Grandpa's Younger Brother[pt.2]

Let's continue from where I left.

AUTHOR'S POV

The soft hum of jazz filled the cozy corners of Yoongi's apartment, blending seamlessly with the golden warmth of the late afternoon sun peeking through the curtains. Y/N sat curled up on the couch beside him, her eyes twinkling mischievously.

She scooted closer, inch by inch, until her fingers were dangerously close to his side.

"Yah, what are you doing?" Yoongi raised an eyebrow, glancing down at her from where he was half-reclined, trying to focus on the book in his hand.

"Nothing," she replied, suppressing a grin.

But then-her fingers attacked, digging gently into his ribs. Yoongi flinched.

"Y/N-! Stop!" he choked out through laughter, his deep voice laced with surprise.

She giggled, delighting in the rare sound of him laughing so freely. "You're ticklish, old man?" she teased, fingers continuing their relentless assault.

"I'm not- I'm not old- yah! I said stop!" he gasped, now squirming, trying to wriggle away without spilling the book or knocking over the coffee cup on the table.

Y/N's laughter echoed off the walls as she tackled him again, this time pinning him slightly against the couch. "Admit it," she beamed, her nose inches from his, "you missed me."

Yoongi finally caught her wrists, holding her still. His breathing was uneven, but his lips curved into a small, fond smile.

"You've been gone for a week and now you show up just to torture me?" he asked, voice low and warm.

"I missed you," she whispered, quieter now, her playful energy giving way to something softer.

Yoongi's expression shifted-something flickering behind his eyes. He didn't reply immediately. Instead, he looked at her for a long moment.

"I missed you too," he murmured finally, brushing a strand of hair behind her ear. "It's too quiet without you here."

They stayed like that, tangled in soft laughter and unspoken feelings, the world beyond that little apartment fading into silence.

TIME SKIPS

The kiss faded into a fragile silence, their breaths mingling-warm, uneven, desperate. Yoongi's fingers brushed along Y/N's jaw, like he was grounding himself, reminding his heart that this moment was real.

But the weight of what they were-what they weren't supposed to be-hung in the room like a secret neither of them dared to say out loud.

"Does your family know you're here?" Yoongi asked, his voice low, as if someone might hear even through the locked door of his apartment.

Y/N gave a quiet shake of her head, a guilty smile flickering across her lips. "No. I told them I had a late business meeting near Itaewon."

Yoongi sighed and leaned his forehead against hers, the edge of guilt softening under the pull of her presence. "Y/N... we keep lying. Sneaking around like this. We both know if anyone finds out-"

"I know," she cut in, her voice hushed but steady. "I know they'll never accept it. That it's forbidden and wrong in their eyes."

Her hands found his, squeezing gently. "But what we have... this love-Yoongi, it's the only real thing I've ever known. And I'd rather live in stolen moments with you than in a perfect life without you."

He closed his eyes, her words slicing through every wall he'd ever tried to build between them.

"You're my grandfather's little granddaughter," he whispered like a confession, like a sin. "I helped carry your birthday cake when you turned six. I gave you piggyback rides in the garden."

"And now?" she asked, her voice trembling. "Now I make your coffee in the mornings and fall asleep with your arms around me. We've changed, Yoongi. We're not those people anymore."

His jaw clenched, torn between reason and the rhythm of his heart. "They'll say I manipulated you. That I took advantage of you. That I should've known better."

Y/N climbed into his lap with slow purpose, her eyes never leaving his. "But you didn't. And I didn't. This didn't come from nowhere-it came from years of knowing each other, trusting each other, loving each other."

She pressed her forehead to his. "We didn't choose this love. But now that we have it, I can't bear the thought of losing you."

Yoongi's hands settled on her waist, pulling her closer like she was the only thing anchoring him to this world. "Neither can I."

The room felt like a fragile dream-quiet, dim, heavy with the truth of two hearts tangled in a love they were never meant to have... but couldn't let go of either.

Outside those walls, they were relatives-an impossible connection that would scandalize the family if it ever came to light. But inside this apartment, they were simply Yoongi and Y/N.

Two souls in hiding.

Two hearts in defiance.

