In case you're not familiar with that phrase, Im referring to when the WOMAN finishes the guy with her hands/mouth/tits. Nothing ruins the mood for me more than seeing some dude jerk himself off to finish.  

On screen or behind closed doors, who are the ladies that do the most of them and/or the best at it?

Some of my favorites are:

Miko Lee

Daisy Marie

Marie Luv

Lacey Duvalle  

Havana Ginger

Caramel

Jazmine Cashmere

Mika Tan

Asa Akira

Julia Ann.  I think she has been the best finisher in the biz for a long time.
