Work Text:
Jimin feels like he should be knocking the door to let Namjoon know that he’s about to come in. He has his knuckles against the door and everything before he realizes he’d just be making a fool out of himself. It’s one of the bedrooms in their dorm that he’s about to step into, not the CEO’s office.
Namjoon’s laying on his bed, the lower bunk of course since he’s rooming with Jungkook, and the younger members always take the top ones. He’s reading, big earphones covering his ears, and the whole room echoes with the low, lazy beats leaking through the speakers. He looks relaxed in his loose boxers and t-shirt, a little sleepy even. It makes Jimin reconsider walking inside. It's not like they get a lot of time for relaxing with their more than hectic schedule, especially Namjoon.
But Namjoon left the door open and he's reassured Jimin before, petted his cheek and chuckled at his uncharacteristically polite words.
“Hi hyung,” Jimin says as he steps inside and gives an awkward little wave, even though Namjoon most likely can’t hear him through the music and his eyes are glued to the book. When he reaches the end of the page and lifts his hand up to turn to the next one, he startles a little and his eyes snap up to meet Jimin's.
Jimin rubs the back of his neck, embarrassed and waiting to see how Namjoon will react. There’s not even a shred of doubt he won’t immediately guess why Jimin is there, just as always.
“What’s up?” Namjoon says, pushing the earphones away from his ears. He ruffles his hair, and Jimin swallows, fingers worrying the hem of his loose t-shirt.
Any words of explanation are suddenly stuck in his throat and refuse to move, so Jimin just kind of hangs there next to the door frame and wills Namjoon to understand with uncertain looks and awkward fidgeting. Of course he gets it in a matter of seconds, just as Jimin predicted, or maybe he already guessed and he's just teasing Jimin. Wouldn't be a surprise judging by the grin that splits Namjoon's face and how his body relaxes against the pillows again, legs spreading a bit wider. He's making space, already expecting Jimin.
“Just come here already. Oh, close the door, though, okay? I don’t mind but you might.”
Jimin snickers to himself, half embarrassed and half amused, as he pushes the door shut as quietly as he can and moves closer to the bed. Sometimes Namjoon talks about it, letting others see, inviting them, always easily and as if he was just joking. Jimin has started to suspect he has some kind of an exhibitionism kink.
Jimin, on the other hand, doesn’t really know what he thinks. It’s easier to let Namjoon decide. Namjoon, who always knows when to push, shove just hard enough to get past any resistance. Who also knows how to give and what Jimin wants to be given.
“Thanks, hyung,” Jimin says, quietly and under his breath, as he flops down onto the bed and crawls between Namjoon’s thighs.
“Feeling restless? Nervous?” Namjoon asks and reaches out to touch the back of Jimin’s neck. His fingers slide down to linger on his jaw and stroke the skin there, then his lips and his soft, still too round cheeks. It makes Jimin feel safer and he smiles, leaning shamelessly forward for more.
“Tsk, just horny then, I take it."
“A little,” Jimin finally replies, flushing, and touches the edge of Namjoon's t-shirt. His fingers hesitate for a moment and then slowly sneak inside the waistband of Namjoon's boxers and pull them down. Not completely off, but just so that it’s easier to take Namjoon’s cock and balls out. Give himself a better access to his prize.
“Do you mind if I keep going? Just got to a really good part,” Namjoon asks, eyes on Jimin’s face and right hand still caressing his neck, but the left one waving the book he’s holding.
“Yeah, sure. Of course,” Jimin says immediately, nodding and waiting until Namjoon gives him a final pat on the head before his hand falls, settling down on his belly. That’s all the permission Jimin needs; now he can duck down, get comfortable on his stomach and finally press his lips against the head of Namjoon’s cock.
“Gonna leave the headphones off. I like listening to you,” Namjoon says, already a little distant and concentrating more on the text than on Jimin. It’s okay, because he doesn’t expect an answer and Jimin’s not really there to have Namjoon’s attention on him, no matter how much he might like it.
Jimin has hard time hiding his moan when gets the first taste of Namjoon’s cock, but he manages. He doesn't get to savor the taste for long, though. Namjoon is supposed to be absorbed into his book, but suddenly he's reaching out and giving Jimin's hair a little tug, pulling him up for a couple of seconds so that Jimin can’t reach his cock anymore. It’s just to remind him of what Namjoon just said, Jimin guesses. He stupidly thought that Namjoon would let it pass this time.
