Jaeyun gets mouth sores.
Quite frequently.
Jungwon had his fair share of mouth sores, but they’re way more rare than Jaeyun’s. And less painful. Jaeyun’s mouth sores are rather big and sometimes it gets so bad that he can’t even eat properly.
He also utterly hates the medicine he has to receive for them.
All these are known facts that everyone is aware of—the members, the staff, the fans.
Not just because Jaeyun complains a lot about it, but he’s melodramatic so there’s been quite a few incidents caused by this. Once, while one of the staff was trying to apply the medicine, Jaeyun abruptly turned and bumped into a tray, unfolding a chain reaction that ended with Jongseong and Sunghoon’s shirts being stained with foundation right before a performance. Another time, Jaeyun almost broke his arm because he recoiled from the medicine again and fell off a chair. And the one Jungwon finds the funniest is when Jaeyun started running because of the pain caused by the medicine and bumped into Sunoo, effectively knocking their heads together pretty hard. Jungwon was there to witness it. He had a laughing fit about it.
So now they’re being a bit more careful about applying Jaeyun’s medicine.
The last time, they had to tie him to a chair. That was quite fun to watch. Jungwon thinks Jongseong enjoyed it the most though.
That time, Jaeyun asked Jungwon to do it. He tried, but Jaeyun wouldn’t stand still and he passed the task to their staff.
A couple weeks later, they're in their dorm, Jungwon scrolling through his phone on the couch in the living room with Jongseong sprawled on the other side of the couch. Jaeyun pads softly into the room and comes to a stop in front of Jungwon, a couple cotton swabs and the bottle of medicine in his hand. He has a crooked smile on his face and puppy eyes so Jungwon can’t refuse. Even when Jongseong offers his help, Jaeyun just says “I want Jungwonie to do it” so Jungwon really can’t refuse. Jongseong just shrugs and goes to take a shower.
Jungwon rises from the couch to stand in front of Jaeyun. He takes a cotton swab and soaks it up with medicine, watching Jaeyun as he tries to brave himself for the pain. He takes hold of Jaeyun’s chin, which prompts Jaeyun to open his mouth. Right as Jungwon closes in with the swab, Jaeyun suddenly closes his mouth.
Jungwon gives him an unimpressed look.
“I just wanted to say there’s two this time. One on my tongue and one on the skin inside of my mouth,” Jaeyun explains, dragging his lip down to show Jungwon.
Jungwon nods. “Got it.”
Jaeyun nods back and opens his mouth again.
Jungwon barely gets to touch the blister with the swab before Jaeyun retracts, closing his mouth again.
“Hyung,” Jungwon warns, grip tightening on Jaeyun’s chin, keeping him in place.
“I can’t help it. It hurts,” Jaeyun whines, lips jutting in a pout.
Jungwon takes a deep breath.
“We’ll try it this way then.”
Jaeyun furrows his brows and opens his mouth to speak. Jungwon doesn’t give him enough time, his fingers retracting from his chin and gripping his shoulder instead, pushing him into the soft cushions of the couch. He ignores the squeak Jaeyun makes and straddles his thighs, strategically placing his weight on Jaeyun’s legs so that he can’t get up. With his palm still on Jaeyun’s shoulder, he presses the boy into the back of the couch. For a moment he wonders if he’s being too rough, but the look on Jaeyun’s face—wide eyed and slightly open lips—keeps him in place.
“Either stay still or I’ll have to tie you to a chair again,” Jungwon commands in a calm voice. Jaeyun’s eyes widen even more and for a second he looks conflicted between which option he prefers more. Jungwon tries to suppress a smile—he had a feeling Jaeyun enjoyed being tied up a little more than he lets on.
Jaeyun blinks a few times, then promptly nods. “I’ll stay still.”
