Here's the final chapter to Science Can't Explain. I know it's an abrupt ending but I don't want to drag them or this plot into a way too complicated story to work with. Instead there will be a sequel that will continue on with Grimmjow and Neliel continuing this story after Neliel left Soul Society. There will be captains involved but it won't be these two anymore since it's not really in their nature for them to get involved too much into any problem unless ordered or absolutely necessary. Anyway if you have any suggestions for the pairing of the sequel I am open for suggestions.
Disclaimer: I don't own Bleach, obviously since this is "fanfiction" and not the actual plot of the manga/anime.
Warnings: Lemon from the Yaoi tree. I won't mark where it begins and where it ends because it's kinda all over the place.
"So it's been done?" Commander Yamamoto asked Kurotsuchi Mayuri as he presented to him a detailed report on everything the child had said and how she had been dealt with. "She's been disposed of?"
"Well I've killed her but I am using her body for further research on her kind, as you can see by the pictures I've already done some work on her." Mayuri said in a disinterested voice.
"Yes I can see that," the Commander said with mild disgust shutting the file, he looked back at Mayuri. "I know my decision to end her life was not taken kindly by both yourself and Captain Zaraki but both of you must understand the threat that the arrancars pose. It seems from the information she has given us that the remaining Espada is trying to reach Kurosaki Ichigo, if that is the case then we must increase the amount of guards we have since the boy to keep him safe. You are dismissed for now and well done."
"Thank you Commander." Mayuri did not feel guilty lying to his superior and frankly he was quite happy to be done with that whole ordeal, he was never one to mess in other people's business which was why he was glad to finally be done with it.
He had woken up that morning and after his cold shower he proceeded to aid Akon in adding the finishing touches to Neliel Tu Ordershvank's gigai that was then dissected and made to look like samples had been taken all in hopes that if the Commander had requested Unohana to check for authenticity they could try dissuade her from doing so. Thankfully it had not been necessary, the pictures he had taken and had added to the report had been enough proof for the old Commander.
He walked back to his division slowly taking in the bright sunny day. He had chosen not to wear his mask or anything extra other than his uniform and Captain's haori that day, he hadn't felt like it. Knowing that Zaraki was not going to be back for a few days, Mayuri made sure to keep himself occupied with new experiments and inventions enough to keep his thoughts in check.
The group had been sent to fake Karakura town for a whole week before being asked to returned after making sure that the hollows would not return. It seemed Nel had done her job well and reports coming from Urahara Kisuke informing Sereitei of the sightings of one so called Grimmjow Jaggerjaques had further clarified the reason why the hollows where no longer appearing on Soul Society grounds. Thankfully all reports coming from Urahara lacked any mention of a child arrancar, only that of a full grown female Arrancar that had helped him get rid of some hollows bothering Karakura town and was currently helping him investigate the recent attack on Ishida Uryuu aka "Quincy Boy".
The Captain's meeting that had taken place after their return had been brief and to the point both returning captains were tired and in the case of Zaraki annoyed and pissed by Kuchiki's incessant critic and overall attitude that whole week. Apparently Kuchiki had been standoffish and rude or rude-er than usual against Kenpachi culminating to the point of physically attacking each other causing further destruction of the fake town before the fight was broken up by the remainder of the group, particularly one Kusajishi Yachiru who did not approve of her "Ken-chan" beating the stuffing out of her "Byakuchi".
Mayuri could feel the exhaustion in Kenpachi's reiatsu so when the meeting was dismissed he turned to make his way back to his division alone but a hand on his shoulder stopped him.
"Hey, I'm back after a whole week and not even "hi" do I get from you. How mean," Kenpachi said his voice tired but managing to carry the humor in it.
"I figured you'd be to tired to catch up," Mayuri said as they walked side by side making their way out of the meeting hall and into the busy streets walking in the main direction towards both their compounds.
"I'm not tired enough to miss a chance to speak with you," the tall captain said smiling devilishly. "Besides, I keep my promises and I do recall I made one to you about what we would get to do after I return."
"Don't worry, you can keep it at a later time when you're not dead tire. After all, I don't want you falling asleep in the middle of it." Mayuri joked playfully pushing him on the shoulder.
