Work Text:
throwing his bag down on his bed, jungkook sighs.
“joom,” he whispers, hopefully low enough that his roommate and best friend, namjoon, can’t hear his voice. “joom, where are you?”
he strips off his shirt as he putters around the room, pulling down the shades and turning on the overhead fan to keep himself from overheating, then kneels down in front of his wardrobe. “did you end up in here?” he mutters, pushing aside shoeboxes and random articles of clothing that have fallen off their hangers. his hand brushes against the smooth material of what he’s looking for, and he lets out a noise of triumph as he pulls the box closer to himself. “there you are,” he breathes out, lifting the lid of the box to reveal—
“joomie, you look just as good as ever,” jungkook says, smiling wide as he pulls the large silicone toy out from his collection. “it’s been a long day, my friend.”
jungkook tosses the dildo onto his comforter, placing the box on his dresser for easier access in case he gets the urge to use anything else from it. he pulls off the rest of his clothes, bending over his drawer to find his lube, naked as the day he was born. he’s debating following this part of his routine with putting on some music, maybe that playlist of lo-fi hip-hop that namjoon made for him, but he knows that the sultry beats picked out by his hyung will get him riled up much quicker than he wants tonight. the silence as his fingers curl around the bottle of slick is heavy, and he snorts in the direction of his rubbery toy. “no, joom, i know i said i’d try to find a new hookup, but namjoon hyung just held me captive in the living room for a half hour while he was sweaty and shirtless, so i don’t have time to find someone with a good enough stroke game on such short notice.”
stumbling over one of his boots, jungkook makes sure his door is shut, not wanting his roommate to barge in while he’s having private time. “you also cost me one hundred forty thousand won, joom, so you’re tonight’s hot date.” the sound of his phone going off draws his attention back across the room, his fingers falling away from the door’s lock, still in the same position it was when he came to this part of the room. picking up the device, he unlocks it to find a selfie from namjoon, his dimples creating little divots in his cheeks that are almost endearing enough to distract from how he’s still shirtless, the sweat at least having dried by now.
[namu namu namu 9:32 pm]
look at how broad my shoulders look, koo. your workout plan really does work
jungkook chokes on his own spit as he tries to absorb every inch of the photo, zooming in on the veritable field of tanned skin and the muscle bulging under it. his already chubbing-up dick makes itself known, giving an impressive twitch that he can’t help but palm at, still focused on his hyung. an email comes in, then, and the offer for discount body spray from some store he’s never signed a mailing list for ends up snapping him back to reality, the image of namjoon no longer enough to keep him worked up on its own. he gives his dick one last squeeze, glancing sidelong at the purple dildo laying on the bed, furrowing his brows as the offending hunk of silicone seems to be appraising his actions.
“don’t judge me, joom, you’re literally a sex toy.”
he, understandably, gets no response, but he’s reaching a point where everything is almost entirely set up, so he dims the lights and climbs onto his bed. squeezing lube in his cupped palm, he grabs the dildo to get it slicked up, mind wandering back and forth between images of his crush and thoughts of disappointment that he doesn’t have a toy that shoots the cum-lube he spent way too much money on. he mourns this loss every time he has this specific flavor of alone time, but it doesn’t ever get better; he hadn’t read the full product description when purchasing his first Bad Dragon—the one he’s currently setting up to rest right under his rear, the tip flirting with the crease of his ass cheeks—and because he didn’t read the description well enough, a false assumption he’d had about all Bad Dragon toys being able to accompany the lube shooter led to him purchasing the highest quality setup the store had. he’d eyed the images of the silky white synthetic come and what looked like a cartoon syringe of comically large proportions, mouth watering at the promise of living out some of his biggest fantasies.
Glyph, the toy he’d purchased that he immediately renamed after his hunk of a roommate, had arrived within the month, and when he’d pulled everything out to find that he couldn’t fuck himself full of come, couldn’t send shot after shot of lube into his body in an attempt to become come-drunk, he’d almost cried in their front hallway. namjoon’s appearance had stopped the waterworks from flowing, getting jungkook to hastily shove the colorful toy and its accoutrements back into the box just in time to dash to his room.
