a/n: this specific nahyuck moment has caused severe damage to my mental health! :)
haechan was such a brat! and you and jaemin were seriously tired of his attitude today. you were haechans girlfriend of 3 years, and had grown extremely close to his best friend jaemin, and all day he had been updating you about your whiney boyfriend, text after text coming through like “he keeps whining about needing you” “he just tried to skip practice to go jerk off” “ya lil bf is complaining about your job saying you should be home waiting for him when he gets home every day so you can fuck him asap” “i’m seriously going to suck his dick atp just to get him to shut the fuck up” “yn, what are we gonna do with him? he keeps running his mouth” and you and jaemin were both progressively getting more and more irritated by his bratty behaviour and you’re not even there to witness it!
you text jaemin back while you walk to your car after leaving the office, “can you bring him home? i gotta teach him a lesson” “i wanna stay and watch, i wanna see that attitude slip, im sick of him, been touching his dick all day and walking around with a boner” you roll your eyes, just picturing haechan whining and grabbing at his junk around everyone, if he wants to flaunt it at work, you’re gonna give him a real audience tonight. you drive home, already seeing jaemins car parked next to your empty spot, parking and turning your car off you grab your bag and head inside and see them both on the couch. you look haechan up and down, sitting on the couch in just his boxers, man spreading on the couch as jaemin stands behind him, hand in his hair. you look to jaemin, grateful that he had already gotten haechan undressed and asserted some dominance already, speaking to jaemin and looking over your boyfriend who stares at you pathetically from the couch
“hey… thanks for bringing him”
“it’s alright, he’s been waiting for you, everytime he tried to touch himself i’ve been pulling his hair”
“good, he’s lucky if he gets touched at all after all his lip today, isn’t that right?”
you look back down to meet haechans gaze. he gulps, didn’t think jaemin would snitch on him for complaining all day, let alone get involved in your sex life so intimately. sure you have both spoken openly about it with him before, and you’ve sent jaemin pictures of haechan fucked out and subby as punishment, as a humiliation tactic, but he’s not gotten physically involved like this before.
“she asked you a question haechan, answer your girlfriend, stop being rude”
“y-yes… im sorry”
“yeah? you sorry baby bear?”
he nods his head as best he can with jaemins hands still in his hair. you sigh coming closer to him, kicking your shoes off on your way to him.
“what are you sorry for? do you know why you’re even apologising?”
“for… talking bad about your job… saying you should- should be waiting for me at home, being selfish- mmmm… f-for touching myself”
“good, you were being selfish, you know i love my job, you know it’s important to me, why would i give that up? just to pleasure you? i know you talking crazy, were you thinking with this?…”
you tap his head, right by his temple then cup his boner through his boxers, squeezing gently
“or this?”
“im sorry… i didn’t mean it, was just thinking with my dick…”
“yeah, time to stop thinking all together, you know you do stupid things when you think”
you motion for jaemin to move around the couch and take a seat next to him, leaving haechan in the middle of the pair of you
“now your dumb attitude got you in big trouble, gonna get punished not only by me, but jaeminie too, cause he’s the one who had to deal with you all day, jaem, take his underwear off”
haechan looks at you with wide eyes as jaemins hands start moving towards your boyfriends waist band
“don’t give me that look, you brought this on yourself”
jaemin starts tugging on his boxers, bringing them down his thighs and off his legs, leaving him fully exposed to both of you, his raging hard dick bouncing back and slapping against his stomach. pre cum leaking from his deep pink tip. your hand cups the underside of him and he shudders, jaemin watching his every reaction. your hand is slow and featherlight as it softly drags up and down his shaft, tracing his veins with your finger tip.
“keep him here, trap his legs, i’m gonna get a cock ring, don’t let him touch”
jaemin nods as he starts to shift closer to haechan. he starts to protest, pushing jaemin back but you grab his face and turn him to look at you as you stand up, talking through gritted teeth
“do what i say, don’t make me go harder on you, sit in his lap and be a good boy”
he can only whine as jaemin uses his strength to sit him in his lap, legs over haechans to stop him from wriggling too much, his big hands planted firmly around haechans petite waist to keep him grounded in his spot. you head upstairs and root through your toy drawer, bringing back a vibrating cock ring and a pair of cuffs. while your gone haechan starts to wriggle and writhe, feeling jaemins hard on as he sits in his lap.
