OK this sounds kind of weird but my fantasy originated from a argument between two mature female teachers at my comprehensive school.
The argument was over a vacant class room, both Ladies were under the impression that they had the room for the next lesson and neither would back down, instead they bickered and stood their ground, neither refusing to give an inch.
I never actually saw the outcome but was told that Mrs Booth was given the room instead of the senior ranked teacher Miss Mastersonn, a decision (so I was told) that totally shocked and belittled the senior Miss Mastersonn but elated a gloating Mrs Booth, and in front of her many pupils.
Anyway, my fetish was fueled by the fact that the tall leggy Miss Mastersonn would often wear sheer black or navy nylons and would often dip her long narrow feet in and out of her heels while sat lecturing her pupils.
My fantasy always involved a gloating Mrs Booth tickling Miss Mastersonn to humiliation in front of a full class, her long nylon clad feet displayed for all to see.
I don't have any photos of the two senior teachers but the nearest comparisons would be Canadian author Alice Munro as sly, wily Mrs Booth and British TV presenter Angela Rippon as the tall, powerful but oh so ticklish senior mistress Miss Mastersonn.
Google their images if you have a minute, the similarities are quite staggering.
It still gets me going now, some twenty five years on, imagining tall, superior bad assed Miss Mastersonn getting owned by her foxy old rival.
OK I'm a weirdo
