Work Text:

Kyungsoo stamped his feet against the soft carpet of the nursery, crossing his arms tightly over his chest. “I don’t want to go to bed, Daddy!” he shouted, his voice high-pitched and defiant. He glared at Jongin, trying to muster every ounce of stubbornness he had left.

Jongin’s arms were folded across his chest, and he raised an eyebrow to his bratty but cute little dressed in his favorite penguin pajamas. “Kitten,” he said, voice low and steady, “you know what happens when you throw a tantrum like this. I won’t let you go to your play date with Minnie tomorrow.”

“I don’t care! I’m not a baby!” Kyungsoo yelled, kicking his stuffed bear Nini across the room. His chest heaved, and he could feel the familiar mix of frustration and guilt stirring in his stomach.

Jongin took a slow step closer, letting his presence fill the nursery. “Silly cupcake,” he murmured, “you are pushing my patience. That’s why we have rules.”

Kyungsoo spun, arms flailing. “I. Don’t. Care. Mr. Kim!” He mocked, knowing his daddy had a weakness for that name.

Jongin’s gaze darkened slightly. “Princess,” he said, crouching so their eyes met, “you will stand in the corner until you can behave properly. No whining, no squirming, no arguing.”

Kyungsoo’s defiance wavered, but he planted his little feet stubbornly. “I’m not standing there!”

“Then I will make you,” Jongin said firmly. “Hands on the wall, cupcake. Now.”

Kyungsoo’s knees trembled at the sternness in his voice. Glaring over his shoulder, “This is so unfair!” he whines.

Jongin knew that while his baby would talk back and pretend to be a “bad boy” in his words, he would always follow directions and secretly enjoyed the torture.

“You will learn, my little cupcake,” Jongin said, his tone stern but controlled. “You are mine, and you will follow my rules. Otherwise…”

Kyungsoo’s stomach twisted at the implication, but the fire in him hadn’t gone out. He muttered another curse under his breath.

“Kyungsoo.” Jongin’s voice was sharp now, and Kyungsoo froze. “I will count to three. One… two…”

Kyungsoo whimpered, realizing he had no escape. “Fine! I’ll stand here!” he admitted, shoulders slumping, cheeks burning with embarrassment as he stomped to the corner of the nursery.

“Good kitten,” Jongin said approvingly. “Now, while you’re in time-out, I want you to think about your actions and fix your attitude by the time I come back.”

Kyungsoo groaned but dragged himself down to sit crisscrossed on the soft floor, pretending to reflect on his behavior. In reality, his tiny cock stirred in his jammies at the thought of his next punishment daddy had planned for him; his tantrum melted into a mix of frustration and reluctant submission.

Once he came back into the room, Jongin guided him to the small couch where Jongin usually sat while watching Kyungsoo play with his toys. “Princess, your outfit is part of your lesson tonight.” He handed Kyungsoo a soft, frilly outfit, a cute little white lace skirt that Kyungsoo’s ass always spilled out of when wearing, and Daddy’s pink sweater that drowned his baby’s body in warm wool. Kyungsoo’s cheeks burned as he reluctantly changed. He always hated Daddy’s silly outfits; he felt exposed in the confines of his own home, but whatever made Mr. happy, he would reluctantly agree to.

Once dressed, Jongin placed Kyungsoo on the couch, hands on his knees. “Now, little cupcake,” he said, “we'll go through your bedtime lesson properly. Stand still, obey, and behave. You are mine, and I will remind you why.”

Kyungsoo sighed, head bowed, feeling simultaneously humiliated and safe under Jongin’s watchful eye. Despite his defiance, he could not deny the comfort in the structure, the careful control they had perfected over the years that made everything feel… balanced.

As Kyungsoo sat stiffly on the little couch, his knees tucked together under the frilly skirt Jongin had chosen. His cheeks were still burning from his earlier thoughts. He hated how small he felt…and how, at the same time, some quiet part of him liked the structure.

