Summary:

Maybe he should have come clean about being an omega when he joined ABIS. Maybe then he wouldn’t have been here, a thin sheen of sweat breaking out on his arms and forehead, pleasant haze fading into something needier while Date worked on the paperwork they were here to finish.

Upon later reflection, Ryuki remembered that Pewter had told him his heat would be a week early.


(Late submission) RyuDate Week 2023 Day 4 - Fever Dream. Please see content warnings and verse details in notes.

Notes:

ABO Verse Notes - Generally, if you are familiar with Omegaverse, all relevant info should be able to be picked up in context.

Click to show notes on things that vary in ABO fic:
  • Secondary gender isn't treated as a class or formally used to exclude people from professions. Social stigmas exist but the main motivator for Ryuki hiding his gender is his own thought process about being a hero. It is possible to completely suppress scent/pheromones in daily life.
  • Omegas have varied genital presentation, Ryuki has a vagina.
  • Both alphas and omegas have fangs that appear during heat/rut or when intending to mate. Ruts/heats aren't triggered by each other.

Very mild dubious consent CW in that pheromones are the instigator for acting on existing (undiscussed) feelings.

Click to show additional spoiler/specific details about the consent CW:

Ryuki and Date have sex that is initiated while Ryuki doesn't know he's going into heat and Date makes some effort to say that they shouldn't. Ryuki experiences some distress during due to thinking poorly of himself, but is comforted. Ryuki experiences brief discomfort from over stimulation.

Work Text:

It was raining today, which should’ve tempered the summer heat, but Ryuki found himself groggy instead of refreshed. The moisture in the air had weighed heavy on his skin all day, even in the halls of HQ, and any exposure to it instantly erased the hours he’d spent cooling down in the air conditioned and subterranean ABIS office.

He had already been fatigued in the morning, so by the time the day wrapped up Ryuki was more than ready to get home and shrug off his dress shirt and slacks. Then it would be nothing but lounging in front of a fan, attempting to read a book Amame had leant him, and maybe getting into bed early for once.

But then Date had come to mope at his desk about how Boss was so, so unfairly insisting that he stay late to finish the past due reports spilling out of his inbox. 

…So, Ryuki forgot his plans in favor of some paperwork he definitely couldn’t put off and followed Date to one of the coworking spaces upstairs in the general HQ offices.

There was always something reassuring about Date’s presence. It was magnified, in Ryuki’s mind, by the fact that there were no secondary genders at play at the office. Ryuki loved that even without the chemical comfort of Date’s alpha scent, he trusted Date to have his back as a fellow agent. The advice Date gave him wasn’t skewed by overprotectiveness brought on by Ryuki’s presentation but the things he really thought about Ryuki’s skills and potential. 

ABIS had a strict policy requiring all agents to wear scent neutralizers to prevent any potential interference with interrogations and psyncs. Like all ABIS rules, Ryuki was sure it had been bent once or a dozen times – but never by him. A beta’s mild pheromones had no chance of influencing suspects, as Date and both Mizukis pointed out on occasion. They would whine that he was so lucky to have wiggle room, would pout when Ryuki insisted that he had no intention of slacking due to his status. 

Really, Tama huffed each time, They have no idea how much you spend on patches! Just once – I know I can’t – but it would feel great to smack them with how insensitive they’ve been! Can you imagine? The look on Date’s face when he realizes…

Tama went on and Ryuki finished the sentence himself. ‘How hard you’ve been working,’ generally took a back seat to, ‘That this means Ryuki’s an omega whose scent might be amazing and make him super datable.’ Or, ‘That Ryuki has been lying for years and clumsily flirted with him under false pretenses, which Date decides is a deep personal betrayal.’ 

But that one was only on bad days. 

In fact, he was in the midst of considering potential paths for option two when Date’s very real voice snapped him out of his reverie.

“Ryuki, hey,” Date had an eyebrow raised as he looked up from his laptop. They were set up across from each other at a conference table. Maybe sitting where his productivity (or lack thereof) was in plain view hadn’t been the best choice when Ryuki had spent all day distracted. “Are you feeling okay?”

“Hm?” Ryuki tapped his pen against the knuckles of his free hand. Hopefully it read as concentrated rather than idle. “Of course. I’m a bit tired, but I can keep working!”

Blame it on the weather, but Date’s concern stirred more affection in him than usual. Now if they could just both be lazily wiling away the evening in Ryuki’s apartment, that would be perfect. The thought enticed Ryuki enough to imagine that Date’s gaze lingered just a moment too long.

“Never just do the bare minimum, do you.”

Ryuki shrugged and made a small comment about Date being the same before they both returned to their work. That morsel of affection kept him focused for at least another half hour. The office was always quiet by the time ABIS finished work, but today it seemed exaggerated. It would be so easy to fold his arms on the table and slump down for a nap.

“Are you cold?”

Ryuki opened his mouth to deny it but couldn’t. He’d been bothered by the humidity all day, and he was wearing layers like usual, but still, something was missing. At the realization, a chill ran through him. 

He nodded, “I guess so. The AC in here is a bit much for me.”

“Then here,” Date had shrugged off his coat and slid it across the table. 

“Oh, no Mr. Date, that’s okay.” But as he spoke, his hands rebelled, grabbing and pulling the coat into his lap. Some of his discomfort was sated just by touching the warm fabric and he knew having it on would be better, but his eyes flicked back up to Date.

“It’s fine, I’m too warm anyways. I wouldn’t offer if it wasn’t okay.”

