What do you think is my wife doing with her coworker in the car?

Description: Custom video. "every time her coworker takes her back home, they stop the car for some minutes and the car starts to jump. it's weird, but i guess by the way his car moves and shakes is because i think they like to do some exercise inside the car to relax before he lets her leave. that's really nice. he seems like a nice guy!"
