Certain that I've see such but have lost track of it. A picture of Kim Possible, grown huge with muscles, possibly a futanari, looking down on a regular sized Ron Stoppable and wodering if he is a screamer.

Thanks for any attention that you've spent on this. I did finally find the image I was thinking of. It wasn't quite as memory had it and it took looking through thousands of files before finally finding it. I'll try posting it on the site but it may not work as there may not be enough nudity.