Jungwon’s fingers find their place back on Jaeyun’s chin. He uses his thumb to pull Jaeyun’s bottom lip down, exposing the inside skin. The moment the medicine imbued cotton touches the wound, Jaeyun unconsciously tries to close his mouth. Jungwon presses harder on his lip, grip tightening on his skin. He pushes Jaeyun’s head back into the cushions, holding him in place. Jaeyun gasps and makes a small surprised sound in the back of his throat.
Jungwon carefully rubs the medicine over the blister and Jaeyun screws his eyes shut in pain, groaning softly, hands tightly clenched on the couch. Jungwon lets him breathe for a moment, then goes in again.
“Well that’s an interesting method to keep him still.”
Jungwon starts at the sudden voice, somehow pressing Jaeyun even more into the couch, making him whimper quietly.
Jongseong is watching them from the bathroom door, an amused quirk to his lips.
“Does the job,” Jungwon offers, shrugging.
“I bet it does,” Jongseong says, his smile widening. Jungwon rolls his eyes. Jongseong spares another mirthful glance to Jaeyun, then snorts and leaves to his room. He’ll probably tease Jaeyun further when he goes back to their shared bedroom, but that’s none of Jungwon’s business.
Jungwon turns his eyes back on Jaeyun, who’s been uncharacteristically quiet during the entire exchange, when he’s usually the first one to bite back at Jongseong.
Jungwon’s breath catches for a moment when he realizes his thumb is still pressing on Jaeyun’s lip, almost entering the other’s mouth. Jaeyun’s eyes are a bit dazed and he’s looking up at Jungwon with slight confusion and a bit of something else. It unnerves Jungwon, how much he wants to fully slide his finger in and watch Jaeyun’s plump lips wrap around it.
The moment is broken when Jaeyun abruptly shuts his eyes, a harsh exhale blowing out through his lips. The sudden warmth on Jungwon’s wet thumb shakes him out of that train of thought. He lets go of Jaeyun’s lip, trailing his finger down the older’s chin until his hand leaves his face entirely.
Jaeyun coughs. He seems flustered when he says, “I think that’s enough for today.”
Jungwon just nods, throws the used swab on the coffee table.
“Thank you,” Jaeyun mutteres.
Jungwon takes in his demeanor, not entirely familiar with such a shy Jaeyun. He’s used to seeing a more playful and zealous side of Jaeyun, even cheeky sometimes. This foreign flustered side makes something in Jungwon’s chest swirl in interest.
He feels Jaeyun grow restless under him and he belatedly remembers that he’s sitting on Jaeyun’s thighs. He throws himself off to the side, gently crashing onto the other side of the couch. He smiles when he sees Jaeyun’s eyes turn to him.
“You’re very welcome, hyung.”
·𖥸·
The next day finds them in the same place.
Jungwon is lounging on the couch, this time just by himself. He’s watching old fancams of Jeon Jungkook, just something he does sometimes to pass the time. It’s fun and also a learning experience all in one.
The apartment is almost empty. Most of the members are out shopping, Heeseung is at the studio working on something with one of their PDs. Jaeyun is in his bedroom, sleeping.
Jungwon has been enjoying the alone time, happily munching on a pear.
Distracted by the videos, Jungwon doesn’t hear the soft pad of footsteps until he sees Jaeyun standing by the side of the couch. He looks sleepy, lips downturned in a pout.
“Thought you were sleeping, hyung.”
Jaeyun shakes his head, his fluffy, messy hair moving around with the motion.
Jungwon moves his legs to the side, making space for him.
“Couldn’t fall asleep,” Jaeyun says as he sits.
Jungwon nods in understanding. “Want a pear?” he offers, reaching for the fruit bowl he put on the table.
“Nah, it hurts too much having to chew hard food.” He says it with a huff of laughter, but it makes Jungwon frown.
“Not better yet?”
At the shake of head he receives, Jungwon sits up, inching closer to Jaeyun’s side.
“Lemme see.”
