Sarah looked at herself in the full length mirror. She would never normally have worn such a short dress to work and she certainly wouldn't ever have worn the underwear that she had chosen for today. Today was the end of the school year, however. She had somehow managed to complete her first year as a qualified teacher and she told herself she had every right to celebrate.
She was the youngest teacher in the school by far and, even though she was totally oblivious to the fact, she was the one who turned the heads of most of the other teachers, male and female. Being only a few years older than some of her students, she had exactly the same effect on some of them. Again, it wasn't just the eighteen year old boys who wanted to get to know her better; some of the more precocious girls did too and, again, Sarah was totally unaware of all of this.
She still had the final morning's classes to get through before the students departed for the summer and the staff all made their way to the Headmaster's home for the first barbecue of the season. That was why she had chosen her new summer dress; she knew she didn't have time to come home to change after school but she was very aware of how short her dress was, barely reaching half way down her smooth thighs. She was even more acutely aware of how skimpy her underwear was but she wanted to feel good about herself today. She was still intimidated by the older teachers and she knew that, if she could feel sexy underneath her dress then, maybe, it would give her more confidence at the barbecue.
Smiling to herself once more in the mirror, she picked up her keys and bag and made her way out the door. It was already hot, even at this time in the morning and she was glad she had convinced herself not to wear her usual school attire. She felt the warm breeze on her face and luxuriated in the thought of a long, hot summer.
The drive to school was short and she really didn't need to bring the car. She would need it later, however, to get to the Headmaster's house and then to get home later on. Reaching the school, she pulled in to her usual parking space and got out of the car. Just when she was about to press the button to close the central locks, she remembered she had left some books on the passenger seat and, without thinking, opened the door and reached across to pick them up.
Almost as soon as she leaned forward she realised she had made a mistake. She felt her short dress rising up the back of her thighs and exposing her slender legs. At the same time the breeze that had caressed her face as she left home suddenly reappeared and flipped the thin cotton of her dress up, exposing her firm bottom cheeks. Even worse, she knew, was that she had chosen to wear a tiny white thong and the thin strap at the back had nestled between her cheeks during her drive. If anyone had been standing behind her they would have thought she was naked from the waist down.
Pushing her dress down with one hand, she grabbed her books with the other before straightening up and locking the door once more. Her face was blushing at the thought of the inadvertent exposure but she was horrified when she turned round to see Tommy Wilson standing there. Her face burned a deeper shade of red as he grinned at her and, even though Tommy never uttered a word before sauntering away, Sarah knew he had had a good, if fleeting, look at her seemingly bare bottom.
Tommy Wilson was the last person she would have expected to see standing behind her. He was in his final day at school and should not have been anywhere near the staff car park. It didn't help that Tommy was one of the most physically attractive boys in the school. He was no boy; he was a fully grown man, much taller and obviously much stronger than his teacher. But he had a bad reputation and the school would be just as relieved to see the back of Tommy Wilson as he would be glad to see the back of it.
The rest of the morning passed uneventfully, although Sarah became increasingly aware that her thong was riding higher and higher between her cheeks and, in turn, her pussy was becoming wetter and wetter as the tiny piece of cotton clung to her moist lips. Now the last class was about to begin; the last class of the morning; the last class of the school term. Tommy Wilson's class.
All the students were in high spirits and Sarah didn't have any great urge to get them to quieten down. She just wanted this last hour to pass so that she could feel as if she had really accomplished something by completing her first year as a teacher. Some of the boys were becoming more and more boisterous, however, and she felt as if she should step in before they overstepped the mark. That was her big mistake.
As she walked over to where they were gathered in a group, she asked them to keep the noise down. They separated and she saw that Tommy was in the centre of the group, showing them a photo he had taken on his phone. Trying to keep the atmosphere friendly, she said,
"Can I take a look too?"
Tommy grinned the insolent grin that only an eighteen year old boy can and handed her his phone. She was shocked; shocked at how clear the photo was and shocked by the fact that she was looking at own seemingly naked bottom sticking out of her car. Her face became bright red and she instinctively became the teacher again, raging against the boys sitting before her and deleting the photo from the phone. As she handed it back to Tommy, he saw what she had done and now it was his turn to be angry.
