As a spanker, I have to agree that the over the knee hand spanking is the best! I love to see those pale white cheeks gradually take on some colour; when they are a nice rosy red, and I can feel the heat rising (and the wetness running!) - ummm, it's great!
In case of extreme provocation, I have been known to use a slipper, but only in short bursts. As much as she likes being punished, I like the feel of my hand on her skin, and being able to stop now and then to run my fingers up and down her crack, coating them with her moisture, and making her lick them clean ...
and NOT allowing her to come! Oh god, where is she ... I'll be right back
Okay, where was I? Oh yeah - now she wants me to use a leather belt, but of course, since she asked, I won't do it (hee,hee,hee). I will sooner or later, but not when she is expecting it. I have to admit, most of our play is built on psychology rather than physical punishment; in her professional role she is such a control freak that it's wonderful to take that away from her, a layer at a time, until she is begging for what she wants.
And the ice & wax thing? We use ice, then wax, then ice.
Looking forward to getting to know you all,
