    All Her Quirks (ft. LOONA's Hyunjin)

    SinsWithPleasure◈Apr 30, 2026

    “You can look, you know? I don’t care. I’m literally naked in front of you. This is every guy’s dream, roomie.” Or, the fic where Hyunjin is an... interesting... roommate.

    3

    Being Kim Hyunjin’s roommate is… interesting, to say the least. You’ve never met, let alone roomed, with someone with such a four-dimensional personality at any point in your life. However, here you are, three years into your college degree, sharing an apartment with this quirky yet beautiful woman.

    Of course, with her quirks, there comes troubles sometimes. You’ve had to apologize so many times when she randomly sang ‘Into The Unknown’ at the top of her lungs, or when she acted like a cat to get out of trouble with the landlord. She could be a deal of trouble sometimes, but… she wasn’t something you couldn’t deal with. In fact, you want nothing more than to have her around like that.

    Three years with her meant you had plenty of time to get to know her. You’d ended up knowing her pretty well—so much so that you’d ended up with feelings for her that you’ve harbored for quite a long time now. You still blush when you think about how much akin to a cat she is sometimes when she acts cute, or when she meows as a response. Hyunjin might as well be the human equivalent of a cat—even the way she wakes up is extremely cat-like, similar to how a kitten would rouse from sleep. There was no doubt about it—your roommate is the cutest girl ever.

    Another thing that kept you particularly attracted was how strong she was. You’d caught her multiple times doing squats hugging the giant bottles of water from the university campus water dispenser, and you know for a fact she can even carry some of her fellow teammates from the dance team easily. She’s even picked you up once, though not for long. She’s swept you off your feet, both figuratively and literally, and you’d have it no other way.

    You sigh as you walk down the hallway to Hyunjin’s room. Even after all this time, you’re still nervous when stepping into her room. It’s her space, and you can’t help but feel like you’re not supposed to step in. Even worse, you can’t keep your mind out of the gutter—who knows what private things she gets up to when she’s alone…?

    Faint music wafts from behind the closed door of Hyunjin’s room. You recognize the electronic synths of Panic!’s 'Casual Affair’ playing from the speakers.

    Knock knock.

    “Oi, Hyunjin-ah.”

    “Come in!”

    You open the door and feel a blast of cool air against your face.

    “What’s up, roomie?”

    As you state your intentions, you turn to shut the door behind you. The music stops behind you

    “Hyunjin-ah, I’m going to the mart. What do you wan—wait, huh?”

    When you turn back, you’re greeted with the sight of Hyunjin leaning forward, her elbows on her desk as she peers at the game she was playing. That’s not out of the ordinary—what is, however, would be the expanse of bare skin that you can see between the gaps of her silky hair that forms a curtain down her back, the smooth exposed meat of her thighs— Is that the curve of her breast—?!

    “What the fuck—Hyunjin!”

    “What?”

    The girl in question swirls around in her chair, and you’re greeted with an intimate view of just how hot Hyunjin’s naked body is. However, you’re quick to shield your eyes—you shouldn’t be looking at her without her consent, no matter how much it probably was an unspoken 'Yes’, considering the situation.

    “You—whyareyounaked?!”

    “Aeong!”

    “That’s not an answer, Hyunjin!”

    “It’s comfortable! Wearing clothes when I’m alone is annoying!”

    You hear her soft footsteps as she moves around. The telltale click of Hyunjin’s bottle and sound of water flowing plants the mental image of her drinking from her bottle the usual way she does like an athlete, pouring it straight into her mouth. However, you just can’t get over the fact that she’s literally naked right in front of you.

    “You can look, you know? I don’t care.”

    “What do you—No!”

    You shake your head vigorously even as you shield the sight of her from your eyes. As much as you want to, it’d be wrong—you’d be ogling her, and you respect her too much to subject her to your lustful gaze.

    “Why not? I’m literally naked in front of you. This is every guy’s dream, roomie.”

    You can’t believe what she’s saying. She has to be punking you. There’s no way any of this is real. Hyunjin has a weird sense of humor that you can’t fully understand sometimes, but this…

    In your confusion, arousal, and panic, you miss the footsteps that get louder towards you.

    “Quit being so gentlemanly, roomie.

    "I trust you.”

    Hyunjin’s hands wrap around your wrists, and she pulls them away from your face. You keep your eyes shut and head turned away when your hands fall, and you gulp as you feel the warmth of her hands on your cheeks, the scent of her orange body wash enveloping you. She turns your head to face her.

    “It’s okay, you can look.”

    The temptation is stronger than your discipline is.

