Work Text:
Diluc wakes up to a sharp pain in his shoulder, and an already raised morning boner rubbing between soft thighs. His minx of a mate dislodges his teeth from Diluc’s flesh with a sleazy grin on his face.
“Morning!” Kaeya greets with a chirp. Out of spite, Diluc is tempted to shove him away, but Kaeya pins his legs down with his weight, sliding downwards to lean down and mouth at the head of his cock.
The moan that escapes Diluc's lips is humiliating, but the failed aborted thrust of his hips that has Kaeya choking is good enough as petty revenge. But Kaeya continues to slide up and down his length, his lips stretching obscenely red around his girth, and Diluc runs his fingers through the silky blue curls of Kaeya’s hair, encouraging him to go deeper. And deeper Kaeya goes, until the tip of Diluc’s cock hits the back of Kaeya’s throat. When Kaeya swallows around him he nearly comes, but before Diluc can fuck his mouth Kaeya pulls off sharply all of a sudden.
“Kaeya...” Diluc groans, already keyed up. But he hears it too, the soft cries from the other room.
”I will go get her - see you later downstairs,” Kaeya says as he clambers from the bed, and rushes towards the bathroom sink to rinse his mouth.
Diluc watches his mate wrap himself with a bathrobe and run out of their shared room. He then sinks back into his pillow with a sigh, grimacing at his wilting, weeping erection. He has the urge to reach down and jack himself off, but he decides against it, choosing to go to the bathroom to wash up instead. If he comes he wants to do it with his mate, who he barely has time to spend with. They have been incredibly busy these couple of months, Diluc only returning from a four-day business trip last night, and Kaeya is off again with another escort work with delegates from Natlan.
By the time Diluc reaches the dining hall, Kaeya is already dressed, and Diluc has no idea where he hid his extra stash of clothes in. But in his arms is their pride and joy, their baby girl giggling at whatever soft whispers Kaeya has murmured into her ear, her little laughter sounding sweeter than the nightingales’ songs in forests.
Vennessa, the hero of Mondstadt, Falcon of the West. Diluc might not have cared for her association with the Knight of Favonius, Vennessa being its founder and all, but she was symbolic in many ways, holding and uniting the ideals and hopes both Diluc and Kaeya shared. When little Vennessa was born, with soft dark skin and crimson hair, a side comment from Venti about how much she looked like Mondstadt’s foremost hero ended her parents’ argument over her name. She looks a lot more like Kaeya, despite having the Ragnvindr’s signature hair - the red pupils of her eyes are in a peculiar diamond shape, and her lips are curled like a little kitten, a childish, innocent version of Kaeya’s catlike, often mischievous one. Diluc can’t help but smile as he walks towards his family.
But Kaeya’s greeting is a goodbye - a kiss on Vennessa’s forehead and against Diluc’s cheek.
”You are not having breakfast?” Diluc asks as he takes Vennessa from Kaeya and into his arms.
“There’s a general meeting this morning - the Knights are having breakfast together.”
”I see.”
”Don't be jealous,” Kaeya laughs heartily, before his voice softens for his daughter, “don’t bully your daddy too much, okay?”
Vennessa replies with a rather painful tug of Diluc’s hair, her baby fingers somehow finding her way to the ends of Diluc’s ponytail. Huh, Diluc ties it back to a high ponytail for a reason, who could have shifted it-
Before Diluc can burn a glare into his mate, Kaeya is already gone.
”If you put a ring on him, he may be able to stay longer,” Adelinde says as she places his breakfast onto the table.
Diluc snorts, “Unlikely. Mondstadt needs him.”
Even without an official marriage registration, everyone knows that they are together, with the proof of bond and scent and their child together. Kaeya isn’t going to stop being the Calvary Captain despite the more conservative members of society frowning at him, and Diluc isn’t going to stop his night time vigilantism either. They have a daughter to raise, and when it comes to duties Diluc and Kaeya are meticulous and efficient about fulfilling every demand. In any case, it’s not difficult work, with the entire Ragnvindr’s resources at their disposal.
But something has to give, and that’s their time with each other.
“Are you not asking for his hand?”
