This was going to be a one shot, but then I got inspired to make this a multi chapter story. Special thanks to MrsFerb Fletcher-inator! XD

I don't own P&F...

Sixteen-year-old Phineas came running into the house and darted up the stairs to the bedroom. Once he reached it, he shut the door and turned to look at his seventeen-year-old brother Ferb, who's currently on his computer. Ferb shoots him a glance before going back to his game.

Phineas smiled wide, "Who's your favorite brother?"

Ferb looked over his shoulder, "Excuse me?"

"I said, who's your favorite brother?"

Ferb thought for a moment, "Um... Phin you're my only brother..."

"Yeah, but I need to hear you say that I'm you're favorite."

"Okay... you're my favorite brother?"

Phineas placed his hand on Ferb's shoulder, "I'm glad you said that, because I just scored us two front row tickets to the Rock Stealer concert!"

Ferb paused his game and turned to face his brother, "You did what now? Phin that concert has been sold out for weeks? How on earth did you get them?"

Phineas grinned and started waving the two tickets around in his hand, "I have my ways... plus Buford was a big help."

Ferb snatched one of the tickets and looked it over. His brother spoke truth; these tickets were front and center for the Rock Stealer concert.

Ferb suddenly frowned, "Phineas these are great... but you know that the date of the concert is this Thursday..."

Phineas looked it over, "Yeah I know... so?"

"It's a school night, there's no way mum and dad will let us go to a concert on a school night."

"Well maybe they'll let us go since we have tickets already."

Ferb shook his head. Their parents put their foot down when it came to their education.

Phineas suddenly grinned, "We could... sneak out you know?"

Ferb's eyes grew wide. Was his brother suggesting that they lie and deceive their parents in order to go see this concert?

Phineas chuckled, "Come on, bro this may be the only time we'll ever be able to see them up close a personal. I can guarantee that I won't be able to get tickets like these ever again. And there's no one else that I would really like to go with."

Ferb looked back at his ticket, up to his brother then back to the ticket. He opened his mouth to say something, but nothing came out.

Phineas put his hand on Ferb's shoulder, "Please, Ferb… I promise we'll have a lot of fun and that we won't get caught. I have a foolproof plan."

Ferb raised an eyebrow at this. He's sure that they will have a good time, but the part about not getting caught… well he had his doubts about that. But being the softie he is, Ferb decided that he should go with his brother to make sure he stays out of trouble. Ferb sighed and nodded his head. Phineas smiled wide and hugged his brother,

"Yes, yes, yes! Thank you Ferb!"

Ferb groaned, he could already tell that he's going to regret this decision soon.

"Okay," Phineas spoke, "the concert is in two days. So we're going to have to be ready. You have your license so you're going to have to drive us there."

Ferb looked shocked, "Are you kidding me? We can't take the car, mum and dad will hear us."

"Not unless we roll it out into the street and start it off once we're a safe distance away."

Ferb looked even more shocked. Where was his brother getting all these sneaky ideas?

Phineas smiled and patted Ferb's arm, "Don't worry about anything, Ferb… I got it all planned out…"

Ferb groaned before turning back to his game on the computer. Something told him that he was soon going to regret this decision about sneaking out…

Boy was he right.

The couple of days before the concert were complete torture for Ferb. Everytime he looked at his ticket he felt excited, but then he would glance over at a picture of him and his dad looking as happy as could be. As soon as he saw that picture, he would get this knot in his chest. He had a very close bond with his dad. He has never hid anything from him, nor has he ever tried to lie to him. Keeping the secret about the concert was killing him from the inside out. Something was bound to go wrong in his brother's foolproof plan, right?

The night before the concert, he watched as Phineas smiled at their parents as they spoke and laughed together. Ferb could tell that Phineas was just trying to get on their mum and dad's good side in case things go wrong. Ferb sat back in his chair and watched his brother for a while, until he heard his dad say something. Ferb looked at him and noticed Lawrence was looking right at him.

"Sorry, I didn't catch that." Ferb spoke,

Lawrence frowned, "Are you alright, son? You look a little worried about something."

Ferb bit his lip and glanced over at Phineas, who gave him a worried look. Ferb looked back at his dad and smiled,

"I'm fine, dad…"

Linda raised an eyebrow, "Are you sure you're okay? You do look a little flushed."

Ferb gulped and just shook his head; "I'm fine mum… it's just a little warm in here…"

As the rest of the evening went on, Ferb started getting this sick twisted feeling in his stomach. He had excused himself early and went to bed early. After a few minutes, Phineas came upstairs and looked down at his brother,

"Ferb are you okay? You looked like you were going to be sick before."

Ferb moaned, "I'm having a hard time with this sneaking out thing… the lies, the deceit, all of this dishonesty…"

Phineas frowned, "Bro, you never really spoke today. I didn't hear you say a single lie to anyone. Heck, I didn't even have to lie."

