The Sweetest Sin

Author's Note: Thanks for the reviews, follows, favs, and clicks. I was really nervous about posting this story for obvious reasons. But the feedback has been positive, so I will continue it. Obviously, this is a story about fictional characters and in no way is intended to make a judgment on relationships like this in real life. Anyway please enjoy. Your reviews are greatly appreciated. :D

Chapter Notation: Not sure if Sasuke's dream really counts as a lime. But I labeled it that anyway. It's in italics and warnings are placed before and after. So if you want to skip it, you can with ease. Or if you are excited to see the dream, you'll know when it's coming. ^^

Chapter Two

The next morning, Itachi smiles. He was awake, but Sasuke was still sleeping. His baby brother had never been a morning person to put it mildly. If given a choice, he'd always sleep till noon or even later.

He was a natural night owl. Sasuke COULD get up earlier and still function, but he would much rather stay up all night and sleep away half the day. Itachi was perfectly fine with this.

"Beautiful." He murmurs almost reverently as he places a light kiss to his forehead.

It meant he could spend hours just watching Sasuke sleep. He was positively ethereal to look at when he was bathed in the morning light that streamed through the curtains of their window. Sasuke looked so peaceful while asleep and adorable when he was curled up against Itachi like a little kitten. He chuckles when he imagines what the dark haired ninja's reaction that description.

"Mmm." Sasuke murmurs and snuggles closer to that source of warmth.

Itachi decided to indulge himself. Sasuke was asleep. He could hold him to his heart's content. There was no harm in it, as long as Sasuke didn't wake up to find Itachi holding him in a lovers' embrace. So he wraps his arms around the other Uchiha in the bed and smiles. He wondered what Sasuke was dreaming about.

Warning Lime

"It's all in the wrist, Sasuke." Itachi instructs him in the proper way to throw a kunai.

"Okay!" He replies happily.

Of course he was happy. He was spending time with his big brother and Itachi was training him how to be a strong ninja, just like him. Nothing could have made the five year old happier, other than possibly his father's acknowledgement.

"I did it!" He cries out joyfully when he struck the target.

"Yes, you did. You deserve a reward." Itachi says and Sasuke blinks.

Itachi's voice was older now. He had been twelve a few minutes ago. But now his voice was that of an adult's.

He slowly turns around and blinks. Yeah, Itachi was 21 again. He looks down at him and notes he was also his real age. What the?

"A reward?" Sasuke asks.

"Of course." Itachi walks over to him and connects his lips with Sasuke's in a sensual, slow kiss.

"Itachi, we can't." He says, breaking the kiss and trying to back away.

He was stopped though. Something was behind him. Whatever it was, it was large and warm.

"Why not? Because you're brothers? Since when have you ever cared what others thought?" He hears Naruto's voice ask and eyes widen.

Dammit! Itachi had kissed him. Naruto had seen. Naruto was going to be disgusted with him. At least that's what he thought, until he felt the blonde's arms wrap around him and the warmth of his breath on his neck as the blonde whispers in his ear.

"Just relax. Who are they to judge any of us? They don't have the right to. Not after everything we've been through." He hears his best friend ask and he shivers at the seduction in his voice.

"He's a bit skittish. But he tastes so sweet." Itachi says, seemingly to be conspiring with Naruto?

"Well yeah. You are his brother. It's natural that he'd be a bit shocked at first." The blonde argues.

"Of course." Itachi says.

"Naruto?" Sasuke asks in confusion.

"We saved them all. The least they can do is let us love who we want to love. Just relax. Don't think. Just feel." Naruto tells him and kisses his neck, holding him tightly from behind.

"Nhh!" Sasuke moans and shivers, his neck had always been sensitive.

"That's better." Naruto growls approvingly and bites down on his collarbone lightly, sucking harshly.

"N-naruto." The younger Uchiha pants out and Itachi smiles, caressing his cheek.

"You should follow his advice, foolish little brother." He says and kisses him.

