A Commission Series For My Friend @thelastsequence Here On Tumblr. Hope you Enjoyed the First Part of This Series Bruv.

You’ve always taken your role as an older brother seriously. From the time you were just a boy, you understood that Sullin, your little sister, relied on you more than anyone else. Your parents were rarely home—work trips, late nights, or social obligations kept them away. So, you became her pillar. When she cried, you were there to wipe her tears. When she was lonely, you told her stories to make her smile. You were her everything, and she was yours.

As the years went by, Sullin blossomed into a stunning young woman. She was the kind of girl people couldn’t help but notice—bright, kind, and impossibly beautiful. At school, she became a magnet for attention. You’d heard the stories from her about boys confessing their feelings or trying to win her heart, but Sullin never seemed interested.

“They’re nice, but… they’re not you, oppa,” she would say with a soft giggle. Her words always felt like an innocent declaration of her admiration, but the way her eyes lingered on you sometimes made you wonder if there was more behind them.

Today started out like any other day. You walked home from work, checking your phone for texts from Sullin. She always messaged you when she was done with school, and you’d meet her halfway or wait for her at home. But today, there were no texts. No updates.

A feeling of unease settled in your chest as you quickened your pace toward her school.

When you arrived, you saw her standing near the gates, her arms crossed and her body tense. Her usual cheerful demeanor was replaced with discomfort, and a tall boy stood in front of her, gesturing animatedly. His voice reached your ears as you approached.

“Sullin, come on. I’m not like those other guys. I really like you. We’d be great together. Just give me a chance.”

The boy’s persistence made your blood boil. Sullin’s polite rejection wasn’t enough for him. She tried to step back, but he matched her movement, his presence invasive. You quickened your pace, your fists clenched tightly.

“I said no, Juwon,” Sullin replied firmly, though her voice wavered slightly. “Please, just leave me alone.”

Before the boy could respond, you stepped in, placing yourself between him and your sister.

“She said no. Are you deaf, or just stupid?” you growled, your eyes locking onto Juwon’s with an intensity that made him flinch.

Juwon took a step back, his confidence faltering. “I… I wasn’t doing anything wrong. I just wanted to talk to her.”

“You don’t seem to understand the meaning of no,” you snapped, your voice low and dangerous. “If she says she’s not interested, you leave her alone. Got it?”

Juwon glanced at Sullin, who was peeking out from behind you, her hands clutching your arm tightly. Her expression was a mix of fear and relief. With a frustrated grunt, Juwon turned on his heel and walked away, muttering under his breath.

As soon as he was gone, Sullin exhaled shakily and leaned into you. “Oppa…” she murmured, her voice soft and trembling.

You turned to her, your expression softening. “Are you okay? Did he hurt you?”

She shook her head, her hands still clutching your arm. “No, he didn’t. But… thank you. I don’t know what I would’ve done if you hadn’t shown up.”

Her bright eyes met yours, and a small, grateful smile spread across her face. “You always show up when I need you the most.”

You reached out and gently ruffled her hair. “That’s what big brothers are for.”

Sullin giggled and slipped her hand into yours, intertwining your fingers. The gesture was something she’d done since she was little, but as she grew older, it started to feel different—more intimate.

“Let’s go home,” she said cheerfully, as if the encounter with Juwon had never happened. Her mood shifted so quickly it almost made you laugh.

As you walked together, Sullin chatted about her day, her voice light and happy. But you couldn’t shake the feeling of unease. Something about the way Juwon looked at her bothered you deeply. His persistence, his unwillingness to take no for an answer—it wasn’t something you could ignore.

When you reached home, Sullin kicked off her shoes and flopped onto the couch. “Oppa, can we order takeout tonight? I don’t feel like cooking.”

You chuckled and set your bag down. “Fine, but only if you help me pick what to order.”

She grinned and pulled out her phone, scrolling through the menu. As you watched her, a sense of protectiveness swelled in your chest. Sullin was your responsibility, your precious little sister. You’d do anything to keep her safe, no matter what.

But deep down, you couldn’t ignore the nagging thought that maybe, just maybe, Sullin saw you as more than her brother. The way she clung to you, the way her eyes lit up when you were around—it was different.

And maybe, if you were honest with yourself, you didn’t mind.

Life returned to normal after the encounter with Juwon—or as normal as it could be with Sullin practically glued to your side. At first, her constant presence felt comforting. You’d always been close, and it wasn’t unusual for her to seek you out for advice or companionship. But now, it was different.

She was always there.

When you made breakfast in the morning, she was in the kitchen, sitting on the counter and watching you intently. When you came home from work, she was already waiting by the door, her face lighting up like a child’s on Christmas morning. Even when you tried to relax, she was either nestled beside you or finding excuses to talk.

“Oppa, can you help me with this?”

“Oppa, I made you some tea. It’s your favorite!”

“Oppa, do you want to watch a movie with me tonight?”

You couldn’t deny that you enjoyed her company. Sullin had a way of making everything feel lighter, her presence chasing away the exhaustion from your long days. But as time went on, you started to worry.

She didn’t seem to have any friends.

Sure, she was polite to her classmates and had plenty of admirers, but she never talked about hanging out with anyone outside of school. And she certainly wasn’t interested in dating, much to the dismay of her many suitors.

One evening, as you sat on the couch scrolling through your phone, Sullin plopped down beside you, resting her head on your shoulder. You glanced at her, raising an eyebrow. “Don’t you have homework to do?”

She pouted. “I finished it already. Besides, I’d rather spend time with you.”

You sighed, setting your phone aside. “Sullin, don’t you think you should try hanging out with your friends more? You’re in high school—you should be making memories, having fun.”

She frowned, pulling away slightly. “I don’t need anyone else, oppa. I’m happiest when I’m with you.”

Her words hit you like a punch to the gut. On the surface, it sounded sweet, but there was an undercurrent of something else, something possessive.

“That’s not healthy, Sullin,” you said gently. “It’s important to have other people in your life. You don’t want to look back and regret missing out on these years.”

She crossed her arms, her expression stubborn. “I won’t regret it. Everyone else is boring or annoying. You’re the only one who understands me.”

