Throughout his life, Yeon had done nothing but cause pain to his beloved dongsaeng. Hurting Sarang had never been his intention, but it was his reality. There were no actions he could possibly take to make it up to her. Some wrongs were too impossible to make right. But it wouldn’t stop him from trying. She was all he had left. The only family he’d ever truly known.
Yeon had now lost his love in turn. Centuries later, discovering her reincarnation had meant nothing, for she held no interest in him. It was only natural, for she wasn’t that same woman from all those years ago. Even then, Yeon wondered if he’d ever truly loved either of them to begin with. In truth, Yeon’s first love had emerged before that. Long before. Another person, a special someone who was very dear to him, and who knew Yeon better than anyone else. Those feelings scared him, to the point where he’d turned her away, hurt her, abandoned his divinity, and run from home as it burnt to dust.
Yeon had used Aheum as an excuse, a distraction, for his growing feelings. Those feelings which he deemed unnatural, too dangerous to allow them to be known. Now that he’d found himself alone once more, all Yeon had left was Sarang; his family, his dongsaeng, and most of all— the one his heart desired most.
Their reunion did not go to plan.
Sarang was yelling at him. There was undeniable hurt in her voice, passion drawing from the hell she’d endured in his absence, all because of him. Yeon stood there with an unreadable expression. Everything she said was true. Yeon had failed her in every way. He couldn’t even protect her when she needed him the most. This was what he deserved: nothing but her hatred of him. Yeon’s heart continued to yearn for her regardless, breaking further in two.
She was running out of steam. Insults began to fade out. She was shivering, sobbing through broken breaths. Yeon didn’t take his eyes off her. He reached out, drawing her in close. Sarang fought back against him, swearing and hitting his chest. But Yeon persisted. Soon, he was holding her flush against his body, rubbing her back in a calm, gentle, soothing motion.
Gradually, Sarang calmed down. Harsh words dissipated. Sobs quieted down. Tears dampened his shirt.
“I’m sorry, Rang-ah,” Yeon said softly, resting a hand to her lower back. “I never meant to abandon you, or hurt you.”
“But you did. You did, oppa. What did I ever do, to...” Her breath hitched. Speaking was growing all the more difficult. “I loved you. And you— you left me to die.”
“Rang-ah, I’m sorry. I didn’t mean to push you away, or hurt you, I...” Yeon tensed, pulling them apart to see her expression. “I was afraid, I— I love you. I love you so much, my dongsaeng... More than you can ever imagine.”
Yeon was staring into her eyes. So close, so intimate, so impossibly stunning before him. His love could be interpreted in many ways, especially when it came to his dongsaeng. This was a moment of truth, a boundary he had to overstep; risking it all to follow his heart. Closing the distance between them, he caught her lips with his own. The kiss was soft, brief. A lifetime of longing flowing free after centuries of unrest.
Yeon had become far too caught up in the moment. He pulled back, glancing away with embarrassment. “I’m sorry, I shouldn’t have done that.” He placed a hand over his mouth. “This is why I—” He stopped himself. He wasn’t sure if he could bare the response to a confession. He didn’t want to lose her.
Sarang stared at him in shock, full of questions. She wouldn’t let him go, tugging on his shirt. “Oppa. Tell me.” She swallowed thickly, a deep blush spreading across her cheeks. “Is this why you pushed me away all these years?”
Yeon couldn’t bare to look at her, struggling to speak through his shame. “I could never force my feelings upon you, Rang-ah,” he confessed, on the verge of breaking down completely. “I didn’t know what to do.”
“You could have asked. You couldn’t have told me. You never even asked my how I felt,” Sarang said sternly. “Oppa... look at me.”
Yeon finally met her eyes, torn by his conflicting feelings. “You’re my dongsaeng. I shouldn’t—”
“I don’t care. Why does it matter?” Sarang was struggling to get through to him, knowing how thick-headed her brother could be sometimes. So she pulled him back into a warm embrace, nuzzling into his chest. “Please... stay here with me...”
“Rang-ah...” Yeon hugged her tight, holding her as close as possible, resting a hand to her head. “I’m not going anywhere.”
Yeon awoke slowly, unable to remember where he was for a moment. He was lying on something soft, a warm body pressed beside his own. The room was unfamiliar at first, before memories began creeping back in to his subconscious. He was not in his apartment for once. This was his dongsaeng’s home; a small apartment on the other side of the city. And most importantly; she was the one currently snuggled in his warm embrace.
After their fight, he’d held her closely in his arms. They had both become exhausted, talking endlessly into the night. Feelings were made clear. Emotions were let out. And their relationship, somehow, had begun to mend. Yeon still believed he didn’t deserve it— not the forgiveness, nor her love. But he couldn’t deny how much he craved it, especially the latter. His desires had grown restless, wanting more, yearning for his dongsaeng in every conceivable way.
