In a world where Demons had become domesticated in the last century or so, becoming glorified pets and workers.

You knew you had done your friend a favor by getting her a pet demon, especially since you were worried about her mental state, which had been rapidly getting worse.

Weeks and months had passed now. Of course you remained in constant contact and had observed how good it was for her to take care of the demonic creature. Which of course left you wondering why you didn't have one, since you weren't any better when it came to fighting the loneliness that was a constant part of your life. Some solitude was always good but when prolonged, it was overwhelming and could be painful.

That's why you thought it couldn't hurt to - maybe - keep your eyes open, look and behold, it literally popped in front of your nose as you walked past a shelter. There was a red sign with 'HIGH DISCOUNT' there.

It wouldn't hurt to take a look, right?

Your entrance was announced by the ringing of a bell above the door. There was no one there and you looked around cautiously. There were all sorts of things that were used for keeping a demon. You walked down the corridor and saw a big cage standing darkly in the corner. It was larger than the other cages you had seen and you became curious, especially since the sign also said high discount.

As you walked in closer, you noticed the demon who was on his knees behind the bars, dignified and humble, he had his gaze lowered until he realized you were there. He was beautiful with his maroon colored eyes and long black hair that turned reddish at the tips. A prominent mark on his forehead took nothing away from his beauty and neither did the two horns that protruded from his forehead. Two horns…? Wait a minute, this means…

“This is a pureblood, very rare on the market.”

Startled, you turned to the clerk, who suddenly stood behind the counter and stared at you. Your gaze went back to the demon, who looked at you carefully and didn't take his eyes off of you. “Then why is it at such a low price?”

“Because of his brother.”

"His brother?" You frowned and looked confused from the seller to the cage and you felt another presence in the cage - 6 glowing eyes stared at you from the dark corner.

He stepped forward next to his brother and even though you could tell they were probably twins, you could clearly see the differences. The red of his long hair was darker and more spikier, his complexion paler, his physique was broader and more muscular. But this was not the main difference. It was his eyes which he held 6 pairs of. Golden with red sclera. His aura was intimidating and yet also very regal and proud. He had two horns as well that were more purple than red. He also adorned an additional mark that ran from his chin down to his throat.

“Why, what’s wrong with his brother?” You couldn't take your eyes off him as you asked your questions and saw him squinting all of his 6 eyes on you.

“Yoriichi is a very domestic and remarkable demon. Very trusting, friendly, and listens to every command but his brother, Kokushibo, on the other hand… Well, I can only say that his previous owner was not able to handle him.”

“It didn’t occur to you to separate the two?”

“Of course, but every time they were separated, Kokushibo became more and more uncontrolled, and Yoriichi always managed to escape and return to his brother. We’ve tried it several times but it just didn’t work, which is why these rare purebloods are on discount.”

You saw Yoriichi looking at you with interest and Kokushibo about to hiss at you. You turned your head to the seller and grinned at him. “I’ll take them both.”

~ ~ ~

You really didn't know what got into you when you found yourself standing in front of the two demons that were clearly too tall. They literally towered over you by almost two heads, looking down at your pathetic height. You should have been intimidated, but strangely enough, you weren't. Maybe it was because Yoriichi's calm and tranquil manner balanced out Kokushibo's wild and angry one. The two of them were like yin and yang. Brothers who couldn't be separated.

The purchase was so spontaneous that you weren't really prepared and you were lucky enough to have a larger apartment with an additional room that you could possibly make available to the two of them. Your friend, whom you surprised with the demon Giyuu, probably felt as unprepared as you too.

“When was the last time you two ate?”

The two of them stared at you before Kokushibo turned away in disdain and Yoriichi felt obligated to answer for them both. He opened his mouth and it was the first time either of them had opened their mouths. “We last ate 10 days ago.”

What?! No wonder the six-eyed demon was in such a bad mood. Demons didn't have to eat regularly like humans. 1 to 2 a week was enough, but not 10 days! They must have been absolutely starving!

After they had eaten, you prepared their room. Unfortunately you didn't have any other beds, just futons, but that should be enough for now.

~ ~ ~

A few days passed and they were quieter than expected. Kokushibo hadn't done anything bad to you but still refused to talk to you while Yoriichi was very pleasant.

“Yoriichi, do you want me to take your collar off? The Wisteria pouch must be uncomfortable for you.” Collars were mandatory for demons when they wanted to go outside, but the owner was able to choose at home.

He lowered his gaze humbly. “You are too kind, Mistress.”

You were very fond of Yoriichi. You liked his kind and gentle nature that even soothed your own chaotic thoughts. It was the least you could do for him. You asked him to lower his head and carefully took off his collar. While you came so close to him, you noticed his hair and gently stroked it. “How about I brush your hair, it’s looking a bit dull.”

His hair was beautiful and you could feel how he enjoyed being pampered by you in this way. How your brush went slowly through the dark red waves, making them shine again. It was a very domestic situation between the both of you that got interrupted by a dark aura from the corner. You quickly glanced from Yoriichi’s hair to Kokushibo. If you didn't know any better then you would assume that he was jealous, but you were not sure.

“Are you hungry?” But there was no answer. It was not like you expected him to talk. Both demon brothers had been very silent since the beginning. After taking off Yoriichi’s collar you noticed that he spoke a little bit more. His pleasant and calm voice relaxed you deeply and you wondered whether Kokushibo could even speak and whether it was perhaps because of the prong collar that he still had around his neck. The prong collar looked painful and even if you weren't intimidated by his strong presence, you still wanted to be careful.

But somehow that seemed unfair to you.

“Yoriichi, please wait here.” You stood up and approached the tall menacing demon until you were standing in front of him. He didn’t lower his ominous presence when he looked down on you and yet you showed no fear. ”Lower your head, please.” But he did nothing of that sort, but squinted his 6 eyes onto you. You let out a long sigh. You knew that it wouldn't be easy with him and yet you were slightly annoyed when you needed to pull up a chair so you could be on the same level as him.

“Don’t move…” You were very close to him as you fumbled with his prong collar to open it. What kind of brutal device was that? The collar was far too tight on his neck and had left scars; there were also scratch marks that showed that he had desperately tried to open it himself. It was said that demons who have face marks are wilder and less easy to tame. Kokushibo even had two. Was that the reason why they tortured him like that? Anger flared up in you, but you took controlled breaths so you were able to focus on this damn opening mechanism.

Kokushibo watched your efforts with interest and for the first time there was no anger or threatening aura coming from him or his eyes. After some fiddling with his neck, you managed to open the damn collar and threw it on the floor. Your gaze was focused on the puncture scars on his neck. Without a second thought, your fingers roamed over the spots.

Well at least you tried, because he had stopped you with such a quick movement that you took a startled step back. The only thing was that you had forgotten you were still standing on a chair and your foot stepped on thin air.

Everything happened so quickly in the next few seconds that you were not able to realize what actually happened until your body was pressed against his, his strong arms around your waist. He caught you in time and held you against his solid physique, and you could feel how strong and muscular he was. You looked at him with wide eyes while he looked at you almost bored. “You humans are so clumsy.”

Were those really his first words towards you? His voice had a deeper timbre than Yoriichi's and it made your skin shiver. Since his arrival, all he had done was glare at you and intimidate you with his brutal presence, which he was very good at controlling. All that was gone now as he still held you close to him - as if you weighed nothing. His gaze on you was interested, since this was the first time you were up so close to him.

“You- You can put me down now…” And he did. With a gentleness you never expected from him. Your soft body slid along his. You looked at him, slightly puzzled. “I'll get some balm for your wounds. Maybe you should sit down so I don’t have to get back on a chair.” He just nodded at you and sat down on the sofa where Yoriichi was sitting.

You left the room briefly and didn't notice how the brothers communicated with each other or how Kokushibo’s eyes were following you. With the balm in your hand, you sat between the two and turned your attention to Kokushibo. “Don’t be alarmed, it might be a little cool now,” you whispered as you gently rubbed the cool gel along his neck. He didn't even bat an eyelash and just let you do it while keeping all his 6 eyes closed. Was he enjoying it? It seemed like it. You carefully stroked over it a second time as you saw how the wounds were already starting to heal. “Woah!” You let out surprise.

“Our wounds heal very quickly and we can’t have scars, but my brother's collar was coated with an extra strong dose of wisteria that made him even weaker and made it difficult for him to speak. Thank you, Mistress, for this generous gift you gave to both of us.”

Yoriichi, who was sitting to your right, had taken your hand. He brought it gently to face and brushed it against his cheek and gave each knuckle a kiss. There were so many emotions associated with his gesture, like gratitude and affection, that it almost brought tears to your eyes.

You turned your head towards Kokushibo who looked at you with a look that you couldn't interpret. He finally spoke and his voice made you shiver again. “I would like to take a bath. May I, Owner?”

