Two weeks into their honeymoon-

Kakashi lay stretched out on the bed next to Naru, his body aching, his breaths shallow and ragged as he tried to breathe through the strange sensations in his body. He felt overly warm, his skin sweaty. He rolled over onto his back and glanced at Naru to make sure that his tossing and turning hadn't woken her up. He needn't have worried since the girl slept like the dead.

He stared up at the ceiling and lifted his hand so that it was in front of his face and quickly counted back to how long it had been since the last time he had gone into heat.

Five months, three weeks and fourteen days. Meaning that the reason he felt so breathless and achy was because his body was preparing itself to go into heat again. He let his hand fall back to his side and groaned. This was not good. Not good at all. Naru wasn't aware of his little problem, he doubted that such an idea had ever crossed her worried mind since she had been so busy trying to get used to him and his little perversions.

In the two weeks since they had been married, Kakashi had been utterly amazed by how quickly Naru adapted to married life. She had gotten used to his presence, his sense of humor, his weird touching fetish, and truly didn't seem to mind anymore if he took things just a bit too far for her innocent mind to handle as long as he stopped when she said so.

He looked over at her again, his eyes doing a slow sweep of the naked skin of her back, the soft curve of her ass. All that creamy smooth skin that he longed to mark as his own. It had taken him up until last night to finally convince her to sleep naked next to him, and she had finally felt brave enough to try since he had taken up the habit of sleeping in sweat pants, instead of the preferred nakedness, he had gotten so accustomed too.

He was close now, he could feel it in the way that his skin tingled in some places and burned in others. His chakra was circulating in a much faster pace than normal. In the morning when Naru woke up, he will have grown wolf ears, claws and a tail.

He would recognise her scent and he'd pounce her.

He doubted that she would appreciate two hundred and sixty pounds of hard muscle jumping her and having his wicked way with her. But really, what could he do? It wasn't like he would be able to stop himself since his control over that part of his body was hanging on by a bloody frayed thread. He looked at her again.

He really wanted to wake her up and warn her but he was just so damn exhausted right now. His mind was getting fuzzy and his eyes were getting so heavy that he could barely hold them open, the exhaustion was just another way for his body to help him cope with the painful sensations of growing ears and a tail. If he was too exhausted to stay awake, he wasn't likely to feel the extra pieces of flesh tearing through his skin, or the tingle along his skull and spine he got, when they grew fur.

The last time he had gone into heat, he had managed to stay awake for a majority of the changes and had scratched a hole through his skull with his claws in an effort to make the itching from growing fur on his ears stop. Naturally it had'nt worked, and he had ended up in the hospital in a coma for his efforts.

But things would be different this time. He didn't-or rather he shouldn't need to be restrained, drugged or chased through the village and stopped from doing what his instincts demanded he should do. Hopefully he wouldn't get out of hand and accidentally hurt Naru, since she was the only female for miles that he literally burned to possess.

(****************************************************************************************************************************************************)

Naru stirred from her sleep as she heard the faintest whisper of Kyubbi's panicked sounding voice in her head.

Psst, Kit. Kit! Wake up! We have a problem!

Wha? Kyubbi? What's wrong?

No time kit. Just get up-move! Slowly! He's watching you.

Naru frowned as she opened her eyes and turned over onto her back and used her hand to grope around the spot next to her where Kakashi should have been. Kyubbi wasn't making any sense, and she was starting to feel the demon's anxiety, her body responding to it, and became anxious herself. Where was Kakashi?

Forget about where he is and just get up!

Why?

Because we're easy prey like this. Kyubbi snapped as Naru started to sit up. The demon shrieked at her to go slower. Saying something along the lines of, Any sudden moves could cause him to attack.

Who? Who might attack us? Naru asked in a trembling tone. She didn't understand what was going on. Where was Kakashi? Why wasn't he here to help her defend herself from her would be attacker?

Had he abandoned her?