"I'm sure I can rock your world even if I am this tired, besides I sure need to lift my damn mood after spending a whole week in the vicinity of the Kuchiki bitch." Kenpachi sighed rubbing his neck. "You don't know how much I missed ya while I had to deal with his constant insults making me want to tear him a new one every other minute. What is up with him anyway? We're not friends by any means but he wasn't this hostile before."
"Doesn't matter," Mayuri said frowning. He had kept checking up on the group throughout the week and had witnessed some of the fights between Kenpachi and Byakuya which had only served to further prove his assumptions that there was more to Kuchiki's insults that met the eye. Specially after said fights he would look more hurt than angry, and while some may argue that it was simply due to the harsh words the other threw back at him Mayuri was sure that was not the only reason.
"I guess, but you have to wander what crawled up his ass and died to make him so extra prissy."
"He's a snob, what do you want him to do? He's programed to make life a living hell for any person who does not share his noble status." They reached the 11th Division Compound. "Well this where I leave you."
"Nope, come on Kurotsuchi don't make me drink and sleep all on my own." He practically dragged Mayuri inside the division and towards his personal quarters, not that the scientist was putting much of a fight anyway. "Besides, I can't let you go anyway, not when you're looking so damn delectable today."
Mayuri blushed, he had been so excited about Kenpachi's return that he had completely bypassed his black and white mask he usually wore surprising the other captain's who had never seen him whitout it before. He had felt satisfaction at the look Byakuya had given him surprised by his appearance and by Kenpachi's lustful glance he'd sent his way.
"It was worth it just to see the looks of surprise from our fellow captains." Mayuri smiled mischievously, "it was as if they thought I was not even remotely human looking under my mask."
"No babe," the endearment earned him a punch in the shoulder which he ignored with a smirk. "It was the fact that they didn't think you were so damn beautiful under all that shit you wear."
"I'm not beautiful," Mayuri blush darkened nonetheless. "Men aren't beautiful, they're handsome."
"The point is that you're hot and that's why they stared." Kenpachi smiled down at Mayuri who returned it walking with renewed vigor and feeling happy at his companion's compliments making him blush lightly which made him look even more beautiful in Kenpachi's eyes.
The sun was still high in the sky when they made their way into the 11th Kenpachi's quarters and it was such a beautiful day that they decided to drink their sake outside on the porch sitting on the cool floorboards and looking at the garden that surrounded the property. It looked just like him, wild and full of life the trees and plants allowed to grow freely and all over the place.
"Yachiru planted them," Kenpachi said as he noticed Mayuri looking at the flowers that adorned the garden. "She just planted seeds everywhere she wanted and watered them daily until they grew this wild."
"It fits you both," Mayuri smiled lifting his cup to drink it's contents feeling the sake burn its way down his throat. "Where is she by the way?"
"Catching up with the presidential duties of her club and giving out the gifts she bought for them." Kenpachi chuckled with amusement. "She's an endless ball of energy."
"It's a good thing she's not here then," the scientist muttered refilling his cup. "She seems to be extremely curious about our... friendship."
"Is that all we are?" Kenpachi asked looking at Mayuri intently over the rim of his cup. "Just friends?"
"Well," Mayuri was lost for words the blush returning to his cheeks. "I suppose so... what would you say we are?"
"I would like to think that what we have is developing into something more than simply being friends with benefits."
"Friends with benefits?"
"Come on Mayuri, friends don't fuck each others brains out."
"I don't think that is physically possible but I get what you're trying to say." Mayuri pondered about his relationship with Kenpachi and he had to agree. "I agree we are more than friends...but then what exactly are we?"
"How about I give you time to think about it," Kenpachi drained his cup and laid down on his side placing his head on Mayuri's lap. The scientist began to thread his fingers mindlessly through his hair hearing the bells jingle as he moved them. "I have an idea of what we are but I rather you figure it out on your own. Think you can handle that?"
"That sounds good to me," he answered leaning down letting their noses touch but raised his head before he kissed the other captain, teasing him.
"Mayuri?"
"Mmm?"
"Did I mention how beautiful you are?"
