Kaeya can't really remember the last time he's seen Diluc leave his nest. It's been weeks, if not an entire month, in which Diluc has been going through the same motion every single day. Even if he isn't always there to actually see it with his own two eyes, he knows it does happen every day, if his clothes being scattered all over the room is anything to go by. He knows that Diluc must be going through a rough time, believing himself to be with child when that's not the case at all—it couldn't be the case. But there he is, watching him gather some shirts and blankets for the umpteenth time. He knows it's best not to disturb him, but at some point, he just cannot bring himself to leave Diluc in such a vulnerable state.
Except, it's not even up to him. Diluc's emotions have been all over the place, probably due to recent… events. It's a pity, really. Kaeya knows how devastated Diluc was when he lost their baby, even if it was during such an early stage. Diluc mourned their child for weeks. He would nest much more than usual then, and of course Kaeya was there, taking care of him. But it looks like Diluc's mind is playing tricks on him. It's clear Diluc is still grieving, but now he's certain he's conceived again. And that couldn't be. Though the doctors said he was not at risk, it was too soon for him to be with child again.
But of course, Kaeya couldn't refuse his demands. He was physically unable to refuse, so he did take him to an appointment. As expected, the doctor found nothing, but Diluc's state of mind was so fragile that he thought he was being lied to, so he's still convinced there truly is a child growing inside him.
"Of course it's negative! It's way too soon. I need to get the blood work done. It's more accurate, anyway."
Kaeya knew that the results would be the same, and truth be told, he feared how his mate's temper would change at being proved wrong once more, since there was absolutely no way the blood test would be positive, at least not for the time being. After many failed attempts at stopping the omega, he managed to dissuade him and actually wait to get another test done at home… Except the idea of it only made Diluc angrier, but at least it caused him to drop the subject altogether.
He knows Diluc must be going through a rather difficult time. He's spoken to Albedo and even if he hasn't actually taken Diluc with him (because he knows his illusion will be shattered in an instant) everything points to him going through a false pregnancy. Fake or not, he is ready to indulge his mate with whatever he needs, even if his hormones seem to be against him. It's not like he has any other choice, anyway.
"Can I come in, Luc?" He asked, knocking softly on the door. Normally, they would share a bed, but ever since Diluc started 'carrying', he found a room for him to nest in. Though Kaeya misses his partner and how things used to be, he can't help the sigh of relief that falls from his lips as soon as he basks in his omega's scent. If he's got anything to be grateful for about this entire ordeal, it's how much sweeter Diluc's scent has gotten. Yet, at the same time, the sweetness might just bring some rather unwanted attention, so of course, being the respectable alpha he is, he has to take care of his—definitely not—pregnant mate.
He's struggling as well, if he's being entirely honest. All he wants to do is fuck him stupid as he lets that delicious scent numb his senses, but Diluc insists on having no sex because he could harm 'the baby.' It's been driving him up a wall, but Kaeya is a patient man, so he limits himself to mere nuzzles against Diluc's scent glands, which seems to be very much appreciated.
It's not all bad, however. Kaeya melts at the sight of Diluc gently rubbing his belly and whispering sweet nothings to the imaginary baby. Looks like, in his mind, he did get to a very advanced stage. He's heard him on more than one occasion going on about how a wonderful father he would be, and maybe that does make him wish he could knock Diluc up once more. The sole thought of it is enough to make him hard, although he's ashamed to admit it.
After receiving confirmation, Kaeya carefully slid next to Diluc, immediately wrapping an arm around his waist to pull him closer, his broad chest pressed against his omega's back. He then placed a hand on Diluc's abdomen, caressing it gently, almost trying to feel a kick, or some movement. Something that may prove him wrong. Nothing. Luckily for him, Diluc seemed to melt into his touch. That was a first, at least during this week.
At some point, Diluc turned to face him, nuzzling into his chest for a while. Kaeya had missed this, these moments of tenderness between them. The comfortable silence was soon broken by his mate's voice, however.