Jongin stood in front of him, arms crossed. “Eyes on me, kitten,” he said. The tone was low and commanding. It made the short hairs on the back of Kyungsoo’s neck prickle up as he looked up. “Tell me why you’re here.”

Kyungsoo swallowed, moving his eyes to stare at Jongin’s feet. “Because I… threw a tantrum,” he muttered.

“And?” Jongin prompted.

“And…” Kyungsoo stared at the floor. “…I said bad words.”

Jongin crouched down until they were eye‑level. “That’s right, my little cupcake. And what happens when you break the rules?”

Kyungsoo’s voice was a whisper. “Punishment.”

“Exactly.” Jongin stood again, walked to the toy chest, and pulled out a small pink paddle. He tapped it against his palm once. “Up,” he said simply.

Kyungsoo’s breath hitched, but he obeyed, standing with trembling legs.

“Over my knee, princess,” Jongin instructed, sitting down on the edge of the couch.

Kyungsoo climbed gingerly across his lap. He knew this was part of the scene they’d agreed on, but it still made his heart hammer.

Jongin gently set his veiny hands down on Kyungsoo’s plump butt, massaging the area before the storm hit. He couldn’t help groan at the sight. His sun-kissed hands against his baby’s pale, flawless skin was always his favorite. Kyungsoo tried to hide his teary eyes behind his arms. The room felt too hot, as if it were spinning. Jongin swore he could cum just at this sight. He had to be a good Daddy, though, give his honey the punishment he deserved before he could reward him.

The paddle landed in a firm but measured smack. “This,” he said between swats and switching cheeks, “is so you remember' smack, 'Daddy makes the rules.” Another smack. “You. Do. Not. Swear.” Another. “You. Do. Not. Throw. Tantrums.”

Kyungsoo whimpered, gripping his penguin stuffed on the couch. It wasn’t hard enough to hurt, but it was enough to leave a mark tomorrow and make his eyes water even more. After a few more swats, Jongin set the paddle down and rubbed a steady hand over Kyungsoo’s arched back.

“Breathe, kitten,” he said, voice softening slightly. “What do you say?”

Kyungsoo sniffled. “I’m sorry, Daddy. I’ll be good.”

“Better,” Jongin said, still rubbing his back. “Now up. Back to the corner, nose to the wall. Five minutes.”
Kyungsoo obeyed, shuffling to the corner. He could feel the fabric of the frilly outfit brushing his legs, the echo of the spanking still tingling. He pressed his nose to the wall and stood quietly, trying to keep still.

When the timer on Jongin’s phone chimed, Kyungsoo turned around, eyes big.

Jongin walked over and lifted his chin gently. “Good girl,” he murmured, using one of his teasing food‑pet names. “My little dumpling learned to stand still.”

He led Kyungsoo back to sit down and handed a bottle of warm milk across. “Drink,” he instructed. “And while you do, tell Daddy the bedtime rules.”

Kyungsoo clutched the bottle, cheeks flushed. “No tantrums… no swearing… listen to Daddy… bedtime when told…”

“Good,” Jongin said, patting his head and taking away his now finished bottle.

Kyungsoo’s body was already buzzing at the praise, just enough to make him gasp. “Now, Kitten,” Jongin leaned in right next to his ear and murmured, his voice low and dangerous, “you’ve been teasing me all day. Why did you think you could push me and get away with it?”

Kyungsoo arched back instinctively, chest heaving. “I… I like teasing you, Daddy,” he whispered, a mix of defiance and desire shaking his voice.

Jongin smirked, gripping his hips and forcing him to stay pressed against the edge of the bed. “Good. Then I’ll show you exactly how a brat gets punished… and rewarded.”

Before Kyungsoo could respond, Jongin pulled Kyungsoo back into his lap, plush thighs on each side of him. Jongin tugged at the waistband of his little bunny’s skirt, slipping his hand down and dragging his dry index finger along his entrance, making him shiver and gasp. The combination of the spanking and the finger’s precise pressure made his body tingle in an unbearable, delicious way. “Ah… Daddy… I—” He moaned, hips bucking unconsciously, unable to stop himself.

