Summary
     landing himself a detention turns out to be the best part of jimin's
     day.
Notes
     ty to my baby girl gangbang for reading this over for me and assuring
     me it's not terrible;; ♡
Jimin sighs, staring out the window. He’d landed himself in detention, having
skipped math to meet Namjoon in the second floor boy’s washroom. The school
body president hadn’t gotten in trouble, of course, he had a free period but
Jimin's math teacher had caught him in the library on his lunch, given Jimin a
disparaging look as he told Jimin he had detention.
A part of him tells him to count his lucky stars, considering anyone could have
walked in on him and Namjoon, Jimin’s pants pooled around his ankles, Namjoon’s
mouth on his cock. A certifibale disaster, if they’d been caught by a teacher.
Still, he’d rather not be spending his afternoon caged up in detention, not
when the sun is teasing him through the windows, warm rays keeping Jimin toasty
as he drapes himself over his desk, eyes fixed on the black chalk board. What
was the point of detention? Were you supposed to become a better person while
being bored out of your mind? Jimin’s really only mad because he could be at
Namjoon’s right now, acting out a sequel to their washroom adventures.
Namjoon had given him a smirk when Jimin had told him, cooing at his pout and
telling Jimin he looked really cute when he was upset. Unhelpful as that was,
they’d squeezed in a quick make-out session after their last class, and maybe
Taehyung was right. Maybe Jimin spent too much time thinking about fucking and
shoving his tongue down Namjoon’s throat but Jimin couldn’t be blamed for
hormones and a boyfriend who enjoyed shoving his hand down Jimin’s pants, even
in public.
“This is so boring,” Jimin mutters, wondering when the detention supervisor
would show up. Literally no one else is in the classroom and that’s ridiculous.
Jimin can’t be the only bad apple in the school.
“Is it?” a voice says from Jimin’s right and he whips around to find Namjoon
standing in the doorway, school blazer slung over a shoulder, tie loosened up.
His hair’s still perfectly styled, not a strand out of place, swept up out of
his face, but he’s rolled up the sleeves of his dress shirt until they sit at
his elbows and Jimin’s mouth goes dry.
“What’re you doing here, hyung?” Jimin asks, brows furrowed together. It’s not
that he minds, just that Namjoon has about a hundred different obligations and
responsibilities.
Namjoon tuts, moving out of the doorway and letting the door close behind him.
He drapes his blazer over a desk before making his way over to Jimin, taking a
seat on the desk in front of Jimin.
“Is that any way to talk to your detention supervisor, you delinquent?” Namjoon
grins, dimple curling into his cheek and Jimin’s eyes widen, smile spreading
wider and wider across his face.
“Really?” he exclaims, nearly giggling because suddenly the idea of having to
sit in an empty classroom for forty minutes didn’t seem so bad. He leans
forward in his seat, grinning up at Namjoon who’s trying very hard to hold back
his smile but doing a terrible job of it.
“Really,” Namjoon answers, reaching forward and pinching Jimin’s nose. “But you
owe me, Park Jimin. I had to give up my lunch tomorrow.”
Jimin wrinkles his nose, pulling away from Namjoon with a frown. “Why?” And
it’s probably terrible that Jimin is more upset that he won’t get to spend
lunch with Namjoon, despite the fact that he normally made a sizable dent in
his homework when Namjoon wasn’t around. Still, Namjoon always caved and fed
bits of his lunch to Jimin as they worked, let Jimin slump against him, whining
about his classes.
“Because,” Namjoon says slowly, school genius always condescending at the worst
of times. “My boyfriend got caught by his math teacher for skipping.”
“Who’s fault was that?” Jimin counters, ready to stick his tongue out at
Namjoon.
Namjoon raises an eyebrow, and Jimin’s always found that alarmingly hot, but
now’s really not the time. “I would think it’d be yours. I’m not the one in
detention.”
“Oh? Well, I guess I won’t be skipping math ever again,” Jimin snips, nose
upturned as he looks away from Namjoon. He doesn’t miss the snicker that
escapes Namjoon, or the way his shoulders look so broad in his dress shirt.
It’s quite unfair.
“Last I checked, you got the better end of the deal. I even came here to keep
you company,” Namjoon points out, but Jimin doesn’t want to give him the
satisfaction of knowing he’s maybe a little bit right. Jimin did get his dick
sucked and Namjoon was kind of amazing at it.
