You get to imagine just how these girls got into this situation, and what EXACTLY's being done to them
Here's how I see it:
The concept of the 'Barnacles' from the Half-Life game series inspired me to draw this, with a few modifications:
A primary tentacle makes it's way through the victim's digestive system (entering through the mouth and emerging out the anus, or vice versa), all without tearing their insides apart. This is how it initially catches the victim and 'reels' her in!
I like to think that all that slimey substance is some kind of aphrodisiac that get absorbed intot the skin, resulting in good times all around!
This work is probably not as good as my "Cave Vore" drawing, but I'm still learning, and practice makes perfect ^^
If you were one of these girls, and you had a choice, which way would you like to be 'vored':
Like the girls hanging, or the girl lying in the bottom left?
Hope you like