"Fuck me," he demanded, out of the blue. Kaeya actually had to blink a few times, trying to process his words.
What?
Now, Diluc was not entirely bashful, but he wasn't this bold either. Must be the hormones, right?
"Diluc?"
"I said 'fuck me', Kaeya," he repeated, matter-of-factly, as those big red eyes came up to stare into Kaeya's. "Did you not hear me? What are you thinking about?"
"Yes, I mean— No, I heard you the first time. But, why—" The alpha was not given a chance to finish his sentence as he was quickly cut off by his mate.
"I think I've been pregnant for a while, and I'll need your help with that."
Kaeya simply blinked at him, clearly not understanding what was going on. "I… I don't get it, Luc."
Patience is a virtue. One that, for the past months, Diluc Ragnvindr has completely forgotten about.
"I need you to come in me, Kaeya. I read that semen can actually coax labour," he said, matter-of-factly. Because of course everyone knows that, right? "Come on… Haven't I put you through enough abstinence until now?"
Kaeya could simply not believe his ears. Diluc, his mate who was going through a very false pregnancy, wanted to be creampied just so that the so-called baby would be born.
"You… You do know it's not—"
"Are you refusing me?"
"No! Of course not, I just…" His voice faded out. Honestly, he couldn't say no. It's not that he can't live without sex, and of course he wouldn't have sex with his grieving mate, but as of late, Diluc had been rejecting him so much as cuddles when he was not in the mood for it—which was unfortunately quite common—, and the touch starvation was beginning to get to him. So he is afraid he might not be able to control his… urges.
"Are you sure about this?" He had to ask, but of course, Diluc was not having it. He yanked him closer by the loose collar of his shirt, and crashed his lips onto his, his hips immediately grinding against his.
Oh, gods. It's been so long. So, so long, he could even come undone just from this. How utterly pathetic. And Diluc seemed to use this to his advantage.
"You want more, don't you?" He tempted, his voice a sweet whisper in Kaeya's ear, though it still sent shivers down his spine. He was a weak man whenever it came to his beloved partner. He would give him the world if he could, and if it were up to him, he most definitely would've given Diluc all the children he desired.
"Yes… Yes, please."
Sensing Diluc's desperation, he immediately came closer to taste his lips once more, but it seemed he had other plans.
"Ah-ah," he taunted, pressing his index to Kaeya's lips. "I'm the one who knows how you can help me bring this child into the world, so you will let me do everything."
"Isn't the only requirement I cum in you?" He deadpanned. Diluc did not find it funny.
"Well, yes. But I intend to make the most of it, so no arguing with me," he stated, leaving no room for questions. Kaeya didn't really mind. He loved Diluc very much; if his mate said 'jump', he would ask 'how high', and this was no exception.
Diluc gave him a quick peck on the lips before laying down on his back, beckoning Kaeya closer.
"First, you need to stimulate my breasts. See? Like this," he instructed as he guided Kaeya's hands towards one of his nipples.
That was simple enough. It's not like Kaeya was not absolutely obsessed with his mate's chest. Before the pregnancy, he would enjoy suckling and teasing his cute nipples, and he knows Diluc definitely enjoyed the attention as well.
He carefully hovered over Diluc's stomach and began to press soft kisses all over his skin, pretending to be careful for the baby's sake. His kisses then began to trail upwards, towards his chest, noting just how pink Diluc's buds were. Absolutely adorable. A smirk drew on his lips as Diluc seemed to twitch beneath him, just from his breath alone. Perhaps he was feeling more sensitive than usual; all of his hormones and senses are going crazy, for a false pregnancy is still a hormonal imbalance after all.
If he didn't know any better, Kaeya would've definitely believed Diluc's claim about being pregnant was true, though not heavily so. He doesn't recall seeing him this… sensitive before. Just a small flick to his nipple, and Diluc was already whimpering with need. In fact, they did look a bit swollen. He dived in to take one of his nipples in his mouth, sucking on it as he twisted the other.
