Kuroko always knew he was going to be an omega. Ever since the day he understood how the whole alpha, beta and omega thing worked, he just knew that he would be an omega. His mother was an omega, his father was a beta, there wasn't a single alpha in their lineage. Which is why he wasn't surprised to present as one. Of course he found it annoying as he didn't like "being" so submissive to others, especially the alphas who thought they were hot stuff, but he couldn't change who he was. The blue haired boy had just turned eighteen and though he may seem young, his parents really wanted him to find a mate.

"Tetsuya, what are you going to do when your heat hits? You've never had one yet, right?" His mother says with a concerned voice.

Kuroko had yet to have his first heat, even though he had presented as an omega at the age of 13. The blue haired boy was eighteen, an omega, and unmated, and he was pretty happy with his life without a mate.

His friends, on the other hand, were really surprised when they found out Kuroko was an omega. They always thought he would be a beta. Kagami, an alpha and also the blue haired boy's best friend slapped Kuroko on the back and said,

"Well, at least when you get your first heat your parents won't hear you. You're moving out, aren't you? Boy, you have no clue how embarrassing my ruts were when I was younger."

The blue haired boy nodded, "Yeah, my parents told me that I should learn how to handle myself out there. So I'll have my own little apartment sometime this week."

To be honest, Kuroko was scared of having his first heat, mainly because he read about how late heats are unbearable and hard to get through alone. He contemplated taking suppressants to hope that he would never have to have his heat, but the blue haired boy knew that would probably make his situation even worse. So he waited. Kuroko wasn't sure when it would happen but he assumed it would hit him like a train.

Aomine, an alpha, was also the blue haired boy's friend. When he figured out that Kuroko was an omega, he grinned and said, "I want you to meet my mate! Maybe he can help you with how to mentally prepare yourself and stuff. I don't know how the whole heat thing works with omegas but maybe he'll be a little helpful."

It was decided that Kuroko, Kagami and Aomine would meet Aomine's mate and some of his friends at Maji Burger. The blue haired boy liked having the two alphas as his best friends, it made Kuroko seem hidden underneath their strong scents so many unmated alphas didn't try to flirt with him.

When they got to Maji Burger, Kuroko saw a blond, redhead, green haired and purple haired boy sitting at a table. Aomine approached them and lightly kissed the blond before saying,

"This is Kise Ryouta, he's my mate."

Kise seemed to sniff the air before beaming at Kuroko,

"Waaaa! You must be the omega, you're so cute. Wait, we have to introduce you to everyone."

The blue haired boy tilted his head to the side like a curious cat and said, "I'm Kuroko Tetsuya, omega and eighteen years old."

"Midorima Shintaro, beta, seventeen years old."

"Murasakibara Atsushi, beta, eighteen years old."

"Akashi Seijuro, alpha, twenty years old."

The blond laughed and embraced Kuroko, "And I'm Kise Ryouta, omega, seventeen years old."

Kuroko let Kagami and Aomine introduce themselves to the group and then they all sat down to grab a bite to eat. The blue haired boy only had a vanilla milkshake and he sat quietly beside Kagami. He felt awkward. The blue haired boy almost wanted to shift forms and run off, but he knew that he only felt nervous because of Akashi's overwhelming scent. The redhead smelled really good to Kuroko. He almost smelled like hot chocolate; or more simply, he smelled like home.

When Akashi spoke, his voice was like a warm breeze on a cool summer morning right at the break of dawn.
When Kuroko's eyes met those red orbs, he couldn't help but freeze and stiffen under that strong gaze. The blue haired boy quickly looked away and continued to talk without making eye contact with the redhead.

See, Kuroko didn't believe in the blood bond. He thought that every bond was the same no matter who the person was. Akashi, on the other hand, believed in the blood bond which was a strong connection to one person who is destined to be your mate. The redhead knew that his blood bond would smell irresistible and he smelled that all over Kuroko. The boy simply screamed blood bond. It was quite obvious that the blue haired boy was inexperienced, either that or he already had an alpha.