You simply nodded and watched him get up and disappear into the bathroom. Yoriichi, who was still holding your hand, spoke as his brother was gone. “Michikatsu is not evil as anyone would assume. He needs love and affection like any other being. I wouldn't mind if you would give some of your attention and affection to him."

“Michikatsu? His name is not Kokushibo?”

He shook his head. “Koku, black. Shi, death, Bo, eye. They named him like that because of his eyes. He never corrected them as he wanted them to fear him. But in reality Michikatsu is the nicest of them all.”

Michikatsu is the nicest of them all.

Yoriichi's words echoed in your mind as you knocked on your bathroom door and opened a crack. "Can I come in?"

“This is your house, Owner...”

You grimaced at his wording and entered anyway. You saw him sitting relaxed in the tub with all but one of his eyes closed. With the one he watched you carefully as you took a washcloth and sat down on a stool behind him. You gestured for him to lean forward slightly, which he did.

You moistened the washcloth with the warm water and gently slid it over his broad shoulder. Luckily his hair was already in a bun so you had free access to his back. At first he was very tense, but when he realized that you didn't mean him any harm and just wanted to scrub his back, you felt his muscles slowly relax under your fingers.

“I told your brother the same, please don’t call me Owner. Just call me Y/N. It feels so degrading to you both to call me owner.”

He was silent for a while before answering. “We... are demons... We have no right to name anything the way we want... We have no right to have an opinion on what we should be called. We are just objects in people's eyes. Easy pets...”

This time you were the one who remained silent, because you had felt the resentment and frustration behind those words. You took a cup and filled it with warm water and poured it over his back to wash away the dirt that had formed from your scrubbing. “I don’t know what your previous owners did to you. You don't have to tell me, but you're not objects to me. You are living beings who deserve to live a good life. You can call my home yours too. You are allowed to have possessions too.”

“That is…noted…”

The next few minutes were shrouded in silence, but it wasn't unpleasant. On the contrary, Michikatsu actually seemed to enjoy the way you gently massaged his scalp with your fingertips while you shampooed his hair. You enjoyed these domestic activities. To take care of someone. To make them feel good. You hadn't done that for a very long time because you had also been alone for a long time. Being alone was painful-

Before you could delve into your dark thoughts, you noticed an odd smell and was startled. Did you leave something on the stove? No, it smelled way too pleasant for that.

Michikatsu noticed your twitch, but he didn't react like you. “Yoriichi has been watching you for days, like me. He’ll probably cook you something while you’re here with me.”

You looked at him in surprise. He wasn't serious, was he? You really wanted to check, but wanted to finish bathing Michikatsu.

“Go… I’ll wash up and join you…”

You nodded and walked into the kitchen where you saw Yoriichi standing at the stove with your pink apron on. He looked at you and gave you a smile. “Since you take such good care of us, I wanted to prepare something for you. I read that miso soup is very popular and you had the ingredients for it. Do you like miso soup with silken tofu?”

You couldn't help but giggle at the sight of him looking so adorable with your pink apron. “Yes, I love miso soup.”

~ ~ ~

Ever since Kokushibo spoke to you, you were sure that all three of you were getting along very well. You ate together, laughed and talked. Well mainly you talked, because the two of them enjoyed listening to you talk and you finally had the feeling that someone actually wanted to listen to you too. And of course you cared for them too. Pampered them, washed their backs and bought them what they wanted even if that was not much. Yoriichi had once told you that it was enough that you would treat them well as you did now. This always made you question what terrible things had been done to them. How would they dare to treat them badly? You didn't want to think too deeply about it. If they didn’t want to talk and think about it then who were you to do so?

“Ouch!”

You looked at your finger which was starting to bleed. You quickly put your bleeding finger under running water to rinse out the dirt and checked out the wound. Shit, the cut was deeper than expected. Suddenly you felt Michikatsu’s presence very close to you. You jumped. Even after weeks, you couldn't get used to how quietly the two of them moved around the apartment. He looked down at you and your bleeding finger.

“Don’t worry, it’ll stop bleeding soon.” You weren't sure if you were saying this more to yourself than to him, but he wasn't deterred. He took your hand and put your finger in his mouth, licking the blood off. You looked at him with wide eyes. You were even more surprised when he suddenly took you in his arms and carried you to the couch and sat down, you sitting sideways on his lap, taking your bleeding finger into his mouth again.

You were literally puzzled, but he didn't seem to mind. You had been in the middle of cooking and wanted to tell him so, but he just gave you a look which silenced you.

“Clumsy human, let Yoriichi do the cooking and let me take care of your wound.”

You wanted to say something in response but didn't know what. You had already seen Yoriichi scurrying into the kitchen but were distracted again when Michikatsu gently nibbled on your finger and put it in his mouth.

Since that time he always looked for moments to distract himself by nibbling on your fingers. He seemed to have an oral fixation, or he just liked it. Either way, he seemed to be enjoying it and it didn't bother you, so you let him have his way. It also gave you the chance to look at him up close, as he often didn't allow that.

Michikatsu noticed this of course. “You’re not at all disgusted by my appearance.”

“Why should I?” You did not understand the question.

“Are my eyes not too scary for you?”

Oh, this is what it was about… “Is this why you always keep all eyes closed and just look with one?”

“No, I keep them closed so that I don’t have sensory overload and… so that you aren’t afraid of me.”

“So I was right?”

He kept silent and you gave him a soft smile. “Please close your eyes.” He did as you asked. You moved closer to him ever so slowly and gently kissed each of his 6 eyelids. When you let go he looked at you in surprise, his 6 eyes wide. This was the first time you could see the emotions so strong on his face. “You are not a monster and never will be to me.”

~ ~ ~

“You are not jealous, right?” you asked Yoriichi, while he was sitting patiently in front of you as you brushed his long beautiful hair.

He shook his head. “No, why should I?”

“Well… Because I give your brother so much more attention than you.” It was a little bit uncomfortable to admit this, but it was true. Michikatsu was very demanding and jealous from time to time, even if you don’t give him much reason for it. But yet, anytime you were close to Yoriichi or spending time with him, he immediately snatched you away in silence and nibbled on your fingers.

“But I did ask you to do so, right?”

“I mean, yes you did. But I still feel bad about it. You deserve my attention as much as Michikatsu.”

Yoriichi took your hand, it seemed like the brothers had a fixation with your hands, and kissed your knuckles as he always does when he wants to show his gratitude. “Sitting here with you, hearing you talk, while you touch me so affectionately, is everything I ever wanted.”

Yoriichi were always able to hit you with the right words and gestures. You leaned forward and gave him a kiss on the crown of his head. “You are such a good boy and deserve the whole world.” You felt Yoriichi shiver from your words.

~ ~ ~

Months passed, the season changed and it was winter. That meant the Christmas markets opened very soon! You were excited because you wanted to show the brothers how beautiful the markets can be. Of course they needed to wear collars, since demon companions were required to wear one by law. You hated it, since you were not able to forget the painful device Michikatsu had had to wear, but you had to adhere to the law. You decided to get the type that was demon friendly without the wisteria pouch for both of them.

The three of you strolled through the Christmas market, Michikatsu to your left and Yoriichi to your right, and you received a lot of attention. You didn't know if it was because of their height or because of their distinguishing face marks. It could also be due to Michikatsu’s threatening aura, or the fact that they had two horns which identified them as purebloods - a very rare sight to see.

It wasn't important to you. The only important thing was that they had fun like you did and got as many impressions as possible. You curiously looked at all the stands and came across a woodcarver that had beautiful pieces to offer when you suddenly saw a wooden puzzle box. Himitsu-bako. You took it carefully and stared at it, fascinated. You always wanted to try it. The idea to get so fixated with a riddle was so appealing to you that you asked about the price. He named the price. You thanked him, placing the puzzle back down, and went to the next stall.

“Why didn’t you buy the puzzle box? You seemed very interested in it.” Yoriichi looked at you questioningly, while Michikatsu lingered in the back, his attention somewhere else.

“Oh, it was a bit too expensive. I wanted to have money for candied apples and to buy you two something you want! The puzzle has no priority.” You gave him a bright smile as the cold air made your cheeks blush.

You threw yourself onto your couch immediately when you got home. Man, you were exhausted. Yoriichi and Michikatsu didn't even seem to show any signs of exhaustion, but you clearly were. Walking for hours had drained you and you just wanted to relax now. “Do you want to watch a movie?”

As usual, they sat down on the couch on either side of you as you made yourself comfortable. It wasn’t long until your head was resting on Yoriichi's lap, him playing softly with your hair while Michikatsu massaged your calves that were sore from all the walking. You felt so comfortable and safe that it didn't take long for you to fall asleep and you missed over half of the movie. You didn’t notice how Yoriichi gently lifted you into his arms and carried you to bed or how he gave you a gentle kiss on the forehead while you cuddled yourself onto your blanket.

~ ~ ~

"What is this?" You stared at the small box that was placed in front of you and you didn't hesitate to pick up. It didn't take long for you to realize what it was. It was a wooden puzzle box. Himitsu-baku! You looked excitedly at the beautiful piece. “But where did you get that from, Michi-kun?”

