Work Text:
The door to dorm room number 7 made a soft click as Namjoon swiped his access card. A double beep greeted him, followed by an unusual silence.
Namjoon let out a long sigh, stretching his stiff neck after spending nearly ten hours in the studio. His final-year Fine Art degree was really draining him of all his energy. He took off his trainers on the genkan, letting his heavy rucksack slump onto the wooden floor.
“Jungkook?” he called softly. His voice sounded a bit hoarse.
Usually, at eight o’clock in the evening like this, the thumping music from the Music Department student’s Bluetooth speaker would already be filling the living room. Or at the very least, a frying pan would be sizzling in the kitchen as Jungkook cooked chicken breast for his diet. But tonight, every corner of the flat felt silent. The kitchen light was off, leaving only the dim glow of the streetlights filtering through the large window in the living room.
Namjoon walked towards the kitchen, intending to fetch a glass of cold water. However, after just three steps, his footsteps suddenly halted.
Something was wrong.
The air in the room wasn’t just cold, it felt… heavy. So thick that Namjoon’s lungs suddenly felt constricted as he tried to breathe. A sharp, woody-musky scent—a mixture of burning cedar wood and the rich aroma of damp earth—assaulted his senses.
The scent of pheromones. The smell of rut.
A chill crept rapidly up the nape of Namjoon’s neck. As a defective Alpha, Namjoon’s pheromone glands had never functioned normally. His pheromones were so faint, almost undetectable, that he was often regarded as nothing more than an ordinary Beta.
But the pheromones currently flooding the corridor of their room were not merely ordinary Alpha pheromones. This was the absolute urge for dominance from a Pure Alpha who was losing his mind.
Jungkook was in rut.
“Jungkook!” Namjoon called out again, this time in a panicked tone. He hurried towards the door of his junior’s room. However, Jungkook’s door stood wide open, and the room inside was completely empty. His bed was neatly made; there was no sign of its owner.
Namjoon furrowed his brow, confused. The scent wasn’t coming from Jungkook’s room.
The intense, piercing aroma that seemed to burn the air was coming from… his own room.
Namjoon’s footsteps halted in front of his own slightly ajar door. Light from the corridor seeped in through the crack in the door, cutting through the darkness inside the room. Namjoon reached out, his fingers trembling slightly as he pushed the wooden door wide open.
And in that very moment, Namjoon froze.
On his bed—on Namjoon’s own bedsheets—a man was curled up on his side.
It was Jungkook. His black sleeveless T-shirt was torn at the collar, revealing his tense shoulders, glistening with sweat. The young Alpha’s breathing sounded heavy and choked, as if every breath he exhaled was burning his own throat.
But what made Namjoon’s blood seem to stop flowing was what Jungkook was doing.
Jungkook wasn’t just lying there. His large, veiny fingers were clutching Namjoon’s worn T-shirt—which had previously been hanging on the back of the study chair—tightly. The garment was pressed almost to the point of suffocation against his face. Jungkook buried his nose and mouth in it, inhaling deeply the linen fabric that still held traces of Namjoon’s scent.
“J-Jungkook…?” Namjoon’s voice escaped as a broken whisper.
Hearing that voice, the figure on the bed suddenly stiffened. Jungkook remained motionless for a few seconds, as if to ensure that the voice wasn’t merely a hallucination from his fever-racked mind.
Slowly, Jungkook pulled Namjoon’s shirt away from his face. The boy’s head lifted slowly.
Namjoon instinctively took half a step back as his eyes met Jungkook’s. Jungkook’s irises, usually a dark brown, now glowed a dim red in the darkness—an unmistakable sign of danger from a Pure Alpha whose primitive hunting instincts were taking over.
“Hyung…” Jungkook’s voice was hoarse, so deep and resonant that it shook Namjoon’s chest.
“Jungkook, you… you’re a rut,” stammered Namjoon, trying to control his voice. “Where’s your suppressant? Why are you in my room?”
Jungkook didn’t answer. He shifted from lying down to sitting on the edge of the bed. His movements were slow, yet radiated a restrained ferocity. Sweat dripped from the edge of his chiselled jawline, falling to dampen Namjoon’s bedsheet.
“Why have you only just come home…?” Jungkook growled softly. He clutched the bedsheet beneath him until the fabric was severely crumpled.
“I had a deadline at the studio,” Namjoon replied softly, still keeping his body pressed against the doorway.
“Jungkook, you need to take your medicine. I’ll get it for you—”
“It doesn’t work,” Jungkook cut in sharply. His breathing was ragged, his chest rising and falling erratically. “The medicine… it’s completely useless, hyung.”
Namjoon furrowed his brow. “Your high-dose suppressant—”
“I’ve already taken three doses!” Jungkook cut in again, this time in a low, explosive voice. The growl sent a shiver down Namjoon’s spine. Jungkook clenched his fists on his knees, trying to steady the tremors in his own body. “I’ve taken three doses since this afternoon, but none of them are working! My head’s about to explode...”
Namjoon swallowed hard. This situation made absolutely no sense. A Pure Alpha did indeed have a high resistance to pheromone suppressants, but three doses should have been enough to suppress their instincts for several hours.
“Then… why are you on my bed?” Namjoon asked softly, trying to keep his voice as calm as possible so as not to provoke the Alpha’s aggression. “Why are you holding my shirt?”
Jungkook looked up. His sharp, red eyes were fixed intently on Namjoon. He lifted Namjoon’s shirt, which he was clutching, holding it up slightly in the air.
“This,” whispered Jungkook, his voice trembling as he held back his overwhelming frustration. “This is what’s driving me mad.”
“What do you mean…?”
“Your scent, hyung,” replied Jungkook innocently, though it sounded painful.
Jungkook stood up.
