A/N: The universe of Alpha/Beta/Omega Dynamics seem to be a LOT of fun, so I wanted to try it with KuroBasu fandom. Usually, the Dynamics work on an alternate universe in which Werewolves are merged into human society. But in this AU, I think it suits better to adopt the Universe of Madararui from the manga Sex Pistols, which makes this fic a cross-over. If you haven't read it, it's basically Alpha/Beta/Omega with slightly different dynamics, instead it is Heavy/Middle/Light Seeds, which theoretically mirrors similar rules. Except they're less about packs and/or dom-sub relationship between the higher and lower classes and a degree more civilised (although still leaning to their animal instincts such as scenting), and has no means to 'infecting' others as they were born as they are (they are humans who evolved from animals that aren't primates and able to shape shift into animal forms). They are also in fact, has more variety in the species categorisation. Such as werecats, weredogs, werereptiles, etc. I won't closely adopt the Madararui universe from a to z, however. For more information, I suggest reading the manga.

Weremanity Glossary

Heavy Seed/Alpha: Werepeople whose 'true forms' are animals at the top of the food chain pyramid, mostly big carnivorous animals such as Leopard, Grizzly Bears, Wolves, Boas, etc. Possessing very strong pheromones and even capable of supernatural powers, but has low birth/fertility rate. Their numbers are few, but greatly admired by the rest of the weremanity as the alphas. Their status and wealth are those of the rich and famous. Two Heavy Seeds may mate, but the chances of producing children are slim, thus they are recommended to mate outside of their class.

Middle Seed/Beta: Werepeople whose 'true forms' are animals on the middle grounds of the pyramid, consisting of mostly big herbivores and smaller carnivores, such as middle-sized dogs, wild cats, etc. They are below Heavy Seed in strength and has no supernatural powers. They are, often mated to Heavy Seeds for their average fertility rate, should they wish to breed more Heavy Seeds, though it has higher chances of producing Middle Seeds. A lot of the Middle Seeds families are wealthy, although not as much and never as powerful as the Heavy Seeds.

Light Seed/Omega: the "Average Joes" of the society, Light Seeds' true forms are animals belonging to the bottom levels of the food chain, sometimes of the domesticated variety. Light Seeds neither possess strength or wealth as the classes above them, but compensated by having high fertility rate, even with the males. They are often underestimated, but their numbers cover most of the werepeople population - save for the primates. Dogs are known as the most common variety of Light Seeds.

Primates: the normal "humans" evolved from primates, who cannot shape shift into their animal forms. They are also unable to acknowledge the rest of the weremanity species as the Primates are self-absorbed and ignorant, the principles of "don't see, don't hear, don't speak" are encoded into their genes, thus they deliberately ignore all things concerning the other species even if it's thrown to their faces. They possess the largest number in the weremanity population (up to 70%) with high level of fertility. The other species envy this advantage, but refrain from associating with the Primates, especially when it comes to mating, as children from such reunions almost always result in Primates.

Parasites: These are non-lethal parasites used to create temporary womb within male bodies in order to procreate by inserting it in the anus. High-quality parasites are expensive and hard to come by, often exclusive to Middle and Heavy Seeds. This invention was created through hard labour to compensate the werepeople's dwindling birth rates and fertility, thus homosexuality and promiscuity in general are acceptable among the werepeople so long as they continue to procreate. Incest is, however, forbidden.

Chapter 1: Late Bloomer

—

In Basketball, things like Heavy Seeds, Middle Seeds or Light Seeds classes did not matter.

Kuroko might never be as powerful and swift as a panther like Aomine, as versatile and witty as a wolf like Kise, or as devoted to incredible precision as a cheetah like Midorima. He did not have the natural freak mutation of a grizzly like Murasakibara, or a lion's charismatic superiority like Akashi. But Kuroko, a Light Seed among these purebred Heavy Seeds, an Omega in a pack of Alphas, was the one they all came to respect, despite his meagre talent, low physical abilities and lack of presence.

His Basketball knew no boundaries of the Seeds classes, and he was proud of it.

To be a shadow; the supporting character in the sidelines who would never be the star actor, would never have the spotlight trained on him. Yet he was the one person who could change the tone of the game in mere minutes. He made use of what little his animal advantages could give him, obsessively tuned his Misdirection and passes, and led them to victory. He, a Light Seed. Weak, small and underestimated as he was, the bottom of the pyramid, Kuroko Tetsuya was Teikou's Generation of Miracles' Phantom Sixth Man.

And yet even that, paled in comparison before those Heavy Seeds' monstrous talents.

