If you are following girls up steps it is not easy to see up a tight skirt. A loose skirt tends to flap as the girl ascends and gives a much better chance of seeing her knickers.The opposite is true if a girl is sitting, either with her legs together or crossed. A girl with a loose skirt can push it down to obscure your view. But a tight skirt stretches across the legs affording the opportunity to see the wonderfully exciting triangle of the front of the knickers.

Twice today I saw the white triangle of a girls knickers where a girl was sitting wearing a short tight skirt. The first young girl was sat on a ledge at a famous city monument. She wore a short tight denim skirt and her legs were crossed. I walked slowly past her twice and was able to feast my panty pervert eyes on the nice little white triangle of her knickers . Sadly I had no time to masturbate as I had a train to catch. However when I reached the station, already in a state of agitation and frustration, I saw another girl with her legs crossed, wearing a short tight  black skirt as she waited for her train. I walked slowly by her and again saw an exciting white triangle of her knickers.

This second sighting put me right over the edge. I decided to miss my train and made a beeline for the station toilets . I took down my trousers and rubbed my panties as I relived the experiences of seeing the white panties of these two girls. And then I cummed myself, such a blissful feeling coupled with the sticky wet warmth in my knickers.

I tidied myself up in the cubicle, went out and waited twenty minutes for the next train.
