Kuroo and Kenma had been best friends since… well, ever. Kuroo couldn’t actually remember a time when Kenma wasn’t in his life, vaguely remember their first meeting, but before this? Nothing. Kenma was a little shy at first, but day by day they just became closer and closer to each other, until they reached a point where they did everything together. Even after Kuroo presented as an alpha and Kenma as an omega, they didn’t distance themselves, their friendship just grew stronger.
In his mind, Kuroo treated Kenma just like his very dear friend. In high school he got all protective over him, but it’s normal since Kenma’s very shy and an omega, people often tried to approach him too much. Kuroo only realized his real feelings when Kenma got his first boyfriend while still in high school, that made him crazy jealous. He couldn’t understand what Kenma saw in that little orange alpha, but he couldn’t say what Kenma could or couldn’t do with his life, right? He didn’t have the courage to ask him out before that guy did, so he could just watch and hope for the better.
He tried to date other people too, but nothing made him get over Kenma and it didn’t seem fair to be with someone while thinking about someone else. Kenma and Hinata’s relationship lasted five years until they broke up. Kuroo wasn’t happy about that, but he couldn’t say that he was sad either. Kenma just told him that they decided that it would be best if they remained friends, no further explanation and he didn’t ask too much to not upset him even more.
Even after years since Kenma broke up, their relationship didn’t develop and Kuroo isn’t sure why. He knows that they could be a perfect couple and that he could be a great alpha, but he’s afraid to do some irreversible damage to their friendship. What if he asks Kenma out only to find out that Kenma never actually saw him as a potential partner and this just makes things between them weird? How he, now 27 years old, could learn how to live without his best friend? That’s not happening.
He’s in crazy love with Kenma, but if he can manage to sit and watch TV while he knows that Kenma’s spending his heat with someone else, he can do anything he wants. He wants to tear off his own scalp? Yes, but at least he’s letting Kenma live his life.
It’s crazy to think about this, he and Kenma planned to live together before discovering that their second gender could be a problem, but after presenting they understand that it would be better to both if they had their privacy. Kuroo spends his ruts with someone he trusts and Kenma does the same in his heats, it would be completely fine if he didn’t actually give him details about it. He doesn’t want to know if some dickhead couldn't knot him properly or if he wasn’t rough enough for Kenma’s likings.
Right now he’s sitting on his couch, looking at the TV, but his brain’s betraying him and can only picture the image of another alpha touching Kenma and leaving him unsatisfied. It’s ridiculous to think that someone with the opportunity to spend Kenma’s heat with him wouldn’t do what they can to leave him happy and satisfied.
Thank God he heard his phone ringing, he would become insane if he kept thinking about this for too long. He looked at the screen, seeing Taketora’s name and wondering what he wanted at this time.
“What’s up?”
“Kuroo, hey, um… are you busy?” Tora’s voice sounded a little apprehensive on the phone, Kuroo couldn’t help but be worried about his friend.
“Everything alright? Something happened?” He turned off the TV to hear him better.
“Yeah, well… um, I don’t know how to say it without you being mad at me.”
“Why would I be mad? What’s wrong?”
“You’ll be mad at me because I’m at Kenma’s.”
“Huh? What are you doing there?
“I usually help him when he’s in heat.”
Kuroo couldn’t deny that he’s even more jealous now, not exactly mad, just so jealous that he could die. Why didn't Kenma tell him that Tora’s the one that helps him? He always tells him that these alphas weren’t good for him, it’s just to make him jealous? Like he needed to say all that to him, Kuroo could get angry just from his thoughts alone.
That’s why Tora and Kenma are closer now? Kuroo did notice that they seemed more intimate, not in a sexual way, but started to hang out more and text each other more. They’re dating now? If they are, why’s Taketora telling him? Maybe to torture him even more.
“Still there?” He heard Tora asking.
“Why are you telling me this?” He forced himself to ask, trying to not sound too bitter.
“I need you to come over.”
“Why? Can’t do it yourself?”
“Don’t talk to me like that, fucker, I’m trying to help.”
“I don’t want to see you two having sex.”
“You’re not seeing anything, dumbass, Kenma needs you.”
“Need me? How? Is he alright?”
“Come here and I’ll explain. And be fast.”