When Date gave him a little smile and turned back to his laptop, Ryuki pulled the coat on quickly. So nice… Mr. Date is always so nice. His mind already drifted to Date far too often, even more so today, but now – wrapped up in Date’s warmth and scent and thoughtfulness – it was everything he could do to just look at his paperwork.

Something was definitely off. It was probably him, Ryuki knew that, but Date’s behavior seemed different too. He had only complained about Boss’s “obvious” favoritism towards the Mizukis once and hadn’t procrastinated by asking inane questions about Ryuki’s work at all.

Instead, it almost felt like Date was… it was silly, he knew it was, but Ryuki kept thinking that Date was looking at him. 

Usually he would glance up to check without hesitation, but today he just did his best to ignore it. The idea of Date watching him, because Ryuki had chosen to hang around, because Date had noticed that, because he enjoyed when Ryuki was here… Each time he felt Date’s eyes on him, the uncomfortable itch under his skin intensified. The coat – the coat had helped, but he needed…needed…

“Hey, where’s Tama?”

Ryuki blinked, trying and failing to banish the fuzzy feeling from his mind. Shit, how long had it been since Date had noticed he was cold? He had definitely spaced out for more than a few minutes, but without Tama he couldn’t be sure just how much longer. 

“Oh, she’s with Pewter.”

She was due for quarterly maintenance. All psyncers and AIBalls were on a set schedule to allow time for heats or ruts, for those who had them. AIBalls helped with hormonal regulation and had potential to guide agents through their cycles, but Pewter simply wasn’t confident that the current physical structure could be maintained through all the irregularities that came with them. Pewter knew Ryuki’s (and everyone else’s) actual secondary gender and exercised appropriate caution when it came to Tama’s well being.

Today was weird, though – that’s right, that had been the other reason things seemed strange – as Pewter had shifted the schedule up a week. He had informed Ryuki when he dropped Tama off before his last heat, but that was months ago, and when Tama reminded him about the change a few days ago he’d been surprised. That meant he would need to just leave her docked when his heat actually came, but he dreaded those days enough that any additional responsibilities made him preemptively anxious.

Tama had chided him when he mentioned it this morning. Pewter had frowned and insisted that Ryuki take some informative flier with all sorts of reminders that his supressants and birth control had been adjusted with the schedule for sustained efficacy - not that Ryuki cared what that meant at eight in the morning. Ryuki had brushed off his request for detailed feedback about his pre and post heat mood, slightly irked by Pewter’s attitude. Like he hadn’t been doing this for years.

“Then how’re you planning to get home?” Date’s voice cut through his thoughts easily. If he hadn’t been feeling so off-kilter, Ryuki might have been able to stop a small smile from springing up at the third (third!) instance of Date worrying for him. “You’re not feeling well, right? Can you usually drive like this?”

“What do you mean? I told you, I’m just tired…” The excuse wasn’t working twice. He was definitely feeling more dazed than he had been when they first arrived, though. If Date was concerned, Ryuki figured he should probably try and fix it. “Maybe I should get some coffee or something, though.”

“I’ll get you some.” 

Date was gone before Ryuki could argue, saying something about wanting to stretch his legs.

Not that Ryuki really had it in him to fight Date’s declaration regardless. It was far easier to slip back into daydreaming and wait for Date to come back.

Even though he was starting to feel too warm, that was far preferable to parting with Date’s coat. It was so rare that he could indulge in his scent like this, after all. Date was professional, despite his complaints, almost always wearing a pheromone neutral cologne at work and sometimes scent patches too. But outside of work, without that rule, he was more casual, as Ryuki learned the first time they’d met up at Marble a couple years ago, shortly after he had joined ABIS.

If he hadn’t been so used to ignoring scents from his time at the academy, Ryuki was sure he would have completely blown his cover when first faced with Date’s. When he slid onto the barstool beside him, Ryuki tripped over a greeting and rushed to get tipsy enough that he could stop being hyper aware of the warm, familiar buzz that Date’s pheromones gave him. 

Even as they spent more time outside of work together over the years, the feeling didn’t fade.

The fact that Ryuki couldn’t even scent Date or any of ABIS for comfort after a close call at work, or enjoy small items from his coworkers as nesting material during his heat meant that he rarely got the chance to notice Date’s scent even in passing. 

Those things, even just intimate friendly things, would be enough, if he could be honest about being an omega. He didn’t need Date to really want him, he just needed something to curb the sting of keeping his omega side isolated for years. He hadn’t had friends that close since high school, and spent the painful, unfulfilling few days locked in and alone. 

Maybe he should have come clean when he joined ABIS. Maybe then he wouldn’t have been here, a thin sheen of sweat breaking out on his arms and forehead, pleasant haze fading into something needier. 

When Date returned a few minutes later, Ryuki had done up every button on the coat and moved to settle more comfortably on the room’s only couch. It was not particularly soft, intended for short breaks rather than any sort of relaxation, but the synthetic fabric was cool against Ryuki’s skin. 

He had kicked off his shoes and was sitting against an arm of the couch with his legs pulled to his chest. Date’s coat was big enough that Ryuki could easily hide the bottom of his face behind the high collar with it fully buttoned. Being so wrapped up made him feel somehow safer, and was almost like hugging Date (a thought he might’ve shaken his head to clear it if this position wasn’t so damn comfortable). It didn’t quite ease the discomfort that had been itching at him for the past few hours, but it was definitely better. 

