Sunghoon had always been meticulous when it came to Sunoo’s heats. He kept track of the cycle on his phone, had reminders set two weeks in advance, and stocked their apartment with everything Sunoo might want. Even when Sunoo teased him for being overprotective, Sunghoon didn’t let up.

“Better ready than panicked,” he’d said last night, tucking Sunoo in. “One week to go.”

Sunoo had only laughed, rolling his eyes. “You worry too much. I’ll be fine.”

But by Thursday afternoon, he wasn’t fine.

The office was humming with the low monotony of keyboards, printers, and half-hearted chatter. Sunoo had been halfway through an email when it slammed into him — heat, sudden and overwhelming, like his body had been set ablaze from the inside. His skin prickled, sweat breaking out along the back of his neck. Every sound grew sharper, every scent unbearably vivid.

He dropped his pen. His hands shook.

No, no, it’s too early… I still had a week.

The panic only made it worse. His coworkers’ voices blurred together, meaningless noise against the rush of blood in his ears. He mumbled something about not feeling well, forcing a smile, but he couldn’t remember if they answered back. All he knew was that he had to get out.

By the time he stumbled through the glass doors and into the open air, his breathing was ragged, chest heaving like he’d run miles instead of two flights of stairs. The crisp air cooled his cheeks, but his body still burned.

His fingers were clumsy on his phone, but they didn’t need to be precise. He only ever called one person in moments like this.

The line picked up almost immediately.

“Sunoo?” Sunghoon’s voice was sharp, steady, the exact anchor Sunoo needed.

Sunoo pressed the phone tighter against his ear, eyes squeezing shut. “Hoon—” His voice cracked, humiliatingly thin. “It started. Too soon. I—I can’t—”

There was a pause, barely half a second, before Sunghoon’s tone shifted, low and commanding. “Where are you?”

“Outside,” Sunoo whispered, glancing helplessly at the blur of people passing him on the sidewalk. “Front of my building. I just—I need you.”

“I’m already on my way,” Sunghoon said. “Stay where you are. Don’t try to get home alone. Don’t move, Sunoo. I’ll find you.”

The call ended, but his words lingered, steadying Sunoo enough to keep him rooted in place. He wrapped his arms around himself, rocking slightly, ignoring the curious stares of strangers. Minutes dragged, each one louder and hotter, until a familiar car pulled up to the curb.

Sunghoon didn’t even bother parking properly, hazard lights flashing as he helped Sunoo in the seat. “Get in.”

Sunoo scrambled inside, relief flooding him at the sight of his alpha. Sunghoon’s scent filled the car, crisp and grounding, and Sunoo nearly sagged against the door.

Sunghoon reached over, brushing damp hair from Sunoo’s forehead. His expression was tight, controlled, but his touch was gentle. “Breathe, Sunoo. I’ve got you now.”

Sunoo’s throat worked as he nodded, words tangled in his chest.

The drive was quick but tense, Sunghoon’s hand gripping the wheel with one hand, the other occasionally brushing against Sunoo’s knee, grounding him each time Sunoo twitched or whimpered quietly.

By the time they reached the apartment, Sunghoon was already in motion—guiding him inside, shutting the blinds, checking the nest they’d set up last week.

“I knew we should’ve prepared sooner,” Sunghoon muttered under his breath, more to himself than Sunoo, before his tone softened again. He tilted Sunoo’s chin up, eyes steady on his. “You’re safe now. Just focus on me.”

Sunoo leaned into him, trembling but comforted. “I didn’t mean for it to happen early—”

“Shh.” Sunghoon pressed his forehead to Sunoo’s, his voice firm and soothing. “It doesn’t matter. I’ll take care of you, no matter when it comes.”

And with that, the panic eased.

Sunghoon didn’t let go of Sunoo until the door was locked and bolted behind them. He kicked off his shoes in a hurry, then helped Sunoo with his, steadying him when his knees buckled.

“Easy,” Sunghoon murmured, his voice calm in a way that didn’t match the worry flickering in his eyes. “You’re safe now. Just breathe.”

Sunoo leaned heavily against him, the heat still coursing through him like fire under his skin. His fingers curled into Sunghoon’s sleeve, clutching like he might float away otherwise.

