This is my exact niche. It's a weird intersection between vore, WG, and guro.
My favourite author has to be FredHerring since her stories feel personal and intimate in how they treat their characters. But there are plenty of good ones out there.
RalphLeCann is probably the oldest author in this area and has been writing for maybe 20 years. His stuff is full cannibal but with a focus on larger women and them sometimes gaining weight www.deviantart.com/ralph-lecan/art/One-Sizzling-Role-53003198
If full on cannibalism isn't your thing, then Komperaklause's Gretal might suite you well. It's mostly just force feeding with the implication of impending fairy tail with eating. https://www.deviantart.com/komperaklause/art/Gretel-Part-1-564500523
You can occasionally find some stuff from Food transformation artists, like this https://www.deviantart.com/veryfilthything/art/A-High-Class-Meal-Story-754573258, but U find them pretty hit or miss. Especially since they sometimes go into magic WG which isn't my thing.
I've got a whole list of decent stuff in this neiche. I might as well compile them here when I have time.
