Work Text:
Kim Seokjin considered himself level-headed, rational more often than emotional. Above almost everything else, Seokjin valued his self-control. It was the reason why he was his organization’s youngest associate director at just 23. He worked extremely hard to succeed, avoiding most temptations.
And then, Jeongguk appeared in his life.
“I have a favor to ask of you, son,” his father had started during an unexpected evening phone call. Seokjin stood and stretched, quickly packing up for the day. He was tired, looking forward to a hot bath when he returned home.
“Is everything alright, dad?” It was unlike his father to ask anything of his children.
“Yes, yes, well. There’s something I never told you.”
A 15-year-old brother. Seokjin had a 15-year-old half-brother his father had never told him about. He’d been aware of his father’s past infidelity, but he never had a reason to believe he was caring for a secret family hundreds of miles away.
“She… was ill, and I was paying for her treatments, but. Well, the sickness was too much for her. And now her son, your half-brother…”
Apparently, the kid had no close relatives on his mother’s side. And since he was still a minor—
“I promised her I would adopt our son when the day eventually came,” his father continued. “I was going to tell you earlier, but… her passing happened a bit sooner than expected.”
So, his father promised this woman that he would take in their child, a child that Seokjin’s father may have never even met in person. But his father wasn’t willing to raise another kid, not when all of his sons were grown.
Seokjin was the youngest, and he also owed his father something; without him, Seokjin would be in a ton of debt from his schooling. Of course his father would never ask him to pay back the money, but he would ask for something like this. Two years and three months until the kid graduated high school. Until then, he needed a new home.
At the time, Seokjin felt more annoyed than anything after agreeing to his father’s “request” – as if he could ever say no. He tried to remind himself that it could’ve been worse; the kid was nearly grown so Seokjin wouldn’t need to act as some parental figure, at least.
Maybe that would have been for the best, though, if Jeongguk had appeared in his life when Seokjin was 15 himself. That way, he could’ve met Jeongguk when the kid was 7, and then he really could have viewed him as a younger brother. An innocent child for him to help his parents raise.
Jeongguk did not look like a child at 15. Yes, his face was youthful, bright skin and brighter eyes, but he was as tall as Seokjin. His clothes looked too small on him – evidence of a recent growth spurt.
These were not the features Seokjin would notice immediately. No, his eyes were drawn to the fluffy brown rabbit ears on top of Jeongguk’s head.
He couldn’t help but stare. Was Jeongguk wearing a bunny ear headband or….
“He didn’t tell you?” His new half-brother mumbled, his expression turning sour. “I’m a rabbit hybrid, if you didn’t know. Never met a hybrid before?” He must have been referring to Seokjin’s stunned look.
“I’m sorry for being rude, ah, Jeongguk,” Seokjin hastily said, moving aside so Jeongguk could walk inside with his suitcase. Seokjin glanced outside, seeing a man grabbing more bags from the car. He decided to go help with the rest of the belongings.
“I’m a friend of Jeongguk’s. Name is Yoongi,” the shorter man greeted him and—
He had cat ears. Ah, he was a hybrid like Jeongguk. He seemed a bit older, closer to Seokjin’s age. When they walked into his house together, Seokjin noticed the long tail sticking out of a custom hole in his pants.
Of course Seokjin knew that hybrids existed. Nearly a century ago, some scientist had discovered how to genetically engineer human-animal hybrids, such that a pregnant mother could take a special hormone that would alter the DNA of the fetus successfully. It wasn’t until those first hybrids became pregnant that scientists found that most hybrids were sterile, but those who weren’t would always pass on their animal features to their offspring.
Such genetic altering was highly controversial in most societies. In his country, about four million adult hybrids were included in the census last year. Of course, hybrids had the same rights as every other person, and the genetic modifications seemed to have little impact aside from cosmetic changes. However, many people viewed hybrids as lesser beings and their harmful stereotypes often gave hybrids a disadvantage in life.
“You didn’t deem the fact that the kid is half rabbit important information to tell me?” Seokjin asked as soon as his father answered his call that night.
“He isn’t half rabbit – you know that isn’t how hybrids are created, Seokjin,” his father countered sternly. “His mother was also a rabbit hybrid, as I’m sure you’ve deducted. We didn’t think she was able to become pregnant, but when we realized we were wrong… it was already quite far into the pregnancy. Trust me son, I did not wish to bring another hybrid into this world.”
Seokjin knew that his father was speaking not from a place of hatred or disdain, but pity.
“I’ll try my best to take care of him, dad,” he said. Inwardly, he just hoped that the kid would warm up to him. Jeongguk had barely said a word as they worked to unpack his belongings and set up much of his room.
///
The first few meals spent together were tense. Jeongguk thanked Seokjin for the food and stared at his plate as he took small bites.
“Not hungry?” Seokjin asked one evening after dinner, noticing that Jeongguk had eaten barely half of his food.
“I don’t like sushi,” Jeongguk murmured as he stood with his plate, not expecting Seokjin to comment on it. “But thank you for making it,” he added as he set the plate on the counter and pulled a storage container out of the overhead cabinet.
“I told you this morning I would make sushi tonight, why didn’t you tell me then that you didn’t like it?”
“I don’t wanna seem ungrateful.” Jeongguk stood staring at the cabinet for a moment, his stature looking small from Seokjin’s position. “You should just cook whatever you want.”
Seokjin smiled to himself and stood from his chair, gathering his own plate to set in the sink.
“Silly,” he commented after washing his hands, ruffling Jeongguk’s hair playfully even though the other wouldn’t look at him. “This is our house now, and in this house, we eat foods that we both like to eat.”
“O-Okay, got it,” Jeongguk nodded stiffly, still not looking at him. The back of his neck was turning red, his rabbit ears twitching seemingly nervously.
He warmed up to Seokjin pretty quickly after that. Soon enough, they were having engaging conversations at dinner, laughing together on the couch watching funny movies, texting each other stupid memes during the work/school day.
‘Is this what it’s like to have a younger brother?’ Seokjin wondered. After about a year of living together, he considered Jeongguk to be more like a best friend, someone he unexpectedly connected with on a deep level. Sure, maybe he could be a bit annoying like a little brother at times, acting childish when he was tired or pushing Seokjin’s buttons when he was bored. Jeongguk was intuitive, though, never overstepping his boundaries because he was able to read Seokjin’s mood accurately these days.