Of course, he was still… well, still prepared to get work done. The stack of papers was in front of him, untouched. How could he be blamed, really, when every part of him just wanted to get cozier and burrow further into the couch?

Date stopped a few feet away and cocked an eyebrow at Ryuki’s new setup.

“Whatcha doing?”

“Working.”

It was obvious that Date didn’t find it convincing, but he didn’t push. Instead, he extended his hand to offer a colorful bottle. Ryuki straightened to reach for it and paused.

“This isn’t coffee.”

“No, it’s not.” Date ignored Ryuki’s pout. “But you’re always saying you need to stop drinking caffeine at night, so take it.”

Ryuki wanted to insist, clinging to the idea of proving that he could drive home. But his will softened as he looked at the bottle, still in Date’s hand as he waited. He wanted coffee, but Date had picked this out for him… Alpha brought it for us, his mind supplied, alpha’s taking care of us

“Thank you,” he mumbled, giving in and accepting the juice. Date just nodded before turning and going back to the desk.

He wasn’t sure how many minutes ticked by with Date continuing to pick through case work, keyboard clicking softly, and Ryuki sipping his drink, spacing out, paperwork entirely forgotten. Date had been right to choose juice after all. Ryuki wasn’t feeling nearly as tired but was now just… unsettled, uncomfortable. Date’s coat was heavy and too warm, but he hated the thought of taking it off. It must be past seven, then, when maintenance left the building and shut off the air conditioning. 

For the first time since they had gone back to ‘working’, Ryuki let himself look at Date. 

He was focused, staring at the screen, fingers unmoving over the keys as he concentrated. Of course Ryuki’s distraction wasn’t affecting him, Date was always so dedicated to getting things done. Other people didn’t get it, but Ryuki knew. The amount of things Boss nagged him for, the amount of busy work he blew off couldn’t compare to the actual, important good that Date did when working a case. And see, he got it done eventually!

Right now, though, Ryuki wished Date wasn’t so interested in finishing his task. It was okay, he reassured himself, that could be fixed, when Date was finished, maybe they could stay a little longer, chat just a bit more. Maybe it wouldn’t even hurt to let Date drive him home. If he was so worried, Ryuki wasn’t above enjoying when Date took care of him. 

Such a good alpha…

As if tuned into Ryuki’s thoughts, Date’s gaze snapped to meet his. Usually, he’d call this sort of thing a coincidence, would smile and look away (there was no point pretending he hadn’t been looking and he wasn’t ashamed of admiring Date, wouldn’t fool anyone by scrambling to busy himself with something else). But this time the idea of Date seeing right through him stuck, hard, and sent excitement straight to his core.

Date didn’t look away either.

Even the air in his lungs felt hotter with Date’s eyes on him. Contradictory urges wanted to hide, to beckon Date closer, to shed the coat because he wanted as little between himself and the alpha as possible, to take it off because it was heavy and would make fleeing harder, to whine and open himself up until Date got the message –

Too much, too much – Ryuki squirmed, letting the collar of the coat cover his nose and mouth, and sucked in a shaky breath. Not for the first time that evening, he scratched at his neck anxiously. Date stood, strode over (too fast, oh god, closer and closer and bigger and safe and good –), and pressed his hand to Ryuki’s forehead with no warning.

“Shit, you’re burning up.” Date’s brow furrowed and he made to pull his hand back, which was no good at all. Not that his skin was cold, but touching helped and he couldn’t just take that away so fast, Ryuki would – would – well, he didn’t want to find out. Date’s eyes widened when Ryuki latched onto his sleeve with both hands. Date sized him up for a moment, then two, before taking a small step backwards and covering his mouth and nose with his free hand. “You… you need to go home, Ryuki.”

This time, Date’s words weren’t enough to halt his thoughts, couldn’t break his focus, and Ryuki took the chance to look him over instead. Seeing Date without his coat was already such a treat, but being this close, late enough in the day that his neutralizing cologne had faded, was something else entirely. His shirt fit so well, showing off his solid and surprisingly strong body just enough for Ryuki to imagine being completely engulfed by him. 

Ah, there, that’s it. At last, the thought of what he was missing had taken solid, understandable form, and his omega instincts washed over him with satisfaction at the acknowledgement. That’s what he needed, not a coat or juice or a nap, but Date over and around and inside and perfect.

His temperature was rising still, making his breaths come quicker. Ryuki kept hold of Date’s arm to steady himself and rise from the couch, only needing to keep his balance long enough to shuffle forward a half step and bury his face in the juncture of Date’s neck and shoulder. 

Date’s startled noise and the discomfort of wet fabric rubbing between Ryuki’s legs barely registered because finally, finally he could breathe in Date’s scent so easily and so close and so perfect. Desire exploded inside him, every inch of skin on fire as his fulfillment rapidly shifted into need for more.

“Ryuki?”

Oh, he hadn’t realized how much he was missing Date’s voice. He gave a small trill into the fabric of his shirt and nosed at the hem of its high neck. Ryuki needed to taste him, needed that out of the way –

“Hey, hey, watch it.” 

Date had to pull hard to take back his hand, using both to push at Ryuki’s chest, forcing him back when he moved to pull Date’s collar down. Frustrated, Ryuki bared his teeth and tried to press forward again for more skin to skin contact. 

“Ryuki,” Date started again, searching Ryuki’s expression and tightening his grip on his upper arms to keep him in place, “C’mon, still with me?”

Ryuki nodded. He was here and that was the problem, he was here and Date wasn’t doing anything, why wasn’t he doing anything? 

“Say something.”

