♡

From the moment he was born, Jeongguk had always seemed different. There was a quiet coldness about him that clung to him like a second skin. He didn’t like talking, didn’t like being in groups, and hated joining the other wolves during hunts. No matter how hard his parents or the elders of the pack tried to bring warmth out of him, it never really faded. Many children tried to befriend him, yet Jeongguk always remained apart, his dark eyes cold and distant, his expression rarely softening beyond a faint crease of irritation whenever anyone came too close or tried to talk to him.

Jeongguk himself never cared whether he was alone. Solitude had always felt natural to him. If this was the fate the world had chosen for him, he would accept it without complaint. But the Moon Goddess, the old stories said, had never intended for anyone to remain alone forever. Sooner or later, she always placed another soul in your path.

By the time he turned twelve, that grumpiness in him had only deepened. He answered questions with the fewest words possible, avoided the games of the other young wolves, and preferred quiet places deep in the forest where no one could bother him, where the pack’s territory stretched into the darker forest that few others ever bothered to explore.

One day, after a tiring training session in which the older alphas had pushed him too hard about his future responsibilities as the pack leader’s only son, he shifted into his wolf form without a word and slipped into the forest.

“Annoying,” he muttered to himself.

His paws moved quietly over the moss and fallen leaves. He had only planned to wander through the familiar paths, letting the silence calm the frustration. But something kept pulling at his instincts, as if it wanted him to take a different path, leading him farther away from the usual trails.

So he went deeper.

The trees grew thicker around him, and the forest became quieter with every step. Then, in a small clearing beside a narrow stream, he caught the scent of something unfamiliar.

Human.

He slowed, ears pricking forward, and peered through the low branches until he saw a child. The little boy, who looked no older than four, sat huddled against the base of a tree with his knees pulled to his chest, arms wrapped tightly around himself as though trying to stay warm. His clothes were torn and filthy, streaked with dirt and what looked like dried blood along one sleeve. His thin shoulders trembled continuously.

Jeongguk frowned. Why was a child here? Deep in the forest where wild animals hunted. What the hell were his parents doing?

He was about to turn away because it was none of his business and leave the matter for the border patrols when the shivering boy let out a small whimper.

He hesitated.

He remained half-hidden among the bushes, watching him. A strange uneasiness settled in his chest. The thought of such a small human being lost and injured so far from any village didn’t sit right with him. So he decided he would wait a little longer, just to make sure the boy’s parents were nearby or that someone was coming for him.

But then the child suddenly lifted his head and looked straight at him.

Their eyes met across the short distance. For a moment the boy simply stared, and then a tiny, unexpected smile curved his lips.

“Puppy,” he said in a quiet voice.

Jeongguk frowned harder.

He was not a puppy. They might have shared the same ancestors, but that didn’t mean he wanted to be called a dog. He was the future alpha of the pack, already larger and stronger than most wolves his age, and the casual word hurt his pride.

But strangely, it didn’t make him angry. He didn’t glare at the child either. The boy probably had never seen a wolf before. What unsettled him more than the name was the smile itself. Here was a little boy alone in the deep forest, injured, dirty, clearly exhausted, and somehow he still found the strength to smile at a wolf that could have been wild.

As though the creature in front of him was soft and safe.

Jeongguk didn’t like it. He didn’t like the way that fragile expression tugged at something inside him that he preferred to keep buried.

And he liked even less the thought of leaving the child alone now that evening was beginning to change into night and the forest would soon fill with wild animals.

The boy rose unsteadily, his thin legs wobbling beneath him, and began walking toward the large black wolf with complete determination. Because it was a puppy. The old woman near his house had once pointed at a dog and called it a puppy.

Jeongguk remained perfectly still, every muscle tense, as the small human closed the distance and then simply sat down right beside him.

“I’m very cold,” the boy mumbled, leaning closer to the wolf’s warm body.

Jeongguk stood rigid, unsure what to do with the unexpected child and the soft, tired voice that kept talking.

The boy spoke in a continuous, half-coherent stream, his words tumbling out between shivers.

“I’m hungry.”

“I saw butterflies earlier… pretty blue ones.”

“They looked like the ones in my book.”

“Mommy and daddy told me to wait right there. They said they’d come back soon.”

“I have school tomorrow.”

Jeongguk listened without moving.

Eventually the words slowed, and then they stopped entirely. The child’s breathing evened out, and his small body went limp against Jeongguk’s side as he fell asleep.

Jeongguk waited much longer than he needed to, ears straining for any sound of approaching footsteps or human voices. No one came, and the dark forest remained silent. At last he reached a quiet conclusion that no one was coming.

He looked down at the sleeping boy and sighed softly. “You’re coming with me.”

When Jeongguk returned to the pack territory, everyone was surprised to see a human child asleep in his arms.

“What happened?”

“Where did you find him?”

