Starts normally

Margaret's day started fairly normally with her first class, though in the middle of the class she stopped for a ten minute rant when a student arrived late wearing a tube top and mini-skirt, and with her hair very messy.

After ten minutes lecturing her students on why they shouldn't look like they just got out of their hooker job and should stop showing off their bodies to men, she got back to class, though her students weren't very enthusiastic after the lecture. Following this, she continued, though continued to feel her underwear uncomfortable, though she didn't dare itch it in front of her class.

Adding to it, despite her best attempts to not think about it, sex was slowly starting to fill more and more of her mind. Margaret mentally cursed her younger sister and her antics, but the best she could do was try to ignore it till the end of the period, which was only a few minutes away. However, one of her students seemed to notice her discomfort.

"Miss Snead, are you alright? You seem a bit odd today. Maybe you need a break. You know, go out, find some guy and have a little bit of fun with him, release your urges", the student jokingly told her, and the rest of the class broke out in laughter as Margaret's face went red.

"That's sexist, young man, and you should be ashamed. Any more of that, and you will find yourself in detention", she warned, trying to use her usual stern voice, but failing with how embarrassed she was feeling from the remark. She had no idea why it affected her so much, but the joke disrupted her flow for the rest of the period. Luckily she had no class next hour, so she could try to figure out what was wrong.

Once the class left, a few giving her odd looks, Margaret took a minute to gather herself before heading towards the teacher's bathroom. Once she was in one of the rooms, Margaret started to analyze her underwear, trying to see if there was anything odd with it, but not finding anything. As she did, she rubbed her sensitive areas, which she was surprised to find felt a little more sensitive than usual.

With deep blush on her face, Margaret momentarily considered masturbating right there, in the teacher's bathroom. The adventurous nature of such an idea went against her usual demeanor, but it strangely excited her, and the idea slowly took hold. Margaret decided it was down to how her underwear had been feeling today, but it left her with the growing idea.
