Every good pet needs discipline. So you need to stop stroking for just a short while and spank your bottom.
Spank it firmly but not so hard it hurts at first. Once you start to numb start spanking harder and harder. You can use and object if you want it to go faster but don't stop until both your cheeks are nice and red for me.
I can tell you like my nails. I suppose I can let you rake your nails over your bottom instead if you'd like. Again just firmly at first. Once things get numb push your nails in nice and hard.
Don't skimp out on me. You want your desires fulfilled don't you? This is an important step in letting go to me. I can't give you what you need until you give yourself to me completely.
You can stroke yourself again while you get your butt red if you can manage. Only when you are nice and red for me we can move on.