Namjoon was taller than Jungkook, but facing a pure alpha in heat made Namjoon feel small. Namjoon reflexively took another step back, but his back suddenly hit the doorframe. He was trapped.
Jungkook stepped closer. Every step he took was accompanied by a wave of woody-musk pheromones that grew denser and denser, until they were intoxicating. The scent of damp earth and burning wood now enveloped Namjoon’s entire body, seeping into the pores of his skin.
Jungkook stopped right in front of Namjoon. They were no more than ten centimetres apart. Jungkook’s body heat radiated intensely, like a grill scorching the cold air between them.
“…the scent of you on this shirt is driving me mad.”
Namjoon held his breath. His eyes widened. “Jungkook, that… that’s impossible. I’m a defective alpha. My pheromones—”
“Namjoonie-hyung, your pheromones aren’t defective,” Jungkook interjected softly. His large hand rose, his warm, trembling fingers touching Namjoon’s jaw with a gentleness that contrasted with his wild eyes.
“Your pheromones are just too subtle to be understood.” The touch on his jaw sent a shiver down Namjoon’s spine. Strangely, instead of feeling threatened like other Alphas whose pheromones were challenged, Namjoon’s body reacted in the opposite way. His throat felt dry, and the pheromone glands at the back of his neck—which for years had been considered dormant—suddenly began to pulse with warmth.
A faint, sweet scent of cinnamon and vanilla—Namjoon’s hidden pheromones—began to seep out beyond his control.
Jungkook’s pupils dilated further as he detected that subtle scent emanating directly from its source. Jungkook’s thumb traced Namjoon’s jawline, pressing gently near the pulse in his neck.
“See…?” whispered Jungkook right in front of Namjoon’s face, his hot breath brushing against Namjoon’s lips. “You’re the one who led me on.”
“Jungkook… stop,” whispered Namjoon weakly, yet the surge of the Pure Alpha’s pheromones before him made his knees feel weak. “We’re both Alphas.”
“I don’t care what you say,” Jungkook growled lowly. His other hand crept down, gripping Namjoon’s waist and pulling the taller yet slimmer body tightly against his chest.
Namjoon drew a sharp breath as their bodies collided. He could feel Jungkook’s heart pounding fiercely against his chest, as well as the absolute tension in the young Alpha’s body, which was currently in the grip of the rut.
Jungkook lowered his head, pressing his nose against the crook of Namjoon’s neck, inhaling that faint, sweet scent deeply until his breath sent shivers down Namjoon’s neck.
“Namjoon-hyung…” Jungkook hissed against his neck, his Alpha growl sounding so absolute, demanding surrender. “Please help me…”
Flashback
The pungent smell of cheap pine-scented floor cleaner still stung his nostrils when Jungkook first set foot in dorm number 7.
As a first-year student in the Music Department who’d gained entry through a full merit scholarship, Jungkook was already accustomed to high expectations and the hesitant stares of those around him. His status as a Pure Alpha—a rare mutation with absolute genetic dominance—meant his presence was always the centre of attention as well as a veiled threat to others. Wherever Jungkook was, the atmosphere always felt tense.
Jungkook hated that situation. He hated the fact that his body constantly emitted such an overpowering scent of woody-musk pheromones that it made those around him feel as though they were running out of oxygen.
Therefore, when the university hall of residence management informed him that he would be sharing a room with a senior student from the Fine Art Department, Jungkook was already bracing himself for the worst-case scenario: cold stares, veiled hostility, or a request to change rooms within less than a week.
However, those realistic expectations were shattered the very moment he opened the door.
The living room of dorm number 7 looked in disarray, with piles of sketchbooks, blank canvases leaning against the wall, and rolls of tracing paper scattered across the wooden table. Amidst this creative chaos, a tall man was kneeling on the floor, his fingers smeared with cobalt blue and black oil paint.
The man turned his head when he heard the door open. Thick black-rimmed glasses sat slightly askew on the bridge of his nose.
“Ah, you must be Jungkook, right?” The man stood up, wiping his dirty hands on his jeans—already covered in old paint stains—then held out his hand with a broad smile. Two deep dimples formed on either side of his cheeks, softening the sharp impression of his high jawline.
“I’m Kim Namjoon. Fine Arts student. Welcome to dorm number seven,” he continued with a chuckle, showing absolutely no sign of being intimidated.
Jungkook froze in the doorway. His hand was still clutching the strap of his rucksack tightly. The first thing Jungkook noticed wasn’t the man’s friendliness, but the atmosphere around Namjoon, which was strangely… empty.
Instinctively, the Alpha within Jungkook always kept his pheromone sensors on high alert to detect threats when encountering another Alpha. However, when his eyes met Namjoon’s, his inner instincts didn’t react at all. The air around Namjoon was so clear, devoid of any aura of dominance or the waft of pheromones usually emitted by other Alphas to mark their territory.
“Jeon Jungkook, Music Department,” Jungkook said softly, accepting the outstretched hand hesitantly.
The sensation of their skin touching felt strange to Jungkook. There was no instinctive jolt of rejection, no defensive tremor. Namjoon’s hand was warm, calloused in places from carving and painting, yet his grip was very friendly.
“Sorry it’s a bit of a mess,” said Namjoon casually, pulling his hand back and then pointing down the corridor with a smear of paint on his thumb. “Your room’s on the left. I cleaned it yesterday, but if you want to rearrange it, it’s up to you. Oh, and if you need anything, just let me know,”
Jungkook merely nodded stiffly, following Namjoon as he strolled casually towards the kitchen to make a cup of coffee.
The first few days of living together passed in an awkward silence for Jungkook. As a Pure Alpha, Jungkook was used to taking a high dose of suppressant every morning to suppress his dominant pheromones so they wouldn’t cause panic on campus. As a side effect, Jungkook often felt exhausted and easily frustrated.
