mine to ruin, mine to wreck

Summary:

“Seishiro,” he drawls, voice husky with laughter. “Ah— be gentle— god, you really don’t have an off switch, do you?”

Nagi’s lips drag over the column of his throat, wet and hot, nipping and sucking and mouthing at every patch of skin he can reach. “Don’t need one. Not with Reo.” His breath shudders, his voice dropping to something rougher. “Well, Reo made me this way. Reo’s gotta take responsibility.”

Reo laughs, but it breaks into a gasp when Nagi nips at the hollow of his collarbone. “Irresponsible little mutt,” he chides, but his fingers curl in Nagi’s hair, pulling him closer instead of pushing away. “So desperate you’d take me on the kitchen counter?”

(or: reo has a moment where he's worried nagi might disappear. nagi can't have that happening, not when he's content to live in reo's arms forever and ever after. well, if reo won't listen to words, nagi will have to prove it with his body.)

Work Text:

Nagi can hear Reo's shriek from across the house. "Nagi— Nagi, where did you go?"

 

He winces. Reo's loud. It's barely morning, and Reo was the one that'd gotten up first, anyways. He's got a whole morning routine, and apparently Nagi has timed his wake-up wrong. By Reo's rules, it ideally should've been after Reo got back, but Nagi is pretty shit at following the rules. Besides, Reo will forgive him anyways.

 

As if summoned by thought alone, Reo rushes into the room. He's not dishevelled, per se, but he is artfully stressed—eyes wide and limbs shaky, mouth twisted into some horrified expression, brows furrowed to the high heavens. He heaves—once, then twice, then thrice, to steady himself—and there's a fine sheen of nervous sweat along the planes of his chest, tastefully exposed by his silken post-workout robe. Yeah, Reo's hot when he's stressed. Well, Reo's always hot, but the point still stands.

 

"Nagi," Reo says. His voice is strained. "I told you not to leave the room."

 

Nagi takes a sip from his mug. The honey-lemon tea burns his tongue, so he holds his lips shut and pointedly stares at Reo. There's something even the super-elite is capable of forgetting, after all. Or maybe he does it on purpose. Reo's a lot of things, and spiteful is definitely one of them. Honestly, Nagi's not sure how he ended up with a sadist for a little boss, but, well, that side of him is beautiful too.

 

"Okay, fine," Reo seethes, crossing his arms over his chest. "If you want to do this the hard way, we can do this the hard way. Seishiro, pay attention to me."

 

"I'm always paying attention to Reo," Nagi says, conceding and dropping his minute vow of silence. A machine behind him beeps, and Nagi's ears perk up. "Oh, yay. Reo's coffee is done."

 

At that, Reo's whole demeanour softens. Nagi doesn't get why it's so surprising to Reo that Nagi's made coffee for him. Nagi's done far more before—and yet, every tiny thing seems to shake Reo to his very core. He eases out of his anxious state, jitters and stiffness ebbing till Nagi's beautiful wife steps out of his shell. No longer mad—or no longer able to hide behind the fact that he was mad—Reo rushes forward to press a kiss to Nagi's cheek. Nagi hums, preening under the gentle affection, leaning against Reo until he shuffles backwards, unprepared to handle his weight, and ends up pressed up against their kitchen island.

 

"Mornin', Reo," Nagi says, pressing a kiss to Reo's flushed-pink forehead, his hands drifting up under Reo's robe to paw at his sides. "Is this still doing things the hard way?"

 

"Mmmgh," Reo grumbles petulantly, burying his face in Nagi's chest, arms winding around his waist and squeezing tight. "You scared me…"

 

"Mm, well, Reo's always anxious," Nagi says. "That hasn't changed in all these years, hm. Still, it's not like I've ever tried to leave before, so I don't get why Reo's so worried. We made a promise, right?"

 

"But, Nagi—"

 

"Your coffee will get cold, Reo. My tea, also. Ne, Reo— if iced lemon tea is good and hot lemon tea is good, why does lukewarm lemon tea taste bleh?"

 

Reo huffs a half-laugh and squeezes Nagi harder, his nails digging into Nagi's back. The pads of his fingers drag over the still-raw red lines from last night, and Nagi shivers. It's probably intentional; he can feel Reo smile against his chest. Well, it's not like he minds—if that's what the boss wants, who is he to disagree?