The more they grew their natural abilities, the less they believed in Kuroko's. In the end, they hardly needed him to win the games. After Aomine's skills bloomed; the Panther in him blossomed to full-fledged predatory on the court and Kise's wit and physical abilities developed beyond that of Kuroko's, then the rest follows. They didn't need a Light Seed's tricks, not anymore. The differences between their natural advantages as Heavy Seeds and his own limited Light Seeds' potentials were too great.

Much like his presence, Kuroko faded into obscurity once again.

In his need to prove himself — his Basketball, he enrolled to Seirin.

He met another Basketball-obsessed Heavy Seed with freak potentials who disturbingly reminded him of the old Aomine — the one who was his best friend, not the wild predator he became. A Heavy Seed Tiger, he observed. Yet … Kagami Taiga was different. The moment he saw Kagami, he emitted a strong, masculine scent made too obvious by the sweat on his back as he played the ball. Kuroko's nostrils had flared instantaneously.

His mind screamed. His skin pricked from the insides and he felt his blood boiled beneath a layer of thin, pale skin. The way Kagami smelled was infinitely different than the way Aomine did — as he should, they were different people despite being in the same feline family — but something about Kagami's stirred a wild sort of cyclone of emotions within him that Kuroko did not expect to be capable of. He was able to maintain a calm facade as he had trained to do so in order to maximise his Misdirection, but he could not understand nor explain why exactly he felt that way.

He later thought, it might be because he felt Kagami had the potential to beat the Generation of Miracles — maybe it was his instincts alarmed by Kagami's natural talents.

Time skipped, despite their failure in the Interhigh preliminaries — he was proven right; Kagami and the Seirin team were able to defeat every GoM challenge presented to them and they won the Winter Cup, despite all odds. Kuroko's own Basketball was proven and had blossomed beyond everyone's expectations. His Misdirection had suffered along the way, but Kuroko was confident he could come up with another strategy to remedy it.

After the Winter Cup, however, there was one aspect that had changed.

It was December and everyone in school was having their Winter break, except the Seirin Basketball Club, who could hardly catch a break with a coach like Riko. They still had to come to school for practice five times a week — despite having just won the Winter Cup — which was more than enough incentive for the female student coach to get fired up with even crazier training menus.

One day, it had gone as usual by the end of a day's training — Kuroko having vomited twice and promptly passed out on the floor halfway through the training — he, Kagami and the rest of the First Years were the last to stay because they were tasked with cleaning up. The Second Years seniors had gone to the showers, some had left early, bidding them goodbye. Furihata, Kawahara and Fukuda were in charge of sweeping the sweat and dirt off the floor, while Kagami and Kuroko were in charge of taking the balls and equipments back to the storage.

It started when Kagami and Kuroko entered the storage pushing the ball cart. The immediate smell of dusts and unpleasantness filling the tiny space attacked Kuroko's nostrils. He was busy coughing and rubbing his eyes that he missed the strange look Kagami shot him, nor did he see the flash of wildness that stayed in those red eyes.

"Kuroko…"

Tetsuya had heard him stutter in uncertainty. Kuroko made a noncommittal sound, of "hmm?"

A gulp.

"You… you smelled."

Kuroko's hands stilled. He shot Kagami a look of mild annoyance.

"Why thank you, for stating the obvious, Kagami-kun. We did just finish up a day's worth of training after all. I am very much soaked in sweat at the moment. I am aware that sweat does, in fact, have a smell." He said in dismissal, then decided to ignore Kagami and finish up soon so he could get a vanilla shake for dinner.

"No, dammit. It's - it's different!" Kagami sounded frustrated. It was strange, given the meagre circumstances. Kuroko turned to give him a questioning look. He cocked an eyebrow up when he saw a flush gracing the tiger's face.

The Heavy Seed's mouth seemed to run at a speed that Kuroko could barely comprehend.

"You smelled! You do realise — as much as I think it's fucking freaky and abnormal but I thought maybe it's because of your special ability and all with what the weak presence and your way of doing basketball. And I didn't ask 'coz it's useful in the court, even though it bothers me — but the point is — you didn't actually have a scent before!" Kagami ran a hand over his hair, eyes darting away. Still flushed. He started to radiate a heat kind of scent that jerked Kuroko's attention.

But he somehow managed to redirect Kagami's own scent in favour of curiosity of what he just said.

"What do you mean by me having, and not having a scent?" He cocked his head to one side, still didn't understand the implication.

No reply.

No explanation came up. Or even a sound from the other man.