“Michikatsu is very skilled in wood carving,” Yoriichi replied as Michikatsu watched you with interest. “He made me a flute too, see?” He took out the little flute and showed it to you.

You looked at the beautiful piece in awe and then looked over at Michikatsu. “Michi-kun, I didn’t know you were so talented! Yori-kun, can you play on that?”

Yoriichi didn't hesitate and played some soft tunes. You clapped your hands enthusiastically. “You two are so talented!” You watched as Michikatsu turned away and hid his face behind his hair. Was he blushing? You probably saw it wrong… You looked back at your box. These were some refined skills, which made you wonder.

“It never occurred to me to ask you about your hobbies or what activities you like to do…” You felt guilty because until now they had always obediently gone along with everything you wanted but you never asked what they wanted.

The brothers looked at each other, visibly confused by your change of topic. This time Michikatsu spoke to answer your question. “We enjoy…training kendo together… But our previous owners didn’t like it at all… They got scared… Also we always lack the space and the necessary tools.”

"Tools?"

“A bokken, but a simple wooden broomstick will do too,” Yoriichi explained to her.

"Oh! I think I can organize that! Also a place for you to train! The apartment complex has an unused backyard. We can go there in the evening! As often as you want too!”

You three were at the said place. You were not able to find a bokken, but Yoriichi had said that broomsticks are enough for now. You can get them the necessary equipment later. Oh, how happy they would be, you thought excitedly to yourself.

Now you sat in a corner, lulled in your jacket as you watched the two brothers standing in front of each other. They first bowed respectfully and then it began. Their movements were so fluid and elegant that you were barely able to look away. It was a dance between two brothers who couldn't be more different. Like the sun and moon, Yin and yang. You weren't sure who would emerge victorious, but you were still surprised to see Michikatsu a few minutes later on the ground.

Another fight. Michikatsu was on the ground again. It went on like this until the yukatas were thrown over their shoulders, hanging down from the Hakamas. They were both suddenly topless, the cold didn't seem to bother them. You felt heat creeping into you. It wasn't like you'd never seen them topless before, since you washed and bathed them both from time to time. But now they are training. The muscles rippled in harmony with their movements, it was only then that you realized how incredibly sexy they both actually were.

Both were muscular and strongly built. Yoriichi a little leaner than Michikatsu. Your eyes wandered and you couldn't get enough of what was presented in front of you. Wandering up and down until they stopped on the seductive V-line of the two of them. Your eyes switched back and forth and you had to suppress a sigh as Michikatsu lunged forward, flexing his big biceps.

It didn't take long for you to get wet and dampen your panties. Crap. That was not good. You couldn’t be horny for your demons! That's irresponsible! Both of them had immediately stopped and stared at you as if they knew something. You blushed like a tomato.

“It seems like Y/N is cold. We should go home,” Yoriichi said as he put his yukata back on.

Michikatsu nodded and did the same and you were happy that demons were not able to notice things like that, right?

~ ~ ~

You laid in bed, frustrated, not being able to finish what you had started. Fuck, why can’t I come already? For the past hour you were touching yourself, trying to get rid of this horniness and the lewd thoughts that bothered you all evening. But it didn't work!

You huffed, frustrated, pulling your hands from your pants, and rested your arm on your forehead. It has been a while since you touched yourself. Was it possible to unlearn things like that? You didn’t know. What you did know was that you were exhausted and wanted to sleep but the hot images of the two brothers haunted you badly.

Your thoughts were interrupted by soft knocking. “May we come in?” It was Yoriichi’s soft voice.

You immediately gathered yourself and sat straight in your bed. “Um, y-yes, sure!” The door opened slowly and the two brothers entered your bedroom. “Were you both not able to sleep?”

No answer, only gazes as Michikatsu sat down at the end of your bed and gently massaged your calves while Yoriichi sat close to you and held your hands in his. Normally you didn't have a problem with them being so touchy, you were happy to give them whatever they wanted and secretly you enjoyed it too, but at the moment it wasn't so good. Because you were a bit oversensitive due to your frustration.

Yoriichi looked at you with his soft maroon eyes as he cupped your face. “We sensed your troubles.”

Your furrowed your eyebrows. “My troubles?”

Michikatsu’s hands were gliding a little bit higher onto your thigh. “Yes, your arousal.”

You didn’t know if you were blushing because of the embarrassment of being caught or the feeling of his hands being so close to your core. It also didn’t help that Yoriichi lowered his head closer to your face and talked in his soft beguiling voice. “There is no need to be ashamed, Y/N. You always make sure that we feel good. You care about us so much, never seeing a monster in us. We want to give it back to you…” With each word he came closer, until his lips were on yours. His kiss was so soft and loving that you sighed into the kiss. Yoriichi took that as an invitation for his tongue.

While Yoriichi distracted you with his sensual kiss, you felt Michikatsu slowly dragging your pants along with your underwear down and spreading your legs. “Brother, she smells so intoxicating…” You felt his breath close to your pussy.

Yoriichi, who let go of you briefly to let you catch a breath, answered his brother. “Her lips are sweeter than anything I’ve tasted before.”

Michikatsu did not wait and licked at your slick like a hungry cat and groaned. “You are right… She tastes like heaven…” With these words he dove into your core and lavished on your juices. You let out a surprised moan as you threw your head back. Your hand grabbed desperately at Yoriichi’s yukata who just watched you, fascinated, and then kissed you again. But he didn’t stay on your lips for long. His mouth traveled down your neck, nibbling at the soft skin there. You felt how his hands were slowly pushing up your loose shirt to cup one of your boobs and massaging it slowly with one hand. His mouth also found his destination and kissed and sucked on your other nipple.

So many sensations at the same time and you were not sure what to focus on. The knot inside you tightened, and suddenly everything exploded. You came with a loud moan as you threw your head back once again.

Michikatsu’s lower eyes were closed, his face glistening in your juices. He pushed a single finger into you just to let Yoriichi lick it off. You watched the interaction between them both. It was like he wanted him to know how you tasted. You saw how Yoriichi’s pupils dilated as he tasted your sweet nectar. It was such a lewd image that it made you sigh in anticipation.

You heard your bedsheet ruffle and watched as the brothers swapped their places. Suddenly Michikatsu was in your face, kissing you greedily on the mouth, not letting you take a breath. You were able to taste yourself on his lips but you didn’t mind it at all. Not even that he used his teeth, because all of that was washed away by Yoriichi's tongue and mouth, who was now the one eating you out.

There was a clear difference between the two. Yoriichi was definitely gentler, as were the tongue strokes along your outer labia. Or the way he sucked on your clit. Your left hand was on his head, tangled into his soft waves as you pushed him closer to your cunt, feeling how close you were again.

Your other hand was on Michikatsu, who was pinching your nipples, making you wince and twitch every time, forcing you to keep your attention on him. It was a lot to handle. Lots of feelings and desires at once that you didn't know how to deal with. But they were so strong, able to hold you still while they feasted on you.

Yoriichi hit a point with his tongue that made you come with a loud cry. The waves of the orgasm were so intense that it left you trembling. You had never cum twice in a row in your life.

Yoriichi wiped his face with the back of his hand. Both brothers watched you in awe as you layed there, exhausted from your orgasm.

“She is so beautiful… I want to mark her.”

“Later, when we are inside of her.”

“I am not sure if her bed is able to carry us three.”

“Yes, we should move her to our room with the futons.”

You were not able to distinguish who said what, since your brain felt like mush, but that was not important. You were suddenly lifted up and carried by someone. Your cheek resting on a strong chest. You realized that you were all naked. When did they undress you? You opened your eyes slowly to see his beautiful maroon eyes. “Yori-kun…”

You felt his lips on your forehead and then on your lips again, making you sigh again and heating up the desire in your lower belly.

“Do you think she can take us both?

“She is stronger than you think.”

“I know.” These two words were said in such loving affection that it made your heart flutter.

“Hey… I am still here,” you protested. “You both prepped me so well I… I think I can handle that.”

"Oh, you do?” The first time in your life you saw how Michikatsu smirked at you as he snatched you away from Yoriichi and sat you down on his lap.

You felt his hardened cock close to your core, but your eyes were fixated on that smirk of his. He was “...gorgeous…” You leaned forward, your hands on his muscular chest as you kissed him oh so softly. It seemed like he didn’t expect that softness. Never did he expect anything, though he deserved all the softness and kindness.

You poured all your love into the kiss, playing with his hair, nudging his tongue against yours and biting at his lower lip. He groaned and got impatient. He picked you up by your thighs and placed you on the tip of his dick and let you sink down very slowly. “Michi..!” You whimpered and shuddered at the fullness and how good it felt.

He bottomed out and didn’t move, letting you adjust. Until you moved your hips. “Impatient human,” he murmured as he started sucking on your tit.

