#luckae Dark noble AU/ where Kaeya was taken in to be a playmate for Diluc, but eventually a servant. Diluc and Kaeya still grow up to have somewhat of a fall out but Diluc does not leave, and instead is pressured into an arranged marriage with another noble woman 1/

Diluc is unhappy with it but tolerates it because thats life, so while he's not very affectionate with his wife and is a little cold, he's not openly cruel, especially in public.

One night, when a ball is being held at Dawn Winery Manor, Diluc is forced to 2/

make boring, stuffy conversation with other nobles for the whole night after a long day of work. He's worn out and at the end of his patience. He holds it in until a foolish noble makes a rude comment about Diluc's late father, and Diluc's temper flares. 3/

He's about mere seconds away from knocking the snivelling fool on his ass, but a tactful butler Kaeya sweeps in and manages to intercede. With an offer of refreshments here, and some sweet words there, he is able to diffuse the situation before Diluc does something 4/

that would damage his reputation. Still, even as Kaeya leaves and the conversation changes back to boring pleasantries, Diluc's fury has not been cooled, just temporarily blocked. Diluc excuses himself to retire to his office for awhile to address some pressing 5/

paperwork (and get away from these jabbering idiots). He orders Kaeya to tend to him as he walks past, not even looking at him. Kaeya politely finishes his conversation and dutifully follows his master out and to his office and the back of the manor. 6/

This wing of the manor is pretty much deserted because of the party so the two walk silently without interruption.
When they get in, Diluc orders Kaeya not to lock the door behind him. Diluc then leans against the front of his desk and takes off his gloves 7/

and watches Kaeya with a burning hunger and a predatory glint in his eyes.
Kaeya can't help but feel like those eyes could eat him whole with their gaze alone.
"Undress." Diluc orders. Kaeya hesitates after taking off his coat. Diluc's fierce gazes bores into him. 8/

"Were you drinking on the job again Kaeya, or shall I repeat myself?" His eyes narrowed as he crossed his arms. "Now." his voice grew sharp.
Kaeya resumed, burying his feelings beneath his cool exterior. He undressed himself, arriving at his under garments. 9/

They were expensive and detailed black lace, fitting him perfectly and accentuating his narrow waist. The lace around his chest was snug, squeezing his tits so his nipples stood out.
But Diluc didn't even blink at the sight of it. 10/

Afterall, he was the one who had them custom designed and paid for. Any servants who had caught some small wind of it, assumed the master had to have commissioned such a naughty set for his wife, but his wife didn't even know it existed. It was custom made for Kaeya alone. 11/

Diluc held his hand up for Kaeya to stop before he took the lingerie off.
"Leave it on."
Kaeya's fists tightened and a blush snuck past his resolute cool facade.
Diluc gestured Kaeya toward him. Kaeya strode over to his master, as quiet and elegantly as a cat. 12/

Diluc embraced Kaeya, instantly laying one harsh and possessive grip on his waist, and the other on Kaeya's perk ass, giving it a squeeze. Kaeya bit his lip to stop the gasp. Diluc never took off his gloves, even for his wife. He said it was because 13/

he occasionally had trouble controlling his pyro kinesis and did not want to accidentally hurt his delicate wife, and it was partly true as Diluc could lightly burn with his touch alone, but he had no qualms about laying his bare hands upon Kaeya. 14/

It would be accurate to say Kaeya is the only one who ever felt Diluc's bare touch, it was a feeling reserved only for him. Diluc's hand were hot and Kaeya could feel the light burn as he embraced Kaeya's skin, sighing at the cool feeling of Kaeya. 15/

Diluc seemed in no mood to be gentle or beat around the bush, practically lifting Kaeya up and almost throwing him down across his desk, scattering some of the piles of papers on it. He began to unbuckle his belt before Kaeya's façade finally crumbled and he reached out to 16/

stop Diluc, panic colouring his voice. "Wait- the door, its- its not locked." Kaeya's eyes darted to door, overly conscious of the lock not being in place. Even if this wing of the was deserted, anybody could walk past... 17/

A smirk danced across the handsome lord's face. He gazed down upon the pretty blue haired man beneath him, adorned in lingerie Diluc had picked out specifically for him, that he had been wearing all night as he had commanded.
"Good."
18/