Jaeyun dutifully opens his mouth, allowing Jungwon to check. Jungwon’s mouth twists at the look of Jaeyun’s blisters. It does look like it hurts quite a lot.
“Bring me the medicine.”
Jaeyun’s features twist, reluctant, but eventually he moves to get it with a sigh.
Jungwon bites his lip to stop himself from smiling. He feels bad for his hyung, but can’t deny that he’s quite cute, all pouty and huffy.
When Jaeyun returns, he sits back on the couch and offers Jungwon the swabs and medicine.
“Do you want to go about it like the other day?” Jungwon asks softly as he dips the cotton in medicine.
His eyes raise to see Jaeyun looking somewhere on the ceiling. The other shrugs. “It did keep me from moving too much.”
Jungwon huffs a laugh and throws a leg over Jaeyun’s thighs, settling down in his lap. He cups Jaeyun’s chin, already familiar with the action.
“Open your mouth for me, hyung.”
It’s not his intention, but he does notice how the words have startled Jaeyun. His eyes are wide, and so very pretty as they look intently to Jungwon. His lips slowly part, allowing Jungwon access. He presses his thumb to Jaeyun’s bottom lip again, shiny with spit after having licked his lips prior. He’s noticed this habit of Jaeyun’s, licking and biting his lips, playing with his tongue. It’s quite distracting if Jungwon thinks more about it.
He starts softly pressing the tip of the swab to the lesion and Jaeyun winces in response. Jungwon pins him back onto the couch. Jaeyun’s breathing turns labored and Jungwon stops his movements.
“Okay?” he asks gently, his grip on Jaeyun loosening.
“Yeah,” Jaeyun breaths out.
Jungwon returns his attention to the job. This time he rubs a bit harder on the blister, to make sure it’s coated in medicine.
Jaeyun whines, face scrunching in pain. He bucks off the couch, probably to try to move away. However, Jungwon’s hips restrict his movement, so what happens is this—their crotches brush, the movement jostles Jungwon forward, their faces close to each other, both gasping in surprise at the sensation.
There's a moment of complete silence. Jungwon collects himself first upon noticing that glazed look taking over Jaeyun's eyes, realizes that perhaps his heavy breathing is not just because of the pain.
Jungwon lets go of his face and trails his palm down to Jaeyun's chest.
"Hyung—"
"I'm sorry," Jaeyun rushes to say, frantic eyes moving all over Jungwon's features.
"It's okay," Jungwon assures, pressing back down on Jaeyun's lap. There's a new purpose in the movement now, and Jaeyun catches on to the subtlety.
Their faces are still close to each other, hovering, warm breath fanning over each other's skin.
Jungwon’s brain is suddenly registering every effect he has on Jaeyun. He moves a little on his lap, slowly, carefully. Jaeyun's breath hitches, eyes closing tight.
Jungwon smiles. Presses on Jaeyun's chest, feeling the toned muscles underneath his palm. "Hyung," he drawls, voice low and sweet. "Open your mouth."
"I think it's enough," Jaeyun croaks, voice breathy and unsteady.
"But I still haven't finished."
"That’s fine." Jaeyun sounds like he's been running and it makes Jungwon’s lips quirk further.
"Hyung, look at me." The demand in his voice is clear and he's pleasantly surprised when Jaeyun listens, meets his eyes with uncertainty. Jungwon knows what he wants, what they both want, what he has to do to make that irresolution leave Jaeyun. His palm moves up a bit, settling at the base of Jaeyun's neck, softly pressing there until Jaeyun's chest heaves with a shaky exhale. He braces himself there and grinds down slowly, intently.
Jaeyun’s eyes widen, and Jungwon wonders if they can grow any larger, if he can make them grow any larger.
He feels Jaeyun’s body turn taught for a second, then he's pliant underneath Jungwon.
If pleasure can make Jaeyun respond so well, Jungwon is not gonna pass on the opportunity.