It’s a rule. Jimin should always make noise, but most of the time he’s still too embarrassed and needs a little nudging. He just can’t help feeling like all the other members can hear him, like they’re waiting outside the room with their ears pressed against the door even now.
“Um, sorry,” Jimin mumbles against the side of Namjoon’s cock and gives it a long lick, just to apologize. Then he waits for a couple of seconds in case Namjoon wants to say something, but when he just turns another page, Jimin relaxes again.
He starts coaxing Namjoon into hardness, without any hurry because Jimin wants this to last. And as long as he doesn’t tease, Namjoon's okay with it too.
As if reminding Jimin not to forget again, Namjoon keeps his hand on top of his head, caresses his hair. Jimin feels like moaning again just because of the feeling. After a moment of hesitation he does moan, a bit shyly, and Namjoon tugs at his hair again, but Jimin thinks that now it’s approving instead of chiding. A silent, careless praise that makes his toes curl and stomach flip.
Jimin doesn’t stop licking until his heartbeat is completely calm, body lax and mind blissfully empty. By then Namjoon is fully hard, cock heavy and hot and waiting in Jimin’s small fingers. It’s only then that he allows himself to wrap his lips around the head and finally suck the cock into his mouth. It makes his cheek bulge before sliding towards Jimin’s throat, exactly where he craves it.
Namjoon’s grip on his hair tightens and Jimin hears him make a small, breathy grunt above him. He tongues the underside of Namjoon’s cock, lets his lips drag along the crown when he pulls his head back, just to see if he could hear that sound again.
Of course Namjoon has too good control for something sloppy like that. He leaves that part to Jimin, who pants around his mouthful like a bitch, like he’s starving for more.
“Slowly,” Namjoon murmurs from above, and just the rumble of his voice has Jimin’s eyes fluttering shut, his heartbeat picking up again. He swallows around the cock head in his mouth and then just waits, rides the slight burn and sting behind his eyelids. Jimin doesn’t back off until Namjoon turns another page, but doesn’t risk letting Namjoon’s cock completely out of his mouth when he pulls back.
Spit pools at the corners of his mouth and Jimin wants to wipe it off. His hands flex against Namjoon’s hips but don’t move. Instead he just laps up the pre-come from the slit of and concentrates on the taste, tries not to think of himself.
He goes back to bobbing his head up and down, his pace lazy and unhurried just like Namjoon wants it when he's reading or writing lyrics. If Jimin himself has to dig his heels in and fight not to suck and lick and slurp until he finally gets Namjoon’s come in his belly, that's his own problem. He wants to stay between Namjoon’s legs as long as he can, despite his impatience, and Namjoon is giving him just that.
Forcing himself not to hurry, Jimin swirls his tongue against the shaft, caresses the soft skin. Even though he’s laying down on his front, relatively comfortable, it feels like he has to strain and fist the bed covers just to stay still. He’s too damn thirsty to wait, but he should try to think, be a bit smarter like Namjoon.
If he waits, he gets to feel the weight of Namjoon’s cock and taste his pre-come a little bit longer. His mouth will be full for a few more minutes.
Jimin is licking the cock head with tiny kitten licks, not too much pressure, when Namjoon finally pets his head to get his attention and then grips the black locks hard enough to make Jimin stop moving altogether.
Above him, Namjoon puts the book down and leans back, spreading his legs a bit more. He relaxes and pushes Jimin’s bangs back from his sweaty forehead, and Jimin knows that now he can let go.
Now that Jimin can truly concentrate on sucking Namjoon’s cock and the intoxicating feel of it bumping against the back of his throat, he can finally forget about his erection. It was hard to ignore before, when he had to force himself to slow down. He’s been half hard since he stepped inside the room and the first taste of Namjoon on his tongue was all he needed to start feeling truly uncomfortable in his boxers.
But it’s also an important part of the deal; he doesn’t come before Namjoon does.
He pushes his hips down against the mattress, but doesn’t hump it even if his cock is throbbing for just a tiny bit of touch. It’s not allowed, first of all, and secondly it would be just horribly embarrassing, with Namjoon watching him behind half lidded eyes and a small smile tugging at the corners of his mouth.