However, inside dorm number 7, that tension gradually eased. Jungkook gradually learnt the rumours about his dorm mate from the other students. Kim Namjoon was a defective Alpha—a rare medical condition where a person’s pheromone glands do not develop fully from puberty onwards. Namjoon lacked a strong signature scent, could not emit an intimidation scent, and was regarded by the majority of students as a ‘failed’ Alpha who was nothing more than a Beta with a tall build.
Jungkook often heard those mocking whispers in the campus canteen. Defective Alpha, useless, boring.
But to Jungkook, Namjoon was the only oasis amidst the stifling campus environment. For the first time in his life, Jungkook could return to a place where he didn’t have to worry that his dominant pheromones would hurt or oppress others.
Namjoon never trembled when Jungkook accidentally released his pheromones whilst tired. Namjoon never looked at Jungkook with a wary gaze.
To Namjoon, Jungkook was just a burly junior who loved eating chicken breast and practising his vocals late into the night.
“Kook, have you been taking your suppressant again?”
Namjoon’s voice snapped Jungkook out of his reverie one evening in their third month of living together. It was pouring with rain that day, and Jungkook was sitting on the living room sofa, massaging his throbbing temples. The side effects of the double-dose pheromone suppressant he’d taken that morning were beginning to take hold.
Namjoon walked over, carrying a glass of warm water, and placed it on the coffee table in front of Jungkook.
“I saw your medicine bottle in the bathroom. The dose is too high for someone your age, Kook,” Namjoon said softly. He sat down on the edge of the same sofa, looking at Jungkook with a worried expression.
Jungkook rubbed his pale face. “I’m a Pure Alpha, hyung. If I don’t take this dose, the people in the music faculty might get disturbed when I’m practising.”
Namjoon let out a long sigh. He leaned back, staring at the slightly peeling ceiling of the dorm. “It’s a pain, isn’t it, being ‘too perfect’?”
Jungkook chuckled cynically. “Better than being called defective, right?”
The words just slipped out of Jungkook’s mouth without him thinking. The very next second, Jungkook immediately cursed his own stupidity. He turned quickly towards Namjoon, panicking that his words might have hurt his senior’s pride.
“Hyung, I’m sorry… I didn’t mean to—”
Namjoon, however, laughed softly. A low, warm laugh that vibrated comfortably in his chest. “Why apologise? That’s the truth, isn’t it? My pheromone glands have been faulty since secondary school. The doctor said my scent barely comes through at all, like the lingering fragrance of a bar of soap that’s almost finished. That’s why other Alphas often look down on me.”
Namjoon turned, looking Jungkook straight in the eye. His serene eyes radiated absolute acceptance of himself.
“But here, you don’t need to torture yourself with those toxic drugs, Jungkook-ah,” Namjoon continued in a soft yet firm voice. “This is your home too. If you’re tired from being out and about, just let your pheromones flow in the dorm. I won’t be affected. Just think of my faulty glands as a bonus perk for you, okay?”
Jungkook was transfixed.
That night, for the first time, Jungkook let his Pure Alpha pheromones flow freely through the living room. The rich, woody-musky scent rose high, filling every corner of the room. If it had been an ordinary Alpha, they would surely have cowered in fear or challenged him to a fight.
But Namjoon just sat there, sipping his coffee with a small smile, rubbing his neck which was slightly itchy from the sudden exposure to the thick air.
“Hmm… people are right. You smell like a burnt-out cedar forest,” Namjoon murmured casually as he continued reading his book. “But it’s not bad, actually—it’s quite warming on a rainy day like this.”
Jungkook watched Namjoon from the side. And in that very moment, the deepest instinct behind Jungkook’s Pure Alpha soul suddenly shifted.
Jungkook realised something that no doctor or any of the fools at their university knew. Namjoon’s pheromones hadn’t disappeared. The scent had never been flawed.
When Namjoon was relaxed and very close to him, there was a very faint scent—so hidden and subtle—seeping out from the crease of Namjoon’s neck. A sweet, cinnamon-vanilla scent that was extremely rare, unlike typical Alpha pheromones. The scent was so delicate that it could only be detected by the nose of a Pure Alpha whose sense of smell was at its peak.
The scent wasn’t intimidating. It wasn’t aggressive. But that faint scent of Namjoon’s acted like the most dangerous drug for Jungkook.
Ever since that night, Jungkook had realised it. Whenever Namjoon went to university, Jungkook would quietly slip into Namjoon’s room, stand near his wardrobe, and inhale the lingering traces of that sweet scent. The more Namjoon behaved like a protective, unfazed older brother, the stronger Jungkook’s hidden urge to mark him became.
Namjoon thought he was safe because he felt ‘flawed’.
Namjoon never realised that the very absence of any threat from his pheromones actually made him the only, most perfect prey ever desired by a Pure Alpha like Jungkook.
End of flashback
In a dark, stuffy room, heavy with the scent of rust.
Jungkook clutched Namjoon’s waist ever tighter, burying his face in the warm neck of the man who was now trembling in his embrace. Memories from three years ago spun rapidly through his mind, clashing with the wild instincts that were now consuming his common sense.
“I’ve been holding this in for years, hyung…” Jungkook whispered hoarsely into the crook of Namjoon’s neck, his breath ragged and hot. “I thought I could hold on. But your scent on these sheets… it’s made me realise I’ve never just wanted to be your junior.”
Namjoon’s mind felt as though it were being battered by a storm. His brain, usually filled with art theory and logical analysis, was suddenly completely paralysed. All the secondary school biology textbooks he’d ever read since secondary school crumbled instantly under the grip of Jungkook’s hands, which were burning against his waist.
How could this be…?