Stop. Right. There. Kit. The demon hissed as she slowly reached down to grab her night shirt and froze when she felt eyes boring into her back. She held her breath as she heard a slight rustling of movement from somewhere behind her and slowly, very slowly turned her head to see who was behind her.

She saw the flickering movement of a grayish white tail as it disappeared to the other side of her. An animal? Kyubbi was freaking out because of an animal? What the hell? Was the next question she was planning to ask when the demon made a funny sound and screamed, Move!

Naru grabbed her night shirt and rolled off of the bed as something big brushed past her and hit the floor with a loud thud as she scrambled to her feet and ran over to the door and started to slip out when she decided that she should know who was attacking her, or rather what kind of animal she was dealing with and looked back. Her heart thudded in her chest as she saw the tail whip back and forth in agitation as a silver topped head peeked up over the edge of the bed.

Her heart stopped for a second as Kakashi's mis matched eyes glared at her as a low rummbling growl echoed across the room. A promise of retaliation. A warning.

Oh god, he did not look amused.

What are you waiting for kit? Run! Kyubbi yelled as she slipped out of the bedroom and closed the door as Kakashi started to move around the bed towards her on his hands and knees. He lunged at her at the last second, his long razor sharp claws catching her upper arm as she slammed the door closed and held it there as he slammed his body against it.

Clever female. She had slipped from his grasp. He lifted his clawed fingertips to his mouth and licked some of the blood that he had gotten from his prey. Another low feral sound escaping his throat. Her blood was hot, spicy, and sweet at the same time. It tasted like honey on his tongue, the scent wafting up to tease his senses.

He was going to catch her. He was an excellent hunter, and would be able to track her by scent no matter where she ran. He would have her soon. It was just a matter of time. He stood up and slammed his shoulder against the door separating him from his prey and heard her startled squeak. Ah, poor thing. She was so frightened by her close call that she hadn't moved from outside of the door.

A pity since he liked to chase his prey down, but no matter. He'd have her soon.

Naru stumbled back away from the bedroom door as she shrugged on her shirt, letting the rough cotton material fall past her hips nearly to her knees as she took several steps back from the door as Kakashi threw himself against it again.

Panic surged through her system. What the fuck was going on? She wanted to scream, this was all so frightening and confusing at the same time.

That door won't hold. Run, kit. Run now. Run as fast and as far as you can before he catches you.

Why?

Because he's in heat, and isn't in his right mind. I wish I could say that he'll be gentle with you once he catches you-The words 'And he will, catch you.' Went unsaid by the demon, but Naru didn't have to hear the damned words to understand what Kyubbi meant. But I doubt that he has that much control right now.

Is there any way to settle him down?

There is only one way, kit. And it won't be very pleasant for you. Now run. The door is giving. Naru turned and ran down the hall into the living room as there was a loud cracking sound and the bedroom door fell open. Kakashi let out the most ungodly sound. A howl to announce the begining of his hunt for her as she ran outside and slammed the door behind her and ran off into the thick under brush of the surrounding woods as he made quick work of that door too.

Using his body to break down that door too as he took off running after her at break neck speed.

Naru ducked under a branch and nearly tripped and fell when she mis calculated where a tree was, she skidded across the ground and hit it with her arm and pushed off as she changed directions and ran another way. She could hear Kakashi, tearing through the trees and bushes behind her. She looked back over her shoulder and bared her teeth, he wasn't exactly subtle. It sounded like he was knocking over a bunch of trees and such in an attempt to get them all out of his way.

Trying to make his own little short cut to her no doubt.

So the only way for him to regain a bit of his former self is to let him have me? Naru asked the demon, as she skidded to a stop and looked back. All of a sudden she couldn't hear anything. No birds. No tree's crashing to the ground. No Kakashi.

Where did he go?

Yeah, but kit...if you do this you'll be bound to him in a more permanent way.

How so?

It's hard to say. I've never really been in this situation before. Naru turned and started to run again when Kakashi jumped out of the bushes off to her left and grabbed her. Wrapping one hand around her waist and hooking another in between her legs and lifted her up off of the ground. She screamed and yelped as he slammed her body into the dirt.