Sunghoon’s hand came up to cup the back of his neck, thumb stroking over damp skin. “You’re burning up. Let’s get you settled.”

He guided Sunoo down the hallway, every step measured, until they reached the bedroom. The nest was already there—soft blankets, extra pillows, a space that smelled faintly of them both. Sunghoon had insisted on setting it up days in advance, and now, Sunoo was grateful for his fussing.

As soon as Sunoo sank onto the bed, his body sagged with relief. The familiar scents wrapped around him, grounding him, even as his pulse thundered.

“Stay here,” Sunghoon said softly, brushing Sunoo’s hair back from his flushed face. “I’ll get water. You need to stay hydrated.”

Sunoo caught his wrist weakly before he could pull away. “Don’t leave.”

The plea was thin, almost desperate, and Sunghoon’s expression softened immediately. “I’ll be two steps away. You’ll still hear me. Okay?”

Reluctantly, Sunoo let him go. True to his word, Sunghoon returned within seconds, kneeling at the edge of the nest with a cool bottle of water. He twisted the cap off and pressed it gently into Sunoo’s hands.

“Slow sips,” he said, watching closely as Sunoo obeyed.

The water helped, cooling his throat, but the heat inside him still simmered, unrelenting. He shifted restlessly, burying his face into one of the pillows. It smelled like Sunghoon—crisp, steady, comforting.

Sunghoon reached out, smoothing a hand down his back in long strokes. “I hate that this hit you early,” he muttered quietly. “I should’ve seen it coming.”

Sunoo shook his head, muffled against the pillow. “Not your fault. I didn’t even feel it until—” His voice cracked, the memory of panic slipping through.

“Shh.” Sunghoon’s hand stilled, then pressed firmly between his shoulders, grounding him. “Don’t think about that part anymore. You’re home now. With me.”

Something in his voice—steady, absolute—unwound the last of Sunoo’s panic. He shifted again, rolling onto his side so he could see Sunghoon properly. His eyes were glassy, cheeks still flushed, but his breathing had evened out some.

Sunghoon brushed his thumb along Sunoo’s cheekbone, his gaze unwavering. “You know I’ll always come for you, right? No matter where, no matter when.”

Sunoo’s lips trembled into the faintest smile. “I know.”

“Good.” Sunghoon leaned down just enough to press a firm kiss to his forehead, lingering there. “Now rest. Let your body do what it needs. I’ll stay right here.”

And he did. Sunghoon didn’t move from his place at Sunoo’s side, one hand resting over his, his presence steady and unyielding. Every time Sunoo shifted or whimpered, Sunghoon’s touch was there—calm, grounding, protective.

Sunoo drifted in and out of sleep, waking to the sensation of Sunghoon’s fingers running through his hair, or his soft voice, or the steady press of his body against his back. He woke once to find himself tucked against Sunghoon’s chest, the alpha’s breathing slow and even behind him. Sunghoon’s arm tightened around him as he stirred, a silent reassurance.

When Sunoo woke again, it was to darkness outside the window. The room was dim, illuminated only by the hall light spilling in through the cracked door. Sunghoon wasn’t beside him.

He sat up too quickly, head spinning at the sudden movement. He was alone in the nest, the sheets warm and rumpled around him. Panic fluttered in his chest.

“Sunghoon?” he called out, his voice still too soft, too fragile.

No answer.

Sunoo pushed himself up, ignoring the sharp protest of his muscles. He made it to the edge of the bed before a wave of dizziness forced him to pause. He gripped the mattress hard, breathing through the haze of heat and fatigue.

The apartment was silent, save for the low hum of the air conditioning. Sunoo strained to hear any sign of Sunghoon—footsteps, a murmur, anything—but there was nothing.

“Hoon,” he tried again, louder this time, but the name caught in his throat, ending in a cough.

He had to find him. Had to make sure he was still there, still his, still willing to stay through this. The fear was irrational, he knew, but it clung to him anyway.

With careful, shaky steps, Sunoo made his way to the door. The living room light was on, casting a warm glow down the hallway. Relief washed over him as he caught sight of the kitchen—Sunghoon’s broad back visible where he stood at the counter, his shoulders tense but familiar.

Sunghoon turned just as Sunoo reached him, a glass of water in his hand. His expression shifted from surprise to concern as he took in Sunoo’s unsteady stance.

