Thin Walls (Jaehyun x Reader)
Hey! Long time no see! It’s been a minute since I last posted something or filled a request, and the guilt of not doing so was slowly eating away at me lol I managed to throw this one together after forever and it took so long because I was struggling hard core on the actual smut. It’s just so difficult trying not to repeat a scene I’ve done previously in the exact same way, etc. But finals are coming up, and I’ll be trying my darndest to chip away at these requests as best as I can! Hope you all enjoy this one!!!
P.S. I miss his curly permed hair, it brought me so much joy :’) He just looks so soft and cuddly, bless his soul I love him so so much !!
Moving to one of the biggest cities, you had your hopes high, but not too high. You knew it wasn’t a perfect place, with perfect people who had perfect lives and perfect apartments. There were the dumpster divers, the druggies in the alleyways, and the snobs that flaunted their glittery 24 caret plumage on their wrists and necks, suffocating themselves with mink coats and expensive cigarettes. But you were determined to ignore all of it, the people who mattered were like you; starving, but alive, living their big dreams regardless of the struggle. You clung to those people, the places they frequented, and learned to love and appreciate the side of this city that was your new home. You were stable and free now, able to pursue the things you enjoyed and make a living to support yourself.
If there was one thing you loved above all else, it was your flat. It had been a treasure find during a hot summer night not very different from the one now, your mind a little hazed by the one too many drinks you’d tipped back at a friend’s house party. Your body buzzing as you wandered back to your temporary home at a hotel, feeling drawn to take a new street instead of the subway.
The sign was a rickety chalkboard with words scribbled across it in blue chalk, advertising an empty apartment for rent. You almost paid no heed to it, wanting nothing more than to collapse in your bed and pass out, maybe even throw up in the nearest trash can. Something prompted you to grab one of the pamphlets pinned to the board and shove it in your purse for later, didn’t hurt to try, right? You didn’t think twice about it until the next morning when the sun cracked above the horizon, bolting upright and scrabbling for your cellphone to dial the number, despite your massive head ache from your hangover. Pickings were slim in the trendy city of Seoul, millions of people vying for a place to call their own, you had to give it a try because it might be your only chance for a while. Plus, you were tired of hopping from one cheap hotel to the next and crashing at your friends’ flats. You needed a place to call your own.
A soft spoken old woman had picked up, her motherly voice cooing like a mourning dove as she gave you a time to stop by to tour the flat. You had arrived way too early due to eagerness, the building being located on one of the most popular and famous streets only added to its charm. Lovely and eclectic themed coffee shops, boutiques, and makeup and bookstores lined the street, making it one of the busiest. If you weren’t already ready to sign the dotted line, the moment you walked in was the last word.
When she had brought you up that creaky elevator that seemed to soar up and up into the sky, your breath had been taken away as soon as you walked into the apartment. It wasn’t the newest, but it had an old charm to it. Exposed brick on the outer walls, windows stretching wide to depict the city skyline, and it could be all yours. She had warned you about some problems like creaky pipes, leaks, and especially the thin walls since you shared one with one other apartment. You could care less at that point, already ready to sign the contract and call the humble little place yours.
So here you were now, the humid night setting in as you sat lounging on your couch, dripping in sweat and absolutely sweltering. All your windows were cracked, the old AC cranked as high as it could go, and one greasy fan that struggled to spin, which hardly made much of a difference at all. You were dressed in only your underwear and a sports bra, trying to cool yourself off as you pressed an ice pack to the back of your neck with another annoyed groan.
Today had been your day off, wanting nothing more than to go outside and enjoy it, but the heat was so stifling you’re sure you would have roasted under the sun in five minutes. So you stayed inside, trying to mind your own business as usual and take a day to yourself. All afternoon you heard the same old usual sounds from your next door neighbor, not even bothered by the incredible thinness of the wall that divided your two apartments anymore. He was young and gorgeous, a college student living off campus, pursuing a degree in music. You’d met him only on a few occasions, and he was sweet and personable enough, but it felt like the two of you were connected somehow. You knew him better than those simple hellos in the hallway and so did he. The wall was so thin and hollow that the two of you could almost perfectly hear what the other was doing all the time, which irked and frightened you at first. Sometimes it even felt like your flats weren’t separated at all, you wouldn’t have been surprised if you saw him walking around your living room one day.
You didn’t want to lie to yourself, he really was completely beautiful. Your heart nearly leapt into your throat every time you saw him smile, his dimples poking out cutely at even the smallest quirk of his soft looking lips. He towered over you, making your pulse race whenever he stopped you in the hallway to let you know about a problem the building was having, his warm hand burning a permanent brand on your shoulder. You couldn’t say you were in love with him, not yet. But you could say you liked him very, very much and at the moment was completely entranced by him.
