Summary: Nature always comes back to bite you in the ass. Kiba and Naruto find that out the hard way when they both come into heat – at the same time.

Part 1: Kiba's In Heat

Konoha was quiet around this time of the year. There were no major wars going on and the ninja missions were small and not very dangerous. The new students at the Academy were hyped up as they wondered about becoming a full-fledged ninja, and each of them took to training night and day so that one day they could become strong fighters for their village.

Many of the other ninja were either away on missions, recovering from missions, or simply training in their spare time. Amongst those training ninja was Inuzuka Kiba, a young Chuunin. He had grown taller and had matured a lot since his Genin days, and – according to many of the kunoichi in Konoha – had become rather striking in his looks. Accompanied by his dog, Akamaru, who had grown impossibly big in the space of two or three years, he was quite the young man.

He'd planned to rise early that morning so he could fit in some training before succumbing to his duties as an Inuzuka – it was his turn to clean out the dog house, a task which even the most feral Inuzuka dreaded. However, it was not to happen, as when he awoke to the sound of his alarm – and the wet tongue on his face – he felt like his entire body was on fire.

At first he believed he was sick – after all, he and Akamaru had spent a lot of time in the water the day before, and had probably caught a cold or something. But when Akamaru jumped off his bed with a strange whine, followed by a harsh growl, he knew it wasn't any sickness. Shrugging it off as nothing, he dressed in a hurry and ran to the nearest training area, the big white dog in tow.

He couldn't focus on training at all. His mind was distracted something terrible, and he was finding it hard to do anything more than trip over his own feet and give the trees new breathing holes. All of his kunai and shuriken missed the targets completely – something that was considered a sin in the Chuunin world – and he couldn't focus his chakra properly. That, and Akamaru seemed to be keeping a certain amount of distance from him.

Deciding that a cold shower might be useful, he left the training area and turned towards the river. He came across Sakura and Ino on the way, arguing over something – most likely Sasuke, though their arguments had toned down slightly since they had both become Chuunin. They spotted him and lifted their arms in greeting. Smiling, he walked over.

"Hey, Kiba." Sakura smiled. "Where you headed?" Kiba grinned.

"To the river." He explained. He felt his eyes lower from her face and mentally slapped himself. "I'm going to cool off. You ladies wanna join me?" The question came out before he could stop it. Both of them looked utterly surprised. "I, uh… I'm sorry, I didn't mean to… Bye!" He quickly ran off, leaving behind two stunned kunoichi.

As he walked hurriedly towards the river, he was mentally kicking himself. What was he thinking? Why did he ask them that? He'd never seen either of them as anything more than friends. He stopped dead in his tracks as the thought crossed his mind of what he might say to Hinata.

"I have to avoid her today. Who knows what will happen to her if I hint at anything like… that." He murmured aloud. Akamaru whined again, and Kiba frowned. He didn't understand Akamaru's behaviour. He'd never been like this before. He made a mental note to ask Hana to take a look at him when he got back to the Inuzuka district. With that thought in mind, he took off for the river at a run. He definitely needed to cool off.

Two hours later

Kiba stumbled through the gates of the Inuzuka district, looking as though he'd just returned from a heavy spar. His breath was coming in sharp pants, and his face was flushed. His hair was tousled and his clothes ruffled, and there was an unusual gleam in his eyes. Akamaru did not walk beside him, nor anywhere near him. His whines attracted the attention of the other dogs, and soon the Inuzuka pack was picking up Akamaru's words.

When he at last managed to get to his house, Kiba was acting even more strangely. His mother and sister, alerted by the Haimaru Brothers, met him at their door. They took one look at his rumpled appearance and exchanged a knowing look. Akamaru bounded up to Hana and reared up onto his back paws. She took his front paws in her hands and listened as he barked out what he wanted to say. Kiba could not comprehend anything. He just had this strange, burning urge…

"Kiba?" Hana was crouching in front of him now, trying to get his attention. When he lifted his head and she saw the glazed look in his eyes, she knew exactly what was wrong. "Kiba, listen to me. How do you feel?" He growled, low and long, and she raised her eyebrows with a smirk.

"Need… something… anything…" He gasped. "Too… hot." He was stripping his jacket now, revealing a toned torso beneath a thin fishnet shirt. Tsume watched her son and nodded once to herself. Then she was walking over and taking Kiba by his shirt and hauling him inside. Guiding him through the house, she pushed him down into the large tub of water that Hana had been bathing her dogs in only moments earlier. The sudden cold water brought Kiba back to his senses.