“Alpha…”

“Shit,” Date shifted underneath him and took a shaky breath. The hands wrapped around Ryuki’s arms strengthened their hold. “Not that. Don’t tell me you’re already so out of it that you don’t know who –”

“Date, Mr. Date – please, I know, I promise.” The words were tumbling out of Ryuki’s mouth as soon as he understood Date’s meaning. Impatience and excitement were vying for control, with the need to prove whatever Date wanted winning out over his frustration. 

“Okay,” Date loosened his hold, exhaling heavily and practically dropping Ryuki back to his chest.

Ryuki slid his arms around Date’s waist and nuzzled into him. His answer was good, he was good. Relief rushed through him when Date didn’t resist this time, instead rubbing at Ryuki’s lower back. He was making an effort to be gentle, but his thumbs dug in harshly when Ryuki licked at his scent glands.

“I can, if you just put your patches back on — or fuck, I can do it, I have extra — then, I’ll drive you –” 

He had never heard Date’s voice like that, so much softer than usual, strained, like he was holding back. Distantly, Ryuki wondered when he had even taken his scent blocking patches off. His inner omega didn’t care, but swelled with pride – Date was so good, trying so hard to do the right thing, just like Ryuki knew he would, he always did, behind all the jokes – he’d picked such an amazing mate.

Date stayed stiff even as Ryuki rolled his hips forward. He whined, continuing to lick along Date’s jaw and scenting him. It only took a few more moments, a few more too-tight grabs at his hips, before Date openly groaned when Ryuki bit at his earlobe and ducked, giving into the urge to scent him too. 

All Ryuki could do was gasp and throw his head back the moment Date’s nose met his skin. It had been years since he’d been touched there, so long that he only really remembered the idea of a connection, enough to want it but not nearly enough to anticipate how it felt. And it felt… it felt…

Relief completely overtook him as Date’s pheromones intensified. Somehow he’d missed Date undoing the top few buttons of Ryuki’s borrowed coat to expose his neck, too focused on wobbling in his hold, appreciating every rub along his jaw that promised safe and claimed and taken care of. It would take days for it to wear off, which he should… should, something told him, he should worry about that, but… Even though it would make keeping his cover near impossible, it would be Date’s alpha scent on him and that wasn’t something he wanted to reject.

Wait — his cover? 

Teeth grazed his throat and had Ryuki keening. There were too many things he needed right then – hours ago, tomorrow, last week, Date’s hands and teeth and bite and scent and knot – his mind couldn’t keep up or be worried about whatever part of him wouldn’t want Date’s scent all over. All Date had to do was nudge him and Ryuki fell back, looking up from the couch in a daze. 

Date was perfect. Tall and beautiful and always looking out for him, always safe, especially now, especially smiling and looking Ryuki over like he’d never seen anything better. Which didn’t seem possible, given how Ryuki was barely keeping upright on the couch and failing to breathe properly. 

He shifted under Date’s gaze and undid the last few buttons of the coat, shrugging it off. Being free of it was a relief and a loss. He needed Date to fill in the gaps, to pull the heat from his skin until he could do something other than rest his head on the back of the couch and part his legs.

Date sucked in a breath and just stared for what felt like hours. Being impatient was no good, though, Ryuki needed to wait, needed to push down the urge to touch himself. Date’s eyes wandered from his flushed face and heaving chest to the noticeable wetness seeping through his pants. Ryuki followed his gaze and blinked. He hadn’t even noticed the slick pooling between his legs, too distracted by the heat everywhere else, but now that Date’s attention was on him, he was fully aware of just how wet he’d gotten and it hurt.

Sitting still was painfully uncomfortable, moreso now that Date was so close. Ryuki could feel himself slicking further. He was so empty, so needy, too much. He just wanted to grab and pull him down or jump up and wrap himself around Date tight enough to rut against him. 

What is taking him so long? Ryuki shifted on the sofa, barely resisting the urge to close his legs and get some friction – after all, if Date didn’t want to…

Oh, maybe that was it.

Ryuki had lied to him, after all, saying he was a beta for so long. Maybe that was too big of a betrayal, maybe alpha hated him, maybe… Was it possible Date still didn’t believe he was an omega? No, Date was smart, but even so... Showing him couldn’t hurt, right? Present, his brain supplied, clicking Ryuki’s disjointed thoughts into something defined and doable.

With a final glance up to confirm that Date still hadn’t moved (still too far away, still just staring, not touching, stupid), Ryuki lifted his hips to wiggle his pants and underwear down at the same time, struggling for a moment to untangle them from his legs. By the time he tossed them aside with a huff, he was truly frustrated. At least the couch was cooler than his skin, but it wasn’t soft enough. Ryuki sat up straighter through sheer force of will and tried to ignore the shakiness in his limbs, Can’t believe he’s making me wait and do this myself

When he looked at Date again, though, his distaste vanished. Date had finally moved closer, shins a few inches from the couch cushion as he stood between Ryuki’s legs. 

The smile Ryuki loved so much was back, as was the focused look usually reserved for solved cases or magazines or – or he couldn’t remember what else, but it didn’t matter because now it was for him. He was supposed to turn over, finish presenting, but Date’s gaze had him pinned half-naked and with no will to finish flipping onto his stomach.

Date extended a hand. Before he could find out his intent, Ryuki had taken it in both of his hands and brought it to cup his face and touch his scent glands again. Date took the hint, leaning over to thumb the sensitive, swollen spot. Ryuki let his eyes flutter shut.