Ferb sat up in bed, "I don't have to say a word in order to feel guilty, Phin… just knowing what we're going to do tomorrow night is… well, it's killing me."

"Do you want to back out? Because I totally understand if-"

Ferb shook his head, "Nuh uh…"

Phineas sighed and shrugged his shoulders, "Okay man, we should probably get some sleep then, we have an exciting night ahead of us tomorrow."

The next morning came around, and Ferb was feeling worse then ever. He couldn't help but look at his dad with a guilty look. Lawrence has done so much for him, and how is Ferb repaying him? By sneaking out of the house with his younger brother. Ferb started feeling sick to the stomach during school. Not the 'I'm going to throw up' sick, but the 'I feel so guilty it's killing me' sick.

School dragged on slowly that day and when the two boys arrived home, they dashed up to their room to get their homework done. The two boys sat on their own beds and worked in silence.

Ferb started biting his lip as he looked at all of the numbers on his worksheet. As he wrote down his answers, he felt something nudge his side. He glanced up and saw Perry looking up at him and chattering. Ferb gave Perry a small smile before turning back to his worksheet.

A small knock on the door surprised the boys. They looked up to see Lawrence walking in. He smiled at them and crossed his arms,

"Having fun with your homework boys?"

Phineas moaned, "Since when is homework ever fun?"

"I guess that's true. I just came up to tell you two that I'm going to take your mum out to a dinner and a show tonight, so you'll have the house all to yourselves for the night."

Phineas smiled, "Cool dad… hope you two have fun."

Lawrence nodded and gave them both a firm look, "I expect you two to not throw any parties or anything while we're gone though. Remember when your sister tried that on us?"

"Yeah dad we remember, and don't worry. We plan to have a nice relaxing evening at home tonight. Right Ferb?"

Ferb's pencil froze as he glanced up at his dad. Lawrence turned to Ferb and awaited his answer. Ferb shot him up a smile and nodded his head.

Lawrence smiled, "Alright boys, just make sure to get to sleep at a reasonable hour. It is a school night after all."

Phineas nodded his head, "Of course dad…"

Lawrence nodded as he backed out of the room, "Okay I'll let you two finish up then. We'll let you know when we're leaving."

After he left, Ferb picked up his pillow and flung it angrily at his brother. Phineas ducked and looked up surprised,

"Whoa Ferb… what's gotten into you?"

Ferb scrunched up his fists and turned back to his paper. He felt a twinge of hate towards his brother for making him lie to his own father, which is something Ferb promised himself years ago that he would never do.

"This is about is sneaking out tonight, isn't it?"

Ferb didn't reply. He kept his attention focused on his paper as he scribbled out all of his answers.

Phineas raised his arms in the air, "I repeat myself, if you don't want to go through with this, let me know and we can call it off. I'll… sell the tickets to someone else and-"

Ferb slammed his book closed and shook his head, "I said I'd go with you… and that's exactly what I'm going to do. Just please promise me that I won't have to lie anymore."

Phineas gave his brother a reassuring smile, "I promise… I'll do all the talking for you from here on out. Okay?"

Ferb nodded his head and turned back to his paper.

Phineas let out a sigh, "Well… looks like we're going to have to call a taxi or something since mom and dad are taking the car tonight. Hm… maybe Buford will let us borrow his car."

Ferb just nodded and stuck his finished paper back into his folder.

The rest of the afternoon and evening went pretty quietly. Around seven o'clock, Lawrence and Linda called their boys down to say goodbye. After giving each of them a hug, Linda smiled at both of them,

"Have a good evening boys. We'll probably be out past midnight so don't wait up for us."

Lawrence nodded and looked at Ferb, "Since you're the oldest, I'm putting you in charge of the house, okay?"

Ferb gulped and slowly nodded his head, "Yes sir…"

"Emergency numbers are in the fridge in case you need to get a hold of someone. Be good boys and we'll see you tomorrow."

Phineas nodded and waved, "Bye guys, have a good time tonight."

Both brothers watched as their parents hopped into the car and pull out of the driveway. After sitting quiet for a few minutes, Phineas pulled out his phone and placed a phone call. After exchanging a conversation, he hung up the phone and cast his brother a large smile,

"Buford is going to let us borrow his car, no charge. Isn't that great?"

Ferb nodded his head as he stood up. Phineas stood up as well and smiled wide,

"Guess we should get ready to go, huh?"

Ferb nodded again and followed his brother upstairs. After they changed and grabbed their wallets and tickets, they walked back downstairs. Once they locked the front door, the two of them began walking to Buford's house.

Once they reached his house, Buford handed Ferb they keys and gave him a warning,

"Get one scratch on my baby, and you'll get a nice shiner on your eye."

Ferb nodded and gave him a thumb up. In the past moths that Ferb has had his license, he has never gotten into an accident.

