I lick the hell outta ass hole when given the chance. As long as she's clean and hair free, I'm all about it.
I've fucked a girl once (married, and a f-r-e-a-k) who I swear to god licked my ass and balls and cock for over a solid hour. I'm clean and hairless, so I let her eat. It was hot, very much like a domination thing to me.
