I second that "Monica_Potter" pick.
I'd like to get one from Julia Roberts. Killer Smile + My Dick = Heaven.
Anne Hathaway is another one. Great Smile.
Scarlett Johanssen, too.
I'm surprise no one has mentioned Meagan Good. If she doesn't have the best pair of DSL's (Dick-Sucking Lips) in the world, I don't know who has.
Kerry Washington is another one with a perfect pair of lips and a breathtaking smile to match.
Who else . . . ? There's Rosario Dawson. Great big smile . . . full, luscious lips . . . yum!
Of course, Angelina Jolie would look amazing working a cock.
Oh, and Brittany Murphy (God Bless the Dead) . . . her lips were pretty amazing, too.
Michelle Pfieffer . . . Eva Mendes . . . Liv Tyler . . . the list goes on.