Naturally, the Alpha Law of Nature is about dominance and territory. When two Alpha pheromones clash in the same room, the expected biological response is ‘fight or flight’—a mutual threat that triggers an adrenaline surge, an urge to subdue one another, or a bloody brawl until one gives in. An Alpha is never aroused by another Alpha. That is an absolute law written in every medical textbook.
“J-Jungkook… wait,” Namjoon’s voice choked, almost pleading, as Jungkook’s large palm crept higher, slipping beneath the thin T-shirt he was wearing. The heat of Jungkook’s fingers touched Namjoon’s bare waist, causing the taller boy’s body to flinch in surprise.
“This doesn’t make any sense…” Namjoon whispered, trying to gather what remained of his sanity. His trembling hands pushed against Jungkook’s broad shoulders, trying to create some distance, though his efforts were in vain as Jungkook’s embrace was like an iron grip. “We’re both Alphas, Jungkook! If two Alphas are close together during the rut, we should… we should be attacking each other! Not… not like this!”
Jungkook gave a low chuckle. That hoarse laugh, perched right by Namjoon’s ear, sent an electric shock down his spine.
“Attack each other?” Jungkook hissed. His nose gently brushed against Namjoon’s jawline, inhaling deeply the scent of cinnamon and vanilla that now flooded the air even more intensely due to the panic. “Are you challenging me, Hyung? Do you want to fight me right now?”
Jungkook pulled his head back slightly; his dim red irises grew darker, glinting with a pure and dangerous instinct of possession. There was not the slightest hint of hostility there. There was only an unbearable thirst.
“Look me in the eyes, hyung,” Jungkook commanded in a low voice, his tone carrying the Alpha Voice—an absolute frequency that demanded obedience. “Do I look like I’m about to hit you? Do I look like I see you as a threat?”
Namjoon swallowed hard. His tongue felt heavy. He saw no competitive threat. What he saw in his junior’s eyes was the gaze of a predator who had finally found his most prized prey after years of starvation.
“Normal biological systems only apply to ordinary Alphas, hyung,” whispered Jungkook, his thumb stroking Namjoon’s lower lip, which was trembling slightly. “They can only respond to Omeotic pheromones because their bodies are shallow. But I’m a Pure Alpha. And Namjoon-hyung...”
Jungkook lowered his head, pressing his lips against Namjoon’s neck—right above the pheromone gland that had long been thought to be dormant. Namjoon let out a soft gasp, his body going completely rigid as Jungkook’s hot lips sucked on the smooth skin there.
“…You’re not a defective alpha like those idiots say,” Jungkook continued, his lips resting on Namjoon’s neck. “Your gland isn’t damaged. It’s just locked. This scent of cinnamon… it’s not an aggressive pheromone.”
“N-no… you’re just hallucinating because your rut is too severe, Jungkook!” Namjoon tried to grab Jungkook’s upper arm, intending to twist his body free. “The drug’s effects must be messing with your mind. Let me go, so I can get—”
In a lightning-fast movement that Namjoon’s reflexes couldn’t anticipate, Jungkook reversed their positions. Namjoon’s back was gently flung onto his own foam mattress, and before he could get up, Jungkook’s large body was already pinning him down from above. Namjoon’s hands were pinned tightly above his head by Jungkook’s single, powerful grip.
“Jungkook!” Namjoon cried out in panic. His chest rose and fell rapidly.
The atmosphere in the room had now completely changed. The air around them was filled with a blend of two contrasting yet perfectly harmonious scents: Jungkook’s dominant, rich woody-musk, tightly enveloping Namjoon’s cinnamon-vanilla scent, which was becoming increasingly pronounced due to biological urges.
The fight Namjoon had feared did not happen at all. Namjoon’s body—which should have resisted the dominance of another Alpha—instead responded in a way that completely defied his own logic.
His muscles went limp. The pheromone glands in his neck suddenly throbbed violently, pumping a heat he’d never felt in his entire life, surging towards his groin.
Namjoon groaned softly, closing his eyes tightly as the unfamiliar warmth began to burn the lower half of his body.
“It can’t be…” Namjoon cried inwardly. Was he aroused? By another Alpha’s pheromones?!
“You can feel it, can’t you?” Jungkook teased in a low voice. He leaned down, pressing their foreheads together. Jungkook’s ragged breaths brushed against Namjoon’s face, which was now flushed a deep crimson.
“Your glands are responding to me, hyung. We’ll never fight, hyung… because from the very beginning, our bodies were made to complement each other.”
“This is wrong…” Namjoon whispered, tears of frustration nearly spilling from the corners of his eyes. “If the students at uni find out… if people find out…”
“No one will find out,” Jungkook cut in quickly. He released his grip on Namjoon’s wrist, then slipped his fingers between Namjoon’s, intertwining them tightly on top of the pillow. “I won’t let anyone touch or smell this scent except me. Namjoon hyung is mine alone. These pheromones are just for me.”
Jungkook lowered his head again, this time brushing Namjoon’s lips with his own. That first kiss felt demanding, hot, and steeped in the pure dominance of a Pure Alpha at the height of his power.
Namjoon’s mouth opened reflexively, letting out a soft moan within the kiss. Jungkook seized the opportunity to deepen the kiss, devouring Namjoon’s upper and lower lips with a ferocity that had been pent up for three years.
His tongue forced its way in, exploring every corner of Namjoon’s mouth, savouring the sweet taste that felt like heaven amidst his daily torment.
Their grip on each other tightened. Namjoon tilted his head back, surrendering as Jungkook’s tongue entwined with his own. His mind, which had been filled with scientific questions, was now completely empty, replaced by a burning sensation coursing through his nerves.
When Jungkook finally pulled away to let Namjoon catch his breath, a thin thread of saliva connected them. Namjoon was panting; his eyes, which had been closed, now opened languidly, gazing at Jungkook’s face, which was so close above him.