Jumping to his feet, he began to shout and swear at her. Towering over her, she became quite frightened of his rage filled face and she cowered from his power, just a little. A little was enough for Tommy. Seeing his chance to finally get his revenge on this school he turned to his friends.
"Grab her."
Without a moment's hesitation, they did as they were told. Tommy was their leader and they would love to see more of this sexy young teacher whose arse Tommy had photographed this morning.
Sarah struggled against them but she was no match for these football playing boys and very quickly found herself being thrown across her own desk. Her long hair was blinding her as she threw her head from side to side, screaming at them to release her.
"Someone shut the bitch up," she heard Tommy yell and a meaty hand was placed firmly across her mouth, reducing her screams to whimpers. Her eyes were also covered by a smelly piece of cloth and she could no longer see who taking part in this assault. Starting to feel quite frightened by the turn of events, she tried to get up but her arms were grabbed and tied to two legs of her desk. With only her legs now free, she tried to kick out at her unseen assailants but they too were quickly secured and now she was really scared, lying there spread-eagled on her own desk, at the mercy of her students.
As the hand was removed from her mouth she tried to talk herself out of her predicament and began to reason with her chief tormentor.
"Ok, Tommy, you've had your fun. Let me go now and we'll say no more about it."
"I haven't even started to have fun yet, miss. You owe me a photo."
"What do you mean?" she asked, terrified, knowing exactly what he meant but not wanting to think about it. She could feel her short dress lying high up her smooth thighs and she knew it wouldn't take much for any of the students to lift it up and expose her tiny knickers to the whole class. He face burned red in embarrassment and it got even redder when she felt someone, presumably Tommy, lean across her body and begin to open the buttons at the top of the summer dress.
"No, please; don't do that. Please! Let me go!"
"If you don't shut up, miss, then we will shut you up and, I promise you, you won't like that."
Not sure if she was more frightened or humiliated now, Sarah held her tongue and squirmed in embarrassment as she felt the buttons over her small breasts open, exposing her even smaller bra to the eyes of her class.
"Wow, look at those gorgeous tits. I've got to get a photo of them."
Sarah recognised the voice as that of one of the quieter girls in the class. Surely that couldn't be Maria, a girl you wouldn't even know was there unless you had marked her as present in the register. Sarah heard a lot of commotion round the desk as she lay there, prone, at their mercy. Listening to them, she realised from their comments that they had all opened their phones and were taking photos of her small breasts; those same breasts that were covered only by the tiniest bra she had ever bought. It was part of a matching set, along with her tiny knickers, and they both made her feel very sexy whenever she wore them. Now they made her feel terribly exposed and she rued the day she had ever bought them, never mind deciding to wear them to school today.
As she felt more buttons on the front of her dress being opened, she shook her head until the hand over her mouth released her and she begged for mercy once more.
"Please, Tommy. You must stop now. I can still forget any of this happened but you must stop now. And you must delete all those photos."
"I warned you, miss; don't say you weren't warned. Diane, have you got something to gag her with." Dianne wasn't a quiet girl. Dianne was the biggest slut in the school and Sarah had always been intimidated by her, even if she was the teacher and Diane was the student.
"I've got just the thing," she heard Diane say and then wondered what was going on as she heard a burst of nervous giggling from the other girls. There was no way she could know that Diane had pulled up her short skirt and was removing her own knickers, the same knickers that had been catching Tommy's cum as it poured out of her cunt since he had fucked her before school this morning.
Someone pinched Sarah's nose and she was forced to open her mouth to breathe. As she did so, Diane stuffed her dirty knickers into the young teacher's mouth, making sure that the stained crotch was pressed against her tongue, making sure that Sarah could taste the mixture of Tommy's and her own cum. Sarah gagged at the taste, not sure what it was and not really wanting to think too much about it. Diane wasn't a small girl and her big knickers filled the young woman's mouth as she was silenced once and for all.