“well, at least you’re big,” he sighs out, bringing his brain back to the current moment and letting the slightly pointed tip of joom’s head push between his ass cheeks to prod at his hole. he pulls away a little bit, just enough that the toy retreats from its poking, but doesn’t dislodge from where it’s nestled between the muscles of his ass, then sticks his fingers in the gap, rubbing lube along the pucker of his hole, not penetrating, but simply making sure the slide will be smooth.
taking a deep breath, jungkook makes sure the tip of the toy is pushing into him, then plants his hands on the bed in front of him, fingers curling into the blanket as his head falls forward to hang between his shoulders. the toy nudges in more as he sits back on it, slowly, drawing a whine from him. the burn from his lack of prep is unavoidable, but jungkook revels in it, loves how it feels to be stretched out like this because of the dick and not because of his fingers. he loves the little bit of pain, groaning low in his throat when he gets to what he thinks is the halfway point.
“shit!” he hears from outside of his room, the word having immediately followed the crash of something hitting the deck. it makes him pause, thigh muscles straining to keep him in a single place and trying hard to avoid the temptation to start outright riding the portion of the toy already inside of him. the stretch still feels amazing, and the tease of more that he knows is coming is overwhelming, so the more he waits in silence—not hearing anything else from namjoon—the more he gives in to the urge to keep sinking onto the dildo.
inch by inch, jungkook lets his body engulf the toy, gasping in pleasure when the tip of it brushes against his prostate, quickly bypassing the spot and going deeper, the bulging muscle definition of the toy’s molding bumping against the gland instead. he’s completely forgotten about pretending like he’s not fucking himself while his roommate is home by the time he reaches the base of the toy, rim stretched wide as his rear end rests on the blanket. the noise he makes as he circles his hips around is low and guttural, the sheer pleasure of being stuffed so full seeping into every crevice of his mind and body.
he basks in the stretch for a little while longer, pleased to hear silence from his clumsy roommate; if namjoon isn’t making noise, it means he’s focused on something and won’t be interrupting jungkook anytime soon.
he raises up as much as he can, the tiny bumps around the toy’s head teasing at his sensitive rim. “oh, fuck,” he groans, bouncing in tiny movements just to feel the uneven surface, only letting his ass take the entire dildo after he’s driven himself to desperation with his own teasing. he doesn’t touch his dick, not yet, not when he knows he has the time to draw this entire experience out.
the friction of the toy inside of him becomes dry much more quickly than jungkook would prefer, but when he starts searching the bed for the bottle of lube, he comes up empty-handed. sighing, he climbs off the dildo, knowing that the cum-lube and accompanying equipment are in the toy box sitting on his dresser, and it take minimal effort to get it out, injecting a small amount right into his already slightly-gaping asshole before he plops back down onto joom.
a buzzing on the covers beside him filters into jungkook’s ear, another text from namjoon arriving and lighting up the screen. he doesn’t stop his movements as he unlocks the phone, body raising up and hips rotating in figure eights when he drops back down.
[namu namu namu 10:00 pm]
hey koo, does this look good?
jungkook waits for the photo to arrive, and when it loads, he chokes out a hoarse groan, leaning his weight on a shoulder so he can use his other arm to grip the base of the dildo, working as hard as he can to fuck himself with it. he keeps his phone open, staring at the picture that namjoon had sent of himself, a tight short sleeve shirt on, form fitting and drawing attention to the man’s pecs. the rumble of a new message isn’t what jungkook wants, not when his hyung wants a response and all he cares about is coming at least once this evening.
