Curiosity killed the cat

Summary:

Sunghoon has a problem - he decides - when he realises he cant keep his eyes off his bandmates crotch. Not in a gay way or anything, he's not like that - not that it's bad! Its just... he's not gay. It's just curiosity...

Or;

Sunghoon develops morbid curiosity over what's really inside his bandmates pants. Sunoo answers his question in the most immersive way possible.

Notes:

Okay its actually gnawing away at my mind that the timeline (in my own fic!) doesnt even make sense bc realistically they stopped being styled in skinny jeans in like 2022 lol. You can decide what era this is in - or don't - smut doesn't have to make sense.

And if you notice the tenses change a lot, it's bc i suck at writing. Sorry. Ignore it for my sake.

(See the end of the work for more notes.)

Work Text:

Sunghoon has a problem - he decides - when he realises he cant keep his eyes of his bandmate's crotch. Not in a gay way or anything, he's not like that - not that it's bad to be gay! Its just... he's not gay. It's just pure, morbid curiousity.

It starts innocently enough.

Sunghoon notices it first during a fitting session when the stylists squeezed Sunoo into those impossibly tight pants that hugged his legs like a second skin. He's not actively seeking it or anything! His eyes just naturally move there, and he knows it sounds like a lot of excuses, but it's kinda hard to miss. He notices the fabric bunched up in that area, stretched so taut it should have revealed something - a bulge, a dent, anything. But there was nothing. Just smooth, seamless lines. And those hips, wide and curvaceous, almost like he was wearing hip pads. Sunghoon had never seen anything like it, unless he missed a biology class in high school.

He also notices that he's seen every member naked (naturally it happens when living together. You get too comfortable and mistakes happen.) but Sunoo. Always secretive in changing, never seeing more than the waistband of his underwear in accidental slip-ups. None of the members seem to talk about it, or point it out and it leaves him feeling like a creep - and fair enough, maybe he is. Jeez, a guy can't be curious these days? And, hey - for what it's worth - if he doesn't have a penis, then technically, it wouldn't make him gay. Damn it. He thinks to himself as Sunoo makes his way through the kitchen.

 

 

It was their off day, the kind where the members lounged around the dorm doing absolutely nothing productive. Sunoo comes down fashionably late for "breakfast" at 1:30 PM, flashing a bright smile and chirping, "Good morning, hyung!" He pours himself a bowl of cereal, humming softly under his breath, and to Sunghoon's dismay, plops down right next to him at the table. The pyjama shorts Sunoo wore were criminally short, riding up his thighs as he settled in.

When he sat, those plush, pink thighs spread out, spilling over the edges of the seat like soft dough. The shorts hiked up even further, the fabric tightening into a sharp "V" shape around his crotch. He's look again - it was impossible not to, damn it. It's driving him nuts that he seems to be the only person with this on his mind. Why was he the only one obsessing over this? Here was this pretty boy with pretty thighs and probably a pretty pink- wait, what? He's only curious, not interested - in Sunoo that is.

Perhaps he should've been interested as lost in his thoughts, Sunghoon has barely registered that five minutes had passed. Sunoo had been chattering away about some funny fan interaction from their last live stream, his voice animated and eager. Now, he was staring at Sunghoon with those big, doe-like eyes, seemingly waiting for an opinion. But Sunghoon had zoned out completely, his mind elsewhere.

From Sunoo's perspective, Sunghoon had been acting weird around him for days - like weirder than normal Sunghoon weird. Constantly spacing out on god-knows-what (well we all know what), not listening to a single word he says, and stumbling over responses like he was allergic to conversation. It must have felt like rejection, like Sunoo's chatter was just annoying him. To an outsider, it was obvious that Sunghoon wasn't invested at all.

"Nevermind," Sunoo mutters, the light fading from his face as he turns back to his cereal, stirring it absently with his spoon.

Sunghoon's chest tightens with guilt and he wants to say something so bad and if his stupid mouth would just work-

As Sunoo finished up, he dumps his bowl in the sink with a clatter and hurries back to his room. Sunghoon's gaze follows him - not his ass, okay? Just... watching him walk away. He reckons he should apologise eventually, it probably looks like Sunghoon hates Sunoo but he's just - occupied - it's really far from the truth.

