Chapter 1: Douma x Shinobu

Chapter Text

Kimetsu College Academy was filled with secrets and lust as it gleamed with false purity.
Vice President, Shinobu Kocho, buried her secret in an empty, dark classroom. Her skirt rucked to her waist, legs over Douma’s shoulders, his cock splitting her open while the windows screamed with wind.
“Ugh, at least close the windows, you asshole!” Shinobu groaned, her voice a husky thread fraying at the edges, even as her hips betrayed her.
"Hehe, where's the thrill in that?” Douma's laugh slithered out, low and sinful, his rainbow-hued eyes glinting with predatory glee.
Shinobu hated him.
She hated him.
She hated him.
His hands roamed greedily, one palming the pert swell of her breast through her half-unbuttoned blouse, thumb circling her nipple until it pebbled hard and aching. The other gripped her glutes, fingers bruising as he drove deeper, his girth splitting her open with each savage thrust.
“When are you going to just cum already?” Shinobu fumed.
“When your pussy begs for it.”
The obscene moaning of her arousal echoed off the walls, her cunt clenching greedily around him despite the venom in her veins.
She hated him.
More than the gnawing poverty that clawed at her heels. This rainbow eyed demon caused havoc as the person who would bully innocent students with a smile on his face. He was feared by many and was known to even commit crimes that were covered up by his money. Yet here she was, thighs quivering, pussy weeping down his shaft as he fucked her against the cold wall.
Douma was rich. That was why she needed him despite her utter disgust of him. Douma had sniffed out her desperation. Her tuition piling like snowdrifts, the threat of expulsion looming over her. Her secret shame, the one that could shatter her polished facade and tarnish her dear sister’s memory forever. Her dear sister, who had been a symbol of elegance and strength that everyone praised had left behind a legacy she had to follow behind. In exchange for his financial help and to keep her situation a secret, she gave him what he had asked for. Her flesh. Again. And again.
“Ah, Shinobu, honey your pussy feels so delicious,” Douma moaned hot against her ear, his breath a humid caress that sent shivers racing down her spine. “Bet you dream of this when you're touching yourself alone at night."
"D-Don't... call me honey," she hissed through gritted teeth, words fracturing into whimpers as his cock hit that devastating spot inside her, grinding slow and filthy.
“Aww, but honey fits you. Babe? Do you prefer that?”
“Enough talking.”
Her walls fluttered, traitorous sparks igniting low in her belly. She clawed at his shoulders, but he only laughed as he thrusted harder and faster. The wet slap of skin on skin drowning out the wind that blew into the empty room. Her climax kept building, unwanted but inevitable. Douma sensed it, his pace turning brutal, hips snapping with possessive force.
"Cum for me, baby. And then I’ll cum after." Douma reached down and began circling her clit.
She shattered with it, orgasm ripping through her like lightning, her cry muffled against his neck as her pussy spasmed wildly. Douma pounded one last time before erupting hot jets of cum inside of her.
"You-you said you wouldn't cum inside, you demon!" Rage boiled at her chest as she shoved him off with trembling hands, a gush of his seed trailing down her thighs.
Douma blinked at her, feigning wide eyed innocence as he tucked himself away, that infuriating smile curling his lips. "Did I? Ha, must've slipped my mind amid all your squeezing."
She yanked her skirt up, buttoning her blouse with jerky fingers, and searching the floor for her panties.
“Same place, same time tomorrow?” he asked.
"Just keep your mouth shut, asshole," she spat, storming for the door without a backward glance, his cum still slick between her legs.

*******
Shinobu slipped into the student council chamber with careful silence, her body still remembering Douma’s touch. She claimed her seat at the polished oak table, surrounded by the academy's elite. Gyomei Himejima, the towering president, loomed like a benevolent mountain, his blind eyes seeing more than most. Kyojuro Rengoku, public relations officer, radiated sunfire energy, his golden hair a halo of unyielding optimism. Obanai Iguro, treasurer, slouched with serpentine grace, his heterochromatic gaze sharp as a hidden blade. And then there was Giyuu Tomioka, secretary who was like a dark-haired enigma.
