*****

Loud voices of talks and laughter filled the beach house. Taehyung walked down the stairs, showered and well rested but people's enthusiasm for his birthday didn't annoy him today. He walked down the stairs; each step gave him a faint reminder of last night.

He looked around the place searching for Jungkook.

"Hey Taehyung!" Jimin called him grabbing his attention. "Uncle Jungkook is asking what flavor you want." He pointed towards his phone. Taehyung's face turned hot. He looked around himself to see if everyone heard what he did.

"W-What?"

"He is bringing the cake. Which flavor?"

Oh! Cake flavor. Right. "S-Strawberry." He said trying to hide his flushed state. He walked down to Jimin who had his eyebrows furrowed as he stared at his phone.

"What happened?" Taehyung asked looking in between his cousin and his phone.

Jimin shrugged. "Dunno. He was laughing."

Taehyung bit on his lower lip trying not to flush again. "Anyway..." Jimin pocketed his phone. "Happy birthday, Taehyung. Welcome to club 18."

Taehyung smiled. "Thanks."

"How does it feel?"

Amazing. Slight pain but it was worth it. "How does what feel?"

Jimin gave him judging eyes. "Being eighteen. What else?"

"How did it feel to you?" Taehyung asked him pushing away his dirty thoughts. Jimin shrugged again. "All the same. Leave it."

Taehyung laughed looking around. His cousins were working hard at blowing air in balloons. Even Luke was taking part. He made an impressed face and sighed. "Am hungry. What was for breakfast?"

"Scrambled eggs. And they are finished now. I tried waking you up, but you didn't budge. Now go and make yourself something."

Taehyung looked at Jimin who was trying to untangle fairy lights. His gaze on Jimin made him look up. He shook his head. "Don't even think."

"Chim..." He gave puppy eyes.

"No. Make your own breakfast."

"I don't feel like it. Please."

"I am busy."

"But I am the birthday boy." He nudged him again. "And I am pouting. And if you don't make me something to eat, I'll cry too."

Jimin rolled his eyes. "You suck at being cute. Don't even try to." He threw the lights in his hands. " What do you want to eat?"

Taehyung was sitting at the kitchen platform, eating the sandwich Jimin made when he heard his uncle's laughter. His head whipped towards the door only to find him walking inside with Cian, box of cake in his hands.

Jungkook looked like he always did. Tempting. Dressed casually in a white shirt that clung to his frame, the faint sheen of sweat made his bare skin glisten. His hair fell messily over his forehead, the ocean breeze still teasing his strands. Taehyung wanted to groan at the sight.

The rolled-up sleeves gave a nice show of his tattoos and strong arms. The sight of the veiny hands brought back every hazy detail of last night.

Taehyung's grip on the plate tightened. Adrenaline rush from Taehyung's chest and directly to his groin. His uncle gave him a knowing smile and Taehyung's eyes drifted to his beautiful mouth.

That filthy, deceptive, sinful mouth.

It looked so innocent when curled into that playful grin, but Taehyung knew better. He knew the wicked things it was capable of, the way it had feasted on Taehyung, hungrily drinking and devouring as if he had been starving for ages and left him trembling and undone.

Taehyung could still feel the heat of it, the memory of its devastating touch setting every nerve in his body alight.

Something twitched in his pants, wanting to feel the softness of that pretty mouth all over himself.

Taehyung clenched his thighs as Jungkook walked towards them while Cian went straight to the living area. He took a bite of sandwich to hide his needy state.

"Hey..." Jungkook smiled at Jimin, placing the cake further away to Jimin's side deliberately before turning to Taehyung. "Here's your cake." 

Taehyung looked at him, his eyes stopping at his uncle's mouth again before he looked up to his playful eyes. "Thanks." He said. His heart raced in his chest, while his breath came in shallow pants as Jungkook leaned onto the kitchen platform beside Taehyung.

Jimin peeked into the box to have a look while Jungkook gave a slight tilt of his head as he looked at Taehyung. "Strawberry, huh? I should have guessed." 

