I'm Here To Coach You
Go ahead an lie down on your back. When the time comes you are going to throw your legs up over your head so that your cock is pointing down at your face.
When you cum aim him all over your face to get that extremely warm, gooey, lovely feeling. Of course, you could go further. If you think you are ready that is. What girl are you picturing in your mind that you are going to emulate? Does she have a big load of cum in her mouth? If so you may be ready to open your mouth when you cum and aim your cock so as much cum lands in your mouth when you do.
Did she, that girl you are dreaming of, swallow that load? Will you swallow that load?
Decide now, its almost time, and don't turn back, don't disappoint her, if she can do it, you can do it. You need to do it. You want to do it.
Say it, say what you want to do right now and continue.
