I fucked my mother in law on a cross country road trip. My wife flew ahead of our move and I had to drive with my mother in law. First night in a motel she came while I was showering “accidentally.” While I was sleeping she woke me up and sat on my cock. Rode me until I gave her a big nut. Next day she pretended nothing happened until we got to the next hotel early. We checked in and started fucking immediately. Same thing the next four days. The last day we took our time and pulled over a couple of times to do it in the car.
