#luckae TW// a/b/o / bitching / mpreg

Crepus didn’t die on that stormy treacherous night. He was badly injured though, enough to permanently disable him. Diluc was distraught, and Kaeya broke down and admitted everything about his past and identity. Begging for forgiveness.

But Crepus had already known. He’d known since he found Kaeya, had seen the star in his eye and intricate black markings over his other. But he’d wanted to give Kaeya a good life regardless. He was just a child and children should not have to carry the sins of their parents.

Diluc was furious, thinking their time together, their friendship, had been nothing but lies. But listening to his father, and seeing how desperately Kaeya clung to Crepus, tears staining his cheeks. Diluc found he couldn’t blame him.

Not after hearing of what happened to his nation, his family.

He never wanted to see Kaeya like that again. Broken, sobbing, mourning his past and the family he had chosen to move on from.

Kaeya had chosen them. He had chosen Diluc over the family he mourned and had promised to avenge. So Diluc would do as Crepus did, and give Kaeya the best life he could possibly have.

An idea sparked to life that night. He would give Kaeya a family to replace the one he lost. A simple idea, but it grew into a fully fleshed out plan for their future. Yes. He would be the one to make Kaeya happy. He would be the one to give Kaeya everything he could ever want.

They were both young, neither had presented, but Diluc had already started showing signs of being an Alpha like his father. It was perfect for his plans. But Kaeya had yet to show any signs of presentation. And his plan required Kaeya’s body to be …receptive.

He went to his father with his thoughts.

“Wanting to give Kaeya a happy life and a family is admirable, son, and I’m proud of you.” Crepus said, patting Diluc on the shoulder. “But there is no guarantee that Kaeya will present as an omega.”

Crepus pursed his lips “Don’t misunderstand. Antiquated ideas that two Alphas should not be together are not what this family believes. But you may have to think of other means if that is how Kaeya presents.”

The very idea struck Diluc as wrong. Kaeya would be an omega. His omega. He wasn’t against adoption. But it would be pointless to replace Kaeyas lost family with one that shared none of his blood. Not to mention the image of Kaeya swelling with HIS children was too perfect.

He was sure that Kaeya would be an omega. He was so beautiful and caring, and he would be the perfect mother for their children. But his fathers words stayed in his mind, and a desperation filled him.

It started with research on the earliest signs of an omega presenting. He searched Mond for every book on the subject, and it was in a shady little alley shop that he came across a book that introduced him to a certain process…

Bitching.

It wasn’t a thick book, more a pamphlet with a cover than anything. But it sparked something in him. Kaeya WOULD be an omega. His omega. And now he had a way to ensure it.

To be continued! In other news, as of half an hour ago I am fully vaccinated!!! 🎉🎉🎉

He waited for a few weeks. He wanted to make sure he knew absolutely everything about the process before he began. He would never do anything that could potentially hurt Kaeya.

Then Kaeya finally showed signs of presenting. And all of them pointed to Alpha.

Diluc began the process immediately.

It started simply. He already spent most of his time with Kaeya, it wasn’t hard to get closer. He draped himself over the younger boy whenever he could, rubbing his scent all over him and shoving Kaeya’s face into the crook of his neck where his scent was strongest.

He also started brushing touches against Kaeya’s scent gland. When Kaeya grew used to the touches they became firmer. Squeezes that flushed Kaeya’s cheeks, firm enough for Kaeya’s instincts to recognise Diluc’s dominance, but brief enough to be brushed off as a friendly gesture.

He also started giving Kaeya demands. Being a higher rank meant he was able to do so without suspicion. And Kaeya obeyed so beautifully, always eager to please.

Diluc had to suppress his excitement. He’d started the process before Kaeyas instincts could tell him submitting was against his nature.

The next step was harder, but only in avoiding suspicion. Diluc made a point to start reading cook books in front of the staff so when he approached them with an interest in learning to cook they didn’t question it and let him help with dinner preparations.

He prepared for this step before cooking started. Retreating to the bathroom, he got himself off to the image of Kaeya; swollen belly and tits, glowing with pregnancy and begging Diluc to ravage him. After that it was simple to sneak a vile of his cum into Kaeya’s serving.

Seeing Kaeya eat, unknowingly swallowing Diluc’s cum as he smiled and made small talk, made Diluc’s cock strain in his pants. It was getting progressively harder to restrain himself from simply pinning Kaeya to the nearest flat surface and fucking him full of cum directly.

Maybe it was the overwhelming need to breed Kaeya, or it was simply his time. But that night, filled with fantasies of stuffing Kaeya full of his cum, Diluc presented.

Finally. He was an alpha.

Everything he was doing would be so much more potent now. Kaeya would be his. His omega. His to fuck and fill. His to breed.

Soon…it would happen soon.

Feeding Kaeya his cum was one of the last steps, and it would work even better now with alpha cum. But it needed to be done multiple times before it took effect. In the mean time Diluc continued the other steps.

Every day he covered Kaeya in his scent. He also began to massage Kaeya’s scent gland under the guise of shoulder rubs until Kaeya was automatically presenting his throat to Diluc when he moved in close. A perfect act of submission.

Diluc’s displays of dominance became more obvious as well, as was expected for a new alpha. And Kaeya’s compliance came more naturally. He almost seemed eager to receive Diluc’s orders, and carried them out with perfection every time.

After a week of feeding Kaeya alpha cum Diluc finally began to see a change in Kaeya’s presentation symptoms.Kaeya had stopped getting irritable so easily. He’d also lost the resolute stubbornness that came with being an alpha. Which made taking care of him so much easier.

