Bossy, devious, unreasonable, selfish -- these ladies are perfect for keyholders. I'd love to read more about that Latina gal's 'little punishment room'.
The Latina girl was based on a woman I know, who could have had me doing whatever she told me to do - and she knew it, too. She was in a relationship, but she knew her power over me, and we both enjoyed that feeling, even if nothing ever came of it. I never found out whether she had a punishment room.
