You're returning to the Butterfly Mansion after a mission and as you're about to walk through the main gate you hear a familiar voice call out to you.
"Ah! Y/N-chan, darling~! It turns out you're here" He exclaimed. Turns out he's been looking for you. He takes excited steps towards you.
"What are you doing here?! If anyone catches you-" You whisper loudly, turning to facing him. You both know a romance between demon and slayer is strictly forbidden.
Douma's previous encounters with you made him feel something he's unfamiliar with and to him that's all that currently matters. His cheerful grin widens as he dramatically presses a finger to his lips, the iridescent kanji in his eyes glint mischievously.
"Shhh~ Don't be so loud, my little slayer. I'm just here to check on you after all.." He purrs, taking another step closer while fanning himself.
"You're asking to get yourself killed," you warned, not as a treat, but as a concerned partner.
He gestures toward your stomach with his golden lotus fan.
"…Our precious little secret is growing quite fast now, isn't it? Two whole months! I've been counting."
Your hand instinctively goes over your stomach.
"Yes.. almost 10 weeks now. You've been keeping track..?" Your eyes look up curiously at his.
"Of course I have. Every second, every minute, every hour. It is our child, after all.." He whispers, gently placing his free hand over yours oddly full of affection.
"How have you been feeling?"
"For carrying a child that'll be born half-demon I'm doing okay, good even. Just more tired and already making my job difficult.." You move your hand out of the way for him to feel and have this moment.
His eyes shimmer with something unreadable, tender perhaps.
"Good? That's wonderful~ Though I must say… you shouldn't be working at all. Not in this state." He leans down slightly, a glimpse of his true dangerous demon nature shows beneath the gentle facade.
"If it becomes too difficult… if anyone suspects anything… I could always make them disappear."
"You know I can't just intentionally let you eat a comrade.. and that's why it's hard to just retire out of the blue, it'll cause suspicion." You're serious even though you're speaking as softly still.
"Ohhhh~ So you're worried about your precious comrades?" Douma laughs out airy and melodic as frost begins to form delicately around his feet, tilting his head with mock thoughtfulness.
"But darling, they're the ones who would eat you alive if they knew what was growing inside you."
You hate knowing when he's right about something and don't resist when he pulls you closer.
"Don't try to justify it."
"I could be so… creative. Maybe just one tiny 'accident' during training? A little push off a cliff?" He smiles falsely sweetly, the ice beneath your feet spreads slightly in intricate lotus patterns.
"…Or would that make my sweet Y/N too nervous~?"
You watch him closely. Would he actually do that? Just to make you quit being a slayer?
"You're willing to cause possible harm to the baby?"
Douma's expression takes on a more serious tone at your quiet question before it softens more sincerely again, looking down at your stomach. He fingers sprawl out.
"No. Of course not. I would never dream of harming our little one. That's why I'm worried about you. You're not just carrying any child, it's mine you're carrying. And you're out there fighting…" His eyes meet yours again pleading.
"Not only am I fighting which each mission I'm assigned but it's against your kind. The irony.." Your breath showing from frost. You take his worry into consideration.
"Would it put you a little at ease if I were to say that I'm planning to stop once I actually started showing?"
"You… you're really planning to quit once you start showing? That's… That's wonderful~" Douma breathlessly laughs, there's genuine relief.
"You have no idea how many nights I've spent worrying about you… and the baby. Promise you won't try to push yourself too much?"
"I promise. I just.. honestly have other things heavy on my mind that concern me.."
He tilts his head curiously with concern.
"Other things, darling? What is it? What's troubling you?"
You take a breath gathering your thoughts, lowering your eyes.
"Carrying a demon worries me.. like.. what if later on normal human food doesn't satisfy anymore and I start getting a hunger.. if you catch what I'm saying.. and.. what if I can't carry full term.. what if my human body can't take it.."
"Those are all… very valid concerns." His expression softens even more then wraps his arms around your waist, pulling you closer in a gentle embrace. He's reassuring despite the situation.
"But… you're not alone in this. I'll be beside you every step of the way, making sure you get everything you need. And as for the risks…"
"..yes..?" You ask curiously watching his eyes trail down to your stomach again.