Akashi knew Aomine and Kise were going steady but he didn't know about Kagami, and his closeness with Kuroko made him believe that they were mated. The redhead wasn't sure how to approach Kuroko and he definitely didn't want to make the omega feel uncomfortable but he knew that he would not have anyone but him.

"Ah, Kurokocchi, you've never had your heat?! That's so strange. Normally your heat would happen within the first few weeks of presenting." Kise exclaimed, "Well...your scent is definitely very unique."

"What does that mean, Kise-kun?" The blue haired boy asked curiously.

The blond puckered his lips slightly, trying to gather his thoughts, "Mm, your scent is very hidden. Like you're not even there. I think your heat will be triggered when you find your blood bond or soulmate, whatever people call it these days."

The blue haired boy seemed passive to this, he didn't really know the difference between love and friendship. It seemed the same to him, he loved Kagami but he didn't want to mate with him. He loved Aomine as well, but didn't want to mate with him either. He wasn't really sure if love was supposed to feel different.

When they made their way home, Akashi walked the blue haired boy all the way to his house since the redhead lived farther away than the rest of them. Kuroko would be lying if he said he didn't enjoy Akashi's presence but something about the redhead kept the blue haired boy alert.

Once at Kuroko's door, the redhead decided to take a giant leap by asking,

"Could we exchange cellphone numbers? I would really like to get to know you better."

The blue haired boy's eyes widened. He wasn't popular at all and no one really talked with him. Yet the most stunning alpha he has met was asking for his number. Kuroko nodded and they quickly exchanged numbers.

"I guess I'll see you tomorrow?" The redhead said with a smile while handing back the blue haired boy's cellphone.

When Kuroko grabbed it their hands brushed together and something in his body jolted. He nodded lightly and watched Akashi leave. Kuroko got up to his room and flopped onto his bed. He stared at his hand, thinking about Akashi's warmth and whispered, "Tomorrow..."

When the next day came, Kuroko moved into his new apartment and of course, everyone helped the blue haired boy get settled in.
While Kuroko was setting up his room, Akashi slowly walked in and said, "This is a really nice place by the way."

"Thanks, it's going to be annoying to clean by myself though."

"Well, if you want I can help you from time to time, it's not easy living alone." Akashi muttered.

All of the sudden, the blue haired boy was very aware of the redhead; everything about him from his appearance to his scent. Kuroko instinctively brought his hand to his neck, a movement which showed that he was protecting himself from gaining a bond mark. Akashi noticed and chuckled,

"Afraid I'm going to bite you?"

The blue haired boy lowered his hand and shook his head, he trusted the other. Akashi quickly approached Kuroko and lightly brushed his lips against the blue haired boy's neck.

Kuroko shivered but couldn't move from his spot. He let Akashi scent him and then heard the redhead whisper in his ear,

"You should be afraid."

When all his friends left, Kuroko sat in his room yet couldn't get the redhead scent to go away. No matter where he went, Akashi's scent lingered.
The next night was unbearable for the blue haired boy. He continuously tossed and turned, feeling an uncomfortable tingle all over his body. All he was able to think about was Akashi. When he imagined the redhead sleeping next to him, he began to calm down and eventually fell asleep, but in the morning, it got worse.
The first thing he noticed was how hot it was in his room. Second thing he noticed was the slick producing from that familiar area which he didn't want to think about. Third thing he noticed was that he was hard. Kuroko struggled to get out of bed, but he grabbed his cellphone in a panic and ran to the bathroom.

The blue haired boy didn't bother taking off his clothes, he simply sat down in the bathtub and let cold water wash away the heat. When nothing was getting better, the blue haired boy quickly called Akashi and whimpered, "Please...help me, Akashi-kun."