“I didn’t drag myself to the washroom, you know,” Jimin counters, eyeing
Namjoon out of the corner of his eyes. He ignores the stretch of Namjoon’s long
legs, the cocksure grin Namjoon’s wearing as he plays along.
“Mmm, you’re right, hyung’s being mean, isn’t he?” Namjoon agrees and Jimin’s
giving him a sharp, suspicious look. That was a little too easy.
“Y-yeah,” Jimin answers, a little thrown off and Namjoon’s leaving his seat to
settle on the edge of Jimin’s desk, his legs trapping Jimin in his seat. He
grabs Jimin by the tie, tugs him forward, wrapping the tie around his hand.
“Come here,” he murmurs, pulling Jimin to him, licking his mouth open until
he’s got Jimin sighing into him, body melting forward. “Hyung’s sorry.”
“F-for what?” Jimin stutters, a little breathless as he stares at Namjoon’s
mouth, eyes half-lidded.
"Didn't you get detention because of me?" Namjoon asks, eyebrow raised and he's
smirking again. It's insufferable. Jimin scowls, trying to pull back a little
even as he lets his hands come to rest against Namjoon's knees. His legs are
impossibly long, and Jimin likes sitting against them when they're at Namjoon's
place or his, nestled between them. Something about it makes him feel so
secure.
"You're being condescending," Jimin retorts, scowl still there.
"Am I?" Namjoon's trying to act innocent, as if he doesn’t know exactly what
he's doing. Jimin finds that even more annoying.
"I thought you'd want to do home and start studying," Jimin says instead,
purposefully changing the topic.
“Studying? Is that what you’re calling wanting to suck my dick now?” Namjoon
smirks, and Jimin really just wants to maybe punch him in the face. Why had he
decided to go out with this asshole again?
"Do you take perverse pleasure in being an ass?" Jimin asks, pushing Namjoon's
hand away and off his tie. He leans back in his seat, staring up at Namjoon
who's still got this smug air about him.
"You're getting really mouthy, baby," Namjoon comments, a hint of disapproval
colouring his tone. Jimin would never admit it, but he rather likes how Namjoon
sounds when he's not entirely happy with Jimin. In fact, Jimin likes that curl
of tempered anger.
"Am I?" Jimin imitates and it's enough. Namjoon grabs him by the tie again and
it goes straight to Jimin’s cock, the way he looks at Jimin with distaste, the
tie tightening around his throat.
"Oh, you think you're gonna try that tone with me," Namjoon hisses. Jimin only
licks his mouth, relishing the way Namjoon's eyes have narrowed.
“I thought you liked it when I was loud,” Jimin breathes, shamelessly letting
his hands drag over Namjoon’s thighs, thick muscle from years of track, hard
and thrumming under Jimin’s fingers. Namjoon’s hand fists into Jimin’s hair,
tipping his head back as Jimin’s fingers skate over the zipper of his pants,
tracing over the shape of Namjoon’s cock.
“You sound like you need to be gagged,” Namjoon whispers, eyes darkening as he
leans down, devouring Jimin in a kiss, heated as he presses closer. Jimin’s
mouth falls open as Namjoon pushes his tongue past his lips, whimpering when
Namjoon loosens his hold on Jimin’s tie. Someone could walk in on them any
second, but fuck if Jimin cares, not when he’s ready to start rubbing himself
against Namjoon’s leg just to get off.
“Gonna give me your cock?” Jimin gasps into Namjoon’s mouth, moaning when
Namjoon bites down on his lip, sucking in the bruised skin until he’s satisfied
with the way Jimin’s panting.
“Who said anything about giving?” Namjoon smirks, batting away the hand Jimin’s
using to palm Namjoon through his pants. “Use your mouth, come on.”
Jimin knows what Namjoon means, doesn’t wait to be told twice before leaning in
to nose his way up the inseam, struggling to get the pull tab in between his
teeth. When he does, Namjoon rewards him with a squeeze around the base of his
neck, and he hasn’t choked Jimin out in a while, not since Jimin begged him the
last time. The idea flutters in the back of his head, dragging the zipper on
Namjoon’s pants open. Maybe tomorrow, they could skip last period, go to
Jimin’s house, fool around.
“You can go faster than this,” Namjoon says impatiently, pulling Jimin away
from his crotch roughly by the hair, the hard yank sending a shiver down
Jimin’s spine. He liked it rough, liked it when he had bruises to show for his
efforts, liked the scratches running down his back, his arms. Namjoon pulls his
cock out, half-hard as he strokes his length, watching Jimin with pursed lips.
