Your cock must just be throbbing in your hands. I wish I could violate my rules and pump your cock a few times just to feel it warmth, to feel the beating of your heart. I could just touch the tip. We could say I was cleaing off all that precum. No, no that would be a violation to my own rules.
Look at what you are doing to me.
I want 5 light strokes as fast as you can and then 3 firm slow strokes. Do this until you reach the edge and then stop. Count to 5 and repeat. Do this until you can not get through the sequence of 5 light and fast and 3 slow and hard. Keep track of how man times you were able to do this for.
If you were able to do this less than 3 times I want you to repeat the sequence above 3 more times!
If you were able to get through 4-10 times I want you to repeat the sequence once.
If you were able to do this 11 or more times you may take a 2 minute break. Then I want 100 light strokes with your finger and thumb.
That was fun. The look on your face is beautiful...