"Hah… leave some for the baby," he whined softly. Kaeya simply looked up at him, his ministrations becoming even more intense, if anything. Diluc's moans were loud enough for everyone to hear, but he suddenly stopped to speak. Or rather, tease him.
"I'm just making sure our child will grow to be a healthy one, Luc. Think of it as a quality assessment," he chuckled before diving back in, his eyes never leaving Diluc's face.
"Just like that, Kaeya… Harder, yes…" With each order, Kaeya complied. He had a goal in mind, after all. And if his expression was anything to go by, he was determined to fulfill it.
The shift in the omega's scent was subtle, but noticeable enough for Kaeya, the person with whom he had spent a great part of his life, and who was ready to create a new one with him—or rather, in him.
"Kaeya, wait!" Diluc cried out, but his alpha didn't listen. He knew what he had to do, so he kept sucking and pinching with desperation until a pleased hum fell from his lips… and not only that.
Diluc could only stare at the whitish liquid staining Kaeya's mouth in bewilderment. And if Kaeya was as confused as he was, he made no attempt to show it as he continued to drink from Diluc's chest. His eagerness did not go unnoticed as Diluc threaded his fingers through his hair in a soothing caress.
"Yep, our child will grow healthy and strong, Luc. It's delicious," he stated after a few more moments of torturing Diluc's nipples with his tongue while his hand wandered south. "Look at you, you're so hard already."
But before he could touch him properly, Diluc was already flipping them over to get on top of him, grinding his hips against his. Huh, so he really meant the whole 'I'll be in control tonight' thing. It's not like he minded; seeing Diluc so desperate was definitely doing things to him. So it was only natural he tried to help. The friction was delicious, but it was clearly nowhere near enough for Diluc, so why not provide him with some assistance?
Well, it didn't go too appreciated.
"Did I say you could move?" He hissed. Kaeya stopped immediately, though he did give him a confused look. Seriously, his patience was being tested here… But he would do anything to make Diluc happy, he thought. If Diluc was enjoying himself, then that's what mattered the most to him, so he willingly obliged and allowed Diluc to take the lead. There was something about Diluc's—slightly—annoyed expression that really got him going. Kaeya swore he could get burnt by the fire in Diluc's eyes, and he was willing to try.
His state of admiration for his mate's beauty didn't last long, though, as Diluc soon jerked him a few times before sinking down on him without warning. Kaeya could only whimper pathetically at the feeling of Diluc's warmth around him, breathing becoming a conscious chore shortly after. He tried to move—again—, but Diluc pinned him down with his body weight to stop him from doing so.
"Luc, please…" He begged softly. This was torture. Absolute torture. Being buried deep inside Diluc, that delicious feeling wrapping all around him after so long and not being able to move or do anything about it… It was enough to drive him wild with need.
"What if you hurt our child?"
"I'll be gentle! I promise, love. Don't you trust me?"
"Mhm, will you?" Even if he was questioning him, Diluc began to move his hips in a perfect figure. It was clear how much he was holding back, convinced he could hurt the life growing inside him if he was not careful enough.
"Look at you, controlling yourself," he teased Kaeya. He knew, after all, just how much power he held over him. Kaeya tried to thrust again, but only managed to get a chuckle from Diluc, so he finally decided against it and allowed his partner to take charge.
"Luc, you feel too good. Please…" he cried out, and, at last, Diluc acquiesced.
"Come on, didn't you want to fuck me properly?" Kaeya immediately took the hint, and so his hips began to rock into his mate. He couldn't help the low groan that escaped him. The pleasure was overwhelming; he couldn't remember a single time he had felt this good. Maybe abstinence had really gotten the best of him.
"Am I being good, Diluc?" He panted, his voice hoarse. He was trying his best to please his insatiable mate, and it was clear he was doing a great job at it. But Kaeya still wished to be praised, to have his efforts be acknowledged by Diluc. "See? I… I'm not hurting the baby!" He whined as his hips bucked into Diluc in a sloppy rhythm. Kaeya felt so pitiful. He swore he could cum just from being inside Diluc, and he did. He didn't last long, at all. Diluc was just way too good at riding him, but even as he spilled load after load into him, his partner didn't stop moving.
