masterlist

ryujin panted, fanning herself after going through the same choreo for a few hours. she wiped off the beads of sweat on her forehead, quickly glancing at you. god, she was exhausted. exhausted, irritated and anticipating.

the choreographer clapped hands, thanking members and finally letting them go for today, all 7 of them bow down before grabbing their stuff and quickly walking out of the stuffy and warm practice room.

once at their dorms, ryujin threw her bag, not caring where it lands, as she plopped on bed, palming her cock through sweats. she sighed, not wanting to get off to porn, as it all now seemed the same and repetitive. unless…

you heard the knock to your dorm room, followed by it creaking open once you allowed someone to walk in. “hey,” ryujin says, closing the door behind herself, “i need your help. nothing too serious or hard, promise,” she says, locking the door behind her back while she speaks. you look up, “oh. okay, what is it?” you ask, a bit wary, as ryujin rarely asks for help from members.

“it’s just a simple favor, that’s all,” she replied, walking to where you sat and joining you. she placed her hand on your thigh, her action being followed by trail of goosebumps on your skin. “it’s just, you know… i’m kinda pent up. long rehearsals hours taking its toll. and i was thinking… why not to… relax? could be useful for both of us.” the implication behind ryujin’s words hung heavy in the air, as she waited for your response, knowing you couldn’t deny her.

you could only nod, feeling your face flush. ryujin smiled at you, tugging you close to her by your waist as she laid down on the pillows, already working on pulling down her sweats along with boxers. her half-hard cock sprung free from confines of underwear, “okay, you’ll need to do as i say,” she instructs, her hand slides down to rest on your hips. ryujin’s finger hook into the waistband of your shorts, pulling them down as well, “lay on top of me… yeah. just stay like that and don’t move, okay? take a nap, if you wanna.” she continued, and you nodded, feeling her hand wrap around her erection, giving it a few strokes before aligning it with your pussy. “i wanna try cockwarming. ever heard of that?” you gasp and shake your head in response. ryujin groaned as she felt your slick heat sliding along her aching cock, gathering moisture before looking back at you, “you’ll see.”

the moment she pushed you onto her cock, you gasped again, mouth falling open in silent moan as you sunk deeper and deeper on ryujin’s hard length. once she bottomed out, she let out a sight, mix of relief and pent up desire. “fuck… you feel incredible, darling. stay like that,” she whispered into your ear, making you shudder and nod. you found yourself relaxing, instinctively clenching around invading length. ryujin’s hand traced patterns on your cloth covered spine, making you feel relax more and more under her touch. occasionally, you’d buck your hips slightly, the movements followed by ryujin’s hand stopping and holding you in place. you wanted to say something but felt your eyelids grow heavier and heavier with each second…

you woke up to the sound of ryujin’s quickened breath, her hands on your waist, gripping soft skin tightly, “goodness… you’re so tight… i’m gonna…” her words dissolved into a whimper, as you felt her hips surge up. you gasped, feeling her cock pulse and throb inside your warmth and you felt hot spurts of her seed pump into you, making you nuzzle into the crook of ryujin’s neck.

she held you close, grinding her crotch against yours, as she emptied inside you, breath raged and face flushed. you soon followed after her, your own orgasm washing over you in waves, milking ryujin for all her worth.

after a while, you both lay panting, ryujin’s soft length still inside you, as you catch your breath. “that was… wow, it’s better than anything i’ve ever experienced.” ryujin brushed away strand of your hair behind your ear, “i hope you’d like to repeat.”

Can you write something about non/dub con with sub!Yuna and G!p dom!Ryujin? It can be anything

tws: stalking, somnophilia, panty sniffing, noncon

ok this sat in my inbox for a while because while i love this prompt and i love 2shin even more i just simply didn't have any dark thoughts ~

i woke up this morning thinking lots of dark thoughts, specifically about yuna because she's so free use coded :( (and dumbification coded but that doesn't really fit into the prompt) there's a reason why she's my icon.

Can you write something about g!p Dom!Ryujin and Sub!Yuna & Chae?

pairing: ryujin x chaeryeong x yuna

summary: …ryujin breathed out, looking at two girls in front of her. “what are you waiting for, isn’t that what you’ve wanted for a long time?” yuna said, while holding chaeryeong in her arms.

this has to be the worst day ryujin ever had in her entire life. she messed up every part she could, almost broke her leg twice and almost fell down the stairs.

frustrated, ryujin sat down on couch, closing her eyes and taking deep breaths. she expected anything to happen since this day is already shitty but she definitely didn’t expected someone’s hands on her shoulders, carefully rubbing them.

opening her eyes, ryujin looks up, now seeing her maknae, “are you tired, unnie?” yuna asked, in almost honeyed voice and made ryujin wary. “i— well, yeah. yeah i am.” ryujin confessed, not seeing the point of lying.