 

When Reo is sufficiently mollified enough and pulls back to grab his mug, he keeps as much of his body pressed up against Nagi as he can. Nagi's hand comes to rest at Reo's waist, it's natural resting position.

 

Reo takes a sip of the coffee and smiles. "Hey, it's drinkable this time," he says, humming to himself. "You've gotten better at this, Seishiro~"

 

"Mm, yeah," Nagi says, though all he's really done is press a button and wait. "I'm a genius, and all that. Yay."

 

Reo grins, bright and beautiful, and Nagi feels his heart flutter in his chest. Even after all these years, Nagi hasn't managed to build up any sort of resistance to that one-billion-watt superpowered smile; it's not like he wants to be immune to it, but it would be nicer if Reo's phone didn't beep loudly every time, alerting them both to Nagi's elevated heart rate. It made him look kinda lame.

 

"Oh?" Reo lilts, wiggling his eyebrows at Nagi as he takes a slow sip of his coffee. "Are you feeling a little flustered, Seishiro?"

 

In his defense, if Nagi knew his vitals were being streamed to Reo's phone in live time, around the clock, he probably would've put up a little more of a fight. Don't get him wrong, he loves the arrangement they have now. It's nice, being together forever. But the microchipping can get a little embarrassing. The tracking was one thing—Nagi had Reo's location at all times too, after all—and, really, the shock mechanism didn't bother Nagi because he was a perfectly good boy where Reo was concerned, but the vitals kept giving him away. It was kinda cringey to broadcast the fact that he couldn't handle his own reactions to Reo, and sure, while Reo had said I'd never find my beloved Seishiro uncool, because my treasure is the number one most interesting thing in the whole universe, Nagi still felt a little pathetic about the whole thing. Then again, Reo seemed endlessly entertained by it all, so maybe it was worth it.

 

"It's Reo's fault," Nagi says petulantly.

 

Reo laughs. "I'd sure hope so. There better not be anyone else getting you all hot and bothered aside from your dear wife. That's why I have to keep an eye on you."

 

Nagi sighs, heavy and deliberate, setting his mug down with a clink. “Reo already knows he's the only one that can have me flustered,” he mutters, voice flat but soft. “Reo doesn’t need a whole machine telling him.”

 

Reo gasps theatrically, clutching at his chest like he’s been mortally wounded. “But it’s cute! What if I miss something? What if your heart flutters and I don’t notice? What if—” as if catching on something, his mock drama bleeds into a real coldness. “—what if you get stuck and almost die, and I miss it because I don't know?”

 

Nagi tilts his head, blank and unimpressed. “If I die, I’ll tell you. Besides, Reo's the only one who can kill me.”

 

That earns him a laugh, warm and loud, spilling out of Reo like sunlight breaking through storm clouds. He leans forward, pressing another kiss to Nagi’s jaw, careless of the faint tea-sweet stickiness there. Reos moods have never stopped being as shifting as the tides, Nagi thinks, but he's at least grateful for the way it means he brightens up just as quick. 

 

“You’re so ridiculous, Seishiro,” Reo murmurs against his skin.

 

“Mm. Takes one to know one,” Nagi says, arms tightening around Reo’s middle. He doesn’t plan on letting go anytime soon, or ever, really. The steady thrum of Reo’s heartbeat against his chest is more important than tea, or coffee, or rules about not leaving the house (or bedroom, now, apparently) when Reo can't see him.

 

Reo wiggles in protest, though he’s still smiling. “You’re crushing me.”

 

“Then don’t be crushable,” Nagi replies, shifting his weight just enough to cage Reo against the counter without actually squishing him. “Besides, Reo likes it when I hold him.”

 

Reo bites his lip, trying to look stern but ending up more along the lines of sexy, but his eyes soften the way they always do when they look at Nagi. The fake-fight drains out of him, replaced by that too-bright fondness that never fails to hit Nagi square in the ribs. “Yeah,” Reo admits quietly. “I like it too much.”

 

Nagi hums, satisfied. “Yay. Don't run off, then. Stay here. Drink your coffee. Reo gets a headache if he misses it, right?”

