I simply could not find a way to put this pose into prompt wording in a way that MiniMax H3, Qwen, or any other image model I tried would accept. Most of the models wanted to pose the girl underneath the woman with her body oriented exactly the opposite way as this (eyes looking up from the pussy, legs pointing assward).

If not that, I got the woman on top balancing on her toes instead of down on her knees. If not that, bizarre contortionist crap with extra bodies and heads and legs.

https://justsketch.me/ to the rescue.

Of course, if I could have found real humans posed exactly like this, without hours of searching, I might have been able to use a real image as a guide. Since MiniMax H3 was willing to work with this justsketch.me image as a reference image. however, I was able to get my video characters correctly posed this way instead.
