Bump, because I just found the video of it. I know the original link is banned now, and I dunno where I found it, but it's in a video called "Cum soaked gang bangers 1". It can be found on adultrental.com
It's a scene were two women are buried in the sand (Houston is one of them) and a big line of guys form along the beach waiting to jerk off onto them.
It's hilarious :1orglaugh