 

For once, Reo obeys without argument. He presses a delicate kiss to Nagi's collarbone, pleased, and Nagi shivers under the attention. Even this reaction, too, is Reo's. Reo leans back against the counter, sipping from his mug, scrolling through the news on his phone. Their breaths are in sync in the quiet kitchen, and Nagi wondders if he holds his breath in time with Reo, if they could sync up and become one person.

 

Aside from the quiet noise of them existing, the faint hum of the house is the only other thing the spaces where words might go. They've never really needed words, anyways. Nagi doesn't like talking much, but Reo always knows what he wants. The things Nagi wants are simple, maybe. Easy. Really, Nagi thinks this is the best kind of morning, Reo warm in his arms, safe and bright, fussing over him one second and melting against him the next. If all he has to do is put up with a few beeps and a Reo-branded phone app that sells him out, maybe it’s worth it.

 

Reo's phone pings again and his mouth twists suddenly, as if surpressing a laugh. He stands tall, pressing his mouth just shy of Nagi’s earlobe, mouth warm against his cheek. “Seishiro,” Reos voice dips low, tone mischievous. “Your heart rate just spiked again.”

 

Nagi groans, burying his face in the warm crook of Reo’s neck. “…Reo’s annoying.”

 

“And you love me,” Reo says, teasingly triumphant. He never says those words like he truly believes them, even now. Nagi doesn't get it. Why would he be here, if not for the singular fact that he loves Reo? from his birth, to his life, to his death, Reo is everything, isn't he?

 

Nagi doesn’t argue. He just holds tighter. It's true, after all, to him, loving Reo is probably even easier than breathing. "Yeah," he says against Reo's skin. "I do."

 

Reo’s coffee mug clinks faintly as he reaches back and sets it down on the counter, but he doesn’t move away. He just stands there, all flushed skin and lazily-hanging robe and kiss marks half-hidden beneath its silk, like he knows exactly what kind of fire he’s stoking in Nagi. He's Reo, though, so Nagi's sure he does.

 

Nagi shifts in front of him, hands splayed too wide at Reo’s waist, fingers sliding lower until they rest heavy at the slope of his hips. Suddenly, he's a lot more aware of the soft stining of his back and the litany of kiss-marks sucked red and true in the shape of Reo's teeth and tongue against his skin. He can feel the ghost of last night in the minute ache of his body, the faint throbbing where Reo’s teeth had sunk too far in, in the split of his lips, the red welts along his back. Similarly, the red marks scattered across Reo’s collarbone, too, are proof enough that Nagi hadn’t been gentle, either. After all, Nagi had wanted to bite deep, to claim and keep, and Reo had let him. Reo always does.

 

Now, under the soft kitchen light, Reo looks both ruined and untouchable at once—every bruise a blinking badge that says mine, mine, mine—and Nagi can feel his mouth dry. It's not new, so Nagi isn't surprised. Reos had this effect on him since...forever, probably. 

 

Reo…” Nagi breathes, low and gravel-thick. His mouth finds the curve of Reo’s shoulder, brushing past damp locks of purple hair. He tries to think of something normal to say. “Still sore?” His hand brushes down the small of Reo's back. 

 

Reo’s laugh is sharp, bright and amused. “Obviously. You were like a dog in heat last night, treasure.” He glances up at Nagi through coy lashes, a teasing glint in his eye. “Your wife's poor, maidenly body can only take so much, Seishiro.”

 

Nagi flushes hot. The comparison makes something warm curl low in his gut, makes him want to shove Reo over the counter and hold him down just to prove he hasn’t hasnt taken quite enough yet. Or perhaps he wants to sink down to his knees, grab Reo's feet and beg for forgiveness. He isn't quite sure. All he knows is that he wants Reo, really, and so his arms tighten, pulling Reo flush against him (hips to chest, and beating hearts going thump-thump-thump against each other) until there’s no space left between them.

 

“Reo liked it, though,” Nagi mutters petulantly. For good measure, he mouths the underside of Reo's jaw, teeth catching skin that's already marked, nipping and then sucking until Reo gasps. “Reo always likes it rough.”

 

Reo shivers but doesn’t pull away. Nagi's glad he doesn't; doesn't know what he'd do if Reo did pull away from the pushy, childish parts of him. Or he does, but he doesn't really know if Reo would fancy the idea of being locked up, tied down. Nagi's tied him down enough already.

