Captain Kiba Inuzuka of the elite ANBU tracking squad; Delta Dogs, walked in through the front door of his family home glad to be finished with the reports of his squad's most recent missions. He was fucking exhausted. Being the Captain sure sucked, when everyone else got to go off for RNR while you still had to do the paperwork. But that was all done now and it was time for him to get some rest and enjoy being home for a while. As he entered the house a strange new smell beckond to him and he found himself following his nose without really thinking about whether or not he should. The faint traces of the smell led him upstairs and to the outside of Kira's room. He didn't really have any right to go into her room uninvited but curiosity got the better of him and he opened the door.

The strength of the scent in Kira's room hit him like a tsunami. It was the most tantalizing scent he had ever encountered. It smelt of unrelenting passion and a desperate need to be claimed. It filled his body with desire and caused an unprecedented reaction.
He stood in her doorway in shock as his erection throbbed painfully. What the fuck was this? A whole new level of loss of control to her scent? Why hadn't he recognised it as her scent straight away, and why did it smell so much more alluring with a hint of desire and arousal. The logical side of him reminded him that he still wasn't certain she wasn't a spy and therefore not a threat to his village, his family, and his pack. Yet his instinctual side didn't give a shit about any of that. It was screaming at him to fuck her right now. His hands became clawed as they dug into the sides of his pants tearing the fabric. His breath came in heavy pants as he was flooded by overwhelming urges and every muscle fibre in him trembled as he tried to ignore the beast inside him. It wanted him to hunt Kira down and to claim her as his own.

Kiba began to become vaguely aware that Hana was standing beside him trying to talk to him but he couldn't focus on her words when his ears were pounding with the flow of his blood and he felt like his body was going crazy with the need to have Kira in his arms, under his body, calling his name.

"Mum can you come here please!" Tsume heard Hana shouting "Kiba's acting really fucking weird!" Tsume went rushing up the stairs. What was Kiba doing home? Had Hana's message not got to his office. Tsume approached Kiba in full Alpha mode ready to deal with the situation but she faltered for a moment when she saw the state her son was in. She had never seen anyone have such a strong reaction to another's heat. She was concerned for her son, however at this moment she was more concerned that Kira may be in her room with Kiba about to jump her. "Stand down Kiba" she commanded with all of her pack authority. The look she received stopped her dead in her tracks. Kiba glared at her like he would kill her if she got in his way. But it wasn't anger that she saw in his eyes it was the power and dominance of an Alpha. "Holy crap that look" said Hana shrinking away from Kiba. As a Beta she was more affected by the Alpha vibes currently emanating from him. Tsume on the other hand was still this packs lead Alpha and she would remain so until challenged. Now was not the time for any of that however. Kiba was clearly going wild with need, and this situation would require a more human approach: a mother's love and understanding. "Kiba? Come sit outside son, you'll feel better if you get some fresh air". She tried tentatively. It worked, Kiba sighed deeply, nodding his head and made his way outside.

Kiba breathed in deeply trying to get as much fresh air in his lungs as possible. Tsume passed him a glass of water and instead of drinking it he threw it in his face.
"You feeling any better?" Tsume asked.
"Fuck!" was the only word he could manage.
"So you and Kira huh?" Tsume smiled all-knowingly.
He breathed deeply a few more times then responded.
"There is no me and...her" he found the process of saying her name to be a little troublesome right now.
"Really?" Tsume raised a brow "What was that all about then?"
"I don't know" He said grabbing the jug of water she was holding and gulpping it all down.
"I think you do"
"Get off my case Ma. It just...happened, ok."
"And why do you think it happened?"
"I don't know"
"Come on Kiba. Do I have to spell it out for you? You're very clearly attracted to her."
"You adopted her!" he retorted angrily "Isn't she suppose to be like my sister now." He really shouldn't be thinking of her that way. Should he?
"You don't need worry about that. No-one would question it. At least not within the clan but who cares what outsiders think. They could never understand such a connection. If you are meant to be then that is far more important." she paused for a moment thinking of her own bond with Hana and Kiba's father, she missed him dearly. "Kiba" she continued "you must know that in the Inuzuka clan nothing comes above the bond of mates."