You sighed, running a hand through your hair. “Sullin, you’re my little sister. Of course I’ll always be here for you, but I can’t be your entire world. You need to experience life, meet new people…”

Her eyes darkened, and for a moment, the cheerful facade she always wore cracked. “Are you trying to get rid of me, oppa?”

The question made your heart sink. “No, of course not. I just want what’s best for you.”

“Then stop trying to push me away,” she said, her voice trembling. “You don’t understand, oppa. You’re the only one who’s ever been there for me. Mom and Dad were never around, and everyone else just wants something from me. But you… you’re different. You care about me.”

Her words were raw, filled with emotion, and you felt a pang of guilt. She wasn’t wrong. You had been her rock, her protector. But now, it seemed like that bond was becoming a chain, binding her to you in a way that felt… unnatural.

“Sullin…” you began, but she cut you off.

“Please, oppa,” she said, her voice barely above a whisper. “Don’t ask me to change. I’m happy like this. Aren’t you?”

You didn’t know how to answer. You were happy in a way, but the weight of her dependence was growing heavier by the day. Still, seeing the vulnerability in her eyes, you couldn’t bring yourself to push her away.

“Alright,” you said finally, your voice soft. “But promise me you’ll at least try to talk to your classmates more. You don’t have to make best friends, but it’s good to have people you can rely on.”

She hesitated before nodding. “Okay. I’ll try… for you.”

Her smile returned, but there was something about it that unsettled you—a flicker of triumph, as if she’d won a battle you didn’t even know you were fighting.

The rest of the evening passed quietly. Sullin insisted on sitting as close to you as possible while you watched TV, her head resting on your shoulder. She seemed content, but your thoughts were elsewhere.

You couldn’t shake the feeling that your relationship with her was crossing into dangerous territory. You wanted to protect her, to make her happy, but at what cost?

As the night wore on, you found yourself wondering if you’d made a mistake. Had you been too soft? Too accommodating?

Or was it already too late to pull away?

Day by day, your routine with Sullin became more structured, more predictable. Every morning, you would walk her to school, and every afternoon, you would wait by the gates to take her home. It had become a ritual, one that Sullin seemed to cherish deeply.

She always greeted you the same way after school—with a bright, radiant smile and an enthusiastic wave. Her happiness was contagious, and though you still worried about her dependence on you, you couldn’t help but feel a sense of pride knowing that you were the one who made her feel safe and loved.

One afternoon, as you leaned against the gate, watching the students filter out, you spotted Sullin walking toward you. This time, she wasn’t alone. Two girls were by her side, chatting animatedly. Sullin’s face lit up even more when she saw you, and she quickly waved, tugging her friends along.

“Oppa!” she called, her voice ringing with excitement.

The two girls looked at you curiously before offering polite smiles.

“This is Dahyun and Lynn,” Sullin introduced, gesturing to the two girls. “They’re my best friends.”

“Nice to meet you,” Dahyun said with a slight bow. She was petite with short, dark hair and an energetic aura that made her seem like the life of the group.

“Hello,” Lynn added softly, her demeanor more reserved. Her long, wavy hair framed her face, and she had a calming presence that balanced Dahyun’s energy.

“Nice to meet you both,” you replied with a nod, smiling at how polite they were.

The trio looked adorable together, and for the first time in a while, you felt a glimmer of relief. Maybe Sullin was starting to open up to others after all.

“We were just talking about going to the library together tomorrow,” Dahyun said. “Sullin said she wanted to show us some books she likes.”

You raised an eyebrow at Sullin, who blushed slightly. “I thought it’d be fun,” she said shyly.

“Sounds like a good idea,” you said. “It’s nice to see you making friends, Sullin.”

She smiled, her cheeks tinged pink, and glanced at her friends. “Yeah… it’s been nice.”

Dahyun suddenly turned to you with a playful grin. “Sullin talks about you a lot, you know. She’s always saying how cool and dependable her oppa is.”

“Dahyun!” Sullin exclaimed, her face turning red.

You chuckled, feeling both flattered and a little embarrassed. “Well, I try my best.”

Lynn smiled gently. “She’s lucky to have someone like you.”

Sullin beamed at their words, clinging to your arm as if to emphasize the bond you shared. “I know, right? Oppa is the best.”

Though her affection was endearing, you noticed the slight possessiveness in the way she held onto you, as if she were silently reminding her friends that you were hers.

After a few more minutes of light conversation, Dahyun and Lynn said their goodbyes and headed off in the opposite direction. Sullin waved to them cheerfully before turning her attention back to you.

“They’re nice, aren’t they?” she asked, her voice soft.

“Yeah, they seem great,” you replied. “I’m glad you’ve made some good friends.”

Sullin’s smile faltered for a brief moment before returning, though it felt a bit forced. “Yeah… they’re fun to hang out with. But I still like being with you the most.”

You sighed, giving her a gentle pat on the head. “Sullin, it’s good to have friends your age. It’s part of growing up.”

“I know,” she murmured, though her tone was unconvincing.

The walk home was quieter than usual, and you couldn’t help but wonder if your comment had upset her. You wanted her to live a full, happy life, but it was clear that she still saw you as the center of her world.

The next day, you dropped her off at school as usual. Dahyun and Lynn were waiting for her at the gates, and they greeted her with warm smiles. Sullin waved to you before running off to join them, her laughter echoing as they disappeared into the building.

For a moment, you felt a sense of pride. Maybe things were changing, even if only slightly.

But as you walked away, you couldn’t shake the feeling that Sullin’s attachment to you ran deeper than you fully understood. She had friends now, but would that be enough to loosen the hold she had on you—or the hold you had on her?

You didn’t have an answer, but you knew one thing for sure: Sullin wasn’t ready to let go.

The night was still and quiet, but something felt… off. You stirred awake, a strange warmth pressing against your body. Groggily, you reached for your blanket, only to freeze when you felt something—someone—next to you.

Blinking in the dim light, your eyes adjusted to the sight of Sullin, curled up against your side, her head resting on your chest. Her breathing was soft and steady, indicating that she was fast asleep.

“Sullin…?” you whispered, unsure if this was some kind of dream.

She didn’t respond. Her arms were wrapped around you tightly, as though she were holding on to a lifeline.

You tried shaking her gently. “Sullin, wake up. What are you doing here?”