[namu namu namu 10:10 pm]
bun? is everything okay? you usually don’t take so long to respond :(
trying to figure out how to respond is taxing his strung out brain, so jungkook slows down his motions, trying to calculate the easiest way to answer without stopping his alone time entirely. using the hand attached to the arm he’s resting on, jungkook cobbles together a message, hitting send and locking the device, hoping that his quick ‘sorry hyung, i’m busy’ will be enough to dissuade his roommate from texting further.
he shifts to put the phone back down, losing his balance in the process and falling onto his back. groaning at the loss of a perfectly good position for fucking himself, he sits upright once more, kneeling over the dildo and sinking back down like he hadn't moved in the first place, getting right back into riding the toy like his life depends on it.
the sound of loud footsteps in the hallway is almost enough to get jungkook to stop, but he’s creeping closer to an orgasm so he keeps going, figuring namjoon will move on when he gets no response to his inevitable knocking.
“joom,” he moans out, the angle of his thrusts jabbing right at his prostate.
a commotion from his doorway occurs, then, and it all happens so quickly, jungkook finds himself too stunned to respond in any logical way, the only noise he’s able to emit being a squeak.
“are you—” namjoon asks, tone frantic, but he seems to lose momentum when he sees that jungkook is naked and hard as a rock, a good portion of a dildo shoved in his ass where he's frozen halfway down it.
“why are you here?” jungkook asks, so baffled that he can’t bring himself to be embarrassed or angry.
“you said my name!” namjoon cries out, gesturing wildly, and jungkook realizes that his roommate must have heard him being desperate for a fucking sex toy, something he truly hopes that his hyung hasn’t pieced together yet.
with a shake of the head, hoping namjoon’s trust in him alone will be enough to get away with it, jungkook lies. “no, i didn’t say your name, joon hyung.” jungkook is hoping that he can talk his way out of this mess, but his thighs decide to choose that moment to lose strength. he gets through the first half of his sentence, “but the door was locked, how—” before his body just drops, asshole swallowing up the rest of the dildo, the raw pleasure making him throw his head back as he lets out a loud cry.
“it,” namjoon says, his voice distant in the roar that is jungkook’s brain. “it wasn’t—”
panting, jungkook lifts the weight of his own head so he can look at his hyung, his eyes running from the older’s shocked expression, down past his broad shoulders and thighs that are being gripped by the fabric of his sweats, to his bare feet. he doesn’t even register what he saw, at first, but once his brain clicks back online, he realizes that the space between namjoon’s abs and his gorgeous thighs contained a bulge that jungkook doesn’t think he’s ever seen his hyung sporting before.
“hyung?” he says softly, still panting from the stimulation from the toy alongside the sheer elation he’s feeling at the sight of what is undeniably his crush’s erection.
“i—”
when it doesn’t seem like namjoon has anything else to say, jungkook meets his eyes, his own wide in curiosity. “why are you in here?”
“you said you were hurt!” namjoon says, exasperated, a hand dropping toward his crotch before he seemingly catches himself, stopping the appendage from making contact.
“i said i was busy?” jungkook replies, confused. it takes a second to come to a conclusion, but once he does, he curses while glaring at his phone. “fucking autocorrect.”
namjoon chokes, and it draws jungkook’s eyes once more; he manages to keep his gaze on his hyung’s face for a moment, but the pull to look at the man’s dick is too strong, and he stares intently at it.
he can’t help how his hips are subconsciously making little movements, grinding down on joom as he observes namjoon’s cock. the man is massive, but not in the way that he’s slept with guys who have been hung, no. jungkook is a certifiable Size Queen™ and he’s never seen a dick this big; it looks long—the fabric around namjoon’s thigh is tenting outward much lower than jungkook would’ve expected—but also thicker, the kind of thick that looks like four dildos, taped together side by side.
“i should—”
“why are you—”
they both stop speaking when they realize they’re talking at the same time, but whereas namjoon just waits patiently, jungkook is itching to continue his question. “why are you so big? i have to be seeing things, hyung.”
namjoon moans, the sound startling jungkook and going straight to where his dick is bobbing in the air, hips lifting enough to get a few thrusts from the toy before he settles once more, swallowing the saliva that’s pooled in his mouth. his mind is going haywire from the fact that the love of his life is just casually watching him get off, not even attempting to leave the room.