He already has his, but that’s something to be shared for another day. Diluc replies, “We are waiting until Vennessa gets a little older.”
Adelinde sighs, “You are just using that as an excuse to put it off.”
Right - she has been asking about it since news of Kaeya’s pregnancy spread. Diluc winces. ”... We will discuss a date.”
“Hm. Also, Master Diluc, do feed your daughter soon. She seems very hungry.”
Diluc looks down at the baby in his arms, who looks up at him with wide guileless eyes, the ends of his hair in her little mouth.
Oh no. This little spitfire.
Diluc brings Vennessa for all his civilian meetings, because, why not? Mornings and afternoons are Diluc's time to parent, while Kaeya has her for evenings and nights. Showing off your child is almost customary for aristocrats, but Diluc wants to keep her close to him as much as he can, especially when he has to leave occasionally for work. Besides, it's amusing when Vennessa throws a tantrum during a particularly boring meeting.
This meeting is with the Ragnvindr clan's oldest ties. Unfortunately, these people are a particularly conservative bunch, and Diluc can't afford to be particularly rude with this much money tied to them.
And the current Lord of the Alwin clan is staring at both him and his daughter with a frown.
"Can I help you?" Diluc asks politely.
Lord Alwin huffs. "You are young, and I am saying this for your own good - your mate should be here by your side, raising your daughter."
Diluc's eye involuntarily twitches, "Sir Kaeya is a rather important member of the Ordo, and he raises her as well. I assure you that Vennessa is in good hands."
"Oh? Then why do I hear news of your omega frolicking about with no-gooders in the taverns of Mondstadt?"
"Sir Kaeya," Diluc emphasises, barely restraining the anger from seeping into his voice, "has a job. I, as well as the citizens of Mondstadt who rely on him, trust him to know what is right."
Lord Alwin scoffs. Vennessa soothes her father with a soft nuzzle against his chest, and Diluc shifts his hold so that he can stroke her back.
"Your father would not have approved of this," Lord Alwin adds, and the rest of the members of the table start to murmur. Diluc has almost forgotten about them in this little standoff.
"He wouldn't have approved of me welcoming you to my house at your audacious insult upon me and my mate, but I have chosen otherwise, haven't I?" Diluc replies evenly, staring at Lord Alwin in the eyes. At that, Lord Alwin cowers, unbecoming of an alpha of his house.
"If there aren't any other complains about how I run my household," Diluc says aloud, and the entire room goes quiet to meekly pay attention to him, "let's start our meeting proper, shall we?"
At the end of the meeting, Vennessa is asleep in Diluc's arms. The members of the table leaves to proceed to the next room for refreshments. Lady Friedaweld pauses to gaze at Vennessa with a smile, before she regards Diluc with a nod. "It's Couples' Day today, isn't it? Are you and Sir Kaeya doing anything tonight?"
"We are having dinner together," Diluc replies.
"Just dinner? I remember when I was young, my mate and I used to go hunt for Regisvines during this night. I do love hunting for hoarfrost cores - they match her eyes, you see. "
Diluc blinks. "That's... intense."
"Both of you are fighters, aren't you? Young ones like you are always up to the wildest things. Heard the adventurous sort like to climb mountains to stargaze, the crazier even attempting Dragonspine. Dinner and calling it a night are for old folks like me, Master Ragnvindr."
"We... we will take your advice, Lady Friedaweld," Diluc stands up then, and hands Vennessa over to Elzer who is always by his side during these meetings. He takes Lady Friedaweld's hand and places a kiss to her hand, "Let's join the rest for the refreshments, shall we? We have your favourite qingxin tea prepared just for you."
"Always a gentlemen, Master Diluc. If you are planning to hold a wedding anytime soon give me a good seat, alright? I want to see the omega who has gotten you so smitten. I hear Sir Kaeya is as beautiful as he is charming."
"Vennessa looks a lot like him," Diluc says with a smile.
"Ah, a beauty, then. A family of beauties," Lady Friedaweld says wistfully, "if Crepus was still here he would have been painting portraits of you all and showing them off to everyone he meets."
Diluc laughs, a genuine one that he usually reserves for people in his heart, "Yea, he would."
