I travel a lot for work, hours at a time. I HATE being in the car so long, but lately my thoughts have been running wild and I masterbate on these trips. I unzip my pants and rub my pussy for most of the ride. When I pass cars, I slow down so they have just enough time to catch a glimps of what I'm doing.
Sometimes I even find things in the car, like a bottle, and pull my pants and panties down to fuck myself. It's such a turn for someone to see me doing it, but I always feel guilty after.