 

 

Nonetheless, the day moves on without Sunghoon saying a word to Sunoo, even after promising to himself that he would apologise or attempt to clear things up. The guilt is eating him alive and this new obsession, curiousity, conspiracy theory thing is slowly eating away at his relationship with Sunoo.

 

 

It's half past nine when Sunghoon comes knocking on Sunoo's door, finally mustering up the courage to speak to him - as long as his dirty conscience doesn't get in the way.

"Yes?" Sunoo calls out before Sunghoon semi-invites himself in. He doesnt move much, not 'making himself at home' as they say, just carefully stands at the door fidgeting with his hands like a kid that's about to tell their parents they've just thrown up in the middle of the night.

Sunoo was lounging under the covers, scrolling on his phone, his room dimly lit by a bedside lamp. He looked up as the door clicked shut. "Oh, hyung. What are you doing here?"

And suddenly, Sunghoon isn't even sure himself. He can't speak to Sunoo in this state - he'd just ruin everything again. Sunghoon isn't good at speaking to Sunoo, not that they aren't close these days, thats the exact problem. Controlling himself around Sunoo is hard; he always blurted out the most ridiculous things, scaring him off. Sunoo was a saint for putting up with it, always responding with patience and respect. So, he doesn't face the problem head-on, surely he can fix the tension by having a casual conversation with him out of his own free will - show Sunoo he's actually interested in what he has to say.

"Uhh..skincare," He thinks up on the spot, knowing Sunoo takes heavy interest in it. "I wanted to take better care of my skin and obviously you're the expert so I uh... wanted some advice. You know, like,  what you use and stuff." His voice shook and he fiddled with the hem of his shirt to steady himself.

"Oh okay, well come sit down then. Why are you standing awkwardly at the door? Do I need to invite you in? You’re taking the vampire concept a bit too seriously." He chuckles lightly, tossing off the covers and swinging his legs over the side of the bed. He rummages through his drawer, pulling out an array of bottles and tubes.

Sunghoon is perched on the far edge of the bed - keeping a notably awkward distance, probably for the best. Sunoo sat nearby, products piled in his lap, and began explaining his routine with enthusiasm. He demonstrated each step, holding up a cleanser to show how he massaged it in, then a toner for hydration.

But honestly, Sunghoon had done it again. He wasn't listening to a word. Those impossibly short, impossibly tight pyjama shorts were back in view, Sunoo's thighs plumping up as he shifted, his legs slightly parted. The fabric rolled up at the edges, leaving little to the imagination - except for the obvious. Sunghoon's mind raced. The way the shorts clung, the smooth curve where there should be... something.

"Hyung, what are you looking at?" Sunoo's voice cut through, snapping Sunghoon out of his trance. "You're always zoning out when I'm talking to you!" He whines, pouting those unbelievably glossy lips. Wow, were they always like that? They look perfect for sucking d-

"Hyung!" Sunoo exclaims again, waving a hand in front of his face.

"Sorry, I wanted to uh... look at the ingredients," Sunghoon stammers, his cool factor evaporating.

"Okay...." Sunoo sounded unconvinced but handed over the moisturizer anyway, continuing his explanation while Sunghoon pretended to care about dimethicone, niacinamide, hyaluronic acid.

As Sunoo wrapped up, he carefully arranged his products back in the drawer, organizing them with neat precision before crawling back under the covers and picking up his phone. Sunghoon's hand was on the doorknob, ready to leave, but something rooted him in place. He couldn't leave yet.

"Do you have a spare phone charger I can borrow?" he improvised, turning back with forced casualness.

"Oh, yeah. It's in the second drawer," Sunoo said, pointing to the dresser on the far left.

There's 4 drawers, and Sunghoon should probably ask which one in specific he means, but he opens the one second from the bottom amyway.

Immediate regret creeps through Sunghoons veins upon opening the drawer. Curiousity really killed the cat, huh. (i did it i said the thing). He's met with several pairs of women's underwear with "Calvin Klein" lettering embellishing the waistband. He slamms the dresser too fast and it makes a loud 'thud!' noise. His heart hammering, he slowly turns to face Sunoo and miraculously he didnt hear the loud noise or decided not to pay attention. Either way, he quickly retrieves the charger from the second drawer from the top before announcing his departure, robotic and overly cheery. "Found it! On my way out now!" He exclaims.