“I want you, hyung,” Jungkook called hoarsely, looking straight into Namjoon’s soul. “Please… give me what I’ve needed for the past three years, hyung.”
Namjoon could no longer find the words to reply. His understanding of the Alpha world had completely crumbled tonight, leaving only his body’s most basic instincts, which were now entirely at the mercy of the Pure Alpha lying on top of him.
“You’ve got to prepare me properly.”
Namjoon’s face felt as though it were on fire. The words that had just slipped from his lips sounded so unfamiliar, as if they’d been spoken by someone else. Namjoon—a Fine Arts student who’d always relied on logic and self-control—was now completely surrendering the last remnants of his defences in the presence of a Pure Alpha raging with rut.
However, hearing those words come from Namjoon’s mouth caused Jungkook’s gaze to tremble violently.
Jungkook’s retinas, which had been glowing a faint red, instantly darkened, radiating a satisfaction that was both pure and dangerous. Namjoon’s words were not merely permission; to the Pure Alpha instincts within Jungkook, that sentence was the ultimate surrender of power. The prey had chosen to give himself up willingly.
“You… heard that, didn’t you?” Namjoon whispered again, hiding his flushed face by turning his head to the side. His hand, which had been clutching Jungkook’s shoulder, now gripped the bedsheet beneath him tightly.
“Don’t rush… if you don’t prepare me properly, I’ll hate you, Jungkook-ah.”
Jungkook gave a low chuckle. The growl in his voice, heavy with possessiveness, sent shivers through Namjoon’s chest, which was pressed tightly against his own.
“I won’t, hyung,” Jungkook hissed hoarsely. He lowered his head, kissing Namjoon’s tense jawline with a tenderness that stood in stark contrast to his burning, dominant aura.
“I’ll get you ready… until you’re the one begging me to come inside.” Jungkook shifted his weight, kneeling between Namjoon’s long legs. His large hands crept down to Namjoon’s waist, pulling the thin T-shirt his senior was wearing over his head and flinging it carelessly onto the floor.
Namjoon held his breath as the room’s cool air touched his bare chest. But the chill lasted only a second, before Jungkook’s body heat enveloped him once more.Jungkook gazed at Namjoon’s body beneath him. Namjoon’s tall, well-proportioned frame, with the smooth, Alpha-like muscles, still looked so beautiful to him.
What’s more, the pheromone glands on Namjoon’s neck were now pulsing incessantly, pumping out an increasingly intense, sweet scent of cinnamon and vanilla that made Jungkook’s head spin with desire.
“So beautiful…” Jungkook murmured innocently, yet with a wild intensity.
Jungkook lowered his head, showering Namjoon’s chest with passionate kisses. His mouth nipped at the smooth skin there, leaving a purplish-red mark near Namjoon’s collarbone—the first mark of possession he had consciously left. Namjoon moaned softly, his fingers creeping upwards and slipping into the strands of Jungkook’s black hair, damp with sweat, clutching it tightly.
“Ah… J-Jungkook…”
The sensation of that touch jolted Namjoon’s nerves so swiftly. The Pure Alpha pheromones filling the air acted as an invisible lubricant for Namjoon’s nervous system, making his entire skin hundreds of times more sensitive than usual.
Jungkook moved further down. His hand slid towards the cargo trousers Namjoon was wearing, unbuttoning them with a deft movement before pulling them down along with his underwear.
Now Namjoon was completely naked beneath Jungkook’s hold. A sudden wave of shame washed over Namjoon like a tidal wave. He reflexively tried to cross his long legs to cover his cock, but Jungkook’s large hands easily held Namjoon’s knees, gently but firmly pulling them apart again.
“Don’t cover it up, hyung,” Jungkook whispered softly, gazing directly into Namjoon’s teary eyes, which were brimming with overwhelm. “Look at me. Let me see everything.”
Jungkook reached for a bottle of moisturising lotion that happened to be on the bedside table next to Namjoon’s bed. Without hesitation, he poured a generous amount of the cool liquid onto his own palm.
The moment Jungkook’s palm, coated in the cool liquid, touched Namjoon’s inner thigh, Namjoon’s body jerked in surprise. “J-Jungkook, it’s cold—”
“Sshh… it’ll be warm in a moment, hyung,” Jungkook interrupted softly.
Jungkook began massaging Namjoon’s inner thigh, spreading the liquid whilst continuing to breathe his warm breath onto Namjoon’s stomach. The touch of Jungkook’s veiny, warm fingers slowly eroded the cold, replacing it with an increasingly intense burning sensation in Namjoon’s groin area.
Slowly, one of Jungkook’s fingers slid closer to Namjoon’s hole. When the fingertip touched the sensitive spot there, Namjoon gasped in surprise, his back arching high off the mattress. “Nhh…! Jungkook!”
“Relax, Namjoonie-hyung… breathe,” Jungkook whispered softly. He leaned down, kissing Namjoon’s lips again to distract his senior from his fear and tension. At the same time, his finger began to push in slowly.
Namjoon’s body felt incredibly tight and hot. As a fellow Alpha who had never been prepared for a situation like this, Namjoon’s muscles clenched reflexively, resisting the foreign object trying to force its way in.
Jungkook didn’t force the issue. He held his finger inside, allowing Namjoon’s body to adapt to its size. Whilst waiting, Jungkook let his woody-musk pheromones completely envelop Namjoon, calming his senior’s defensive instincts until, little by little, the tension in Namjoon’s body eased. A sweet, faint scent of cinnamon wafted once more from Namjoon’s neck, signalling that his body was beginning to accept Jungkook’s dominance.
