Your arrival came as a surprise to the Demon Slayer Corps' hashiras. When Kagaya introduced you as the new Star Pillar, your head spun. Nervous, tense, and curious about who your new fellow Pillars would be.
Of course you were welcomed, or at least by most people. Especially by a certain blond guy with red highlights who never stopped smiling at you for a second as he stared at you during your introduction.
Luckily for you, it was that kind man in the fire haori who was assigned to guide you through the things you needed to know now that you were a hashira: locations, schedules, training, and apprenticeships. So, after introducing himself as the pillar of flame, Kyojuro Rengoku, he was guiding you to your new home.
“And right here is your estate, it’s close to mine, that’s really good luck!” Kyojuro says enthusiastically, leading her down a path toward a beautiful garden, and a few meters away, a beautiful, rather large estate. You smile as you look at the beautiful wisteria trees, then turn to look at the outgoing man.
“That's great, do you live here too?” you ask curiously, as there are some properties provided by the hunting corps, but there are also other people who already have their own homes and don't use them.
“I have my own estate, which, as I told you, is just a few meters from here, but I'm not going to lie to you, I spend more time going to my house to see my little brother.” Kyojuro smiles at you kindly, as he guides you towards your new home, up the small stairs that led to the main door.
You look at him with bright eyes, nodding at the handsome man's response. You thought for a second about what you were going to say. "Well, you're welcome to come here anytime," you say with a slight smile, walking past him, seeing how his smiling face turned slightly surprised. "To chat and have tea, of course," you clarify softly, laughing slightly when you see him almost trip on the stairs behind him, leaving with a smile, promising to see you again and inviting you to train with him whenever you like.

“Hello?” You say in a curious whisper, approaching one of the farms where Kagaya told you to go to train with another hashira. A few meters away, you saw a man with white hair and lavender eyes covered in scars. His shirt was open, revealing his muscular chest. You’d be lying if you said your mouth didn’t water at the sight. “Kagaya told me to train with you. You’re Nemi, right?”
The man stops his training with his wooden sword, looking at you with irritation. “I’m SANEMI, not Nemi, fuck,” says the white-haired man, sighing heavily while running his hand over his face in irritation. “And yes, I was already informed. Come on, I don’t have all day.” He carelessly throws a wooden sword at you, starting to walk towards the center of the garden, without turning to look at you.
You frown as you follow him, not wanting to say anything so as not to make the situation worse.
But the truth is, it was torture. Even though it was just training, Sanemi showed almost no mercy towards you. He proved to be very strong and was almost impossible to touch.
“Nemi, please, could we take a break?” You say in an exhausted tone, breathing heavily, sitting on the floor as you catch your breath, a few beads of sweat running down your forehead and body. Sanemi was a little sweaty too, but it almost seemed like he didn't intend to stop.
“I already told you not to call me that, damn it” A light blush spreads across the white-haired boy’s cheeks as he looks at you, his eyes lingering longer than necessary as he watched you take off your uniform jacket, revealing your sweaty torso and a slightly pronounced cleavage due to your white tank top, plus the panting didn’t help your image much either “Having a pretty face doesn’t get you any benefits here”
You're slightly surprised, then laugh, "Do you think I'm pretty?" You say in a mocking tone, at the same time Sanemi's cheeks turned even redder, earning you a soft smack on your head due to your cheeky comment.
Of course he wasn't going to admit it, but from the first time he saw you, he thought you were very pretty.
_____________________
As the months passed, you became very close to Kyojuro and Sanemi; they were like oil and water to you, and it was also fun to spend time with such different people.
Being with Kyojuro meant arduous training, but he always made sure not to overexert yourself or hurt yourself, then went out to eat at different restaurants in nearby towns where they would go on missions. And of course, he never missed the opportunity to hug you affectionately, praise you, and even tenderly kiss your hands. He was more outgoing; he wasn't afraid to tell you how beautiful he thought you were.
Sanemi, on the other hand, was more serious about it; his training sessions were rougher (not because he wanted to hurt you, but maybe he liked seeing you begging between gasps for him to let you rest), his missions often ended with you arguing, but then you made up, after so much silence on the way Sanemi always apologized to you in an embarrassed way. On a path away from prying eyes, before reaching the main residence, maybe he would try his best to brush his fingers with yours while you walked side by side, and maybe, you didn't mind leaving a kiss on his cheek to see how red it turned, or how he held back when he saw his eyes darken.
For both of them, it was torture to see you spend time with each other. The way you looked at them from below with your long eyelashes, the way you got closer to them, or the simple fact of knowing that you had to go with one of them on a mission that could last for days, generated a wave of jealousy that was increasingly difficult to hide.

