This was a passing idea for a fun little detail in vore, which I figured could get its own thread in the end. I thought it would be interesting to see vore pics / comics / animations with preds having the reknown "ahegao" expressions from swallowing and / or digesting their prey. This means without there being anything sexual (necessarily) going on with the predator... just from the prey going down or moving inside. Doing a quick search for an example, this is very reflective of just what I mean:
Wanted to make this one about oral vore specifically; With other types it's usually sexual by nature, so this sort of thing is kind of implied and nothing special. But it would be cute and interesting to see preds getting the same expressions and simulation solely from what's going on inside their belly, or from their attempts to swallow the prey down as they keep trying to climb back up