Sometimes, he even let Seokjin inside. Usually, he kept any worries to himself, not wanting to burden his older half-brother. (Seokjin had tried telling him again and again that he was truly happy to be living with him and providing for him, but the kid wouldn’t overlook the fact that he was pretty much thrust upon the elder out of the blue and interfered with his life.) Sometimes though, they’d be watching a movie together, with Jeongguk nearly falling asleep on his shoulder. And he would say something along the lines of, “the other guys at school think I’m a freak,” or, “I wish I could be like you, Seokjin-hyung.”
Jeongguk was a good kid. He gave Seokjin something to look forward to after work, someone to come home to. He was kind, too smart for his own good at times, charismatic once he opened up, and also troubled on the inside. Most people were. Seokjin knew his little brother had it worse than most though, facing prejudice nearly every day. And despite that, he still smiled brightly every day.
Jeongguk was one of the most incredible people Seokjin had ever met. Anyone who viewed hybrids as lesser beings were ignorant, bigoted, or both.
And in that first year, Seokjin thought what he felt was admiration. Or at least, that’s what he could tell himself and make himself believe. But he and Jeongguk grew so close during their time together, and the kid was apparently very touchy-feely with the people he liked. An arm around his shoulder when they watched a video on his phone, Seokjin could handle that. Even the wrestling seemed innocent enough, though it often left him breathless for mostly impure reasons.
But then Jeongguk started cuddling up to him on the couch during movies, and it felt so intimate compared to everything else. Maybe it was the dimmed lights, or the blanket covering most of their bodies, hiding everything. Or maybe it was just Jeongguk, pressed so close to him, one of his cute bunny ears flopped across Seokjin’s chest, his smooth skin making Seokjin feel almost feverish.
And then the dreams started, and he woke up craving what he couldn’t have. Suddenly, he couldn’t look his little brother in the eye without feeling a rush of shame and longing.
‘He shares 25% of your genes,’ he reminded himself one morning after another dream. But was that a deterrent or a justification?
///
It happened a few months after Jeongguk’s 16th birthday.
Seokjin returned home from work and called out to his little brother, expecting his usual greeting. When he heard none, he walked up the stairs to Jeongguk’s room curiously, knowing the other would tell him beforehand if he wouldn’t be home.
The hallway smelled strongly of lavender, and Seokjin quickly found the source. Knocking on the bathroom door, he called his little brother’s name.
“You don’t need to come in….”
Jeongguk’s voice sounded strained, almost as if he was in pain. Alarmed, Seokjin swiftly opened the door, expecting a steam-filled bathroom. Instead, he found the air clear but saturated with lavender. Looking towards the bathtub, he saw Jeongguk sitting slumped over, his head resting against the wall.
“What’s wrong, Jeongguk?” He said quietly, knowing that something was off but not sure of what was going on. Jeongguk’s eyes were closed, his cheeks red and his lips parted, his chest rising and falling sharply. Seokjin stepped closer and noticed that the bath water was pinkish-purple, clearly full of bath bombs or something similar. It was opaque and his little brother was submerged up to his waist.
Jeongguk’s eyes opened as Seokjin came closer, and immediately his pupils dilated as they landed on him. “No, Seokjin-hyung,” he murmured, his voice sounding so small, tears welling up and threatening to spill.
“Jeongguk!” Seokjin exclaimed at the sight of his tears, anxiety crawling up his ribs. “What do you mean ‘no’? You want me to leave?”
“No, don’t leave!” Jeongguk shook his head, leaning towards Seokjin now, and Seokjin felt so confused but moved closer, trying to process the situation. His little brother had never behaved quite like this before; he seemed so vulnerable. Jeongguk trembled at his closeness, and then suddenly he was raising his arms above the water and leaning over to wrap them around Seokjin’s shoulders.
Seokjin jumped in shock, both at his brother’s sudden proximity and the fact that his shirt was soaked with cold water.
“Jeongguk, the water is…” Seokjin said, reaching his arm into the tub to touch the water as Jeongguk clung to him. “It’s freezing! Jeongguk, do you have a fever? Please, tell me what’s wrong.”
Jeongguk made a sound that Seokjin could only describe as a whine, and instead of answering, he nuzzled his face into the crook of Seokjin’s neck, inhaling deeply.
“You smell so good, Seokjin-hyung,” he breathed, holding Seokjin even tighter.
Seokjin’s head was spinning. His little brother’s behavior gave him a loss for words, and his voice was reminding Seokjin of his illicit dreams, his lips against his neck electrifying. At a loss, Seokjin awkwardly grabbed Jeongguk by his shoulders and began trying to hoist him up out of the cold bath.
“You’ll catch a cold, come on, let’s get you out,” Seokjin said with as much authority as he could muster, but Jeongguk tensed up, resisting and trying to pull Seokjin closer instead, refusing to leave the water.
“W-wait, hyung…” Jeongguk murmured, his face reddening further. Seokjin momentarily stopped his pulling, waiting for him to continue. “I, um… stopped taking my suppressants.”
Suppressants? Seokjin racked his brain. Was his brother referring to heat suppressants? No, he was a male, so he didn’t go through heats but instead… ruts? Yes, ruts. At least, that is what Seokjin knew of hybrid biology, which was admittedly little. In actual mammals, only certain species like cats experienced such a mating cycle. But in hybrids, the cosmetic changes were often accompanied by hormonal changes that resulted in a mating cycle of sorts.
This was one of the primary reasons why hybrids were discriminated against in many societies. In their society, the majority of hybrids took a daily heat or rut suppressant unless they were actively trying to become pregnant. Seokjin knew this, but for some reason he never considered that Jeongguk must have also been taking suppressants at his age.
“Why did you stop taking them, Jeongguk?” Seokjin said delicately, allowing his brother’s tight grip.
“…made me feel lousy,” Jeongguk murmured, pouting his lips against Seokjin’s throat, as if kissing—
“So y-you’re in rut right now?” Seokjin steered on steadily, refusing to acknowledge his brother’s sudden affection. This was just his hybrid biology; his little brother didn’t understand what he was doing.
