This LoRA adds belowjob footjobs to PonyXL.
Works best at 1 or 1.1 or you start missing toes. Still comes out cursed sometimes, as it's combining two things Stable Diffusion is bad at.
Use the tag "selfsuck" if you want 1girl alone. For feet appearing out of nowhere from another woman, leave selfsuck off. If you want two women's faces, use "FFM threesome". I saved the "2girls, 1boy, hetero" stuff for photos with all three faces, but none of them turned out.
