Authors Note: I don't own Haikyu or its characters.

I didn't expect this story to turn out as long as it has. The dream didn't seem that long, but it was good. Sorry for the slight OOC, I hope I can get them back towards the originals after this chapter. The dream was in different segments so I am trying to piece them all together. This chapter bounces around more than the previous one did. I also wrote this over time and not as a one shot like the last chapter. As I said before, I'm not a writer so this is my first attempt at writing yaoi, please forgive me if it sucks.


It's needless to say that their parents weren't exactly happy when they came into the room, but it was now clear there was no blame to be put on either Kageyama or Hinata. Fate mates aren't able to resist each other during times of heat or rut. The next few hours were just plain annoying. Filling out paperwork to register as fate mates kept both the boys and parents busy. Kageyama didn't even see why they wanted to know what his favorite color or food was but, the sooner it was over the better. Hinata was unusually quiet through the whole thing, mostly holding his hand over his fate mark as if he still couldn't believe it. Kageyama could feel a sort of contentment coming from Hinata, probably happy at the thought he wasn't crazy for wanting Kageyama as a mate. Truth be told they had absolutely hated each other in the beginning. His original opinion of Hinata had been he was a waste of perfectly good space, just a ball of energy that didn't know the first thing about volleyball.

Kageyama smirked, boy had everything done a 180, especially after last night. However, Kageyama's patience was starting to wear thin. Not only had they missed practice this morning, they would be missing this afternoon as well and about three fourths of the way through the paperwork they were informed that tomorrow they would be required to meet with a specialist and miss yet another day of practice. They had both voiced their displeasure at that, but were happy that neither set of parents would be present for the whole thing tomorrow. They would meet the specialist at the Kageyama household around lunch time. Apparently Dr. Machigawa had phoned the specialist immediately after he had spoken with their parents. The specialist, a Dr. Ryugazaki, would be flying down from Hokkaido. He was Japan's foremost expert on fate mates and quite renowned in other countries as well apparently.

It mattered little to Hinata or Kageyama as long as it didn't take long. When everything was said and done the whole group went out for an early dinner. It had been slightly awkward at first. Neither set of parent quite knew what to say in the beginning. After initial greetings the food arrived and things seemed to relax. Food always does wonders for the mood, especially okonomiyaki. Kageyama and Hinata dug right in and chatted and argued about volleyball as per usual. Kageyama still called Hinata a dumbass though he'd heard a rather sharp word from Hinata's mother about watching the insults around Natsu. Natsu was content just sitting next to her brother, scooping bits of his food when she thought he wasn't paying attention.

Their parents had expected a big fuss when it came time to leave, but were in for a surprise when Kageyama and Hinata had parted ways quite amicably without even a hint of a fuss.


Kageyama yawned as he lay on his bed tossing his volleyball up in the air. His parents had already left for work and he was dressed for the day, just waiting on Hinata to show up. They were supposed to meet that specialist around noon but he had texted Hinata as soon as he woke up and told him to head over early so they could get in some volleyball practice before they were forced inside for however long this meeting was supposed to take place. Hinata had responded almost immediately saying he was already out the door and on his way. Kageyama sighed. Neither he nor Hinata were sure on how they were supposed to act around each other. I mean, yes they were mated now and all, but it seemed that neither of them really wanted anything to change. They had both been happy with the way things had been before they had mated.

Mating just seemed to tie them even closer to each other than they were before. They both thought of each other the same way as they did before. Aside from the heat of that first night, there hadn't even been a change in Kageyama's sexual attraction towards Hinata. He still wanted to lay his hands all over the small orange haired boy, the only difference was, now he probably could do it anytime he wanted. But he wasn't sure how Hinata would react to that. Hell he wasn't even sure he knew how to react to that. Wanting to initiate that kind of intimacy without heat or rut as the driving cause was something they would definitely need to work out. Come to think of it Dr. Machigawa had said something about fate mates having special rules when it came to such things like heat and rut, but hadn't gone in to detail about it. Perhaps the specialist would be able to tell them more about it. Whatever the case, they would deal with it, as long as they could continue to play volleyball.

The doorbell rang and Kageyama righted himself before he headed off to the door to let Hinata in. Kageyama definitely hadn't expected to deal with it so soon. Almost as soon as he opened the door and laid eyes on Hinata he felt that same absolute awe he had two days ago, how absolutely beautiful (and fuckable) his mate was standing in front of him.

