You still don't quite understand. Just because you've been a good little slave doesn't mean you are allowed to see me. You're a slave, you don't deserve to see such a beautiful woman like me in the throes of passion. So, as a partial reward/punishment, you will stare at my feet while I get myself off, just out of view. I'm so close, you can see my toes curling, my panties hanging from one foot. It feels so good, and the fact that I'm denying you makes it feel even better.
