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.
The main thing for girls is to feel that they are valued, to hear the words that are pleasant to their heart and not to rush. She will still say Yes, only it will be her choice. So the stranger acted completely professionally - for that he got the award. And she's a great nipple.
She's a "no-no."