It was afternoon, the sunset casting warm reflections across your garden as Sanemi approached your estate. His head was spinning, but his steps were determined as he walked along the stone path and up the small wooden stairs. Sighing softly, he knocked on the door with surprising gentleness, stepping back to wait for you to open it.
But he was greatly surprised to see that the person opening the door was none other than Kyojuro; he seemed to be wearing a smile, which quickly disappeared when he saw Sanemi.
“Kyo, who is it?” You approach from behind Kyojuro, peeking out to see Sanemi’s shadowed face. “Oh Nemi, do you need something?” You stand in front of Kyojuro, turning your back on him, and standing face to face with Sanemi, you were curious, you didn’t understand what the white-haired man was doing there.
Sanemi takes a quick breath. “Can we talk? It’s important,” he says abruptly, then looks behind you at Kyojuro. “Alone.”
“Oh, it's just that Kyo also came a few minutes ago for the same reason. I went to make tea, that's why I asked him to open the door... But we haven't had time to talk yet,” you say softly, turning to look at Kyojuro with a smile, and then looking back at Sanemi, who was already getting irritated at knowing about his partner's visit.
Oh, of course I knew it, it was the same as yours. I wasn't going to let him tell you before then.
“I like you,” Sanemi finally says, without nerves or irritation, wanting to look as calm as possible. “I wanted to tell you alone, but something tells me that it wouldn’t be possible.” The white-haired man looks with narrowed eyes at Kyojuro, who was standing with his arms crossed over his chest, looking at him with a certain anger, something that is not normal for him.
Before you can say anything, Kyojuro grabs you by the shoulders, turning you around to face him, his determined eyes scanning your face before he speaks. “I like you! Please be my girlfriend!” the flame hashira says resolutely, his determination igniting a spark in you that draws you in like a moth to a flame.
“Oh guys, I...” You were nervous, you didn’t know what to say, having two hashiras, one behind you and one in front of you wasn’t a small thing, and even less so if they were confessing to you. But what made you more nervous was seeing how they both looked at each other angrily. Sanemi took a step, pressing himself slightly against you, tilting his head to the side, looking at Kyojuro with superiority.
“Damn it, you couldn't shut your fucking mouth, could you? Did you have to do it today of all days?” the white-haired man spits angrily. His blood was boiling with nerves and anger.
Kyojuro frowns, undeterred by her insults, also moving closer to your back. “I’m sorry, Sanemi, but I came first, if you’ll excuse me.” Kyojuro’s calloused hands went to your waist, ready to gently push you back into the house.
Oh no, Sanemi wasn't going to allow it. "Fuck" he growls, and surprisingly, he grabs your chin, bending down to plant a hard kiss on your lips. The surprise was great, feeling his lips kiss you wetly, pulling your face towards him to deepen the kiss.
“Shit” Kyojuro curses, and without hesitation, he tugs at your waist, pulling you away from him. But without giving you time to breathe, he kisses you passionately. His lips move sensually, his tongue delving in to play with yours as his hands move down to lightly squeeze the flesh of your hips, panting your name into the kiss.
You were a mess, your legs shaking as your hands clutched his muscular arms, your face flushed. It was impossible for Sanemi to keep his cock from twitching in his pants at the sound of your soft moans. So he gently pulled your face away from Kyojuro's. A thin thread of saliva connected you, but he didn't care, kissing you wetly and eagerly.
Kyojuro doesn't say a word, walking back when Sanemi pushes your body inside your estate, it was a silent understanding for both of them: you wanted both of them... And who were they to not give you what your craving body was crying out for? The anger was forgotten the moment he saw your beautiful legs tremble with pleasure at the touch of both pairs of hands.
The three of them's feet were slightly clumsy as they climbed the stairs amidst kisses and moans until they reached their bedroom. Sanemi wasn't at all gentle when he kicked it open, revealing Kyojuro, who was fondling your sides with pleasure, walking backward as he opened your windbreaker and lifted your blouse, revealing your lovely tits.
His mouth wastes no time capturing a nipple between his lips as he falls back onto the bed with you on top of him. “What beautiful tits.” His hands play with your tits while massaging and squeezing them like a desperate man, looking into your eyes while he takes care to leave purple marks around them.
Meanwhile, Sanemi approaches from behind, removing his haori and jacket to stand behind you. His hands shamelessly lift your skirt, revealing your cute lace panties. “Look at her, the bitch was already prepared,” he says in a husky voice. Kyojuro narrows his eyes at his degrading treatment, but oh, seeing your body shudder at the dirty nickname said it all.