But she didn’t budge. Her grip remained firm, and her peaceful expression made it clear she was deep in slumber.

A part of you wanted to get up and carry her back to her own bed, but the thought of waking her—of seeing her disappointed or upset—held you back. With a heavy sigh, you leaned back against the pillows and closed your eyes, hoping sleep would come quickly.

“This is just one night,” you told yourself. “It doesn’t mean anything.”

But as you drifted off, the faint scent of her shampoo lingered in the air, and you couldn’t ignore the strange unease settling in your chest.

Morning came sooner than you expected. The first rays of sunlight peeked through the curtains, and you yawned as you stretched, running a hand through your messy hair. Turning to your side, you saw that Sullin was still in bed, her face serene as she lay curled up beneath the blanket.

You rubbed your eyes and stood up, deciding to let her sleep a little longer. The events of the night before played in your mind, but you shook them off. “She probably just had a bad dream,” you muttered, trying to convince yourself.

Grabbing a fresh towel, you headed to the bathroom for a shower. The sound of running water filled the room as you tried to clear your thoughts.

But what you didn’t realize was that Sullin wasn’t asleep at all.

Her eyes fluttered open the moment she heard you move. She sat up quietly, watching as you left the room. Her gaze was fixed, her lips curling into a faint smile.

Sliding out of bed, she tiptoed to the door, peeking through the small crack you’d left open. The faint sound of water accompanied the sight of steam escaping from the bathroom.

Sullin leaned against the doorframe, her hands clasped together as she watched the outline of your figure behind the frosted glass. Her eyes traced your movements, studying the way the water cascaded down your body.

“You don’t even realize it, do you, oppa?” she murmured under her breath, her voice barely audible over the sound of the shower. “How much I need you. How much I love you.”

Her heart raced as she stood there, completely captivated. Every little thing about you—your voice, your presence, the way you cared for her—drove her deeper into her obsession.

When she heard the water turn off, she quickly darted back to the bed, slipping under the covers and feigning sleep.

You stepped out of the bathroom, towel draped around your neck as you dried your hair. “Sullin, time to get up,” you called out, glancing at her still figure.

She stirred slowly, rubbing her eyes as though she’d just woken up. “Morning, oppa,” she mumbled, her voice sweet and innocent.

“Morning,” you replied, grabbing your clothes for the day. “You slept well, huh?”

She nodded, sitting up and stretching. “I always sleep well when I’m with you.”

Her words caught you off guard, and you hesitated for a moment before brushing it off. “You shouldn’t make a habit of that,” you said lightly. “You’ve got your own bed for a reason.”

“But I like being close to you,” she replied, her tone playful but with a hint of sincerity. “It makes me feel safe.”

You sighed, running a hand through your hair. “Sullin, you can’t keep doing this. What if people found out? They’d think it’s… strange.”

Her smile faltered for a brief moment, but she quickly recovered. “Who cares what other people think? It’s not like they understand us, oppa.”

Her words left you uneasy, but you didn’t want to press the issue further. “Just… don’t make it a habit, okay?”

She tilted her head, studying you with an intensity that made your skin prickle. “Okay, oppa,” she said softly, though her tone carried a subtle edge of defiance.

As you turned away to finish getting ready, you couldn’t shake the feeling that something had shifted. Sullin’s actions, her words—they were starting to blur the lines of your relationship.

And deep down, you feared what might happen if things continued down this path.

The morning passed with relative ease. Sullin had been in high spirits, eagerly talking about her plans with Dahyun and Lynn for their trip to the central library. You couldn’t help but admire how animated she looked—her bright eyes, her infectious laugh. It was a side of her you hadn’t seen often enough.

When it was time, you pulled up in front of her school, where the trio was waiting. Sullin was the first to spot you, waving enthusiastically as she pulled her friends along.

“Oppa!” she called, opening the door and sliding into the passenger seat. Dahyun and Lynn followed, squeezing into the back.

“Thanks for taking us, oppa,” Sullin said, her voice laced with excitement.

“It’s no problem,” you replied, forcing a smile. “Ready for your library adventure?”

“Absolutely!” Dahyun chirped. “I’ve been wanting to check out their art book collection. They’re supposed to have some amazing ones.”

“And I heard they have a rare first edition of a poetry collection,” Lynn added softly, her tone dreamy.

As the girls chatted, your focus remained on the road, but you couldn’t ignore the occasional glance Sullin threw your way. She giggled softly every time your eyes met hers, her gaze lingering a little too long for comfort.

“What’s so funny?” you asked, raising an eyebrow.

“Nothing,” she replied, stifling another giggle. “You just look cute when you’re focused.”

The comment made Dahyun and Lynn laugh, but you felt a strange pang in your chest. It wasn’t the teasing itself—Sullin had always been playful with you—but something about the way she said it felt… different.

You shook the thought away, reminding yourself that this was her moment to enjoy with her friends. The last thing you wanted was to ruin it by overthinking.

As you pulled up in front of the central library, the girls clambered out of the car, their excitement palpable.

“Alright, you three,” you said, leaning out the window. “Behave yourselves and stay together. Be wary of strangers, okay?”

“Got it, oppa,” Sullin said with a bright smile.

“Thanks for driving us,” Dahyun added, her tone cheerful.

“We’ll be careful,” Lynn said softly, bowing slightly.

The three of them waved as they headed toward the library entrance, their laughter echoing behind them.

You watched them disappear inside before pulling away, your mind wandering back to the strange feeling that had been gnawing at you all morning.

Why had your heart skipped a beat when Sullin had smiled at you in the car? Why did her giggle linger in your mind like a haunting melody?

You clenched the steering wheel, trying to push the thoughts away. This is wrong, you told yourself. She’s your sister. You’re just tired. That’s all.

Back at home, the silence felt both comforting and oppressive. You tried to distract yourself with chores and TV, but the memory of Sullin’s gaze kept creeping in.

Finally, exhaustion won out, and you decided to take a nap. The events of the previous night—Sullin curling up beside you, her restless movements—had left you more drained than you realized.

You lay down on the couch, closing your eyes. “Just a quick nap,” you muttered to yourself.