“Shhh,” Jongin said, pressing a hand firmly to his lower back. “Not yet, kitten. You’ll have to earn every inch of pleasure.”

Kyungsoo whimpered, body trembling with need. He tried to fight the urge to beg, to push back his desperation, but the teasing strokes, the firm spanks, the tight grip on his hips, it was too much. “Please… Daddy… I… I need you…” He gasped.

“Good,” Jongin said, smacking him again. “That’s my baby. You’re going to stay on the edge until I say otherwise.”

Kyungsoo groaned, Jongin’s firm hands making it impossible to think, impossible to move. Every nerve was on fire, every inch of his body aching for release. He bit his lip, trying to hold onto control, but the desperation was overwhelming.

Jongin leaned down, voice low and possessive. “Look at me, my little brat. You belong to me. You feel every touch because I control it. You can’t move until I let you. You love this, don’t you?”

“Yes… Daddy… I love it… I… I want it…” Kyungsoo gasped, voice cracking as his body pressed back against Jongin’s hand, pushing the tip of his finger slightly into him before Jongin pulled his hand away.

“Good kitten,” Jongin said, smacking his ass again, then leaning in to take him into his mouth, tasting him. Kyungsoo arched, moaning loudly, hands gripping Daddy’s shirt, hips thrusting involuntarily. Each motion, each spank, each flick of the tongue made him shiver uncontrollably, desperate and wet.

“You’re mine,” Jongin whispered against his skin. “Mine to push, mine to tease, mine to make come exactly when I decide.”

Jongin soon pulled away and brought his hand up to his neck, slowly undoing the top two buttons of his shirt. Kyungsoo trembled in his lap. His trapped dick is grinding against Jongin’s, making him throw back his head and groan. As Kyungsoo’s Adam’s apple bobbed right in his sight line, he couldn’t take it anymore. “Up,” Jongin commanded.

Kyungsoo slowly pushed himself off his lap, legs wobbling and head turning from the constant humiliation he felt. Kyungsoo already knew what came next, so he tugged on the waistband of his silly skirt and pulled it down slowly, teasing his Daddy with every inch.

Once off, he could feel Jongin’s gaze go threw him, sending a shock straight to his stomach. His little dicklet resting against his tummy, red and begging to be played with, he could feel it pulsing against him. Precum droplets rolling down his foreskin. He was so hard his balls were slowly changing color. He couldn’t take it anymore; he didn’t even try to tease his Daddy anymore. He needed his tight, warm cunt filled to the brim. His small hands gripped tightly onto the edge of the baby pink. As he quickly pulled it off over his head, the loose fur brushed against his perky nipples, making him push out a deep groan from the back of his throat. Teary eyes locking with Jongin’s. His satisfied smirk gave his cute penguin the green light.

“On your knees. Does my baby need his paci so he can be a good boy and stay silent?” Jongin asked with a husky voice, spitting out. His pupils expanded at the thought of his pumpkin’s plush, heart-shaped lips around him. Kyungsoo rapidly nodded in excitement as he slowly descended to his knees. The bony structure against the hardwood floor had him hissing in pain.

The sight was unbelievable. Jongin’s nonchalant mask was fading as his little one sat there. Tiny hands gripping onto his plush thighs so he wouldn’t have to urge to tug on his cock, just like Daddy wanted him. Obiant and on the edge of breaking down. Jongin’s habit of not wearing underwear was cursing him as his dick rubbed against the silver zipper of his pants. The sharp pain only set his eyes on fire more.

Jongin’s hand clasped harshly around his baby’s jaw, pushing his fatten cheeks upward. Jongin gripped harder on his face, just the way he knew Kyungsoo secretly liked, and forced his fogged eyes to meet his. “Go ahead, kitten, you’ve been good enough to earn your treat now,” Jongin whispered, just loud enough for Kyungsoo to hear. Rubbing the reddened cheeks with his thumb one last time before letting go.