Most importantly, he’d started wearing softer clothing, and Diluc found some of his shirts missing from his closet. He’d been confused at first, then, a wide smile had spread across his face.

Collecting and wearing soft clothes was a sign of omega presentation. Their bodies growing more sensitive and a rising need to nest pushed them to steal clothing from the people they felt safe with.

Paired with the submission he showed Diluc every time he bared his neck, and the eagerness to obey Diluc’s orders, there was no doubt that Diluc’s plan was working.

It was time for the final step.

For the bitching to be absolutely successful Diluc had to do one more thing. Since he was still helping the maids make dinner it was simple to mix sleeping powder along with the cum into Kaeya’s food.

That night, with the household asleep, his father too wounded to do his usual nightly check ins, and the assurance that Kaeya wouldn’t wake no matter what happened, Diluc made his way into Kaeya’s room.

TW/// somnophilia, boypussy and noncon ahead.

Kaeya was sprawled out on his back, limbs haphazardly spread across the bed with his blankets strewn messily over him. It was adorable. How lax he was. It was also perfect for what Diluc planned to do.

It was easy. So easy to slide Kaeya’s sleep pants off. The slow reveal of his supple, tanned legs was so arousing Diluc had to hold himself back from biting into the soft flesh of Kaeya’s thighs. He had a goal, and though he had drugged Kaeya, he didn’t want to chance him waking.

Diluc swallowed thickly at the sight of Kaeya’s clothed cunt. It was so close. All he had to do was slide Kaeya’s underwear to the side and he would have full access. With slightly trembling fingers he did just that, revealing the plump pussy nestled under Kaeya’s cock.

Once his plan was successful Kaeya would keep the delicious hole Diluc had revealed. To think, if he hadn’t set about Bitching Kaeya he would have lost this delicacy. And it was so beautiful on Kaeya. It would have been a true tragedy.

Gently, and with reverence, he parted Kaeya’s lips and slid his finger over the pink opening. It twitched invitingly under his touch, and he groaned with barely restrained lust. He couldn’t just dive right in, though he was sorely tempted.

He straddled Kaeya’s thigh and pulled his own pants down enough to pull out his cock. Hard and heavy in his hand, he moaned as he locked eyes on Kaeya’s sleeping face and began to pump himself with one hand. The other slowly started to stroke Kaeya’s opening.

He rutted his hips against Kaeya’s thigh, and as soon as is fingers slid through thick slick he went to work. Opening Kaeya up was a slow process. He was so tight, and he squeezed around Diluc’s finger so hotly he had to stop himself from cumming then and there.

He squeezed his cock tightly and grit his teeth. He had to reach the deepest part of Kaeya before he let himself cum.
Kaeya shifted, hips twitching, and Diluc snapped up to watch him for any sign of waking.

But Kaeya just moaned quietly, and settled back into sleep. Diluc sighed in relief, then grinned. He’d done that. He’d made Kaeya moan. And as soon as he’d succeeded in bitching him, he would make him scream.

Spurred on, he slid a second finger into Kaeya, and revelled in the soft sigh that came from the sleeping boy. He moved gently, thrusting his fingers into the hot pussy that was rapidly becoming drenched in slick.

It wasn’t long until Kaeya was rolling his hips, unconsciously pushing Diluc’s fingers deeper. He let out breathy moans and sighs whenever Diluc’s fingers massaged deep within him and scissored him apart.

“Mnnn…” Kaeyas back arched up, and finally, finally Diluc’s fingers brushed against the deepest part of him. He moaned with excitement and pleasure, and pulled his fingers out of Kaeya’s hole with a wet slide.

With a hiss he wrapped his soaking fingers around his cock and let himself cum. He bit back a moan of Kaeya’s name and caught his cum in his hand, collecting as much as he could. Then, gathering his spend on the fingers that had opened Kaeya up, he thrust back into Kaeya’s cunt.

Kaeya gasped, but didn’t wake, and Diluc took it as a sign to go harder. He thrust back into the deepest part of Kaeya, purposefully rubbing his cum covered fingers against Kaeya’s cervix.

This was the final step. All he had to do was make Kaeya orgasm, and his womb would open and accept the alpha cum that stained its entrance. Once Kaeya’s womb tasted his cum it was over. Kaeya would be his omega.

The book had suggested fucking the burgeoning omega, but Diluc wanted to wait. He would take Kaeya on his first heat, after Kaeya begged for him, begged to be his mate, to be filled with Diluc’s cock and cum.

He could see it perfectly. Kaeya was already responding so beautifully to him. Arching his back, rolling his hips, squeezing around his fingers and moaning so sweetly. He would take Diluc’s cock so well.

He wanted to kiss Kaeya so badly, to play with his body and see how sensitive it was. But he held back. Again, he wanted to save it for Kaeya’s first heat. They would learn each other’s bodies together as they became a mated pair.

Diluc was drawn from his fantasies when Kaeya’s breath hitched and his hips began to tremble. Diluc groaned at the feeling of Kaeya’s walls fluttering around his fingers, desperately drawing them deeper.

This was it. Diluc rubbed and thrust harder into Kaeya, curling his fingers just how he read about in preparation for this.

Kaeya’s hips rose off the bed, and with one last thrust against his cervix, he let out a cry and his pussy clamped around Diluc’s fingers. He felt the moment Kaeya’s womb opened to accept his cum, and slick gushed over his hand.

He groaned in delight at the image Kaeya made, falling apart with his orgasm. He was made for this. So beautiful. Diluc couldn’t want to make him cum like this while stuffed full of cock.