The second they hung up, Kuroo stood up and went straight to the door, the only thought in his head was to help Kenma in any way he needed. They live close to each other, it’s only a five minutes walk to Kenma’s building, but he was there in less than that.
He was impatient with how slow the elevator was, he’s anxious thinking about all the reasons that Kenma would need him here and why Tora couldn’t just deal with it himself. When the elevator finally stopped by the Kenma’s floor, he could already see Tora standing in the front door of his apartment, waiting for him.
“Tora! I’m here, what’s happening?” He ran toward him, worried. “Kenma’s okay?”
“He’s fine.”
“Then why am I here?”
“He doesn’t want me here.”
“What? Why? You did something wrong?”
“Let me explain.” Tora looks tired as he wants to do anything but have this conversation. “Kenma probably gonna kill me later for telling you this, but he’s in pain and I can’t help.”
“Why is he in pain?”
“He’s in heat, Kuroo.”
Kuroo’s so worried that he isn’t thinking too much about anything besides Kenma, where Tora’s going with this talk?
“People might think that omegas fold to any alpha available, but isn’t true, they choose who’s good enough to be their mate.” Taketora explained “Kenma’s rejecting me.”
“Why?”
“Because he wants you.”
“How do you know that?”
“When I’m with him, you know, at the function and stuff, he usually calls your name.”
“Huh?”
“Yeah, he likes you so I let him, I’m just here to help.” He shrugged like it wasn’t a big deal, but to Kuroo this is the biggest deal of his life.
He doesn’t understand why Tora accepts that situation but he could ask later, now he just wants to know why Kenma never told him anything. Even if it was just to spend his heat together, Kuroo would’ve accepted it, he would do anything Kenma wanted.
“I know you’re happy to know he likes you too, but right now isn’t about you, it’s about him.” Tora said, pulling him back to reality. “You need to be in your right mind to take care of him, okay?”
“I’m fine. Completely.” It’s a lie. His mouth was dry and he could hear his pulse echoing in his own ears, he’s a mess. A mess that couldn’t wait to be with Kenma.
“Say that to yourself so you're gonna believe it, then. Let me give you some advice.” Taketora offered and he just nodded. “He’s vulnerable now, so be careful. Don’t enter the room without asking and do not approach his nest without asking again if you can. Just let him know that he can trust you this time too.”
He nodded again, of course he’s not happy with the fact that Taketora knows more about Kenma than him, but he’ll try to trust him and listen carefully.
“I brought onigiris, he likes to eat it when he calms down a little and there’s water in his room. In the bedside table drawer there’s condoms and chocolate because he likes it too. Don’t growl at me, I'm helping you!” He crossed his arms and Kuroo felt shame, he didn’t even realize he was doing it.
“Sorry, I’m a little jealous, I guess.”
“Ungrateful.”
“Thanks for the advice anyway, I’ll pay you a drink later.”
“Just don’t let him kill me after telling you his hidden love and we’re good.” He patted his shoulder, starting to walk in the direction of the elevator. “I’m going home, if you need anything, call me.”
Kuroo waved at him before finally slowly opening the door. The apartment was so quiet that he could believe it was empty if it weren't for the slight scent of Kenma’s pheromones in the air. He started to make the familiar route to Kenma’s bedroom, trying to not get so affected by the scent that was getting stronger by each step he gave.
He hesitated for a while, thinking about all the things that could happen if he entered this room. He knows that he won’t be able to hold himself and wonders if that’s what Kenma needs right now. On the other hand, he can’t just turn back and leave him alone. He knocked on the door and waited, but got no answer, getting worried.
“Kyanma? It’s me, Kuroo, are you alright?” Kuroo asked, fighting the urge to just come in.
“I’m fine.” Kenma’s voice sounded slightly weak through the door. “What are you doing here?”
“Can I come in?” Kuroo waited as patiently as he could while Kenma thought about an answer.
“Yes.”
He was feeling like his heart would jump off his chest as he opened the door and his lungs got filled with the delicious scent of Kenma’s pheromones, making him dizzy. The view he’s getting right now it’s the best of his entire life. Kenma’s laying on his nest, dressed only with one of Kuroo’s shirts, looking at him with his big shiny eyes. His face is red and his beautiful long hair is messily scattered across his pillow. He looks like an angel.