But sleep didn’t come easily. Your mind replayed moments you didn’t want to dwell on—Sullin’s smile, the way she clung to your arm, her soft voice calling you “oppa.” Your chest tightened, and your heart began to race.

“No,” you whispered to yourself, gripping the pillow. “Stop thinking about this.”

Eventually, the weight of fatigue pulled you under, and you drifted into a dreamless sleep.

When you woke, the sun was already starting to dip below the horizon. You checked the time and realized it was time to pick the girls up.

The drive back to the library was quiet, the hum of the car engine filling the empty space in your thoughts. You tried to focus on the road, but anticipation gnawed at you.

When you arrived, the three girls were waiting outside, their faces lighting up as you pulled up. Sullin opened the passenger door and climbed in, her smile as radiant as ever.

“Oppa!” she said cheerfully. “Did you miss us?”

“Of course,” you replied, keeping your tone light.

Dahyun and Lynn climbed into the backseat, both carrying small bags filled with books.

“Thank you for picking us up,” Lynn said politely.

“We had so much fun,” Dahyun added. “The library was amazing!”

As the car filled with their chatter, you felt a mix of relief and unease. Sullin seemed happy, which was all you wanted for her. But the strange, unshakable feeling in your chest reminded you that something wasn’t right.

And as you glanced at Sullin out of the corner of your eye, catching the way she was looking at you—her smile soft, her gaze warm—you couldn’t help but wonder if she felt it too.

The ride back home was filled with lighthearted chatter. Dahyun and Lynn shared stories about their favorite finds at the library, their voices brimming with excitement. Sullin, however, leaned back in her seat, her head tilted slightly toward you as she listened quietly, a serene smile on her lips.

When you pulled into the driveway, the three of them thanked you warmly. Dahyun and Lynn waved goodbye as they headed home, leaving you and Sullin standing by the front door.

“I’m so tired,” Sullin groaned dramatically as she kicked off her shoes. She trudged toward her room and flopped onto her bed, spreading her arms and legs like a starfish.

You leaned against the doorframe, chuckling at the sight. “Didn’t you just sit around reading books all day? How are you this exhausted?”

She pouted, her cheeks puffing up. “Oppa, reading is hard work! Especially when you’re explaining everything to your friends.”

“Oh, is that right?” you teased, stepping closer to ruffle her hair.

“Oppaaa!” she whined, swatting at your hand but making no real effort to stop you. Her cutesy tone made you laugh even more.

“Alright, alright,” you said, raising your hands in mock surrender. “Get some rest, okay? Goodnight, Sullin.”

“Goodnight,” she murmured, her voice soft as her eyes began to flutter shut.

Satisfied, you left her room and headed to yours. The day had been long, and despite the strange feelings swirling in your chest, you were utterly drained.

You slipped under the covers, sighing as the quiet of the house enveloped you. For a moment, everything felt still—peaceful.

But as you stared up at the ceiling, the silence began to grow heavy, almost oppressive. Memories of the day flashed through your mind: Sullin’s giggles in the car, the way her eyes lingered on you, the warmth of her smile.

Your heart thudded in your chest, an uncomfortable rhythm that refused to settle.

“It’s nothing,” you whispered to yourself. “You’re just overthinking.”

Yet, the more you tried to push the thoughts away, the stronger they came back. You rolled onto your side, burying your face in the pillow in frustration.

The night dragged on, and just as you were on the edge of sleep, a faint creak broke the silence.

Your eyes shot open. For a moment, you thought you’d imagined it. But then, there it was again—a soft, deliberate sound, like footsteps on the wooden floor.

Your breath hitched as you turned your head toward the door. It was open, just a crack, and through the sliver of space, you thought you saw a shadow shift.

“Sullin?” you called out, your voice low but steady.

There was no response.

Pushing yourself up, you hesitated before swinging your legs over the side of the bed. The house was dark, the faint glow of moonlight spilling through the windows.

You stepped toward the door, opening it fully. The hallway was empty, silent except for the faint hum of the refrigerator in the kitchen.

“Must’ve been the wind,” you muttered, though the explanation felt hollow.

Closing the door, you returned to bed, your unease lingering like a shadow in the corner of your mind.

And as you lay there, trying to calm your racing heart, you couldn’t shake the feeling that you weren’t alone.

“Brother?” Her voice was barely above a whisper, trembling with a mix of hesitation and something darker, something hungrier.

You didn’t respond. You couldn’t. Your body was still, your eyes closed, but your mind was racing. The sound of her footsteps, soft and deliberate, crept closer to your bed. The air felt heavier, thick with tension, as if the room itself was holding its breath.

She stopped just beside you, her presence looming even in the darkness. You could hear her shallow breathing, the faint rustle of her nightgown as she shifted her weight. And then, the unmistakable sound of your blanket being pulled back, the cool air hitting your skin.

Your heart pounded in your chest, but you kept your breathing steady, feigning sleep. You couldn’t let her know you were awake. Not yet.

Her fingers brushed against your waistband, and you felt your stomach clench. Slowly, carefully, she tugged at the fabric, pulling your pants down just enough to release your cock. The air was cool against your exposed skin, but the heat of her gaze was overwhelming.

“So perfect,” she murmured, her voice shaking with awe. You felt her breath, warm and unsteady, against your skin as she leaned in closer. Her hand wrapped around you, her touch tentative at first, then firmer, more deliberate.

You had to bite back a groan as she began to stroke you, her fingers exploring every inch of you. Her breath hitched, and you could hear the soft, desperate sounds she was making as she worked you in her hand.

“I’ve wanted this for so long,” she whispered, her voice thick with emotion. “You have no idea how much I’ve thought about this—about you.”

Her words sent a jolt through you, a mix of guilt and desire that made your head spin. You had always known there was something off about the way she looked at you, the way she clung to you. But you had never let yourself acknowledge it, never allowed yourself to think about what it might mean.

And now, here she was, her hand moving with a confidence that belied her inexperience, her breath hot against your skin as she leaned in even closer. You felt her lips brush against the tip of your cock, and you had to clench your fists to keep from giving yourself away.

“Please, brother,” she whispered, her voice barely audible. “Let me do this for you.”

And then, her lips parted, and she took you into her mouth.