“No…. I…” Jeongguk stumbled, his fingers trembling against Seokjin’s shirt.
“It’s okay Jeongguk, don’t be embarrassed,” Seokjin said softly, assuming he was too ashamed to admit it. “There are ways to— There are these, well, toys,” he coughed, his own face heating up. What else would he call them? He knew from watching porn (no, not specifically rabbit hybrid porn, though it did pop up sometimes) that special sex toys were created for hybrids going through heat or rut. “Basically, well, you’re 16, I know you must know what a fleshlight is.”
“Jin-hyung… you don’t understand,” Jeongguk said against his skin, a whine in his voice. “I don’t need… that…” he continued, now moving an arm to grip one of Seokjin’s hands and push it into the water.
“Wait, Jeongguk—” Seokjin gasped, watching exactly where his brother was aiming his hand, between his legs in the opaque water. Jeongguk was quick though, and before Seokjin could pull his arm back, his fingers touched soft, smooth skin—
Seokjin jerked his arm and body away as if burned, breaking out of Jeongguk’s hold as water flung everywhere.
Jeongguk, he— somehow, he had—
His mind racing, Seokjin didn’t immediately act when his half-brother’s eyes stared at him stunned and hurt. But then his big eyes filled with tears, his face crumbling, his small voice saying, “You think I’m a freak…” and Seokjin moved back hastily, hesitantly touching Jeongguk’s shoulder.
“No, Jeongguk, you’re not! I’m sorry, it’s just that as your older brother, I-I can’t touch you like that,” he rushed to say, his mind still jumbled, but he couldn’t let Jeongguk feel bad for being who he was. He had no control over his biology, and yes, he may have been a rare type of hybrid but that didn’t change who he was as a person.
Seokjin tried to focus on his noble intentions of comforting Jeongguk, instead of his forbidden thoughts of lustful wonder.
“I don’t care,” Jeongguk stated firmly, once again latching onto Seokjin. “It’s okay Jin-hyung, you can touch me.”
Seokjin shivered and he hated himself for it. Gently, he insisted, “I’m your brother, Jeongguk. It’s wrong. Your hormones are clouding your judgment.”
He expected Jeongguk to qualify his statement, saying “you’re my half brother,” as if they didn’t still share the same blood, but Jeongguk just said,
“I don’t care if it’s wrong. I’ve wanted you since the beginning.” Jeongguk grew bolder with his confession, mouthing at Seokjin’s neck, his pouty lips wet and perfect—
“Stop,” Seokjin said, weakly pulling away, hating his desires, telling himself that Jeongguk was just saying anything in order for Seokjin to give him his—
Fuck.
“Listen to me, Jeongguk, I’m going to take care of you, but I can’t help you like that,” he said sternly, standing and ignoring Jeongguk’s petulant whine as he moved to the towel rack. He needed to leave and drive to the nearest sex shop, get away from his hormone-riddled little brother. But he couldn’t allow him to just stay in that freezing water whilst he was gone. “Stand up,” he commanded softly, holding the towel up.
Thankfully, Jeongguk listened to him without complaint, standing. The water noisily ran off his body and Seokjin averted his eyes, not letting himself see. Jeongguk took the towel and merely held it in front of his crotch area, saying, “it’s too hot to wear this…”
Seokjin sighed in defeat and simply told his brother to go to his room while he went to the store.
“I want to stay in your room,” Jeongguk insisted, pout evident in his voice, and Seokjin just said OK. He looked up at the ceiling as Jeongguk brushed passed him on his way out, not letting himself glance at Jeongguk’s bare figure.
Of course, Seokjin left his keys and phone in his room, so he didn’t have a choice but to follow his little brother, avoidant with his gaze. Jeongguk immediately dropped the towel on the floor and plopped down on his bed, burying his head into Seokjin’s pillows and moaning.
Seonjin’s own body was beginning to feel hot. His little brother was feeling good just from inhaling Seokjin’s scent. He tried to ignore him, his eyes trained on a spot on his wall as he grabbed his phone from atop his dresser.
“Please don’t leave,” Jeongguk said quietly as he lifted his head, and Seokjin could see from the corner of his eye that his little brother had started rocking his hips against the bed and—
Fuck fuck fuck. Seokjin opened his mouth to insist that he had to go buy the toys for him, but Jeongguk continued,
“Text Yoongi. He’ll know how to help.”
Yoongi? Actually, that was right; Yoongi was a hybrid too and had known Jeongguk for longer. Surely, he would know better than Seokjin how to help Jeongguk. Hurriedly, Seokjin sent a text to him, typing, “Jeongguk went off his suppressants and I think he’s in heat.”
Yoongi’s reply was immediate. “I’ll be right over.”
Now, they just had to wait.
“Jin-hyung, lay with me,” Jeongguk requested, rolling on his side, his thighs clenching together. Seokjin wanted to tell him no, he shouldn’t, and he would just wait in the living room.
But Jeongguk wanted him, and Seokjin’s desires were louder than his morals.
He crawled on the bed, laying on his back and staring up as Jeongguk molded himself to Seokjin’s side, his little brother running a hand under his shirt greedily, throwing a leg over his hips.
“Oh,” Jeongguk breathed into his ear, his hips twitching, and Seokjin could feel it, could feel him rubbing himself against Seokjin’s hip bone, getting himself off. Seokjin was hard in his thin pants, feeling the heat radiating from Jeongguk, his leg shifting over the head of Seokjin’s dick every time he grinded against him.
‘If I don’t touch him, it’s okay, right?’ Seokjin let his little brother hump against him, savoring his breathy, excited moans against his ear. He could smell his arousal in the air, curiously sweet, making Seokjin’s mouth water. His little half-brother wanted him and was getting off by using his body. Seokjin choked back one of his own pleased sounds, trying desperately not to reach for Jeongguk’s leg to push it harder against his straining cock.
Yoongi couldn’t get there soon enough. Thankfully, Jeongguk didn’t push Seokjin for more, just kept moving against him and breathing sweet sounds against his skin. After a small while, a knock at the door forced Seokjin to extract himself from his brother, who let him go only to roll onto his stomach as he shoved his hand between his legs. Seokjin swallowed thickly and left the room, adjusting his dick in his pants so Yoongi wouldn’t see how hard he was for his little brother.
