fault or guilt

Summary:

Whose fault was it, really?

His older brother Chan's because he started grinding against him in his sleep, or Jeongin's because he didn't pull away?

Notes:

I wrote this a long time ago, but was hesitant to post it because I didn't like it as much as the other stories I'm writing. However, since jeongchan are now flatmates, I decided to try and give it an opportunity!

Work Text:

Having an older brother who studies and lives in the capital has its perks. For example, Jeongin can go visit his friends, or go to clubs or events in the big city, and he'll always have a place to sleep.

Chan's apartment isn't too big, but he could never say no to Jeongin, a fact that the younger one doesn't hesitate to exploit on multiple occasions. Like today, with Jeongin spread out on Chan's big double bed, ready to sleep early so tomorrow he can get up as soon as the sun rises and go to a video game convention with a friend. And yes, Chan has a sofa, but the bed is big enough for two, and Jeongin's puppy eyes are his brother's weakness, so of course Chan relented.

Jeongin shifts on the bed, hands brushing over the soft sheets repeatedly, until he gives in and smells that faint scent that clings to even clean bedsheets. Warm, woodsy. An inviting layered aroma that Jeongin has become partial to.

Chan's scent.

Tonight Chan is away at a university party, and Jeongin absolutely doesn't care —he has the apartment's keys, after all—. On the contrary, he's happy that he can revel on the soft sheets and their intoxicating scent openly. Chan has his own, grown up life, apart from Jeongin. And well, Jeongin learned early on that the affection of their brotherly bond wasn't really equilibrated.

Whatever. He's learned now.

As drained as Jeongin was after the long train ride to the capital, when he gets into the bed, sleep eludes him. He tosses and turns, prisoner of that strange limbo between being awake and falling asleep that he unfortunately knows so well. 

Time passes slowly, but also not. He must have stayed like that for quite a while, because the next thing he knows, he hears the door of the apartment, and then soft steps padding around. Chan's back already? That was early for a uni party. Still, he's half asleep and too tired to bother mustering any kind of human speech, so he ignores his brother in favor of sleep.

Things get a bit muddled from then on. He thinks he hears Chan entering the bedroom, on soft steps and closed lights. In his mind everything’s black and fuzzy, but he feels his brother getting into the bed, the mattress dipping slightly beneath the new weight. Then there's blackness again, his consciousness floating in the first stages of sleep.

He is pulled back awake when big, hot hands find his torso, caressing his sides over Jeongin's nightshirt. Jeongin's breath stills in his throat. Chan's hands are big. And Jeongin’s waist is thin, so they feel even bigger, like they could encompass him entirely. Jeongin doesn't move a muscle. He's well aware of his older brother's habit of grabbing people just because (he's been on the receiving end a few treasured times), but here, in this setting, it feels different.

Chan stays like that, breathing softly and rhythmically, just holding him, so Jeongin tries to relax. He really should sleep and tamp down those butterflies that are threatening to erupt in his belly. This means nothing to his brother. He probably thinks Jeongin is a pillow, or something.

But then Chan pulls and drags Jeongin’s body back, until he's flush against his brother. 

“Wha— Chan?” Jeongin whispers, protesting his brother's antics but still unwilling to disturb the quiet by raising his voice.

Chan can't be awake, can he? He wouldn't bother Jeongin while he's trying to sleep. Maybe he’s drunk? But Jeongin doesn’t smell any alcohol, and Chan isn’t doing anything else that would point towards him being inebriated. 

No reply from Chan comes. Just the steady type of breathing that indicates that Jeongin's right, his brother is unconscious and just being his touchy self while in snoozing form.

Chan’s arms are big, so big around him, they cage him completely in the most satisfying way. He’ll never admit to anyone just how many times he’s dreamed of being held this way, so very different from Chan’s usual brotherly hugs. Jeongin feels like he could choke on the warmth starting to pool in his core.

Still, he forces himself to relax for both of their sakes, even if his pulse is lightning fast and deafening in his ears. His insides have become a riot of all the feelings he shouldn't feel for his brother, set free in the cover of the night.

Soft breath brushes the nape of his neck, prompting a shiver to travel through his body. They're so close. The secret object of Jeongin's attention is pressed flush against his back, encasing him with his muscled arms. Jeongin is already dreading the moment these arms will let go. It feels too nice, like a dream he will soon wake up from.

