See how that pussy clings to that fat cock on the upstroke? You get that when two things happen. A tight fit or not enough lube, or the pussy has been beat up so much it softens up and looses muscular control. (yeah, that's three, not two things). Asspussy is a better for a dick than vagina. Vagina is good. But ass, on a man or woman, is naturally tighter. And there is nothing better for the ass than a hard dick. They go together like milk and cereal.
