The two days between their conversation and Renji rolling out of bed as soon as the sun rises are uneventful enough, serving only to frustrate him and make the time feel as though it is passing painfully slower than usual. When he’d woken up the morning after, part of him wondered if it was part of an elaborate dream because there were more than enough fantasies and dreams that revolved around Byakuya confessing to him so Renji never has to do anything about the feelings that bubble up in his gut whenever he finds himself alone with Byakuya. At least when the rest of the pack is around, Renji can focus on them instead of his pack alpha. It takes self-control and discipline, but he can manage well enough.

When reality settles in and Renji realizes the conversation was serious and not a figment of his wishful imagination, he propels himself into action to make all of the preparations needed so he can vacate his position for a week to spend with Byakuya. The thought of sharing an intimate experience with  Byakuya — that Byakuya had come to him with the request instead of the other way around — leaves Renji floundering as he tries to figure out what he could have done to earn this. After all, Byakuya is one of the most sought-after omegas in the area and had given everyone the impression he would never go near another after Hisana’s death.

She had died before Renji joined the pack, though he heard enough to understand what happened. Byakuya closed himself off once Hisana died, deciding in his grief that no one would ever mean as much to him as his mate did. Renji understood that all too well, and respects Byakuya’s wish to remain alone no matter how much he wishes Byakuya would let him in and accept Renji’s desire to court him. But for now, this is more than enough.

His second night of sleep is tumultuous at best, but he sleeps enough that when morning begins to peak over the horizon, he leaps out of bed and prepares himself. Though Byakuya was insistent Renji should bring clothes with him, Renji only has a single change of them and is confident he won’t need much if any of them once he has Byakuya in bed properly. Byakuya might be stubborn but once the exhaustion sets in and he realizes just how much he wants Renji close to him just for the purposes of closeness and comfort, he won’t even remember that he thought Renji might need clothes in the first place.

The walk to Byakuya’s private quarters makes his skin crawl, his hands twitching as he forces himself to breathe slow and deep. Not a big deal, Renji, he tries to tell himself the closer he gets to Byakuya’s door, rubbing his hands on his pants, trying to ignore how sweaty his palms are. You’ve only been thinking about this very moment for years and all the ways you can screw this up and make him hate you forever. No pressure, right?

Before he can spiral into a self-deprecating well of negativity whose bottom is a black void, the scent of cherry blossoms reaches his nose. Byakuya’s natural scent, soft and sweet and subtly spring, almost like a soothing hand running down Renji’s spine and reminding him that Byakuya wants to see him and spend time with him, that Byakuya trusts him to do what Byakuya needs him to do which is far more credit than Renji deserves, considering. But he doubts there is anyone else in this world who would ever take care of Byakuya like he would.

It might be arrogant talking. Renji has known Byakuya significantly less time than most of the rest of the pack, having fought his way to Byakuya’s side specifically to get to know him better rather than to vie for the position of pack alpha. He thinks Byakuya might skin him alive if he ever finds out Renji intends on keeping the second spot all to himself, not intent on challenging Byakuya to a true fight when the position lets him keep anyone from ever reaching Byakuya. The last he can do is ensure Byakuya can live in relative peace and govern their pack without having to worry about outsiders or usurpers trying to take his position as alpha.

The stability had never been there in Renji’s old pack, and they suffered as a result under too many alphas who made too many rapid changes but were never strong enough to properly defend their position. More than once, Renji found himself desperate to prove he could do better, but no part of him wanted to clean up that mess. Byakuya took him in without a second thought when Renji appealed to him to join his pack, and Renji repaid him by climbing to the very top to make sure no one else ever had the chance.

He needs to stop being so sentimental. Sighing, he runs his hands through his bound hair, tightening the band holding his hair back out of his face before he raps his knuckles on the worn but glossy wood of Byakuya’s door. His ears pick up the sound of movement behind the door before soft footsteps approach and he takes a step back, not wanting to be inappropriately close— Does that even make sense? Can he be too close to Byakuya over something like this?

The door opens inward and Renji nearly swallows his tongue. In all of the time he’s known Byakuya, he’s never seen his alpha anything other than fully dressed. Now, Byakuya only wears a thin white robe made of what looks to be silk, the sash tied around his waist so loose the throat of the robe gapes open over his chest. The sight leaves Renji speechless, his eyes flickering over the flushed skin of Byakuya’s chest, the color high in his cheeks, the almost overpowering aroma of his scent this close. So he’d been right about his heat cycle coming on the same day each time. Renji is suitably impressed.