"Can you stay still for me, hyung?"
The response is a quick jerk of Jaeyun's head.
"Are you gonna be good for me, hyung?"
Another enthusiastic nod, and a loud gulp.
"You know good boys get rewarded." Jungwon's voice is suggestive, trying to be as clear as possible of his intentions.
Jaeyun’s eyes shine with lust. Jungwon feels the vibration of his low moan under his fingertips, and swallows in anticipation.
"Open," he demands.
Jaeyun obeys instantly, tongue out for Jungwon to see.
Jungwon gets back to work, making sure to apply sufficient medicine to the blister. Jaeyun is still through it all, features scrunched in pain, trying to suppress his whimpers. His hands are holding on to Jungwon's thighs, fingers tightening and untightening around them. Jungwon can feel Jaeyun's intent eyes staring at his face, carefully taking in every single feature.
The moment he's finished, he throws his utensils to the side.
"Good boy," he whispers on Jaeyun’s cheek and grinds down on him, purposefully. They both moan in unison and Jungwon leans down to take Jaeyun's lips with his own.
It's a slow kiss, tentative, gentle. He can taste the medicine on Jaeyun's lips. Jaeyun, despite his pliant state, is still just as eager as always, licking at Jungwon’s lips until Jungwon opens up for him.
"Fuck," Jaeyun suddenly curses, leaning his head back on the couch. "It hurts."
Jungwon snorts, ungraceful. "Let's keep to close mouthed kisses for now." He noses down the line of Jaeyun's jaw, leaving small kisses over his heated skin. It's quite an innocent gesture compared to the slow, teasing grinds of his hips. Jaeyun's hold on him has tightened, the older trying to make Jungwon move faster.
Jungwon slows down his movements even more and Jaeyun whines in protest. He shows mercy on him though, slipping a hand underneath his sweatpants and boxers, taking him into his hand. Jaeyun mewls in response, the sound unfolding something in Jungwon’s chest.
He surges up to press his lips back to Jaeyun's. He wants to devour him, open him up completely, watch him writhing beneath him. Yet he's still cautious of Jaeyun's pain. And honestly that medicine doesn't taste that well. He feels for Jaeyun, having to go through all that.
Instead, his lips slide down Jaeyun’s face, to his jaw again, down the column of his neck. He feels the startling need to bite down and suck on his skin, yet he's aware he can't mark his hyung. Not somewhere so visible, at least. He licks at the skin and presses open mouthed kisses, ecstatic at the feeling of Jaeyun's rapid pulse under his lips. He tries to keep his hand movements coordinated, but Jaeyun keeps buckling into his fist, searching for his release. Their rhythm is messy but it does the job, Jaeyun coming over his hand in a few more strokes.
"Oh my god," Jaeyun breathes, falling back onto the couch, spent.
Jungwon pulls out his hand from Jaeyun’s boxers and cleans it off in kitten licks. He's looking directly into Jaeyun’s eyes through it all.
Jaeyun seems mesmerized for a few moments, still and unblinking. Then, "Oh my god." He closes his eyes and moans.
Jungwon grins, menacingly.
"Yang Jungwon, are you trying to kill me or something?"
Jungwon blinks, the picture of innocence. "No, hyung. I was just trying to help."
Now it's Jaeyun’s turn to snort. "Yeah, yeah. You did help."
Jungwon leans down to press a quick kiss to the corner of his mouth.
"You're the only one allowed to apply my medicine from now on," Jaeyun announces and Jungwon can't help but smile, pleased.
He spares a quick glance around, abruptly remembering that they're in the living room.
"Yeah, well, maybe next time we should do this in a bedroom and not where everyone can see," he suggests, amused despite himself.
"Yeah, sure, where Jongseong can walk in on us and tease the hell out of me for eternity."
A soft laugh, his fingertips skimming over Jaeyun’s collarbone.
"I think he wouldn't mind walking in on that."