“Why is there a human boy here?”

Questions came from every direction, but Jeongguk answered none of them.

“Get the doctor,” he said simply.

The pack doctor cleaned the child, treated the fresh cuts and the older scars scattered across his thin body, and wrapped his injured arm carefully. Jeongguk remained nearby the entire time, until the boy finally stirred and opened his eyes.

The child looked around in confusion.

“Mommy?” he whispered.

His eyes landed on Jeongguk.

Jeongguk stepped closer.

“What’s your name?”

“How old are you?”

“Where are your parents?”

The boy answered in a small voice.

“My name is Kim Taehyung.”

“I’m five.”

“I go to kindergarten.”

“Mommy told me to wait… they said they would come back.”

From that night on, Jeongguk changed, though only a little.

He became warm only toward Taehyung.

He made sure Taehyung ate properly, that his wounds continued to heal, that he always had a warm place to sleep, and that he went to school every day.

Taehyung, for his part, followed Jeongguk everywhere, as though he had already decided that this one person was home.

Jeongguk began calling him “pup” in a reluctant voice that gradually lost its usual edge of irritation.

Taehyung answered with endless excitement.

“Hyung, look what I did!”

“Hyung, guess what I saw today!”

“Hyung, come here!”

“Hyung!”

“Hyung!”

And somehow, every time Taehyung called him “hyung,” the loneliness Jeongguk had carried for so many years didn’t feel as heavy anymore.

♡

The seasons changed, and Taehyung grew from the fragile five-year-old who had once been carried home in Jeongguk’s arms into a bright-eyed boy whose laughter could pull a rare smile from the future alpha.

Jeongguk himself grew taller and broader, his features sharpening, yet he never stopped looking after the human child who had somehow become the quiet center of his world. He continued to take his responsibilities as the pack leader’s son with the same cold seriousness he had always possessed, answering everyone with few words and training constantly. But whenever Taehyung was near, his cold exterior softened, melting into something careful and protective, because this was his pup, even if his pup was endlessly mischievous.

Taehyung would hide Jeongguk’s favorite training knife, only to return it later with a guilty little smile when the older boy pretended to search for it with exaggerated seriousness, sighing loudly and muttering, “Where could it have gone this time, hmm?”

Or he would insist on studying with Jeongguk, only to become distracted halfway through and start asking endless questions about wolves, the forest, and everything around him. Sometimes the lessons would be abandoned entirely, and the two of them would end up swimming together in the river instead.

Taehyung would splash water at Jeongguk without warning, laugh when the older boy frowned at him, and eventually come out of the water soaked from head to toe. Jeongguk would sigh again, and kneel to dry his hair with a cloth, the corners of his mouth twitching despite himself as he gently rubbed the water from Taehyung’s hair.

Taehyung would lean into those hands as though they were the safest place in the entire world, eyes half-lidded and content, murmuring, “Hyung’s hands are warm.”

Everything changed the year Jeongguk presented.

He presented as an alpha, just as everyone had expected, but Jeongguk wasn’t happy at all.

Taehyung, only nine years old, still small enough that Jeongguk could lift him with one arm, was his fated mate. The realization struck him like a physical blow, stealing the air from his lungs. How could fate be so cruel? How could he ever tell him?

Guilt followed that certainty almost immediately.

He was a wolf, an alpha whose instincts already reached far beyond brotherly care, pulling him toward the need to mate the one fate had chosen for him, and in those moments he found himself no longer caring that Taehyung was human… but a human could not be his mate.

When an alpha found their mate they marked them by biting deep into the curve of their neck, breaking the skin just enough for the mark to become permanent, scenting them relentlessly until their pheromones soaked into every pore and clung to every inch of skin so that no other wolf would ever dare come close. They spent their heat and rut cycles locked together, the alpha’s cock driving deep until the knot forced its way inside and held them joined for long minutes while seed flooded the mate’s body again and again.

How could a human body ever take an alpha’s thick cock, let alone stretch around the fat knot that locked them together so tightly neither could pull away? How could soft human flesh bear the intensity of an alpha’s rut, the endless, mindless, animalistic thrusting, the way an alpha’s instincts demanded to breed and fill until the mate was dripping and marked from the inside out or survive the very real possibility of pregnancy? In the pack, wolves sometimes shifted under the full moon and coupled in their animal forms, and for the first time in his life Jeongguk felt a deep disgust at the thought of touching the boy who still called him hyung with purest affection

Taehyung looked at him with the love of someone who had never known any other family, he was like a brother to Taehyung, the one who carried him when he was tired and scolded him gently when he played in dirt. The idea that the Moon Goddess had tied them together that might one day demand far more than brotherly care made Jeongguk’s stomach twist with heavy shame.

In the days and weeks and months and years that followed, he continued to care for Taehyung exactly as he always had, spoiling him with sweet treats from the human villages, making certain he attended school among his own kind so he would never feel entirely cut off from the human world.