“can you stand up for a second and close your eyes?” yuna asked in her innocent manner and receiving a quick nod from older shin. not really wanting to stand up, ryujin still does that and closes her eyes.

it takes her a few seconds with her eyes closed before yuna announced, “okay, you can open your eyes unnie.” yuna said, clearly excited about something.

“what are you… doing,” ryujin breathed out, looking now at two girls in front of her. “what are you waiting for, isn’t that what you’ve wanted for a long time?” yuna said, while playing with chaeryeong’s breasts and looking right in ryujin’s eyes.

yuna had older girl between her legs, while chaeryeong’s face was as red as a tomato. yet, ryujin could clearly see desire in her eyes, especially when yuna’s hand was already under her longsleeve.

younger shin mischievously smiled, witnessing how hard ryujin already was just looking at both of them. yuna slowly got up, carefully connecting her lips with ryujin’s and making chaeryeong stand up too.

when younger girl became more confident, the kiss got more sloppier, involving their tongues and yuna backs down, letting ryujin lead the kiss. she almost whines in yuna’s mouth when she felt chaeryeong’s hands pulling down her gray sweatpants along with her boxers down, letting her cock sprung up.

“we noticed long ago how you look at both of us, unnie.” chaeryeong said, kneeling down. “consider that as our gift for your birthday.” she said, before ryujin broke the kiss, letting out a low groan. chaeryeong wrapped her lips around ryujin’s cock head, humming around ryujin when she tug her hair to make chaeryeong take more of her length.

ryujin’s other hand slipped under yuna’s shirt and making younger girl whine as she played with her nipple. yuna used her hand to clamp in over chaeryeong’s neck, feeling ryujin down her throat as ryujin pumped harder and harder into chaeryeong’s mouth.

chaeryeong moaned and ryujin felt it through her entire body, triggering her orgasm, one final thrust in and she shoot hot ropes of cum down chaeryeong’s throat.

pulling out, ryujin quickly pulled up her sweatpants, leading younger girls to her room, roughly making yuna lay down on her bed. younger shin whined, watching her unnies quickly getting undressed and watching, how ryujin softly pressed her lips to chaeryeong’s and tugging her hair.

breaking the kiss, chaeryeong sat down beside yuna, when ryujin was already between yuna’s legs. “we will make sure that our princess will feel so good, right, angel?” chaeryeong smiled in response before she connected her lips with yuna’s and letting her hand play with younger girl’s nipple.

yuna whined, as ryujin slid her cockhead up and down yuna’s folds, gathering her wetness and covering her cock with it as she jerked it slowly. “you like the idea of being filled up with my cum, don’t you?” ryujin said and before yuna could say anything in response, ryujin got a loud moan from younger girl, as she aligned her cock and pushed in, jolting her whole body forward.

chaeryeong kissed yuna again but now holding her hand on yuna’s neck, receiving small whimpers from girl under. ryujin’s hips already snapping against yuna’s at a brutal pace, “you’re taking me so well, princess,” older growls, pulling yuna’s nipples. each thrust sends pushes yuna forward as ryujin slams into her. “so damn tight-”

grip on yuna’s neck got tighter, before chaeryeong let yuna breath again, receiving praising from ryujin. chaeryeong bent over, now sucking yuna’s nipples and making yuna’s moans become hoarse. the red hand print on younger’s neck made chaeryeong start kissing yuna’s neck, while ryujin’s hand kneaded chaeryeong’s ass.

chaeryeong’s moans made yuna’s walls contract, squeezing ryujin’s cock and making her cock start to leak precum and making older shin let out a low groan. chaeryeong’s thumb started rubbing yuna’s clit, making younger girl cry out, while ryujin’s movements became more faster.

“please- please cum inside,” ryujin’s thrusting became rougher at yuna’s words and it took few more thrusts as yuna came over ryujin’s cock. ryujin’s came after her, shooting her seed into younger, hips jerking forward with each spurt that came out.

it took yuna some time to calm down from her climax, as she let out a whimper when ryujin pulled out due her sensitivity. ryujin pulled chaeryeong closer, now making her lay down, as her fingers teased chaeryeong’s entrance.

her fingers started to gather up the wetness that was coating chaeryeong’s pussy. suddenly, ryujin parted her legs and her already leaking cockhead was starting to tease chaeryeong’s folds.

pushing in and receiving a whine from chaeryeong, ryujin already had a brutal pace. “would you take my cum like a good girl you are?” ryujin whispered, while yuna’s hand played with chaeryeong’s breast. receiving quick nods from girl under her, ryujin rubbed her clit, making chaeryeong arch her back.

yuna put one hand and pushed it against chaeryeong’s lower stomach to feel ryujin in her and making older girl cry out, as ryujin could feel chaeryeong clenched down her cock.