"Kagami-kun? Are you alright?"

Kagami's flush seemed to worsen. Kuroko almost thought he might have caught a cold — even though they said idiots didn't catch colds — he felt worry began to rise up his guts as Kagami radiated heat like a furnace. He resisted the sudden urge to seek comfy warmth against a sick person even if it was so cold around this time of the year, maybe Riko's demonic training had finally wore him down?

Decided it was best to examine his teammate's condition first, Kuroko took two steps forward and pressed a pale palm against Kagami's forehead. Whoa, he did feel like a furnace, he was burning! Kagami stiffened at the touch. When Kuroko was about to mention this, his senses were suddenly overwhelmed by Kagami's scents. The thick scent crept up his nostrils and he didn't know how it had inexplicably rose a reaction out of him. A strange sort of reaction. A heady swirl within his tummy. His mind seemed to drift off slightly.

It grew stronger with the close proximity. But it was… not unpleasant.

Kuroko began to lean a bit into the scent, he felt a comfortable lull about it, attractive… and strange. A giddying kind of strange. He breathed in the scent deeply, closing his eyes. A second later, he heard a hitch of breath drawn sharply from above him and he was suddenly shoved away by the shoulders. His eyes flared open in confusion and Kagami was staring at him, hands gripping tightly at his shoulders and his eyes —

His eyes were wild.

He was staring — no, glaring — at Kuroko.

Burning and intense, like a predator looking at a prey. He no longer looked flustered and the blush melted off his face. His breath stilled. Kagami's aura swayed and loomed over him, forming the beastly Tiger that Kagami was. And for a moment Kuroko felt he was about to be eaten alive. Reminded of how he felt when he was facing Heavy Seeds like Aomine or Murasakibara face to face in the court, their killing intent forcing him to submission. He felt his breath hitched, a Light Seed cowering beneath the stare of a powerful alpha. A cornered prey.

He swallowed.

But few seconds after a heavy silence, Kagami loosened his grip. He looked away, seeming guilty.

Then he withdrew his hands completely.

"S - sorry." He heard Kagami said. "I… I didn't know what came to me. For a second I thought — " His eyes darted towards Kuroko again.

Then he sniffed the air around Kuroko, looking very unsure.

A look of realisation hit him. "Oh," He muttered, more to himself. "Ah, I guess I was wrong."

"Wrong,"

Kuroko repeated incredulously.

"Yeah, sorry dude. My bad." Kagami looked sheepish.

Kuroko didn't even get what just happened. Or what was wrong exactly.

Kagami suddenly said something about scents then he flustered, shoved Kuroko when he came to inspect the change in complexion, he stared him down like some vermin and then admitted he was wrong.

That totally made sense.

And that was the first time the issue with Kuroko's scents came up.

Kawahara and Fukuda were Primates, but Furihata — who was a Shibainu Light Seed — was the second one to mention anything about Kuroko's apparently peculiar scent.

"Whoa, Kuroko," he had said one day at the locker room after a day's training — Kagami at that time was away on permission to meet his parents — he had a strange look on his face when he looked at Kuroko.

"You smell different!"

This again? Kuroko rolled his eyes inwardly.

At least Furihata didn't look like he was about to glare the shit out of Kuroko.

"Why, Furihata-kun. How do I smell like?" The question wasn't really meant as a question. He just said it because it seemed polite to react to that claim.

"Hmmm," Furihata leaned in to sniff Kuroko, but not so close as to warrant a Stalker restraining order. "I dunno, it smells kinda faint… but it's really, really nice… Did you wear cologne?" He had a heady sort of look on his face, entranced.

Kuroko raised an eyebrow. He never wore cologne.

Then Kawahara and Fukuda suddenly jumped into the conversation.

"Whaaaatt? What's going on? How's Kuroko smell like?" They tried sniffing like Furihata did, flinched at how sweaty and stuffy Kuroko smelled instead.

"Ugh! Manly sweat! The hell are you talking about, Furi?"

The subject of Kuroko's scent was then casually dropped amidst the joking trio.

—

After that, they were given break from the team training, to celebrate Christmas and New Years. Coach Riko and the Captain arranged a party for Christmas at Kagami's place, followed by a temple outing for the New Years, which most of the team agreed to (except Tsuchida who was going to spend Christmas with his girlfriend). Kagami grudgingly agreed for the use of his house and in charge of the cooking as well (after everyone pretty much begged him to save them from Riko's cooking).

