MATURE UNDER CUT MDNI

Kim Hongjoong is everything Soobin wants to be. A strong leader. A respected producer. An ambassador. Someone to be looked up to and praised.

And you, Hongjoongs girlfriend of nearly three years, is all he wants. A loyal partner. An understanding person. A kind soul that clings to his.

He knows anything and everything there is to know about you and Hongjoong. He watches all of Hongjoongs content, he stalks you as you run errands. He knows the scent of perfume Hongjoong buys every other month and he has a caddy full of your favorite soaps. He knows how you only hold hands in the dark to avoid the paparazzi and he knows all of the sweet nicknames you call each other.

He knows how bad this could be for him should it ever get out that he's obsessed with his senior and his girlfriend. He knows first hand how badly it feels to be violated of your privacy. But he can't bring himself to stop. He can't help but bask in your existences. He needs to know more.

He needs to know the brand of condoms Hongjoong uses, if you take brith control. Does Hongjoong always take the lead like in those heated kisses he's caught glimpses of backstage, or do you like to have power in the bedroom? He needs to know if Hongjoong looks as beautiful covered in sweat in bed as he does on stage, he needs to know if your hair frames your face just as gracefully when your head is thrown back in pleasure.

    Just being a bystander isn't enough for Soobin anymore.

He needs to know what goes on behind closed doors.

彡★

The house is eerily desolate, perched atop a hill in the middle of a field. Nothing but trees and flowers and mother nature on her lonesome to witness what goes on in the lot. It was gothic in its architecture, pale in its color palette.

Despite the houses deathly aura, life rages in inside of it. Shadows of people dancing by the windows, muffled music leaking from the walls, a shout or yell every so often from a drunken party goer.

    You're clearly buzzed, Soobin can tell. You're stumbling around and gripping to the wall every so often as you move your body to the beat of the music. Hongjoong isn't around you, so he takes the opportunity to approach you. Though he gets nervous around you, his heart stops in his chest everytime his senior so much as addresses him directly.

"Binnie boy!" You cheer with a wide smile, discarding your red solo cup on the antique table behind you in favor of wrapping your arms around his slim torso. "I didn't think you made it!"

So you're an affectionate drunk. Lucky him-

His heart is beating wildly, he's never been more thankful for loud music. He can barely breathe, his arms tingling as he wraps them around your shoulders. God, you feel so warm. "H-hey, Noona. Are you enjoying yourself?"

"Oh, yeah! It's been forever since I went to a party," your hand lingers on his chest as you back away and grab your cup again, lighting his skin ablaze through the thin fabric of his costume.

After you take a swig, you offer it up to him. When he goes to shake his head, already blushing and feeling drunk on your proximity, you roll your eyes playfully and stand up on your tip toes, holding the lipstick-stained cup to his lip. "It's rude to refuse a drink," you tease, nearly cooing as he opens his lips and drinks immediately. "Good right? I think Gaeul made it."

He's not registering any of the words that are coming past your lips. His brain is going a million miles an hour as he feels the lipstick that's transferred to his lips. Sure, he has alot of the products you use but never from your own personal collection. Never from your own lips, even if it came off a secondary source. This is almost as good as when he found one of Hongjoongs sweaters at a thrift shop after watching him drop off a bag of donations.

"I found it!" Hongjoongs voice brings him back to his own body, and he's immediately frozen again as he feels the fur he knows he's wearing wrap around his shoulder. He has to be dreaming. Is he dreaming?

Hongjoong is right by his side, hip to hip with his arm stretched up and around his shoulders. "Is she teasin' you? She likes to tease when she's drunk," he chuckles, looking up and watching the younger mans face flush deeper as he stutters.

"I'm noooooot," you draw out dramatically, slipping your hand into his open fur coat and under his top. "I'm just being friendly- right, Binnie?"

He's nearly gasping for air as he watches the two of you. What in the world is going on?

"You found one?"

"Mhm," Hongjoong moves away from Soobin and drags you to the stair case, and he watches in confusion as you both stop on the second stair, your conversation hidden by the loud music and the shadows.

A few moments later, you're coming back to Soobin and grabbing his hand, "c'mon."

He can only follow the warm grip you have on his hand, blinded by how good it feels to have your skin touching his that he doesn't even notice as you lead him up the stairs to the bedrooms with Hongjoong hot on your tails.

"Wh-" The words die on his tongue as you let go of his hand and dive into the tall, elegant bed. "Non-" There they go again as he turns as sees Hongjoong latching the door locked.

You look like the angel you're dressed as as you lay down on your back, your head propped up by the pillows and your legs spread so invitingly.

"Isn't my Angel so gorgeous?" Hongjoong asks as he joins him at the foot of the bed, a smirk painting his face as he watches his ears flush pink. "Don't you just want to..." he trails off, watching in the corner of his vision as you pull the white dress above your hips teasingly slow, "fuck her dumb?"

