Disclaimer: I attempted to snag Sai and I was caught by security on the way out, one day Masashi Kishimoto he will be mine!

Now he was very sure that something was very wrong with him, he had been thinking that for awhile but now it was confirmed. Confirmed because he was looking at his fellow teammate and feeling incredibly hot, and it was making his head swim. In fact staring at his teammate was not only making his feel hot, it was making him dizzy, and also made his stomach clench uncomfortably. He could feel himself pant and his teammate staring oddly at him, shaking his head only made it worse and he waved his hands for a break. Closing his eyes and laying back he attempted to slow his heart and breathing and to cool down. After a few minutes he felt himself shudder and suddenly he felt tired and he weakly got up.

"Ne Sasuke I m not feeling too hot today I think I ll head home for today"

'Feeling too hot more like I'

Feeling cold calculating eyes on him he turned to face his teammate, Sasuke Uchiha and he looked annoyed and somewhat concerned all at the same time. They had been best friends and rivals for as long as he could remember, now they were chunin s and worked together perfectly. Both seventeen now he had finally accepted that Sakura was not going return his feelings and now she just a friend, a violent friend. No one had ever caught his fancy and he was perfectly content training everyday with Sasuke, and doing missions.

In fact since he was finally able to retrieve Sasuke when he was in Orochimaru s care, their relation has only gotten better. Though sometimes the lingering curse mark did give them a bought of trouble now and then but he was always there to set him straight or cover for him while he tried to keep the mark in check. In some ways they haven t changed all that much, he was still training to be hokage and to finally beat Sasuke. They still argued every day, Sasuke was still a cold hearted bastard and grudgingly he was still a loud mouthed ninja.

"Dobe, I think you should go see Tsunade, you ve been tiring out too much lately" Sasuke looked at him and for a moment he could have sworn his eyes softened slightly before they become hard and cold again.

"Shut up teme I'm fine I just need rest" Then he stared at the ground because it looked really fuzzy, then he was on the ground because his legs had suddenly given out. Then he was feeling all hot again and he didn t know why and suddenly he just wanted to be with someone. Panting he tried to call out but his mouth was dry and his thoughts weren t coherent anymore. He just wanted it to stop he was all uncomfortable everywhere, he just wanted it to all stop. He vaguely felt someone picking him up and the intensity of the ravishing heat dulled but in some parts it had intensified.

"Sas-sasuke?" He questioned and he looked up to see concerned onyx orbs staring down at him.

"Sleep dobe I gotcha" Was the reply given to him and he had just enough energy to snort back.

"Don t call me dobe," He mumbled back before drifting off to sleep, because after all Sasuke had him and he trusted Sasuke with his life.

It would have been annoying and unworthy of him had it been anyone else, but because it was Naruto he had to make sure the dumb blonde was okay. Because Naruto had always been there for him, even when he didn t want his help he gave it to him anyway. Brought him back from the depths of darkness several times, until he was flitting on its edges. Then until he was far away from most of the darkness all together, since then he considered Naruto a true friend.

Though he rather be caught dead than admit that aloud, especially to Naruto himself. Taking a moment he looked down at Naruto in his arms, he could feel the heat rising from him. Damn idiot must be sick and still attempting to train anyway Then again thinking back Naruto had been steadily getting worse the last few weeks. Growing tired easily, constantly getting hot and dizzy and the poor boy seemed to be getting frustrated at his inability just get better.

Which was strange because after all if he was sick kyuubi would have already fixed that, unless he had been exhausted of chakra already. That made a cog starting rolling in Sasuke s head, if it wasn t a natural sickness then that meant that somehow it was Kyuubi s fault that Naruto was sick! That got him moving faster to the hokage s office, since she knew all things kyuubi related. Frowning he looked down again as Naruto had began clutching his shirt in his sleep and whimpering. It almost sounded liked pained whimpers and he wondered briefly whether kyuubi was doing something to hurt Naruto. That had him growling, he didn t like that one bit no one was allowed to hurt Naruto, excluding himself of course.

"Hush Naruto I told you already I got you," He mumbled quietly and was surprised when Naruto went completely slack. He stopped his pace and looked own in mute fascination as Naruto had slipped into a deep peaceful sleep. Putting a pale hand on Naruto forehead he frowned as it seemed Naruto had calmed back down, he still had a small fever but he no longer felt hot. Debating whether to continue to the hokage or not he let out a hiss of annoyance and changed directions.

