One mistake. Two boys. Five years. A lifetime of regret. A high school relationship was never supposed to be this deep. 5 years later, Naruto's still reeling from the explosive breakup. Sasunaru AU.

This is a story I felt I needed to get out. Possible triggers, mentions of noncon and emotional instability.

I'm never drinking again. My 21st birthday is going to suck.

That was Uzumaki Naruto's first thought as he woke up. He felt like he was still drunk, which he likely was considering he hadn't stopped pounding back drinks until well past 4 in the morning before he'd and it was… according to the clock on the wall, not even noon. He felt terribly nauseous but wasn't hungry at all. Little tidbits of the night before came back to him. At that moment, he hated the soccer team and their stupid parties and fucking Kiba for sneaking in all the drinks.

Speaking of… where was his sober companion? Unable to find his phone, Naruto rolled his way out of the bed before whimpering rather pathetically. "What the hell?"

His ass hurt like hell. Like, he'd definitely gotten fucked raw last night type of hell. And he regretted trying to stand because he instantly felt the sticky goo trying to leave his backside. He nearly collapsed at the sudden burning pain. He was quite naked in fact, and he knew all too well what he'd done.

Yet he wasn't concerned. Annoyed, but not concerned. "Dammit Sasuke, really?" He whined. Not only did he not remember it, but his bastard boyfriend had really done a number on him. Usually, Sasuke was careful about the prep work and protection. To think they'd done it in someone else's bed and that hardcore. He would be laughing if it didn't hurt so damn much. And his back! Oh god, his back.

Still not terribly clear-headed he wiped himself best he could on the sheets, ignoring the small tint of red, and was able to find his clothes. Or, what was left of them. His boxers and pants were fine but his beautiful orange shirt was nearly torn down the middle! "What the hell," he blinked. Okay, Sasuke was definitely drunk to pull that kind of shit. It explained the sore spot he felt on his shoulder. Damn, he was going to have a bruise.

After donning the shirt despite its deformity, Naruto stumbled out to find his boyfriend. He knew Sasuke wouldn't have left the party without him even if he was a bit of a bastard. He stumbled past a wasted Kiba in the hallway and nearly tripped over Sai's leg who was dozed off on the couch. As he kept moving he only saw a couple other people but some of them were far older, college-aged, and he didn't recognize any of them. Shrugging off the newcomers he eventually found a bathroom and managed to clean himself up a little. God, his throat was sore. Even his mouth tasted like-

He'd leave it there. Not glancing in the mirror he rubbed a sore spot on his jaw absentmindedly and made his way towards the back. The house was fucking huge, and it took five bedrooms before he finally found Sasuke.

He was beautiful. Just his torso was peeking out above dark blue sheets. Ivory skin, dark hair, perfect lips. A modern-day Snow White. His body was lithe and perfect and Naruto instantly lit up with a smile. "Wake up Teme! Why the hell did you-"

He stopped talking. Something stopped him from talking. At the same moment, Sasuke started to stir to his hyperactive voice so did something else in the bed. Naruto's eyes widened as another lump uncovered themselves from the sheets.

"S-Sakura-chan?" Naruto blurted out. "What the hell?"

A loud 'eeep' went through the room as Sakura quickly tried to cover her bare torso. Not that it meant much, Naruto was gay as they came. No, he was more interested in why she was in bed with HIS boyfriend than what her tits looked like (they looked good, he'd reflect objectively at another date).

But Naruto was, if nothing else, loyal and trusting. He took a deep breath and marched over to the side of the bed, hands on his hips in frustration. "Sasuke, explain."

Sasuke was staring up through slightly tired eyes that were slowly clearing. He sat right and ran a hand through his hair, sweeping back some of those sexy- no. Nope. Naruto was too upset to think about how hot his boyfriend was. "Hn."

"No, you don't get to one-syllable your way out of this. Sakura, what happened?"

Sakura glanced nervously between the two of them. "It- It isn't what it looks like-"

"Well, it looks an awful lot like Sasuke left me last night to go for a round with a girl," Naruto gave her sharp glare before turning to an impassive Sasuke. "So Mr. unemotional, wanna tell me what happened?"

"I slept with her." Sasuke stared him down evenly. And though Naruto was the one that should be pissed Sasuke looked more annoyed. No, there was something in his eyes that Naruto wanted to pretend he didn't see.

Naruto wouldn't believe it. "Very funny," Naruto said in a voice that said it was clearly not. "What happened? You stumble into the wrong bed? How much did you drink?"

"Not enough to not know better" Sasuke narrowed his eyes.