You didn't stay still though as you slowly moved your hips and started riding him. His hands grabbed your thighs tightly to help you. Michikatsu couldn’t help but sigh at the feeling of your tightness around him. Gosh, it felt so good hearing those noises coming out of him, knowing that you were the cause of it. Making you feel that you had a tiny bit of control even if it was not like that at all.

Suddenly you felt his hands on your waist, moving up to cup your breasts and kneading them; you also felt his lips kissing along your spine, making you shiver as you still moved on top of Michikatsu. You smiled and when his kisses reached your shoulder, you tried to turn your head to look at him, to give him a kiss. Yoriichi came closer but you were interrupted by Michikatsu, who grabbed your chin and turned your head back to him, just to claim your lips harshly and groan into the kiss.

“H-Hey-” you panted after he left you breathless. “Stop being jealous. I want to kiss Yoriichi too!”

Michikatsu was about to respond when Yoriichi picked you up into his arms without warning. With one fluid movement Michikatsu’s dick slid out of you and you could only go “Oh!” at the sudden feeling of emptiness. Even Michikatsu breathed out harshly at the sudden change and glared at you both.

“Now it's my turn.” You giggled at him teasing his brother and slung your arms over Yoriichi’s neck, your legs around his waist. It was clear that he missed your kisses and you were glad to give him all he could ever want. You started kissing him all over his face - his cheek, his nose, his eyes, and then his lips. You both couldn’t hold back moaning into the kiss when he suddenly sheathed himself into you. You at the fullness he was giving you, and him because you were so tight around his cock.

You marveled at his strength as he held you up so easily, starting to move inside of you at a slow pace. You felt safe in his arms; you knew he wouldn’t even think of dropping you.

You felt the jealous glare on your back and it didn’t take long until Michikatsu got up to stand behind you. One of his hands pushed your hair aside so he was able to kiss and nibble on your left shoulder. You felt his chest pressed on your back as his fingers slid up to spread your wetness and lube you up with additional saliva. It was a strange feeling, but not unwelcome, as Yoriichi’s careful thrusts distracted you from Michikatsu’s motions behind you.

Soon enough, he retracted his fingers and replaced them with his tip. He was so careful with you - a contrast to his earlier roughness - moving in tandem with Yoriichi to bring you pleasure rather than pain. The feeling of them both inside you was overwhelming and you didn’t know what else to do other than to hold tightly onto Yoriichi’s shoulder, your nails digging into his skin.

Michikatsu’s hands joined Yoriichi’s on your thighs. It felt as if the heat of their touch burned you to the core and even if you wanted to get out, it was impossible. You were placed so tightly between the two brothers, moving in sync into you, you could not move at all.

One of your hands reached behind you so you could grab onto Michikatsu’s neck. The other one still gripping onto Yoriichi. The angle changed, and you saw stars, clenching tightly around both of them making them both groan. They sped up, the pleasure bringing tears to your eyes.

“Please…!” You begged, not knowing what for, but it seemed like they knew.

You were not sure if you saw it correctly as your brain was not able to comprehend anything logical at that moment but you saw a change in Yoriichi’s face as if he was communicating with his brother.

The knot inside you tightened for the third time that night. You cried out their names as they thrusted harder into you making your vision blur. This time your release was more intense than you’d ever experienced, but before it could ebb away you felt teeth on both of your shoulders.

You could only cry out and everything went black.

~ ~ ~

Ah shit... Why does my shoulder hurt so much?

You woke up between two muscle-bound bodies and didn't know where you were until you remembered the last night. “Oh fuck…” you whispered and immediately put your hand over your mouth when someone started to grumble in annoyance. Did you wake one of them? Suddenly you were pulled by a strong hand and pressed against a muscular chest. “Stop thinking too much, human, sleep a little bit more. You need rest.”

You looked up into the face of Michikatsu, who had narrowed one of his lower eyes to look at you. You couldn't contradict him because you felt tiredness overcoming you again and you fell back into a deep sleep, safe in his arms.

You woke up again, but this time on Yoriichi's chest, who was playing with your hair. “Good morning.”

“Good morning…” You yawned and looked around, realizing that you both were alone on the futons. “Where is Michikatsu…?”

“He is preparing a bath for you. How do you feel?” He watched you as he waited for your answer.

How did you feel? You were not sure if you thought about last night. Did you regret it? No… But your shoulders were killing you. “My shoulders hurt and I feel sore, but that’s it.”

“Oh, that’s because we marked you.”

“Marked me?”

“Yes,” he smiled at you, “We are now mates.”

Mates… Wait what?! Was that even possible between a human and demons? You heard about this rumour that demons were able to mate each other, but fuck… This was the last thing you ever expected. “What will happen now?”

“First of all you are going to take a bath while we take care of you.” Michikatsu appeared at the door frame as he looked at the both of you, laying naked on top of each other.

~ ~ ~

Even if it was weird in the beginning you quickly got used to the idea of being mated to both of your demons. You hadn’t been sure what to do with the situation and called your friend, who just told you that she had also got mated with her demon. It was not a common thing at all, actually unheard of, but here you were, having not one but two demon mates.

You asked them if that was something common, to have two demons, but they shook their heads. “It’s probably because we are twins and very attached to each other. Perhaps it was inevitable we would share a mate,” Yoriichi told you, while he nuzzled his face into your hair.

“Who would have thought that we would mate with a clumsy human?” You saw the smirk on Michikatsu’s face that now happened to appear more after that night. He seated himself next to you both and snatched you away from Yoriichi again. It seemed like a game between the two brothers at this point - as if they were not able to share a toy.

You faux-sulked. You just took his face into your hands and gave him a long loving kiss. Then you felt how he placed something on your lap.

It was a wooden carving of a woman with two tall men at her sides and looking closer, you realized it was the three of you. The gift nearly made you spill tears, touched by his gesture of love.

Ooo the hantengu clones in heat. Especially karaku... the poor babies

Sekido

He's miserable, and not doing anything to help himself. Sekido absolutely despises everything his body is trying to do. The sudden sensitivity and urges to seek comfort are humiliating, and worse, they make him much too vulnerable. Finding some isolated corner to hide in doesn't make anything better for himself, though, nor does snarling at anyone who gets near him. It's an ordeal just to get Sekido to let you sit nearby, and he's resisting any of your attempts "help" like he thinks you're trying to trick him.

A lot of the cause for this is that he hurts. When he's this sensitive, all of his old, poorly healed wounds and self-induced stress aches go from unpleasant to agonizing, and that makes Sekido desperately defensive. He instinctively fears being hurt while he's like this, while he's unable to defend himself properly... even though the slightest relief would have him melting in seconds.

Karaku

Heats make him desperate, to the point where his usual pleasure-seeking behavior turns frantic. When he feels like this, Karaku would do anything to avoid pain or discomfort. He wants to be held and touched and treated softly so badly it hurts, but that's not an option. It's never been an option, outside of when humans had another use for him that he could be rewarded for. He's pliant enough that he won't lash out even if you approach him, too limp and uncomfortable to do anything but accept what happens.

Any kind of touch you offer is highly effective. Effective in the sense that Karaku's brain shuts off even more than usual. He can't remember why he shouldn't just crawl halfway into your lap and press his face against your shirt until everything stops feeling so awful. There's not a thought left in his head about the possibility of being hurt— just desperation for anything that feels good.

Aizetsu

As soon as he starts feeling weird, Aizetsu tries to hide. After spending so long contained with the other three and their more violent habits, his instinctive response to feeling vulnerable is to avoid any unwanted attention for fear of it turning violent. Regardless of if it's comfortable or not, he's curled up in the smallest, darkest place he can find, muffling sobs into his hands because every part of him feels wrong. The oversensitivity makes his usually fragile emotional state much, much worse.

The combination of fear, stress, and his body's overreaction to every stimuli makes him actually sick, more often than not. Aizetsu is prone to being affected by his emotional state anyway; like this it only gets worse. Even though he knows that proper care would make him feel vastly better, he's stuck in a miserable state of believing he deserves to suffer through the heat alone.

Urogi

Heats wreck his energy levels, making him lethargic, dazed, and barely aware of what's going on around him. Instead of constantly fidgeting and moving around, Urogi can barely get himself to sit up on his own. The most reaction you'll get out of him, most of the time, is twitching wings and maybe a miserable whine. He wants attention so badly when he's like this, anything so he's not just lying there and spacing out for hours at a time— it's unnerving for time to disappear like it does when his brain is barely functional.

He's too weak and limp to lash out at you, though so it's safe to get close. With his whole body oversensitive and so very responsive to anything that feels good, any kind of petting results in whimpers and full-body trembling as it gets even harder to think clearly. Especially when that restless energy shifts into arousal, he's soon desperate for more and more of your touch.

This fic is,,, weird. But I enjoyed writing it. I still feel slightly embarrassed posting it however lol

Root idea inspired by phantasmiafxndom

Cw for mentions of child abuse *cough cough* Shinjuro

☆.。.:・°☆.。.:・°☆.。.:・°☆.。.:・°☆

Demons, in their current form, were not just disgusting to Kyojuro but also pathetic in a way that made his heart burn with anger. Decades ago it had been perfectly fine to kill them. The creatures were a scar upon humanity and extermination was agreed upon by nearly everyone.

