In Another Life, In This One Too

Summary:

Arthur Pendragon’s life was saved by a sacrifice from his alternate self—a twist of fate that left him with haunting dreams of a past life in which Merlin, his gentle and protective father, was also his lover. As Arthur grows up, those dreams become harder to ignore, and so do the feelings they awaken. Navigating high school to college, Arthur’s caught between the life he has and the one his heart remembers. Meanwhile, Merlin, the always-affectionate dad, has never turned his son down.

Pt 2 in the "A Promise Beyond Time" series. Even though the two are connected, you don't have to read pt 1 to understand (but feel free! This fic is such a fix-it). This fic takes place in a different multi-verse to the first one but it's still very much connected. Wholly different vibes.

Chapter Text

Twilight brought the worst memories—Freya’s glowing smile, her dreams of their family, her final whisper, “Love him enough for both of us.” Her labor had been long, the doctors did all they could, but she didn’t make it.

Instead, she had given him Arthur, their sweet blonde baby boy. 20-year-old Merlin found it quite curious that Arthur had come out blonde, as neither he nor Freya had blonde relatives and were both raven-haired themselves. But he merely chalked it up to the universe's way of telling him that Arthur would be his shining light in the wake of the tragedy.

 

One evening, when Arthur was one, Uncle Gaius came for a visit. As the old man sipped a warm cup of chamomile tea, he said to Merlin quite solemnly, "With all due respect to Freya, I must insist that you conduct a DNA test to ascertain that the boy is truly yours. It is highly uncommon for a couple with black hair and no known blonde ancestry to suddenly produce a child with blonde hair. According to the latest medical studies, the likelihood of such an occurrence is less than one percent."

Merlin's jaw tightened as he shot Gaius a look. "Freya has always been faithful. We have no need for such tests. Arthur is our son, and that’s all that matters." His voice softened slightly. "I love her, and I trust her completely. I don’t need some study to tell me what my heart already knows." Merlin brushed a finger over Arthur’s little nose, which already mirrored his own. “He has my nose, and Freya’s smile.” 

Gaius regarded Merlin with a steady, almost regretful look. "I understand, Merlin, but facts don’t change with feelings," Gaius said gently. "This isn’t about faithfulness—it’s biology. I just want to be sure nothing is missed. It is not my intent to cause doubt, but rather to protect both you and your son." His gaze softened, though his tone remained firm. "Please, for peace of mind, run the test. For all our sake."

"Protect us from what? He may not be mine by blood, but he is in my heart."

"Well, in case..." Gaius's voice faltered, hesitant. “In case the real father wants him back.”

Merlin’s expression darkened. “He wouldn't have any right to him, Gaius. Not after all this time. I’ve been the one raising him, loving him, being there for every tumble and nightmare. And Arthur… Arthur doesn’t even know anyone else. I’m his father.”

Gaius nodded, his gaze steady. “I don’t question that, Merlin. Not for a moment. But if someday, someone shows up—claiming a right, a title—"

"I'll fight them," Merlin cut in, eyes blazing with protectiveness. “He belongs with me. Nothing will change that.”

Gaius sighed, though there was a glint of pride in his eyes. “I know you will, Merlin. But sometimes, these battles are won with knowledge, not just conviction. Let’s have this as a safeguard. So if anyone does come forward, you’ll be ready.”

Merlin’s shoulders dropped, and he finally gave a small nod. “Alright,” he murmured. “Let’s do the test. But no matter what it says… he’ll always be mine.”

Weeks later, the words “Parentage: 99.9% confirmed” settled every doubt in Gaius’s mind as a smug Merlin handed him the test results. Clutching Arthur, Merlin whispered, “See? He’s mine, through and through. He just so happens to be a rare biological anomaly, like the little star of my life that he is.” 

 

Now, five years later, Merlin watched Arthur chase butterflies in their garden, his childish laughter carrying on the breeze. Though only 25, Merlin felt ancient some days under the weight of his grief. But Arthur was truly his light, his reason for pressing forward. He poured all his love—both his and Freya's share—into their boy.

"Papa, look!" Arthur called, holding up a flower crown he'd very sloppily tied together with string. "Mummy showed you how to make these? Can you teach me?"

Merlin's heart clenched even as he smiled. "She did, little dragon. Come here. I'll show you how, without string." He pulled Arthur onto his lap, guiding small fingers through the delicate work of weaving stems together. "Your mother was brilliant at this. She used to make them for the spring festivals."

"Tell me bout Mummy! What's she like?" Arthur requested, as he did most days. 

Merlin always honored her, sharing stories of the brave, beautiful woman who gave him their son. “She’d be so proud of you,” he whispered, kissing Arthur’s hair. “She loved you from the start. And as long as I’m here, you’ll never be without love.”

Arthur snuggled closer, small hands clutching the completed flower crown. "I love you too Papa! All the way to the moon and back!"

Merlin held his son close, breathing in his sweet, familiar scent. Arthur had Freya’s kindness, her gentle heart. The ache of losing her never faded, but loving their son was the best way to honor her.

Now, Merlin hadn’t slept in days—not since the diagnosis. He had dark circles under his bloodshot red eyes. "Stage 4 pancreatic cancer" rang in his mind like a death knell. This cancer in children was seldom seen.

Why did this have to happen to him? To his and Freya's sweet, loving little boy? He had already lost her, the love of his life. He couldn’t lose Arthur too. Not his bright boy who still made flower crowns, chased butterflies, and called him "Papa" with that tender voice.

When sleep finally took him, he dreamed.

He stood in a place of mist and starlight, where time felt distant. Before him stood a woman—ethereal, golden-haired, her blue eyes full of wisdom.

"I am Ygraine," she said, her voice heavy with centuries. "Before Arthur was your son, he was mine.”

Merlin stared at her long blonde hair and crystal blue gaze, both the exact shade of his son’s. So this is where Arthur got his mysterious blonde hair, he found himself thinking. 

She went on, “I am here now because a father's grief transcended worlds. You and your son’s love is one of legend—continuously recycling throughout the ages. A love so deep, it defies time itself."

"I don't understand," Merlin whispered, his voice breaking.

Magic shimmered in the air, reality bending to her words.

"Love is the strongest force," Ygraine said. "From the moment your souls connected, you and your son formed a bond that echoes across all lifetimes. Your love ties you together beyond time and space, a spark that never fades. Nothing can break it—it will endure, always."

 "Please, ma'am, my son is dying-"

"In another world, another timeline, your son died of this same cancer," Ygraine cut him off gently. "And your grief—oh, your grief was so profound it shattered the veil between worlds. Your love for him was so pure, so desperate, it reached across the multiverse itself." 

With a wave of her hand, Merlin felt his knees buckle as images flooded his mind—another version of himself cradling a lifeless skeletal Arthur, screaming his agony to uncaring skies, his magic exploding outward in waves of uncontrolled anguish. Images of a dying boy, far weaker and more fatigued than his own—getting thinner with each passing day, sunken yellowed eyes, sallow skin, a swollen abdomen, puking, continuously in pain. The other version of himself, crying himself to sleep each night, eyes always red and swollen from non-stop tears. 

"Your pain in that world created ripples," Ygraine continued, reaching out to steady him with hands that felt like starlight. "Fate itself was moved by your suffering. It was too late for that Arthur, but not for yours. Not this time."

"You mean-" Merlin could hardly dare to hope.

"Your son will live, Merlin. The cancer will go into spontaneous remission. The doctors will call it a miracle, but it is simply the universe balancing itself, granting the desperate wish of a father who loved his son so much that his grief could bend reality. For to give life, a life had to be taken."

Tears streamed down Merlin's face. "Thank you," he breathed. "Thank you."

"Love him," Ygraine smiled, already beginning to fade. "Love him enough for all the fathers across all the worlds who lost their Arthurs too soon."

Merlin awoke with a start, tears on his cheeks and hope in his heart. That had felt too real to be just another dream. But could it really be?

 

Two weeks later, attending personnel were amazed by Arthur's inexplicable recovery. Merlin held his son close and silently thanked the other version of himself whose love had saved their boy.

That night, as Arthur slept peacefully in his bed, Merlin whispered to the stars, "I'm so sorry you lost him. I promise I'll give our Arthur all the love you couldn't give yours. Thank you for saving him."

Somewhere in the multiverse, Merlin swore he felt an answering pulse—bittersweet joy and gratitude. At least somewhere, Arthur lived.

 

Thunder rumbled, and Merlin heard small feet racing down the hall.

"Papa?" Arthur whispered, clutching his stuffed dragon. "Can I sleep with you?"

Merlin lifted the covers. "Come here, little dragon."

Arthur scrambled in, curling up against Merlin’s chest. His messy blonde hair tickled Merlin’s chin as he pressed closer with every thunderclap.

"I've got you," Merlin murmured, holding him tight. "You're safe."

Storm or not, Arthur would have ended up here anyway—it had become their quiet ritual since his miraculous recovery. And Merlin wasn’t about to stop it. How could he, when each breath against his chest, each tiny snore was a gift he'd nearly lost?

During the day, Arthur was his constant shadow. Merlin never minded Arthur’s clinginess. In fact, he cherished it—whether working with Arthur in his lap, eating meals pressed together, or watching him run back for hugs at the park, he soaked in each and every moment.

"Papa?" Arthur mumbled sleepily against Merlin one night, while being tucked in against his father’s chest.

"Yes, love?"

"I love you infinity times infinity."

Merlin kissed Arthur’s forehead, smiling. “I love you infinity times infinity plus one.”

Arthur giggled sleepily. “That’s not fair! You can’t go higher than infinity times infinity.”

“I’m your papa—I can do anything,” Merlin teased, stroking Arthur’s now-healthy hair.

As Arthur eventually drifted to sleep, Merlin held him close. Let Arthur cling as long as he needed. Let him never outgrow these precious moments. Every night with his son, feeling his heart beat against his chest, was a miracle Merlin would never take for granted.

"Thank you," he whispered into the darkness, a prayer to Ygraine, to fate, and to the other Merlin who had loved so fiercely. "Thank you for letting me keep him." 

As if in response, Arthur snuggled closer in his sleep, gripping Merlin's pajama shirt, and Merlin’s eyes grew damp with joy. His clingy, sweet, perfectly alive little boy was all he'd ever need.

 

Seven-year-old Arthur didn’t understand why he dreamed of a time when he and his father were… different. In these dreams, Arthur and Merlin were older. He saw himself taller, bigger, and stronger, almost like a protector, with Merlin by his side. Merlin was laughing, and there was the same natural closeness between them that he'd always known. 

At first he'd thought these were simple dreams, but they kept coming, night after night. It was never the same scenes, but always him with his Papa. He dreamt of riding through misty forests, standing side-by-side on mountaintops—him as a king and Merlin, his best friend. They fought off magical beasts and shared everything—secrets, fears, dreams.