“D-Diluc…” Diluc flinched, eyes snapping up to Kaeya’s face. He was sure he’d been caught. But Kaeya was still asleep, chest heaving and body trembling, but asleep. “Diluc.”

The sigh of his name fell from Kaeya’s lips like a prayer, and Diluc’s heart soared with the realisation that Kaeya was dreaming about him while his body was taunt with pleasure and riding the waves of an orgasm.

“Soon, Kae.” Diluc promised, reaching to caress Kaeya’s flushed face.

He was gentle as he cleaned Kaeya up, wiping up the cum and slick that stained his skin and the bed under him.

He carefully cleaned Kaeya’s pussy too, though he didn’t go deep enough to disturb the cum near his womb. Just enough to not raise suspicion upon Kaeya waking.

The book had said the chances of presenting mere hours after the last step were high, in which case Kaeya wouldn’t notice anything amongst the mess of a presentation, but Diluc couldn’t take the chance.

He was loath to leave Kaeya, but he couldn’t spend the night without Kaeya realising what he’d done. So he quietly made his way back to his room and tried his best to fall asleep despite his excitement for the next day.

His plan to ensure Kaeya’s body was receptive to him was complete.

Soon his plan to give Kaeya a family would begin. He couldn’t wait to breed his omega.

To be continued! Two updates in one day??? What is this thing called motivation?

Thread somehow got split here so continue from here:

https://twitter.com/ChickennSalt/status/1446334938530205702

The morning came quicker than Diluc expected. He’d managed to fall asleep after getting himself off again. The sight of Kaeya’s pussy sucking in his fingers so eagerly replayed in his dreams. It was the best sleep he’d ever had.

He woke to frantic knocking on his door and a weak voice calling his name. He shot up, sleep fading in place of panic. Had something happened? Was there an attack? Was his fathers condition worse?

Then he remembered what he had done last night, and he recognised the voice at his door. It was Kaeya.
Excitement filled him, and he threw off his blankets and rushed to let Kaeya in.

Kaeya nearly fell through door when it opened, legs seeming unable to hold his weight. Diluc caught him and pulled him close, a flash of worry going through him at how limp Kaeya was.

“Kae? What’s wrong? Did something happen?” Kaeya looked up at his words, and Diluc sucked in a breath. Tan cheeks were flushed a deep red, and the starry eye that stared up at him was watery with tears.

“Luc.” Kaeya hiccuped, lower lip wobbling “I feel strange.”
It took all of Diluc’s restraint to hold back a triumphant grin. He’d read so many books about omega presentation. He knew the signs. Kaeya was going through some of the symptoms of a heat as his body shifted.

Diluc couldn’t wait for the shift to be finished. He wondered if Kaeya’s body would look different. How would his scent change?
A whimper fell from Kaeya’s lips before Diluc could fall into fantasies, and he snapped his attention back to the suffering omega in his arms.

He caressed Kaeya’s flushed cheek and tutted with sympathy, pretending to be clueless. “I’ll take you to Father, he’ll know what’s wrong.” He leaned down to scoop Kaeya up into his arms, hands firm and sure in their hold, and Kaeya automatically nuzzled into Diluc’s neck.

He bit back a groan at the feeling of Kaeya’s lips brushing against his gland, seeking comfort from his future alpha. With Kaeya’s face hidden away in his neck, Diluc felt no need to hold back his grin.

He’d done it. Kaeya was an omega, and soon, he would be HIS omega. He knew Kaeya would be perfect like this. He was already seeking out his Alpha, had gone straight to Diluc when he woke up feeling strange, and he was so sweet as he whined and nosed at Diluc’s scent.

Kaeya squirmed slightly in Diluc’s arms, thighs rubbing together, and he whimpered. “Hot…” he mumbled into Diluc’s neck.
“We’re almost there, you’ll be okay.” Diluc shushed him gently and kissed the crown of his head.

Adalinde met them at the door to Crepus’ room. Normally she would be preparing to help Crepus down to breakfast, but upon seeing Diluc carrying a feverish Kaeya she hurriedly ushered them in.

Diluc dutifully went along with the act and put on a worried expression to greet his father with. “Father, I think Kaeya is sick!”
Crepus frowned from where he was sat, propped up with various pillows in his bed. His eyes fell on Kaeya and he pursed his lips. “Bring him here.”

Diluc hurried to sit on the edge of the bed, tucking Kaeya securely onto his lap, and Crepus hummed down at the flushed boy.
Diluc watched Crepus’ expression carefully as it smoothed with understanding, then, for an instant, he looked up at Diluc with poorly hidden excitement.

“Should we call a healer?” Diluc asked, continuing his act of worried ignorance, and Crepus shook his head.

“He’s presenting, it’s perfectly natural.”

“Presenting?” Kaeya perked up a little, but his expression quickly turned to a petulant pout and he folded his arms over his chest with a huff. “Diluc didn’t have to go through this. He was just grumpy for a day.”

“My dear boy.” Crepus laughed heartily. “Diluc is an alpha, of course his presentation would be different to that of an omega.”

“An omega?” Kaeya looked stunned, his eye going wide and his cheeks flushing impossibly deeper. Almost imperceptibly his eye flicked up to Diluc, shy and… hopeful? Diluc had to clench his teeth to stop a whole body jolt of satisfaction.

Kaeya wanted him. Of course he wanted him, Diluc was clearly the best, no, the only choice of alpha for him. And he had spent so long cultivating Kaeya’s instinctual reactions to him.

All that time smothering Kaeya in his scent, driving him to instinctually search it out for comfort. Night after night of feeding Kaeya his cum, developing his taste for it, building the foundations of a craving.

