Ohh boy, do I have some horrific ideas... Let me know if you want a challenge >:)

ignore my previous comment, its literally just saying exactly what your asking here.
Ideas:
This but vertical
This but hands / feet / shoulders / neck / face / mouth / back / vagina / ass
or anything from the parasite anime.

Previous items I have tried to create in my early days of stable diffusion would be a empty organ-less zombie with a split open frontal torso with teeth and flesh. Imagine form the ribs down all the way ripped open like it wants to give you a hug. Obviously idk wtf im doing and failed lmao.

@sevora yeee, they are all just suggestions, so feel free to try if you wish but nothing is required. great work on this model though. Going to try it out now.

Nice work, could you do a monster mouth but from the back of the neck, like the skin from jenny xj9 human form

Another idea(s)
mouth prolapse (Alien xenomorph style)
Alien xenomorph style from mouth
or as a variant of the "tail pussy succubus/尾マンコ サキュバス" lora

@sevora Probably difficult to do but what about latex skin showing anatomy or something?

Also have you seen the slug girl lora on here as you might like that one.

could you do unbirthing/vaginal vore maybe? Or face to pussy tf? (faces where the vagina should be basically)

I would also love a vagina belly,

Do one where the the mouth is at the end of a fluffy tail (it’s a furry thing; like a living tail)