“nope, not,” namjoon swallows, finally letting his hand come down to palm at himself, and jungkook’s suspicions are confirmed when he drags his hand all the way down his thigh to where jungkook now realizes the head of his cock lies. “not seeing things, koo.”
“lemme see,” comes out of jungkook’s mouth before he can stop himself, freezing in place as he realizes he’s likely crossed a boundary that even he isn’t lax about. working to figure out how to phrase his apology, he doesn’t even realize namjoon’s nodding, fingers slipping under the waistband of his sweats and tugging, the gray fabric bunching up around mid thigh. “oh god, you’re—”
“a dragon, yeah,” namjoon finishes for him, but jungkook is too caught up in looking at the heavy weight of namjoon’s cock. it’s bulging and huge, more reminiscent of the toy currently sitting in his ass than jungkook ever would have presumed a cock to be. it’s not purple, a fact jungkook is relieved about, but otherwise he’s hard pressed to come up with an explanation that isn’t ‘something not human’. namjoon’s response registers, then, and he lets himself ride joom a few times before speaking.
“a dragon?” at namjoon’s nod, he forces himself to stop gaping and actually figure this out. “i just figured you were hiding a pornstar dick, but this is even more surprising, hyung.” the older sheepishly runs a hand along the back of his head, smile apologetic in a way that jungkook wishes it wasn’t. “wait, hyung. dragons aren’t real, though.”
he gets a snort in return, namjoon gesturing grandly at his monster of a cock and how it’s leaking precome steadily. “tell that to my anatomy and the hoard of books all over the apartment.”
the library they’ve somehow ended up collecting makes a lot more sense as dragon’s hoard, but that still doesn’t explain anything else about this situation. “but i’ve met your parents, hyung.”
“what does that have to do with—”
“wouldn’t they have looked like dragons?”
he gets a snort in response. “...koo. if i don’t look like a dragon, why would my parents?”
jungkook only then realizes how much closer namjoon has crept, and when he puts in the effort to think long and hard about what other signs he’s missed, namjoon playfully pushes at his shoulder, laughing fondly at the younger’s concentration. the movement rocks jungkook back, though, and when his torso falls on the bed behind him, the toy pops out, standing proud on the mattress between his spread thighs. he lets out a dissatisfied groan, not happy that he’s no longer full, but namjoon’s gasp is more important.
“wait, that’s,” namjoon says, trailing off, and jungkook realizes he’s going to have to find a way to admit that his hyung isn’t wrong, that the toy he’s been cockwarming this entire time is actually a dead ringer for what namjoon’s apparently been packing this whole time.
“um, yeah,” jungkook says quietly, fingers itching to either touch his hyung or get the toy back inside of himself, but his plans get put on pause when namjoon’s reaction to finding out that jungkook owns a dildo that looks like his dick, is that said dick plumps up even more, somehow. the implication that namjoon’s not even at his largest is mind blowing and jungkook wants it inside of him so badly, but he can’t just ask, it's not that easy.
jungkook doesn’t end up needing to broach the topic, because namjoon seems unable to hold back, hand covering a portion of his dick and stroking up and down twice before stopping. as he pulls away, leaving jungkook to gape, tongue lolling out of his mouth, he reveals a bulge that jungkook hadn’t been able to see past namjoon’s arm. right at the base of his cock, jungkook realizes, is what looks to be a knot.
swallowing, jungkook gestures at it. “is that—”
namjoon follows his gaze, then sighs. “yeah, it’s a knot.”
“but.” he has to force away the mental images of being knotted, something he’s not proud to say he’s really into. “but i thought werewolves were the creatures with knots.”
“dragons have them, too.”
“namjoon hyung, that wasn’t something covered in Dragonology: The Complete Book Of Dragons.”
namjoon bursts into laughter. “are you talking about that kids book series you’ve ranted to jimin about way more times than i can count?”