“Hey,” Sunghoon said gently, setting the glass down and reaching out to steady him. “You should be resting. The fever’s not fully down yet.”

Sunoo’s grip on his sleeve tightened, fingers clenching the fabric. “Don’t leave me again.”

Something unreadable flashed in Sunghoon’s eyes—guilt, maybe, or determination. He pulled Sunoo closer, arms wrapping securely around him. “Never,” he murmured into his hair. “I was just getting us some water. You’re dehydrated.”

Sunoo let himself sink into the embrace, his head fitting neatly under Sunghoon’s chin. The alpha’s scent enveloped him—cool and familiar and safe. But beneath that, something sharper, something almost predatory, hovered.

He pulled back just enough to look up at Sunghoon, searching his face. The alpha’s gaze was steady, but there was a new intensity in his eyes, a barely contained energy that hadn’t been there before.

“What’s wrong?” Sunoo asked softly, his thumb tracing the line of Sunghoon’s jaw.

Sunghoon caught his hand, pressing a kiss to his palm. “Nothing you need to worry about. Just focus on getting through this, okay?”

But Sunoo was already shaking his head. “No, you’re not—you’re—” He broke off, frustrated, and leaned closer, inhaling deeply. There it was again, that sharp edge of pheromones that didn’t match Sunghoon’s usual calm. “Your rut—”

“It’s nothing,” Sunghoon interrupted firmly, his hand sliding up to cradle the back of Sunoo’s neck. “Just the scent of you in heat. It’s… affecting me. But I can handle it. You’re my priority.”

Sunoo swallowed hard, guilt twisting in his stomach. He’d never intended for this to trigger Sunghoon’s rut, not when he needed the alpha’s clarity, his steady control. “I’m sorry. I didn’t mean—”

“Don’t apologize.” Sunghoon’s grip tightened, just shy of being too much. “This is what mates are for. I’ll take care of both of us.”

Despite his words, there was a tension in him now, a coiled energy that hadn’t been there hours before. Sunoo could feel it in the rigid set of his shoulders, in the way his fingers flexed against Sunoo’s skin. It was subtle, but unmistakable—a restlessness that spoke of needs unmet.

“Sunghoon,” Sunoo started, then hesitated. His own needs were overwhelming, his heat still simmering beneath his skin, but there was room for something else now. A different kind of warmth.

The alpha’s eyes met his, sharp and intense. “What?”

“I know this isn’t easy for you,” Sunoo said softly. “The rut coming on so suddenly. But I want you to know—you don’t have to hold back. Not with me.”

Sunghoon’s breath caught, the sound so quiet Sunoo nearly missed it. “Sunoo…” His voice was low, almost warning, but there was an edge of something else there too. Desire, maybe, or need.

Sunoo stepped closer, closing the distance between them until their bodies nearly touched. “Let me help,” he whispered, reaching up to trace Sunghoon’s lips with his thumb. “Let me take care of you too.”

For a long moment, Sunghoon didn’t respond. His gaze flickered over Sunoo’s face, searching, almost cautious. Then, slowly, he leaned in, his forehead resting against Sunoo’s.

“Are you sure?” he murmured, the words warm against Sunoo’s mouth. “You need to rest. You need me to look after you.”

“I am resting,” Sunoo insisted, ignoring the tremor in his legs. “And I’ll keep resting. But right now, I want this too.”

Sunghoon pulled back just enough to study his face again, his expression unreadable. Then, with a soft sigh, he nodded. “Okay. But we do this my way, alright? Slow and easy.”

Sunoo managed a shaky laugh. “Always so careful.”

“It’s what you need,” Sunghoon reminded him gently, before dipping down to capture his mouth in a kiss.

It was tender at first, almost chaste, just the light press of lips against lips. But Sunghoon’s control was slipping; Sunoo could taste it in the way his teeth caught his bottom lip, in the low growl that rumbled in his chest when Sunoo opened for him. His scent flared, alpha and possessive, and it sent a shiver down Sunoo’s spine.

Sunghoon’s hands moved to his hips, grip tightening as he deepened the kiss. His tongue swept in, claiming, dominating, and Sunoo arched into him with a quiet moan. The alpha’s touch was firm, commanding, but not rough—never rough. He knew how to handle Sunoo in heat, how to push without breaking.