Kuroko mostly stayed at home during the break, occasionally going for a jog or play a little basketball at the neighbourhood court — but it got too cold he couldn't afford to play outside for too long. He usually spent most of his time with Kagami — he realised — that it was sort of weird that he didn't have anything else to do. Kagami was away for a week or so to spend time with his parents in America, the others probably had their own plans too. So until the Christmas party, he thought he'd catch up with some reading and maybe walked Nigou around the neighbourhood later. He'd abandoned this hobby for quite a while.

As he browsed through his bookshelves idly, when a book fell to the floor with a thud.

He bent his knees to pick up the book, reading the title, "Understanding the Beastly Call: A Weremanity Guide Book."

Kuroko paused.

He seemed to forget this book existed.

Tetsuya wasn't a Primate, but he was never interested in the business of Seeds classes or the werepeople society in general. He was raised by Primate parents and grew up in a community with mostly Primates, went to a completely ordinary Elementary School which again, sparsely had students of other species. Only when he entered Teikou, did he started to integrate into their society, having a whooping 75% of the students being werepeople consisting of mostly Middle and Heavy Seeds.

Even then, his main focus had always been Basketball. He lacked the common sense of a wereperson.

His grandmother was a wereperson married to a Primate. She was the only one in the family to ever tell him anything about them. Most of his knowledge about the werepeople came from her — which wasn't much, as he wasn't raised with a need to know more — nor had he an interest for it. He remembered the time when it became apparent that he wasn't a Primate like his parents were, he was around six years old.

And the first to discover it was his grandmother, she started to spend more time with him since, teaching him the basics of how to become a wereperson — how to control his 'true form', how to hide his aura, how to use his instincts and especially — how to become invisible.

"You must never let others know of your true form." She used to warn him for the umpteenth time. "You must learn how to disguise yourself. Exposing your true form is the same as being in the nude, you're vulnerable."

Later on, he later learnt that indeed, exposing your true form was quite literarily, the same as being naked, despite the fur and all. Others managed to use it for intimidation though, Kuroko couldn't really tell the difference.

Not that he could do any intimidation like Kagami and Aomine did, he was just a Light Seed. He would be lucky if he could intimidate a cat.

He always thought how unfair it was for Seeds heavier than his had the advantages to physical abilities and natural talent at sport. After 3 years in Teikou, surrounded by various Seeds classes, however, he came to understand how their personalities coincide with their true animal forms. For example, Aomine was slick and powerful, wild in his way of playing basketball with reliable instincts, like his Panther counterpart. And the way he grew more aggressive and predatory spoke of his lineage too.

How clever and quickly Kise could learn his opponents' moves, his cunning hidden beneath a 'winning' personality, the cleverness and versatility befitting a Wolf. How Midorima obsessed over precision, critically specialised in shooting perfect shots as if he evolved into the role, like a Cheetah. Even Murasakibara's laziness could be chalked into a Bear's habit to stock feed and hibernate as well… Kuroko didn't need to start describing how perfectly fit Akashi's true form with Akashi's own personality.

And Kuroko…. was just Kuroko.

He actually never really thought of himself as part of the werepeople. His severe lack of knowledge about them was made obvious when certain issues other than Basketball came up.

Such as scents.

Kuroko had the keen senses of the average werepeople, he could distinct each person's unique scent but chose not to dwell too much about it. After all it never had any use in studying or basketball (especially since everyone's scents got mixed up whilst playing basketball, it was best to learn how to block them). When people talked about scents, he paid no heed of it either. Although, when Kagami first told him that he was scentless, he had been shocked.

Was that how he appeared to other people? No wonder people never seemed to notice his presence.

"Kuroko… You… you smelled."

That was what Kagami told him last time though.

Kuroko pulled up his arm to his nose and sniffed.

Yeah, that didn't work. He couldn't really tell.

He wondered if the other werepeople could smell their own scents. He couldn't ask his grandmother anymore because she died last year, before he entered Seirin. Maybe… he should ask about it to someone else.

—

The Christmas party and the New Years' temple outing went without a hitch. Kagami never acted off anymore and the subject of scents didn't come up, completely forgotten. School started and the rest of the team began their intense practice again for the next championship, Riko's father dropped by once in a while to tighten up the already too-tight-and-about-to-snap training menus. Although after that they did get some nice aftercare massages to avoid muscle damages.

When the examination week was rapidly approaching, they started having study groups to help with Kagami's hopelessly atrocious grades, the seniors were more than eager to beat him if necessary. Soon, the seasons changed. The crisp cold slowly melted away as green grass began sprouting in place of the white blanket of snow that covered the ground, the temperature warmed up considerably, although it was still too cold to play basketball outside.

