Hubby was at work, and I was bored, so I took my stepson for a ride in his car. We started flirting, and soon he was all over me. He pulled over, and I climbed on his lap, riding his cock hard. We fucked in the backseat, moaning and grinding. He made me cum so hard, and we loved every second of it. Now, we sneak off for car sex every chance we get.
