Y/N house isn't far from the boys dorm. It takes Cory and Jeonguk about 10 minutes to walk until they're standing in front of her apartment complex.
'Are you ready?' Cory asks and Jeonguk tries to hide a smirk. 'More than ready, hyung'
Cory squints his eyes at his younger friend but doesn't say anything.
'I'll ring the bell and we go upstairs. You hide outside the apartment and I will open the door for you when shes occupied making hot cocoa. Where will you hide, once inside her apartment?' he asks. Jeonguk rolls his eyes. 'Her bathroom. I got the plan, hyung, let's just go'
Cory sighs. 'I hope this isn't a mistake' he thinks to himself.
Upon hearing the doorbell ring, Y/N hurries excitedly to the door to open up for her boyfriend. She's excited for today, it's her birthday and Cory promised her a present she won't easily forget. Whatever that meant, she was excited to find out.
She hears a knock on her front door and opens up quickly, smiling from ear to ear.
'Hey Cory!!' she says happily. 'Hello Babe!' he says just as excited. He takes her waist into his hands and lifts her up shortly. 'Happy Birthday!'
She giggles and he lets her go, kissing her briefly before swinging an arm around her shoulders and walking inside, closing the door.
Jeonguk watched it all, a little back in the hallway and his excitement was bubbling up inside of him again. Y/N is very pretty. He always denied it, I mean she's dating his best friend, that's wrong right?
When Cory asked him to do this for her, he was in the second he mentioned 'threesome'. He had a thing for Y/N, too, he just pushed the thought of having her the way he wanted for the sake of his friendship to Cory away. If they only knew, how often Jeonguk had to excuse himself because Y/N walked around in their dorm in only Cory's oversized sweater and panties. She was so comfortable with everyone in the group, it wasn't a rarety so see her in only her bra for a couple seconds. Jeonguk just seemed to have that incredible luck to get out of his room that morning the second she walked out of Cory's bedroom into the bathroom.
Sometimes he just straight on went back to bed because he certainly didn't want to explain to his members why he's holding pillows over his frontal area the whole time eating breakfast. Daeil and Changsun would just tease him and try to find out who he was dreaming about, when in reality the reason for his hard on was just one room away from his own.
Cory's harsh but quiet yell of his name rips him out of his thoughts and he walks towards Y/N apartment. 'Sorry' he mumbles when entering and Cory softly smacks his arm. 'Be quiet' he mouthes and holds a finger to his lips. Jeonguk nods.
He quietly gets out of his shoes and puts them away with his jacket, trying to take as less attention to him as possible.
'Babe? Where are you?' Y/N asks and is about to round the corner when Cory walks towards her, leading her back to the living room. Jeonguk lets out a breath he has been holding in. Jesus, that was close.
He hurriedly gets into the guest bathroom and waits for Cory to get him.
Playing games on his phone seems a little off when he knows what's going to happen in a little while, so he just shuts the phone off and leans back against the wall, thinking about Y/N again.
Just thinking about her butt in those panties makes him bite his bottom lip. He sighs deeply, already kind of regretting that he agreed to this in the first place. He worries, that if he actually gets to have a taste of the real feeling of Y/N, there's no going back. Imagining is one thing, but having her for real? That's another story.
Cory said, he'd blindfold her so she's not going to see anything at first. Then, it's Jeonguks turn to make her feel good. Kiss her neck, down to the valley of her boobs and paying special attention to her nipples in the progress. Wandering down her spine with his hands, until they're resting on that sinfully good looking ass of hers. He secretly hopes, she's wearing those panties he saw that one day. His mouth giving her tummy wet kisses, trailing down to her core. Her whispers for Cory to hurry up, which he imagines are being very hot when in reality he's the one who makes her shiver. He's going to cup her core and feel the wetness, and he's going to have to bite on his tongue to not moan out loud.
'Fuck..' he whispers to himself and places his hand on his growing member. 'Stop this, Jeonguk, now's not the time to get a boner. Cory hyung is going to be pissed if he saw' he thinks and forces himself to stop thinking about what's happening in her room the next few hours. Without success, though.
He's relieved when Cory finally opens the door to get Jeonguk. He's admitting to himself, that his stomach makes twists and twirls, but he's never going to speak it out loud.
'Come on, she's ready' Cory says and Jeonguk opens his mouth. 'Okay'
Walking into her bedroom as quietly as possible, Jeonguk has to stop himself from groaning when he's seeing Y/N standing in the middle of the room, in only her underwear and a blindfold. Like the gods above have heard his prayers, she's wearing those black silky panties she wore that one day. He bites his lip, and looks at Cory.