 

Before he can think anymore, Reo's hand comes up, stroking lazy circles over Nagi’s strong forearm, indulgent even as his breath stutters. “I like spoiling my sweet little treasure—my dearest puppy—when he's a good boy. That doesn’t mean I’ll let him hump me whenever he wants.”

 

“Mm. But I want Reo now, though.” Nagi noses along Reo’s throat, desperate, the words tumbling out raw and unfiltered. “Reo’s warm. Reo’s mine. Ah, wanna fuck Reo.”

 

Reo chuckles, the sound molten, and tilts his head to bare his throat further. Nagi takes the bait and bites. Reo lets out a breathless half-moan. “You’re shameless, Seishiro," Reo says. "Didn’t last night wear you out?”

 

“No,” Nagi says simply. His hips press forward, proof of exactly how not worn out he is, half-hard dick brushing against Reo's front. His palms are already wandering beneath Reo’s robe, brushing possessively over his ribs, sliding lower until his fingers curl against the sharp line of Reo's pelvis. “It's never enough.”

 

Reo closes his eyes, and Nagi knows he's savouring the way savoring the way Nagi clings. Nagi wonders why he likes the way Nagi still trembles like an overgrown hound begging for scraps. He's Reo's treasure—so starved, so desperate, and only ever for him—and always will be, until the end. Reo rolls his hips shallowly, and Nagi shivers at the friction.

 

“…You really are my good boy,” Reo murmurs, tugging Nagi’s hair until their mouths crash together, hungry and biting. He tastes of coffee, and Nagi swallows the bitters of it all because it's Reo. Unbidden, the promise between them entwines them together, entwines their tongues together. The feeling of Reo's hungry mouth licking into Nagi's feels an awful lot like promises that Nagi will follow wherever Reo leads, and Nagi answers with a yes, yes, yes, sucking on Reo's lips, because has been following wherever Reo leads, and he never intends to stop. 

 

When they pull back, Reo take a shallow breath that's not enough but dives back in, refusing to allow them a moment apart. Reo still tastes of coffee, but this time the bitterness is ruined almost instantly by the way Reo bites down on Nagi's lower lip and tugs, pulling a noise out of him that’s more needy than he wants to admit. The bitten-raw lip from last night splits its flimsy patchup, spilling Nagi's blood into the kids. Reo lets out a soft moan at the taste, and then Nagi’s hands are everywhere, up under the silk robe, dragging across Reo’s marked chest, fingers tracing the lines of bruises like he’s trying to redraw them deeper. Maybe, if he pressed hard enough, he can leave his thumbprints on Reo's bones. 

 

The counter digs into Reo’s hips as Nagi crowds him further against it, and Reo doesn't make a single sound of protest, yanking the drawn-taut invisible leash between them with his eyes alone. Nagi kisses him, softer this time, for good measure. 

 

“Seishiro,” Reo drawls, voice husky with laughter. “Ah— be gentle— god, you really don’t have an off switch, do you?”

 

Nagi’s lips drag over the column of his throat, wet and hot, nipping and sucking and mouthing at every patch of skin he can reach. “Don’t need one. Not with Reo.” His breath is shaking, his voice dropping to something rougher. “Well, Reo made me this way. Reo’s gotta take responsibility.”

 

Reo laughs, but it breaks into a gasp when Nagi nips at the hollow of his collarbone. “Irresponsible little mutt,” he chides, but his fingers curl in Nagi’s hair, pulling him closer instead of pushing away. “So desperate you’d take me on the kitchen counter?”

 

Nagi groans against his skin. “Yes. Right here. Please, Reo…” His hands have slipped, fingers tugging at the tie of Reo’s robe until it falls loose, spilling the silk apart to bare more of that beautiful, bite-stained body. The sight makes Nagi dizzy. Every bruise, every mark, making Reo's body a map of their devotion to each other. It's proof of last night, and temptation for right now.

 

“God, you look…” His voice falters, chest tight. “…ah, Reo's mine.”

 

Reo smirks, though his breath is already unsteady. “Always yours, Seishiro. That’s the problem, isn't it? You hardly know what to do with me once you’ve got me.”

 

“I know what to do,” Nagi counters, voice sharp with need as he presses their hips together. His erection grinds against Reo’s through the thin layers of fabric, shameless. “Wanna fuck Reo so bad. Wanna fill Reo up until he can’t think about anything else, please. Ah, wanna make a mess of Reo's pretty hole, too.”