He can also tell Byakuya must have had a rough night from the dark circles under his eyes, the way he leans heavily on the doorway as if he has no energy. Just like Renji thought, Byakuya is already struggling to handle that strain. His body isn’t used to this any longer and was hardly prepared for the influx of hormones and the exhaustion of running through a process it hasn’t had the chance to become familiar with. It makes him want to carry Byakuya to bed, tuck him in and watch over him so he can sleep soundly and peacefully.

Calm the fuck down, he snaps at himself.

“Renji, you’re here.” Byakuya wavers on his feet and Renji’s entire body twitches with the urge to move forward and touches him, pulls him close and hold him. “I apologize for my appearance, but the evening was not a pleasant one and I didn’t have time to prepare myself. Come in.”

The words have Renji snorting as he steps into the room, waiting until Byakuya closes the door and locks it before stepping closer to him. “I told you that you were going to be tired.”

“I didn’t anticipate the strain to be quite so great. It’s been never-ending.” Byakuya presses his forehead against the door and Renji wonders if the cool wood is a respite from the heat.

He should ask but doesn’t, stepping into Byakuya’s personal space, arms moving to circle his waist and draw him back. As soon as he has enough space between Byakuya and the door he sweeps him up into his arms, the movements so quick and precise Byakuya barely has time to protest before Renji is holding him, carrying him across the expanse of the bedroom to his bed— Nest, as it were, a mound of carefully placed blankets and pillows.

Because Renji can never quite keep his thoughts to himself, he wondered what Byakuya’s nest might look like. Someone so minimalist might not even have one, and he’d toyed with the idea Byakuya might not even really know how to go about building one that would be comfortable for him, but his worries are laid to rest within moments. Though he has no doubts Byakuya keeps his bedding minimalist, the bed is an array of soft fabrics and pillows, space left in the middle large enough for two people. Renji’s throat closes at the sight. Byakuya thought about him.

“You smell good.” Byakuya noses at the side of his throat and Renji tilts his head, letting Byakuya nuzzle against his scent gland as much as he wants. “Or that’s the heat speaking.”

“Probably a little of both. I’ve known omegas who aren’t into sex who just keep alphas around to smell nice when they go into heat. It helps. Comforting, or something.” The same can be said for alphas in rut keeping omegas around to perfume their rooms for them, given that’s what Renji does. “If I’d known your heat started last night, I’d have come straight to you.”

Byakuya shakes his head. “You had no way of knowing. It was an eye-opening experience just the same. I don’t think I could have managed a week of this on my own.”

“Well, lucky that you don’t have to.” Renji moves carefully, dropping to a knee as he sets Byakuya down in the nest he’d prepared, marveling at the way Byakuya curls into the pillows, nuzzling into the one his head must have been resting on.

There is nothing sexual about the concept of nesting, the comfortable scents and warmth, the padding, the softness just making something small and familiar, a place where an omega can feel safe during their vulnerable moments. The satisfaction Renji gets from seeing Byakuya looking so comfortable and relaxed has nothing to do with desire and everything to do with the swell of emotion threatening to choke him, the fact that Byakuya has deserved this and is finally getting a chance to indulge himself just this once.

Renji’s hand moves before he can think about it, brushing long black hair off of Byakuya’s forehead. “You want some space, or you want me down there with you?”

“Come lie with me.” Byakuya looks up at him through long, dark lashes and Renji knows there is no earthly way Byakuya has any idea how attractive that looks. “Clothes… Take them off.”

His self-control cracks and Renji laughs, head tipping back even as his hands dart down to the bottom of his shirt, pulling it up and over his head. “I knew you’d come around to my way of seeing things. Are you going to keep your robe on or take it off?”

Byakuya seems to consider before sitting up slowly, deft fingers moving to the sash. “I suppose it would be more comfortable if I removed it. It’s done nothing but feel stifling.”

“Don’t keep anything on if it’s making you uncomfortable. Your comfort comes above everything else.” Renji’s hands stumble over the waistband of his sweatpants— it seemed stupid to wear proper clothes, given what he’s here for— when Byakuya unties the sash, shrugs his shoulders out of the sink, revealing more bare and flushed skin. “Taicho—”

Byakuya’s head whips toward him, stormcloud eyes pinning him in place. “Such formality in an intimate setting feels wrong. You may call me by name while you’re with me.”

“Oh.” Renji wets his lips, letting that revelation sink in. “All right. Byakuya, you’re gorgeous. ”

“Flattery will get you nowhere, Renji.” Byakuya shakes his head, as if the notion of being attractive is foolish to him, and works the robe the rest of the way off of his body.