///
“Don’t let him leave your apartment,” Yoongi advised after giving him a packaged toy.
“Okay… is there anything I can do to stop his, ah, symptoms?” Seokjin said awkwardly in a hushed tone, mindful of Jeongguk’s sensitive hearing. Yoongi shrugged, crossing his arms. He looked passed Seokjin’s shoulder, his little nose twitching a bit as if surveying the air.
“He’s going to try to have sex with you,” he said calmly, and Seokjin bit the inside of his cheek hard enough to bleed. Yoongi slapped his arm. “Stop that! Calm down,” he said, reaching into his pocket.
Seokjin placed his hand out, watching Yoongi sit a small blue pill on his palm. A suppressant, maybe?
“It’s basically a morning after pill that works for hybrids,” Yoongi explained. Seokjin felt his ears burn red a moment later.
“Morning after? You’re suggesting…” Seokjin couldn’t bring himself to say it.
“Just take it, Seokjin,” Yoongi said flatly. “I would be taking care of all of this if Jeongguk would let me,” he went on. “But he wants it to be you and you’re gonna give in, anyway.”
“I wouldn’t—”
“It’s none of my business,” Yoongi interjected, looking just as uncomfortable as Seokjin felt. Shoving his hands in his pockets, Yoongi fixed him with a piercing stare. “If you do anything that he doesn’t want, I will ruin your life. I mean that.”
///
Unease sat heavy in his sternum as he walked back into his room, Jeongguk’s intoxicating scent hitting him hard. The sight of his little brother on his bed had even Seokjin’s conscience at a loss for words.
Jeongguk was on his back now, a pair of Seokjin’s worn underwear pressed against his face as he spread his knees wide open, his hand between his legs. He rubbed his erect little clit rapidly, moaning unabashedly as he thrust his hips up, his pink pussy wet and plump. Seokjin nearly dropped the toy, wanting to cry in frustration because he wasn’t strong enough for this.
Jeongguk’s needy cunt was calling to him, and Seokjin could only resist so much. Mindfully, he sat the morning after pill safely on top of his dresser.
Jeongguk must’ve realized Seokjin was back in the room, because he removed the used briefs from his face and looked as Seokjin finally gazed between his thighs. Jeongguk groaned and lifted his head, watching Seokjin as he rubbed his clit faster.
“Jin-hyung, it hurts….” He moaned pitifully, his cunt winking open as if trying to draw him in. Seokjin moved forward, arousal coursing through him as he pushed aside his inhibitions, dropping the toy on the bed as he crawled in between Jeongguk’s spread legs.
“You’re perfect,” was all Seokjin could murmur, gently moving Jeongguk’s hand away so he could see his cute little pussy in all of its forbidden glory, completely bald and dripping wet. Seokjin groaned as he just looked at it, dropping his hips to the bed and giving his aching cock some friction, briefly imagining the feeling of Jeongguk’s tight cunt and nearly creaming his pants. His sweet scent was so much stronger up close, and Seokjin couldn’t hold back any more.
Without much thought, Seokjin pressed his lips against Jeongguk’s hardened little clit, giving it a chaste kiss. Jeongguk reacted beautiful, nearly squealing at his older brother’s touch as he pressed his hips up, asking for more. Seokjin gave in to his unspoken request, gripping Jeongguk’s strong thighs and bending them even further so that he had more access to his sweet pussy. Seokjin opened his mouth and dipped his tongue into his little brother’s sopping cunt, moaning at his taste. Somehow, Jeongguk’s natural lubricant tasted just as sweet as it smelled and it was driving Seokjin crazy.
He pushed his tongue inside of Jeongguk’s pussy, trying to drink from his delicious cunt, driving Jeongguk just as wild. His little brother was moaning nonstop, his thighs squeezing around Seokjin’s head and his hips grinding against his mouth.
“More!” he mewled breathlessly, his fingers returning to his clit as Seokjin tongued his dripping hole. Seokjin gently moved his fingers away again, knowing just what his little brother wanted. After one last lick to Jeongguk’s fluttering walls, he trailed his tongue from his hole up to Jeongguk’s aching clit, sharpening his tongue and laving his little brother’s nub rapidly. Jeongguk’s moans increased in pitch, his hips stilling as he let Seokjin work his cunt as he desired.
Seokjin experimented with different ways to abuse Jeongguk’s little clit, flicking it rapidly with his tongue and sucking it between his lips. His younger brother seemed to love all of it, his thighs trembling against Seokjin’s head as his pussy dripped with arousal. Seokjin positioned his hand on top of Jeongguk’s mound, using his thumb to gently tug the hood of his clit back, exposing the most sensitive areas for Seokjin’s mouth. Seokjin tongued the bundle of nerves, moaning when Jeongguk clutched desperately at his hair and grinded his pussy against his older brother’s lips.
“Jin-hyung!” Jeongguk cried out, his body overwhelmed by the pleasure building between his legs. God, Seokjin was already addicted to his little brother’s fucked out voice, addicted to the knowledge that he was responsible for Jeongguk’s pleasure, was about to make his little brother cum from eating his little pussy. Jeongguk’s body trembled so sweetly, obviously close to his nirvana. Seokjin became greedier with every squeal and moan from his forbidden lover, needing to give and take even more.
Sucking on Jeongguk’s erect little clit, Seokjin moved one hand lower, tracing his brother’s quivering hole with the tip of his finger. Jeongguk gasped at the new stimulation, his slippery thighs falling open, inviting Seokjin to be an even more corrupt older brother and fuck his underage pussy with his fingers. The thought only made Seokjin feel hotter, his poor cock shifting against the bed and aching to be enveloped by his little brother’s sweet cunt.
He swirled the tip of his finger all around Jeongguk’s tiny hole, gently laving underneath the hood of his clit, not letting up as he prodded at the twitching rim. He wanted to feel the hot insides of his baby brother but knew that things had gotten completely out of hand by this point.
Seokjin gently pulled his mouth away from Jeongguk’s woefully eager cunt. He looked up at Jeongguk’s face, the first time since licking his little pussy, and promptly regretted his decision to see his brother like this.