With the Spring season closing by, another peculiar subject arose.

"It's Spring, huh… it's 'that' time around again." Furihata blurted dreamily at one of the study sessions.

Kuroko looked up from his notebook and gave him a puzzled expression. Kagami seemed bent on passing out on the table, or pretending to anyway. He'd get three slaps of the punishment ruler later, Kuroko mentally noted. Fukuda also looked up at Furihata.

"What do you mean 'that', Furihata-kun?"

Furihata inexplicably exploded in red.

"You know, that!" He flustered — much to Kuroko's confusion. The blush dissipated slightly after a second, deciding it was alright to talk about it in a room full of boys anyway. "You know… Heat Week? In like, few weeks or so? Like… uh, you know." He uttered, almost in a whisper.

It clicked.

"Oh,"

Fukuda's Primate brain skipped that information and he continued solving problem no. 4, groaning into his notebook.

Right. The Heat Week. The twice a year annual event when everyone (werepeople, not Primates) decided to lock themselves somewhere for a week until their uncontrollable primal urges to procreate ran out.

That.

Kuroko shifted in his seat uncomfortably, which went unnoticed by Furihata.

"Well, I have no girlfriend… so no luck this Spring either." Furihata sighed mournfully. "I mean, it must be great to have a partner to spend the Heat Week with. I never even had my first kiss yet — how can I even — Err." He cleared his throat as the blush reached to the tips of his ears.

"You catch my drift?"

Kuroko really didn't.

"Yes, Furihata-kun."

He humoured him anyway.

Fukuda was trying to solve a math problem. Kagami had woken up somewhere along the line as Furihata lamented his Heat Week woes, lazily observing them instead.

"Kuroko, are you going to spend it with Touou's manager? I'm so jealous." Furihata said as Kuroko plotted how to get away from this particularly uncomfortable subject.

"Momoi-san and I are not… like that."

He decided it was best not too say too much.

Furihata gave him an incredulous look. "Really? Even though she always said she's your girlfriend?"

"She is rather persistent, however we are just friends."

"Hmmm. Does it matter though? You can just have fun with it. It's just a week."

Werepeople's take on promiscuity. Right.

"I do not wish to impose. Furihata-kun." Kuroko replied shortly, eager to divert the topic to something else.

Furihata seemed to regard his reply into another take.

"Oh," he looked like something clicked in his head, "Oh I get it, you're the type who mates for life, right? That's cool. I'd like that too." He grinned sheepishly, eyes slipping into slits as he blushed.

Well it wasn't exactly correct, but not incorrect either. He'd let it go at that.

"So what about you Kagami?" He suddenly turned to the quiet redhead. "You have someone to spend it with right? I mean, you're so popular now after we won the Winter Cup. I saw a cute girl confessing to you the other day!"

Well, that was news. Kuroko didn't know that. But at least the topic had moved on from his general direction.

Kagami made a noncommittal noise instead of a proper reply.

"Whoa, you do? Who? Do I know her?" Furihata leaped in excitement, knocking a few of Fukuda's books off the short table, earning protests

Kuroko stared interestedly at Kagami, waiting for his reaction.

Kagami grunted, looking disinterested.

"My parents … last time I met them, gave me some proposals… there's been mating offers. Or somethin'. It's nothing huge." He darted his eyes everywhere but at Kuroko. The latter's eyes widened slightly.

Mating offers.

Kuroko had heard it before. Similar to sperm donor for the Primates, but less clinical. Theoretically, because of werepeople's low fertility level, it was highly recommended to actually mate physically — have sex — in order to ensure conception, as it has significantly higher chances for the seeds to attach through the act of knotting at the peak of the mating climax. The Heat Seasons especially, were the prime time to conceive children, as it was the moment when the werepeople's fertility level reached its peak, before dwindling the following days.

He heard hiring a Mating Donor was ridiculously expensive, especially Heavy Seeds Donors — how much did it cost to hire Kagami?

Alright, that was… weird. He did not want to know how it worked; he'd read it from the book he found weeks ago. But he couldn't help but to feel curious… and slightly apprehensive. Kuroko didn't know why.

"Whoa. Whoa, that… is awesome. You're only sixteen and you already got offers? Man, Heavy Seeds are so different from us." Furihata exclaimed in disbelief, staring at Kagami in awe. "Are you going to accept?"

Kagami suddenly locked eyes with Kuroko. And he kept staring as he spoke again.

"I don't know … I think I'm going to refuse them."

Kuroko was unsure why he felt the need to gulp deeply.