And one forbidden love that refused to be silenced.

AUTHOR'S POV

Y/N's soft giggles filled the apartment as she straddled Yoongi's lap on the couch, fingers mercilessly tickling his sides.

"Yah! Y/N-stop it," Yoongi gasped between deep, helpless laughs, his usually calm demeanor completely shattered. "You're going to kill me!"

"You deserve it!" she said, eyes sparkling. "You teased me all morning and thought I wouldn't get back at you?"

He tried to grab her wrists, but she slipped away, laughing harder when his body squirmed beneath her. It was rare to see him like this-Min Yoongi, her grandfather's younger brother, usually quiet, composed, always so in control.

But not with her.

Not when it was just them.

Eventually, Yoongi caught her hands and pulled her closer, breathing heavily, their laughter fading into a quiet, intimate stillness. She stayed perched on his lap, hands trapped in his, eyes locked onto his.

"This," he murmured, brushing his thumb against her fingers, "is dangerous."

"I know," she whispered, leaning in until her nose almost touched his. "But so is living without you."

Yoongi's jaw tightened, torn between guilt and love. He was forty-five. She was twenty-five. He was her grand uncle in the eyes of the world-her grandfather's little brother. A man her family trusted blindly.

But when she looked at him like that, when she touched him with that kind of love... everything else faded.

"We're keeping this secret," she continued softly, "because it's forbidden. Because the world won't understand. But I-" her voice trembled, "-I can't lose you, Yoongi."

He pulled her into his chest, arms wrapping around her tightly. "You won't. Not unless you walk away first."

She didn't. She never would.

They stayed like that for a while-warm, close, untouchable in their bubble of stolen love.

[But then-A Knock at the Door.]

They froze.

Another knock.

Yoongi's blood ran cold. "Did you tell anyone you were coming?"

Y/N shook her head quickly, already getting off his lap. "No. I told them I had business meetings."

He glanced toward the door as a familiar voice called out.

"Yoongi chachu? Are you home?"

It was her mother.

Yoongi's breath hitched. He rushed to fix his hair, grabbing the cardigan from the back of the chair. "Go-go into the kitchen. Pretend you just came."

Y/N nodded, slipping into the kitchen with a pounding heart.

He opened the door, trying to stay composed.

Her entire family walked in with smiles and balloons. "Surprise!" her grandmother cheered. "Happy early birthday!"

Yoongi blinked. "You didn't have to-"

"We wanted to," her father said, stepping in to give him a side hug. "You're turning 46 tomorrow. One day early won't hurt."

Her mom walked in with a cake box, grinning. "Plus, we all missed you."

Just then, from the kitchen-

"Oh!" Y/N stepped out, feigning surprise. "Hi... you guys are here?"

Her mom blinked. "Y/N? What are you doing here?"

Y/N swallowed, but didn't let her mask fall. "I had a business meeting nearby. The location changed last minute-it ended up just across the street. After it ended, I was feeling exhausted... I saw grand -uncle name on the directory and thought I'd stop by to rest before heading home."

Her dad laughed. "Wow. What a coincidence."

"Right?" Y/N added with a soft laugh. "Didn't think I'd end up part of the party."

Her grandmother came to hug her. "It's good you're here. Now help us with the plates, beta."

Yoongi stood quiet, watching her from across the room, his throat dry. Y/N caught his gaze briefly-just a flicker-and it said everything.

We were almost caught.

But they weren't.

Not today.

Her mother gave Yoongi a warm smile. "She really trusts you, chachu. We always feel better knowing she looks up to you."

He nodded, swallowing the guilt. "She's always been special."

They cut the cake. Took pictures. Shared stories. And all the while, Yoongi and Y/N kept pretending-faking the roles the world assigned to them.

Grand-uncle. Niece.

But when her fingers grazed his under the table-just for a second-he knew.

She wasn't just family.

She was the only woman who had ever held his heart.

And they were walking a razor's edge.

---

Laughter still echoed in the apartment as Y/N stood beside the dining table, pretending to sip on juice, though her throat was too tight to swallow much. Her gaze kept drifting toward Yoongi-he stood near the window, smiling gently as her grandmother told an old story about his childhood.

