According to Tera Patrick, who talked to Black Book:
So which of your fellow female pornstars gives the best oral sex?
Savannah. Oh my god, Savannah is amazing. I’ll always remember the first time I ever did girl on girl with her. You know who has the most amazing eyes when she looks at you and fucks you? Felicia. She is so gorgeous. It’s just like, will you marry me? My dream girl that I’ve never been with, that I would do anything to be with, is Belladonna.