So Jimin just concentrates on sucking and swallowing and using his tongue the way he has practiced. His whole body tenses with anticipation when Namjoon throws his head back and his cock twitches. He's so damn hard and dripping so much pre-come that Jimin’s whole mouth feels slick enough for it to run down from his lips.
He gives one more hard suck, cheeks hollowing and lips and tongue rubbing against the shaft of Namjoon’s cock, and then Namjoon grunts and pushes his hips up from the bed. Finally Jimin's mouth is filled with come.
No matter how much Jimin loves to choke on Namjoon’s cock, he never wants to deep throat when Namjoon comes. He wants to have all that spunk on his tongue so that he can swallow it down and down, feel like it’s never going to be over. It’s dirty, but he wants it to drip down his chin so that Namjoon will swipe it off with his thumb, chuckle and then massage it into Jimin’s skin with strong fingers.
Jimin’s eyes flutter shut and fuck, he’s so hard, so close himself already. His hips tremble, but he knows to stay still now, not even swallow after the last spurt of come hits his tongue. Namjoon is sensitive right now and needs a little time to recover.
Spit pools inside Jimin’s mouth as he waits, lips still wrapped around Namjoon’s cock. Then Namjoon cups the back of his head and just holds him there, not making Jimin back off but instead giving another wordless permission.
Jimin bends one knee and cants his hips so that he can wiggle one hand under himself and into his pants. It’s uncomfortable and there’s not enough space for proper movement, but he’s able to give his cock the few touches it needs; two hasty strokes, a twist of his wrist, and then Jimin’s coming in his boxers. He moans around Namjoon’s cock, pants and shakes and rides the aftershocks that have him seeing stars.
Coming down from his orgasm, Jimin becomes aware of things other than his sticky underwear, overly sensitive dick and Namjoon’s cock on his tongue. His brain feels fuzzy and body so relaxed, like he could stay there forever. Probably could, to be honest. Namjoon is still watching him and smiling that lazy smile that makes his dimples pop.
“You have,” Namjoon says, squinting at the alarm clock on the table, “Fifteen minutes, I think. We got dance practice and I think you might wanna clean up a bit.”
Jimin wants to protest, because fifteen minutes is nothing and he wants more, needs more. But his words are muffled and completely incomprehensible, and Namjoon just pets his head and grabs his book again. He finds his mark easily, already immersed in the text again within seconds, it seems. Jimin steals a glance at his face and then dares to swallow. He should have given himself and his gut instinct more credit, because Namjoon doesn’t react, just absentmindedly cords his fingers through Jimin’s hair.
It’s too late already, since Jimin’s chin has got to be all messy with spit and come, but he tries to wipe of some of it and makes himself more relaxed around Namjoon’s cock. He swallows every now and then and makes sure his teeth won’t accidentally scrape skin. Closing his eyes and resting his cheek against Namjoon’s thigh, he feels sated and content enough to lose all sense of time and place.
“Up,” Namjoon says after a while, probably since the fifteen minutes he promised have passed. Jimin pulls off, reluctant and wanting to drag it on as long as possible, but climbs up form the bed when Namjoon gives him an amused look and a tap on the forehead.
“Thanks,” he says and smiles. He feels shy because Namjoon is tugging himself back in his pants and Jimin is just staring, his mouth still tasting like Namjoon’s come. All he wants is to get back down and swallow him to the hilt. He licks his lips without thinking and it makes Namjoon reach forward and stroke the nape of Jimin’s neck.
“Guess what Seokjin-hyung asked me a couple of days ago?” Namjoon says while stretching his hands above his head, all casual and smiling.
“What?”
“He was curious about what we always do together like this, all secretive behind closed doors.” Namjoon grins and rests his hand against Jimin’s neck again. It's a favorite for the both of them and Namjoon makes sure to stroke that spot as often as he can. “Maybe he could help you out too. You know, if I’m busy or have to be at the studio or something.”
Jimin swallows, his heart suddenly racing faster and faster and cheeks turning a cherry shade of red.
“Seokjin-hyung would be really good. A big help,” Namjoon says and chuckles, a meaningful glimmer in his eyes. “I think you should ask him.”
