I had a job where i traveled to many cities in Midwest primarily in the summer/fall.. I would jerkoff and edge whenever weather and traffic permitted . in order to better use my time I would usually travel between cities late afternoon & evenings. I figured distance in number of cums per trip not miles or hours.. Minneapolis to Chicago 3 cums Indianapolis to Columbus 2 cums Minneapolis to Sioux Falls 2 cums KC to St Louis 1 cum, Cleveland to Detroit 1 cum Etc... later on as my territory got bigger I flew more but still managed a lot of one cum trips in the rental car.. a few times I brought it back with " Ice cream" stains on the seat :-)
