Last Christmas my wife and I got pretty ...... and she ended up straddling me on the sofa, riding my little cock like a woman possessed - then at one point she groaned "I want a cock in my ass". I was dumbfounded - my little wife does not come out with such things - so I expounded on the theme - "you want a cock in your ass right now, as you're riding me?"
"yes, I want a big cock in my ass, riding me while I ride you. I want two cocks in me..."
Since then, she hasn't mentioned anything like it again, but it was a glimpse of what goes on inside her pretty little head when she lets down her inhibitions
