The Secret Folders - Or Surprisingly Exposed

Seulgi x Male Reader

word count: 4.5K

The horror movie flickers across the TV screen, casting dancing shadows around Seulgi's dimly lit living room. But you can barely focus on the generic slasher plot - not with her sitting so close beside you on the plush leather couch. Your best friend since college is wearing those damn gray pajama pants again, the ones that hug every curve of her toned legs and petite frame. Combined with a loose t-shirt that's always sliding off her shoulder, giving a glimpse of her collarbone; she's the perfect mix of casual comfort and unintentional sexiness that's been driving you insane lately.

"Earth to spacehead," Seulgi says with a playful nudge, breaking you from your wandering thoughts. "That's like the third time you've jumped at absolutely nothing. The movie's not even at a scary part yet."

You force what you hope is a casual laugh, hyper-aware of how her half-bare shoulder brushes against yours as she shifts position. "Just tired I guess. Long week at work and all that."

"Bullshit," she counters with that knowing half-smirk that makes your stomach do backflips. "I've seen you marathon horror movies until 4 AM after double shifts. Try again."

"Maybe I'm just getting old and jumpy?" You attempt deflection, but your voice comes out higher than intended.

Seulgi pauses the movie mid-scene, turning to face you fully with her legs tucked under her.

"Or maybe," she draws out the words slowly, dark eyes studying your expression, "you're distracted by something else entirely. Or should I say... someone?"

Your heart rate kicks up several notches. There's a glint in her eye that you've never seen before - something predatory and knowing that makes your mouth go dry. "W-what do you mean?"

"Oh, I think you know exactly what I mean." She leans in slightly, her vanilla-scented shampoo filling your senses. "See, the other day when I borrowed your laptop to print those work documents? I may have accidentally stumbled across some... interesting folders."

The blood drains from your face as realization hits.

Fuck.

Those folders.

The ones you thought were safely buried in obscure subfolders with innocuous names. The ones filled with carefully edited split-screen videos - porn on one side, usually featuring petite Asian women who looked just like...

"Your face is doing that thing it does when you're panicking," Seulgi observes, seeming almost amused by your deer-in-headlights expression. "The same look you had that time we almost got caught sneaking into the campus pool senior year."

You open your mouth to speak but no words come out. How do you explain away folders full of porn videos meticulously edited to display alongside photos of your best friend? There's no platonic explanation for that level of obsession.

"I have to say," she continues casually, as if discussing the movie rather than your darkest secret, "I'm a little hurt you didn't just tell me you were into me. We've been friends for what, six years now? That's a long time to keep those kinds of feelings bottled up."

"Seulgi, I..." you start, then falter. "I never wanted to mess up our friendship. You mean too much to me to risk that. And I know those folders were fucked up. I promise I'll delete everything! I'm so sorry you had to see that-"

"Shh." She presses a finger to your lips, effectively silencing your rambling apology. "I'm not finished. Because while I was surprised to find those folders... What surprised me more was realizing how much they turned me on. Damn, I didn't know you were such a dirty boy."

Your brain short-circuits at her words, unable to process this turn of events. Seulgi takes advantage of your stunned silence to slide closer.

"Want to know a secret?" she whispers, her lips barely an inch from your ear. "I've thought about you too. All those times we've had sleepovers, sharing my bed... I'd lie awake wondering what would happen if I just rolled over and kissed you. If I told you how wet I get when you look at me with those hungry eyes you think I don't notice."

"Fuck," you breathe out shakily as her hand lands on your thigh, fingertips tracing idle patterns through your sweatpants. "Is this really happening?"

"That depends," she replies with mock thoughtfulness. "Do you want it to be happening? Because I saw those videos you like... all those pretty Asian girls taking it up the ass... is that what you want to do to me? Do you want me to be your anal princess?"

Your grip on the couch cushion tightens as arousal shoots through you at her blunt words. Hearing your best friend talk like this is driving you crazy.

"Don't worry, I always wanted this too," she continues, voice dropping to a husky whisper. "Do you remember all those times I'd sit in your lap for no reason? When I'd 'accidentally' grind against you while reaching for something?" She grins wickedly. "That wasn't accidental at all. I've been trying to make you hard for months."

Your mind races back through countless moments - Seulgi plopping down on your lap during movie nights, wiggling her tight little ass against your crotch as she "got comfortable." How many times had you gone home afterward to jerk off thinking about it?

"I could feel it, you know," she continues, her voice dropping lower. "How hard you'd get. Sometimes I could even feel your cock twitch through your pants. It made me so wet knowing I was affecting you like that."

You groan, unable to help yourself. "Fuck, Seulgi..."

"And you know what really got me hot?" She leans in close, her lips brushing your ear. "Sometimes I could feel your cock right against my asshole through our clothes. The way it would press right there... god, it made me want to just pull my pants down and let you fuck my ass right then and there."

Your cock is straining painfully against your jeans now as Seulgi's dirty confession pours out. She notices, of course, and presses her palm firmly against your bulge.

"You still haven't answered me: all those videos you picked - they were all anal scenes. Is that what you think about? Fucking my tight little ass?"

Unable to form words, you just nod. Seulgi's hand squeezes your cock through your pants.

"Tell me," she demands. "I want to hear you say it."

Swallowing hard, you force yourself to meet her intense gaze. "Yes. Fuck yes! I think about your ass all the time. Every time you wear that fucking leggings, I can see every curve, how tight and perfect it is. I go home and jerk off thinking about spreading those cheeks and burying my cock in your ass."

Seulgi moans, grinding the heel of her hand against your erection. "Keep going. Tell me more."

The dam breaks and all your pent-up fantasies come pouring out. "I think about eating your ass first, getting it nice and wet with my tongue. Spreading you open and licking you until you're begging for my cock. Then sliding into that tight hole inch by inch while you take it all..."

"Fuck," Seulgi gasps, her free hand sliding between her own legs. "I knew we had a connection. Want to know a secret?"

You nod eagerly, hypnotized by the way she's rubbing herself through her pants.

"I have toys," she confesses. "Butt plugs, dildos... I use them in my ass almost every night thinking about you. Imagining it's your thick cock stretching me open instead."