“i’ve read it cover to cover!”
“for your kink?” the smile on namjoon’s face is purely teasing, by now.
“no! i’ve just,” jungkook goes quieter, knowing that he’s giving away more about his feelings than he’d care to admit, considering it should be an innocuous statement. “i’ve always liked dragons.”
namjoon cups his cheek, pulling his face up so they can look at each other, and jungkook gasps when he breathes out a soft, “sweetheart.”
“why didn’t i ever hear about the knots?” jungkook cuts him off, hoping to deter namjoon from digging into jungkook’s very romantic feelings for him.
“dragons are heavily misunderstood, kook-ah. people in the past just kinda made shit up, and once it stuck, we weren’t going to correct them, not when it meant we’d go undetected much easier.”
jungkook nods, chin still held in namjoon’s grip. “that makes sense. but knots?”
“it makes breeding easier, baby.”
he can’t help the breath he draws in at the pet name, can’t help how his hand flies to his dick to get even just a smidgen of friction. “hyung,” he sighs out as his fingers make contact, pure adrenaline rushing through him at everything happening, from the touch of his own hand, to the touch from his hyung, to the simple fact that it’s all happening at once and namjoon isn’t turning to leave.
“you’ve always liked dragons? or did you just like me?”
“both, but i especially like you,” he whispers, whining when namjoon presses a finger between his lips, letting jungkook suck on it.
“good boy,” he gets in response, and any doubt he could’ve had about this being one sided goes out the window when namjoon removes his fingers in order to press a soft kiss to jungkook’s parted lips. “always so good for me.”
“hyung—”
“gonna let hyung take care of you? treat you like you deserve to be treated, bun?” at jungkook’s nod, namjoon seems to get even more focused. “can hyung take you out later? go on a date and shower you with the affection you deserve?” jungkook whines, pressing their lips together once more, letting his tongue drag along namjoon’s plump lips, savoring the sensation of getting to experience this for the first time. “c’mon, baby, let’s get you stuffed back up again.”
jungkook nods, excited, and lets namjoon guide him so he’s sitting upright, sighing happily as he lays gentle fingers on jungkook’s dripping dick. he groans at one point and it makes the younger’s dick bob, amping up the sexual tension and leading namjoon to get the toy positioned so jungkook can once more sink down onto it. they both moan as he goes back to resting on the bed, the slick sounds of it entering jungkook’s body thrilling in the quiet of the room.
“i can’t believe you ended up with a toy that matches my dick.”
he snorts at namjoon. “it wasn’t intentional, i promise.” namjoon helps him sit up again, assisting jungkook in riding joom. “but the knowledge of what you’re packing might’ve made me purchase joom earlier than i had, if i'd known.”
“joom?”
he hadn’t even realized he’d let loose the name of his dildo, but hearing the word spill from namjoon’s lips makes his cheeks flush. “um. it’s what i named the toy.”
namjoon gapes, eyes wide and cheeks tinged pink. “is that what you were saying before i came in?” jungkook has to think back, but he nods when he realizes what the earlier miscommunication was. “did you really name a dragon dildo after me?”
“had to get off somehow when you were extra hot or sweet,” jungkook defends, but his admission seems to appease namjoon, who leans in for more kisses, not protesting when jungkook wraps both of his hands around the older’s dick, barely holding back a whine when he realizes how difficult the task is, with how thick namjoon is. “hyung, can i suck you off?”
namjoon gasps at the question, pulling away and standing up. jungkook is worried he messed up, is picturing namjoon walking off and it kills him inside, but his hyung just pulls down his sweats the rest of the way, tugging off his top as well to leave him completely naked. the size of his cock looks even more massive like this, sprouting out of a bed of neatly groomed pubic hair and looking like every wild sex dream jungkook’s ever had. “gonna keep playing with your toy while you do?” he asks, and jungkook nods eagerly, making grabby hands to get namjoon to come closer so he won’t have to abandon his perch on joom.