Even now as Yeon woke, Sarang remained asleep. Her chest rose and fell at an even, calm rhythm. There were dark marks around her eyes from tears, and her hair had become a mess. Regardless of that, she was so beautiful like this, almost peaceful in her slumber. Yeon smiled, a hand resting lazily on her hip. Their bodies matched; fitting perfectly beside one another. She felt so small against him, both in height and build. Almost frail in a way, but a fighter nonetheless. Sarang was far more dangerous and capable of holding her own than one would assume from her initial appearance.
So many years had passed between them, and Sarang’s beauty remained, beyond what words could describe. Stunning is what Yeon would say, but his dongsaeng always tried to hide her beauty, never wishing to capture another’s gaze. In hindsight, that was something he was thankful for, if not for giving him the time he needed to sort out his complicated feelings, before she had a chance to disappear into another’s arms.
In all honesty, Yeon was angered at himself for not realising sooner, for not accepting himself and his feelings, and coming clean to Sarang the way she deserved. There were so many years they could have already spent together. Time had been wasted. With a frustrated sigh, Yeon dropped that thought from his mind. He couldn’t focus on what was already lost, but what was now gained. A future stood before him, a new outlook on life; and how that played out was now up to them both.
Together at last.
Yeon lifted his hand from her hip, bringing it higher to caress her face. Sarang was finally stirring, bleary and disoriented from sleep. She appeared momentarily confused as to their location and embrace, but didn’t wish to fight it. Yeon’s name tumbled from her lips, mumbled awkwardly in her tired state of mind. Yeon could only smile and continue to touch her. He pushed the mess of hair from her eyes, meeting them, and reading that same desire he held.
Yeon wanted to kiss her, to feel those soft lips against his own— and he did just that.
Sarang was quick to respond, melting beneath his warm lips. She moaned between kisses and gasps for breath, and he greedily swallowed each delightful sound she would emit. His hand crept closer, a thumb nudging past her lip, urging her to open wider so that his tongue could explore. Yeon deepened the kiss, tongues entwining, drawing back only to suck and bite on her bottom lip.
Yeon shifted his weight, rolling on top of the other, towering above Sarang as their kisses continued. His hands began unbuttoning her shirt with haste, only drawing away from her lips to continue down. Lips moved to her cheek and jawline, trailing along her neck, kissing and sucking on the skin he discovered. By the time her shirt was undone, Yeon pushed it open, hands roaming over her skin. Sarang was shivering beneath him, overwhelmed by the stimulation of his touch. Yeon hummed against her skin, discovering so many new, sensitive places, and committing them to memory.
Once he’d passed her collar bone, Yeon froze. There, strewn across Sarang’s chest, was a painful reminder of their past. A large, faded scar. Something he’d done by his own blade. It begun on the top right of her chest, just beside the collar bone, heading down to the left, before trailing off. Yeon ran a finger across it, dipping over her right breast and below the left, all the way to her hip. He exhaled, taking ownership of his mark. He leant in, kissing down the length, feeling Sarang quiver beneath him. By the time he reached the end, his hands found her hips, gripping them tightly, possessively, keeping her in place.
Clothing was getting in the way. Yeon met her eyes, convinced her pupils were shaped like hearts. She watched on with parted lips, heart beating so loudly that Yeon could feel it beneath his fingertips. His hands slid up her sides, forcing her bra up and out of the way; releasing her small, delicate breasts. He licked his lips, cupping them easily with his large hands, focusing on the sounds Sarang made as he continued; rubbing and pinching, squishing and pulling her nipples. She gasped when he placed his lips around one, suckling on it gently, increasing pressure gradually, teasing her hardened nipple between teeth.
Yeon released her once she called his name desperately, hands digging into his hair. He grinned, crawling back up to face her, capturing Sarang’s neglected lips with his own, kissing her deeply. A knee slipped between her thighs, and Yeon’s hand followed; rubbing her softly above her panties. He swallowed down her moans, adding more pressure as he rubbed against her clit, driving her mad with need. Yeon dreamt this moment would be slow and steady, but patience had disappeared from him completely. Sarang’s responses to his touch weren’t helping; they were both far past waiting.
His hand quickly slipped beneath her underwear, a finger pressing between soft folds of skin. She shuddered, feeling the moment Yeon discovered her wet need, delving in without warning. Sarang tensed around him, moaning once he’d slipped inside. She was incredibly tight. Yeon would need to work her open, and with haste. He’d been painfully hard since the moment he woke. Friction was yearned for. Her heat was so enticing. Could his cock really fit inside? He hoped so. He hoped she wanted him. And the way she reacted to every twist and turn of his finger lead him to believe they were on the same wavelength.
Yeon needed more, he wanted to taste her. His mouth was watering at the thought. He slipped free, bringing his fingers to his lips. He licked them eagerly, but it wasn’t enough. It wasn’t the same as the real thing; her heat, her warmth. Sarang quickly caught on the moment he pulled away, ripping what remained of her lower clothing and pushing her thighs up high. She yelped at the sudden movement, covering her eyes in shame as her naked legs were spread wide apart, exposing herself directly in front of her oppa’s eyes. He simply smirked, placing a tender kiss to her clit, before his tongue delved inside her inviting pussy, as deep as he could possibly go.