Good job…” Jungkook praised hoarsely, his lips barely touching Namjoon’s. His finger began to move—in and out with a slow but steady rhythm, massaging the warm walls inside to stretch them.
“Nhh… aaah…” Namjoon moaned softly, his head shaking from side to side on the pillow. The unfamiliar sensation that had once been frightening had now turned into a pleasurable throbbing he’d never imagined before. “J-Jungkook… it feels… strange…”
“It’s not strange, hyung… it’s just that your body isn’t used to it yet,” whispered Jungkook.
Jungkook added a second finger, then a third. His movements grew deeper and wider, preparing the way for his Pure Alpha size. Every time Jungkook’s fingers brushed against a sensitive spot inside, Namjoon would let out a low moan and clench Jungkook’s broad shoulders until the knuckles turned white.
Sweat was pouring down Jungkook’s forehead. Restraining himself from penetrating Namjoon straight away whilst he was at the height of his arousal was the most gruelling ordeal he’d ever endured. The primal roar in his head kept screaming, urging him to mark and claim Namjoon at once. But seeing Namjoon lying submissively beneath him, struggling to breathe and accepting every touch, made Jungkook hold back with all his might so as not to hurt the man he loved.
After ensuring Namjoon’s hole was fully relaxed and lubricated with lotion, Jungkook withdrew his three fingers.
The soft sound of the lubricant slipping out made Namjoon’s face flush even more. Namjoon opened his heavy, lust-clouded eyes and gazed at Jungkook, who was now positioning his cock right between his thighs.
Jungkook’s hard, veiny cock was now pressing gently against the rim of Namjoon’s hole. The sheer size of Jungkook’s Pure Alpha was truly intimidating, causing Namjoon to swallow hard as he realised it.
“Hyung…” Jungkook’s voice echoed deeply, his red eyes glowing brightly in the darkness of the room. “I can’t hold back any longer.”
Namjoon wrapped both his arms around Jungkook’s neck, pulling his younger brother’s head down until there was no gap between their faces.
“Do it… Jungkook-ah,” Namjoon whispered, surrendering complete control to the Pure Alpha’s instincts. “Claim me.”
The moment the tip of Jungkook’s cock pressed gently against the hole, Namjoon instantly realised that all the preparation so far had been nothing. The size of a Pure Alpha when in rut was truly on a completely different level—far exceeding the fingers that had just loosened him up.
“J-Jungkook… gently…” Namjoon whispered, his voice catching. His eyes widened, gasping for air as the massive, filling sensation began to push its way in.
Jungkook held his own breath, growling low against the nape of Namjoon’s neck. The muscles of his back, damp with sweat, tensed rigidly, trying to hold back the urge of his wild instincts from striking with full force straight away. His large hand crept downwards, slipping his fingers beneath Namjoon’s long thigh to lift it slightly, providing a smoother angle of entry.
"Breathe, hyung... please," Jungkook’s voice was hoarse, trembling as he endured the incredible, blissful torment whilst Namjoon’s hot, incredibly tight Namjoon's hole began to envelop his cock. "Don’t tense up..."
Slowly, inch by inch, Jungkook pushed his hips forward.
"Aah! S-stop—Nhh...!" Namjoon let out a shrill scream, his head thrown back as far as it would go until the veins in his neck stood out sharply.
Namjoon’s body, that of an Alpha, reflexively tried to resist the massive size forcing its way into a place he’d never imagined before. The sensation was so intense, stretching him to his absolute limit that it felt as though his entire pelvis was on fire. It felt too big, too full, to the point where Namjoon’s lungs felt as though they had no room to expand.
Yet at the same time, that intense pain and stretching mingled with an intoxicating biological satisfaction. With every inch of Jungkook’s cock that crept inside, the pheromone glands in Namjoon’s neck erupted even more fiercely, pumping out an increasingly rich and sweet scent of cinnamon and vanilla.
“J-Jungkook. Sshh… it’s too big…” Namjoon moaned, tears of agonising pleasure finally trickling from the corners of his eyes, dampening the pillow beneath him. His hands clenched Jungkook’s broad shoulders until they turned red, his fingernails almost digging into the flesh.
“You’re doing really well, hyung,” Jungkook murmured against Namjoon’s lips.
Jungkook leaned down, devouring Namjoon’s lips with a deep, rough kiss, drawing Namjoon’s moans and breaths into his own mouth to distract him from the dizziness caused by the tightness squeezing him. Jungkook’s hips thrust forward again—this time deeper—until finally the tip of his cock slammed tightly against Namjoon’s inner.
Their hips collided perfectly. Jungkook was completely immersed within Namjoon’s body.
“Nhhhhhh—!” Namjoon let out a stifled cry amidst their kiss, his entire body trembling violently from head to toe. The sensation of being completely filled by a Pure Alpha sent a massive electric shock that paralysed all his rational faculties. His mind, usually filled with art, was now completely blank, consumed by an extreme pleasure he had never felt in his entire life.
Jungkook froze on top of Namjoon’s body for a few seconds, letting his chest rise and fall rapidly. It felt like being in a burning paradise. Namjoon’s hole was so warm, wet, and clamped down on his cock so tightly as if it had no intention of letting Jungkook go again.
“Crazy… Namjoonie-hyung… this is crazy…” Jungkook hissed hoarsely, burying his face in Namjoon’s neck whilst inhaling the scent of cinnamon that now completely enveloped them. “Hyung… it’s so tight…”
“J-Jungkook… d-don’t move just yet…” Namjoon pleaded in a voice that was completely broken and hoarse. His fingers were still clutching Jungkook’s muscular back. “Full… so full…”
“Sorry, hyung… but I can’t wait any longer,” Jungkook whispered softly.
