sub!Diluc x Dom! gn! reader
Warnings: very much not safe for w, edging, overstimulation, praise kink, minors get out of here. But also, some unabashed fluff. Yes, it contains multitudes.
words: 3,2k.
A\n: This somehow turned into Diluc character study, but I promise I will get to the filth after the psychological profiling. also, I know I tend to write in an authoritative voice like I'm stating facts, but these are just my personal opinions and if you interpret characters differently, more power to you.
Listen, i know everyone hcs Diluc as a dom. And he can be a very nice service dom, but I’m here to convince you that sub!Diluc is actually not OOC.
First of all, he’s more repressed than a catholic nun. Diluc is like on six levels of dissociation at any given moment. He sees his body as a flesh suit he’s piloting that requires an inconvenient maintenance like sleep, food and occasional sexual release. He’ll jerk off by himself like it’s a chore. 
Diluc is so touch starved it’s ridiculous, and *he doesn’t even know it*, that’s how much he’s disconnected from his needs.
And like. Helping ppl like that discover what they actually want and watching them come undone in pleasure they didn’t know they desired is so delicious. If you know, you know, there’s nothing quite like it.
But you have to go slow with him
I mean first of all, you shouldn’t mess with Diluc at all if you’re not in for a long haul, this man doesn’t do casual.
Oh, he’ll agree to try if he’s already into you, he’s incredibly indulging to the people he values. But also because at first he’ll be incredibly defensive.
Not because he’s not into it. Just as a defense mechanism, as he thinks he’ll disappoint you and he’s preparing for a failure from the start.
Diluc can see any activity with his important people as a trial where his performance will be evaluated. He is one of these “I need to get a good grade in X which is both normal to want and possible to achieve” people.
Remember the coffeeshop event where he was like “When I was a small child, my father told me to mix my first drink using all of the ingredients in the tavern. In hindsight, it was probably to see how creative I am and I must’ve failed because I just made a fruit punch and my father didn’t say if I did well”?
Like, Diluc. Baby. Honey. Sweetie. Your dad probably just wanted you to have fun in an improvised “take your kid to work” event. He didn’t judge your punch because it was about spending quality time together and letting you play with colorful syrups. Who the fuck would evaluate a small child’s creativity on the first time they mix drinks. You think he expected you to invent Pina Colada?
So yeah, he will see even getting edged as a thing he’s not proficient in, so he’s most likely to fail and disappoint you. And that’s one of the worst things he can imagine.
Because being useful is Diluc’s love language. If you read his voicelines or talk to him in teapot, you can notice how he’s very focused on doing things for you, like he’ll invent a drink specifically for you and keeps repeating that you should tell him if you need anything, but at the same time, he “doesn’t do chit chat” and wants to leave if there’s nothing for him to do. 
Because Diluc knows he’s not easygoing or fun to be around. He has his charming brother who makes it seem effortless to compare himself with. He knows he’s kind of awkward, intense, brooding and direct to the point of coming off as rude. So he needs to feel like he’s doing something useful for you to justify spending time with you. 
So for his first time, don’t tease him verbally. He’s incredibly teasable, I know. But he’s already very anxious about disappointing you even if he tries to hide it and he was conditioned to clamp up at the first sign of perceived mockery by his troll brother. Show him first how good it can feel before you start playing with him.
also, he obviously has a praise kink that he’s not even aware of. like, it’s not even up for discussion, praise from other people and approval from his dad are literally described as his main motivations
“The praise he received from his comrades and citizens spurred him on. But the words of praise he valued most of all were: "Good job. Now, that's my son." His father's words fueled the fire inside his heart and served as his greatest motivation.“ and sure, after he lost his dad and emotionally closed off, he doesn’t allow himself to rely on approval of others. But it doesn’t mean he doesn’t want it. 
You can tie his hands, but honestly I think it’s much more fun to just order him to keep his hands up. He’s so stubborn, it’ll be a matter of pride for him to keep his composure. And it will also make it that much more delicious to see it finally break.
When you tell him that he must ask for permission to finish, he just scoffs. He’s so sure he wouldn’t be reduced to that.
Don’t expect him to dissolve into stereotypical meowling and begging when you first start touching him. Again, he’s much too stubborn. He’s coming into this defensive and he wants to be in control of himself. 
But hear me out - it actually makes it more fun to tease him. Diluc tries to keep himself still, but no amount of willpower will make him less sensitive and, again, touch starved to hell and back. 
So at first, it’s the little things that betray him. How when you kiss his neck, his throat moves under your lips in a shaky intake of a breath, How the taut muscles of his scarred arms flex when you run your hands over his chest. How he draws in his stomach when you slide your fingers down it, slow, tantalizingly slow, making light patterns with just your fingertips. How he avoids your eyes because you haven’t even touched his cock yet and he’s already so obviously, painfully hard.
He has a beautiful cock, big and with a nice curve, and as for all pale redheads, it becomes brilliantly red when aroused. When you finally touch him, slowly stroking it up from the base to the tip, he draws in a breath through the clenched teeth and squeezes his eyes shut. You watch him struggle as you start pumping his dick faster and faster, his jaw clenching, his breath and heartbeat quickening, sweat beads forming on his forehead, his shoulders and hips flinching as he tries to keep himself from arching up and thrusting into your hand. 
