The cum cannon! Absolute mega-shot

How can you get the cock to shoot an extreme amount of cum? As I studied biology in Berlin for 6 years, I knew roughly what to do. One user agreed to do it. On the first day he came to me and fucked me extensively in all my holes. I licked his cock for at least 30 minutes beforehand, then I sent him home without letting him jerk off (poor bastard :-) ). The next day we repeated the whole thing, only this time I also stimulated his prostate with a thick dildo. Then I sent him home again. This time he wasn't allowed to squirt either. He wasn't allowed to touch his cock at home either. We repeated this procedure 5 times. Then came the day of truth. After all this procedure it was now planned that day that I would make his cock jerk off with my mouth. I wanted a really hot facial insemination. The cock was rock hard and I was blowing and licking so hard that I thought it was about to burst. And then it happened. The cannon was fired. But watch it for yourself. Nobody believes it anyway.