“M-Mr. Date…”

“There you go, that’s right.” Ryuki breathed in Date’s scent again, worries about being unwanted fading fast. Date let out a wave of possessive, cooling pheromones and Ryuki gave a receptive hum. Smiling softly, Date slid his hand to grip Ryuki’s chin. “I know what you need. I’ll give it to you, baby, don’t worry.”

Ryuki was nodding hard enough to make himself dizzy before Date was even finished talking. 

Date nudged his legs further apart before kneeling and sucking in another breath. “Holy shit.” Date sputtered for a moment, smooth talking halted by the sight of Ryuki spread open for him. “This is – fuck, Ryuki, you’re –” Date seemed to reach without thinking, dragging two fingers over his slit and staring at how wet they were when he pulled them away. Ryuki’s whole body shuddered when Date finally touched him only to feel even worse off than before when he quickly withdrew his hand. 

“Please, Mr. Date, I – I need…”

He was panting openly now, face scrunched up and thighs shaking as he tensed and tensed and tensed to try and relieve something in him until Date would take pity and touch him properly.

Sure, he’d spent plenty of nights imagining Date moving slowly, teasing the tension out of every part of his body, but now was not the time to be – Ryuki opened his eyes at the sudden feeling of strong hands under his thighs. Date pulled him forward so his hips were at the edge of the couch. 

Oh, okay.

Ryuki’s desperation was easily redirected at the realization that he was, in fact, possibly not being teased. He slid down the back of the couch and had to hold his head up to see Date’s face. The last thing Ryuki saw was that grin and then he was throwing his head back against the cushion as Date started lapping up the slick dripping down his thighs. 

“Yes, yes yes, ah!” His entire body arched up, frantically searching for more.

Though his enthusiasm made it clear that he would have been content to focus solely on drinking every drop Ryuki gave for hours, Date gave in to Ryuki’s needs quickly. Strong hands held his thighs apart as Date started to lick at his cunt properly.

Ryuki cried out and all the muscles in his legs clenched. At the angle Date had him, all it did was cause his ankles to knock together uselessly behind Date’s head. Date laved his tongue over his folds, working it between them before licking a stripe up to Ryuki’s swollen clit. His frantic whining continued as Date lavished him with sloppy attention. Shamelessly, he rolled his hips to urge Date on. 

It wasn’t enough, wasn’t going to abate the heat inside him, couldn’t fill him the way he needed, but that didn’t mean Ryuki wasn’t writhing in no time, so close to coming when Date pulled away to catch his breath.

Every second that Date’s mouth wasn’t on him hurt, but before Ryuki could complain Date’s tongue was back and actually inside him. Ryuki’s hands flew to tangle in Date’s hair as his back arched and a desperate kind of sound he’d never made before escaped.

Of course, of course he’s amazing at this too. 

One of Date’s fingers easily slid in to join his tongue and scratched the surface of Ryuki’s need for the first time. He gasped as Date worked it in to the knuckle, feeling himself clench hard around it and oh, finally he wasn’t so completely, painfully empty. 

After a tentative (way too slow) thrust, their eyes met and Ryuki let out a high-pitched whine, nodding and bucking his hips. Date obliged, picking up the pace and adding another finger when Ryuki slicked further at the stimulation. No longer held in place, Ryuki’s legs tensed in high-strung pleasure, thighs shaking and boxing in Date’s head.

“Good?”

The sight of Date on his knees for him, cheeks and lips a delicious shade of red, and his mouth wet with Ryuki’s slick was almost enough to push him over the edge all on its own. Possessiveness flared up in his chest, too. Having an alpha like this, especially an alpha he’d been so enticed by since the day they met, submitting and interested in doing exactly what Ryuki wanted – it was an entirely new feeling, sure, but it was so pleasing to his omega that his breath caught in his throat.

“Y-yes! More, ’s good, more, please.”

Date grinned and oh, fuck, his fangs were poking out. 

Mate, mate, mate, his mind was overrun by renewed heat. Take bite, take alpha, claim him. Ryuki let out a low moan and his legs relaxed to open and accept Date more easily.

Until now, Date’s eagerness to keep his mouth occupied kept him from getting a real rhythm going, but Ryuki’s words and submission refocused him. He set a steady, intense pace with his fingers, curling them inside to seek out the best spots. Each thrust felt better than the last and promised more, promised filling, breeding, and Ryuki needed it, needed to tell Date, but forming words on his own seemed impossible. 

But Date knew him, even this part of himself, somehow, adding a third finger and pressing kisses to the inside of Ryuki’s thighs. He didn’t hesitate to work back up to his previous pace. Transfixed, Date’s lips were parted as he watched his fingers slide in and out of Ryuki’s pussy. Ryuki couldn’t see it, but the slick noises were enough for him to imagine just how eager and open he was becoming. 

“Fuck, look at you.” All Ryuki could manage was a whine. “So good, omega, so fucking perfect. Can’t believe you – you – that I’ve got you like this.” Date brought his other hand to rub at Ryuki’s clit and he actually yelped from the heightened sensitivity. “There you go, yeah. Go on, you’re gonna come all over my fingers, aren’t you?”

Ryuki desperately rutted up against Date’s hands as way of affirmation before his whole body tensed and his mind went blank. The pleasure and satisfaction lasted just long enough for him to feel a lapse in his heat, a tiny reprieve before he was groaning and clutching at his abdomen.

Empty.

A bit of the ache was eased by the alpha pheromones still surrounding him while Date claimed the excess slick on his thighs. Date sat and licked his lips before moaning openly when he tasted more of Ryuki’s slick there.

