Choi Beomgyu has a big mouth. A loud one. He uses it every second he’s awake- complaining, shouting, laughing too hard at his own jokes, and barking like some rabid mutt when he’s riled up. He smacks his lips while chewing, sucks on straws until they disintegrate, and licks his teeth when he’s thinking. Beomgyu’s mouth is always moving, always restless, like it has a mind of its own.
It’s a problem. A fucking problem.
Because no matter how hard he tries- chewing gum until his jaw aches, biting pens, sucking on ice cubes till his lips go numb- he can’t shut it off. It messes with his routine, his focus, his concentration. His instructors complain. His members complain. Hell, he complains. Beomgyu tried to hide this insufferable oral fixation from the others, but they eventually figured it out. They didn’t judge him, but no one really understood how bad it was.
Soobin tried to help by buying a jar of lollipops, offering them to Beomgyu only when he truly needed it.Yeonjun gave him a container full of bubblegum, which Beomgyu shares because if given the choice, he would devour it all in one day, which is obviously bad for his health. Taehyun is a bit bolder- he gifted Beomgyu a customized pacifier, emerald green with jewels spelling out his name.
Though embarrassed, Beomgyu thanked him with a tight hug and promised to use it at home. All the members try to help except one: Huening Kai. The so-called “angel” of the group, their cute maknae who squeals and laughs like a dolphin, doesn’t offer sweets or toys. Instead, he offers a different kind of solution- with that stupidly pretty face and that voice that makes Beomgyu’s teeth grind.
~~~
“Hyung, are you alright?” Beomgyu stops chewing his lip and glances at Taehyun, who’s looking at him with concern.
Damn- was he that obvious?
“You can have gum if you want. I know it helps you concentrate. Your lips look like they’ve been stung by a bee.” Beomgyu pouts and folds his arms, annoyed and a little embarrassed. Of course Taehyun noticed. “‘M fine.” Beomgyu stares at his own reflection, worrying his lip raw. He wants the gum, his mouth is aching for it. But he doesn’t want to trouble anyone, distracting them by chewing too loud.
So Beomgyu settles to biting what he has closest to him- his lips. Their English teacher drones on about something he can’t understand. Subject-verb agreement? Whatever. He’s not listening. Beomgyu feels his lips throb, a numbing, stinging pain that makes him grimace. “Huening-ah, why don’t you start a conversation with Beomgyu in English? If you both do well, everyone can go home early.” Their instructor smiles warmly. Beomgyu’s chest tightens. He doesn’t want to mess this up.
He wants to go home, curl up with his pacifier, or just eat. Beomgyu’s tongue pushes nervously against his cheek. Then he looks at Huening Kai- hair soft and wavy, eyes glinting mischievously, lips curling into that smirk that always spells trouble. “Hello there, Beomgyu. How was your day?” Kai smiles, extending a hand. Beomgyu shakes it awkwardly, fumbling for a response.
He feels Taehyun’s concerned stare boring holes on his back. “Good. I just finished practice. How about you?” His words sound stiff, rehearsed. Beomgyu hopes that damn internet list of “40 Basic English Phrases” didn’t screw him over. The teacher chuckles. “That was good! A little bland, but decent. Why not stay and practice together? The others can go home. Only if you’d like to, of course.” Beomgyu wants to scream. He pleads with his eyes.
“Um, seonsaengnim. I actually-” But the maknae smirks, sliding an arm over his shoulders. The members were already outside, talking about what they should eat for dinner. Taehyun gives Kai a nod and leaves with the hyungs. “I'll teach him. Beomgyu-hyungie is really shy when someone’s watching, so I’ll supervise.” Kai says sweetly. “Can we use this studio alone? I’ll lock the door so no one interrupts.” Their teacher beams, patting him in the back. “Of course! No problem. You’re an angel, Kai.”
Oh, you little shit.
Beomgyu’s eye twitches in annoyance, a hundred violent thoughts flashing in his head. The instuctor leaves, hanging a “Do Not Disturb” sign on the knob. As soon as the door clicks shut, Kai bounces to lock it, clearly delighted. Beomgyu’s lips throb, red and sore, his mouth salivating for something- anything; to soothe his unbearable oral fixation.
