Alpha Kaito x omega shinichi

Shinichi knows that Kaito wants children, you just have to look at how happy and excited he becomes when he shows magic tricks for them, how he showed them one miracle after another.

Shinichi also knows how good of a father Kaito could be, and he is having a hard time thinking about anything else but that for a while now.

Kaito has been away for 1 week for a show in a town over. Shinichi's heat has not started since he turned back and that put the organization down, actually, it's been 3 years. AI have told him it's probably because of all the stress his body has been put through, that his heat has been put on hold for his body to recover.

He did not mind it that much tbh, its easier to work when he doesn't have to think about suppressants and heats all the time. A year after, the organisation was put down. Kaito Kid found and destroyed Pandora, after his heist he walked up to Shinichi with a rose and told him his real name.

It’s a good memory for the both of them, Kaito has told him that he could not tell his name before he found Pandora, for his safety of course. Not that Shinichi really minded, he had already known his name but did not seek him out because of respekt for his wishes.

But right now, They have been dating for 2 years but still haven't mated, because shinichi's heat haven't come yet, shinichi have helped Kaito thought his ruts and always came out of it with bite marks on his neck, but they always heal after some days, much to Kaitos displeasure. Kaito knows of the reason and The whole Conan fiasko. He never pushes him about mating but they know they both want it.

But for the last week Shinichi has been feeling weird, it started when Kaito helped a young girl at one of Shinichi's crime scenes, she could not stop crying and Kaito walked up to her, showed her magic tricks and made her laugh. Something in shinichi clicked then, it was a rush in his body he had not felt in a long time.

He is now sitting at home, and looking up baby things, beds to feeding bottles. He can't stop thinking about having kids with Kaito! He has been making mental lists of what a Child might need. Maybe he is starting to become crazy, he is also starting to become more sensitive, crying while watching shows about babies.

His body has also started to change, he thinks and feels. His hips have become bigger and his nipples is becoming more sensitive. He almost thinks he may be pregnant but that can’t be, he still hasn't had his heat yet! And he doesn’t really feel pregnant, he thinks and rubs his belly, feeling a flash of sadness.

He should really have a talk with AI.
_—------

Okey so he should maybe freak out, the talk went well and she thinks that his heat is beginning to come, by all the symptoms means it may even come today or tomorrow.
The trouble is that Kaito is having a magic show a town over and doesn't know this!

Shinichi doesn't really feel prepared for this, but at the same time, finally being mated to Kaito is a thing he has wanted for a long time, finally bonding completely to each other sound really exciting. Shinichi thinks as the absent mindedly started to feel hot and rub his thigh together.

Like in a trance he wobbled into his and Kaitos shared bedroom. He opened their closet and took almost everything, just clothes that smell the strongest of him and Kaito. He also took a box from deep in the closet. Inside is one of Kids suits with his cloak. He pressed it to his face and breathed in Kaitos Alpha scent and felt how a shiver went through him and how he started to feel really hot.

Shinichi threw everything on the bed and rearrange it so everything would be perfect, he threw of his clothes that he had on him and noticed that his underwear it drenched in slick, his pussy was really wet and all that he could think of was Kaito and his knot, about his strong alpha mating and breeding him.
The next thing Shinichi noticed was that he had in his mental fantasy crawled in under all of the clothes on the bed and was sniffin one of Kaitos shirts that his alpha had slept in recently. He felt really horry now, he had a safe nest and his alphas smell wherever he turned, he reached with the hand that was not pressing Kaitos shirt, into his underwear.

He tugged at his cock a few times before sliding his finger gently over his balls and finally his cunt, his finger went in easily with all slick that he already produced. A loud moan escaped his lips and his whole body shaked, his fingers pumped in and out from his pussy and his other hand on his sensitive nipples.
It wasn’t long before his hips chased his own fingers, moans and whimpers fell from his lips and his body shaked. He felt good and felt his orgasm was near but something was missing, Kaitos face flashed in his mind. That’s it, he needs his alpha and mate here! Sure his nest smelled of them both but kaito wasn't here.

