The Indian woman

You float across the teachers lounge, listening to the low levels of chatter from some of the others and focus on the Indian woman marking papers. She's sat there completely oblivious to anything else happening in the staff room, dressed in a rather plain green dress shirt, a series of buttons up the front keeping it closed.

Just as a little experiment you click you fingers and the top most of the buttons pops open, rewarding you with a view of her rather impressive cleavage, but the teacher is still completely engrossed in her work, unaware of how much of a view she is giving you.