The redhead tried asking Kuroko questions but the blue haired boy dropped his cellphone onto the floor to curl up and try to escape the heat. When Akashi got to Kuroko's apartment, he was able to smell him everywhere. When Akashi got into the bathroom, Kuroko scent overpowered all his senses. The blue haired boy was shivering, his pupils dilated and he wept due to the pain.

"Tetsuya...you..you're in heat." Akashi said as he quickly approached Kuroko and carried him out of the tub.

The moment their skin touched, the blue haired boy jolted and let out a breathy moan.

"Sorry...Akashi-kun, I didn't even realize that I called you. I'm sorry. I'm so sorry." Kuroko mumbled as his numb fingers tried to pull the redhead closer to bury himself into that beautiful scent.

Akashi stroked the blue haired boy's wet hair and undressed him so that he didn't have to sit in wet clothes. The redhead covered Kuroko in a towel and then carried him back to his room. Akashi had to admit, the blue haired boy's scent was driving him insane but he had enough self-control not to claim the boy right now.
Once in bed and tucked in, Kuroko whimpered when the redhead pulled away, "No, please stay. I can't do this alone, please stay with me."

"Tetsuya, I don't know what I might do to you if I stay."

The blue haired boy froze, eyes widening in fear. Akashi quickly calmed him down by saying that he wouldn't claim him unless he was given permission. In the end, the redhead curled up beside Kuroko and pulled him into his chest. The blue haired boy's heat seemed to be satisfied with simply Akashi's scent and he fell asleep almost instantly.

The morning after, Kuroko's heat only intensified. The feeling of being so close to an alpha yet not being filled made Kuroko's heat unbearable. The blue haired boy pressed his face into Akashi's neck and breathed in his scent. He felt himself relax at the smell of the redhead.

Akashi woke up to Kuroko's whines and gently stroked his hair to try and help.

"Akashi-kun...please... I need you."

The redhead stared at the blue haired boy's face for any signs of uncertainty. When he saw nothing but the simple desire to be with him, Akashi slowly pulled off his shirt and moved over Kuroko.

They barely knew each other; they had only spent four days together. Less. Yet they knew each other for an eternity.

Warning! The explicit scene begins here. Feel free to skip!

The redhead brought their lips together in an electrifying kiss. Kuroko moaned into the kiss and pushed back, eager for more. The blue haired boy's skin felt like it was burning and the animal inside him howled for release. Kuroko flung his arms around the redhead's neck and pulled him closer together.

"S-sorry, I'm sorry Akashi-kun... I can't... I need, please."

"Shh," The redhead cooed as he slowly reached down to take off Kuroko's boxers, "look at me, Tetsuya."

The blue haired boy gasped and instantly came when Akashi stroked him.

"I'm sorry..." Kuroko mumbled as he clung to the redhead.

Akashi lightly brushed away the hair covering Kuroko's face and let out a small growl, "Stop apologizing. Heats are normal and I want to help you through it."
The blue haired boy shuddered as the redhead kissed his neck and slowly moved down to kiss his collarbone and chest.

Kuroko felt a sudden sense of fear when he felt Akashi's bare skin against his own and the redhead noticed how the blue haired boy tensed under his touch.

"Are you okay? Do you want me to stop?" Akashi asked.

"Are you going to claim me...?" Kuroko answered with a question.

The redhead brushed the hair away from Kuroko face and planted a light kiss on his forehead, "Only if you want me to."

Kuroko nodded for the redhead to continue and gasped when he felt a finger circle his entrance. He gripped the redhead's arms tight. When the redhead easily slid one finger into the blue haired boy's tight heat, Kuroko jolted and tried to pull Akashi impossibly closer. The blue haired boy's heat was quite efficient. Akashi was able to prepare him faster and Kuroko felt little to no pain. Eventually, the redhead had three fingers carefully stretching him open and Kuroko was only able to beg for more.