“You taste so damn good.” The idea that alphas got some sort of high from omega slick was one Ryuki always figured was made up whole-cloth for porn. But this was Date after all, and Ryuki would be hard-pressed to describe the look in Date’s eyes as sober while he cleaned the fingers he’d had inside him moments before. “Can’t believe you kept this from me so long.”

Ryuki’s chest was wracked with a gasp-turned-sob as Date pressed his fingers back to his over sensitive slit. Suddenly, this was too vulnerable and Date’s words brought back all his anxiety about staying disguised as a beta. It was just like Date said, he’d been so stupid, to lie, to pretend, to hoard every kindness Date showed him and pore over them again and again while locked up in his apartment during his heats, to take what Date hadn’t even known he’d been giving and use it like that.

“‘m sorry, I’m sorry –” 

That’s why Date hadn’t been eager to mate him from the start — he didn’t want to. His inner omega flared up at the rejection and his insides ached worse for it, even as Date worked him with surprising gentleness. Usually it would be fine (he had spent too many heats to count chasing satisfaction with toys and barely distinguishing one orgasm from another), aided by slick and his addled brain, but the thought of failing to be good enough gave the touches a dull sting.

Date’s fingers pushed back into him (not enough not enough not enough) as tears welled up in Ryuki’s eyes.

“Shouldn’t, ahh, shouldn’t have lied, ‘m – I can’t –” He screwed his eyes shut but couldn’t escape how good it felt, back arching to take him deeper – Even though he didn’t deserve it, even though Date shouldn’t want anything to do with him, should have an omega who was honest and offered himself properly. Instead they were somewhere too open, not in his nest, not safe, not good enough. Date pulled his fingers out and it ached horribly.

Rather than confirming his thoughts and turning to leave, though, Date’s hands had come up to cradle his face. Ryuki was struggling to catch his breath, recognizing his own scent as the bitter, panicked one clogging his lungs. But Date was brushing fingers over his scent glands, hovering over him, and his frantic breathing slowed. 

The look in Date’s eyes stirred so much affection in his chest that self-doubt was stopped in its tracks. He had seen it before, when Date heard out his frustrations with work or found him on his own in Yoyagi Park. Here, he was just as vulnerable, just as certain that any comforting words were born from pity, but — but this was different. This had moved beyond what Ryuki could dismiss as lip service (figuratively, at least). In a state of such pure, instinctive, feeling, Date was with him, wanted the best for him, was trying to show him —

A few, last tears made it through as Ryuki’s breathing calmed. Date’s hands warmed and cooled him at the same time, giving a feeling of reassurance rather than temperature. And there was a soft, rumbling sound coming from… from his own chest? 

Date’s grin confirmed it as well as Ryuki’s own senses could. Unlike scenting, he did still purr on occasion, but by avoiding it in front of anyone else the instinct had moved further away. Sometimes, Tama told him, he purred in his sleep, but other than that it was rare. There was no room for shock now, instead he only tilted his head into Date’s touch and loosely hooked a leg behind Date’s knees.

“‘M not mad,” Date mumbled. “Just — could’ve been helping this whole time, could’ve taken care of you. You’re just too – too damn principled for your own good.” Satisfied with having scented him again, Date looked down between them and ran his hands over Ryuki’s chest, squeezed his waist, and set about unbuttoning his shirt. “Gonna make up for it. Gonna knot you so full, promise. You’re so good, omega, fucking perfect.”

Ryuki whimpered at the promise and dug his nails into the nape of Date’s neck to keep him there, to drag him down and kiss him, far too sloppy and open-mouthed. 

One of Date’s hands snaked down further. He easily kept their mouths connected while he reached, thanks to Ryuki’s position and shorter stature, and pushed two fingers back in. The over sensitivity had faded, only stinging for a second before heat washed over him again. 

Date tried to pull back from the kiss but Ryuki didn’t cooperate, locking his arms around his neck. Date didn’t make any complaint other than grunting at the extra weight as he tried to sit up and let Ryuki devour every bit of his mouth, barely giving him space to breathe. His neediness was more intense than before, more all consuming due to a combination of Date’s reassurances and the minutes ticking by. It wasn’t easy for Date to get a rhythm with his hand now that Ryuki was half sitting up, but that didn’t stop Ryuki. 

Hardly conscious of his movements, he shifted his hips experimentally at first, but with the encouraging way Date echoed his moans Ryuki was soon fucking himself on Date’s fingers in earnest. They were pressed so close now but not enough, still not enough. With his frantic movements, Date’s hand bumped between them to unintentionally press against his own cock. After the first brush, Date’s hips followed Ryuki’s to get any sort of friction. Ryuki hadn’t even noticed Date’s pants being thrown off and looking back later, couldn’t even be sure whether he or Date had made that move.

The heat of Date’s cock so near his entrance sent Ryuki spiraling towards orgasm faster than before. This was real – would be real, Date promised, Date was here, Date was so, so close to fucking him –

When Date pulled out his fingers to grind down directly, Ryuki’s vision went fuzzy and he cried out. That was enough for him to let go of the kiss (but not his hold on Date’s neck), gasping and shaking. It had been so sudden, every inch of him was wound tight and then cut completely slack again, though the pleasure lingered a bit longer this time. It wasn’t nearly as easy to replace relief with doubt when Date was letting him stay close and kept a hand at the small of Ryuki’s back while he came down.

