If i was her my mouth would have been open and my tongue. But I do love a facial, it's good for the skin after all (at least that's what all the guys tell me!!!) ;-p
I know what you mean, sometimes I have my wife lay down on the bed, and then I stand over her and jerk off while aiming my cock at her face, it's a fun way to jerk off, and it makes for a nice facial shot