Douma presses his forehead gently against yours. The cold of his skin contrasting with the warmth in his tone.
"If you need blood… I'll bring it. If you get hungry for something unnatural… I'll find a way to make sure our little one gets fed. And.." He pulls back to look at you more seriously.
"And if your body struggles… then we stop. No more missions, no more pushing yourself. We go straight to hiding until it's safe. Though.. I might have trouble resisting a taste or two when that time comes~"
The possible thought of even getting cravings like a demon makes your stomach want to twist. You find that rather disgusting. And even though you find his concern absolutely endearing for being what he is you just couldn't hold back the playful scoff that followed with a smile.
"Of course temptation is the first thing that comes to your mind.."
"Darling… did you expect anything less from a demon?" He lightly laughs back, giving your waist a gentle squeeze.
"You got me there.." Your hand comes up to touch the side of his face.
"I'm just scared is all.. this isn't exactly the most common thing to happen.. and most don't even get this far because majority of the time demon and human DNA don't mix right.."
"You're not wrong… the odds are against us. You know that. I know that. But still… We're going to make this work."
"This side of you is how you got me like this.." You brush your thumb on his cheek. Somehow hearing this from him alone is enough to help ease your worry.
"Ahhh~ So you do like this side of me?" His voice drops to a teasing whisper.
"I wonder… was it the gentle touches? The sweet words? Or just how very persuasive I can be when I want something~?"
"Oh, you're definitely persuasive." You sweetly giggle, moving your hands to wrap around his neck.
"Somehow you're just so sweet on me when I'm nothing special.."
"Not special, you say?" He raises his eyebrow.
"Sweetheart… you're carrying the child of a demon, in a secret relationship with an upper moon that should be your sworn enemy… that doesn't sound very 'nothing special' to me."
You scoff with another soft chuckle. When emotions are foreign to you and something you're learning you would say something like that.
"Yeah? You think this is special?"
"Oh, I definitely do~ After all… how many demons can say they've managed to convince a lovely demon slayer like you to let them knock them up?"
"That lovely slayer almost sounding like a fool" You banter back playfully.
He teasingly taps your nose with his finger.
"Almost? My, my… you're quite the playful one today~ And I'm liking this side of you," Douma softly laughs.
"It's almost as charming as you were on our very first night together~"
"If you recall losing a hand charming that is," you banter still.
He chuckles at the memory, a sly smile on his face.
"A minor price to pay for getting the chance to touch you like this, I'd say~" He brings his hand up to your face, gently traces along your bottom lip with his thumb.
"And you weren't exactly complaining later, as I recall~"
"Persuasive.." You confirm and kiss his thumb before gently nipping it.
Douma's breath hitches. The kanji in his eyes flash with sudden intensity. He tilts his head down so that your noses brush together.
"Ohhhh?~ And what exactly am I being persuasive about now, darling? Should I stop?" His voice lowers as frost begins curling at the edges of your sleeves.
"…Or do you want me to keep going~?"
"Since I'm not trying to get you killed tonight, this estate is the last place you should be lingering around. So sadly, should probably stop.."
Douma's expression changes between playful disappointment and reluctant understanding, his lips lingering against yours for a moment longer before pulling away with an exaggerated sigh.
"Ughhh~ Always so responsible…" He flicks your forehead lightly, though there's no real annoyance in the gesture.
Rubbing your forehead you give him a look.
"Now whos being playful."
His hands finally release you as he steps back, but not without one last teasing whisper.
"Though I could just… sneak into your room later. If you get lonely~?"
"You're willing to take that risk?" You fold your arms in front of you.
"Who, me~?" He feigns innocence, raising a hand to his cold chest in mock surprise.
"Darling, I'm a master of stealth. I could sneak in and out of that adorable little room of yours without anyone even knowing. And I can be very quiet when I want to~"
You begin walking to the front entrance again.
Watching you walk away Douma's eyes have mischief in them once more. He presses the back of his hand to his lips dramatically. His voice in a songsong whisper behind you.