This time Sasuke went with it. It felt so good. Naruto's arms around him and mouth on his neck. Itachi's seductive kiss. He felt himself moan into the kiss and his lower half begin to respond. It was wrong, he knew that. But it felt so right.

End Lime

Meanwhile Naruto heads into the Uchiha house. Itachi and Sasuke had said he could come in whenever he wanted to. They'd sense him long before he ever knocked.

So he did exactly that. His mind was still reeling from the day before. He had half convinced himself it had all just been a dream.

"I do not! I just said that I love him like you do!" His words rang in his head.

"Exactly." Itachi's reply replayed in Naruto's head on a nearly endless loop.

Itachi was in love with Sasuke. Sasuke didn't know. Well at least Itachi didn't think that the younger Uchiha knew.

Naruto thought it was a fairly safe bet that if his best friend knew about his brother's feelings for him, Sasuke would have done or said something by now. So he conceded that the elder Uchiha was likely correct in his assumption. Still he was left feeling rather confused and shocked about the whole situation.

He looked around until he found them in the bedroom. Well one of the bedrooms. He wasn't sure if this was actually Sasuke's room or if it was Itachi's.

"Sasuke? Itachi?" He calls out.

He supposed it didn't matter. They were sleeping together anyway. Naruto mentally smacked himself when images of a far less innocent meaning of the phrase sleeping together danced across his mind.

"Shhh." Itachi says when Naruto peeks his head in.

Naruto couldn't help but blush. Sasuke was still asleep. He was laying curled up against Itachi so sweetly.

The notes that the younger man was squirming quite a bit. Sasuke must be dreaming about something. His face didn't seem distressed though. The blonde decided it probably wasn't a nightmare then.

"Nhh!" Sasuke moans and slowly his eyes open in confusion, they were ruby red and cloudy with desire.

Naruto had never seen what Sasuke looked like when he was asroused before. It took his breath away. Alright definitely NOT a nightmare then.

He guessed even Sasuke had wet dreams now and then. It was a shame that the blankets were covered over him. He could have gotten a hell of a view, Naruto was sure.

"Good morning, Sasuke." Itachi says and apparently he was going to pretend that Sasuke just hadn't moaned.

Naruto decides that was probably a good idea. God knows that he'd never seen Sasuke display anything resembling a sex drive before. This was actually a major breakthrough. He definitely didn't want to embarrass him about it.

"Morning." He says.

"Naruto is here." His brother informs him.

"Oh. Hey, loser. What are you doing here so early?" Sasuke asks and stretches, trying to have any excuse not to look the blonde in the eyes.

"Well you both have doctor appointments. I figured since it's my day off, I'd go with you. You know moral support and stuff." He says cheerfully.

"Itachi, do we have doctor appointments today?" Sasuke asks him sleepily.

"Hmm…it appears that we do." Itachi replies after looking at the calendar and noticing the writing on that day's section.

"Damn." Sasuke says.

"Yes. Well we should probably get out of bed or we'll be late. Tsunade is not a pleasant woman when she's kept waiting." He adds.

Sasuke and Naruto definitely couldn't argue with that. They head to the hospital. Naruto walked behind them. He knew it was a cheap trick. But damn it was a nice view. The brothers walked side by side, as if naturally synchronized.

"Let me see your arm, Sasuke." Tsunade says once they arrive.

He nodded and handed it to her. The blonde medic quickly undoes his bandages and looks. The First Hokage had a healthy tan. So it looked a bit odd to see that tanned arm on Sasuke's ivory cream colored body. But Naruto was glad that Sasuke had an arm back, no matter what color it was.

"It looks good so far. Try moving it." She says.

Sasuke flexes his arm. He shuts his eyes and grunts in pain. Tsunade stops him from moving it further.

"That's to be expected. It will hurt at first. For the next two weeks, at least twice a day I want you to flex both arms at 15 times. You need to get the chakra and blood circulating." She says.

"Got it." He says.

Tsunade then tends to Itachi. She was explaining his current condition. Naruto didn't understand a word of it. It was all medical jargon. Sasuke seemed to understand though.