Hinata had stiffened for a moment when the door opened almost expecting it to be Kageyama's mom or dad but relaxed when Kageyama's familiar face came into view. But as soon as their eyes had met he felt his body heat up, fast. The heat pooled in his gut and unable to stop himself Hinata moved forward. Their lips met in mutual need and desire hungry for one another in a way they hadn't quite felt last time. When they pulled back breathing heavily, Kageyama grabbed Hinata by the wrist and pulled him inside letting the door swing close by itself. As soon as Hinata slid his shoes off Kageyama had him pressed against the wall, their tongues sliding together.

Kageyama's hand trailed up underneath Hinata's shirt. Hinata squirmed slightly at the touch, heat and slick pooling in his lower regions. It wasn't long before the shirt came off entirely. Kageyama could smell the slick, his own body hardening in anticipation.

They ended up in Kageyama's bedroom, a trail of clothes behind them, neither bothering to care, nor notice that the door hadn't quite latched properly. By the time they hit the bed there was nothing left between them, only skin as the kisses continued and heated up even further.

Kageyama sat down on the bed pulling Hinata up over him. When Hinata's weight suddenly shifted forward losing his balance Kageyama fell back Hinata following. When Kageyama made the move to roll them over Hinata resisted. Unhappy, Kageyama tried again a little more forcefully but Hinata would not roll. Kageyama broke the kiss inhaling a large breath ready to berate Hinata but didn't get the chance.

"I want to ride you," Hinata breathed in Kageyama's ear, finally giving voice to the thoughts swimming in his head and the reason for his continued resistance.

Kageyama hesitated, as the Alpha he wanted to be in control however deep inside he knew it was his duty to please and take care of his mate. Feeling Hinata's desire and desperation through their bond, Kageyama nodded. Hinata wasn't being stubborn or vying for control, he needed this. Omegas after all were just as possessive of their mates as alphas were only in a slightly different way. Somewhere inside Hinata needed confirmation that Kageyama was his and only his and that they were partners.

Hinata ground his hips down against Kageyama again in impatience. Kageyama moaned, all thoughts flying from his head. Hinata wanted to service him, to pleasure him and the offer was the most tempting thing he had ever come across aside from anything volleyball related. The smell of slick only adding to the lust he felt rise up in him.

"Let me stretch you first." Hinata bit his lip and made a move to get off of Kageyama but firm hands on his hips stopped him.

"Wha…" Hinata looked up at Kageyama in confusion.

"Just move up a bit." Kageyama said guiding Hinata forward until Hinata's erection was right in his face. Now straddling his mates chest Hinata looked about to protest in embarrassment when Kageyama leaned forward and took Hinata completely in his mouth. All rational thought flew from Hinata's head as pleasure invaded every corner of his being only to double when Kageyama slipped a slicked finger inside him.

One finger quickly became two and then three as Kageyama wiggled them about. When Kageyama brushed up against something hard inside, the moan he received was so erotic he felt himself twitch in expectation.

"Tobi… oo…" Hinata called out in pleasure and frustration. He couldn't take it anymore.

"Please…" Hinata begged Kageyama, wanting… no needing things to go faster. Unable to wait any longer Hinata grabbed Kageyama's wrist and removed the fingers that had been stretching him so gently. He pulled back away from the tight moist heat of Kageyama's mouth and moved down for a passionate kiss. Wanting things to go faster as well Kageyama didn't protest the action. When the pulled back for air Hinata sat up on his knees. Hinata's hand snaked down grabbing hold of Kageyama's stiff erection aligning it with his entrance and without further warning, impaled himself upon it.

"Ah…" They both moaned in ecstasy, lost in their own world. Hinata cringed a little at the stinging he felt. Perhaps it hadn't been a good idea to just drop down like that. But even with the slight pain there was such immense pleasure at the feeling of being filled completely by Kageyama. Hinata took a breath and lifted his hips back up only do drop back down harshly, letting gravity to most of the work. He picked up the pace, moving up and down much faster. Neither of them was going to last long today.


