Work Text:
The reader is sixteen.
Ever since you had been introduced to the nine Hashira you had been feeling... Different.
Especially around Rengoku.
Your life was no longer plain, boring, the world was colorful and bright and you allowed yourself to easily get lost in it.
Despite knowing who he was, you were attracted to him, you were everything he wasn't, pessimistic, cold, Rengoku was optimistic, joyful, loving.
And you hated yourself for loving him.
"Stupid, Stupid!"
You whisper to yourself, clenching your fists as you weakly batted your arms at the punching bag that stood before you.
'how could I be so stupid as to fall in love with the FLAME. HASHIRA.'
You growled, clenching your jaw as you continued your assault on the bag.
'but he's so kind; and loving; and caring; and he's perfect; and he would never be in love with me.'
You grit your teeth
'I'm such a fool, thinking such a powerful man going on twenty-one would be in love with someone who's barely sixteen!'
Your back arched as a strong pain thrummed throughout your body.
'ouch, and, strained back'
You thought to yourself, holding your back and sighing, sweat trickling down your brow as you panted.
You stopped in your tracks when a booming voice called out from the hallway.
'that voice...'
Before you could do anything, the door slid open to reveal Rengoku, and you were sure your heart had skipped a beat then and there.
He always looked so handsome in the mornings, his smile was softer than usual and he was generally calmer than, say, mid-day.
Hooded eyes met yours, a beautiful gold glint bled into red.
Your heart beat in irregular rythmes as you struggled to maintain eye contact with the handsome Hashira standing infront of you.
"My little flame, is everything quite alright?"
'oh God, that nickname.'
You froze up, your face burnt a soft shade of pink as he continued on.
"Little flame? Are you alright? You seem to be turning rather red? Are you hot?"
You swallowed thickly.
"Perhaps you should rest, you did seem to be punching that bag rather furiously."
He stares at the dented bag and nods his head in approval a short while after admiring your work.
"What strong hands, I'm glad to have you as my future successor."
You swallowed down your lust and spoke up, albeit, rather hastily, the words just kind of tripped and died on the tip of your tongue.
"Th-Than-Thank you L-Lord Rengo-ku"
You sputtered out.
"Please darling, just call me Rengoku"
He smiled, causing your heart to flutter
"However, I have noticed you have been acting rather strangely as of late, has something been ok your mind, little flame?"
He cupped your cheeks in his hands, the were warm, tender against your skin.
The action made you unintentionally bite your lip in anticipation, all of those dirty thoughts running through your head that you had forced out the door now came running back in with vengeance.
He noticed this action and quickly retorted
"oh dear! You must stop doing that, you could harm those pretty lips of your's."
Your eyes widened.
He called your lips pretty...
This couldn't be happening, this had to be some really, really realistic, perverse fever dream you were having.
"I..."
Your face burnt up a hot pink as his thumb gently brushed over your lower lip, your heart jumping out of your chest and racing as he brought his face closer to your's, the tip of his nosed barely inches away from yours, he was so close.
"Let me see" he whispered.
You audibly gasped and lurched backwards, causing him to pull away immediately.
"Oh dear, my apologies, did I crowd you? Was I too close?"
"N-No, it's fine!!"
You spat.
"You're getting hotter by the second, is there anything I can do...? No! There must be something I can do, there always is!"
He sounded so confident, it made something inside of you pulse, and something in-between your legs throb with want.
The Hashira could sense something was off, he breathed in, your scent was that of lust and want, though he couldn't be certain, smelling auras wasn't his strong suit.
And so, to try to coax something out of you, anything, he stepped forward and gripped your hips gently.
"If there is anything you wish to tell me,"
He paused, his lips closing in on your's,
"I'd be glad to listens and assist you."
You couldn't take it anymore, you wanted him, no, you needed him.
Your lips caught his in a passionate kiss, filled with want, he tried to pull away, but something in him wanted this ,desired this, he couldn't stop.
Your fingers entangled in his hair as he gripped your hips just a little tighter, causing you to buck them slightly, as you separated, both hot and gasping for air.
"I-I see"
He swallowed, breathing heavily, before regaining his composure.
"Though, my apologies, this moment shall be short lived, I am a Hashira, I am in my twenties, I am meant to protect you, defensless civilians, let alone my own apprentice, I cannot and will not harm you, no matter what."
You didn't know whether to be tuened on or feel belittled by the fact he called you defenseless despite being his own student.
He flashed you a bright smile,
"This was pleasant" he hummed as he went to turn away, but you gripped his arm and pressed your chest flush against his back; holding him close to your body, enjoying the warmth of his Cape.
