You know the rules. If you jerk off until you cum, you have to eat your mess. It's as though your cum is useful to anybody but yourself. And yet you're still resisting. You're still flushing it away or spurting it into a tissue. So now you have to pay the price. And the price is, you'll be eating your cum for the next seven days. One way or another, you will become addicted to it. In fact, you'll learn to love it so much, your cum won't be enough.
