The lack of actual boy next door fanfic for Boynextdoor is harrowing...

You did not hate your childhood. In fact, you would venture to say that you should look quite fondly of most of it because most of it had taken place here- in a picturesque wasteland of suburbia, and as you drive through the narrow main road, staring at glimpses of childhood relics, you begin to frown. Every memory was so unequivocally perfect except, maybe, for the ones containing him.

"Can you at least try to sound like you're not going kill yourself while you’re there?" Your best friend's voice drones on from the car speaker. Her words, no matter how valid, elicit an eye roll from you, effectively stopping your journey down memory lane. "It would be awful to have to drive down to your childhood home just because you tried to kill yourself, I refuse to have that be the way you introduce your college best friend to your mother."

"Relax," you affirm in a voice groggy from underuse. Spending an entire 15 hour drive beguiled to your car without any company except for maybe of course your Destiny's Child album and a swelling sea of dread in the pit of your stomach.

This would be the first time in a year that you were visiting your childhood home since you left for college. The first time anyone who mapped the outline of your childhood, would perceive you as the budding, blossoming, depressive adult you have become. You felt like a storm coming back into your picturesque childhood neighbourhood, threatening to sweep everything away. That feeling of dread only doubles when your driveway appears on the bottom of a hill. The cul-de-sac of your childhood with all its trimmed hedges, neat fencing and constantly perfect shudders, sends you hurtling into nostalgia and once again, common ordinary dread.

"What If I just turn the car around right now, would that be bad?"

"I have never met a college student so unhappy to be home-" Your best friend mumbles, "You're going to be living the dream!? Actual balanced meals!? Please take one for the team,"

Almost immediately, her words trigger a rumble of hunger from your stomach and you groan as your car curls into the cul-de-sac. Your heart is hammering in your ear, not for the reasons anyone might think, but because of those memories locked in your childhood. As you drive, you try to keep your eye on your house. Your perfect homely house.

Your eye doesn't even stray to the house beside it!

Honest to God!

Not even once.

"Is there a reason you don't wanna go home so bad?"

"The weather is so bad," you say almost automatically, "I think the line's about to cut,"

"Bitch, you only avoid my line of questioning like this when it's about some dick-"

"Jeez, the weather’s messing with the connection."

"If you drop this call TRUST you will be dealt w-"

"I'll call when I unpack, love you-" when you drop the call, your car is parked in the driveway and your shoulders are slumped over. You contemplate waiting around in the driveway until some relative forcibly pulls you out but that thought is quickly made obsolete when you hear a harsh knocking on the door. Your stress levels gravitate to an all time high as you watch him, waving frantically at you from the other side of the glass. His smile is bright and just as crooked as ever. His wave is frantic and energetic; Jaehyun is practically bouncing on the balls of his feet, so unequivocally happy to reunite with his childhood best friend.

His only friend. The return of that voice in your head is one of things you had been anticipating on this trip. Mainly because your childhood had been riddled with so much self esteem issues, your feelings practically metamorphosed into that voice you now hear now. That's all you'll ever be to him. All you've ever been, Your mind remarks in a distasteful spit of venom.

"Get your face off of my windows unless cleaning my car for the foreseeable future is a job you're actually interested in." You say coolly as you slide out of the vehicle. Jaehyun gives space for you to stretch, all while shuffling from one foot to the next, picking at the sleeves of his flannel with a dopey smile like he was one second away from proudly telling you he 'frew up at school'.

"Still as homicidal as ever." He says your name with a familiarity that nearly knocks you unconscious. You focus on lifting your arms to the air, and ironing out tje various aches in your back.

"How long has your ass been waiting here anyway?" It's Jaehyun's turn to nearly evade eye contact at your question. He finds it exceedingly difficult to follow along with what you're saying when you so very clearly have boobs now.

"Since my mom told me you'll be back,” He says before immediately adding, “hey- how long have those been there?" You drop your arms with furrowed brows as you look at him.

"What?"

You await a response that doesn't arrive. Jaehyun only points nonchalantly towards your chest. You look down at your v-neck and back at Jaehyun. "I don't know what you're talking about," you roll your eyes as you shuffle past him.