The surge of primal instinct in Jungkook’s head could no longer be suppressed once he felt the warmth inside his senior’s hole. Without waiting any longer, Jungkook slowly pulled his hips back—causing Namjoon to groan softly at the sudden sensation of emptiness before finally thrusting back inside with a sharp, powerful stroke.
Namjoon let out a loud gasp, his eyes rolling back as the tip of Jungkook’s penis struck the very spot that was most sensitive within his warm walls. A deadly wave of pleasure instantly shot down his spine, causing his lower abdomen to twist violently.
“J-Jungkook! Right there—Nhh! Ah!”
Jungkook, realising the intense reaction from Namjoon’s body, immediately locked onto that spot as his primary target. A wild, faint smile appeared on the Pure Alpha’s lips. With a slow yet devastating rhythm, Jungkook began to thrust his hips. In and out, always pounding that sensitive spot with intoxicating precision.
The sound of their skin—damp with sweat and lubricant—clashing echoed loudly in the dark room. Every time Jungkook thrust in, Namjoon could only arch his body on the bed, screaming his name amidst unbroken moans.
“Jungkook… ah! S-slow down… Nhh! Jungkook!”
“I can’t, hyung… You feel so good,” Jungkook growled, his fiery red eyes growing dimmer with pure passion.
Jungkook quickened the pace of his thrusts. The tenderness he’d shown earlier was slowly eroded by the ferocity of the Pure Alpha staking his claim. Jungkook’s large hands seized Namjoon’s wrists, pressing them firmly into the pillow beside his head, whilst his hips continued to pound mercilessly from below.
“Ah! Ah! J-Jungkook… I… I want to c-come… Nhh!” Namjoon babbled incoherently. The part of his body that hadn’t been touched at all was now tensing violently, dripping with pre-cum due to the extraordinary stimulation from within his body.
“Come for me, hyung…” Jungkook whispered hoarsely, leaning down to suck on Namjoon’s nipple, which was rising and falling dramatically. Namjoon screamed even louder with pleasure because of it.
Jungkook ramped up the tempo to its highest level. His thrusts were now deeper, rougher, and more frantic, as if he wanted to bury himself as deeply as possible inside his senior’s body. Namjoon was completely submerged in a sea of sensations—a mixture of the tightness caused by Jungkook’s overwhelming size and the unparalleled pleasure that shattered all his pride as an Alpha.
“Jungkook! Aghh— Jungkook!”
With one final, deepest thrust that pounded the very depths of his passage, Namjoon reached his climax without being touched. His warm fluid gushed forth, drenching his own stomach and chest as his body convulsed violently beneath Jungkook’s grip. His hole clamped down on Jungkook’s cock so tightly that it made the Pure Alpha writhe in ecstasy.
"Nghhh... Namjoon-hyung...!"
Jungkook growled lowly like a victorious wild beast. Feeling the tight grip of Namjoon’s hole as he came, Jungkook thrust three more times—quickly and deeply—before finally pressing his hips tightly against Namjoon’s and releasing a massive load of warm semen, flooding Namjoon’s hole.
The room suddenly fell silent, broken only by the ragged breathing of the two men pressed tightly together on the dishevelled bed.
Namjoon lay limp, his eyes half-closed as he gasped for breath. His body felt so warm, filled with the semen and dominant pheromones of the Pure Alpha now lying on top of him.
Jungkook didn’t pull out straight away. He remained buried deep within Namjoon’s warmth, lowering his head to kiss his senior’s sweat-dampened temple with a tenderness that had returned.
“Thanks, hyung…” Jungkook whispered hoarsely into Namjoon’s ear. “You’ve only got me now.”
Namjoon paid no heed to that clichéd possessive remark, “Again… Fuck me harder.”
The silence that had hung in the air of room number 7 was instantly shattered into a thousand pieces.
Jungkook, who had been preparing to pull out slowly—intending to give his senior a moment to catch his breath—suddenly froze completely.
His red eyes, which had begun to dim, flared sharply once more, glinting with both shock and a hunger that had surged a hundred times more ferocious.
Namjoon’s hoarse, deep voice, brimming with defiant resignation, acted like pure petrol poured directly onto the raging fire of a Pure Alpha’s lust.
“Hyung…” Jungkook hissed hoarsely, his hot breath striking Namjoon’s swollen, wet lips directly. “Namjoon-hyung, do you realise what you’ve just said?”
Namjoon didn’t respond with sweet words. Instead, his tall, trembling thighs wrapped tightly around Jungkook’s sturdy waist, pulling the younger Alpha’s body even closer into him. Namjoon’s eyes, watery and clouded with passion, stared directly into Jungkook’s red retinas—without a trace of fear, without a shred of doubt.
Namjoon’s cinnamon-vanilla pheromones, which had been faint, now bloomed fully. The glands in his neck pumped out that sweet scent uncontrollably, inviting, enticing, and surrendering his entire territory to be plundered by the Pure Alpha.
“I’m telling you… again, Jeon Jungkook,” Namjoon called hoarsely, his fingers clenching tightly around Jungkook’s shoulder muscles until his fingernails turned white. “Do it harder… fuck me harder.”
“Trust me, hyung… You won’t be able to back out after this,” Jungkook growled softly.
The roar of the Pure Alpha’s instinct within Jungkook’s head erupted in full force. The patience and gentleness he had been striving to maintain all this time crumbled without a trace. Jungkook cupped Namjoon’s jaw with his large hand, kissing his senior’s lips ferociously. The kiss was hot, rough and demanding—sucking Namjoon’s moans deep into his own throat.
Without breaking their lip-to-lip connection, Jungkook pulled his hips back until only the tip of his cock remained at the entrance to Namjoon’s hole, before finally a powerful thrust slammed in, pounding the depths of Namjoon’s passage mercilessly.
“Nhhh—!”