He’s fighting a losing battle and both of you know it by now. You could break him right here if you wanted. You squeeze and rub the sensitive tip of his cock, and see him open his mouth in a silent, chocked gasp for air. He manages to keep himself from clenching his fists, but his knuckles whiten when he desperately scraps his fingertips against the bedsheets. 
But you don’t want him to feel like he lost a fight, it’s not about that, it was never about that. Even shame should feel good. You caress his high, sculpted cheekbones with your thumb, your other hand still on his cock. “‘Luc, look at me.”
He can’t disobey you, but he has to take a deep breath before he can open his eyes. He meets your gaze, anxious. What’s he going to see, mockery over how pathetically quick he’s breaking down? Disappointment for how bad and inexperienced he is at this? Just a cold, severe rejection?
“You look so beautiful, baby,” you tell him quietly and breath catches in his throat, his pupils widening, his cock twitching in your hand. You kiss the trail from his sharp jawline up to his ear, allowing him to turn away. “Do you enjoy this? Do you want me to keep going?" you smile warmly when he whips his head back to look at you and meet his dazed crimson eyes. “I just want you to feel good.”
This reframes the entire scene for him in a one fell swoop, turning it upside down, leaving him disoriented. It wasn’t a challenge that he was losing, or a trial that he was failing, him giving in to his desires was what you wanted all along? You enjoy seeing his pleasure, even if he’s not being useful to you in return? It seems impossible to him, yet when you look at him like this, when you touch him like this, like he’s precious and wanted, when he knows he’s broken and undeserving… it feels intoxicating and liberating at once, in a way he couldn’t imagine before. He realizes at this moment how badly he wants this, even if he still doesn’t understand how far he’s willing to go for it.
“I… ugh, I… like it,” Diluc swallows harshly, his mouth suddenly dry, and if you thought he was blushing before, now the pink dust on his cheeks turns into a brilliant scarlet glow, covering his face, neck and even top of his shoulders. He clearly wants to look away in embarrassment, but makes himself hold your gaze. “If you… enjoy this too and… want to go on…”
You rake your eyes over him, sprawled in front of you, and smile, meeting his gaze again. “Of course I enjoy it. You look so fucking hot like this.” his eyes widen and his lips part, you can feel his tip leaking in your hand, his entire body strung up like a bowstring. He doesn’t know what to answer and he couldn’t talk even if he did, so when you lower your head down to kiss him he answers eagerly, with passion and gratitude he can’t express in words. You start pumping his cock again, now faster and with a firmer grip, and drink in his abrupt gasp against your mouth, as he freezes for a second and then returns the kiss with twice the abandon. This time he doesn’t try to fight it, his body trembling under you, his hips bucking up to meet your hand, his hands closing into fists, toes curling. 
He breaks the kiss when you twist your palm against his pulsing tip, and he cries out, low and strangled, his entire body arching up, but his unfocused eyes find yours immediately, his gaze frantic, almost feverish. He’s going far outside his comfort zone, he’s relinquishing control and he’s so unused to this, he trained himself for years to do the opposite of this, to see it as a failure, so he needs your repeated reassurance to soothe his anxiety, to prove he didn’t imagine your desire few moments ago.
You lean down to him without breaking eye contact. “You’re doing so good, baby. You’re being so good for me.”
It shoots through him, bypassing the brain entirely, through the entire nerve system and right down to the cock, like only discovering a kink you were entirely oblivious to before can. His body goes rigid and he comes, with a choked, shuddering groan. 
You stroke him through it, until he limply falls back on the bed, spent and panting. He reaches for you and you let him pull you in, hold him while he’s coming back to his senses, run fingers through his soft hair. When he opens his eyes, he looks at you with a small, almost sheepish smile, and it’s impossible to resist kissing him.
“Are you okay?” you ask, stroking his cheek and he leans into your palm.
“Yes, I’m fine,” he answers immediately, then realizes how it sounds and tries to correct. “I mean, I’m better than fine. I’m... I feel good.”
You chuckle and his eyes flicker to watch your mouth, then throw you a glance from under half-lowered lids. It’s enjoyable seeing him open like this, but what you really want is seeing him come undone. He doesn’t look tired and you know he can go on for much longer, but today it’s more a question of mental state than stamina. 
“You want to go for another round?” you ask softly him and he blushes lightly.
“Well, I did technically… um, break a promise to ask for permission in the end,” he says with the same small smile that grows even more sheepish as he tries to avoid admitting he desperately wants more. “So it’s only fair if I remedy that.”
“Oh, of course. Honorable as always. So noble of you, Master Diluc,” you run your fingers over his abs, spreading cum all over them, and his brilliant blush returns in full force. But he doesn’t stop smiling, trusting your good intentions, that you’re mocking the hierarchy of ranks and not him personally. You kiss the corner of his mouth to reassure him, and his smile grows wider.
