This is my Fellatio LoRA, with an emphasis on spit and fluid depiction. Great with semen as well. It's prone to blowjobs viewed from the side, rather than a POV of the crotch. If you want a crotch POV, then put 'pov, crotch pov' in your tags.

The weight is good from 0.6 to 0.8, but I use 0.75 weight. Sometimes the images produce extra fingers / fingers without arms on penises. For this, inpainting will work to remove them.

If your model has a problem with penises, hands, and fellatio adjacent subjects, then it will have problems with this. The trigger words are "saliva, sloppy fellatio, fellatio".

All pics were made with my custom blends with Hires Fix and orangemix VAE. The LoRA was trained off of NovelAI, so naturally it'll work with most anime-based models.
