This is an all-in-one heterosexual cunnilingus LORA (i.e. "Ultimate") that envelops virtually every position possible (standing, sitting, lying, close-ups, facing away, facesitting) with the only exception being POV. Trained on the largest database for cunnilingus (over 3,000+ high quality images), I want this to be every cunnilingus lover's ultimate creation tool.
V1 is experimental, as success rate is roughly 70% at weight 1. So a little bit of patience is required to get good results. FLUX.1-Dev being a distilled model with catastrophic forgetting does not do as well as SDXL or SD1.5 in terms of foreign concepts, and anatomy is a bit wonky.
When you do get good results however, image quality and compositions are great, with rarely a need to upscale or fix faces (female faces are actually more beautiful than base Flux).
This LORA shines most at img2img including upscaling. I recommend upscaling any cunnilingus image with it!
Can produce fully nude female humans with proper looking nipples and vulva, so it can be used for NSFW content other than cunnilingus.
This is universal in style, so it will work with photorealism, anime and 2.5D.
Example Prompt:
For photorealism:
<lora:Cunnilingus-Universal-Flux1Dev-V1:1> a very detailed photorealistic photo of a man is licking a woman's vagina in bed, cunnilingus, oral sex, nude, brown hair with bangs, medium breasts, light and shadow
For anime:
<lora:Cunnilingus-Universal-Flux1-V1Dev:1> a anime image of a man is licking a woman's vagina in bed, cunnilingus, oral sex, nude, brown hair with bangs, medium breasts, light and shadow
Man and woman can be interchanged with boy and girl. This can be useful for anime.
Tweak the prompts as necessary, but attempt to keep it under 150 tokens (75 tokens and under is best).
LORA weight can be increased further to 1.1-1.5. This can help improve consistency, but can degrade image quality. Only do this if the LORA continuously fails to generate a proper cunnilingus image.
Portrait resolution is the best (896 x 1152 and 640 x 1024 are both tested well).
Distilled CFG scale 3.5-5 and CFG Scale 1.
Euler Simple.
20+ sampling steps.