Jung Jaehyun loved to sing, his velvety voice usually would ring throughout your floor during the day. He sang everything, even his own compositions, which he knew you could hear, almost like he wanted to know your opinion. You loved to listen to him while you cooked, or when you showered, sometimes humming or singing softly back to him, just so you could let him know it was okay for him to continue. In all honestly, you enjoyed it more than you realized, and he knew it too.
Little did you know, he knew a lot of things. Those walls kept no secrets, especially the ones you wouldn’t even dare utter aloud.
Passing him in the thin, musty hallway always seemed to make your heart beat fast enough to burst from your chest. You were sure that he could probably see your whole body shaking from just the greeting he shot you, dimples poking out coyly as he pressed himself against the wall to let you pass. He smelled like a man, rough and homey, something familiar and something that made you crave to be near him again and again. You hated how easily he could twist you around his finger and the two of you were barely friends, just neighbors politely living next to one another.
You let your head fall back against the couch, the magazine you were using to fan yourself picking up speed as you thought of your neighbor and his mischievous ways. He was probably in the same position as you, slouched onto his couch, most likely gloriously shirtless as he attempted to break the relentless heat wave that was trapped in the city. Your face turned a darker shade of red, childishly tossing your magazine across the room as your mind swam with desirable images of Jaehyun lounging on his couch with less and less clothing as time went by. You groaned loudly, standing up to go suffer in bed when you heard a familiar noise on the other side of the wall, a velvety humming.
You crept silently over to the wall, wincing every time a rickety floorboard creaked. Settling softly against the wall, you pressed your ear to it, straining to hear just what was happening on the other side. It was a gentle hum, reminiscent of a cat purring, so close to the wall the sound tingled your ear. His voice so silky that even the most expensive lengerie couldn’t compete with the sheer amount of sexiness and comfort you received from hearing it.
“The good part comes between wanting and needing,” Jaehyun crooned from behind the wall, and you turned to press your forehead to the faded blue paint, tucking a strand of hair behind your ear as you swayed back and forth where you sat. He knew oh so well how much you loved it when he sang sensual pieces; knew how much the sound of him humming those words turned you on. It was an unspoken arrangement that neither of you were prepared to mention when you passed each other in the hall.
Because who knew what would happen if you did? Where it would lead?
You swore you heard the boy on the other side give a sharp inhale of breath, but paid no attention when he sang the next bit, “When it’s less about eating and more about feeding.”
Biting your lip, you slid a hand up and down your exposed thigh, sighing wantonly when you heard him shift on the other side. You wished desperately for him to be in front of you, arms open for you, lips waiting to be kissed, and eyes filled to the brim with lust. You gave a soft gasp as you slid a hand over your panties, feeling a heat beginning to grow in your stomach, and a wetness form in between your legs.
In between…right where you wanted Jaehyun.
You heard him shudder on the other side of the wall, the erotic and strangely familiar metallic sound of a belt unbuckling caused your hips to buck into your fingers that were gliding over the covered folds of your heat. You pressed a finger to your clit and bit back a moan when you heard the clunk of a buckle hitting the wood floors, a relieved groan reached you through the wall and you cried out in response.
How he managed to continue to sing was a mystery to you, but you could hardly believe you ears as he sang, “You know the best could always be better.” You pulled your panties down your smooth thighs and immediately slid a finger into your soaking heat, illiciting a gasp that mirrored Jaehyun’s. The way you practically dripped onto the wood floors made you blush as your walls tightened around you finger. You could practically hear the smirk in his voice, barely being able to imagine him without passing out from want; pants unbottoned, belt messily undone, briefs hastily pulled down in order to let his hard member breathe. His hand almost shaking as he attempted to control the quavering in his voice, “When the hardest could be harder…”
You heard him groan and you moaned in response, nails clawing against the wall as you pumped your fingers inside yourself, imagining it was him. You slumped against the wall and used your other hand to rub your clit hurriedly, feeling so close you could hardly stand it. You clung on to each word, knowing his hand was moving in tandem with yours, breathing synchronized as he practically moaned the next words, “And the wettest is wetter.”
You cried out his name, just about to finally come when his voice cut you short, “Stop, _____.”
You immediately retracted you hand while panting, waiting for him to continue, wanting to whine from your need to release. His voice was low, calm and full of command, but you heard how he strained to keep it level. “Listen closely, baby girl. Go unlock your door. Then I want you in your bed. Naked. Do you understand?”