Sunoo just smiled and nodded, but Sunghoon could feel his own tension radiating with his stiff posture, forced grin. He made it to the door with stealthy steps, but he couldn't leave after that. He wasn't a perv. He was just... an observationalist. Anyone could've made that mistake. He's gonna ask about it. Really. Get it off his chest and then speaking to Sunoo will be normal again. Unless it makes it worse. Oh god, what if he ruined it again?

"What are you still doing in my room?" Sunghoon's train of thought is cut off once again with the direct question.

'It's now or never' he thinks to himself - then he thinks that was corny, then he thinks that was stupid, then he thinks this is mistake, then he thinks he should leave, then thinks with his penis (sorry, no, his heart) and makes his way back to the edge of Sunoo's bed, discarding the charger and the moisturiser Sunoo recommended him on his dressing table.

"I- uh, have a question." He stammers, his voice barely above a whisper.

"Okay..." he says, placing his phone down, his tone a mix of half-confusion and half-weirded-the-fuck-out.

"It's about..." he starts but doesnt continue, looking about the place, regretting opening his mouth already.

"...about?"

Fuck it. Sunghoon's already embarrased himself in front of Sunoo on multiple occasions. "Um...masturbation," he says, tone still shaky and unconfident, heat rising in his cheeks.

Sunoo freezes. Top 10 worst rizz moments - nice one, Sunghoon.

"Sorry? You want to ask me about masturbation?" He asks rather dumbfounded. This is the type of over-the-top personal, uncomfortable, invasive question you'd normally expect Sunghoon to ask someone like Jake.

He backpedalled fast. "It's not like weird or anything! I asked Jake too. I uh.... I was just wondering like, you know, with our hectic schedules and stuff.. do you..." he once again regrets letting the immature, reckless, Sunoo-branded part of his brain take over.

"...do I masturbate?" Sunoo finishes his sentence for him, arching an eyebrow.

"Uh, yes," he stammers before continuing, "I'm just taking, like, quantitive data. Jake said yes too. Not that you were wondering or needed to know or...sorry".

Sunoo stared for a beat, then burst out laughing, a light sound that eased the tension slightly. "I do, I guess? Is that really what you wanted to ask me?"

"Yes, that's all," Sunghoon rushed out, scrambling to grab his things and head for the door. But as his fingers brushed the knob, the answer didn't satisfy him. It only fueled the fire. He made a U-turn and sat down again. "I have another question."

"This guy is a weirdo" - Sunoo, probably. Sunghoon's realising the problem with every word that comes out of his mouth in real time, but with the effect Sunoo has on Sunghoon, they keep tumbling out like word vomit.

"Okay." Is all Sunoo says but Sunghoon is pretty sure he is thoroughly weirded out and uncomfortable by this point.

"I- uh- how do you um... do it. You know, it." his leg is bouncing frantically by this point and his hands are clammy as he twists his fingers together, avoiding eye contact.

"Did you ask Jake this too?"

And Sunghoon's finding it harder and harder to keep his composure (if theres any of it left). Sunoo seems offended now, his eyes narrowing, but Sunghoon doesnt say anything - just stares at him like an idiot.

"Well, like, most people do I guess?" he continues, his voice edged with discomfort.

Sunghoon keeps staring at Sunoo, then down between his legs, then up at Sunoo again before clearing his throat and nodding weakly.

"I have a feeling you're not satisfied with my answer.." Sunoo says, pursing his lips.

He should probably stop speaking and leav-

"Well, um- I mean surely you don't do it like us, like you're. Um." He whispers the last part, leaning in closer. "You're not like us, are you?" And Sunoo looks at him slightly maddened by the homophobic undertones of his question.

"You mean straight?" He asks sharply.

"Sure."

"Well gay people can do it like that as well.."

"But how?"

Sunoo is seriously offended by this point, his voice rising in frustration "The same way you guys do!" He knows he's not wrong in what he's asking but his words are coming out all twisted. "No, like, but how?" He pressed.

"Sunghoon, do you masturbaute?" Sunoo redirected, his voice a little softer, trying to regain control.

"Uh, yes..." he stammers, caught off guard

"So what's your question then?" Sunoo is staring him head-on but his pending hard-on is causing his brain to malfunction and he can't help but look down.