"Pfft! Yes you did and like I said I ain't beautiful..."
"Yes, you are." Kenpachi lifted his head sitting back up before leaning forward towards Mayuri. "You might not want to believe me but it's true, and I have to say I am one lucky bastard to have you sitting in front of me like you are now. Though I have to admit I don't know why you ever let me touch you like you did. I am most definitely not a looker."
"Rubbish," Mayuri said feeling his blush intensify, he set his cup aside and lifted his hands cupping Kenpachi's cheeks. "You look perfectly fine from where I'm sitting."
He leaned the rest of the way needed to connect his lips with Kenpachi's immediately opening his mouth to delve his tongue into the other mouth moaning at the taste he had missed for a whole week. The sake bottle was soon forgotten as they engaged in more pleasurable activities. Since it was still early in the afternoon they made their way inside not wanting to be disrupted by unwanted visitors. They instead took their sake and climbed the stairs towards Kenpachi's bedroom lying down on a pile of cushions by the opened door that led to the balcony.
Mayuri ravaged Kenpachi's lips and mouth with his tongue as he laid over him. They tangled themselves completely with tongues, arms and legs in a fierce fight for dominance. They tore at each others clothes sending them flying in every direction as the rolled around the cushions kissing passionately once they'd rid themselves of all clothing.
"Did you miss me that much?" Kenpachi teased him as he nipped his way down his jaw and neck sucking on his pulse drawing a moan from Mayuri.
"I could ask you the same question," the bluenette countered not willing to answer truthfully. He raked his nails down Zaraki's back leaving marks behind that quickly healed. He began to lick and bite the scar that crossed Kenpachi's shoulder it had quickly become his favorite of all. He distracted Kenpachi by thrusting upwards grinding their groins together drawing a moan out of both.
"He he he, I have to admit I did miss your tight ass," the taller captain emphasized that by getting a hold on Mayuri's ass massaging in and pinching it slightly, lifting them to grind their hips tighter against one another. "I can't tell you how much I envied Ikkaku and Yumichika who sought out any opportunity to hump like rabbits whenever they could."
Mayuri chuckled though he was feeling elated at the captain's words. "And here I thought you must have gotten some with a whore of your old hometown."
"Hell no," he flipped them over Mayuri now on top who took the opportunity to sit up, feeling Kenpachi's cock snuggled in between his ass cheeks he proceeded to trace his hands all over Kenpachi's chest pinching his nipples and rolling them feeling the chest vibrate with a pleasured growl. "There's no one there or in Soul Society for that matter that can match you Mayuri."
"What about Byakuya?" Mayuri stopped all movement staring intently at Kenpachi trying to read any sign of deceit.
"Byakuya?" Kenpachi looked at him incredulously followed only by their panting as they stared at one another.
"Well?" Mayuri asked his nails beginning to bite down on the exposed flesh under them.
"What the hell does the ice queen have anything to do with this?" Kenpachi asked looking around as if expecting to see Byakuya standing there.
"Tell me; if Byakuya came to you and offered himself to you, would you choose him over me?" Mayuri asked holding his breath subconsciously.
"One: he would never do that..."
"What if he did?" Mayuri interrupted him exasperated.
"Don't get me wrong Mayuri, Byakuya is not bad on the eyes but... whoa hold on let me finish!"
Mayuri had gotten off his lap and had made to sit up when Kenpachi's hand stopped him pulling him back towards him grabbing his waist to keep a firm hold on him as the other struggled to free himself.
"Let me go!" Mayuri punched him in the face growling in anger. "He wants you, there I said it. So why don't you take your horny ass to his bed if you want him so much."
"I never said I did, so calm yourself down." Kenpachi went over the new information Mayuri had provided. "He wants me?"
Mayuri merely growled in response.
"Whether he does or not it matters little to me," Kenpachi grabbed Mayuri's chin forcing him to look him in the eye. "I am not interested in him, never was and never will, understood? I only have eyes for you. Now to answer your previous question: if he offered himself to me I would have refused him, no matter how good looking he is he does not have the personality to carry it and I am more interested in having a good time that how good the person besides me looks. You have are handsome Mayuri, and even though we've had our disagreements we get along fairly easy and that matters more to me in the end than your pretty face."
