Seriously you've never face fucked a girl? Maybe my explanation was a bit off, lying down face up
Lie her on her back with her head over then end of the table so her face is upside down.
You fuck her mouth like it's a pussy, take your cock out let her suck your balls, when you're ready to cum take your pick, face, titties, mouth.
You haven't experienced much by the sounds of things.