His eyes dazed and focused on Seokjin, a deep blush spreading across his cheeks, lips shining and parted, drool drying on his chin. His naked body, tall but still clearly belonging to a developing teenager, somehow completely hairless everywhere but his head. Seokjin reasoned that genetic modification had to be the explanation, but it made Seokjin feel dirtier, like Jeongguk was more of a child than an adult.
Seokjin glanced down, biting his lip hard in order not to groan at the lewd sight of his little brother’s excited, sopping wet pussy, winking open just for him.
“Has anyone ever touched you like this before, Jeongguk?” he said in a hushed tone, as if whispering made the depravity any less real. He was asking his little half-brother if he was a virgin at 16, if anyone else had played with his underage cunt before.
“N-No, Seokjinie-hyung, I wanted it to be you,” Jeongguk whined, rocking his hips impatiently. “You’re making me feel so good, please don’t stop.”
Seokjin wanted to fulfill every desire of his little brother’s especially since they aligned with his own. But he couldn’t take advantage of him, his hybrid brother in some sort of heat cycle, who probably wouldn’t agree to doing this with a clear head.
“I-I’m sorry Jeongguk, but what I’m doing is unacceptable,” Seokjin stated, withdrawing completely from Jeongguk’s pussy. He couldn’t do this, no matter how much he wanted to, no matter much frustration he felt. The object of his desires was literally pleading for him to deflower his virgin cunt. But Jeongguk would hate him once his heat passed if he continued, he knew it. “This toy will help you through your, ah, heat,” he said awkwardly, moving to sit and trying to pretend like his dick wasn’t nearly poking through his slacks.
He reached for the toy to the side, pulling apart the packaging as he turned away from his brother. Jeongguk was quiet and Seokjin didn’t know how he’d react, but once he had the toy out, he turned towards Jeongguk with it.
Jeongguk had his legs closed with his arms crossed over his chest, his face angrily staring up at the ceiling. His bunny ears even seemed to twitch in annoyance. Seokjin would have found the scene cute if they were in any other circumstance in which Seokjin hadn’t nearly fucked his little brother. When he held out the toy for Jeongguk to take, Jeongguk said,
“I don’t want that.”
“Jeongguk,” Seokjin sighed, and Jeongguk sat up before he could say more, snatching the toy away.
“Whatever, just go,” His brother snapped, his face twisted in disappointment. He laid back and spread his legs open again, positioning the toy against his untouched hole. As if he was just going to—
“Stop,” Seokjin said, grabbing hold of Jeongguk’s wrist to stop him from trying to force the toy in. “You can’t just shove it in w-without preparation,” he insisted, feeling as his ears burned red. The whole situation was ridiculous and he was beginning to feel very ashamed. Jeongguk clearly had no idea what he was doing and Seokjin had nearly stolen his innocence.
“Preparation? Like what?” Jeongguk whispered defiantly, his own face heating up again. “It hurts hyung, please, I just need…” he whimpered, and Seokjin could feel the flex of his wrist as he tried to breach his aching hole with the dildo.
“You need lube and you need to stretch yourself, or else you’re going to feel pain,” Seokjin explained, taking the dildo away gently. Poor Jeongguk was nearly in tears, no doubt due to the frustration Seokjin had forced upon him. His baby brother would harm himself in his frenzied state, the lack of experience ensuring that.
“Jin-hyung…”
“It’s okay, Jeongguk, I’ll show you,” Seokjin said, because he could justify this part. He would help his inexperienced little brother by stretching out his tight, untouched pussy, so that he could take the dildo’s girth. Then, hopefully, he could take care of his heat himself, without the need of his perverted older brother.
Jeongguk looked hesitant but allowed Seokjin to smooth out his shoulders, have him relax against the bed. Seokjin gently told him to bend his knees and hold his legs open, which Jeongguk did without pause, eyes lighting up at the prospect of Seokjin finishing what he’d started. Seokjin eyed his plump, glistening pussy and couldn’t resist leaning his face in again, attaching his mouth to the tight wet hole and tasting Jeongguk’s sweet juices.
“Oh!” Jeongguk gasped, lifting his hips up, giving his big brother more access to his wanting pussy. Seokjin could have licked his little cunt all day, in love with the taste, but he reminded himself of his task. Pulling away with a wet kiss against Jeongguk’s taut clit, Seokjin sat on his knees and pressed a single finger against his twitching hole. His little brother was so wet that they didn’t even need to use lube.
Seokjin reminded himself to go slow, be patient for Jeongguk’s sake despite his little brother whimpering for him to touch him.
“Yes, hyung, inside, f-fuck…” Jeongguk’s tensing body shivered just at the sensation of Seokjin breaching his hole, dipping his finger inside. Seokjin watched his face carefully, asking,
“Have you ever touched yourself like this before, Jeongguk?” Seokjin needed to know how he might react, which would largely depend on his experience with fingering his little hole and getting used to the sensation.
“Ah… a little bit,” Jeongguk said airily, rocking his hips now, trying to get Seokjin to slide his finger into his winking pussy. Seokjin was having trouble keeping level-headed, imagining sweet Jeongguk curiously experimenting with his pussy, figuring out how to pleasure himself.
“Okay Jeongguk, relax for me now,” Seokjin said soothingly, running a hand up and down the back of Jeongguk’s thigh as he began to sink his finger into Jeongguk’s virgin hole. Seokjin bit his lip; his little brother’s cunt was so tight and hot, trying to suck him in! “Jeongguk, t-try and loosen up,” he murmured, stilling once his finger was halfway in.
“I’m relaxed, Seokjin-hyung…” Jeongguk mumbled, and Seokjin looked up again at his face, suddenly wanting to weep. His cute little brother was clearing enjoying having his hole played with, his features relaxed and even debauched, eyes unfocused. Then, as if to prove himself, Jeongguk did tighten up, gripping Seokjin’s finger snugly.
Seokjin couldn’t hold back his perverse groan, imagining how Jeongguk’s snug pussy would feel around his—
“Y-You haven’t touched yourself like this recently,” Seokjin said as observationally as he could manage, as if he wasn’t asking his little brother about his masturbation habits.
