Dirty uncle koo

"Tae, baby, wake up. You have school, petal."

Taehyung heard Jungkook's voice through his sleep.

He whined and pulled the blanket over his head.

"No school... please," Tae mumbled.

Jungkook sighed.

The next second, Taehyung felt himself being lifted-blanket and all.

"Yah!" Tae protested.

Jungkook carried him easily and sat down on the bed, placing Taehyung on his lap, still wrapped in the duvet.

"Your mom and dad will scold me until my ears bleed," Jungkook said.

"So no skipping."

Taehyung slowly peeked out of the blanket.

He made the angriest pout he could. His cheeks puffed, lips pushed out.

"Unfair," he muttered.

Then his expression changed.

"Uncle..." Tae said softly.

"Please."

He moved closer, rubbing his nose against Jungkook's cheek.

"No school, hmm?" Tae continued sweetly.

"My handsome Uncle Koo."

"My sweetheart Uncle Koo."

"My baby Uncle Koo."

He kissed Jungkook's cheek again. And again.

"That always works," Tae added confidently.

Jungkook closed his eyes and sighed deeply.

"Why are you like this?" he muttered.

He gently dropped Taehyung back onto the bed.

"Fine," Jungkook said. "One day."

Taehyung's face lit up instantly.

"Yes!" He clapped his hands happily, bouncing on the bed.

Then he stretched his arms toward Jungkook.

"Carry me," he demanded.

"No," Jungkook replied calmly.

He turned and walked toward the cupboard to grab a towel and clothes. He had just come back from the gym, shirtless, only wearing shorts, sweat still on his skin.

"I need a bath."

Taehyung stood on the bed and jumped lightly.

"Uncle, carry me," he whined.

"Stop acting like a baby," Jungkook said without turning around.

"You're grown up."

Taehyung gasped dramatically.

"I'm a baby," he argued.

"I'm your baby."

He pointed at Jungkook.

"So carry me. Now."

Jungkook paused.

He looked back.

Taehyung was standing there, hair messy, wearing Jungkook's oversized hoodie, arms still stretched out, pouting like the world would end if Jungkook didn't listen.

Jungkook stared for a long second.

"...You're impossible," he said.

But he walked back anyway.

And Taehyung smiled, knowing-

He always would.

As Jungkook carried Taehyung toward the bathroom, Tae leaned his head against Jungkook's shoulder.

"Uncle Koo..." Tae said quietly.

"How can I get a body like you, hmm? All muscles... hard."

Jungkook paused for half a second but kept walking.

"You are good as you are," he said firmly.

"No need to change."

Taehyung frowned.

"No," he protested softly.

"Everyone in school laughs at me."

Jungkook stopped in front of the sink.

"For my weight," Tae continued, voice shaky.

"No clothes fit me properly. I look like a potato in everything."

"And these pimples..."

He touched his cheek sadly.

"Tell me how," Tae whined. "Please."

Jungkook sighed.

He lifted Taehyung and placed him gently on the bathroom counter.

"Look at me," Jungkook said.

Taehyung looked up.

"You don't need to be like me," Jungkook said calmly.

"But if you want to feel better, we can try small things."

He picked up the toothbrush and put toothpaste on it.

"How about exercising a little?" Jungkook suggested.

"And eating fewer sweets."

He gently pulled Taehyung's lips down.

"Especially these," Jungkook added.

"They give you cavities."

Taehyung tried to pull away.

"Hey-!"

Jungkook leaned closer, inspecting his teeth.

"Yah," Jungkook said.

"Why are they yellow?"

He lightly bumped Taehyung's forehead with his own.

"Brush properly."

Taehyung pouted.

"You're mean."

Jungkook smiled faintly.

"Open," he ordered.

Taehyung opened his mouth.

Jungkook started brushing his teeth carefully, slow and gentle, like he had done so many times before.

"Uncle," Tae mumbled around the brush.

"If I become handsome... will people stop laughing?"

Jungkook froze for a second.

Then he continued brushing, slower this time.

"They laugh because they're stupid," Jungkook said quietly.

"Not because of you."

Taehyung's eyes softened.

Jungkook rinsed the brush and wiped Tae's mouth with a towel.

"You're already enough," he added.

"Remember that."