Taehyung's eyes searched Jungkook's, his insides melting under his intense gaze. "How?" 

A smile played on his uncle's lips as he watched Taehyung. Taehyung raised an eyebrow in question. Jungkook smiled even wider and leaned in closer. "You taste heaven." His voice dripped with heat.

The husky whisper coated with the right amount of sex travelled straight to Taehyung's core and a flash of his uncle's face between his legs, his darkened eyes peeking into Taehyung's soul as he made him cry in pleasure crossed his mind. 

Familiar muscles did a flip in his belly as heat spread from his face to his toes. They curled in his flip flops without his notice.

"Oh, it's so beautiful!" Jimin exclaimed unaware of the sexual tension in the air. A few others also walked into the kitchen to have a look while Taehyung watched Jungkook who stared at him with those dark eyes glinting with their usual tease, locking onto him like a secret only they shared.

"I'll see if they need my help." Jungkook pushed himself off the counter. Taehyung nodded on autopilot. His uncle smiled and turned to leave before he stopped. "Oh... I forgot something." 

Taehyung's eyebrows furrowed in curiosity. Jungkook did a quick look around before taking out something from his pocket and handed it to Taehyung secretly. "Your favorite." 

The furrow in Taehyung's eyebrows deepened even more. Jungkook pointed him towards his hand with his eyes. Taehyung blinked unsurely as he looked down at the thing in his hand before his eyes widened. It was a condom. Strawberry flavor. 

He looked at his uncle, whose eyes held laughter while Taehyung's face turned red. He clutched the damn thing and hid it, his heart racing in fear as he looked around instinctively to see if anyone saw. Almost half of their family was there. 

Beads of sweat formed at his hairline.

Taehyung's eyes returned back to Jungkook who shrugged casually. "Happy birthday, Wildflower."

Taehyung stared at his uncle, breathless, his mind unable to process while his heart raced in his chest. Jungkook winked at him, his playful eyes trained at him for a moment longer before he poked his cheek, clearly amused by Taehyung's reaction and walked away as if he just didn't tease Taehyung in the worst of ways.

Taehyung watched his retreating back, still stunned. 

"Tae... did you see this?" Jimin turned towards him. His voice startled Taehyung back to his senses. He pocketed the condom hastily, and nodded, a masking smile on his lips as Jimin said something but the skin of his thigh burnt. He could feel the sharp edges of the wrapper biting into his skin as his mind still struggled to focus.

His heart pumped like a broken machine. Forgetting Jimin's entire existence, his eyes searched for Jungkook again. He was hanging the lights from the ceiling. Their eyes met and Jungkook gave him a wicked smile.

Fire erupted in each cell of Taehyung at his silent taunt.

His uncle was such a damn tease. And what drove him crazy was how hot he found it.

A laugh escaped his lips in disbelief when he processed it all.

He ignored Jungkook and focused on his sandwich.

*****

Taehyung smiled brightly as his mother hugged him. "Happy birthday, sweetheart."

"Thanks Mom!"

"You look so beautiful." She patted his cheek.

Taehyung smiled stepping ahead to hug his father when he asked him to. It was evening. He was getting ready when his parents came to his room to wish him birthday.

"I can't believe you are already eighteen." His father chuckled. "You were a little bean just yesterday. I was so scared when the nurse gave you in my hands. And look at yourself now... All grown up."

Taehyung laughed softly as he hugged his father, the familiar scent of his cologne wrapping around him. "Emotional speech is not what I was waiting for, Dad." he said pulling back. "Where's my gift?"

Mr. Kim raised an eyebrow. "I thought my love would be enough." 

"It never is. Specially on birthdays." Taehyung retorted. "Now gimme my gift." 

Mr. Kim chuckled, shaking his head as he reached into his pocket. "I thought you grew up, Taehyung. Fine, here." Taehyung's eyes lit up as his father handed him a small velvet box. "What is it?"

"Open it and see."

