Namjoon never thinks about why he slaps his face so often. When asked, he just says he likes it, and he doesn't dig any deeper. He likes being touched. He's not being touched enough. His hands feel big against his cheeks. It's comforting.

He likes it and he doesn't question it.

Namjoon never thinks about why Jungkook spanks people so often. Jungkook slaps his ass when he walk past and he laughs to tears when they use it as punishment in shows. Jungkook slaps your ass when he's happy and Namjoon likes him happy.

He doesn't question this either.

(1)

The first time Namjoon thinks about it, his face is pressed in the crook of Jungkook's neck and he's trying to stifle his laughter. Jungkook's bratty, self-satisfied grin turns to small whines when he realizes he can feel Namjoon's body shaking with laughter inside his ass.

"Hyung" he complains, pouting easily because he thinks it'll get him what he wants.

It does usually, but Namjoon is still laughing, and Jungkook's sudden change of behavior only makes him laugh harder.

"Hyung, move. Mooove."

"No," Namjoon says, rubbing his nose against Jungkook's collarbone. "Why would you cockblock a goose in the first place?"

"I didn't mean- it just-" Jungkook is growing restless, squirming under him and around him. His legs tighten around his waist to try to make him move.

He succeeds into pushing Namjoon deeper inside and Namjoon chokes on his laughter at the feeling of his ass clenching down around him, but then Jungkook whines because he can't move him back on his own and Namjoon is laughing again.

"I-I like it better when you're laughing on m-my dick," Jungkook complains, which is a fat lie - he gets as overwhelmed when Namjoon is laughing under him.

"Serves you well for talking about geese in the middle of sex."

"Hyung!" Jungkook protests, squirming.

He reaches behind Namjoon and gives a sharp slap on his backside. "Hyung, move!"

Namjoon's laughter stops at once. He freezes, trying to process the sting on his bare ass as it spreads and dissipates on his skin.

It's warm. Jungkook's hand is bigger than he remembers it being.

Namjoon takes a few seconds and Jungkook grows restless under him.

"Hyung," he whines again, voice wet.

Namjoon rumbles low in his throat and he lets his hands slide down to grip Jungkook's waist.

"Yeah," he says, voice hoarse and unamused. "I got you baby."

He fucks Jungkook harder than the situation calls for, but Jungkook is into it and Namjoon keeps feeling the ghost his hand on his ass, prompting him to go faster.

Now he's thinking about it. Now he can't stop thinking about it.

(2)

The second time Namjoon thinks about it, the positions are reversed.

His face is buried in Jungkook's pillow, and it smells fresh and clean like everything Jungkook owns. Jungkook is pouting this time too, because Namjoon just told him to wear a condom.

Namjoon turns his head away from the pillow, glancing above his shoulder.

"Too tired to clean up afterwards," he says, watching his boyfriend rip a condom open with more force than needed.

"I'd clean you out," Jungkook argues.

"Eating your cum out of my ass isn't cleaning."

Jungkook rolls the condom down on his cock and mutters, "I brushed my teeth. Your ass would smell like mint."

Namjoon turns his head back around to laugh in the pillow.

"I'll fart in your face," he threatens, smile hidden from view.

"Hyung!" Jungkook protests, and punctuates it with a loud slap on his ass.

It stings. All the hahas die on his tongue, the hit strong enough to make him flinch, knees slipping wider apart on the mattress. He has the urge to rub at his ass to ease the blow. His cock twitches.

Jungkook is blissfully unaware, busy lubing himself up and mumbling something to himself. He feels him scoot closer, pressing the head of his cock against his hole before pushing in with a pretty moan, but all Namjoon can think about is the sound of Jungkook's hand striking him.

He feels the whole length of Jungkook's dick inside him, feels his hips press against his ass and he tries to hang onto the sting that was there, disappearing all too quickly. He wants it again. He wants it harder. He wants to feel it burn hotter than his arousal.

His knees slide even wider apart and Jungkook has to hoist him back up, hands on his waist pulling him back on his cock and they both moan. Jungkook is strong - he's so strong, it could hurt so much, it could hurt so good.

"Shit," Namjoon curses. "Do it again."

"U-uh?" Jungkook is confused but he's obedient and he immediately yanks him back on his dick, trying to repeat his earlier movement.

Namjoon moans, arching his back.

"It's good but not- not this, shit--" To hell with it. "Hit me."

"H-hit you?" Jungkook's hips falter, which is everything Namjoon doesn't want - he'd set a nice pace, nailing his prostate every thrust and Namjoon can only groan with disappointment when he stills. "I'd never hit you."

"My ass. You slapped it."

"Uh."

"Do it again."

Jungkook doesn't answer or move and Namjoon turns his head around to find him red-faced.

"You mean- like-"

"Yeah, like that."

"Oh." Jungkook looks down and gives a very gentle slap on his right cheek, more of a shy pat. "This?"

