XXXL sperm explosion - secret trick?

Oh my God! What was that fountain of cum?! That was really mega cool! I got a lot of cum out of it. Ok, I tested a secret trick and I have to say, the result is really impressive. Of course, there are several things involved. I sucked the cock really hard, massaged it and fucked it with my wet pussy. I don't want to give away what follows, you just have to see it. But I think you can do that too! Or maybe you know the trick and have already cum so hard? Please don't tell me in the comments ;-)