"We're not mates and we're not bonded!" Kiba exclaimed. This was getting annoying.
"Well I can see that your not bonded" Tsume retorted her own anger rising. "If you were you would be off fixing the sorry state that your Omega is in not arguing with me about the obvious fact that you two are mates."
"What do you mean?" Kiba asked "What state. What had happened to her?"
"She's in heat. Obviously. You can't be this clueless, pup."
In heat? So that was why her scent had been so different? Wait why hadn't anyone warned him. "A heads up about that would've been nice." he said accusingly. Tsume was really getting over this attitude. "Hana sent a message to your office asking you to stay at a friend's place for a couple of days but we weren't exactly going to state why."
"I didn't received it" Kiba said looking shamefaced.
"Then you might want to yell at your Junior for it never getting there. Not me! Besides that message was sent for Kira's comfort. The poor girls embarrassed by her first heat. We didn't know you were the one that set it off."
"What to do you I mean I set it off? I can't have. I'm not her mate." he stated determined to be right despite all evidence that he was wrong.
"Actually you being her mate is the only logical explanation." Hana intervened. He hadn't noticed when she had joined them but he was sure she was there to play peacemaker in their argument. Betas were annoyingly good at that.
"When you carried her back from your last mission" Hana continued "it must've been her first time in close proximity to you, and your scent. From this her body identified you as her mate, released certain hormones and that triggered her first heat." Hana explained in her scienctific way.
"How can you be so sure that it was me and not someone else she came in contact with?"
Of course it would be awful for the girl if it had been one of those enemy nin but he had to ask.
"Because only a female's mate physically responds to her heat." Hana stated matter of factly.
"Are you sure?" Kiba really hoped there would be even a small percentage of doubt. He just didn't think that he was ready for this.
"I am an Inuzuka biologist and veterinary scientist. Understanding Inuzuka Instinctuology is a part of my role." Hana explained feeling just a little annoyed that she had to do so.
Kiba stared at her blankly.
"Yes. Im sure." she stated.
The truth finally dawned on him. They were right, if he stopped to consider the facts. It was completely obvious. He had to be her mate. That meant that this girl, she was his soul mate.

"She could still be a spy" Kiba argued.
"Oh for goodness sake Kiba!" Tsume exclaimed. "How many times do I have to tell you? My instincts led me to her and I could feel it within my heart that she was of Inuzuka blood. She belongs here as a part of the Inuzuka clan. Why do you continue to question my instincts, and for that matter why do you continue to question your own?" He looked at her puzzled. "Kiba," Tsume sighed resolutely "I have never seen anyone react to another's heat like that. I can only guess that your reaction was so strong because you already knew that she was your mate and you have been rejecting your instincts".

"All my instincts have been doing is driving me into a sex mad frenzy. What use is that?" Kiba complained.
"No you drove yourself to this point by trying to deny what your instincts know to be true. Surely there have been hints before now. Perhaps liking her scent, an increased sensitivity to contact with her, or a hightened awareness of her presence? I can understand Kira not noticing such things but as a born and raised Inuzuka you should know their meaning."

Hints? More like sirens. He wasnt just taking about her heat, he had been sex mad for her from the first moment that he had encountered her.

"Ok so maybe there were...signs. But I didnt think that she could possibly be my mate"
"So you've been ignoring the Inuzuka instinctual talk, as one might call it, and now your body is screaming at you to catch on"
"How can I take her as my mate when I dont trust her."
"I dont know how to convince you to trust her, me, or even yourself. I guess thats something your just going to have to work out on your own." Tsume went to leave but then she thought of something. Turning back to face Kiba as she said "One more thing. How many women have you slept with since meeting her?"
"I dont know, I dont keep track" Kiba lied.
"Ha dont lie to me, pup. The answer is, not one. Thats not like you is it? You usually have sex at least once a week."
"What the hell Ma?!"
"You didn't seriously think I was clueless did you? I could always smell it on you when you came home." Kiba groaned there was just no privacy in the Inuzuka clan. "Just something to think about." Tsume said casually, sauntering off.

"I need a beer." Kiba decided then. Leaving in a puff of smoke.