    Your eyes open, and you’re greeted with Hyunjin’s bright smile, her cute canines on display. You let your eyes trail down her arms, and they fall on her bare shoulders, on her defined clavicles. You simultaneously want to, yet do not dare to look down—you’re definitely not going to look at her without lust…

    “Yah, am I pretty?”

    Hyunjin steps back and flashes a peace sign. She gives you a soft, relaxed grin, her slow nod signaling her consent for the third time. You finally let your eyes fall lower than her shoulders…

    Soft perky breasts greet your vision, her brown nipples taut with what was probably arousal, though you wouldn’t dare to assume. You shamefully let your eyes linger on her chest as you attempt to memorize every detail, from the soft curvature to the way they rise and fall as she breathes. Under the light of the LED bulb from her ceiling, you can see how perfect her tan skin is, how perfect her body is. Your eyes roam again, down to her soft tummy, the same one you always wish to wrap your arms around in a back hug. One more move down, and you finally get to feast your eyes on her sex. Hyunjin is shaved clean, and you can’t help but feel your arousal burn brighter as you note your accurate guess.

    You can’t believe how beautiful she actually is.

    “Y-Yeah…”

    Your gaze returns to her eyes, and her mischievous grin has you groaning inside.

    “You haven’t even seen all of me yet and you’re answering already?”

    Hyunjin turns around right after her question, and you finally get your first eyeful of her big, plump ass.

    Your cock twitches in your shorts at the sight of her butt. She’s always worn FBT shorts at home, or the occasional biker shorts, and those left nothing to the imagination already, showing off the full curve of her rear. However, those times would never beat this moment now, with Hyunjin actively showing you the best part of her body with a smirk across her face.

    “So, am I pretty?”

    “Yes.”

    The answer is almost instantaneous.

    “Mmhmm…”

    You see Hyunjin give you a once-over when she turns back around, and you finally notice the tent in your shorts. You don’t move to cover it—Hyunjin’s already seen it anyway, and with the way she grins back at you…

    “You know, roomie, when I said I trusted you, I meant it, right?”

    She steps closer, until you’re almost touching her.

    “I trust you, so…”

    Her hand wraps around your wrist and she leads you—

    “You can do anything you want to me, right now.”

    Your palm lands on Hyunjin’s hip. Her breath is hot against your lips, and her eyes flicker from them to your own.

    “So what’s it gonna be, roomie?”

    Your next decision is a no-brainer.

    Your lips crash into Hyunjin’s as both of your hands grab on to her plump asscheeks. Hyunjin’s arms wrap around you as both of you give in to your baser instincts. You grope her ass roughly, and Hyunjin clearly doesn’t mind—she moans so sultrily into your kiss with her. She mirrors your actions during the kiss—her hand firmly fondles your bulge. You break the kiss to gasp in pleasure when she slides her hand beneath your waistband to grab your cock. Her hand slides along your length, and your groan in response has her cursing softly.

    “Fuck, I’ve wanted to do this for so long, roomie…

    "Do you know how many times I’ve masturbated thinking of you touching me like that?”

    You whimper at the imagery of Hyunjin with her hand between her legs, her sweaty body writhing in pleasure as she moans your name. Hyunjin’s tongue slides along your neck, and her shaky breath brushes against your ear on a particularly hard squeeze of her ass, a soft moan escaping her throat at the end.

    “You know you can touch me anywhere, right?”

    Hyunjin leads one of your hands from her ass to her chest. She pushes your palm against her left breast, and she presses against your fingers. You take her prompt, and you fondle her chest softly, paying attention to rub your palm against her nipple.

    “God, fuck, that’s right, roomie, you’re making me so wet…”

    The girl in question dives for your earlobe, and with her lips on your flesh, her hands jerking along the length of your now exposed cock, you’re powerless under her touch.

    “Hyunjin—!”

    Hyunjin has you pinned against her door. When she finally lets your earlobe go from between her lips, she chases your lips for another kiss. Her soft lips crash against yours desperately, your tongues meeting in the middle as you share the dirty kiss with her, a lewd display of how much the both of you have wanted each other.

    “God, you’re so fucking hot…

    “You’ve seen me, but—mmf!—I haven’t seen you. Take these clothes off, roomie.”

    You’re quick to pull off your own shirt—you nearly tear it off with how desperate you are. Hyunjin is already pushing your shorts down, and you step out of them after you throw your shirt aside. Hyunjin pins you against the door once more as she lunges for your lips, and now you get to intimately feel just how soft her body is and how warm her skin is, with her body pressed against yours. You wrap your arms around her and run them up and down her back, enjoying the experience of having your dreams fulfilled—Hyunjin is right there in your arms, naked, your lips locked in an erotic display of lust, tongues swirling around each other, her hands kneading your ass the same way you kneaded hers.