Shinobu's pulse quickened as Giyuu rose to deliver his report. His voice was low and monotone. Still, he captured her with his devastating looks. His broad shoulders straining his uniform and those deep blue eyes tugged at her core. On paper, he was perfect. He was top of his class, with impeccable manners and a skilled swordsman.
But that was all she knew of him. He was perfect and imperfect at the same time. A lonely person who ate in shadowed corners and wandered the hallways alone. He spoke only in student council meetings, but outside of that, he remained silent.
She imagined being the one to bridge that gap. To be the one he would open up to. She imagined them sparking up a conversation but then doing more than just bare talking. But then Douma slithered into her thoughts with that smug grin of his. The way he filled her up, marking her with his seed. He was like the polar opposite of Giyuu. He was pure evil, and she loathed that evil with every fiber of her being.
Despite his evil, she couldn’t deny that it felt good when he would thrust into her. Did she crave the degradation? Her sister's face flickered in her mind. Kanae, who was everything she had ever wanted to be, would hate her if she found out she had been sleeping with a demon.
"Shinobu? Shinobu?" The voice yanked her from the abyss. Gyomei's deep voice, gentle but firm, had got her out of her head. She blinked, heat flooding her face as every eye turned her way.
Obanai's scoff sliced the air like a whip. "We’re waiting on your report, Vice President. You seem too busy daydreaming about God knows what.”
Her cheeks burned hotter. "Ah, sorry, I... lost my focus." She straightened, forcing poise as she rifled through her notes. She tried to ignore the sticky feeling that she felt down there.

Chapter Text

The lunchroom buzzed with chaotic voices mixed together. But beneath it all, desires simmered like hidden blades.
No one's burned as fiercely as the flame between Tanjiro Kamado and Kyojuro Rengoku. Tanjiro sat wedged between his ragtag crew: sister Nezuko, fresh-faced and wide-eyed as a first-year with textbooks beside her tray; Zenitsu Agatsuma, blond spikes quivering with perpetual panic; and Inosuke Hashibira, boar mask shoved back to reveal a feral grin and wild black curls.
"Nezuko, Nezuko, look what I can do!" Zenitsu's voice cracked with desperate flair as his body ignited with golden lightning as a display of his affection.
“Ha, that’s nothing compared to this,” Inosuke said, standing up and punching a whole through his table.
Zenitsu screamed. “Do you know how much that will cost?”
Nezuko smiled politely.
Usually, Tanjiro would giggle at his friends’ silliness. But now, his world had narrowed to the far table where his boyfriend of one year sat. Rengoku, his boyfriend, was like a flame-haired god among mortals. His golden eyes crinkling mid-laugh as he bantered with Mitsuri Kanroji and Tengen Uzui.
Tanjiro's pulse quickened at the memory of their first time.
Of his first time.
Rengoku had engulfed him with his warmth as he devoured his body. Every inch of him trembled from Rengoku’s every thrust. His thick cock stretching him full.
Tanjiro’s face turned pink. He shouldn’t be thinking such obscene things in such a public place. What if he got too excited.
Tanjiro's mind drifted unbidden to the day it all ignited. Their first meeting was like a spark that had blazed into this all-consuming flame. He remembered being mocked as a freshman for being an ‘overly passionate freak’. He had dreams of being the best in all of his lectures, making many friends and making his loved ones happy. But demons would use those dreams as weapons against him, viewing them as a sign of his weakness. Demons would shove him against lockers and taunt him when one day Rengoku stood in front of him to protect him from the demons that made his life a living hell. Rengoku became his hero that day and someone he deeply admired. Admiration turned into a desire for more. He remembered at nights he would fantasize about a naked Rengoku pressing against his own naked body, insisting that he open his hole for him.
Tanjiro blushed even harder at the memory, but it all went away when he noticed Mitsuri leaning in closer, uniform blouse straining over the generous swell of her breasts, brushing Rengoku's arm in a way that sent a possessive heat coiling low in Tanjiro's gut.
Rengoku was popular. He knew he was popular and that every girl and boy wanted him. But this was different. The way Mitsuri’s breasts smothered over Rengoku’s arm and how his boyfriend didn’t make any attempt to pull away.
Tanjiro hated the feeling, because he wasn’t a jealous person.
Or so he thought.