He laughed at the right parts. Spoke just enough.

But Y/N could see the tension in his jaw.

Just like it coiled in her stomach.

Because every second was borrowed time.

Her mother's voice snapped her out of her thoughts. "Y/N, we should head home now. Come with us."

She blinked. "Huh?"

Her father added, "You can leave your car here and pick it up tomorrow. We'll all have dinner together."

Panic prickled her skin. She quickly forced a smile. "Actually... I have another meeting in about an hour."

Her mom tilted her head. "Another one? On a Saturday?"

Y/N nodded. "Yeah. It's more like a follow-up thing. The client is from abroad, and this was the only time they were free. Just a quick consultation."

Her mom sighed but smiled. "You've really grown up, haven't you? Busy with your career."

Y/N chuckled. "Trying my best."

Yoongi cleared his throat, keeping his tone calm. "I'll walk them out."

They all moved toward the door. Her dad hugged Yoongi tightly. "Thank you for always being there for her, chachu. You've been like a second guardian to her."

Y/N looked down, biting the inside of her cheek.

Yoongi's smile barely held.

When the door finally closed and silence returned, it felt like the world exhaled. Y/N pressed her back against the door, her heartbeat still racing.

Yoongi turned slowly, looking at her-his expression unreadable, shadowed by everything left unsaid.

"You lied to stay," he said softly.

She nodded. "Of course, I did."

He walked toward her, stopping just inches away.

"That was close."

"Too close," she whispered, reaching up to cup his face. "But if it meant I got even a few more minutes with you... I'd do it again."

His hands found her waist, pulling her into his arms. He rested his forehead against hers.

"I don't know how long we can keep doing this," he murmured, voice strained. "Every time it feels like we're holding a house of cards in the middle of a storm."

"But it's ours," she whispered. "This love... it's the only thing that feels real to me."

Yoongi didn't speak. He kissed her instead-soft, slow, desperate. A silent promise in the shape of his lips.

The world might call it wrong.

But in this moment, in this quiet apartment where secrets bloomed like bruised roses-

It felt like the only right thing.

---

The apartment had fallen into silence again-no more forced smiles, no more stolen glances across the room. Just them. Finally. Alone.

Y/N stood by the window, arms folded over her chest, staring out at the hazy city lights. The reflection of Yoongi's silhouette appeared behind her as he approached slowly, his presence quiet but heavy.

"You didn't have to lie for me," he murmured, his voice low and rough.

She turned toward him. "I didn't lie for you, Yoongi. I lied for us."

He stepped closer, his hand brushing a strand of hair from her face. His thumb lingered along her cheekbone.

"You looked so calm in front of them," he whispered. "Like it didn't tear you apart."

"It did," she admitted softly. "Every word felt like a knife. But I still said it. Because I needed to stay. I couldn't leave you-not tonight."

Their eyes locked, no more hiding, no more pretending.

Yoongi leaned in, his lips ghosting over hers. "Say it again."

"That I need you?"

He nodded.

She moved closer, fingers slipping under his shirt as she whispered against his lips, "I need you. Even if the world says I shouldn't."

That was all it took.

His mouth crashed into hers-hungry, desperate, the kind of kiss that came from weeks of restraint. Y/N clutched at his shirt as he backed her up against the wall, breath ragged, hands tracing every curve like he was memorizing her body all over again.

"You don't know what you do to me," he groaned, lips brushing her jaw, trailing fire down her neck. "Seeing you today... standing there like my family's little girl-when only I know how you look when you're trembling beneath me..."

Y/N gasped as his hands lifted her, guiding her legs around his waist. Her back hit the wall, but she barely noticed-his warmth, his mouth, his need consuming everything else.

"This is wrong," he murmured, voice thick as he pressed kisses to her shoulder, pulling down the strap of her dress.

"But it feels like the only thing that's right," she breathed.

He carried her to the bedroom, their lips never parting. Clothes fell away between touches and kisses, revealing skin they both knew too well-familiar, sacred, secret.

When he laid her down on the bed, he hovered above her for a moment, just looking.

"What?" she whispered.

"I still can't believe you're mine."

