Kim Seungmin has never relaxed in his life.

Jeongin knows this better than anyone, naturally, being the person that he liked to think knew Seungmin best. Sure it was debatable, but Jeongin would happily counter anyone’s objections to it.

Jeongin knows Seungmin is the type of person to give and give and give, to try so hard to constantly be better, that he won’t notice himself running out of things to give away.

Seungmin is kind, attentive, subtle about his positive qualities because he does good things purely out of innate goodness, and not for any sort of validation.

Jeongin thinks he still deserves the approval though. No matter how much of a tsundere little brat he could be. (Affectionately.)

It started with an offering. A casual offering, one that could be brushed off and forgotten and hopefully not ruin a perfectly good friendship if Seungmin wasn’t interested-

“So.. you just want to.. suck my dick? No strings attached?” Seungmin had said, eyebrows furrowed and eyes confused in a way that was so, incredibly endearing. “..Because I’m stressed?”

Jeongin remembers being very calculated in the way he shrugged carelessly, “Yeah. If you wanted, it’s whatever.”

Seungmin had said yes.

To be entirely honest, Jeongin was terrified for a few moments. Not only had he never sucked a dick before, he’d never even kissed someone for more than a few minutes, so it was a big leap. But, he had offered, and above that he really, really wanted to.

So he did.

He improvised his way through his first ever blowjob, closely watching the way Seungmin responded to everything. He liked the way Jeongin swirled his tongue around the head, so he did it again. He liked the way Jeongin had pressed his lips firmly around him, cheeks hollowed, so he went down further. He liked the way Jeongin moaned around him when Seungmin bucks up, and he can tell Seungmin likes it when Jeongin swallows his cum.

Jeongin tells him after that he’d do it again, if Seungmin ever got stressed and wanted it. He’s honestly surprised that it doesn’t take long for Seungmin to want it.

So they start a little routine—Seungmin works himself up, gets exhausted and stressed, comes to Jeongin’s room.

Jeongin blows him, gives him the occasional handjob if he’s feeling lazy, and that’s how it starts.

After a while, Seungmin insists on getting him off too, which Jeongin hadn’t really considered yet because he enjoys giving so much, but he allows it because how bad could it be?

Not bad at all, is the answer. In fact, it’s really fucking good.

Seungmin looks even better than he’d expected with his lips around Jeongin’s cock—he looks hungry for it, like he’d been waiting for it. He maintains eyecontact the entire time, moans when Jeongin pulls his hair, and Jeongin cums harder than he ever has with his hand.

Things evolve again, and it becomes more frequent.

Seungmin grinding against him in Jeongin’s lap, lips pressed to his and hands carding through his hair.

Jeongin’s hands on Seungmin’s hips, pining him to the couch as he eats him out like he’s starving for it.

His fingers working Seungmin open until he’s cumming untouched, letting Jeongin lap up the mess.

Weirdly enough, it doesn’t change their friendship much. Sure, they touch a bit more and their conversations sometimes have.. layers of subtext they hadn’t before, but other than that it feels normal. Like nothing had changed..

Until it does.

There’s one day that Seungmin and Jeongin are both in the kitchen, the other members out and their hips bumping as they wash and dry dishes respectively.

It’s domestic and mundane, but Jeongin doesn’t think anything of it until Seungmin’s leaning into him a little, back to his chest, craning his neck back to give Jeongin a kiss.

It’s… way different. It’s soft, so soft, and there’s not a hint of heat or expectation of what’s to come. Seungmin had kissed him just to kiss him, and that changed everything.

Suddenly Jeongin started seeking him out for more than just a quick handjob or earth-shattering head. He started to climb into Seungmin’s bed, arms wrapped around his waist and face buried in his neck. Soft.

Seungmin will barge into the bathroom when he knows Jeongin’s showering, gets him off slowly while they kiss against the tile. Intimate.

He starts to look at him different—not always a ‘I wanna make you cum in the coat closet’ look but sometimes a ‘I wanna make you laugh for the rest of my life’ look. Confusing.

It’s confusing. And a little terrifying. Mostly, it’s really good sex and a crush that kinda makes Jeongin feel like he’s dreaming.