"What did she just say?" He asks.

"Essentially, continue taking the medication she prescribed and to take it easy. Don't use his chakra yet. Get plenty of rest." He answers.

"That's what she said? How did you get that out of that?!" The blonde demands.

"I spent too much time around Kabuto. I picked up a few terms." He says.

"Wait, he trained you in medical jutsu?" Naruto asks.

"No. I don't have the patience for it. My chakra is too aggressive anyway." He says with a shrug.

"Chakra has a personality?!" The blonde asks.

"Not exactly. But it's the easiest way to explain it." He says.

"Oh alright. Hey, Itachi you wanna go get some food after this?" Naruto asks.

"Well I would like to have breakfast." Itachi muses.

"Great! So is he good to go, Granny Tsunade?" The blonde asks.

"Yes. But make sure he takes it easy. He's still recovering from a major illness." She warns them.

"I'll make sure he takes it easy." Sasuke promises.

They head off to a restaurant. Thankfully it wasn't the Ramen Shop for Sasuke's sanity's sake. Itachi had put his foot down and Naruto didn't want to argue with someone who was enduring a difficult recovery process.

"I'll go place our order." Naruto says and heads off.

"Itachi…I need help." Sasuke whispers so quietly that even Itachi's keen hearing barely picked it up and he was sitting right next to him.

"What is it?" He asks genuinely concerned.

"I had a dream about Naruto." He says.

"I figured as much." Itachi replies.

Itachi mentally winced. He had been mentally preparing for this. His brother was clearly in love with Naruto.

Naruto was a good man. He'd make Sasuke happy. He was Sasuke's brother. The younger Uchiha returning his love had never been a real possibility. But knowing that in his head and hearing it in reality were two apparently very different things to his heart.

"He's not even gay." Sasuke states.

"I told you that I saw him looking at your ass. He's definitely gay or at the very least bisexual. In either case, his sexual orientation wouldn't be the thing that keeps you apart. Sasuke, like I said before our lives are generally rather short. It's important to grab onto whatever or whoever makes you happy while you can." He advises.

"It wasn't just Naruto though. There was a second person. He kissed me and Naruto held me while he did it. They knew about each other." He says.

"A second person?" Itachi asks.

Sasuke nods. He couldn't tell his brother that it was him. But maybe Itachi would be able to help him anyway.

"And this second person was also male, you said?" The elder Uchiha inquires.

"Yes." The younger man answers.

"I surmise you feel guilty about finding them both desirable?" Itachi inquires.

"Yes. It's emotional cheating." Sasuke says.

"Sasuke you can't cheat on someone you aren't even officially in a relationship with. Don't be silly." He chides him.

"I know. But still…it's wrong." His little brother says and he looked so forlorn that it took all of Itachi's control not to pull him into his arms and hug him tightly.

"Monogamy isn't exactly a natural condition for humans. We've trained ourselves to believe that it is. It likely began thousands of years ago as a way to ensure that the children a man was raising where his own. It's possible, healthy to be attracted to more than one person." Itachi reassures him.

"Maybe. Feeling physical attraction one thing. But acting on it is another. Naruto deserves someone who is faithful and if I'm thinking about someone else part of the time, I'm not giving him what he needs." Sasuke mutters.

"Who do you care for more?" Itachi asks.

"I care for them both equally, in different ways." He answers.

"With Naruto I know the feeling is mutual. Do you believe the second man returns your feelings?" He asks.

"Not like that. He doesn't love me THAT way." Sasuke answers automatically.

"Then I fail to see the issue. Tell Naruto of your feelings." Itachi says.

"You don't think it's wrong?" Sasuke asks.

"Sasuke it's perfectly natural to be sexually attracted to more than one person. It's kinda what kept our species going until very recently. But if it's that big a concern, let's ask Naruto about the matter." He says when the blonde returns with their food.

"Hey, sorry it took so long. There was a really big line." He says cheerfully.