Kyungsoo’s jaw went slack as he faced his Daddy’s croach. His hot breath blowing on Jongin’s clothed cock earns him a moan from above. The sound was like the most beautiful thing that had ever blessed his ears, prompting him to let go of his thighs. Red fingernail marks left on his skin, burning from his grip. Small fingers trembled as he reached up to his Daddy. He pulled down the zipper of Jongin’s black slacks slowly, fumbling at the excitement of his treat.

Once open, he reached his hand down to pull his Daddy’s cock out. Kyungsoo looked up to see Jongin’s head push back against the wall, eyes shut tight and mouth silently screaming at the touch of the soft pads touching his treasures. Small curses earlier fell out of him as his little handled him.

Kyungsoo always loved his Daddy’s thick cock. It was taking up all of his vision. Tall and red, the large vein with a slight blue tint running up to his cut tip protruding out. Jongin’s hard abs hiding under his work shirt that curved into a perfect V with a tiny happy trails resting in the middle, leading the a small patch of stubbled pubic hair at his base that Kyungsoo insisted that Jongin never get rid of. The hot smell of piss and sweat that reeked slightly from the hair was mesmerizing to him. Kyungsoo swore he could cum at the sight.

He was then cut out of trance at the sound of Jongin’s foot tapping on the floor as a sign for him to hurry up. Kyungsoo jerked up and swiftly took Daddy’s cock into his hands; his hands could hardly wrap all the way around the girth. He pushed his nose straight to the base of the cock, sniffing as he raised his nostrils to the tip, his hot cheeks softly rubbing against him and giving him a light satisfaction.

“Fuck baby…” Jongin groaned out, “You really like Daddy’s cock that much, mhm?”

Kyungsoo let out a light hum as he continued to worship his dick like his life depended on it.

“Open up, ok? Let Daddy show you how to shut up and be my good little.” Jongin sternly voiced. Kyungsoo’s jaw immediately follows the command with his saliva-covered tongue slightly sticking out. He took his hands away from the masterpiece of Jongin’s dick and brought them back to his thighs.

Jongin then set his cock onto his lover's tongue, “Suck.” He commented. At the quickly wrapped his plush lips around his tip, precum seeping into his taste buds as he whiscked it around. Slightly sucking around him, not wanting to make Jongin come yet. “Stop teasing again, you brat, you want to get punished again?” Jongin stated after letting out a hiss. Kyungsoo shook his head while still rolling his tongue over his hole. Opening up his throat and taking a few more inches inside him. Bopping his head and sucking, being careful not to have his teeth graze him and get another punishment. The length stung as it hit his tonsils; more tears streamed out of his eyes.

“Come on, my sweet potato, I know you can do better than that.” Jongin snarled out, “You have to finish your treat before you can get your reward.” Kyungsoo’s doe eyes looked up to make eye contact as an acknowledgment.

Trying to shove down more, he couldn’t help but choke on the girth. Saliva spilling down his chin as he still tries to satisfy Jongin, but is still unable to take the whole length without his help. He couldn’t take it anymore, the cock down his throat, this aching butt, his eyes foggy, unable to see anything. “I-“ cough, “I can’t take anymore-“ Kyungsoo coughs out. “Help…please…” he manages to push out.

“Soo, what’s your color?” Jongin asked in a patient tone, the complete opposite of his previous sentence. He reaches down to wipe the tears off his baby’s cheeks as he waits for an answer.

“Green, Jongin, gre-“

Before he can even realize what’s happening, Jongin tightly grips the black hairs on Kyungsoo’s head and forces him down his cock until his pubic hairs are tickling his baby’s nose.

“Look at you, baby. So pretty wrapped around my cock.” his caregiver coos at the sight. “So pretty choking on me, baby. You want me to fuck your little mouth? Finally shut you up after disrespecting me?”