You had no idea, or even control of what you were doing, it's like your body had a mind of it's own, and your body desired the flame Hashira more than anything at that moment.
Your breathing was laboured and uneven, he could feel your cute little heart trying it's best to keep up and steady it's beating against his back, and he couldn't help but to face you again.
"Is there anything I can help with?"
He whispered.
"I want you— no, I NEED you."
You were so confident in your statement, so bold, it was clear you weren't in control of your thoughts anymore.
"It's okay to be a teenager, Y/N, I understand that, but chasing after adults? It's not right."
He hummed against your neck, kissing it teasingly as to not leave you completely unsatisfied, maybe you'd go pleasure yourself?
"Rengoku--"
You moaned his name, voice low and filled with want as you rutted your hips against his.
"Please, Please, Please" you whimpered out, all that kiss had done was send a spark of hope through you, you were certain he had confirmed his affection for you.
Seeing you Infront of him, rutting your hips like some bitch in heat, it had him feel something, what was that something? He didn't know.
Something that set his heart ablaze, that made want pool in his stomach, something that made him painfully hard.
You sobbed gently as you gripped his arms, you really couldn't take it anymore.
He swallowed thickly.
'heavens forgive me'
He thought as he traced his fingers along your sides.
"Maybe I shall indulge you just a little longer?"
You nodded,
"Please" you sobbed out in a gentle, needy tone, as he nodded.
"Sit down," he purred against your ear.
You eagerly followed his every order, sitting down and managing to rest your ever-arching back.
"relax, and let me do all the work."
He raised your kimono, his touch was hot and loving against your cold skin, sending shivers up your spine.
He took his time with you, he did have all day.
He was infatuated with you and your body, running his hands along each and every curve, bump, and blemish on your body, the things you thought were imperfections were all being praised by the Hashira now.
It felt like years had passed until he had finally got your kimono off, reaching his hands down to the neck of the kimono and pulling the fabric to loosen it and tug it off of you, and you were certain he went feral as soon as he saw your barely clothed body.
Your lacy bra barely covered your breasts, yet it fit so perfectly around them, your panties were in just about the same situation as your bra, they clung to your skin as if not wanting to be removed, they were so pretty on your naked boy and complimented your complexion wonderfully.
Except one distinct feature about your panties, there was a large wet patch, causing him to smile sheepishly.
"Do I really make you this excited, little flame?" He whispered.
"My mouth may be able to spout filthy lies, but I assure you my body cannot lie" you responded, causing him to press his index finger against the wet patch, which in turn caused you to arch your back and moan loudly.
"Re-Ren--"
You whimpered as his lips made contact with your hot skin, suckling the perfect skin, leaving beautiful purple and red marks that were easy to hide but satisfied him to know they were there along your perfect complexion.
He kissed his way down to your breasts, teasingly, his fingers hovered over the strap, in which you emitted a low whine, you were so sure you could feel him smirk against your skin.
"Rengoku, please, please" you whined, his name falling from your tongue as if it were a prayer, and he would happily indulge you.
He unclasped your bra, you thrusting your chest upwards as if you were trying to tell him to just take it off already and so, he very, very happily did.
He tugged your bra off and took a moment to admire your chest, your boobs were perfect, they really were, he groped them gently, his hands fit them well, his hands were rather large.
You let out a cry as he flicked the sensitive bud at the centre, causing him to question whether you were alright, to which you obviously were just fine, you weren't someone who would crumble from a little pleasure.
And so, with that, he took one sensitive, needy nipple into his mouth, swirling his tongue around it and suckling it with expertise.
You let out a shrill cry from the action as he urged you to keep it down; and that it would all be okay; and to relax and enjoy yourself.
The knot in your stomach felt like it was tightening, and you were feeling a sense of warmth pool in your gut, but just before you could release, he pulled away, causing you to whimper, but soon silencing you as he kissed down your stomach and whispered sweet words against the soft skin.
He made his way to your panties, and he gave no room for any words to be spoke, or even any protests, which was rather rare for him to do, his tongue darted out of his mouth, locating and licking the sensitive bundle of nerves immediately, in which made.you bite your palm.
"Rengoku, please"
"Please what, my little flame?" He purred, his voice dripping with honey.
So he was a tease in bed?
"Please touch me, please"
He smiled up at you, and, all whilst maintaining eye contact, within the blink of an eye, he literally ripped your panties off of your figure and began to press gentle kisses and love bites to your inner thighs and around your pussy, before paying special attention to your clit.