With nimble fingers, Taehyung flipped open the box to reveal a key to his favorite sports car. The sleek design and the engraved logo of a golden crest with a black horse in the middle, surrounded by red and black stripes had his eyes widened in disbelief and well as happiness.

"Porsche?" 

His father nodded. "Carrera!" 

Taehyung squealed hugging his father again. "Oh my God! Thank you, Dad!" 

His parents chuckled watching him almost dancing where he stood. Mr. Kim patted his head. "You are our only son, Taehyung. I'll give you everything your heart desires." 

Taehyung looked at his father, knowing he was being honest. His parents have always given him everything he asked for, and everything he didn't even ask for, without a second thought. "You are the best, Dad. I love you so much." He exclaimed. 

He couldn't wait to go out on a drive now. "Where is it?" he asked impatiently.

"Back at home. It will be waiting for you when we get back." 

Taehyung's excitement dropped but it didn't falter his happiness. "Can I at least see a pic?" He pouted.

His father laughed. "Of course." He unlocked his phone and showed him a picture. Taehyung didn't know how to contain his happiness. He thanks his parents again. His mother kissed his cheek, and they walked out telling him to get ready and come down as the party has started.

Taehyung was still living the happiness of getting his favorite car when Jimin walked inside. He was about to say something, but his words faltered when he saw Taehyung smiling to himself. "Why are you smiling like that?" 

"Like what?" 

"Like you just got laid in a Ferris wheel," Jimin quipped, leaning against the doorframe with his arms crossed, a smirk tugging at his lips.

Taehyung looked at him at the loss of words. "From where do you even get those answers? Is there some book titled 'how-to-give-a-sexual-answer -to -every -question -asked-101"

Jimin's smirk grew wider as he sauntered into the room. "Oh, baby, I am the book. A walking, talking encyclopedia of sass, sex and seduction. The one and only, Park Jimin."

Taehyung groaned, making a face. "You need therapy."

"I don't need therapy," Jimin retorted, flopping dramatically onto Taehyung's bed. "I need a drink and maybe someone to moan for me. I am on a dry spell for fifteen hours. I think someone from the party is getting lucky tonight. But anyway, this isn't about me—it's about you. Spill. Why that glowing smile?" 

Taehyung ignored the first part and showed the keys to Jimin. "Dad gifted me a car." 

Jimin's ears perked up. He flopped onto Taehyung's bed, propping himself up on his elbows. "What kind of car are we talking about here? Something sleek and sexy? Or are we talking big, strong, and rough on the road?"

"Why do you make everything sound like... that?" Taehyung groaned, trying not to laugh.

Jimin shrugged. "So, are you going to let me ride it? The car, I mean." Jimin asked, his playful eyes teasing Taehyung. "Now when you are eighteen, I'll let you ride me in exchange." 

Taehyung made a disgusted face. "You are impossible." He said and turned around to have a look at himself in the mirror while Jimin laughed. He wore a blue silk shirt tucked in white skinny jeans. It hugged his ass just right. He really liked the silk band around his neck, tied like a choker.

Taehyung left his black hairs to fall naturally on his face. Avoiding any makeup except concealer which hid the hickeys at his neck from eyes, he gave a touch of lip gloss to his mouth.

He assessed himself from head to toe.

He looked... nice in an innocently sexy way.

People will think it was not intentional, but Taehyung had every intention to grab eyes. Not the crowd's but his uncle's. Jungkook had been behaving normally all day long after the morning incident. He hadn't touched Taehyung in any way while he waited for those sneaky moments.

He bit his lower lip embarrassed at his attempts to look seducing, but it didn't change his mind.

"Want me to comment on how you look?" Jimin asked from behind. Taehyung immediately freed his lip from his teeth. He totally forgot Satan's spawn was still there.

"Don't you dare." He warned him.

"But-"

"No!"

"I am hard." 