That confession breaks the last of your restraint. With a growl, you grab Seulgi and pull her into your lap, crushing your lips together in a desperate kiss. She responds immediately, grinding her ass against your cock as her tongue invades your mouth.

You grab her firm ass with both hands, squeezing and spreading the cheeks through the fabric. Seulgi moans into your mouth, rolling her hips to create more friction.

"Bedroom," she pants, breaking the kiss. "Now. I need you to fuck my ass properly."

You don't need to be told twice. Standing up with Seulgi still wrapped around you, you carry her down the hall to her room, hands firmly gripping her ass the whole way. She attacks your neck with kisses and little bites that make your cock throb.

Once in her bedroom, you toss her onto the bed and she bounces with a giggle that quickly turns into a moan as you grab the waistband of her pajama pants and yank them down. Her tiny black thong comes with them, leaving her lower half completely exposed.

"Fuck, look at that ass," you breathe, taking in the sight of her small, perfectly round cheeks. You've imagined this view countless times, but reality is so much better.

Seulgi wiggles her hips teasingly. "Touch it. I've been waiting so long to feel your hands on me."

You don't hesitate, climbing onto the bed and running your palms over the smooth globes of her ass. Her skin is incredibly soft and warm under your touch. You squeeze and knead the firm flesh, spreading her cheeks to reveal her tight pink hole.

"God, it's perfect," you groan, rubbing your thumb over her puckered entrance. Seulgi pushes back against the touch with a whimper.

"Taste it," she demands, arching her back to present herself better. "I want to feel your tongue in my ass."

You dive in eagerly, spreading her cheeks wide and dragging your tongue from her dripping pussy up to her asshole. Seulgi cries out, pushing back against your face as you circle her rim with firm licks.

"Yes, fuck, just like that," she moans. "Get my ass nice and wet for your cock."

You alternate between broad licks and pointed jabs with your tongue, gradually working the tip past her tight ring of muscle. Seulgi's whole body shudders as you tongue-fuck her ass, her pussy dripping onto the sheets below.

"More," she begs. "Stick your tongue in deeper. Get me ready for that thick cock."

You redouble your efforts, gripping her ass cheeks hard enough to leave marks as you bury your face between them. Your tongue pushes deeper into her hot channel while your nose presses against her taint. The musky, intimate taste of her ass only makes you harder.

Seulgi reaches back and spreads herself even wider for you. "That's it, eat my fucking ass. God, I've dreamed about this so many times."

You pull back just enough to spit directly onto her hole, watching it clench and relax. "Me too. Every time you sat on my lap, I wanted to bend you over and tongue-fuck this perfect little ass."

"I knew it," she pants. "I could feel how hard you'd get. Sometimes I'd grind back extra hard just to feel your cock pressing against my asshole through our clothes."

You press your thumb against her spit-slicked entrance, watching it slowly sink in to the first knuckle. Seulgi moans and pushes back, taking it deeper.

"Look how eager your ass is," you tease, working your thumb in and out. "Such a greedy little hole."

"Only for you," she gasps. "I've been saving my ass for your cock. Now stop teasing and fuck me already."

But you're not done exploring yet. You've fantasized about this too long to rush it. Pulling your thumb out, you replace it with two fingers, slowly working them into her tight channel.

"Fuck yes," Seulgi hisses. "Stretch me open. Get me ready for that big dick."

You pump your fingers steadily in and out of her ass, watching in fascination as her hole grips and releases them. Your other hand slides around to find her clit, rubbing the swollen nub in time with your thrusts.

"Oh god," she moans, rocking between your fingers. "That feels so fucking good. Add another finger, please. I want to be nice and loose for you."

You comply, working a third digit into her stretched hole. Seulgi's back arches beautifully as she takes it, a long moan escaping her lips.

"Such a good girl, taking it so well," you praise, scissoring your fingers to open her up more. "I can't wait to feel this tight ass wrapped around my cock."

"Please," she whimpers. "I need it. Need your cock in my ass so bad."

You continue finger-fucking her ass while your other hand works her clit, building her up slowly. Seulgi's moans get higher and more desperate as she approaches orgasm.

"That's it," you encourage. "Cum for me. Cum with my fingers in your ass."

Seulgi's whole body tenses as she crashes over the edge, her ass clenching rhythmically around your fingers as she cums. You work her through it, only stopping when she collapses bonelessly onto the bed.

"Holy fuck," she pants, looking back at you with glazed eyes. "That was so good."

You slowly withdraw your fingers, admiring how her hole stays slightly open. "Just wait until you feel my cock in there."

"Yes please," she purrs, rolling onto her back. "But first, get naked. I want to see what I've been missing."

You quickly strip off your clothes, your cock springing free rock hard and leaking. Seulgi's eyes go wide as she takes in your size.

"Fuck, you're bigger than my toys," she says appreciatively. "No wonder I could feel you so well through your pants."

She sits up and pulls her t-shirt off, revealing small, perky breasts with hard nipples. Your mouth waters at the sight of her toned body, tight abs leading down to her bare pussy.

"Come here," she beckons, reaching for your cock. "Let me get you nice and wet first."

You move closer and Seulgi wraps her small hand around your shaft, stroking slowly. Pre-cum leaks from the tip and she uses it to lubricate her movements.

"I've wanted to touch your cock for so long," she admits, leaning in to lick a stripe up the underside. "Every time I felt it getting hard under me, I wanted to pull it out and suck it."

Her tongue swirls around the head before she takes you into her mouth. You groan as she sucks you deeper, her hand working what doesn't fit.

"Fuck, your mouth feels amazing," you pant, threading your fingers through her hair.

Seulgi hums around your cock, the vibrations making your legs shake. She works you expertly, alternating between deep throat attempts and focusing on the sensitive head.

After a few minutes of this heavenly torture, you have to stop her. "Wait, I don't want to cum yet. I want to save it for your ass."

She releases you after a long suck on the tip. "Mmm, yes please. I want you to cum deep in my ass."

Seulgi rolls over onto her hands and knees, presenting her ass to you once again. "I need your cock in my ass so bad, babe. The lube is on the nightstand."

You grab the bottle and drizzle it generously over her hole and your cock. Using your fingers, you work it into her ass, making sure she's well-prepared.

