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.
We observe the opposite picture. It's not the fast-food worker feeding the customer, but the customer feeding the girl fast-food worker. The question is: Who has the healthier and more natural food? You can see it in her face - she's asking for more!