Namjoon let out a shrill scream into Jungkook’s mouth, his eyes wide as a far more destructive sense of fullness stretched him to his absolute limit. His back arched high off the mattress, every joint trembling violently as he endured the wild thrusts that seared his central nervous system.
Jungkook didn’t give him a single second’s respite. As soon as the tip of his cock slammed tightly against Namjoon’s prostate, he immediately pulled it out and thrust it back in with a frenzied rhythm.
Jungkook broke off the kiss, leaving a thread of saliva connecting their lips.
The sound of wet, heavy flesh slapping echoed loudly throughout the room. Namjoon’s wooden bed creaked loudly under the weight of the two Alpha bodies colliding in overflowing passion.
“Ah! Ah! J-Jungkook! Nhh… f-fuck…!” Namjoon babbled incoherently, his head shaking wildly on the pillow already damp with sweat.
Every time Jungkook thrust in with an ever-faster and deeper rhythm, the tip of that massive cock always struck Namjoon’s prostate with devastating precision. An overwhelming sensation of pleasure engulfed Namjoon’s entire pelvis, completely burning away his logic as an Alpha. The tall man had now completely surrendered himself, allowing his body to be violently shaken and jolted by Jungkook’s rough thrusts.
“Namjoon-hyung… fuck, hyung… You feel so good!” Jungkook hissed hoarsely, his eyes tightly shut as he felt Namjoon’s hole clench and massage him so tightly with every thrust.
His large hands moved to Namjoon’s waist, gripping the skin there until it turned red, holding Namjoon in place so he wouldn’t shift as Jungkook pounded him from below with full force.
“J-Jungkook… a bit slower… ah!” Namjoon moaned, breathing heavily, his eyes rolling languidly upwards as a second wave of pleasure began to creep up through his groin.
“You were the one who asked for it harder, weren’t you, hyung?” teased Jungkook in his deep, resonant Alpha voice. “Take it all, hyung… don’t hold anything back.”
Jungkook quickened his pace even further until it became a relentless pounding. Each thrust sent a powerful tremor through Namjoon’s smooth, muscular chest and stomach, causing them to rise and fall dramatically. Sweat dripped heavily from Jungkook’s temples, falling to soak Namjoon’s chest, which was covered in purplish-red marks—signs of the Pure Alpha’s ever-increasing claims.
Namjoon grasped Jungkook’s firm upper arm, trying to find a hold amidst the storm of sensations overwhelming him.
“J-Jungkook… there… nhh! Keep going there… ah!”
“Here?” Jungkook asked hoarsely, then struck that spot with two consecutive, deeply penetrating thrusts.
“AAAH! YES! JUNGKOOK, YES!” Namjoon screamed uncontrollably, his voice filling the room.
The sensation of being satisfied by a Pure Alpha was on a level that nothing else could possibly match. Namjoon’s body—which had always been considered ‘defective’ and cold by other Alphas—now blossomed perfectly under Jungkook’s control.
His hole clenched tightly, automatically massaging and sucking Jungkook’s cock, demanding that his junior warm semen flood him once more.
Jungkook let out a low groan as he felt the unusual tightness of Namjoon’s hole. His arousal had now reached a second climax, far more intense than before. The veins in Jungkook’s neck and arms bulged sharply, tensing to their limit as he felt the knotting sensation of his cock begin to swell naturally—a biological process to lock his partner in place whilst claiming him.
“Hyung… I want to knot…” Jungkook hissed hoarsely, gazing at Namjoon with a look that was both a plea and an absolute command. “I want to fill you up with my knot and cum. "
Namjoon was slightly startled upon hearing the word ‘knot’. Locking two Alphas together in a biological union was an extremely rare occurrence and could potentially be painful if not accepted with resignation. However, seeing the intense, loving gaze in Jungkook’s eyes, Namjoon could only nod slowly amidst his ragged breathing.
“yess…—knot me, Jungkook… come inside me— fill me up!” whispered Namjoon, offering his unprotected neck to be bitten.
Hearing that permission, Jungkook growled low like a predator who had finally achieved total victory.
With three final, hard and deep thrusts, Jungkook’s swollen shaft was pulled to the very edge of Namjoon’s hole before being driven back in.
It burst fully inside, locking them both in a perfect, inseparable union.
“NHHHHH!” Namjoon let out a stifled scream, his eyes wide as an unimaginable sense of fullness locked around his lower body. His lower abdomen tensed rigidly, and in that very instant, Namjoon reached his climax for the second time. This climax was so intense that it sent Namjoon’s tall frame into violent spasms, his warm fluid gushing out and drenching both their chests.
At the same time, Jungkook buried his face in Namjoon’s neck, gently sinking his fangs into Namjoon’s pheromone gland to leave a temporary mating mark, just as his Pure Alpha semen erupted violently inside Namjoon’s body.
A massive amount of warm fluid filled the entirety of Namjoon’s passage, sealing their union in the stillness of the night.
Jungkook held himself above Namjoon, his breath coming in rapid gasps against the hollow of his senior’s neck. His large hands gently stroked Namjoon’s sweat-dampened hair, whilst their tightly locked union allowed the pheromones of the two Alphas to blend into a new, harmonious scent: warm cedar wood mingling with the sweetness of cinnamon and vanilla.
Namjoon lay limp beneath Jungkook’s embrace, his chest rising and falling steadily with his eyes closed in contentment. An overwhelming sense of exhaustion spread through every joint, yet deep within his chest, a warmth and fulfilment he’d never felt in his entire life now resided perfectly.
“I love you…” Jungkook whispered softly, kissing Namjoon’s limp lips with the utmost tenderness. “It’ll always be you, Namjoon-hyung.”
Namjoon gave a small smile amidst his ragged breathing, returning the kiss with what little strength he had left. “I know… You little rascal.”
