"Why don't you call me by my first name, huh, Moyashi?" Kanda asked calmly to Allen.

They were in bed naked. They just had sex. It had been six months that they were married and it was Allen's heat. His heat happened every three months and longed for five days which was really inconvenient. Indeed, every three months for ten days, Kanda and him would be unavailable for any missions. Just when Akuma activities were increasing lastly. Sometimes Allen wished he wasn't an omega. If his heat weren't that disabling, he could go on missions when he is needed. It was so disheartening. Plus, he was the only omega exorcist. So, his friends wouldn't understand.

The only good thing about his heat was he and his husband, Allen always blushed whenever he described Kanda as his spouse, were talking a lot about things they wouldn't talk usually.

"If you call me by my name then I will call you by your first name, Bakanda" Allen said sarcastically.

"Tch, you know that you are Kanda, now right?" Kanda said followed by a smirk.

Allen stuck his tongue and confessed that he would eventually call him by his first name one day but it was awkward for him to consider Kanda as his husband. It embarrassed him for now. But for the time being, he would call him Kanda.

"You're blushing, Moyashi" Kanda teased and received a pillow in his face followed by a glare from Allen, "Oh come on, don't be mad at me, I find it cute you know" Kanda added.

"I am not CUTE" Allen said half-heartedly feigning anger but his blush just made him unconvincing and really cute. Allen loved how Kanda was when they were alone and intimate. Kanda was less cold and wasn't short-tempered. Just when he thought of how adorable Kanda could be, he found himself being topped by the said-person. The older one hips were above his and their chest were only one inch far away. He felt hot and never in his life he hadn't been more attracted to Kanda. The Japanese held both of his hands and came closer to his face. At first, he thought he'd kiss him.

"You know that you're still blushing right?" Kanda whispered in his ear with a very sexy voice.

Allen gulped, they just had sex ten minutes ago. He was turned on by Kanda's voice, how Kanda's hot breath brushed past his ear it made him shiver. He couldn't help but took the man above him abruptly and kissed him.

"Knot in me, Yu" he moaned between the kiss.

Kanda was surprised by the outburst and smirked. He pulled off from the kiss.

"Already horny, Moyashi" he started "you know I can't refuse anything if you talk like that, Allen" he continued. He kissed his neck knowing that it was Allen's weak point. Then the British found himself moaning each time Kanda kiss every inch of his body or when he sucked his left nipple or when he started to lick his penis. 'Ah he is so appetizing' he thought.

"Ahhhhh, Yu" he begged almost desperately when Kanda started to stroke his already erected penis. He had goosebumps everywhere. "Pleaseeee, fucking hurry"

The kendoka knew what he meant and teased "Impatient, Moyashi?". He knew that Moyashi wanted him into him. He loved the younger heat. His pheromones and scents were completely hypnotizing. They were in their own scent cocoon and it was close to heaven. This little guy below really drove him crazy and he couldn't help but felt genuinely happy. He didn't regret coming back to the Black Order. On the contrary, he would bitterly regret if he hadn't come back and save him. Now he was having sex with the one that he once disliked. His feelings changed a lot. In this fated mission, in Italy, he'd never been so touched by anyone after his second life. However, he would never admit it but when the little guy did everything in his power to fulfill Lara and Guzol promises he impressed him. That was why he protected him from the Akuma fatal blow when the younger one collapsed due to his innocence modified form side effects. But he had to put away his feeling at that time because he was looking for her. Never had he thought that it was the omega he was attracted to that would help him with Alma. He was selfless and didn't give up on Alma. Saying goodbye to Alma was his most precious moment and it was thanks to Allen.

It was absolutely his favorite view. Viewing Allen naked with a blush on his face and begging for him to knot in him was totally his favorite view. In that state, Allen was so docile. When they were having sex in normal day, Allen wasn't this docile. He was very combative after all and they would always fight for dominance even though he was an omega. He loved that Allen's side too. The omega topped him once as an experience but they didn't enjoy it that much. It wasn't that bad but it wasn't that good for the alpha. He felt pleasure but it didn't really feel like heaven. And the omega wouldn't really fully feel pleasure when his "clitoris" (A/N: Omega males have something similar to clitoris in their anus. Its function brings pleasure to the male.) wasn't penetrated. Since they didn't enjoy it, they wouldn't try it again. However, before the penetration, they would still fight for dominance until Allen was penetrated.

"I'll start with one" he firmly said. Allen seemed to understand and changed his position to let the other man penetrate his hole.

Kanda was about to insert his finger but before that he teased the other male first by stroking the entry. Upon hearing, Allen's plea for the umpteenth time oh god he loved this voice he finally inserted it softly making the other one moaning.

"You are so wet, Allen" he said while moving his finger inside the omega. He moved slowly at first and then as Allen's moan was slightly louder than before he moved faster and faster. He then inserted another finger after a moment startling the other one. Like earlier he was moving slowly and then faster and deeper. When he thought the omega was ready to be penetrated and knotted, he asked "You ready?". The other one nodded and he smirked. He started to thrust his penis inside Allen which made the other one scream.

