I smiled as I heard the word Master come from your mouth, I knew then that I had partially broken your will, but I also knew that there was still a long way to go before I had completely broken you, now I decided it was time for a little reward, I bent farther over you, I removed my arm from around your waist and moved it up to your breast, I started to gently stroke your breast and play with your nipple, it didn't take long before I could feel you stop resisting my and a sigh of pleasure came from your mouth, when you relaxed I started to gently wiggle my fingers around inside of your ass, your ass began to adjust to my fingers, and much to your surprise the feeling became pleasurable. "Listen closely little one", I said, "remember I told you earlier that the most important thing in your life will be your desire to serve and provide pleasure to me, well unfortunately for you a large part of my pleasure is your pain, if you think it is painful for me to have two of my fingers buried in your ass, just imagine how painful it will be for my cock to be buried balls deep in your ass hole, and I can guarantee you that my cock is a lot thicker and longer than the two fingers I had inside of you now. Your desires and wishes mean nothing to me, you are mine to do whatever I want to with." To prove my point I spread my two fingers apart forcing your ass hole to painfully stretch open, I grabbed your nipple between my two fingers and squeezed the sensitive little nub hard.
