Gym knickers

[owlman]

Recently due to illness I have spent a lot of time in bed and began thinking about when I was a young man.
Well I remembered when I was in my late teens how I was into running, something I can't do any more due to a medical condition.
Anyway I remember sitting on the grass after a run at the athletics track and watching the young ladies playing hockey.
A lot of the lads sat and watched waiting for the time when a skirt would flip up revealing a flash of bottle green gym knickers. These were always tight around the waist and the legs but a bit saggy on the bum, and it was only a few girls who'd had their gym knickers for a few years and grown into them that had a tight bum
I remember the games mistress wouldn't let the girls leave the field to use the toilet, ' you should have gone before coming out ' she'd say and as a result it was fairly common to see at least one girl wet herself during a hockey match.
I'm sure she enjoyed seeing them lose control and eventually a few of them when needing the toilet would say that they had a loose bootlace and run off the pitch, sit on the grass and wet their knickers sat down, this obviously being less embarrassing for them, you only knew they'd wet themselves if their skirt happened to blow up in the breeze and then it was obvious.
I often wondered if any of the young ladies ever shit themselves during a match, I suppose one or two must have but I don't remember seeing it , the games mistress was a real sadistic cow and seemed to enjoy knowing a girl had wet herself, or even better was struggling to hold on. I bet she'd have been in heaven knowing one of them was running around with a full load in her knickers.
