Roll Them Bones
Feel your cum bubbling up inside those balls? I hope so. I want those balls swollen and purple before you finish.
You will have a chance to cum eventually. A small chance, so don't get your hopes up too high. If you do get to cum at the end, I want all that goop to explode out your penis. No pathetic little dribbles like usual. Actually what I really hope is that you won't get to cum at all. You'll be forced to put your aching throbbing member away and wait for another day for a chance to release all that pent up juice.
What are you waiting for? Roll again and do your strokes! Keep your thumb and forefinger at the top near the head until I change my mind again. Forget the clock, just do them fast this time. Hurry up! I don't have all day.