The sensation was overwhelming, her warmth enveloping you, her tongue swirling around you as she experimented with different movements. She was inexperienced, her technique clumsy, but the sheer desperation in her actions made it impossible to resist.

You couldn’t help it—you let out a soft moan, your hips shifting slightly as you responded to her touch. She paused for a moment, her breath catching, and you could feel her heart racing as she realized you were awake.

But she didn’t stop. If anything, she seemed emboldened, her movements growing more confident as she worked you in her mouth. Her hand moved to the base of your cock, stroking you in time with the movements of her lips, her tongue swirling around the tip in a way that made your toes curl.

“Sullin,” you breathed, your voice barely audible. Her name slipped out before you could stop yourself, and she froze for a moment, her lips still wrapped around you.

Slowly, she pulled back, her breath coming in shallow gasps as she looked up at you. Her eyes were wide, filled with a mix of fear and longing, and her cheeks were flushed with embarrassment.

“You’re… awake,” she whispered, her voice trembling.

For a moment, neither of you said anything. The silence between you was deafening, the weight of what had just happened hanging in the air like a storm cloud.

And then, without warning, she leaned in again, her lips closing around you once more. This time, there was no hesitation, no uncertainty. Her movements were deliberate, her tongue swirling around you in slow, deliberate circles as she took you deeper into her mouth.

“Sullin, wait—” you started, but the words caught in your throat as she reached up, her fingers tangling in the sheets as she worked you with her lips and tongue.

You couldn’t stop yourself—your hips shifted, thrusting into her mouth as the sensations overwhelmed you. She didn’t pull away, didn’t stop. Instead, she let out a muffled moan, her eyes closing as she lost herself in the act.

The room was filled with the sounds of her efforts, the wet, messy sounds of her mouth working you, the soft, desperate noises she made as she pleasured you. Her cheeks hollowed as she took you deeper, her lips moving with a rhythm that made your head spin.

“Sullin,” you groaned her name lowly, a mix of guilt and ecstasy coursing through your veins. You’d always loved her, always cared for her, but this… this was something else entirely. Something forbidden, something dangerous._

And yet, you couldn’t bring yourself to stop her.

You groaned, your hands instinctively reaching for her as she pulled away from your cock, her lips wet and glistening in the moonlight. Sullin looked up at you, her eyes dark with desire, her breathing heavy.

“I… I can’t stop,” she whispered, her voice trembling. “I need more.”

Before you could respond, she climbed onto the bed, straddling you. Her nightgown rode up, revealing her bare thighs as she positioned herself over your hard cock. You could feel the heat radiating from her, the way her body trembled with anticipation.

“Sullin,” you said, your voice strained. “This… this is wrong.”

“I don’t care,” she replied, her voice firm. “I’ve wanted this for so long, brother. I’ve dreamed about it, fantasized about it. I can’t hold back anymore.”

Her words sent a shiver down your spine, a mix of guilt and arousal flooding your veins. You wanted to stop her, to push her away, but your body betrayed you. Your hands gripped her hips, holding her in place as she lowered herself onto your cock.

She gasped as you entered her, her head tilting back as she sank down, taking every inch of you. You groaned, the sensation overwhelming, the warmth of her body enveloping you completely.

“You feel so good,” she moaned, her voice breathless. “I’ve always wondered… what it would feel like to have you inside me.”

Her hips began to move, slowly at first, as she adjusted to your size. You could feel her tightness, the way her muscles clenched around you, pulling you deeper with every thrust.

“Sullin,” you groaned, your hands tightening on her hips. “This… this can’t happen.”

“But it is happening,” she whispered, leaning forward so her lips were just inches from yours. “And you don’t want it to stop, do you?”

You hesitated, your mind a whirlwind of conflicting emotions. But then she moved again, her hips rolling against yours, and all thought fled your mind. All you could feel was her, the way she moved, the way she felt.

“Tell me you want me,” she begged, her voice soft yet demanding. “Tell me you’ve thought about this too.”

You looked up at her, your eyes meeting hers in the dim light. And in that moment, you couldn’t deny it any longer.

“I’ve thought about it,” you admitted, your voice rough with desire. “I’ve wanted you, Sullin. I’ve wanted this.”

A smile spread across her face, one of pure joy and triumph. “Then take me,” she said, her voice low and sultry. “Make me yours.”

Her words were like a spark, igniting something deep within you. Your hands moved from her hips to her ass, gripping her firmly as you thrust up into her. She cried out, her body arching as you filled her completely.

“Yes,” she moaned, her voice trembling with pleasure. “Just like that.”

Her hips moved faster, matching your rhythm as you fucked her. The sounds of your bodies colliding filled the room, the wet slap of skin on skin, her breathless gasps and moans.

“I’ve dreamed about this,” she whispered, her voice barely audible over the sound of your bodies moving together. “I’ve imagined you inside me, fucking me just like this.”

Her words sent a jolt of heat through you, your cock throbbing inside her. You couldn’t believe how good it felt, how right it felt, even though you knew it was wrong.

“I’ve imagined you pinning me down, taking me whenever you wanted,” she continued, her voice growing more desperate. “I’ve imagined you filling me with your cum, marking me as yours.”

“Sullin,” you groaned, your hips thrusting harder, faster. “You don’t know what you’re saying.”

“I do,” she insisted, her hands gripping your shoulders as she rode you. “I’ve wanted this for so long, brother. I’ve wanted you.”

Her words were like a drug, intoxicating and irresistible. You couldn’t stop yourself, your hands moving to her breasts, kneading them through the thin fabric of her nightgown. She moaned, her head falling back as you teased her nipples, her body moving faster, more desperate.

“I’m yours,” she gasped, her voice trembling with need. “I’ve always been yours.”

Her words pushed you over the edge, your cock throbbing as you felt your release building. You tried to hold it back, to prolong the moment, but she was too much, her body too perfect, her words too enticing.

“I’m going to cum,” you groaned, your hands gripping her hips as you thrust into her one last time.

She cried out, her body trembling as she came around you, her muscles clenching tight as she reached her own climax. You felt your release surge through you, your cock pulsing as you filled her with your cum.

For a moment, everything was still, the two of you locked together as the waves of pleasure washed over you. Then, slowly, she collapsed onto your chest, her body trembling as she tried to catch her breath.

