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 blonde may not be young, but she's still in shape. The nigger had a good relaxation, but was it a decoy to distract him from guarding the object? Maybe a robbery was going on at the time, and instead of guarding it, he was fucking the blonde.