 

The words make Reo’s knees weaken; he bites back a sound, covering it with another grin. “Like a dog,” he teases, but his hands are already guiding Nagi closer, tugging at the drawstring of his pants, at his waistband. “Who else could handle something like this, hmm? Seishiro, you're so cute, you know? My needy, obedient dog.”

 

Nagi whines, raw and broken, as Reo finally cups him through his sweats, squeezing just enough to make him buckle. His fingers tremble on Reo’s waist, digging in hard enough to bruise. Reo lets out a soft noise.

 

“Reo,” he pleads, kissing him again, sloppier this time, teeth clashing. “Please. Please, wanna be inside. Right now. Right here. Reo.”

 

Reo hums against his mouth, pretending to consider, even as his own arousal stirs hot, twitching with wet interest, between them. “On the counter it is, then,” he decides finally, pulling back just enough to glance at the polished marble surface. “If my treasure wants to rut into me like an animal, I may as well make it easy for him.”

 

Nagi’s breath hitches. His grip on Reo tightens, like if he lets go for even a second, the moment will disappear. “Love you,” he says, desperate and unpolished, like the words are burning out of him. “Love you, love you, love you—”

 

“I know,” Reo cuts in, threading his fingers through Nagi’s hair and yanking his head back to kiss him hard, bruising. “I love you too, Seishiro. So be a good boy, and entertain me first.”

 

The robe, already askew, is pooling at Reo's elbows as he lets Nagi lift him and set him down on the cold counter with reverence that doesn’t match his shaking need. Their mouths crash again, rough and messy, Nagi pawing at his lover like he’ll starve without him. Maybe he will. It's not like Nagi was alive before Reo. He can't imagine a life without Reo, so he puts his mouth to work for his boss.

 

Reo tips his head back, gasping as Nagi’s hands spread his legs open, as his hungry kisses scatter down his chest, over the purpled marks he left last night. Nagi's tongue laves over his collar, sucking at a bruise, before swirling around a pink nipple till it turns stiff, before moving lower still. Nagi’s hands tremble as he drags Reo’s briefs down in one rough yank, baring him completely to the cool air of the kitchen. He can’t breathe for a moment—because Reo’s body is still raw, still pliant. His puckered hole is pink and puffy, still raw from last night, gaping around nothing.

 

“Reo…” Nagi's voice cracks. His dick is pressing hot and desperate against the seam of his sweats, leaking, throbbing, demanding. “Reo, please.”

 

Reo just smirks through his heavy panting, eyes half-lidded, letting Nagi manhandle him without complaint. His long leg hooks over Nagi’s shoulder easily, deft fingers spreading himself open in a way that makes Nagi’s vision blur.

 

“Mm? Begging already, Seishiro?” Reo teases, though his tone is shaky, stretched taut.

 

Nagi ruts forward instinctively, his clothed length grinding over the twitch of Reo’s loosened hole, smearing wet and sticky across the inside of Nagi's underwear. The sensation makes him groan, guttural, his forehead pressing to Reo’s collarbone as he shudders.

 

“Please, please let me—” His words tumble over themselves, breathless, needy. His hips won’t stop moving, rubbing himself against that place like a starving thing. “Reo’s still soft—Reo’s perfect—need to fuck you, please, please.”

 

Reo exhales sharply, caught between laughter and a moan as Nagi drags the clothed head of his cock back and forth over his entrance, the barrier of fabric damp and obscene. His hand slips into Nagi’s hair, tugging his head back so he can look at his flushed, ruined expression.

 

“You’re pathetic, Seishiro,” Reo says sweetly, indulgent. “Grinding on me like some mutt in heat.” His nails scrape the back of Nagi’s neck, making him shiver. “But you’re my mutt. Isn’t that right?”

 

Yes,” Nagi gasps instantly, no hesitation. His hands squeeze Reo’s thighs, pressing his leg higher, folding him in half like he wants to crawl inside him and never leave. His voice is broken, begging, raw. “Yours, only yours, always yours— Reo, please, I can’t— I need to be inside you.”

 

Reo studies him for a beat, drinking in every ragged breath, every whimper, every desperate grind of Nagi’s hips. Then, with a slow, wicked smile, he slips his fingers under the waistband of Nagi’s sweats and briefs and tugs them down together.