You held her, your hands stroking her back as you both came down from the high. You knew this was wrong, that it shouldn’t have happened, but in that moment, you couldn’t bring yourself to care. All that mattered was her, the way she felt in your arms, the way she made you feel.

“Brother,” she whispered, her voice soft and filled with emotion. “I love you.”

You hesitated, your mind still reeling from what had just happened. But as you looked down at her, at the way she looked at you, you couldn’t deny the truth any longer.

“I love you too, Sullin,” you admitted, your voice rough with emotion. “I always have.”

She smiled, her eyes closing as she nuzzled against your chest. And for the first time, you let yourself believe that maybe, just maybe, this wasn’t wrong. Maybe this was exactly where you were meant to be.

But as you lay there, holding her in your arms, a small voice in the back of your mind whispered a warning. This can’t last. This can’t be real.

You pushed the thought aside, focusing instead on the way she felt in your arms, the way her body fit perfectly against yours. You didn’t know what the future held, but in that moment, you didn’t care. All that mattered was her.

“Brother,” she whispered again, her voice filled with desire. “I want more.”

The morning light filtered through the curtains, casting a soft glow over the room. Sullin was still curled up against you, her breathing steady and warm against your chest. Your fingers absentmindedly traced patterns on her back, your mind a whirlwind of conflicting emotions. Last night had been… something. Something you couldn’t quite put into words. It was intense, passionate, and undeniably wrong. Yet, it felt so right in the moment.

Her eyes fluttered open, and she looked up at you, a sleepy smile spreading across her face. “Morning,” she whispered, her voice husky with sleep.

“Morning,” you replied, your voice tight with unease. You couldn’t ignore the weight of what had happened. “Sullin, we… we need to talk.”

Her smile faltered, and she pushed herself up, her hair falling in messy waves around her face. “Talk about what?” she asked, though her tone suggested she already knew.

“About last night,” you said, sitting up and running a hand through your hair. “About… us. This can’t happen again. It’s… it’s not right.”

Her expression darkened, and she crossed her arms over her chest. “Not right? You didn’t seem to think it was wrong last night. You seemed pretty into it, actually.”

Your cheeks burned, and you looked away. “I know. I�� I don’t know what came over me. But we’re siblings, Sullin. This isn’t… we can’t.”

She leaned closer, her eyes boring into yours. “Why not? If we both want it, why does it matter?”

“It matters,” you insisted, your voice rising slightly. “This isn’t just some fling. It’s… it’s incest, Sullin. People don’t… they don’t do this.”

“People don’t do a lot of things,” she shot back, her voice sharp. “But we did. And it felt good. Don’t pretend it didn’t.”

You clenched your fists, frustration bubbling up inside you. “Of course it felt good. That’s not the point. The point is, it’s wrong. We can’t keep doing this.”

She stared at you for a long moment, her expression unreadable. Then, she sighed and leaned back against the headboard. “Fine,” she said, her voice dripping with resignation. “We’ll stop. If that’s what you want.”

Relief washed over you, but it was short-lived. There was something in her tone, something that made your stomach twist. “It’s not just about what I want,” you said carefully. “It’s about what’s right.”

She gave you a small, almost sad smile. “I know. But… I can’t promise I won’t want you again. I can’t promise I won’t need you.”

Her words sent a shiver down your spine, and you felt your resolve waver. “Sullin…”

“I mean it,” she said, her voice barely above a whisper. “You’re everything to me. I’ve always wanted you, and now that I’ve had you… I don’t think I can stop.”

You swallowed hard, your heart pounding in your chest. “We have to,” you said, though your voice lacked conviction. “For both of our sakes.”

She didn’t respond immediately, her gaze drifting to the window. The room fell into a heavy silence, the weight of her words hanging in the air like a storm cloud.

Finally, she spoke again, her voice soft but firm. “I’ll try. For you, I’ll try. But… don’t expect me to stop loving you. That’s something I can’t control.”

You reached out, brushing a strand of hair away from her face. “I’m not asking you to stop loving me. I’m just asking you to… to put some boundaries in place. For both of us.”

She leaned into your touch, her eyes closing for a brief moment. “Boundaries,” she repeated, as if testing the word on her tongue. “Alright. Boundaries.”

You nodded, though you couldn’t shake the feeling that this conversation wasn’t over. Not by a long shot. “Thank you,” you said quietly.

She opened her eyes, her gaze meeting yours once more. “But just so you know… if you ever change your mind, if you ever want me again… I’ll be here. Waiting.”

Your breath caught in your throat, and you pulled your hand away, the intensity in her eyes almost too much to bear. “Sullin…”

She smiled, a small, knowing smile that sent a jolt of heat straight to your core. “I mean it,” she said, her voice low and sultry. “I’ll always be here for you. No matter what.”

You swallowed hard, your mind racing. You wanted to believe that you could resist her, that you could stick to the boundaries you’d just set. But deep down, you knew it wouldn’t be that simple.

Because the truth was, you wanted her too. More than you cared to admit.

As if sensing your inner turmoil, Sullin leaned in, her lips brushing against your ear. “Think about it,” she whispered, her breath hot against your skin. “I know you want me just as much as I want you.”

Your body reacted instantly, a surge of desire coursing through you. You tried to push her away, but your hands seemed to have a mind of their own, gripping her hips instead.

“Sullin, we… we said we’d stop,” you said, your voice shaky.

She pulled back slightly, her eyes gleaming with mischief. “I know. But maybe… just one more time? For old times’ sake?”

You hesitated, your heart pounding in your chest. This was wrong. So, so wrong. But the way she was looking at you, the way her body pressed against yours… it was impossible to resist.

“Just… one more time,” you whispered, your resolve crumbling.

She smiled, a triumphant smile that made your stomach flip. “Good,” she said, her hands already moving to your waistband. “Because I’ve been thinking about this all morning.”

You didn’t have time to respond before she was pulling down your boxers, freeing your already hardening cock. She eyed it hungrily, licking her lips.

“So perfect,” she murmured, her voice filled with awe. “I love the way you feel in my hands.”

You let out a shaky breath, your mind a whirlwind of conflicting emotions. This was wrong. You knew it was wrong. But the way she was touching you, the way she was looking at you… it was impossible to care.

