UPDATE: Illustrious version is now up. Trigger word is different with mostly the same image set used to train this like the Pony versions. Human/humanoid characters will have the best effect on this blowjob lora, but furry/anthro characters can work too. Hassaku checkpoint works best from my testing.

This is a vacuum fellatio template trained by the artist Inu-G. This artist has drawn a character doing the vacuum fellatio many times, but I focused more on the more ridiculous side to where the character's mouth is more stretched out. Furry and anthro characters work perfectly too.

Positive Prompts: VFIG, 1boy, 1girl, female focus, faceless male, penis, blowjob, fellatio, vacuum fellatio, sucking dick, anteater face

Extras: side view, testicles, close-up, eye roll, looking up, double blowjob, disembodied penis, fellatio through underwear, tongue out

The double blowjob tag might generate 2 mouths for the character which is not intended. Just a heads up on that lol.