"I'm sorry! I… I just…" His voice was a hoarse whimper as he tried to get a hold of himself.
"Don't worry, Kae. Keep going," he panted, though his voice lost the commanding tone.
Kaeya was still trying to recover his brains after such a strong orgasm, but as soon as Diluc's words processed in his mind, he began to move his hips again, though in a much more composed manner now. He couldn't let Diluc see him in such a pathetic state. His hands went on to grab onto Diluc's hips as his own moved into him, setting a constant pace that contrasted much with his desperate movements from earlier.
"Luc, you'd be such a beautiful mommy… I bet our child will take after you. Just imagine it, a mini you running around the house, with your bright eyes and red hair." Each of his words was punctuated by a sharp thrust right into Diluc's prostate, causing him to squirm on top of him as his own cock leaked onto his abdomen.
"Kaeya… C-careful. The—ah! The baby! Too deep…" He whined. Oh, how gentle of him. Kaeya couldn't help but think of how sweet of a mother Diluc would be. He'd love to see his chest swollen with milk, his lean body with slightly wider hips as he's carrying a round belly, full with life. Life that they created, life that he put in him. Maybe if he tries hard enough, he can actually get Diluc pregnant, and make sure it stays in order to fulfil his beloved partner's wish this time.
He couldn't help it; that mental image really did things to him, and soon enough, he was moving his hips in tandem with Diluc, thrusting deep into him. Screw the baby, he would fuck a new one into Diluc. He would try and try again until he was sure he had left his mark in his partner's womb.
His mate's moans became even louder, head thrown back in pure pleasure. "Kaeya! Too rough!"
"But I'm just trying to help the baby be born, Luc. Aren't I making you feel good, too? You like this, right, Luc?" Diluc was left unable to answer as all he could do was moan and whimper while his hands settled on his belly, gently pressing down on it as if he could shield the baby from Kaeya's rough movements.
The sounds filling the room were absolutely lewd, between Diluc's moans and the wet sound of skin against skin as Kaeya fucked his cum into Diluc's hole with renewed strength.
"This is all for the baby's sake, but surely you missed this as much as I did. Fuck, you feel amazing, love. Your scent is so sweet…"
"The baby! Kaeya, you're going to…Mgh!" Diluc cried out, his words stumbling in between moans. He had kept his composure before, making sure he was the one in control while Kaeya pleasured him. But now, he was such a sight to behold, with hazy red eyes that tried their best to focus on his alpha.
"Luc, I'm gonna cum! Please, Luc!" Even if he had wanted to wait for an answer, Kaeya couldn't take it and came inside him for a second time.
"So pretty," he cooed with genuine admiration as he caressed Diluc's swollen belly. He really had pumped a good amount into him. He did not want to think about what would've happened had Diluc actually been pregnant. But he looked so happy, Kaeya didn't have it in him to break the news.
"Should I keep going, love?"
Even though Diluc looked like his brains had been fucked out (which was true), he scoffed. "Of course you should… It's enough when I say it's enough. And don't try any funny business," he threatened as he began to move his hips once more, at a much slower rhythm. It was clear the exertion was becoming too much for him, but that he would keep going until the damn baby was crowning. That meant Kaeya had the entire night to make up for lost time. But being the considerate alpha he was, he held onto Diluc's hips to stop him and gently lifted him off his body to settle him back on the bed, on his stomach this time.
Kaeya couldn't help but admire the beautiful sight before him: Diluc's hole, twitching. Already painted in white but eager for more. And how could he say no? If Diluc wanted him to cum a hundred times that night, he would. He could die in the process, but he'd be a happy man doing so. He could deal with the appointments and all that hassle later. Right now, all he wanted to do was make his mate feel good… and maybe actually fuck a new life into him.
