Interesting thought as my wife and I watched this. Her butt fat in the second half is helping her pussy slam down on the cock. Now we wonder if it's a biological aspect by Mother Nature to insure a great fuck. Will keep our eyes open on other peoples' videos (and ours). So we took a fuck break to test it out, first slow, without her fat doing that, but when she got into Reverse Cowgirl and kicked it up a notch or two, yes, it absolutely is!!!
