They appear to be from Titten Auf Spermasuche (2001) based on some random "unknown" model list I saw that had your picture and the one I attached. I am not quickly finding the video source to confirm this claim (found the source, but it's going to take a while to download it to see if they name models), but the back of the DVD case seems to show her on it.
The model list for that DVD (no idea if complete or correct) seems to be Betty Extreme (not her), Jana Boleoka (also seeing this spelled as Boboka), Claudia, Kathrin, Sarah, Nadine, Sonja, and Tina.
Update: I skimmed the DVD and it doesn't list model names. Her scene is just a solo video with some light masturbation while the rest of the DVD is your typicall GGG stuff.
The IAFD entry for this DVD doesn't appear to show her but it also doesn't list Betty Extreme who is in it so I can't tell you how accurate it is even with the listed models.