"Akashi-kun, help me..." The blue haired boy whispered as he pushed back against the redhead's fingers. Akashi was more than happy to comply as he pulled out his fingers and showered Kuroko's face with kisses.

"Are you sure you want me?" The redhead asked.

Kuroko nodded frantically when he felt the tip of Akashi's erection brush against his entrance.

"Do you really want me? Or are you willing to submit to any alpha?" Akashi teased a little.

The blue haired boy's nails dug into Akashi's arms as he became more desperate, "Just you. Only you, Akashi-kun."

As Akashi slowly pushed in, the blue haired boy let out a small whine. The redhead lightly stroked Kuroko's hair and waited for him to adjust. Akashi let his fingers run across, up and down the blue haired boy's chest and thighs. The redhead really couldn't enjoy Kuroko enough; he was like a masterpiece.
The blue haired boy pushed his hips back to try and feel some friction. Akashi set a slow pace, much too slow for both of them but he wanted to make sure Kuroko was comfortable. In fact, the redhead was surprised he had this much self control to begin with. Once the blue haired boy became impatient, Akashi thrust faster and deeper. Kuroko let out short moans as his nails dug into the redhead's back.

When Akashi hit his prostate, the blue haired boy whined and whispered the redhead's name. The redhead wrapped his arms around Kuroko's waist and pulled him up.
The blue haired boy sat on Akashi's lap, the new angle allowing the redhead to reach deeper and the redhead simply lay back to enjoy the view.
Kuroko was too far gone in seeking his own pleasure and he quickly moved up and down. When the blue haired boy got tired, he leaned onto Akashi's chest and buried his face into the redhead's neck.

The redhead grabbed Kuroko's hips and thrust up harshly. The blue haired boy moaned loudly and whispered,

"I want you."

Akashi growled as he kissed the blue haired boy's neck, "You already have me."

Kuroko shook his head as he desperately seeked his release, "No, I want you."

The redhead paused for a moment and asked, "Are you sure?"

The blue haired boy nodded, tangled his fingers in Akashi's brilliant red hair and gently mumbled,

"You smell like home. You make me feel safe. I feel this tug towards you. I just… I want you to claim me, I want you to knot me..."

Akashi's eyes widened and he didn't slow down in pleasuring his soon to be mate.

"Tetsuya, submit to me."

The blue haired boy whined and bared his neck to let Akashi join them in a permanent bond. When the redhead's teeth penetrated Kuroko's neck, his knot also began to swell. The blue haired boy came with a shout and gasped when he felt impossibly full. The redhead came only seconds later and held Kuroko close.

Warning! This is the end of the explicit scene.

Their memories came back piece by piece as they lay on top of each other. The blue haired boy rested his head on Akashi's bare chest to listen to the hard thumping of his heart.

Something inside the blue haired boy had settled, as if the animal inside him was satisfied. After catching his breath, Kuroko leaned up and kissed the redhead's neck.

"Mm, Tetsuya, go to sleep."

"Seijuro, don't you want to go out later?"

"You idiot, you're still in heat. Having sex once isn't going to stop your body from wanting more."

Kuroko blushed at the comment and nuzzled his face into Akashi's neck. He felt the fatigue wash over him and decided to close his eyes for a bit.

The tattoo could wait a few days... He thought as he let sleep pull at him.

"Can we get it soon?" The blue haired boy mumbled as he began to relax.

Akashi kissed Kuroko's forehead and lightly stroked his hair, "Of course."

When Kuroko's heat passed, they went to get their tattoos before meeting the others. Knowing that they were each other's soul mates was exciting and it made life easier too. They knew exactly how the other felt and were able to comfort each other. Kuroko never spent a heat alone and Akashi was more than happy to help his lover.

Everyone was quite surprised to see the blue haired boy and the redhead become mates, especially Kuroko's parents. However, they did know that your soul mate could be anyone and were quick to accept them.
They lived peacefully in the comfort of each other's arms and when they died, they died together.