“You gonna do this right, or you want me to leave you with your cock hard in
your pants?”
“Hyung, please,” Jimin whines, licking his lips, “I’ll, I just wanna suck you
off. Please?”
“Hands on my thighs, if they touch my cock, we stop,” Namjoon orders, and Jimin
nods, a little slow as his cock twitches in his pants, slow ache settling in
his gut. “Well?”
Jimin leans forward, eager, takes Namjoon’s length in his mouth, jaw slack as
Namjoon thrusts forward, fucking into Jimin’s mouth. He tries to keep up, rolls
spit into his mouth to keep Namjoon’s cock wet as he slides in and out of
Jimin’s mouth, cheeks hollowed out. When Namjoon lets the head of his cock
linger on Jimin’s lips, Jimin kisses the tip, lets his tongue swirl around the
head, fingers digging into Namjoon’s thighs as he licks the length of Namjoon’s
cock.
Smirking, Namjoon holds Jimin still, cock dragging across his cheeks, the
wetness of Jimin’s spit and Namjoon’s precum left behind as Namjoon’s cock
returns to Jimin’s mouth. Namjoon watches him, mouth hung open as Jimin
swallows the length once more, burying his nose into Namjoon’s pubes, the musky
scent of arousal and tucked away skin washing over Jimin. He hums around the
girth of Namjoon’s cock, knows Namjoon loves the tightness of Jimin’s throat,
and when Jimin swallows around Namjoon’s head, he groans, too loud, hand so
tight in his hair that Jimin’s afraid he might rip some of it out.
"Fuck," Namjoon shudders, groans deep and hoarse, and he had sucked Jimin off
earlier that day, taking Jimin's length all the way in. Jimin always struggles
to do the same, Namjoon's cock so big, his lips burn around the girth, stretch
impossible. "You're so good, baby. Wish I was fucking your ass right now, not
just your pretty mouth."
Jimin can't help the moan he lets out, vibrating around Namjoon's length and he
loves the way Namjoon can't keep quiet, head falling back as Jimin, cheeks
hollowed, sucks him in as far as he can go without gagging right off.
"Mmm, fuck, baby, you look so good sucking cock, like your mouth was made for
it," Namjoon exhales, hand loosening up in Jimin's hair and it's nice, the
constant pull starting to hurt.
Jimin flushes, feels the burn of embarrassment across his cheeks, spit
dribbling down his chin. He probably looks obscene, always does and Namjoon has
taken pictures before, Jimin's face covered in Namjoon's cum but he's never
taken a shot while Jimin's still got his cock in his mouth. Too distracted,
maybe.
Pulling off, Jimin swirls his tongue around the head, pushes into the slit to
taste Namjoon's precum on his tongue, salty and bitter. It's not the greatest
taste but Jimin likes it, likes the way Namjoon always bucks his hips up when
Jimin presses his tongue into his glans.
There's a loud yelp outside of the door and Jimin stills, startling. He nearly
pulls off but Namjoon holds him there, thumb stroking over Jimin's cheekbones.
“Did I tell you to stop?” Namjoon asks, unimpressed as he leans back, lets his
weight drop onto his free hand.
"Sorry, hyung," Jimin mumbles around Namjoon's cock head, licking down the
length of Namjoon's cock until he's at his balls. He knows how much Namjoon
likes having his balls sucked on, tongue lapping over the skin, sucking one
into his mouth.
"You'd like it if someone walked in, wouldn't you, Jiminnie?" Namjoon whispers
to him, and Jimin's squeezing his legs together at Namjoon’s words, tent in his
pants straining against the material. He's painfully hard and he wishes he
could touch himself but Namjoon doesn't like being disobeyed and Jimin hates
disappointing. "You'd suck my cock even if someone was watching, probably even
better, put on a little show."
Jimin lets out a little sob, panting as Namjoon pulls him off his cock, yanking
Jimin's head back until his throat's bare.
"God, you're so fucking beautiful," Namjoon murmurs, fingers tracing down the
length of Jimin's neck. "I just love wrecking you."
"H-hyung," Jimin whines, body trembling as he looks at Namjoon, takes in the
glisten of sweat on his skin. He looks golden in the sunlight streaming in
through the window, and they're lucky to be on the second floor where no one
can even accidentally see Jimin with cock down his throat.