Your lips quivered in want, “Yes.”
You didn’t wait for him to tell you to go, your body moved quickly, instinctively and driven by want as you scrambled to the door. Your hands trembled as you slid the lock over, hardly believing what you were about to do. You clambered towards your bedroom, clicking all the lights off and flicking on your bedside lamp and fairy lights you had strewn over your headboard. Then you yanked your curtains open on your large window that took up an entire wall, allowing the rainbow ambient light ofSeoul to seep in through the glass. You stilled for a moment, hearing footsteps in the hallway, the clunk of your door handle being grasped as it was turned. You panicked and struggled to rip off your panties and sports bra, realizing as soon as you hopped on your bed that your entire room was a disaster. You were about to scream into the nearest pillow when you heard short knocks on your door frame. Too late now.
He was too much, period. The boy was sculpted from something close to the gods, with a body gorgeously lean, his frame broad, and legs long enough for you to climb. He wore nothing but a pair of dark briefs, the outline of his hard member pressing insistently against the fabric as if taunting you. Everything about him was either dark or light, a contrast that made your knees weak. His dark hair was a beautiful mess, like he frequently ran his fingers through it. His ebony eyes drew you in and kept you there, not allowing your own gaze to wander anywhere else. Jaehyun stepped towards the bed, fingers running over the cool silk of your sheets you had spent so much money on. You saw a small smile flicker over his lips that made your body quiver, knowing exactly what he was thinking.
It’s going to be fun ruining that silk.
When he got onto the bed, you gasped at the predator look in his eyes as he crawled towards you on all fours. The bed creaked lightly as you shifted back on instinct, even though you felt so drawn toward him, wanting nothing more than to finally touch him. You realized you have never laid a single finger on him and he you, but both of you were so completely enraptured with one another even when there was a wall separating you. It was honestly poetic, and strangely beautiful.
Unmuffled, his voice was even more velvety, “You don’t know how often I thought about this very scenario.” He laid you down and crawled up your body, careful to not touch you, not yet. “All those nights when I could hear you touching yourself, moaning my name as you finally came.”
Your body shook, wanting to squeeze your eyes shut from embarrassment, but Jaehyun held your gaze. You pressed your thighs together as he leaned closer to you, his hair tickling your forehead, “Were you imagining my fingers, baby girl? Or maybe my tongue?”
You could hardly answer, eyes wide as his lips barely grazed yours as he whispered, “If you really want it that bad, princess, why don’t I give it to you?”
With that he closed the gap between your bodies, allowing his entire frame to press against you along with his soft lips. They glided so easily against yours, like they were meant for one another. One of his hands came up to tangle in your hair, allowing him complete control of you as he slipped his sinful tongue into your mouth. You moaned in appreciation at the slick feeling of his tongue sliding against yours, tasting the tea he had been drinking earlier. He pulled away for air, panting as he slid down your body dragging his tongue over your skin. He pressed wet kisses to your breasts and ribs, hands gripping your hips as he groaned against your skin, “I’m going to cover every inch of your skin with my tongue, until your fucking begging for it, baby girl.”
You gazed down at him as he worked lower and lower, your body glistening from where his mouth left. Hovering over your dripping heat, he blew cool air on it, smirking at the way you arched off the bed. The moment his tongue made contact with your lower lips, your hand found his dark locks, tangling your fingers through them. He released a groan from the taste, attacking your clit with his lips as he sucked at it mercilessly. His ebony eyes stared up at you and you could feel the smirk against your inner thigh as he went to bite at the soft skin there, leaving a dark purple hickey. He didn’t leave just one though, that wasn’t Jaehyun’s style. He wanted to wake up to you tomorrow morning, thighs littered with bruises and violently purple hickeys. As he nosed along your inner thighs, your body began to tremble and ache as he revisited old markings, biting and pressing kisses to them, “J-Jaehyun!…Please!”
He pulled away and regarded you with amusement, “Please what, baby girl?” He was enjoying himself, dragging his tongue over those cheeky bruises proudly.
You shifted your hips to make your point clear, too embarrassed to ask aloud for what you really wanted him to do. He tilted his head innocently, licking his bottom lip from one corner to the other as he traced his tongue over your taste. Deep down you realized that Jaehyun wouldn’t give you what you wanted if you didn’t give him what he wanted. It was a game of give and take, and you needed to swallow your pride.
You gulped, voice straining with want, “P-please fuck me with your fingers and tongue, Jaehyun.”
