Satin pe shorts

[satinfetish45]

At my primary school if you forgot your PE kit they provided a t shirt and umbro nylon checked shorts. I use to always use to forget my PE kit so I could wear the silky nylon shorts. I use to have to slip my boner in the waist band and sneak to the toilet. I had many time locked in the cubicle wanking with the shorts.

I still love to wear satin PE shorts to this day. Have many pairs, but they are getting hard to find.

I can remember another time I accidentally wet my self at school. The teacher took me to the bathroom to get cleaned up. I was In the cubicle taking my trousers and boxers off when I heard the teacher come in and say nothing to wear only the schools pe shorts. I get excited when I slipped them on the beauty of it is that there was no lining so the soft silky
satin was caressing my cock and balls.