“Innie, do you want to fuck me?” Seungmin says one night when they’re alone in the dorm, lips red from making out and voice gentle.

Jeongin thinks for a moment, takes a deep breath, and then nods, “Yeah. Yeah I do want to.”

───༺♡༻───

Jeongin watches Seungmin’s face closely as he falls back, naked against the mattress. He looks up at Jeongin with what he can only describe as ‘dazed focus’ — his eyes, dark and glassy, are trained on his, pink lips parted as puffs of air exit with every breath.

Jeongin climbs over him, knee slotted between his legs, and runs a hand up Seungmin’s waist and god is he a sight to behold.

“You look so pretty, hyung,” Jeongin mutters, because he really can’t stop himself. His ears burn at the way Seungmin whines, quiet and stifled, and his eyes flutter. He adores how responsive Seungmin is to the slightest of touches, the softest of words.

“Don’t be stupid,” Seungmin responds, and then because he’s Seungmin, “Are you gonna fuck me, or just stare at me?”

“Being demanding isn’t a good look on you, hyung,” Jeongin says with a smile, despite the blatant lie. It does look good on him. Anything does.

He slides his hands teasingly up Seungmin’s ribs and then to his arms, fingers wrapping around his wrists to pin them above his head. Seungmin sucks in a gasp and arches a little into Jeongin as he leans down, lips connecting to his neck.

“Stop teasing,” Seungmin’s pout is evident in his voice so Jeongin doesn’t even have to look, instead he grinds down, just once, relishing in the absolutely pathetic sound he makes.

“Stop being a brat, Minnie-hyung. I’m taking my time with you.”

And he means it, because Yang Jeongin is not a liar.

He takes his time kissing down Seungmin’s body, teasing his nipples with his tongue until he’s squirming under his touch. He always likes Seungmin best this way — squirmy, whining, desperate.

Jeongin nips at the soft skin of his waist, mouthing onto his hip and sucking a mark there. And then there’s two hands on Seungmin’s thighs, pushing them apart and up so Jeongin can kiss across those too.

He spends so long marking up Seungmin’s thighs, tongue lapping over the darkening skin. Seungmin is helplessly needy at this point, aching cock twitching and jerking when Jeongin’s lips find a new place to bruise.

Marks in general are risky with their jobs, and Jeongin knows he’s getting carried away, but Seungmin is writhing under him, fingers helplessly grasping at the sheets. Jeongin thinks this is worth the risk.

“Ah, mm, Jeonginnie,”

“I know hyung, I’ll start prepping you,” Jeongin laughs breathlessly, leaning up and admiring his work. Jesus, he’s mauled this poor man. He doesn’t feel sorry. He presses his thumb on one of the bruises, watching at the deep purple-ish red lightens as he takes it away for a brief moment. Seungmin yelps but Jeongin doesn’t miss the way his cock bobs in interest.

Perhaps he knows Seungmin a little too well, at this point.

He shuffles until he can find the lube, making quick work of coating his fingers.

He pauses, looking expectantly at Seungmin, who’s eyes are currently boring into him, waiting.

“Yes, Seungmin-hyung?” He says, sing-songy. “What do you want?”

“Yang Jeongin,” Seungmin’s lips purse together and his eyes narrow, “Don’t be a tease.”

“I’m not,” Jeongin says innocently, punctuating his sentence with a gentle caress of Seungmin’s entrance, “What do you want, puppy?”

So maybe he is a tease. Sue him.

“Innie,” Seungmin whines, but it seems his horniness outways his pride, “Please, stretch me so you can fuck me.”

Jeongin smiles, a sadistic curl of the lips, and pushes his middle finger inside him. Seungmin mewls and his hips push down a bit against him, chasing his touch.

“See, wasn’t so hard to just ask nicely, hyung.”

“I hate you.”

“What was that?” He curls his finger and Seungmin squeaks, any clever comeback dying on his tongue.

Jeongin’s pumps his finger slowly, carefully, as Seungmin adjusts. It doesn’t take too long, so soon enough Jeongin’s pointer finger is joining the first.

The moan it pulls from Seungmin’s throat is delicious, and so is the look on his face, all furrowed and wanting.