dropping his jaw, jungkook looks up at namjoon, hoping that the picture he’s painting will be tempting enough to get the girth of his hyung’s cock pushing into his mouth. the older traces lines on jungkook’s face with his fingers, making his eyes flutter closed in satisfaction, so when there’s suddenly the spongy head of a dick resting on his tongue, he startles, eyes snapping back open.
jungkook doesn’t waste any time, letting his lips wrap around the head, suckling at it in a way that feels almost too natural, like he could get lost in the motions without realizing it, if allowed. a hand gently cupping the back of his head pulls him back into his own mind, though, and he starts working to get his hyung’s length in his throat.
“be careful, baby,” namjoon grunts out from above him, but he just feels pushed to prove he can do it, swallowing down even more of namjoon’s dick until he’s pressing at the softness of the back of his throat. he pulls off just to slide forward without any preamble, and only pauses when he realizes namjoon is actively fighting off the urge to control his movements.
pulling away entirely, jungkook gasps for breath, already feeling fucked out from a handful of thrusts into his mouth. “c’mon, hyung, just use me.”
“what?” namjoon asks, looking concerned, but jungkook just grabs at his hands, placing them on his head.
“use me. fuck my face. i just want to feel owned by you, joonie hyung.”
a dark look steels over namjoon’s face, tone tight with arousal when he tells jungkook to pinch him if it’s too much, his massive dick looming right in front of jungkook’s face. “play with your toy, then, sweetheart.” he gets jungkook to open wide once more, than speaks as he’s sliding back into the wet heat of the younger’s mouth. “play with your toy and i’ll play with mine.”
jungkook’s cock twitches, his hips moving as he bucks as much as possible, allowing for the dildo to rub along his rim while stimulating his prostate once more. he moves in the same way again, hoping to recreate the sensations, and when he succeeds, he keeps the actions up, riding the toy while namjoon abuses his throat.
he thinks he’s getting close, but before he can ponder on it, namjoon is dragging him off his dick, watching with intense eyes as jungkook gasps for breath, hips still not stopping their grinding. “can i fuck you?”
jungkook keens, pushing namjoon’s hands away and climbing onto his hands and knees, presenting his already open hole for namjoon to take. “want it so badly, hyung.”
the bed depresses as namjoon crawls over to him, wasting no time to squirt an obscene amount of lube straight into jungkook’s asshole. he turns his head as he gasps, trying to figure out why his hyung hasn’t commented on the lube shooter when he sees that namjoon's managed to find the missing bottle of normal lube. keeping his mouth shut on the topic, he moans when namjoon shoves in three of his fingers right away, crooking them inside of his hole.
“gonna get you all ready for me, baby. you’ve already prepared so well, but hyung is bigger than that measly toy you have.” jungkook pushes back against the invading fingers, trying to be encouraging so namjoon doesn’t stop his assault on jungkook’s senses.
after a handful of minutes and some teasing at inserting his thumb as well as the four fingers already inside of jungkook’s body, namjoon pulls out, slicking up his dick loudly in a way that calms jungkook’s nerves. he’s going to get fucked, soon, and by the one person he’s wanted it from the most. “please,” he whispers, getting impatient while namjoon does his thing, realizing that the more prep namjoon does, the less sting he’ll feel and that’s the opposite of what he wants. “please, no more lube, hyung. wanna feel you forcing yourself inside, please.”
“you’re gonna need it for my knot, bunny,” namjoon says softly, and the reminder of his imminent knotting just makes jungkook want even more.
“then lube up just the knot, i don’t care, hyung, i just need you in me now.”
he gets a laugh for his begging, then namjoon pushes just the head of his cock against jungkook’s rim as he chuckles. “impatient, aren’t you, baby?”
jungkook doesn’t even respond, just pushes his hips backwards, managing to get another inch of dick inside of him, the stretch exquisite. namjoon’s hands grip his hips, though, and stop him in place and the sudden denial makes an indignant whine leave jungkook.