Some moments made his cheeks burn. His Papa looked so handsome from the perspective of Dream him. He wanted to kiss Papa but never worked up the courage. He was confused why Dream Arthur was so afraid. He kissed Papa all the time and it was okay! Plus Dream Arthur was a king! Kings weren't afraid of anything. 

Arthur despaired that he couldn't control what Dream him did. He could only continue joshing about with Papa, moving a little too close, a hand here, hand there, but with no move to kiss him. 

One morning, Arthur sleepily curled into Papa's lap at breakfast. "Papa," he started. "Do you ever get the feeling we've known each other before?"

Merlin's breath caught. He wondered if Arthur, too, had been visited by Ygraine. Holding him close, Merlin kissed his temple, murmuring, "I believe we've always been close. Deep down, we've always been together."

Arthur nodded vigorously. "In my dreams, we were the same age! And I was bigger than you! We always do everything together. Feels right, Papa.”

Merlin smiled softly, his fingers brushing over Arthur’s hand. “That’s because it is right.”

So his son had not been visited by the ethereal Ygraine. Merlin brushed a stray hair from Arthur’s forehead. "We're bonded, Arthur. We've always had something special. Dreams or reality, it's always us," Merlin confirmed softly.

Arthur felt the truth in his papa’s words. Even if he couldn’t explain it, he could feel the everlasting love and devotion that bound them together, a tie deeper than even blood, one that ran soul deep. 

One night, when Arthur was ten, he climbed into bed with his dad as usual. Merlin wordlessly shifted, wrapping an arm around him. They lay there quietly, the comfortable silence saying everything.

After a while, Arthur broke the quiet. “I keep having those dreams, the ones where we’re best friends but older.”

Merlin smiled softly. “Those dreams just remind you of how close we are, Arthur. You’ll always feel this connection.”

Arthur looked up at him with adoration. “Yeah,” he said, leaning in to kiss his father like they always did. “I don’t want to lose this.”

Merlin squeezed his hand. “You never will, Arthur. You’re always with me—forever.”

Arthur smiled, leaning on Merlin’s shoulder. “Good. Because I can’t love anyone else like I love you.

At thirteen, Arthur stood in a misty forest, heart racing, in a dream that felt real. He felt the sword, the cool night air, and Merlin by his side. They had just won a tough battle, tired but victorious and laughing.

Merlin stepped closer, blue eyes bright. Without words, he cupped Arthur's face and pulled him in, their breaths mingling. The kiss was firm and familiar, a feeling Arthur knew but couldn't name. Their closeness felt natural, and Arthur leaned in, hand on Merlin's shoulder, overwhelmed by their connection.

The world faded, leaving only Merlin’s warmth and their unbreakable bond. But the moment ended quickly.

Arthur woke, heart pounding, disoriented and flushed from the dream. Merlin’s touch and their connection lingered, refusing to fade. He breathed deeply, trying to steady himself. It was just a dream, but the emotions were powerful and confusing.

A pang of longing hit him. He pressed his face into his hands, hoping to push the feelings away, but Merlin’s memory stayed vivid, stirring something he couldn’t understand

Arthur shifted, trying to will away his arousal, but Merlin’s warmth made it worse. His heart raced, confused by his body’s reaction. He looked at his dad, asleep and calm.

A feeling of longing hit him. He lay on his back, rubbing his face in a sad attempt to rid himself of the dream. But the memory of Merlin’s touch and the damn feelings wouldn’t fade.

Arthur took a deep breath, trying to calm down. It was just a dream, but it left strong, confusing feelings.

Merlin shifted in his sleep, his arm across Arthur’s chest. It felt familiar, but tonight it felt different. Arthur leaned into the warmth, remembering the closeness from the dream.

Again, Arthur felt himself grow hard. Fuck, Dad, why do you do this to me? The dreams had always felt real, but never this vividly. Tonight, it felt like he’d been pulled back into a moment he couldn’t quite remember but also couldn’t let go of. 

“Dad? Are you awake?” Arthur whispered, a little unsure, though he didn’t want to disturb Merlin. When there was no response, he relaxed back into the silence, moving to rest his head on his father’s chest. He allowed his breathing to sync with Merlin’s. 

He closed his eyes, but sleep didn’t come easily after that. All he could see was Merlin—Merlin’s face close to his and the warmth of his embrace.

 

17-year-old Arthur stood in front of the bathroom mirror, splashing cold water on his face to shake the lingering fog of his dream from last night. As he wiped his face dry, his mind drifted back to Merlin. 

Arthur shuffled into the kitchen, hoping for a quiet breakfast to help clear his mind of last night’s dreams—visions, whatever the fuck they were. 

But there was his quirky hipster dad, Merlin, already sipping coffee at the breakfast table and working on his laptop, looking impossibly alert and bright. Arthur blinked. He found himself glancing at his dad more often than he cared to admit. 

Arthur found it endlessly fascinating how young his dad looked, especially for a 37-year-old. It was like someone had accidentally swapped him out for a first-year uni student. Merlin’s lean frame and bright color block fashion style only added to the illusion, regularly causing others to mistake them for brothers. Merlin had long since stopped correcting them, finding it easier to play along with a grin.

Despite the quirky clothes, Merlin was surprisingly muscular, like he could easily join Arthur’s rugby practice, though Arthur couldn’t picture him actually joining in a game. His nerdy dad was so the opposite of a jock.

Merlin had his usual messy, short black hair that looked like he’d just rolled out of bed, but Arthur knew he’d styled it that way. His dad was a total nerd about style. Merlin's blue eyes practically glowed, especially behind those wide-rimmed yellow glasses.

Arthur strolled into the kitchen, all easy confidence in his loose black-and-white Nike sweatpants and a fitted red-and-gold Camelot jersey. Merlin’s gaze caught on the relaxed fit of the sweats, the way they clung just right, and he had to swallow a sudden rush of fondness mixed with something else he couldn’t quite name. Merlin flashed a big, lopsided grin. 

“Morning, kiddo!” he greeted cheerily. Merlin slid a colorful bowl across the table. "Breakfast of champions for my little rugby player," he said, motioning to all the food. 

Arthur's eyes widened at the spread, the smell of roasted veggies, tofu, and garlic filling the air, and as he inhaled deeply, his stomach growled. “Smells amazing, Dad!” Arthur exclaimed.

Merlin chuckled, watching him fondly. “Dig in, champ. You’ll need all the strength you can get.” 

Grinning, he said a quick, “Thanks Dad,” before shoveling as much of it as quickly as he could into his mouth, while sneaking furtive glances at his dad, unable to stop thinking about the dream. 

How his dad had looked beneath him, all mussed hair, glassy-eyed, flushed cheeks.. He hated that he knew exactly how his father looked underneath all his clothes. Because he’d been underneath him just last night—

Arthur’s cheeks burned. He irrationally worried that his dad was a mind-reader. Ah, shit. Well, they were only dreams, right? No matter how vivid and realistic they felt, it didn't mean anything. 

Merlin watched him with glowing eyes. "Easy there, tiger," he laughed, shaking his head. "Just 'cause I know the Heimlich doesn’t mean I’m eager to use it. Tad early for that, innit?”

Arthur slowed down, not realizing how quickly he’d been eating. “Noted. No choking. Got it.” He managed a grin, trying to hide his embarrassment. He was painfully aware of Merlin’s eyes on him. Merlin’s gaze made Arthur more nervous.

After they ate, Merlin sipped his coffee. Arthur felt shy, something new for him. He usually gave his dad a quick peck goodbye, but today it felt different. He leaned in, kissed Merlin softly, and lingered a moment longer than usual.

Merlin laughed quietly, resting a hand on Arthur's shoulder. “Have a good day, alright?” His voice made Arthur’s heart race.

Arthur nodded, muttering, "Yeah, you too, Dad," before grabbing his bag and practically bolting.

 

Arthur walked through the crowded halls of Camelot High and spotted Gwaine talking to Lancelot and Gwen by a locker. They turned when they saw him.

“Hey, Arthur!” Lancelot called, grinning. “Ready for another day of torture on the field?”

Arthur rolled his eyes. “You mean practice? It’s character building,” he said, slinging his bag over his shoulder.

Gwaine laughed, slapping Arthur’s back. “Character building? More like a bunch of injuries followed by a visit to sexy nurse Ms. Lamia. She secretly loves it.”

“Yeah, well, she doesn’t love the aftermath of my tackles,” Percival laughed.

Arthur adjusted his jersey. “At least it’ll distract me from... other things.” He quickly looked away, his face heating up from last night’s dreams.

“Other things? Like what?” Lancelot wiggled his eyebrows. When Arthur blushed, Lancelot whispered, “It’s your dad, right? He’s got you all flustered.”

Arthur’s face burned. “No, it’s not like that!” he quickly said, but his voice gave him away. He stared at the ground as they walked.

Lancelot laughed. "Oh, please! You totally get frazzled when he's around. It’s obvious, mate.” He nudged Arthur playfully. “I mean, how could you not? Merlin’s just... well, Merlin. That hero worship you’ve got going, man.”

“Yeah, that’s all this is. Hero worship. Don’t call it a crush! That’s just.. wrong,” he muttered.

“It’s adorable, really—but I don’t blame you,” Morgana sighed, feigning wistfulness. “Honestly, Arthur, if Merlin weren’t your dad, even I’d be tempted. Those muscles, that messy hair… he’s totally hot.”

Arthur’s face turned bright red, and he spluttered, “Morgana! That’s my dad we’re talking about!”

She gave him a wink. “Just saying, you’ve got some good taste. But lucky for you, my desires lie in teasing you, not stealing your daddy.”

Lancelot burst out laughing, clapping Arthur on the back. “Guess Merlin’s got quite the fan club,” he joked.

Arthur buried his face in his hands, muttering, “I can’t with you guys.”

The prom was announced with much excitement, posters plastered around Camelot High, each one more vibrant than the last. Students milled about, chattering excitedly about the upcoming prom as Lancelot stood by Gwen’s locker, nervously hiding a bouquet of white roses behind his back.

"Gwen!" His voice cracked when she approached.

She had textbooks pressed against her chest. "Lancelot? What are you doing here? Isn't your history class across the school?”

"I, uh..." He scratched his neck. "Remember when we were kids, and you said you wanted a knight in shining armor? Well, I was wondering... since this is our final year"—he presented the flowers, bowing with a flourish—"if you would allow this knight to take you to prom?"

Gwen blinked, covering her mouth with her hand in shock, then laughed delightedly. “You want to go with me?”

"Of course," Lancelot said quickly, cheeks pink. "You're amazing. You’re beautiful, kind, who wouldn’t want to go with you?"

Gwen blushed, bashful now. "Well, in that case... Yes, Lancelot. I’d love to go with you.”

Lancelot grinned, excited. “Great! That’s... great.” He almost tripped as he walked off, while Gwen shook her head, smiling.

