After she finished her orgasm and had gotten back up I couldnt slide my creeper out from underneath the car. So I slid my sweat covered back along the...wooden platform until I was clear of the car before I sat up. My wife had my shorts around my ankles so I stood up and pulled them back up. Upon inspection of my creeper I found that both of the casters on that end had been broken from the enormous pressure that we had applied to it. We were still laughing about it when a friend and his wife. He suggested I look into erotic stories. I was so naïve that I had no idea they even existed. So he pointed me to a site. I asked him how he knew of it and he confessed that not only did he read that site on occasion, but he surfed the net to look at naked women. Since I wasn't interested in sex he would look at the pictures and have a date with his hand.That was insight into how long I had let things go. I didn't want our marriage to fail because I didn't try, so I began reading. The stories. "Which one?" wondered Steetch."The one with the fourth dimentional conversion- the Poincare Conjecture. And I already know your next question, I invented a new process which I call Hypertensive Calculus. It takes a quantum shortcut- you would be surprised at how acurate a truely random output generator can be. You wouldn't think that flipping a coin would give you an accurate mathematical output, but as long as you never know if it was heads or tails, then plugging it into the equation gives. I mean, it was just really soothing, the water splashing over me, the rough swish of the cloth on my skin. I got really relaxed and I think my cock even started to soften a little.But then I felt something else. It was Aunt Sandy's erect nipples tickling my back, and then her warm body pressed up against mine as her hands slid around my waist. My hard-on sprang back to life."Oh, David, this is going to be a day I'll never forget," she said, and she started to slide down. Her hands brushed.
