My stepsister and I had a public handjob and cumshot in the car

My stepsister and I have always been close, but our relationship has always been a bit... strange. She's always been a bit too touchy, and I've always been a bit too eager to let her get away with it. One day, we decided to take our weird dynamic to the next level. We jumped into my car, parked on the side of the highway, and she started working her magic on me. Her hands were expertly skilled, stroking me with an intensity that made me lose track of time. The car was filled with the sound of her soft moans and the rhythmic movement of her hands. Before I knew it, I was on the brink, and she was there to help me over. She covered herself in my warm, sticky cum, a testament to our wild ride. It was the most public handjob and cumshot we'd ever had, and we couldn't have asked for a better way to spend our afternoon.
