You lose yourself to the experience as the cave tentacle makes repeated trips into your womb to retrieve all the spider eggs. So you weren't paying attention when the tentacle once more enters your vagina but this time it doesn't leave. You're too busy moaning in pleasure to notice as the tentacle begins to pump a strange cold liquid into your womb.

The sensation of the cold liquid inside your womb snaps you back to reality. You look down in shock as you see that the liquid being pumped into you is starting to make your belly bulge out. You moan in pain as the tentacle keeps pumping more and more of the strange liquid into your womb until it looks like you're 9 months pregnant with quintuplets.

The inside of your womb begins to tingle oddly then the tingling turns to pain as you realize that the liquid is digesting you from the inside! You struggle with the tentacle to try and pull it out of your vagina so the digestive juices will drain out of you. But no matter how hard you pull at the tentacle it remains firmly anchored in your vagina.

...

An hour later all that remains of you is a gooey soup on the floor of the cave. A small mouth opens at the tip of the tentacle before it starts to slurp up the soup.