Sanemi slaps your ass hard and then pushes your soaked panties aside. Your dripping red pussy is on full display. Wasting no time, he kneels, spreading your folds to begin eating your pussy from behind. Kyojuro directs his hands to your thighs, holding them open for the wind hashira's mouth.
Sanemi was feasting on your pussy, pulling away to spit lightly on your clit, sucking on you, and shoving his tongue into your needy hole. “Please, Nemi.” Your moans are desperate, as you feel two of his fingers begin to fuck your hole, preparing you for what was coming.
After a few minutes, Kyojuro grabs you by the hips, separating you from Sanemi and lifting you slightly so he can pull down his pants, leaving his cock exposed, it was red and had precum dripping from it. “I’m going to fuck you so good, my love,” he says with a low moan, his hand directing his cock to your pussy, his tip rubbing lightly against your folds before heading to your entrance, positioning himself to begin thrusting his hips.
“Oh fuck, yes, Kyo.” Your moans are high-pitched as you lower your hips, reaching the base of his cock at the same time your eyes roll back. Soon, his thrusts start soft but strong, hitting that spot that had you seeing stars.
“So tight.” His words are low as he fucks you harder and harder, his hands squeezing the flesh of your hips, guiding you onto his cock. Kyojuro watched as your tits bounced in front of him and your head fell back.
Sanemi, on the other hand, pulled down his pants, sticking himself against your back as he puts two fingers inside your mouth. “Suck them good,” he whispers, and you obviously obeyed, running your tongue wetly and sensually over his fingers.
He roughly pushes them away, gently patting your cheek before directing them to your back entrance. “Open it, Kyojuro.”
The man with fiery hair looks at you for a few seconds, then nods. Without stopping fucking you, his hands go to your buttocks, spreading them open, revealing your rear entrance. Sanemi licks his lips, directing his saliva-soaked fingers there. “Take a deep breath,” he whispers in your ear before starting to insert a finger. The discomfort was strong but bearable, especially with Kyojuro impaling your pussy.
He soon adds a second finger, scissoring for a few minutes before pulling away. Sanemi spits on his own cock, stroking himself a few times before moving his head to your ass. “You’re going to take me so good, aren’t you?” His words in your ear make you moan, nodding stupidly. Kyojuro slows his thrusts so Sanemi can adjust.
Slowly, he begins to enter you, and you have to hold your breath as you feel yourself getting fuller and tighter. “God, they fill me up so good, so good,” you mumble, seeking Kyojuro’s lips as they both begin to thrust into you.
Their thrusts are synchronized; Kyojuro's gentle yet strong thrusts complement Sanemi's quick ones. All you can do is moan against Kyojuro's mouth, sucking on his tongue as you roll your eyes.
Sanemi at one point grabs your neck from behind with his hand, pulling you back, making your back collide with his chest, his lips go straight to your ear “You love this, don’t you? Having two pillars at your disposal? Having our cocks destroy your beautiful pussy and your tight ass?”
“Yes, I love being used, it feels so good,” you moan, feeling your pussy getting wetter and wetter. Your fluids soak Kyojuro’s cock, dripping down his abdomen.
Kyojuro moans huskily, his hand moving down between your thighs. “Give this needy clit some love, okay?” His fingers rub gently, causing a wave of moans from you, feeling your belly clench more and more. “That’s it, good girl”
Your hips spasm, as you feel that delicious pressure in your lower belly. “I'm... cumming,” you moan, and before you can think about it, your pussy contracts violently, your entrances squeezing both cocks tightly at the same time that your pussy releases juices that soak both of their cocks.
The two hashiras didn't have any more time, a few more thrusts and they both cum inside you, making sure that your interior is impregnated with their seed.
The three of them breathed heavily, lying down on the bed tiredly. They felt as if they had battled a thousand demons; the sexual energy and desire they had pent up had been released.
The moonlight adorns the room, where you were lying between the bodies of both pillars, who, leaving their complaints aside, decided not to say anything and simply snuggle up next to you.

Obanai and Uzui watched in disbelief as their best friends talked quietly on the garden bench of the demon hunters' central residence while eating their bentos.
It was no secret that Sanemi and Kyojuro had been getting along like cats and dogs over the past few months, trying to win your love; but it was impressive how calm they were now, chatting as if nothing had happened between them.
“Well, the important thing is that they get along better,” Obanai says with a raised eyebrow, crossing his arms. “I don’t know what that girl did, but I’m sure everything ended well.” Uzui nods slightly, his narrowed eyes scanning them before sighing, shrugging his shoulders.
“I don’t know, but whatever helped them must be really great.” The sound pillar looks at Obanai with a smile, who nods in agreement.
“Yes, I hope they continue like this.”