“You brat, I’m going to fucking-”
Kai laughs, pushing him onto the couch, hovering above him with a mischievous glint. “Hyung, don’t forget our other lesson. You still haven’t taught me how to kiss with teeth.” He giggles, looking like a predator admiring its prey. Yes, both of them had been participating in “Kissing Lessons.” It started when a shy Huening Kai confessed that he hadn't kissed someone before.
Beomgyu told him that it wasn't a big deal. It's not like they were allowed to date after all. Soobin agreed, and Yeonjun, being the mother hen that he is, told Kai to not even think of doing it. The younger male gave him the widest and cutest puppy eyes he could muster, and Beomgyu felt his breath get knocked out of his lungs.
"But still! I want to learn how to kiss. You know how, right, hyung? I overheard you talking about it with Soobinie-hyung and Yeonjunnie-hyung when you were drunk. That's not right. I'm the only one without experience! Even Tyun did it already. Please?" Beomgyu remembers it vividly. His pout, the frustration in his voice, and his pretty, pretty face.
Beomgyu was against it at first, teaching their maknae how to kiss. It felt immoral. He’s been with Kai since he was a teenager- the braces, his gangly limbs, his quiet and timid voice. But their youngest is really hard to say no to. Huening Kai just has that face. A face you would commit atrocious crimes for. And so, this arrangement of theirs had been going on for three months.
Even if the older male didn't want to admit it, Huening Kai's kisses were some sort of relief for his oral fixation. Kai’s skills had drastically improved. Far from the clumsy, all teeth and all tongue version of him. The development is quite… frightening. It came to a point where Beomgyu would purposefully extend their lessons because “he doesn’t use his lips right” and there’s “still too much teeth” after a few weeks of them sneaking to their dorm’s bathroom to make out late at night.
It’s selfish, deceptive, but Beomgyu knows that their maknae is not stupid. Kai took the critiques in stride, agreeing to add 30 more minutes to practice his skills. Beomgyu is obviously- elated to see his dongsaeng’s “enthusiasm”.
“Hey.” Kai murmurs, eyes pulling him back to the present. Beomgyu sighs, tucking his hair behind his ear, before giving in and pulling Kai down into a kiss. It starts soft- barely a brush of lips, teasing, testing. But then Kai deepens it, slipping his tongue inside, and Beomgyu trembles at the delicious shiver racing up his spine. “Hyung…” The maknae whispers against his mouth, shifting them so Beomgyu ends up straddling his lap.
Their lips crash again, heated and messy. Beomgyu squirms, trying to get comfortable, only to feel Kai’s growing bulge pressing into him. He grinds subtly, biting back a moan. Kai cups his face, murmuring low. "Sorry, hyungie. I can't risk breaking your fragile teethies with sweets. But this works better, doesn’t it? You like it too. You look like you do.” Beomgyu doesn’t reply, but he melts, relief flooding through him as they kiss again.
Hours of English drills vanish from his mind. His anxiety quiets under Kai’s lips, under his persuasion. It’s addicting- this mix of comfort and filth. Beomgyu didn't want to bother Yeonjun to translate for him. So he wanted to study seriously. “This- is a lot of kissing.” Beomgyu breathes, voice hazy, his head still spinning from the dizzying exchange. His mouth is glossy and swollen from Kai’s relentless teeth and tongue, each nip leaving his lips tingling, raw, and achingly sensitive.
“Yeah?” The faint sting only sharpens the pleasure, turning every throb into something intoxicating. Beomgyu drags his tongue slowly across his lower lip, trying to soothe the ache, but it only makes him shiver. Kai’s lips are no better- pink, slick, and bitten-up, like he’s been ravaged. “Mm.” They devour each other shamelessly, mouths colliding with wet, messy sounds, teeth clashing in their impatience. Their breathing is ragged, hips stuttering against each other in a desperate rhythm.
“I really, really like kissing you.” Beomgyu confesses when they break apart, breath still tangled in the small space between them. “Me too.” Silence falls between the two of them, catching their breaths. They just stare- eyes wide, lips swollen, chests heaving waiting for either of them to come forward and start again. Kai shifts slightly, sweater slipping down his shoulder, exposing a smooth stretch of skin.