Renji must have done something wonderful in another life, must have saved an entire planet or cured a deadly disease, to be gifted with the sight of a naked Kuchiki Byakuya in this life. The two of them have been as close as possible since Renji became his second— as close as they can be given the two of them are comrades and friends, maybe, but nothing more. They spend a significant amount of time together to sort through pack matters, and Byakuya has invited Renji to train alongside him more than once. Such behavior was abnormal in a pack alpha; most alphas kept far away from their pack beta, always aware that growing too close will leave their back wide open for the inevitable knife. No pack beta just settles for second, after all.

The difference is that Renji did, and he thinks Byakuya might have caught on to at least that much to trust him with this level of closeness. That aside, in all the time the two of them have spent together, in human skin and wolf skin, Renji has never seen Byakuya naked. Hell, he’s never seen him without a shirt on because Byakuya stays layered up even when his skin is soaked with sweat from a long training session. If there is a particular reason for this, Renji has no idea what it is. Maybe Byakuya just wants to keep other alphas away from him and refuses to so much as risk garnering their attention with exposed skin.

Which means Renji is likely the first person in years to see Byakuya exposed like this, and he gets to see all of him at once, thoroughly knocking the air out of his lungs.

Byakuya’s body is toned and muscular, broad shoulders and definition in his long and graceful limbs, the cord of muscle drawing Renji’s eyes down the length of his body. The stereotypes and societal pressures always concern themselves with soft omegas. Such an aesthetic is discouraged but it makes Renji’s mouth water, the physical evidence of just how hard Byakuya works to maintain this body. His torso tapers down into slender hips that give way to his thighs, thick with muscle, no doubt strong enough to keep Renji pinned in place no matter what position they end up in. His skin is as pale as white cherry blossoms though scars mark his skin, further evidence of just how hard Byakuya worked to attain his status as alpha.

It’s stupid to feel upset about those scars when Renji knows damn well Byakuya had won those fights, had to in order to be lying in front of him right now, but he can’t ignore the way his stomach gives a little lurch just the same.

Byakuya keeps his thighs pressed together, which Renji would have expected, so he lets his eyes trail back up instead, admiring how Byakuya’s skin is flushed with heat, the pink splotches uneven but daring Renji to touch. His hands twitch, wanting to map them out, the flush down his chest that nearly matches the pink of his nipples, the color dancing high under his throat. His hair is fanned out across the pillows but a few wisps here and there stick to his skin, a sharp contrast to how fair he is. Renji thinks he’s going to die.

“You’re staring at me.” Byakuya mutters, dark eyes narrowing. “Do you have something to say?”

This is the first time Byakuya has been with anyone since Hisana’s death, but Renji wonders distantly if there was anyone before her, someone who would have put that edge into Byakuya’s voice, that distrust in his eyes, or if he came by it through grief instead. “I’m going to be spending the next week getting intimately familiar with your body. Can’t I just look at you?”

The words seem to throw Byakuya off. He twists his head away, his cheeks burning hotter as he fixes his gaze on the wall. “I suppose.” He says, but he doesn’t sound happy about it.

“Okay, okay, I’ll stop.” Renji grins when Byakuya scowls up at him and then kneels on the edge of the futon, on the very edge of Byakuya’s nest. “Am I allowed to come in?”

“Yes.” Byakuya places a hand in the empty space beside him, the one he’d built into this knowing Renji would be here to take that spot. “I invited you here for that express purpose.”

Renji leans over, then leans back. “Did you eat before I showed up?”

“Yes. I’ve been awake since five. I couldn’t sleep any longer.” Byakuya catches his lower lip between his teeth and bites down, and Renji accepts this, pulling himself into the nest.

Most omegas have floral or otherwise sweet scents, and Byakuya is no different. His scent wafts up to Renji’s nose as he settles in the space Byakuya made for him, not trying to avoid touching him, letting their bodies brush as he settles down. “You smell like cherry blossoms, y’know.”

“I’m well aware.” Byakuya looks at him carefully for a moment, then rolls over, tucking his arm under his head. “What did you have in mind once we reached this point?”

“You’re so awkward about all of this. It’s kinda cute. If I didn’t know better, I’d think you were a virgin.” Renji laughs when Byakuya growls at him, a low rumbling noise in the back of his throat that makes the hairs on the back of Renji’s neck stand up.

When Byakuya speaks, his voice is low and dangerous. “Choose your words carefully.”