“where are your manners?”
“hyung!” he cries out, scandalized.
“you want my dick, baby bun, you’ve gotta ask nicely.”
jungkook grumbles out a ‘please’ in response, hoping that it’ll be enough to hurry things along. it’s not like he doesn’t like being polite for his hyung, but he’s being pushed to an edge where he’s feeling nothing more than greed, for both namjoon’s dick and his attention. it’s apparently not enough, for namjoon pulls out instead.
“no!” he yells, frustration coursing through his veins.
“say please or you get nothing,” namjoon chides, amusement clear in his voice and it just makes jungkook feel even smaller.
“please!” he says this time, loud enough that he thinks the tenants downstairs might've heard, but he’s not stupid; he knows that if namjoon won’t take his hedging once, the only path to getting reamed is through listening to what he’s told to do.
“good boy,” namjoon coos, pushing his cock back into jungkook’s ass even as he’s speaking. jungkook’s jaw drops, hands clutching the blanket and forehead mere inches from the bed; namjoon’s dick feels even more massive than it looks, the push of it as it’s forced inside of him the perfect mix of satisfying and aching. “taking me so well, jungkookie.”
any attempt to respond gets thrown out the window when jungkook tries to speak, a distorted groan coming out instead as namjoon presses against his prostate, not slowing his journey to sheath his entire dick in one inward thrust.
it feels neverending in the best way, but eventually, namjoon’s hips are pressed to jungkook’s ass. “god, i can’t believe you took all of me, koo. must’ve been training for hyung, weren’t you?”
jungkook wasn’t, but now he wishes he had been, the thought of having been this open because he wanted to appease his hyung hotter than he would’ve imagined. he nods, knowing that’s what namjoon wants to hear, and at his agreement, namjoon starts his journey back out. the bulges of his dick stretch jungkook’s rim, and the almost randomized stretch feels like heaven, something jungkook knew he liked on his toy, but that he didn’t realize would be ten times better on a flesh and blood cock.
namjoon’s fingers press into his hips as he holds tight, hard enough that he hopes bruises get left, a nice little reminder of their first time. his attention moves from there to how warm everything is, less like they’ve built up a sweat and more like namjoon is emitting more heat than normal. “hyung? are you too hot?”
“huh?”
the fact that his thrusting doesn’t slow down at all makes it harder for jungkook to talk, most of his attention on the delicious drag of namjoon’s dick into and then out of his needy asshole. “you’re so warm, hyung. are you okay?”
“oh,” namjoon says, sounding like he understands suddenly. “i run hot, kookie, i’m a dragon, remember?”
that would explain the sudden increase in wetness on each pump of namjoon’s hips, that they’re sweating more from the heat pouring off namjoon’s body. he doesn’t even realize he’s said this thought aloud, though, until namjoon finally slows down, his grip going loose and making jungkook look over his shoulder in a panic.
“what’s wrong, hyung?”
namjoon looks shy all of a sudden, and jungkook has no idea why. maybe being called sweaty embarrassed him?
“that’s,” he says, and jungkook listens with bated breath, ready to apologize profusely, already starting the process of shoving all of his horniness away in order to be the person namjoon deserves and not just his cock hungry self. “that’s not sweat. it’s precome, kookie. i’m sorry if that’s weird.”
jungkook processes this, trying to figure out what’s weird about it. it’s a slightly abnormal amount of precome, considering he’s never slept with someone who didn’t need to reapply lube because they instead produced a fair deal of it naturally, but it’s still not that unusual. his confusion must be obvious, because namjoon sheepishly continues.
“there’s a lot of precome because my body is trying to prepare you for my knot, and for all of the come i’ll fill you with. it’s a way to help make conditions perfect so our mating takes.” jungkook is silent, blood rushing through his veins and pounding loud in his ears, the words coming from namjoon like an aphrodisiac injected straight into him. “not that it would actually happen! i can’t breed you, not when you’re—”
“hyung will breed me?” jungkook butts in, dazed, unable to keep the words inside. “fill me up and let me carry his baby?”
namjoon is silent, but his breathing has become heavier, his grip tightening once more, and suddenly he’s shoving back inside at full speed, pulling a scream from jungkook.