“i- i’m gonna-“ chaeryeong whined, while yuna kissed her breasts. “do it. cum for me, angel.” ryujin said and she hadn’t tell her twice, chaeryeong moaned, as she came over ryujin’s cock. ryujin's movements became more and more erratic and her previous steady pace was turning into sloppy, weaker one as she cummed inside of chaeryeong.

“hold her, princess.” ryujin pulled out slowly, having yuna to pin chaeryeong down and receiving whines in response as ryujin watched the cum slowly leak out of her, using her fingers to keep it there.

ughhh that ryujin wanting yeji’s younger sister has me feeling a certain way, you’re such a good writer😣

can you do g!p ryujin fucking the reader in another room? while yeji’s still in the dorm?

Tysm bestie <3

Ryujin would be so shameless whenever Yeji was around the two of you. Yeji didn’t suspect anything was going on and just assumed her touchiness was a trait of your close friendship.

She would always be holding you in some way, whether It was a hand on your waist or on your thigh, keeping her smirk to herself and not drawing any attention to her actions as she chatted with the girls.

She got a lock installed on her bedroom door, telling the girls it was just for privacy sakes but really it was because they love the burst in unannounced and whenever your were around that was a recipe for disaster

Yeji was sat with Yuna in the living room, right outside the bedroom as they watched some film. Ryujin wasted no time with you, they were so busy recently that she just ripped your clothes off whenever she saw you.

Pressing you down gently on your stomach, the bed wasn’t the most sturdy thing in the world so she made sure that she was extra slow in her thrusts, the bed could squeak very loudly.

“Be quiet, okay?” She mumbled into your neck, placing a hand over your mouth to muffle your moans as she slid her cockhead through your folds. You were embarrassingly wet, in your defence the two of you hadn't had sex in over a month due to her schedule. She lined herself up and pushed into you, her hand pressing down harder as you let out a loud moan, she had to bite down on your neck to silence her own groans of pleasure. "Shhh," she slurred as she left sloppy kisses down your neck, she wasted no time as she began to pump in and out, struggling to stop moans slipping out at how your walls clenched around her cock. She really loved how loud you were, you were so sensitive to every little touch, and it pained her to silence you but the last thing she wanted was Yeji knocking on the door. But that's what happened. She was getting so close, she couldn't hold her orgasm off and neither could you, it just felt so good but Ryujin picked up on footsteps approaching the door, she tried but she couldn't help thrusting into you, but the door knocked. "Hey, guys? the food is on its way, be here in five minutes." Yeji called, and Ryujin froze for a split second before uncovering your mouth for you to answer. But she started fucking you again. "O-okay Yeji, be o-out in a minute!" you yelled out, Yeji seemed happy with your answers and you heard her footsteps get quieter, Ryujin started quickening her thrusts, hand over your mouth and her other on your ass spreading you. "Shit," Ryujin slurred out as you came around her, your orgasm triggering her own as she emptied into you. Huffing and falling down onto your chest as she finished.

Can u make smth where g!p ryujin and reader are close friends. One night reader goes to watch a movie at g!p ryujins place and it eventually turns up to reader sucking her big cock (+sex)?

synopsis: you come to celebrate your friendship anniversary with ryujin, only to end up starting a new chapter of your lives.

MINORS DNI ᝰ.ᐟ tags: gp!ryujin, unprotected sex, pet names, friends to lovers, oral sex, idk i love the idea of yearning and soft top ryu

Y/N and Ryujin knew each other since day one, and quickly became inseparable. Each small milestone? They experienced it together, always, hand in hand and with strong bond.

You always been there for each other, at your lowest and highest, no matter where and when. Even when you fought or argued, you couldn’t hold a grudge for long and were quick to make amends.

Recently, it was a 20-ish anniversary of your friendship, and today Ryujin called you over to do a small but nonetheless special celebration, which was your small tradition every year. You could use some time to unwind, especially after past few weeks. It’s been tiring and exhausting, but you could find some strength to get ready and go to Ryujin’s place.

Once inside and after sharing few hugs, you walk further, settling down onto the couch, "Want something particular? I got us uhhh… Your favorite snacks, no spicy. Also I grabbed some ramen, if you want." Ryujin says from kitchen, leaning on the kitchen counter. "I think I’ll stick to snacks for now," you reply, switching movie options. You hum, still not looking away from TV, "Maybe you can grab them and also go for wine? God, I want to relax a bit after those weeks." Sighing, you continue searching for a movie that could suit you both and would be at least interesting.