"I am not pretty dumbass, how many times do I have to tell you that?" Mayuri bit back but the heat was missing, he felt his chest loose the tight feeling that had constricted it making it hard to breath for him. He took a deep breath and without tearing his gaze from Kenpachi he leaned forward and pecked his lips. "I guess I'll believe you, though I am officially warning your ass to stay clear from him."
"Aye aye babe," Kenpachi mock-saluted him with a smirk on his lips. "Am I in the green zone now? 'Cause I am still horny as hell and wanna continue where we were."
Mayuri didn't answer instead he got on his lap straddling him and pressing their whole upper body tight together as he engaged him in a deep kiss entangling their tongues together seeking to dominate the other. Hands began to resume their exploration of each other desperately seeking sensitive spots to exploit. The need for words was no longer needed and unwanted both too desperate to stop anymore.
They broke their kissing when they ran out of breath panting harshly; Kenpachi began to kiss and nip on Mayuri's neck while grinding their hips together. Mayuri threaded his fingers through Kenpachi's hair, the bells had fallen out long ago during their rough play leaving the captain's hair to hang loose, he tightened his grip when he felt three fingers seek entrance into his mouth which he granted. He licked and suckled them getting them as wet as he could, lavishing them with his tongue.
Once he deemed them wet enough he allowed them to slip from his mouth feeling the cold trail they left as they worked their way down his spine and arrive at their intended target. He tried to relax as much as he could when he felt the fingers trace his entrance. Mayuri gasped softly as he felt the first finger breach him working its way inside and feeling his insides and thrusting into him to loosen him.
Once he grew accustomed to it Kenpachi introduced the next finger which did make Mayuri hiss in slight discomfort. Zaraki kissed his jaw and neck while his free hand stroke Mayuri's arousal trying to distract him from the feeling of being stretched after so long had passed since their last coupling. He scissored his fingers loosening him enough for the last finger, thrusting them as deep as they could go seeking out the special spot that would have Mayuri moaning for more. Once he found it, after feeling the walls around his fingers tighten and hearing the hum of pleasure from Mayuri, he pressed it a few times before deeming Mayuri ready for the next step.
He withdrew the fingers ignoring the moan of protest from Mayuri and the noise of disgust he made when Zaraki spat on his hand to use as lube for his own cock. He held on to Mayuri's hips encouraging him to sit up enough to align himself to his entrance, with a passionate kiss they became one as Mayuri sat back down slowly, impaling himself on Kenpachi's hardness moaning in pleasure even if he felt a sting of pain race through his spine.
The set a slow rhythm but their thrusts were deep and hard managing to stroke Mayuri's prostate with each thrust. Their bodies soon became slicked with sweat and saliva as they kissed an nipped any body part within their range, the only sound being the sound of flesh hitting flesh and pleasure noises that managed to escape from them.
"Faster," the scientist said hoarsely biting his lower lip as he tried to increase the pace himself.
"As you command," with that Kenpachi withdrew from Mayuri completely leaving him feeling rather empty. He pushed Mayuri encouraging him to lie on the pillows while he climbed over him supporting his weight in his arms so as to not crush the man below him and penetrated him in one push. The change of position allowed them to move faster, Mayuri left a trail of scratches down Kenpachi's back as the latter increased his pace striking his prostrate with every hit, he moaned Kenpachi's name biting his earlobe pleased by the hum of pleasure he was awarded with.
"Deeper... I'm almost there." He moved his hips in sync with Kenpachi's trying to get him to go deeper, he opened his legs wider and harshly grasped Kenpachi's ass pushing him against him with greater force arching in pure bliss as he felt his orgasm coming.
Kurotsuchi was not prepared to feel Zaraki's hand move in between their bodies stroking his erection moving his hand in rhythm to their thrusts. He felt his toes curl and the searing heat in his groin increase, Kenpachi felt this as well and their beat became even faster loosing all rhythm as they approached the end.