"Let hyung fuck your mouth," Namjoon suggests, leaning down to kiss Jimin and
its sweeter than Jimin expects, a quiver settling in his stomach. "But only if
you think you can."
"I, I can," Jimin answers, eyelashes fluttering shut as Namjoon sucks his
tongue into his mouth, teeth scraping over the flesh.
"I'm so lucky to have such a good boy," Namjoon murmurs, pulling away from
Jimin. He nearly whines, opening his eyes to look at Namjoon again. His cock's
wet with Jimin's spit, precum dripping from the tip and Jimin can't help
himself, reaching forward to suck it into his mouth. Namjoon moans, cursing
under his breath as he cards his hand through Jimin's hair, petting him even.
Swallowing down Namjoon’s length, Jimin starts again, this time letting his jaw
stay slack.
Namjoon lets him bob up and down for a bit, before he's tightening his hand in
Jimin's hair again, holding him still as he lets his hips roll forward. He's
not rough, at least not yet, but Jimin's going to get salvia all over his
uniform, possibly even cum. He'd washed his blazer himself a few times, getting
increasingly suspicious looks from his mother with each wash.
"You ready?" Namjoon asks. Jimin nods, eyes shutting as he readies himself and
Namjoon picks up speed, fucking into his mouth. He hits the back of Jimin's
throat more regularly with each thrust in and Jimin's got tears prickling in
his eyes, gagging around Namjoon's cock as he groans into the empty classroom.
"Shit, shit," Namjoon hisses. "I'm so close, baby, fuck."
Jimin only squeezes his hands over Namjoon's thighs, tears slipping down his
cheeks as his throat gets fucked raw. He only knows Namjoon's about to come
from the way he tenses up under Jimin's touch, thrusts not nearly as smooth and
then Jimin's tasting cum, swallowing down what he can as Namjoon lets him fall
back, stroking his cock through his orgasm.
Leaving his mouth open, Jimin lets Namjoon jerk off on his face, peeking
through his eyes as Namjoon's cum splatters across his face, nearly getting
into his eye. There's a stripe across his cheeks, dripping down his chin and
Jimin's just sucking in deep lungfuls of air, swallowing whatever's on his
tongue.
"Fuck," Namjoon breathes, Jimin opening his eyes to find Namjoon with his head
thrown back, staring at the ceiling. Jimin hopes he has a handkerchief or
tissue or something.
On second thought, he waits until Namjoon's looking at him, smiling and Jimin
licks at his mouth, wipes cum from his cheeks and licks it clean off his
fingers.
"Shit," Namjoon rasps, grabbing Jimin's hand and pulling him forward roughly.
"You little fucker."
"You're so mean," Jimin whines, voice completely hoarse and he's surprised he
can make any coherent sounds at all. But Namjoon's not responding, closing the
gap between their mouths impatiently. Jimin opens up for him immediately, lets
Namjoon suck and bite at his lips, swallow down every moan Jimin lets out.
"You're so perfect," Namjoon tells him, smoothing down Jimin's hair. It's
probably a mess by now, sticking out every which way. He tucks himself back
into his pants, leaving Jimin in his seat to grab tissues from the front desk.
When he makes it back to Jimin, he pulls Jimin out of his seat, sititng in the
now empty seat and pulling Jimin into his lap. “You look so cute when you’ve
got my cum all over your face.”
Jimin wrinkles his nose, let's Namjoon clean up whatever’s still left on
Jimin’s face. “Cute? I don’t wanna be cute.”
“What do you wanna be?” Namjoon asks, voice soft and indulgent, hands running
up and down Jimin’s thighs. Jimin’s breath hitches when Namjoon’s fingers
slides too close to his still hard cock, heat pooling in his gut.
“Hot,” Jimin says, eyes fixed on Namjoon’s fluttering fingers, lip catching
between his teeth as Namjoon purposefully palms Jimin’s cock. He’s watching
Jimin with his full attention, in that way that made Jimin’s skin feel like
it's on fire.
“Hot,” Namjoon echoes. He’s undoing Jimin’s belt, popping open the button of
his pants, hand sliding up Jimin’s abdomen, calloused fingers rough against
Jimin’s skin. Loosening Jimin’s tie, he unbuttons the first few buttons of
Jimin’s dress shirt before leaning forward to suck against the exposed skin,
Jimin shuddering in his hold. Teeth sink into his skin, tongue lapping at the
bite Namjoon’s just made. He moves higher up, sucks against the curve where
Jimin’s shoulder meets his neck, nosing along Jimin’s neck when he’s satisfied
with the painful hickey he’s left.
