Good time

I fucked my wife in the ass last night. Only the second time in the 9 years I've been with her. The best part was it was an unplanned, in the moment ass fucking. I was hitting it from the side and I told her to spread her ass (normally she doesn't like this but when she's really into the sex it turns her on) and she's says, "You can try it but no promises.". I couldn't believe it, out of the blue she wants to let me fuck her ass?! Long story short 2 minutes later I'm balls deep in her tight asshole listening to my wife moan what a little slut she is! She REALLY took a pounding. I kept waiting for her to tell me to stop or slow down or something but all she said (in a mock concerned voice) "Oh no! What if I'm one of those girls who like it? What if I like that big dick in my ass? What will we do then??"
It was right about then I came, balls deep, in her ass. What a fucking Thursday!