He readily submitted even before presenting. Kaeya was already his.He just had to make Kaeya realise what his body was already telling him. He would subtly introduce the idea that they would be perfect mates. And he would do it by showing Kaeya just how good an alpha he could be.

“You should take the day for yourself.” Crepus said to Kaeya, snapping Diluc from his mental planning. “I’ve heard omegan presentations can be a little rough on the body. Get as much rest as you can and drink plenty of water.”

Kaeya nodded and looked up to Diluc with a pout “Will you take me back to my room Luc?” It was the perfect opportunity to begin showing off just how good a provider he was. He nodded and left his father with a promise of sharing breakfast with him once he’d gotten Kaeya settled.

Kaeya’s room smelled of slick and his sweet pre-presented scent, with the barest hint of elemental iciness. Soon it would deepen into a ripe, fertile omega scent. By the end of the day Diluc figured. He couldn’t wait.

Kaeya bit his lip and blushed when Diluc laid him down. He was probably embarrassed by the scent, not realising Diluc’s excitement. “Do you need anything?” He asked, pushing a lock of silken blue hair behind Kaeya’s ear. “Anything you need. Anything. I will give it to you.”

Kaeya looked up at him with such awe Diluc had to clench his fists to keep from pinning him down on the bed then and there. He wanted to beg Kaeya to accept him as his mate, to allow him the honour of giving his future mate everything he could ever want.

But Kaeya snapped out of his daze with a blink. He looked down at his lap and squeezed his hands together “I-I think I just need to sleep. Maybe you could bring me some lunch after my nap.. and… keep me company ?”

He nodded and stroked Kaeya’s hair “I’ll be back at noon then.” He promised with a reassuring smile “I’ll bring your favourite novel and some card games.”
Kaeya nodded eagerly and thanked him, taking his hand in a lingering hold as if he couldn’t help himself but cling to Diluc.

A perfect beginning in Diluc’s opinion. Kaeya’s smile was surer, and Diluc left him to rest, happy that he’d planted the idea of Kaeya relying on him more. He strode into the dining hall with a smile he couldn’t possibly hope to hide, and met an equally happy seeming Crepus.

“You seem happy, son.” His father greeted, a knowing smile quirking his lips “Excited that Kaeya’s presentation follows the course of your plans?”

“There was never a doubt.” Diluc said calmly as he sat at the table “It could only ever be me that gives Kaeya happiness. His body knows that now and presented accordingly.”

Crepus sighed wistfully and leaned back in his chair, idly spearing a grape on his fork. “I must admit to some excitement.” He said, eyes gleaming as they met his sons across the table “Some grandchildren would keep this old home bound man well entertained.”

Diluc’s grin turned sharp and eager. “I shall endeavour to make it happen soon then. Im sure Kaeya will be more than willing once I bring the idea to him.” He smiled fondly at the thought of how excited Kaeya would be. “I’ll finally give him the family he deserves.”

To be continued! No smut in this update but it’ll probably get be getting steamy next time~

Noon saw Diluc eagerly striding out of the kitchen with a loaded plate of easy to eat food for Kaeya. A stack of skewers, fresh fruit, and a glass of juice. Before he went to Kaeya’s room though he slipped into his own and locked the door behind him.

Patience was never an issue for Diluc, but his fathers words spurred something inside him, an excitement that coloured his judgment. He placed the tray of food on his desk and flipped to the last page of the bitching book.

He was going to wait at least a week for this. Let Kaeya settle into his new body and it’s needs. But his fathers wistful musings about grandchildren, and the attraction that was already so obvious in Kaeya, eased any guilt Diluc felt as he gathered the herbs the book listed.

He stirred the right amount into Kaeya’s juice, then, for good measure, he sprinkled some in the food as well. Once that was done he used his vision to light the fireplace, and with one last lingering look and silent thank you, he threw the book into the flames.

He’d done what was needed to ensure Kaeya’s happiness. The book had served it purpose and he couldn’t let anyone find it. Once it was set alight and burning nicely he gathered the tray and finally headed to Kaeya’s room.

Kaeya was asleep when Diluc slipped in. Instead of the usual sprawl he was curled up on his side, tucked securely under a blanket. Diluc set the tray on the side table and sat beside Kaeya on the edge of the bed, taking a moment just to admire his future mate.

Kaeyas lashes fell upon his cheek, long and dark against smooth tan skin. His hair was loose and tussled, framing his face and curling over his shoulders like dark, curling ink.

His eye was free of its ever present patch, and Diluc took a moment to admire the black starry markings that curled over it. A scar or birthmark, Kaeya had never told them. But Diluc had always found it beautiful. A shame to keep covered.

The image of Kaeya so lax and docile, just as he had been last night, was irresistible. With the lightest of touches Diluc traced from Kaeya’s temple to his jaw, then down his throat to the crook of his neck.

It was so tempting to lean down, to nose at the flesh of Kaeya’s shoulder, to his mating gland where his scent was strongest, and sink his teeth in. His touch unconsciously grew heavier with his thoughts, and Kaeya let out a sleep whine.

Diluc quickly moved his hand so it was on Kaeya’s shoulder, just in time for Kaeya’s eyes to flutter open, one a starry blue and the other a glittering gold. “Mmmn… Luc?”
“Its noon, Kae.” Diluc murmured “You should eat something.”

Kaeya smiled up at him, bright and sleepy, and sat up. The movement shifted the blanket, and with it, a wave of Kaeya’s scent was released into the air. It took everything in Diluc not to pounce on Kaeya then and there.