He changed Taehyung’s school to a human school beyond the pack borders. He kept his distance wherever he could, training longer, taking more night patrols, answering Taehyung’s chatter with shorter replies, yet something inside him had already begun to shift no matter how carefully he tried to hold the line.

He found himself watching the way Taehyung moved, the way the boy’s body had begun to change over the years, and the way his pup looked as the last traces of early childhood slowly faded away. Taehyung grew taller, his features losing his chubby cheeks and changing into something quietly beautiful, large, pretty eyes, full red lips, and a faint blush that always rose on his cheeks whenever Jeongguk’s gaze lingered a second too long.

He watched him with carefully buried longing, still spoiling him, still calling him pup, still answering every need even while his instincts screamed that this was his mate. How could he keep him close when every alpha instinct now saw him as a mate? And how could he ever push him away when Taehyung had no one else in the world?

By the time Taehyung reached puberty, the air between them had changed in a way neither of them had expected. Taehyung no longer liked it when his hyung stayed busy with endless pack duties, the distance made something restless and aching stir inside his chest. He had always loved Jeongguk, of course, loved him the way a child loves the only family he has ever known, but that feeling had slowly begun to change, growing into something deeper and more confusing. He wanted to be near him all the time, wanted to stay close to him, and now those feelings carried a desire he couldn’t understand.

He had overheard the wolves (?) speaking in low voices about mates, about the way an alpha’s pheromones would wrap around their mate, they talked about how pairs sometimes shifted into their wolf forms and ran together through the dark forest in a joyful chase that ended with bodies tangled on the forest floor, the alpha mounting their mate. He had also caught fragments about an alpha’s rut and the knot, enough to leave him restless with far too many questions he could not ignore, what exactly a knot was?

When he finally gathered the courage to ask Jeongguk, his expression had darkened, he had scolded him, demanding to know who had filled his innocent mind with inappropriate talk and telling him it was nothing a child needed to concern himself with. Yet Taehyung’s curiosity refused to die. He waited until Jeongguk was away on patrol and asked one of the more talkative betas instead, listening with wide eyes as he explained that every six months an alpha had rut, an overwhelming animal instinct that drove them to seek their mate, to have sex again and again, to breed them until they were full and claimed.

The beta had added, winking at Taehyung, that an alpha had a thick knot at the base of his cock, and that once it was buried deep it would swell and lock the pair together so neither could pull away. “You understand where it locks, right?” he asked.

Taehyung shook his head, cheeks already warming, and the beta clicked his tongue with a small, knowing smirk. “Of course you don’t… you’re human,” he murmured, then leaned in a little closer to explain. “When an alpha is having sex with their mate, even if that mate is male, his penis goes into the back hole. He pushes all the way in until the knot slips past and then it swells up big and tight, locking them together while the alpha keeps releasing inside… sometimes for a long time. And yes, even a male omega can be made pregnant that way.”

The blunt words made Taehyung’s face flush hot and his ears burn, a strange, fluttering heat settled low in his stomach as images he barely understood flickered through his mind, and beneath the embarrassment the only clear thought that remained was the quiet, desperate hope that his hyung might one day be his mate too.

To Taehyung, his hyung was no longer simply hyung. Jeongguk had become the center of every daydream, the secret crush he carried quietly against his heart, and after everything the beta had explained the images in his mind had grown far more vivid. He wanted to kiss him, softly at first, just to learn the shape and warmth of his serious lips, and then longer, deeper, until the coldness Jeongguk sometimes wore finally melted away. He wanted to curl against his hyung’s broader chest and stay there for hours, breathing in the familiar scent that now made his pulse stutter and his skin tingle, wanted to feel his strong hands settle on his waist instead of only ruffling his hair in the old brotherly way.

Sometimes at night he would lie awake in the room and imagine Jeongguk turning toward him in the dark, voice deep and rough as he called him pup, only now the word carried a different weight. He wondered whether his hyung would ever look at him the way the alphas looked at their mates, whether his hands would pull him close and claim him properly, marking him, scenting him, pushing inside him… and mating him… knotting him. The thought alone made heat pool low in his stomach, equal parts nervous and aching, and the only thing Taehyung knew for certain was that he wanted it to be true, he wanted his hyung to be his mate, and he wanted every part of what that meant.

The longing sat heavy and sweet in his chest, tangled tightly with the fear that Jeongguk would never see him as anything more than the little human he had once rescued from the forest. Yet every time their eyes met across, Taehyung felt the same pull deepen, and all he could do was want more.

♡

By the time Taehyung turned eighteen he was still Jeongguk’s pup, yet the truth of Taehyung being his mate continued to weigh on the alpha like a stone pressed against his ribs. Taehyung had grown into a young man whose beauty only sharpened the ache into his heart, and the pull became almost unbearable, the harder Jeongguk tried to keep his distance the more fiercely his instincts clawed at him to close it.

