Ohhhh, Hell yes.
I'd do it once a month if possible.
I was a paramedic years ago and we would have to be on standby for the drag races held in our community every two weeks. I was sitting alone in the ambulance while other attendant and race fans were about 10 feet away. Got a blow job doing that too.
Multiple times on the interstate, have pulled up to truckers and drove along side while I came.
While watching the secretary in the other room of my work study job in college.
While hunting, several times. Hunting partner was usually around somewhere.
Back seat of work truck I was riding in with two other workers in front seat.
