Mistress Julia!!! I love it!!!
You're the only one besides me so far that I have heard of writing Julia-as-Dominatrix stories. I participated in a round robin years ago where Julia became a vampire and I got to write her first appearance. I kitted her up in this leather outfit, complete with boots and car-coat, and had a huge amount of fun with it. I'm sure Grayson would have found it a HOOT, given her impatience with Julia's "straight-a$$" ways.
I wonder whether the good Doctor was thoughtful enough to provide her "patient" with knee-pads? LOL!!!
