It is so hard to find fat chicks in fiction these days. Sure, having skinny characters fattened up is hot and all, but I crave the ones that keep the weight. So, I've seen some shows or anime where a character is fat for like ONE EPISODE (or like 2-5 episodes, one season tops) before she ends up drastically losing weight just to give her "more" sex appeal, as if she didn't already have any. So, I want recommendations for girls that stay fat. Or girls with lots of art in their initially fat state. Either way.

only ones i can think of from the top of my head are nikuko from oshiete yo! galko-chan and amethyst from steven universe

Try Elfuda and various other characters from Plus Sized Elf.

All the characters from Plus-Sized Elf/Elf-San Wa Yaserarenai

Inko Midoriya from MHa

Exactly how big are you looking for? Artist Albatross tends to draw gals on the thicker side, but draws a lot of futanari, too.

The bigger, the better.

Are we talking perfectly spherical, or...?

I'm not sure? What would that even look like?