    Hyunjin pulls you towards her during the kiss, and both of you stagger around her room clumsily. You bump into her bed frame, and she bumps into her gaming chair, which she kicks aside. However, none of that matters—what does is the girl you’re kissing, and how you’re about to finally fuck her. She maneuvers you until the backs of your knees hit the bed frame, and she breaks the kiss for air.

    “Careful.”

    “Wha—?!”

    With that one word as warning, she showcases her strength next—she picks you up and throws you onto her bed, and she crawls over to straddle you, her knees on either side of your hips.. Her eyes display the sheer want she has for you, and she bends over, her ass up in the air, her face hovering over yours.

    “Hyun—”

    “Shh.” Her left index finger rises to halt your words, before it is replaced by her lips again in another openmouthed kiss. Your cock twitches at the image of Hyunjin crawling and straddling you, and the tip catches her right on her clit. Both of you twitch and moan into each other’s mouths, and she breaks the kiss to grab your cock and press it down against your tummy. You watch in pure arousal as she positions herself right above it, her palm gently rubbing against your frenulum.

    “Hyunjin…”

    “Look at how wet I am, roomie…

    “It’s all your fault.”

    Hyunjin smirks as you stare at her pussy. You twitch against her hand again as you enjoy the sight of her puffy labia, spread open to reveal her dripping pussy and her clit poking out of its hood. As if by magic, her juices drip down onto your cock at that moment, and you whimper at the thought and feeling of having Hyunjin’s pussy on your wet cock in some manner. You’re twitching against her hand again, and the girl on top of you can only giggle at how needy you are.

    “You’ve got to fix this…”

    Hyunjin sinks herself down towards your length, and she moans out loud when she finally comes into contact with you. Her labia wraps around the underside of your cock, and she begins to grind her hips down along your length, mutually masturbating both you and herself with her simple actions. Both of you can’t hold your pleasured moans, her airy breaths against your low groans, and neither can the both of you resist looking at each other’s show of pleasure. It is only natural for both of you to chase for each other’s lips, to enhance the experience with each other through another kiss. Hyunjin holds your head steady with her hands, while you support yourself on one elbow, the other hand on her nape.

    When the kiss breaks, Hyunjin speaks, her words mingling with your moans.

    “I’ve wanted this for so long…

    “You look so hot like that, roomie.”

    Her fingers push on your chest, and you follow the force back down to Hyunjin’s soft mattress. Her scent envelops you when she leans over you, and both of you admire each other as she keeps grinding down on you. The sensational warmth of her lips so close to yours feels so good, your moans mixing with hers, and you can’t help but raise your hands to hold her hips as you grind against her as well. Hyunjin’s broken moan has your cock twitching again, her eyes squeezing shut tightly as her hips buck once. Fuck, you’re just as wet as she is—not only is your cock glistening with her juices, you’re staining your own tummy with white precum.

    “Hyunjin, you’re so fucking hot, fuck…”

    “And you… you’re so—ah!—fucking handsome, roomie.”

    Hyunjin reconnects your lips to hers in a deep kiss. This time, she keeps it short, and when she breaks the kiss, she lifts herself off your cock.

    “No, Hyunjin—!”

    You whine in protest as a response—she had a rhythm going, and you were enjoying yourself so much. Hyunjin holds her finger to your lips to shush you again.

    “Shh, shh, shh… don’t you want my pussy, roomie?”

    That shuts you up real quick.

    “That’s what I thought.”

    Hyunjin giggles as she grabs your shaft and lines it up with her cunt, her knees on either side of your tummy. You groan as she slides your tip along her slit, and the tingles of pleasure sent across your body from the contact with her, paired with the vision of Hyunjin’s pussy covering the entirety of your cock, has you attempting to push yourself into her out of the desire for more pleasure as well as to watch her take your cock fully. Thankfully, Hyunjin isn’t in the mood to hold herself back either—she stares right at you as she sinks herself down on your cock. Both of you let out loud, pleasured moans as inch after inch of your cock is engulfed by Hyunjin’s tight, warm pussy, your hard shaft stretching her walls. You can’t believe how warm she feels, how fucking tight the squeeze is on your shaft.

    “Fuck, Hyunjin, fuck, fuck, fuck!”

    “Oh my God, you—you’re so fucking big!”