High off the fumes of Jongin’s dick, Kyungsoo brings his hand down to form a tight circle with his fingers at the base of his cock. He was so close without even being touched, just from Jongin’s voice, but he had to be good. He couldn’t come yet, not until Jongin said he could.

Jongin then pulls him off his dick and awaits an answer, hissing at the cold air that hits his dick. Panting, gasping for air, Kyungsoo nodded. “Please, Mr. Kim… Use me.”

Jongin didn’t have to be told twice. Forcing Kyungsoo back down on him and rolling his eyes back at the warmth. After a full minute of letting Kyungsoo adjust to the length, without warning, he roughly thrust in and out of his mouth. The round tip hit the back of his canvern with every push. The tightness of his throat had Jongin spilling out a jumble of incoherent curses while continuing to build a pace.

As his hand on his head gave out a bit, Kyungsoo knew he was close. He swirled his tongue around Jongin’s cock more, adding more pressure as he continued to fuck his mouth. Jongin’s thrust soon became jagged and uneven, his legs trembling at the familiar swell building in his lower abdomen.

“Kyungs-“ Jongin barely able to moan out this baby’s name before he was spilling down the elder’s throat. Balls slapped straight on Kyungsoo’s chin, trying to shove every centimeter of him down.

Pulling off with a pop and a hiss, Jongin looked down to see Kyungsoo. His lips were raw and abused after swallowing every last bit. Eyes red from the constant crying. Only a drop of Jongin’s release sat on the side of Kyungsoo’s mouth, which Jongin slowly wiped away with his thumb and offered to the aching hole in front of him. Kyungsoo, of course, obliged, rolling his warm muscle, coating Jongin’s finger in slaver. The tangy taste of semen had Kyungsoo moaning as he continued to inhale him.

“My Soo” the younger purred as he pulled Kyungsoo’s “favorite paci” out of his mouth. Jongin took his own veiny hands under Kyungsoo’s arms and carefully lifted his little one back into his lap, whispering sweet nothings and praises during the act. Kissing his hot cheeks back and forth while reminding him how much Daddy loved him.

Kyungsoo knew Jongin always got annoyingly sappy at the end of play time to calm down his baby and bring him back down to reality. Being the brat he is, though, Kyungsoo wasn’t done messing with him. His tight rim was still pulsing to be filled.

With his cute pout, Jongin was addicted to. Kyungsoo teases softly, “Already tired?” voice still hoarse from everything that’s happened. “I thought you said you could handle me.”

Jongin gives him a look that’s half amusement, half disbelief. “Kitten, you’re impossible.” He scoffed.

Kyungsoo just smirks, moving his index finger up, tracing slow circles on Jongin’s stomach. “Maybe. But you like it when I don’t stop,” he murmurs. “We’re not finished yet, Daddy…Baby still wants his reward.” Kyungsoo looks down, head motioning down to his still hard dick waiting to release at any moment. Before Jongin could respond again, Kyungsoo grabbed at the back of his neck and crashed their lips together. Not wasting a second before tracing his lips with his slick touch. As the slide of wetness entered Jongin’s mouth, he moaned at the faint taste of himself lingering on his baby’s lips.

Continuing to capture each other and tongues fighting for dominance, Jongin’s feathery touch gripped under Kyungsoo’s knees as he picked him up in his arms bridal style, while he swallowed every sound around them, never breaking contact. Kyungsoo moved his hands down from his neck to fiddle with the rest of the buttons on Jongin’s shirt, only to fail as his body felt like jelly in his Daddy’s arms. The kiss only grew hungrier as Jongin walked across the hall to the bedroom.