“I’m not saying it’s a bad thing. Just keeps putting things in perspective, that you haven’t done this in a while and all.” Renji stretches out a hand to touch Byakuya’s face, feeling the warmth under his hand, fingers slipping up into the fine black hair at his temple. The touch softens Byakuya immediately, his eyes falling shut as he presses his cheek into Renji’s palm automatically, his mouth opening around a soft gasp. “You’re pretty far gone already, huh? You really should have just come and got me.”

“Do we have to keep discussing how I spent the evening instead of you doing anything to make this easier on me?” Byakuya demands, though his eyes don’t open.

Renji leans in to kiss him because he can, because Byakuya asked him to come here so he could take care of him. Byakuya makes a small desperate noise against his lips and Renji’s blood burns, his hand careful on Byakuya’s skin, sliding around to the back of his neck to coax him closer. Their mouths fit carefully together, Byakuya’s uncertainty making this all the more exciting for Renji. He’s the one who gets to unravel Byakuya like this, who gets to kiss him and touch him and bring him to orgasm over and over until he can’t move anymore.

He nips at Byakuya’s lower lip and then sucks on it, his gut hot when Byakuya moans, a barely-there breathy sound. Renji rewards him for it, slipping his other arm around Byakuya’s body to pull him in close, pressing himself into Byakuya’s flushed skin as he licks into his mouth. Byakuya’s tongue is slow and clumsy but Renji works with it until Byakuya’s fingers dig into his shoulders hard enough to leave bruises. At least, he hopes they do.

“D-don’t tease me.” Byakuya whispers against his mouth, his voice low and husky.

“I don’t plan on that. Open your legs.” Renji hooks a hand in the back of Byakuya’s knee, pressing against the joint there until it bends for him so he can slip his own thigh between. Something easy to start, something anyone can do. Something to warm Byakuya up for him without overwhelming him. “Trust me to know how to make you feel good.”

He presses his thigh high until he can feel Byakuya hot and wet against his skin, the evidence of his heat-induced arousal clear. Byakuya’s voice hitches and it’s adorable, and if Renji ever says that out loud Byakuya might claw his throat out on the spot. So he kisses him again instead, open-mouthed kisses that are hot and wet as he rocks his thigh up against Byakuya’s folds, hand settling on his hip, coaxing him to move, too. Byakuya is slow and uncertain and then he makes a little noise against Renji’s lips, gripping his shoulders tight again.

“That’s right. You’re doing good.” Renji noses the line of his cheekbone, Byakuya’s scent overwhelming this close. He’s meant to smell good, to overwhelm Renji’s senses, to make Renji want to pin him down and fuck him until their bodies are wedded together. “I don’t care if it’s the middle of the night next time. Knock down my damn door if you really have to.”

Byakuya moans when Renji laps over his scent gland, the nerves there sensitive, and Byakuya’s scent punches him in the face. He presses his thigh harder against Byakuya in response, enjoying the way Byakuya’s body shudders and jerks against his own, desperate for friction even as he slicks Renji’s skin. Renji can only imagine how tight he is, how good it’s going to feel to work his fingers inside, listen to Byakuya’s high keen of pleasure every time he comes around Renji’s fingers, around his cock.

Renji isn’t going to survive this, but that’s fine.

“Renji.” Byakuya whines, and Renji’s cock jumps at the sound, his entire body jolting in response to Byakuya’s sweet desperation. “I— I need—”

In answer, Renji nips at his throat, gripping Byakuya’s hip tighter, moving Byakuya’s body faster against his own. “You’re almost there, baby, c’mon. Come for me, you can do it.”

When Byakuya comes, it’s with a strained little sound, his eyes squeezing shut while his body quakes against Renji’s own. His body trembles and jerks with the small after-quakes rocking his body before he presses himself down into the sheets, panting softly, eyes opening slowly behind the feather of his dark lashes. Renji rewards him with a kiss, running his hand through Byakuya’s hair, petting him in an attempt to calm him down.

“Very good.” he murmurs against Byakuya’s lips, laughing when Byakuya only growls at him in response. “I just needed to wind you down a little. All that talk about how just jumping right in is better is shit. You were too tense for anything I want to do with you.”

Byakuya blinks lazily at him, shifting his thighs apart so Renji can ease his out. His skin is wet and slick, shiny under the morning light from Byakuya’s orgasm. “Is that so?”

Renji hums and nods, and he can’t really resist the urge to run his fingers through the slickness on his thigh, lapping it up. He moans, because it’s good and to see Byakuya’s eyes widen, the outrage dancing in his vision prompting a little laugh out of Renji that he loses track of in seconds when Byakuya punches him in the shoulder. It doesn’t hurt but it startles him enough and Byakuya scoffs at him, nuzzling down into his pillows once more, obviously satisfied.