"Now listen up, pup." Tsume barked. "Your body is going through a change. I've been waiting for it, actually. It's hard to tell when it's going to happen, since all pups are different. You're about the average age, I'd say." Kiba looked up at his mother, confused.

"What? Why am I… like this?" He asked, slightly embarrassed. He did not want to admit to his mother than he was incredibly horny and felt like he would sleep with anything that had legs and a pulse.

"You're a young male, still ripe from pre-teen-hood. Your hormones are raging in that body of yours." Tsume leant down to stare her son in the face. "You're in heat, pup."

"In… heat?" Kiba gasped; face turning the colour of tomatoes. "But… how do I… get rid of it?" Hana laughed from the doorway.

"You'll be stuck like this for about a month or so, otouto-chan." She explained. "It's that time of the year, that's all."

"She's right. Normally there will be a few other Inuzuka's going through this about the same time as you. All we have to do is find one, preferably not too closely related, and then you'll be satisfied for a short while." Tsume added. Kiba looked confused again.

"To still the hormones for a short period, you have to sleep with someone." Hana said bluntly. Kiba turned an even brighter shade of red.

"Nee-chan!" He exclaimed, incredibly embarrassed. She laughed and walked over to ruffle his hair.

"Hey, I went through it too." She smiled. "Of course, I had Amai-kun by then. He sure helped a lot."

"Oh! Is that why you two were always-," A swift cuff to the head cut Kiba off mid-sentence. "So what… do I just have to… well… y'know?"

"Yes. Do you have a girlfriend or someone close to you?" Tsume asked sharply, always straight to the point. "Otherwise we need to find you an Inuzuka girl." Kiba quickly thought over all the girls he knew, and sighed. None of them were particularly close to him except Hinata, and there was no way he was going to…

"No. There's no one that I can think of." He told her.

"Right. Well, I'm off to search for an Inuzuka girl in the same position as you. That way, we deal with two problems at once." Tsume quickly made her exit, leaving Hana alone with Kiba.

"You know, otouto-chan, it doesn't have to be a girl." She said slyly. "I didn't want to mention it in front of Kaa-san, but I know you prefer boys." Kiba dared not ask how she knew about his… preferences. Sisters seemed to know everything, especially older sisters. "Is there any boys you're close to?" Instantly Kiba thought of Shikamaru, Shino, Chouji and Naruto. Asides from Shino, they'd all been friends since they were young boys in the Academy. Chouji wasn't really his type, and Shino was too much like his best friend. That just left the cloud-watcher and the hyperactive ninja.

"I… don't know." He admitted. Would either of them do something like that for him? No, he couldn't even tell them that he was… what would they think of him? "No. Not anyone that close."

"I'm sure you'll find someone, even if Kaa-san finds that someone first." Hana laughed. "Anyway, I'll do your cleaning out duty today. You shouldn't be around all those dogs. The males will feel threatened for one thing." She patted him on the head and strode out of the door with grace that Kiba could never understand. He figured she'd gotten it from their father, as well as her appearance. She was the image of their father, apparently, just like he was the image of their mother.

He picked himself up out of the tub and went to change into dry clothes. He took a quick cold shower before he did so, however, just to keep himself cool. After he had dressed again, and Akamaru had dared to come a little closer to him, he decided to take a walk and see if anyone sparked his interest.

Walking through Konoha had never been more of a task to him. He willed himself to stay calm whenever he saw a pretty girl, or more often, a pretty guy, and tried to control his raging hormones. The scent of food wafted beneath his expert nose, along with another scent that drove his hormones wild.

After a moment, Akamaru realized what the scent was and barked to Kiba, whose eyes widened. Quickly he jerked around, trying to find the source of the scent. His hormones were clouding his mind again, and it took some time to realize that it was coming from near the ramen bar just up ahead. And then he found its source.

Leaning against the wall of the ramen bar, panting heavily, clothes ruffled, hair tousled and face flushed – looking a lot like he had when he had returned to the Inuzuka district – was a familiar face. And the scent of canine was pouring out of him. Their eyes locked and both their scents mingled, becoming one scent that both of them could recognize. The scent of heat. Before Kiba could comprehend what he was doing, he was striding over to the ramen bar and was standing face-to-face with a very sexually frustrated Naruto.

And then all went blank as the animal inside of him took over.