"I'll chop your dick, Park Jimin!!" He threatened. He regretted the day he asked Jimin to look at him and tell him about his sexual appeal. In fact, sometimes, he regretted being best friends with him. He made life so miserable sometimes.

Taehyung can't even daydream about seducing his uncle now?

Jimin got up from the bed still laughing. "Aww.... don't be mad now. I love you." he back hugged Taehyung forcefully against his will. Taehyung groaned, acting to be mad, and tried to push him away but ended up laughing in the end when Jimin tickled him.

The two best friends walked down still laughing.

The house was decorated. The place bathed in beautiful lights. Couches were pulled to the side in the hall. At the wall, a happy birthday Taehyung banner hung below the colorful balloons.

Party seemed to have started a long time ago. The place was already full of people. Taehyung's eyes roamed around the place, taking in the known as well as strangers. He found the elders of the house by the couch, sitting and drinking. People danced everywhere. His eyes found Jake, and a guilt filled him.

He smiled at the other when he offered him a smile before his gaze stopped at his uncle behind the bar. 

Heat prickled in his belly at the way he watched Taehyung.

Taehyung squirmed in his place. Jungkook didn't look away as he handed a drink to someone. Taehyung felt electricity coursing in his veins. His uncle's gaze forced him into a submission, hypnotizing his mind but Taehyung boldness broke the spell.

He smiled at Jungkook.

Jungkook hid his smile looking away and Taehyung felt like he won some war.

Knowing that his uncle was still watching him, he walked into the opposite direction, swaying his hips purposefully. Everyone hugged Taehyung and wished him a happy birthday. People at the party gave him the gifts for which Taehyung thanked him.

Jimin brought him a drink.

The two best friends danced lazily. His eyes kept flickering to Jungkook every now and then, and every time, he caught Jungkook watching his ass. Even when Taehyung raised an eyebrow in challenge, his uncle just stared at him. While it made Taehyung smile initially, it soon made heat curl in his stomach.

The intensity of that gaze caught Taehyung off guard.

Jungkook's eyes, they were not playful anymore. They were dark. And hid a warning. Telling Taehyung to beware. He swallowed, feeling his throat dry.

His heart thudded wild in his chest while sweat covered his skin.

He walked away to drink water, but he couldn't shake away that gaze. 

The air suddenly felt too hot, and the hall grew smaller. He smiled at a few people as they talked to him, but his mind was busy somewhere else. He wondered what that gaze meant. He was somewhat scared but at the same time, that fear made him feel wet between his legs.

Fuck!

He looked back at his uncle, but Jungkook wasn't at the bar anymore. His eyes scanned the place quickly, but the man was nowhere. He shifted in his place trying to ease the need down there. He gasped when he felt a hand at his ass.

"W-"

"Shh..." Jungkook shushed him, groping his ass on his way as he came to stand in front of Taehyung. "Searching for me?" 

Taehyung, who jumped at the action, composed himself quickly. "No."

Jungkook laughed shaking his head. "You are a terrible liar, wildflower." 

Taehyung's stomach flipped at the name. It was the second time his uncle called him that, and he didn't seem to notice it himself, but Taehyung did. He ignored the way his heart fluttered and smiled.

"Okay, maybe I am. What are you going to do? Punish me?" He shifted in his place still feeling his uncle's touch on his ass.

Jungkook raised an eyebrow. "Talking about punishments... are we?"

Taehyung nodded, doing a quick scan around. "You talked about punishments the night you agreed to it. I wonder if you were being serious or just said that for the sake of it." His eyes stopped at Jungkook, and he gave a light shrug, acting to be confident even when his nerves twisted at the thought of those words coming true.

"Fair enough." Jungkook said. "You'll see if they were just empty threats but not today. It's your birthday so you are forgiven." 

Taehyung looked at him in disbelief as well as disappointment. Taehyung had so many expectations from his uncle. He thought he would be wild. And relentless. And here he was, treating him like it was Taehyung's tenth birthday!

"It's time for the cake cutting." Jungkook reminded him.

