The vid is not fake. There is another video of the same guy from the front shooting the load all over his stomach. The amount of jizz is RIDICULOUS.
These 2 videos were taken from a website about testicular cancer. This guy's balls are the size of a cantaloupe and his semen is all yellow and sickly looking. He's definitely suffering and milking it is part of the process. You can find it on Kazaa or Limewire.