Now Naruto should, logically, be getting upset; should be screaming 'cheater' and all that. But after dating for 3 years, literally, since their first day of high school, Naruto was not willing to believe his boyfriend would cheat on him. They were in their final year, they had already passed the exams to K university together starting in spring. So Naruto tried again. "Sasuke… what's going on? Sakura?" He glanced at Sakura.

Her wide green eyes were brimming with tears. "Naruto I would never-"

"Shut up," Sasuke growled at her. "Yes, I slept with her Naruto. You know I can go for girls as well, I'm not completely inept like you."

Naruto's head started to pound, and it had nothing to do with his hangover. He had a good young liver and a little nausea was all he was getting from that. No, instead he felt like he was having an aneurysm.

Sasuke was taking advantage of his stupor and climbing out of bed in just his boxers. "And you know what Naruto? It was great. Much better than your loose ass. And she didn't make all those annoying noises. God, you sound disgusting in bed, did I ever tell you that? You moan like some chick it's disgusting!"

Naruto was shellshocked, and apparently so was Sakura as she stared, trapped by her own nudity as she was caught in the middle of some lovers spat.

Despite the stabs to the heart Naruto licked his lips and tried to find his voice. "S-Sasuke are you drunk? I-"

"Made me think about why I even put up with your annoying ass. Why the hell was I dating someone like you? Annoying, loud mouth, fat, god those scars on your cheek disgust me. Having sex with you was the worst. I'd have to imagine-"

Sasuke never got to finish his sentence. He was flat on the ground clutching his cheek and staring up at Naruto. Naruto was fuming. "What the fuck. Three years? Three fucking years and suddenly you decide you want to break up like this? What the hell. I can't believe I-"

"Don't act like you're not the one who-"

Ignoring everything Sasuke was trying to say Naruto continued. "Gave you my fucking virginity, three years of my life, and my dream school for you! You know what fine. Fuck you Sasuke. I hope you find someone you actually like next time, so you don't put up with them for three years. Sorry for being so disgusting." And with that, he stomped out. He ignored the cries from Sakura to stop.

No phone, no wallet, no shoes. Naruto decided to fuck all and took out of the house without any of it. He'd ask Kiba later. For now, he just needed to get home. To the hellhole he called home and the lump of stuffing he called a bed.

He was halfway down the road when a silver BMW pulled up. "Naruto!" Sakura called from the rolled down window. "Naruto please stop."

"What? So you can brag about fucking my- my ex-boyfriend?!" He spat. And regretted it instantly from the hurt look on her face.

"Naruto, please. Get in. Your house is 20 miles away. Let me drive you."

Reluctantly realizing his choices were slim he agreed and climbed into the passenger seat. Sakura sent him a look. "Naruto about last night. I really don't remember anything. But I don't feel… I- I know I never would have betrayed you two like that. I gave up to you three years ago, remember?"

Naruto tried a smile but failed. He did remember. Back when Naruto was just discovering his new sexuality Sasuke caught his eye. He'd gone after the boy with no constraints to society's norms and somehow convinced the school god to be with him. And Sakura, his best friend since middle school, had fully switched to supporting him. The same way he would have done if she was with him.

"I- I know Sakura. But it still hurts. I can't believe you- no, it's his fault. He took advantage of you. And I… I want to forgive you. I will. Just… not yet."

Sakura placed a hand on his as they started to drive down the road. "You're a much better person than I am Naruto. I have no idea what came over Sasuke. Did you two fight?"

Naruto shook his head. "That's the thing. We were great yesterday. Better than great. We were talking about renting an apartment closer to the university- you know how bad I want to get out of the slums. I even have a few printouts at home of places. Yesterday was so normal and then he said all that…"

"I think he was just saying it to be mean. You know you're the most desirable male in high school, don't you? You won king last year in case you forgot," Sakura teased. Slowly she started to get more pumped up. "Half the school population thinks you're the one that turned Sasuke gay. Tan, sunshine hair, sky eyes, fit. I have no idea where he got fat from. Those whiskers are hot as hell Chanara!"

Normally the complements would be sending Naruto's eager soaring. But the person whose opinion mattered most…

"Maybe he was just drunk Sakura. Maybe tomorrow he'll text me… he'll text me and… um... I-" his voice broke. But he wouldn't cry in front of Sakura.

Sakura fixed him with a look. "I want you to think about it Naruto. Even if he does apologize, would you take him back after all that? And your face..." She trailed off, looking sorry. "Was that him?"

Ignoring her last question and focusing on the first, Naruto realized he would. Because no matter what Sasuke put him through, no matter how sour the relationship, Naruto was completely dependant on his lover. His ex-lover.
