Came across the helpless tag while doing a little cleanup on the sex tag, and I wasn't sure of making a wiki page for it in case people would consider it a superfluous tag. This kind of situation commonly occurs in the restrained position, so wouldn't it be redundant to use both tags for every time a character is bound up? Or are there other instances worth populating the helpless tag with, or is the facial expression and situation what's notable here?
I also know there's the Save Me... pool which would be along the same vein.