“I could do this forever,” Jeongin says softly, more to himself than to Seungmin, scissoring his fingers apart more and more to stretch him.

“You — mmm, can’t though,” Seungmin retorts, “I want to cum on your cock.”

“Oh my god,” Jeongin says, in english, his breath being punched out of his lungs. “You are depraved.”

Seungmin’s eyes become just a little clearer and he smirks, “You love it.”

Jeongin tsks and his free hand rises up and then plummets downwards, the slapping sound loud against Seungmin’s thigh.

Seungmin shudders and his hips buck a little, a soft ‘hah’ slipping from his mouth. Jeongin loves turning Seungmin into this — the man that will be a brat and a bother just amuse himself, reduced to a mess under him. He’s quickly growing addicted to it.

The third finger has Seungmin’s cock leaking precum, releasing soft pitchy whines with every pump and twist.

“Think you’re ready, hyung? Ready for me to fuck you until you’re nothing but putty in my hands?”

Jeongin surprises himself sometimes, with how easily the dirty talk has started to flow. At this point he thinks he’s say anything to waist the way Seungmin reacts, always so physical and dramatic.

“Yes—I’m ready, fuck me Jeonginnie..”

And fuck why hasn’t he done this sooner?

He pulls his fingers out slowly, thumb rubbing gently over the stretched skin of his entrance as he eases them out.

Jeongin rips open the condom wrapper the second he gets his hand on it, leaning up on his knees and scooting closer as he rolls it on. He’s generous with the lube too; he wants it to be good for Seungmin. Needs it to be.

Seungmin’s legs lift for him expectantly, wrapping loosely around Jeongin’s hips—it’s then he sees the damage on his thighs, marks already turning purple littered across his ivory skin.

“Fuck, Jeongin, what did you do to me..” He says, and his voice teeters towards amused instead of annoyed.

“Do you like them?” Jeongin asks, low and teasing, dragging his finger across one of them lightly.

“Yeah,” Seungmin says honestly, “Kinda wish you could give me more.”

Jeongin smiles immediately, “Oh yeah?” He purrs, inching forward even more to nudge the head of his cock against his hole, “Wish I could mark you where people could see? Let people know you’re mine? Belong to me?”

Seungmin whimpers, honest to god whimpers, and nods quickly, “Yes, yes, fuck.”

“That’s what I thought,” Jeongin pushes inside him in one quick, fluid movement, Seungmin’s hands scrambling to clutch at him.

“Oh—Oh my god,” Seungmin gasps, his nails already digging into his shoulders. Jeongin finds he kind of likes how it stings—kind of really likes how it stings.

“I like that—the uh, the nails,” Jeongin mutters, still not moving his hips has Seungmin gets adjusted to the stretch of his cock.

Seungmin hums in acknowledgment, digging them in a little harder, “You like a bit of pain too, Innie? Looks like we have that in common,” Seungmin’s fingers curl around his nape and then slide up, threading through his hair and then tugging, “Do you like that too?”

Jeongin groans, and fuck, he does, because his cock twitches and he shivers and Seungmin giggles a little, breathless.

“Jeongin-ah, you can move now,” He says, tugging him down and peppering kisses across Jeongin’s jaw. “Please fuck me- ah!”

Jeongin pulls out and snaps his hips forward, hissing at just how tight, now warm Seungmin feels around him.

He starts to build a slow, rough pace, bathing in the moans and whines from Seungmin’s lips, fueled by the way his thighs tremble and his fingers tug at his hair.

He’s handsy with Seungmin, greedy, fingers prodding and squeezing at his waist, his nipples, across the bites on his thighs. He tugs at his cock a few times but Seungmin whines and bats his hand away, says he’ll cum too fast.

Jeongin’s glad for the warning because he wants this to last, wants to fuck Seungmin until there’s a permanent dip in the mattress from his body being pressed into it.

He wonders, somewhere deep in his brain, if he could pay Hyunjin enough money to paint them fucking. It’s a ridiculous idea, and Jeongin knows he’d fucking hate that realistically, but it’s about immortalizing this moment. He wants it to last forever.

The hand that’s been clasped against Jeongin’s shoulder starts to paw needily down his back, and Jeongin feels the sharp scrape of his nails again. Addictive.

