Try Not to Cum B4 18 Minutes for a Huge and Heavy Flow of Nut Out of Your Balls

A tip I got from a friend was to stroke my black cock for over 18 minutes or so and see how much load of jizz I would burst out...Well did exactly that, It was not easy cause my cock was over-exited, and I wanted to shoot that creamy nut out of my balls. 18 Minutes down the line I had an extreme cum bursting feeling that put me to sleep right away