"Yeah. Harder baby, you can- oh fuck-"

Jungkook strikes him one more time, harder, effectively cutting his words. He curls on himself and clenches on Jungkook's dick, and Jungkook moans and bucks up into him in return.

It's not hard enough for the pain to blind him, for the sting to last and warm his skin, but Jungkook's hand is big and soft and warm when it hesitantly strikes him a third time.

"Yes, baby, yes," Namjoon hisses, pressing his ass back towards Jungkook, pushing him deeper inside.

Jungkook only manages a few hits before he's burying his face between his shoulder blades, whining.

"Hyung," he says, voice breathy and high-pitched. "Oh my God hyung."

His arms wrap around his waist, squeezing him as he pants and visibly tries not to get overwhelmed.

This was bound to happen - Namjoon is wound too tight, clenching too hard on Jungkook's cock in anticipation and pleasure, and his boyfriend always does get worked up way too easily.

"It's ok," Namjoon says, reaching back to grab on Jungkook's thighs. "Fuck me hard baby."

Neither of them last very long, and Namjoon spills inside his own fist, thinking about Jungkook's hand, thinking about Jungkook giving it to him harder, thinking about taking until he can't take it anymore.

He thinks about spanking.

God he's thinking about spanking.

The third time, Namjoon doesn't just think about it.

They're sitting cross-legged on Jungkook's bed and Jungkook already has a semi that he's failing at hiding from him.

"So," Namjoon says, politely averting his eyes not to embarrass him further. "It's really ok for you?"

Jungkook nods, determined frown on his face at odds with the redness of his ears.

"Yes."

"You're not doing this just to make me happy?"

"No," and more quietly, "I want to do it too."

"How hard can you hit me?" He asks.

"As hard as I want to," Jungkook recites.

"And when do you stop?"

"When you tell me to stop or when I don't want to do it anymore."

Namjoon nods. "Good. Now sit against the headboard."

Jungkook obeys quickly, scooting back until he's leaning against the headboard, hands in his lap and looking up at him expectantly.

Namjoon gets up from the bed, quickly stripping off his clothes until he stands naked as the day he was born.

Jungkook stares. He stares back.

"Right."

He climbs back up on the bed, and Jungkook helpfully lift his hands from his lap to let him lay on him, ass propped up on his thighs. This is more embarrassing than expected, but Jungkook makes a little noise in the back of his throat and Namjoon relaxes.

His hands come down to gently pet at him, caressing down his thighs and squeezing his buttocks.

"When do I start?" he asks.

Namjoon presses his face in the sheets and pushes his ass back against Jungkook's hand.

"Whenever you want baby."

Jungkook paws at his ass a bit more, muscles tense and palms clammy like he's the one bracing himself for the impact.

"Breathe baby," Namjoon whispers and he knows Jungkook is nodding even if he can't see him.

The first strike is mild, gentle and tentative, and Namjoon melts in Jungkook's lap. He stretches out his legs, at ease in his current position.

"That's alright?" Jungkook asks, slightly anxious.

"Yeah, keep going."

His hand comes down a second time, still hesitant but bolder, and it jostles his body. Jungkook warms up, hitting him several times, slowly, gauging his reaction, and Namjoon plays it up a bit, sighing pleasantly to encourage him.

His hand feels nice, warm and a bit unsure but there's power there and Namjoom can't wait for Jungkook to unleash it. He wants to tell him to go harder but he waits, lets him grow comfortable.

After a dozen hits Namjoon's ass does feel warmer, more sensitive to the hits.

He can feel Jungkook easing up, shifting under him and his boner presses into his hips. Namjoon holds back a laughter, his own dick fattening up against Jungkook's thigh.

"Can I-"

"You can go harder Kookie it's alright."

He doesn't brace himself for the next strike and it takes him by surprise. He yelps, body jerking and buttocks tensing at the sharp sting. It diffuses immediately, spreading warmth through his skin and this, this is what Namjoon is looking for for.

He relaxes as fast as he'd tensed up, thrilled at the way the sting won't quite leave yet and he feels the urge to rub his ass to soothe it.

Jungkook does it again, a second slap at the exact same spot that has Namjoon's body jerking.

"Yes," he hisses, feeling the pain blossom.

"Is this alright?" Jungkook asks, and he sounds breathless already, as affected as Namjoon feels.

"Yeah this is- ah fuck," he breaks out in a pained moan when Jungkook's hand comes down a third time, always at the same spot. He tenses again, ass throbbing and cock twitching.

Harder, he thinks. He knows Jungkook can go harder. He remembers Jungkook spanking Hoseok as punishment after one of their games, and Hoseok had felt it the rest of the day whenever he sat down, and Namjoon wants that. He wants that, wants to feel nothing but that.