“stop it, sit still”
“shu-shut up”
haechan can’t take it anymore, his face is flushed red with embarrassment and restraint and his hand starts to gravitate towards his manhood
“i would think twice about that if i was you”
he huffs and forces his hand back down by his side and jaemin hums in approval. neither of them thinking they would enjoy this as much as they are. when you get back downstairs you cuff haechan up first, securing each of the loops around his wrists before locking them behind his back, he tries to twist and pull them apart but jaemin just wraps a hand around his neck and pulls him back flush against his chest as you work on putting the cock ring on, once secured you stand up and look at both men; one naked, pathetic and embarrassed, skin glowing pink, the other calm, secure and fully dressed, much more in control. when you turn the vibe settings on haechan is immediately bucking his hips and letting out whiney moans and squeals and you sit back on your heels in between his legs and hold his legs open and keeping them under jaemins own legs.
“when are you going to learn to shut your mouth? you’re always running those gums, getting under our skin, whining and begging for attention, well you got it now, are you happy?”
he strains a groan and nods his head yes, jaemin swoops his hair back from his eyes, and soothes a hand up and down his torso, stopping at his peck, before rubbing and flicking at haechans sensitive nipple. you hum in approval when he starts to flinch and twitch, hips bucking and body twisting to try and get away from all the stimulation. you laugh softly as your hands grip his hips, mouth hanging wide open above his shaft, letting long hot globs of spit tumble down and coat him before your hand wraps around his shaft and starts to jerk him off. his moans get louder, jaemin holding him upright so he can’t escape. before he can cum you let go of him and he cries out desperately. you motion for jaemin to come and join you in front of him and he slides haechan back onto the couch cushion and joins you on the floor.
“do you want to touch him?”
“yeah…”
“alright, touch him, i’m gonna go grab something else, i’ll be back in a sec, do what you want with him”
haechan whines at how you speak to jaemin like he’s not even there, like he’s just a toy for you both to play with, and before you can evan fully make it to your feet again jaemins hands are fully wrapped around haechans shaft, ripping the cock ring off, before his hand is twisting and pulling, jerking him off. his hips buck into jaemins hand as he squeezes the sensitive tip.
“jaemin… ahh! nghhh…”
“pathetic little slut, look at you, bucking into your best friends hand, you dirty boy”
you come back holding a bottle of lube and your strap on harness with haechans favourite dildo attached. both jaemin and haechans eyes go dark. haechan cannot wait to feel you pound into him, and jaemin can’t wait to watch his best friend fall completely apart at the hands of his girlfriend, he might even step in and take part.
“nana will you help me put this on?”
you have a teasing smile on your face as jaemin stands, abandoning your poor boyfriend who still writhes on the couch, naked. jaemin ensures the harness is secure around your thighs and waist, making a show of gently rubbing over the insides of your thighs and groin to make sure each part of the harness laid flat. haechan huffs through his nose, jealous that jaemins hands were all over his girl, but the jealousy didn’t last long as he felt your hands pushing his legs up to his chest. jaemin walks behind him again, just like his you found them both when you first arrived home, he reaches out and takes hold of the poor boys legs, bringing them further back and in place for you. you squirt a generous amount of lube onto haechans hole, plus his shaft too, you want him as wet and slippery as you can make it. you lube up the silicone before your lining up with his entrance, you take your time, pushing the tip in little by little as haechan cries and whines with all his chest. his voice cracks and breaks as he begs for it, begs to be fucked, his throat strained from just how tight the stretch is. once your past the head, you push all the way down to the base of the toy so your hips are sitting as flush to him as possible, before pulling out completely to watch his hole contract, jaemin speaking up again
“fuck… ass took that dick like a champ baby, hole’s gaping nice and wide for us”
“he always takes it so good, always lets me stretch his little asshole wide open”
tears keep streaming down haechans face, his skin still flushed a deep pink, he usually loves when you fuck him, usually has no shame, but with his best friend right here, talking about his gaping asshole as a result of you fucking him open he has all of a sudden gotten stage fright. he feels you plunge back inside, revelling on the feeling of getting fucked, his favourite thing in the world other than you yourself, but before he can really start to enjoy it, the feeling of you slapping his dick snaps him out of his thoughts. his eyes and mouth snap open as he looks at you, his brows furrowed as you slap his dick as you fuck his ass. jaemin watches intently, listens to haechan crying and whining out loud as he can, his eyes trained on the way haechans legs shake in his hands, the look on his face, the way his head rolls back against the back of the couch and against jaemins stomach. jaemins smile is wicked as he leans down closer to haechans ear, keeping a firm grip on his legs to keep them spread
“taking it so good haechannie, you sound so much better like this instead of all that bitching”
“what do you say to jaemin?”
haechan goes to speak but he’s cut off by his own moans and squeals before you hold his shaft and squeeze tight
“i said, what do you say?”
“s-sorry! agh! i’m sorry!”