Now people treated them like a nuisance at worst, some even tended to coddle them. Protests grew daily, demanding the demons be treated more humanely. Humanely? For creatures that used to eat humans, still did in some cases. It was a fate kinder than they deserved.

Despite Kyojuro’s distaste most people didn’t share his feelings on the matter. Perhaps the most upsetting was the fact that Senjuro had complete adoration for demons. He tried his best to tolerate his brothers ideas, but couldn’t often hide his disturbance.

It only got worse when a few of Senjuro’s schoolmates got demons of their own. They had become a new fad, and the ultimate status symbol. Why have a dog or cat when instead you could find a demon who you could dress up with hair to brush.

Even his own brother cooed over the creatures. One or two of his classmates (alongside a few of Kyojuro’s own students) sported such popular pets and enjoyed showing them off. During lunch students would gather around pictures to oo and ah over whatever unique features the particular example had.

And while Rengoku worked a humble job as a teacher, their father still had plenty of money to spare even after retirement, something his younger brother was well aware of. It was no surprise when Senjuro too started to beg for a pet. The man was less secretive of his distaste inside his own home. He wasn’t harsh or cruel with the boy, simply firm. Senjuro had asked for pets before. This obsession would fade much like rest.

—-

Six months later Kyojuro gave in. Senjuro had earned some sort of reward. The elder brother didn’t like to leave the home often, not for elongated periods of time. Shinjuro mostly kept to himself now but it wasn’t impossible for their father to lash out. These incidents were few and far between. The only connection between them was that they occurred when Kyojuro wasn’t in the home.

But he had a job to do. Volunteering for an overnight field trip had perhaps been a mistake on his own part. In the past Senjuro had been able to find appropriate accommodations for the night or two his brother was gone. This time it was simply a combination of all the wrong things coming together.

He shouldn’t have believed his younger brother’s insistences that everything would be ok. Uzui or Sanemi would loathe watching the children but he could’ve forced one of the other men to take his place. That didn’t change the fact that he was the one who left on the trip. Everything on his end went rather smoothly. The children were rowdy, but didn’t cause any major problems. After constantly checking in and several reassurances from Senjuro he pushed his worries to the back of his mind.

They rushed forward again when Kyojuro arrived home. Even upon his return his brother greeted him with a smile and warm hug. It would’ve been a nice welcome under most circumstances. Senjuro wore a high collar, creeping above his neck. It wasn’t entirely inappropriate for the weather but wasn’t part of his typical ensemble.

Rengoku went to pull at the turtleneck. Though the boy nervously tried to avoid the attempts it wasn’t as if he could run away.

“It’s fine aniue,” he mumbled. Kyojuro saw a purple spot forming. It wasn’t too large, not the largest Senjuro or himself had ever recieved, but still there nonetheless. Softly he brushed the area with his thumb. His younger brother let out a little puff of air despite his attempts to hold in any reaction.

Finally allowed to pull away he backs up. Already his eyes are clouding with tears. Kyojuro waits for a moment, gently reaching his hand out so it barely hovers above the boy’s shoulder. When Senjuro leans into the touch he’s quickly smothered in an overbearing hug. He doesn’t quite sob, but tears soak into the elder brother’s shirt.

Even though Senjuro is mature (which sometimes makes Rengoku guilty in a way, because he shouldn’t have to be so mature) he’s still fourteen. Beyond that he’ll always be the younger of the two. Kyojuro had gotten used to sharing a bed and taking care of a sick brother and buying birthday gifts the moment their mother died, when Senjuro had barely started school. It feels natural to pick him up and settle on one of the softer couches. He’s small enough to still be able to curl up in Rengoku’s lap.

The two are happy to sit there for awhile. Senjuro was never much of a talker so the man doesn’t push him for now. Tears roll down his cheeks, which Rengoku swears still carry a bit of baby fat.

“I’m sorry I shouldn’t have left. I’ll be more careful next time. You didn’t-“

“It’s not your fault aniue. F-father just- he got mad because I dropped a plate and it’s fine. I don’t wanna talk about it anymore.” More water wells up in the corner of his eyes. After sucking in a shuddering breath he tries again. “But I’m glad you’re home.”

“Ok.” Kyojuro’s eyes soften. “You did a good job though.” He shouldn’t have had to, but Senjuro’s been forced to grow quickly. “We’ll do something for you though. Whaddya want? We can get dessert or go to that fancy ramen place or whatever else.”

Senjuro sniffles again. “You’ll be mad at me.”

“Of course I won’t, you can choose anything.”

“Ok.”

—-

A demon was not was Kyojuro had in mind. He had lightly protested at first but after Senjuro relented with a horribly sad look the man ended up being the one to insist. He bit back the opposing words on his tongue and tried to be supportive.

It was obvious the boy had been thinking about this for quite some time. He already had a list of several local rescues and even pulled an older futon into one of the many spare rooms they had.

Rengoku had trouble keeping a solid smile on his face, but even when it slipped his brother didn’t notice.

So they (well mostly Senjuro, who finally insists on going one day after school) arrive at a vaguely creepy facility, white walls with rows of cages on either side. The cashier is a young woman who drags her voice out too much, weirdly high in an attempt to appear more friendly. Her lax appearance was strange with the rest of the sterile environment.

Senjuro was free to pick one of his own out. Kyojuro found all of them equally repulsive, and had no preference for which one ended up in their home. The only thing he wanted was for his brother to change his mind and let them leave empty handed. He felt bad for thinking such bitter thoughts considering what had propelled their visit. Everytime he tried to improve his attitude Rengoku would catch sight of meat sitting in feeding bowls or little signs declaring the temperament of a specific pet.

Senjuro was firm in his choices however and they ended up with something vaguely human, though that wasn’t very remarkable. It (They, Senjuro kept on insisting, like it was an actual being) had greyish skin and sunken eyes. With a few random spikes and other inhuman qualities it was pretty typical in terms of demons. It wasn’t the most repulsive one there, plenty had more appalling traits like multiple eyes or huge fists perfect for clawing people.

The chatty saleswoman cooed as she opened up the cage and beckoned you forward. “Good choice! This one’s quiet, but the most well-behaved cutie you’ve ever seen.” As you drag yourself out of the cage and rise to your full height Rengoku grimaces. You don’t look particularly threatening, smaller than him with blank eyes and greasy hair. ‘Cute’ is not the word that comes to mind.

Hesitantly taking the new leash clipped to your collar Senjuro tugs you forward. You move along with the motions, following quick enough that the lead never draws taut. One of your feet drags slightly each time you take a step.

“Hi.” The boy is so quiet as he whispers it. He seems a little shy, reverent maybe? Holding eye contact for only a moment or two he looks away and back towards his brother. “I want this one aniue.” The shyness holds as he

at Kyojuro.

The man bites his tongue for a minute and tries to think of an appropriate response. “And you’re sure?” He tries to keep the judgement out of his voice.

It’s detected anyways. Senjuro’s brow furrows slightly. His brother is never truly angry, but annoyed seems like a just reaction. “Yes! I promise.” The words rush out quickly in a way that leaves no room for argument.

“Awesome! And just so you know each adoption comes with some basic care items, a bit of meat, feeding bowls, um I think there’s a booklet included.” The saleswoman bounces around the counter and roots in the drawers underneath. “Is this your first one? Honestly I thought about adopting in the past but after spending all my time here I’ve gotten my fill of demons.”

Senjuro nods along politely to each sentence. Rengoku merely stares out the window and waits until she asks for a card. When she finally finishes her spiel he slaps the card down. Demons can be low-maintenance (in actuality that means negligent owners who can’t quite get in trouble with how resilient demons are) but when properly taken care of they can be rather expensive. The cost of meat alone, synthetic human or the animal kind, can scare many away. Money here isn’t the problem.

Kyojuro has to carry all the accessories back to the car. His brother opted to chose about a dozen different types of collars and bowls and whatever else in his excitement. Trailing behind slightly he still holds your leash in hand. Every few steps he’ll nervously look back as if to make sure you’re still following. You don’t react to any of these glances, don’t react to anything at all other than stopping when he does and moving forward when prompted.

Once you’re brought to the car Kyojuro directs you towards the back, where several plastic covers have been put over the seats. Senjuro has to lean over to buckle you, jolting each time his skin brushes against yours. Pulling away he hovers for a moment before his brother directs him towards the front seat.

—-

Their house is nice. You’re led to a mostly bare room which is dubbed as yours. The older Rengoku dumps the toys in the corner and is quick to leave afterwards. You can still smell him sharply though, lingering just beyond the doorway.

The younger one parades you around the room to show off the space. Currently there is a futon in the corner with a shelf pressed against the opposite wall. Senjuro promises to get you more to furnish the space but it makes no difference to you.

