Fist time a guy licked my wife's butt

Before we met my wife confessed that though this one guy wasn't much of a fuck, with his small penis, too quick to cum - never letting her finish, etc.
"He did make up for it by teaching me about licking my butt!"
She said he got her really drunk one time - "and really all he wanted was sex from me. Never spent time with me...just came over to fuck me, or took me to dinner so he could have sex with me afterwards."
"One night he lay naked on my big bed, spread his legs wide and ORDERED me to lick his butt!"
What did you do?
She said she crawled up between his big hairy legs, spread his hairy butt cheeks and put her face into his butt fur....and stuck out her tongue and went to work on him!
What did you think of that?!
"I though that this is SO naughty - and that I must be a real slut to be doing this! You can imagine what I was smelling and tasting!"
And then what?
"I came! While I was licking his butt - I had a huge orgasm!"
She said that they did this pretty much every time he came over to her apt. Of course he licked her butt, too - and she loved the way that felt....and she loved the naughtiness of letting a man do this to her!
I learned that she really does love having her anus licked. Once I put a pillow & towel under her hips - and 'drank' a cold beer off of her little pink asshole. She loved the sensation of me lapping that cold liquid from between her cheeks!
BUT, if you really want to see this girl get animalistic!....back up to her while she's sitting on the couch and stick your bare butt in her face and ORDER her to "lick my butt, Kathy!"
She will start growling and and grunting and making the most unladylike noises as she excitedly sticks her face and tongue between your cheeks! Afterwards - she wants fucked HARD!
I guess I should thank that guy, even though she says he was a lousy, unsatisfying fuck... "Thanks James!" for licking her butt! and getting all of this started!