“you want that, baby? wanna be knocked up by hyung?”
jungkook keens, nodding as he reaches a hand down to press against his lower stomach, imagining it distending to accommodate everything namjoon can give him. “hyung,” he whines, sobbing out a pleased cry when namjoon winds a hand around to link their fingers together, right over his abdomen.
“gonna knot you, make sure it all stays in, then when you’re finally relaxed, gonna add more to you. maybe it’ll stick if i keep pumping you full of my seed.”
“please!” jungkook cries, and maybe his need is enough to push namjoon along, or maybe they were both already so close to the edge it was inevitable anyway, but suddenly namjoon is stilling, pushing forward and working to get a much larger mass inside of jungkook’s asshole.
“stay still, baby, gonna have to get my knot in if you want to be full.”
jungkook tries his hardest to be calm, but everything happening is getting to him in all the best ways, and when namjoon gives a final push and his knot pops inside, stretching jungkook’s rim beyond anything he’s ever experienced, jungkook comes all over the blanket underneath himself.
namjoon moans, come leaving his dick in such large quantities, jungkook can actually feel it. he touches his stomach once more, awed that he can feel it filling up, a small paunch forming from the load after load namjoon is providing for him.
“god, baby, you did so good. made hyung feel amazing,” namjoon breathes out, leaning forward to nuzzle along jungkook’s back. “did you enjoy yourself?”
jungkook hums happily, still amazed that namjoon isn’t done. his arousal is fading slowly, but it’s leaving a feeling of content in its wake as he keeps getting pumped full.
eventually, namjoon’s hips stop rolling, and jungkook just barely manages to get them rolled onto their sides before namjoon goes boneless. “ah!” he cries out, and jungkook is suddenly on alert, worried something is wrong with his hyung. “what the actual—”
jungkook looks over his shoulder to see namjoon holding up the lube shooter, apparently having landed right on the hard plastic of it. “oh, sorry hyung, i didn’t know that ended up there.”
“is this what i think it is?”
“if you’re imagining ‘thing kook uses to fuel his breeding kink’ you’d be correct.”
“i—”
“it’s basically junk now, anyway, you can chuck it on the floor to be dealt with later.”
namjoon just stares at him, confusion all over his face. jungkook is expecting maybe a question about the breeding kink, or maybe about how weird it is, despite them both having just gotten off on it together, but instead namjoon just sounds concerned about waste when his rebuttal is, “but this looks brand new!”
jungkook snorts. “it basically is, but it’s not like i could get it connected to joom ever, considering the model of dildo joom is.” namjoon looks at him like he’s nuts, and it makes jungkook giggle. “besides, why the hell would i wanna use that thing when i’ve got you on call now whenever i wanna be knotted and knocked up?”
namjoon splutters and jungkook just grins, maneuvering so he can place a kiss on his hyung’s lips. when he pulls back, namjoon just seems fond, if slightly exasperated by jungkook’s antics.
“and who’s to say that i’d want to try that kink again?” namjoon says, playful tone putting jungkook at ease.
clenching his inner muscles down around namjoon’s now-deflated dick, jungkook groans at the fullness that hasn’t gone away, his own dick putting in the effort to get hard once more. “the fact that i don’t think the mating took this time, and that i know how to read your expressions, hyung. you were just as into that as i was, and you know it.”
it only takes jungkook wriggling his hips backwards once for namjoon to let out a low grumbling noise, pulling out just long enough to roll jungkook flat onto his stomach as he plunges back inside the younger’s loose hole. peppering kisses along his shoulderblades, namjoon seems to bask in jungkook’s gasps of pleasure as he calls jungkook a needy little thing.
bidding a good riddance to joom, jungkook just holds on tight and lets the love of his life fuck him brainless once more.