She leaned down, her lips brushing against the tip of your cock. “I’ve missed this,” she whispered, her voice sending shivers down your spine.

And then, without warning, she took you into her mouth, her lips wrapping around you in a way that made your toes curl.

“Sullin…” you groaned, your hands tangling in her hair.

She moaned around you, the vibrations sending waves of pleasure through your body. Her tongue swirled around the tip, teasing you in all the right ways.

You tried to hold back, tried to keep things under control. But it was impossible. She was too good, too eager, and before you knew it, you were thrusting into her mouth, your hips moving of their own accord.

She didn’t seem to mind, her hands gripping your thighs as she took you deeper, her throat relaxing to accommodate you.

“Fuck, Sullin…” you gasped, your fingers tightening in her hair. “You’re so good at this.”

She pulled back slightly, looking up at you with hooded eyes. “Do you like it?” she asked, her voice dripping with innocence.

“Yes,” you breathed, your hips thrusting upward again. “I love it.”

She smiled, a mischievous smile that made your heart race. “Good,” she said, before diving back down, taking you to the hilt.

You couldn’t hold back any longer, the pleasure building inside you until it was almost too much. “Sullin, I’m… I’m gonna come…”

She didn’t stop, her mouth working you over with a relentless intensity that drove you over the edge.

With a low groan, you came, your release spilling into her mouth. She moaned around you, swallowing every last drop.

As you came down from your high, she pulled back, a satisfied smirk on her face. “I told you,” she said, her voice thick with desire. “I can’t stop wanting you.”

Mending.

Pairing: Lucanis Dellamorte x Rook x Spite (gender-neutral) Genre: hurt/ comfort, protective Lucanis, protective Spite, Smitten Lucanis, Lucanis personal quest spoilers, Bisexual disaster Lucanis, first kisses, spite being spite, wingman spite, angst with a dash of fluff. Synopsis: in the aftermath of the fight with Illario, something doesn't go as expected. WC: 2k~ Ao3 link AN: is this me finally getting out of my writer's block again?

Lucanis’ eyes darted around the opera house, something was missing. So much had happened so quickly: the fight, deciding what to do with Illario, being announced as the new First Talon, that once he was handed the glass of celebratory wine and had a moment to think, he realized that he had lost sight of Rook.

He was so absorbed by this family drama that he didn’t ever realize when the room had been cleaned up from the bodies and guests started crowding the lower level of the theatre.

“Can’t believe. You lost Rook” Spite shook his head as he glanced around the room, pacing between the Crows and the guests, looking for the missing one.

He wanted to follow Spite so bad, abandon the glass of champagne and focus on Rook.

He was not quick enough though. One at a time the guests started approaching him. Some with compliments, and some already trying to get in his graces.

He hated every second of it. He wished Caterina had not pushed all this on him, had not forced him to take the mantle of First Talon, had not shoved on him all these expectations. He didn’t want to play the part.

He just wanted to look for Rook and leave.

Yet he had little choice, he just hoped Rook would find him, that the feeling that was harbored in his guts was just a fiction of his mind, one of the many attempts of his brain to let him cave in.

Minutes passed quickly, and of Rook there was no trace. He had prayed Rook would show up between the guests stopping him over and over again, looking for them in every interaction, in every greeting, in every congratulations. Of all the people crowding the room, the only one he wanted to see, it was Rook,

There was nothing to worry about, right? He thought as he followed the demon around the opera house with his eyes.

“Smells like blood” Spite walked past another small gathering of people, approaching one of the corners of the room and disappearing behind the throng.

Rationally he knew that it was normal for the opera theater to smell like blood. At the end of the day there had just been a bloody fight right there where a small horde of Venatori was taken down, but nothing stopped Lucanis from overthinking and wondering if the smell of blood belonged to Rook.

Dread filled his lungs as he excused himself, leaving one person after the other behind himself, following Spite’s taunting voice as he sniffed around. “Found Rook” The demon hummed as he stopped on his tracks and kneeled down. “Rook hurt” He hissed as he leaned forward, inching closer to their face.

They were sitting on the floor, their head lolling to the side as one arm was holding their abdomen tightly.

“Mierda” He swore under his breath as the view solidified in Lucanis’ eyes, the glass he was holding was quickly abandoned, shattered on the floor as he rushed by Rook’s side.

He could feel everyone’s disapproving gaze falling on him as he kneeled down, his composure down the drain as Caterina’s eyes burned holes in his back. “House Dellamorte never kneels” Her voice echoed in his brain, yet for once all he cared was beyond her opinion. All that mattered to him was Rook.

“Rook, you alright?” He murmured the futile question as he cupped their cheek, his palm gently turning their head towards them to take a better look. Blood was dripping down their nose, their eyes were half closed while their mouth hung slack, trying to catch their breath.

“Yeah” They mumbled under their breath, leaning in the touch carelessly. “Feeling dizzy” Their beautiful complexion was slowly drained of color, and yet even on the brink of exsanguination they were stunning.

“Gonna kill Illario” Spite hissed; he could feel the demon’s anger rising in his stomach and mixing with his own worry, a deadly concoction that was not going to bring anything good if Spite was not kept in check.

“Let’s get you out of here” He whispered as he sneaked his arms around Rook’s waist and brought them to his chest. He had to be quick, looking for a safe spot to mend whatever nasty wound Rook had and make sure they were okay.

The halls of Villa Dellamorte were home to him, so much that sneaking past the hidden corridors to his room was kid’s play, and there he was going to be unbothered, focusing on Rook only.

“You still with me, Rook?” He asked as he gently laid them on the softness of his bed, their head falling back against the pillows as he realized no answer was going to come from them any time soon. Shit. Shit. Shit.

“I’m sorry” Lucanis mumbled to himself as he quickly undid the buttons of Rook’s vest, discarding the ruined clothes to the floor and exposing the wound.

“Why are you apologizing.” Spite asked, his head tilting to the side as he stared at the scene unfolding in front of his eyes.

“I suppose you don’t understand” He held his breath as he carefully threaded the needle, battling with himself to keep his hands steady, something that should have been normal to him.

