Blynch
When you tightly tie a thin string, or wire, around the base of your ballsack, then pull the remaining line upwards until it is taught and your balls are suspended. Continue holding this position until you cannot handle the pain, or you climax; whichever comes first.
Can you swing by the hardware store on your way over, and pick us up some twine? Nathan and I are going to blynch later tonight after my parents fall asleep.
