I am going to need you to start stroking that hard cock of yours at a medium pace ........ just so that we can get the juices flowing in those nuts of yours ..... but you must remember ....... during this exam, there are to be NO accidental spurts on your part. Got it!
That means that if you get close at any point you must stop and get things under control - and by all means keep going when you can handle it.
If you understand all of this - please ..........
