My top two are snakes and worms (and you get all different types which I like) . I quite like stories or series (like Linart's clone series) where 3 women all get eaten by a snake each (then I feel the situation is hotter because they are all experiencing the same horrible ingestion and digestion (both states are as good as each other) I also like linart and others because they depict a great amount of drool, saliva dripping down onto breasts just wish there were more pictures from her of snakes swallowing women's asses with saliva on them (I am more an ass guy than breast - and the ass has to be meaty that's why I like Shak) Though I do find solitary snake vore great as well particularly if a woman is isolated and vulnerable and fully aware that she's in great danger.
Also snakes constrict their prey and have huge coils that completely overpower the women - that the erotic idea I love that the women have no chance but I like them to struggle. Also everything is against a woman whose the prey of a snake, the snake walks itself essentially over its prey's body, lubricating it (whether the prey knows why its being covered with saliva) and then slips and slides slowly down the oesophagus passage / gullet to a stomach that might be half way - 2/3s of the way down a snakes' body. The complete ingestion just getting the woman / her plump meat its body might take an hour if not more and it would take a long time for the prey to reach the stomach... so I like descriptions of time = for within that a prey like Shakira would fully experience/ know what is coming - where she's going for a very long time before she gets there ( also once she's in the snake theres no escape - theres only one way she's leaving
(There are many other things I like about snakes as my favourite these are just some highlights )
Speaking to someone on Ayrion I am even more fascinated with snakes - with their digestion I didn't know that they almost completely digest / absorb everything from the prey, theres not much waste (if the digestion is uninterrupted. Also if Shakira as an example being 120 pounds ish the snake would use a third of her biomass 40 pounds a huge amount just to enlarge its organs - stomach etc just to digest the prey (thats what I have recently found fascinating that the snake uses a great part of the prey's matter just to be able to digest it in the first place.) Its so horribly efficient!
Others I like slug-like worm which I have seen in sci fic settings and in the Peril Comics.
I like hunter gammas how they hold a lady up by two legs with her ass in the air while they gulp down. I love Barnacle vore too from half life but htere isn't much- I did start a series with Shakira as prey but haven't got far.
So I like anything where theres a bulge, or has elastic walls of flesh to smother its prey like worms / snakes etc.
I personally don't like human voring each other, also I don't like hard vore (but I do like hard digestion) , also I don't like spiders (because I hate them in real life - I suppose everybody has a phobia)
