I can't believe you just let me convince you to get off by rubbing your body up and down the corner of the wall! You will do anything I say!
Now go find a chair and stand over it. Take your hands and grab the top of the back of the chair, put one leg on each side of the chair and arch your back so that your ass is sticking out in the "I want to get fucked in the ass" position. That's it, show me that you want to get fucked in the ass!
Now, take your left hand and start stroking your cock, all the while you are sticking out your ass. For the next few minutes, you are to stroke your cock for 20 seconds, then take your hand off of your cock and rub your cock against the chair for 20 seconds, and then start again with your hand.
You are to do this until you can reach an edge.
