My dick might have written a check that my ass can't cash..

My wife has discovered that she likes fairly rough PiV and she can take it as hard as I can manage missionary. Earlier this week we were going at it and wanted to mix things up so I bent her over and was fucking her from behind. The more and harder I pounded the more she would moan and clutch the sheets. When she started to cum I grabbed her by the hips and pounded her relentlessly.

Now this is where I fucked up... After she had her second orgasm I needed a breather. I pulled out, slapped her ass with a solid whack and said, "THATS how you fuck from behind!"

Our semi-weekly pegging session is coming up and she has been unusually excited about it. When asked why the sudden extra interest she said, "the gauntlet has been thrown and challenge accepted!"

I think she really really means it... I can't wait!
