If you are searching comics for KO scenes, there is an invaluable resource for you at http://sleepycomics.com/comics_searched/. Basically, I keep a list of all comics that I've searched. There is a good chance that if a comic is on that list, that all of its KO/Bondage scenes were found. This list is updated daily.

Now I may miss some stuff here and there, but I'm generally pretty thorough.

Also, before searching a comic book, do a quick search for the title. I may already have scenes from it, so don't waste your time!

Hope this helps. I'll sticky this so people can see it. Please ask any questions below.
