sparks crackled at your fingertips as you warmed your body by the fire, finding solace in the one peaceful spot on the beach. sand rested under your bare feet, and you watched as the setting sun honeyed the atmosphere. it would've been peaceful—the water, the swaying trees, the seagulls—but the horde of people littering the shore disrupted the scenery. music blasted from seemingly every direction, genres from multiple different speakers muddling together. kegs were planted in various spots, groups congregating to each one. you cringed at the thought of putting more alcohol in your system.
just as you were debating leaving, the guy you had been eyeing up all night began walking towards you. you pretended to be focused on the flames as he made his way over.
"yo." he spoke as he neared you.
"hi!" you responded, angling yourself towards him and trying to regulate your breathing.
he made it next to you before speaking again. "are you nate's sister?"
"no." you lie quickly, not wanting to be recognized as the sibling of an overprotective brother.
"ah," he sighed in relief, "well me and some people are going to the water, if you wanna come." he gestured to a multi-gendered group holding towels.
you frowned. "i would, but i didn't bring a bathing suit."
the guy ran his fingers through his blonde hair, and turned back to smile at his friends. a look of mischievousness crept into his eyes. "yeah, neither did we."
you tilted your head in confusion.
"ever gone skinny dipping?" he asked, his gaze tracing your figure.
a lump caught in your throat as you debated the answer you were going to give the guy. it wasn't quite dark enough to justify the excursion, but you didn't want to seem like you were a bore. waves seemed to lap at the shore in slow motion while you considered your options. finally, after looking at the group of restless friends, you opened your mouth to agree to go with him. but as the words began to leave your lips, a hand gripped your wrist.
"let's go." a voice demanded.
the voice was immediately recognizable, undeniably matt. you whipped your gaze to the tight grip he had on you, wriggling under his grasp.
"jesus, matt, let go of me." your squirming was useless.
you stumbled to keep up with matt's rapid pace as he tore you from the bonfire. his hold on you was firm, and you could do nothing but match the rate in which he was scaling the beach. he didn't bother to speak until you had made it to the gravel parking lot.
he released your wrist to yank open the passenger door of an old truck. "get in."
you folded your arms in front of your chest. "no, i'm not done here yet."
rolling his eyes, he gestured for you to get in the car. "i'm not letting your drunk ass go skinny dipping with a random guy."
you reluctantly posted your foot on the side step and pulled into the seat, grumbling. he slammed the door shut after making sure your feet were secure under the glove box.
"so you just listen in to all my conversations?" you mumble as he turns the key in the ignition.
"you weren't even supposed to be at this party. you're lucky i'm not callin' nate up right now."
you whisper unintelligible curse words under your breath, wiping sand from your feet.
he barely acknowledges you, and instead puts his arm around the back of your headrest. his eyes are fixed out the back window as he reverses the truck. you try not to look at the tattoos that snaked up his arm when he brought his hand back to the steering wheel.
"and i'm not drunk." you clarify, responding to his previous accusations.
"you're not even wearing shoes."
you stayed silent the rest of the drive, attempting to focus on the road ahead. it was common—this behavior from matt. being your brother's best friend, he harboured the same overprotectiveness that you despised from nate. having one controlling sibling you could handle—but two? your brows crumpled together as you thought about the opportunity matt stripped from you. why did he think he had some sort of authority over you? but more importantly; why did this authority always work? what was it about him that made it impossible to disobey?
it was when the car went into park that you got more aggravated.
"you're not coming in." you say, the comment half question and half hope.
he turned to you, elbow resting on the centre console. the distance between the two of you shrunk as he leaned in closer, your body instinctively going rigid. you dart between each of his eyes as he inched nearer to you. the corner of his lip curled upwards as you hear a click—the sound of him unbuckling your seatbelt. matt sunk back in his seat and watched as the strap retreated up your chest.