But that did not stop him, his hips hade a mind of his own and continued to push down on his fingers. He whimpers and roll into his stomach, that made his neglected cock rub against the sheets and made him welp. He continued to rub his overly sensitive penis against the sheets while his hips pushed into his fingers, and his fingers pressed right against a sensitive place and made him come. He moaned loudly while his pussy contracted around his fingers and gushes out slick and his cock shot out strings of cum on the sheets.

He collapsed into the bed and tried to catch his breath, he felt more tired then satisfied now that he hade came once. His body still felt hot but is more bearable now.
He looked his nest and took Kaitos kid mantel and wrapped around himself, he missed kaito really much now and wanted him to touch and mate him.

But Shinichi's peace did not last long before another wave of his heat clouded his mind and now felt more painful with his missing love, he buried his body under all the clothes and tried not to cry for his alpha.
—--------------
It was around midnight when Kaito came home, after his magic show they hade a efter party that he attended but he went home as early that he could.
He signed as he took of his shoes and loosen his tie.

“I'm home” he whispered out into the dark house, he was sure that shinichi was already asleep so he did not expect an answer. As he walked up the stairs to their room did he noticed a strong smell, it smelled of lemon and honey and it was really strong. Before kaito could really think he stood In front of their door, it was a little open and he could almost see all the pheromones flowing from the room.
He gently pushed open the door and put his hand on his mouth suddenly when he was overwhelmed by the smell, he could feel how his body was getting aroused and how his cock was twitching.

He looked on the bed and noticed that it was almost a mountain of sheets and clothes. His eyes followed the trail from the bed to their closet that was open.
Approaching the bed he lifted a couple sheets and saw something that made his heart jump out of his chest, in the pille of clothes was his sweet shinichi, he was hugging Kaitos pillow and absentmindedly humping at it in his sleep.

Kaito could only think of one thing and that was that his shin-chan had finally gone into heat! He wasted no time in stripping out of his suit and gently climbed into the bed, into his omegas nest.

He laid next to shinichi and gently brushed hair out of his face. Shinichi started to stir and opened his eyes slowly, he looked at kaito and pushed closer to him.

“kai…” he breathed out ragged and lopped his arms around kaito that immediately placed his hands on his hip and face.

“shhh I know, I’m here now love” he answered back and rubbed his thumb over his cheek and his other hand slides to his detective's backside. Shinichi felt his body getting hotter and his pussy producing more slick, he pushed kaito into his back and climbed up to sit on his lap.

“Kaito help me” he breathed out and slides his slick cunt over Kaitos hard cock. “I want your knot Kai! I want you to breed me and fill me up with your seeds!” he said a little louder and went faster with his hips.

Kaitos' eyes darkened and he rolled them over so Shinichi was under him. He kissed his omega deeply and pushed his tongue in his mouth and shinichi moaned, shinichi spread his legs so kaito could get in-between them.

“Don’t worry my sweet omega, I’m gonna knot you so much that I guarantee that we have pups after this” kaito said after kissing shinichi's lips red and now kissing his neck and suckling dark marks over his neck and chest. Shinichi’s mind went hazy with want and spread his legs more slick almost flowed freely out of him.

“Yes please Kai get me pregnant! I want your pups in me, I want to bond with you” he cries out with his hands sliding in Kaitos hair while kaito sucked on this nipples and rolled the other one.

Kaito took his Shin-chan's word to Heart and kissed and licked down Shinichi's chest and stomach and finally down to his crotch. He kissed down his hips and into his inner thighs, avoiding his leaking cock. Shinichi was moaning in pleasure and fisting the sheets over his head.

Kaito licked a small lick against Shinichi's pussy.