“I can’t believe you brought me here just to beat me up.” Renji jokes, stroking a hand down Byakuya’s bare side, feeling the muscles there still fluttering, Byakuya’s side rising and falling slowly in time with his breathing. “What do you want me to do with you in particular?”

Byakuya shrugs, not opening his eyes. “I don’t have anything in mind. Just do what you want.”

“Your wish is my command, omega.” Renji leans in for another kiss, then presses a hand to Byakuya’s shoulder. “Lay back for me. Relax. And if you have the urge to squeeze my head between your legs, feel free. I’m not going to lie and say I’m not into it.”

“What?” Byakuya tries to sit up instead and Renji hooks an arm around his shoulders, pulling him back down. “What are you talking about?”

Renji scoffs and noses his cheek. “I’m going to eat you out until I can’t feel my tongue anymore, so my head’s gonna be between your legs. If you wanna squeeze, go ahead. I’m into that.”

“Of course you are.” Byakuya shakes his head but stretches out on his back and Renji takes a moment just to admire him before he slides down to the foot of the futon, nudging Byakuya’s thighs apart. “Do I need to specify you’re allowed to do more than just—”

“Nah. I know I’m allowed to mount you. There’s no fun in just jumping right in, though.” Renji could go through the spiel about how orgasms will take the edge off just as well as sex will, that Byakuya’s more likely to enjoy everything if he’s relaxed instead of trying to get Renji inside of him, but it’s better to show him. He can’t argue with facts.

Byakuya sighs and lets Renji settle between his thighs, looking down at him, and the slight pink that burns in his cheeks isn’t just from heat. “Are you comfortable down there?”

“Oh yeah. The view’s great.” Renji smirks and Byakuya thumps his head back into the pillows in response, and it takes everything in Renji not to laugh. “Just relax and let me take care of you, Taicho. I told you before I know what I’m—”

“Don’t call me that.” Byakuya reminds him.

Shit. Right. “Relax and let me take care of you, Byakuya. I know what I’m doing, and believe it or not, I know what you need. You’re not gonna walk away from this unsatisfied.”

“If you say so.” Byakuya murmurs, like he doesn’t quite believe it.

Renji has ways of showing him just how serious he actually is.

He needs to stop staring so much, and he knows that, but being up close with Byakuya like this is a little bit different and a little bit harder, all things considered. His folds are wet and swollen and slick with need and Renji can hardly ignore the scent of him this close, the way it smacks him in the face and draws him in at the same time. The dark curls around Byakuya’s folds are wet and matted to his skin and Renji brushes them back carefully, listening to the way Byakuya’s breath hitches at just this small touch before he leans in and kisses him.

It’s not the immediate gratification Byakuya expects, surely, but Renji takes his time, placing open-mouthed kisses on Byakuya’s folds before sucking the moisture off of them. Byakuya whines softly above him and Renji’s back breaks out in goosebumps at the sound. It’s good he feels good because of me I’m the one doing it loops through his head and he tries to ignore how hard his cock is, how much it aches and throbs, and refuses to touch it.

The tip of his tongue traces the part in Byakuya’s folds, easing them apart, the silky wetness on his tongue threatening to undo him. Not that he was ever done to begin with. His eyes fall shut so he can focus on just this, the taste of Byakuya on his tongue, lapping over every sensitive part of him. He traces careful circles over the hood of Byakuya’s clitoris before easing it back with his thumb, licking over his clit directly, the contact wringing a little cry from above him.

“Renji, you—” Byakuya breaks off and his hands are in Renji’s hair, gripping him by the ponytail, holding his head in place. “Don’t stop don’t stop don’t stop —”

As if Renji could stop now.

He runs the flat of his tongue over Byakuya’s clit until Byakuya’s thighs do as he knew they would, clamping shut around his head, fingers in his hair twisting until his scalp prickle at the sensation. There’s something about Byakuya manhandling him like this that turns him on even more and he rewards him for taking like this, sucking on his clit, humming with his lips fastened on those delicate nerves until Byakuya writhes beneath him, against his mouth.

It’s hard to think about coming up for air when Byakuya whines and whimpers and mewls for him, the litany of sounds surprising because Renji was sure Byakuya would make him work for every little noise. But he’s not the one who’s gone years without this, years without maybe sex of any kind, so Renji does his best, breathing through his nose as he licks over and around Byakuya’s entrance. Wetness smears across his chin, slicks his lips as he thrusts his tongue inside and groans, soft and low, at how the muscle flutters and clenches around him.

