This lora is trained on clips of women grinding pussies against erections, primarily for a leaning-back cowgirl position, often with their hands pressing the penis against them. The emphasis is on the woman's hip-rocking/hip-thrusting motion.
This model is NOT good at back-and-forth grinding where the woman is straddling the man and moving strictly back-and-forth. (Even though such clips were in the dataset, for some reason it just didn't turn out).
I'm not 100% satisfied with how this one turned out so I might try tweaking the dataset and trying a V2, but please give it a try and let me know your thoughts.