Beomgyu’s gaze fixes on it, hunger prickling at the back of his throat. He doesn’t think- just leans in and bites, not hard enough to break skin but enough to make Kai hiss, his teeth dragging into a messy suck before he mouths over it to soothe the sting. “Aish, hyung!” Kai winces, pulling back to glance at the spot on the mirror. “It’ll be a bitch to cover that up.” Beomgyu mumbles an apology, but his eyes are glazed and he’s already half-gone, lightheaded from arousal. It doesn’t sound sincere. Not even close.
Kai sighs, dragging his sweater the rest of the way off. He tosses it aside and tilts his head, tapping a finger along the base of his collarbone, then down to the dip of his chest where clothing or stage makeup could easily cover. His voice is steady, but there’s a tremor under it that makes Beomgyu’s pulse stutter. “Hyung.” He says, eyes holding Beomgyu’s. “We're idols. So leave them here, okay?” Beomgyu’s breath hitches, his throat dry as he stares at the spots Kai so carelessly offered.
His fingers twitch at his sides, itching to grab, to touch, to claim. “...you’re dangerous.” Beomgyu mutters, though his voice sounds more like worship than warning.
And then he caves.
Beomgyu bends low, pressing his mouth right where Kai’s finger left off, teeth scraping, tongue dragging over delicate skin before sucking down hard. Kai jolts, breath catching sharp in his throat, but he doesn’t push him away. If anything, his hand finds Beomgyu’s hair, tightening just enough to keep him there. “Go ahead. Take what I give you. Whatever you want, hyung. I’m right here.” Beomgyu moans against his skin, the sound vibrating through Kai’s chest.
Beomgyu pulls back only to mouth lower, messier, scattering kisses and open bites down the line of bone, the hollow of his collar, until little red blooms begin to rise. Each one is deliberate, marked territory, a place no stylist or fan will ever see but Beomgyu will know is there. “You said here, right?” Beomgyu pants, lips glossy, eyes blown wide as he peers up through his lashes. “Because I’m not stopping.” Kai’s jaw tightens, his chest heaving, but he nods- silent permission that makes Beomgyu’s stomach coil with heat.
“Good.” Beomgyu breathes, before diving back down, greedy and relentless. He doesn’t stop until Kai’s chest and shoulders are littered with blooming marks, scattered proof of his hunger. Only then does he finally sit back, gaze sweeping over the vast expanse of Kai’s skin, flushed and ruined beneath his mouth. Satisfaction hums through him as he leans up and claims Kai’s lips again, kissing him deep and slow.
Kai pulls back just enough to rasp. “God, you’re insatiable. ” Beomgyu only smirks against his lips, murmuring low. “It’s your fault.” Beomgyu feels the flutter of Kai’s lashes brushing against his cheek, light like a feather. It anchors him in the intimacy of it all- their tangled breaths, their sticky mouths, their hearts hammering too hard, too fast, as if they’re both afraid to let go.
“Hyung.” Kai’s voice dips, gravelly, vibrating down Beomgyu’s spine. “Go under the table. I’ll teach you English.” Beomgyu frowns- then realizes what Kai means. His face burns.
Sure, they’ve kissed, grinded, even gotten off fully clothed.
But this? This is different.
Kai reads his silence, softening. “I saw something online- cockwarming. We don’t have to. We can just keep making out, I’ll bring you home, you can use your pacifier and we’ll cuddle. I just thought…” But Beomgyu is already curious, already too far gone. He swallows thickly, hips grinding with purpose. His voice turns sultry as he tugs Kai’s cuff between his teeth. “I want to do it. I want to taste you, Kai-ya. Please.” Kai groans, and their mouths crash together again in a kiss thick with hunger.
Beomgyu pushes his tongue into Kai’s mouth, desperate, tasting him everywhere, exploring every ridge and curve. The taller male’s hands slip lower, cupping his ass in a rough squeeze that makes Beomgyu’s breath catch. “A-ah, fuck-” He gasps, head tipping back. Kai takes the opening instantly, dragging wet kisses down his neck. “Hyung…” Kai’s voice comes out rough, heavy with need, the sound rumbling through Beomgyu and straight to his groin.
When did Kai get so damn hot?