******
Lectures were over and now Tanjiro and Rengoku’s dorm room air hung thick with the musk of sweat and need. Rengoku's hands were already on him, broad palms holding onto Tanjiro's waist, hauling him back and forth.
Tanjiro hovered over the mattress, a dirty moan spilling from his lips as Rengoku thrust into him. His cock went deeper, each plunge a confession of longing.
“I’ve been starving for this all day,” Rengoku whispered in his ear. Their mouths clashed in a messy, devouring kiss with their tongues tangling slick and desperate.
Their lips only separated when Rengoku’s hips drove into him. Pre-cum smeared sticky trails across sweat-slicked skin. His boyfriend’s girth stretched him to the brink, that thick vein pulsing against his walls, grinding over that electric spot that made his eyes roll back in pleasure.
Tanjiro's fingers clawed at his pillows. “Mmm, babe, I want you to cum inside of me,” he moaned in pleasure, gasping when his boyfriend took things to the next level and began pounding harder and faster.
"Say it again."
"Please..cum inside of me."
“Okay, I'm gonna give you what you asked for,” Rengoku could barely breathe as his balls slapped heavy against Tanjiro's ass, the obscene schlick of lube and arousal filling the room.
Tanjiro climax felt inevitable, ropes of cum splattering his chest. His cry echoed raw and broken, walls spasming wildly around Rengoku's cock. His boyfriend followed as he erupted hot, creamy cum inside Tanjiro's depths. They both collapsed as his boyfriend’s weight became his blanked, chest heaving against Tanjiro’s back.
"I really can’t get enough of you." Rengoku breathed heavily, nuzzling into the crook of Tanjiro's neck.
They lay there in silence for some time as their bodies cooled from the heavy workout. Even with the silence and the romantic air between them, Tanjiro could not stop thinking about earlier.
Tanjiro's chest tightened, words tumbling out before he could think them through. "You've been... getting closer to Mitsuri lately, haven't you?"
Rengoku stilled, propping up on his elbows with a puzzled furrow between those bold brows, his softening cock slipping free from his wet hole. “Mitsuri? We’ve always been close.”
That wasn’t what he wanted to hear, jealousy now gnawing at his edges. “How close?”
“What…do you mean? We’re friends.”
Stop, this isn’t you, Tanjiro told himself. Smile. Act like everything’s okay.
Rengoku then cupped his jaw with tenderness, and slowly slipped his tongue through Tanjiro’s lips, pouring reassurance in the form of a kiss. Tanjiro sank. The kiss was enough to erase every bit of jealousy he felt for just a moment.
“I love you,” Rengoku whispered.
Tanjiro smiled. “I love you too.”
What was he thinking. Even if Mitsuri wanted him, he had nothing to worry about.

Chapter Text

Moonlight slanted through the dorm window like a silver blade, carving shadows across Mitsuri's rumpled sheets. The air hung heavy with her ragged breaths as she jerked her fingers inside of her pussy. Lately, horniness had hit her at random moments. Even during lectures, her fantasies did not end with rough hands pinning her down, cocks thick and demanding splitting her open.
She’d imagined snagging someone to devour her whole. She craved the burn of something dangerous. She would fuck the whole school if she could. Mitsuri's fingers delved deeper, plunging into her soaked pussy with a wet schlick that made her hips buck off the mattress. She was sprawled wide, thighs splayed shamelessly, uniform skirt rucked up around her waist, panties shoved aside like an afterthought. Her free hand kneaded one heavy breast through her blouse, pinching the nipple until it throbbed, a sharp jolt arrowing straight to her clit.
"Oh wow," she moaned, voice husky and broken, head lolling back against the pillows. Her walls clenched greedily around her fingers, fluttering with each curl and thrust. Juices coated her hand, dripping down to stain the sheets in dark, guilty patches.
Her mind raced through a carousel of faces, each stoking the flames higher. Rengoku's arms wrapping around her waist to hoist her up, impaling her on that sun-hot cock until she melted. Gyomei's body and those massive hands spanning her hips, spreading her wide for a slow, devastating grind that would wreck her. And Obanai...
The thought remained in her mind for some time. Obanai was always gentle with her. His rare smiles were always saved for her, cracking the mask he wore with others. The thought of him made her pussy throb. She imagined him above her, mismatched eyes blazing, cock hard and unyielding as he pinned her wrists, whispering filth in her ear. Her whimpering at his every request.
