We had one more stop to make, and Carolyn just sat quietly on her side of the car during the ride there. When we got there, she said she would wait in the car while I went inside for the wine for dinner.
When I got back into the car, I immediately noticed that Carolyn had slipped off her jeans. She was sitting there in the briefest, turquoise panties. She just smiled at me without a word, and I just looked at her in disbelief, swallowing hard. And getting hard again.
As we started for home, Carolyn's hand was back to my crotch before we had even gotten out of the parking lot. She had my cock out and had resumed her stroking before we had gone a block. This time, she was not slow and deliberate, but obviously had a mind to make me cum before we got back.
I started to protest. I started to stop her. My mind told me to stop her. My cock told me to let her go. My cock won. As I drove, she worked me masterfully, bringing me closer and closer, at a gradually increasing pace. I could feel a massive orgasm building in my balls. I basically lost sense of time and space, and as I began to cum, I realized that I was turning into Ellen's driveway. One shot of cum hit the steering wheel, while the rest just poured down my cock and onto my pants. Carolyn started giggling, and licked some of my cum off her fingers. Somehow, she had her pants back on already. She threw open the car door, and in a second, she was out of the door, running toward the house, laughing. I spent a few seconds just trying to process things, before it registered on me that I was sitting with my cock out and cum all over the front of my pants. I quickly put "little Ron" away, and thanked my lucky stars that I had on dark jeans that didn't show the wetness clearly.
It took me a few minutes to gather the groceries and wine and my composure and go into the house. I was very aware that I had the smell of cum about me, but no one else seemed to notice. Carolyn went out of her way to ignore me the rest of the day, and things were uneventful. By the time I went home my pants were nearly dry, although things were very sticky and messy within my underpants.
I had to return home on Tuesday, and I had a lot of work to do on Monday, so I didn't think much of Carolyn during the day Monday. I was getting a lot done, but about 3:00 in the afternoon, my cell phone rang. It was Carolyn.
"Uncle Ron," she began, "me and my friend Cindy are having a handjob party this afternoon with some of the football players. I think you would enjoy watching it."
I knew I shouldn't. Messing around with a bunch of 18 year olds was nothing but trouble. But almost as if I was listening in on a conversation of others, I heard myself asking for Cindy's address and directions. Carolyn told me to be there at4 o'clock. I said I'd think about it, but I knew I would.