“Well, you can’t be successful in the commercial trade if you’re not answering for your obligations,” he says, trying and failing to keep a straight face. He really does recover very quickly, you think, if he can already banter. “The Wine Guild would kick me out if they learned I’d backed down on a deal.”
“Well, at least I know I can complain to the Wine Guild if you misbehave then,” your voice is still light, but you catch his chin and lift it up firmly, and he tenses up immediately. 
He looks up at you, eyes intense as always, but now glittering in anticipation and tracking your every move, bangs tousled and lips parted for you to claim. You kiss him, messily, greedily, slide your fingers to the back of his head and pull on his hair, forcing him to expose his throat for you. You leave the trail of sloppy kisses and scraped teeth down from his jaw to the collarbones before you let go of his hair and allow him to collapse. 
When your hand finds his cock, it’s already half-hard, throbbing. red. This time, you don’t go slowly, you grab it and start pumping it fast. He shudders, still so sensitive after a recent orgasm, and instinctively tries to close his legs.
You don’t force them open, instead, you catch his chin and meet his eyes again. “No,” you say slowly. “Open up for me.” 
The thing about Diluc is that he doesn’t do anything by halves if he sets his mind to it. Once he opens up, he burns for you with the same single-minded dedication as he does fighting enemies in the night. He might not know how to ask for help, pleasure or affection, but he sure knows how to give and to give everything he’s got. Do not ask to have him if you want anything less than the whole.
He grits his teeth, his eyes smoldering crimson, and forces himself to spread his legs again, against his basic reflexes. The touch to his overstimulated dick is painful and igniting at the same time, it feels equal parts wrecking and delightful.
You smile and praise him and pump him even harder and faster than before, and he trashes in front of you, muttering a litany of half-choked curses, throwing his head from side to side, hands clawing at the sheets, thighs shaking, but staying open.
You asked for him and you shall have him, no matter what.
It’s still not enough for you, though.
You sprawl on your side against him, circling one arm around his shoulders, still stroking him with the other. The fight goes out of him. He blindly leans into you, trembling, a small whine caught in his throat. When you kiss him, his mouth is soft and pliant, but his hands clutch at you desperately, like a drowning man trying to hold on to the solid ground. 
It drives you crazy to watch him writhe under you, completely unravelled, glowing brightly from feverish desire, scarlet silk of his tangled hair sprawled on the sheets, his hips bucking frantically into your hand. 
You whisper sweet, tender praises to him, caress his face, neck and shoulders like he’s the most precious and fragile thing in the world, at the same time as your other hand relentlessly winds him up, squeezes his overstimulated, pulsing cock harshly, twists the leaking tip. The pain punctuates desire, a delirious contrast of torturously sweet and deliciously cruel.
His fingers dig into you, holding you close. He presses his face into the crook of your neck, clings to you, seeking comfort and shelter from the same sweet, unbearable torture that is also inflicted by you. The pleasure melts him, but the pain splits him open, wrecks him to the core, he wants this to end, and he wants this to never stop. More than anything, he wants to be yours.
“Fuck, look at you. You’re perfect,” you tell him and you mean it.
He breathes in through his mouth, drawing in your scent. “Please,” he gasps so quietly, you could’ve missed it if not for his lips moving against your neck. “Please, let me…please…”
Next time, you might demand more. Next time, you might make him spell it out completely, what exactly he begs you for. But this is his first time and he was already so brave for you.
“Yes, baby. You’ve been so fucking good. Come for me.”
He comes immediately and so hard, his entire body is shaking, the strangled scream caught in his throat. You keep stroking him, letting him ride it out through increasingly frantic and desperate thrusts, squeeze every last drop out of him until he collapses, limp and shivering, but still clinging to you.
You hold him, stroke his hair and kiss his forehead, whisper to him softly until he stops trembling and his breath evens out. You realize that he’s too weak now to get to the bath, so you stand up to get something to help, but he reaches out, catches your wrist immediately.
“It’s okay, I’ll be back in a second,” you promise. After you clean him up with a wet cloth, he pulls you in and curls around you so possessively and needy, you can’t help but smile. He’s fighting a losing battle to stay awake, the endless sleepless nights finally catching up with him, now that he lowered his guard for a moment and let his body feel alive. But there’s one thing he needs to ask, suddenly apprehensive now that the rush of lust passed.
“Did you… Was I… Ugh, damn. Would you perhaps?..” he stumbles over his words, not knowing how to phrase his concern that he wasn’t good enough for you and you just indulged him. You stop him mercifully.
“I *did* enjoy it. You *were* incredible. And yes, I would very much love to do this again.”
“Oh,” he says, relaxing against you, the same precious small smile appearing on his face again, now more content than sheepish. You chuckle, stroking his face. 
“Besides, you did break my order to keep your hands up. You’ll have to suffer the punishment, or the Wine Guild will need to hear about this.”
He snorts indignantly and blushes at the same time. For the first time in many, many nights he falls asleep with a light heart and a smile still tugging at his lips.
a\n: I had fun writing this, so I might make this into sub!character series. Not taking specific requests per se, but you can let me know which adult genshin characters you’d be interested to hear my take on, both male and female.
