I like them. Too few female pred voice actors though.
I know some girls on Chan boards like 4chan do such (among other things)- voice request threads are often in hentai sections.
Here on Eka's i only know of Hestia.
She Usually puts a link to her Audios to the script uploads in her gallery. If you dont know of her I'd recommend checking it out.

Tried myself on editing something a while ago.
You need to count in several different things.
Different sounds of swallowing
gulp or slurp?
Big / small stomach = Echo? Muffled sounds.
Heartbeat, breathing of the pred. ETC.
