A/N: I'm back with another Austin & Ally story. This one is going to be much longer multi-chaptered one and don't worry there will be plenty of UST and fluff in later chapters! So if you don't know already I'm from the UK so the only things I get about America and the education system and all that jazz is from the internet, so feel free to correct me if I'm wrong! Also in this, Ally's mother died when she was about two, so she's only mentioned a few times. Thank you and please enjoy the first chapter of Summer Boom.

Chapter 1

Ally Dawson sat impatiently at her desk, tapping her newly painted fingernails along the wooden desk, wishing the minutes would tick by faster. Only one more hour of school left and she'd be free for the summer, along with her best friend Trish and she could barely contain her excitement. She tried to focus on what Mr Dutton, her chemistry teacher was blabbering on about but she was so lost in thought that there was no point in trying. Glancing around the room, Ally noticed that none of her peers were even making any attempt to focus on what the grey-haired man was talking animatedly about so she decided that day dreaming about her summer plans wouldn't get her in much trouble, since she wasn't the only one doing it. Letting her mind drift off, Ally remembered how excited she was last year as her dad slung all their suitcases in the back of the taxi and they headed for the airport, she was bouncing up and down in her seat, blabbing on to her father about all the fun things they were going to do that summer and how she'd missed being down there and how she couldn't wait to lie on the beach, her father had to wrap his arms around her bouncing frame and remind her that she was fifteen years old before she even thought about calming down, she always got too excited.

The one thing Ally loved most about going to Miami for the summer wasn't the glorious weather, each and every day until she'd leave would be scorching, her father would always warn her to lather herself in sunscreen to avoid burning up as she lay out on the beach and it wasn't the fact she got to work in her father's music store, Sonic Boom, where she was surrounded by instruments and music, two things that she loved more than anything in the world, no, it was the fact that she got to spend the whole summer with her best friend, Austin Moon. They met when Ally's father first opened the shop, he had his first store up in New York and it had been a success with the younger generations, they made thousands each day and Lester decided to open another store in a warmer climate where he could spend his summers with his little girl. So whilst his deputy manager ran the store up in New York, Lester and Ally travelled down to Miami where he bought an empty lot place in the Mall of Miami and built what became the well-loved by everyone that entered, Sonic Boom. The first summer it opened, Lester had been nervous, not only did he have a five year old daughter running riot around the store but he didn't have his wife by his side like he had when he opened his first store. Ally's mother, Jessica, died when she was only young so Ally could barely remember her but Lester could always see sparks of her in their little girl.

As he opened the doors at eight am and let the warm Miami breeze flow into the store he was surprised to find a small queue of people waiting outside the doors, eager to take a peak of the new store. Sending Ally upstairs into his office, which would later become her practise room, he quickly served all his new customers, welcoming them, thanking them and helping them with all their purchases and any items they were looking for. He was a big hit. As the days started to roll by, he let Ally roam around the store, letting her become accustomed to the environment he hoped she'd work in when she grew up. Ally was a lot like her mother in the sense she knew when was time to play and when was the time to work and she could sense by the serious look on her father's face as he helped a young man pick out the perfect guitar, that it was time to work. So little Ally trotted around the store, making sure everything was in order for her father, she wanted to help him as much as she could.

So when a loud racket came blasting from the drum set, she immediately ran over as fast as her little legs would carry her and stood before it, her arms crossed and a stern look on her cute little face.

"Wa' are you doin'? You're not allowed to do that!" Ally spoke loud and firm, watching as a little blonde boy around the same age as her stopped what he was doing and swivelled around to face her.

"Oh, it's okay, my daddy taught me to drum and I'm awesome at it." He grinned at her before taking a bite out of a corn dog in his hand.

"And I'm his filmer, I'm making his videos for when he's famous." Another boy peaked out behind the drum kit, his fluffy red hair widely sticking up in places as if he had just rolled out of his bed.

"Well my daddy made signs, look," Ally pointed to the sign about the drum kit and then proceeded to point to the signs above all the other instruments, "They say 'please do not play' so you are not allowed." She stormed off, ready to tell her dad about the little rebels before she received a tap on the shoulder, she turned around to see the blonde boy standing behind her, his hands in his pockets and his little red haired friend standing just behind him.

"I'm sorry, I didn't mean to make you angry, I just wanted to play." He stuck his bottom lip out and Ally giggled at his cute little face.

"It's okay; I'm Ally by the way, my daddy bought this shop." She smiled at him before shoving her hand towards him, how she saw her father do to all the men in suits he had met just before they opened the store.

The little boy grabbed her hand and shook it aggressively, giggling in the process, "I'm Austin and that's Dez." He pointed to his ginger friend, "Do you wanna come and play with us?"

"I can't, I have to help my daddy but you can come and help too if you want?" Austin grinned and nodded his head at her, grabbing her hand and pulling her over to the wall which proudly held the guitars.

"We can protect these from bad guys trying to get them from your daddy." He folded his arms and pouted, pretending he was a bodyguard like in those action movies his dad let him watch when his mother wasn't looking. Ally smiled widely at the little blonde boy before copying his pose.