They started to move their hips.

-o-o-o-o-o-o-o-o-o-o-o-o-o-o-

Kanda was the first one to wake up. After he knotted with his husband, they decided to take shower together to save water and eventually had sex in the process. When they were clean, they decided to sleep. They were both tired after three rounds almost in a row. He observed his omega while he was still deeply sleeping. He looked literally like an angel. His white hair, his pale skin and his soft feature combined made him look angelic and innocent. The room was warm and filled with their mixed-odors and mixed-pheromones, it was really pleasant. He really appreciated Allen's heat.

However, he knew Allen hated his heat because they wouldn't go in mission. That guy was still obsessed with akumas. Well he would never understand him because he didn't have a cursed eye that allowed him to see akuma's soul. But he heard that Lavi experienced this particular power one time and couldn't eat for days. Whatever. It didn't matter anyway. He would still love the Moyashi heat no matter what.

Also, the church forbade the use of heat suppressant. 'Those fucking conventional people'. Because it was not "ethical". They didn't even have access to pills to prevent pregnancies. Allen was beyond afraid of getting pregnant but Johnny assured him that the medicine Allen took every day had some contraceptive effect. So, they could have sex safely during heat.

Kanda didn't mind having a child though. But they couldn't because they were exorcists. And if they were having a child, during this was it would be dangerous. Their enemies could use their child as hostage to set trap and it was out of question. If this fucking war was over, he wished to have a little child. His own child.

He was beyond worried for this little guy and it was so unlike him but he couldn't help it. He loved him and cared for him. He would never show his worries in front of the other one though.

The Science Department found a way to delay the Fourteenth take over by creating a special medicine that Allen took every day. It was good news. But he knew deep inside that one day it wouldn't be efficient anymore. He was afraid of that. They were still working on it. It'd been two years that they were trying to find a solution and they still didn't find any clue. It also didn't help that Central was always behind their back especially Lvellier. 'Tch' he thought. He had feeling that this annoying man did want the Fourteenth to swallow Allen, it had no proof but his guts told him to be wary of the said man. He didn't know what the older alpha was up to but he wouldn't let him do whatever he was intended to. It was his duty as husband and Alpha to protect his Omega.

He was brought to reality when the white haired shifted in the bed. Kanda thought at first that he was waking up but he just changed position still with his peaceful face. He could watch him like that all his life he wouldn't get bored. The omega looked at peace the alpha was sure he was having a nice dream. He smiled at the thought recalling the day he came back to the black order.

-o-o-o-o-o-o-o-o-o-o-o-o-o-o-

"Allen heat is over" Matrona, the head nurse, announced to everyone. "He can have visits now but he still needs some rest. Since he doesn't have an alpha, the heat wasn't too painful and unbearable" she added.

The inspector Howard Link nodded and was heading to the room where the omega was. Kanda followed him and when the other alpha was about to retort he informed him the Central decision regarding the Moyashi. Link raised his eyebrow looking skeptical and distrustful but he surrendered anyway.

"I will go first then." The inspector said "I am going to unrelease the binds and then you may enter"

"Tch" was all Kanda said. He didn't need the inspector to give him order. But he agreed nonetheless.

When Link got out of the infirmary room, they nodded at each other. But before leaving, the crow said that he was going to release Timcanpy as well.

When Kanda saw the other alpha retreat in a good distance, he entered the room and went towards the teenager's infirmary bed. The other one didn't notice at first that someone had entered the room. He was sited in his bed, rubbing mindlessly his left arm, glancing the outside world through the window. The new headquarters was more luminous than the former one. They were a lot of window making the Black Order look less gloomy and depressing.

"Oi, Moyashi." he greeted with his usual cold voice which startled the other one.

Allen stopped rubbing his left arm, mouth opened, wide-eyed and was turning to him. He couldn't believe it. It was that man voice. The voice he thought he would never hear again.

"K- K- K- Kanda?" he stuttered and then he slapped hard his own face in a desperate attempt to wake up. But he wasn't dreaming. He was definitely awake. The slight pain he felt in his cheek was a proof. It was really Kanda. Still he didn't believe his eyes.

They were staring at each other. Not moving, not saying a word, silence filled the room.

Kanda reached for his swollen cheek. He was interrupted by Allen's hand who slapped his hand away before reaching for it. He looked angry.

"Kanda… I really don't get you" he said angrily "I am really happy that you're alive but what about Alma?" he continued breathlessly.

He gripped tightly the sheet covering his legs. He gritted his teeth.

"Weren't the two of you finally free?" he almost shouted.

"Despite that… Why…" he started to ask. "Why are you wearing the order's clothes?" he looked at him for answer, his tone was still filled with anger.

He raised his voice and screamed "WHY ARE YOU THROWING AWAY YOUR HARD-WON FREEDOM?".

Kanda grabbed his tee shirt and pulled him closer to his face. Their faces were very close to each other making the omega blush. Kanda was glaring to him and if glare could kill then the white haired would be dead right away.