Taehyung sat on the counter, legs swinging, arms wrapped around Jungkook's neck.

"When I become pretty," he said dreamily,

"I'm going to marry a handsome and rich man."

Jungkook paused.

Taehyung smiled wider, eyes shining.

"You'll hold my hand and walk me to the wedding stage," he continued.

"I'll wear a red dress. My husband will wear white. The whole hall will be red and white."

Jungkook lifted him into his arms, holding him close, listening without interrupting.

"Then I'll have five kids," Taehyung added seriously.

"Happy married life. The end."

Jungkook looked down at him.

"...The end?" he asked.

He carried Taehyung toward the bathroom and set him gently on the edge of the bathtub as he turned on the tap. Warm water slowly filled the tub.

"What about your studies?" Jungkook asked quietly.

"Your job? Your dreams?"

Taehyung shrugged, completely unbothered.

"I told you," he said.

"I'll marry a rich man. He'll work for both of us."

Jungkook sat beside the tub, watching him.

"And my dream?" Taehyung continued.

"My dream is to be rich without working."

He leaned closer and hugged Jungkook again.

"So, Uncle," Taehyung said softly,

"help me become pretty. Help me become beautiful."

Jungkook reached out and gently pinched his cheek.

"Ani," he said firmly.

"You're fine the way you are."

Taehyung frowned.

"No," Jungkook added, pressing his thumb into Taehyung's soft cheek,

"you're perfect like this, my potato."

Taehyung gasped.

"I am not a potato!"

Jungkook smiled faintly and kissed Taehyung's chin.

"Do you even know how five kids are made?" Jungkook asked.

Taehyung looked at him, confused for a second, then nodded.

"Of course I know," he said confidently.

Jungkook waited.

"After marriage, God sends them," Taehyung explained.

"You just pray and tell Him how many you want. Umma said so."

Jungkook slowly turned his face away.

"...Aish," he muttered.

Taehyung frowned. "What?"

"Nothing," Jungkook said, rubbing his neck.

"Just-nothing."

Taehyung had grown up in a strict house.

Seokjin was soft. He smiled often, cooked for Taehyung, hugged him when Namjoon wasn't looking.

But Namjoon was different.

Always watching.

Always checking.

What Taehyung wore.

How long his sleeves were.

Whether his shirt was loose enough.

Namjoon chose Taehyung's clothes every morning.

Old-fashioned colors. Baggy fits. Nothing that stood out.

Even Taehyung's phone wasn't really his.

A small button phone. Only calls. No internet.

Namjoon said smartphones ruined children.

At home, there was no Wi-Fi.

No laptop.

No tablet.

Only an old television that played vintage dramas and news.

At school, it was easy to notice.

Everyone else scrolled, laughed, shared videos.

Taehyung sat quietly, holding his bag, pretending he didn't hear the jokes.

"Is that even a phone?"

"My grandmother has one like that."

Sometimes they tried to take it from him.

Sometimes they laughed at his clothes.

Taehyung never fought back.

He didn't know how.

He only knew how to smile and pretend it didn't hurt.

That was why he believed what his mother told him.

That was why he still thought kisses were just affection.

Jungkook watched Taehyung carefully.

"What will happen to you, bubba?" Jungkook said, his voice soft. "The world is going to swallow you whole."

"What do you mean, swallow?" Taehyung asked, confused. "I'm not food."

Jungkook laughed. "Yes, you are. Let me eat you!" he said, tickling him.

He pushed Taehyung gently into the bathtub. Jungkook got on top of him, settling carefully in the water. As he moved Taehyung to a more comfortable position against the tub, he asked, "Do you remember what I taught you yesterday, about kissing?"

Taehyung nodded, his eyes big.

"How do grown-ups kiss?" Jungkook asked.

Taehyung leaned forward and clumsily pressed his lips against Jungkook's. "Like this?" he mumbled against his mouth.

Jungkook chuckled. He gently took Taehyung's chin in his hand. "No, not like that," he said, then pushed his tongue between Taehyung's lips. "Open wide," he commanded.

Taehyung, surprised and not knowing what else to do, opened his mouth wide, letting Jungkook in.

"You like kissing?" Jungkook asked, his voice a low murmur against Taehyung's lips.