'Babe? Cory, love, where are you.. I feel awkward waiting like this' she speaks and Jeonguk lets his lip go and waits for Cory's instructions. He nods his head at Jeonguk and mentions for him to go ahead.
Cory positions himself right next to Jeonguk and speaks. 'I'm here, baby. Not going anywhere, you don't have to feel awkward at all. You're in good company' he says and smirks at Jeonguk, who grins back. Slowly, Jeonguk starts moving his hands towards her waist. She hisses when his cold fingers touch her warm skin.
She starts to lift her arm to touch him, but Cory speaks up before she can. 'Nah-ah. Forgot what we agreed on?' he asks and she lets out a breath. 'No touching until you allow me..' she whispers. Jeonguk has to mentally slap himself to stay quiet. She's so incredibly sexy like that.
'Exactly. One more time, and I'll get the handcuffs' Jeonguks eyes are about to pop out of his eyes when he hears Cory.
She starts smiling a little. 'And what if I want to be handcuffed?' she teases. Jeonguk can't believe what just got out of her mouth. She wants to be handcuffed? Holy Shit.
'Baby, you are not in control tonight. So behave' Cory says and Y/N just nods with a simple smile. 'Okay, Daddy'
At the nickname, Jeonguks mouth automatically opens and he lets out a breath. He regrets it the second later, because of course she noticed. 'Do I make you nervous, baby?' she asks. Cory motions for Jeonguk to continue to touch her and he does what he's told to. She immediately shuts up and starts to softly moan, when Jeonguks hands roam around to her back and unclasp her bra. It instantly falls to the ground and his hands are on her naked boobs now, kneading and pinching her nipples softly.
The soft moans she's giving Jeonguk are enough to drive him wild and he leans in towards her exposed neck, nibbling on the skin.
Cory watches from next to them, and he's very satisfied with the situation. She seems to be enjoying this very much, but so does Jeonguk. When Y/N adressed Cory with her nickname, he intently watched Jeonguk and saw what an impact that name had on him. He smirks to himself before speaking, 'What do you want Daddy do to? Use your mouth, baby girl and tell me what you want me to do'.
Jeonguk stares at her appearance, opened mouth, her flushed cheeks and the first drop of sweat making its way down her neck.
'I want you to play with my boobs. To circle my nipples and I want you to cup my core and rub my clit to make me feel good' she says. Jeonguk is about to explode. He's so hard already, it hurts to be in his skinny jeans. And hearing her dirty talk like this, he's about to lose his cool.
After Y/N's commands, Jeonguk happily complies and gives her boobs the much needed attention. Her moans are getting heavier the more he sucks on her nipples. Jeonguks hand leaves a tingling trail on her skin as he wanders down to her core. Cupping her through her underwear, she suddenly grips his hair. Jeonguk stops what he's doing and just stares at her.
'Baby girl, what did I say about touching me?' Cory said and motions for Jeonguk to leave her body. 'Im gonna have to cuff you up now, baby' he continues and walks towards the night stand.
'But Cory... please... I just want to touch you.. It's my birthday!'
Cory comes back and stands right in front of her. He leans into her ear and licks the shell. 'I know, babe, and you have absolutely no idea what you're going to get for your birthday, is that right?' he asks and she mumbles a yes.
'I'm bringing you to the bed now, stay still' Cory says and with a swift motion he lifts her up and brings her over to the bed.
'Can I take off the blindfold, Daddy?' Y/N asks, but Cory ain't having it. 'No.' he says sternly and cuffs her to the bedpost.
He leaves the bed after he cuffed her properly to the bed and nods Jeonguk back over.
'Why would you leave the bed? Cory, please I'm getting impatient' she whines.
The tone of her voice sends a shiver down Jeonguk's spine. He's absolutely captivated by her.
'Ah baby, no worries I'm already coming back' Cory says and pushes Jeonguk forward. He dips down onto the bed and licks his lips. Hell, yes. This is what he dreamed about, Y/N laying under his body, trapped by handcuffs, the bed and his posture.
His head slowly lovers to her boobs again, spending quite a lot of time with them before his tongue trails down her tummy towards her underwear. Jeonguk takes the underwear between his teeth, before he starts pulling it down her long legs. Her breathing gets uneven and her anticipation grows from second to second he takes to kiss up her thighs.
'Cory, i swear to god, please, please just eat me I can't handle this teasing anymore' she begs and that's enough for Jeonguk to dive straight into her core.
He closes his eyes, enjoying the warmth she's spreading through his system and the taste that consumes his mouth. Her moans are getting louder and Jeonguk hears that she's pulling at the cuffs, trying to reach his hair.