"Ready?" you ask, lining yourself up with her entrance.

"God yes," she moans. "Fill my ass with that big cock."

You press forward slowly, watching the head of your cock stretch her tight ring of muscle. Seulgi whimpers as you breach her, her hands fisting in the sheets.

"You okay?" you check, pausing to let her adjust.

"Yes, don't stop," she pants. "Keep going. I want all of it."

You continue pushing forward inch by inch, groaning at the incredible tightness of her ass. Seulgi rocks back slightly, helping to work you deeper.

"Fuck, you're so big," she gasps. "My ass feels so full."

Finally, you bottom out, your hips pressed flush against her ass cheeks. You both moan at the sensation of being completely joined.

"How does it feel?" you ask, running your hands over her back.

"Amazing," she breathes. "Better than I ever imagined. Start moving, please. I need you to fuck my ass."

You pull back slowly until just the head remains inside, then push back in at the same pace. Seulgi's ass grips you like a vice, sending waves of pleasure through your body.

"God, your ass is perfect," you groan, establishing a steady rhythm. "So fucking tight around my cock."

"Yes, fuck my ass," she moans. "Use my tight little hole. I've been saving it just for you."

You gradually increase your pace, watching in fascination as her ass swallows your cock over and over. The sight of your shaft disappearing into her stretched hole is hypnotic.

Seulgi reaches between her legs to play with her clit as you fuck her ass. "Harder," she demands. "I can take it. I want you to really fuck me."

You grip her hips tighter and start pounding into her ass with more force. The sound of skin slapping against skin fills the room, mixed with both of your moans and gasps.

"Yes, just like that," she cries. "Fuck my ass hard. Make me your anal whore."

Her dirty talk spurs you on and you slam into her even harder, watching her small body jolt with each thrust. Your balls slap against her pussy, adding to the obscene symphony of sounds.

"You like that?" you growl, spanking her ass cheek. "Like having your tight little ass stretched around my cock?"

"God yes," she pants. "I love it. Love feeling you so deep in my ass. Don't stop, please don't stop!"

You can feel her getting close again, her ass clenching rhythmically around your cock as she works her clit faster. The extra tightness is bringing you closer to the edge too.

"Gonna cum soon," you warn, your thrusts becoming more erratic.

"Inside," she begs. "Cum in my ass! Fill me up with your hot load."

The combination of her words and her tight ass proves too much. With a final deep thrust, you explode inside her, painting her walls with rope after rope of cum. The feeling of being filled triggers Seulgi's own orgasm and she screams your name as she cums hard around your cock.

You continue pumping slowly, working both of you through your climaxes until you're completely spent. It's when you collapse forward, careful not to crush her smaller frame. Both of you pant heavily as you come down from your respective highs.

"Stay inside me," she murmurs when you start to pull out. "I want to feel your cum in my ass as long as possible."

You comply, remaining buried in her stretched hole as it continues to pulse around your softening cock.

"Fuck, that's hot," you groan, bringing your face closer to kiss her neck. Her tight hole squeezes you and you can feel your cum starting to leak out around your shaft.

"I can't believe we finally did this," Seulgi says softly, turning her head to look at you with those beautiful eyes that always drive you crazy. "I've wanted you for so long..."

"Really?" you ask, genuinely surprised. "I had no idea. I mean, I've always been attracted to you too but I figured I wasn't your type."

She lets out a little laugh. "Are you kidding? You're exactly my type. I've been fantasizing about you fucking me like this for years." She rolls her hips slightly, making you both moan as your semi-hard cock shifts inside her cum-filled ass.

"Why didn't you ever say anything?" you ask, running your hands up and down her smooth back.

"Same reason as you probably - didn't want to risk ruining our friendship," she admits. "Plus I wasn't sure if you saw me that way. I mean, you were always so shy, never showing any obvious interest, despite your glances at me... It was hard to decipher what you really wanted."

"Well, now you know what I really want. Do you know how many times I've jerked off thinking about that perfect little ass of yours?" You give her ass cheeks a squeeze for emphasis. "Or those cute little tits? Or those fucking gorgeous lips wrapped around my cock?"

Seulgi moans softly at your words, her ass clenching around you again. "Mmm tell me more... What else did you think about doing to me?"

You can feel your dick starting to harden again inside her as you continue: "Fuck, everything. Bending you over every surface in my apartment. Watching you bounce on my cock. Filling all your tight little holes with cum. The way you'd look with my dick stretching out that pretty mouth..."

"God yes," she whimpers, beginning to slowly grind against you. Your cock is definitely getting hard again now, making her gasp as it swells inside her ass. "I used to imagine you just grabbing me one day and taking what you wanted. Pushing me up against a wall and shoving your big cock inside me..."

"Yeah? You wanted me to just use you like a little fucktoy?"

"Yes! Fuck yes," she confesses. "I wanted you to treat me like your personal cumslut. Make me take that fat cock however you wanted..."

Your dick is fully hard again now, throbbing inside her cum-filled ass. You can feel your previous load still leaking out around your shaft as she continues grinding against you.

"Well now we can make up for lost time," you tell Seulgi as you pull out of her slowly, laying on your back on the bed as you pull her on top of you. "I'm going to fuck this tight little ass whenever I want now. Fill you up with load after load of cum..."

"Promise?" she asks breathlessly, grabbing your cock in her hand as she slowly reinserts it into her ass, sitting on top of you. The new angle lets you fully appreciate her perfect petite body - those perky tits, flat stomach, and that incredible ass currently impaled on your shaft.

"Fuck yes I promise. But now I want to see your perfect little body riding my cock..." You grab her hips and thrust up into her, making her cry out in pleasure.

"Oh god! Yes! Let me ride you," Seulgi purrs. She starts rolling her hips experimentally, getting used to the feeling of controlling the penetration. Your previous load of cum makes obscene wet sounds as she moves, some of it leaking out around your cock and dripping onto your balls. The sight of your thick shaft disappearing into her tight little hole is fucking mesmerizing.

"Fuck, you look so hot like this," you groan, gripping her slim hips. Her ass clenches around you at the compliment, making you both moan.

"Yeah? You like watching me bounce on your big cock?" she asks breathlessly, starting to lift herself up and down properly now. The way she moves is absolutely perfect - she clearly knows exactly what she wants and how to get it.