Ryujin chuckled at your words, and you heard her moving, getting glasses and wine. Once settled down too with snacks and chosen movie, you moved a bit closer to Ryu, to discuss some scenes or actions done by characters.

Occasionally, Ryujin would shift, sometimes several times at time. You didn’t mind it much, rather focusing your attention on the screen and speaking in low tone. As for Ryujin? This was a bittersweet torture. You were so close, yet so far. Despite being close for all those years, Ryujin kept a respectful distance and didn’t invade your boundaries. Ryujin wanted to lean in and nuzzle into your neck and keep her hand wandering on your thigh, but alas.

Ryujin shifted, trying to ease now persistent pressure in her jeans, adjusting the denim to ease the friction. She tried to keep up with plot and your occasional monologue, but all she could think of — you, and your mouth on her rapidly hardening cock.

You turned your head, noticing that Ryujin isn’t really paying attention to the movie, "Hey, Ryu, are you feeling okay? You seem waaay out of this place right now." You ask, placing a hand on her cheek, feeling the soft skin beneath. Before you could ask her further, Ryujin suddenly leaned in, pressing her lips against yours.

Once you reciprocated, humming into the kiss, you closed your eyes, your focus narrowing into this one perfect single moment. Ryujin would whisper filthy promises against your lips, slowly trailing her kisses lower and lower, before she gently but persistently tugged your hair, moving your head lower. Fumbling with her jeans, Ryujin with shaky hand unzipped the fly and pulled down her panties that were already soaked, freeing her aching member to your gaze.

You felt your cheeks burn at the sight, wondering if it would even fit, "Please, baby… I want to feel your mouth on me so bad…” Ryujin gives herself a few strokes, guiding her leaking tip closer to your parted lips. You take a tentative lick, before slowly engulfing at first tip and then first inches, working your mouth on Ryujin’s dick.

She let out a shaky moan, slightly bucking her hips to push a few more inches but not forcing you to anything. You bob your head, taking Ryujin’s hard flesh deeper, feeling her grip tighten in your hair, as she mewls something incoherent. Getting bolder, you take her deeper as much as you can, stimulating the flesh that didn’t fit by stroking it with your hand, "Oh- Oh, yes, just like that," Ryujin whimpers, and you can feel her cock twitch in your mouth, as her release is fast approaching.

But as just you were preparing to send her over the edge, Ryujin tugs on your hair and makes you release her cock from your mouth. On instant, she’s kissing you, her tongue dances with yours, as she backs you down, Ryujin’s hands roam over your body and under your clothes, pushing your shirt up. She quickly sheds your clothes, lowering her kisses, murmuring against your hot skin, "You’re so beautiful like that… I could get used to the sight of you like that." She breathes, before peeling your soaked panties off, and quickly joining you in the state of nakedness.

Ryujin kisses your temple, as she aligns herself with your entrance, "Tell me if it’s too much, okay?" She says, before slowly and carefully pushing forward, sinking inside you. You let out a high pitched moan, with each inch thrusted in you, your back arches from the soft couch more and more. Once fully inside, Ryujin turns your head to face her, and kisses you, at the same time starting to move her hips. You moan into the kiss, wrapping your arms around her, as Ryujin gradually increases the pace of her thrusts, "Ryu! Fuck, yes, don’t stop… Please don’t stop, you feel so good…" You whimper, feeling yourself getting closer and closer to the pinnacle of your high.

Sensing you clench around her cock, Ryujin’s one hand lowers to circle your clit, while other comes to knead your breast, "Fuck, yes baby, come for me… Please, let me feel you come undone beneath me for the first time."

Ryujin’s words is your undoing, and you cry out her name, as orgasm hits you hard and fast. You pant and whimper, feeling Ryujin’s thrusts falter, and after few more deep thrusts, she follows you in your shared orgasm with last hard thrust. She works you through your orgasm, her hips twitching as her high continues, until she lays down on top of you, sated.

Ryujin’s eyes are closed, but her hand caresses your hair, you both heavily breathe. "This is the best anniversary celebration and the best way to start celebrating another occasion in the future." Ryujin murmurs, looking up at you with loving eyes, and you can’t help but return the smile at her.

First of all welcome back,

Can you a friends to lovers with g!p ryujin, both are in the same pack kinda like Teen Wolf.

