Ok here's the deal. An old friend of mine had used self hypnosis to cause himself to cum every time he saw another cock cum. He's bi and was more than willing to let me see it in action to prove it and to my surprise it worked.
He came 10 times and never touched himself once.
I really want this file but I can't find it anywhere and his computer crashed last year so he doesn't have it anymore either. If anyone knows where I can find it please tell me.