Beomgyu whines, high-pitched and helpless, as Kai tightens his hold, fingers digging into his waist like he’s afraid to let him slip away. “Stop, stop-” Beomgyu pants, nails scraping along Kai’s shoulder. “I wanna… I wanna taste you now.” His words spill out slurred, almost drunken with lust. His body aches with desperation. Beomgyu’s mouth feels empty, his throat dry. He wants Kai heavy on his mouth, wants to be filled, stretched, consumed until there’s nothing left of him but the taste of Kai.
“Okay, okay.” Kai moves quickly, shoving his sweatpants down in a rush, exhilarated that Beomgyu is giving in to his shameless desires. Beomgyu slips off his lap and drops to his knees, swaying for a moment before steadying himself. There’s already a wet patch staining Kai’s boxers, and the sight makes Beomgyu’s mouth flood with spit. He looks up at him through his lashes, lips red and swollen, dragging his tongue across the bottom like he can already taste what’s waiting.
Beomgyu’s thoughts spiral-
How will Kai taste? How heavy will he feel on his tongue? Will his mouth even be able to take him all the way?
A desperate whimper escapes him as he tugs Kai’s boxers down. Kai’s cock springs free, slapping against Beomgyu’s cheek with a wet sound. His breath stutters. Instinct takes over- his hands wrap around the thick length, fingers barely circling it as he feels the heat, the steady pulse, the twitch against his palm. “Fuck, Ning. You’re-” Beomgyu swallows hard, once, twice, three times.
Just looking at Kai’s girth has his lips parting in awe. He’s big- and the thought of having his mouth stretched full around him makes Beomgyu’s throat tighten with want. “Can I put it in my mouth now?” Beomgyu asks, voice wrecked. Kai only nods, jaw slack as Beomgyu licks up the underside, sucking his balls noisily before finally swallowing the tip. Beomgyu gazes up, waiting for Kai to meet his eyes- but he doesn’t.
Instead, Kai’s brows knit in pleasure, lips parted as his cock twitches in Beomgyu’s grip. His breathing grows shallow, ragged, breaking in uneven bursts. Each groan slips out despite his attempts to stay composed, his fingers faltering over the keyboard. “Mmh…” Beomgyu moans against him, letting the sound vibrate along the length in his mouth, eager to put on a show. The reaction is immediate.
“Hyung- fuck. Ah, shit.” Kai’s voice cracks, hand drifting down to brush over Beomgyu’s ear, rubbing at the muscle gently. He knows it calms him, grounds him- even in a moment like this. But Kai doesn’t stop working. His free hand is still on the laptop, typing haltingly, muttering strings of English words before translating them under his breath into Korean. The sight is maddening: Kai juggling restraint and need, trying to focus, while Beomgyu is on his knees, desperate to drag him further under.
“Hyung- shit. Don’t move. You’re supposed to… stay still.” Kai slaps his cock against Beomgyu’s swollen lips, the wet sound obscene in the quiet room. Beomgyu shuts his eyes, tongue slipping out to savor the taps, letting himself be teased and marked with every lazy smack. Without warning, he parts his lips wider and swallows the tip, earning a sharp grunt from the younger.
“Mmh- your mouth is so fucking hot, Beomgyu-hyung,” Kai groans, voice dropping low. “I can’t wait to fuck it… to cum down your throat. But that’s not the plan, right?” Beomgyu’s cock twitches at the words. He moans around Kai’s length, sucking harder before pushing down greedily, trying to take him all the way. His throat protests, a sting blooming as he fails to reach the base. Instead, he curls his fingers around what he can’t swallow, stroking in time with each wet drag of his mouth.
When Beomgyu tries to lift his head for air, Kai’s hand clamps down, holding him in place. Drool spills from the corners of his mouth, dripping over Kai’s cock, messy and slick. Fuck. He’s making such a mess for him, and the sight alone has his own body trembling with need. “Swallow me down to the hilt, and stay there. Mmhh, fuck.” Kai’s voice is low, commanding, his cock heavy on Beomgyu’s tongue.