Date ducked and hummed his satisfaction against skin before sitting back to regard Ryuki. His gaze was surprisingly soft, but something had shifted into his expression. He let his fingers dig into Ryuki’s thighs just a bit harder, fangs flashing when Ryuki whined at even a small touch. 

“Alpha,” Ryuki mumbled a few moments later, energy not fully returned but determination constant. “Need you, please.” 

After another moment under Date’s intense gaze, they moved in agreement, Ryuki scrambling to reassume his spot against the arm of the couch and Date climbing over him to eagerly kiss him again. His hesitation was gone as he slid between Ryuki’s legs. Ryuki couldn’t help arching his back at the position, showing off every vulnerable part of himself flushed with anticipation. Date let out a growl at the sight. As if Ryuki’s own need wasn’t enough of a motivation, Date’s restraint seemed to be breaking, his scent flaring up and intensifying into something confident, intentional, determined. He was going to do it, Date was really going to – Ryuki cried out, his train of thought replaced by the thrum of unmatched satisfaction as Date thrusted inside with no warning. With a couple brief moments of sinking in all the way, Ryuki was full.

He came again, somehow, and felt his calves twitching through it. His insides were desperate to keep Date here now, to get everything possible before letting him go, and clenched around Date’s cock even as he started to move. 

“Sh-shit, so tight,” Date’s hips stuttered on the first few thrusts. But then a fresh wave of slick urged him in further and eased each movement. By the time Ryuki had regained his breath and senses enough to feel it, Date was fucking into him freely, braced with one forearm on the back of the couch and the other hand grabbing one of Ryuki’s hips. 

Date seemed torn between holding him in place and pulling him down on his cock. As if Ryuki wasn’t writhing to meet each thrust and keeping his legs locked tight around Date’s back. Alphas may often have an advantage in physical size, but Ryuki was strong. He and Date had spent hours sparring, going toe to toe, proving that while Ryuki’s arms might always look like noodles, the strength in his thighs was no joke.

Date was considering trying to convince Ryuki to let him go just a little so he could actually get the leverage he needed, but an easier route presented itself. Ryuki whined and reached for Date’s face. When Date’s lips met his again, his small sounds evened out. The kiss was messy, unavoidably so when they were both still desperate to get deeper, but even the brief pressure of Date’s tongue and teeth were enough to relax his legs a bit.

No matter how much not heat-addled Ryuki wanted (and had spent years wanting) Date, the effort and promises of security were still needed during heat. And Date was doing so well to keep giving them to him, so well at everything, like always. Perfect, perfect alpha.

“More, p-please,” he groaned. It took effort to speak up and unhook his legs from where they wanted to anchor Date in place, but he was rewarded almost immediately. A low rumble and a marking bite to his chest showed Date’s satisfaction.

“So good, omega. Nice and tight, not gonna waste a fucking drop of my cum, are you?” When Ryuki gaped for a moment before starting to nod and babble promises, Date grinned. “Such a good boy.” Date pushed up onto his knees so that he could close both hands over Ryuki’s waist. He squeezed, moving them over his hips and stomach possessively as he spoke. 

“Should’ve known – hah – with fucking hips like these.” His words came with a few particularly harsh thrusts, pulling Ryuki to meet them and trying to reach as deep inside as possible. Ryuki’s moans were cut with gasps for breath. “God, always dying to grab ‘em like this, so hot. Just made for this, aren’t you?” 

“Y-yes!” Ryuki felt hot tears on his cheeks as his pride and eagerness to please Date were fed. Words were so hard until Date said them, until his alpha made everything obvious and easy and safe and good. “Made… made for you…”

Date’s grip and thrusts faltered for a second. “Holy shit,” he mumbled. Ryuki was too wrapped up in the feeling of being so perfectly filled to clock the momentary surprise and affection on Date’s face. He tilted his head up from the arm of the couch, finding his mouth dry. 

“Keep goi –” All the air was punched out of his lungs when Date started moving again. This time, his pace was much harder and more desperate. Every drag of Date’s cock against his walls sent electricity straight to Ryuki’s core and had him crying out. The sound of his voice wasn’t important in the slightest, wasn’t relevant except in its ability to urge Date on, but even through the haze Ryuki knew he was being loud.

What did matter was the sound of skin against skin, of Date panting above him, of his mixed groans and curses when Ryuki grabbed mindlessly at his chest. The best, of course, was when Date said his name like he needed Ryuki just as badly as he needed him.

Too far away, his omega chided, prompting Ryuki to whine and slide his hands up as far as they could go, just barely reaching Date’s shoulders. Too far to bite. 

Date was too lost in his own instincts to notice right away. Ryuki’s reaching hands were just evidence of one thing – he needed this, needed him, needed to be knotted and filled and his – and Date was more than happy to deliver. Saliva was pooling in his mouth at the thought. Even if he had the clearer head, even if he knew the things he shouldn’t do, Ryuki just couldn’t stop showing off his bare neck or twisting to try and get closer and show Date his bonding site.

He bent closer and a measure of tension left Ryuki’s body once he was able to lace his fingers together behind Date’s neck again. It was so comforting to touch everywhere and Ryuki wished that he could have more of Date’s skin against his, more of his scent, enough to block out everything else.

A wave of possessive pheromones washed over him as if on demand. Date’s thrusts were speeding up, keeping him from taking deep breaths, only able to pant and gasp and arch into the feeling of that cock he needed so badly pushing in so deep. Ryuki found the strength and roll his own hips to try and take even more but found that instead. 