“Good boy,” Sunghoon murmured against his mouth, the praise sending a thrill through Sunoo. “So perfect for me.”

Sunoo’s breath hitched, pleasure pooling low in his belly at the alpha’s words. He clung tighter to Sunghoon’s shoulders, anchoring himself as the alpha’s kisses grew more insistent, more demanding. Sunghoon’s teeth scraped along his jaw, down to the tender skin of his neck, where he bit down gently.

“Mine,” he growled, the vibration of the word against Sunoo’s pulse point making him shiver. “All mine, Sunoo.”

“Yes,” Sunoo breathed, his head tilting back to give the alpha more access. “Yours.”

Sunghoon made a low, approving sound, his mouth working over the bite mark, soothing the sting with gentle licks and suckling kisses. His hands roamed lower, cupping Sunoo’s ass through his clothes, squeezing firmly.

“Need you,” Sunghoon muttered, the words slurred against Sunoo’s skin.

Sunoo’s reply was lost in a gasp as Sunghoon lifted him easily, guiding his legs around his waist. The alpha carried him back toward the bedroom, mouths still connected, bodies pressed as close as possible. Every step sent a jolt of pleasure through Sunoo.

When they reached the bed, Sunghoon laid Sunoo down carefully, following him onto the mattress. His body covered Sunoo’s completely, pinning him down with delicious weight. The alpha’s mouth was relentless, kissing and biting a path down Sunoo’s throat, his broad shoulders blocking out the world.

“Please,” Sunoo managed to choke out, his fingers scrabbling at Sunghoon’s shirt. “Need you inside—”

Sunghoon shuddered against him, a low groan tearing from his chest. “Not yet,” he said roughly, biting down on Sunoo’s collarbone. “Have to make you ready first.”

Sunoo whined, hips bucking up instinctively, seeking friction. But Sunghoon held him still, his larger body easily controlling Sunoo’s restless movements. The alpha’s hands were everywhere, tugging at clothes, pushing fabric out of the way, until skin met skin.

“You’re so hot,” Sunghoon mumbled, his palm sliding up Sunoo’s bare chest. “Burned me when I touched you.”

Sunoo arched into the touch, his breath coming faster. “More. Need more, Sunghoon.”

The alpha obeyed, his mouth closing over one nipple, tongue swirling around the hardened bud. Sunoo cried out, his back arching off the bed, but Sunghoon kept him grounded, one hand splayed across his chest, holding him in place.

“Perfect,” Sunghoon growled against his skin, before moving to give the other nipple the same attention.

Sunoo writhed beneath him, pleasure sparking through his body with every touch, every scrape of teeth, every swipe of the alpha’s tongue.

By the time Sunghoon trailed lower, Sunoo was panting, his body a live wire of sensation. The alpha pushed his shirt up, exposing his stomach, and pressed a kiss to his navel.

“Beautiful,” Sunghoon breathed, nuzzling the soft skin there. “My beautiful omega.”

Sunoo’s fingers tangled in his hair, urging him lower. “Please…”

Sunghoon didn’t make him ask twice. He slid down the bed, strong hands pushing Sunoo’s legs apart, until he was completely exposed. Sunoo flushed, embarrassment warring with desire as the alpha looked his fill.

“Gorgeous,” Sunghoon murmured, leaning in to press an open-mouthed kiss to the inside of Sunoo’s thigh. “All of this, just for me.”

Sunoo whimpered, his hips twitching. “Sunghoon—”

“I know.” The alpha’s breath was hot against his skin. “I’ve got you.”

The first swipe of his tongue made Sunoo’s toes curl, a strangled cry ripping from his throat. Sunghoon was thorough, licking and sucking at the sensitive flesh, his nose bumping against Sunoo’s clit in a way that sent sparks of pleasure up his spine. His hands kept Sunoo’s hips pinned to the bed, preventing him from squirming away or getting closer.

“Alpha!” The title came out garbled, desperate, as Sunghoon’s tongue dipped lower, teasing at his entrance.

Sunghoon hummed in approval, the vibration sending fresh waves of heat through Sunoo’s body. His tongue worked him open carefully, lapping at the wetness that coated his thighs, before pushing inside.