"Oh no problem. Sasuke and I were just having a discussion about society's insistence on monogamy." He says.

"Huh?" Naruto asks.

"What I mean is Sasuke views it wrong to be in love or attracted to two people at the same time because society has drilled this notion into his head. What are your thoughts on the matter?" He asks.

Sasuke glowers at Itachi and kicks him under the table. Itachi wasn't deterred though. He just smiles pleasantly.

"Oh…well yeah. I mean…it's normal to find more than one person attractive. I guess it's okay to be in love with two people at the same time as long as you are honest about it?" He asks.

"See, Sasuke?" Itachi says smugly.

"Something going on, Sasuke?" Naruto asks.

"No. Nothing. Just my brother being ANNOYING." Sasuke says and twitches.

"I have to blame myself partially for this. His insecurity is clearly the result of my having…deceived him about the fate of our clan. It's only natural that he would have trouble forming attachments." Itachi says.

"Whoa Itachi! I don't know what's going on here. But Sasuke is doing that twitching thing he does before he fires off a Chidori. You really aren't in any shape for a brawl. Maybe you should head home and I'll try to calm him down." Naruto suggests.

"You're right. Sasuke, you really do need to work on that temper of yours. You'll never make a good wife otherwise." He says with a smirk and flits off.

"THAT'S IT!" Sasuke says and he was about to race off after Itachi, when Naruto held him back.

"He's just teasing you. Probably thinks if he goads you into it, you'll confess to whoever it is." The blonde says.

"Probably. Itachi is good at mind games like that." Sasuke says with a sigh.

"Seriously, whoever she is you should tell her. She's really lucky." Naruto says, pays for their bill, and leads Sasuke to the training grounds.

Naruto knew Sasuke's temper. There was no way he wanted the man near civilians when he lost it. And he could recognize now when an Uchiha Temper Tantrum was brewing.

"…" Sasuke goes suspiciously quiet.

"Oh come on. It can't be that bad. She's not married, is she?" He asks.

"No. They aren't married." Sasuke answers.

"Good. She's not already with someone, right?" The blonde continues.

"No. And…it's not a she." He mutters.

"Ohhh. I mean I always kinda wondered. You never really looked at girls. Does he not like guys?" Naruto asks.

"I think he's straight. Itachi disagrees." Sasuke says.

"Well if he's gay and not taken, he'd be an idiot not to be interested." Naruto says cheerfully.

"Naruto, you're saying that because you're my friend and you don't know who he is." Sasuke says.

"Well yeah, I don't know who he is! I would if you just told me. I'm not going to tell anyone, Sasuke. I wouldn't betray your trust like that. I think it's great that you finally like someone." He says.

"I don't LIKE him. I'm not some Genin with a crush. My feelings aren't that superficial." Sasuke hisses at him.

"Whoa! Easy there bastard! You're really serious about this. Damn. I didn't mean to you know…diminish it." Naruto says.

"You ALWAYS do." Sasuke snaps at him.

"What's that supposed to mean?!" The blonde growls.

"I asked you once why you were so obsessed with me. You said, "Because you're my friend!" Now you actually have the gall to say, "I'm glad that you finally LIKE someone." You ALWAYS diminish my feelings and yours. I have no idea why I fell in love with such an oblivious, fucking moron! But it hurts and I want it to stop!" He snarls at him.

"Wait…say that again." Naruto says.

"That you are an oblivious, fucking moron?" Sasuke asks.

"No…the part before that." The blonde says.

"I didn't mean to say that…" The youngest Uchiha says and frankly looks horrified at his "confession."

"But did you mean it?" Naruto asks and he flits ahead of Sasuke, blocking his path.

He knew Sasuke. The man ran from anything emotional. He wouldn't bat an eyelash at facing Madara Uchiha. But the SECOND emotions were involved, he'd bolt. Naruto wouldn't let him. Not this time.

"I did. I know that you like women. I'm not going to force the issue. I promise that I won't bring it up again. Can we just forget that I s-" Sasuke starts to ramble off an explanation but is cut off by Naruto's kiss.

