What is it about white knickers this year, they are everywhere.  I was off on the forty minute journey by train to my daughters when I saw a girl in a tight short skirt sitting in the station concourse. She was chatting to a friend and did not notice me looking up her skirt at the white triangle of her panties. I slowly walked past her no fewer than four times until I was so agitated and aroused that I had to zoom down to my usual station toilet, pull down my own tros and panties, and masturbate until my release washed away my pent up frustration. I missed my train and had to wait twenty minutes for the next one.

On my way home several girls who had clearly been out on a celebration boarded the train. There were no seats left and one girl sat on the floor with her knees tucked up. I could see her white knickers underneath them. I got an especially good view right up between her legs when she had to part them to stand up again to alight from the carriage. I was unable to wank there an then on a crowded train so I popped into the park at dusk on my walk home and sat on a secluded bench to do the deed.
