I would start with something like
>A photorealistic picture of an extremely fat bottom-heavy 30-year-old African American SSBBW woman with dark skin and a beautiful face. She has extremely tiny breasts, a very narrow waist, absolutely no belly whatsoever, extremely wide hips, and a gargantuan round fat protruding buttocks. She is swimming in a swimming pool on a sunny day.
It's never exact though. Then I pick the good ones from all the images that show up and add the actions to make the videos like
>She swims out into the deep water. The camera goes underwater. She is in the water up to her neck. Her extremely wide fat hips and extremely round fat thighs and chest are bouncing and wobbling visibly and excessively while she is treading water.
I keep tweaking the prompts to get something I like, but that's basically it.