“aaaaahhhh” shinichi screams out in pleasure while kaito pressed his omegas thigh up into his stomach so his pretty wet pink cunt was on full display. He wasted no more time before diving down in to the pussy. He licked his pussy, trusting in and out while sometimes sliding his tongue up to his clit, making shinichi shake in pleasure.
It did not take long for Shinichi to cum from his alphas talented tongue, he had Kaitos head in his hand and grinded tha last waves of his orgasm against his tongue. He collapsed down on the bed after his orgasm and kaito just licked his lip, smirking.

“You taste so good my Love , but now it’s time for what you've been waiting for, hand and knees love~” kaito said while rubbing his cock and visible knot.
Shinichi slowly rolled into his stomach and slowly rised to his knees but did not have the energy to lift his torso. He looked back at his alpha and wiggled his hips to entice his alpha.

Kaito lost it seeing his shin-chan so horny, pussy out and leaking cock right in front of him. He pounced on shinichi and rubbed his cock up against him while his arm looped around shinichi, shinichi looked at kaito and begged him to fuck him. Kaito kissed him and finally slides home.

“Aaaahhhh” moans out loud when he felt his cunt stretched to Kaitos cock, his cock came to a stop when it pressed against his womb and knot got in.

“Ha…you feel so good Shinichi, like your hole was made for me” kaito said against shinichi ear making him shiver. He did not move yet, making Shinichi impatient.

“aahh come on Kai! Fuck me already!” shinichi said pushing his hips against kaito making his cock grind deeper. Kaito place his hand on his omegas hips and trusted once, making shinichi cry out.

“As you wish love~” Kaito breathed out and started at a rough pace. He took almost his whole cock out before trusting back in. Shinichi could only hold on from how hard the trust was, his mind was getting more foggy. He could only think of Kaito and having his knot tying them together.

Kaito continued to trust his cock in and out, he was now mounting shinichi and was kissing marks on his Mate's neck, he found his scent glands. His hands were everywhere on shinichi s body rubbing and pinching his sensitive areas. His hand came to one of his nipples and ran his thumb over it, and noticed that Shin's nipples had gotten bigger.

"Where are your nipples always this big?" Kaito said more to himself than to anyone, Shinichi who was drowning in pleasure heard it anyway and blushed all the way to his chest. He got even more horny thinking about them growing even bigger to produce milk. His pussy got even tighter and that made kaito growl, keeping his cock in his tight pussy feeling it pulsate around him.
After a while Shinichi grew restless and moved his hips to feel Kaitos cock move inside him.

"Come on Kai! Move please, I want your pups!" Shin said in a breathless command, he tightened his cunt more to make Kaito react. And react he did, moving his hips away to slam his whole cock back in and making his omega moan.

"You really want to? Huh? Having your belly grow heavy while carrying my children?" Kaito said and moved his hand to stroke Shinichi's lower stomach, thinking about his Shin-chan having his big belly and leaking nipples made him more aroused.

"Y-yes I want it, it's all I could think about this last month" Shinichi said while looking kaito in the eyes. Seeing that his Shin-chan was serious, his heat clouded eyes looked more clear than before. He took his love's bigger hips and pounded his cunt harder and faster. Shinichi could only hold on into his nest and take it.

"I'm gonna knot you now baby, you gonna look so pretty pregnant" kaito growl and started to roll his hips more for his knot to slip in. Chanting 'yes yes yes' over and over again Shinichi felt how the knot was growing inside and he was crying when it finally popped in and Kaito bit his neck, the biggest orgasm he ever felt nearly made him faint, he still pushed back against his alpha keeping his cock close to his womb as his seed started to spurt inside.

Kairo moved them both to lay on their side, spooning while being connected and spurting hot cum inside his Shin-chan's womb, hand resting on his stomach.

"Love you so much," Kaito said as he licked his mating bite on Shinichi's neck, nuzzling his shoulder.

"Love you to" Shinichi, whose heat finally was taken care of, replied sleepily. Moving his hand to place on Kaitos, he was slowly falling asleep, dreaming about his babies and loving mate.
