Teen Hitchhikers is a website from the Reality Gang Network. It's long gone. I believe the network, if it is still around, is not accepting new members. That's what I've heard.
Manwin / Mindgeek purchased the Reality Gang Network domain in 2008 and used it as a pawn in their game of chess. The network was strictly gonzo porn. It was competing with their pride and joy at the time, Reality Kings. There was even an article in Xbiz when Manwin acquired the Reality Gang Network. They told the Xbiz reporter that they'd be doing upgrades to the films bringing them up from 360 p and 480 p to 540 p and 720 p. That never happened. When the affiliate money (traffic between webmasters) dried up, they took down Milf Cruiser, Euro Bride Tryouts, Teen Hitchhikers, Needy Wives, and Adult.com leaving only Big Sausage Pizza to survive. Eventually Big Sausage Pizza's videos stopped working. Manwin also did not bring over any of the photo galleries from any of the websites in the acquisition. Yes, how do you screw up an acquisition like that? Manwin did. And they, now known as Mindgeek, continue to mess up everything they touch. The best example of their incompetence is Twistys.com.
So unless you want to check free tube sites, for the partial scene, that entire scene / movie most likely is also gone off the internet. You might get lucky. Try
adultempire.com or
hotmovies.com - search for bundled films that you can purchase or rent minutes (pay-per-view) of scenes.
If you can remember any of her co-stars in the scene, you can use the iafd and data18.com to see if there is anything out there on the internet. The iafd will have links to adultempire.com and hotmovies.com. Data18 will have thumbnails of the scenes and may also have links to these aforementioned websites.
Good luck in your search.
