You are being such a good pet. I'll give you another treat if you do one more thing for me. I'm going to show you my pussy for being so good.
I want you to get to the point where you think you might climax and hold it for two minutes. It sounds tough, but think how it will feel if you can do that in my pussy some day. I'm going to train you how to fuck me for hours while riding the edge. We need to start small though don't we?
Hold off that climax for two minutes then we'll look at the next picture of your wife. After that I'll give you the extra special treat of showing you my pussy for the first time.
