Rule #1 of this challenge: You cannot slow down, or stop. You must maintain a medium/quick pace the entire time.
Rule #2: If you cum, you have to RUIN IT.
Rule # 3: Look back at rule #1. No stopping. If you cum, ruin it, and then keep going.
Rule #4: Once you ruin it you have to keep ruining it. If you cum 5 times you must ruin each one. You are no longer entitled to a full complete orgasm.
Rule #5: if you make it to the end of the video without cumming you are allowed a full orgasm.