    Hyunjin places her hands on your chest to steady herself. You’re only halfway in, and with one hard push, Hyunjin takes you all the way to the hilt. Both of you gasp at the feeling—Hyunjin feels so full, and you can’t believe how fucking good her pussy feels around your cock, as if it was made for you. Hyunjin falls forward, her hands moving right above your shoulders to support herself. You bite your bottom lip at the sight of Hyunjin’s chest jiggling as she pants, and you let your eyes rake lustfully over her body while you attempt to burn this sight into your memory forever.

    “Oi, roomie…

    “Congratulations, you’re mine now.”

    There’s no time to reply or even ponder about her words—Hyunjin begins to lift herself off your shaft. When half of your shaft slips out of her sex, she slams herself back down with a loud moan, which draws one of your own too. With this much pleasure coursing through your veins, you might as well be in heaven already. Hyunjin fucks herself on your shaft over and over, and you fuck back into her on every downstroke of hers. The pace she sets at first is slow, as if to try you out, but she gets faster as time goes by, with more of your cock sliding out, and the strength of her fucking herself back increasing as well.

    “God, fuck, roomie, it’s so good, sex with you feels so good!”

    “Hyunjin, oh my God, fuck, you feel so good like that too, shit!”

    You grip hard on Hyunjin’s hips to keep her steady with every thrust of your cock into her cunt. Her eyes are half-closed as she enjoys herself, her hands balled into fists as she bounces her hips up and down on your length. The pace she sets increases again, her pussy wetter, tighter, hotter…

    “Oh my God, I’m gonna cum, roomie, I’m gonna cum so soon, fuck I’m so close, oh God, I’m gonna cum, fuck, fuck, fuck, I’m gonna cum I’m gonna cum I’m gonna fucking cum—!”

    With a loud cry of pleasure, Hyunjin falls apart right in your arms. Her hips buck uncontrollably as she falls forward, your cock springing out of her tight cunt. What surprises you is the gush of fluids that drench your legs and cock as Hyunjin squirts all over you, her orgasmic moans right next to your ear. Loud hisses and splashes of her juices stain her sheets and spray messily all over your skin with every shudder of her body, her hand shoved between her legs to rub her own clit for more pleasure. It takes a while for her orgasm to die down, and when it does, she whispers the hottest words you’ve ever heard from her.

    “Roomie, I squirted…”

    “FUCK!”

    In a fit of arousal and overflowing lust, you flip Hyunjin over on her back to lie on a dry spot. You silence her yelp of surprise with a harsh kiss before you spread her legs open. With one thrust, you hilt deep into Hyunjin, and in an instant, you’re pistoning into her still sensitive cunt. The girl beneath you cries out in pleasure as you fuck her hard and fast before you muffle her vocalizations with hot openmouthed kisses, which reduce her cries to whiny moans. It doesn’t take long for you to get close—you’d been plenty close already earlier, and with Hyunjin’s squirting orgasm burnt into the forefront of your mind, it definitely made your fuse even shorter.

    “I’m gonna fucking cum in you, Hyunjin!”

    “Please, please roomie, please cum in me, please!”

    Hyunjin’s begging is the final straw as you explode deep into her with an almost animalistic growl. Her legs wrap tightly around your hips, her ankles wrapped in a tight lock around you as she prevents you from pulling out of her. Every blast of your cum is punctuated with a hard thrust, each violent expulsion of your thick, hot semen fucked deep into your roommate’s used pussy. You paint Hyunjin’s tight cunt white with over ten shots of cum, your balls thoroughly emptied into her in one orgasm.

    You don’t pull out of Hyunjin even after your orgasm subsides. Both of you collapse to the side in a tight cuddle, and you cradle a sweaty Hyunjin against you.

    “Hyunjin, are you okay?”

    “Yeah, but I’m so full, roomie… you came so much…”

    “That’s because you’re so fucking hot—” You bite back your words too late, and a huge blush explodes across your face. You… you’ve just had the hottest sex with Hyunjin—

    Hyunjin looks up at you when your retort is cut short, and she begins to laugh at your panic. She kisses you right on the tip of your nose, and squishes your cheeks in her palm to bring your attention to her.

    “You’re mine now,” she echoes.

    “Wait, what do you—”

    “You’re mine now! We’re dating!”

    “Huh?”

    “Don’t play dumb with me, roomie. I know how much you’ve wanted me for the past year~. You’re not that subtle!”

    Hyunjin strokes your hair gently and arranges your messy locks.

    “And now you’re mine, in my bed, after the best sex of my life.”

    Her ending words make your cock pulse.

    “We’re dating now, roomie! Consider this my official confession—I love you too!”

    Now, a mischievous grin…

    “Aeong!”
