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.
This is what the negroes did for the glory and fucked this sexy blonde hard with the whole crowd. Like how the negro roughly took her by the head and just shoved his huge device in her mouth! And then in her pussy and then in her mouth again... A lot of girls dream of that kind of roughness.
The guy is lucky with his sister - she is a nipple. She's ready to open her mouth for him to stick it in her. Apparently she serves him regularly, because he no longer feels affection for her, but fucks her like a street whore - rough and bold. However, she seems to like this treatment.
It's a good way to diversify sex for a couple. And for a single girl, it's not bad fun either.