Dr. Ryugazaki sighed as he checked the address again one last time. He was definitely in the right spot however he wasn't exactly sure what he should do in the current situation. He was about an hour early to the apartment to meet the new fated couple. It was normal to meet a couple in their apartment, usually it kept them much more relaxed and open when discussions hit awkward points. But this had to be a first for him in all the years he had studied fate mates. Ryugazaki had knocked only for the door to open and the smell of heat to hit him dead on in the face. There was no doubt about what those two were doing at this very moment. He sighed again. If they were going at it at this time of day then there's no telling what it was that had set them off. On top of that he was told he was dealing with minors, also another first in the world of fate mates. The youngest fate mates in the world had been 47 years old, remarkably young if you considered their life span of 400 plus years. Fate mates at 16 years old. Oh boy would the press eat this up once it was announced.

Dr. Ryugazaki pushed his glasses up the bridge of his nose in thought. So much had been learned from that young fate mate couple, perhaps they would come closer to unraveling the mystery that was fate mates. He took another breath then cleared his throat. But first they were going to have to find out what the trigger was for this pair and how they would work around it, what with school and club activities and all. If they boys were lucky it would simply be on a time cycle and could plan for it. If they weren't lucky it could be anything. Almost all the fate mate couples in Japan had a different trigger that would set off heat and or rut respectively.

Deciding it would be best to just wait it out, Ryugazaki closed the door and latched it properly. He opened his bag and took out a folder of copies of the paperwork the boys and their parents had filled out just the day before. He concentrated on reading through them and committing what he could to memory, also studying a picture of their fate mark. Perhaps starting with some talk on volleyball would be a good way to kick things off and break the ice. It would only be about an hour before things settled down in the apartment. Then he would knock again, blatantly ignoring the smell of heat and sex in the air, already knowing to expect it.


Kageyama nuzzled Hinata's orange hair in contentment as they lay waiting for his knot to go down. Though it hadn't been quite as intense as their first night they were both completely satisfied. Their breathing had somewhat calmed down but their emotions hadn't quite settled. Almost as soon as they had finished coming they both felt that strange connection again. Their minds had connected in much the same way as it had the night before, though now they knew a little bit more about how to use the connection. They had moved right into viewing each other's most recent thoughts and memories of all that had happened over the last day and a half.

Kageyama wondered if this would happen every time they would mate, not that he hated it in any way. But neither of them were sure what it was that set off this latest session of mating. They had simply locked eyes and the next thing they knew they were headed towards the bedroom. Kageyama sighed as he looked at the clock. It wouldn't be too much longer before that specialist got to the apartment and they really needed to clean up before that guy got there. Hinata glanced up at Kageyama and smiled at him. He was enjoying this. They both were. But he could see in the back of Hinata's mind the worry he had wanted to keep hidden. Worry about how they would deal with the sudden changes in their relationship, how it would affect their volleyball. Kageyama shared much of the same worries. He didn't exactly want their relationship to change too much. He had been happy with how they treated each other before. And what were they supposed to do if Hinata went into heat so suddenly again or he went into rut in a not so private setting.

"I guess it's time huh?" Hinata asked laying his head back down, ignoring the thoughts circling around in Kageyama's head. They would just have to take it one step at a time. He felt Kageyama sigh again underneath him and sadness at having to disconnect from each other so soon. That was what troubled Hinata so much. He had spent so much time working hard, training, studying, to be independent, yet here he was, reluctant to pull away from a connection that frightened him to his core. It wasn't like he had anything to hide from Kageyama, but sharing his every thought was a little troubling. Though Hinata tended to voice most of his thoughts out loud, there were somethings he chose to keep to himself, he didn't want Kageyama worrying over his own stupid fears and worries. It was plain that Kageyama had enough on his mind as it was.

"Yeah." Kageyama finally answered. "We need to get things cleaned up." Hinata nodded and moved to get up. When their bodies disconnected so did that strange connection. They both felt relief at that. Hinata went straight to the bathroom to wash up as Kageyama walked through the apartment and gathered up the clothes that had been strewn about on their way to the bedroom. He placed them in the dirty clothes hamper and grabbed a set of clean ones for each of them. His clothes would be large on Hinata but they would work for the time being. Kageyama smirked at the idea of seeing Hinata all dressed up in his clothes, satisfaction swelling in his chest. For good measure he rubbed a bit of his sent into the clothes.

He opened up the window in his room to let in some fresh air and get rid of the smell. It wouldn't completely dissipate but it would at least make it less potent. Kageyama headed to the bathroom and cleaned up as well. It didn't take them more than 15 minutes to be clean and changed. They ended up opening the windows in the kitchen and living room also, hoping to air things out as much as possible. They had been just about to settle down on the couch when they heard a loud knock on the door.