 

Gwaine leaned against Morgana’s locker with his signature smirk. “So, gorgeous, got a date to prom yet?”  

Morgana raised a brow. “Why? You offering?”  

He twirled a rose between his fingers. “I’m just saying, out of all the poor souls I could bless with my company, you’re the only one who could actually keep up.”  

She smirked. “Flattering yourself again, are we?”  

He held out the rose with a wink. “Let me take you to prom and I’ll spend the whole night flattering you instead.”

Morgana took the rose as she eyed him. “Fine,” she said. “But if you embarrass me, I’m leaving you on the dance floor.”  

Gwaine grinned, unfazed. “Deal. But fair warning—I plan to make us the hottest couple there.”  

She rolled her eyes but couldn’t hide her smile. “You wish.”  

“Oh, I know.” He winked. “See you at prom, princess.”

 

Meanwhile, with Arthur, throughout the day, girls one after the other asked him to prom, only to be politely but firmly turned down. 

While his friends joked about how charming he was or how “every girl in school was into him,” Arthur couldn’t shake the nagging feeling that he wasn’t ready for the pressure of a date night, which prom essentially was. 

As another girl walked away, her face flushed with mild disappointment, Lancelot nudged Arthur with a grin. “Look at you, Mr. Popular. You’ve turned down at least five dates in the last hour alone!”

Arthur groaned, running a hand through his hair. “I don’t know, Lance. It’s just… the idea of prom, of a date. It’s too much pressure. Everyone expects it to be this perfect, romantic night, and I just don’t… feel it.”

Gwaine smirked, leaning against the lockers. “Not feeling it? Arthur, you’re the school heartthrob. You’re supposed to thrive on this attention!”

Arthur rolled his eyes. "I’m not trying to be a heartthrob, Gwaine. I just wanna have fun with my friends. Prom should be… I don’t know, fun. Not this huge stressful ordeal.”

He knew people went with their friends, but going to the prom always felt like more to him. Besides, this year his mind was too consumed with thoughts of his dad and the bizarre, confusing emotions he was grappling with since his dreams had begun growing more intense. The vivid dreams, the way his pulse quickened when his dad smiled at him—how could he go on a date when all he could think about were the dreams and.. his dad? 

 

As Arthur lay in bed later that night, Merlin grinned, saying, “Goodnight kiddo, sweet dreams.” 

Arthur forced a strained smile, knowing what he’d see in his dreams. He had no control of what he did in them. It was as if he were watching a very intense adult film. “Night, Dad.”

The moment Arthur closed his eyes, he opened them again just as quickly and was face-to-face with Merlin, younger, grinning so lasciviously up at him. The dream felt almost too real. In it, he was on top of a naked Merlin. 

Oh gods, Merlin…. All milky white, bare skin, toned, so warm and smooth against his own nakedness. Arthur looked his fill. Then he was kissing Merlin, feeling every inch of his dad’s body, moving deep inside him, letting out guttural moans as he hit Merlin’s sweet spot over and over again. 

“Love you so much, Merlin,” he moaned.

“Shut up and prove it,” Merlin huffed, biting his ear.

The atmosphere shifted as they leaned in closer, the dream giving way to something deeper. Merlin’s hands found their way to Arthur’s waist, driving him deeper inside, groaning loudly with each thrust. Their breaths mingled in the charged space between them. Time felt suspended as Arthur felt the heat radiating from Merlin’s body, a magnetic pull drawing them together.

In the dream, every touch made Arthur's skin tingle. He felt the warmth of Merlin’s hands and their kiss sent shivers through him. It was passionate and tender, leaving him breathless and wanting more.

It felt so right, like they fit together perfectly. But just as it got intense, he woke up, heart racing, still feeling the dream.

He realized he was humping his mattress, and that he’d spilled. He’d lost count of how often he had spilled his seed to the dreams of fucking his father now.  The dreams always left him breathless and wanting more, feeling both exhilarated and deeply confused. Why was he having these god-awful yet intoxicating dreams?

Arthur lay staring at the wall, attempting to catch his breath. He turned to the other side, hoping to somehow get back to sleep, but his dad was already awake, watching him with dark, intense eyes. Immediately upon realizing his son was awake, Merlin broke into a goofy grin whilst Arthur got an internal jump scare.

“Hey, sleepyhead,” Merlin said, strained voice attempting playfulness. “You were having quite the dream.”

A rush of embarrassment flooded him. “I—uh, you weren’t supposed to hear that!” he stammered. He pulled the covers up to his chin, hoping the ground would open up and swallow him whole.

“It’s okay kiddo, you can’t control your own dreams,” Merlin placated. “You just woke me up is all.”

Merlin had been woken to Arthur moaning, "M-Merlin…! Fuck—" and also by how vigorously his son had been moving atop the bed.

Arthur was sweating buckets. He knew his dad was a deep sleeper. Once he was out, he was out cold. So how loud was I?! Arthur was afraid to ask what exactly his dad had overheard. 

Merlin went on gently, tone soothing, “Dreams can be strange and complicated. You don’t have to be embarrassed by them.”

Arthur’s heart raced at the softness in his dad’s voice. “It’s just… I didn’t expect to wake up and see you there, watching me like that,” he croaked. 

Merlin smiled kindly. “Must’ve been quite the shock, but I get it—you had a moving dream. Just know it doesn’t change anything between us.”

Arthur swallowed hard. “Thanks, Dad,” he whispered, biting his lip. It may not change anything for his dad, but all the repeated sex dreams had stirred something deep within him, igniting a flame that was becoming harder to ignore. 

 

Arthur was sprawled out on one end of the sofa, and Merlin, legs tucked up, on the other with a cup of herbal tea in hand. The TV was on, but neither was really paying attention as they chatted easily together.

Arthur could feel his heart racing as he fidgeted with the hem of his shirt. It’d been a week of building up his courage and well.. pining. He’d practiced what to say, but with his dad there, his words vanished in a rush of anxiety.

Merlin noticed him fidgeting and raised an eyebrow. “You look like something’s on your mind,” he said, setting down his tea. “Spit it out.” His usual open, kind "dad look" was reassuring, but tonight, it only made Arthur more nervous.

Arthur swallowed, his throat tight as he forced himself to meet Merlin’s gaze. “Yeah… yeah, I do,” he muttered. “Dad, um, I wanted to ask you something,” he started, trying (and failing) to sound casual. Imbecile, this is just your dad. This isn't some pretty girl you’re asking out!

“What’s on your mind, kiddo?” Merlin asked, in his usual easy and inviting voice. He tilted his head slightly, large wide-rimmed glasses catching the light. Merlin noticed the nervous signs—fidgeting hands, darting eyes, and how his son struggled to speak.

Arthur took a deep breath, speaking in a rush, “Will you go to prom with me? I know it sounds strange, but no one will know you're my dad. You look young enough, and it would be… fun!” Arthur’s cheeks were flushed a deep red, brighter than Merlin had ever seen.

Merlin raised an eyebrow, taken aback. “Prom? With me? Why not one of your friends? I know you don’t lack in that department, my little rugby MVP.” Merlin was now grinning proudly. 

More confidently, Arthur feigned nonchalance, “I just thought it’d be cooler to go with you. You make everything more fun, and I really want to spend that night with you. Plus, you actually know how to dance!” 

Merlin chuckled, seeming to consider it for one heart-wrenching moment as Arthur waited anxiously, sweating. “Sure buddy, I’d be honored to go to the prom with you,” he replied coolly.

Arthur grinned, relief flooding him. “Really? Awesome! It’s gonna be so much fun!” The thought of walking into prom with his dad by his side gave him butterflies.

“And just think,” Merlin said, leaning back with a grin, “if anyone tries to hassle you, I can bust out my ‘dad voice’ and scare them off.”

Arthur snorted, shaking his head. “Yeah, because nothing says ‘cool date’ like a dad voice. But good to know you’ve got my back.” 

“Always,” Merlin replied solemnly, smiling.

Feeling a rush of affection, Arthur wrapped his arms around his dad, pulling him into a hug. “Thanks, Dad. This really means a lot to me.” 

Merlin felt something warm in his chest as he hugged Arthur a little longer. "Prom's a big deal, and if you want me to be there, I wouldn't miss it for the world." 

Arthur grinned, pulling back to look his dad in the eye. "Just make sure to wear something cool! Leave the dorky PJs for the after-party."

"But those PJs are legendary!" Merlin lamented in mock horror. "But fine, I'll try to find something less dorky." He tousled Arthur's hair affectionately. 

"Good luck with that," Arthur chuckled.

Merlin laughed. “Just remember, I expect a proper dance and some corny prom photos.” 

“Of course! I’ll make it an unforgettable night,” Arthur promised. The idea of spending prom night together filled Arthur with the first real excitement all week.

Chapter Text

Finally, prom day was here and Arthur felt rather apprehensive about the big night. He was sitting with his usual group of friends in the cafeteria, all chatting about the night ahead.

“C’mon, Arthur, prom date is TO-DAY!” cried Gwaine. “Who are you going with?” 

Arthur only smirked. “That’s right, it is today, innit? Well then, today you all shall find out…” 

His friends leaned in eagerly. “..at the prom,” he finished, to a chorus of groans. 

“Is she supposed to be a big surprise?” Lancelot asked thoughtfully. 

“Duh,” Arthur snickered. 

Mordred chuckled. “Ten quid says he’s actually dating someone and keeping it under wraps.”

Morgana leaned in closer, eyes wide. “Oh my god, Arthur, is it true?” And nearly shrieking, “You’ve started dating someone?”

The surrounding students looked over, surprised by the outburst. Arthur immediately shushed her. “No! Nothing like that! Gods, Morgana, way to make a scene,” he rolled his eyes.

Gwen, eyes sparkling with excitement, continued with the interrogation, “Is it someone we know then?”

Arthur felt his cheeks heat up slightly. “You might say that.” He glanced at Gwaine, who was practically bouncing in his seat. 

“Oh, come on!” Gwaine exclaimed, throwing his hands up in exasperation. “You can’t just drop a bomb like that and expect us to not go crazy!”

Elyan joined in, smirking. “Is it one of the teachers? Because that would be wild.”

Mordred chimed in with a sly smile. “I bet it’s someone who’ll make us all jealous. You always attract the hottest chicks."

“My date is rather spicy, but otherwise you’re all so off,” Arthur laughed. Thinking about Merlin, Arthur felt a warm excitement—this prom would be different. “Trust me, it'll be worth the wait.”

Percy leaned in, mock-serious. “Okay, but if it’s not a ‘hot MILF’ surprise, I’ll be crushed.”

Arthur rolled his eyes, grinning since Percy wasn’t far off. “Don’t worry, you’ll all be pretty surprised.”