Suddenly, the door creaked open. Mitsuri’s hand froze mid-thrust, buried deep inside her glistening cunt. Shinobu, her roommate, appeared at the door.
"Shinobu! I…I thought you wouldn't be back this soon!" she yelped, yanking her hand free with a lewd, suctioning pop that echoed obscenely in the sudden quiet.
Shinobu chuckled. “It’s fine, Mitsuri. Just... finish up. I'll wait out here,” a faint flush creeping up her neck, but somehow there was no judgment.
Mitsuri's face burned as she scrambled to find her panties. She then dashed to the sink to wash off the evidence and any lingering scent that stained her body.
What if she'd seen how wet I was?
When Shinobu finally slipped back in, Mitsuri was bundled in her robe, knees drawn up on the bed like a chastised kitten. She dropped to her knees in a theatrical beg with her hands clasped, green eyes wide and pleading. "I'm so sorry you had to see that. I swear, I thought you'd be out hours longer like you’ve usually been doing these days.”
“Like I said, Mitsuri. It’s okay.”
“If you say so.”
The two remained quiet for a while.
“You’re hiding a secret boyfriend, aren’t you?” Mitsuri began in an attempt to remove the awkwardness.
Shinobu's laugh bubbled out, light and genuine, easing the knot in Mitsuri's chest. She perched on the bed's edge, waving it off with a delicate hand. “Nope. I’m just being a good civilian.”
“Come oooon! You’ve been sneaking late at night which you never used to do.”
“Studying. That’s all it is.”
Mitsuri was not convinced, especially with the way Shinobu tried avoiding eye contact.
“What about you?” Shinobi inquired.
“What about me?”
“Obanai. He likes you. He really likes you. I think everyone can see that.”
“Yeah…he does. But, I’m not ready for a relationship. I want to fuck, Shinobu.”
Shinobu eyes widened with amusement. “Elaborate.”
“Well, I just have this strong urge to fuck as many people as possible. Every minute of every day I just keep having these sexual fantasies and with every fantasy there’s always someone different.”
“That’s surprising because you’ve always spoken about finding your one true love. You’re such a romantic.”
“I am, and that’s still my end goal, but right now, I want to explore. Is that…bad?”
“Of course not. It’s okay if you want to explore your desires and if anyone going to judge you for it, then fuck them.”
Mitsuri squealed and hugged Shinobu in a tight embrace.
"Okay, so this is what I have in mind. I’m first going to go for Rengoku. Just being around him makes my knees jelly.”
"Rengoku's a sweetheart., but I’ve heard he’s with Tanjiro."
Mitsuri pouted. "Are you sure? Rengoku never seemed to mind my tits being all over him. But Tanjiro is such a cutie pie! Maybe we can have a threesome!”
Shinobu giggled. “That would be interesting to see.”
“I was thinking about going for Tengen next. He’s such a flashy hunk. But he seems already busy with his three girlfriends and the whole school wanting a piece of him.”
“He is quite handsome.”
“I know right! So sexy!”
“Who’s next?”
“Gyomei. He just looks like he has a huge cock.”
“Oh, no, that’s my mentor, Mitsuri. I can’t be imagining him in that way.”
“Haha, sorry.” Mitsuri then shifted, sitting crossed legged on the bed. “There are two that I probably would never go for though. Sanemi because he scares me and Giyuu because you like him.”
Shinobu blushed. “Why do you think I like him?”
“You talk about him a lot.”
Shinobu did not confirm or deny.
“And sorry to say this, but he’s also kind of depressing. I like upbeat guys. I was also thinking about dabbling with a woman or two.”
“I see. What about Obanai?”
"Obanai..." She trailed off with the room dipping into the same silence as before.
Shinobu's stare was gentle but probing. "Sounds like Obanai might be the one.”
Mitsuri’s heart stuttered, fast and fierce. “Yeah… but if we get together now, I’ll end up hurting him. I want to be with him…just not now.”