“Kuro, what are you doing here?” Kenma asked, forcing him to look away from his legs.
“Tora called me, he told me you need help.” His inner alpha is screaming to get closer to Kenma, to bury his face on his neck and fill his lungs entirely with his scent, but he needs to control himself and do things slowly. Kenma needs that. “You want my help?”
“Only if… only if you want to help me.” Kenma sounds shy, almost uncertain of what to do or say.
“Can I approach you?” Kenma only nodded to him, but he still forced himself to stay in his place. “If you don't use your words, I’ll not do anything, kitten.”
He needs to be sure, needs to hear the certainty in his voice and to know what he wants. Kenma sighed and bit his lips after hearing Kuroo words, almost making the raven fold with his look alone.
“Yes, you can approach me, Kuro.” Kenma watched him, step by step, approaching his nest.
Kuroo kneeled next to him, forcing his mind to stay focused only on his pretty face and to not hear his horny inner alpha.
“Can I touch you?”
“Yes.”
Kuroo reached out to touch his face, feeling the hot skin burning under his palm. Kenma inclined his head to feel better, Kuroo's gentle touch caressing his skin.
“You made a beautiful nest, you know that?” He praised and smiled when Kenma started to purr. So cute. “You think I don’t want to help you?”
“I think you don’t like me enough to help me.” Kenma was always this honest with him, if Kuroo asks, he usually gives him straight answers like that.
“Why do you think that?”
“You never showed any interest in being my mate.” Kenma looked sad saying that. “I tried to make you jealous too, but if you thought that I could be a good omega for you, you would’ve done something.”
“That’s why you always told me about other alphas?”
“Yes.”
“Sorry, kitten, I’m so dumb for not doing nothing.”
“What do you mean?”
“I got crazy jealous, but I didn’t realize it was on purpose and didn’t do anything about it.”
“So you like me too?”
“Kitten, I love you. With all my heart and soul. It’s always been like that.” He smiled again, putting Kenma’s hand above his heart. “Sorry for being so slow.”
“Kiss me.” Kenma asked and pulled his face.
Kuroo’s in heaven. If that’s a dream, he doesn't want to ever wake up, he wants to spend eternity kissing Kenma’s sweet lips. One of Kenma’s hands lightly pulled his hair and the other scratched his back, while pulling him closer. Well, if Kenma’s the one pulling him, means that he wants Kuroo in his nest, so he did as he wishes.
Carefully climbed on top of him, trying to not mess with his nest and to not hurt him in the process. He felt the courage to explore his body too, slowly lowering his hand through the side of his body, squeezing his tiny waist. Kenma opened more of his legs to accommodate him and Kuroo could feel the heat between his legs, it’s almost driving him crazy.
Without stop kissing, he lowered his hand even more to pull the shirt and explore under it, feeling the smooth skin and earning a soft moan from Kenma. His heart could explode in his chest, but he wouldn’t stop for anything in this world, he just wanted to hear more of his moans.
He broke the kiss just to take off his shirt and look in his eyes again, to make sure that he could go on.
“Don’t stop.” Kenma asked, kissing his face and his neck.
He caressed the skin of his waist, hips, tights and squeezed his inner tight when Kenma bit one of his neck glands hard enough to leave a mark. He moaned together with Kenma when his hand reached his cunt, feeling how hot and wet he was. With one of his fingers he started to gently circle his clit and kissed him again, drinking his pretty moans.
“Harder and slower.” He asked, biting his earlobe.
He did as Kenma pleads, earning moans and more bites from him. Kuroo can smell his slick mixed with both of their scents, it's so damn good that his dick is getting painfully harder by every second. He wants to be inside Kenma, to feel him and to knot him, but wants to take his sweet time too, to give him so many orgasms that Kenma will begin to scream his name. He wants to devour Kenma entirely.
He kept moving his fingers as Kenma told him to, until his legs were trembling and he was whining and cumming just from getting his clit stimulated a little. Kuroo waited a few seconds before pushing one finger inside him, then another one, still trying to get used to these new experiences with Kenma. It's not an easy job to hold his alpha back, especially when his name sounds so beautifully in Kenma’s lips.