"Huh, why? Such a shame!"

Kagami's gaze fell and he sighed exasperatedly. " 'Coz I'm only sixteen, idiot! Who wants to have kids at this age?"

Actually, sixteen was just barely the permitted age for Mating Donor. The society encouraged the werepeople to breed young, to increase chances of producing more werepeople children because there were so few of them. But Kuroko guessed it made sense in general. He couldn't imagine having kids at sixteen either.

Werepeople's society was complex and fairly different from Primate's. Especially in the aspect of romantic relationships or having families, they were much more open. He'd known people who were half-siblings, their parents weren't married, yet they treated each other like families. Some prefer to mate for life due to the influence of their true form, but others were not as loyal. This clash in culture confused Kuroko at times, as he'd been raised with Primates' moral values.

The conversation went on normally, still straggling around the subject of the Heat Week, which Furihata was intent on discussing. Kuroko stayed silent most of the time, though, knowing he had nothing to offer to the discussion. He was already uncomfortable as it was.

By the time they stopped studying, it was around dinner time. At some point Kuroko had stopped the Heat Week forum because they needed to continue with the study sessions. Now he was helping Kagami to prepare dinner — it was late anyway and going down to grab some burgers seemed to be a pain, Kagami claimed he'd had some leftovers because Alex recently went back to L.A.; he'd made too much curry.

"Oi, Kuroko, care to explain why you looked like a dead rabbit back there when Furihata yapped about the Heat Week?"

Kuroko stopped chopping carrots suddenly, thankfully he'd not hurt any fingers.

Well, Kagami was always the blunt type.

"Yes, it bothered me. It is a subject I am unfamiliar with." He told him, resuming the chopping.

Kagami gave him a weird look. "Unfamiliar, how? I mean, we all had them — " he stopped. "Wait. Wait a goddamn minute. Did you — I mean, not to be crude, but have you… ever… ?"

A pair of flush pink ears were his answer.

"Y - You actually never!?" Kagami sounded mortified.

Kuroko promptly 'nudged' at Kagami's side a little too forcefully, the taller boy yelped in pain.

"So loud, Kagami-kun." Kuroko narrowed his eyes at him. "Yes, I have never experienced the Heat before. I know it is considered unusual, it may appear that I am a late bloomer."

The average age for teenagers to experience their first heat was 12 - 14 years old. Kuroko was 16 and would be 17 this January and had never been in heat. He wondered if his growth was really stunted after all.

Which also worried him considerably, as he had researched about it before. It would seem that sometimes cases like Kuroko occurred, and that it'd be harder to deal with for when the First Heat finally happened to him. The article claimed the stunted hormones and sexual drives (that were already pretty strong for werepeople to begin with — not that it ever affected Kuroko) that were held back from its natural time to discharge, would come out in full blast when it did finally happen.

From what he heard from others, being in normal heat already sounded unpleasant as it was, but to experience a doubled or tripled effects than normal, on his first time, was infinitely worrying.

He had missed the last 2 years, since his 'natural time to discharge'. He's missed approximately 4 heat seasons at very least. Kuroko started sweating. Recently he'd feel a bit out of sorts lately, like his instincts told him the time for the Heat would come soon for him and he had no idea who to turn to at a time like this. None of his family members were Werepeople. And his grandmother already died. He knew other people locked themselves up for a whole week during… how would that even be possible with his primate parents around?

It looked like all kinds of emotions were displayed on Kuroko's face, because Kagami was staring at him with an odd look on his face (a year of constantly spending time together had given Kagami the means to decipher his emotions, it seemed).

There was a heavy silence between them that lasted for a while.

"Your parents… they'd tell you what to do. They'd put you in the Heat Room." Kagami said, his face serious. Kuroko had never seen him look like that before.

Kuroko shook his head slightly.

"My parents are Primates. We do not have any… Heat Rooms." They were not exactly rich either. Kuroko's house was pretty small.

He didn't miss Kagami's face when he looked at him with shock written on his face.

"Your parents…. they are Primates?"

He said it like Kuroko had told him he was a spawn of the Xenomorph.

Kuroko shrugged.

"My grandmother was a Light Seed. I was raised in mostly Primates community until I went to Teikou. She taught me a few things about the werepeople, basics of controlling true forms and hiding my aura. But she died before I could ask her about… this."

Kagami scrambled to regain his composure.

"I… I see." Kagami nodded, understanding. He looked thoughtful for a moment.

Kuroko had chopped the rest of the carrots. The silence was a bit unnerving.