“I’ll be teaching you basic English sentences. You won’t move until I say so. Got it?” Beomgyu nods obediently and sinks down, throat straining as he takes Kai deeper- deeper still, until his lips press flush against the coarse heat of his pubic bone. He stays there, unmoving, for minutes that feel like hours. Beomgyu’s jaw aches from being pried open, his eyes water from the sheer intrusion. He might not have a gag reflex, but the fullness is still overwhelming- his throat burns, his lungs scream for air.
But the weight filling Beomgyu’s mouth grounds him, a strange kind of relief- peace, even- in the midst of all the ache. He can barely focus on Kai’s steady voice reciting sentences in English, then translating them into Korean, explaining that the former follows an S-V-O structure while the latter follows the S-V-O sequence. What it means? He does not know. All he can think about is how badly he wants to move- how he craves to lick along the thick vein, to swirl his tongue over the slit, to lap up every drop of precum.
Drool spills freely, sliding down his chin, dripping messily onto the floor and over Kai’s thighs. It’s disgusting, humiliating- and yet, Beomgyu doesn’t care. He wants to be ruined like this. He wants to please him. Kai’s hand occasionally pets his head, fingers gentle, nuzzling against his stuffed cheeks as though to soothe him. Every so often, he rewards him:
“Good job, hyung. You’re doing so well. You can move. Just ah- fuck. Just for a bit, okay?”
The praise makes Beomgyu’s stomach knot and his cock twitch. His face burns hotter with every filthy murmur:
“Your mouth is heavenly, hyung.”
“Fuck, you’re so hot like this.”
“Look at you, crying and drooling all over my cock- does it feel nice?”
“You look so pretty with your mouth stuffed full.”
“Just like that. Don’t move. You’re perfect, Beomgyu-hyung.”
The words are like gasoline to his arousal. Beomgyu moans weakly around his cock, and the vibration earns him a strangled groan from the Kai. The maknae’s length pulses against his tongue, twitching with need, and the thought of being filled- of being painted white from the inside- has Beomgyu’s head spinning. “Just a few more minutes. Are you learning, hyung?” Kai teases. Beomgyu nods feverishly, his mind hazy, body pliant. He’s learning something, alright- that it feels blissful to be used like this, to be nothing but warmth and wetness for Kai’s cock.
Finally, Kai strokes his hair and says. “Alright, pull away now. You did so well, hyung. The best cockwarmer- so, so good for me. You still there? Baby?” Beomgyu drags himself off slowly, lips slipping wetly around Kai until he’s free. His eyes find Kai’s immediately, glassy and dazed.
How long has he been down there? Minutes? More? Does it even matter?
He nods weakly, throat working as he swallows back the saliva that’s been pooling around the thick barricade in his mouth. “Words, baby,” Kai urges. When Beomgyu finally speaks, his voice is raw, broken. “Yes… yes, Kai-ya. I’m here. Please.” A string of spit clings stubbornly from his swollen lips to Kai’s cock before falling to the floor with a wet drop. His throat burns, every word strained, but he doesn’t care.
Because he’s not done. Not until Kai fills his mouth. Not until he tastes Kai’s cum on his tongue.
“Can I fuck your mouth now, hm, hyung? Is it okay if I use you? I’m pretty sure you’re enjoying this.” Kai’s words slither through Beomgyu’s ears just as the younger’s foot rubs firmly against his cock. The friction is unbearable, overwhelming- far too much on his already aching length. Beomgyu’s moan rips out of him raw and loud before he slaps a hand over his mouth, as if he can shove the sound back in. His whole body shudders violently, his spine arching as he unravels.
The orgasm crashes through him like a wave. His toes curl hard enough to ache, his eyes roll back, vision going white at the edges. He comes undone in his pants, hot spurts soaking through his briefs, spreading damp across the fabric of his crotch. The wetness clings to his skin, sticky and suffocating, but his cock keeps jerking, pulsing against the ruined mess. “A-ah. Hueningie.” Beomgyu sobs behind his hand, eyes squeezing shut as his hips twitch helplessly, rutting into Kai’s foot like an animal.
He can feel his cum seeping through, staining his pants, humiliating and delicious all at once. Mortification prickles sharp in his chest, but the shame only intensifies the high. He’s shaking, ruined, yet his cock still throbs inside the sticky confines of his clothes, as if begging for more. “Did you just cum from my feet?” Kai asks, his tone cruel and mocking. “Pretty baby is such a fucking pervert.” The words make Beomgyu’s throat close up with tears, his cheeks burning hot.