Kyungsoo muled as he felt the soft cushions of the bed surround him after being thrown in the middle of it. His pale, peachy skin glowed against the dark sheets. Back arching the comforter, legs spread wide for Jongin to fit perfectly between him as he hovered over with his hands on with side of his head. Jongin cradled himself in the crook of the elder's neck, leaving a feathery kiss along him. His top lip slid with him as he moved dangerously close to his chest. Kyungsoo’s perky nipples rose at the cool air Jongin was blowing on him. A soft “Daddy…” was whispered, begging to be touched. Jongin just hummed in response. Wanting to reward his honey bun we being so good during his punishment, he took his plump left nipple in his mouth and began to suck. He applied more pressure, curving his tongue around the areola. His right hand reached down to trace the side of Kyungsoo’s body, slightly tickling him before moving up to give his other nipple an equal treatment.

Kyungsoo was a moaning mess below him, whining at every twist and pull. He was so close, precum started to run down the side of his dick, pussy clenching, begging to be filled. Jongin knew Kyungsoo well; he knew he could come by just having his nipples played with, but Jongin wouldn’t give him that satisfaction that quickly.

Missing the touch, Kyungsoo cried out as Jongin lifted completely off of him. Jongin gave him his signature smirk, “Be a good boy and use your words, baby, I don’t want to have to punish you again, right, Soo? Tell Daddy what you want to play.”

“I-I want…”

His studders earned him a hardy smack on his plump ass, leaving a red handprint on his side. “I’ll give you one last chance.” Jongin sturnly shouted, back to using his Mr. Kim voice, “You don’t want to be punished again, hmm?” Kyungsoo responded quickly by shaking his bed against the soft pillows, messing up his already scuffed hair more.

“No! No Daddy! I want…” Kyungsoo started, his voice decrescendoing between each word, “…to play horsey with you.” His words were barely uttered by the end.

Jongin smiled at the response and leaned down to give him a kiss on the cheek before removing his touch again. “Ok, baby,” he stated as he stood up off the bed, unbuttoning the rest of the shirt with the rough pads of his finger and sliding it off his broad shoulders. He pulled his already unbuttoned pants off, leaving him bare and matching Kyungsoo. The little’s cock twitched at the sight of his Daddy’s toned thighs in front of him. “Let me prep my little cowboy first, ok?” His body comes in contact as he rests him self back in between his toy, “I don’t want horsey to hurt him.”

Then he reached over to the bedside table, grabbing the half-empty bottle of lube. The pop of the cap echoed, and a decent amount of cold slickness squeezed on the digits of his right hand. As he spread the lube around in his fingers to warm it up, Kyungsoo couldn’t control his excitement and let out a tiny squeal. Promptly gaining him another spank on his left cheek with Jongin’s dry hand.

As his index finger entered him, Jongin let out a stream of curses. “Fuck baby, your pussy is taking him so well.” The finger thrust in and out faster at Jongin continued, frothing up the lube to a white consistency. “You look so pretty, honey, like you were made for me, made for me to play around with and punish. All mine.” He emphasized the last syllable as he added in a second finger, scissoring his tight hole while just missing his prostate.

“Yes!” Kyungsoo moaned loudly. “Yes, Daddy, all yours, my pretty hole is all yours. Please-“ He cut off with a high moan as Jongin finally jabbed his enlarged glans. Pleasure ran through his veins, shaking his whole body as Jongin kept thrusting and leaning down to run his tongue on his baby’s side.

Jongin then came up to pull Kyungsoo’s leg over his shoulder, reaching deeper than before. He kissed and rubbed his cheek against the hairless calf next to him as he added a third finger inside. Kyungsoo is now a mess under his power for now, silent screams coming out of his agape mouth with every hit, his lower half burning in the heat and pain of the stretch.

Just before he could relieve himself, Jongin slowly pulled out of his slick-covered cunt, glistening and clenching at the emptiness. Usually, Kyungsoo needs four fingers to fit Daddy’s cock in him comfortably, but Jongin knew he loved the pain of his hole stretching around him. The burn made him harder whenever he became one with his love.

“Are you ready for playtime, my little adventurer?” the caregiver asked as he laid himself on his back next to Kyungsoo. He took his now hard dick into his hand, slathered it with the leftover lube, and waited for his baby.