Jungkook grows more confident with every hit, doesn't give him as much time between each strikes and Namjoon is fully hard now, rubbing against Jungkook's thigh every time his body jerks upward.

The sound of Jungkook's hand slapping his skin, loud as a whip, only edges him more.

It's all he can hear, above his own painting and choked moans. Jungkook barely seems to be breathing at all, left hand still clammy on his back.

His ass hurts and the ache never passes, only grows stronger and more persistent with every hits.

Jungkook is only striking his right cheek, again and again, and Namjoon takes it as long as he can before his back bows and his body jerks away from Jungkook's hand to avoid being hit again.

Jungkook stops immediately and Namjoon pants, thrilled by his own reactions.

It's an instinct he figures, to try and get away from the pain, but Namjoon wants to be pushed past his limits.

"It's ok," he chokes out before Jungkook can freak out. "K-keep going."

"Is this alright?" Jungkook asks. "Am I doing alright?"

Namjoon turns his head to peek at Jungkook's face, finds him flushed and distraught, searching for his eyes.

"Is this too much for you baby?"

Jungkook shakes his head. "No I want to do it more. It's just- a lot."

Namjoon smiles at him before nuzzling back into the soft sheets. "Give it your all Jungkook, I promise I can take it."

At least he thinks he can take it. Jungkook whines at his words and his hand rains down, so hard Namjoon scratches at the sheets, twisting sideways.

He moans, deep and unabashed and his dick hurts as much as his ass does. He settles back properly in Jungkook's lap, gripping the sheets and panting. His ass stings and the pain has long since stopped lingering, anchored in his flesh and blossoming all over his lower half.

"More," he chokes out. "A-again, fuck."

Jungkook obeys, dealing a few more strikes that have Namjoon's eyes burning with tears. He moans, pained 'ah's at each of Jungkook's hits, body tight and tense, more vulnerable than he ever remembers being.

He takes it as much as he can before reaching his threshold and he gasps, pushing back on his knees so Jungkook can't spank him again. He rests his head on his arms to catch his breathe, trembling with the effort not to rub at his sore ass.

Jungkook caresses his thighs, waiting for instructions. He reaches up, fondling Namjoon's balls a bit and that has Namjoon arching his back, sharp pleasure mixing with the pain. He takes a few seconds before flattening himself back down, letting out a shaky exhale.

Jungkook tenses ever so slightly at the friction when Namjoon arranges himself on his lap again, clothed boner against his hip.

"Is this really ok?" He asks.

"It hurts," Namjoon says. "I can't keep my body from reacting to the pain but it's good. You're doing great."

He looks back just in time to see the delighted smile on Jungkook's pink face at the praise.

He touches him again, gentle fingers on his ass and balls that have him melting on the mattress.

"Your ass is so pink," Jungkook mumbles, awed, and Namjoon knows to brace himself when he can't feel his hands playing with his balls anymore.

Nothing prepares him for the rapid fire succession of hits, precise and unrelenting, and he can only shout and squirm.

"Hyung," that's Jungkook's flustered voice above the echoes of spanking. "You're so so pink hyung."

Namjoon moans, legs twitching and dick throbbing with pain and pleasure alike.

Jungkook pauses, giving them both time to gather themselves, but it doesn't make the pain go away in the slightest. He feels his damn heartbeat in his ass, the skin burning hot, and it hurts. It hurts so much and Namjoon think he could come just from this.

He ruts against Jungkook's thigh a few times to get some relief, lets pleasure silence the pain for just a few seconds.

"More Koo, more." He moans, and he reaches behind himself for Jungkook's hand, guiding it down to his thighs. "Here."

Jungkook whines, high and needy, and kneads at his thighs. His palm is hot, probably so sore from spanking him but Jungkook doesn't seem to mind. He draws his hand back and slaps his thighs and - fuck, they're definitely more sensitive than his ass.

He whimpers, writhing as Jungkook strikes one thigh then the other, several times in a row. He jerks and twists in Jungkook's lap, curses at the delicious sting that spreads in the back of his thighs.

His ass is still painful and this keeps getting worse, keeps getting better.

"Fuck." He kicks his legs and parts them and closes them again, body trying so hard to get away from what's hurting it. "Fuck, fuck, fuck," he curses and finally feels tears rolling down his cheeks.

He rubs against Jungkook's leg whenever he pauses, desperate for relief.

He's in pain but he's also painfully hard. He only needs a bit more, a bit more of that helplessness, a bit more of this raw fire and of those whipping sounds that make his body seize up as much as the feeling of them.

"Oh hyung," Jungkook sounds pained the way he does when he feels too much and wants too hard. "Hyung it's so- it's so dirty you're-"

He doesn't finish his sentence, hand coming down to abuse his thighs again, unconsciously pressing down on his back to keep him still.