He wants to use his fingers but not yet, fucking Byakuya with his tongue, his nose nudging up against his clit every time he moves his face in a little closer. His head almost hurts from the pressure, Byakuya’s thighs keeping him pinned in place, hands holding his head right where Byakuya wants it. All Renji can do is open his eyes for a moment to look up at Byakuya, shocked to find those dark eyes fixed on his own, Byakuya’s lips bitten red and swollen.

He’d been trying to be quiet and Renji had broken him of it. The thought makes him throb.

Renji tears his mouth away even though his every instinct is telling him don’t do that and smirks up at Byakuya. “How are you doing up there?”

“F-fine.” Byakuya says, but his voice quavers and the hands in Renji’s hair shake. He can see the muscles in Byakuya’s thighs jumping, can almost hear the riotous pounding of his heart against his ribcage. “Renji, can you just—”

“Make me.” Renji licks the moisture off of his lips, watches Byakuya’s eyes spark gold for just a moment. And then Byakuya makes him, just like Renji told him to.

His hands jerk, the elastic in Renji’s hair snapping from the pressure as he’s shoved back between Byakuya’s thighs, his mouth sliding against his folds until he does as he’s obviously being told. His tongue snakes back inside of Byakuya, fucking him slowly and leisurely, his hand slipping over Byakuya’s mound so he can rub circles into his clit. It’s enough to have Byakuya shaking against him once more, the dual stimulation obviously pushing him close to his limit, but he doesn’t tell Renji to stop, pressing himself wet and messy against Renji’s mouth.

If it was anyone else, Renji might be a little mean, might snark and tease and edge close to orgasm without ever getting there. But it’s Byakuya, who struggled so much just asking for this, who suffered all night long rather than just ask Renji to come to him early, who grew defensive at something as simple as staring, as teasing. So Renji’s tongue moves faster, more earnestly, and his fingers slide over Byakuya’s clit until Byakuya’s entire body jolts and he cries out, loud and sweet. His thighs clamp down so hard it hurts but Renji only groans, licks him harder.

When Byakuya finally goes limp beneath him, legs falling open, Renji leans back to look at him. He’s flushed red between his thighs now, the result of Renji’s mouth and fingers, his entire body shuddering lightly as he comes down from the orgasm. Carefully, Renji leans over him, places his hands in the pillows beside Byakuya’s throat so he can kiss him. He’s so tired he just lies there, lips moving slowly and lazily against Renji’s own, whimpering against his earnest kisses.

“You’re an asshole.” Byakuya tells him, his voice soft and lacking any real edge, any venom.

Renji grins and nips at his jaw. “Yeah.” He says, “But I think you kinda like that about me.”

“Awful. Who could ever?” Byakuya puts a hand on his shoulder, just sets it there, his fingers pressed lightly into the cords of Renji’s muscles. “I’ve not done anything for you yet.”

The words have Renji snorting. “That’s not that point of me coming and spending the week with you, y’know. I came here to take care of you, not the other way around.”

Byakuya scowls up at him and then shifts, and Renji tries very hard not to make a sound when Byakuya’s stomach presses up against his cock. He’s hard and hot and he wants to touch himself just to take the edge off, but he doesn’t at the same time. “Is that so?”

“Who knew you had it in you to tease? I’m impressed.” Renji kisses the tip of Byakuya’s nose, laughs when Byakuya scrunches his face up. “You need a break. I know you’re tired now.”

“You flatter yourself. I’m fine.” Byakuya is quiet, his expression thoughtful, and then he squeezes Renji’s shoulder. “Switch places with me. Lie down, I mean.”

Renji debates about that for a moment. “Why? Didn’t I just say you don’t have to—”

“Stop arguing with me.” Byakuya slaps his shoulder, the sound echoing in the room. “Just do it.”

The last person Byakuya had been with is Hisana, so Renji wonders even as he lets Byakuya half-wrestle him down into the nest, never one to do anything without a fight. He’s surprised Byakuya can still move at all, though he can see the trembling in his limbs and knows he’s fighting his own exhaustion to do this. It makes him shut up and let Byakuya do as he wants for a moment, a surprised noise leaving his mouth when Byakuya mirrors his position from a moment ago, fingers pushing his own hair back out of his face.

“No.” Renji tells him, and Byakuya frowns up at him, obviously displeased. “I mean, no, you can suck me off if you really want to, just not in that position. Lay on your side like an L for me.”