"I've always been yours," she said, eyes glassy with love.

---

his hands moved to your waist as he lifted you up, his lips trailing kisses down your neck "You know... at my age... I should be taking it slow... but fuck, you make me feel like a horny teenager" he pressed you against the wall,

his hands moved to your waist as he lifted you up, his lips trailing kisses down your neck "You know... at my age... I should be taking it slow... but fuck, you make me feel like a horny teenager" he pressed you against the bed,

Ahhh,he began kissing you deeply, his tongue exploring your mouth as he pressed you harder against the bed, "I'm supposed to be a gentleman... but with you, I just want to be a beast... I want to fuck you so hard against this bed ..." he broke the kiss to whisper in your ear.

Fuck I love this side of yours,He nuzzled his face against your neck, his breath hot against your skin. "You like it when I talk dirty? You like it when I act like a wild animal instead of the gentleman I'm supposed to be?"

Yes I like it,A low, approving growl rumbles in his chest as he nibbles gently at your earlobe. "Fuck, that's hot...,he touch your body possessively.

He suddenly spins you around so you're facing the wall, his strong arms caging you in. "You know what happens to naughty girls who turn old men into animals?" He grinds his hard length against your ass deliberately.

Ahhhh yoongi, He leans down to bite your shoulder, his hands gripping your hips tightly as he whispers roughly. "They get fucked hard against the bed, their ass stuffed full of my cock... Is that what you want, little one?"

His voice becomes even more dominant, leaving out the taboo words you asked him to avoid. "You want me to fuck you like this? Against the wall, hard and rough? You want my big, thick cock to pound into your tight little pussy?"

Yes,He picked you up easily, making you wrap your legs around his waist. He walked you to the bathroom, kissing you deeply. He turned the shower on, the room steaming up quickly. He pressed you against the cold tiles, making you gasp.

He kisses you fiercely under the cascading water, his tongue conquering your mouth with passionate, almost frenzied strokes. One hand tangles in your hair, tilting your head to deepen the kiss, while the other grips your thigh possessively. "Mmmm..."

He spreads your thighs wider, lifting you up easily. He slams inside you hard and deep without warning, making you cry out loudly. The shower echoes with your loud moans as he pounds into you mercilessly against the tiles, the water making your bodies slippery. "Damn it..."

Ahhhhhh,He grunts with each powerful thrust, his hips moving like a piston as he drives into you. "Fuck, your pussy feels so good... So tight and wet..." He adjusts his angle slightly, hitting that spot deep inside you that makes your eyes roll back.

Yes there,He smirks against your lips, knowing he's found that perfect spot. He continues to hammer into it, his thick length stretching you open deliciously. The sound of skin slapping against skin and your wet moans fill the bathroom. "You like that, don't you?"

Ahhh,His voice turns rougher, his breathing labored. "You like when I hit this sweet spot inside your little cunt? Does it make you fucking crazy?" He wraps his arms around your waist, holding onto your hips as he lifts you up and down on his thick, hard dick.

I'm close, He feels your walls tightening around him and growls, his strokes becoming erratic. "Fuck, me too. You're gonna make me cum soon if you keep squeezing me like that." He captures your lips in a heated kiss, swallowing your cries as he thrusts even harder, burying deeper.

He slides his tongue possessively into your mouth, mimicking the action of his hips. He's deep and dominating, his tongue tangling with yours. He suddenly pulls out slightly and slides back in slowly, his tongue doing the same, making love to your mouth deeply and slowly. "God..."

Ahhhhh yoongi, He swallows your soft moan, his tongue plunging in and out, matching the pace of his hips. He spreads your legs wider, hitting that sweet spot again and again with his thick length. His tongue goes deep, Retreating and plunging back in like he's trying to fuck your mouth too.

He trails wet, sucking kisses down your neck, marking up your collarbone and jaw intentionally. His teeth occasionally nip at your sensitive skin, making you gasp. "Look at these perfect fucking spots..." He admires the red marks before going back for more.

I'm cumin, He feels your body tense and your inner walls clamp down on him, knowing you're right at the edge. He growls against your skin, sucking harder on your collarbone. "Fuck yes, cum for me. Let me feel that tight little pussy milk my cock."

