Or they use a spray bottle of "silly string" (you know the stuff that used to catch on fire over the kids birthday cake candles) anyways they hook up a little nozzle (like the wd 40 cans) only longer... the guy holds tight against his dick away from the camera... and when the director yells cumshot, the tech squeezes the nozzle :D It shoots pretty good and thick, and they can do great slow-mo's