Namjoon bites the sheets, a wave of pleasure washing over him at that, even if Jungkook doesn't seem to realize what he did. He cries and moans in the bedsheets, wetting it with saliva.

Jungkook keeps going until the cloth slips from Namjoon's mouth and he's sobbing out loud.

"Hyung?"

"God," Namjoon cries, voice scratching his throat. "It's so good- ah!"

He yelps but manages to keep himself mostly still as the hits keep coming.

"You're so red hyung," Jungkook sounds even needier now. "You're so red oh my God."

Namjoon sobs and hopes it counts as acknoledgement. He bets he's red. God the sight that must be, he's going to feel it for days.

He endures it until he can't anymore, body caving in. He reaches back again, stilling Jungkook's hand before it can strike down again.

He pants, exhales coming out high pitched and so, so sore he doesn't think he'll ever stop feeling it. His cock is leaking precum on Jungkook's pants.

Jungkook's hand is lax in his grip, waiting for Namjoon to guide him again.

Jungkook won't do anything he doesn't tell him to do, and isn't that the sweetest of things. It makes Namjoon want him to go harder, overwhelmed with the desire to give himself whole to the boy who'd already offered him everything he had.

H-higher," he says, bringing Jungkook's hand back to his ass.

Jungkook makes a small noise in the back of his throat and then he's spanking him again. Namjoon sobs, squirming, trying to find relief in the harsh press of his dick against Jungkook's pants.

His ass is still too sore and the pain of Jungkook's quick strikes is almost unbearable. His hits aren't as powerful now, worn down by the effort of spanking him, but his ass is so sensitive that it doesn't matter. Namjoon takes all that Jungkook dishes out, crying and squirming.

His cock is squeezed, squished harder against Jungkook with every strikes that jerks Namjoon's body. It should feel bad but it's nothing compared to the sensation of his ass burning with pain.

Hot pleasure meets burning pain, mixing until he can't distinguish one from the other.

He feels his orgasm build up with every strikes, vivid sparks that shoots up his spine and down his cock.

He grinds down as best as he can, biting the sheets and taking it, taking it, taking it again until his vision blanks and white pleasure seizes him.

He spills against Jungkook's thigh, scream muffled in the sheets and hips rutting desperately. Jungkook hands out a few more strikes, jerking his body against him until he's rode out the last of his orgasm. Namjoon twists sideways when it becomes too much and Jungkook stops.

"Hyung, did you-"

"Yeah."

"Just from-"

"Yeah."

"Oh my God," Jungkook sounds almost pained, hands coming down to rub his ass gently, but even that touch is too much, too harsh for him. He tenses up and Jungkook jerks his hands back.

"You're so red hyung. I- I think it's turning purple? It's so pretty hyung."

"Yeah? I'll look at it later. There's still one thing-" he paws at Jungkook until he can find his stomach, then slide down to his crotch.

Jungkook freezes up and moans.

Namjoon slips his hand in Jungkook's underwear, palming at his cock.

"You're so wet baby," he says, drawing a moan from his boyfriend. "Did you get so hard just from spanking your hyung mm? Did you like it?"

"Y-yes," Jungkook stutters, voice shaky. "Yes, yes."

It doesn't take long to bring Jungkook over the edge, worked up as he is, and soon enough he's coming in his hand, gasping oh so prettily above him.

Namjoon pulls his hand out when Jungkook grows soft in his fist, bringing his fingerd to his mouth to lick them clean.

When he's done he flips over onto his back, then promptly flips onto his stomach again.

"Fuck," he hisses, ass throbbing with renewed pain.

"Hurts?" Jungkook asks, voice still breathy. "Wait, wait-"

He scrambles off the bed and to the bathroom, coming back with soothing cream.

He kneels by his side and starts gently applying the cold ointment to his reddened butt, and the effect is immediate. Namjoon finds himself melting as the pain diminishes, numbed by the cold. Jungkook is careful, covering all the abused skin with a thick layer of the cream.

When he's done he wipes his hands on his own pants.

"Give me your hand," Namjoon says, and Jungkook lets him grab his right hand, bringing it to his eyes.

As expected, his palm is bright red.

Namjoon pressed a few wet kisses against it to soothe the pain. "My poor baby."

He tugs and Jungkook follows, willingly lying down next to him.

"This was pretty hot," Namjoon says and Jungkook nods eagerly.

"It was."

"I'm never sitting up again though."

Jungkook laughs mirthfully. "I'll carry you. Bridal style."

Namjoon makes a face. "No thanks. I lost my ass, not my dignity."

Jungkook laughs again, all soft and open. Namjoon feels warm, maybe a bit too much still, but he finds comfort in it, finds strength in the knowledge he pushed past his limits.

Namjoon still doesn't think about why he slaps his own face so often. When asked about it, he just says he likes it.

There, all done. Hopefully I did newly awoken pain slut Namjoon justice. Here's the start of the thread.