"Ohhhh~ Is that a challenge, Y/N? Should I test just how quiet I can be? Maybe… maybe if my little slayer leaves her window unlocked…"
You disappear behind the fence with a smile. The flurry of frost that was dancing at your feet where you had been standing already gone.
Later that evening, close to early morning, Douma kept his little promise, and easily slips through the open window to your room silently.
"Darling. Are you still awake?" He whispers the greeting into the quiet room.
His smirks softens taing in the sight of you sound asleep and unguarded. The exhaustion from the mission and being pregnant at the same time must've really taken you out.
"Already asleep?" He murmurs in quiet amusement, kneeling beside your futon. He reaches out to brush a stray lock of hair from your face.
"…Such an irresistible little slayer… I'll come by tomorrow instead.."
Your hand reaches out for him before he could pull away and stand as you start to slowly wake. You're still a slayer after all. You practically learned how to sleep with one eye open, just this pregnancy really takes that much of a toll on you.
"..stay.." You sleepily murmur, barely audible.
Douma freezes for a moment then slowly exhales.
"Sweetheart.." He carefully slips under the covers beside you and pulls you close up to him. This is srangely comforting to him in a way he's never felt before.
The room is silent. He's taking in the feeling of you against him, tracing idle patterns against your back.
"So foolish for letting me stay like this.."
"..maybe.." You murmur, opening your eyes and look at him in the darkness. Pushing back the wave of nausea that hits your gut.
".. you know I was half joking about you sneaking in, right.. like seriously.. what if you're caught."
Your discomfort didn't go unnoticed by him. He studies you.
"Are you feeling alright? And don't worry about being caught~ I've eaten far more dangerous things than a few butterflies." His light teasing returned.
"Very funny.." You dont hide how unamused you were.
"I would be torn having to pick a side.. and yes, I'm aright. Just nauseous."
Douma watches you more carefully and concerned, bringing his hand to your cheek.
"…When did the nausea start? And you haven't thrown up, have you?" He murmurs.
"It started a few weeks ago.. only sometimes.." You lean into his touch. Since he can only come out at night and not be around so often from our predicament he wouldn't have known.
"A few weeks?" He whispers, his voice sharpening with an edge.
"Darling… why didn't you say anything?"
An uneasy feeling curls in the pit of his stomach. To him this isn't normal. He tries to keep his voice steady for your sake.
"…Have you been… feeling any other unusual symptoms?"
"It's alright, really. It just comes with pregnancy." You try to reassure him.
"Just more tired as I've said along with some mood swings.."
His expression hardens that you could brush off your symptoms so casually. His stomach twists more.
"Darling… being this tired, feeling sick this often… That's not 'alright.' You should've told me—" He cuts himself off, running a frustrated hand through his hair to keep his temper in check before continuing in a quieter tone.
"You really are stubborn, sometimes, you know that?"
"Not exactly on my mind with such little time I get with you.." You close your eyes, more focused on relishing in the feel of his soothing touch right now.
You understand that he is just a man still after all. A man who has never experienced this before at that. He would overreact this way and that's okay.
"I suppose I can't argue with that." Your admission melts his frustration. He trails his fingers down to gently brush over the curve of your stomach where he presses another icy kiss, this one lingering just above the fabric of your yukata.
"It's not fault you're not familiar with the normal side effects that come with pregnancy.. Just.. why worry you with something so normal and have it take away this time.." You gently run your fingers through his silky hair in this tender moment with him.
Douma's shoulders relax, a low sigh escapes him.
"…Hah. 'Normal,' she says… Darling… nothing about being pregnant with a demon's child is normal~" he murmurs, presses another cold kiss just below your belly button.
"I'm going to worry anyway."
You quietly chuckle for getting checked, gently giving his hair a little tug.
"Alright, fine. You're right and got me there again.. demon pregnancy or human.. it's still pretty much all the same.."
"Ah… so you can admit when you're wrong~ I was starting to wonder…" He muses with a playful smirk, looking up at you to meet your gaze.
"Very funny," you softly laugh again and move your arms out of the way and rest them by your head on the pillow.
One of his hands slip under the your yukata to rest right over your stomach.
"Damn… you're beautiful like this."