“I’ll see if there’s a salon or something like that. They can bathe you and help with your nails.”

They’re claws, pointed and sharp but also splintering from lack of care. With no other way to respond you give a dull nod.

“I didn’t really think about clothes, but I do have an oversized shirt for you. It’s more like a dress really.” While explaining he plucks the piece from the bottom of your new belongings. “Aniue might have some old clothes that fit you, just until I go shopping.”

At that your mouth drops into a sharper frown. His brother smells like anger and hatred and something too harsh for your nose. It’s not as if you’re not used to being disliked. Demons generally don’t get along with one another and being put in a shelter usually meant whatever previous owner you had wasn’t great. His distaste though was sharp on your tongue as the smell wafted through the air. It wasn’t like casual neglect or dehumanization— there wasn’t even subtle joy taken in the sight of your current state, he didn’t want you there at all.

Put off by the thought of the man you turn away and crawl underneath your futon. It’s warm against your chilled skin. Peeking your head out from the thick sheets you watch as he spreads the rest of the accessories around the space. The whole time he talks softly, not to you specifically, but fills the space with sound. He’s quiet and doesn’t say things pointlessly which keeps your annoyance from rising.

By the time he finishes you’re already half asleep. You’ve spent the last few months sitting in a cage most of the day, even just moving from one home to another has worn you out. Nerves alone keep your eyes open, at least while he’s in the room. The moment he leaves however your willpower thins.

—-

Days pass slowly. Senjuro feed’s you before he heads to school, at which point you’re mostly left alone. Kyojuro occasionally passes the room, but never pauses. A few times when it’s absolutely silent you’ll poke your head out of your room. You don’t ever end up passing the threshold of it though. Nobody’s invited you outside of the space and you don’t fancy getting punished for such a small journey.

Mostly you nap or pace around your room. There’s not much in terms of entertainment but it’s not a horrible existence. Senjuro is only gone for a few hours. When he gets home the boy will do homework in your room. It becomes so much of a habit that an extra desk gets shoved into the space. While he works you rest at his feet or watch him through your blankets.

Your routine rarely shifts, which is nice in its own way. Change is more often bad than good, but the humans seem to have their own ideas about what you need.

This afternoon when Senjuro enters his brother follows. When you sense Rengoku approaching however you try to scramble backwards. Senjuro’s arms stick out in front of him as he tries to calm you. You’re not very happy but you soften slightly anyways.

Now that you’re paying attention his words make real sense. “I want you and aniue to get along. He’s not mean so you can’t be either.” His brother stands in the doorway, looking threatening still.

“Please aniue, you have to be nice.” Senjuro looks up at the man. “Can’t you just pet them once? I don’t like it when you ignore each other.”

Rengoku approaches you carefully. In an attempt to please his brother the man wasn’t quite as brash as usual. But his feelings were still clear on his face, and the smell of his anger flows through the air. You’re tempted to back up even more, hiding flat beneath the chair.

In turn his expression only grows more displeased.

After a few minutes of him standing angrily in the middle of the room Senjuro observes the threatening aura easily and was quick to intervene. “Aniue! You have to be more gentle.” He runs to your side. Though the boy wasn’t particularly strong you allowed him to pull you into his lap. His soft hands run over your hair in soothing motions. “See, you have to be nice if you want them to trust you.” While he continued to cradle you an eye opened to peek at the elder brother. He looked even more upset than before, which brought a sly smile to your face.

With your sharp nose you could smell how hard Kyojuro had bit his tongue. The faintest smell of blood drifted in the air while saliva pooled in your mouth. Turning your smug face away you attempted to burrow further into the carpet and soft fabric. You roll around in the gentle feeling of his hands and the sweet smell of his clothes. He must’ve been cooking earlier, something sweet like sugar or baking mix is smeared over the front of his clothes.

Though you’ve hidden your face Kyojuro’s presence is still clear. When he settles beside you all your muscles pull tight. His hands graze over you twice while you lie as still as possible.

“Alright, is that good?” The man is already standing up.

Senjuro doesn’t seem satisfied at all, with your performance alongside his brother’s, but nods anyways. It seems the mood has gone sour, the way he leaves soon after. He tries not to make it feel like a punishment but a bit of guilt gnaws at your bones.

—-

The next day Senjuro is back to his usual routine although the air still feels a bit too quiet. Worry keeps you alert to his movements. A few times he opens his mouth without speaking. On the third or fourth try he finally manages to get a few words out.

“I’m having aniue take you to get all washed up and everything tomorrow. You have to be good otherwise he won’t want to do this for me again.” His sternness is in full force, and surprisingly authentic. Blinking up at him you give a curt nod, waiting for the petting to resume.

It does soon enough and you’re happy to settle back down.

—-

The spa- salon or whatever they call themselves is surprisingly pleasant. You’re shy at first. There’s lots of people there, other demons too. Some are carefully restrained, muzzles and harnesses and even one fashioned in a straight jacket.

You wish Senjuro had taken you. The boy would’ve coaxed you inside gently and explained everything along the way. Rengoku drags you towards the receptionist and clips your collar to one of the tethers there. As soon as you’re checked in and given a pickup time he leaves you there. You’re not shaking— that would be cowardly —but there’s a nerve running through your body.

The woman who takes you is nice. She has pretty pink hair with a friendly face, but ultimately is unfamiliar in a way that makes you resistant. When you don’t move with her she trues to guide you with a hand. It’s so warm again your skin. Senjuro’s touches are always light and the woman isn’t rough but it’s rougher than he is.

The hiss isn’t purposeful, not even threatening. It works to describe your discomfort. She tries soothing voices to guide you towards one of the chairs, but you stay rooted to the spot.

“Five steps ok? Why don’t you move with me and we can sit down.” When she nudges your legs you finally take one step. The woman guides you slowly until you settle down on one of the recliners. You’re still stiff, but in a position where they can start to take care of you.

Lots of different people do lots of different things. A man trims your talons and applies a thick shiny coat over them. He offers color but you staunchly shake your head.

Another person trims your hair. She carefully moves it away from your face and takes off a minimal amount. You can’t really see much of a difference, too distracted by all the little ends that have scattered across your face. The woman dusts them off with a fluffy brush that makes you sneeze. Everyone nearby coos after and you feel like more of a lapdog than a demon.

Someone else leads you over to a private bathroom, where you’re promptly scrubbed down. They use lots of bubbles and scented oils that edge on being too much for your senses. The after-effect is nice though, a calm lavender scent that’s much more pleasant than dirt and raw meat (even if the latter was tastier). You’re thrown into an oversized sweatshirt with matching pants, soft fleece lining the inside.

It all goes rather quickly. There’s dozens of new scents and people that cloud your brain. It’s hard to absorb the reality of everything until you’re allowed to actually rest. A side room lets you find a quiet place to curl up and rest.

Even though you’ve done just the barest amount of stumbling around there’s a weight to your bones that drags you down. You can’t remember if you were always like this or if it’s a side effect of being caged for so long. Either way you feel like a poor imitation of what a demon should be. A poodle compared to a wolf.

Part of you doesn’t really care. It’s not like you’ll ever be expected to kill or even hunt. This is the result from years of domestication.

You leave all the wondering for another day. Your mind is just a tired as your body and it’s no surprise when your eyes slip closed.

Kyojuro drags you back into the car after a harsh awakening. You’re still half asleep but stumble out once he has a hand on your leash.

Slumping over in the back seat you drift back in and out of sleep. Everytime the man hits the breaks you jerk forward and wake back up.

But by the time you get home you’ve been knocked out fully. Your head dips downwards only to lose ok up an indeterminate amount of time later.

For a few minutes you wait awkwardly in the car. It’s hard to tell how much time has passed, but in reality it probably hasn’t been too long. Senjuro would’ve come out to wake you if he was home.

You decide nobody else would be inclined to fetch you. Crawling out of the backseat you dart towards the door leading inside.

Unsure of where exactly your room is you’re forced to rely on scent. You’ve never been outside of your room in length, and can’t recall the layout of most of the home.

Currently your strategy is to point your head in one direction and sniff. It seems to be doing a relatively good job of leading you in the right direction, or at least the smell isn’t getting any weaker.

Though much of the house is rather boring, plain walls with nice furniture that doesn’t really tell you anything, you do take note of whatever is a little interesting. There’s fresh flowers in one of the vases along the hallway. They must’ve been cut just a day or two ago. As you pass the kitchen you notice four seats at the dinner table, with room for more if needed. You haven’t heard any guests in the weeks you’ve been here, so it’s an odd sight.

Kyojuro seems to be absent at the moment, making your movements much more relaxed. You don’t drag your feet or wander aimlessly but you’re happy to poke your head in certain places were it doesn’t belong.

One room in particular captures your attention. Most of the home smells the same, with the brother’s scents flowing and ebbing depending on the space. In a darker hallway however there’s the sharp scent of alcohol. Underneath it you can sense another human within, a damp smell like overripe fruit. At first it makes you pause (the only sound is heavy breathing inside the room) and then scurry away from it.

