^You are new so you may not know this but there is a search option that allows users to find out if there is already a similar thread started. In this case Nina has her own dedicated thread but seeing as the last post was in 2006 than you can be forgiven for not having found it. I'm including a link to her thread as well as one to IAFD where you can search pairings for each performer. You might want to post this question in her thread. if nothing else it will at lest bring her back into the minds of other members which may spark a renewed interest in her.

This is the link to Nina's IAFD page. I checked and they don't list any movies where she is even in the same movies as Mandigo so let alone in the same scene.