He moves back up to captur your mouth in a deep intense kiss, savoring the feel of your lips against his.
"That.. is a very firm fact," he murmurs a low promise against your mouth.
"..and.. you are good a keeping your promises." Your stomach flutters. Not sure if it's butterflies he's giving you or if its the baby moving, maybe both. You bring your arms back to gently wrap around his shoulders, kissing him again full of affection.
Douma responds with passion, his heart rate spiking in his chest as fingers trail down your back to your waist, and pull you gently into his lap deepening the kiss.
"Mm.. I've always.. kept them for you."
Your leg instinctive goes over his hip, softly moaning in the kiss.
"Mmh~ Only you.. No one else gets to see me like this." He nips at your lower lip again before soothing it with his tongue. Moving his hand down to your thigh, slipping you yukata up slowly.
"…You're wearing too many clothes."
"Should probably fix that then.." You murmur, roaming your hands down his back.
He brushes his lips against your ear with growl.
"Careful what you wish for~" He slides the yukata down one shoulder with a yank exposing your breast to the cold air.
"Careful left the building a long time ago."
His breath hitches at the sight of you. He smirks dangerously.
"Ohhh~?" he drags an icy finger over your hardened nipple, watching your reaction closely. The way your chest rises to his touch with a gasp.
"…You're right. I suppose it did."
With a sharp flick of his wrist he tears the rest of your yukata open. Filling the room with the sound of it shredding. He's enjoying the view of you and how you're trying to stay quiet, purposefully leans down to nip your collarbone to try to get a reaction out of you.
"You know you're doing this on purpose.." You pant, moving your hands down to the bottom hem of his shirt, sliding it up his back slowly.
Douma chuckles, the feel of your fingers running over every muscle draws a shaky breath from him.
"Me? On purpose?" He murmurs against your neck, his lips tracing a slow path up towards your ear, and bites down lightly.
"…Darling, I am the picture of innocence~"
You graze your nails up his back, sliding his shirt up higher as a shiver runs through you.
"You're such a damn liar."
"Mmh~ And yet…" He nips at your earlobe, one hand sliding down to grip the inside of your thigh.
"…you're still pressed against me like you can't get close enough. Liar yourself, aren't you?"
"What." You pull his shirt off him and drop it on the floor.
"You think that after you impregnated, I wasn't gonna let you touch me anymore?"
He sharply inhales. The sudden press of your bare body against his sends a hot and electric jolt through him beneath the cold.
"Tch~ You were going to let me do this? Even knowing I could tear you apart with just one wrong move?"
His hips roll against yours deliberately slow and taunting to make you feel every hard inch through his pants.
"Even now? Yes.. I know you won't hurt me.." You quietly moan, pulling him closer to you.
Douma's breath hitches again at the sound of your shaky moan, the heat in you making his own temperature spike in an unfamiliar yet intoxicating way. He grinds his hips again in a slow deliberate roll. He shudders.
"You're… insane." He chuckles in your ear, murmuring huskily and breathless.
"Trusting a monster like me this much… it's not a smart decision, darling~"
With each roll puncturing a soft moan out of you, you grip the waistband of his pants, sliding your thumbs underneath the fabric.
"And you're just as insane for sneaking in here when there's other slayers nearby."
"Mmh~ You think I care?" He growls against your throat before nipping.
"I'd tear through every last one in this estate if it meant getting to do this with you. Now stop talking and let me ruin you properly~"
You pulls away for a moment to unbuckles his belt, the sound of the metal clining in the quiet room before he slips his pants off and tosses them aside with no care where they land. He slowly lowers himself back down over you, pressing feverish kisses along your jawline as he slowly grinds along your wet folds, lining up.
Your knees instinctively go up to his waist again in a press as you quietly moan, rolling your head back.
"We should hurry though.. don't know how much time we have left.."
"Mmh.. that's true~" he murmurs against your neck with desperation, gripping your hip tighter as he pushes just the tip inside. The tight feel of you is already maddening and yet he holds still.
"Nhh- haa.. but.. not too fast.." You grip his shoulders.
"Mmh~? Not too fast?" He purrs in mock concern before nipping your skin again.
