JOI Challenge Rules: You have 5 minutes. You will be stroking your cock to the sound of my voice, my burps, my encouragement. I am going to try to get you to cum before your 5 minutes is up.  Every burp is worth $10. I burp, you stroke. If you cum before the time is up, you pay double. You think you have what it takes to win my challenge, or will you be tipping me a huge bonus?