"YOU HAVE BOOBS NOW?!” He exclaims, “EW-"

You turn around to face him, pushing your acrylic nail into his sternum, "I've always had tits- sh-shut up-"

"You literally finished high school without them. I would have noticed as the tiddy connoisseur, trust me."

You find yourself embarrassed, not by his avid teasing (this is something you've been forced to deal with every single day of your childhood and adolescence,) but you find your stomach warming for completely different reasons. Your Jaehyun-obsessed brain wants to pick apart and dissect his entire statement. Maybe he's finally noticing you now? Maybe this age-old crush will evaporate and metamorphose into something else.

You cannot speak because your nail is still digging intently at his sternum and he's staring down at you, as if waiting for whatever venom laced comeback you had waiting for him.

All you're able to focus on however, is the way in which you're staring intently at each other. For him, this proximity is probably nothing, but for you... "Also when you get in there, please for, the love of God, act surprised."

The spell is immediately broken and you're once again brought back down to earth.

The cul-de-sac.

The driveway.

The afternoon sun, surrounded by a cooling breeze.

"Please don't tell me I'm about to walk into another family dinner," your eyes grew heavy with fatigue at just the mere thought of all your family dinners before. 'Family' being used very loosely because he always somehow found himself in every single one.

"You know how our moms can get," you did. You really did.

"Ugh," you exclaim, trudging up the house steps, "1 hour of this and I'm done." Your hand pauses before the doorknob and you turn to Jaehyun with a bored, almost questioning stare. "Aren't you gonna get my things?"

His grins a wolfish grin before clutching at the t-shirt under his flannel, "Oh how I've missed being bossed around by you-"

"Fuck you-" You chuckle out. Jaehyun only turns his torso sloppily as he continues walking to your car.

"A guy could hope!"

And just like that, that smile is gone. The moment is sour. Because whatever he meant, you knew from childhood experience that it did not mean what you wanted it to.

-

Meeting everyone all at once had been as jarring as you expected it to be. You ceremoniously heeded Jaehyun's advice, acting so completely shocked when your relatives and Jaehyun's family yelled 'Surprise' in unison. Everyone was sporting smiles that crinkled their eyes and arms open for hugs. Before you were made privy to every line of questioning surrounding school, Jaehyun's mom swept you into her arms.

"How's is my daughter in law-" there was no time for her to watch you grow tense at her words because Jaehyun who was lugging your luggage in, calmly affirmed, "She has tits now, apparently-"

"MYUNG JAEHYUN-"

The evening had progressed with all the domesticity that you lacked during college and you found yourself at immense ease throughout dinner. Home is still home. Jaehyun is still Jaehyun. Everything that once was, still is and you took a second after dinner to ruminate in the feelings of comfort seeping into your entire being.

That is until your mother ruined it by inserting a very unnecessary, wholly uncalled for fact during dessert drudgery.

"Any boys on campus?"

"It's campus," you snorted as you stuffed your face with malva pudding, "of course there are boys," Throughout the course of your dinner, Jaehyun, who is dutifully seated directly beside you, has taken to swinging his leg against yours. A provocation from childhood that you almost immediately latch onto until you are both playing a violent game of footsies under the table.

"No boys to smooch on campus," Jaehyun speaks up, petulantly puckering his lips at you. All you're able to do is try and ignore him which proves to be a dangerous feat.

"I should think there's a new boy." Your mom says before pointing at you and Jaehyun with the flick of her utensils, "The primary school crush you two had on each other has gone on for way too-"

"MOM!?"

Your mother's slip of the tongue instantly grabs all of Jaehyun's attention. He's perking up in his seat like a rottweiler at attention with his head snapped in your direction.

"Crush?" His eyes falter, scanning the side of your face as if he was perceiving you anew. All traces of a smile are gone as he dumbly asks "What crush?"

"I've been driving for an insane amount of hours," you begin by pushing yourself out of your dining chair, "I should unpack and get to bed-"

"W-Wait I can help." You glare daggers at Jaehyun, that look alone should be enough to stop him from rising from his seat.

"Don't be rude. Your best friend hasn't seen you in ages" your mother scolds, lightly prompting your hands to curl at your sides, "We'll take care of the dishes."