"But darling… if I go slow…" He slowly pushes in a couple more inches, forcing himself to still again.
"…you might start to beg~"
"aahh.. you know wat I mean.. dont want to rush too much.." One hand moves to the back of his head, pushing your fingers through his hair.
"Mmh~ Tch—" He nips at your earlobe.
"You're… impossibly tight when I go slow like this… But fine. Since my little slayer asked so nicely~"
He pushes all the way in one slow, deliberate thrust causing you to moan out louder than you should've. The feel of you molding around him even tighter now than before from the anatomy change Douma bites down hard on your neck, muffling the guttural groan from his throat. He near digs his claws into your skin as he struggles to focus.
"Douma-" You hold on to him like a lifeline as a way to push back wanting to scream, the pain and pleasure shooting through you like ectasy. You try to steady your breathing.
"d-dont.. be so rough with me.."
Douma huffs at your words, pulling back from your neck relunctantly to look into your eyes. The sight of you beneath him is almost too much to take.
"Hahhh.." He closes his eyes, fighting the urge to just ravish you. Inhale. Exhale. When he opens his eyes again they're a little less feral.
"Mmh… but you like it when I'm rough~"
"Well yes.. but for now.. you know it's best were more gentle.." Youre already a mess, straining to keep your lidded eyes up on him.
His eyes flutter at the the idea of being slow and gentle with you. Its almost torturous after the taste of you while deeply connected like this, but he swallows it for now, he traces the side of your face in a gentle, shaky touch.
"Mmh… okay. I'll be gentle. For your sake." He murmurs, leaning down to press a tender kiss to your forehead.
"Let me know if it's too much, alright?"
You close your eyes for a moment relishing in the feel of his lips on you.
Douma exhales softly through his nose, pressing another slow kiss to your forehead then the tip of your nose before finally resting his lips against yours in a quiet, lingering one. He carefully holds on to your side as he begins moving with short, slow thrusts, staying deeply in.
"Mmh~… good." He murmurs between kisses.
"Because I'm not done with you yet…"
"I'm not gonna last like this.. you feel too damn good-" Your lips part against his, softly moaning.
"Tch, I'm… not… either…" He pants quietly, his words broken up with low groans as he leans in to nuzzle his face against your throat. A shudder rakes through him. Douma's barely holding himself back from going too fast and hurting you right now. Your voice, your heat, the way you feel beneath him is making it a hell of a struggle.
You bite down on your lip once more to silence yourself, arching your hips to change the angle.
"Ohh- just like this.. right there-"
Douma's control nearly almost slips again,pressing a hot open-mouthed kiss to your neck, one hand sliding down to your lower back for a better grip.
"Mmh, don't bite down too hard… or I really will go rough~" He murmurs in warning.
"J-Just don't stop- ohh fuck.. don't stop-" Each deliberate thrust bullies your core to peel back like flower petals and open to him for his taking. The coil in your stomach is aslmost unbearable, your so close to tipping over the edge.
The sound of your moan makes his entire body shudder, his grip on you becomes a little desperate. It takes all he has to keep his thrusts slow and careful, his teeth grit tightly as he hisses against your skin.
"Ttch- I won't, I won't." He kisses you hard, his teeth nip at your lip.
"Not until you're full of me… Mmnnh, not until you're completely mine."
Unable to hold on any longer you snap hot and sharp, ripping through you like a waves that hits too fast.
"Douma! I'm-" You sob into his mouth with your voice cracked, clenching around him tightly as your orgasm slams into you.
He grips the sheets to keep himself from losing it and going too hard, his other hand cradles your head as he pants in between, kisses you frantically.
"Mmnnh, say my… nnghh- my… name like that… again. Please."
Lost in the sensation of him you moan out pathetically, obeying.
God, that's it. The way you gasp and moan his name like that just makes him insane with desire. He almost can't think straight.
"Mmnngh- ah, ah… say it again, please…" His body has been coiled so tight and tense for so long that it takes everything, every ounce of restraint, to prevent himself from snapping and just slamming into you.
"I can't hold out much longer, love. I need you…."
"I'm yours. Cum baby- yours."
