I've only three complaints.
#1: The blonde damsel isn't properly restrained. She could quiet easily grab a fist full of that old hag's hair if she wanted and then rip some of it off.
#2: The blonde damsel isn't gagged. But that relates to complaint #3 actually (see below).
#3: The blonde woman appears to be ENJOYING HERSELF. That just takes ALL THE FUN out of a smexy blonde woman being bound and dominated by an old hag.
Other than that, awesome artwork.