Sasuke gasps in shock. That was all the invitation Naruto needed to deepen the kiss. Sasuke loved him.

SASUKE SAID HE LOVED HIM! He wasn't going to give Sasuke another chance to take it back. He pushes him against a tree and never breaks the kiss.

Sasuke moans into it and kisses back. He tries to wrap his arms around Naruto's neck, but his replaced limb was still bandaged and felt awkward. He didn't care though. Fuck Naruto kissed like he fought, hard and with everything he had.

"You taste so good." Naruto breaks the kiss long enough to murmur before recapturing his lips again quickly.

Sasuke thought the same thing as Naruto. For some reason, he tasted like oranges. It was refreshing and pure, unique just like the man kissing him. He groans when he feels Naruto's tongue touch his, setting off a thousand fireworks inside him. So fucking GOOD.

Cinnamon and chocolate covered cherries, Naruto decided. That's what Sasuke tasted like. Hot and unexpectedly sweet. Could kisses feel luxurious? With Sasuke, they could.

He wanted more so he added tongue to the kiss. Naruto was in Heaven with the other ninja responded in kind. FUCK. The blonde squirms as he felt himself get aroused very quickly.

"Naruto, I n-eed to breathe." Sasuke says, after lightly shoving him away.

"Oh yeah. K-inda forgot about that." Naruto says, equally breathless.

"I realize that the two of you are new to relationships, but here is a helpful tip. You can breathe through your nose while you kiss." Itachi's voice calls out. (It seemed he had followed them.)

"Itachi!" Sasuke says.

"Just trying to be helpful." He says cheerfully.

"Oh um thanks. Great tip." Naruto says.

Itachi looks at them. While he was able to hide his feelings on the outside, on the inside he was conflicted. He WANTED this to happen, didn't he? Sasuke would be happy with Naruto. He'd never consider a relationship with his own brother. It wasn't as if Itachi had a real chance.

He couldn't help but feel a little resentful. If positions had been reversed, Itachi never would have made Sasuke wait this long. He would have already had him in his arms and wanting for NOTHING a long time ago.

Itachi pushes the thought down. He knew it was being ridiculous. Besides, Naruto was equally desirable as Sasuke…though in different ways. And he knew he couldn't have either. That fact was hard to swallow.

"You're welcome. I think I shall go visit Kisame. You two can have some privacy. It is after all a special night. The night you confessed your feelings for each other." He says and turns to head off.

"Itachi!" Sasuke cries out.

"Yes?" He asks and turns around.

"Thanks." Sasuke says and his eyes soften as he offers his brother a small smile.

"You're welcome." He says and heads off.

Naruto quickly teleports him and Sasuke back to the Uchiha brothers' house. He catches Sasuke before he fell over. He probably should have warned him that he was planning to teleport, but he was just too excited.

"How long?" Naruto asks as he pins Sasuke against the couch, so that he was laying on his back.

"Awhile." Sasuke answers vaguely.

"Why didn't you say anything and how long is awhile?" Naruto asks and kisses Sasuke's neck.

He didn't know why exactly, but he really wanted to mark up that creamy pale neck of his. Maybe it was just his irritation from the fact that Orochimaru had once bitten Sasuke there and placed a curse mark on him. Maybe it was a fox thing from Kyubbi. Maybe Naruto just had a necking fetish. He didn't care at the moment. He just knew he wanted to mark Sasuke in some way.

"Consciously? Since…the new Team Seven tracked me down. I was…so happy to see you. More than I should have been. I think that's why I taunted you then. I didn't know how to deal with it." Sasuke says.

"That long? For me it was when you told me you were going on your Journey with Itachi. It hurt so much. You were finally back but you were leaving again. I wanted to go with you, more than anything. But you said I had nothing to do with your sins and I knew how much you and Itachi needed to go." He says with a sigh.

"You didn't have anything to do with my sins. You do, however, have everything to do with this." Sasuke says, arching underneath Naruto, and grinding their clothed erections against each other.