"yes i am."
you released the breath you didn't realize you were holding. "why are you always sleeping over?"
ignoring your comment, he opened the door and left you to regain your thoughts. desperate to seem like the closeness hadn't affected you, you left the truck and trotted to your front door. by the time you made it inside, matt had already disappeared up the stairs, presumably to your brother's room.
the sky had darkened during your impromptu car ride, and the clock on the stove flashed a reasonable bed-time. you saw nothing better to do than go to sleep, and made your way to your bedroom. after your teeth were brushed, and you had gotten into a comfortable pajama set, you tucked yourself under your silk sheets.
relaxing should've come easily to you, after the long day you had. but tossing and turning ensued when all you could focus on was matt being a wall away. he was with nate more often than he was without him, staying over at your house multiple times a week. it baffled you how someone would voluntarily spend that much time with your brother. they were so attached at the hip that you rarely interacted with matt alone, but when you did, you couldn't deny you liked it. you put on a facade, of course, that being in the same room as him was god-awful. but in reality, your heart fluttered a little every time you were alone. his end of things, however, was not a facade. he acted as though any conversation with you was a chore. you would be delusional if you convinced yourself he got the butterflies too.
the next few hours were completely restless. you clamped your eyes together in an attempt at convincing yourself you were asleep, but it was useless. your body betrayed you, forcing you awake every time your lids felt heavy. eventually, when you realized it was hopeless, you sat up. running both hands down your face in defeat, you swung your legs to the side of bed. your fuzzy carpet brought you a sense of comfort, at least.
maybe if you made some tea…or warm milk—what is it that people drink to sleep? you slumped down the stairs on a lazy mission, using your phone flashlight to illuminate the way. when you reached the kitchen, a small clinking noise was disrupting the silence of the night. whipping your hand to the sound, you were met with the culprit. matt was sat at the dinner table, a spoonful of cereal reaching his mouth.
"jesus, turn that off!" he winced, his hand shielding the light.
you flipped your phone off quickly, apologizing. "matt! sorry, i didn't know you were up."
you became hyper aware of your touselled hair and the shorts that fell just past your ass. while you subconsciously smooth your clothes, matt just focuses on you, chewing his cereal.
"couldn't sleep?" he asks once he swallows.
you grumble. "something like that. you?"
"hungry."
staring at the microwave, you read the flashing numbers. "it's 3 am."
"a mans gotta eat."
suppressing a smile, you reach the cupboard where the tea was kept. rifling through the boxes, you pull out a chamomile, and flip on the kettle. as you're tearing open the packet, you hear the sound of a chair squeaking out. your eyes had now adapted to the darkness, and you watched as matt curved past the island to the sink. you had to physically restrain yourself from watching his soap coated hands as he washed his dish.
"you gonna go back to bed?" he questioned, drying off his hands.
you poured the steaming water into a mug as you replied, "i'm gonna try."
shrugging, he said, "you just need something to tire you out."
you shot your eyes to him, squinting in confusion. a small smirk tugged at his lip in response. you tried not to let your mind spiral at his words, but it was ineffective. how could such a little sentence make your heart stop?
he must've seen the effect it had on you, because he shook his head. "i didn't mean it like that."
"mean it like what? you played dumb.
"didn't mean for that to come off so… sexual."
"i don't mind."
he cocked his head. "yeah?"
you stared down into your stagnant tea, your fingers tapping on the ceramic as you held it in both hands. from above the rim, you saw him advanccing closer. why did you say that? he probably thought you were just another girl, thirsty for his attention. if you were that or not—you still hadn't figured it out. when you raised your head, he was close enough to you that you could smell his spiced, woodsy cologne. taking a step forward, matt's eyes traced down your skimpy outfit. the fact that you weren't wearing a bra snitched on you, your nipples hardening under the thin fabric. one of his hands curled to the small of your back, while the other gripped your mug. he set it down on the marble as he backed your ass against the counter.
"y'know…" he started, bringing his hand to hold the curve of your waist, "seeing as you don't mind… i could help."
you gulped, the cool material shocking you through the back of your shorts. "help with what?"
he brought his face closer, brushing past a strand of your hair as his lips made it to your ear. "tiring you out."
the deep whisper sent vibrations through your body, and matt watched as goosebumps rose on your skin. you try not to blush under his stare.
"matt.." your voice came out quieter than you wanted.
"say my name again." his hands were now on either of your thighs, eliciting more shivers.
in one swift motion you were on the counter, matt's waist in between your legs. his clothed hardness rubbed against the sheerness of your shorts, causing a soft whimper to leave your lips. his eyes, filled with a sense of hunger, rapidly flit between each of yours. he craved hearing your noises—you could tell by the lust radiating off of him. and you were now in a place where you wanted to give him whatever he desired.
"matt please.." you pulled at the strings of his sweatpants, until his bulge was flush against your covered clit.
his dick twitched at your words, and the added stimulation of you against him.
"please what, baby?"