And yet his cock twitches, oversensitive in the mess he’s made, sending another pang of pleasure through him. “It’s unfair you came first.” Kai continues coldly. “I think you need to be punished, Beomgyu-ssi. Lie down on the sofa. Like that. Yes.” Beomgyu obeys instantly, collapsing onto the couch with his head dangling off the armrest, chest heaving, pants clinging damp to his thighs. Kai’s pleased hum makes his shame twist into something addictive.
“Tap my thigh once if you need to breathe, twice if you want to stop.” Beomgyu nods weakly, mind foggy, cock still twitching against the sticky wet fabric of his ruined pants. “Words?” He swallows. “Yes, yes. Please. Just use me.” Kai steps closer, cock slapping lightly against Beomgyu’s chin, teasing. His hand wraps firm around Beomgyu’s throat- not enough to choke, but enough to remind him who’s in control. Beomgyu opens his mouth without hesitation, tongue stretched out, and Kai finally gives him what he’s been begging for, pushing in slowly until his cock sinks all the way down.
Kai groans at the sight- his hyung’s throat stretching around him, the obscene bulge moving with every shallow breath. Beomgyu’s chest is flushed red, his lashes wet, and the front of his sweatpants is utterly ruined, dark with his release. The mess clings to the fabric, evidence of how easily he came untouched. It’s intoxicating. Kai thinks he could jerk off to this memory a thousand times and still not tire of it.
He’s even tempted to take a picture, to immortalize how beautiful and debauched Beomgyu looks right now- but that requires his consent, and Kai won’t steal this from him.
Maybe next time, he tells himself.
“I’ll move now, hyung,” Kai warns softly. His hips start a cautious rhythm, shallow thrusts pushing between spit-slick lips, careful not to lose himself. It’s his first time doing this- he doesn’t want to hurt Beomgyu. Still, the heat of his throat is maddening. “Shit… you’re so tight. I swear, I could fuck your mouth all day. You like this, don’t you? Being full of me?” Kai’s voice drops into a growl, his fingers pressing more firmly around Beomgyu’s neck, adding pressure but not closing his airway.
Beomgyu whimpers around him, throat convulsing as he swallows, gagging lightly but never pulling away. His sweatpants are sticky, cock twitching beneath the damp fabric with every thrust, the wet patch spreading further as his body betrays him. Kai loses control, hips snapping harder. “Do you want me to ruin you, hyung? Hm? Want me to keep your mouth stuffed with my cock, fuck you until you can’t speak?” He watches his hyung gag and shiver, and it makes him hungrier.
“Ah, you love this… my perfect little cockslut.” Beomgyu’s fingers clutch at his thighs, muffled noises vibrating against Kai’s length. He lasts five minutes before his trembling hand taps twice against Kai’s skin. He reacts instantly, pulling out and cradling his hyung’s head, panic flickering across his face. “Hyung, are you okay? Did I push too hard? Shit, I’m sorry.” His thumbs brush over Beomgyu’s throat as if to soothe the ache, his eyes searching his hyung’s tear-streaked face with genuine worry.
Beomgyu’s heart stutters at the tenderness- it’s almost unbearable how sweet Kai can be after breaking him apart. He clears his throat, voice hoarse but steady. “I’m fine. My neck just aches a little. I’ll move this time. If that’s okay?” Relief softens Kai’s expression. He presses a kiss to Beomgyu’s damp forehead and strokes his hair. “Of course, hyung. Do whatever you want.” Beomgyu sits up, holding Kai’s heavy length in his hand before diving back in.
And when he swallows him down again, this time setting his own pace, Kai nearly blacks out from how good it feels. “Fuck, hyung. You’re amazing.” Beomgyu bobs his head, tongue dragging along the underside of Kai’s cock while his hand massages the blond’s balls. It’s sloppy, wet, obscene- the kind of blowjob that fills the room with squelching noises and choked moans. Both of them are sweating buckets, and even with the AC humming, the heat radiating off their bodies drowns out the cold.