-

Your ascension up the stairs had been charged with tension and filled with something else entirely. You walk ahead of Jaehyun as if trying to distract yourself from his presence, but everything about him is so completely there, "I can feel you staring at my ass," you mumble, needing to fill the air with something, anything at all as you reach the upstairs landing. "Guilty," he says as he follows you into your childhood room which is much the same.

Jaehyun beelines for your twin bed, almost immediately flinging himself on the childish quilted bedspread. "This place is still the same..."

"So are you actually going to be useful, because if not," you fold your arms as you stare him down, "You can leave?"

His mouth hangs open in a lopsided grin as he reaches around to grab at the very first plushie he finds. One of many.

"You still sleep with these?" He asks instead, as if your question meant nothing at all. He plays idly with the stuffed dinosaur in his hands as he leans his head back against the pillows. Seeing him here, amongst your things, brought an avalanche of nostalgia and a wave of hopelessness. He is still so attractive, even after all these years.

You sigh, "Jaehyun if you're not gonna-"

"So was that true?" There it is. The shotgun question that had been hanging like damp washing between the two of you. With your nerves shot to hell, you decide to lower your behind on the very edge of the twin bed as you busy your hands with folding your clothes. Your back is turned to him but you can feel those piercing, smiling eyes watching you.

"Is what true?"

"C'mon, don't do that,'' there is a noise of shuffling behind you. Your heart hammers in its cage with the dip in the bed sheets and you can feel him seated directly behind you. You look down at your lap to find that he's placed your plushie there, as if to distract you from the fact that his legs were now framing yours, his front pressed against your back.

"You know what," he whispers straight into your ear, sounding as serious as you've ever heard him.

Craning your neck backwards to let your eyes fall on Jaehyun would prove to be a cataclysmic mistake. It only heightens the wobble in your voice as you say, "The crush I had on you was juvenile and childish and frankly didn't mean any-"

"Dude..." he whispers, eyes seemingly boring into every single square inch of your face, "I've dreamt about being your boyfriend since I fucking found out what a boyfriend is." His words knock the breath cleanly out of your lungs and your voice grows quiet as he lifts his hand to the side of your face. "What..."

"Yeah!"

His voice is loud and boisterous but you're still somehow locked tightly in your stupor.

"Nu uh," you mumble, your eyes daringly drifting across his lips, "You're lying?"

"How am I lying, angel?" you suck in a deep breath because his thumb is rubbing dizzying circles against your cheek now and his voice has descended a gravelly octave. He dips his head down, experimentally placing a feathlight kiss on the corner of your bottom lip. So innocent, but charged with so many expletives, the possibilities rush straight to your clit.

Still, you soldier on.

"B-Because remember what you said at our grade 6 dance?"

He's not listening. He's not listening because he's finally got a taste of you and he'd be damned if he didnt get more. Jaehyun cranes your neck until you're facing forward once more and you gasp when his lips descend on the skin between your neck and shoulder. "Enlighten me," he mumbles against your skin, placing more featherlight kisses there before he quickly grows bored and decides to stick out his tongue experimentally. You turn into molten clay in his hands and the whimper that escapes you is borderline pornagraphic. This is the stuff all Jaehyun's previous fantasies are made of.

"W-When you asked me out- you said..." your voice drifts off because Jaehyun can't help but let his right hand reach around until he squeezes your torso impossibly closer. All the pudge, all the skin, all the ways he's been dreaming about having you this close and you were there for the taking this whole time.

"Fuck, I'm obsessed with you…" He says, and he does a very odd thing. He buries his face in your neck and just sniffs. This momentary slip of weakness allows you to regain some of your senses as you say,

"Y-You asked me to be your date," Jaehyun is drunk on the very scent of you now and his cock throbs as he brings you impossibly closer against his lap,

"What else did I say, baby," he wants you to carry on talking. Anything that might distract you from wanting him to leave. Anything that might keep you here just a little longer. His cock throbs at that thought alone and it has him rubbing against your skin like a dog in heat.