Kanda started to say staring at the ground "Even if it's you…" he gritted his teeth and tightened his grip "I swore I'd take this to my deathbed without telling a single soul. Those last moments with Alma belonged to me and me alone" he softened his gaze and now was facing the beansprout but his face still looked grumpy "You gave it to us that's the very proof that me and him are free"

Allen looked surprised and then started to cry mumbling "Alma" again and again.

'He started to cry?' Kanda thought and released his grip.

-o-o-o-o-o-o-o-o-o-o-o-o-o-o-

"What are you thinking, Kanda?" Kanda looked at the one who spoke. The beansprout woke up and seemed to be awake for a long time.

"Tch, not your business" he replied sarcastically.

Allen pouted and teased "Of course it is, aren't we married?". He smiled evilly like almost like when he was playing at cards.

"If you call me by my first name, then I'll tell you" Kanda said with a slight smile on his face. Allen knew it that Kanda rarely smiled like this. It was a sincere smile. A smile from the heart.

He didn't know why but he was on the verge to cry. The tears were welling up in his eyes. Not understanding anything, the alpha reached for his right cheek and caressed it tenderly.

"Why are you crying, stupid Moyashi?" he asked "You're such a cry baby"

In a normal time, Allen would have complained for being called "Cry baby" but instead he placed his hand above Kanda's. He squeezed it delicately and return the Japanese's smile with a very warm smile. A sincere smile.

After a long moment, Kanda being patient and not talkative, he finally spoke "I like it when you smile like that, Kanda" he blushed "It is discreet yet so radiant and warm that it reaches your eyes. I love it when you redirected this smile to me. It makes me feel good"

Kanda didn't say anything. He just closed the gap between him and his spouse. And kissed his forehead. Allen was completely red and when the older one approached his ear once again; he was literally like a tomato. "Only for you, Moyashi. And …" the Japanese whispered and started to wipe off his tears.

"And?" Allen asked curious. His husband didn't continue his sentence.

"Nah nothing" he nonchalantly said while getting up looking in the other direction. Then he turned to him. "You're just so beautiful when you blush like that and with those tears pearl sticking in your eyes." Allen couldn't believe his eyes, Kanda complimented him and he was slightly blushing too. "Also, your smell is so good when you're sincere like that" the older one added.

Tears started to flow again and he thought that it was okay for him to be happy. He was so stupidly happy just by hearing those words from his stupid husband. It was okay to make room for his heart. Mana and Kanda could share his thoughts after all. He felt something warm enveloping his body. Kanda hugged him and grungily said "Stop crying you idiot or else I am going to cut you with Mugen". He slightly laughed and kindly scolded the other one "Stop solving every problem with your sword, Bakanda". He started to surround his stupid Kanda with his arms. He pulled him even closer than they already were.

They stayed like that for a long time. In a tight hug. Breathing each other scent. No words needed to be said. They were enjoying each other's company.

The Japanese was the first one to break the silence.

"In case, you haven't understood" he pulled out from the embrace to stare at Allen's eyes "I allow you to call me." he said and added upon seeing the other confused looks "Call me Yu".

Allen smiled and reassured him that he would call him by his first name sometimes. He wasn't just ready yet. Kanda reluctantly agreed and threatened him to shave his hair if he wouldn't do it anytime soon.

The omega laughed and promised him.

"You better keep your promise, baka Moyashi "he poked the other one forehead making the other one complained that he kept treating him like a kid.

They bickered for a while before having another round of sex.

"I hope that it isn't too good to be true" Allen said after their umpteenth round of sex. They were sweating trying to catch their breath. He mostly said it to himself. He had feeling that something was going to happen. Everything was going smoothly well recently. It was too odd. He couldn't tell what but he had bad premonition. It was what his guts were telling him.

"Mmh" was all the kendoka reply. Truth to be told, he was thoughtful too. It was awkward but he felt the same way. They were bound to each other after all. Sometimes it happened that they were in symbiose.

"I am going to take a shower" the white haired sighed "Being always horny is so annoying."

"I don't mind" the dark haired said and smirked. He avoided a pillow thrown at him and his smirk widened when he heard "You are just a PERVERT".

The cursed man entered the shower. Kanda stayed in bed. He wanted to take shower with the omega. However, he was preoccupied by what the other one stated earlier.

He was really starting to worry about him. He really hoped that everything would be alright. They just had to keep walking. Kanda laughed. Never had he thought he would say the same stupid thing as his stupid spouse. It was ridiculous.

He just didn't want to lose him at any cost.

He would do anything to save him.

He would do anything to protect his smile.

He promised to himself that no matter what he would be by his side, would protect him and would prevent him from being swallowed by Nea. He wouldn't give up on him like he did with Alma.

Little did they know what would happen in the next months.

Any thoughts?

I will do better sex scene next time lol. I will focus on Yullen moments at first but don't worry the other characters will be included later on.

Any reviews?
