Biggest collection of vore literature is Eka, but most of it is garbage. Don't despair though, as there are diamonds among the rough.
Prinnydood is a decent author, most of their stuff is creature/f:https://aryion.com/g4/user/PrinnyDood
Lilylove is more of the same, yet doesn't update anymore:https://aryion.com/g4/user/LilyLove
This one is quite nice, and has a crocodile predator, which is quite rare.

A lot of authors put their stuff on DeviantArt as well, so you might find something decent there.
