(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.
