Kristina Black and her various aka's are dangerously common names.
The one who was also in the two listed VMD films and various Private video's appears to have been born in 1975 (according to the Private website, XXX Relations, www.europornstar.com etc).
If this is correct she would be too young to be in 1991's Die Spermabullen.

Hello John. I can only offer a little help regarding your post.The video box credits include Christina Schwarz which egafd lists as Kristina Black.Perhaps if someone can post a picture of Ms Black, we may be able to solve any confusion?. Regards Heron

I think John.h2 could be right, Kristina would have starred in her early movies in the late 90's.

Additional movie info:

The pictures and info in these links by Hitman are of an American starlet, who also used the aliases Scarlet Fever and Taylor Sands. Here is her IAFD page.

Kristina Black/Krisztina Schwartz is a Hungarian girl of the mid 90s. Lots of Private videos and some Euorpean fare. One that hasn't been mentioned on the egafd is an Italian video called Una trombata megagalattica.

Well spotted Walter Burns, thanks for clearing that up.

American Kristina Black - born 1982:

So the Die Spermabullen Kristina Black needs a different entry.
I haven't checked the video but on my database for the video I've spelt her name Christina Schwarz.