It throbbed in his mouth, he could feel it pusle as he pressed his tongue against it, swirling it in his mouth and sucking the sensitive little bud.
You barely contained your screams, how could he do such a lewd act whilst maintaining eye contact.
"Focus, little Hashira" he purred
"O-On what?"
"Your breathing."
He was right.
Your breathing was laboured and heavy, and it only quickened when he pressed a finger against your sopping cunt and pushed in, applying pressure to your sweet spot immediately causing you to gasp.
"Listen to me, I need you to focus on your breathing, god forbid the others walk in on us commuting such a vile act of passion"
You nod, agreeing to atleast try, as you began to control your breathing, but he put you to the test whilst pushing one more finger in, and teasing your oversensitive clit at an inhuman pace, causing you to clench your teeth to suppress the moan that was stuck at the bottom of your throat.
That same heat that coiled and boiled in the pit of your stomach resurfaced once again with a vengeance
"You gonna cum, little flame?"
Before you could respond, your walls clenched tight around the Hashira's fingers, cumming all over them, a glistening, pure liquid which he lapped up with his tongue eagerly, sending shivers back down your spine all over again.
"You're ready"
You soon understood what he meant when he arose from his position and gave you a clear view of the large tent that formed in his pants.
He leant down and caught your lips in his, a passionate kiss ensued, a chase between your tongues, your skin burnt up and you felt as in you were engulfed in flames of love; and passion.
"I love you so, so much" he huffed against your lips, pulling away for a brief moment of air and biting his lower lip, before you could lament his words back to him he caught your lips again,
"I know, baby girl, I know"
He moaned into the kiss, slipping his belt off hastily with ease along with his boxers and presenting himself to you in all his glory.
You swallowed thickly as you stared at him.
His size...
He was thick, veiny, hard and dripping with inhuman amounts of precum.
"Do you think you can take me all?" He muttered against your lips, wrapping your legs around his hips and aligning himself with your entrance, he was so big that he would definitely be a tight fit.
"I-I don't kno--" before you could finish your sentence, he slammed into you, his hips kissing yours immediately as you were split in half by the sheer size of his cock, causing you to bite your lips and scream against his chest as he help you and begun to rock his hips into yours, slowly at first, but his pace increasing steadily.
Soon enough, he was pounding you at an inhuman pace, moaning as your velvety walls maintained a vice grip around him, he looked so handsome like that.
He pressed your legs against your breasts, folding you in half and allowing himself to pound impossibly deeper into you, hitting that one spot that made you go insane.
You let out a yelp, calling his name.
"Fuck, fuck, so close" he groaned, his voice low and in hushed whispers.
The door slid open to reveal none other than the stone Hashira himself, Gyomei.
Your eyes widened, the man scanning the room and taking note of any little sound he could hear, but Rengoku didn't seem to care, he just continued to pound into you like normal.
He held your hands in his as he called out your name.
'Shit, shit, why isn't he pulling out, Gyomei is right there!''
You whimpered and thought to yourself.
He leant in next to your ear and whispered;
"Just a little more, I'm so, so close, just take me a little more, take my seed inside of your womb, little Hashira" and with one final crash of your hips, it happened, his cum filling you, an inhuman amount of cum, so much that as he slid out, it oozed out of your cunt.
It was hot, thick, heavy inside of you, you bit your lower lip as his fingers worked your clit to your second orgasm, staring you intensely in the eyes as it happened.
When you finished and calmed down from your high, he pressed his forehead against yours', embracing you tightly.
Unbeknownst to the both of you, Gyomei had caught wind of who it was.
"Y/N! And!.... Rengoku? What may the two of you be doing here? And why did you not say anything as I called for Y/N's name?"
"Ah! Gyomei!"
Rengoku answered in the tone he usually would, which honestly shocked you.
"My apologies, dear friend, me and Y/N were caught up in 'training' and we couldn't hear you during the 'heat of the moment'!"
"I see." The stone Hashira nods.
"That must explain away the odd smell coming from the two of you."
"Yep!"
You replied quickly, causing him to raise an eyebrow at you.
"Well, I suppose I'll leave the two of you to it then."
You and Rengoku hummed as confirmation as the stone Hashira left, smiling at eachover and embracing eachover.
"Thank God it was him and no one else, now, let's go sort ourselves out before someone who isn't Gyomei finds out about our devilish acts." You nod, your legs wobbling as the flame Hashira grasps your hand.
"Need any help, little flame?"
"Please" the both of you chuckled, heading to the bathroom to clean yourselves off.
