Tricky action but I think I finally got something good enough to post.

Works best with simple prompts at 720x1024 of 1024x1024.

Definitely still produces a lot of grabled nonsense but it gives something usable about 40% of the time.

Trained on base SDXL but I am getting good results on Juggernaut and I think other models should work well too.

Keep your prompts real simple
I used the base prompt :
woman fingering pussy. <lora:2FingersSDXL_v03:1> , spread legs fingering
for most of my example images.

Happy fingering! Let me know if you figure out any tricks to get good results.