“good boy”
you jerk him off again but before he can cum your hands stop and draw back, pulling the strap out of him and jaemin drops his legs. he sobs out hard, lunging forward off the couch to reach for you
“no… please- please i’ll be good, please let me cum”
“that’s up to jaemin, you only get cum if he says”
both sets of eyes turn to you, you give jaemin an inviting look and he walks back round next to you
“you said you wanted to get involved, how’d you want him?”
“on his knees”
you don’t wait for another instruction, just tugging haechan by the hair to bring him fully to his knees and jaemin stands behind him, manoeuvring his body to face the couch
“take a seat yn-ah, as much as he sounds pretty, i need him quiet, and you deserve a break after your long day, sit in front of him”
you do as he says, sitting down on the couch where haechan was just minutes ago, spreading your legs and tapping the tip of the toy at his lips.
“you’re gonna suck that dildo until i tell you to stop, and you’re only gonna cum when i tell you, you understand?”
“mhm”
jaemin leaves a harsh smack across the older boys ass, the impact has him wincing, a pink handprint already starting to glow
“use your words and stop being a brat”
you tug at his hair again making him look up at you
“stop showing off in front of jaemin, you wanted to be a brat and now we’re fucking you like one, and don’t give me that pathetic embarrassed look, you and me both know you’ve always wanted him to fuck you like this, that’s why you tell him all about our sex lives, you want him to know you’re a little cry baby who loves getting stuffed full, so be a good boy, and listen to him, tell him you’ll be good for him”
“i-i’ll be good for you”
jaemin runs a rare soothing hand down haechans spine before gesturing to the lube again, you pass it over and watch as he takes himself out of his pants, pulling them down to his mid thigh and coats himself in a thick layer of the gel before lining himself up with haechans hole, once puckered and tight now gaping and contracting after your previous round. jaemin squats slightly to get the right height and angle before he pushes in completely and before he can cry and scream too much you shove his head down on the toy, choking and gagging him as he starts to suck on the plastic. haechan looks up at you through his wet lashes as tears still streak down his cheeks, eyes red and puffy as his head bobs on its own like second nature. his body jerks as he feels jaemins hand snake around his front and grabs hold of his dick, one hand still firmly held onto the chain of his cuffs keeping him from collapsing fully forward from lack of balance. the stimulation on his shaft and gspot has his mouth watering around the strap, coating the crotch and thighs of your work clothes, but you don’t care, just watching your best friend fuck your boyfriend as he sucks off your strap on is enough to clear your head of any other thoughts. he gags louder and harder, thick layers of white bubbly spit smearing on his chin and nose as he continues to go to town. after bringing your boyfriend as close to the edge as he can get before pulling out, over and over, he can tell by the sounds he’s making, the lack of tension in his shoulders and back that his attitude has fully subsided and is now replaced by a softer and obedient manner, jaemin brings himself to orgasm first, unloading into haechans ass, despite being fucked by you countless times with your strap, he’s never felt the feeling of a dick cumming inside of him and the feeling is so new and different it leaves him shuttering, subconsciously deepthroating the toy as his body freezes and he feels the warm sticky feeling inside of him. haechan can’t help but wonder if this is how good you feel whenever he cums in you. jaemin keeps up a few more thrusts before speaking again, he can feel haechan is on the verge from just how tight he’s clenching
“alright, cum for us baby, keep sucking”
haechan moans into the silicon, the toy muting him as much as it can with it still lodged down his throat, its raspy, strained and broken as he cums into jaemins hand.
“keep sucking, that’s it, good boy”
jaemin gets fully down on his knees beside him, cum coating his fingers and palm, the hand on his cuffs pull him back softly from your strap. his own body language replaced by something more gentle and tentative.
“good, you did so good for me baby, now can you clean me up? lick yourself off my fingers”
jaemin pushes 3 fingers into haechans mouth slowly replacing the plastic and he gets to work sucking and slurping up his own cum as jaemins cum slops out of him from behind. you watch quietly as haechan nuzzles into him as he sucks himself off his fingers, licking his palms. he’s much more relaxed now, not the big attitude from earlier on in their day, no snarky remarks, just haechan fucked out and stretched open on your living room floor, obedient and pliant for you and his best friend, jaemin grabs the key for the cuffs before letting haechans wrists free and they lazily drop to his sides and jaemin pushes his hair back off his face like before as you watch quietly
“what do you say to nana?”
“thank you nana…”
“hmm, it’s okay baby, say thank you to your girlfriend, she did most of the work”
“thank you princess…”
you lean down from the couch to where he sits like a puddle on the floor still completely naked and give him a kiss, your hand gently cupping his face, helping him while he writhes in subspace,
“you did so good for us baby bear, maybe you’ll think twice about mouthing off?”
he nods yes with his big tear filled eyes, but you and both men know, it definitely won’t be long before you have to teach him the same lesson.