He was twenty-five now, and from the moment of his first rut until the present he had endured every cycle alone. The suppressant medicines did nothing, his own hand brought only brief relief that left him emptier afterward. Night after night he had locked himself away, cock thick and leaking in his fist, knot swelling uselessly against nothing while his mind filled with forbidden images of the one person he could never allow himself to touch. He watched Taehyung move, laughing, stretching, looking at him, and every moment only made the darker hunger inside him grow stronger. What if he could finally touch him, pin him against the nearest tree and kiss his soft red lips until they parted on a moan? And then… mate him? The thought alone made Jeongguk feel filthy, disgusting, because the boy he had raised still looked at him with pure trust, and he had no right to stain that trust with the dark desire of an alpha in rut.

How could he ever tell him the truth? How could he look into his eyes and explain that the Moon Goddess herself had tied their lives together when Taehyung did not even fully understand what a fated mate meant?

One day Taehyung dragged him down to the stream, the same place where they had spent countless hours over the years. Both of them sat on the stones, the water streaming past their feet, yet Taehyung had been unusually silent all day. His usual bright chatter had changed into long silence that Jeongguk noticed but deliberately chose not to question, afraid of what might spill out if he pressed. At last Taehyung turned toward him, knees drawn up and arms wrapped loosely around them, dark hair falling into his eyes.

“Hyung,” he said softly, “what’s wrong with me?”

Jeongguk’s entire body went still. “Nothing is wrong with you, pup,” he answered at once. “Why would you ask that?”

Taehyung shifted a little closer, close enough that his scent brushed against Jeongguk’s senses. “You don’t spend time with me anymore,” he mumbled, staring at the water. “Not like before.”

Jeongguk opened his mouth, the name “Taehyung” already forming, but the younger man cut across him before the word could fully leave his lips.

“They said it’s because you have a mate.” That made Jeongguk freeze.

Taehyung’s voice stayed quiet, yet the hurt beneath it was unmistakable. He had been so happy for a single, foolish moment when the rumor first reached him, thinking that perhaps the mate the others whispered about was him, after all, he was the only one who stayed at Jeongguk’s side, and the hope had bloomed bright and fragile before reality crushed it. Not everyone was granted a mate, especially not a human. The more he thought about it, the more he realized that his hyung had been keeping his distance for months.

At first Taehyung had told himself his hyung was simply busy with the endless duties of a future pack leader. Later he wondered whether the alpha had somehow sensed the crush he tried so hard to hide and had chosen distance. Now the truth seemed far more painful. His hyung already had a mate somewhere out there, and that was the real reason the space between them kept growing.

“I’m not a werewolf like you,” Taehyung continued, the words tumbling faster now as the carefully held feelings finally spilled over. “I’ve been thinking about it a lot lately. Everyone else in the pack has a mate. They shift, they present, they find their mates. But me… I’m just a human who has no one except you. And now I find out you already have a mate. Is that why you’ve become so distant with me?”

The question struck Jeongguk in the chest. It was not like that at all. Yes, he had a mate, but he could not simply turn and tell his pup that the person sitting beside him was the very one fate had chosen. He turned fully toward Taehyung, and the vulnerability in those familiar eyes made the walls he had spent years building begin to crack. Without thinking he reached out and gently brushed a strand of hair away from Taehyung’s forehead, fingertips lingering a second longer than they should have.

“No,” he said firmly. “No, pup. It’s not like that. I’m sorry if you’ve felt me becoming distant. It’s just…”

Taehyung’s frown deepened, hurt and confusion written plainly across his face. “So you do have a mate?”

This time Jeongguk did not deny it. The silence that followed was answer enough, and Taehyung’s mouth curved into a small, bitter smile that looked entirely wrong on him. “I wish hyung was my mate,” he whispered.

Jeongguk stared, certain he had misheard. “What did you just say?”

Taehyung’s cheeks flushed, but he did not look away. “Sometimes when you’re near I feel this strange pull in my chest, like something inside me is reaching for you. I just want to be with you… no matter how much I touch you it never feels like enough. I want you so much… like a mate would. But now… if I left, I can’t even imagine it. I can’t live without you. Don’t you know that?”

Jeongguk’s heart stopped. “Why are you talking about leaving?”

“Because you have a mate,” Taehyung mumbled, eyes dropping to the water again.

“You’re not going anywhere,” Jeongguk said at once, the alpha command rising rough in his throat.

“I have to,” Taehyung insisted, voice cracking. “I can’t stay here and watch you with someone else.”

The last of Jeongguk’s restraint snapped. He had no choice left, not when it was Taehyung looking at him with a broken expression, not when the bond between them was screaming to be acknowledged. He reached out, cupped the younger man’s face in both hands, and forced their eyes to meet.