Jeongin closes his eyes, determined to ignore the mixed feelings warring inside him and sleep once and for all. By sheer force of will he manages to relax, melting in his brother's warm embrace in a way he wouldn't be able to if they were awake, relishing in the warmth coming from his big frame.

Chan shifts behind him, but Jeongin pays it no mind, too happy in his brother's arms. Until the shifting repeats, this time with more force, and he feels it. Again. And again. In a motion too distinctive to mistake for anything else. His brother, half hard, is grinding against his ass. 

He inhales, quickly, his body going rigid. 

There's no way this is happening.

Common sense slams into him in the next breath and Jeongin moves to put some distance between them. He was happy to be hugged by Chan so closely, but this is crossing a line that neither he nor his brother —unconscious as he is— are ready for. He tries to twist and shift away, to turn over and face Chan, but his brother's muscled arms are like a prison, unmovable around him. The only thing he achieves is squirming pressed on Chan's stronger body, his hardness rubbing even more against him. Jeongin’s helplessness is mortifying. His neck burns, as if his very blood were on fire.

His brother's breathing, ironically enough, remains rhythmic and constant through all the ordeal. Which means Chan is really doing this asleep, unconsciously, most probably having a horny dream while completely unaware that he’s enacting it on the sleeping body closest to him, which happened to be his younger brother’s. Jeongin wants to whimper, to get away from all of this, but there’s a warmth suffocating him that tells a different story.

Chan's movements don't stop, a continuous grinding of hips, seeking relief in the friction. Soon, his brother is fully hard, and Jeongin shivers when he feels that hot length distinctly against him. It doesn't help that Jeongin had fingered himself before sleeping, relieving pent up tension when he was alone. His rim is sensitive, and the constant rubbing and pressure on his entrance begin feeling too good to ignore.

His eyes burn at the unadulterated want inside of him. He knows he shouldn't, but he wants so much. He should be resisting harder, he should push his brother away, but he. Wants.

Chan makes a soft and sleepy sound behind him, and Jeongin feels like he’s drowning in a sweet blend of desire and guilt. Even if Chan is the one doing the grinding, he isn't conscious, doesn't know that the body in his arms is his little brother's. 

Who, then, is really the unwilling party here?

One of Chan's hands lets him go, but before Jeongin can begin thinking of breaking his hold and moving away, his pants are dragged down in one fluid movement. His blood freezes, drops morphing into carmine icicles. The world seems to still in the space of time before Chan grinds against him anew, this time with skin directly on skin.

Jeongin muffles a moan on his pillow, hands grabbing his brother's forearm, to stop Chan or to ground himself, he doesn’t know. The hips retract before coming back, the glide between his cheeks slick and delicious. Jeongin knows he's not dreaming, but he doesn't know what to do with himself because what's happening is straight from one of his forbidden wet dreams.

He should feel bad at having his body merely used for another's pleasure, he should be repulsed at who is behind those sinful grinds, but he must be more twisted than he thought because he doesn't attempt to move away. He’s pinned right there, by the size of his dark desires and by the impossibility of the situation. So he stays put, like a warm body for his brother to use, to grind until he comes and falls asleep, satisfied at last.

Jeongin has already accepted this sequence of events, which is why he doesn't expect it when the grinding stops, and the hand leaves him again. 

In hindsight, maybe he should have guessed.

Because the next contact is not a sliding stroke between his cheeks, but a hot pressure against his rim. 

Jeongin stills. 

Then he begins trembling. 

His brother pushes forward, the head of his cock sinking into Jeongin slowly but smoothly, aided by the remaining lubrication from earlier in the day. Jeongin chokes on a whimper, all his senses focused on the sensation of Chan’s cock going into his body. His hand flies to Chan's hips behind him, to hinder him, to stop him, but his strength is like melted butter against his brother's strong muscles.

Chan presses further in, and Jeongin bites the pillow to muffle the shout threatening to leave his throat, already feeling impossibly full. His brother is big. And gods, how is this even happening? To Jeongin? His brain is stuck in a loop because that's Chan's cock penetrating him. There is no single universe he imagined this ever happening to him.

Oblivious to his younger brother’s plight, Chan continues his slow but sure rolls of his hips, every thrust sliding deeper. It feels wickedly good, bordering on overwhelming, and Jeongin feels like he can't breathe. 

