Let's try this game another way. This time, get on your hands and knees facing away from the wall. Spread those knees wider so your cock and balls are floating flee. Imagine you are getting ready to get fucked in the ass and you want the person violating you to reach down and stroke your cock while they are fucking you. I'm sure you have imagined that scenario many times when you were lying alone naked in bed, no?
Now, scoot a little closer to the wall and then take your ball and throw it over your shoulder so that it bounces off of the wall and immediately strikes you somewhere from behind. The goal here is to get 15 points before we move on. You get one point if the ball hits you in the ass, two points if it hits your dangling cock and three points if it scores a direct hit on your sore balls.
Go ahead and scream if the pain of this large ball crushing your balls is too much to bear.