Sunoo keened, his fingers twisting in the sheets as Sunghoon ate him out with single-minded focus. The alpha’s tongue was relentless, curling inside him, stroking his inner walls, before retreating to lap at his clit again. It was too much, not enough, everything all at once.

“Close,” Sunoo gasped, his hips straining against Sunghoon’s hold. “So close—”

Sunghoon growled, the sound reverberating against Sunoo’s oversensitive flesh. He sucked at his clit, his tongue still buried deep, and that was all it took.

Sunoo came with a wail, his body arching up off the bed, held in place only by Sunghoon’s iron grip. Pleasure washed over him in waves, leaving him trembling and boneless in its wake. Sunghoon gentled his movements, licking softly through the last pulses of Sunoo’s orgasm, before finally pulling away.

Sunoo lay panting, his chest heaving as he struggled to catch his breath. Sunghoon moved up his body, pressing soft kisses to his skin as he went. When he reached his face, the alpha nuzzled into his neck, inhaling deeply.

“You smell incredible,” Sunghoon murmured into his ear, the low rumble of his voice making Sunoo shiver. “Taste even better.”

Sunoo turned his head, catching the alpha’s mouth in a sloppy, breathless kiss. He could taste himself on Sunghoon’s tongue, salty and musky, and it sent a fresh wave of arousal through him.

“More,” he breathed, hooking a leg around Sunghoon’s hips, pulling him closer. “Need you. Inside me.”

Sunghoon groaned, his hips pressing forward instinctively, his hardness grinding against Sunoo’s thigh. But even through the haze of his own need, he hesitated.

“Are you sure? You just—”

Sunoo cut him off with another kiss, this one more insistent. “I’m sure,” he said fiercely. “Need to feel you. Knot me.”

Something broke in Sunghoon then, the last of his restraint falling away. He surged forward, capturing Sunoo’s mouth in a bruising kiss, his hands rough as they pushed his legs wider.

“Yes,” he snarled, nipping at Sunoo’s bottom lip. “Mine.”

Sunoo wrapped his legs around Sunghoon’s waist, arching up into him, begging wordlessly for what they both needed. The alpha reached between them, freeing himself from his pants, and lined up with one hand.

The stretch burned, delicious and perfect, as Sunghoo pushed inside. Sunoo’s breath caught in his throat, his nails digging into the alpha’s back as he was filled, completely and utterly.

“Okay?” Sunghoon panted, his forehead pressed to Sunoo’s, his hips sunk deep.

Sunoo nodded frantically, heels digging into Sunghoon’s ass, urging him to move. “Perfect. So perfect. Please—”

The alpha didn’t need any more encouragement. He pulled out until just the tip remained, then thrust back in, hard and deep. Sunoo cried out, head thrown back, as pleasure jolted through him.

Sunghoon set a brutal pace, each thrust driving Sunoo into the mattress, pushing him higher and higher. His hips snapped forward, the sound of skin on skin filling the room, drowning out Sunoo’s increasingly desperate pleas.

“Sungh—alpha—please!”

Sunghoon snarled, leaning down to sink his teeth into the junction of Sunoo’s neck, reclaiming his mark. The pain blended with pleasure, white-hot and overwhelming, as the alpha fucked him through the sensations.

“Mine,” Sunghoon growled again, the word muffled against Sunoo’s skin. “Always mine.”

“Yes—yours—always yours—”

The alpha’s rhythm stuttered, his hips losing their precision as he drove into Sunoo with wild abandon. Sunoo met him thrust for thrust, clinging to broad shoulders, his mouth latching onto any skin he could reach, sucking marks into Sunghoon’s neck, his shoulder, anywhere he could.

The bed creaked dangerously beneath them, but neither noticed, too lost in each other, in the desperate race toward completion.

Sunghoon’s knot was forming, catching with each inward thrust, but Sunoo needed more. He scrabbled at Sunghoon’s back, his breath hitching. “More—need more—”

The alpha growled, pulling back to look at him. His eyes were wild, pupils blown wide with lust. “What do you need?”

Sunoo’s face burned, embarrassment momentarily overriding his arousal. “J-just—more. Need to be—filled.”