Diluc wasted no time in railing his pretty little thing, moving Kaeya's lingerie to the side and not bothering to even remove it, driving his cock into Kaeya's tight heat. He drunk up his moans and delicate mewls as he hit him too hard and too fast, 19/

using him the same way one would a prostitute for a quick and dirty fuck.
He made sure to pound into hard enough the desk shook and papers and other stationary on the desk fell to the ground. The papers crumbled under their moving bodies and spots appeared where 20/

there sweat had dripped onto it. He didn't care for the mess he made, of the desk or Kaeya, Kaeya would have to clean it up after. Maybe he'd make him do it straight after, before he'd given him permission to dress and he still had cum leaking out of him 21/

Diluc found himself enjoying the idea a little too much and decided that he'd do exactly that. Maybe after spanking him a little but after too, when he was still over sensitive from cumming. That way Diluc would have a nice pretty pink red ass to stare at as he watched 22/

Kaeya crawl on the floor to clean up, too tired to stand properly.
He pulled Kaeya's hair as he went faster, uncaring of the small pleas from Kaeya to slow down. Diluc only just noticed that Kaeya had come recently, still recovering from the high of that. 23/

He'd spilled all over himself, without Diluc even needing to touch him. Diluc couldn't even repress a satisfied and possessive growl at the sight of it. Kaeya was well trained, no matter how embarrassed he was about it. All he needed was his masters cock and he came undone. 24/

Diluc didn't need to be gentle or considerate with Kaeya like he had to be with his wife, he could be as rough as he wanted. Kaeya was his. His faithful servant during the day, and his dutiful slut during the night. 25/

Diluc made sure to fuck Kaeya in the spot he knew made him see stars, forcing that delicious voice of his out. He wanted anybody walking past to hear his Kaeya's lovely little singing.
He wanted them to quietly open the door an inch, see the sight before them. 26/

The noble Lord of House Ragnvindr, fucking someone who wasn't his wife, into his work desk. They wouldn't be able to see Kaeya's lewd debauched face from the angle, just his lithe legs and thighs tightened around Diluc wide 27/

and imposing back, trembling from each fierce thrust.
And if they noticed a darling baby born in the servant quarters nine months from now, with flaming red eyes or hair, they'd know to keep their mouths shut from one deathly glare from their lord. 28/

He fucked into Kaeya hard, cumming inside his tight wet heat and filling him to the brim with his hot thick cum, feeling it leak out the sides as he began to pull out. Kaeya was almost sobbing, trembling upon his desk, trying to regain any shred of his ripped apart composure 29/

Diluc gave a satisfied slap to his ass, earning himself a soft whine from below him.
Not forgetting his duties, Kaeya strung some words together, a little gravelly from moaning himself hoarse.
"T-Thank you my lord. I hope I was able to be of a-assistance, and relieve some of 30/

your stress." Kaeya's pretty little lips struggled out. Diluc thought about fucking his lovely little mouth too, but he had to return to the party soon, lest his wife send the whole party to find him. 31/

With a deep sigh, Diluc put himself back together and sat on his office couch, reclining into it.
"Clean the desk up first before yourself." He order Kaeya, watching the scene with a burning gaze. 32/

will continue soon, gotta have a shower first

sorry will have to complete tomorrow after work ; _ ; already 11:30pm and I gotta get up at 5:45am tomorrow rip. but I still have a couple ideas for this, so let me know if you'd like to hear the rest

Sorry for the delay! Im not used to 9 hour work days esp that early so it kind of just killed me for a few days. Thank you for everyone's understanding and kind words of support 😭 I probs would have given up on this otherwise
I will now continue the Dark Noble thread!

