Base model is Artofura, some fury model merge of illustrious, it feels like it understands vore out of the box a bit better than WAI illustrious.
Base model is only part of the story, more important is masked regional prompting and a convenient "Internal Vore - Internals" lora from civitai.
the style is just a zyugoya lora

Let me try and explain the technique with a sloppily whipped up image:
I use reforge and the mask mode of the regional prompter extension.
Mask mode lets you draw the regions that a prompt needs to be applied to.
in my experience(and extension version) region 1 seemingly gets skipped so i just draw it tiny in a corner somewhere.
Region 2 is the general area I want the vore cutaway made by the model.
Everything before the ADDCOL in the prompt is the main image and after it is what to be applied to region 2.
it's never a hundred percent match of the region but in general it adheres to drawn mask.

Without the "Internal Vore - Internals" lora, vore focused artists might still be good at the cutaway with just regional prompting, but non-vore artists become much harder.
regional prompting still needs it to make sense to the base model that something should be put in a specific spot, and the lora helps lower that threshold (and introduces the noise processing to draw a stomach).

I once tried this kind or regional masked prompting with Comfy but just couldn't get it to work.