"Hyung!"

Your giggles fill the room, and Hongjoongs follow, leaving Soobin stunned more than ever; a deer in the headlights. "Oh, c'mon Binnie," you moan as you slip your hand into your underwear, "we aren't blind."

"We see how you watch us," he finishes your thought, shrugging off his coat.

"Mhm," you nod in agreement, watching his bulge grow with his blush. "If you don't want to join us, close the door on your way out- ah!" Your laughter fills the room as Hongjoong jumps into the bed, kissing and licking at your neck.

His eyes flick between the two of you and the locked door. His mind is already made up but he doesn't want to seem too eager. He thought he was sneaky enough. How much do you both know?

"You're so wet just from teasing him," Hongjoong purrs as he slips his fingers into your bare heat, your skimpy panties discarded at the edge of the large bed.

He almost immediately starts pumping his fingers into your wetness, purposefully slapping his palm against your clit to create more lewd sounds. Soobins head is spinning. His eyesight is blurring, but at the same time he can see your face twisting in pleasure so clearly. He's crawling into the bed instinctively to get a closer look, his brain can't comprehend the amount of hormones that are flooding him. From your feet, he can see the wetness on Hongjoongs fingers as he pulls them out briefly before they dive back into you.

"Staying?" Hongjoong grins as he looks over his shoulder, slowing his fingers to give him a good showing of your wetness. He only nods in response, eyes never leaving your puffy clit and sopping hole.

"Ngh-" He moans as Hongjoongs free hand grips the back of his neck, forcing him face to face with your core. The sound of his fingers pressing against your walls paired with the scent of your arousal nearly makes him come undone the second the tip of his nose grazes your clit.

Your hand comes down and pets his head almost innocently, and he looks up your heaving torso to see you as you speak vulgarly, "have you ever eaten a pussy before, Binnie?"

       He shakes his head, the tip of his nose still forced against your clit by Hongjoongs grip.

      "She'll get you addicted," Hongjoong moans lowly at the thought of his own tongue on you, he can taste the memories, "she's fucking delicious."

He lays on his stomach between your legs, next to Hongjoong whos straddling your thigh. "H-how?" He forces his voice out, his hot breath fanning you.

"Show him how, Baby," you prop yourself up on your elbow and wiggle your hips, smirking at the two of them. "Show him how to eat pussy like a real man."

Hongjoongs slips his fingers out of you and sucks them clean as he positions himself next to Soobin, rubbing down his back sensually. "Watch close, even blink."

"Oka-" He's left speechless once again as his tongue darts out and laps up and down the length of your heat, pointing and circling your clit before diving into you and all over again. He listens to his Hyung, though he doesn't know if it's even intentional. He wouldn't blink if his eyes were dryer than the Sahara.

His skilled tongue skims and rubs and fucks all of the right places, not a single part of you left untouched as he moans into you. "Oh, fuck, Joongie," you squeal, thighs trembling briefly before they lift of the bed and press into them.

He pulls away and pushes the thigh that's pressing into him back down, nodding at Soobin to do the same. His slender fingers dig into your skin softly as he copies him, pressing your leg back into the soft sheets.

"No," you whine, "so close!"

"C'mon Princess don't be selfish, let our guest have a taste before you squirt all over us, hm?"

"Squirt- squirt? You squirt Noona?" He pants breathlessly. He doesn't know how he's going to survive.

You chuckle softly, head tossed back as you rub your wetness on his chin, getting oh so close to his lips. "Make me cum and you'll find out, Binnie. Go on, do what Joongie showed you."

He sticks his tongue out tentatively and flicks it across your clit. The high moan you let out. The taste of you. Hongjoongs burning gaze on him. It's so. Fucking. Good.

He copies all of Hongjoongs movements, it's not hard to. The image of his tongue working against your wet skin is burned into his memory and he will never let it go. He whines into your cunt, pressing his face closer as he savors your juices, his eyes fluttering shut as his hips grind against the bed on their own. His mind is gone from his body, his entire being washed in pure pleasure. He's so far gone that he doesn't register that your both turning on your sides, your legs sandwiching his face as you moan and groan.

      He feels Hongjoongs hands unbuttoning his pants, and he lets him. No way in any universe is he doing anything that will stop this moment. His length is engulfed in his warm hand, and the vibration of his moan is enough to send you over the edge, flooding his face and neck in your release and clenching your legs around his head tightly. The curses that fall off your trembling lips go unheard by the eager young man, who could nearly be drowning in the amount of fluids that you're washing him in, in the pleasure that Hongjoongs hand is giving him.

