Maybe they just love anal sex. Then again, it could be that the taste of a cock sliding into their mouths drives them wild. Or, it could be they love getting that pussy tapped by a horny stud. Whatever way they can, they grab their pleasure where they get it.
They love their cock, they love their cunt, they love it up the butt. Others call them fuck-puppets because they love to rut. These are modern women-up for it! They'll take on any man, fuck his brains out, drain his balls, then do it all again.