Taehyung looked at him and rolled his eyes. "You are boring." He said and walked away from there, hearing Jungkook laughing behind him. Taehyung cursed him under his breath. He dressed like that... for what?

Get babied?

All of his cousins gathered around the cake as Taehyung picked up the knife. He knew what was to come and he dreaded it. On each of his birthday, as soon as Taehyung will cut the cake, all of his cousins will jump onto it, not to eat but to paint it across faces.

They called it tradition. Taehyung called it stupid tradition.

He took a deep breath and braced himself. He knew the strategy. Just cut the cake, offer it to his parents and step back before the sea of bodies consume him.

He did the same. Everyone clapped and wished him as Taehyung blew the candles and cut the cake. His father smiled when Taehyung offered it to him before his mother. The crowd started closing in, and they pushed Taehyung into the far background.

Taehyung gasped, almost falling, but his back hit a hard chest behind him.

If Taehyung's heart was thudding wild in his chest earlier, it almost came out of his mouth when he looked up to see it was his uncle holding him possessively. His big hand sprawled across Taehyung's stomach ignited a fire from where it spread all over his body.

His chest rose and fell erratically.

It's when he noticed the shadow on Jungkook's face that he realized they were standing under the staircase, hidden from all the eyes.

Jungkook's eyes flickered somewhere, and Taehyung followed it too, only to find it trained at the pink cream along with the cake crumbs at his fingers. The commotion around them faded. All Taehyung could hear was his blood roaring in his ears as Jungkook held his hand.

Jungkook took the stained fingers to Taehyung's lips which parted as his heart beat like a broken machine in his chest and leaned in to kiss him on his mouth, his tongue darting out to lick them off.

Taehyung's knees turned jelly at the way Jungkook groaned, pulling Taehyung to himself from where his hand rested on his stomach, sucking his fingers, and his mouth all at once.

Taehyung stumbled, his weak knees not able to hold his weight but Jungkook's arms around him kept him upright.

His eyes closed, and head felt light as he struggled to match Jungkook's passion. His uncle kissed him hungrily, as if laying a claim, not just on his lips but his existence and Taehyung surrendered without any fight.

His breath hitched when his mind processed Jungkook's hardness pressing in his ass. Jungkook left Taehyung's fingers and held him gently by his neck as he pushed his tongue past Taehyung's lips. Taehyung's hand curled around his uncle's collar.

He struggled to breath. Sweat rolled down his spine beneath his shirt.

He moaned into Jungkook's mouth who groaned again only to kiss him even deeper.

Taehyung felt dizzy. Lightheaded. Every cell in his body was burning but he didn't know if it was from need or the lack of oxygen.

"U-Uncle Jeon!" He struggled with his words, feeling as if his soul would leave his body any moment.

Before he could drift, Jungkook pulled back sucking his lower lip once more. His heavy, hot breaths fanned Taehyung's face as he still held the boy to himself.

"You remember you asked if being eighteen matters?" Jungkook asked, his voice so deep that Taehyung felt it in his bones.

He nodded, everything within him trembling.

Jungkook smiled now tracing Taehyung's cheeks with his thumb as his fingers still curled around Taehyung's throat like a collar. He leaned in closer to Taehyung's ear. "It doesn't changes much...." He murmured.

Taehyung swallowed to sooth his dry throat. He was thankful Jungkook still held him. He will fall if his uncle let go.

"It doesn't change much, really." He said again. "Except that I don't have to stop myself anymore!"

Taehyung breath stuck in his throat. Each word of Jungkook sent a shiver down his spine.

Jungkook let him go and Taehyung stumbled before he balanced himself and turned to look at him.

Jungkook smiled at him, a very familiar look in his eyes. "I'll be waiting in your room, wildflower. Take your time here... If you can wait, that is." He whispered the last part, and smirked.

Liquid heat replaced the blood in Taehyung's veins as his mind processed Jungkook's words. His uncle stared at him for a few moments, his eyes conveying every dirty intention he had for Taehyung before walking away.
