Quick car sex with wife

Yesterday me and my wife (33m & 30f) were heading to some friend's place for lunch. On our way my wife told me : I'm always horny when I wear a short skirt, can you stop the car?
So no need to explain that it's exactly what I did. I found the first quiet place and parked the car. She humped me right away and since she was already very wet I slid in easily.
We did our thing real quick. We then went to our friends place like nothing has happened. My wife with my cum dripping in her panties.