“Pup,” he said, the word low and rough with everything he had kept buried, “you’re my mate.”

The confession hung in the air between them. Jeongguk loved him. He had loved Taehyung in every way that mattered for far longer than he had ever allowed himself to admit, loved the child he had once carried out of the dark forest, loved the boy who had filled his quiet, cold world with endless chatter and mischief, and now loved the young man whose very presence made his blood run hot and his carefully held control begin to fray. Every instinct he possessed, the deep alpha hunger he had spent years starving into silence, recognized Taehyung as his, the soft scent that clung to his skin, the curve of his mouth, the way his body would fit so perfectly beneath Jeongguk’s own if he ever allowed himself to reach out and take. The truth was out and there would be no taking it back.

♡

Jeongguk no longer tried to keep the distance he had made, instead he stayed close, and Taehyung, whose long-hidden crush was no longer a secret, took every opportunity to close the remaining space. He had pressed a shy kiss to Jeongguk’s cheek while the alpha was still half-asleep, on nights he curled against him without hesitation. Tonight they were tangled together in Jeongguk’s bed, Taehyung’s head resting against the alpha’s bare chest while Jeongguk’s arm held him securely around the waist.

“So the pull I feel… that’s the bond?” Taehyung whispered, fingers tracing patterns over skin. “I’m your fated mate?”

“Yes.” Jeongguk’s answer came, his hold tightening just enough to pull Taehyung more firmly against him. “You are my fated mate. And I’ve spent a long time feeling guilty about it, because I never wanted you to feel trapped by something you didn’t choose. You grew up trusting me as family. I never wanted to take advantage of that trust.”

Taehyung lifted his head and shifted until he was across Jeongguk’s naked chest, bare skin against bare skin, and the steady beat of the alpha’s heart strong beneath his cheek. “Hyung, you make me so happy,” he said, voice soft with wonder. “Do you know how happy I am when I think about the fact that you’re my mate? I get these tingling feelings in my stomach, like butterflies dancing every time you’re near.”

Jeongguk chuckled. “Oh yeah?”

Taehyung’s face turned a deeper red at the teasing tone, especially because he had always loved the way Jeongguk’s voice roughened when they were alone, like being intimate in the dark. Before he could hide against the alpha’s shoulder, Jeongguk spoke again, lips brushing the side of Taehyung’s neck.

“I love you,” he said quietly. “I’ve loved you in every way that mattered for longer than I ever admitted to myself. And I will never push you away again. If you want to stay, if you want this bond, then I’ll spend the rest of my life making sure you never regret it.”

Taehyung smiled, and without giving himself time to overthink he leaned up and pressed his mouth directly to Jeongguk’s. The kiss was soft at first, almost hesitant, but the moment their lips met Jeongguk froze in quiet shock, his pup had grown up far more boldly than he had realized. When Taehyung pulled back just enough to speak.

“I want to stay. I want you. I don’t care that I’m human and you’re a wolf. I only care that you’re mine, the same way I’ve always been yours. And I love you too, hyung. Now kiss me properly.”

Jeongguk looked down at him, and whatever restraint he had left finally slipped. Taehyung had stirred every buried desire into awareness, the alpha’s eyes darkened as he cupped the back of Taehyung’s head and kissed him. He nipped gently at the full lower lip until it parted, then slid his tongue inside the small, hot mouth, tasting him thoroughly. The kiss turned deep and wet, tongues sliding together in slow thrusts, Jeongguk exploring every soft corner while Taehyung made quiet, needy sounds against him. When he finally drew back, Taehyung’s face was flushed a pretty pink, lips swollen and shiny, eyes glassy with want.

“Hyung,” he murmured, voice a little breathless, “when two people are mates… what happens next? I mean, beyond the bond. I’ve heard them talking about marking and mating and things I don’t really understand. Will you show me? Will you let me be close to you the way mates are supposed to be?”

Jeongguk’s arm tightened around him, his breathing no longer quite steady as desire stirred hot in his belly. Heat pooled thickly between his legs, his cock gave a heavy twitch against the confines of his pants, already beginning to thicken at the mere thought of mating the young man in his arms. He forced the reaction under control, refusing to rush what had taken them so long to reach.

“Only when you’re ready, pup,” he said, voice roughened by the effort of restraint. “And only if you understand that once we take that step there’s no going back. The bond will become complete. I don’t want to rush you.”

Taehyung looked up at him, curiosity in his eyes, and it was clear he could barely stand to wait at all.

And from that night onward Taehyung wanted nothing more than to be claimed and mated by Jeongguk, and he made that desire known with a persistence that left the alpha no room to keep hiding behind restraint.

“Hyungggg,” Taehyung whispered against the side of Jeongguk’s neck, voice soft and almost pleading as his fingers curled into the fabric of the older man’s shirt, “please… I’m ready. I’m not a child anymore.”

