How about you're tongue? Can you eat my pussy while your stroking that little dick of yours? Can you send me into ecstacy for hours on end? I doubt it, but atleast you get to keep stroking.
Hmmm... you've done doing a lot better than i thought you would, so i'll make this one pretty simple. 100 strokes as fast you can, you should be breaking into a sweat doing these strokes. Then stop after you're done.
Take a 2 minute break from stroking, but don't get soft.