He decides to tease her core for a bit before he starts to pay attention to her clit. Rubbing her with his tongue, while one finger is resting against her entrance. 'Please, Daddy, oh god, please finger me, please' Y/N moans and Jeonguk groans against her clit, sending vibrations through her whole body, making her shiver. 'Oh my god...'
Jeonguk takes his time to tease her opening, wanting to hear her beg more whilst he's already working his magic on her clit. After some time, though, he decides that she's been teased enough and he plunges two fingers at once inside her opening.
Her intake of breath and the arching of her back make him stop immediately. He takes his free arm to push her down by the waist and continues to pleasure her in the best ways.
Cory, on the other side, sat on the couch at the other end of the room and watches his best friend destroying his girlfriend's core. His hand is steadily pumping his own member, trying to release some of the pressure. He can't believe himself, he is watching how his girlfriend is about to come by his best friends mouth and fingers. And the worst thing there is, he is actually enjoying this.
Y/N's moans are driving him insane, her pleas for Cory to go faster when it's Jeonguk pleasuring her. He can't wait until she finds out. Which will be sooner than he thought.
The reveal was supposed to be big. When she came, Cory wanted to say something from the other side of the room, making her instantly know that it definitely wasn't Cory who was pleasuring her. Jeonguk played his role perfectly, he didn't say a word the whole time, it is Cory who kind of messes everything up.
He lets out a hiss, when his hand was going over his tip, smearig the precum over his aching cock.
'What was that? Cory- oh god- what was the noise?' she asked, but Jeonguk is doing his work very well and she is close, so she just decides to ignore it and concentrate on the pleasure she is recieving. 'Fuck, fuck don't stop now, Cory holy shit, go faster please, please' she begs and Cory's mouth is open, so his breathing isnt all too loud. 'Cory, I'm close' she admits and that's Jeonguks cue to go faster and harder than he did before.
Her moaning increases, she's shaking when the wave of pleasure hits her. Y/N's eyes are blindfolded, but she still closes her eyes shut very tightly and leaves her mouth open, letting out all the sinful sounds that drive Jeonguk insane.
Jeonguk laps up all of her remaining juices before caressing her thighs. Now it's Cory's time to speak up.
'You did amazing, baby girl. I am so proud of you' he says from the couch and Y/N instantly freezes up.
'C-Cory?' she asks in terror. If Cory is at the other side of the room, who has been pleasuring her the past thirty minutes?
'Wh-Who-' she can't even finish her sentence because she is way too shocked. She's been pleasured by a stranger, she thought it was her boyfriend and moaned his name, but obviously it wasn't her Cory who made her feel good.
Jeonguk licks his lips before kissing up her tummy, going towards her neck. Goosebumbs are forming on her skin, when Jeonguk gives her nipples a short treatment each before going further up.
He kisses her neck, her jaw and the corner of her mouth before he connects his lips with hers.
Surprisingly, she instantly kisses back and tries to pull at the chains again. Jeonguks hand goes up to her hair and grabs it, feeling her locks between his fingers.
Y/N would not admit it in front of Cory, but whoever is kissing her right now had the ability to make her wet again, even though she just came down from her high.
Jeonguks other hand travels back down her body and to her bottom, squeezing it. That earns him access to her mouth and he instantly slips his tongue out to lick her lip and then start to battle with her tongue. All of Jeonguks fantasies just became true and he couldn't be any happier. He silently prays to god that Cory will let him fuck Y/N and have her his own way.
Y/N breaks away from the intense kiss to catch her breath and has her mouth hung open, lips red and swollen, her lipstick completely smeared.
Jeonguk licks his lip once more.
'Baby girl' Cory says from behind them. Y/N veins are pumping blood at an incredible pace and her breathing doesn't get back to normal at all, which makes her very angry. 'Cory' she whispers and continues to try and catch her breath.
Cory motions for Jeonguk to continue, to finally reveal who was the one that made her feel so incredibly good.
Jeonguk leans back into her ear and hums. 'Mhm, Kitten' he says lowly into her ear and her heartrate picks up. Is that..? No, it couldn't be. She was now just imagining things, why would Jeonguk be in her bedroom with Cory? It doesn't add up, he always said she's just a sister to him.
'Do you really not know who I am?' he continues to lowly talk to her before slowly unfolding her blindfold. She shakes her head hastily to get the material of her eyes, but Jeonguk stays with his head burried in her neck, giving her wet and sloppy kisses.
It takes a few seconds for Y/N to realize what's going on. And another few seconds for her to recognize the black locks in the crook of her neck.
'J-Jeonguk?' she asks and Jeonguk takes this as his cue to lift his head and look into her eyes with a big smirk. 'Hi, Kitten' he says.
