I turned around and was about to apologize to Grammy but she had stepped back out the door. I pulled the curtain closed on that end and then just stoo... there, water pouring over me. I was puzzling through the fact that she had stood there looking at me for several seconds and then just left, when there was a knock on the door. “Bryan, I need to… well, I need to use the restroom, I hope you don’t mind.” Grammy said as she stepped in and walked over to the toilet.Turning to face the spray, I saw. She lied down on the bed and I was rubbing iodex at her back and she seemed to enjoy it. After 3 to 5 minutes I asked her if she is feeling better. She replied back “yes” and also asked me to rub a little up, so I did but it was touching with her blouse. I told her that her blouse might get stained due to medicine. She turned back and told me “ok I will take off the blouse” and she started undoing her blouse.Oh my god! I could not believe it, she took off her blouse and she was wearing a black. “Fuck!” she yelled as her pussy started to convulse around my fingers. Moments later, she climaxed and she started to squirt. Oddly, my initial reaction was “Fuck, my mother’s car!” but then I remembered this was a fantasy and I was able to enjoy the feel of this tight-bodied hitchhiker’s pussy quivering around my fingers.As soon as the final wave oozed out of her, she slumped in her seat and started panting heavily. I still had no idea if she had been a virgin upon entering the car, but I. This went on for quite awhile.Susan was close to an orgasm, when Jim pushed her off my face commanding "That's enough of that for now I don't want you to come just yet." "Yes master" Susan said breathlessly. "It's time I get a bit of service from this slut" he said as he pulled my arms over my head and brought my body to the edge of the bed. My head fell back and could feel Susan's grab hold on both sides. Jim then stood over my face with his large cock and balls in my face. It was the first.