Byakuya narrows his eyes up at him and Renji wants to scream. “Why?”

“Because I can touch you like that.” He says plainly, and Byakuya blinks a few times up at him before shifting, tossing his legs out to the side like Renji asked him to. “Have you ever done this before? Blown a guy? Cause if not, I can tell you how to actually do it.”

“It can’t be that difficult.” Byakuya mutters, wrapping a hand around Renji’s cock.

The touch of his hand alone is enough to fuck up Renji’s train of thought for a moment. He almost chokes when Byakuya strokes him, fingers gliding over him in such a way that Renji thinks knotting toys and then stops thinking at all. It’s not exactly going to get him anywhere to think about Byakuya having sex with anyone else anyway. He should be focusing on the omega in front of him instead of letting himself wander down some fantasy that isn’t as good as this.

“Go slow.” Renji warns him, ignoring the way Byakuya frowns at him. “If it feels like you’re going to choke, then stop. I’m not one of those freaks who tries to choke their omega on their cock.”

“A real gentleman.” Byakuya says, his voice light enough that Renji knows he’s teasing, and he’s marginally surprised Byakuya can. Maybe it’s the orgasms talking, actually.

He runs his fingers through Byakuya’s hair, gathering it up in one hand before draping it over his thigh, keeping it tucked out of the way. Having long hair lets him know just how much it can get in the way and how. “Use your tongue, too. It’s not all just about the actual sucking.”

“I’m not a virgin, you know.” Byakuya licks his lips and Renji’s brain short circuits for a moment, not recovering fast enough before Byakuya leans in and licks the head of his cock.

Renji has had his fair share of fantasies about Byakuya, more than a few of them lewd and sexual, but there’s something about the idea of Byakuya’s mouth on his cock that never failed to get him going faster than anything else. Hell, he’d never thought he’d get to kiss Byakuya, never mind having Byakuya’s tongue curling around the head of his cock, lapping up the pre-come smeared across the head before he folds his lips around him. He doesn’t miss the way Byakuya’s lashes flutter and he wonders, distantly, if this is good for Byakuya too.

He needs to stop thinking about that immediately before he comes right now and here.

Byakuya might not have done this with someone’s actual dick before but he’s done something like it based on the way he sucks Renji’s cock, tongue curling around him as he goes down, his eyes finally falling shut. His cheeks are just barely pink now, his cheeks hollowing carefully as he takes Renji further in, and Renji’s breath hitches at the sight. He’s not going to survive today at this rate, how the hell is he supposed to survive a week of this?

Renji lets him work up to slowly bobbing his head before he stretches a hand down, fingers slipping between Byakuya’s thighs where he’s still wet. He’s not dripping quite as badly now which means his body is slowly winding down, a blessing, but Renji still slips a finger inside of him without any resistance. Byakuya moans softly around his cock but doesn’t stop, a blessing, a fucking gift from the gods to be sure, and Renji angles his hand so he can brush his thumb over Byakuya’s clit even as he works his finger deeper.

“You’re actually good at this,” Renji says, hissing softly when Byakuya licks up the underside of his shaft over the vein there, swallowing around him until Renji groans. “Fuck, Byakuya…”

When Byakuya pulls off to take a breath, his eyes opening slowly, Renji takes advantage and presses a second finger inside of him, hooking them up against where he knows that spot is supposed to be, pleased when Byakuya moans.

“You won’t let me do anything for you, will you?” he asks even as he shifts his thighs wider apart, giving Renji more access. “Even when I want to.”

Renji grins at him, fucking Byakuya with his fingers, unable to not hear the slick wet sucking sounds every time his hand so much as twitches. “Maybe after I’ve got you knotted and I know you’re not going to be as bad off as you were when I walked in.”

“You’re so concerned— Stop that.” Byakuya’s breath hitches when Renji presses the pads of his fingers into that spot, massaging it in slow circular movements that make Byakuya’s entire body shake. “I’m not going to be able to focus like that.”

“Who said I wanted you to be able to?” Renji smoothes his free hand down Byakuya’s face. “Feel free to go back to it if you’re so determined, though.”

Byakuya takes Renji back in his mouth and Renji eases a third finger inside of him, listening to the little noises Byakuya makes around him as he does. His moans vibrate along the length of Renji’s shaft, threatening to tip him over the edge he clings to because he is not going to come in Byakuya’s mouth. He wants to come with Byakuya beneath him, sunk so deep in his body it feels like they’ll be that way forever.

