Today I am going to properly teach you how to suck cock. I got a 9 inch big, thick black cock for you to practice on tonight. You need to warm up properly by licking the balls and playing with the tip. Go ahead and start doing that for me right now. Mmmm it tastes so good doesn't it? Now let's see how far you can shove it down your throat! Yes, take it all the way down there I want to see you gag. If you do a good enough job, then maybe I'll take you out for the real thing.
