MSQueenEvil, I love your posts!
As a Domme, I adore CBT and use it as a form of punishment when slaves do not pay me the full respect that I deserve. My favorite is pulling the balls of one of my little piggies as far forward as possible (when they are on all fours and spread) and a HARD smack to the taint. When slaves flinch at that I want to work harder. I think CBT is perfect for slaves who violate chastity rules, but I have yet to come across that.