“Yes, Daddy, I want to take a ride on my horsey toy,” Kyungsoo said, slowly becoming more confident in the act.

Kyungsoo’s hands trembled slightly as he straddled Jongin, feeling the firm weight of him beneath. His heart was still pounding from the rough play earlier, but now it was a different kind of heat, slow, deep, tender, and completely consuming.

“Are you ready, my little cowboy?” Jongin murmured, voice low and warm, his hands resting lightly on Kyungsoo’s hips. There was no pressure, no command, only the patient, possessive weight of him. “You’re in control now.”

Pushing himself down on his cock slowly, he tried to take every inch he could. Kyungsoo bit down on his bottom lip as he tried to contain his screams from the sting of his rim. Only able to glide halfway down the girth, Kyungsoo lightly tapped Jongin’s side, “Help me out a little, Daddy? He quirked.

“Don’t get too confident now, baby.” Jongin teased. With no warning, he slammed the rest of his length in this baby’s tight hole, the warmth consumed and making him growl. “Go ahead now, Daddy’s already letting you stay up past your bedtime, so use your time wisely.”

After a few minutes of becoming comfortable in the position, Kyungsoo swallowed, nerves and desire coiling together. “Yes… Daddy,” he whispered, leaning down to brush his lips across Jongin’s chest. His movements were gentle at first, tentative, testing the rhythm.

Jongin let out a low hum, chest rising and falling under Kyungsoo’s touch. “Good kitten,” he breathed. “That’s perfect… just like that. Take your time. I’m all yours.”

Kyungsoo’s hands moved to grip Jongin’s shoulders, riding him slowly, rolling his hips with a soft, measured pace. Every motion was deliberate, teasing just enough to make Jongin’s hands tighten on his hips, encouraging him to keep going. His little dicklet is springing up and down with every push. Kyungsoo started to understand why his Daddy liked being in control so much. He felt like he was going to explode.

“You feel so good, kitten,” Jongin murmured, voice rough with need. “So warm, so perfect… all mine.” His praise made Kyungsoo flush, chest pressing into Jongin, hips moving instinctively to match the rhythm of desire building between them. The newfound angle had Jongin’s curved tip hitting straight on his prostate, having him scream.

After a few bounces, he slowly became accustomed to the angle, drowning him in more pleasure. Kyungsoo leaned down, lips brushing Jongin’s collarbone, murmuring softly, “I love you… Daddy… I… I want you to feel good.” His movements became slightly faster, hips rolling with more confidence, as he realized how much he enjoyed being in control but still worshiping the man beneath him. The very man he was able to express himself around surrounded his brain.

Jongin groaned, tilting his head back. “Oh… my little… you’re amazing…” His hands roamed up Kyungsoo’s back, fingers digging into the small of his spine as he guided him, shivers running through both of them. “So beautiful… so perfect…”

Kyungsoo’s breath caught. He could feel the tight coil of pleasure building, and Jongin’s praise, warm and steady, made him lean closer, nuzzling against his chest. “Daddy… I… I’m close…”

“Take it, kitten,” Jongin said softly, voice a velvet pull. “Come for me. I’m here… all of me is yours. You deserve this.”

With that, Kyungsoo let go of restraint, hips moving freely over Jongin, every touch, every gentle press, every kiss pulling them both into a slow, shared ecstasy. The soft rhythm, the whispered encouragement, and the warmth between them made each sensation explode, riding wave after wave of pleasure together, filling his abused hole to the brim. Kyungsoo’s intense orgasm had him spurting all the way up to Jongin’s chest. The little crashed down, eyes hooded as he listened to the sound of Jongin’s fast beating heart. “Such a good cowboy,” Jongin murmured into Kyungsoo’s hair, chest rising with each shiver, arms wrapped tightly around him. “So soft… so perfect… all mine… always mine…”

Kyungsoo gasped, voice trembling as he rode the wave of release, chest pressing into Jongin’s, feeling completely claimed yet deeply cherished. “I love you… Daddy… I’m yours…”

Jongin kissed the top of his head, rubbing slow circles along his spine. “And I love you, my little kitten. You’re mine… all mine. Always.”