"God yes, love watching this tight little ass take my cock," you tell her, giving her ass cheeks a squeeze. "Such a perfect little slut, riding me like you were made for it..."

Seulgi throws her head back and really starts going for it, bouncing enthusiastically on your dick. Her small tits bounce with the movement and you reach up to pinch her hard nipples, making her cry out in pleasure. The wet sounds of your cum squelching around your shaft get even louder as she picks up speed.

"Fuck! Your cock feels so good in my ass," she pants, grinding down hard against you. "Love feeling it stretch me open... Love having your cum inside me..."

You thrust up to meet her movements, driving your cock deeper into her tight hole. The way she's riding you is absolutely incredible - her ass is still gripping your shaft like a vice even after taking your first load. Every time she drops down, taking you balls deep, she lets out these perfect little whimpers that drive you crazy.

"That's it baby, ride that cock," you encourage her, running your hands up her sides to cup her tits. "Show me how badly you've wanted this..."

"Wanted it so bad," she moans, bouncing faster. "Dreamed about riding your big cock like this... Feeling you stretch my tight little ass..."

Her dirty talk spurs you on and you start thrusting up harder, making her cry out with each deep stroke. The sight of your shaft disappearing into her perfect ass over and over, still slick with your previous load, is absolutely incredible. Some of your cum is leaking out around your cock, running down onto your balls in thick white streams.

"Such a perfect little anal slut," you growl, squeezing her tits roughly. "Taking my cock so well, begging for more... Were you always this much of a cumslut or is it just for me?"

"Just for you," she gasps, grinding down hard. "Never wanted anyone else like this... Never begged for anyone else's cum..."

Her words make your cock throb inside her and you start really pounding up into her tight hole. The way she's moving her hips is absolutely perfect, grinding down to take you as deep as possible before lifting up until just the tip remains inside her. Her ass clenches around you each time she rises up, like she doesn't want to let your cock go.

"Fuck yes, ride that dick," you encourage her, gripping her hips tightly. "Show me how badly you want another load in this tight little ass..."

"Want it so bad," she moans, bouncing frantically now. "Want you to fill me up again... Want even more of your hot cum deep inside me..."

The sight of her riding you like this is absolutely incredible. Her perfect little body bouncing on your cock, her tight ass gripping and milking your shaft, the way your previous load is leaking out around your cock - it's all driving you crazy with lust.

"Gonna fill this tight hole up again," you grunt, squeezing her ass roughly. "Paint your insides white with another huge load..."

"Yes! Please cum in my ass again," she begs, grinding down hard. "Want to feel you pump me full... Want your hot cum deep inside me..."

You can feel your orgasm building as she continues riding you frantically, her tight hole milking your cock perfectly.

"Fuck, I'm close," you warn her, gripping her hips tightly. "Gonna fill this perfect little ass up again..."

"Do it! Cum inside me," she moans, grinding down hard. "Fill me up, mark me as yours..."

A few more bounces and you're there, groaning loudly as you start pumping another huge load deep in her ass. Seulgi cries out and clenches around you, her own orgasm hitting as she feels your hot cum flooding her insides.

"Oh god, yes! I can feel it," she gasps, grinding against you as you continue spurting inside her. "So much cum... Filling me up so good..."

You thrust up a few more times, making sure to deposit every drop of cum as deep as possible in her tight hole. When you're finally spent, she collapses forward onto your chest, her sweat-slick skin sliding against yours, both of you breathing heavily as your softening cock remains buried in her thoroughly fucked and cum-filled ass.

"That was fucking incredible," you pant, running your hands up and down her back.

"Mmm it really was," she agrees, nuzzling against your neck. "Best night ever. We definitely need to do this again. Like, a lot."

"Oh we will," you assure her with a grin. "I meant what I said - I'm going to use this perfect little ass whenever I want now. You’re mine. Officially. No take-backs.”

Her grin softens into something more genuine, and she cups your face, her thumb brushing over your cheek. “So we’re doing this? Like, actually doing this?”

“Hell yes, we are,” you reply without hesitation. “We’ve wasted enough time pretending we didn’t want this. And now that I know how good we are together, you really think I’m letting you go?”

She pulls you into a kiss, slow and deep. “Good. Because I don’t want to go anywhere. I'm stuck with you now.”

“Stuck with me?” you repeat, smirking. “Babe, I'm the one who'll have to deal with your insane ass from now on. If anyone’s ‘stuck,’ it’s me.”

“Oh, please,” she fires back, rolling her eyes. “You love my insane ass.”

“Damn right, I do,” you say, sliding a hand down to squeeze it for emphasis. “And I plan on showing you just how much, every chance I get.”

She laughs, wrapping her arms around your neck. “God, we’re so screwed up. Who the hell starts a relationship like this?”

You shrug, leaning down to kiss her again. “Us, apparently. And honestly? I wouldn’t have it any other way.”

The two of you stay tangled up in each other, talking and teasing until the conversation drifts back to the years of near-misses and unspoken feelings. It’s all out in the open now, and for the first time, it feels like everything’s exactly where it’s supposed to be.

—

You slowly open your eyes, still groggy from last night's intense activities. The morning sunlight filters through the curtains of Seulgi's bedroom, casting a warm glow across the messy sheets. Your naked body feels pleasantly sore as memories from yesterday flood back - how your petite best friend discovered those edited porn videos you made of her, and instead of getting pissed off, she got turned on. Who would've thought sweet little Seulgi was such a dirty girl?

The bed beside you is empty but still warm. You stretch lazily, enjoying the lingering scent of sex in the air mixed with her perfume. Your morning wood is already throbbing as you replay highlights from last night - Seulgi's tight little ass bouncing on your cock, her moans when you ate her holes, the way she begged for more...

The bedroom door opens and there she is - your best friend in all her sweaty glory. She's wearing a sports bra that shows off her perky tits and skin-tight leggings that hug every curve. Her skin glistens with perspiration, loose strands of hair sticking to her flushed face. Your cock instantly gets even harder.

"Good morning, sleepyhead!" Seulgi chirps, grabbing a towel to wipe her face. "Hope you don't mind, I always do my morning workout. Gotta keep this body tight, you know?" She strikes a playful pose.

