly never experienced) a girl push-back - to "fuck" the guy - all the way from a prone position. Her orgasm(s) must have been pretty powerful to give her all of that strength!
"All women" should be like this woman. They love it in the ass and push their butt back against the guy just like she does. And her having an 'anal orgasm' is icing on the cake. I love it when a woman cums from being fucked in her ass.
