Since people have been counting
Tera Patrick, I'm going to go with her. She is my 2nd or 3rd favourite porn performer of all time. Myself and three friends bought "Virtual Sex With [NOBABE]
Tera Patrick[/NOBABE]" as a birthday present for our fifth housemate when I was at uni and we all had a spell borrowing it because we all thought she was amazing. I acquired by good fortune a free copy of "[NOBABE]
Tera Patrick[/NOBABE] A/K/A Filthy Whore" not long ago when I was making a purchase of several of the Filthy Whore DVDs, and I probably watch it more often than some of the ones I paid for. Tera did scenes that will live in my memory long after I've forgotten the names of active stars that I enjoy today.
Otherwise, Maria Ozawa for looks, Asa Akira for performances, and I'm also partial to "Janine" of CreampieThais.