 

“Go on, then,” Reo murmurs, stroking his cheek with mock tenderness. “Show me how badly you want me.”

 

Nagi all but sobs with relief as his cock springs free, flushed and dripping, and he presses it immediately against Reo’s raw, waiting entrance, rolling his hips in a shallow motion against Reo like he’ll die if he doesn’t get in. His whole body shakes with restraint, with need.

 

“Reo— please—” he chokes, rocking his hips shallowly, his leaking dick smearing precome over Reo's loosened rim. “Let me, let me fuck you— please let me—”

 

Reo arches against the counter, body already yielding, soft and ready from last night, and smiles—a master rewarding his most desperate pet.

 

“Alright, Seishiro,” he whispers, tugging him down for another bruising kiss, biting down harshly on Nagi's lower lip. Nagi tastes the iron tang of blood between them as Reo leans back and smiles, lips red with Nagis blood. “Fuck your wife.”

 

Nagi barely even hear the words properly, but that's all it takes for him to snap, shoving Reo’s leg higher over his shoulder, bending him in half on the countertop. His throbbing cock pushes forward and slides inside with hardly any resistance, Reo’s body still loose and welcoming from the night before.

 

The sensation rips a broken groan out of Nagi’s throat. He bottoms out in one smooth, desperate thrust, balls pressed flush to Reo’s ass, trembling all over.

 

Reo—” His voice cracks, choked and pleading. Nagi can’t stop kissing him, sloppily mouthing at his throat, his jaw, his swollen lips. “So warm inside— so perfect— mine, mine, mine—”

 

Reo laughs, low and breathless, nails dragging down Nagi’s back. “Ah, my treasure's pathetic,” he whispers, though his voice is wrecked with pleasure. “Can’t even last a morning without stuffing yourself inside me again…”

 

Nagi moans against his chest, his hips snapping up at Reo's words before he pulls out, feelings the drag of Reo's warm walls pulsing against him, before he shows back in again thoughtlessly. Nagi's rutting in frantic, sharp thrusts, the slap of skin against skin echoing in the once-quiet kitchen, obscene and unrelenting. His pace is mindless—animalistic, just like Reo said, Reo's always right—like he’s trying to mould Reo's insides around his cock.

 

“Can’t— Sorry, Reo, can’t help it,” Nagi pants, burying his face against Reo’s throat. His teeth scrape over bruised flesh, biting down until Reo gasps, moaning wantonly. “Reo’s too good— Reo’s everything— don’t ever wanna stop— ah, Reo—”

 

Reo tilts his head back, eyes fluttering shut, body rocking with every punishing thrust. He can feel how sloppy it is, how raw, how desperate—the wet drag inside him from last night’s ruin making every thrust loud and messy. “God, you really are my dog,” he groans, hole clenching tight around Nagi, intending to milk him dry. “Ah, you— oh—! there, yes, Seishiro— you're fucking into me like you’ll die without it— haaah—

 

Yes,” Nagi whimpers, his voice breaking. “Yes, Reo, yeshnn— your dog, only yours, always yours—” His thrusts grow rougher, deeper, pressing Reo into the counter hard, watching as his head lolls against the marble counter, beautiful purple hair spilling out over it's bright white surface.

 

Reo clings to him, one hand yanking sharply at his hair, the other clutching his shoulder hard enough to leave little red nail-shaped crescents in Nagi's skin. Reo's body is pliant, already undone, letting Nagi take and take and take. Every time Nagi slams into him, Reo gasps loudly, chest heaving with effort as he arches into it, indulgent, feeding every drop of Nagi's desperation.

 

Harder,” Reo commands, tugging Nagi's hair violently, pulling him closer. “Come on, Seishiro. Ahhghh— I can still talk, you know— fuck your owner properly.”

 

Nagi whines brokenly, hips snapping forward faster, harder, until the counter itself seems to shake under them. His whole body is on fire—sweat slicking his back, breath hitching ragged with every thrust. The heat in his gut builds sharp and unbearable, but he clings to Reo like drowning; he can’t come unless Reo tells him to.