Kageyama went to answer the door and let the man in. He looked middle aged with short black hair and red rimmed glasses. He greeted the young alpha pleasantly and followed as Kageyama lead to the living room. After the normal niceties and exchanged greetings there was a moment of awkward silence as the boys sat and waited for a storm of more questions like the ones they had answered the other day. Really they just wanted to get this over with as fast as possible and get outside to do some training. They hadn't expected Dr. Ryugazaki to ask about volleyball or that they would spend over an hour talking about it. They talked about various well known pro players and then talked more enthusiastically about their own team and the upcoming spring competition. They also talked about being invited out to Tokyo by Nekoma to participate in practice matches there and the dreaded tests they were struggling to deal with.

To Dr. Ryugazaki they sounded like normal teenage boys enjoying club activities. There wasn't that overly lovey dovey feel that most new fate mate couples gave off, being completely infatuated with each other. They boys sat next to each other but didn't cling yet another sign of their youth. He smiled at the passion he could see in both boys as they talked about volleyball. Even the omega had a lot to say, interrupting Kageyama quite a bit. Hinata was what he would classify as a bubbly personality. After the boys seemed to be quite relaxed and talkative Dr. Ryugazaki switched gears on them and moved the topic away from volleyball.

"You haven't practiced since you mated have you?" Dr. Ryugazaki asked knowing they hadn't really had the time.

"No…" both of them said in unison. They glanced at each other with a slight blush and then looked back at the doctor.

"We haven't had time yet." Kageyama stated. "Why?"

"I was wondering how you two would decide to deal with your bond and mental connection while you play." Dr. Ryugazaki pushed his glasses up watching the boy's reactions.

"Well mostly we just plan to ignore it while we play." Hinata said a little unsurely. To be honest they weren't sure how their recent mating would affect their play. It was something they both wanted to figure out quickly. They couldn't afford for things to be too affected.

"Though it's only been a day or so, do you have any ideas about what triggers your heat or rut yet?" Kageyama blushed as did Hinata at the question.

"No, the doctor the other day said that fate mates have special rules with it comes to mating, is that what you mean?" Kageyama asked, keenly interested. If something a triggered them this afternoon maybe they could figure out what it was and avoid it when they needed to.

"Well yes. Typically each fate mate couple has a different trigger. Some are on a time schedule, which seems to be the most common. The shortest I've seen is 24 hours. The longest has been a week, it's really tough to deal with if you're apart at the time. A few couples deal with distance as an issue, the second most common, if they go a certain distance or further away from each, they immediately go into heat or rut respectively upon being reunited. Other less common triggers are certain scents, certain foods, and one couple where there mates wearing a certain color was the trigger. Took them quite a while to figure that one out." Dr. Ryugazaki explained. "You two will also have a trigger of some sort. It can trigger you both or it can trigger one of you. With your bond and mental connections, if one of you is triggered the other will follow right after usually. Since you're the youngest fate mates there has ever been I am guessing your connections are strong. In general the younger the mates are in this situation the stronger their connections will be."

Kageyama and Hinata took this all in. So they would have to figure out what their trigger was and from what they could tell it could be almost anything. Where the heck were they supposed to start?

"The best way to narrow it down will be to keep track of everything when you get triggered. Make a note of the time, date, what you're wearing, how long you've been apart, of far you've been apart, what you've eaten, what you smell, the sounds you hear, everything."

"How the heck are we supposed to do that?" Hinata exclaimed. "I can't even remember half of that, and when I go into heat I won't remember any of it." He blushed, "my mind gets wiped of everything as soon as Kageyama touches me when I'm in heat. Kageyama tried his best not to blush. He really wanted to elbow Hinata in the ribs right now for spitting out something so embarrassing, that dumbass. But he understood that Dr. Ryugazaki was there to help them figure all this out.

"I don't think it's time related" Kageyama said. "Err… well at least not on a time schedule."

Curious, Dr. Ryugazaki asked, "Why do you say that?"

Kageyama replied quite surely, "Well from what you said, if it was a time schedule we would go into heat or rut even without our mate there, right?"

"Well, yes that's true."

"This afternoon when Hinata got here, as soon as we saw each other he went into heat and almost simultaneously I went into rut."

