It's an interesting fantasy to paint such a fat ass green! Ladies with such an ass are especially good in the crawl position, a boner is assured. Except you have to have a decent length tool. If you don't have one, I recommend laying the lady on her back and fucking her with your hands on her thighs pressed up against her belly. Otherwise you can't get the dick in deep.
That mulatto was asking for his dick. All she does is invite the guy to touch him there, rub him there. Little titties are really into sex. All they wanna do is put something in their mouths and cum. And here's a hard white dick for free.