“Hmmm,” he simpered, letting a finger lightly trace over your clit. “Since you were such a good listener earlier, I’ll give you what you want.” He leaned closer to your lower lips, but stopped himself, looking up at you through his lashes as he whispered, “Make sure to pay me back later though.”
You let out a sigh of relief as he began to eat you out, his tongue doing things you’d only imagined before all of this. You almost had to pinch yourself because everything felt so surreal. Your neighbor, who you’ve only politely spoken to in the hallway, was now eating you out better than any other person you’ve been with. You weren’t sure you were going to survive until morning.
Jaehyun worked a finger past your folds, the slickness of your heat allowing it to slide in easily. At the sound of your moans of approval, he worked another finger in with a small smirk, hardly believing all this was happening as well. He held the same sentiments as you, having to mentally slap himself from stopping just to stare in awe at you. You had to be the most beautiful and interesting girl he’d ever laid eyes upon, the first moment he saw you he was already decided. You were his muse. The mysterious subject to his songs he wrote, the girl in all of them…they were you.
“______,” he hummed your name, allowing his tongue to soak in your taste, committing your moans and sounds of pleasure to memory. To him, they were more beautiful than any song he could compose, completely gorgeous. His fingers quickened their pace, feeling your walls convulse around them as you neared release. He pulled his mouth away, allowing his fingers to do all the work as he regarded you with that dangerous look in his eyes again. He looked like a predator debating whether he was going to eat you now or later as he murmured, “Should I let you come, ________? Have you earned it?”
You whimpered, hands scrabbling for his hair and tugging at it insistantly, “Y-yes.”
He slowed his pace, brows furrowing, “Yes, who?”
“Yes, Jaehyun!…,” you recovered frantically, hips urging him along as he continued at his original pace.
“That’s what I thought,” he simpered, fingers thrusting into you so powerfully that your body rocked the bed. “How bad do you want it? Tell me just how bad you want me to make you come.”
His fingers, quickening slightly, distracted you as you attempted to form a coherent sentence, “I-I want it, Jaehyun!” Thinking swiftly, you added, “Please, baby!” Looking pitiful was always a good way to get what you wanted, or it could just make things much worse.
Luckily, Jaehyun’s dark eyes softened as he saw the tears beginning to pool in yours, “Whatever you want, baby girl.” He bent his head down again, his hot breath on your inner thighs sending your mind into overdrive as he latched onto your clit and his fingers sped up. Your toes curled, thighs trembling as your high approached, hips rolling into Jaehyun mouth as you fucked back against his fingers. You cried out, body shaking as he finger fucked you through your high, drawing out that feeling of ecstasy for as long as he could.
He didn’t stop there though, he kept going long after your release ended. Weakened by your orgasm you squirmed beneath him and his mouth as he continued to work you, fingers not quitting their breakneck pace. You cried out, hands weakly trying to push him away as the overstimulation made your thighs shake, “J-Jaehyun please!…”
Tears of passion leaked down your face from the sheer pleasure he was giving you, only pulling away after he glanced up and saw them. He immediately pulled your body into his chest and kissed the tear tracks from your cheeks, hushing you softly. You took a shaky breath as he laid you down on your back, hovering over you. His eyes raced over your curves and features, fingers tracing your Cupid’s bow as he pressed kissed to your lips and neck. He sucked another hickey, this time very noticeably on your neck; the boy had to have an obsession with marking, you decided, not the least bit upset by that fact. Your eyelids slid close as his mouth worked over your neck, your hand sliding down his chest to his hips, sliding over his briefs to brush against his member.
He let out a soft groan, his hips rocking into your hand begging, wanting for more touch. You massaged him over his too tight briefs, wanting nothing more than to give him relief and feel him inside you. Your lips brushed against his ear as you whispered softly, “I want you so bad, Jaehyun.”
You felt him shiver above you, his hands already traveling from your hips to the waistband at his. He seemed to tower above you as he slid his briefs off, allowing you to stare as he kneeled above your body. You took in his lean muscles, your nails softly raking down his chest which caused him to release a shaky breath from the feeling. Your soaked heat throbbed at the sight of his erect member that weeped precum, your body already ready to feel another release.
Acting purely out of lust and a little bit of instinct, you pushed him off of you and turned around, getting on your hands and knees. You immediately felt his hands on your hips as he bent over your body and pressed open mouth kisses to your back. Seeing you like this somehow sobered Jaehyun up, his lips moving softly against your skin as he murmured, “Are you sure, ______?”
You could tell by his voice that he was making sure this wasn’t going to be something you would regret or try to brush off. You felt commitment and real affection in Jaehyun’s touch, which reassured you and gave you hope for what would come out of all of this. You were definitely sure, “Yes, I trust you, baby.”
