Nothing...until...

...The feeling had started up again, that mild agitation...she couldn't put her finger on it and it was starting to drive her crazy, Anna carefully dropped her skirt down beside her feet, the light fabric made no noise as it made contact with the solid wooden floor of the classroom, then Anna looked down at herself, perplexed at what could possibly be causing her any further harassment.

She was already bottomless, her bare rear sat firmly on the plastic chair...maybe that was it, it wasn't her skirt at all, she tugged on her shirt, the hem was slightly irritating, it might not be the thing causing the problem, but it very well may be linked to it.

Only caring about removing the irritation Anna went to work, she carefully removed her tie and placed it on the desk, then set to unbuttoning her shirt, quickly but carefully, soon her shirt fell free, revealing her chest and bra...not wanting to waste time Anna let the article of clothing slip off of her shoulders, before letting it fall down to her sides, she twisted it around to her front to inspect it...maybe there was a rouge string...or tag, that had gotten caught in her skirt? The idea was unlikely, but she was at her wits end at this point...
