Uniform fetish.

I suppose there is something about having gorgeous women in uniform coming up to you and "Sir"-ing you here and there, only in real life, there aren't so many uniformed sexy babes to go around.

Although theoretically, I could have her wear the top bit of my own uniform sans bra, with a peak cap, heels and a tiny thong to match.

And of course, she'd have to "yes Sir" me to everything I'd ask of her, no matter how naughty, raunchy or dirty.