You felt a smile against your skin, the feeling of the atmosphere suddenly so much more intimate and romantic as he teased your opening with the tip of his member. You breathed out to steady yourself as he carefully pushed into you, your walls already so tight around him. Jaehyun groaned at the satisfying feeling, his hands that gripped your hips squeezed you tightly. You let out a gasp, the same emotions washing over you as well as he slid in to the hilt easily. You felt connected, complete.
You urged him to move by rocking back into him, his hips rolling into you as you gave him your approval. The warmth of the day was nowhere close to the burning heat you were feeling now, the way Jaehyun’s hips snapped into you as he pummeled your core left you completely star struck. You could feel him panting against the skin of your back as he drove his cock deeper and deeper into you. Minutes felt like hours as he fucked you into pleasurable oblivion, his stamina impressive. When his thrusts became more eratic, you reached down to rub your clit, hips pulled by his warm hands to fuck back against him.
His velvet voice sounded tight as he groaned, “Baby girl, you’re gonna make me come.”
As he spoke those words, you couldn’t help but almost release; every time he opened his mouth your body practically shook. Your walls slid around him, tightening as you neared your second high of the night, “Ah!…”
“Fuck!,” he cursed, releasing his hot seed inside of you, his head thrown back as you came as well. Your arms have put underneath you and your face pressed deeply into the sheets as Jaehyyn groaned above you, his hips rocking ever so slightly to prolong his orgasm. Your body felt on fire, hair sticking to your forehead as he pulled out of you gently.
Your mind was a complete blur as Jaehyyn carefully cleaned you up, pressing kisses as he made you comfortable, hardly realizing that you were laying in his arms. He played with your messy hair, untangling the knots left by him during his passion as he hummed soothingly. As your head cleared, you attempted to think of something to say, anything really. The entire situation was whack, to say the least. You just had sex with your neighbor, after masturbating with him, and having only really talked to him a few times in the hallway. You were crazy and your skin was heating up at the fact that you had tricked yourself earlier into thinking he might have real feelings for you.
Disappoint began to seep into your bones as you turned to him, afraid to make eye contact with his burning gaze. You might as well break the silence, get it over with and rip it off like a bandaid. Mustering up the courage, you murmured his name, “Jaehyun.”
“Hm?,” he hummed, fingers now tracing your nose and cheekbones. His sweet actions hurt you, knowing that they honestly meant nothing. He looked up at you expectantly, eyebrows raised in curiosity as he saw you preparing yourself like you were about to give him a speech or lecture.
He was just being polite.
“You-,” you started horribly, stuttering as you tripped over your own words, “L-listen, I-”
“_______.” He stopped you, pushing a lock of hair behind your ear. You bit your tongue as he spoke up, gentle and reassuring, “Don’t worry about it. It’s okay.”
You felt like you were burst into tears at any moment, those words of his only adding to your false hope. Your lip quivered, “It’s not okay though.”
“No, it is,” he cupped your cheek, drawing you impossibly closer into his arms. His dark eyes suddenly changed, a nervousness penetrating them as his entire counternance shifted and something so innocent and puppy-like was left behind. You watched as he bit his lip and looked away from you, his voice soft, “Can I tell you something?”
You were confused, but nodded anyway as he propped himself up on his elbow. He picked at your bedding anxiously, “This isn’t how I wanted it to happen.” Jaehyun breathed out deeply, almost in an annoyed huff, “I wanted to take you out for coffee, go to my favorite book store, show you the best record shop this side of the city…but that didn’t happen.” He flopped onto his back, passing a hand over his face as your jaw practically dropped to the floor, “But I went and rushed it, all because I was fucking horny and knew you were probably listening…”
He rolled his eyes, “I’m literally such a dumb ass. I hope you’ll forgive me because I really really like you, ______.” He glanced over at you and his eyes widened at your shocked expression, “What?”
“You mean it? You mean all of it?,” you whispered, heart racing as he turned towards you again.
“Of course I do, baby girl,” he replied, a small smile lifting the corners of his soft lips. You mirrored his look when you noticed his dimples poking out, begging for you to give them a kiss.
And you did, just because you could.
He laughed a beautifully melodic laugh, his eyes smiling, hair messy, with dimples framing his face as he pressed kiss after kiss to your body. Honestly, you still couldn’t believe your luck. Or was it luck at all? Jaehyun couldn’t believe it either as you snuggled into his chest and drifted off to sleep feeling content and peaceful. Everything was changing from here on out, and it definitely was for the better.