Taehyung nodded quickly, his eyes still closed, trying to process the strange new feeling.

"Good," Jungkook whispered, his thumb stroking Taehyung's cheek. "But you can't let anyone know we kiss like this, hmm? You remember our secret. Uncle is going to teach Tae about how to become a grown-up."

Taehyung's eyes fluttered open. A secret. Just for him and Uncle Koo. He nodded again, this time more seriously. A grown-up. He wanted that. He wanted to stop being a potato.

"Good boy," Jungkook praised.

Then he leaned in and claimed Taehyung's mouth again. This kiss was different. It wasn't a lesson. It was hungry. Jungkook's mouth moved against his with a desperate urgency, his tongue thrusting deep, exploring every corner of his mouth. Taehyung was overwhelmed, his body pliant and soft under Jungkook's hard frame. He didn't know what to do, so he just held on, his fingers digging into Jungkook's wet shoulders.

Jungkook's hands were everywhere. One tangled in Taehyung's damp hair, holding his head in place. The other slid down his back, under the soaked hoodie, his rough palm gliding over Taehyung's smooth skin. He gripped Taehyung's hip, pulling him closer until there was no space left between them. The water sloshed over the sides of the tub, forgotten.

Taehyung felt a strange pressure against his thig°h, something h°ard and insistent pressing through Jungkook's shorts. It made his stomach feel funny, all tight and hot. He made a small, questioning sound into Jungkook's mouth, but Jungkook just groaned and kissed him harder, like he was trying to devour him.

Jungkook's lips left his mouth, trailing a wet, hot path down his chin and neck. He bit gently at the sensitive skin where Taehyung's neck met his shoulder, and Taehyung cried out, his back arching. It hurt, but it also sent a jolt of pleasure straight to his core.

"Uncle...?" he gasped, his voice shaky.

"Shhh," Jungkook soothed, his lips moving back up to Taehyung's ear. "Just feel, Tae. This is part of growing up."

He pulled back slightly, his dark eyes burning with an intensity that scared and excited Taehyung. With one hand, he tugged at the hem of the soaked hoodie Taehyung was wearing.

"Let's get this off," Jungkook said, his voice thick. "It's all wet."

Tae's hands flew down, pressing against Jungkook's wrist, stopping him from pulling the hoodie any further. "Uncle, no," he said, his voice small but firm. "You can't."

Jungkook stilled, his hovering over the wet fabric. A flicker of frustration crossed his face before he smoothed it over with a gentle, questioning look. "Why, baby?" he asked softly. "It's just wet. We need to get you clean."

Taehyung shook his head, his cheeks flushing a bright red that had nothing to do with the warm water. He looked down at the water, at his own reflection distorted in the ripples. "Because... because it's bad," he whispered.

Jungkook raised an eyebrow, a hint of a smile playing on his lips. "Bad? What's bad about it? It's just taking off your clothes for a bath."

Taehyung squirmed, uncomfortable. He looked back up at Jungkook, his eyes wide with genuine innocence. "Umma and Appa said... they said only a husband can see his wife without clothes. And we're not married," he explained, his logic simple and absolute. "So... it's bad. We can't."

"Oh, my sweet, innocent Tae," he murmured, his thumb stroking the blushing skin. "That's a rule for other people. Not for us."

Taehyung frowned, confused. "But..."

"Uncle is teaching you, remember?" Jungkook interrupted, his voice smooth and persuasive. "This is a special lesson. It's our secret. Husbands and wives do this, yes, but uncles who are teaching their special Tae how to be a grown-up do it too. It's a different rule. A secret rule just for us."

He leaned in close, his lips brushing against Taehyung's ear. "It's only bad if you get caught," he whispered. "And we're not going to get caught, are we? This is our secret."

Before Taehyung could protest again, Jungkook's hands were on the hem of the hoodie. "It's okay, baby," he murmured, his voice a low, hypnotic rumble. "Uncle's just looking. Just for our lesson." He peeled the wet fabric up and over Taehyung's head, tossing it aside with a wet slap on the tiled floor.

The air hit Taehyung's bare torso, and he instinctively tried to curl in on himself, his arms coming up to cover his chest. But Jungkook caught them, stilling him.