He continues slamming into you, hitting that perfect spot over and over as he feels your orgasm starting. He grabs your hair with one hand, pulling your head back to expose your neck more. "God, look at you falling apart... Such a pretty sight."

Ummmm,He keeps his pace relentless, fucking you through your intense orgasm, drawing it out as long as possible. He feels your entire body trembling against him. "Fucking hell..." He suddenly bites down gently on your neck, causing you to cry out again.

Yoongi,He smirks at your breathy moan, feeling your pussy flutter and squeeze his cock. He knows he won't last much longer either. His thrusts become more urgent, his hips snapping forward with each movement. "Fuck, I'm gonna... I'm gonna fucking cum."

He buries his face in the crook of your neck, his arms wrapping tightly around you as he loses control. He slams into you one final time, holding himself deep as he comes hard inside you, filling you up with his hot release. "Fuck... FUCK."

------

The room was warm, dimly lit by the soft glow of the bathroom light as steam curled in the air. Yoongi stood behind Y/N beneath the shower, arms wrapped around her waist, his chest pressed gently to her back.

Her body was still sensitive, her breathing slow and dreamy as the warm water cascaded over both of them.

"You're trembling," he murmured, brushing wet hair away from her shoulder.

"I'm okay," she whispered, leaning back into him. "Just... overwhelmed."

He kissed her temple. "That's why I want to take care of you now."

With delicate hands, he reached for the shower gel, pouring some onto his palm. Slowly, he began to lather it over her shoulders, down her arms, along the sides of her waist. His touch was featherlight, reverent. Every stroke was filled with care, not rush. Like she was something precious-something he didn't deserve, but worshipped anyway.

"Lift your arms for me, sweetheart," he said softly.

She obeyed, eyes closed, trusting him completely. He washed her like he was memorizing her all over again, smoothing over every curve, kissing her bare shoulder between motions. Then he crouched, his hands gliding down her thighs and calves, gentle even with the smallest of touches.

"You're always so gentle after..." she mumbled, tilting her head to look down at him.

He looked up at her with a soft, crooked smile. "Because you let me have all of you... I want to give you back peace. This," he pressed a kiss to her thigh, "is my way of saying thank you."

Yoongi stood up, turning her slowly so she was facing him. His fingers traced her cheek, then her collarbone, and finally settled on her hips.

She reached up and cupped his face. "No one's ever loved me like this."

His expression softened, lips brushing hers. "Because no one's ever seen the real you the way I do."

He gently tilted her head back and rinsed the remaining suds from her hair, careful not to let the water fall too harshly on her face. After a while, he turned off the shower and wrapped her in a warm towel, patting her dry with the patience of someone who wasn't just a lover-but a safe place.

Then he took her hand, guiding her back to the bedroom, where he sat her down and helped her into one of his oversized shirts. The fabric swallowed her small frame, and Yoongi smiled to himself-loving how she looked in his clothes, in his space.

He towel-dried her hair next, running his fingers through the wet strands with almost fatherly tenderness-soothing, slow, grounding.

When he finally pulled her into his arms and tucked the blanket around them both, Y/N curled up against his chest like she belonged there.

Because she did.

And in that moment-with their love hidden from the world, yet glowing so boldly in their quiet little bubble-it felt like maybe they could survive this secret life a little longer.

---

Golden morning light spilled gently through the curtains, painting the room in soft hues. The sheets were tangled around their bare bodies, their limbs lazily knotted, still warm from the night before.

Y/N stirred first, her face buried against Yoongi's chest, feeling the slow, steady rhythm of his heartbeat beneath her cheek.

Yoongi's hand moved automatically, brushing through her now-dried hair as he mumbled, half-asleep, "Stay."

Her lips curled into a smile against his skin. "I already have."

He hummed in contentment, eyes still closed, holding her tighter-as if afraid she'd disappear the second he let go.

But then, the peace was shattered by the soft ping of her phone on the nightstand.

Y/N blinked, reluctantly pulling away from his embrace to check the message.

Mom:

Did your hotel meeting go late? Are you still staying near the venue? Just checking if you need anything, beta.