Chapter Text

Zenitsu crammed his pillows over his ears as the sound and the scent of sex filled the dorm room. Tengen, that flamboyant bastard of a roommate, was railing three girlfriends on the king-sized bed mere feet away. The sounds crashed over him like a tidal wave: rhythmic hips slamming home and wet mouths devouring cocks and cunts. Their moans twisted into something inhumane.
"Fuck, Tengen, harder!" one of his girlfriends begged, her voice fracturing as another slurped greedily around his shaft, lips popping free with a filthy smack before plunging back down.
“Ha, you don’t have to ask me twice,” Tengen responded, with a tone of overconfidence that annoyed Zenitsu.
Zenitsu's stomach churned with bitter envy. The audacity of Tengen to not only have three girlfriends, but to also be making love to all of them while he was inches away on his bed. It was also the ease Tengen seemed to have with women that infuriated Zenitsu more.
Zenitsu would struggle to even have one person look his way. Nezuko, his crush, would only smile politely at his advances. He wasn’t blind. He knew Tengen was probably the best-looking guy in Kimetsu College Academy. His swaggering grin and flawless arms added to his charm. But Zenitsu would like to think he wasn’t far off in terms of looks or even charm.
He wasn’t ugly. At least, that’s what he liked to think.
The polyamorous harmony continued with one of his girlfriend’s moans reaching a peak, “Tengen! Ugh, Tengen!” her voice echoed throughout the room without shame. “Fill me up, please.”
Zenitsu could hear lips smacking against each other and bodies shifting around. He could feel his traitorous body ignited, cock straining against his lower fabric. There was pre cum leaking at the tip of his cock. He couldn’t help wanting to be touched at that very moment since the moans triggered his unmet needs.
He fought the urge to stroke himself. He wouldn’t dare give that bastard Tengen such an honor. If only Tengen wasn’t his roommate, he wouldn’t have to listen to the sounds of sex every night. Someone like his best friend, Tanjiro, would have respected him. He would be sleeping peacefully if Tanjiro was his roommate, dreaming of Nezuko.
Finally, everything came to a halt when the four reached their limit, groaning from pleasure. They then collapsed on the bed, gasping for air.
****
Dawn clawed through the windows as Zenitsu shuffled in from his shower, towel slung low, only to freeze as Tengen entered completely buck naked.
Zenitsu's scream ripped out, shrill as shattering glass. “W-What the hell are you doing? Put on some goddamn clothes!”
His eyes narrowed down to the impressive length that were between Tengen’s thighs, thick and veined.
Tengen’s brow arched in lazy amusement, hands on hips framing his dangling prize like a trophy. "All my clothes are wet so I’m free balling. What's the big deal, peepsqueak? I’m gonna take a shower anyway.”
"The big deal? You're naked! Swinging that... that thing around like it's nothing!”
Tengen's grin turned wolfish, stepping closer until the heat of his body invaded Zenitsu's space. "Does this turn you on or something?”
Zenitsu's face ignited. "I swear, you're so full of yourself. Like that small dick of yours could turn anyone on, let alone me!"
“Excuse me, peepsqueak? Did you just call my dick ‘small’?”
There were demons like Akaza and humans like Sanemi on campus that scared him. But, Tengen, despite his tall and muscular build, never made him feel that way. “Look, I’m tired of you showing off your girlfriends and having sex when I’m literally right there. As your roommate, I demand-”
Zenitsu’s stopped when in a blur, Tengen snatched his collar, yanking him upwards. “Who are you to give a flashy guy like me orders?”
Even now, he wasn’t scared of him.
“You-you should really put me down. I’m not the peepsqueak you think I am.”
“Well, you’re definitely not a giant.”
“And neither is your dick.”
“This monster’s got more girth than your whole damn arm.”
He was right. It was girthy. But he wasn’t going to give him the pleasure of acknowledging it.
Tengen seemed to have slipped from the slippery floor because he then lunged, shoving Zenitsu back with Tengen’s hand palming the back of his head to safely lessen the damage it would have caused if it had hit the floor.
Zenitsu blushed when he realized the awkward position they were in. Zenitsu’s legs had spread open with Tengen’s naked body between his thighs, hovering over him. His towel had slipped off from the fall so Zenitsu was also fully naked. Their eyes locked as their cocks brushed against each other.
The silence stretched thick and electric. He wasn’t sure what to do at that moment since this was his first time ever being in such an intimate moment with someone. Zenitsu’s heart hammered so hard, he was sure Tengen could hear it.