Dr. Ryugazaki looked highly interested at this new bit of information writing it down on his notepad in front of him. "You're probably right, that sounds more distance based but there could be more to it. How long were you two apart last night?"

Kageyama couldn't remember at what time they had left each other after dinner but he did know he fell asleep around 10 that evening and Hinata had made it over to his hour sometime around 10 so it was at least 12 hours. He was surprised when Hinata answered instead of him.

"We left each other around seven last night so I think about 14 or 15 hours."

"How far away do you live?" He asked Hinata.

"Err… I don't know the exact distance. I live just over the mountain. It takes like 45 minutes to get to school on my bike." Hinata said, and then stated he would have to look it up online to find out the exact distance.

Dr. Ryugazaki nodded. Their trigger sounded more like it was distance based than anything but he didn't want to rule anything else out. "It would be best if you keep a record of how long and far you are apart, but that doesn't mean your trigger is distance based. You should also write down anything you can remember about the other when things start heating up. Clothes, smells, and such." Kageyama nodded, this sounded a lot more complicated than he thought it would be. But he was sure that once they figured it out, things would relatively go back to normal. "That's about all the advice I can give you on the subject. Normally I would advise couples to take a week or so off work until they have a better idea of what sets them off. But you two can't really do that with school or with club activities." Dr. Ryugazaki sighed. This was going to be tough with minors.

"So… what do we do if this happens at school?" Hinata asked.

"I'm glad you asked, that brings up something else I want to discuss with you. First off, you two haven't fully been registered as fate mates." Surprised they asked what in the world the paperwork had been for if not to take care of that and what that had to do with the question Hinata had asked. "Most of the paperwork was for registering, the rest of it was for my records, but I asked Dr. Machigawa to hold off on putting the paperwork through. The thing is, once your paperwork goes through the system Japan will announce that another fated couple has been found, there will be cameras and reporters swarming everywhere around you after that happens."

Kageyama frowned not liking the sound of that, they would just get in the way of practice. "I want to hold that off for as long as possible. I am going to meet with a few members of the upper house and see if there is any way we can wait to report things until you turn 20. As such I don't think it's a good idea for too many people at your school to know about the fact that you two are fate mates."

"So then… wha…"

"Yes it is likely that you will go into heat or rut at school until you can get a firm grasp of what your trigger is. But only a few people should know you're fate mates. So I think talking to one teacher about this and getting you two a private space to take care of things would be best. Do you have a teacher or an adult at the school that you can speak to about this? Someone you both like and trust, perhaps your coach or club advisor?"

"We can talk to Takeda-sensei about it." Hinata suggested thinking very loudly towards Kageyama that he definitely didn't want to be the one to say something. It was going to be way too embarrassing for either of them. Kageyama nodded at Hinata and assured him through their thoughts that they would suffer through it together. Dr. Ryugazaki noted the silent exchange but didn't say anything, only making a note on his notepad.

"With that decided, you can cover your fate marks quite easily. However, you won't be able to hid the fact that your mates. Everyone will be able to tell just by your scents, so be prepared to deal with a lot of… adverse reactions. Some even worse than your parents initial reactions."

"What about the team?" Hinata voiced one of the worries that had been bothering Kageyama quite a bit. "We can't exactly hide something like this from them, they need to know that this is going to affect the team and the way we play. Besides teamwork is about trusting each other." Hinata declared very sure that the team and coach should know.

Dr. Ryugazaki considered this carefully. As their fate marks were volleyballs there was no way they would agree to remove themselves from the team and no way they would quit playing the game. Volleyball was so much a part of these two that there was an indelible mark on their skin to prove it to the world. He sighed, so complicated. "If you have to tell them it would be best to do it one by one. Start with the upper classman and then work your way down. Save the ones you think will be troublesome till last when most of the team already knows they are less likely to make things difficult for you. But make sure you are clear that they aren't to tell anyone. Your fellow first years aren't likely to understand much about fate mates as you haven't had that class yet. It would be best if you had Takeda-sensei or your coach present at the time you do this."

"I think it's best that we end things here. You should speak with Takeda-sensei today if possible. You want to have things set up before you head back to your school and club activities. I have more questions and information for you but it can wait until you have things more settled and figured out." At that, Dr. Ryugazaki packed up his file and notepad and bid the young couple a good evening.