Every time he pushes his fingers inside him, Kenma leaves a new mark, by the time this ends, he’s sure that he’s gonna get trouble to hide all the bites and scratches, but he’s liking it a bit too much. Kuroo fucked him harder with his hands, the room was filled with wet sounds and his growls mixing with Kenma’s moans and whines.
He didn’t stop moving until Kenma’s legs were trembling and he was loudly moaning while cumming again. He looks so good like that, so hot. When Kenma looked at him again, Kuroo took his fingers out and licked it, aching to have a taste of him already, making him sigh looking at him.
“Alpha, aren’t you going to fuck me?” Kenma’s voice tone is so sweet, his words make his dick throb inside his pants.
“I want to taste you, princess.” His voice sounded deep even to his own ears, but it seemed that Kenma liked that.
“I like when you call me that and your voice sounds so hot, I can’t take it.” Kenma licked his neck again, lowering his hand until it reached Kuroo’s painful bulge. “I’ll sit in your face later, if you want, but I need you now.”
Kuroo kissed him again, rough and urgent just the way he liked it. The truth is that he’s not strong enough to say no to this. He’ll never be strong enough to say no to Kenma. He reached out to try to find the condoms in the bedside table, but Kenma stopped him.
“Don’t you want to knot me, alpha?”
“Yes, but if I do it you-”
“Do it. I’ll take everything you give me, my alpha.”
It looks like Kenma’s already lost in his heat lust, but after hearing Kenma calling him by “my alpha”, he broke completely. He couldn’t just deny this to his beautiful omega, could he?
Under Kenma’s gaze, he stood up to take off his pants and underwear, throwing aside before going back to his previous place. Kenma moaned just seeing his hard dick leaking precum already. He let him touch a little, sucking his breath when felt Kenma’s soft fingers around his cock. He could pop a knot just like that and that’s why he held Kenma’s hands, smiling when he pouted.
“I’ll let you do whatever you want later, kitten.” He promised, pulling him by his hips.
Kenma didn’t have time to complain about nothing before Kuroo started to tease him with the tip of his cock against his clit. He imagined a lot of scenarios in his head before, but nothing was even close to the real experience. The view of Kenma opening even more his legs to him, exposing shamelessly his glistening hot pussy was driving him insane. He’ll never forget that.
He started to slowly push his dick inside, never taking his eyes of Kenma’s stretching cunt, deliciously accommodating him and throbbing like crazy around him. Kenma loud moans filled the room as he bottomed out, cumming again just feeling his dick inside.
“God, you’re so good to me, my omega.” He praised, making Kenma whine. “You feel so good, baby.”
Kenma pulled him again and hugged his neck, locking his legs behind his back. Kuroo has no option but to start to move like that, doing his best with limited movements. Kenma was moaning the words “my alpha” in his ear nonstop, and this is getting closer to the edge faster than he would like to admit. His knot was already swelling and every time Kenma felt it, he cried out a new moan and a new plea.
“Can I bite you, alpha?” Kenma asked him.
“Sure, princess.” He doesn’t understand why he was asking this after so many bites already, but gave him more space anyway.
He just didn’t realize that the bite in question was a mating bite, he just felt the little fangs biting hard on his nape until it actually broke skin. Kuroo never felt anything like this, it was like fireworks were exploding behind his eyelids, waves and waves of pleasure shook his body while he popped a knot and cummed inside Kenma. The best feeling of his life.
It's not usual for the omega to be the first to give a mating bite, but it’s not impossible. It works the same for both ways.
After calming down from his climax, Kuroo started to gently kiss his face and lips, feeling happy about their new bond. Kenma seems happy too, even if they’re still locked together, he was purring and smiling.
“Are you okay?” Kuroo asked, slowly shifting their positions to lay on their sides.
“Better than never.” Kenma hugged him again, kissing his chest, above his heart.
“What about your heat?”
“I’m good for now.”
“Can I bite you too?”
“Yeah, you can bite me after I present to you tomorrow. I always get hornier on the second day.”
“God may help me, then.”
They stayed like that for a while, caressing each other, kissing and talking about what they just did and what could happen in the future. Kuroo feels incredibly calm, whatever happens from now he knows he’ll have his best friend and mate by his side. He can’t wait to spend every night like this, looking into Kenma’s shiny golden smiling eyes. He’s the luckiest man alive.
“Kuro.”
“Yes?”
“I love you too, my alpha.”
