Syringes, pumps, tubes, fake internal cumshots and spontaneous oral combustion. The lower end companies have been padding their product with this shit for years.

For all the gadgetry involved in saving a scene I have yet to see a fake pop shot that looks even remotely believable.

What's truly frightening is that someone at Vivid or its ilk is probably in the process of splicing together a 5 hour fake cumshot compilation dvd. And some poor fuckers won't even be able to tell the difference.
