Two that immediately spring to mind ... Tiffany Walker, and a girl with glasses called Tracy from Basingstoke.
I'd been seeing a friend 'on the side' as it were, and she was going travelling for a few months; I said that I'd miss her and have to find somebody else while she was away. She suggested one of her friends who she worked with ... double act, etc, yadda, yadda. Showed me a pic on her phone ... bloody hell, Tiffany Walker!
The second one ... at a house-party with a small group of friends. A girl I'd never met before ... Tracy, from Basingstoke area. After shagging here, having a cool-down cuddle she mentioned about having done some porn flics. So naturally I started to search for them ... took about a year, but I found one or two, including one by Ben Dover.
