On a train this lunchtime when a schoolgirl with dark sheer tights and a very short flared skirt embarked. She sat down the carriage from me so I was unable at that point to look up her skirt. However she alighted a couple of stops later. It was not my stop but I knew there was a long steep flight of steps, so I followed her off the train.The girl and I were the only persons on the steps, so l was able to creep right up behind her, bend forward, and look up her skirt. I was rewarded with a wonderful sighting of pink cotton knickers under her sheer black tights, and was able feel myself through the hole cut in my trouser pocket, and through my own silky panties, whilst gazing hungrily at her panties, all the way up the steps.

She left the station and I returned to the platform. My agitation and arousal was so strong that I got out my penis and wanked myself off in the empty waiting room, and my cum trickled onto the floor. I returned home by the next train and wanked myself off again as the schoolgirls pink knickers were still so fresh in my mind.