Not only had Kaeya’s scent become sweeter and deeper, it had taken on a unique flavour; freshly fallen snow, calla lillies by the lakeside on a foggy morning, and delectably; the freshly baked cookies Diluc and Kaeya favoured as children. A guilty pleasure they still both shared

It was a sign clear as day. Kaeya was made for him.

“Ah…” Kaeya’s hand flashed up to cover his marked eye, shame and a hint of fear flashed across his face. It snapped Diluc out of his thoughts immediately, and he took kaeya’s wrist with a gentle shush.

“You don’t have to hide from me, Kaeya. Never.” He assured, pulling Kaeya’s hand away from his eye. He brushed Kaeya’s hair from his face and smiled warmly “There.” He said, as Kaeya’s eye was uncovered. “Perfect.”

Kaeya flushed, then he leaned into Diluc’s touch, nuzzling into his palm perfectly. “Shut up, ‘m too sleepy for your teasing.” He whined, shoving at Diluc’s shoulder with a laugh. “You promised food and entertainment!”

Diluc smiled fondly and nodded. He passed Kaeya the tray of food and juice, and watched him scarf it down with barely restrained excitement. He hadn’t added any cum to this meal. No. The herbs made that unnecessary. Kaeya would get his fill a different way tonight.

Once all of the food and juice were finished Diluc pulled a pack of cards and a book from his coat pocket. They played a few rounds of poker, then Kaeya settled back into his pillows, deciding his winnings would be chapters he wanted Diluc to read from his favourite book.

It took precisely 2 chapters and three pages for Kaeya to start shifting slightly under his blankets. Another chapter later and his cheeks were flushed brightly and his scent had grown overwhelmingly sweet. It was almost time.

Diluc pretended not to notice Kaeya’s growing discomfort, his voice remaining even and soft as he read from the book. A perfect act. It wasn’t until Kaeya couldn’t take it anymore that he stopped. “D-Diluc… I… I think I need to be alone.” He groaned weakly, chewing at his lip.

“Is something wrong? Should I fetch Adelinde? Or father”
“No! I mean… I think I just need more rest!” Kaeya laughed, nervous and jittery, and hurried to push Diluc off the bed until he stumbled to his feet. “I’m just gonna… sleep! Yeah, sleep.”

Diluc nearly growled in delight at the dazed look in Kaeya’s eyes. How they flickered down Dilucs body and lingered on his crotch before snapping away with a shaky breath. “I can help you.” He said calmly despite his pounding heart “Whatever’s wrong I can find a way to help.”

Kaeya almost gave in then and there, it was clear in the way he swallowed thickly, throat bobbing, and stared up at Diluc with wide eyes. His mouth opened and closed, then snapped shut and Kaeya shook his head. “N-nah… I’ll be fine! It’s just… a presentation thing… I think.”

Oh it was more than that. It was rare for an omega to go through a full heat the day they presented, but it wasn’t unheard of. This would be chalked up as one of those times. Kaeya simply developed faster than most omegas. No one would ever think Diluc had spiked Kaeya’s food.

“Okay.” Diluc soothed, patting Kaeya’s head one last time. The way Kaeya leaned into the touch, a low whine falling from his lips, was nearly too much to resist. But Kaeya had to be further into his heat before he could let himself accept what his body needed.

“I’ll come check on you in half an hour.” He promised, knowing Kaeya was already too out of it to protest the idea. “Rest well. And remember, I can give you anything you need Kaeya. Anything you want.”

He turned on his heel, clenching his fists to resist the dismay in Kaeya’s whines as the omegas instinct cried for his alpha. He closed the door behind him, solid at his back, the only things keeping him from bursting back into that room and ravaging Kaeya like they both wanted.

Soon. Soon Kaeya would be so lost in instinct and need that he will forget everything holding him back. All those mental hang ups that prevented him from accepting Diluc as his alpha. His body already knows the truth. All Diluc had to do was wait for the heat to take his omega.

Then Kaeya would beg for him. Beg to be his omega, his mate. And Diluc would give him everything he asked for, everything he needed. He would be the perfect alpha. And once Kaeya’s heat was over there would be no room for doubt or denial in Kaeya.

Because by the end of this heat Kaeya would be pregnant with Diluc’s first child. And he will realise that this was everything he ever wanted. Everything he desired on stormy knights when his gaze grew far away and wistful. All Diluc had to do was be patient.

He informed a passing maid to section off the area of the house so Kaeya wouldn’t be disturbed during his heat. She seemed surprised by the development, but nodded in understanding. Then, Diluc waited.

Just as half an hour was creeping closer, the muffled moans that had been seeping through the door rose in volume, and a single strangled cry speared straight to the core of him.

“Diluuuuc~”

Diluc tore through the door. He had had a plan. Play the dutiful brother. Act as if he was just checking in. But that all went up in flame the moment that cry lit upon his ears. And the sight that met him through the door stripped him of his ability to keep up the act.

Kaeya presented himself in a mouth watering display. Face down, biting at a tear soaked pillow. Ass waving in the air tantalisingly. And With a gulp Diluc’s eyes fell on Kaeya’s hand, which desperately pumped a thick, glistening icicle in and out of Kaeya’s flushed leaking cunt.

So desperate for a cock, Diluc’s cock, Kaeya had used his vision. All that power and Kaeya was using it to fuck himself while moaning Diluc’s name. It was so perfect, so arousing. Diluc almost wanted to stay and watch as the icicle melted and dripped down Kaeya’s pussy and thighs

“Diluc— Diluuc!” Kaeya moaned, driving the icicle deeper and sobbing in frustration. Slick joined the melted ice to trail down his legs but it could never satisfy him, Diluc knew that. Only the hot flesh of a cock could sate an omega in heat. And only Diluc could satisfy Kaeya.

