This happened last week.
My wife and I, 32 years, have never talked much about sex. She has always been willing to fuck and likes it but talking about it always got shut down pretty quick. I was always the one buying new toys, suggesting fantasy talk, etc. She would tolerate the toys but no more.
Well this year something happened. We have watched some porn together, we've talked some, we went to an adult store together, she gets much MUCH wetter now, she has squirted a couple times and is now multi orgasmic with at least several small ones and a bigger one, sometimes a couple of big ones every time we fuck. All great.
So a couple weeks ago I bought a new toy. A penis sleeve made of real soft jelly like stuff. It's pretty hefty girth wise especially with me in it, I can't wrap my fingers around it. But it's maybe 1.5" longer than me inside. The last 2", the "head" would stay flat. She would cum with it but nothing special. So I figured out a way to fill the head and keep it stiff and wider than the shaft.
I have been out of town a few days and told her to be warmed up when I got in late. When I got home I got her revved up and put the sleeve on and W O W!
She got super wet and squishy, really loud noises, lots of hip action and squirming, quite a few small orgasms and then the loudest, head thrashing-est, hip bucking-est ogasm she's ever had. The whole time we were talking about her dirty slutty pussy, calling her a bad girl, her asking me if I'd let someone else fuck her, we were fucking for about an hour, it was great.
Then, I took the sleeve off and put my dick in her. She was sooo loose. She started apologising and I shushed her telling her I thought her sloppy pussy was sexy as hell. The sounds and feel were fantastic. I started saying I was fucking her sloppy seconds and she started moaning. I called her a size queen and had to explain what that is. We had a very deep hard kiss afterwards.
I doubt she's anywhere near even flirting with a guy anytime soon, but I think this was sexy as hell and wanted to tell someone. She's laying here asleep and I'm still hard as a rock.