Sarang couldn’t do anything other than moan around his name, begging him on for more; to go deeper, harder, driving her closer to the edge. Yeon closed his eyes, fucking her with his tongue, adding in a thumb alongside to help open her up to him. Her scent was delicious; insides wet and twitching, in desperate need of his cock. Yeon pulled back with a lick of his lips, delighted by the sight on offer. She was so beautiful beneath him, and more importantly— she was finally ready to take him.
Yeon’s cocked twitched with anticipation. He couldn’t wait any longer. He needed her more than ever. To be inside her. To bring forth pleasures never experienced before. To share their first time with one another. And most of all— to create a child from their union. Then hopefully, more. A family. A future. Something built together. Staying by each other’s side. No one could tear them apart.
Sarang was panting heavily, wordlessly reaching out to him with both arms. “Oppa,” she cried out, begging Yeon to hold her. “Please...”
He kissed her again, sighing into her tender touch. Those arms curled around him, and he settled in close. Yeon pulled away momentarily, though he wished to stay, it was only to connect. One hand caught under her left leg, pushing it higher, opening her up for him. Yeon held his cock in the other, knees shuffling closer, and finally sinking inside Sarang’s untouched, welcoming warmth. With the tip inside, he leant in again, watching her expression closely. Yeon spoke her name softly, caressing her face, requesting she hold on tight for what was ahead of them.
Yeon continued, watching in amazement as Sarang adjusted to the full size of his cock. It seemed impossible, yet here they were, fitting together as if they were meant to be. They shared a satisfying groan once he was completely inside, engulfed by her burning body, gripping him tightly. If there was pain, she didn’t voice it. They were both desperate, wanting to be closer, to mate, to draw forth pleasure and lose themselves into primal instincts. Anything else seemed irrelevant; their focus being only on the other.
His hips began to move. Slowly, at first; although Yeon barely lasted a few seconds before his patience wore thin. Sarang was holding onto him, hands on his arms, moving in time with his thrusts, moans intensifying each time he sunk in deeper, thrusted harder, and hit a particularly sensitive spot. He could hardly hold himself back when before such a beautiful sight. He had to see more.
With a tight grasp on her hips, he lost himself to the sensation and rhythm.
They were already fucking at an insane pace. Yeon could hardly believe it. He hadn’t realised just how pent up he’d become after all these centuries. He couldn’t get enough of his dongsaeng. Her expression, her sounds, her enticing body. They were making up for lost time. Mating like animals. Yeon couldn’t wait for what the future would hold. The sooner she conceived, the sooner they could welcome their child into the world, and start work on the next, and the next...
Yeon had been such an idiot. He’d nearly lost Sarang again, and yet, he’d somehow been given a another chance, an opportunity to redeem himself. Her body fit his perfectly. They were two parts of a single whole. There was still so much left unsaid. Yeon’s heart ached with mixed emotions; so much love, to an overpowering degree. He tried and fail to voice it, but she understood. There was no greater way of showing one’s love than this.
His Sarang. His father’s precious gift.
It wouldn’t be long now. Yeon was panting hard, trying to focus and breathe at the same time. Sarang was driving him crazy with need. She was tightening around him, moaning and calling his name, fingers digging into his back. He couldn’t take much more of this. A pressure was building up in the pit of his stomach. Yeon had never been this aroused in his life, convinced a pleasure this intense was impossible. He was determined now; intent to fill his newfound mate to the brim, milk his cock for every possible drop, ensuring she’d soon conceive. He had to see the expression on his face when she came—
And that last thought alone was enough to send Yeon over he edge.
A final, brutal thrust sealed them together, hips flush against hips. Sarang threw her head back with a cry; the two of them coming within seconds of one other. The way she tightened further around him kept Yeon in place as he rode out his orgasm, coming harder than ever before, deep inside his lover. Kisses resumed, bodies together, slowly coming down from their joint high. Touches were electrifying, moans gradually returning to words, yet desires remained unquenched.
Sarang’s hand slipped between them, directly where they were connected. She was touching between her legs, feeling Yeon’s cock where it disappeared inside her, desperate to remain connected. “Oppa...” She murmured, crossing her weakening legs around his hips, keeping him in place.
Yeon chuckled, not intent on moving either. “Don’t worry, my dear Rang-ah,” he said breathlessly, nuzzling against her neck. His cock twitched inside her, hardening again, ready and waiting for another round. “I’m not done with you yet.”
Their lips collided and he began thrusting slowly and shallowly, enjoying every second of their connection; convinced that he was in heaven. This was only the first of many rounds he had in store for his beloved dongsaeng; he only hoped she’d be able to keep up with him in the meantime.
