It's summertime! The best part about summer is the sunshine and the games we can play. I want you to grab a rope or shoe laces. We are going to be tying up your balls today! Tie them up nice and tight, they should be swollen like an overfilled water balloon! Good slut. Did you think we were just tying you up? No! I want you to hit your balls...100 TIMES! This is the CBT summer challenge to end all challenges. Your balls are going to be aching after I'm done with you. But you will be so thrilled when you hit 100. Try to stroke after, I dare you! As a reward, you can have an intense orgasm to drain those poor balls of yours.