"Fuck, you look incredible all sweaty like that," you growl, drinking in her athletic form. The way those leggings cling to her ass should be illegal. "Your body is fucking perfect."

She bites her lip, clearly pleased by the compliment. "Mmm, someone slept well I see," she says, eyeing your obvious erection beneath the sheets. "Still naked under there?"

"Want to come find out for yourself?"

"Actually..." Seulgi's eyes gleam with mischief. "I could use some extra cardio. Work up even more of a sweat..."

You throw back the sheets, exposing your rock-hard cock. "Get that sexy ass over here then."

Seulgi saunters toward the bed, her hips swaying. The musky scent of her post-workout sweat hits your nostrils and makes your mouth water. When she gets close enough, you grab her wrist and pull her down on top of you.

"Mmm, someone's eager," she giggles, grinding against your erection through her leggings.

You bury your face in her neck, inhaling deeply. The salty tang of her sweat mixed with her natural scent is intoxicating. Your tongue darts out to taste her glistening skin, trailing up to her ear.

"Fuck, you taste so good all sweaty," you growl. "I want to lick every inch of you."

Seulgi moans as you suck and nibble at her neck, leaving marks. Your hands roam over her toned body, squeezing her ass through those sinfully tight leggings. You've fantasized about her in workout clothes so many times, and now you finally get to live it out.

Your mouths crash together in a heated kiss. She tastes like mint - must have brushed her teeth before working out. Your tongues battle for dominance as you grind against each other. One hand slides up under her sports bra to pinch a hard nipple.

"These fucking leggings," you groan between kisses. "Do you know how many times I've jerked off thinking about ripping them open and fucking you in them?"

"Show me," she purrs. "Make those dirty fantasies real."

You don't need to be told twice. Gripping the fabric between her legs, you tear a hole right over her pussy and ass. The sound of ripping material fills the room as Seulgi gasps.

"Fuck yes, ruin them," she moans. "I love how fucking nasty you are."

You run your fingers over her exposed holes. Her pussy is already dripping wet, her asshole still slightly gaped from last night's pounding.

"I gotta admit, I'm gonna miss these leggings," Seulgi whines, but her pussy visibly clenches at the dominant display.

"I'll buy you new ones," you reply, tearing the hole wider until it extends from her lower back to her upper thighs. The torn edges frame her holes perfectly. "Now get to work on my cock while I eat this pretty pussy.”

She straddles your face in reverse, giving you a perfect view of her holes as she wraps her lips around your throbbing shaft. You groan at the wet heat enveloping your cock, the vibrations making her moan around you.

You spread her ass cheeks wide, admiring how her holes glisten with arousal. Her pussy is swollen and pink, cream already gathering at her entrance. Her tight asshole clenches invitingly.

"Such a pretty view," you murmur before diving in, dragging your tongue from her clit all the way up to her asshole. She shudders and moans around your cock, taking you deeper.

You alternate between broad licks through her folds and targeted flicks against her clit, gathering her tangy juices on your tongue. Her thighs start trembling as you suck her sensitive nub, her own oral efforts becoming sloppier as pleasure overtakes her.

"Mmmph!" she gags slightly as you thrust up into her throat, your hands gripping her ass to hold her in place. Tears gather in her eyes but she doesn't pull away, relaxing her throat to take you deeper.

You release her clit with a wet pop. "Good girl, taking my cock so deep while I eat this pussy." You punctuate your words by spearing your tongue into her dripping hole, tasting her deepest parts.

Her hips start grinding against your face as you tongue-fuck her, smearing her juices all over your chin. The torn leggings frame the erotic sight perfectly, the ripped edges emphasizing how thoroughly you're debauching her.

You pull back slightly to admire your work - her pussy is even more swollen now, her inner lips puffy and glistening. Her clit stands out prominently, begging for more attention. Above, her asshole clenches rhythmically, practically begging to be played with.

You drag your tongue up to circle her puckered entrance. Seulgi's whole body jerks at the contact, a muffled moan vibrating around your cock.

"Your ass is perfect," you murmur against her skin before diving back in, circling her rim with firm pressure. Her resistance melts away as you continue the rimming, replaced by breathy moans and hip rolls against your face.

You alternate between her holes - tongue-fucking her pussy until she's dripping, then moving up to tease her ass until it's quivering. Her own oral efforts match your intensity, her throat muscles massaging your cock as she deep throats you.

"Such a dirty girl," you growl between licks. "Getting your ass eaten while deepthroating cock... I bet you were planning this when you invited me to watch a fucking horror movie yesterday.”

She pulls off your cock with a gasp. "And it worked so we- Oh fuck, don't stop... feels so good..." She immediately swallows you back down, sucking with renewed vigor.

You focus your attention on her asshole, pointing your tongue to breach the tight ring of muscle. She practically squeals around your cock as you tongue-fuck her ass, her thighs shaking uncontrollably.

Her pussy is dripping steadily now, cream coating your chin and neck. You reach up to gather some on your fingers, using it to lubricate her asshole as you continue eating it. One finger slides in easily alongside your tongue, making her whole body jerk.

"Gonna make you cum just from eating your ass," you promise, working a second finger into her tight hole while your tongue continues circling the rim. Your other hand moves to her clit, rubbing quick circles on the swollen nub.

She's barely sucking your cock anymore, just holding it in her mouth as she pants and moans. Her hips rock desperately between your fingers and tongue, chasing her release.

"That's it baby, ride my face," you encourage, curling your fingers inside her ass while flicking her clit rapidly. "Want to feel you cum all over my chin..."

Her inner muscles start fluttering around your fingers as her orgasm approaches. You double down on your efforts, tongue and fingers working in harmony to push her over the edge.

She pulls off your cock with a cry as she starts cumming, her whole body convulsing. "Oh fuck, oh fuck, oh fuuuuck!" Her pussy gushes, coating your chin and neck with cream as her ass clenches rhythmically around your fingers.

You work her through it until she's whimpering from oversensitivity, then slowly withdraw your fingers. Her holes clench around empty air, still quivering from the intense orgasm.

"I-I n-need your cock in my pussy," she pants. "You didn't even fuck it last night because you were so focused on my ass. Time to make up for that."