Tengen’s hips surprisingly then began to roll slow, his cock grinding against Zenitsu’s. The friction was maddening. Zenitsu bit down on his lower lip willing himself not to moan but the sliding against his cock was just enough for his moan to slip accidentally.
When Tengen spoke, it was like a gravel whisper. "Can I put it in?"
Heat flooded Zenitsu's veins with a treacherous curl of want that terrified him. “Get off.” He shoved Tengen off with frantic strength and left the bathroom with the door slamming behind him.

Chapter Text

The wind on the rooftop was gentle, almost kind, as it lifted the loose strands of Giyuu’s hair and carried them across his cheek. He sat cross-legged in the exact corner he always chose, back against the concrete ledge, bento open on his lap: plain rice shaped into a perfect mound, three slices of pickled radish arranged like pale petals. Each bite was deliberate, quiet, the way he had learned to make every part of himself quiet.
Solitude had become a habit so old it felt like skin. Below, the courtyard rang with voices, and laughter, but where he sat only had the wind and sky and the faint smell of salt from the distant sea.
He would often eat lunch alone, because he had no one to share the moment with. But it wasn’t for lack of trying. The truth was that his words never agreed with him. When he tried to make friends, his words would betray his intentions. Eventually, people began to see him as either arrogant, snobbish or depressed.
They weren’t entirely wrong about him being depressed.
Once, there had been a dear friend of his named Sabito who turned silence into shared stories and tears into laughter. The only time he had ever laughed was with Sabito. But when his friend died, it was like his laugh died with him.
As the wind blew gently, Giyuu could feel the presence of his friend.
“Hey, Mr. Giyuu! Have you seen Zenitsu around?”
The voice snapped him back so suddenly he almost dropped his chopsticks. Tanjiro stood at the top of the stairs, head tilted, burgundy hair catching the sunlight like spilled wine.
Giyuu blinked. He hadn’t even heard the door open.
“No,” he said. The single word scraped his throat raw; he hadn’t spoken all morning.
“Oh. We were supposed to eat together.” Tanjiro rubbed the back of his neck, sheepish. “Guess he ditched me.”
Giyuu looked down at his rice again. “He’s not here.”
He waited for retreating footsteps. They didn’t come. Instead, Tanjiro crossed the rooftop in three eager strides and dropped beside him, legs folding neatly, bento already open on his lap.
“Then I’ll eat with you instead, Mr. Giyuu!”
The words hit like a small, unexpected sunburst.
“With… me?”
Tanjiro’s smile was wide and uncomplicated. “Yeah. Why not?”
For a while it was awkward. Tanjiro talked (about training, about Nezuko’s new ribbon, about Inosuke trying to fight the vending machine again), and Giyuu answered in short, careful sentences. But Tanjiro never seemed to mind the pauses. He filled them the way Sabito once had, only softer and warmer.
“Do you come here a lot Mr. Giyuu?”
“I do.”
“Hmm, maybe I should come here often too. It feels so peaceful here.”
“There’s no need for that. You don’t have to force yourself to stay. You can leave.”
Tanjiro tilted his head. “I’m not forcing myself. It’s fun talking to you.”
Giyuu felt something shift inside his chest, like ice breaking. He looked down quickly before Tanjiro could see the hopeful expression on his face.
“You know, I’ve been looking at your haori. The design is pretty cool,” Tanjiro beamed.
Giyuu’s fingers tightened on his chopsticks.
“Half of it… belonged to someone,” he said, voice barely above the wind.
“Someone important?”
Giyuu nodded once. “His name was Sabito.”
The name left his tongue like a confession. He hadn’t said it out loud in years.
Tanjiro’s expression softened, understanding without needing details.
“You must have really loved him,” he said gently. “You still carry him with you every day.”
Giyuu stared at the checkered half of the haori, the fabric worn soft from years of being close to his skin.
Yes.
That was the word for it.
He wasn’t just his dear friend. Sabito had been the first person to make Giyuu’s heartbeat louder than his fears. The first person he had ever wanted to reach for and never quite known how.
His first love.
*****
A month slipped by almost without Giyuu noticing.