On the next grind, Chan sheathes himself fully into his body, and the sensation is nothing short of euphoric. Jeongin claws at the bedsheets, spine arching at the all-encompassing feeling, but his brother's arms are an iron hold keeping Jeongin's body securely joined with his.

Chan’s hips draw out, and Jeongin’s breath whooshes out of him. He shuts his eyes, knowing what's coming next, and not at all ready for it. Chan begins a slow rocking of his hips, and just after a few strokes, Jeongin’s eyes are rolling back at how sinfully good they feel. 

He bites his lower lip to stifle a moan. This is it. His own brother is fucking him in his sleep, thinking he's just a warm body to fuck. Chan is probably following his instincts from within a wet dream, unknowingly replicating the dream's actions with his physical form.

Jeongin was just unlucky —or lucky— to be the closest body he found.

Chan's thrusts jolt Jeongin with every stroke, and they're firm and nice and just how Jeongin likes to be fucked. He feels so overwhelmed, he thinks it might not take long before he comes, just like that, on his brother's cock.

Jeongin muffles his little pleasured sounds as best as he can on the pillow. He knows they just crossed a line, although he wouldn't be able to say who did the crossing. However, he won't risk his brother waking up like this, so he does his best to stay quiet, even if Chan's hips are determined to make him fail. How is his brother so good at this, while asleep?

He forbiddenly wants to know what sex is like with Chan when he's awake. 

Chan's slow rolls are relentless, making Jeongin melt further, stoking the fire in his belly with sweet glides against that special spot inside him. He's leaking and he must be making a mess, but he doesn't move his hands to touch himself. Instead, he chooses to keep holding on to the older, one hand on Chan's forearm where he's keeping Jeongin in place, and the other on his hip, useless as it is to stop him. Chan's body is so big and strong, of course it would translate to this, to powerful and controlled thrusts that know so well how to scramble his thoughts and make him mindless with pleasure.

Jeongin has only come from his prostate alone once, a one night stand with a particularly dedicated partner, but he feels a certain kind of thrill that his brother's skillful movements are about to take the second.

“Oh, gods…” he whispers and bites his lip, fighting not to moan, or rather shout, at the overwhelming amount of pleasure pooling in his belly.

He's trembling, breathing heavily, and his eyes roll back as his orgasm cascades over him, blinding him. Chan grunts behind him when Jeongin’s muscles spasm, but keeps his rhythmic thrusts, undeterred by his younger brother orgasming around him.

Jeongin slumps into the bed, feeling like his blood is thrumming alive as he comes down from his high. Chan continues moving into him, still asleep and perfectly ignorant of his actions, ignorant of the fact that he just made his younger brother come untouched on his cock. 

With Chan not stopping, the pleasure takes a sharp turn towards oversensitivity. Jeongin squirms to try to get away when it becomes too much, but Chan's arms keep him exactly where the older wants him. His muscles shake, his skin feels like it’s on fire, but still Chan fucks him.

By blessing or by curse, Chan's thrusts begin speeding up, his older brother eagerly chasing his own end. Jeongin can’t help the ragged whine that leaves his lips because even if he just came, every slide of Chan’s cock keeps brushing that special spot in a way that’s going to drive him mad.

Jeongin's panting, jolting with his brother's powerful thrusts, well on the way to become aroused again, when Chan comes, releasing deep inside him. Jeongin blinks at the darkness of the room in front of him, mouth parted at the sensation of his brother's warm release.

Chan just came inside him.

Chan just fucked him while asleep.

Jeongin's heartbeat thunders loudly in his ears. He doesn't have enough brainpower to process what just happened, and he doesn't think he ever will.

None of them move for a long while. Only soft pants sound across the room while they stay like that, joined.

Gradually, Chan's arms grow lax around him. Jeongin waits only a few moments before dark curiosity gets the best of him and he turns his head, just enough to see his brother. Soft curls, strong nose, sinfully plush lips. His brother really is sleeping, with his long, innocent lashes resting against fair cheeks. One part of Jeongin finds it hilarious that he just got fucked so well by a man who was sleeping.

He continues staring at his peacefully unaware brother, breathing softly in his sleep, and wonders what he should do. Should he… get up? Go sleep on the sofa? Wake Chan and explain? Clean both of them and pretend nothing happened? And what after? Will Chan feel guilty? Will he never let Jeongin sleep here again? Will he start avoiding him, cut all ties with him?

Jeongin's vision becomes blurry as hot tears flood his eyes. He doesn't know. He has no idea what would be the best option, and he doubts anyone could help with that decision.