“Mmm… usually, I just rub my clitty,” Jeongguk moaned, so relaxed and loving it as Seokjin pushed a bit deeper inside. Jeongguk slightly shifted the angle of his hips, inviting Seokjin deeper. “It was hurting inside, but you’re taking it away… it feels so good, Seokjinie-hyung…” He mumbled, closing his eyes and savoring his older brother’s illicit touch.
Seokjin was going to go crazy if his little brother kept talking like that. Keeping his own mouth shut, he pressed inside until Jeongguk’s sensitive rim was stretched around his last knuckle. They both moaned when Jeongguk clenched around him, his wet folds smothering his appendage as if trying to milk something from it.
“Jin-hyung, please, more!” Jeongguk asked desperately, and Seokjin couldn’t deny him. Carefully but perhaps a bit too eagerly, he began fucking Jeongguk’s tight needy hole with his finger, groaning along with his brother.
“Your pussy is so hot and wet inside, Guk-ie…” Seokjin whispered, ashamed of speaking such words but needing to hear them, so they could stoke his arousal. His little brother’s cunt was perfect, would make him cum so hard, and all the while Jeongguk would be begging for it, moaning for his older brother to deflower him and pump him full of seed.
Fuck.
Seokjin knew he needed to stop now. If he truly wanted to be able to justify fingering his half-brother’s underage pussy, there was no way he could take the plunge and fuck him, too. It was so wrong.
The reminder didn’t help Seokjin’s raging lust; it only fueled it further.
“You’re going to, ah, stretch me right, hyung?” Jeongguk nearly slurred, noticing Seokjin’s lack of focus. Seokjin swallowed thickly and nodded, trying not to want as he lined up his thicker middle finger, pressing against Jeongguk’s barely loosened rim.
“Tell me if it hurts,” Seokjin said with a hint of defeat in his voice, pushing his second finger inside. Jeongguk’s lithe body was taking his fingers so well, drawing them in.
“Oh Jin-hyung, mm, feels so good, but I need more…” Jeongguk whimpered, becoming ever bolder with every inch Seokjin gave him. Seokjin pumped his fingers in and out, feeling every soft ridge of Jeongguk’s insides, his wonderfully slippery pussy gripping his digits so hungrily.
“You’re almost ready to… use the dildo,” Seokjin murmured distractedly, completely entranced by Jeongguk’s sopping, greedy cunt. His fingers squelched each time he pushed them in, lewd and loud underneath Jeongguk’s near constant moans.
“No,” Jeongguk whined pitifully, jutting his hips forward, asking Seokjin to press deeper even though his knuckles were nearly swallowed up by his twitching rim. Seokjin wouldn’t be able to go any further unless he pressed four fingers in and could sink half his hand into Jeongguk’s pussy. But there was no way he was ready for that yet.
Instead, Seokjin curled his fingers and stroked them up, stimulating his baby brother’s sensitive clit from inside his pussy. Jeongguk gasped and stilled as Seokjin touched his hot spot, his eyes rolling back when Seokjin pressed mercilessly against the nerves. Seokjin told himself he would give Jeongguk just one amazing orgasm, and then he would call Yoongi and tell him to come here and take care of Jeongguk while Seokjin drove far away.
Because if Seokjin went any further… he would end up taking his brother’s virginity and there would be no going back from that. But at the same time, the reality of the situation set fire to his blood, made him want to indulge himself. Because his sweet little Jeongguk was grinding his pussy against Seokjin’s fingers and begging for more.
Seokjin pumped his fingers in and out, stroking and pressing against Jeongguk’s insides. His little brother was loving it and rocking back and forth so Seokjin could touch more secret places.
“Fuck, Jeongguk,” Seokjin swore, his cock aching, wanting his little brother’s tight pussy to milk his balls dry. He thrusted his fingers faster, truly giving Jeongguk’s cunt the friction it craved. His little clit was straining for Seokjin’s attention, and he bent his head down, rubbing the tip of his tongue underneath the hood.
Jeongguk squealed, his knees instinctively closing around Seokjin’s head. Seokjin was happily trapped, wrapping his lips around Jeongguk’s “clitty” and sucking on it like a peach. His baby brother’s gushing pussy was growing tighter around his fingers as Seokjin tortured his ultra sensitive clit.
“Jin-hyung! Ah…” Jeongguk sounded close to tears, beside himself with pleasure as his hips began to tremble. “Don’t stop, oh… please,” he murmured, and Seokjin shuddered, thinking that he would happily live with his face buried in his little brother’s pussy for the rest of time.
Seokjin worshipped Jeongguk’s sopping pussy, fingering his little hole and pressing hard against his sweet spots, his mouth sucking on his stiff clitty. Jeongguk was truly starting to tremble now, his head thrown back and his eyes squeezed shut, drooly lips parted, a picture of ecstasy.
“’m gonna…” Jeongguk mumbled, his moans starting to staccato, and Seokjin kept up his pace, knowing that this was all his little brother would need. Soon enough, Jeongguk’s jaw dropped in silent ecstasy, his release flooding through him, his hungry little cunt contracting around Seokjin’s fingers, trying to suck seed from them. Seokjin felt tortured, in pleasured agony at the thought of stuffing his aching prick into his brother’s virgin pussy which was so ripe and eager.
Seokjin tenderly pulled his lips away from Jeongguk’s clit, keeping his fingers inside and rocking them gently. Jeongguk was gorgeous spread out before him, totally limp and flushed as the aftershocks of his orgasm resonated through his body, his chest rising and falling sharply as he caught his breath.
Seokjin indulged in the sight for a moment, trying to memorize the feeling of Jeongguk’s perfect cunt squeezing his fingers before remorsefully pulling them out.
“Jin-hyung,” Jeongguk said hoarsely when Seokjin moved away. “Don’t go.”
“Jeongguk, please understand. I can’t… I shouldn’t have—”
“I’ve liked you since the beginning,” Jeongguk interrupted, and Seokjin noticed now that his eyes were clearer after his orgasm, as if his heat had been taken care of. “Jin-hyung, I’ve never wanted anyone like I want you.”
Seokjin rubbed at his eyes, trying not to look at his little brother offering up his young body for him, no shame in how his legs were still spread wide.
“You’re so young, Jeongguk, you don’t know this now but you’ll regret all of this when you’re older,” Seokjin reasoned, turning his back now, patting his pockets for his phone. He needed to call Yoongi and put an end to this.
