I want you to think about it while you stroke. The fact that I am the reason you are going to ruin it. That I am the voice in your head telling you exactly what to do, exactly when to fall apart. You can try to resist it, but you will not. You will ruin it for me, just like I said you would. And when it is over, all you will feel is that perfect mix of regret and humiliation, exactly how I like it.
