I'm not able to find any video source for this content.

Notes:

You can see infos about the release on website Wild Amateur Fantasies on the following archived webpage:
https://web.archive.org/web/20050612233514/http://wildamateurfantasies.porn
access.com/

The description gives the name of the blonde girl on the left as Katrin and also reveals the existence of a video:

Katrin is a sexy blonde who enjoys seducing guys with her girlfriend. Her special thing which drives her crazy is sucking a cock together with her girlfriend and riding it when the girl licks her pussy! Watch Katrin’s wet adventures on our full-length videos!

However, I'm not sure this is indeed the original release. Because you can also find the same pictures on other websites, for examples on the archived pages of Teen XXX Hardcore and Nubile Ones here:

And when you search for the other girl, you can find the following pages with many of her picture galleries that resemble the setting of this scene:
http://peachy18.com/t/katusha-nubileones-aka-little-becca-95145/1.aspx

Many of these galleries are not available anymore, but you can find several (archived) pages that show she used several different names for the same content - basically:

There's also an archived website on which OP's picture appears in the same photoset, but now their names are Lena and Olesya:

And then there is the following forum thread in which users discussed that they are unable to find any video source of this content and in which they speculate if the girls are from Russia or pretend to be from Russia, but live in the US:
http://peachyforum.com/t/little-becca-95145.aspx

If I had to guess, I would say that all this content was previously released somewhere else, most likely in Russia where they are from (or Eastern Europe in general). But I can't find any earlier release to prove my assumption - and I'm exhausted from searching... :-(