Jeongguk let out a long, heavy sigh, the sound rough with both hunger and the last remnants of caution. He knew that if it was not tonight then it would have to be some other night soon, because the bond between them was already pulling them together, and the truth was that he wanted Taehyung so much. Still the fear of hurting him lingered.

“Only if you are certain, pup,” Jeongguk said at last, his voice measured. “Once we begin there is no taking any of it back. My wolf will claim you. The bond will settle completely. And… you know we are physically different from humans.” He stopped himself before he could say the rest aloud, that his cock was nothing like an average human male’s, thicker and heavier, with a fat knot that would hurt him. But had his pup ever even seen a penis other than his own? Jeongguk doubted it.

Taehyung only nodded, unmistakably eagerness, as though he understood everything. “I am certain,” he answered without hesitation. “I trust you more than anyone. Show me. I want it.”

They undressed one another with unhurried hands, every movement gentle, the quiet bedroom broken only by the soft rustle of fabric and the increasingly uneven sound of their breathing. Jeongguk’s palms touched Taehyung’s body as though memorizing them, and felt impossibly soft beneath his calloused fingers. The scent that rose from Taehyung once the last of his clothes had been stripped away hit Jeongguk, sweet and warm and already tinged with arousal, and his cock hardened so instantly.

Taehyung’s chest rose and fell in shallow breaths, the small brown nipples already peaked, and the sight of them made Jeongguk’s mouth water with the sudden urge to close his lips around each one and suck until Taehyung was squirming. The narrow waist that seemed as though it could be covered by a single hand, the plush curve of an ass that squished perfectly under his fingers, and the pretty, flushed cock that stood half-hard against Taehyung’s lower belly, Jeongguk found himself staring shamelessly.

Every place Jeongguk’s hands touched left goosebumps, and Taehyung felt the heat rising so fast beneath his skin that he suddenly wanted to whimper. His hyung was broader, stronger, every hard muscle shifting whenever his soft hands touched.

Jeongguk kissed Taehyung’s plump lips at the same moment his fingers groped that perfect ass and squeezed, drawing a moan straight into his mouth. He pushed Taehyung down onto the bed and then spent long minutes simply kissing every inch of him, trailing wet, open-mouthed kisses from those swollen lips down the column of his throat, across the sensitive buds of his nipples, over the trembling plane of his stomach, and finally to the flushed length of his cock. Jeongguk’s own cock hung heavy and hard between his thighs, the thick cock head already leaking. Then he licked up the clear precum that dripped from Taehyung’s tip, savoring the taste while his alpha pheromones filled the air so thickly that any wolf would have known exactly how aroused he was.

He spread Taehyung’s legs wider, settling between them, and the younger man trembled with a sudden wave of shyness that made his thighs try to close again. Jeongguk only pushed them back open with firm but gentle hands. “Don’t be shy with me, pup,” he murmured, voice dark with hunger. “Not when you’re already leaking and open for me.”

Three thick fingers pressed against Taehyung’s lips next, and Jeongguk ordered him to suck. Taehyung obeyed at once, taking the digits deep and working his tongue around them until saliva dripped down Jeongguk’s wrist. The fact that Taehyung seemed to have no gag reflex at all made the alpha’s eyes darken with pure lust. When the fingers were dripping wet he pulled them free and began working them one by one into the tight, little ass hole, stretching him open with slow, careful thrusts.

Taehyung found the sensation strange and overwhelming at first, his toes curling against the sheets while Jeongguk’s mouth continued to kiss and bite along the inside of his thighs. Two fingers became three, and by the time the fourth joined them the stretch burned enough that tears pricked at the corners of Taehyung’s eyes, yet he never once said it hurt. Instead he looked up at Jeongguk through lashes and whispered, “Hyung… put your cock in me.”

Jeongguk paused, a low growl came as he asked, half-amused and half-possessive, where exactly his innocent pup had learned to say such filthy things.

Taehyung only smiled shyly in answer, cheeks flushed a deep pink.

Jeongguk positioned himself between those open thighs, the broad, wet head of his cock pressing gently against the prepared entrance. He pushed forward inch by inch, watching every flicker of expression that crossed Taehyung’s face, pausing whenever the younger man’s breath hitched. The sensation of being covered in the tight, welcoming hole drew a groan from the alpha’s throat.

“You feel… so much,” Taehyung whispered once Jeongguk’s cock was fully inside. “But it is good. Keep going. Please…”

Jeongguk began to move, thrusting deep and slow at first, and the thick length of him created a visible bulge against Taehyung’s stomach with every roll of his hips. Taehyung’s ass hole was stretched lewdly around the girth of the alpha’s cock, the rim flushed and glistening, and Jeongguk had to lock every muscle in his body to keep from snapping and fucking into that perfect heat like a mindless beast. He groaned again, because it was simply too delicious, hot and tight and clenching around him as though Taehyung’s body had been made to take him and nothing else.

