Such a good girl. Don't look at me, look at him. Lick up and down the shaft, then take him all the way into your mouth. A little deeper each time, until you gag just a little. Establish a little rhythm.
Now, I want you to relax your throat, and slide him down as far as you can go. When you come up, moan for him, let him know how good it feels.
Now keep going. Think about what it would feel like to do this to you. What would it take to make you come? I want you to go at least twice as long as that.