-🦋 anon

gp!ryujin x fem!reader

a/n: dare i say that i’ve never watched it 🫢

warnings: g!p, slight enemies to friends to lovers, lowkey made it switch!ryujin, unprotected sex

you turn around, hearing someone’s presence in the room. "oh, it’s you… you can at least announce yourself before entering, you know?" you say, as you look at ryujin’s smiley face. "what are you smiling at, ryuddaeng?" you ask, seeing older girl that shrugged. "nothing… do i need a reason to smile?"

you sigh, as you sat down bedside ryujin on the couch, examining her face. it’s actually hard to tell for you why you started liking her overnight and when that hate between you both ended. ryu looks like an epitome of your type but you don’t like her that way, do you? you’d rather have her as your…

"earth to y/n! are we here?" ryujin waves her hand in front of your face, trying to draw your attention to her. "sorry, just wondered about… stuff." you reply, turning away from her. "oh really? mind sharing your thoughts with me?" does she really need to be this… appealing? you pinched the bridge of your nose, sighing once again. "wanna make you sigh in a different way." you hear ryujin say, instantly turning your head to her direction. did you hear that right?

there was something about you that made ryujin irritated or was it just a reaction to your attitude towards her. you two weren’t on a good terms with each other but ryujin wouldn’t deny that you are exactly what she wanted in a girl. she secretly cheered when you started talking with her more and eventually became friends. of course, there still were some things that she hid from you, but maybe it’s you who’s a little ignorant about ryujin’s intentions or whatever.

ryujin’s hand playfully took your strand of hair, "do you really don’t get my intentions?" she asks, making you more confused than ever. now it’s ryujin’s turn to sigh, yet she’s patient, "i like you. not as a friend or coworker you know… we both work together but it would be hard to me to stay as friends." her hand was on your cheek, as she shyly turned her head away. is it real? or she just messing with you? you just open and close your mouth, unable to form any coherent sentences, as you feel ryujin grabbing your head and laying it on her chest. "ya hear that? that’s how fast you make my heart beat." ryujin’s voice softened as you look at her. "are you kidding me? i thought i was weird for feeling something… towards you." you almost whisper, now looking at ryujin differently. ryujin takes a deep breath before saying, "no, im not kidding you i just-"

the rest of the sentence ryujin hummed into the kiss, her hand grabbing your hair, moving you closer to her, if it’s even possible. older girl carefully lays down, you break the kiss to go down to her neck, holding back to leave any marks. ryujin’s breathing becomes more intense, she’s almost whimpering, "hold on… y/n, i-" ryujin tries to push you away but you resist. she sits down, holding onto her pants, hesitating to speak. she just takes your hand, moving it lower, until you sense her hard-on. older girl awaits for your negative reaction and she sighs in relief when you smile at her, "i’m totally okay with it, don’t worry about it. you’re as gorgeous as you always were." you sink yourself down, slowly rubbing the clothed cock.

ryujin whimpers, mumbling your name under her breath, as you unzip her pants, pulling them down along with boxers. you kiss ryujin again, pulling down your pants, slowly aligning her cock with your entrance as you adjust to her length. "oh my… god…" you moan out, ryujin’s hands placed on your waist, she slowly starts moving her hips, nearly ready to finish already. "ryujin… can you go faster, please?" you whisper, closing your eyes. it’s all too much for your liking.

who ryujin is to deny your plea? she starts pounding into you, making you moan even louder that she has to muffle you by kissing. your breathing becomes more intense, you getting closer to your release with each ryujin’s thrust. "oh- f-fuck, i’m gonna cum now!" ryujin moans out, her cock sips out of you before she shoots her load on her tummy, you both came at the same time.

you lay down, heavy breathing when ryujin’s hand caresses your hair. she placed a kiss on your forehead, holding you. "i love you."

"i love you too."

…ryujin’s whines muffled as you spoke, “so needy and desperate and that’s all for me only? look at you, poor baby…” you whispered in her ear, as your hand jerked her off but painfully slow. ryujin squirmed, wanting to break free from you but her hips bucking up every time your hand goes faster, makes it much more harder for her to think about anything actually. “nuh-uh, you’re not going anywhere. don’t you wanna me ride you?”

and there she is, ryujin’s hands are secure on your waist as tears cascade her face, her mumbling about how good you feel on her cock every time you slam down on her shaft. also her wiping away her tears, but every time she does that you slow down which makes her cry even harder 😭😭 poor baby is just so desperate to feel you and cum already for the nth time

right after her goodbyes to the crowd, ryu doesn’t really remember how she found herself sitting on the couch with her cock in your mouth, also hearing all your praises whispered in her ear? poor girl holds back not to cum right here and now, her hands in your hair, because she’s too shy and doesn’t know where to put her hands 😭