Kaeya, still panting slightly, lifted himself off the desk with what look liked a good deal of struggle. He couldn't stand properly, his legs wobbling like a fawn's. Instead, he used the desk to lower himself to the floor. It wasn't a very graceful 33/

or successful manoeuvre, more of a controlled fall to floor. He hissed in pain as his legs gave out and fell to his knees on the floor.
Any kinder person would have felt a pang of sympathy for the beautiful man. Diluc felt barely a flicker, enjoying the image 34/

of Kaeya kneeling on his floor, still in dishevelled expensive black lace, and Diluc's seed leaking out of his hole.
He watched as Kaeya practically crawled across the floor on his hands and knees to pick up the scattered paper and stationary Diluc had knocked off 35/

his desk while railing Kaeya against it. Kaeya didn't complain and stayed silent mostly, save for the occasional hiss of pain, or shiver from the sensation of Diluc's cum leaking out of him, that a lip bite couldn't suppress. Diluc could rest assured Kaeya would 36/

place all his things back neatly and like it had never been touched. He would place it all back in a perfect manor with no complaints while his lord behind him lounged.
A part of Diluc was satisfied, and even hungry at the sight. Kaeya's obedience was something Diluc was 37/

immensely proud of, but also deeply possessive of. No one else was allowed to see Kaeya in this state. No one else was allowed to take him by the hair and use him like a velvet fuck toy.
Kaeya was his. And he always had been, always will be. 38/

Still there was a small voice in Diluc that bucked at the thoughts. The small voice protested at his childhood friend's treatment. They berated Diluc's callousness and felt pity for Kaeya.
The indignant voice inside of Diluc told him to remember what he and Kaeya had promised 39/

to each other as children.
In the fields of the winery, while hiding from the watchful eyes of Adeline as she tried to call them back from their adventures in time for dinner, they held hands.
Diluc's sunny expression was a stark contrast to the severe poker-face he 40/

wore these days. The voice in him told him to recall the words.
"We'll be best friends even as adults." Diluc said confidently, like he had all the assurance in the world of an oracle. Kaeya's tone was unsure, but his lovely starry eyes twinkled in excitement. 41/

"Are we allowed to be friends? Even when we grow up?"
Diluc snorted. "Of course we can. Father says people have to listen to me because I'm a Ragnvindr. No one will be able to tell us off when we're older." He wrinkled his nose in distaste. "Even the stuffy officials in the 42/

noble circle."
"Do you promise that?" Kaeya asked, a little shy. Diluc took his friends hand in his and nodded enthusiastically.
"I promise it!" He said with all the solemnity an 8 year old can muster. "We'll be together even when we're older. I'll take care of you Kaeya." 43/

Kaeya's face lit up, and Diluc remembers thinking that his smile put the sun to shame and the flowers blush in embarrassment. There was no one as lovely as his friend Kaeya.

But adult life wasn't as easy and malleable as they had thought. 44/

Kaeya was never given a station of his known, instead pushed into a contract he had no real choice in as a butler.
Diluc's father was dead, probably by the orders of some the rival nobles he was forced to play nice with today. His childhood dreams and kindness crushed under 45/

weight of being shoved into a position given to him far too early, and one that he had to fight many years for control over.
And Diluc had a heavy ring on his finger that he despised.
Life wasn't sunshine and sweet promises like it was in his childhood. 46/

Diluc looked back at Kaeya as his mood soured from his own berating thoughts. He gazed at Kaeya's plump ass as it leaked cum down his smooth thigh.
He stood up and strode over to the desk, grabbing something from a locked drawer. Kaeya lifted his eyes up to Diluc, 47/

the midnight blue of them just obscured by his alluringly long lashes.
No good man should look as enticing as Kaeya. How could any man resist messing him up when he looked like that? 48/

Kaeya had no one to blame but himself, looking like a sin even a devoted man would throw away his faith for. Diluc walked over to Kaeya, using his ungloved hand to tilt Kaeya's chin to look back up to him. Diluc liked the position of it, having Kaeya look up at him, still
49/

looking debauched from what Diluc had done to him, and kneeling before him.
Kaeya held his gaze, only wavering to the object in Diluc's hand as he brought it up. The neutral mask Kaeya had adorned himself with again, once more began to tremble and cracks begin to form. 50/

In Diluc's hand he held a plug, stainless steel, but with a ruby encrusted on the outside.
Kaeya shivered at the sight, his fingers curling. Kaeya did not pull away but Diluc could see hesitation creep through his carefully held mask. 51/

Diluc said nothing, pulling Kaeya back up and into his arms, allowing Kaeya to lean his unsteady weight off his own feet and onto Diluc instead. He held him a moment, just long enough to feel Kaeya's breath steady. Then he ignored the peace it brought him to have 52/

his childhood friend his arms like this, and pushed Kaeya to the desk. He did not make Kaeya lay across it again and undo all the clean up Kaeya had done before, but instead held Kaeya's back to his chest as he allowed Kaeya to brace himself on the desk. 53/

