if you want to play with stable diffusion try this
https://nmkd.itch.io/t2i-gui
just download and run

for the hentai guro images you probably will need to download specific image training data but i don't see any guro models around.

I did not tried "gorifying" things but it has inpainting function where you mask part of picture and tell it what to draw in that area.

Anyway, things work pretty badly and we need to wait for someone to make better GUI than that