"Kuroko, I think," Kagami said, drawing his attention. "I think your First Heat will come this season. No, that was wrong - I'm sure of it. I've smelled you — I told you before right? You were scentless before. When we first met. I don't know exactly when it started — because in court, the scents got mixed. I could be wrong but — I think it started maybe after Winter Cup, or during the game with Rakuzan. It was faint at first."

Kagami paused for good measure.

"At the gym storage," He continued. "When there was only the two of us, I could've sworn… I distinctly smelled you. Your scent. It got stronger over time. I think… I think it's a sign. Even now… I can smell you. Clearer than before." He finished.

Kuroko swallowed.

He knew.

"I… I heard. It was worse," He started, looking at the chopping table. "For late bloomers, I mean. I was supposed to get my First Heat two years ago… I didn't pay attention at first, because of Basketball and Teikou. I didn't seek help. I didn't know. Never talked about it. Never asked anyone. I thought it wasn't significant."

He only recently knew there was treatment for Stunted Heat condition, dealing with its tripled effects by himself now would pose a threat. Dangerous. He had no clue how to deal with a normal Heat, how could he know how to deal with a doubled or tripled effects of the heat? He couldn't exactly tell his parents. Their Primate nature would just sweep the information off of their brains. He grimaced.

Kuroko didn't like feeling so helpless.

"I'll help you." He heard Kagami said.

Kuroko looked up at him.

"I mean… if — if you let me." A crimson blush bloomed on his cheeks, he cleared his throat. "I have experience with… Heat Partners. I had my First Heat when I was 13. I've only ever missed one heat season, alone. Also… I have had both genders, as partners. I've been educated in the States — about Stunted Heat and how to deal with it. I still got the book somewhere."

Kuroko let the information sink into his brain.

He didn't know whether it was the fact that Kagami, born as a Heavy Seed, with massive Basketball talent, perfect physique, handsome face, a spectacular dick (he didn't mean to stare but he'd seen it in the gym showers by accident) and living in his own flat. Kagami was apparently also, wildly experienced in sex with different partners. Much more than Kuroko ever had. He didn't know which one pissed him off more. Damn American Returnee.

He promptly pushed out the urge to perform Ignite Punch Kai on Kagami's spectacular dick, as there was a more important issue at hand.

"You mean," He started. "You'd be my Heat Partner?"

He didn't expect Kagami to explode into a myriad of different shades of red more impressive than his own hair.

"Y — yeah tha's what I'm sayin'!" for some reasons he lapsed into english with an odd accent.

Kuroko thought of it for a second.

Homosexuality was considered normal among the werepeople ever since they invented the Parasites. It wasn't a social problem. But not all werepeople were bisexual, they had their own preferences. He didn't know Kagami was bisexual though. Kuroko had heard how it'd hurt for first timers. He had even less idea at how to perform the act between men. This situation would, however, be at his advantage… as Kagami would know. What to do with… the… sex.

Kuroko tried to ignore the heat rising in his cheeks. He was surprised to think that if he'd have to lose his virginity to a man, he'd rather choose Kagami out of all available options.

That was a very odd thought.

"Alright. I accept your offer, Kagami-kun."

"R — really?" Kagami exclaimed. Face red.

"Umm, and, Kagami-kun?" He added, couldn't help the blush from seeping out onto his pale complexion. "Please do be gentle with me. It is my first time."

Kagami's face tightened up so much Kuroko thought cracks would appear on the sides.

—

The Heat Week would start right after the Examination Week. Kuroko and Kagami spent more of their off-school off-club time together for more study sessions to prevent Kagami from staying back for another year and so he could enter the next championship.

Their relationship began to change since the day Kuroko accepted Kagami's Heat Partner proposal. The redhead started giving him long looks, during their study sessions or when they were having lunch at school. They made Kuroko fidget slightly but he didn't make it a huge deal. Then it slowly developed into innocent touches; on the arm that lingered seconds too long, or on Kuroko's shoulders, Kagami once went as far as to daringly touched his waist. He was lucky he only got away with one normal gut punch from Kuroko.

When Kuroko gradually became used to the touches, then Kagami started to grow bolder. He began to take Kuroko's hand in his, when nobody was looking, lacing their fingers together. Then he would give Kuroko brief hugs that stretched longer and longer the more he gave him. Kuroko thought maybe it was an attempt to familiarise themselves with the touching for the Heat Week. Well, he knew there would be much more than just touching when it happened (no he did not just blush furiously at the thought), so Kuroko decided to… accept Kagami's touches.