Diluc wasted no idle time in preparing Kaeya, knowing the tight hole would be slick with his seed anyway, and pushed the plug in. Some of his cum leaked out from the sudden intrusion, but most was sealed in. Kaeya's back arched minutely, trying to hide the 54/

shiver that passed through at the feeling of Diluc's seed pressed in further inside him. Diluc admired the sight of Kaeya once more.
A sparkling Ruby now sat between the plump cheeks of Kaeya's ass.
Diluc leaned against Kaeya, caging him with his body, close enough that 55/

Kaeya could feel his warm breath at his ear.
"Keep it in all night."
Diluc punctuated it with a harsh slap to his ass. "That's an order."
Kaeya nodded. "Of course, my lord." 56/

Diluc lingered a moment, telling himself it was to relish the touch of Kaeya's soft skin against his body and the feeling of possessiveness it stoked within him. He pretended there wasn't a part of him savouring the warm facade of an embrace. He pulled away, restoring 57/

his own mask neutrality across his face. He retrieved his discarded gloves that Kaeya had neatly folded while tidying the desk. He didn't look at Kaeya as he strode to the door of the office, throwing a casual "return once you've finished." over his shoulder. 58/

Diluc returned to the mind numbingly boring party, but at least he wasn't on the cusp of strangling anyone as he had been before. Rather than irked and frustrated, Diluc was simply bored, his attention elsewhere, waiting for Kaeya to return to his peripheral vision. 59/

Eventually Kaeya did return, just long enough after Diluc that he seemed to have finished something up for him, instead of putting himself promptly back together after his lord fucked him into a hardwood desk. His appearance was more or less impeccable as usual, 60/

nothing out of place that even the servants would notice. Just as Kaeya hoped they wouldn't.
Diluc clutched his glass a little too tightly, before he reined himself in.
It was not like he wanted the whole of Monstadt's nobles to know he was keeping his childhood friend 61/

as a mistress. That would of course cause far too many headache inducing problems.
It was not worth it.
Diluc stared at the wine in his glass and let his mind wander, allowing the circle of nobles that flocked around him to chatter uselessly away. 62/

If Kaeya were capable of baring children, that plug in him would likely ensure he would get pregnant. Diluc fucked him so hard even a bull with an aphrodisiac in its system would be put to shame from his vigor. Diluc enjoyed the thought of having bred his lovely minx. 63/

It would naturally be a disaster. He'd have to send Kaeya away, his wife would likely give him an earful he couldn't shut down. She'd find out the hard way of what her husband does to the pretty servant he always keeps around him. What he does to those pretty little lips, 64/

how he squeezes that tiny waist, and how he marks those perfectly round cheeks by digging his nails in.
She'd have to look at the servant and face the nagging truth everybody who attends the house notices, that the servant is more beautiful than the wife. 65/

She'd be constantly reminded of where her husband's attention really is at when she sees an adorable little red head with eyes adorned with stars running around the manor.
It would never work. Diluc would have break off the loveless marriage and run off with Kaeya. 66/

They'd have to live together on much simpler and smaller resources. They'd have to hide and be content with just each other.
They'd no longer lord and servant, they'd be best friends like they had been as kids. 67/

He eyed Kaeya out of the corner of his eyes, serving drinks and chatting cordially with the nobles as he walked around.

Neither of them would have to wear masks. They could drop it & smile honestly as they had as kids.
It'd be sunshine & sweet promises again. 68/

Diluc stared into his wine glass, not noticing how hairline fractures and cracks had spread across it like a spider web.

It would never work.

END 69/69

Thank you for reading any or all of that! I really appreciate ppl that have taken the time! :D
Let me know if you enjoyed it! Sorry for the angst, I wanted to show a conflicted Diluc, a Diluc's whose world of nobility & circumstances have corrupted and made miserable.

Hopefully it was still somewhat believable xD
I might eventually turn this into a fic so its easier to read and clean it up a bit, so lmk if u would like to see that!

also @ ppl that like every if not most of the tweet thread, I see you and I adore you! Thank you for taking the time with that ;v; 💗