"fuck me." the words felt filthy, unrecognizable, as they left your mouth.
his next movements were leisurely, deliberate. he backed up just enough to pull your bottoms down, and was met with the fact that there was no more fabric to take off.
"no underwear?" he dragged his hand down the lower half of his face. "fucking slut."
your bare pussy clenched around nothing, desperate for friction. he caught wind of your upturned, needy expression, and that only fueled his desire. when he pulled down his pants and boxers just enough, you got to see this desire. reddened, throbbing, and held firm in his hand, his cock leaked precum. he stroked down himself, slow enough to allow you to revel in the sight. you unknowingly bit your lip, relishing in the size of him.
a cocky smile plastered on his face. "think you can take it?"
you nod hesitantly.
"i'll make sure you can, just be a good girl and let me do the work."
he traced his dick down your folds, using his tip to bring the increasing wetness to your clit. you wriggled closer to him, to which he held you steady with a palm to your thigh. his motions were achingly laboured, like he wanted to draw out the situation as long as possible. you weren't sure how long you could stand having him teasing you, so you squirmed again.
he tuts at you. "patience, baby. you'll get what you need."
this is the kindling to the fire, and only makes you crave him more. he sees this in your eyes, and decides to let you have what you wanted most. he lined his cock to your entrance, and watches as it disappears in your walls inch by inch. you make a sound, something between a whimper and a sob, as he reaches half way.
"fuck—you're so tight." matt groaned, pushing in deeper.
your mouth fell agape, and he took the opportunity to press his lips to yours. it was messy, passionate, and his cock buried further as he deepened the kiss. moans choke from your mouth into his, and you wrap your legs around his waist. he fixes the entirety of himself inside, and you savour the feeling of his raw length in your pussy before he starts moving. the thrusts began in an intentional manner, a lazy pace set to let you get used to the sensation. but the lewd sounds that escaped your throat made it impossible for him to keep that steadiness.
"oh god." you breathe, throwing your head back.
he takes your exposed skin as an invitation, latching his lips to the side of your neck. simultaneously reaching under your shirt he cups your boob, and works your nipple between two fingers. you covered your mouth in a lousy attempt at muffling your cries.
replacing his lips with his hand, he grips your throat. "you like that, huh?"
"yes—fuck—so good."
one of matt's hands stays on your neck, while the other travels to where the two of your bodies met. his thumb circles your clit, adding agonizing sensations throughout your body. you try to hold onto anything you can—the lip of the counter, his back, his biceps. you were in disarray, the messiness of his strokes doing nothing to aid your broken mind.
matt's fingers move up from your throat to cover around your mouth, adding much-needed insulation for your noises. but his own gradually grew louder, the low huffs sending you over the edge. he pounded into you relentlessly, the cool marble sliding under your ass with each thrust. the continuous rubbing of your clit, his palm restricting your words, it was all too much. you felt your release coiling low in your stomach.
he felt the clench of you around him, and slowed slightly. "not yet."
you whined, chasing your orgasm. "please, matt—i'm so close."
he continued the merely reduced pace. "you can wait jus' a little longer, can't you baby?"
"i—i don't know."
"try for me."
fighting your release was made more difficult the moment his mouth met yours again. the fullness of your pussy around his cock paired with your tongues tangling together made you incoherent. the only sounds you could get out were choked gasps, which made completing the kiss impossible.
"i know baby, i know." he cooes.
all your energy went into obeying him, and keeping yourself from cumming.
"you're doing so well for me, pretty girl."
you begged one last time, and he couldn't resist giving in after looking at your flushed face.
"yeah? you wanna cum on my cock?"
you nod, no words coming out.
"cum around my dick like a fucking slut."
moans spilled from your lips as you allowed yourself to come undone. a wave of pleasure rushed over you, shivers cascading down your legs as you clenched around his length. he didn't let up, but instead increased the rhythm. the sound of his sloppy thrusts enveloped the room, your growing wetness seeping down his cock. his noises—deep, husky, velvety, they worked you through your orgasm. after one last jerk into your core, you felt hotness seeping inside of yourself. tightness creased around his eyes as he rested his forehead on yours, panting. he held himself inside of your walls, both of your mouths gasping against one another.
needless to say, that night you had the best sleep of your life.
a/n ☕️: this is based on multiple scenes from the kissing booth movies 😭 i am a SLUT for the “they both couldn’t sleep and they ended up in the kitchen together” trope, it hits EVERY TIME.
