I've been writing this for a while and was going to wait until I had finished posting Midnight Shadows but decided why wait lol. It's a lot different to the other stuff I've written for Twilight but I wanted to try something different. Please let me know what you think.

Author's Note: This story is rated M for strong adult themes, especially sexual, and language. I've tried to write it so if you don't want to read the stronger sex scenes you can miss those chapters without missing any of the storyline. I will put a warning before each chapter that has any sex scenes in it. Bella is not in this story and is not likely to appear. I am sorry if Bella fans are reading this but I'm not real fussed on the character and find her hard to write so I've introduced a fictional character of my own to even the numbers up (A twin for Rosalie named Larissa). Also this will not be a traditional Jalice story so if you are reading this is the hope that Jasper and Alice will fall in love, it won't happen. Still they are my favourite characters so it will be more Jasper and Alice focused than any others. I wanted to experiment with them in a different kind of relationship and with other characters, you'll see what I mean later on, don't want to give too much away. Also, Edward fans may not like this story later on, just so your warned. All characters are human. Anyway, I think I've rambled enough so I hope you enjoy this.

Disclaimer: I got the idea for this story while reading The Teenage Angst Brigade by jandco at A Different Forest. I should also give credit to JazzyLittleMonster for their story The Alice Brandon Recovery Program which is based on The Teenage Angst Brigade and posted here and was what pointed me to that story in the first place. This isn't a re-write or an outtake story on these stories, I just got the basic idea while reading them and because there may be some similarities I wanted to give credit to save hassles later if these authors read this. All ideas are mine except the basic pact idea which I give credit to jandco for the original idea although in this it differs to the one in The Teenage Angst Brigade. Also I don't own any of the characters you recognise from Twilight, they obviously belong to Stephenie Meyer.

Chapter One- An Idea Begins to Form

Jasper Whitlock cracked one eye open and groaned when he saw the morning light coming through the window. He groaned as he stretched and his morning wood strained against the confines of his boxer shorts. He glanced at the clock and realised he only had an hour until he had to be at school and he reluctantly threw back the covers and crawled from the bed.

He walked into the bathroom that adjoined his bedroom and switched on the taps of the shower before walking over to the toilet. He dropped his boxers and wrapped his hand around his erect penis as he strained to pee. When he was finished he reached over and flushed the toilet and then stepped under the hot streaming water. As the water flowed over him and woke him up properly he reached down and wrapped his hand around his erection. He began to tug back and forwards on it as he reached his other hand to lean on the tiles of the shower.

He knew he was a long way from coming and although he always felt guilty afterwards he knew from experience the only way to get himself off was to think of the Hale twins, or more specifically Larissa Hale. He squeezed his eyes shut and imagined what she would look like naked and writhing underneath him as he jammed his erection into her hot juices and his hand quickened.

"Oh God!" Jasper groaned as his hips pushed forward and his hot cum shot towards the wall of the shower. When he was finished he took gasping breaths as he rested with both his hands on the tiles and his head slightly hung, as usual feeling dirty and guilty after jerking off over Larissa. Alice was like a sister to him and Larissa was her best friend and she was also one of their gang. He knew they would all be disgusted if they knew what he was imagining as he stroked himself but he couldn't help it.

"Hey Jazz!" a voice called out from the bedroom and Jasper groaned, his body still trembling from his orgasm. He knew it was Alice and he also knew she was that comfortable with him she was likely to just barge into the bathroom.

"In the shower, be out in a minute," Jasper called out, his voice hitching slightly from his exertions. He grabbed a sponge and quickly washed himself before making sure his cum was rinsed from the shower and then he stepped out and grabbed a towel. He wrapped the towel around his waist as he walked back into the bedroom and he smiled when he saw Alice sitting in the middle of his bed cross legged and flicking through a girly magazine out of his drawer.

"Why are you reading that?" he asked with a laugh as he walked over to his dresser and pulled jeans, boxers and a shirt from it.

"It's the only thing I could find," Alice shrugged and turned the book around and held up a two page spread of a naked woman. "What is the appeal, really? She's got big floppy tits."

"Alice!" Jasper gasped as he pulled on his boxers and then dropped the towel.

"Well, it's true," Alice sighed as she threw the magazine aside. "Have you had breakfast? We only have ten minutes till we have to pick up the twins."

"Nah, I've only just woken up," Jasper shook his head as he pulled on his jeans.

"You get ready and I'll make you some toast," Alice grinned and jumped from the bed and raced from the room. Jasper laughed at her early morning exuberance and hurried to finish getting dressed. When he was done he grabbed his books and shoved them into his satchel and then he ran down the stairs to the kitchen. Alice was just buttering his toast for him and she had also grabbed a bottle of juice from the fridge.

"We've got to go, we'll be late," she said as she handed him the food and then grabbed her bag from near the door. Jasper nodded and snatched his keys and followed her outside to his car.

He unlocked the car and they both climbed in and Jasper drove towards the Hale house as he munched on the toast and Alice fiddled with the stereo. He glanced at Alice and smiled as he thought about their friendship. Alice and her family had moved into the house next door to Jasper's when they were only babies. They had become play mates and Alice's mother had become Jasper's babysitter when his mother had returned to work when he was two. He had grown up with Alice and she was like a sibling to him, as was her younger brother Alex.

She had been best friends with Larissa Hale since preschool and when Jasper had got his first car at the beginning of the school year Alice had begged and pleaded until Jasper had agreed to pick up the Hale twins on their way to school every morning. He pulled up outside their house and honked the horn and seconds later the door flung open and Rosalie and Larissa ran out. Although they were twins they weren't identical and Jasper was glad of that.