Leon laughed, clapping Arthur’s shoulder. “If you’ve really got a secret girlfriend, this would be the perfect time to tell us, you know.”

Arthur bit back a laugh. “Maybe I do. Maybe I don’t. But either way, tonight you can all see for yourselves.” 

The group groaned and rolled their eyes, laughing.

 

Finally, prom night arrived. Arthur and Merlin walked toward the venue, the air buzzing with excitement, music, and laughter.

Arthur wore a navy suit that showed off his athletic build, a dark silver-gray tie, and black, ethically made dress shoes that his dad would approve of. He felt a rush of confidence as he took Merlin's hand. Merlin, who was looking effortlessly handsome and striking, as always.

Merlin wore a beige jacket over a crisp sky-blue shirt, paired with bold yellow pants and a matching tie. His beige dress shoes pulled it all together—a look that was colorful, quirky, and effortlessly him. He blended right in with the students.  

Arthur, blown away, pressed a lingering kiss to Merlin’s lips, breathing in his Dad's sharp cologne. Merlin’s breath hitched, his heart skipping at the tenderness of it and Arthur pulled back slightly, smiling. 

His father smirked. "Keep this up, and I'll be blushing all night." Merlin rubbed his neck, trying to act cool, but he had to admit the moment felt more intense than usual.

Arthur grinned, kissing the back of Merlin's hand delicately. "Fair’s fair—you’re the one who'll be turning heads." He winked flirtatiously. 

Merlin chuckled, cheeks warming. "Careful kiddo, or I’ll need a fan."

"Ready, Dad?" Arthur only asked, smiling a small secret smile. He was thrilled to have made his dad blush.

"Lead the way, Prince Charming," Merlin replied, mischievous twinkle in his eyes.

As they entered the prom, the music and lights surrounding them, Arthur’s group, upon catching sight of the pair, went silent, staring in open-mouthed shock.

“No way!” Gwaine exclaimed, jaw dropping as he pointed a finger at them. “Is that Arthur’s dad? What is Merlin doing here?”

Gwen's eyes widened in realization. "Oh my god! Is that really Merlin?" She giggled, blushing slightly.

Lancelot blinked in surprise. "I thought he said he was taking someone special, not... that!" He pointed at Merlin, who stood confidently next to Arthur, arm around his son's shoulders.

Arthur waved when they spotted him, and the pair crossed over. Once they arrived, Morgana smirked, leaning in closer to Arthur. "Wow, Arthur, you really went for it. Your hot DILF dad is here. How'd you pull that off?"

Arthur rolled his eyes but couldn't help smiling. "Yeah, yeah, laugh it up. He's my date for the night." He tried to play it off, and if not for the darkness of the venue, his bright red cheeks would've betrayed him.

Merlin stepped forward, smile warm and welcoming. “Hey, nice to see everyone again! I hope I can keep up with all of you tonight!”

Gwaine grinned. “Oh, come on, Merlin! Keeping up with us tonight is gonna be like trying to catch a chicken on a sugar high—you’re gonna need some serious stamina!” He chuckled, nudging Merlin playfully. 

Leon grinned at Arthur. “Dude, you seriously brought your dad as your date? You’re brave.”

“This is gonna be legendary. You’ve just raised the bar for all of us, Arthur,” Percy said with a chuckle. “How’s that going to work with all the slow dancing and stuff?”

“Watch and learn. We’re gonna have an awesome night, just wait,” Arthur replied confidently, shooting them a grin. He felt an unexpected rush of pride for having Merlin as his date, no matter the initial shock from his friends. His dad was the hottest person there! 

They made their way through the crowd, stopping to take pictures with friends, where Arthur played the role of the gentleman, offering his arm to Merlin. During photos, he struck poses that made everyone laugh. “Say cheese!” Arthur called out, leaning in closer to Merlin, their shoulders touching. 

As the slow song started, the room’s vibe changed. Arthur took a deep breath, meeting Merlin’s smile. “Now time for that dance you were promised,” he whispered into his dad’s ear. 

Merlin chuckled, blushing slightly. “Okay, okay, lead the way, I suppose.”

Arthur took his hand and led him onto the dance floor, where some of Arthur’s friends were dancing. Leon and Mithian gave them a nod and Arthur waved. Gwaine immediately took note, and Morgana laughed. “Oh my, Arthur getting down and dirty with Merlin,” she observed, clearly amused.

“Who would’ve guessed?” Elyan said to his twin, Gwen. 

Gwen’s cocoa brown eyes were sparkling as she said, “This is wholesome, stop making fun of him!

“No one’s made fun of him,” Gwaine said, though he was clearly thrilled at the sight. “Just takes guts to bring your dad to prom. Honestly, it's kind of iconic.”

“Look how proud Merlin looks!” Morgana said. 

As the father-son duo started to sway together, Merlin looked surprisingly comfortable in the role, as if we’ve done this before, Arthur couldn’t help irrationally thinking. Arthur’s gaze drifted to Merlin’s lips—always so pink and plump. From their casual lip pecks, he knew they were incredibly soft, and he found himself wondering just what would happen if…

Arthur swallowed, forcing himself to look away, trying to ignore the catcalls and laughter from his friends nearby. Their teasing voices barely registered as he tried to compose himself, cheeks heating. Not in public, gods Arthur, control yourself.

“You’re doing great, Dad,” he said hoarsely. There was a bashful smile on his face as he twirled his dad.

“Thanks, but I think you’re the real star here,” Merlin replied, smiling dotingly at his son mid-twirl. 

Mithian winked at them as she was dipped back by Leon. “I think this is a new trend. Who says prom dates have to be students?”

“Yeah, I’m totally getting my dad to come next year to the uni ball,” Mordred joked.

As the song ended, Arthur and Merlin stepped back, grinning. Cheers and whistles rang out, but Arthur only felt the warmth of Merlin’s affection.

“Okay, Arthur, you definitely win prom night with that one!” Gwaine exclaimed, clapping Arthur on the back. 

Arthur leaned in, his lips brushing Merlin’s ear. “Let me show you what else I’ve planned, Dad.” Merlin shivered, unable to help a blush creeping up his neck.

“Oh?” His heart raced as Arthur grabbed his hand and led him quickly away.

They reached the photo booth. When it was their turn, the photographer said, “Say cheese!”

“Cheese!” they called out. In the picture, Arthur had his arm around Merlin’s waist, both smiling widely.

“You look like you’re having a blast,” Arthur said, laughing as they looked at the photo.

“Can’t help it when I’m with you,” Merlin admitted, smiling adoringly at his son.

As Arthur and Merlin stepped away from the booth, a blonde girl stood waiting, arms crossed. She barely glanced at Merlin and instead shot Arthur a pointed look.  

"So, no date for prom, huh?" she asked.

Arthur sighed. “Vivian, it’s not—”  

She interrupted with a huff. “Right. Just two friends, practically glowing at each other. You could’ve been honest, Arthur.”  

Merlin shifted awkwardly, looking between them. Arthur stayed calm. “Vivian, come on. Merlin’s just… a friend. I wasn’t lying to you.”  

Vivian rolled her eyes. “Sure, ‘friend.’ Just don’t lead people on next time, okay?” She gave them one last glare before walking off.  

Arthur sighed, turning to Merlin. “So much for keeping it simple.”  

Merlin chuckled and nudged him. “Guess we do look a bit like a couple.”

Arthur smirked, just resisting the urge to kiss him. Normally he didn’t see anything wrong with it, but here in public, and as his prom date no less It would definitely appear rather sus. Leaning in, Arthur whispered, “Can you blame them?”  

Merlin laughed, cheeks pink, feeling Arthur’s breath near his ear. “Honestly? Not at all,” he whispered back, eyes full of fondness. “But if you keep looking at me like that, you'll give them even more to talk about.” Merlin shook his head and led them back to the dance floor.  

As the night went on, Arthur made sure to keep up the gentlemanly persona, offering Merlin his arm as they navigated the crowd.  He couldn’t ignore the envious glances from his peers. 

“Dude! Arthur got a hot first-year uni kid to come to prom with him!” someone shouted as Arthur snickered. 

“No wonder he rejected us..” another girl said sullenly. “Could’ve just told us he already had a boyfriend. I didn’t even know he was gay.”

When it was time for the crowning, Arthur and Merlin stood together, both nervous and excited. Arthur squeezed Merlin's hand as the music played and the crowd buzzed around them.

“And the prom royalty for this year goes to... Gwaine Macken and Morgana Pendragon!” 

Gwaine and Morgana grinned, both beaming with joy. Gwaine flashed a cocky grin as he grabbed Morgana’s hand, leading her to the front while their friends cheered. “Told you we had this!” he said. 

Morgana rolled her eyes, pecking his cheek, and Gwaine threw an arm around her as the crowns were placed on their heads. The crowd cheered, and Arthur, one of the loudest voices, felt truly proud of his friends. 

Turning to Merlin with a grin, he said, "So we didn’t win. Guess we’ll just make our own memories."

Merlin chuckled, kissing Arthur’s temple. “We already have, little prince.”

Gwaine grabbed the mic, “This calls for a dance!” He lifted Morgana up and spun her easily around, both of them laughing. As P!nk’s Raise Your Glass blasted, the whole of prom went wild. Arthur and Merlin got swept up in the crowd, the music pumping through the air. Arthur grinned, pulling his dad in  closer as they danced, the lyrics filling the moment:  

“So raise your glass if you are wrong, in all the right ways…”

Merlin laughed, spinning under Arthur’s arm. “This song’s perfect for us!” he shouted over the music. Arthur nodded, pulling him close again. They laughed and danced in sync, lost in the music. With Merlin’s hand in his and the night alive around them, everything felt perfect, better than Arthur could have hoped for.  

He eventually led Merlin to the snack table. “You need energy for dancing,” Arthur said with a grin, handing him some snacks.  

“Why thank you, kind sir,” Merlin replied with a dramatic bow. “Buy me a drink, and we’ll call it even for the night,” he winked.  

Arthur grinned, a warm feeling blossoming in his chest. “Challenge accepted,” he said. “Lemonade or soda, Mister?”  

“Surprise me,” Merlin said as Arthur grabbed cups. 

The prom lights highlighted Merlin’s seemingly eternal youthful features, and Arthur couldn’t help but feel lucky to have such a handsome dad. “It looks like everyone’s having fun,” he said, handing Merlin a cup of sparkling strawberry lemonade. “But I’ve got the best date.”

“Flattery won’t work,” Merlin grinned, raising his drink.

Arthur only winked. “Like the drink?” Voice lowering and dripping with playful charm, in his most seductive voice, he purred, “It’s sweet, bubbly, and a little tangy—just like you.”

Merlin blushed. “Oh, really? Didn’t know you were a flavor expert,” he teased.

Arthur smirked, leaning on the bar. “You’ve definitely pulled off hot date really well. The whole school was staring.” 

