Hot wish I knew, bump.
Becky, I believe the beautiful dark haired brunette in black appeared in the dancing bear episode "Ballroom Blitz." In the video she sucks and makes the guy cum in her glass. Here is a link with a pic of the girl I am talking about.

Not completely sure if it is the same girl, but there's a strong resemblance (same eyebrows, hair is straight in dancingbear and curly in the other pic, etc...)