Dinner plan is simple. Meet at 10 in the evening at the top of Starsnatch Cliff. Diluc will bring the drinks, while Kaeya is in charge of getting the food from the Good Hunter. Vennessa is cared for by Adelinde tonight.
By the time they reach the cliff, the place is crowded with couples and picnic mats, and the sight of two of the most famous people in Mondstadt inspire murmurs and gossip among the crowd. Even if the skies are showered with the most brilliant array of constellation, of course the attention is inevitably going to be on them.
Diluc tightens his grip around the handle of the basket containing the wine bottles, and whispers to his mate, "This is a bad idea."
"It'll be fine," Kaeya says breezily, dragging Diluc by the wrist to the side of the cliff where there's an empty spot. He puts his things down, and begins to set the picnic mat, taking out the sticky roast chicken he ordered from Sara from the basket. Diluc tries to help out by reaching towards the large bag that Kaeya has also brought along, but Kaeya smacks his hands away, asking him to take out the wine instead.
"Why are you in a rush?" Diluc asks, as Kaeya begins munching on his portion of the food barely minutes of setting up.
"I'm hungry," Kaeya replies easily, as he pats the empty space next to him. Diluc sighs, and sits at the spot Kaeya pointed to, and begins to eat. The late dinner and the long climb up have both of them rather ravenous, and they both finish their food quickly. Diluc then passes Kaeya his wine bottle, who accepts it eagerly, and takes out his own bottle of grape juice for himself, to Kaeya's grimace. They are drinking their respective drinks straight from the bottle, against all the etiquette drilled into both of them, because-
"You forgot to bring the glass, didn't you?"
"Why are you complaining?"
The two of them bicker, because that's what they always do, though the conversation shifts to their day, and they are in the middle of talking about work, when the screaming starts.
"We are under attack! Run!" Someone screams. Diluc stands immediately, hand reaching to grab his claymore. Kaeya is already up and running with his sword, and Diluc joins the fight immediately by his side. It's a Hydro Abyss Mage who has somehow thralled a hilichurl camp, one big enough to have two mitachurls charging along the smaller frantic hilichurls.
It takes longer than Diluc prefers, but the two of them are in sync in battles, and the fight ends with the Abyss Mage's ash scattered next to a dead ley leaves branch.
"Well, everyone's gone, huh?" Kaeya says as he surveys the scene. True enough, there's no one left at Starsnatch Cliff - abandoned picnic mats and half eaten food still left scattered around. Kaeya skips towards their picnic spot and picks up his bags.
"Let's set up a tent at the edge of the cliff!" Kaeya calls out.
When Diluc reaches his mate, the realisation hits.
"You set this up."
"Took you rather long to realise."
"...You are a menace."
"Can you help this menace of yours to set up the tent, pretty please?"
At Kaeya's request, Diluc sets up the fireplace in front of the tent, setting the wood alight with pyro as a finishing touch.
"Kaeya, are you done?" Diluc calls out.
No reply.
Sighing, he drags his feet towards the tent. A peculiar sensation from their bond hits him then, and he rushes forward. "Kaeya? Are you doing what I think you are doing?" he asks, as he pushes the cloth that covers the entrance of the tent to the side.
Diluc stills at the sight that welcomes him. The inside of the tent is dim, the only light source being the flames outside that seeps through the seams. But his mate shines both in the day and night, long turquoise hair spread around him in waves, his skin glinting gold under the dim light. His mate is naked, sprawled on top of furs and blankets he has laid out for the both of them. Between Kaeya's legs is what looks like a dildo with a red gem at its base, which Kaeya uses to pump in and out of his cunt.
"If people come back up..." Diluc says stupidly, his words trailing off as he stares slack-jawed at the fingers that begin to toy at his clit.
Kaeya rolls his eyes, "Then hurry up. I didn't take all the birth control potions and plan all this just for you to not fuck me after this."
Diluc kicks off his boots, and crawls into the tent. It reminds him of a traditional omegan nest, which Kaeya has only made for him once when they were teenagers. He pulls off his clothes, and lay them by the corner of the tent. When he returns to his omega, Kaeya is watching him with a bemused expression, hands no longer touching himself.