Defeated, he turns back and buries his face on the pillow, trying to keep the tears at bay, to calm his shuddering breaths.

He falls asleep before he can come to a decision.

 

And he would have stayed asleep, if it weren't for his brother. Again.

This time, he's woken up when hands grip his waist and turn him, forcing him to lie on his front. Jeongin groggy from sleep, can't really open his eyes, until he feels his legs being parted wider, and a hot pressure against his entrance. 

He hasn't mustered enough coherence to move his limbs when Chan's hard cock breaches him. It's like a bucket of cold water. Jeongin becomes wide awake, scrambling to find any kind of purchase to get away, but it's useless. His brother has one mission only, and that is to fuck. Before Jeongin can do anything, Chan has hilted into his body.

This time it's laughably easy. Aided by Chan's come, the glide is perfectly slick, his hot member sinking fully into him with no resistance, like Jeongin's body is welcoming his brother. Jeongin whimpers at the prospect of being fucked not once, but twice. However, it's not only dread in his gut, but there's also a tendril of thrill that intertwines with it.

Jeongin has never been more aware of his brother's muscled physique. In this position, Chan can brace his strength, and Jeongin feels it in the strong and firm thrusts of his hard cock. Jeongin's mouth falls open at the sheer pleasure each stroke brings, fighting a losing battle at holding back his sounds. His brother is just too good at this.

Soon he's panting, sprawled on his front with his hardened erection rubbing against the bedsheets increasing the stimulation. Jeongin can't help feeling like a doll, with no regard for his thoughts or wants, just used for Chan's pleasure. Even if it’s a pleasure he’s seeking while asleep. The thought does something to his brain, and coupled with how good it feels to be fucked in this position, it sends Jeongin over the edge. He does his best to contain his moans as he shivers through the aftershocks, a last-ditch effort at not waking up his brother to find them like this, with Jeongin being pathetically unable to stop an unconscious man from fucking him.

Once again oblivious to his younger brother's climax, Chan doesn't stop his thrusts, and instead keeps rutting into him in that damning perfect angle. Jeongin digs his fingers desperately into the bedsheets, feeling like he'll choke at the heightened sensitivity. But when the worst of it passes It's like he doesn't come down fully from his high, and instead, his body begins another climb towards the edge.

Jeongin lets his head hang down, and he thinks he might be drooling at the onslaught of sensations. The sound of skin slapping against skin resounds loudly in the bedroom, just another proof of the affair currently going on that probably only Jeongin will remember. Chan's hips pound the breath out of Jeongin, jostling him with every slam, but Chan’s bigger body keeps him exactly where he wants him.

By that point, he's doing a poor job of restraining the sweet overwhelmed sounds spilling from his lips. His core is coiling tighter and tighter, and his body begins quivering. Chan must be close too, because he increases the tempo of his hips and Jeongin nearly sobs, the pleasure too big to contain in his smaller body. With one particularly well aimed thrust, the tension snaps, and pleasure detonates inside of Jeongin like he's never felt before.

He’s tangentially aware of Chan finishing inside again, but his thoughts feel floaty, pleasure mixing with exhaustion. His eyes fall closed, and he's too lost to the world to feel his brother slumping on top of him, and then shifting them to their sides.

He only knows darkness, and sleep.

 

The third time Chan wakes him up, Jeongin doesn't even open his eyes. He recognizes Chan's hot hands as they lift his leg, recognizes the body as it shifts closer to him, recognizes the hot shaft as it penetrates him.

Soft puffs of hot breath brushing against his face are the novelty, but it cements his decision not to open his eyes. He doesn't want to see his older brother while he fucks him. The knowledge of the two past rounds are damning enough.

Chan's thrusts start at a slow and languid pace, like a lover who is taking his sweet time. Jeongin should be spent for the night after the orgasms he's had, but Chan’s thrusts keep rubbing his prostate almost every time. Molten pleasure thrums in Jeongin's veins, coaxing soft sighs out of the younger, who's too tired to reign them in anymore.

Something that's probably a strand of his hair brushes against Jeongin’s cheek, but the touch is forgotten as soon as it happens.

The body in front of him closes the distance between them, wrapping thick arms around the younger’s waist. Jeongin is prepared to surrender to his brother speeding up to chase his orgasm, but is surprised when Chan uses his hold to flip them, leaving Jeongin prone on top of him.