“You feel so good, Seungmin-hyung, so perfect on my cock,” Jeongin mutters into his skin, words flowing out easier than an exhale.

“Innie — yes, ah — fuck-“

Seungmin’s voice is gravelly and unstable, his entire face contorted as whines punctuate every thrust. His entire face is flushed red, pupils blown as he looks at Jeongin with this cute, fucked out expression.

He finally understands the meaning of ‘fuck your brains out’, because Seungmin looks so dumb and cockdrunk that Jeongin suddenly wishes he wasn’t wearing a condom. He has the sick, insanely unhinged thought of claiming him in that way, watching his cum trickle out of his hole. 

Jeongin thinks being with Seungmin is poisoning his brain. Like some sort of sex parasite. Whatever he is, Jeongin is too far gone to think of letting it go.

He wants to bottle up this feeling—make it so he never stops hearing those noises leave Seungmin’s lips, never stops being the reason for him to tremble and shiver against him.

“Jeong—please, Innie-!”

Jeongin speeds up even more, his thighs burning from how hard he’s fucking him and yet he can’t stop, won’t, because he can see tears slipping from Seungmin’s eyes and his nails have definitely broke skin on Jeongin’s back and—

Okay. Jeongin thinks he might be in love.

The hand in Jeongin’s hair tugs, hard, and then Seungmin is cumming with a broken sob, painting his stomach and a bit of his chest.

His body convulses and jerks in a way that for a second has Jeongin concerned, nearly moving to pull out, but Seungmin’s legs lock around his hips and he’s pulling Jeongin further, deeper, nails still sliding across his skin like he has something to prove. To claim.

“Go on Innie—ah—cum inside me-“

Jeongin sputters, currently too blissed out to point out or remind Seungmin that he kinda can’t because, you know, afformentioned condom. It doesn’t seem vital in that moment anyway, with Seungmin’s soft ‘ah ah ah’ in his ear as he contributes his movements.

It doesn’t take long to finish, not with Seungmin clenching around him and whimpering with overstimulation and yet still clinging to him like he can’t get enough.

“Seungmi-“ Jeongin’s words fall apart as he moans, spilling into the condom and panting heavily.

His eyes wrench closed for a moment and when he regains his breath a little he opens them.

Seungmin’s staring up at him, eyes sparkling in the way they usually do when he’s looking at a crowd of stay’s or a particularly pretty sunset, still a little glassy from crying and so incredibly fond.

“You look so pretty when you cum.”

Jeongin feels his ears get hot and he feels the carnal need to shove him, curl in on himself like he usually does with random compliments. He doesn’t though, because this is Seungmin.

Seungmin, who doesn’t say anything sweet unless he really means it.

Seungmin, who is quite possibly one of the most talented people on the planet.

Seungmin, who is ruled by honesty and a deep-seated need to make other people smile.

Seungmin, who Jeongin is hopelessly, terribly, and utterly in love with — and Jeongin’s never been good at keeping a secret from him.

“I’m in love with you.”

It kinda comes out all in one word, rushed and pushed out before he could stop it.

Seungmin blinks up at him once, twice, and then a smile blooms on his face and he’s laughing, “It’s just like you to say something like that right after sex. You’re an idiot,” He tugs Jeongin in, kissing him so softly it may as well be a figment of his imagination, “I am too—In love with you I mean, not an idiot.”

Jeongin can’t help but grin, and he shakes his head, “No. You’re an idiot too, hyung.”

Seungmin just smiles and kisses him again. 

It’s not so scary, being in love with Seungmin - sure it requires a steady hand to handle someone else’s heart, and a whole lot of patience. But Jeongin’s never lacked the want to try. To grow. To evolve.

It’s nice to catch Seungmin’s eye in the mirror during dance practice and feel the flutter in his chest. Nice to pin him to the wall in the showers and fuck him stupid. Nice to be in his space. To be with him. Be loved by him.

Overall, Jeongin would give falling in love 5 out of 5 stars.

“Um?! Jeonginnie, did you get mauled by a bear? Chan-hyung, look at the scratches on Jeongin’s back—“

Okay. Maybe 4.9 out of 5.
