Ummmm, I hope you enjoyed that cos thing are going to get a lot more interestign from now on...
I think those balls of yours are feeling a bit left out so we better give them some attention!
Take one shoelace and find the half way point. Place this point under your balls and bring both ends up and around your the top of your cock and tie it off tight. Then bring the two ends around the front of your cock shaft and tie it off tight again (I want to see those veins pumping).
Now wrap the rest of the lace off around just your balls and tie both ends off.
Very nice :) That'll make sure that little thing doesn't go soft anytime soon!
I want you to take that ruler and re-open the metronome and set it to 120. Now lightly tap your ball sack with the ruler in time with the metronome until the clock on your pc changes once.
Now place a clothes pin on each nipple and repeat the previous exercise, but this time i want the taps twice as hard.
When you are done, you may continue...