After saying goodbye, the two boys climbed into Buford's used car. It was broken down and ducked taped in some areas, but it still ran like a dream… well, according to Buford that is.

Ferb stuck the key into the ignition and started driving off. The stadium was about twenty minutes away so they had some time to kill.

Phineas did all of the talking on the way there. He talked about school, their friends, their parents and how he wonders if Isabella likes him like he likes her. Ferb rolled his eyes and mumbled under his breath,

"Some things never change…"

Ferb still felt uneasy about all of this. When promised himself that when they got home, he would come clean to somebody. Hopefully Perry won't mind hearing Ferb talk about this whole situation throughout the rest of the night.

Before they knew it, Ferb was pulling into the parking lot for the stadium. They didn't get a great parking place, but they still had some time before the concert started. Once they were inside, the two of them decided to order some snacks. Phineas ordered a large soda, two hot dogs and some candy. Ferb ordered a small soda, a cheeseburger and a bag of M+Ms.

Once they got their food, they began their walk towards the entrance that led to the stage. A man scanned their tickets and directed them towards the front. Phineas gave Ferb a huge smile as the two of them walked towards the front of the stage. Ferb smiled back but frowned again as soon as his brother turned his back.

They sat in their seats and munched out for a while, until the lights dimmed and the music picked up. The concert has begun.

Soon the band was running out and grabbing their instruments to start up the song. Phineas quickly stood to his feet and started clapping his hands to the beat. Ferb sunk down into his seat and started sipping at his soda. He glanced around at the band and was soon being drawn in by the music. The knot in his chest began to fade as he gained the courage to stand up and start clapping to the beat with Phineas.

The concert went on, and the two of them were having a great time. Ferb was smiling wide and even singing along to some of his favorite lyrics. Towards the end of the concert, Ferb felt his phone vibrating in his back pocket. He took out his phone and glanced at the caller ID. His heart nearly stopped when he saw the home number pop up. He looked at the time and saw that it was almost midnight. He gulped as he tapped his brother on the shoulder and showed him the phone. Phineas smiled and squinted at the phone. When he saw the number his smile faded into an 'Oh crap' look.

Ferb held his breath as he answered the phone, "Ello?"

He quickly pulled the phone away from his ear when he heard his dad burst into loud angry shouts. He couldn't comprehend what his dad was saying over the music so he quickly rose from his seat and ran towards one the exits. Phineas aw this and quickly ran after him.

Once they were in a somewhat quiet place, Ferb put his ear back up to the phone and spoke,

"Ello father…"

"Don't you 'ello father me'," Lawrence replied angrily, "where are you two? Do you even know what time it is?"

Ferb gulped and handed the phone to Phineas. Phineas nodded his head and started speaking,

"Hey dad, look we-"

"WHERE ARE YOU TWO?"

Phineas winced at his dad's tone and spoke nervously, "We're at a concert…"

"YOUR AT A CONCERT? ON A SCHOOL NIGHT?"

"We lost track of time dad… we're-"

"No more excuses, son! I want you two to come home right now!"

Phineas gulped and nodded his head, "Yeah sure, dad we'll be home in another half an hour."

"You'd better be… you two are in enough trouble as it is. Get. Home. NOW!"

"Yes dad, bye."

Phineas hung up the phone and handed it back to Ferb. He chuckled nervously, "In case it isn't obvious… we're in trouble."

Ferb clenched the phone in his hand and waited for the urge to punch his brother to fade. He breathed out heavily and shook his head,

"Let's just… go home."

The two walked back to the car and started driving off. Phineas tried to offer some friendly chitchat, but Ferb would have none of it. Why didn't he see this coming? Of course they would get caught, why did he let Phineas talk him into this? Now they were going to get reprimanded and punished for all of this. They're going to lose their freedom for the rest of their lives. Worst of all… underneath his father's harsh tone, Ferb could hear disappointment and regret in his father's voice. He had let down his own dad.

"Come on Ferb," Phineas spoke up, "it won't be too bad. Sure we'll be punished, but at least we'll-"

Ferb slammed his fist against the wheel, "Why did I let you talk me into this? I knew we would get caught, and now my dad is never going to trust me again!"

"Ferb I'm… I'm sorry…"

"You're only sorry for getting caught! I hate you Phineas Flynn!"

Phineas's eyes grew wide, "What? But Ferb-"

Suddenly something hit the car head on. The car went spinning and then flipped in the air multiple times before it landed upside down in the middle of the road. There was a sound of creaking metal and cars screeching to a stop inspect the damage.

Ferb moaned from where he was and fluttered his eyes open. His head felt sticky and wet, and he felt like he was going to pass out. Before he lost full consciousness, he heard a small weak voice call out,

"Ferb... I'm so sorry..."

And that's it for the first chapter. So what'd you think? Should I continue? No flames please, I burn easily! Thanks for reading, review?
