Hide behide some stalagmites

You decide to dunk and hide between some stalagmites just in case he is one those bats who uses supersonic to see, and hope that he won't be able to tell that you're there. Your plan worked. The bat flys of as you still hear the screeching due to the echoing of the cave, but you can tell it's further away from you. You try to get up but something has taken a hold of you. Try as you might, but you don't have enough strength to get away. Then you feel something wiggle it's way into your ass, it's smooth and slimy so it has no trouble getting in. You turn around and to your horror, you see some green slime make it's way in you. Before you could do anything, it finished making it's way in you. You try to push it out, but that just strains your ass. Whatever was holding you down isn't there anymore. Looks like whatever made it's way into you is staying in you for awhile. At least, you hope it's just for awhile.