Rosalie was more stunning according to all the other boys at school but Jasper didn't see it. He admitted she was hot but she had a vicious streak and she knew she was good looking and had the attitude to match. Today she was wearing tight jeans and a skimpy top and her full breasts strained at the material. Jasper was use to it now though and he barely gave her a second glance. Instead his eyes lingered on Larissa and he was glad he had sunglasses on so Alice didn't see him checking out her best friend.

Larissa had the same long blonde hair as Rosalie but her features were more delicate and her curves softer. Today she was wearing jeans too, but they didn't cling like Rosalie's did and her top was pretty and feminine but concealed the things Jasper dreamed of. Even just looking at her skipping towards his car made his pants tighten and he wriggled and looked away from her as he struggled to control his reaction to her.

"Hi guys," Rosalie said as she approached the car.

"Hey Allie, Hey Jazz," Larissa grinned as they both jumped into the back seat of the car.

"Hi Rissa," Alice smiled. "Hi Rose."

Jasper pulled out and drove towards the school as the girls chatted lightly about clothes and boys and all the things teenage girls talked about and when they reached the school Jasper parked the car quickly. They all climbed out and Jasper mumbled a quick goodbye to the girls and hurried off into the school.

At lunchtime Jasper walked into the cafeteria and grabbed his lunch before heading towards his usual table. Rosalie was already sitting there along with the other two members of their group, Emmett McCarty and Edward Masen. The two other guys had been friends since birth, their mothers had grown up together and raised their children together. Emmett had five brothers, two younger and three older but Edward was an only child. Even though they were best friends they never made Jasper feel like an outsider and he knew he could just turn up at either of their places any time.

He sat down at the table and began to eat his lunch as he listened to Emmett and Edward argue over who had to highest score on Emmett's X-box. Jasper glanced to the door of the cafeteria and smiled when he saw Larissa and Alice walk in, their arms linked as they chatted conspiratorially about something. They grabbed their own lunch and then came over and sat down with the group and Alice giggled as she looked around them all.

"Do you all remember what today is?" she smirked.

"No, what?" Emmett frowned.

"We have sex ed in biology this afternoon," Alice giggled.

"Oh fantastic," Edward groaned. "If they make us put condoms on bananas again I am going to chuck."

"Maybe you should use a pencil instead," Emmett teased. "For better accuracy?"

"Screw you Emmett," Edward snapped as the girls dissolved into giggles.

"Hey Jazz, are we on for tomorrow night still?" Larissa asked and Jasper glanced at her and realised she was changing the subject to cover Edward's embarrassment.

"Yeah," Jasper nodded as he realised it was Friday which meant she was asking about their usual Saturday night sleep over. Most weekends his mother was away on business trips, well most weeks too actually, but they had got into the habit of hanging out at his house. They normally grabbed take out and watched movies and just clowned around but they all loved the weekends.

"Aren't we going into Seattle tomorrow?" Emmett frowned. "We have those tickets for the basketball game."

"That's the afternoon though," Jasper shrugged. "We'll be back by dark. You girls can just come over when you want, Alice knows where the spare key is."

"Cool," Rosalie grinned.

"We should hang out by the pool for the afternoon," Alice suggested.

"Go for it," Jasper shrugged.

The bell rang and with their weekend plans cemented the group got up and left the room together and headed for their biology class. The sex education talk was nearly as bad as they expected. Although they didn't have to do anything with condoms and bananas that year the teacher insisted on talking about the threat of STD's and unprotected sex. It made them all uncomfortable and the whole class was pretty much squirming when the class finally finished. Jasper was one of the first to jump up and race from the room and he hurried to History class as he tried to put the topics out of his mind.

Jasper bounced in the back seat of Emmett's jeep and was relieved when they turned into his street. Emmett's driving was atrocious and he wondered why he and Edward had agreed to let him do the driving to Seattle. They had all enjoyed the basketball game though and as Emmett pulled up at the house Jasper could see the lights on and knew the girls were already there.

The guys got out of the car and as Edward ribbed Emmett about his driving they walked in the front door. The girls were sitting in the living room as they chatted and Alice grinned when she saw the guys walk into the room.

"What's the topic?" Emmett asked as he flopped down on the couch beside Rosalie who squeaked as she bounced.

"We were talking about biology yesterday actually," Alice admitted as Jasper sat down beside her and casually threw his arm around her shoulders.

"Wasn't that just freaky," Edward groaned.

"Tell me about it," Larissa whispered quietly.

"It was nearly enough to put me off sex," Emmett admitted.

"Like you get it anyway," Edward teased him and they all burst out laughing.

"Except from himself of course," Jasper added and the laughing got harder.

"Very funny," Emmett growled.

"So what movie are we watching tonight?" Alice asked as their laughter died down.

"It was Rosalie's turn to pick," Jasper shrugged and they all turned to Rosalie.

"I brought a few," Rosalie smiled and reached into her bag and pulled out a pile of dvds. "But this is the best I think."

She held up a case and waved it and they all saw the name of the movie was The Pact.

"Oh I heard about that one," Alice grinned.

"Me too, I've been wanting to see it," Larissa added.

"I know, that's why I got it," Rosalie giggled and Larissa and her shared a private look, the same one that often confused the rest of them. Even after years of hanging out with them the bond between the twins sometimes threw them all.

"What's it about?" Emmett asked.

"A group of teenagers," Rosalie told him. "They make some sort of pact where they only have sex with each other. It's a comedy and apparently it's hilarious."

"Well, chuck it on then," Jasper shrugged and they all settled back as Edward got up and dimmed the lights and Rosalie started the movie.