You give her holes one last long lick before letting her climb off your face. Seulgi turns around and straddles your hips, rubbing her dripping pussy along your shaft.

"Watch how easily your big cock stretches my little hole," she purrs, positioning you at her entrance.

You groan as she sinks down, taking you balls deep in one smooth motion. Her pussy grips you like a vice, so hot and wet around your throbbing member.

"Fuck, you're so tight," you growl, gripping her hips. "Ride that cock, baby. Show me how bad you want it."

Seulgi starts bouncing on your shaft, her perky tits bouncing in the sports bra. Sweat drips down her toned stomach as she works herself on your cock. You reach up to pinch her nipples through the fabric, making her clench around you.

"Your pussy feels amazing," you moan. "So fucking wet for me."

She speeds up her movements, slamming down to take you as deep as possible. Her pussy makes obscene squelching sounds as your cock pistons in and out of her soaking hole.

You thrust up to meet her bounces, making her cry out each time you bottom out. Her pussy cream coats your shaft and balls, making everything deliciously slick. You can feel her inner walls fluttering as she gets close to cumming again.

"Play with your clit," you command. "I want to feel you cum all over my cock."

Seulgi reaches down to rub her swollen nub while continuing to ride you. Her movements become more erratic as pleasure builds. You grab her ass cheeks, spreading them wide and teasing her rim with your thumb.

"Fuck! I'm gonna cum on your cock!" she screams. Her pussy clamps down on your shaft as her orgasm hits. You keep thrusting through her climax, prolonging the waves of pleasure.

When her spasms subside, you pull out of her drenched hole. Your cock is coated in her cream, making it perfect for what comes next.

"Get on your hands and knees," you growl. "Time to stuff that tight little ass again."

Seulgi quickly assumes the position, arching her back to present her ass, the torn leggings frame her still-twitching holes perfectly. Her pussy is still pulsing from her orgasm, cream dripping down her thighs. Her asshole winks invitingly, already loosened from your fingers and last night's fucking.

You kneel behind her and rub your slick cock between her cheeks, teasing both holes. "You want my cock in your ass, don't you? Such a dirty girl, getting off on having both holes used."

"Please," she moans, pushing back against you. "Fuck my ass! I need it so bad!"

You press your cockhead against her tight rim, watching it slowly stretch around you. Despite being fucked there just hours ago, she's still deliciously tight. You grab her hips and steadily push forward until you're balls deep in her ass.

"Fuck yes," Seulgi pants. "Your cock feels so good stretching my ass!"

You start with slow, deep strokes, watching your shaft disappear into her hungry hole. Her ass grips you perfectly, sending waves of pleasure up your spine. You reach around to rub her clit, making her moan louder.

"Such a good little anal slut," you growl, speeding up your thrusts. "Taking my cock so deep in your ass while I play with your pussy."

Seulgi pushes back to meet each thrust, clearly loving the double stimulation. Her pussy drips steadily as you pound her ass, adding to the lewd sounds filling the room. You give her ass a hard smack, watching it jiggle.

"Harder!" she begs. "Wreck my fucking ass!"

You grab her hips tight and really start hammering into her. Your balls slap against her pussy with each thrust as you drill her asshole. Sweat drips down your chest, mixing with hers where your bodies meet.

The sight of your cock stretching her tight rim combined with her wanton moans has you getting close. You increase the pressure on her clit, wanting her to cum again before you finish.

"Gonna cum again," Seulgi gasps. "Keep fucking my ass just like that!"

Her whole body shakes as another orgasm rips through her. You feel her asshole spasm around your cock as she screams in pleasure.

“Fuck, I'm almost there,” you moan. “This time I'm gonna cover your little body with my cum.”

You pump into her stretched asshole a few more times, savoring the tight grip before withdrawing with a wet pop. Her gaping hole clenches around empty air as she quickly flips onto her back, her abs glistening with fresh workout sweat. The torn leggings frame her lower half perfectly, her pussy still dripping from her previous orgasms.

"Fuck, look at you," you growl, furiously stroking your cock as you kneel between her spread legs. Your shaft is slick with her ass juices, making obscene squelching sounds as you jerk it. "So fucking hot all sweaty and messy for me..."

Seulgi runs her hands over her damp skin, pinching her hard nipples through her sports bra. "Come on baby, mark me up. Want to feel your hot load all over my abs..."

Your cock throbs harder at her words. She looks like a fucking goddess lying there, skin golden and gleaming with perspiration, hair messy from getting railed, lips swollen from sucking your cock. The contrast of her still being partially clothed in her workout gear while being completely debauched is driving you wild.

"Play with yourself," you command, stroking faster. "Want to watch you rub that clit while I cover you in cum..."

She immediately slides a hand between her legs, fingers circling her swollen clit. Her other hand pushes her sports bra up to fully expose her perky tits, rolling a nipple between her fingers.

"Please," she whimpers, hips bucking as she pleasures herself. "Need your cum so bad... want you to paint me with it..."

You can feel your orgasm building, pressure mounting in your balls. Your cock is angry red and leaking precum steadily. Seulgi notices and licks her lips.

"Are you gonna cum for me baby?" she purrs, spreading her legs wider. "Want to feel it hot and thick all over my sweaty body... want you to mark your territory..."

"Fuck... gonna cum so hard for you..." you grunt, your hand a blur on your shaft. The wet sounds of her fingering herself mixed with your jerking is obscene.

"Do it," she demands, her fingers moving faster on her clit. "Fucking cover me... want to feel it splashing on my skin..."

Your orgasm hits like a freight train. The first rope of cum shoots out with incredible force, landing in a thick stripe from her collarbone down between her tits. The second and third spurts paint her ribs and abs, hot white streaks stark against her shiny skin.

"Yes! More!" she cries out, her own orgasm hitting as she watches you mark her. "Cover me!"

You continue cumming, decorating her sweaty stomach with rope after rope of thick seed. Some lands on the torn edges of her leggings, soaking into the fabric. The final few spurts dribble onto her lower abs, mixing with the sweat pooled in the grooves of her muscles.

