It is a very, very humbling device, and not only messes up your testes, it will give your psyche a nice kick in the yarbles!
This device is for the real experienced, and the young. I had it on for about an hour, with a couple that really got off of me in pain, and I was on my knees, forehead to the ground, ass in the air, then I had to "walk" around, which is impossible! you have to kind of walk like a kangaroo.
My balls were sore for a month, we never tried it again.
Today I could probably use not use it.
I just got that empty feeling in my gut I use to get while being punished. Yikes!! I need to find me a mean, mean lady...