"Fuck, Binnie! Fuck, fuck, fuck! Son of a bitch- holy shit!" Hongjoong laughs, finally pulling his wet face away from you. His eye flutter open, his pupils blown way out of proportion. He pants, bucking his hips into Hongjoongs stilled hand.

"Ngh, Hyung," he whimpers, melting as he resumes stroking his length, "you were right, she's so delicious!" He licks his swollen lips, sliding onto his back and watching his slender hand pump up and down, blissfully unaware as you slip out from behind him and remove your clothes. "Oh my god," his eyes roll back into his head, and just before the pressure inside of him can snap, the warmth of his hand is gone. "No, no! Hyung!" His cock twitches in the air, hips bucking wildly.

"Shhhh," he shushes him softly, holding his hips down to the bed, kissing his jaw lightly, "don't you want to let it out inside your Noona? There's nothing else like it, Binnie."

You join them once again, on the opposite side of Hongjoong, naked body curled up to Soobins side. "All warm and wet, nice and inviting."

A whiny moan chokes him, jaw dropped as he nips his ear lobe, your fingertip swirling around his nipple. "F-fuck, please."

"Not yet," you whisper, "you'll cum the second you feel my hot pussy. Calm down a bit."

Both of your warmth is gone, and he opens his eyes. They widen at the scene infront of him.

Your naked body, all out in the open as your face is in Hongjoongs lap, ass in the air. His thick, veiny member resting on your flushed cheek as you fondle his balls.

"Is it everything you dreamed of, Soobin?" He grins as you take his cock down your throat, years of practice having paid of. "Isn't my girl the fucking best? Look at that," he coos as he points Soobins gaze to your throat, an the outline of him pressing out of your skin, "see how she takes it? Mmm fuck. If your lucky, maybe one day she can take that long, pretty cock of yours."

You moan around him, peering over at Soobin. He slides closer immediately and leans into your neck, taking in a deep breath of the smell of sex that comes from you. "Fuck," he groans, cock aching for attention. But Hongjoong is right, he wants to save it for you. He wants to know what Hongjoong gets to feel everytime you fuck. "Everything and more." He kisses your neck, and the feeling of his lips through your throat makes Hongjoong feral.

He grips the back of your head, thrusting deep into your throat with a short and fast pace. The sound of your throat contracting around his cock fills the room, even over the muffled music. Your spit flies out of your stretched lips, soaking his smooth pelvis. "Do that again," he growls quietly, free hand pressing Soobins face into your neck.

And he does, he licks and sucks at your neck, like he's trying to suck Hongjoongs cock just as much as you are. "Mhmp!" Your arousal drips down your legs, your hole clenches around nothingness as you steady yourself on his thighs.

The amount of attention you've been receiving tonight already has you back on the edge, teetering as your boyfriend chokes you on his cock and his handsome junior sucks hickeys in your skin. Your head is fuzzy with oxygen deprivation and arousal.

     You can feel his body tightening beneath you, and you get ready to swallow his release when he tugs your hair roughly. "Don't swallow, Angel," and with that, he pulls your mouth back to envelop just his tip and floods your mouth with his sweet seed, head tossed back and a bead of sweat dripping down his chin, chest heaving as he moans, "let him have a taste."

     He tenderly helps you up, positioning your face above his and smirking as he opens his mouth wide. The mix of saliva and cum leaks into his awaiting mouth, and a string of moans from all of you builds your arousal to an all time high. He gulps it down greedily and watches you intently as you move to straddle his hips.

You lick your lips clean, taking a peek at Hongjoong. He gives you a nod and grips the base of Soobins cock, holding it upright as you sink down on it. "Oh- oh shit," he bites his lip, eyes flicking from your blissful face to your sopping hole as you slowly descend to Hongjoongs member twitching back to life.

"Don't you dare cum, ladies first," Hongjoong fixes Soobins hair back and rubs his thumb on his lips.

"Al-alright- fuck! Oh fuck!" He whines loudly as you begin riding him mercilessly, clenching his gut as his brain begs for the flood of dopamine that it knows will come with filling your cunt in the most primal way. "Fuck, please! Noona! Noona!" He screams, hips bucking wildly and making his cock reach depths inside of you that haven't been touched by another person since you met Hongjoong. He doesn't stretch you as good as he does, but God does the slight pain as he rearranges your guts feel heavenly.

"How does it feel?" Hongjoong inquired, slipping his hand around your hips and circling his finger tips around your swollen clit.

"So good!"

"S'good!"

Both of you chime together, bodies bouncing on the soft mattress. "Oh, Joongie! You were right," you draw out in a moan, "he's so- ah! So big!"

"Ride him, Princess, ride that big cock," he smirks at him over your shoulder before diving in and sucking darker hickeys over the ones Soobin left. It's definitely a show of dominance, telling him not to get too comfortable in his girlfriends cunt. But he does. Not. Care.