So when Kaeya sobbed out his name again, desperate and pathetic, Diluc let out an animalistic growl, and was across the room in seconds.
“Kaeya, my Kaeya, look at you. Perfection.”

Kaeya gasped and his dazed watery eyes snapped to Diluc. Immediately he whined, high and needy, and his attempts to fuck himself on the icicle faltered.
“Luc?” He cried, then struggled to sit up. “Luc Luc Luc!”

Kaeya threw himself at Diluc, immediately shoving his nose into Diluc’s neck to scent him. Kaeya’s heat scent up close was intoxicating, and Diluc breathed it in like a starving man.

“Please Diluc, You promised! You told me you would give me anything I want!”

Diluc purred down at the Omega and wrapped his arms securely around him, shushing him and running his hand up and down his spine soothingly. “Anything, love. Just say it.”

“You!” Kaeya sobbed and pulled back to look Diluc straight in the eye “I want your cock Diluc.” He begged “Please give it to me. Nothing I do is good enough! Please fuck my pussy with your cock! I need it!”

That was all he needed. He pushed Kaeya back onto the mattress with a snarl and forced his legs apart until Diluc could fit snuggly between them. Then he went straight to attacking Kaeya’s throat, littering it with bites and kisses that made Kaeya gasp and moan.

“Mmn.” He groaned against flushed skin “I can’t want to see you beg so sweetly while stuffed full of cock. You want that don’t you?To have my cock fuck you full and give you everything you ever wanted?”

“Yes! Gods please!” Kaeya gasped, tossing his head back to give Diluc more access to his throat “I want it! I want your cock to fuck my pussy! I want Diluc inside me so bad! It’s all I want! All I was made for! Please Alpha!”

Finally.

Diluc grinned, sharp and predatory. He wouldn’t leave this room until Kaeya wore Diluc’s mark on his neck and his belly was swollen with seed and already growing with life. He couldn’t wait to get started.

To be continued!!!! Bet you didn’t think the poll about Kaeya having a vision was for this reason huh?

Another split happened so continue from here:

https://twitter.com/ChickennSalt/status/1447161418738847752

Kaeya looked so beautiful laid out beneath him. Already so stunning even without a full transformation. If Diluc had given him a week after presentation for his body to settle maybe his hips would have widened, his breasts filled a little.

It wouldn’t be long until his body blossomed into omegahood anyway. If anything, knocking him up would hasten the process and make for an even more provocative change.

As it was, heat made a mouthwatering image of Kaeya already. His skin flushed in all the right places, highlighting glazed mismatched eyes and dark biteable nipples. His pussy and cock were so red, leaking and swollen with desperation.

It was so tempting to tear off his pants and fuck into Kaeya straight away, but this night was special. It wasn’t just their first time, it was their first time together. This was the start of their relationship as a mated pair. He would make this a perfect night for Kaeya.

His clothes dropped to the floor, and the whimper of need that spilled from Kaeya once Diluc was bare had his cock twitching. “Shh love.” He whispered, rubbing Kaeya’s thighs. “I’ll take good care of you. I know exactly what you need.”

Spreading Kaeya’s thighs, Diluc groaned. “Oh Kae.” He purred, licking his lips at the sight of Kaeya’s pussy, flushed and spread around melting ice. “You were so desperate for me weren’t you?”
Kaeya’s breath hitched and he shot Diluc a glare. “Sh-shut up! Just… do something!”

Diluc chuckled, lips quirked in a wide smirk. “Anything you want, love.” He promised, and gripped Kaeya’s thighs in a bruising grip. He pulled them up until they were slung over his shoulders. Perfectly positioned for Kaeya’s cunt to be inches from Diluc’s lips.

“Please.” Kaeya gasped, hips rolling toward Diluc desperately. His glare melted into an expression of pure need, and Diluc would meet every one of his needs happily. With an eager groan, Diluc’s teeth wrapped around the icicle Kaeya had thrust deep inside himself.

Kaeya gasped, whole body shuddering as Diluc slowly dragged the icicle out of him with his teeth. It slid out and Diluc spat it onto the floor beside the bed and narrowed his eyes at it. Let it melt. Kaeya would never need anything filling him other than Diluc from that night on.

But Diluc had to admit… it had opened Kaeya up nicely. Kaeya’s pussy gaped, hole twitching enticingly for something to fill him. He could make that hole gape even more. He knew he could. And how could he call himself Kaeya’s alpha if he didn’t give him everything his body wanted

So he dove in.

Kaeya tasted divine. Wet and dripping with slick so thick it coated Diluc’s tongue and flooded his tastebuds with sweetness. He knew with only one taste that he was forever addicted, and he fully planned to drink this nectar every single day from now on.

Kaeya seemed to agree, his voice sang out and his hips ground against Diluc, desperate for his tongue. One long lick between the wet folds of his cunt was enough for the omega to fall into addiction as well, Diluc could see it in Kaeya’s eyes, an all consuming hunger for more.

The omegas body opened up easily as Diluc’s tongue lapped up the slick, then thrust directly into the source of that sweet sweet nectar. Kaeya jolted and let out a cry. His hands flew up to grab and tug at Diluc’s hair, pulling him even closer.

“Wh-what are you doing!? Gods! It feels so good!” Kaeya sobbed. Diluc looked down from where he was lapping at Kaeya’s cunt and froze at the sight of tears springing up in the omegas eyes.