That. Those little words break the last sliver of his remaining restraint. With a choked gasp, he crushes his mouth against yours in a hard, desperate kiss, his body shudders violently as he finally tips over the edge.
"Douma-" You moan out broken one final time taking every drop of his seed he has to give you with each rope.
A strangled gasp escapes him and he buries his face in the crook of your neck, shuddering in the aftermath.
"Haaaa…haaaaa…." He pants against your skin weak and shaking, his grip on you still tight even in the midst of ecstasy.
"You did so good.. so amazing.." You hold on to him close to you unmoving and spent. Softly kissing his head.
He chuckles, after a moment lifts his head up to look down at you. Despite the haze of the aftermath still lingering, he manages to give you a smug, satisfied smile.
"Mmh… I think the word you're looking for is 'godly'," he corrects you with a light tease, gently tracing his thumb over your lips.
"And I'm flattered you think so, darling… but you're the real sight here right now. All flushed and breathless, and mine through and through~"
"You're quite the sight yourself my guru, getting taken out by a human like me.." You tease back, softly kissing his thumb.
His heart skips a beat and chuckles again.
You soften even more looking into his eyes, your hands roaming his back.
"You think the little one is okay in there after that?"
With a grin he moves his hand from your mouth to your stomach, the gesture almost worshipful.
"Oh, the little one is just fine~ You don't need to worry about a thing." He murmurs, gently kissing your forehead before slowly pullin out of you with a hiss.
"Nhh- I'm glad you think so.." You grunt with a whine from the pull and sudden emptiness.
"And.. didn't have to right away.."
The sight of you is almost too much to handle. He wants to just push back inside you, claim you again and again until you're thoroughly marked by him and him alone, but he manages to hold back just in time with a sigh lowering his head on your shoulder, distracting himself with rubbing your stomach. He exhales deeply.
"You know exactly what you're doing right now, don't you..?"
You hold him even closer if that were possible.
"I'm sorry. Didn't mean for that to be teasing. I just.. don't know when I can see you again, so didn't mind staying connected just a little longer" Another soft kiss to his head.
"I… get it. Believe me, I do. I…. I don't want to let go of you either.." He breathes out that confession quietly with a hint of vulnerability. His demon heart aches at the thought of parting ways again, inhaling your scent deeply as he wraps his arms around you tightly.
"You feel the same..?" You nuzzle into him.
Fuuuck, that tone in your voice is like a dagger in the heart and makes his arms tighten even more around you.
"Mmh, more strongly than you can imagine, love." He murmurs back, pressing a row of soft kisses along your neck, his hands tracing lazy patterns across the skin of your back.
You softly giggle trying to brighten the mood again.
"Keep talking like that and you'll sound like a lovesick pup."
Douma's breath hitches, loosening his hold on you just enough for him to pull back and stare down at you with a look of mock offense. The slight flush on his cheeks betrays him.
"Mmh? A lovesick pup?" He leans in closer, nipping your earlobe playfully before murmuring.
"…Careful. You keep teasing me like this and I might have to prove exactly how much of a 'pup' I can be~" A slow smirk spreads across his lips as he drags an icy finger up your spine.
You giggle again at the chill thats refreshing against your hot skin then turn your head towards the shoji hearing movement among the mansion, and then to the window to see the sky has changed a shade of dark blue. The mansion is starting to wake and start the day. You look at him again.
The light mood faded as quickly as it came. He cups your face gently as his eyes trace over every contour on your face.
"I… yeah. I know. I just need… one more minute.." He whispers back softly and leans down to kiss you again long and slow.
You lips linger on his before reluctantly pulling away.
He wants nothing more than to stay here with you, forget about everything else, and just… But he doesn't. Instead, he nods in agreement, tenderly presses a final kiss to your forehead before untangling himself from you.
"…I'll come back. Just… wait for me, alright?"
"I will.." You sit up watching him quickly get dressed and take his leave.
"…Good." His voice is quiet but firm. "Because I'm never losing you."
Douma pauses at the window and glances back one last time at you. Then in the blink of an eye at demon speed, he's gone.
Alone in the room the tears you held back go down your face already missing him and feeling alone. Damn pregnancy hormones.