He'll find an in eventually, for now he's content to hold onto your hips as you ride him like a mad woman.

"Noona," he whines highly, rutting into you desperately, "please let me!"

"Let you?" You question dizzily, rocking your hips into Hongjoongs fingers as they continue their assault on your clit.

"L- ah! Fuck, I'm sorry, Noona, I can't help myself anymore!" He thrashes, locking his arms around you and flipping you around. He cages you underneath him and slams back into you, banging his hips onto yours and burying his face in your chest as he clings to you.

Hongjoong crawls up to your face, cradling it gently as Soobins rough thrust toss you around. "You gonna let him cum in your pussy? That's my pussy, you know that?" He slaps your cheek softly, a large grin on his face. "Dirty Angel, you're enjoying having this freak in your cunt," he kisses you deeply and moans, pulling back and gripping Soobins hair roughly.

"Listen to me," he sneers, "you can fuck us silly all you like, you little horn-dog. But this is my girl. And I'm her man. Got that?"

      "Y-yes, Hyung!"

    "Good," he pushes his head away and goes back to you, fondling your breasts as he licks your ear, whispering something that Soobin can't hear over the pounding of his hips on yours, especially not combined with the music growing louder in his overstimulated mind.

Your moans are growing louder and louder, more frequent as he plunges into you rapidly. "O-oh shit..." You screw your eyes shut and bite your lip, and from his place looking down on you, Soobin wishes he had photographic memory. It's everything he ever made it up to be and more, and more, and more...

A broken moan rips out of your throat as you clench on him like a vice, squirting with each of his thrust as he ravages you. And that's all he needs to let loose, an orgasm like no other washing over him and soaking your insides, shutting his brain off as it floods with unimaginable pleasure.

He collapses into you, clinging to you for dear life as his hips continue driving into you with a mid of their own.

"Feels fucking amazing, huh?" Hongjoong chuckles, rubbing your heads simultaneously as he pries Soobin off of you. He straddles him carefully and slips his hands under his top. "Hope you've got some more energy for me, pretty boy."

彡★

       He stands as silent as a mouse and grabs his phone, eyes raking the two of you darkly as he searches for the perfect angle to capture you in your fullest beauty.

      Hongjoongs arm is draped over your naked chest like he subconsciously knows to protect your modesty from what's about to come, his ring catching the dim moonlight as he cups the side of your breast.

     He snaps a picture of your torsos and arms all mingled together, thankful that the lamp was left on so that he didn't have to risk the flash waking you. He knows you're a light sleeper.

    With a lick of his lips, he zooms in on his always noticeable bulge. It strains against his boxers even as he's flaccid and snuggles against your hip innocently.

He doesn't know when it got to this point. He doesn't care, frankly. He just wants in, he wants in- he wants in now. He wants to sleep in that cozy nest of a bed that he knows you make up every morning after cuddling your boyfriend all night. Seonghwa once told him about it and how you had to strip the bed of all your pillows and blankets and plushies so that Hongjoongs vlogs didn't share something that you felt so intimate about, he hasn't got to see it yet but he wants it so badly. He wants to spoil you with plushies to add. He wants to fuck you until you squirt on it all freshly made just to mark it with your scent and drive in the fact that he makes you cum like a lover.

     His soft panting fills the quiet air as he snaps a photo of the way your finger tips are pressed into the elastic band on Hongjoongs boxers.

He doesn't care that it's crazy. He just wants to be apart of you, and every little thing only adds to it.

     He leans one knee on the edge of the bed and snaps a close up of your bruised hips, the forming colors, to remind him of how well it felt to hold them as they boucned.

   He turns the focus to your face. You're the one he has the least photos of despite the fact that you're the one he's most obsessed in love with. You look so peaceful in your sleep, lips parted as you breath softly, a small smile twitching at the edges that he immediately snaps a photo of. You must be dreaming of him.

He. Doesn't. Care.

    He snaps photo after photo after photo after photo after photo of you. His girl. The lines on your soft, exposed stomach. Your fluffy sock clad feet. Your slightly swollen lips with his thumb carefully placed between them. The way you suck on it subconsciously. Your hair, the baby hairs that fall from the sloppy way you put it up. Every single freckle and mole and embellishment on your skin. Your thighs. Oh good God your thighs, he could die a happy man between them. The way goosebumps raise on your skin as he trails his fingers tips all over you. Your neck which still has his marks no matter how hard Hongjoong tried to cover them. Picture after picture after picture after picture until his camera betrays him and tells him he has only a little storage left to document your adorable, unconscious state.

Soobin

Does

Not

Care

     He backs up and gets every single piece of you both in frame for one last photo. Of the way the two of you meld together. His precious, stupid lovers.

     He will be apart of you. And this is only the beginning.

He got a glimpse of what goes on behind closed doors.

Now you'll never get rid of him.