They stayed entwined, moving slowly as they came down together, wrapped in each other’s warmth. Kyungsoo’s body trembled softly, a satisfied heat lingering in every nerve, and he nuzzled Jongin’s chest, sighing. The intensity of the earlier rough play had melted into gentle closeness, praise, and love. He felt completely, utterly safe, adored, and claimed.

“Rest now, kitten,” Jongin whispered, arms holding him close. “Daddy’s here. Always.”

Kyungsoo closed his eyes, soft sighs escaping, feeling the lingering warmth of desire, safety, and connection, knowing that tonight, he was exactly where he belonged.

 

The Next Day

 

Kyungsoo stretched his small body in the bedroom, rubbing the crust from his eyes. The memory of last night’s tantrum and layered punishments still made him squirm with embarrassment, but he also felt a strange warmth. Even though Daddy had been strict, the routine had been comforting, and he could still remember the gentle touches, the whispered pet names, the careful way Jongin had wiped away the dried cum and tucked him in tightly with his Mr. Bunbun.

“Good morning, my little cupcake,” Jongin’s deep voice greeted from the doorway. He leaned against the frame, arms crossed, a faint smirk tugging at his lips in his shirtless glory.

Kyungsoo froze mid-stretch, a blush creeping up his cheeks. “M-Morning, Daddy,” he stammered, voice small. Despite being an adult, the dynamic made him feel undeniably small in these moments.

Jongin pushed off the doorframe and walked over, kneeling slightly so he could meet Kyungsoo at eye level. “You slept well?” he asked, his tone firm but teasing. “No tantrums in your dreams, I hope.”

Kyungsoo shook his head quickly. “No, Mr. Kim. I… I was good.”

“Good kitten,” Jongin said, ruffling his hair. “Now, before breakfast, we have a little task.”

Kyungsoo’s eyes widened. “A task? Are we still playing with Minnie Hyung today at Sehun’s house?”

“Yes,” Jongin replied, voice strict. “But first, you need to tidy the nursery. Toys in the basket, clothes folded. And remember, I will be watching. Any mess or sloppy work, and there will be… consequences.”

Kyungsoo groaned while getting dressed and walking to the nursery, but he knew better than to complain. “Yes, Daddy,” he mumbled, picking up his plush bear and arranging the books on the shelf.

As he worked, Jongin circled him, offering occasional reminders. “Careful with that, sweetpea. We don’t want you hurt, now do we?”

By the time the nursery was spotless, Kyungsoo was panting slightly from effort and embarrassment. Jongin stepped back, inspecting the room. “Very good, little dumpling,” he said finally. “You earned your breakfast.”

Kyungsoo grinned shyly, feeling proud. “Thank you, Daddy.”

Jongin’s eyes softened, but the underlying authority remained. “And remember, kitten, your bedtime lessons from last night weren’t just punishments. They’re there to help you behave and stay safe in your little world. I’m strict because I care.”

Kyungsoo’s chest warmed at the words. “I know, Daddy,” he whispered, crawling onto the rug for a playful hug. “I’ll try to be better… for you. I love you.”

Jongin chuckled, picking him up briefly and spinning him around like a giant keepsake. “That’s my little cupcake,” he said, squeezing him close. “Now go eat before I make you do an extra chore.”

Kyungsoo giggled, running to the kitchen. Even though the previous evening had been intense, he felt safe and cherished, but ready to test his Daddy’s patience just a little bit more later, knowing that every bratty moment would be met with firm, careful hands.

The nursery, the little world they shared, and the gentle structure Jongin provided had created a rhythm that made Kyungsoo feel simultaneously small, safe, and utterly adored by his Daddy.
