I have tried to get my wife to flash her tits to truckers.  Have only ever gotten her to once and he pulled out his cell and she put them up.  I wish I could encourage her to do more and show it all.  She just won’t do it.  
I did get her to do this, this past weekend.  But everytime we would pass a truck she would cover up.  Drove me nuts but it was still hot.  i was able to pace a trucker while she was covered up but if he looked down he would have seen her cumming as she came really hard on this toy we picked up at a Walmart of all places.  Thought I got it on vid but must not have had the vid rolling.  Hard to film while driving.
I would like to pace truckers with her buck naked, legs apart showing everything.  If she would only cooperate - dammit. Lol.