"Pain in the ass," Talking to no one in particular since he was alone, aside from the sleeping idiot in his arms. Luckily it was still early morning so not many people were out, so he could jump rooftops with practiced ease as he neared the edge of the village. Landing at the front gates of the familiar lonely gates of the Uchiha grounds, he pushed through and walked down the paths. He felt himself relax slightly, after all no one was here, no one to judge him, no one at all but himself. Walking up to the front door he fumbled around till he was able to grasp the doorknob.

Walking in he headed straight upstairs and shuddered and made a mental note to keep his house at a warmer temperature. Searching his eyes feel on the nearest open door and quickly walked in and carefully laid Naruto out on the bed and threw a small blanket on him too keep him from getting too cold but not too hot either. Turning around he groaned, how could he have not realized this was his room.

Although he hadn t planned on going back to sleep since it was routine to wake up early and train with Naruto, sleep sounded like a great idea. Mentally debating whether to move Naruto to another bedroom he shook his head and decided to leave him there and sleep in the bedroom down the hall. Gathering himself up he headed there and not even bothering to strip any clothing just fall upon the bed and fell asleep. His last thoughts being all about the blonde in his room sleeping in his bed, and how much trouble he was going to be in once he woke up.

After several long hours of sleep Naruto s sleepy mind began to awaken, and he grunted because he felt utterly at ease. In fact laying there he felt totally at peace and he felt well rested, which he hadn t felt for the last couple of weeks. Breathing in heavily he smelled something awfully familiar, it tickled his senses and it was slightly sweet but more on the spicy side. Frowning in slightly he tried to place the smell because he Knew that smell, mind clearing up somewhat he deepened his frown. It was Sasuke's scent, and that caused him to open his eyes and look around. Recognizing the room instantly he sat up quickly and then grunted when his head spinned on him. Looking around he nodded to himself Oh yea this is definitely Sasuke s room alright, its way too clean not to be . Dragging his feet to the floor he sat a moment before standing and looking around for a clock, and when he found it he let out a gasp.

'Holy shit it s already five!' He panicked, it had been only six when he had gotten up to train with Sasuke, and he guessed they trained for barely an hour before he passed out. Cursing and feeling a faint blush of embarrassment rise, he walked out of the room wondering where Sasuke was so he could thank Sasuke. Squinting his eyes in thought he looked down the hall where one of the doors was casually open, walking in he almost yelled before he shut his mouth.

Looking toward the bed at the end of the room, he saw a sleeping form sprawled out in comfort. Walking over quietly he looked down and observed Sasuke who looked like he was sleeping peacefully, because he was frowning or glaring in sleep. Smiling to himself and feeling himself becoming content looking at Sasuke, he was happy that Sasuke could sleep without much hassle. When they were younger and on missions while he slept he would always frown in his sleep and sometime whimper in pain or fear.

He had even caught him crying a few times and even waking up completely fearful, over the years Sasuke s nightmares haunted him less and less. Looking down he felt warmth spread through him, but it was different then what he had been feeling lately. It felt comforting and happy but he couldn t place what it was and it confused him grunting he exited the room and waltzed downstairs. He needed to know what was wrong with him now, he was seeing the old hag.

"See ya later teme" He whispered before closing the front door and running toward the tower. The evening was beginning to chill and he was glad he still had his jacket on to keep him warm. Seeing the town colors blur past him he reached the tower with minimal effort and walked right into the office without much trouble, because the guards wouldn t dare stop him. Though he could tell some really wanted to but it would only be to irritate him. After all he s done there were still a lot of villagers and other elite ninja that refused to accept him as a human being, they only saw kyuubi.

"Hey old hag" He said seriously and Tsunade turned to scowl at him but he could see the warmth in her eyes and he couldn t help but smile.

"Ya brat where the hell have you been today? she said irritated with a slight undertone of worry, and sheepishly he put his hands behind his head.

I sorta passed out while training with Sasuke this morning and I guess he took me to his place to rest, I just woke up" He explained and Tsunade narrowed her eyes.

"You have to be more careful after all if training with Sasuke is too rough I told you to be careful around him!" Anger rose from him and he snapped back defending his friend, even after all this time she still thought like that.

"Damn it I told you Sasuke isn t trying to kill me anymore I wish you would trust him more, this is my best friend you re insulting. He s been back for three whole years and you still look at him like his gunna jump me and stab a damned kunai in my heart. There are few people I completely trust and I trust Sasuke with my life give him the respect he deserves already because he sure as hell doesn t deserve the cold treatment you all give him!" He heaved from effort and hadn t realized that his voice had risen until he was yelling, but he wasn t going to apologize for it.