Renji’s determination matches Byakuya’s well. He holds out to the best of his ability even as he fucks Byakuya open with his fingers and eventually Byakuya pulls off of him for real, panting softly, lips swollen and wet. Renji pulls his fingers free so he can pull Byakuya into his lap, sitting up so he can kiss him, the taste of his own pre-come on Byakuya’s tongue and lips. The position is a mistake, Byakuya grinding down against him, teeth tugging at his lip a little harder than he expects. Byakuya is frustrated, and Renji can hardly blame him.

“How do you want it?” he asks, hands smoothes up and down Byakuya’s back, his own hips bucking up against Byakuya when his pack alpha rolls his hips down again. His cock brushes against Byakuya’s slick folds and his head spins.

“This is fine.” Byakuya reaches between them, grasps Renji’s cock in hand and presses the head against his heat, head falling back as his entire body shudders. “Renji, help me. ”

It’s not how Renji thought the first time would go but he does as asked, shifting Byakuya forward and thrusting up into him, face buried against his throat when Byakuya whines at the initial stretch. Renji’s an alpha and it shows, his cock long and wide and he’s worried that it hurts but then Byakuya rolls his hips down hard and Renji chokes, his hands gripping Byakuya’s hips to keep him from going too fast, too hard. The last thing he needs is Byakuya hurting himself on day one and he doesn’t think he’d ever live it down if he knew it was his fault.

“You feel so good.” he rasps against Byakuya’s throat, his own body shaking from the tightness, the wet slick slide of his cock as Byakuya takes him deeper, the way Byakuya’s body feels in his arms. It’s perfect and better than all of his fantasies combined. “Fuck, Byakuya, I can’t—”

His hips stutter and he groans, mouth open against Byakuya’s skin, tongue sliding over his scent gland as he pulls Byakuya’s hips down until they rest flush against his own. It’s hard to process anything but Byakuya, his hair sticking to Renji’s skin, his arms around Renji’s shoulders, the cherry blossom perfume of his scent clouding the air. Every inhale is just his scent, coating Renji’s throat and the inside of his nose until he feels consumed and surrounded, and it’s exactly what he’s always wanted and so much more.

Byakuya doesn’t give him time to really process this though, impatient and needy and being full doesn’t scratch the itch just yet. His hands scramble beneath Byakuya’s thighs, helping him ride Renji the way he wants to, gravity bringing their bodies together every time he comes back down. He’s slick and hot and he grips Renji so tight that Renji thinks he’s going to die from it, the pressure and friction just right for what he wants. He’s worried it might be too much for Byakuya but Byakuya only whines and tries to ride him harder and faster.

“Easy.” Renji warns him but Byakuya kisses him hard, their teeth knocking together for just a moment before Byakuya calms down enough to kiss him properly.

But it’s not the best position so Renji rolls them over and pulls out, ignoring Byakuya’s frustrated growl. He moves faster than he has all morning, getting Byakuya onto his knees so he can take him from behind, hand braced beside his on the futon. It’s better for knotting and Renji likes being able to blanket Byakuya’s back with his chest, face pressed into his long black hair, knees keeping Byakuya’s thighs spread wide while he fucks him at his own pace. Byakuya lets him, braced on his forearms, face hidden behind his hair.

Renji noses Byakuya’s neck, slides his hand over until Byakuya takes the hint and links their fingers together, tilting his head back until it rests against Renji’s shoulder. He’s panting harshly around his moans, his hips finally moving back against Renji’s, taking him as deep as he can. It doesn’t take much more for Byakuya to come like this, whining softly, trembling in the cage of Renji’s arms, against his chest. Renji stops moving, lets him breathe through it.

“Knot me.” Byakuya growls at him, squeezing his hand so tight it hurts.

“Thought you’d never ask.” Renji wraps an arm around Byakuya’s hips to hold him in place, presses his cock as deep as it’ll go and lets it swell until Byakuya’s breath hitches.

It’s always a tight fit but Byakuya takes it well and once he’s secured inside, Renji rolls them both over onto their sides as carefully as possible, hugging his body against Byakuya’s as tight as he can before he drags a blanket up over them. Byakuya makes a content sound and settles down in his arms, his cheek resting against Renji’s bicep.

“Tired.” he murmurs, scrubbing his cheek against Renji’s skin a little.

“I know, baby.” Renji presses his cheek against Byakuya’s hair, arms wrapped around his waist. “Go ahead and sleep. I’ll be right here when you wake up.”

He waits until his knot goes down to slip out but by then, Byakuya is already fast asleep. Renji settles in behind him, content to lie here and wait for him to wake once more.