Understanding dawned on Sunghoon’s face, quickly followed by determination. He kissed Sunoo hard, then reached for the bedside table. From the drawer, he pulled out a slim plug, already slick with lube.

Sunghoon pushed Sunoo’s legs up towards his chest in a new position, his entrance exposed. “This okay?”

Sunoo nodded, unable to speak, his eyes fixed on the plug in Sunghoon’s hand. The alpha pressed a quick kiss to his knee, then reached down, slowly pushing the plug inside.

Sunoo gasped at the added intrusion, his walls clenching around Sunghoon’s cock. The alpha hissed, his rhythm faltering for a moment before he regained control.

“So good,” Sunghoon ground out, picking up speed again. “So fucking perfect for me.”

Sunoo could only moan in response, his body overwhelmed with sensation. The plug added a delicious fullness, a constant pressure that made each thrust feel that much deeper, that much more intense.

When Sunghoon came, he did so with a strangled roar, his knot locking them together as he pumped Sunoo full of cum. Sunoo climaxed with him, his oversensitive body unable to withstand the combined pleasure of the alpha’s knot and the plug stretching him wide.

They collapsed in a tangle of limbs, Sunghoon careful not to crush Sunoo beneath his larger frame. The alpha nuzzled into Sunoo’s neck, breathing in his scent, his satisfaction clear in the low rumble that vibrated through his chest.

“Good?” he asked hoarsely, his lips brushing Sunoo’s skin with each word.

Sunoo hummed, too exhausted to form words. He tangled his fingers in Sunghoon’s hair, holding him close.

As they recovered, Sunghoon’s knot gradually softened, allowing him to pull out with a wet squelch. Sunoo winced at the loss, sore but sated, his body heavy with contentment.

But as Sunghoon shifted, moving to lie beside him, Sunoo felt a spark of renewed need. His heat was far from over, and he doubted the alpha’s rut had passed either. Already, he could feel Sunghoon’s cock hardening against his thigh.

“Again?” Sunghoon asked, reading him perfectly. The alpha’s voice was rough with arousal, even as concern creased his brow. “You sure you’re not too sore?”

Sunoo shook his head, rolling onto his side to face him. “Heat’s not done with me yet.”

Something feral sparked in Sunghoon’s eyes at that, his gaze raking over Sunoo’s body hungrily. “As you wish.”

This time, when Sunghoon moved to kiss him, it was Sunoo who deepened it, his tongue pushing into the alpha’s mouth possessively. He climbed onto Sunghoon’s lap, straddling his hips, the plug still filling him catching against the alpha’s stomach.

Sunghoon groaned into the kiss, his hands gripping Sunoo’s hips tightly. “Fuck.”

Sunoo ground down, a shudder of pleasure rippling through him at the pressure against his clit. He broke the kiss to look at Sunghoon, a smirk playing on his lips. “Like that, do you?”

The alpha’s eyes were dark, his breathing ragged. “You have no idea.”

Sunoo lifted up slightly, reaching between them to position Sunghoon at his entrance. Even with the plug, he was tight, but the alpha’s cum dripping out of him helped. He sank down slowly, watching Sunghoon’s face as he took him in.

“Shit,” the alpha hissed, his head thrown back, the long line of his throat exposed.

Sunoo leaned forward, licking a stripe up his neck before whispering in his ear, “All yours, alpha.”

That seemed to push Sunghoon over the edge. With a snarl, he sat up abruptly, wrapping an arm around Sunoo’s back to support him as he flipped them over, reversing their positions.

Sunoo landed on his back with a breathless laugh, his legs wrapping around Sunghoon’s waist instinctively. The alpha loomed over him, eyes blazing, before dropping his head to press a kiss to Sunoo’s chest

“Impressive,” Sunoo teased, carding his fingers through Sunghoon’s hair. “Didn’t think you could move like that with me in your lap.”

Sunghoon nipped at his jaw in retaliation. “Brat.”

The alpha pulled out slightly, then thrust back in with one smooth movement, and any reply Sunoo might have made was lost in a moan. Sunghoon set a steady pace, his hips moving in a way that had the plug rubbing against his cock with each stroke.

“So good,” Sunoo panted, meeting him thrust for thrust. “Feels so good.”

Sunghoon grunted in agreement, his pace picking up, the force of his thrusts pushing Sunoo up the bed. Sunoo clung to him, nails leaving red lines down the alpha’s back as they moved together desperately.