 

“Reo— Reo, please— gonna cum— can I— please—”

 

Reo’s smile is molten, lips brushing his ear. His voice is raw, jerky as he whispers. “Do it, Seishiro. Mark me. Fill me up again. Ah— I'm all yours, my love. You're such a good boy, aren't you?"

 

The words shatter him. Nagi slams deep, sheathing his cock as deep as it can go inside Reo's warm heat, and chms, crying out against Reo’s throat as he spills inside him, body shaking violently. His thrusts turn frantic and messy, grinding in even as he empties himself, desperate to fuck his spend deep as possible into Reo.

 

Reo moans with him, head tipped back, fingers clutching his hair. The warmth floods through him, cum spilling out around Nagi’s cock in lewd, wet smears across his thighs and onto the countertop.

 

For long moments, there’s nothing but their ragged breathing, Nagi still rutting weakly inside, unwilling to pull out. His arms cage Reo close, trembling, sweaty, clinging like he’ll fall apart if he lets go.

 

“Good boy,” Reo finally murmurs, stroking the back of his neck, indulgent and smug. “You really can’t stop, can you?”

 

Nagi shakes his head against Reo’s chest, breath still broken, voice raw. “…Never. Don’t wanna stop. Reo’s mine. Forever.”

 

Reo smiles, kissing the crown of his head. “That’s right. Forever.”

 

Nagi slumps against him, still shuddering with the aftershocks, forehead pressed to Reo’s chest. His cock twitches weakly inside, buried deep, and he breathes out a ragged, “Reo… love you…” against spit-slick skin. He's already hardening again inside the slick heat of Reo, but whimpers softly, like a dog begging for another round.

 

For a heartbeat, Reo lets him have it. Lets him pant and tremble, lets him cling with all the fragility of something about to snap. His hand strokes the back of Nagi’s neck, deceptively tender.

 

But then Reo shifts his hips deliberately, grinding his own flushed length pressed between them against Nagi’s stomach, smearing precum over both their skin. His voice is sharp silk when he speaks.

 

“I’m not finished yet, Seishiro,” he hums. "You can't be done yet."

 

Nagi jolts, eyes blown wide, body already shaking from overstimulation. “Reo—”

 

You came,” Reo murmurs against his ear, nails dragging lightly down his back until Nagi arches with a whimper, “and I didn’t. What kind of dog forgets his owner?”

 

Nagi groans brokenly, hips twitching forward without thought. He’s still hard, still filling Reo up, nerves screaming from the sensitivity, but he can’t say no. Not when Reo’s voice is like that, not when his cock is pulsing against his belly, begging for release. Not when he's been a bad boy for his beloved boss.

 

Move, Seishiro," Reo commands.

 

Nagi doesn’t hesitate. His body obeys before his mind catches up, hips rutting forward again, cock dragging out of Reo’s swollen heat only to slam back in. The nerves of his over-sensitive dick flare with sensation, sending jolts of white-hot heat through Nagis body. The sensation makes him cry out, drool slipping from his lips as he buries his face in Reo’s chest, licking and biting frantically just to ground himself.

 

Hnn— Sei— good boy,” Reo praises, voice shaking with pleasure. His nails dig into Nagi’s back, raking hard enough to leave angry red trails. “Ahmmm— that’s it. Don’t you dare stop until I’ve finished.”

 

Nagi whines against his chest, slobbering kisses over every bruise he can reach, tongue dragging messily over skin. He sucks at Reo’s nipple, teeth grazing just enough to make Reo gasp, and thrusts through the unbearable overstimulation because Reo told him to. He sucks and pinches at Reo's chest, teasing the soft pink buds of Reo's nipples. Reo moans loudly, hips shifting up to meet Nagi's in a jerky movement. Nagi relishes the sight.

 

“Hurts— feels good— Reo, so good, ah—” His words are nonsense, muffled against skin as his hips piston mindlessly. His hands are iron on Reo’s thighs and waist, gripping so hard that purple marks will bloom there too. Reos skin shivers under his grip. Every thrust is punctuated by desperate moans, every grind an act of worship.

 

Reo throws his head back, chest heaving, as Nagi ruts into him like he’s lost control of everything but the need to obey. Precum smears hot across his belly with each movement, his cock throbbing painfully between them. He clutches Nagi’s hair, pulling his head back to watch his ruined expression.