The thrusts that had begun slow and careful soon turned relentless, the slap of skin against skin filling the bedroom in a rapid, lewd rhythm while Taehyung’s cute pink cock bounced and leaked steadily against his own stomach, smearing clear fluid across belly with every deep thrust of Jeongguk’s hips.

Jeongguk kissed him everywhere he could reach, crushing their mouths together until Taehyung’s lips were swollen and shiny, then trailing hot open-mouthed kisses down to the peaked nipples so he could suck and bite at them until the younger man was arching and crying out, only to return again and again to those plush lips.

The room echoed with nothing but the lewd sound of Jeongguk’s balls smacking against Taehyung’s ass, the sweet moans spilling from Taehyung’s throat, and the repeated, breathless “hyung… hyung…” that had always been Jeongguk’s favorite sound in the entire world.

“Do you like it, pup?” Jeongguk muttered against his lips, never slowing the thrust of his hips.

Taehyung could only nod frantically, tears dripping from the corners of his eyes as pleasure twisted through him. “Yes… yes… hyung, nghh, so much…” The words broke off into a cry as his cock pulsed hard and he came untouched, cum painting his stomach and chest while his hole clenched around the thick cock pounding into him.

Jeongguk only chuckled, the sound dark and fond, because the night was far from over and his own cock had not spilled even once yet.

He pulled out just enough to rearrange them, manhandling Taehyung into his lap so the younger man was straddling him, the messy, stretched hole hovering right above the glistening length of Jeongguk’s cock. “Pup, ride my cock,” he ordered. “Up and down… yeah, just like that.”

Taehyung tried his best, rising on shaky thighs and sinking back down, but the stretch was still overwhelming and his movements remained clumsy and sweet. Jeongguk took over almost immediately, gripping his narrow hips and thrusting upward with brutal strength. Each time he withdrew until only the fat cock head remained caught inside the fluttering rim, then slammed back up so hard and deep that it looked as though he was trying to force his heavy, dark balls inside as well. The sight was obscenely lewd, Taehyung’s pink, flushed ass stretched wide around the thick shaft, the soft cheeks jiggling and reddening as they slapped down against Jeongguk’s balls that were already heavy and covered in dark pubic hair.

Thrust after thrust after thrust followed without mercy, the filthy sound of their joining growing louder as Jeongguk fucked up into that perfect hole over and over. Taehyung came more than once in that position alone, his pretty cock spurting weakly across Jeongguk’s abs, and they changed positions again and again, Taehyung on his hands and knees, then on his side with one leg hooked high over Jeongguk’s shoulder, then flat on his back with his knees pressed almost to his ears, until the alpha was finally braced above him once more, sweat dripping from his forehead and rolling down the hard planes of his chest while Taehyung lay thoroughly fucked-out beneath him, eyes glassy and lips parted on continuous soft moans.

When the base of Jeongguk’s cock began to swell with the first true pressure of the forming knot, he slowed at once and started to ease back, determined not to force more than a human body could safely take. Taehyung’s hands shot up to grab his shoulders, shaking his head frantically.

“Ngh… no, no… don’t pull out…”

“I’ll still fuck you, pup,” Jeongguk gritted out, every muscle trembling with the effort of holding back. “It’s the knot… I have to pull out before it locks…”

But Taehyung only shook his head harder, legs locking more firmly around the alpha’s waist and heels digging into the small of his back to prevent any retreat. “No, no, hyung… I already took your cock… ahh, please, please… why can’t I take your knot too? Please knot me…”

Jeongguk’s breathing turned ragged, the strain of restraint visible on his face and the way his arms shook on either side of Taehyung’s head. “It will stretch you even further. It will lock us together for a long time, and it can hurt so much… pup, you’re human. There’s no taking it back once that knot is inside you.”

Taehyung’s gaze stayed steady and stubborn despite how exhausted and thoroughly fucked he already looked, tears still clinging to his lashes. “I can… I want it. Hyung, please… knot me, please…” he begged, voice breaking on the last word.

Those desperate pleas undid the last of Jeongguk’s resistance. He pressed forward again, watching Taehyung’s face with intensity as the knot met the tight ring of muscle and began to push inside. A sharp sound tore from Taehyung’s throat, half pure pain, half overwhelming fullness, and Jeongguk immediately stilled, murmuring continuous sweet praise against his temple while one large hand stroked soothing circles over the younger man’s hip.

“Breathe for me, pup. Easy now. I have you. Tell me if it’s too much.”

Taehyung’s fingers dug hard into his shoulders, nails leaving marks, yet after a moment he shook his head, eyes bright with tears that were no longer only from the brutal stretch. “It hurts… but I still want it. Keep going… ngh… please don’t stop.”