He noticed Kagami was touchier when they were left alone at his house, the other First Years had gone home early for dinner after their study sessions. First he'd sit next to Kuroko as the shorter boy tidied up his notebooks, then he'd lean close until Kuroko was overwhelmed by Kagami's scent and his body radiated comfortable warmth. Kuroko didn't hate it. His scent seemed to have a curious effect on Kuroko. In fact, he liked it. He wondered if this was the famed Heavy Seed's pheromone. He never paid much attention to it before.

Kagami then would put his arms over Kuroko's shoulder, casually at first. He'd stay that way for a few minutes, waiting until Kuroko finished packing. Then he'd lean closer, his lips inches from Kuroko's ears and he whispered in a deep voice that sent chills up Kuroko's spines.

"Would you stay and let me cook you dinner?"

Kuroko chalked it off as being lured by Kagami's promise of divine food and perfectly delectable homemade Vanilla shakes. He wasn't sure if he could believe the reasoning himself. Sometimes he thought Kagami was trying to charm him through his stomach.

Mere touches became half-hugs, half-hugs became snuggles on the couch. Kuroko really wasn't sure how he'd let Kagami persuaded him into letting him do what he wanted — Kuroko felt like he couldn't resist Kagami when his head was heady with Kagami's seductive scent filling his senses and blurring his ability to judge logically. He'd stayed over on the weekends at Kagami's for studying, games and movies. When they were watching movies on a Saturday night, Kagami boldly put Kuroko to sit in between his thighs on the sofa while his arms wrapped around Kuroko's waist. He lazily sniffed at the crown of Kuroko's ice blue head and inhaled deeply as he watched the movie on the TV.

Kuroko meanwhile, was having a slight brain breakdown.

He had never dated anyone and he had no siblings. He was unused to be surrounded by someone else's warmth; to be touched so intimately. He also didn't know how much he actually enjoyed snuggling like this with Kagami. But then he remembered how touchy feely foreigners could be and thought maybe Kagami always acted this way with his American friends.

The thought managed to calm down Kuroko's wildly beating heart.

"Hey… tell me about yourself?" Kagami mumbled, his lips still on Kuroko's hair. His palms were making soothing circles on his tummy, it was comforting.

Kuroko crooked his neck slightly to look at Kagami. "Like what?"

Kagami looked thoughtful for a moment.

"Like… how you found out you weren't a primate."

Kuroko told him then. He had an accident when he was six, it was pretty bad because he went to a coma. The whole family waited for him to wake up at the hospital, after a few days he did. When he woke up he saw his parents and grandparents, but the look on his grandmother's face was both a mix of relief and shock. After he was discharged, his grandmother was the one who took care of him at home while Kuroko's parents worked. She told Kuroko he was a wereperson and that she needed to teach him a few things to become a wereperson.

"I didn't really understand what she was talking about, I told you I grew up in a mostly primates environment. I didn't have anyone of other species around."

Kagami made a humming sound. Kuroko had grown really comfortable with their position.

Kagami and Kuroko didn't pay attention to the movie anymore, instead Kagami listened to Kuroko's story as they snuggled closer. Kuroko never knew Kagami was such a cuddler; he was big and warm like a human furnace, it was alarmingly cosy being in his arms.

He told him things like how he came to know the werepeople society when he entered Teikou. How bizarre the difference between primates and werepeople, he felt like he was the main character of a fiction. How he interacted with the others who was shocked to know he knew virtually nothing about their world. At that time, however, he didn't tell anyone he came from primate parents because his grandmother told him not to. He only told them he lived and grew up in a primates-focused district.

The movie had finished an hour ago when Kuroko was done telling his life story, feeling as if a weight was unloaded off of his chest when he was done.

Kagami looked at him with a look gentler than Kuroko had ever seen him, then the redhead leaned to press his lips on Kuroko's forehead.

—

Kuroko put a ban on sleepovers and snuggles during exam week. He specifically told Kagami; should he not get passing grades, then they might as well forget about their 'arrangement'.

Kagami had groaned in protest, but didn't actually voice it.

He looked up from his notebook to stare at Kuroko. There were only the two of them left in the room. "Fine, but just let me do this." He pulled Kuroko down to his lap and started mouthing at Kuroko's pale neck, trailing wet kisses and gentle nips all over the surface.

—

Later on, Kuroko learned that Kagami had marked him when he saw a series of pink teeth marks adorning his neck and collarbone the next morning, then his teammates teased how he reeked of Kagami's scent.

Kagami received an Ignite Punch Kai to his gut for his trouble.

TBC.
