I'm not super good at it either, Most of the images you see are with the following prompt
"photo of woman lying down, brunette, face down on floor, chubby, facing away, big butt, business pants, tight pants, pantsuit, suit pants texture, pockets"
and the traceover from the screenshot of fallout of the reaper in my previous post as the init image
. I set the strength from 50-60%. Some of my sketches don't work as well, sometimes the AI starts drawing faces where they shouldn't be. Images where parts of the woman's anatomy are hidden seem to cause the most problems, so do images with perspective. That being said the fallout of the reaper image worked really well for some reason even though it's at an angle.
I got a really good OTS prompt going with a traceover of a still from a Velvets Fantasy video using the prompt: photo of woman being carried by female ninja, tight pants, business attire, suitpants, suit texture, big butt, chubby bbw, slumped over, bent over
The "female ninja" part is not perfect ol girl looks like she's about to throw out her back, but it's totally usable with a bit of image editing and more importantly, it's sexy as fuck.