"Uh, I'm sorry,,I don't know. I should leave. I'm sorry..." but before he can properly get up Sunoo holds his arm, pushing him back down to sit on the bed.

"I can show you. If you want," Sunoo said, his voice faltering just a bit, but his eyes locked confidently onto Sunghoon's.

Sunghoon doesn't answer, frozen in place. Sunoo trails his hands down from Sunghoon's arm to his wrist, guiding him gently but deliberately. He shifts to kneel on the bed, legs slightly spread, and brought Sunghoon's fingers to his crotch, pressing them against the warm, smooth fabric. He moved Sunghoon's hand up and down in slow, teasing strokes, the touch electric.

Well, Sunghoon has his answer - in the most delightful way possible. There was no bulge, just soft, yielding warmth. A rush of heat flooded him.

"Fuck, Sunoo..." he breaths out, his voice husky with surprise and desire.

Sunoo giggles, and it sends shivers down Sunghoon's spine. He releases Sunghoon's hand and leans back on his arms, thighs parting invitingly. "Do you want to touch me, hyung?"

Sunghoon's jaw hung open, entranced, before Sunoo's words snapped him back. "I uh- I've never..." He trails off, staring at his lap, cheeks burning with embarrassment.

"Are you a virgin?" Sunoo asks innocently, tilting his head and pouting - not entirely mocking, but with a teasing edge that made Sunghoon squirm.

Sunghoon didn't respond, opting to stare at the wall instead. He could feel the flush spreading across his face, hot and humiliating. Sunoo crawls closer, grabbing Sunghoon's chin and turning his face back. He scans him up and down with sultry eyes, then purrs in his ear, "It's okay. I can teach you."

Sunoo shifts from his hands and knees to a more comfortable position, leaning back with his hands braced behind him. He peels off his shorts and underwear agonizingly slow, never breaking eye contact - each inch of fabric sliding down his thighs like a deliberate tease, revealing smooth, flushed skin.

Now fully exposed, Sunoo spread his legs wider, his pussy glistening in the low light. Sunghoon was absolutely frozen, breath caught in his throat. Sunoo wet his fingers with his mouth, sucking on them sensually - tongue swirling, lips parting with a soft pop - before trailing them down his body. He explained calmly at first, voice steady. "I start like this, hyung, teasing the outside, building it up slow." His fingers circled his clit, then dipped inside his hole, movements deliberate and instructional.

But as he picked up the pace, words dissolved into obscene moans - loud, unrestrained, echoing in the room. His hips bucked subtly, fingers thrusting deeper, slick sounds filling the air. Sunghoon sat rigid on the edge of the bed, his own erection throbbing painfully in his sweatpants. He rubbed his thigh restlessly, inching close to palming himself but holding back, mesmerized as Sunoo fucked himself on his fingers. "Mhn, hyung~ Feels so good..."

Sunoo pulled out suddenly, leaving them both panting in disappointment. He brought Sunghoon back to reality with a sly grin. "Are you going to touch yourself, or do you want me to show you how to do that too?"

Sunghoon said nothing, too stunned. Sunoo crawled over, confident and predatory, yanking Sunghoon's pants and boxers down just enough for his cock to spring free - hard, flushed, and leaking at the tip. Sunoo looks up with those intoxicating hazel eyes, pouting dramatically. "You're so big, hyung. How are you supposed to fit inside of me?"

"What?" Sunghoon's first coherent words since this started.

Sunoo's pout deepened, feigning offense. "You don't want to fuck me?" He tilts his head, batting his lashes.

Sunghoon shook his head furiously - what a ridiculous question. Who wouldn't? "No, no, no - I do, I do."

Sunoo grinned triumphantly and sank his mouth onto Sunghoon's cock without warning, engulfing the length in wet heat. He pulled back slowly, tongue lapping stripes along the shaft, kissing the tip before descending again. His hand stroked what his mouth couldn't reach, twisting rhythmically. Sunoo's mouth was magic. Tongue encircling, head bobbing with perfect suction. Sunghoon has never had a blowjob before, but this? This had to be the best any man could receive. Sunoo's back arched, shirt riding up to expose his ass, which shook enticingly with every movement and, god, it was too much. "Sunoo, I'm close."

Sunoo released him with a wet pop, pushing him flat on his back. "Not yet," he commands, crawling onto Sunghoon's lap.