"I just I just worry about you kiddo I almost lost you twice because of him, and after the being with Orochimaru for as long as he did. Can you really blame me for being so suspicious I just don t want to see him hurt you again" she said coolly but she didn t look the least bit sorry either, and he understood he really did but that didn t make him any more forgiving of it. It was time that she started truly trusting Sasuke and he would discuss it later with her, but now is not the time.

"I will not let this go but that s not why I'm here He began and crossed his arms in a gesture of discomfort. Baa-chan there's something going on with me and I need to know what it is before I go insane and useless"

"Naruto whats going on? Does this have any relation to why you passed out today?" he sighed heavily and prepared to speak what he had been trying to avoid.

"For the last few weeks I ve been having heat flashes, dizzy spells and I feel all funny. I've been tiring out quickly and after having my little spells I feel completely worn out, I feel irritated and I want to know what the hell is wrong with me" she looked at him hard for a moment before speaking.

"Funny how exactly I need details"

"I don t know , he thought a moment and briefly thought about the fact Sasuke always was there, in fact just staring at Sasuke triggered it half the time. It's just like I don t know sometime I'll be near Sasuke, or I'll look at him and suddenly I get really hot and I get this weird feeling in my stomach and I can't think straight and I can't walk either and my heart races and-" He paused because he was getting all hot again just talking about him, and thinking about Sasuke more was making it worse.

Tsunade was on him like a hawk putting her hands on him with calculating eyes, taking in every detail of his body. He felt the touches and for some reason it felt terribly wrong and he growled and slapped her hand away. Panting he attempted to cool himself down and after a good ten minutes he was exhausted and sitting in a chair. Tsunade had been watching quietly with a mixture of amusement and worry plastered on her face.

"Goodness why didn t you come see me sooner brat, I know what's wrong with you"

"Then tell me already" he Snapped his temper short enough as is, because he was so damn frustrated.

"Your you're in heat Naruto" she said carefully slow and was watching for his reaction, and he was dumbfounded.

"I'm what!" He questioned and turned to her for an explanation to which she sighed heavily and sat back down."

Heat, it's normally term to describe mammals when it comes time to mate every year or as cases may be several times a year. You Naruto are being affected by kyuubi s instinct to search out a mate, that's why you get all hot and flustered, and get tired from effort. I ve read about this is some scrolls we have but I never seen it, and because your human its making you act all weird basically you have a need for sex and your irritated because you re not getting any" Head swimming at all of this he asked another question.

"But why is it around Sasuke" He whined and Tsunade looked at him a moment before answering.

"Normally in the animal world, said animals fight off other rivals to prove that they are the strongest and will produce the healthiest offspring. And females in particular are also very picky and will only mate with who they deemed the strongest. Sasuke and you are close and it s safe to say that you two are the strongest ninja in this village so unconsciously your instincts are telling you that Sasuke is the best choice mate wise for you" He sputtered and blushed furiously this information was all new to him, but in the animal perspective it made a lot of sense.

"So basically because of kyuubi I have animal in this case happens to be going into heat, therefore I ve been unconsciously attracted to the strongest person in the village which besides me is Sasuke, so what your telling me is that to get rid of this," he waved to himself his eyes wide in astonishment. "Is basically having sex with my best friend?"

"More or less yes, but you don t have to it should go away within the next month but until it does your going to be pent up and not going to be the nicest person to be around. In fact you should probably avoid Sasuke too" Eyes narrowing and gleaming with an untold message which did not go unnoticed by Naruto and he narrowed his eyes back at her.

"I'm not going to avoid Sasuke because I m sexually frustrated, besides he won t hurt me not purposely anyway. I'll just have to try to control the urges now that I know what they are I think I'll go now"

Without any more words he walked out of the office and headed outside surprised to see how dark it was already. The air was cold and nipped his face but he didn t feel like going home and he didn t feel like talking to anyone. It was scary to think he was attracted to Sasuke and that the last few weeks somewhere in his conscience he had wanted to bed Sasuke. Sure Sasuke was handsome, he was definitely strong and his only equal in battle, but he was also a bastard. Well not all the time he knew that, he still acted like a cold bastard but he knew better he was nice, and caring just no one really saw it. If someone took the time too actually look him in those beautiful onyx eyes they would know. Did he just call Sasuke's eyes beautiful yes yes he did was his instincts talking or maybe did he like Sasuke?

Hmmm I'm not sure how it turned out but I liked it I hope you did also because my friends there is much more to come -pervy thoughts- heh anyway I already have the second chapter pretty much written so it should be up in a few days. You should all review it motivates me a lot but then again what writer doesn't reviews? Find me one and I will give you a cookie cause I haven't seen one yet
