Not her boss, but her teacher (but the same "hierarchy" applies).
She was taking a class a few years ago (I wasn't her boyfriend then). Her teacher was one of those dudes who treats men like shit but, to women on the other hand, he was very flirty and nice.
He was not quite attractive but not ugly (according to my girlfriend) so most of the girls didn't enjoy his compliments; however, the ones who pretended to like him got better grades. She noticed this and began being flirty to this man.
She would tease him from time to time like this:
- Pull down her pants a little before entering to his office so her undies were visible.
- Dropping things to the floor to pick them up immediately while arching her back to make her ass look bigger.
She confessed me that she loved to tease him. I asked her if she ever noticed his boner but she said no (maybe she did, only she knows).
One of the last times she went to his office, he was looking at her cleavage and said something like: "your friends surely love you for wearing blouses like this". She got a little turned on and pulled down her blouse a little to let him see more.
My girlfriend has kinda' big aureola (not exaggerated, just large but withing the normality); so even if she didn't pulled her blouse down a lot, he could see some nipple.
She got a very good grade, of course!
