Chapter 1: Her Big Mistake
Starting a new school is never easy, having to do so when you're 18 is even more tough as you really feel like an outsider in a class where most of the other students have grown up together. Caroline had been raised by her aunt who had fallen out with her previous landlord, with the market what it was she couldn't find anywhere reasonably priced close to Caroline's old school, so early in her senior year she found herself starting at a girls school in London near to her aunt's new apartment. Caroline was only 5 foot 2, she had small breasts & shoulder length mousey blonde hair, her face, legs & ass were all okay looking but nothing about her grabbed the attention.
Usually Caroline cycled to school, due to cycle lanes & pedestrianised zones she could actually get home faster than if she caught the bus, but as classes finished on her third Monday at her new school the heavens opened. There was a bus stop almost directly outside the school gates so she sprinted to the bus shelter. By the time the first bus going in the right direction arrived there were a lot of girls waiting for it so seeing her classmates rapidly filling the lower deck she lugged her bike up the stairs & went to sit on the long back seat of the completely empty top deck.
When a few seconds had gone by & still nobody else came upstairs Caroline started to wonder if the top deck was supposed to be closed or something, as it sounded like the lower deck was absolutely packed, but then a group of seven girls appeared at the top of the steps. Caroline recognised them, they were sort of a gang. Kelly, Marissa, Alissa & Taylor were all good looking, but their opinion that they were the hottest girls in school wasn't widely shared as they were a bit trashy. Kelly & Alissa were natural blondes whilst Marissa & Taylor coloured their hair to match their friends, they were all slim, all between 5 foot 5 & 5 foot 7 tall, all had nice breasts & all dressed quite slutty. Then there were Kim & Leanne, they were both tall & sporty, Kim had black hair & Leanne blonde, from what Caroline had heard they were allowed to hang around with the others as sort of their bodyguards. Lastly there was 5foot 4 black haired Fiona, Caroline had no idea why she was part of their group, she was only average looking, she wasn't strong or particularly clever & she wasn't even slightly cool, she was one of those girls who just tried too hard, Caroline had even heard a few girls laughingly refer to her as fishy Fiona.
As the gang came up the steps they were chatting with each other, but when Kelly caught sight of Caroline she stopped & said something quietly to the others before proceeding with just the three hot girls & Fiona, as Kim & Leanne had taken the seats right by the top of the steps.
The five girls stopped & stood in the row in front of Caroline just as the bus started to move. Kelly was staring at Caroline in a way that made the seated girl think that a certain reaction was expected of her, but not knowing what it was she just sat there waiting for someone to explain.
"What are you doing up here?" Kelly had put a lot of emphasis on what,
"Everyone knows the top deck is ours," She added.
"We should punish her Kell," Alissa suggested eagerly,
"Your new at our school aren't you?" Marissa asked,
"Yeah, this is only my third week," Caroline answered sounding a little nervous.
"Three weeks is plenty of time to have learned the school rules & one of those rules is that nobody other than us uses this deck. Lissa's right, we should show her what happens when you break the rules," Taylor told her friends.
"Oh yes, let's!" Fiona agreed very enthusiastically.
Kelly stood there silently smiling down at Caroline, whilst Marissa had her phone out, the other three were waiting eagerly to see what their leader decided. Marissa showed Kelly something on her phone which made Kelly laugh before she finally spoke to Caroline.
"It turns out we're going to be here for a while, there's been an accident a few streets away & the traffic isn't moving, we aren't going to be disturbed either as Kim & Leanne are on guard. So we've got at least half an hour to show you exactly what happens to stupid new girls who invade our territory," The way Kelly was smirking as she said that scared Caroline just as much as what she actually said.
Kelly made a signal with her hand & suddenly Alissa & Taylor dived at Caroline, after a very uneven struggle Caroline was lying flat on her back on the long back seat of the bus, Alissa was sat on her legs & her arms were pressed hard to her sides, she had been handcuffed by Taylor & with the chain of the cuffs under her back it meant her arms couldn't move.
As Taylor climbed off of Caroline she grinned down nastily at her & gloated,
"You aren't the first girl we've had to teach a lesson for disrespecting us, handcuffs make it so much easier."
As Kelly stepped towards her Caroline saw that Fiona, Marissa & Taylor were all now sat on the row of seats in front of her but they were all kneeling & watching her over the back of their seats, Alissa was still sat on her legs.
"Here's the deal bitch," Kelly sneered as she moved to stand right next to Caroline's chest,
"We are the coolest girls in school & we're the hottest girls in school & I am the hottest of all," Her voice made it clear that in her mind those facts were undisputable,
"So new girls are supposed to kiss my arse, not disrespect me," She continued.
Kelly hitched up her skirt & before Caroline could say anything she stepped onto the seat & lowered herself to squat over the trapped girl. She had taken off her panties whilst her friends were pinning down Caroline & now she shoved her bare ass right in the prone girl's face.
"So this is the start of your lesson, pucker up & kiss my arse or I'll have Kim & Leanne come over here & give you some not so gentle persuasion, the last girl who needed to be persuaded of something by them still has her arm in plaster so kissing my gorgeous butt is definitely the less painful option," She added venomously.
Caroline thought for a couple of seconds, she was totally pinned down, she was out numbered seven to one, there was so much noise coming from the lower deck of the bus that nobody was going to hear if she shouted for help & as there was a girl in one of her classes who did have her arm in plaster she completely believed Kelly's threats.
Caroline realised that she had no choice & having another girl's ass in her face wasn't something she wanted, so she started planting kiss after kiss all over Kelly's cheeks in the hope that if she did what she wanted then the mean girl would leave her alone.
Kelly giggled as she felt Caroline's lips on her ass for the first time & as frantic kisses followed she laughed before saying,
"That's better, you know this is how it's supposed to be don't you? A plain insignificant girl like you is made to kiss the asses of hot girls like us, oh yes, keep going."
After a couple of minutes of literally having her ass kissed Kelly slid back without warning, now Caroline's nose was pressed up against her asshole & Kelly's pussy was over the trapped girl's mouth. Kelly laughed again as she felt Caroline squirm below her,