“I’m- fuck. I’m about to cum, hyung.” Kai’s voice cracks, desperate. Beomgyu only hums in acknowledgment, reveling in every broken grunt spilling from the maknae. His jaw aches, lips swollen and slick, throat raw- but he doesn’t care. He wants it. He wants to taste Kai, to wring him dry with nothing but his mouth. He sucks hard at the tip, fist pumping with a tight grip, his other hand kneading Kai’s balls.
It’s overwhelming- messy, hot, intoxicating.
“Fuck, I’m cumming. Shit, Beomgyu-hyung!” Kai groans, hips jerking as he forces Beomgyu down onto his cock. Beomgyu takes it all, throat tightening around the rush of thick heat spilling into his mouth. Slowly, he pulls off the semi-hard length, opening his mouth to show his tongue coated in Kai’s cum. Kai’s hand slips under Beomgyu’s chin, thumb swiping some of the mess across his lips before pushing it back on his tongue. He watches, eyes dark, as the sticky strings cling between his fingers.
“Fuck… look at you,” Kai murmurs, voice rough but affectionate. “Made me feel so good, hyung. You did so well for me.” Beomgyu whines at the praise, his lips closing around Kai’s finger to suck it clean. “Swallow.” Beomgyu obeys, gulping down every drop with a shiver. When he sticks his tongue back out to show it’s clean, Kai’s breath stutters, pressing a kiss on his spit slicked mouth.
“You good, baby?” Kai asked softly, crouched in front of the sofa where Beomgyu was slumped back, boneless. He nods weakly, grinning at the endearment. “I’ll get you some tea to help with your throat. Don’t worry, I won’t be gone too long.” Kai kisses his swollen lips before heading off, wearing his sweater and tugging on a clean pair of joggers he must’ve set aside earlier. The way he’d prepared made Beomgyu giggle like an idiot the second he left the room.
What a pervert.
“Wow… that was just. Wow,” Beomgyu murmurs to himself hoarsely, letting his head flop against the back of the couch. His lips were tingling, his chest still fluttering. “The angel of the group, huh? Can’t wait to experience that again.” He touches his throat, eyes glossy. “Don’t worry, I got you.” Kai’s voice returned, warm and steady, as he stepped back in with a steaming cup of lemon tea. He carefully hands it over, watching Beomgyu wrap both hands around it.
“Sip slowly.” He murmurs. Beomgyu barely has time to take a cautious gulp before Kai is back at his knees, sliding his pants and boxers off with gentle hands. “Kai-ya, be careful! I’m drinking tea.” Beomgyu complains, trying not to spill. Kai just chuckles, grabbing a few wet tissues and tenderly wiping away the mess from Beomgyu’s thighs and stomach. “Relax, hyung. Let me take care of you.” His voice is soft, sure- like this is second nature to him.
When he finishes, he leans closer to wipe Beomgyu’s flushed face, brushing at his damp bangs with careful fingers. Then, without warning, Kai’s hands move to his neck, kneading gently at the strained muscles. Beomgyu melts instantly, a groan slipping out before he can stop it. “There we go.” Kai murmurs, thumbs pressing just right. “Worked you a little too hard, huh?” Beomgyu whines, hiding his face behind the mug.
Kai smiles, reaching for the clean boxers he brought earlier. “Lift up a little for me?” He coaxes. When Beomgyu obeys, Kai slides them up his legs, adjusting the waistband before patting his thigh softly. “Perfect. Fresh and comfy.” Beomgyu blinks at him, touched beyond words, and takes another sip of tea to cover the warmth blooming in his chest.
“You did so well, hyung. Made me feel so good,” Kai says earnestly as he sits beside him, an arm slipping behind his shoulders. “Think you actually learned something?” Beomgyu’s face goes red instantly, and he buries it into Kai’s shoulder. “…A little. Maybe we should do this more often.” Kai chuckles, kissing the top of his head. “That’s good, hyung. Always eager to learn.” Beomgyu rolls his eyes. “Want us to try something different?” He teases, wiggling his eyebrows just to make Beomgyu laugh.
Beomgyu groans, putting the cup down and punching his arm weakly. “Maybe next time.” He replies, shy and soft, fingers curling in Kai’s joggers. Kai tugs him closer, letting him rest against his chest, one hand still lazily rubbing the back of his neck. “Next time, then. And every time after, if you want.”