Merlin laughed, swirling his drink. “I guess having a handsome blonde next to me helps,” he said. “Though it’s weird being flirted with by my son, even if you are my date tonight.

Arthur grinned. “Think of it as bonding! Not every day I get to take my dad to prom. Gotta make it memorable!”

“Memorable, indeed,” Merlin said, unable to hide his smile. “It’s surreal to be here.. with you.” 

Memories of another prom, twenty years ago, flashed in Merlin's mind. He remembered Freya in her emerald dress, looking perfect with her dark hair pinned up. He’d fumbled with the corsage, both of them knowing he was under her spell. The memory made him feel bittersweet, but Arthur’s presence eased it.

Arthur nudged him, snapping him back to the present. “You okay, Dad?”

Merlin smiled. “Yeah, just a memory. Nothing big.”

Arthur grinned. “Hope I’m doing it justice.”

Merlin laughed. “You are. More than you know.” He sipped his drink, feeling both past and present mix together.

“Wait ‘til you see my dance moves,” Arthur said with a smirk. “You might end up wanting a second date.”

Merlin rolled his eyes playfully. “We'll see.”

“I'll prove it to you!” Arthur exclaimed mischievously as he again took Merlin’s hand and led him back to the dance floor.

As the last dance was announced, Arthur pulled Merlin in close for one last slow dance. He felt a pang of sadness at the lyrics: 

I'm standing where the lightning strikes, I know this doesn't happen twice. You must be my once in a lifetime, in a lifetime…

“Why can’t this just last forever?” he murmured softly into one of Merlin’s oversized ears. 

Merlin’s breath caught before he collected himself. “Nothing lasts forever, kiddo. You know this. But.. we still have the after-party at Morgana’s huge mansion, right?”

“Oh! Yes, of course!” Arthur exclaimed, eyes bright once more. Quickly, he pecked Merlin’s lips.

 

Morgana’s event room was buzzing with chaotic energy, bursting with roughly about 150 people. Gwaine and Lancelot debated whose dance moves were better, with Gwaine claiming winning Prom King was proof it was obviously him. Meanwhile, Gwen and Morgana set up a photo booth with props and colorful backdrops. 

Arthur felt a burst of excitement as he looked around. The dance had been a dream, and now it was time to let loose and enjoy the company of friends in a more intimate, familiar setting. He glanced at Merlin, who was chatting with Leon and Percy near the snack table. 

Even after all the dancing and chaotic energy of the prom and now the after-party, Merlin still looked effortlessly handsome. His dark hair was slightly mussed as he sported his usual easy smile. Arthur couldn’t help thinking how much like a classmate he looked. 

Merlin’s bright yellow tie was loosened and the top few buttons of his seafoam shirt were undone, revealing a hint of sharp collarbones. Dark curls could be seen poking out from his shirt. His sleeves were rolled up to the elbows and he looked so at ease, leaning back against the bar with that laid-back, mischievous smile that never failed to make Arthur’s heart race. 

Arthur swallowed, catching himself staring a moment too long. Merlin caught Arthur goggling and smirked. “What?” He took a sip of his punch. “You’re staring, kiddo.”  

Arthur’s face flushed, but he didn’t look away. “You look… good.”  

Merlin chuckled, glancing down at himself. “Well, I’d hope so—prom’s a big night.”  

Arthur’s gaze lingered. “Ridiculously hot,” he muttered as he took a pee break. Why was his dad so fucking hot?  

Merlin heard it, smiled to himself, and took another sip, resuming his conversation with Leon and Percy.  

As Arthur and his dad eventually moved through the after-party, he noticed the whispers and giggles directed at them. If only they knew Merlin was his dad.

Half an hour into the after-party, Merlin flopped next to Arthur, arm draped casually over the back of the couch. “What’s next, my little Prince Charming?” 

Arthur, cheeks flushed, glanced down at Merlin's lips, before grinning. "This," he said, suddenly jumping onto a table and grabbing the mic. "Alright party people! Who's up for a game?" 

The party exploded in whoops of excitement. 

Merlin chuckled, crossing his arms. "Show-off," he muttered.

“Count me in!” Morgana shouted, a large grin spreading across her face. “What’s the plan, Arthur? Never Have I Ever, Truth or Dare? Seven Minutes in Heaven?”

Gwaine smirked, leaning into the circle. “Or maybe Seven Minutes in Hell—where you lock two people in a closet, and they just beat the crap out of each other!”  

Elyan laughed. “Now that’s a game with some stakes!”  

Valiant, who’d looked bored, perked up. “Finally, someone speaking my language.”  

Percy grinned. “I’m down for whatever.”  

"No, absolutely not!" Gwen exclaimed. "What are we, barbarians?"

"Some of us," Cenred said.

Arthur smirked. “No, none of that. Don't want anyone getting sued for injuries." He glanced at the crowd, with disappointed groans coming from most of the guys. "How about ‘Truth or Dare’?”  

“Yes, let’s do it!” Morgana said, sitting next to Gwen and smirking at the group. “By the way,” she added, looking over with her usual witchy evil smirk. “I always pick dare.” 

“Looks like this could get intense. For those who need to lower their inhibitions,” Gwaine said with a cheeky grin as he whipped out a bong from seemingly thin air, “...who’s in?”

Morgana smirked. "Pass it over."

Mithian leaned towards her. “I get it after you!” 

Merlin rolled his eyes, but when the bong came his way, he took a hit. This wasn’t his first rodeo. 

Gwaine burst into laughter. "Legend!" he cried, pointing at Merlin.

Arthur’s jaw dropped. “Da-Merlin!

Merlin exhaled a slow cloud of smoke, looking completely unbothered. “What?”

Arthur gestured wildly. “You—you can’t just—”

Merlin raised an eyebrow. “Can’t what? Take a hit?”

Arthur’s eye twitched. “I—You—” He groaned, running his hands through his hair. “I’ve never seen you do that before!”

Merlin smirked. “Guess you don’t know everything about me.”

Arthur sputtered, “I—That’s—I’m filing a complaint!” before taking a hit himself.

After the bong got passed around, Gwaine turned to Morgana. “Truth or dare?”

She rolled her eyes. “Did the THC muddle your brain? What did I just say?”

He grinned. “I dare you to make an impression of Cedric.”

Immediately, she straightened up, mimicking Cedric’s posture to an alarmingly accurate degree. Lowering her voice, she squared her shoulders and leaned into Gwaine’s space. “Just here for the company. Maybe I’ll dance, but no promises.”

The group burst into laughter, even Cedric. Morgana had nailed it, from his hair toss to his faint smirk. “Well, well, Morgana, I didn’t know you watched me so closely,” he said with a sly wink.

She was laughing. "Oh, please, try not to flatter yourself too much." She grinned at Mithian. "Truth or dare?"

Mithian raised an eyebrow. “Dare.” 

Morgana smirked. “I dare you to kiss whoever you think is the cutest… guy or girl.”

Laughter ripped through the crowd as Mithian glanced around. She didn’t need to think long before making a beeline straight towards Lancelot, who, at present, had his arm slung around Gwen. 

“Excuse me, coming through,” she said, apologetically. 

Before Lancelot or Gwen could react, Mithian landed a kiss on Lancelot's cheek. “Sorry Gwen,” Mithian said sheepishly, at Gwen’s open-mouthed gape. 

The crowd went absolutely wild. “Oh please, it’s not like we frenched,” Mithian said, rolling her eyes good-naturedly. "Elena, truth or dare?"

Elena was grinning. "Dare."

"I dare you to sing your favorite song out loud, right here, right now," Mithian declared.

Elena groaned. "You’re the worst," she whined before standing up and belting out the first lines, cheeks flushing as everyone cheered.

As the game progressed, the energy in the room was electric as the level of extremity in dares continued getting wilder each turn. At last Gwaine leaned back, clearly plotting his next move. 

When the attention turned to him, he rubbed his hands together, hazel eyes gleaming. “Truth or dare,” he asked Arthur.

Arthur barely hesitated. “Dare,” he replied.

Gwaine’s grin widened as he leaned back, hands clasped, eyes twinkling with mischief. Everyone leaned in eagerly.  

“Alright, Arthur, I dare you…” He paused for effect. “…to kiss your date.” He pointed at Merlin.  

The room exploded with laughter and cheers. “Yeah, Arthur, your poor date’s been waiting all night!”  

“DO IT!” someone yelled.  

Arthur turned deep red, glancing at Merlin, who just smirked, shaking his head with a quiet laugh. His dad looked amused.

“Seriously, Gwaine?” Arthur groaned. Then he rolled his eyes and scoffed, and with all the bravado in the world, “I do that all the time.” 

Gwaine grinned, folding his arms with a glint of mischief in his eye. “Oh, we can tell,” he shot back, giving Arthur a pointed look. “But I mean a real kiss. None of that pecking stuff that Mithian did with Lance. Let’s see some fire!” 

The room filled with laughter, and Arthur could feel everyone’s eyes on him, waiting. All except his close-knit circle had no idea who Merlin really was. Merlin raised an eyebrow, his smirk widening. 

Arthur sighed, heart pounding. “Alright, alright!” he said, pretending to be annoyed. “If it’ll shut you up, Gwaine, then fine.”

He turned fully to his dad, voice dropping to a playful whisper, “Guess we’d better give them a show.” 

Merlin chuckled, but his cheeks were beginning to color now that he saw Arthur may actually go through with it. “Only if you’re up for it, kiddo,” he murmured softly, sending a thrill down Arthur’s spine at the sheer fact that his dad would actually let him kiss him. With tongue. 

“Absolutely! Don’t be a coward!” Gwaine jibed. “It’s just a kiss, mate! Show us how much you love your ‘date’!” 

The laughter in the room surged, and Arthur felt his heart race. The challenge hung in the air, and over his head. He exchanged a quick glance with his father, and Merlin’s crooked smile and usual awkward charm made him all the more endearing. 

His father had that usual dopey, lidded-eyes look that came with being high, but now he looked a tad shy. His cheeks were flushed from the bong and the combination somehow made him look even younger and infinitely more boyish. It was a look that Arthur always found irresistible.

Thinking about the dare, Arthur’s face flushed with thrill of a dare that actually posed a challenge. He was all about overcoming challenges, his father had taught him well.

How long have I wanted this? Really, truly wanted this? To feel Dad’s tongue in my mouth again… He kicked himself. Dreams were just dreams. This french kissing had never happened in real life, or ever!

“Fine, fine! I’ll show you!” Arthur declared, voice gaining confidence as he sat up straighter. 

“Get on with it!” someone shouted. The laughter and playful teasing continued, and Arthur could feel his cheeks heat further.

Biting his lip, he knew he was excited. He wanted to know how kissing his dad with tongue would feel in real life. Would it be just as it was in his dreams? 