It was the most gorgeous sight Diluc had ever seen. Fat tears pooled in crystal blue and gold eyes. His cheeks stained a delicious red as they tracked wet trails down them. He looked so desperate and overwhelmed. A vision of perfection.

Diluc couldn’t hold back. He needed to make Kaeya cry even more. He dropped Kaeya’s thighs to his hips and spread them as far as Kaeya’s body could handle.
“No! Please!” Kaeya cried, tears sliding down his cheeks and creating an even more thrilling image. “Don’t stop!”

God he would make such a perfect slut. Already so desperate. Calling out so sweetly after only a little taste. Diluc grinned, knowing that all of Mondstat would kill for a chance with Kaeya. A chance to bed and breed him.

They would weep at Diluc’s feet once they knew he’d laid his claim. They would beg him for one night with his omega. One taste. And Diluc would laugh as they grovelled.

Kaeya was his. And he would make it abundantly clear that none but he could possibly hope to please Kaeya.

“Hush Kae.” He soothed, leaning in to kiss Kaeya’s cheek. Unable to resist, he lapped up a tear that fell from Kaeya’s eye and groaned as Kaeya’s breath hitched and even more tears fell. “Your pussy won’t be lonely for long. I’ll give you something even better now.”

“Yes!” Kaeya whimpered, reaching to scrabble at Diluc’s shoulders. “Gods please, I feel so empty. I need… I need you Diluc.”

Diluc grinned down at Kaeya and ran a hand down his body, lingering at his belly “Is that what you truly want, Kae?”

He pressed down, pushing against where he knew Kaeya’s womb lie, empty and aching to be filled. Kaeya shuddered at the touch and gnawed on his lip. “Tell me you want me and I will give you everything.”

“I-I…” Kaeya huffed, then turned a wet glare up at Diluc, but with a face full of tears it turned into more of a cute petulant pout. “You know what I want.” He accused, and Diluc grinned even wider.

“Yes. I know exactly what you want. But you have to say it.”
Kaeya groaned. But after mere seconds he crossed his ankles and tightened his legs around Diluc’s hips. He glowered up at Diluc with bright, hazy eyes and licked his lips.

“I want you to fuck me, Luc.” He said, rolling his hips into Dilucs lap. He placed a hand over Dilucs on his belly and whined “I want you here inside me. I need you! I need that fat cock of yours to fill me up until this awful emptiness goes away!”

Diluc’s heart pounded, and with a feral snarl he gave Kaeya exactly what he wanted. He snapped his hips forward and revelled in Kaeya’s scream of pleasure as he slammed his cock into the wet heat of his cunt.

Pleasure cut through Diluc like a flaming sword. He had to compose himself. His body shook with an overwhelming need to sink his teeth into Kaeya’s throat, to mate him as soon as he’d had a taste of the hot, tight heat that hungrily sucked in his cock.

He felt almost drunk on the feeling, and the sight of Kaeya, perfect Kaeya, with his head thrown back and screaming through an orgasm from the mere feeling of Dilucs cock entering him… it only made the heady feeling all the more potent.

“You’re mine now, Kaeya.” He growled, leaning down to lick a long stripe up his body, from his lush chest, up his neck to his jaw, tracing the perfect arch of Kaeyas body as he twitched and strained with an orgasm that had his pussy pulsing deliciously around Diluc.

“Mine.”

To be continued! Phew! Finally got this update done! I’ve really been struggling with life this month but hopefully things will be better from now on! (Also. Please note that Diluc was, in fact, jealous of that icicle.)

Kaeya's cunt was sopping wet and almost unbearably hot. Despite his attempts to satisfy himself with the icicle, he still squeezed around Diluc's cock so tightly. Diluc had to grip savagely at Kaeya's hips to stop himself coming immediately.

"Gods Kae." He groaned, hips grinding automatically to chase the overwhelming pleasure. "Your pussy is so fucking good. First time and you're cunt is already taking my cock like it was meant for it."

Kaeya whimpered and Diluc grinned "But it was, wasn't it? This pussy was made to be filled with my cock. Don't you agree love?"
Kaeya, still twitching from his orgasm, groaned brokenly. His eyes fluttered open and he looked up at Diluc in a daze.

The heat had well and truly taken him completely. And what a sight he made. As Diluc watched, Kaeya's tongue lolled out, drooling dumly as his instincts took over.  Trembling hands slid down his body to his belly. "So big... Diluc I'm so full~"

Diluc looked down, and his breath caught. Kaeya's belly bulged, just under his belly button where Diluc was buried deep inside him. Kaeya pressed his hand over the bulge and mewled, drool sliding down his chin as he lost himself to the feeling of being full for the first time.

He was mesmerising, and Diluc felt a deep, primal instinct burst forward and take over. His body moved on its own, cock dragging out of Kaeya before thrusting back inside with a harsh snap of his hips.

Kaeya screamed, his voice cracking with it, and Diluc couldn't stop after that. He pounded into Kaeya with a single purpose in mind: to breed his omega. To fill his womb full of cum and make it swell with it.

Kaeya met every thrust with a strangled cry. His hips rolled to meet them, and his pussy clenched and sucked Diluc deeper and deeper. They were both lost to their instincts, and Diluc vaguely wondered if he'd fallen into a rut.

He fucked into Kaeya brutally, and the omega loved every second. His moans filled the room, squeals and screams of Diluc's name spurring the Alpha on even more. And his body responded so beautifully, pussy drenched and squelching wettly with every thrust.