For the first time, Jungkook truly looked at him. His gaze was intense, heavy, sweeping over Taehyung's body with an unnerving focus. Taehyung suddenly felt more naked than he ever had in his life. He was all grown up now, but not in the way he'd dreamed. His chest had developed faster than other boys, the soft flesh spilling over the simple cotton bralette he wore. It was too much, too big, and he hated it. His stomach was soft and round, a perfect, pudgy curve over the water's surface.

Jungkook didn't say anything. He simply reached out, taking Taehyung's hand and lifting it, inspecting it as if it were a curious artifact. Then his eyes moved to the space beneath Taehyung's arm, where the skin was exposed. There, a small, dark patch of hair had grown. Jungkook's thumb moved, tracing the coarse strands gently.

Taehyung flinched, a wave of mortification washing over him. This was so awkward. This was private. He tried to yank his arm down, to hide himself, but Jungkook's grip was firm. He felt ugly. He felt wrong.

He knew that in cities, people wore revealing clothes. His uncle had traveled the world for concerts, gone to hotels and beaches where people walked around in just their bras and underwear. Taehyung had seen pictures in old magazines his father had thrown away. Those people were beautiful. Their bodies were toned and flat, their skin smooth and perfect. They were pretty.

And his uncle must have seen them too. Of course, he had. How could he not compare them to... this? To Taehyung's soft, fat stomach and his too-large chest and the embarrassing hair under his arms? They were pretty and beautiful, while he was just... fat and ugly. He could feel tears prickling at the corners of his eyes.

**

"Uncle..." he whispered, his voice trembling. "Don't look."

Jungkook finally released his arm, his eyes meeting Taehyung's. There was no disgust there, no mockery. Just a deep, unreadable hunger. "Why not?" he asked, his voice thick. "You're beautiful."

The lie was so blatant it hurt. Taehyung shook his head, a tear escaping and sliding down his cheek. "No, I'm not."

"Yes," Jungkook insisted, leaning forward. He cupped Taehyung's face, his thumb wiping away the tear. "You are. You're perfect." He then lowered his head and pressed a soft, warm kiss right on Taehyung's stomach, just above his navel.

Taehyung gasped, his body jolting at the unexpected, gentle contact.

Tears continued to well in Taehyung's eyes, blurring Jungkook's face into a mess of shadows and light. He was so sure of his ugliness, so convinced that Jungkook was just being kind.

But Jungkook just shook his head, his expression full of a tenderness that made Taehyung's chest ache. "Tae, you are such a pretty omega," he said, his voice dropping to a husky whisper. "Why so insecure, baby? Each part of you is beautiful."

He leaned in and captured Taehyung's lips in a soft, lingering kiss. It was gentle, a stark contrast to the hungry ones from before. "From these lips," he murmured against them.

Then his mouth began a slow, deliberate journey. He kissed the corner of Taehyung's jaw, then down his throat. He paused where the neck and shoulder met, pressing a hot, open-mouthed kiss to the sensitive skin. "From here," he breathed.

Taehyung shivered, his body trembling under the assault of gentle affection. This was worse than the hungry kisses. This was breaking down every wall he'd ever built around his self-loathing.

Jungkook lifted Taehyung's arm again, not inspecting this time, but guiding it upward. Taehyung froze, expecting ridicule, but all he received was a soft kiss placed directly on the dark hair under his arm. Jungkook's lips brushed against the coarse strands, a gesture so intimate and accepting it stole his breath.

"To this," he said, his voice vibrating against Taehyung's skin. He lowered Taehyung's arm and looked him straight in the eye, his gaze burning with an intensity that pinned him in place. "Everything in you is pretty, Tae."

Jungkook's hands moved to his back once more, his fingers finding the clasp of the bralette with practiced ease. This time, Taehyung didn't protest. He was too stunned, too overwhelmed by the sheer conviction in Jungkook's voice. With a soft click, the bra was undone. Jungkook slowly slid the straps down Taehyung's arms, peeling the wet fabric away and letting it sink into the water.

He looked at Taehyung's now-bare chest, the large, soft mounds of flesh with their dusky nipples, and he let out a low, appreciative groan. "Especially these," he murmured, before dipping his head down to take one peaked nip°ple into his mouth.