Pain exploded in the back of her skull. Her ribs felt like they were crushed as the breath left her lungs and for a second or so it felt like her heart had stopped before it started up again, beating faster and harder than it had before as she blinked back tears as Kakashi gripped the front of her shirt and ripped it open.

Kit!

Naru struggled to breath as Kakashi's clawed fingertips dug into the skin of her cheeks forcing her mouth open as he leaned down and sealed his mouth over hers stealing what little precious breath she had in her lungs. She made a distressed sound and pushed at his shoulders making him lift his head and snap at her. His fangs nipping sharply at her neck, leaving a little red place as he ran his hand down the slender callum of her throat, his claws scraping against her skin making her twitch as he leaned down and rubbed his face against her neck.

First one cheek then the other, his lips brushing over her pulse point as he rubbed the top of his head against her chin. What was he doing? Naru wondered tiredly as he rubbed his face along the skin of her chest then her stomach.

He's trying to get your scent on his skin. He needs you to bear his scent as much as he needs to bear yours.

Helpful... Naru thought dryly. Now what do I do?

Nothing, kit. He's caught you. He'll take his prize and once he's himself again, you can beat him senseless.

Kakashi nipped at the tender skin of the females stomach, his fangs leaving little red bloody welts that he licked as he glanced at the females face. She was so still now, if not for the fact that she breathed he might have thought that she was dead. He ran his hands along the smooth pale skin, from neck to breast and lower making her squirm under him. His body ached, the throbbing in his cock matched the beating of his heart, his mind a blank, white haze.

He slipped one of his hands between her legs, pushing two of his clawed finger tips inside of her. She screamed and nearly came up off of the ground, her small hands grasped his shoulders and pushed, as he moved to pin her more thoroughly. His fingertips pushed through the thin barrier of skin inside of her as he settled as much of his weight as he dared on top of her, forcing her back down, the air in her lungs escaped her a second time and her teary eyes widened in fear.

He leaned his head close to her own, using his free hand to push her head back. His palm resting against her forehead as he licked the tears from her face. He had hurt her. It was'nt his intention. The fact of the matter was that he no longer remembered his intention, all he knew was what his instincts told him. He was trying to hold back. Trying to make it good for her, but it was difficult.

More difficult than he had thought it would be. He hadn't expected her to be so tight.

He withdrew his fingers and used his hand to pin her wrists as she gasped and let her eyes close, relief etched into her lovely face. Not done yet.He thought with a low growl as he settled himself between her legs, the tip of his weeping member pushing against her. Her eyes opened wide in alarm and he ruthlessly thrust himself inside of her. She screamed and fisted her hands as she arched up off of the ground, a sob slipping out of her mouth along with a low moan.

Kyuubi...it hurts...

I know. I'm working on it. Just be patient.

Naru closed her eyes and took several breaths and waited. The pain that she had felt seconds ago dulled and became a slight ache, making it easier to breath as Kakashi started thrusting his hips against her almost violently. She cried out in shock and clenched around him as each movement sent little ripples of pleasure racing through her. Suddenly it was hard to breath for an entirely different reason.

Kakashi buried his face against the crook of her neck and scraped his fangs along the sensitive skin, she gasped and twitched under him, jerking her head slightly. He nuzzled her, forcing her head to the other side so that he had access to what he wanted and sank his fangs into the tender skin forcing some of his chakra into the bloody wound as he sucked at it. Determined to leave a mark that would'nt fade.

She screamed and clenched around him, her body pulling him in deeper as she milked him.

Everything went dark for a few seconds and she went completely limp as he thrust on last time, and something warm and sticky started to fill her body. She twitched and panted, her body feeling light, and she was slightly dizzy as she blinked a few times and Kakashi's face came into view.

Now reach up and touch him and say, Good boy.

...

Do it kit, or this will only happen again if he doesn't rip out your throat first.

Naru pulled one of her hands free and reached up and touched Kakashi's face and muttered weakly. "G-Good boy, Kashi."

Before everything went dark.