Merlin raised a brow, smiling fondly. Part of him wanted to laugh at the absurdity of it all, but another secret part felt a surprising thrill at the idea that his son may actually go through with it. He knew Arthur had always been competitive, but all this over a party game? 

Leaning back on his palms, Merlin shot him a challenging look. “Well then, let’s see what you’ve got,” he smirked. 

Arthur’s dick jumped at the seemingly flirtatious attitude of his father. His breath hitched as he leaned in. “Just a quick one then,” he mumbled.

Merlin blushed. “You’re the one who chose dare, remember?”

The air buzzed with energy, hearts racing.

“Shut up, Merlin.” With a playful shove, Arthur closed the gap, hands on Merlin’s face, capturing his lips.

Arthur’s heart pounded. He’d dreamt of this—soft, lingering, familiar. Those dreams left him waking up with a strange longing. Now, in the heat of the moment, they felt like a memory guiding him.

He leaned in, lips parting, tongue brushing against Merlin’s. Merlin kissed back, like he somehow already knew how—like rediscovering something that had been lost, and the room faded. Nothing else mattered. Their lips moved in sync, as if they’d done this a thousand times.

I’ve missed this, Arthur thought—then realized it was their first time. He must be losing it. With this startling realization, Arthur abruptly pulled away. His dad’s fevered face shifted instantly from surprise to.. was that disappointment?

Both he and his father were breathless and flushed, immediately moving to attempt to discreetly cover their arousals. Merlin’s eyes were wide, looking utterly flustered. The tips of his large ears had turned a deep shade of red, and Arthur couldn’t help but feel a rush of warmth at how endearing his dad looked. It made him want to kiss him all over again. 

He glanced around to see his friends wide-eyed, stunned and whistling. “Holy shit,” Gwaine exclaimed. “That make-out session was… Didn’t expect you two to go all in like that!” 

“You sure that was your first time?” Lancelot joked, laughing nervously.

“You’ve always been joined at the hip, but didn’t see that one coming!” Elyan remarked, scratching his head. 

Gwen, having collected herself, grinned, nudging Morgana, who had one eyebrow raised, clearly as intrigued as she was surprised. “Guess Arthur really wanted to make a point!” Gwen said.

Arthur nervously met Merlin’s gaze, and Merlin’s own cheeks were flushed. He gave Arthur a slightly bashful smile that made Arthur’s stomach flip.

Smirking and trying to hide just how flustered he felt, Arthur said, “Oh, come on, you lot. It was just a kiss.” 

But Morgana wasn’t letting him off that easily. “Just a kiss?” she repeated, her voice dripping with suspicion. “Arthur, that was practically cinematic. You two weren’t holding back. You must’ve been kissing for an entire minute!”

“Yeah, I timed it,” quipped Mordred, holding up his stopwatch. “One minute and eight seconds, to be exact.”

Arthur's cheeks flushed deeper, and he shot them all a defensive glare. "Then why didn’t anyone stop us?" 

Gwaine leaned back, grinning. "Stop you? Are you kidding? We were all enjoying the show!"

"Was going to ask if you two wanted to get a room," Elena said, giggling. "But it didn't feel right breaking that up."

Arthur groaned as Merlin pinched his nose. Both were mortified.

Their kiss remained on the father-son duo’s mind all night. It still felt surreal, like it didn’t actually happen. Yet, it all felt achingly familiar, more like a homecoming than a newfound revelation. They were both so fucked.

 

When they at last walked into their bedroom, the clock read 3:13 AM and both were exhausted. “Maybe we should’ve just slept over at Morgana’s,” Arthur complained. 

“And risk Uther Pendragon’s morning-after wrath?” Merlin asked, gasping in mock horror. 

Arthur laughed, yawning. “No, I guess not.”

Arthur turned on the lights. “Shower in the morning then?” 

Merlin grunted in assent, already changing into his cartoon dragon shirt and shorts. “Ready for bed?” Merlin asked. 

“Yeah,” he replied, eyes lingering on his dad’s fit frame as he too, changed. 

As they both climbed into bed, Arthur made room for his father, and their bodies pressed in close, their heartbeats immediately synchronizing. 

They exchanged smiles, and Arthur at last asked, “Do you think..” He looked away. “Do you think it’s weird that we still sleep in the same bed?”

Merlin glanced at him in surprise. “Does it make you uncomfortable? Because if it does–”

“No!” Arthur blurted. “No, I–I love it, actually. Makes me feel safe.”

Merlin’s eyes softened. “Okay. Then if it makes you feel safe, then I’m glad.”

Chapter Text

By the time Arthur was finally 18 and of legal drinking age, he was inviting Merlin to all his university frat parties. No one blinked an eye. Everyone automatically assumed Merlin was a student and Arthur’s boyfriend.

Arthur and Merlin pushed through the crowded frat party, hands clasped. Cheers and greetings followed them, and Merlin chuckled at the usual chaotic energy.

“Arthur! Merlin!” Gwaine called, raising a red plastic cup in their direction. He was grinning wide, already well into his drinks for the night. “Look who finally showed up! Thought you two were gonna ditch us and run off together again.” His brows waggled suggestively.

Arthur rolled his eyes, winking. “Don’t worry Gwaine, we wouldn’t dream of leaving you alone.” 

Morgana nudged Gwaine with a knowing smile, glancing pointedly at Merlin. “Of course they didn’t ditch us. Merlin wouldn’t let his ‘boyfriend’ miss a good party.” She said "boyfriend" with a teasing drawl, making Merlin chuckle.

Gwen smiled from the corner with Lancelot. “You two are adorable. Half the campus is convinced you’re dating, you know.”

Lancelot nodded. “With how you two are always together—kissing in the halls, holding hands—it’s pretty obvious,” he said with a smirk.

Arthur flushed but didn’t deny it. He didn’t mind everyone thinking they were together. Discreetly, he gave a sideways glance down at Merlin. Merlin was only smiling with a pink flush on his high cheekbones.

Mordred raised an eyebrow with a playful smirk. “I’m just surprised Merlin even goes to these things. Thought you were more of a ‘stay home with tea and books’ kind of guy.” 

Merlin laughed. “I can’t leave Arthur alone at these parties, can I? Someone has to keep an eye on him.” Merlin ruffled Arthur’s hair affectionately. 

Percy chimed in, “The way you two stick together, it’s no wonder everyone just assumes you’re a couple. I can’t even imagine my dad at these things.” 

Leon laughed, clapping Arthur on the back. “Not to mention, you’re like a package deal at this point. Since Arthur’s started university, I don’t think I’ve ever seen you two apart.”

"Perks of remote work," Merlin said with a wide grin, work laptop under an arm. 

As the night wore on, laughter and music filled the room, but Merlin never left Arthur’s side, draping an arm over his shoulder and keeping him close the whole night. Drinks kept getting shoved at everyone at the party, one after another. Merlin and Arthur downed them all one by one, giggling like schoolboys, feeling bolder, tipsier, warmer. As Arthur looked at Merlin, he felt the same familiar, raw, and electric feelings that he constantly felt in his dreams. 

Before he knew it, they stumbled into a quiet hallway, and Merlin gave him a lopsided grin, pulling Arthur into a small bathroom. The door clicked shut, muffling the party noise. It was just them. Arthur’s heart raced as their eyes met.  

Without thinking, he leaned in, pressing his lips against Merlin’s, just as they usually did. What usually continued softly quickly devolved into a sloppy mess, the stench of alcohol heavy on their breaths as they licked and sucked at one another. As Arthur let out moans, his cock strained hard and leaking in his trousers.

“Shii–!” Arthur hissed.

Merlin’s hands were everywhere, tangled in his son's hair, sliding along his back, his hips, as they grind their hard bulges together, gasping. Merlin was pinned against the wall, Arthur’s body pressing into him. Their breaths mixed, heavy and desperate. Arthur’s fingers tugged at Merlin’s hair as their hips rocked together, pulling soft moans from him.

"Arthur–," Merlin gasped against Arthur's mouth, hands gripping his hoodie. Arthur kissed Merlin deeper, his hand gripping Merlin's hip to guide their movements. The friction built as they rocked together, lost in it. 

When they broke for air, Arthur, forehead pressed to Merlin’s, moaned, “You’re all mine, Dad,” as he nipped Merlin’s lower lip. Merlin could only nod dumbly in response, too overwhelmed by Arthur's heat and the way their hips moved together. He was so hard, about to lose it.

They stumbled down the hall, giggling and stealing kisses, until they almost ran into Gwaine, who was holding a messy-looking Morgana. Gwaine, bleary-eyed but still charming, grinned at them.

“Well, well, look who’s having a good night,” Gwaine slurred, his arm wrapped around Morgana, whose lipstick was smeared all over Gwaine’s cheek and neck. “Didn’t know you two were… busy.”

Arthur just laughed, his arm tightening around Merlin’s waist. “Speak for yourself,” he teased, nodding toward Morgana with a smirk.

Gwaine raised his drink in a clumsy salute. "Aren't we all living our best lives?" Gwaine mumbled before kissing Morgana again. 

Merlin laughed, but it faded as Arthur pulled him closer, their bodies swaying as they walked. 

When they reached a vacant bedroom, they collapsed onto the bed, tangled up in drunken laughter. Tired and dizzy, they soon passed out.

The next morning, they woke up with monster hangovers, draped over each other with no memory of the night before. Looking at the mess around them, it had clearly been a wild party.

 

They continued partying together, week after week. Arthur would wrap up a week of hard work and studies, top marks in every subject, and Merlin would close out his own demanding projects, always meeting his deadlines. Friday evenings were theirs. 

They’d arrive at a friend’s house or party venue together. Merlin would gravitate towards the music, his easy laugh carrying over the crowd, and Arthur, always nearby, would watch him with a warm grin, somehow feeling lighter just from Merlin’s presence.

After a few drinks, they grew bolder. They sat close, laughing and joking. Arthur’s hand rested on Merlin’s knee, tapping to the music. Merlin had never pulled away before, and he didn’t start now, instead leaning in until they were pressed side by side, practically in each other's laps.

The music soon pulled them to the dance floor. They swayed together, hips brushing, lost in the rhythm. Arthur leaned in, grinning. "Pretty sure we're the best dancers here."

“Is that so?” Merlin grinned back, pulling Arthur closer. “I’d say we’re the only ones brave enough to dance this terribly.”

Arthur chuckled, rolling his eyes. “Hey, I’ll have you know this is skill. Pure, unrefined talent.” He spun Merlin around, their faces inches apart as they reconnected in the next step.

“Oh yeah?” Merlin smirked, raising a brow. “Well, in that case…” He leaned in, voice softening to a whisper. "Show me what you've got, Mr. Perfect."

Arthur laughed, his face heating up but meeting Merlin’s challenge. He moved a little closer, dancing together, just a bit too near, a bit too long.

With a grin, Arthur warned, "Careful Dad, keep this up and I'll be dancing with you all night."