“Turn over,” Sunghoon growled suddenly, pulling out and flipping Sunoo onto his stomach. “On your knees.”

Sunoo obeyed eagerly, pushing up onto his knees and arching his back, presenting himself fully. The position pressed the plug snugly against his prostate, making him keen as Sunghoon thrust back inside.

The alpha leaned over him, one hand on the bed for balance, the other reaching beneath Sunoo to stroke his clit. “Is this what you wanted, baby? To be filled like this?”

Sunoo could barely speak, reduced to whimpers and gasps, but he managed a nod. Sunghoon made a low, approving sound, his thumb swiping over Sunoo’s clit mercilessly.

Pleasure built rapidly, coiling tight in Sunoo’s belly. He pressed back against Sunghoon, urging him deeper, harder. The alpha obliged, snapping his hips forward with enough force to jolt Sunoo up the bed.

When Sunoo came, it was with a wail, his entire body shaking with the force of it. Sunghoon fucked him through it, his thrusts losing their rhythm as his own climax approached.

“Mine,” the alpha snarled, sinking his teeth into Sunoo’s shoulder, just above his scent gland. “Say it.”

“Y-yours!” Sunoo sobbed, pushing back into each thrust. “Always yours, alpha!”

Sunghoon howled, his knot swelling as he emptied himself inside Sunoo. The alpha collapsed over his back, both of them panting heavily, slick with sweat. Sunghoon’s larger body covered Sunoo completely, pinning him to the bed, his knot still caught inside.

“You okay?” Sunghoon mumbled into his hair, even as he nosed at the mark he’d left on Sunoo’s shoulder.

Sunoo hummed in contentment. “Perfect.”

Sunghoon ran his hands up Sunoo’s sides, then back down, squeezing his ass gently. “Beautiful,” he murmured. “Can’t wait to take you here too.”

Sunoo shivered at the thought, his body already responding to the alpha’s touch. “Yeah?”

Sunghoon hummed, pressing a kiss to the nape of Sunoo’s neck. “Mmhm. Gonna fill you up, pretty boy. Every hole.”

The alpha’s hands kneaded Sunoo’s ass, parting his cheeks slightly to get a better view. He groaned at the sight that greeted him—Sunoo’s entrance, pink and puffy, stretched around his knot, the base of the plug just visible where it disappeared inside.

“So perfect,” Sunghoon breathed. He leaned down, pressing his tongue to Sunoo’s tailbone, then lower, into the crease of his ass.

Sunoo squirmed, his cheeks flushing at the new sensation. “W-wait—”

But Sunghoon was insatiable, his tongue delving deeper, lapping at the skin around the plug. Sunoo cried out as the alpha’s tongue brushed the plug itself, sparks of pleasure making his toes curl.

The sensation was overwhelming—Sunghoon’s tongue working him open, combined with the fullness of the plug and his knot. Sunoo didn’t know if he wanted to pull away or push back for more.

“Alpha—” he gasped, his fingers clutching at the sheets. “I can’t—”

Sunghoon ignored him, too focused on preparing him. The alpha’s tongue circled the tight ring of muscle, teasing but never quite pushing inside. When he finally did breach that entrance, Sunoo nearly screamed.

His tongue was thick and wet, stretching Sunoo just a little more. The alpha worked it in and out, his other hand coming up to play with the plug, pushing it in deeper.

“Sunghoon!” Sunoo’s voice was high and desperate. “Please—I need—”

The alpha pulled back, a wicked smile on his face as he met Sunoo’s gaze. “Need what, baby?” he purred, twisting the plug slowly. “Use your words.”

Sunoo whined, his hips pushing back instinctively. “More. I need more. Need you.”

Sunghoon leaned down to press a soft kiss to his temple. “Good boy.”

The alpha reached for the lube, coating his fingers generously before returning his attention to Sunoo’s ass. This time, when his finger pushed in alongside his tongue, Sunoo keened, the stretch of something other than the plug or Sunghoon’s cock feeling strange but good.

“So tight,” Sunghoon murmured approvingly. “Gonna feel so good around my cock.”

The thought made Sunoo shudder, fresh arousal making his clit throb. He rocked back against Sunghoon’s fingers, urging him on silently.