“Hyung,” Jimin starts, hips rolling down against Namjoon’s, eager for some
friction. His cock’s aching, impatience getting the better of him. “You’re
teasing.”
“I just wanted to make my baby feel hot,” Namjoon says, sucking Jimin’s earlobe
between his teeth, tongue swirling around the stud Jimin’s wearing. “Isn’t that
what you wanted?”
“Yeah, but,” Jimin says, voice hitching when Namjoon pushes Jimin’s underwear
down, just enough that Jimin can feel the cool of the classroom against his
cock. He presses a finger into the slit, smirks when Jimin lets out a whimper.
“But what, Jimin?” Namjoon’s breath ghosts over his ear, sends a shiver down
Jimin’s spine, low moan escaping him as Namjoon starts stroking his cock. It’s
too dry, even with the added wetness of Jimin’s precum.
“N-nothing,” Jimin gasps, head falling against Namjoon’s shoulder and he
doesn’t have to tell Namjoon it’s not wet enough. Namjoon spits into his hand
to slick Jimin up, stroking him slowly. His other hand slips up Jimin’s shirt,
smooths over Jimin’s spine until it traces back down, big hand cupping Jimin’s
ass.
“You always look hot,” Namjoon says, voice falling against Jimin’s ear, deep
and husky. Jimin lets out a whine, hips bucking up into Namjoon’s hand. “But I
like it when you’re cute just for me.”
“O-oh,” Jimin moans, helplessly digging his face into Namjoon’s neck. Namjoon’s
skin is salty, cool to the touch. His heart skips a beat, then another, body
shuddering as Namjoon picks up speed, hand gripping Jimin’s ass firmly.
“You know,” Namjoon tells him, thumb dragging over Jimin’s slit, digging into
the sensitive flesh under his cock head. “You look especially cute when you’re
all fucked out, lying on my bed, near tears. Think I’m gonna have to show you
next time.”
“Hyung,” Jimin whines, flushing at the image that flashes through his mind,
mouth falling open as Namjoon flicks his wrist on the upstroke. He’s got a firm
grip around Jimin’s cock, fingers kneading into Jimin’s ass and it shoots
little sparks up his spine, tingling under Jimin’s skin.
“But you’re definitely cutest when you’re hiccuping my name, bouncing on my
cock, all flushed because you’re embarrassed. I’m getting hard just thinking
about it,” Namjoon whispers to him. Jimin’s breath catches in his throat, moan
so loud it fills the entire room, reverberating back to him. He can feel his
ass clench up, balls tightening as Namjoon lets him fuck into his hand, hips
thrusting upwards.
“Gonna, gonna come, hyung,” Jimin pants, fingers digging into Namjoon’s
shoulder and back. Namjoon twists his hand into Jimin’s hair, pulls him away
from Namjoon’s neck before kissing him, tongue sweeping into Jimin’s mouth.
Jimin nearly mewls, crying out Namjoon’s name as he comes, toes curling, body
singing.
“Now that was hot,” Namjoon grins, Jimin groaning as he falls against him once
more, body going limp as he recovers. Namjoon wipes his hand clean, his
discarded tissues coming in handy. He’s even so nice as to tuck Jimin back in,
fix up his pants and Jimin sighs at the fingers massaging into his neck. “You
good?”
“My detention’s over,” Jimin mumbles, eyes landing on the clock in the back of
the classroom. He pushes off of Namjoon, smoothes out Namjoon’s collar before
looking him in the eye.
“And what did you learn from your detention, Jimin?” Namjoon asks, his dimple
showing as he eyes Jimin. He gets off of Namjoon, stretching his arms out,
sighing when he lets them fall back down. Namjoon’s still sitting, staring at
Jimin, hands reaching to tuck Jimin’s shirt back into his pants. They still had
to go home.
“That I give really good head,” Jimin answers, laughing when Namjoon slaps his
thigh, scowl carrying his dimple away.
“Brat,” Namjoon says, standing up himself. He kisses Jimin once, before
grabbing his hand and pulling him out of the room. “You need a couple more
detentions, huh.”
“I think I can handle them.”