"Would that be bad?" Merlin asked, eyes glowing. 

“Not even a little,” Arthur replied, voice low and sultry as they moved together, perfectly in sync, like no one else mattered.

It always ended the same: tangled together in a quiet hallway or pressed against a wall. Merlin's hands would grip Arthur’s back. “You know we shouldn’t be doing this here, right?”

Arthur would smirked, his voice a whisper in Merlin's ear, “Since when did that stop us?” He leaned in, kissing Merlin with hungry intensity. “Love you, Dad.”

Their kisses deepened, Merlin’s hands gripping Arthur’s waist and pulling him close. Arthur groaned, head tipping back. “God, Dad… you mess me up.” 

Merlin grinned, breathless. “Good. Stop thinking.”

Their hands roamed, tugging at shirts and belt loops, pulling soft gasps from each other. Arthur’s hand tangled in Merlin’s hair, while Merlin’s hands gripped his sides, holding him close.

When it got almost too much, Merlin would pull back, eyes dark, and grin. “Think this’ll keep happening?”

Arthur caught his breath, grinning back. “At this rate? Yeah. I'm not stopping anytime soon."

The first time it happened, Merlin knelt, looking up at Arthur, whose face was a mix of excitement and nerves.

Merlin’s fingers ran along Arthur’s waistband, hearing his sharp breath. The tension between them buzzed, every sound and touch amplified.

Merlin hurriedly undid Arthur’s jeans, hands shaking with anticipation. As he wrapped his fingers around his shaft, Arthur’s hands clenched at his sides, eyes wide in disbelief. The moment Merlin’s tongue touched him, a dizzyingly familiar feeling exploded behind both their eyes. 

Merlin immediately knew the perfect way Arthur liked it, and in within just a few moments, the intensity of it quickly built to a crescendo as Arthur warned, “Dad–! I think I’m gonna—!”

Merlin only kept sucking, humming with pleasure, palming himself. 

“Dad–fuck!” he cried, fingers gripping Merlin’s hair, before releasing all of himself into his father's mouth.  

They kissed hard, breaths mixing. Tasting himself on Merlin’s tongue made Arthur laugh softly, flushed and pressed close. When they finally pulled apart, panting, foreheads touching, Arthur smiled. “Maybe… we should keep doing this.”

Merlin grinned, thumb brushing Arthur’s jaw. “Maybe,” he whispered, stealing another kiss. 

By night’s end, they stumbled home together, collapsing into bed side by side.

The following morning, they both awoke with splitting hangovers and neither remembered a thing. 

 

This became a regular non-regular habit of theirs. They both quickly relearned how to pleasure one another just as well as they had during their last lifetime together.

At times Arthur would fuck Merlin up against a door, biting his neck as he spilled his warm seed inside, or they would do the dirty on the floor, or in some university kid’s bed. Everyone was fucking at every turn at the parties, so when they were inadvertently walked in on once or twice, no one batted an eye. 

As they stepped into the dimly lit room, Gwaine, Leon, and Will were greeted with the sight of a very drunk Merlin and 21-year-old Arthur tangled up on the bed, tongue in each other’s mouths, bodies pressed together in a way that left little to the imagination. 

Gwaine leaned against the doorframe, grinning. "Well, well, what do we have here? Not even two hours in, and you two are already getting cozy," he drawled, barely holding back a laugh.

He knew this father-son incest shit was totally weird, but since Arthur started university, Gwaine had begun suspecting there was more going on. And well, if it made his best friend happy, then who was he to oppose two consenting adults showing love for one another?

Merlin and Arthur barely broke their rhythm, but Arthur, ever the show-off, managed to pull his lips away from Merlin’s for a moment, grin wide and drunken.

“What can I say? We’re just that efficient,” he slurred, before leaning in to kiss Merlin again.

Leon chuckled. He too, had accepted his best friend’s choice in lovers, no matter how taboo it was. "Honestly, are we even surprised?" he asked. 

Will, still unaware the two were related, only rolled his eyes. “There’s a lock. Use it.”

Gwaine laughed, clapping Will on the shoulder. "Oh, mate, this is probably tame for them."

Will shrugged. "Alright then… I guess I'm grabbing a drink!" he said, grinning as he backed out of the room. 

“Good call,” Gwaine agreed, winking. “Let’s leave these two to… bonding.

Leon pulled the door closed with a smirk, and the three of them headed back into the party.

 

Merlin winced at his phone—7:03 p.m. Arthur’s text echoed in his mind: 5 p.m. sharp, don’t be late! Merlin sighed, rubbing his temple as he imagined Arthur’s disappointment. He refocused on the meeting.  

“Sorry, but since we're just wrapping up now,” he said, glancing around. “I’ve gotta dip out a few minutes early, if that's okay.”  

Annis raised an eyebrow. “Not like you to leave early, Merlin.”  

Gaius, across from him, gave a wry smile. “The youth in his life must have something pressing for him. Arthur, I assume?”

Merlin chuckled, glancing sheepishly at his phone again. “Yes, well… I promised I’d be there. Tonight’s special.”

Annis’s eyebrow stayed raised. “Oh? What's special about tonight?"

Merlin smiled, looking at his phone. "Arthur just won the rugby championships. They’ve worked hard, and tonight, they’re celebrating. I promised I'd be there."

Gaius nodded, expression fond. “Quite the accomplishment. And I suppose he’s got the whole uni buzzing?”

Merlin laughed. “You could say that. He’s the star player—it’s a big deal for him, for the whole team. They've been working for this all year."  

Annis softened and smiled. “Well, then. Who are we to stand between a father and his son’s victory celebration?”

Merlin nodded gratefully, already reaching for his things. “Thanks, everyone. I’ll see you at the next meeting.”

“Just make sure you don't drink too much. Hangovers are nasty things,” Gaius warned, a twinkle in his eye. 

“Don't I know it,” Merlin said, chuckling. 

As he hopped on his electric bicycle, Merlin felt a twinge of guilt for arriving so late. Arthur had waited two hours. Merlin could only hope he hadn’t ruined Arthur’s night by being so wrapped up in the protest planning.

As he finally cycled up on his bright blue electric bike, he looked every bit the part of the colorful activist he was, with his vibrant yellow nerd glasses and a tote bag covered in pins declaring everything from “Save the Bees” to “Ban Plastic.”

He tried cleaning up in the club’s tiny bathroom, tugging at his messy hair and wiping smudges of vegan queso sauce from his shirt before stepping out.

Arthur, drunk, spotted Merlin and stumbled over. He kissed Merlin sloppily, pressing his tongue at his lips, but Merlin pulled back, holding him off. "Whoa, Arthur!" he laughed nervously, trying to read his son’s eyes. "It’s me, your father."

Arthur blinked, looking genuinely confused but far too gone to piece together Merlin's reaction. He leaned in, swaying, with a lazy smile. "C’mon, Dad," he murmured, his breath heavy with alcohol. "It's just a kiss."

Merlin laughed softly. "Not usually this kind of kiss, Arthur," he teased, gently steering Arthur into a seat. 

Arthur slumped down but kept one hand on Merlin’s arm, pulling him closer. "You never mind," he said, voice a low mumble. “You never mind… anything.”

Merlin's smile faltered as he thought back on those nights when they’d both woken up, hungover and nursing suspicious bruises, hickeys, and sore bottoms. He’d always laughed it off, assuming they’d both gotten a bit frisky with some university students in their drunken states.

Merlin knew he still passed as Arthur’s age… Oftentimes other students catcalled him when he walked by, even if he was with Arthur. But the idea that he might've somehow gotten sexually involved with his own son never crossed his mind, and even now he refused to entertain the notion.

Clearing his throat, Merlin ruffled Arthur’s hair. “Alright, big guy, maybe we should get you home.” He managed a smile, prying a drink from Arthur’s hand. “And set this down.”

Arthur’s eyes lit up, smirking mischievously. He leaned in, face just inches from Merlin’s, voice low and highly suggestive. “Oh, so that’s what you want? Bathroom isn’t private enough?”

Merlin’s cheeks flushed as he tried to backtrack, realizing the very wrong way Arthur had interpreted his words. “Arthur, that’s not—I mean, I just think you need a little sleep and some rest, kiddo.” 

At this time, Lancelot, with an arm around a giggling too-far-gone Gwen, stepped in. “Arthur, your dad just wants to take you home now, okay? You’ve had enough."  

Arthur blinked, surprised (though he shouldn't have been--Lancelot was his teammate!) 

"Lancelot? What are you doing here?" he slurred, leaning on Merlin. "And he’s not my dad," he added, smiling at Merlin. “He’s… Merlin, and I’m not supposed to say anything but….” Arthur whispered conspiratorially, “he’s a wizard.”

Lancelot chuckled, steadying Gwen. “Whatever you say, mate. But Merlin’s right. Let him get you home before you do something you regret in the morning.”

Arthur leaned his head on Merlin’s shoulder, mumbling, “Don’t regret anything.” He looked up at Merlin, eyes glassy but earnest. “Not a thing.” 

Merlin’s heart skipped as he patted Arthur’s back. “I know,” he said gently. “But I’m still getting you home safe.”

Arthur grinned sleepily, clearly pleased. “Fine, Dad… but only if you promise to stay with me,” he said, wrapping his arms around Merlin’s waist, slurring as he said, “Like you always do.”

Lancelot gave Merlin a knowing look as they helped Arthur to his feet. “Come on, big guy. Let's get you some fresh air," Merlin said, gently guiding his son to the doorway.

Once there, Arthur leaned on Merlin’s shoulder, mumbling, "I don't know what I'd do without you, Dad."  

Merlin smiled, warmth blooming in his chest. “I’m not going anywhere, Arthur. Promise.”

At home, Merlin helped Arthur down the hall to their bedroom, supporting him as Arthur mumbled about how Merlin was "the best" and "too good" to him.

When they reached the bed, Merlin helped Arthur sit down and started taking off his jacket. "Alright, let's get you comfy," Merlin said, keeping it light. Arthur whined, swatting Merlin's hands away as he struggled with his shirt buttons.

“Don’t need… pajamas,” Arthur slurred, smirking lazily. “Boxers… are good enough.”

Merlin sighed. "Fine," he relented, removing Arthur's shirt. As he reached down to undo his son's belt, Arthur caught his wrists, eyes still half-lidded but suddenly seemingly more alert. 

"You too, Dad," he grinned slyly. "If I have to.. then, so do you."

A flush crept up Merlin's cheeks. "Arthur, that's not—"

"C'mon, Dad," Arthur hiccupped, leaning on him and grinning with half-closed eyes. "Just... be comfortable with me, yeah?" He tugged on Merlin's sleeve, his face getting closer, eyes wide and sincere.

“I did take my team to nationals, after all…” he added, trying to look coy but ending up just shy of pouting, his lip jutting out slightly.