“Greedy,” Sunghoon teased, but there was admiration in his voice. He worked Sunoo open carefully, adding a second finger, then a third, scissoring them gently.

When Sunoo was finally ready, squirming and whimpering with need, Sunghoon pulled his fingers out. The alpha slicked his cock, then pressed the tip against Sunoo’s stretched hole.

“Ready?” he asked, even though they both knew Sunoo was more than ready.

Sunoo pushed back, impaling himself on the first few inches of Sunghoon’s cock, making them both groan.

“Fuck,” Sunghoon hissed, gripping Sunoo’s hips to stop him from moving further. “Let me—”

But Sunoo was beyond patience. He slammed his hips back, taking the entire length in one smooth motion, his scream echoing off the walls.

Sunghoon froze, his fingers digging into Sunoo’s flesh. “Shit, okay? Fuck, you feel so good.”

Sunoo panted beneath him, adjusting to the new stretch. There was a moment of stillness, the only sound their heavy breathing, before Sunghoon finally started to move.

His thrusts were shallow at first, just small rolls of his hips, but soon grew in strength and depth as Sunoo urged him on. The alpha leaned over him, blanketing Sunoo’s back, one hand snaking around to press against his lower belly.

“Feels good?” Sunghoon purred into his ear.

Sunoo nodded vigorously, his words lost in a series of breathless moans. He reached back to grab Sunghoon’s hip, pulling him closer, urging him deeper.

“More,” he managed to gasp out. “Alpha, please—more.”

Sunghoon growled, nipping at Sunoo’s earlobe. “Anything for you, baby. Anything.”

The alpha picked up his pace, snapping his hips forward sharply with each thrust. Sunoo’s toes curled at the sensation, sparks of pleasure shooting up his spine with each jolt.

“So tight,” Sunghoon praised, his voice rough with arousal. “So perfect for me. Fuck.” Sunoo could feel the tension building in his belly, a familiar tightness that signaled his impending release. He pushed back into each thrust, meeting Sunghoon’s move for move.

“Gonna cum,” he choked out, his voice barely audible. “Alpha—”

Sunghoon reached around to rub his clit roughly, the new sensation making Sunoo cry out. “That’s it, baby. Wanna feel you cum on my cock.”

Sunoo arched beneath him, his body taut as a bowstring, hovering on the edge of release. Then Sunghoon changed the angle of his thrusts slightly, and suddenly Sunoo was toppling over that edge, his body shaking violently as he came.

“S-sungh—”

The alpha didn’t let up, continuing to pound into him relentlessly. Sunoo could feel his cock swelling, the familiar stretch of Sunghoon’s knot forming.

“Gonna fill you up,” the alpha ground out, his rhythm faltering. “Fill you so good, pretty boy. Gonna get you pregnant, knock you up with my pups.”

The thought pushed Sunoo into another climax, his oversensitive body clenching down around Sunghoon’s cock as he came again. The alpha roared, his knot finally catching as he emptied himself deep inside, his cum mixing with the plug that was still nestled deep in Sunoo’s ass.

They collapsed in a heap, Sunghoon careful to keep his weight off Sunoo. He pressed soft kisses to any bit of skin he could reach, murmuring praise and affection against Sunoo’s sweaty back.

Sunoo was boneless beneath him, completely spent. He could feel the alpha’s cum and the plug filling him up, the sensation satisfying something deep in his core.

As they caught their breath, Sunghoon reached down to finger the base of the plug gently. “Want this out?”

Sunoo shook his head. “Leave it. Feels good.”

The alpha kissed his shoulder. “Whatever you want, baby.”

They lay there for a while longer, recovering and enjoying the afterglow. Eventually, Sunghoon’s knot went down enough for him to pull out, and he carefully removed the plug, causing Sunoo to whimper at the loss.

“Ssh, it’s okay,” Sunghoon soothed, rubbing his back gently. “I’ll fill you up again soon, I promise.”

Sunoo relaxed at his words, a sated smile on his face. He turned so he could snuggle into Sunghoon’s side, the alpha’s arm coming up to wrap around him automatically.

“Love you,” Sunoo mumbled, already half asleep.

Sunghoon pressed a kiss to the top of his head. “Love you”