“That’s insulting, hyung,” Jeongguk replied, suddenly closer to his ear before his arms were wrapped around Seokjin, his chest pressed against Seokjin’s back. “Don’t treat me like a child, I know what I’m asking for.”
“Jeongguk—”
“I know it’s wrong,” Jeongguk insisted again, his arms tightening around Seokjin’s frame. Seokjin let him continue. “I know we shouldn’t do this because we’re half-brothers, because I’m 16 and you’re a bit older. Society will never allow us to exist happily together even if that’s what we both consented to. I don’t care about any of that.”
Jeongguk trailed his hands down to the end of Seokjin’s shirt, sneaking his fingers underneath and raking them up Seokjin’s stomach. Seokjin shivered, all too aware of Jeongguk’s naked body against his back, his perky nipples poking into him.
“Y-You’re in heat right now, you aren’t thinking normally,” Seokjin half-heartedly mustered, Jeongguk’s coherent rebuttal weakening all his defenses. Jeongguk had thought about this before, to a serious extent apparently. He felt the laugh rumbling in Jeongguk’s chest.
“You don’t know this hyung, but I didn’t immediately stop my suppressants all at once. I simply wouldn’t take them on certain days for a while. And on those days where I felt more normal, your scent was so different, so good” he explained, his lips and nose pressed against Seokjin’s nape, inhaling deeply, groaning.
Jin’s face was on fire, his poor balls aching for release at this point. Jeongguk was torturing him so sweetly.
“Sometimes, after you would fall asleep, I would go into your room and…” Jeongguk trailed off in hesitation, rubbing his taut nipples against Seokjin’s back now. Seokjin’s head was spinning.
“What would you do, Jeongguk?” Seokjin prompted, no intention of leaving now, because his wildest fantasies were becoming reality.
“I would t-touch my clitty and c-cunny while standing near your bed, staring at your face,” Jeongguk breathed shyly, but Seokjin could hear the smile in his voice, as if he was pleased with admitting the words. Jeongguk was a pervert, too. “I thought about how you might wake up and pull me into your bed and f-fuck me. I’ve only ever wanted my big brother to play with my cunny….”
Seokjin harbored plenty of self-discipline. But he was only human.
A greedy, lustful human who had been given a minx of a little brother, whose morals were just as skewed.
Jeongguk wanted his older brother to deflower his “cunny” and Seokjin wouldn’t deny him such a thing. Seokjin turned in Jeongguk’s arms, holding Jeongguk’s jaw in his hands and looking seriously into his eyes.
“Are you absolutely sure you want this, Jeongguk?”
“Yes,” Jeongguk nodded, his eyes darting to Seokjin’s lips.
“Tell me to stop if you ever need to, okay?”
“Okay.” And with that, Seokjin sealed his lips to his baby brother’s, relinquishing all pretense of being a caring, good-intentioned person. He wanted to ruin Jeongguk’s purity, to be the first one inside of his baby brother’s untouched pussy.
Jeongguk moaned happily, his lips falling open so easily for his brother, inviting his depravity. Seokjin kissed him deeply, taking all he could get, wanting to touch all of Jeongguk’s private places. It felt so good, so right to be kissing Jeongguk like this, and his little brother seemed to be thinking the same thing, returning his fervor. Overcome with lust, Seokjin pulled away only to unbuckle his belt and push his slacks down his thighs, his cock straining and leaking against his briefs.
Jeongguk grinned and hooked his fingers into his waistband, pulling his underwear down for him, releasing his stiff cock from its confines. Seokjin groaned as he sprung free, feeling absolutely wild at the surprise on his little brother’s face.
“J-Jin-hyung…” Jeongguk murmured, glancing briefly at the forgotten toy laying to the side. Seokjin’s cock was undeniably larger. Instead of being intimidated however, Seokjin’s horny little brother reached out to grip his large cock and stroke it with an excited glimmer in his eyes.
Seokjin nearly shouted at Jeongguk’s sudden touch, the relief like a shock to his system after so much torture. He softened his reaction, biting his lip, feeling like he might burst any moment. Just the context they were in was pushing him close to that edge; his 16-year-old brother was giving Seokjin an inexperienced handjob.
Jeongguk was just as hot and bothered, the blush returning to his cheeks. “I need you to put your cock in my virgin cunny, hyung,” he insisted, touching his swollen clit.
“Jeongguk! Why would you say…” Seokjin trailed off, hissing in pleasure when Jeongguk touched his weeping slit. It was as if Jeongguk was just as perverted at him, loving the taboo just as much as Seokjin.
“I get off on the thought of my older brother taking my virginity,” Jeongguk said cheekily, as if teasing Seokjin, shameless now that Seokjin was obviously at his mercy. Seokjin groaned and had to push his hand away shakily, too close to the edge. He was dreaming. This couldn’t be happening.
“Don’t worry Seokjinie-hyung,” Jeongguk said softly, leaning forward to chastely kiss his brother, mistaking his reaction for guilt. “I promise I know what I’m doing. I’ve wanted you for so long.” He coaxed Seokjin into more open-mouthed kisses, igniting the flame in his blood to an unbearable heat. Jeongguk laid back and dragged Seokjin along with him, who went willingly, tugging off his shirt so that they were naked together.
“I love you, Jeongguk,” Seokjin said sincerely, kissing Jeongguk deeply one last time before moving to position himself between Jeongguk’s spread legs. Just as they were a few moments ago, Jeongguk held his folded legs open for Seokjin’s gaze and now his cock, too.
“I know, Seokjinie-hyung,” Jeongguk sighed happily, smiling eagerly as he watched Seokjin line up his prick with his aching hole. “I love you so much,” he said less coherently as Seokjin shifted his hips, rubbing the head against Jeongguk’s outer folds.
“Are you ready to take my cock Jeongguk?” Seokjin spoke, losing himself, feeling just how tiny Jeongguk’s hole was against the head of his dick. “I don’t know if it will fit into your tight cunny...”
“Oh!” Jeongguk gasped, his eyes widening at Seokjin’s dirty words, his pussy dripping more slick fluid as if in reply. “I-It will fit, Jin-hyung, please make my cunny feel good!” Jeongguk rambled, pressing his hips up. Seokjin rocked his own hips, struggling to be patient, not wanting to hurt his baby brother. He would need to go very slow.
