(Preface: I was driving my mother's best friend to Florida and we made sweet love on the second night. We are now starting our third day on the road)
After waking up with Muriel in my arms, we decided to shower together before hitting the road. My dick was at attention and she grabbed it and led me to the shower. Once the water was adjusting, she lathered me up. She paid special attention to my cock. I told her to turn around so I could get her lathered up also. I took the shower head from the saddle and rinsed her from top to bottom. I then started to soap her back as she pressed her ass against me. My cock was between her legs as I soaped her tits. My hands moved down to her bald pussy and I soaped it up. She took the shower head and starting spraying it on my cock as it stood out between her legs. She knew where she was aiming as we both came together. She turned to me and said we should hit the road so we can stop sooner this afternoon. We toweled off and her last instructions were no underwear. I smiled and agreed.
We loaded the car. Muriel was looking good in her shorts and a halter top that tied around her neck. I had on gym shorts and a tee shirt, that's it. Once on the road, Muriel started to tell me stories about my parents, her husband and her. I mentioned earlier about them skinny dipping with my parents. From the way she was going, I figured I was going to hear more.
About an hour into the ride, she told me that my cock was as nicer than my father's cock. I asked if she fucked my father and she informed me she did, often. She also informed me that my mother fucked her husband. Again, TMI for me. She said that it happened after the skinny dip and they continued to do it for years when they went on vacation. She said my mother and her would put on a show by fucking each other for their husbands.
As perverted as it sounds, my cock was now standing at attention. Muriel was delighted that I was turned on buy the story of them fucking my parents. She reached over and pulled my cock out of my shorts. I was getting a great hand job while driving down the expressway. I told her that it would be nice if she took her top off while we where driving. I thought the truck drivers would like the show. So there we were. My cock was busy being pumped by a sixty year old woman with her tits hanging out while truck drivers honked and flashed lights.
Muriel was so turned on, she removed her shorts, got on her knees and started to suck my cock. Her pussy was literally sticking out the window of the car. Now the truck drivers were lining up for the show. I would speed up until I got to the cab of the truck and then slow down to give the driver a view up her ass and pussy. In the mean time, I am getting the cock sucking of a life time. I finally shot my load into her mouth. She swallowed and then turned around so I could finger fuck her to an orgasm. I slowly put a finger into her pussy until I had four fingers pumping. My thumb rubbed her clit and soon she was bucking and screaming for more. This went on for what seemed like miles. Next thing I knew, we had arrived at our exit.