"FUCK! Ss-asuke!" Naruto groans and pants.

It felt so good. He'd never felt anything like that before. He should have known that Sasuke was going to be a sneaky bastard. Sasuke used the moment to flip them, so he was on top.

"That was such a cheap trick!" Naruto growls from underneath him.

"Maybe. But it worked." He says with a sexy smirk.

Naruto leaned up slightly and kisses Sasuke passionately. He didn't mind Sasuke being on top at least for now. He just wanted to feel his touch and to touch him.

Sasuke moans and kisses back. He didn't think that he'd ever get enough of it. They probably would have gotten along much better as Genin, if Sasuke had been aware of what else Naruto could do with his mouth other than talking excessively. Which did bring to mind a few…interesting ideas about what else the blonde might be able to do with his mouth.

"You know, I've wanted to say something for awhile. But I always thought that you'd punch me." Naruto murmurs, breaking the kiss, and caressing Sasuke's cheek.

"What is it?" He asks.

"You are way too beautiful to be a man." The blonde admits.

"You really are such an idiot. But you're my idiot." Sasuke says and kisses him.

"And you are such a bastard. But you're my bastard." Naruto replies cheerfully and returns the kiss.

They spent the rest of the night kissing, grabbing, and caressing each other. Both enjoying exploring each other in a brand new way, but daring to take it further.

In the morning, Sasuke headed off. He had a mission to do. It was just guard duty. He'd be back in a few hours, the younger Uchiha promised the blonde who had frisked him rather thoroughly before he departed.

"Judging by the number of lovebites currently adorning my brother's neck, I'd say that you two had a mutually enjoyable evening?" Itachi asks.

"It was amazing. Thank you for goading him like that. I don't think either of us would have admitted how we felt without you. You're the best!" He says with a smile.

"If that were the case, it would be my arms that he sought out in his WAKING hours." Itachi replies.

His tone was neutral. But somehow Naruto still picked up on one undeniable fact. Itachi Uchiha was jealous. Very jealous. Shit.

"This has to be hard for you. I'm sorry, Itachi. I can't imagine what it must be like for you. I was scared to tell him how I felt. But you…you'll never get that chance." Naruto offers sympathetically.

"I caused him so much pain. I know that I don't deserve him. Still it is harder than I thought it would be to watch him with someone else. Even if that someone else is someone that I greatly admire." He says.

"Did you really mean what you said earlier? That you could love me?" The blonde asks.

"I meant it. I've spent most of my life deceiving people for their own good. Now that I'm free to tell the truth, I try not to make a habit out of lying." He replies.

"Good. You were having a debate with Sasuke about whether it's wrong to love two people. Was that just because of your feelings or did Sasuke ask for advice?" He questions.

"Sasuke had a dream. In this dream he was being kissed by one man and another was holding him while kissing his neck. The man behind him was you. He would not tell me who the first was." Itachi answers.

"Three guesses who the first man was then." Naruto mutters.

Itachi blinks. He didn't want to get his hopes up. There was no possible way that Sasuke could ever feel the same way around him. He was far too constricted by the norms of society.

"I think that maybe…we can all get what we want. I'm not going to lie. I love Sasuke. I think I always have. I'd die for him. But…I feel something strong for you. And I like the thought of seeing you two like that. I think we could all be happy." Naruto says.

"You would share him with me?" Itachi asks in disbelief.

"Yeah. Not only that though. I'd want us all to be in a REAL relationship. No third wheel." He says.

"I'll admit that the possibility does intrigue me greatly, but he'd never agree to such a thing." Itachi warns him.

"I don't know. I didn't think that he'd ever love me back. But he does. He might surprise you." Naruto says with a grin.

Itachi smiles softly. He hoped with everything fiber of his being that Naruto was right. The blue eyed man had a way of making the impossible, possible.

Naruto he was beginning to believe could do anything he set his mind to. And if he set his mind to convincing Sasuke to enter into an unconventional relationship, perhaps he'd actually succeed.