You find your room soon after, happy to dive into your sheets. Pulling off the oversized clothes you’re happier to take in more familiar fragrances.

—-

When Senjuro gets home he showers you with compliments. Fingers sweep through your soft locks.

However he seems determined at ruining your peace. “Wasn’t Aniue great for taking you?” He tries to hide his pointed tone.

You give a non-committal shrug.

The boy huffs but doesn’t leave you like he did last time.

“They were booked too far ahead on Saturdays but next time I’ll plan for that so we can go together.”

Letting out a pleased trill you flop onto the ground.

The boy moves backwards. “Let’s get some food yea?” He waits for you to follow.

Never having been invited out of your room (Kyojuro taking you out earlier was less of an invite and more of a demand) you move hesitantly. Within the home there’s no leash attached to your collar. It’s nice most of the time but you could use it as proper direction for where he wants you to go. Every few steps you end up stopping because you’re so hesitant. You’re just grateful that Senjuro doesn’t mind how slow you make the journey.

The open air of the kitchen makes you nervous. There’s so many places to look that it makes you dizzy.

Senjuro opens the refrigerator. At the bottom there’s stacks of meat, all different kinds. Technically it makes sense. It’s not as if someone is purchasing your food everyday. The steaks and patties you get eat night have to appear from somewhere.

With it all in front of you however saliva fills your mouth.

“You can pick out your dinner this time. I thought that could be fun!” He pulls your arm towards the icy cooler.

Moving slowly you just point to the top of the pile. You’d eat the whole thing if you could, but given the choice to pick one there’s not much difference to you.

Senjuro looks a bit disappointed so you instead take more action. Moving the packages around pointlessly you choose another from somewhere in the middle. The letters outlining it explain nothing to you, but there’s juice and blood flowing around the free spaces. Mostly you’re just excited to run back to your room and sink your teeth into the fat and sinew. It leaves saliva pooling in your mouth.

With slightly shaky hands you hand it over to Senjuro. Even though you know it’ll end up back in your hold your instincts scream at you to keep it. The tips of your fingernails burn as you try to keep your claws in control.

With dilated eyes focused on the meat you don’t notice the smell of alcohol wafting into the room. The younger boy does, and he tries to take your hand and guide you away. As you’re unworried you drag your feet along the way. Ignoring his urgings you’re caught off guard when a hand hooks into the back of your shirt.

Turning around you think it’s Kyojuro who’s grabbed you. They look almost identical but a bit of extra height and some light stubble indicate him as someone else. You may be dumb but you’re not stupid and it’s easy to guess that this is the pairs father. You hadn’t considered the full image of their family, only caring to note those you interacted with.

His anger is different than Kyojuro’s. Is less pointed, engulfing the whole room rather than poking your skin alone. It smells rotten.

“Who brought this damned thing into my house?” Shinjuro’s question doesn’t require an answer, it’s already obvious. You try to turn tail and race into your room once he releases you, but you’ve been turned around and there’s no clear line to the exit. Senjuro reaches out to his father, trying to calm him.

“Aniue said it was ok so I just thought-“

“Kyojuro’s not your father is he?”

“N-no but-“

“Stop letting him act like he runs the fucking household. If he wants to be in charge he can get his own place.” Along with his cruel words his hands twist into fists. As an arm raises Senjuro shakes in anticipation.

You dart forward, nearly knocking the boy over. A strong fist collides with your forehead. You’ve been hit before, but you can’t remember a time a human had been able to hurt you this much.

Knocked off balance you’re happy enough to crouch to the ground. As the room comes back into focus another hand comes towards you. Lifted up harshly you’re face to face with the man. You’re hissing and spitting as you resist Shinjuro’s grip. Lying down and drinking had brought down the man’s physique, but shadows of muscle still remained. He clutches your hair in one hand. The minute you raise your claws he captures your wrists in the other. You try to gnash your teeth and aim yourself at his skin, but you can’t get near him. The best you could do now was lash out with your legs.

Twisting like a serpent you tried to loosen his grip. Senjuro was crying as he pulled on your clothing, trying his best to free you in his own way.

You’re only dropped when a door at the front of the house softly opens and shuts. The noise is barely perceptible to human ears, but Shinjuro still senses it. The moment he pushes you to the ground the man is quick to disappear back into his room.

Senjuro dashes to your side. At the moment you curl into yourself. The bruises around your wrists are already fading but your muscles are stiff when you move.

The boy clutches onto your body like you might be dying. Currently you’re not inclined to brush away his tears though you wish they’d stop.

“What happened here?” For once Kyojuro’s voice isn’t obnoxiously chipper or filled with disgust. There’s a genuine tone that you’ve never heard before. You still don’t bother to glance his way, trying to find comfort on the hard ground.

“F-father he um, he was being mean again and when he tried to grab me they got into a fight.” His voice is still thick with emotion as he crouches over you.

“Oh.” Kyojuro’s surprised. It’s silent for a quick second. “Well are you ok?”

“Aniue! I’m fine. Don’t worry about me.” His arms grab your torso and try to lift you. With shaky arms you attempt to help him. There’s no reason you should be in such a weak state, perhaps after being pampered for a bit you’ve lost touch with what it’s like to be beast.

When the eldest is quick to scoop you up you’re at least well enough to let a quiet growl leap out from the back of your throat. You don’t move however. It’d be awful to get dumped on floor again and Kyojuro’s body is very warm against your side.

That doesn’t change the fact that the minute he sets you down into your room you run for your sheets. Hiding beneath them you try to peek without being caught. The worry is worthless because Rengoku has already disappeared and Senjuro is in his place.

He hand feeds you chunks of fancy meat, you think it’s cow, and pets your hair while you try not to fall asleep. The boy is whispering all kinds of praises that melt into one another but the culmination of all of them buzzes under your skin. Senjuro is often quick to praise but you’ve never felt as if it’s been truly earned.

—-

The next day Kyojuro approaches your room (willingly) again. Senjuro is already is his typical spot while you hide in the corner.

You’re surprised, but not enough to move. Glancing up with tired eyes you watch him go towards his brother.

“How come you took them out of the room?”

“I- Aniue! I said I was sorry.”

“I know, I’m not mad or anything ok? You just gotta tell me what’s going on.”

You stick your head out of your bed to listen. Kyojuro gives you a curious glance before looking away.

“Um, Muichiro-kun said it’s good to involve demons with their feedings. It cultivates bonding. He said he saw it in an article online.”

The elder brother sighs deeply. “It shouldn’t have to be this way but I need you to ask me before you do things like this ok? I’m just looking out for you.”

“I’m sorry aniue.”

“Don’t be. I don’t- you shouldn’t have to be sorry. I’ll have a talk with father.”

“It won’t do anything,” he mumbles under his breath. Perhaps Senjuro is feeling especially bitter today.

Kyojuro frowns but can’t muster a response. His eyes sweep over the room before the man turns around to leave.

—-

It’s another day where Senjuro is gone but the eldest is still home. You can’t keep track of the days or form any sort of schedule, you just know this happens on occasion.

You creep out of your room early in the morning. Though you can rely on scent to lead you it’s not as good as simply knowing the space. Every few turns you convince yourself you’re passing something relatively familiar.

After minutes of wandering you pass the room that contains Rengoku. The door is open so you step inside, then back out, and then back in. You’re not sure how to grab his attention.

Turning around you leave, only to re-enter. This time you let your foot collide with the door. The small tapping noise grabs his attention. You try to resist the instinct to hide. For now you just slouch more and hold your arms to your chest.

“What do you want?” Kyojuro speaks normally for once. You could imagine him asking anyone the question.

Peeling back your lips you try to get your vocal chords to form the proper noises. Instead of words you push out a low grumble that leads into a whine. You try the action several times to imitate something he could understand.

Moving closer you attempt the noise once more. His face holds a confusing mix of emotions, still a bit of disgust hidden within the layers.

Bowing your head and rolling your shoulders you hope that body language could bridge the gap in his understanding.

“Are you saying sorry?” At the question you look up and nod eagerly. Your face can’t form a proper friendly smile, but the result is hopefully close enough. It’s silly but a sense of accomplishment washes over you.

The man smiles back (his is warm and honest, painted with a touch of surprise). “Oh, well, thank you I suppose.”

A beat of silence. You wouldn’t be able to respond with anything other than more primal calls.

“And you do a good job of taking care of Senjuro. I’m glad someone is here for him when I’m gone.”

Ignoring the underlying bitterness (jealousy? blame?) you nod once more. As your head bows a sneaky hand rises to pet it. Kyojuro only taps your hair once or twice beneath turning and returning to his work.

Pleased you make sure there’s nothing remaining before running back to your room.

hantengu clones pet au headcanons

DEAD DOVE DO NOT EAT. read at your own risk. this is bad.

background

> in the present, humans are no longer the prey of demons. the further development of high-concentration of wisteria poisons, as well as the integration of tranquilliser bullets, has gained humans the upper hand.

