My wife and I flew to Oregon to see our middle son and his wife for Christmas. Since we live in a small town in Wyoming it is smarter financially to drive to Billings and hop on a plane there. Yesterday we were driving home, on the interstate, when I jokingly asked my wife, who was driving, if she was going to strip naked when she started taking her coat off. She replied that she would when I did. She should have known better, I stripped everything off, laid my seat back and just sat there. Being a woman of her word she pulled over and took her clothing off too. We headed back out and just laughed about it. I was a little shocked that my wife did it as she is pretty shy. Since it has been almost 2 weeks since we had sex I couldn't resist playing with her large boobs. Doing that made my cock get hard so she grabbed it and started jacking it which got me fingering her very wet pussy. It's a 2 hour drive home and we edged each other the whole way. When she finally came she squirted all over her seat and the dash. That made me cum too and my first spurt hit the headliner with the others either landing on the dash, windows or me. Very satisfying orgasms for both of us. I'm sure the truckers we passed enjoyed the show too,