Sunghoon's hands instinctively grip Sunoo's impossibly small waist, kneading the soft, warm flesh there. Sunoo lifted off his shirt, the last barrier, revealing milky skin flushed red from arousal, nipples hardening in the cool air.

He rose on his knees, grasping Sunghoon's cock and slapping it against his pussy a few times with wet, teasing smacks that made Sunghoon groan. He dragged it up and down his slick folds, coating it before sinking down slowly. They sigh in unison as he bottoms out, Sunoo's walls clenching tight around him.

"Fuck, Sunoo. You're so tight - I could come right now." Sunghoon's voice was strained, hips twitching upward involuntarily.

Sunoo leans down, hands on Sunghoon's chest for balance. "You do that, but just know, I'm not stopping until I come." He rolls his hips backward in a slow, grinding motion, craning his neck to watch his own ass bounce. Sunghoon's hands slid down to knead the plump flesh, squeezing as Sunoo picked up speed.

"Fuck, I can feel you so deep in my cunt." Sunoo moans, hands trailing further down Sunghoon's torso for leverage as he sat up straighter.

Sunghoon unraveled into a mess of groans and whimpers, overwhelmed as Sunoo rode him with abandon. "Sunoo, I'm coming," he gasps, clutching Sunoo's arms.

Sunoo lifts off, bending over Sunghoon's side and stroking him fast. Sunghoon spurts streams of cum into Sunoo's waiting mouth, hips bucking from overstimulation as Sunoo milked him dry. He winces and whimpers, body jerking involuntarily.

Barely a minute to catch his breath, still sweat-slicked and disoriented, before Sunoo climbed back on, sinking down again with a satisfied hum.

"What are you doing?" Sunghoon mumbled, pushing back his damp bangs and peering up through half-lidded eyes.

Sunoo giggled, clearly enjoying the power dynamic. "I wasn't joking, you know."

"Wha- Fuck!" Sunghoon's protests are cut off as Sunoo resumes bouncing, the sensation overwhelming-borderline painful but intoxicating. Sunoo using him like this, prioritizing his own pleasure without any regard for Sunghoon, only heightened his arousal.

He whimpers Sunoo's name like a mantra, tears pricking his eyes from the intensity. He tried to hold them back, but they spilled over. Sunoo leans down, still moving relentlessly, and kisses the tears away tenderly. "You're doing such a good job, hyung. Letting me use you like a dildo." Sunghoon whined at the praise, a fresh wave of heat surging through him.

Sunoo trails kisses along his jawline, soothing Sunghoon's ragged breaths. "Sunoo, I can't," he whimpered, voice breaking.

"Yes, you can, baby."

Sunghoon's breathing grew heavier, tears flowing freely. "I can't..."

"You're taking it so well, though."

"Mngh..."

"I know." Sunoo tucked a strand of hair behind Sunghoon's ear, caressing his cheek with gentle fingers.

Sunghoon looked up through teary lashes. "I wanna be good for you."

"Yeah?" Sunoo's voice turned whiny, affectionate. "You are, baby. You're doing so well."

He leaned in for a passionate kiss, tongues tangling as he worked Sunghoon through the overwhelm. Pulling away, Sunghoon whimpered, "It's too much..."

"I know, baby. Just a little longer." Sunoo kissed his cheek, then places his hands back on Sunghoon's chest, speeding up his bounces with renewed vigour.

Sunghoon grips Sunoo's arm hard enough to leave marks, nails digging in as Sunoo reached his climax - rubbing frantic circles on his clit, body shuddering. He collapses onto Sunghoon's chest, kissing him through the aftershocks, their lips moving in sloppy, breathless sync.

As Sunoo came down, he pulled off with a creamy, wet sound and flopped beside Sunghoon on his back. The room filled with heavy breathing, the air thick with the scent of sweat and sex. Sunghoon broke the silence first, his new post-orgasm confidence making him bolder. "So, uhhh... how come you have a...y'know..."

Sunoo's face flushes an even deeper red, a mix of embarrassment and exasperation. He grabs a pillow and chucks it at Sunghoon's head with a grunt, then bolts for the bathroom, bare feet padding across the floor.

'Damn hate to see 'em go but love to seem them walk away' Sunghoon thinks to himself.