"No one is going to come into the tent," Diluc says, as he climbs on top of Kaeya, studying the lines of Kaeya's skin, his sharper edges and softer curves.
"Ahaha... What do you mean?" Kaeya asks, sounding a little nervous.
Diluc smirks, and leans into the crook of Kaeya's neck to breathe him in. He smells like wine, like lilies and ice. He smells like their mating bond, of Diluc's mark. He smells divine.
"They can come in if they dare," Diluc murmurs, and punctuates with a harsh bite over their mating gland. Kaeya cries out, arousal spiking through their mutual bond. His fingers move downwards, to where Kaeya is presenting with his parted legs, and traces the stretched lips of his cunt around the toy. When he breaches his cunt with a finger, Kaeya keens.
"Oh, oh, are you going to-"
"Can you take it?" Diluc asks as he prods his finger inside. It's a tight stretch, but Kaeya has prepared himself well, the insides of his cunt soaked in oil and his own slick. He pushes another finger inside, watching Kaeya's reactions carefully.
Kaeya spreads his legs wider, shaky hands gripping his own thighs. "My gift to you," he pants, "to do whatever you like."
Diluc leans down to press a kiss at his standing clit, to Kaeya's shiver. He can sense how much Kaeya wants to touch himself, how on edge he is.
His omega has prepared all this for him - it's only right to return the favour.
When Diluc pushes his cock inside next to the toy and bottoms out, Kaeya chokes.
It's too much, it's too much, but his mate is saying something soft and sweet into his ear, and the heat from his body is a source of support as Kaeya adjusts.
The thought of people outside hearing them already has his blood rushing to his brain in a frenzy, but oh, Diluc's right, isn't he? Who would dare? And who cares?
Kaeya's more distracted by the pressure inside his cunt, Diluc's alpha dick and the toy Kaeya brought just to prepare himself for said dick, both within him.
Diluc is holding him against his chest, and Kaeya is sprawled on him, breathing raggedly as he clenches weakly around the intrusion. Kaeya has wrapped his arms around Diluc's neck for support, his nails clawing lines on Diluc's back as he shifts inside him. Diluc hushes his whimpers with soft encouragements against his ear, and his free hand rubs quick, electric circles around his clit.
"You ready?" Diluc asks.
It takes a moment, but Kaeya nods.
And Diluc moves. Slowly at first, each thrust a burst of burning ecstasy inside, and Kaeya doesn't know how he's taking it, but he is, and he breathes through the zigzagging blend of pain and pleasure, Diluc igniting the boiling arousal simmering within him. There's a hand holding the base of the toy, slowly pushing it in and out of Kaeya in time with Diluc's thrust. In the back of his mind he knows what Diluc's doing - they haven't had sex together in so long, and after this it will be a miracle if they have time for each other again, and Diluc wants to make it something Kaeya won't forget.
"Alpha, go faster," Kaeya moans against his palm.
A groan, and the pressure in his cunt turns intense as Diluc starts to fuck him properly, each jab going deeper inside him, reaching places the toy cannot. Kaeya knows he can go faster and harder, and he rather has Diluc lose control to take him the way he wants it. So he taunts against Diluc's ear, "Thought you wanted everyone to hear me?"
In a blink of an eye, their position is switched - Kaeya on his back, his hands pinned to the mattress, and Diluc is inside him, pounding into his cunt with an obscene wet squelch. Like this, there's nothing to stifle his cries, and Kaeya wails as Diluc reaches deep enough to fuck against his womb. The head of his cock strikes the opening there, and Kaeya can feel it starting to give with each violent thrust of his alpha's cock into him.
Diluc lets go of Kaeya's hands so that he can lean in to kiss him, and this kiss is open and dirty as it leaves him breathless, reminiscent of how they are fucking below. Kaeya can barely think, the onslaught of pleasure leaving his mind an utter blank, and his body feels distant from him, simply a mess of desires for his lover to indulge. He doesn't realise that he's crying, that he's turned into a weak drooling mess, that his alpha is sucking hickeys down his neck and onto his nipples, leaving a trail of red and purple down his skin.
Kaeya feels something dislodges from inside him, and a rough shove, and oh - that's Diluc's knot that is taking the place of the toy, that's Diluc's cock breaching the opening of his cervix in the same stroke.
