Some time these things just happen
I was on my way home from work and sitting in traffic on the motorway. I don't stay too far from the office, I was thinking about getting home, what to feed the kids and how my husbands day went.
I glanced in my mirror and saw quite a nice gentleman in the car behind me as we just travelled slowly in the traffic.
Without noticing I found my hand creeping up under my skirt, did this guy just set me off?
I slowly worked at rubbing myself through my pantie, I moved my pantie to one side and started gently just rubbing myself. This went on until I got home, I parked the car and walked into the house and went straight to the bathroom and rubbed myself to a great orgasm. I entered the kitchen as if nothing had happened and carried on with normal life, this was a great way to end my day.