> wisteria weakens the demons, disallowing their use of their blood demon art, if the poison is concentrated enough.

> muzan has gone dormant, and the demons he’s made are left to their own devices.

> most demons often surrender themselves to be captured, and sometimes domesticated.

clones

> the main body was hunted down, and then cut, so the clones formed. However, they were overwhelmed before they could form Zohakuten.

> they no longer look *exactly* the same, since they’ve been treated differently.

> They had been separated upon capture, then shipped to all sorts of places. Here’s what happened to them.

tw.

once again, DEAD DOVE DO NOT EAT. read at your own risk. this is real bad.

graphic depictions of violence, torture, starvation, nsfw, mental and physical abuse, experimentation, absolutely inhumane acts, no comfort whatsoever

sekido • graphic depictions of violence.

> for his aggressiveness, Sekido was brought to an underground fighting ring, where rich people place bets on their favourite demons.

> he’s lost many rounds, resulting in beatings and whips, from angered betters who lost money from trusting his agression. They would pay the guards to starve him as punishment, and he would hunger for weeks on end.

> sometimes, before a fight, the betters will starve him again, but not for too long. This is so that he would become more aggressive for food, and that he’ll try to eat his opponent.

> Sekido’s body still has muscle, albeit little fat. his skin is covered in countless scars; bite marks, burns, whipping, stabs, etc. All of them are half-healed, his malnutrition disallowing his recovery.

> he no longer has his kimono, since all “clothing” are taken away from the demons. It is imposed that they deserve no covering, since their only purpose is to fight.

> because of his aggression, he is forced to wear a muzzle off-arena. It’s tight and bites into his skin, causing a terrible rash around his cheeks and neck.

> Sekido’s left leg is broken, the knee shattered and the ankle twisted at an grotesque angle. Since he’s not one of the top fighters, he is given no medical attention, and is left to feel a constant ache.

> he rarely fights anymore, and is left in his cell to remain in agony.

> but he’s more of a ‘safety net’ for betters, since he cannot die. The main body remains unharmed, so Sekido has no choice but to endure and live through all that happens to him.

~ Sekido greatly regrets speaking harshly to his counterparts, because in the end, he cared about them. He missed them all; Karaku, Aizetsu, Urogi. he just wants to see them again.

~ he hates himself for being so weak, wishing he found a way to heal faster. But it is never possible with an empty stomach.

~ Sekido hates sleeping, since it’s a form of weakness and vulnerability. But he’s become so weak and starved that he has no choice, and when he does sleep, all he sees are his brothers.

~ He often sleep talks their names, and is prodded and sometimes beaten by guards to make him stay silent.

karaku • nsfw.

> Karaku was originally brought to another underground fighting ring, but one of the betters found him cute, and bought him.

> but since then, he’s been majorly neglected by that better, who was an impulsive buyer and only played with him for a day.

> he was resold to one of the buyer’s friends, who placed him in an exotic sex house. People go there to fuck with animals and stuff. demons were of the same level of animals, so Karaku was a ‘perfect fit’.

> he’s often tied down in compromising positions, allowing for patrons to use him however they want. Sometimes they inject him with aphrodisiacs, so his body would react better to their actions.

> they feed him considerably well, making sure that he stays good-looking. The food is often raw pork mixed with blood. Karaku eats it all up because he’a often tired after long, excruciating hours of twisted people using his body for fun.

> he often has a muzzle, since his sharp teeth are a hazard to patrons. The muzzle can be swapped out for all sorts of gags and whatnot. His nails are clipped and often he wears gloves to prevent patrons from getting scratched by him. He has a shock collar that activates either when he disobeys an order, or when a patron uses it to fulfil their twisted desires.

> he feels a constant, dull pain in his abdomen, because unbeknownst to the house owners, his insides had gotten ruptured by one overly-excited patron. Karaku needs human flesh to heal better, but since he’s just given pork, the healing process isn’t going well.

> whenever he’s used, he would whimper and hiss because of the pain, but patrons just assume it’s because of the stimulation, and continue ramming directly into the spot that hurts him so much.

~ he constantly wishes for everything to end, for someone to find the main body and just kill it.

~ he hates that he feels this way, since he knows he’s supposed to be the manifestation of pleasure, and that he should be feeling good, right?

~ Karaku has given up almost completely, often laying motionless when left alone, showing no signs of trying to escape.

~ his body is maintained by the owners and not him, and they punish him (shock collar) whenever he doesn’t eat.

~ Karaku often thinks about how life was before all of this agony, and wonders where his counterparts are now. He wants so badly to get back to them, and for all of this to end.

~ at night, he would sometimes cry because he misses them so much. But he keeps his cries quiet because he doesn’t want to be punished for making noise.

aizetsu • experimentation.

> unlike the rest, Aizetsu wasn’t sold anywhere (underground fighting, sex shop, etc). the original captors kept him, but sold the rest to fund their activities.

> his captors are in a scientific organisation, and he is one of their test subjects. His register number is 412G and he is kept in their more reinforced rooms.

> they have the main hantengu body, and understand that as long as it is unharmed, Aizetsu should regenerate.

> they experiment on him often, since his special case allows him not to die.

> they develop concentrated wisteria poison and inject it into him to witness the effects, and how long it takes in theory for a demon to fight it.

> whenever this happens, aizetsu cries and tries to huddle in the corner of the lab, because all the wisteria does is burn.

> his insides light on fire and his intestines feel as if they’re rupturing all at once. He screams, twisting and contorting himself, trying to find salvation from the pain but to no avail.

> the burning can last for days on end, as they inject higher and higher concentrations of wisteria. Aizetsu wails and shivers as the scientists show no mercy when handling him, using machinery to hold him in place when necessary.

> they don’t use anaesthesia because they ‘need to see the true effects’.

> Aizetsu is only fed water, and other nutrients are injected into him every morning, afternoon and evening. He also has a exercise routine, but he barely follows instructions, and remains shivering in the corner.

> aizetsu is extremely shifty, sobbing whenever someone tries to get close.

> sometimes, they use Aizetsu for psychological experimentation-

> leaving him starved for days on end, then seeing if he would eat, even if it means getting electrocuted when approaching the food.

> depriving him of breathing for several minutes, until he was barely conscious, and then ringing a bell. They will then see if ringing the bell independently will cause him to go dizzy.

> etc.

> Aizetsu often bites his nails from anxiety, so much that his fingers sometimes bleed.

> scientists ensure there are no sharp objects nearby, otherwise Aizetsu would try to cut himself.

~ Aizetsu never stops crying.

~ he horribly misses his counterparts, no matter ‘how annoying’ they were in the past. Day by day, he wishes he never scrutinised them when they were around. They were the only family he knew, and now they’re gone.

~ he has a horrible feeling that they’re experiencing things like he is, and maybe even worse. He often throws up at the thought, and is reprimanded by the scientists.

urogi • broken.

> urogi had been sold to a collector of sorts.

> the collector in question actually only wanted his wings and talons, so after purchase, requested for Urogi to be declawed and his wings amputated.

> in the waiting for the declawing/dewinging appointment, urogi thought that his owner cared about him, and was content with the care he didn’t know was only temporary.

> Urogi would fluff up in excitement whenever he saw food or the owner themselves.

> when the day came, urogi was obedient and friendly, thinking that he would be fine.

> but terror hit him when they strapped him down to the operating table, and took out the knives and tools they were going to use on him.

> it was an excruciating five hours-

> his wings were slowly removed, and he screamed and cried and tried to tell them to stop, but they put a shock collar on him to shut him up. The operators were unaffected since they wore rubber gloves.

> he had no choice but to silently endure the pain, soft whines of agony escaping him time to time. The blade dug into his precious, beloved wings, and soon enough, he found tears streaming down his face.

> and then his position changed. Since the owner did not care for him and only his wings and claws, the operators could do anything with the rest. They placed him on his back, sending sharp, violent pains throughout his body, the open wounds of his wing-bases pressed on the table.

> and his arms were strapped above his head, and bright lights shown on his face.

> he screamed again, causing another shock through his neck, and to follow that up, he felt a sharp piercing red feeling at his knuckles.

> his talons were pried off his fingers, from their very bases, at his knuckles. They tore of the surrounding skin bit by bit, forcing whine after whimper out of him, ignoring all forms of pleading.

> his remaining body, robbed of all of his prized features, was left in the warehouse of the collector.

> chained up to a pole, he softly squeaks at any shadow that moves, hoping and praying for rescue.

> stuck starving to death, but since the main body was unharmed, but he would never die.

~ urogi simply waits until his counterparts would come get him.

~ whenever they fought, they had his back, didn’t they? Wouldn’t they help him now?

~ why weren’t they coming? Did they forget him?

~ and the horrible realisation, that they were maybe captured too, dawned upon him, and his heart screamed in terror and denial.
