Tie your balls so the are seperated. Then attached a 2 litre bottle of coke and do 10 jumping jacks.
I was finally able to attempt this assignment. Of course I failed miserably!!!! I was only able to do 2 jumping jacks before the pain was too much for me.
There are more pictures in my album. Hope you enjoy.

Tie yourcock like this picture, but than add rope so it's like a jock. Make it thick so the rope goes around your ass like a jock and holds your package in play. Must use this as underwear for 8 hours... don't get hard