He breached Jeongguk’s little hole with the tip, watching Jeongguk’s face for his reaction. Jeongguk seemed to be in no pain even as Seokjin pushed deeper, the both of them groaning excitedly.
“My b-big brother’s cock is fucking my cunny,” Jeongguk whispered with that naughty smile in his eyes, and Seokjin was totally enraptured, in love with his perverted baby brother.
“Does it feel good, Jeongguk?” Seokjin whispered back, as if conspiring, his hips trembling with the effort of holding back. He was sinking so easily into his brother’s cunt; his walls were so tight but welcoming, sucking him in greedily. “Do you like having your virginity taken by your older brother?”
“Yes!” Jeongguk moaned, his face twisted in apparent pleasure as his underage pussy swallowed up Seokjin’s cock. “Your adult dick feels so good in my naughty cunny~”
“Fuck,” Seokjin swore, his hips stuttering as he bottomed out. Jeongguk was moaning in debauchery, no doubt feeling the stretch in places he’d never been able to reach before. “Where did you learn to talk like that, Jeongguk?” he murmured a bit nervously, wondering if Jeongguk had somehow seen his porn history.
“I’m not a child, Seokjinie-hyung~,” Jeongguk chuckled, rocking his hips and savoring how his cunt had been opened up by his brother’s cock. “I’ve been watching porn for years. And I’ve fantasied about this exact scenario many times…”
“In the eyes of the law, you are a child,” Seokjin reminded him, but this truth didn’t make him pull out, didn’t deter him from deflowering his little brother.
“But the law will never know,” Jeongguk said cheekily, impatiently wiggling now, but Seokjin was holding him steady. “Only I will know that you like fucking your baby brother.”
Seokjin hummed, finally allowing himself to move a bit, rocking his hips and jostling Jeongguk’s body. Fuck, his insides felt absolutely heavenly. Jeongguk’s little pussy was clinging so wetly to his straining cock, it was the perfect sleeve for him.
“And only I will know that you like being fucked by your big brother,” he countered, losing himself in Jeongguk’s perfect, tight cunt. He pulled back further and snapped his hips forward, drawing the prettiest moans from Jeongguk’s lips.
“Yes! F-fuck my naughty cunny, oppa~” Jeongguk whimpered, his mind just as hazy with lust as they gave in to their dark desires. Seokjin groaned at the honorific, fucking his little brother steadily now, shoving his cock into Jeongguk’s needy cunt over and over again. The squelching of their meeting and parting was a rhythmic soundscape, evidence of Jeongguk’s eagerness, his pussy sopping wet.
“You love your oppa’s cock, don’t you, baby bun?” Seokjin nearly growled, frenzied. Fucking his little brother’s pussy was too perfect. He was about to cum and give Jeongguk his first creampie.
“Oppa’s cock is so good! It’s hitting my cunny so deep!” Jeongguk moaned, clutching tightly to Seokjin’s shoulders, pulling him down for a desperate kiss. Their slick bodies slid together, the air thick with their arousal, the sheets damp with their sweat and fluids. Shamelessly, they forced their bodies together in the most decadent of ways.
Seokjin shuddered, feeling close even though he never wanted this moment to end. He knew he needed to make his little brother cum first, work his pussy until Jeongguk was crying in ecstasy. He moved back up, shifting his weight on his knees and gripping Jeongguk’s hips to keep them against the bed. Watching his cock being swallowed up, Seokjin fucked his baby brother’s deflowered cunt vigorously, making sure to pound into Jeongguk’s sweet spot.
“Oppa!” Jeongguk whined, his pussy squeezing Seokjin’s dick hungrily. His little hole was gushing every time Seokjin thrust inside, bathing his big brother’s rigid cock as it prodded his sensitive insides. Seokjin shifted his hips up, mercilessly abusing Jeongguk’s clitty from the inside, the heat of their joining stifling and sinful. Pushing hard against the top wall of Jeongguk’s twitching pussy, Seokjin stuttered in his movements, nearly cumming unexpectedly as he looked down at his little brother.
His flat tummy was shifting just a bit every time Seokjin pressed in, his insides being molded by Seokjin’s large dick.
“Fuck, baby, that doesn’t hurt?” He asked breathlessly, undeniably even more aroused knowing how deep he was fucking his underage brother. He placed his palm on the small bump, feeling it disappear every time he pulled out. Jeongguk was moaning so sweetly, no hint of pain in his voice. Forcing his eyes open, he looked at Seokjin’s hand, seeing the protrusion for himself.
“F-Feels so good~” Jeongguk groaned, his eyes rolling back in his head before slipping closed in bliss once more. “Oppa is, ahh, reshaping my cunny!” he babbled breathlessly, meeting Seokjin’s thrusts now, trying to get him even deeper. Seokjin groaned and held on tight to Jeongguk’s hips, so close, so close—
Jeongguk’s knees were squeezing him tight as he whined,
“Oppa! ‘m gonna pee!” Jeongguk trembled underneath him, trying to move away from Seokjin’s thrusts now. Seokjin bit his lip, needing to hold on just a bit longer.
“It’s okay baby, let it go,” he assured him, moving one of his hands so he could press his thumb against Jeongguk’s stiff little clit, abruptly shoving his baby brother over that edge.
Jeongguk cried out, his little pussy squirting as his orgasm crashed over him, his cunt squeezing Seokjin’s cock so tightly, Seokjin just couldn’t stop himself. Groaning brokenly, Seokjin came inside his little brother’s messy cunt, flooding his womb with semen as Seokjin’s mind blanked out from the pleasure. He’d never known a greater high than cumming inside his baby brother’s just-deflowered pussy.
Fucked out, Seokjin collapsed on top of Jeongguk as slowly as he could manage. Jeongguk didn’t seem to mind, mewling when Seokjin’s cock shifted inside him.
“Don’t pull out,” he mumbled sleepily, and Seokjin’s voice stuttered on a hysterical laugh as he fully realized what he’d done. His mind flashed to the morning after pill Yoongi had given him, and Seokjin flushed deeply. The other hybrid had been right; Seokjin hadn’t been able to resist his sweet little brother.
