The ride home

The next morning we ate breakfast with her family like nothing had happened, and then we headed home. Although a bit unusual, Kate volunteered to drive us, so I found myself in the passenger seat. Our son was strapped in the back, asleep in his rear facing car seat.

"I'm horny," Kate said almost as soon as we had pulled out of the driveway. "I wish I could sit on your face right now and see if you'd eat my pussy the way you ate Marcie's."

"Kinda hard to do while driving," I said.

"I know, but we'll take care of that tonight," she said with a smile. "Right now I want you to unbutton your pants and pull your dick out."

"Kate, we're driving through town," I said.

"I know, but I want to watch you jerk off for me," she said.

"Seriously, anybody driving by could see me," I protested.

"Do I need to bring up my sister?"

I sighed, resigned to my fate. She seemed to have moved on rather quickly from catching me with Marcie, I did not want to bring that subject back up again. It had ended as well as it possibly could have.

I undid my pants and pulled out my limp cock and balls.

"Good boy," she said. "Now what would make it hard? I know if I was bent over and you had your tongue in my ass you'd be hard. Although last night you really seemed to enjoy me pissing in your mouth. I was so ashamed to tell you about that fetish too! I think we could make that a regular thing. You can be my little bottom feeding piss drinker."

I was surprised to find myself getting hard as she talked down to me. She noticed and smiled.

"I am discovering a whole new Alan," she said. "Now stroke it for me."

I did as she said and started slowly stroking my cock.

"Just so you know, I'm taking a detour," she said, turning off of our normal route ontoba street that ran through the busy commercial district. There seemed to be people everywhere on the sidewalks. "And you are going to keep jerking no matter what happens."

About then a street light ahead of us turned red. We pulled to a stop while a busy sidewalk of customers passed by. Only one noticed what was going on in my car.