Merlin stifled a laugh."Oh, you think that earns you special treatment?"

Arthur grinned, resting his head on Merlin’s shoulder. “Mmhmm. Big deal… team… nationals...” he mumbled, but his blue eyes stayed on Merlin.

Merlin sighed, finally relenting. “Alright, alright.” He tried to ignore the flutter in his chest as he removed his own clothing one by one, til he was just in his boxers. "Cold," he muttered as he climbed in bed with a delighted Arthur who immediately snuggled into him for warmth. 

"Even though you're skinny, you're still always so warm," Arthur yawned as he got into Merlin's space. "Promise.. that you'll stay." 

Merlin chuckled, kissing the top of his son's head. "Of course, Arthur. I am never leaving you, never. Just… get some sleep, love.”

Arthur let out a small, sleepy smile, nuzzling against Merlin. “Good… ’cause you’re all I want.”

 

One night, Merlin and 24-year-old Arthur slipped away from a crowded party, stumbling home together, laughing and occasionally puking in the gutter. It was all a blur, but their bodies knew where to go and what they needed.

At home, everything faded. The door shut, and without speaking, they quickly undressed, eager to feel each other’s skin. Clothes scattered as they reached the bed, free to be themselves.

Arthur's gaze turned predatory as he shoved Merlin flat on his back, hands gripping Merlin's thighs as he positioned himself at his father's hole. Merlin whimpered, voice barely a whisper. “Arthur… please.” His wet eyes were wide, pupils blown, body completely at Arthur’s mercy.

"Anything you want, love," Arthur whispered, then kissed Merlin deeply. Grinning, eyes unfocused, Arthur complied, spitting on his dick, spreading his saliva liberally, before he sank in bareback, giving tiny thrusts inside Merlin. Merlin gasped loudly on the first thrust, his back arched as pretty moans flew from his lips, which Arthur quickly claimed. 

Arthur soon left his mouth and trailed teeth and tongue all along Merlin's lithe body, leaving hickeys in his wake. "Gods, Arthur-" Merlin was moaning as Arthur set a punishing pace, lost in the heat of his father's pretty hole, sucking his cock greedily. But he wanted to give Merlin more, all of him. He gripped Merlin's hair and tugged him into another deep kiss. 

“More, more Arthur..” Merlin locked him in with his legs. Arthur held Merlin’s wrists on either side of his head and kept thrusting, lost in the pleasure of being so deep inside, buried to the hilt inside his Merlin. 

Even in his drunken state, Arthur angled his hips and hit Merlin’s prostate again and again as Merlin writhed in pleasure and screamed at the skies. Their bodies moved with a frantic urgency, desperate to be close in a way that they could only allow themselves when completely plastered. There was something intoxicating about being together—it was raw, messy, but real. 

When they finally came with shouts and moans, Merlin wrapped tired but tender arms around his son, cooing to him. They wrapped themselves around each other. “This is better,” Merlin murmured, his voice heavy with sleep. He curled into Arthur’s neck, listening to his steady heartbeat. In that moment, everything else felt far away.

 This—Arthur—was home.

Arthur pulled him closer, still half-drunk but content. “Yeah,” he whispered, fingers absently tracing patterns on Merlin’s back. “This is… everything.” 

And it was. 

 

The next morning, they woke tangled together, a rush of cold terror hitting them both at once. They rushed apart quickly, as if the distance could somehow erase what they’d done.

“What the fu– what did we do?!” Arthur exclaimed. His heart pounded rapidly and his thoughts spun out of control. 

Merlin, eyes wide with panic and the sheer terror of the situation, was muttering, “No no no… Shit, this... this can’t—it shouldn’t have happened.” But you should’ve realized, you moronic fuck. Merlin’s stomach was churning. 

Merlin thought back to last year, when a very drunk Arthur was trying to make out with him, as if it were the most normal thing in the whole world. The sudden realization that they were doing this shit in public hit him like a freight train. Fuck. FUCK.

He recalled all the times where he’d clearly had something up his arse all night, the burning sensation he’d chalked up to fooling around with some random college blokes. Of course it’d been his own kid’s dick. 

Looking up at Arthur, whose face appeared equally traumatized, he whispered, “We can’t do this again—get drunk together. Who knows what we’re like in public? At school? We—people can’t find out, Arthur. If they do, everything—everything will change. If we continue, this could ruin everything. And I can’t risk that for you. Not for this.” 

At the panicked expression in his son’s eyes, Merlin moved to touch Arthur’s trembling form reassuringly. “This won’t change how we are together—our relationship. I love you, and I always will. Nothing we’ve done can change that, or take away how much I love you.” 

Merlin continued resolutely, even as his voice shook. “W-we just won’t party together anymore, no more getting drunk with one another, everything else will stay the same.” We’ll still sleep in the same bed. That will never change. It can’t.

“I’m your father, not your friend. I should never have partied with you to begin with. I lost my way.” He began to tear up and wiped away a tear. “Freya… your mother trusted me to take care of you, to be the father you deserved. And instead, I’ve gone and… God, what would she even think of me?”

Arthur's heart twisted, hearing Merlin's pain laid bare like that. He reached out, gripping Merlin’s arm firmly, voice urgent. “Don’t say that. Don’t you dare talk like that,” he said, eyes burning fiercely with blue flames as he searched Merlin’s face. “You haven’t ruined anything, and you haven’t failed me. I know this… this isn’t what we planned, but it’s not all on you.”

Merlin shook his head, starting to pull away, but Arthur held tighter. “Look, maybe none of this is perfect, but… but I don’t care. You’ve always been there for me. You’ve been more than I could’ve ever hoped for, alright?”

His grip softened, and his tone became almost pleading. “So don’t punish yourself for this. We’ll figure it out together. I may no longer be the kid dying from cancer, but I still need you, Dad.. more than you know.” Arthur’s face crumpled, before continuing, “Just to be clear, Dad, you’re not… you’re not some mistake or risk I want to hide. I’m not a kid anymore—I know what I want. And I know.. I know I want you. All I want is you.” 

Arthur leaned forward, brushing a soft, lingering kiss on Merlin’s lips. His hand slid down Merlin’s trembling arm and his voice cracked as he spoke. “I’ve always loved you most.” Arthur paused, his voice soft. “I really don’t care what happens to me.”

But Merlin shook his head vehemently, pulling away. “You should care, Arthur. I care, and that’s why I can’t… I can’t do this to you. We have to stop. If people find out about this, it will impact your entire career. You won’t be able to land a good job after uni, and as your father, I.. I can’t have that on my conscience.”

After a long moment, Arthur at last nodded, wiping his eyes. He hadn’t even realized he’d begun crying. “Yeah, I understand.” With wobbly lips, he rasped, “Just to be clear, this only means no more drunken hangouts, right?” 

The worried look in his son’s eyes made Merlin’s heart clench painfully. He wiped a stray tear from his son’s eyes, wanting to soothe, to make sure Arthur knew that this mistake could never take away how much he loved him. Reaching over, Merlin tugged Arthur in and gently moved their lips together, breathing his son’s sweet natural scent in. “Yeah, nothing else has to change.”

 

As the seasons passed them by, Merlin and Arthur settled into a quieter routine. They kept to their old ways of being close—sharing meals, late-night talks, and moments of quiet affection. But the chaotic drunken hangouts were gone. They’d made a pact to never again let the intoxication of alcohol blur the boundaries they should’ve never crossed.

There were nights when they found themselves once again wrapped in each other’s warmth, not out of wild desperation, but because it was simply right. They didn’t need drunken nights to feel close—their love had always been there, since their atoms were first formed in the ether, a love that was steady as the stars in the sky.

One such night, feeling himself half-hard whilst cuddling, a 31-year-old Arthur murmured, “Dad, I.. I think we’ve known each other before.”

Merlin’s breath caught. “Your childhood dreams,” he said, already knowing what Arthur was referencing. 

“Every dream feels so real, like I’m remembering parts of my past—of us.” Arthur looked into Merlin’s eyes. “And when we had our first tongue kiss—you can’t tell me it didn't feel.. iono, familiar?”

Ygraine’s cryptic words echoed in his mind: ‘You and your son’s love is one of legend—continuously recycling throughout the ages.’

Merlin suddenly felt foolish, or as if he’d unintentionally gaslit his son about what they truly were to one another. “You think… your dreams are memories? Of past lives?” 

Arthur nodded. “I still have them nightly. They are so often.. explicit.” He bit his lip and looked at his father. "It feels like we’ve always been this way, like we were meant to be."

Merlin's eyes softened, and a smile spread across his face, filling Arthur's heart with warmth.

“I’ve felt it too, Arthur,” he admitted quietly. “And there’s something I should’ve told you a long time ago..” 

Merlin at last shared with Arthur everything about Ygraine and her visitation. “At first I wasn’t sure.. But then you got better, just as Ygraine promised.” 

After he finished, Arthur stared, stunned. The words felt too big to grasp, but as he looked into Merlin’s eyes, he felt their truth fill him, a brilliant light filling the empty spaces inside him.

“So… we’ve really been doing this… loving each other… forever?” Arthur’s hoarse voice was barely above a whisper, and his hands shook as he took Merlin’s, grounding himself in the warmth of his touch. 

Merlin nodded, his eyes shining with quiet joy. “Yes. In every life, in every time across space, we find each other. We’re… inevitable.” He chuckled softly, but his voice was thick with emotion. 

Arthur moved to hold Merlin in his arms. “Then let’s just be together, Dad, and fuck the world. We’ve been waiting thousands of years now if my dreams and Ygraine are anything to go on. We died eternal lovers. We shouldn’t abandon our past when it keeps making itself known in the present.. That has to be for a reason, right? I don’t think our past selves would’ve wanted to be separated like this.

Yeah, it’s unfortunate that we reincarnated as father and son, but what we feel surpasses that taboo, doesn’t it? We were lovers first. Father-son second. We can be secret lovers, or even move somewhere where no one knows who we are. Start over. Please…”

“Arthur,” Merlin murmured, voice barely a breath. 

He knew they were teetering on a precipice, standing at the edge of something irreversible. If they jumped, there would be no going back. But when Arthur looked at him like that—like he was the only thing in the world that mattered—Merlin wasn’t sure he wanted to go back at all.

 “You have no idea how much I want that. To just… live. Finally just be… us.”

Arthur hugged him tighter, his face in Merlin’s shoulder. “Then let’s do it. We’ve waited a thousand years—don’t we finally deserve to be truly happy together?”

Merlin’s smile grew, bright and real. He felt something inside him release, like a chain breaking. “Why not?”

Arthur grinned, pressing a kiss to his father’s forehead. “Love you to the moon and back,” he promised.

Merlin never forgot that other Merlin who had given him and his son a life full of joy. Sometimes, he quietly prayed in thanks. Because of him, their life was full of peace, love, and endless abundance.