"Y-You said you didn't have anyone else to go with-" you suck in a deep breath through your air as Jaehyun's hand venture underneath your shirt. He slithers his hand up in a hurry until his cool fingertips are grazing the flesh of your breasts. Like a crazed adolescent driven by his hormones alone, he pulls your bra down, all while tonguing and licking at your neck like his life depended on it.

"S'sorry," he mumbles incoherently behind you, and his hand on the side of your face cranes your head backwards so that you're facing him once more, "So'so'sorry," he places a sloppy, apologetic kiss on your mouth which immediately triggers a very deep desire that is almost as old as you are.

"I wanted you so bad-" you admit with a gasp, and Jaehyun feels your confession shoot straight down his spine. He plasters his front into your backside, pressing his hips against your ass in an apparent wave of lust.

"I've always needed you," he ventures to admit, pressing his bulge against your backside as if needing to persuade you further.

Those words of affirmation are all you need , all you've needed for a lifetime and you immediately turn until you're lumbering onto him before letting your knees frame his hips. His hands instinctively grip onto, your supple, full hips and the feeling of your softness on top of him alone is enough to have him groaning into the air as his hips stutter up at you.

While you crash your lips against his once more you lift yourself away but his hips follow, "The fuck are you doing!?" He mumbles against your lips before biting lightly at your bottom lip.

"Too heavy," you mumble, "I don't wanna be too hea-"

Your words dissolve in your throat and in its place, a yelp escapes as Jaehyun forcibly pulls you down onto his sweatpants-clad lap. "You did this to me," he says, watching you intently as if scolding you, "You did this to me and now you wanna run away?" He scoffs as his hands begins to guide your hips against his. You're both in very flimsy material. Him in his sweatpants and you in similar attire except your sweatpants were a dusky pink. "Youre so pretty grinding on me like that fuck-" he speaks quickly and fluidly as he leans backward onto your bed, making more space to watch you grind yourself on top of him.

His attention is utterly intoxicating and so you do nothing but listen when he says, "Take your top off, baby-"

You peel the item of clothing off, unclipping your bra with all the speed and sloppiness that came with your lust-filled fog/ Jaehyun doesn't help. He's all too focused on guiding your hips against his, watching you face contort into pleasure.

"Pants," he says, needing to see more of your open-mouthed moans, "Take your pants off," he whispers, "Make a mess on me," he swallows thickly, "Please,"

You lift yourself to momentarily push your sweatpants, Jaehyun lifts himself momentarily to grab at your stuffed animal.

"Whatre you-" When you straddle him again, you're completely naked while he's fully clothed. The juxtaposition only elicits another wave of lust. "Hold this while you ride me," he stuffs your plushie against your chest, watching your mouth hang open as you lower your clit onto his bulge,

"O-Oh my fuck, Jaehyun-"

"Just like that, angel, fuck,' he throws his head back momentsrily stumped by the weight of his pleasure. He's trying to be dominant for you. He's trying to keep his control for you, but you're moving your hips against his, with his bulge between your legs, using him for absolute filth. It ruins him entirely.

His voice cracks when he lifts his head to look up at you and say, "Oh my god, you feel so fucking good, oh my god," When Jaehyun curses, your cunt only presses down harder against him, prompting a needier response out of you.

Jaehyun swallows thickly, "Use me, baby," he says, "F-Fuck, just fucking use me," his hips stutter upwards and his hands on your sides grip you so tightly you know it'll leave marks. "Doing s-so well for me. Youre doing so fucking well-"

He watches with an open mouth at your tits, so pillowy and full, bouncing as you rub yourself against him and he completely loses it.

"Fuck- p-please cum, I need to cum so bad-" Jaehyun gasps, wracking another torrid moan out of you as you descend almost immediately into your orgasm. Jaehyun watches with an open mouth and half lidded eyes, unable to stop himself from fucking up into you. He wraps his arm against your waist and buries his face in your chest. You rake your fingers through his hair and he shivers

"No way you just made me cum in my pants," he is so incredibly overcome with embarrassment, he dreads having to look up at you.

"I'm sorry," he whispers.

"No, Jaehyun, its-"

"I mean about not being honest sooner. That was bad of me, he mumbles into your chest and you chuckle at his petulance, "I'm sorry,"

"Apology accepted for making me wait so long..."