“Explain”

“I undressed them, without their knowledge. That’s..” He weighted the words on his tongue, hoping they’d make sense for the demon, ‘cause of all things, he was not going to sit there and overexplain himself when his.. lover could have been on the brink of death. “...Disrespectful”

“Disrespectful” Spite repeated, letting the word linger on his tongue as he stared at Lucanis carefully.

“Now if you’ll stay silent, I’ll patch them up” Lucanis turned resolute towards the demon, pointing the sharp needle his way and earning a groan and a nod.

“Be quick” He sat at the edge of the bed, next to Rook’s feet. “Miss Rook already” Spite mumbled as he crossed his arms, and for once, they were on the same page.

Lucanis was quick to focus again on Rook, his eyes tracing the countless scars on their exposed chest; he wanted to know their story, how Rook got them, how many they had to patch alone at the edge of consciousness, how many carried regret. He wanted to trace them with his lips as they got to learn about each other. He would have torn down walls for them, even if just for a moment.

Lucanis reached over for the folded towel, the gushing wound oozed so heavily that he wondered for a moment if Illario had pierced something vital.

He tried his best to steady his hands, pressing the cloth against the open skin to take away as much blood as possible before starting to stitch it up.

How long had Rook sat there bleeding out before being found? He wondered.

Why had they not asked for help? Question over question flooded his mind as he stopped just a moment to take a better look at Rook.

He expected to see some sort of reaction, to see their face contorted in a painful scowl, anything to remind himself that he was not going to lose them anytime soon, yet even while they were unconscious they tried their best to look calm.

It was something he admired about Rook. They always seemed in control even when things were slipping between their fingers. Even when the worst outcome was at their door, they always knew what to say. And yet, when they needed help, no one was there to see them, to notice the bloodstain growing on the fabric of their shirt.

What a fool Lucanis Dellamorte was for such oversight. Especially when he wanted to be around Rook all the time, when he wanted to pluck the stars from the sky for them, and when he wanted to protect them with every fiber of his being, despite the fear of uncovering the monsters hidden in his closet.

“Lucanis’ a sap” Spite rolled his eyes as he climbed completely on the bed, laying next to Rook. Lucanis hated sometimes how loudly Spite could read him. Even when he didn’t understand humanity, and when Lucanis couldn’t properly process his feelings, he was always asking those uncomfortable questions, leaving him questioning.

“I told you to-”

“Tell them” Spite stopped him before he could finish his sentence. “You want to. I don’t understand why you don’t”

“It’s..” He let out a groan as he looked down again, the wound already covered in blood once more. “Let me do this” Lucanis quickly dismissed Spite.

“I don’t get you” Spite shook his head, returning to his own thinking. He ghosted his hand over Rook’s itching to feel what Lucanis felt whenever his hand met with theirs, wondering if it would feel the same way. It was all futile wondering in the end.

The downsides of having a personal demon included hearing all their thoughts all the time, and he hated that his demon was just a mirror of his own feelings, so loud in his head it was impossible to drown him out.

The moon was shining high in the sky when Lucanis finally dropped the needle, a sigh of relief followed the clunk of hitting wood as he closed the little box and pushed it back under his nightstand and looked up at Rook.

He itched to touch them, to glide their fingers through their hair, to caress their cheek, to lean in and steal a kiss.

“Do it” Spite taunted.

“I’m not listening to you” Lucanis rebutted without a second thought.

Rook was still dazed, the sunlight shining through the blinds waking every nerve in their body as they adjusted to the unfamiliar environment.

The coffee aroma lingered in the air as they slowly opened their eyes. The last they remembered was gripping Lucanis' shirt and rushing through corridors.

Lucanis was near, sitting on a chair right next to the bed, one hand wrapped around Rook’s and the other holding a cup of coffee.

“What happened? Where are we?” Rook murmured, their voice still laced with the weight of sleep.

“I had to stitch you up” He smiled as he rested the cup on the nightstand and leaned forward. His free hand gently reached forward, cupping Rook’s cheek and caressing the soft skin. “I brought you to my room”

“Ah”

“How do you feel? Does the wound hurt?” He asked, leaving no time for Rook to think, his voice barely a whisper. He itched to lift the blanket, to ghost his fingers over their chest- and check the wound himself, obviously.

“I’ve seen better days” Rook slowly tried sitting up before being hit by a wave of pain, betraying his words right away.

Lucanis was quick, his arm was quickly wrapped around their waist. “Careful..” He cooed as he guided the other to sit up, trying his best to ease the pain of movement. He couldn't miss how Rook's cheeks ignited, their beautiful complexion shining with warmth at the small care.

“But thank you, if it wasn’t for you…” Rook resumed despite the itching pain, a soft smile spreading upon their lips.

They were so close as Lucanis still held his arm around their waist. Their warm breath mixing in the middle, as if to torture him, reminding him that they were just inches away from each other, so close yet so far.

“You should have told me Illario wounded you, you know?” His voice lowered as he sat at the edge of the bed, his arm not yielding from the new spot it occupied. He liked the way they felt in his arms.

“You found me, didn’t you?” Rook matched his tone, as if they were whispering secrets and the walls of Villa Dellamorte had ears to steal them away.

“Yeah”

Silence filled the room as Rook’s eyes fell on their intertwined fingers. Their heart leaping in their chest as they committed to memory the way his hand felt in theirs, the way his arm held them up protectively.

They felt safe, right there. Despite the wound on their abdomen, despite the world as they knew it about to fall apart.

“Kiss them. Kiss them” Spite chanted as they still laid near Rook, propping up only to meet his host’s eyes with a smirk plastered on his lips. Lucanis wanted to kiss them, to steal just one moment, but was it fair? Was it fair to selfishly graze their skin one more time and press their lips together just like that? Many times he had thought of it, daydreaming of the moment before his eyes, yet he had wanted their first kiss to be different.

He savored the idea on his lips, wondering if they'd taste as sweet as the words that came from their mouth. He wondered if they'd feel the same way he did.

One moment he was deep in his thoughts, and the following he couldn’t hold himself back. His lips gently crushed with Rook’s, and the stars he wanted to give them were around him; the universe he wanted to fight was in his palm.

He swore everything around him disappeared. Worries, thoughts, responsibilities. Vanquished.

There was just Lucanis and Rook and nothing else mattered.