When you're finally spent, you sit back to admire your work. Seulgi looks absolutely debauched - covered in sweat, cum, and pussy juice, workout clothes torn and disheveled, hair a mess. Your cum is already starting to run down the sides of her torso in rivulets, mixing with her sweat.

She runs her fingers through the mess on her stomach, spreading it around like lotion. The sight of her rubbing your seed into her sweaty skin makes your spent cock twitch weakly.

"Mmm, so much cum," she purrs, gathering some on her fingers and bringing them to her mouth. She maintains eye contact as she sucks them clean, moaning at the taste. "Love how it mixes with my sweat... makes me feel so dirty..."

She continues playing with the cum on her body, alternating between spreading it around and tasting it off her fingers. Some has dripped down to her pussy, mixing with her own juices.

"Fuck, that's hot," you groan, watching her enjoy your mess. She gathers more cum on her fingers and offers them to you. You eagerly suck them clean, tasting the salty mixture of your cum and her sweat.

"Love marking you up like this," you say as she continues rubbing the cooling cum into her skin. "Looking all sweaty and used, covered in my load..."

"Mmm, me too," she sighs contentedly. "Want you to do this every time I come back from working out... mark your territory all over my sweaty body..."

The combination of the visual, her dirty talk, and the various fluids coating her skin makes your cock start to harden again despite having just cum. Seulgi notices and laughs.

"Already getting hard again? Such a horny boy..." she teases, running a cum-covered finger down your shaft. "Save that energy for the next workout... want you nice and pent up so you can cover me in an even bigger load..."

You spend the next few minutes trading lazy kisses and caresses, enjoying the afterglow. Seulgi's skin is still flushed and glowing with sweat. Her sports bra is stained with your cum, marking her as yours.

"I should probably actually shower now," she says eventually. "Want to join me? I could use help getting clean... or maybe getting dirty again."

"Lead the way," you smirk, admiring her ass as she heads to the bathroom.

—

After the shower, you throw on some clothes and head to the kitchen. While Seulgi makes coffee, you raid her fridge for breakfast ingredients. The domestic scene feels surprisingly natural after the intensity of your sexual encounters.

"I still can't believe this all started because you caught me making porn edits of you," you say, cracking eggs into a pan.

She laughs. "I mean, I was shocked at first. But then I watched them and... fuck, they were hot. Made me realize how much I wanted you."

"Could have saved us both a lot of sexual frustration if we'd admitted it sooner."

"True. But making up for lost time has been pretty fun," she winks. "Plus now I have a personal trainer who really knows how to motivate me."

Breakfast becomes less about eating and more about stolen touches. Her fingers graze yours when you pass her a plate, and your knees bump under the table like it’s on purpose. Each bite of food comes with a side of heated glances that linger too long. The energy between you is still electric, even after having sex twice just this morning, alive with the kind of hunger that never truly fades.

Seulgi reaches across the table, her thumb brushing a crumb from your lip. Her touch lingers, her gaze heavy with desire. "We’re really bad at pretending this isn’t gonna happen again in about five minutes, huh?"

You grin, pushing your plate aside.

"Who’s pretending?”

This week’s writer spotlight feature is:  @cuips-not-cute! cuips_not_cute has six fics in the Stranger Things fandom on AO3 and all of them are in the Steddie tag!

Our anonymous nominator recommends the following works by @cuips-not-cute:

he could be brave

blood is an aphrodisiac

honeyed affection

blinking red light

cyclical

"cuips is a master of taking the reader on an emotional roller coaster ride. The amount of times I've laughed and cried at the same time reading his fics have been too numerous to count. Especially the depth of the sex scenes and the character beats and growth they portray are gorgeous to read - and also very titillating. I love Steve and Eddie in every one of cuips stories, adore the little mannerisms they are given and the way they interact with each other and other characters. Besides the inspiring prose cuips can pull off a plot like few other people I've found so far - since blinking red light is still ongoing, I'll just point to cyclical for that. I'm very thankful to cuips for writing and posting these stories and for being a very active part of this lovely fandom." -- anonymous

Below the cut, @cuips-not-cute answered some questions about their writing process and some of their recommended work!

Why do you write Steddie?

i don’t even know. i was happily in the ofmd fandom when i watched season 4 almost three years ago now (oh god) and then the characters… they got me. i fear they’ll never leave.

What’s your favorite trope to READ?

god, so many. they’re all kinda the same flavor though so i’ll list out what i’m always filtering for to find a new fic: bottom/sub eddie, creature/monster eddie, post s4, canon compliant, soft dom steve, sex pollen, spit kink, rimming (perhaps my FAVORITE ever thing to read), switch eddie/switch steve… the list goes on.

What’s your favorite trope to WRITE?

probably also rimming. there’s just something so romantic about eating ass. and i really love to stick with post s4 canon compliant aus, too, i don’t think i’ve written an actual for real au yet, though i do have an idea for one after brl.

What’s your favorite Steddie fic?

i don’t know if i can pick!! my ao3 bookmarks host my many all-time faves, but if you wanna go by the fic i’ve reread the most it’s probably the affliction of the feeling. it’s so fucking good.

Is there a trope you’re excited to explore in a future work but haven’t yet?

YES!!! i have never written omegaverse!!! which is crazy, ‘cause i like it a LOT. i have a post-s4 omegaverse au kicking around in my head currently, and i cannot wait to sink my teeth into all the messy biology and politics that come with the omegaverse.

What is your writing process like?

chaotic, in a word. usually, i’ll get a fic idea while i’m balls-deep in writing another fic so i’ll shove it to the side and let it simmer while i finish that first one, then i’ll spend a good long while planning it out in ridiculous detail, and THEN i’ll start actually drafting. i like to have a fully fleshed out outline and a couple chapters written and edited before i start posting, and once posting begins i tend to deviate quite a bit from my outline but it’s all good fun.

Do you have any writing quirks?

definitely. i don’t like pointing them out for fear of other folks seeing them in everything i do, but they’re there. one that i don’t mind so much is my absolute abuse of the word “little.” everything is “a little” of this, “a little” of that, but i try to cut my usage down significantly while i’m editing.

Do you prefer posting when you’ve finished writing or on a schedule?

i always TRY to keep a schedule but… yeah. it never works. i’m far too busy for one, but attempts are made. i’d like to one day write a fic in full before posting it, because i think it’d be a whole lot better if i let it sit for that long but lord, i sure do like getting ao3 comments on every chapter. they make the writing motivation go WAY up.