With a final, careful thrust Jeongguk’s knot finally slipped past the resistance and seated fully inside, locking them together in the most intimate way possible. The moment it locked he started cumming, thick, hot ropes of seed flooding deep into Taehyung’s body in pulse after heavy pulse until the younger man’s belly rounded slightly from the sheer volume. Taehyung moaned at the sudden intense pressure and heat, his entire body trembling around the locked knot, yet his arms only tightened around Jeongguk’s neck as the alpha held him through every spurt.

Even locked tight, Jeongguk began to move again in the limited way the knot allowed, tiny, grinding rolls of his hips pressing continuously against the sensitive place deep inside Taehyung while his hand returned to the younger man’s spent cock, stroking it with gentle care.

The dual stimulation of the locked knot grinding against the sensitive place deep inside him and Jeongguk’s hand stroking his spent cock proved far too much for Taehyung to withstand. He came with a cry, his hole clenching rhythmically around the knot as overwhelming pleasure finally overtook the pain of being so stretched and filled.

Jeongguk buried his face against the curve of Taehyung’s neck, a low growl came while the knot pulsed harder, still releasing thick ropes of cum that kept flooding the younger man’s already-stuffed hole. At the same moment his mouth found the perfect spot where neck met shoulder, and instinct mixed with years of buried love guided him to claim his mate forever.

He bit down firmly, fangs piercing the soft skin just deeply enough to leave a permanent mark, yet careful never to cause more pain than was necessary. Taehyung gasped at the sharp, sudden sting, then melted even further into the mattress as the mate bond became complete between them, a certainty filling both of their hearts and minds until there was no longer any doubt that they belonged to each other completely.

They remained locked together for nearly two full hours afterward, Jeongguk carefully rolling him onto the sides so that Taehyung would not have to bear his full weight. Throughout every minute the knot kept them joined he spent the time pressing soft kisses to every part of Taehyung’s face, forehead, eyelids, the tip of his nose, the lips, while murmuring praise and affection against his skin and his hands stroke continuously over sweat-damp flesh in the gentlest aftercare. He whispered how perfect Taehyung felt around him, how beautiful he looked when he came, how proud he was of his brave pup for taking his cock and the knot, all while the leftover cum continued to leak out around the base whenever either of them shifted even slightly.

When the swelling finally softened enough for Jeongguk to slip free, a thick gush of cum immediately followed, spilling out of Taehyung’s gaping, well-fucked ass hole and down the insides of his thighs in messy trails. The sight alone was enough to make the alpha’s cock twitch back toward full hardness. He fucked Taehyung again and again, slow and deep at first while the younger man was still soft and open from the knot, then harder once Taehyung began to moan and push back for more, until both of them were thoroughly exhausted and the sheets beneath them were ruined with sweat, and cum.

Only when the early morning began Jeongguk finally stopped. He cleaned his pup with a warm, damp cloth, taking his time to wipe every trace of cum from Taehyung’s soft stomach, the insides of his thighs, and the tender, puffy rim of his hole. He applied an ointment to the fresh mate mark on his neck and to the used place between his legs, and then gathered the younger man close against his bare chest beneath the blankets, wrapping both arms around him protectively.

Taehyung’s voice was soft and drowsy when he finally spoke again, the words mumbled against Jeongguk’s collarbone. “Hyung… it hurt a little, but it was still perfect. I love you so much.”

Jeongguk’s arms tightened around him. “I love you too, pup. More than I have ever known how to say. You are mine, and I am yours, for as long as the moon keeps turning. Rest now. I will be right here when you wake.”

Taehyung answered in a hum as he burrowed even closer, exactly the same way he had done since the night a cold, grumpy wolf first carried a shivering human child out of the deep forest and into his life.

Jeongguk pressed one last kiss to the top of Taehyung’s hair, breathed in his scent, and finally closed his eyes.

I really enjoyed writing this one ☺️ but tbh it looks easy to write but it really wasn’t. I had a lot planned but once I started writing, it was about to become more than 12k words so yeah, I had to re-plan a few things because I didn’t want it to go over 8k words.

A little fact: the reader who requested this chapter specifically didn’t want it to be too filthy or kinky.

And “Always Daddy’s” was actually requested by two people and this reader was one of them. They had requested a particular scene and they not really wanted kinky but other person wanted it to be kinky so it ended up becoming way more explicitly kinky and I honestly didn’t know it would be enjoyed by everyone lol

♡

Also, please read my posts!

The first one "Please Read". I sometimes update and edit it so it’s a good idea to check it from time to time for any issues!!

The second one "Schedule". If you requested something and don’t see it in the schedule, that means it’ll probably come next month. So please wait patiently and do check out the schedule post if you’d like to know what’s coming next!

And the third one "AO3". I’m not updating anything there right now but I’ll be back on AO3 soon. The free chapters I’m publishing here on Stck.me will move to AO3.