Fucking him got smoother as his pussy loosened just enough, shaping itself perfectly to Diluc's cock and sucking him in deeper and deeper, until with one particularly harsh thrust, the tip of Diluc's cock slammed against a barrier.

Kaeya gasped, almost biting his tongue as his whole body jolted pleasure. "W-what was that?"

A feral grin spread across Diluc's face, and he leaned down "That's your womb Kae." He whispered into Kaeya's ear, then leaned back to see his expression "Where I'm going to fuck you full of cum and breed you until you're fat with my children."

Kaeyas eyes went wide, and his cunt twitched, tightening around Diluc's cock and making him groan. "You'd like that, wouldn't you? Being bred full. Never being empty again." Kaeya mewled and nodded frantically.

"I'll give you everything you could ever want." Diluc promised as he ground his hips into Kaeya, cock smashed against his cervix, making the omega twitch and gasp. "I know what you need. From now on you'll always be full. Of my cum. Of my babies. Forever fat and satisfied."

With that, he pulled out and slammed back into Kaeya, ramming his cock against the omegas womb and making him scream out in pleasure. Soon Kaeya was begging, drooling for it, for more. Crying out to be filled and bred full of Diluc's babies.

It didn't take long for Diluc to reach his first orgasm. Kaeya had screamed through at least three since the first, and Diluc felt the intense heat building up in his gut so strongly he couldn't help but groan.

Surrounded by the tight heat of Kaeya's cunt, sucking at his cock so needily, Diluc's body was worked into a frenzie.
He gasped at the feeling of his cock swelling, his first knot forming at the base.

With each frantic thrust it swelled more, until finally it popped into Kaeya's hole with a wet squelch that had Kaeya' squealing, his body arching almost completely off the bed as Diluc pressed against his womb.

Incomprehensible babble spilled from the omegas lips as his cunt clenched around Diluc's cock desperately. And with a savage snarl Diluc came.

He filled Kaeya with burst after burst of hot, thick cum, shooting straight into the omegas ripe, fertile womb. Kaeya's whole body jerked as he came again, juices gushing from his cunt as Diluc continued to fill him.

Diluc gradually came up from his instinct driven daze, and was shocked at the amount he had filled Kaeya with. He'd never come that much in his life, but then again, he'd never knotted before either, and the way Kaeya's cunt squeezed and milked his cock it was no surprise.

Kaeya slumped into the mattress once Diluc finally stopped filling him. His tongue hung out loosely, and tear filled eyes were dazed and rolled back as his hand went back to cradling his swollen belly.

It was incredible. Diluc's cock twitched in arousal at the sight, still locked firmly inside Kaeya. Kaeya looked pregnant already, in the early stages with a bloated, round belly. Pride rose up in Diluc. He'd done that. He'd filled Kaeya to bursting.

They had a few more days of Kaeyas heat left, but Diluc was certain the omega was already pregnant. Filled with so much cum it was impossible it hadn't taken. He splayed a hand over the rise of Kaeyas belly and smiled down at him.

"Look at you. You're perfect. So full of me." It took half an hour for Diluc's knot to go down enough that he could pull out. Kaeya whined at the loss, and whined even more as cum poured out of him.

Diluc shushed him gently and wiped away his tears with promises to fill him again and again, as much as he needed.

And true to his word, as soon as Kaeya was empty and needy again, his heat spiking and body begging to be bred, Diluc was more than happy to fill him.
They fucked for hours, then days, exploring different positions and finding each other's sensitive spots.

In moments of lucidity between rounds, Diluc and Kaeya confessed their feelings for each other and marks appeared on their necks, binding them together. Then, finally, with Kaeya sated, filled and round with cum, his heat came to an end.

When Diluc woke, wrapped around Kaeya with his nose pressed to Kaeya's neck, he noticed immediately. The overly sweet smell of heat had faded from Kaeyas scent, and in its place was something else. Milky and warm, with hints if Dilucs own scent mingling in with Kaeyas.

A smile spread across Dilucs face and he pulled Kaeya closer. He'd done it. He reached around to stroke Kaeya's stomach as he took in the scent of pregnancy that clung to his mates skin. Finally, the family he'd promised to give Kaeya. And it would only grow from here.

Just as he'd predicted, Kaeya thrived with pregnancy. He glowed with happiness and life, showing off his mating mark to everyone, and when his belly got bigger he showed that off as well.

More than once Diluc had caught Kaeya stroking his belly and singing soft, foreign lullabies to their unborn child. Already a perfect mother.

When they fucked, Diluc worshipped the Omegas changing body. His wider hips, swelling breasts, fattening ass and thighs, and of course his gorgeous pregnant belly.

Kaeya loved it, the sway of his belly under him when Diluc took him from behind. How Diluc held it so securely while Kaeya bounced on his cock. And when his milk came in, Kaeya loved to watched Diluc lap up whatever milk he had let spill and fall onto his belly.

He was perfect. Diluc gave him everything. Did anything for him. Happily and proudly. While others may be considered whipped, too soft for their omegas, Diluc was simply considered lucky. Because they looked at Kaeya and saw how stunning and ethereal he was, and they understood.

Kaeya deserved this happiness, and just as Diluc had done anything to ensure it, he would do anything to preserve it.

Their first child came into the world, a beautiful baby girl that Kaeya doted on and Diluc spoiled. And once Kaeyas body had recovered, Diluc happily continued his endeavour to give Kaeya the family he deserved.
Kaeya was more than happy to be bred again.

THE END!!! Diluc and Kaeya live happily ever after with a swarm of children. Crepus is ecstatic and the most doting grandpa ever. Everyone is happy!

And for the final time- from the top!