He screams, the orgasm ripped out of him just like that. He barely registers the warm burst of come flooding into his womb, though the swirling, heavy weight of Diluc’s seed sinks him in a brief wave of hazy comfort, omegan instincts towards being bred activating.
When he comes down from his high, he finds that they have changed positions again, back to the one earlier where he's on top of Diluc and in his arms. The knot inside him has barely subsided, and Kaeya tries to shift around it, only to elicit a moan from both of them.
"You're back," Diluc reports rather cheerfully, "you passed out for a bit there."
Kaeya tugs his hair for that, "Shut up. I forgot how crazy you get."
The hand that was stroking his back slides downwards, and rubs at his ass before sliding between the cheeks. Kaeya feels a finger stroke at the rim there, and shudders.
"Don't tease," Kaeya complains.
Diluc slips his finger inside, wet from the release that had spilled out of Kaeya's cunt when they were fucking just now. One turns to two, then three, and then Diluc replaces his fingers with the toy. Kaeya sighs as he feels it stretch the tight channel of his ass.
“Have you been playing with yourself like this?” Diluc asks against his ear.
“Ha- of course. You aren’t here.” The toy that is languidly fucking him suddenly jabs upwards hard, and Kaeya bites into Diluc's shoulder to muffle a scream.
”And what do you think about?”
”Who else? You- yes, yes fuck baby right there! Ah!”
”Answer me, sweetheart.”
”You, you!” Kaeya chants as he sobs at the pressure building him from both ends, “It’s only you.”
Diluc smiles and drops a kiss against his hair. “Good."
He's so full like this, a knot in his cunt and a toy inside his ass, and Diluc doesn't give him any break, grinding his knot into his cunt and fucking into his womb while the toy jackhammers into his ass. Kaeya slips a hand between them to touch himself, and a few frantic rubs of his clit sends him over the edge, his cunt pulsing over Diluc's cock as he clenches tightly around the toy.
By the time Kaeya has come down from the aftershocks of his orgasm, the knot has subsided and the toy has been removed, and Diluc gently pulls out of him and lays him down onto the soft sheets. For a moment, they indulge in the silence and the satisfaction of their sex afterglow, curled into each other, sweaty and breaths slowing down from the previous high. Kaeya can feel Diluc's release sliding out of him slowly, and it will be a hassle to clean after, but for now he hums in approval of being marked by his alpha inside him after so long apart. He won't get pregnant from this, and frankly speaking he doesn't think he's ready for another child currently, though the idea of having a big family has his heart fluttering.
His alpha's arm is around his waist, and Kaeya slides his palm up to feel the steel-like muscles under pale skin. Forearm, biceps, shoulder, neck, jaw. Kaeya rests his palm against Diluc's cheek, and asks, "Are they still giving you trouble?"
Diluc has been watching his omega with a soft expression this entire time. "About?"
"Me. Vennessa. Mostly me."
Diluc hums, "Nothing I can't handle. To be fair, it's not really about you. It's about me."
"Ah. The world revolves around you, Master Diluc," Kaeya says sarcastically. Diluc pinches him in the side for that.
"I'm serious. Is there anything I can do to help?"
"... They aren't wrong about how we haven't been spending time together."
"I can set up a public show-"
"-Not that," Diluc shifts to take Kaeya's hand and intertwine their fingers together, "I don't care if they see us or not. I just - I haven't seen you in awhile. Vennessa hasn't seen us altogether in awhile."
"Oh," Kaeya says, and his gaze turns solemn, "it's hard to-"
Diluc squeezes his hand reassuringly, "I know."
"I'm not trying to make excuses, I just," Kaeya drops his face into Diluc's shoulder, "I want to give Vennessa the best. For me, being able to spend my childhood with you and Master Crepus was the best. I thought, as long as she has that, just something like that, she will be fine."
"And she will be fine. Vennessa is a very lucky baby. It's... it's not really about her. I miss you, that's all."
Kaeya gazes up at Diluc, hoping he can feel the love for him in his heart through their bond like this, his beautiful mate who looks like rubies under moonlight, "I miss you too."