Jeongin keeps his eyes shut, both too tired and too stubborn to open them. He doesn't need to do anything though. Chan plants his feet firmly on the bed and Jeongin feels his stomach drop.

No fucking way Chan is going to

The first thrust in that position effectively makes his thoughts halt, pleasure sharp and tight in his belly. Then Chan repeats it, again, and again, and it feels so good so quickly that Jeongin's mouth parts as he fights and fails to tamp down on his moans.

His body tenses and the pleasure mounts, unbidden and unrestrained, as Chan rams into him in that damned position. His strokes are short and quick, and they have Jeongin bouncing on his brother's cock while powerlessly slumped over his torso. It feels demeaning and perfect and Jeongin is really going to come again like that.

He wanted to keep his eyes closed through this third round, but at a certain point he honestly doesn't know if he succeeds because his eyes start rolling into the back of his head at the huge amount of pleasure that's cresting in his core. His moans are ragged and shuttered thanks to Chan's thrusting, who's breathing heavily while pistoning into the younger’s too pliant body.

It doesn't take them long to reach their climax, with Jeongin shooting his release between their abdomens first, and Chan inside Jeongin shortly after. They spend the next handful of seconds just breathing heavily, coming down from their respective highs in their embrace.

In a surprising and tender gesture, Chan rubs Jeongin's spine over his damp shirt, brushing up until he reaches his nape and cards his fingers into his hair. Jeongin lets himself be soothed by his older brother, melting onto his bigger body.

He's exhausted, so far gone that even if he's aware of general physical action, half his brain is floating, drifting away in the beginnings of a dream.

One breath he's on top of Chan, but on the next, he's on his side once more, facing Chan. He turns over, subconsciously trying to put a greater distance between him and Chan, wanting this night to be truly over.

Soft lips press against his temple in a fleeting touch.

“Sleep well, Innie.”

The blood in his veins becomes ice, his body seizing at the sound of his brother's voice.

It can't be.

It can't be. It can't be, it can't be—

The mattress shifts as Chan lies back down behind him, and Jeongin stops breathing altogether when his warm body encases him in a move that’s now entirely too familiar, and a possessive hand slides over his side, and down his stomach.

His whole body is rigid, mind circling over Chan's kiss, Chan's voice, Chan's words. Does Chan talk in his sleep? Is that it? Was the kiss part of his dream too, his body subject to whatever his mind is conjuring?

Or…

If he turned over, if he looked, would he find Chan awake?

He stays awake, muscles tensed in fight or flight mode, thoughts trapped in this never ending loop of thoughts. But when nothing else happens, he feels the adrenaline rush slowly making him crash, until he’s too tired to fight the sleep claiming him.

 

Jeongin wakes up, alone, to the sound of his alarm bright and early, the way he set it the day before in order to be one of the first to arrive at the game convention. He shoots up from the bed, pawing at his phone on the nightstand to stop the loud ringing, when he feels it. His body, achy all over, and especially his—

His hand clenches around his phone and his eyes widen as the memories pour into his head.

He and Chan had sex.

His brother moved while sleeping, and Jeongin wasn't able to fight him, so they had sex three times and at the end—

Chan opens the door to the room, in his pajama bottoms and hair still mussed from sleep, and saunters to the bed.

“Good morning! Good to see you're awake, I thought you might sleep through your alarm,” Chan says, climbing back up to the bed and grabbing his own phone to scroll through his notifications.

Jeongin feels like pinned down prey. He doesn't move, he can't, because the aftermath of what they did is clearly visible on the bedsheets, on their clothes and even on their bodies. Yet Chan is acting like it's just another regular morning, like they just slept peacefully through the night and woke up now.

“Shouldn't you hurry? Your friend’s waiting for you, isn't he?” Chan asks, sparing one glance at him before going back to his phone like nothing in the world could ever be wrong.

So Jeongin moves, feeling heavy because of the knowledge of what happened, but feeling dazed because of the very real possibility of Chan knowing it, too.

And seemingly be… okay, with it.

Notes:

Thank you for reading! If you're curious to know which rounds Chan was actually awake for, it's the 3rd one, although the 2nd one is up to the reader's choice 😂

Also I promise I'm working on lots of other stories, including "capturing the rival team's omega" epilogue. I'm just a very slow writer so I hope you'll bear with me! (Also, my to-write list currently has 70 items 😱)
