Just think.
Only a couple more weeks of torment, and you'll be back here at my feet.
I think you owe me a couple of ass kissing sessions before I set you free - before I let you feel some relief. In fact, why don't you kiss my ass on the computer screen. Imagine what it will feel like to press your lips against my real ass cheeks.
Bring it to the edge again and hold it there for one minute.