Ally remembered they stood like that for hours before her father told her they could go play in his office with her toys as long as they didn't touch anything that wasn't theirs. And so that was the beginning of the friendship between her and Austin. And Dez of course. Each year when they travelled down to open the store for summer, she'd split her time between working for her father and hanging out with Austin, although whenever she was in the store, Austin and Dez seemed to appear and then never disappear until it was time to shut but she didn't mind, she loved their company. She was surprised that as they all grew older each year, they would find more and more things that they had in common, like their shared passion for music, each with their own idea on what they wanted to do to break into the business, Ally wanted to write songs, Austin wanted to sing and Dez wanted to direct music videos and eventually films. Ally enjoyed her time alone with Austin the most because then they could write songs together, sharing their passion for music and singing their final creations, spending hours and hours in her practise room until her father would shout them down for dinner.

The ringing of the final bell pulled Ally from her trip down memory lane and she grabbed her things and raced out of the room, she'd promised to meet Trish at her locker at the end of the day so they could go off to her house and pack, ready for the trip down to Miami tomorrow. Squeezing through the crowd of excited teenagers, all eager to rush out of school, she finally reached Trish who was stood with her arms wide open and a huge grin on her face, one that mirrored Ally's as they raced to each other, hugging and bouncing up and down.

"Miami, Miami, Miami!" They both shouted in unison, attracting stares off random passers-by before they collapsed in laughter.

"I can't believe it, we're going tomorrow! It's going to be the best summer ever!" Trish exclaimed, pulling Ally along with her as she raced out of the halls, heading towards the car park where her mother had promised them a ride home.

"I know it's going to be awesome! Spending the summer with my best friend in the city that I love! What more could a girl ask for!" Ally giggled as they climbed into Trish's mom's car, saying their quick 'hello's before they began chatting away about their plans for the summer.

"You just can't wait to see Austin!" Trish nudged Ally and she giggled before blushing.

"He's my best friend, of course I can't!" Trish raised her eyebrows but Ally shook it off, he was her best friend and that was all that was too it. At that exact moment, Ally's phone vibrated and she pulled it out of her bag, smiling when she saw who the message was off, Austin; it was like he could hear what they were talking about.

Message from Austin M.

School's out! You'll be here tomorrow, can't wait! Missed you.

-A

She quickly typed out a reply before turning back to Trish and engaging in another animated conversation about what Trish was going to bring for the next few weeks.

Austin Moon literally ran out of the classroom as soon as the last bell had rang, he bumped into several people who were rushing out but he didn't really care, he couldn't wait to be out of the prison he had to call school and onto the summer, spending it with his two best friends. He smiled instantly as he thought of Ally and pulled his phone out of his pocket to see if she had replied to him yet, he grinned as he saw the flashing which indicated he had a new message.

(1) New message from Allygator D.

I'm sooo excited! Trish is too, she won't stop talking! Our flight lands at 8 am so I'll see you in the afternoon. Missed you too.

-A xox

Austin was staring down at his phone, a wide grin on his face he didn't even notice he was walking straight into someone until they collided, books and bags flying around and a girlish squeal escaped which Austin begged was not him. Looking at the person he had just bumped into, his eyes went wide when he realised who it was.

"Cassidy! Oh, I'm so sorry, I wasn't looking… I didn't see… I'm so sorry!" He spat the words out and he helped the girl up, pulling her bag off the floor and helping her place the books back in. His heart sped up as she flashed a smile at her, her pearly white teeth gleaming at him.

"It's fine Austin, it's the end of school, no-one's ever paying attention!" She giggled at him, before bending down and picking up his dropped cell phone, "Here you dropped this." She quickly gazed at the phone, not caring if it was being nosey or not. Her heart sank a touch when she saw that it was off a girl, it wasn't that she was jealous because she didn't like Austin, she wasn't saying he was ugly because he was probably one of the best looking boys in the school, it was just she was a year older than him and whilst she enjoyed the little crush he blatantly had on her, she was looking for an older, more mature boy to steal her heart but she didn't enjoy the fact that another girl was stealing Austin's heart. Tossing the phone to him, she muttered a goodbye and strutted off down the hall, towards the cluster of girls she normally hung around with.

Austin watched after her, his heart fluttering slightly before an arm was slung around his back, dragging his attention away from the girl he pined for. He turned to see Dez, staring at him, a goofy grin across his face.

"Austin baby! Summer is here." He whistled as they made their way towards the school doors, "As soon as your girlfriend gets here, the fun can start!"

"She's not my girlfriend!" Austin shot back, pulling his backpack closer against him and waltzing out the school gates, Dez slowly trailing after him. He hated whenever Dez called Ally his girlfriend, she was his best friend. Sure, she had become a lot hotter the past few years as she grew up from a little girl who loved playing with his fire truck into a young girl who shared his dream of becoming a star but they were just friends, besides he was trying to get Cassidy to notice that he was grown up now and not the same old little boy who used to glue his hands together to try and impress her.

"Sorry man but anyway, let's get going! We can start planning all the fun we can have, we can go the zoo and see the kangaroos, you know I love kangaroo's man and then we can steal them and ride them on the beach and, oh I hope Ally's friend is hot, I mean, I don't wanna have another lonely summer with you." Dez blabbered on as Austin watched him, smirking as his friend made up crazy idea's that he knew they would never be able to accomplish would spending some time in a real prison.

"Dez, I don't even think they have kangaroo's at the zoo but we'll find you one okay? And I don't know if she's hot but were still going to have fun right?" Dez nodded at him, a little let down that his friend had put a damper on his dreams but he soon smiled as he heard the familiar jingle of the ice cream truck, roaring down the street opposite them.

Austin laughed as he watched his best friend zoom off after the ice cream truck, the way he used too when they were five. He sighed as the sun hit his face; he knew that this was going to be a summer he'd never forget.