Even hotter than the rest of him, the base of Date’s cock was swelling and pressed up against Ryuki’s hole. They both sucked in sharp breaths – it was like Date hadn’t realized that he was so close to knotting either, eyes as wide as Ryuki’s. Ryuki threw his head back again, keening and baring his neck and unable to find words to make Date please, please keep his promise. Date knew, though, letting out a growl and pushing his knot right to Ryuki’s entrance again once, twice, and –

Ryuki’s instincts were rebelling before his brain could feel Date’s absence, screaming for him to do something and hurry and keep him from leaving and oh, now it’s going to happen, alpha’s mad, didn’t do enough, wasn’t good, not good enough for Date’s pups, not good enough for –

“Shh, shh, don’t panic like that, omega.”

His body relaxed when Date’s voice came back. Still here. Not leaving, like he said, not going to leave. In those few seconds apart, Date had flipped him over and replaced his hands on Ryuki’s hips. With just enough strength to turn his head from where it rested on his folded arms, Ryuki caught Date’s gaze just as he lined himself back up with Ryuki’s leaking pussy.

“Just keep, keep being good for me and – fuck – take my knot, okay?”

Ryuki moaned as Date pressed back in. His insides tightened, throbbed, greedy and so fucking close to getting what they needed. Curling his fingers into the fabric he was leaning on, Ryuki weakly rocked back when Date started to move inside him again.

“Y-yes, please. Need you. Need it, please.” Date’s knot caught on his rim with each thrust. It wasn’t like Date was trying to tease him, Ryuki just needed to relax and accept it properly. Date bent over him to hug Ryuki to his chest and that was what he’d needed, that was the skin to skin touch he’d been craving. Date was everywhere and perfect and just for him and keeping him so, so safe. “Ah, – I’m –! Alpha, yes, yes, Date –!” 

He’s rapidly losing track of what specifically he wanted so badly, but he needs it, he’s sure, so he keeps babbling and whining and rocking with Date’s thrusts until finally – 

“T-there you go — fuck, fuck, that’s it.” Ryuki’s head fell to the fabric as he took Date’s knot in completely. Nothing in his field of view registered. Date ground forward, panting and working himself further in with shallow thrusts. He was so close to Ryuki’s deepest point, so close to coming and linking them together. Then the last of that ache in him would vanish and he’d be so full of Date that nothing could take it away. All of his senses were rushing toward that too, as even the cloth against Ryuki’s cheek was full of nothing but Date’s scent. 

“Ryuki, coming, going to make you so –” Date couldn’t finish his sentence before Ryuki came harder than he ever had before. The pleasure flaring through all of him was spasming and white-hot. Date growled and gave in to his throbbing cunt, coming with a cry that he muffled into Ryuki’s shoulder. 

The sting of teeth where he didn’t need them faded into the background because fuck Date’s knot was fully popped inside him, and Ryuki swore he could feel right where it met his womb, making sure none of Date’s cum leaked out. 

He didn’t hurt anymore. His skin had stopped crawling with need for the first time in what felt like years. He didn’t have the energy to be concerned with how he was drooling or contentedly staring into the unfocused distance. That is, until Date’s hands reminded him that the outside world existed again. He’d released his tight hold around Ryuki’s chest, one hand trailing to lay protectively over Ryuki’s stomach.

“‘S gonna take so well. Right here.”

Ryuki couldn’t manage anything other than a hum. He hoped Date was right, hoped they would stay connected even when Date’s knot went down, even when the heat in him faded. Date maneuvered them to slump slightly so they laid on their sides. Moving to cushion Ryuki’s head with his other arm, Date drew lazy patterns over his skin. They were both quiet and drifted in and out of light sleep for the better part of an hour. For Ryuki’s part, exhaustion was replacing every bit of neediness in his body and he was sure he’d succumb to the comfort of being held and fall deeply asleep shortly. He wiggled slightly in an effort to get even closer, pressing himself as flush back against Date as possible.

This jostled where they were connected, drawing a hiss of over stimulation from Date.

“Shit, ow.”

“‘m sorry,” Ryuki’s voice came out small and quiet. He hoped Date knew that he really was sorry, really wouldn’t ever hurt him on purpose. All that he managed, though, was, “Tired.”

Same, damn.” Ryuki snorted despite himself, fighting to keep his eyes open for only another few seconds before slipping into much-needed sleep.


Ryuki stirred when the warmth around him was tugged away. As he blinked awake and tried to take back control of his limbs, his brain was slow to recognize the dim lighting. A thin blanket replaced the item he’d been so dismayed to let go of – Date’s coat, tossed to the side – but blissfully held that same, comforting scent. Beyond the bed, he spotted a speaker system, a couch.

I’m at Mr. Date’s house… A hand sifted through his hair in confirmation. Ryuki instinctively turned his head into the touch before reality started to click together. Then that means – he brought me here, after we – 

The fact that Date was propped up behind him and out of view did nothing to calm the heat rising in Ryuki’s cheeks. How had that happened? How had he let it – how had he not noticed that – Ryuki squeezed his eyes shut to try and refocus, taking a deep breath.

“Mr. Date, I don’t – I didn’t –”

Date’s hand kept combing through his hair, his own breathing slow and deep. It calmed Ryuki’s heart rate, too.

“Later, later. We’ll both feel better talking when we’re not dead tired.” If later existed, that meant Date would be here, and didn’t… didn’t hate him. Ryuki repeated the thought himself, holding onto the unbelievably soft way Date had looked at him on the couch and the way his arms wrapped around him now. “Go back to sleep.”