"Ah! Kenpachi!" Said man felt the walls around his dick constrict pulsing and drawing his own orgasm out of him. He came with a murmur of Mayuri's name kissing him deeply their tongues no longer fighting for dominance both content to just explore each others mouth lovingly. He rode out his orgasm feeling his seed coating the inside of the man who was humming in pleasure his own climax having spilled in both their stomachs leaving them feeling sticky but sated.
Both felt the taller captain's softening dick slip out of Mayuri with a wet pop as he got off him to lie by his side wrapping an arm around his waist.
"I'm glad to be back," Kenpachi murmured kissing Mayuri's forehead while the other threaded his fingers through his hair. "Even if you don't wanna admit that you missed me I know you did and so did I."
"Really?" The blue haired scientist asked with a lazy smile on his face kissing his lover when the other nodded in confirmation.
"Really," he kissed the blue hair smelling deeply to take in Mayuri's alluring scent. "I'm glad we helped protect Zaraki District but I'm glad to be back home where I belong now."
"Good, and I'm glad we're done with this business even though I know we have not heard the last of both Nel and that other Espada Grimmjow. I hate getting involved in business that does not concern me so if we ever meet another arrancar wandering the streets of Soul Society I vote we just kill them and be done with it." Mayuri said stretching out his arms before settling himself over Kenpachi's chest resting his head on his chest. "I like my life to be interesting yes, but not that exhaustively so."
"You didn't do much of this before did you?" He said emphasizing his question by squeezing the buttocks resting on top of him. "Do you regret it?"
"Not at all," Mayuri answered smiling at Kenpachi before grinding his growing arousal against Kenpachi's. "Though I still haven't found the reason why. I did some test on myself but all came out normal and I couldn't even make myself kiss someone else to see if it was just with you, the thought of kissing someone else sickened me."
Kenpachi chuckled amused by the antics of his "friend" noting with satisfaction the others unwillingness to connect with others as he had with him. "Babe there's some things even science can't explain."
"I beg to differ," the scientist in him refused that explanation but then again maybe just this once. "But for now I will admit the results were inconclusive and let it go at that."
"Has your scientist mind came up with a label for us yet?"
"From my observations on our interactions and those of others who have similar relationships with other people the only thing I can compare our relationship to is that of 'lovers'. Do you agree?"
"Yeah that sounds about right." Kenpachi smiled caressing the others back feeling the scars on his back from various surgeries the scientist inflicted upon himself. He chuckled, unbelievable, of all the people to end up with it had to be a sadistic mad scientist. Then again, he never did like that useless thing called sanity having none of it himself. Curiously enough they matched perfectly to each other even if they did fight quite a bit the make up sex was great and the knowledge that they would get over their little fights was enough to make the relationship worth it.
He ceased all thoughts as he felt a finger flick him in the forehead bringing him out of his thoughts and back to his surroundings the first thing seeing was his crazy scientist straddling his hips enticingly.
"I hate being ignored Ken," Mayuri smiled wickedly. "Besides your brain is not accustomed to think too much, it'll overheat."
"Ha, ha." Kenpachi growled though with no real heat to it. "Why don't we stop here then, that poor little, mind though toned, body of yours is not accustomed to be overused, it might overheat."
"Isn't that the point my simple minded lover," the word sounded sexy coming from Mayuri's mouth even if it was accompanied by an insult. "Now let's get that heat going shall we?"
"Can't say no to that."
The world beyond the walls of the 11th Division Captain's Quarters continued on in their daily activities, most of them unaware of the Captains' absences and the ones that did noticed knew better than to go look for them.
After that day, Mayuri never once did resume any testing on himself to find the reason for his attraction to the other captain. He no longer wanted to nor cared if there really was a scientific reason for it, having found himself smiling and enjoying his days more than he ever had in all of his life. As for Kenpachi he had finally found a person who could handle being around him and that could manage his temper and was happy to have him by his side. Even if sometimes that someone might try to convince him to be a test subject for him once in a while.
~~The End~~
How was it dear readers? Did it suck? You can go ahead and criticize my horrible attempt at a more detailed lemon, after all I'm still learning and any help will be most welcomed.
Thank you for reading my story, I know it's no work of art but it was a good attempt and I gave it my all. I hope you enjoyed it!