Which fic are you most proud of?

brl, definitely. that fucker is LONG and i’m barely halfway through it. i think i’ve done a lot of cool things with it and i’m going to do some more cool things and i’ve made a lot of really awesome friends in the process of writing it so it’s got some pretty insane sentimental value to me. it’s definitely going to be a fic i’ll miss writing once i finish it, but that’s what the epilogue series is for!!!

How did you get the idea for blinking red light?

from another fic!!! @racketghost is the author of one of my favorite things i’ve ever read, which is the good omens zach and miri au, closed set (https://archiveofourown.org/works/23320960/chapters/55862155 <- hyperlinked), wherein crowley has been lying about the existence of some angelic sex tapes to all of hell, and then he and aziraphale have to actually make the tapes. it’s awesome. it’s gorgeous. brl is one big giant love letter to this fic, because it means so fucking much to me and i think about it ALL the time. 

When writing honeyed affection, what was something you didn’t expect?

hmm, i don’t know? ha is, i think, a pretty easygoing fic with lots and lots of porn stuffed inside it, and that was all i intended it to be so i cannot think of anything i was surprised by!!

What inspired blood is an aphrodisiac?

i just wanted to write vampire eddie. it was july ‘22, kas theories were everywhere, i had to try it. these days i think i would change a LOT about it because my ideas and hcs surrounding the characters have evolved significantly, but i’ll write vampire eddie again and “fix” everything i no longer like about biaa.

What was your favorite part to write from he could be brave?

…the fisting. i genuinely think some of my best writing is in that scene, and while i feel the same way about this fic as i do biaa, the fisting scene will always hold a special place in my heart. i’m very, very excited to write the fisting chapter in brl because of this scene. fisting rules.

How do/did you feel writing cyclical?

i wrote cyclical during a very weird few months of my life, so writing it was sort of my way of dealing with all the insane shit going on around me, and i think it shows. in a good way, though, because cyclical is a timeloop fic so it needed to be a little angsty and insane. i’m stupidly proud of that fic. @ryeallytired actually BOUND it into a PHYSICAL BOOK and SENT IT TO ME and when i tell you that is the singular most precious object i own, i mean it.

What was the most difficult part of writing blinking red light?

PLOTTING THAT BITCH. GOD. i’m so happy to be actually WRITING it now, the planning was genuinely so brutal. my issue was that i was sticking too close to the plot of closed set (<3) which just… did not work for steddie. closed set’s premise centers around crowley lying about making sex tapes, yes, but he lied about them to PROTECT aziraphale, which is the messiest, kindest, riskiest fucking thing ever. and it’s awesome. in the early planning stages of brl, i was trying to put eddie in the crowley role of lying about having made sex tapes with steve, but it reallyyy didn’t work. there was an oc and i absolutely hated him, plus i didn’t like what that premise was doing to eddie’s character… ugh. it was a MESS. it took several rubber duck-ing conversations with my brilliant friend @lollaika and a rewatch of zach and miri to finally realize that it had to be STEVE who brings up the idea of sex tapes so that he could protect eddie, rather than eddie bringing it up to save his own hide (yikes).

Do you have a favorite scene and/or line from any of your fics?

oooh, lots. reallyyyy loved chapter 8 of cyclical with all of the pov shifts, that was super fun to write. i also really enjoyed writing the dry humping/sex tape convo in the first chapter of brl, and i’m stupidly excited to write chapters 12, 13, 15, and 17, because of specific scenes that will happen in each.

Do you have any upcoming projects or fics you’d like to share/promote?

i do!! after brl is completed i’ll have to choose from two story ideas (because i cannot have two wips at once or i’ll get SO stressed), one being a semi-realistic steddie cowboy au based off my own experiences with growing up on a farm and featuring messy, earnest cowboys and not-fully-human eddie, and the other being the omegaverse au i want to write, which will have a very fun mix of vampire eddie, dubcon bitching, and accidental mating bites!!!

Outside of these questions, Is there anything YOU would like to add?

i cannot think of anything!! this was super fun :D

Who TF decided that the His Dark Materials (Golden Compass) books were for kids/young adults?

I attempted to read them when I was the "target" age for them and it was the first time I ever remember tapping out on a book because it was above my reading comprehension (I regularly read books that were 2-3 years ahead of my "reading level" and was generally up for a challenge so that should tell you how much of I struggled). I gave up partway through the second book, The Subtle Knife, and didn't touch them again until this year.

And, boy, am I glad I waited! There is so much to this series that would have just been totally lost on me as a kid. The way it explores theology and morality would have gone right over my head. Even now with a bachelor's degree in English literature under my belt the depth to these books astounds me.

Every chapter of the Amber Spyglass opens with a quote from Milton's Paradise Lost, or one of William Blake's Songs of Innocence and Experience, or some other theologian or philosopher or outright Bible verses. Every chapter. In a series that was regularly promoted to 10 year olds. Yes, kids can be pretty smart and I hate when adult authors talk down to them, but what 10 year old is reading Paradise Lost?

I'm not saying you need a degree to understand this stuff, but you would have to have read a lot of foundational texts to get the full depths of the references. I also ended up leaning a lot on the religious study courses I've taken (and theological education from growing up Catholic) to identify specific religious theories/schools of thought which was just fascinating. Religious groups HATE these books! They're extremely critical of organized religion and Christian beliefs especially as they are canonized by the Catholic and Anglican churches. It's a three-book fiction trilogy exploring and arguing against Milton's interpretation of original sin.

So why was this series labelled as YA? Simple, the protagonists are kids; they're 12 years old.

Why did Pullman write about 12 year olds if the series wasn't meant for them? Because the biggest theme of the story is sin and children are considered innocent. Lyra and Will are coming of age and transitioning from childhood innocence to adulthood and its accompanying consciousness/self awareness that allows us to be held responsible for sinning.

Anyway here's an entry to the literal Wikipedia page for the series that I think sums it up:

Although His Dark Materials has been marketed as young adult fiction, and the central characters are children, Pullman wrote with no target audience in mind.