 

“Look at you, ahhnnn—” Reo groans, eyes dark with heat, even as his eyes are hazy with pleasure. “Drooling— fuck, Seishiro, more— all over me— hahhhh— whining like a bitch in heat, but still you're fucking me exactly how I want. God, yesSeishiro—! You really were made for me, weren’t you?”

 

“Yes— yesyesyes—” Nagi babbles, voice breaking as his tongue lolls against Reo’s chest, spit glistening. He can’t stop licking, sucking, biting, as if clinging onto Reo with his mouth will keep him tethered to the world.

 

Reo’s breath hitches, his body clenching tight around Nagi’s cock as his orgasm builds sharp and relentless. “Ah— Almost there,” Reo grits, drool slicking down his chin, tugging Nagi’s hair so he’s forced to meet his gaze. “God, don't stop, Seishiro. You're so good, hnnyes, Seishiro, Seishiro, Sei— so close, make me come—”

 

Nagi dumbly nods his agreement, fucking him harder, every nerve lit with fire. His vision blurs, drool smeared all over his cheeks, but his hips never falter. His hand reaches up to yank at Reo's cock, smearing the stream of leaking hot precome over his slit—and that's it.

 

Reo finally tips over the edge, spilling hot between their bellies, crying out Nagi’s name like a prayer. And god, isn't Reo's voice so, so sweet like this? Loud, unbidden, wanton, just shy of breaking…Nagi nearly collapses hearing the sound. Still, he keeps moving even as his body begs for mercy because Reo hasn’t told him to stop. Nagi is already trembling on the edge, body frayed raw from overstimulation, but the way Reo’s body clenches down, soft rim fluttering around him—tight, pulsing, suffocating—rips the ground out from under him. He's overwhelmed by the way Reo clenches around him, by the sound of his cries, and the way Reo clings to him like he's the only thing that matters. Reos hole is warm and wet and sucking him in likes he's made for it, made for Reo, and Nagi can't keep it together anymore.

 

Reo—!” The name bursts out of him, wrecked, almost a sob. His vision whites out, stars bursting behind his eyelids as his cock throbs violently, spilling a second time deep inside. His hips jerk helplessly, rutting through it, grinding as if to carve himself into Reo’s body.

 

Maybe he's greedy, but who can blame him? It's Reo, and he will always want more. Even after the unbearable waves crash through him, leaving him weak and shaking, his body keeps rocking forward in a desperate, mindless rhythm. Reo’s legs are still hooked tight around his waist, keep him flush against him.

 

Nagi's mouth can’t form words anymore. Every sound he makes is Reo’s name, gasped, moaned, broken against Reo’s throat. Drool slicks his chin, his chest heaving as he shakes with the effort.

 

Reo, flushed and panting, rides out the last shudder of his orgasm with a soft little smile. His arms are wound tight around Nagi’s shoulders, hands clutching ar sweat-damp skin. He holds Nagi there, lets him keep moving as he whispers weakly, watching the way his treasure is undone beyond recognition.

 

“Good boy,” Reo murmurs finally, low and honey-sweet, his tone softer now. His fingers slip into Nagi’s hair, stroking back damp white curls. “You did so well for me, my Seishiro. My perfect boy.”

 

The praise makes Nagi whimper, broken and small. His body jerks again, still twitching inside Reo, but the tight knot around his chest begins to ease.

 

Shh,” Reo soothes, petting him like a worn-out puppy. “It’s enough, treasure. You can stop now.”

 

The words crash over Nagi like mercy. His hips falter, stutter once, then still completely, his whole body sagging forward until he’s slumped against Reo’s chest. He pants raggedly, clinging to him with shaking hands, forehead pressed into the curve of Reo’s neck.

 

“…Reo,” he whispers, barely audible, voice scraped raw.

 

“I know,” Reo hums, kissing the crown of his head, rocking him gently despite the mess between them. “I know, Seishiro. You did so well. You’re so good at being mine. I love you so much, you know. Love you,my baby.”

 

Nagi melts into the words, into the touch, utterly ruined but blissfully content, the praise seeping into his bones and making him feel all tingly and warm. Reos hands card gentle through his hair, untangling the sweat slick strands clinging to the circles of his forehead and cheek. He nuzzles happily against the warmth of Reo, fucked out.

 

Yeah, Nagi thinks, this is the life.