Y/N can't believe what she's seeing. Jeonguk looks so worn out, his lips are swollen and red, her lipstick everywhere on his face and his hair is a little messy. Probably from when she accidentally grabbed his locks earlier.
After the realization hits her, she's speechless. She looks over to Cory, sitting at the other end of the bed.
'I-I don't understand-' she tries but Cory interrupts her with a chuckle. 'Calm down, baby girl. Remember when you told me you had a thing for Jeonguk?' he asks and slowly creeps further up her body. Jeonguk still lays half atop her, face back in her neck, peppering kisses all over her soft skin. His fingers dance at her opening, teasing her.
Y/N just weakily nods. 'Yes..' she answers softly. 'Well, I added one and one and thought about giving you what you craved. Jeonguk here hasn't had anything against it' he explains further and when Jeonguk hears his name, he bites into Y/N's skin softly and groans into her ear. Y/N's breathing gets uneven.
'So for your birthday present, princess, you will get pleasured by Jeonguk tonight. I may or may not lay a finger on you, too' Cory says and rests now at the other side of Y/N's body. 'I hope you enjoy your birthday present' Cory says and Jeonguk takes that as his cue to start pleasuring her again with entering her heat quickly.
Cory softly bites Y/N's earlobe and kisses her neck, sucking at the skin and marking her his.
The overstimulation is almost too much for Y/N to bare, but Cory's soft kisses and mumbles in her ear are making everything just more pleasurable.
She always secretly dreamt about this. She never told Cory, but she never really stopped having that little crush on Jeonguk. Of course, Y/N loves Cory with all her heart. He's such a goofball but in moments like right now he's just so hot. Theres both sides to him, and she loves it.
Y/N is very good friends with Jeonguk, too. And she hasn't thought about him in a sexual way for a long time, but when they've gone to the beach the other day with the other guys and Jeonguk came out of the other car in just his bathing bottoms, she freaked out for a second and couldn't look him in the eye for the rest of the day. Having him on top of her now, fingering her into absolute bliss is everything she never thought she wanted.
Y/N's eyes are closed, but when she feels both men moving, she opens them to see whats going on. 'Relax, baby girl' Cory whispers into her ear and moves behind her, making her lay on his chest, caressing her hair.
Meanwhile, Jeonguk moves on top of Y/N and rubs himself against her heat. She moans out loud, surprising everyone in the bedroom equally. 'I'm getting impatient, please, please hurry Jeonguk' she whines and both men are staring at her. It's the first time she really spoke up after the reveal, and she's obviously very needy.
Jeonguk hurries to get out of his skinny jeans and boxers before putting on a condom and getting back on top of her.
Cory is whispering sweet nothings into Y/N's ear whilst Jeonguk is lining himself up with her entrance. He's getting nervous now, this is the time he's waited for the past year.
Pushing in slowly, he groans out immediately. 'Fuck...'
Her intake of breath makes Cory groan, as her head presses down onto his ever growing erection.
'Fuck, she's so tight' Jeonguk groans and slowly starts thrusting into her. Y/N is moaning uncontrollably, grabbing his biceps and watching his face contort in pleasure. She pulls his face down, kissing him passionately, moaning into his mouth whilst he's rolling his hips into hers.
Cory's heavy breathing in her ear drives Y/N insane. She lets go of Jeonguks face and searches for Cory's behind her back.
Cory gets the hint, moving his face to kiss her deeply. He slides his tongue across her bottom lip, making her open instantly.
Making out with Cory the same time Jeonguk is penetrating her makes the feeling just the more intense to Y/N.
When Cory then starts to intensly rub her clit, that's enough for Y/N to lose it all.
'Fuck, I'm so close oh my god' she whispers and cries out once Jeonguk reaches her gspot.
Cory rubs her clit harder, making her high built up at immense speed.
'Fuck, Y/N, I'm close' Jeonguk moans and Y/N nods. 'Fuck, yes yes yes, fuck I'm coming' she moans and Jeonguk takes this as his cue to thrust into her faster.
Not many seconds later, Y/N hits her high and moans out Jeonguks name, which causes Jeonguk to reach his own high, too.
Cory is watching the scenery and he's so happy that Y/N is actually enjoying this. He's admitting, he is a little jealous that she's enjoying this too much. But it's her birthday, and this is a one time thing.
After coming down from his high, Jeonguk walks over to the bin and throws the tied condom into it. Then, he collects his clothes and looks over at Y/N and Cory cuddling on the bed, and he has to smile.
Jeonguk wants to meet someone one day, too, that makes him feel the way Y/N makes Cory feel.
Slowly and quietly he walks out of the room to get dressed and leave the house.