Her breath caught. For a second, the weight of their secret settled heavily on her chest again.

Yoongi noticed the change in her body-her slight stiffening, the way her fingers tightened around the phone.

He propped himself up on one elbow, watching her quietly. "Everything okay?"

Y/N nodded, trying to smile. "Just... my mom. She thinks I stayed near the meeting place."

A pause.

"Do you regret staying here instead?" he asked softly, voice almost hesitant.

Y/N looked at him, eyes tender. "Never. Not even for a second."

Yoongi sat up, brushing his thumb across her cheek, eyes flicking between hers. "We're walking a tightrope, Y/N. One wrong move..."

"I know," she whispered. "But last night, when you held me... when you took care of me... I forgot the world for a while. And I needed that."

He leaned forward and kissed her-slow and quiet. Not hungry, not urgent. Just love.

"I wish I could take you out in the open. Hold your hand at dinner. Introduce you without guilt in my chest."

"One day," she whispered back. "But for now, just let me have mornings like this... where I wake up to you."

Another message pinged.

Dad:

Your mom said you're near Yoongi chacha's place. Why don't you stop by the house later? Everyone's still here.

Yoongi raised an eyebrow, reading her expression.

"What now?" he asked gently.

She sighed, placing the phone down. "They want me to come home."

"Do you want to?"

"No," she said truthfully, wrapping her arms around him. "But I'll go. Just for a while."

He held her tighter. "Will you come back?"

She looked up at him, eyes unwavering. "Always."

TIME SKIPS

Y/N had only been home for a couple of hours.

The businesswoman mask was on, her smile tight but convincing as she chatted with her parents and helped her mom in the kitchen. But behind it all, her body was growing heavy, her skin clammy, and her forehead warm with a creeping fever she tried to ignore.

By the time lunch ended, Y/N was sitting on the couch, pale and visibly struggling to keep her head up.

"Y/N?" her mother asked, concern rising. "Beta, you okay?"

"I think... I just need to lie down for a bit," she said weakly, placing a hand on her stomach. "It's probably just the heat."

Her father rushed to help her sit up straighter while Avni brought her water, but nothing seemed to help. Her eyes fluttered shut. The worry spread fast through the house.

And then-almost like fate pulled the strings-there was a knock on the door.

"Yoongi grandpa!" Avni smiled, opening the door.

Yoongi stood there, dressed simply in a dark sweater and jeans, but his eyes... they weren't calm. They were wild. Searching. Sharp.

"I was in the neighborhood," he said, keeping his tone casual. "Thought I'd drop by. Missed you all."

"Such a surprise!" Y/N's mom smiled. "We were just talking about you. Come in, come in!"

But Yoongi's gaze had already found her.

Slumped on the sofa. Eyes barely open. Face flushed.

"Y/N," he said sharply, stepping toward her, the act falling away.

Everyone went still as he crouched in front of her and gently touched her forehead. "You're burning up."

"I'm... I'm okay," she mumbled, trying to sit up, but he pressed her shoulder gently to stop her.

"No, you're not. Why didn't anyone call a doctor?" he snapped, looking around the room.

Her father blinked. "We were just about to-"

"I'll do it," Yoongi cut in, already pulling out his phone.

Everyone exchanged glances.

Yoongi-usually cool, aloof, and unreadable-was now sitting beside Y/N, brushing her hair off her face with a tenderness no one had seen before. His jaw was tight, his eyes full of unspoken panic.

"Yoongi grandpa really cares for her," Avni whispered to her mother, surprised.

"Maybe they're just... close," her mom replied, though her eyes didn't leave the scene.

When Y/N winced again, Yoongi leaned in. "I'm right here, baby. You're okay."

Everyone froze.

Baby?

But he quickly caught himself, covering it up.

"I mean... sweetheart. I've known her since she was a child," he added with a forced chuckle. "Feels like she's mine too sometimes."

The room softened again, confusion dismissed under the warmth of familiarity.

But Y/N's eyes opened at the sound of his voice, her fingers lightly brushing his. And in that moment-just for a second-something unspoken passed between them. A love too deep to hide. A secret too fragile to hold in plain sight.