Every school day during lunch the rooftop door would creak open and Tanjiro would appear, bento in hand, smile already in place. They never planned it; it simply happened. Giyuu would already be there, back against the wall, and Tanjiro would settle beside him as if the space had always belonged to him.
Tanjiro told stories and Giyuu listened. Sometimes he offered fragments in return: the way Sabito used to flick water at him during summer training until Giyuu finally laughed so hard he couldn’t breathe. Those memories used to ache. But spoken aloud in Tanjiro’s quiet company, they felt lighter, like stones smoothed by a river.
And Tanjiro smiled at every one, bright enough to make Giyuu’s mouth curve. Each time it happened he felt the ice inside him crack a little more. Words came easier; silence grew comfortable instead of heavy. And beneath it all, a new ache bloomed, low and urgent.
Tanjiro would lean in to point at something in Giyuu’s bento, and their shoulders would brush. The contact was brief, accidental, but it lit Giyuu up like a struck match.
At night, alone in his room, the wanting became unbearable.
He imagined Tanjiro there with him, back pressed to Giyuu’s chest, Giyuu’s arms locked around his waist like he’d never let go. He pictured sliding a hand up Tanjiro’s throat, tipping his head back, and kissing him until neither of them could breathe.
In the fantasy Tanjiro’s mouth was soft and Giyuu would kiss him slow at first, almost reverent, then harder, hungrier, until the gentleness burned away. He would lick past Tanjiro’s lips, claiming every small gasp, swallowing every sound. Tanjiro would open for him instantly, tongue sliding against his, hot and wet and perfect.
Giyuu imagined pinning him gently to the mattress, hips slotting together, the drag of fabric doing nothing to hide how badly they both wanted. He would suck on Tanjiro’s lower lip until it was swollen and red, then soothe it with his tongue, only to bite again because the broken little moan Tanjiro made was the most beautiful thing he’d ever heard.
When he pulled back just enough to breathe, Tanjiro’s eyes would be dark, dazed, lips glistening. He would whisper, hoarse and pleading, “Again, please,” and Giyuu would give in every single time, kissing him deeper, slower, filthier.
*****
The rooftop was quiet except for the wind and the soft clink of chopsticks against bento lids. Tanjiro had been unusually subdued all lunch, picking at his rice, eyes fixed somewhere past the chain-link fence. Giyuu noticed the way his fingers kept tightening around his chopsticks, loosening, tightening again.
Finally, Tanjiro spoke, voice smaller than usual. “Giyuu…have you ever felt…jealous?”
Giyuu paused mid-bite. The question hung between them like a sudden drop in temperature.
“Why do you ask?”
“I’m just…curious.”
Giyuu set his chopsticks down. He thought of crowded hallways, of laughter he was never part of, of arms slung around shoulders that weren’t his, of mouths brushing in corners he pretended not to see. He thought of the hollow ache that always followed.
“Sometimes,” he said quietly.
Tanjiro’s gaze flicked to him, sharp and searching. “Do you think it’s wrong? To feel that way?”
“No,” Giyuu answered without hesitation. “It’s human.”
Tanjiro nodded slowly, as though the answer settled something and unsettled something else at the same time. He stared at his bento for a long moment.
Giyuu watched the tension in Tanjiro’s jaw, the way his shoulders curled inward. Over the past weeks they had learned to sit inside each other’s silences, to offer pieces of themselves without being asked twice.
“Do you want to talk about it?” Giyuu asked, softer than the wind.
Tanjiro exhaled, shaky. “It’s… about my boyfriend.”
The word hit Giyuu like a fist to the sternum.
Boyfriend.
His mind blanked for one stunned second, then filled with static.
“I have this awful feeling he’s cheating on me,” Tanjiro continued, voice cracking on the last syllable. He laughed, thin and humorless. “Stupid, right?”
Giyuu couldn’t breathe properly. The rooftop suddenly felt too small, the sky too close. “You have… a boyfriend,” he repeated, the words foreign and heavy in his mouth.
Tanjiro looked up, eyes wide with sudden realization. “Wait, you didn’t know?” A nervous, apologetic smile flickered across his face. “I thought everyone knew. I’m sorry, I should’ve said something sooner. His name is Rengoku. Rengoku Kyojuro.
