Nine months ago; At Namjin Engagement Party 

It was one of the most important days for both Kim and Jeon families. 'Cause Jeon Namjoon and Kim Seokjin's engagement party was to be held that night. 

It was organized grandly at Jeon mansion. Most of the rich bachelors and upper classed people in Seoul could be seen inside the huge living room, talking to each other while sipping expensive liquor. 

While Jeon Namjoon and Kim Seokjin kept talking with Mrs.Kim, Michelle came over to them and bowed politely. 

"Excuse me master,"  she said looking at Namjoon and he nodded for her to continue. "Um.. Master Jungkook told me to send Master Seokjin in to help him with the dress."

Namjoon looked irritated for a second as he said, "Don't we have enough maids to do that?"

"Shh..Joonie, please don't make a fuss about it." Seokjin smiled, kissing Namjoon's cheek. "I'll be back in a minute."

Joon stared at his soon-to-be fiance's back, who was now going over to the stairway with Michelle following him from behind.

................

Jin reached Jungkook's bedroom upstairs and knocked on the door. 

"Who is it?" Jin heard a faint noise from inside and replied, 

"It's me, Jinnie hyung."

"Oh, come in hyung." 

Jin nodded at Michelle to leave and entered the room before closing the door behind. Then turning around, he looked at the younger who was busy fiddling through the large pile of shirts on the bed. 

"Hyung, can you help me to choose one?" he asked, not even glancing at Jin. "I'm running late but can't find a better color."

"Anything would look good upon you, Jungkookie." Jin complimented as he started to look through the pile as well but Jungkook just rolled his eyes at that.

"Hyung wants me to look professional." he explained. "But I don't get what he meant by that."

"Do you have a white coat? Or a blazer?" Jin questioned while taking a plain white crew-neck. 

"Not white but I remember having a light purple blazer? I'll try that on, then."

"Okay, I'll stay here." Jin agreed, trying to die down the building desire to watch Jungkook change in the closet. He would look absolutely amazing, naked. 

.............................

"Oh m-my..!" Jin exclaimed, as Jungkook came out of the room all dressed up. The purple blazer, white pants and shoes made him look ethereal. The neatly done hair was falling over his eyes a little. 

"How do I look hyung?" Jungkook beamed at Jin, expecting a good answer. 

"Y-You look.. f-fabulous..!!" Jin replied, trying so hard not to loose his sanity. 

"Oof..!" Jungkook sighed in relief and move forward to tangle arms with Jin. "Can we go now hyung?"

"Yeah, sure.." 

.....................

As they climbed down the stairs, Jin heard a soft gasp beside him and when he turned around, saw two women staring at them with admire. 

"Wow..! What a matching couple!" one of them whispered. 

"They look so cute together!" another man remarked. 

"Why aren't they even a couple in the first place!?" 

Jin blushed heavily, hearing their talk. So they really do look good together, right?" 

"Hyung?" Jin had to break his train of thoughts as they stopped at the foot of the stairway. He looked at Jungkook and nodded. 

"What should I do now?" 

"Go and blend in." Jin said, half-heartedly. He didn't want to let the boy go away from his hold. "Try to make some friends."

"How can I be a friend for these old dudes?" Jungkook scrunched his face, annoyed. "Can't I stay with you hyung, pretty please?"

Jin would've love his idea if it was another time but right then, he needed to stay beside Namjoon as the main parts of the function wasn't over yet.

"Sorry Jungkookie, you know your hyung needs me." Jin patted the younger's head and flashed an apologetic smile his way.

"Oh I know hyung, sorry.." Jungkook heaved a sigh, hugging Jin's arm more tighter and looked around. That's when he spotted the bar corner at the end of the room.

Jin followed his gaze and said, "Oh no no, don't even think about that honey!"

Jungkook looked up at him with puppy eyes. "I've already tried some of them at parties?"

Jin cocked his brow and grinned. "You're one mischievous little monkey. But no, I'm not allowing you to drink today."

"But the media isn't here today, right? So please, just one glass hyungie?"

Jin sighed. He knew he never could say no to Jungkook's requests. "Okay then, just one champagne glass. And I've got my eyes on you, okay?"

"Thank you hyungie, you're the best!" Jungkook heaved up and pressed his face against Jin's neck before heading to the bar corner. 

Jin stood there, blushing like mad because of the hug. 

"Jinnie!?" 

Jin turned his head slightly to see Namjoon beckoning him closer. He adjusted his coat and went over to him, smiling. 

"Where's my troublesome brother now?" Namjoon asked, holding Jin's hand with love.

"Oh he just went to make a friend or two." Jin assured, secretly side glancing at the bar corner where he saw Jungkook ordering a drink from the man behind the counter.

.......................

As the events of function took place of the party constantly, Jin forget to check on Jungkook. Both him and Namjoon were too busy talking with guests and receiving congrats, that none of them noticed the young boy gulping one after one of champagne glasses at the bar corner. 

However, Jackson who was about to walk out of the mansion saw this and hurried over to Jungkook. 

"Master Kook!?" Jackson spoke in an irritated voice and pulled the glass away from Jungkook's fingers. "What the heck are you thinking you're doing?"

Jungkook blindly searched for the glass on the table top, hanging his spinning head low. 

"Master would kill me if he sees you like this," he spoke again and tried to pull the young boy up from the stool. "Come on, let's get you to the bedroom."

Jungkook shook his head tipsily as he mumbled, "Give me one more."

"One more? Oh god, you're so drunk." Jackson pulled Jungkook up and leaned him to his side, not letting the half-conscious boy trip over. Then he turned to the bar attendant and glared at him.

"You better prepare to get fired!" Jackson spat and walked away with Jungkook from there. 

Meanwhile Jin was also a little drunken due to having a few glasses with Namjoon after engaging but kept himself sane enough to talk properly. However he felt exhausted and sleepy, 'cause it was almost midnight and the party wasn't finished yet. 

He fluttered his droopy eyes and yawned, taking a look around the room to guess how many people are still there. That's when he caught Jackson's figure dragging someone shorter than him alongside and it didn't took longer for him to recognize it was none other than Jungkook.

Jin placed his red wine glass on a nearby chair and hurried over to Jackson, trying his best to walk in a straight line. 

"Jackson, wait!" Jin shouted out as the loud music kept booming throughout the place. 

The latter stopped, hearing Jin's voice and smiled at him tiredly. 

"Good evening sir! I was just taking master Kook back to his room. He's drunk."

"Oh!" Jin realized his fault and frowned. "Little brat, he is. I'll take him from here"

"He's very heavy sir, do you need any help?"

"No, I can manage that, thank you." Jin reached for Jackson's side and carried Jungkook in his arms effortlessly. Then without even glancing back, he started to climb up the stairs.

Halfway on the stairway, Jungkook started to squirm and moan in Jin's hands. 

"L-Love..!!" 

Jin froze upon hearing the word but as soon as he realized it was made for Taehyung, started to walk back up with tightly pressed lips.

"Love, p-please kiss me!" Jungkook whined, embracing his hands around Jin's neck.

A sudden electric spark ran down Jin's spine as he stepped at the dark wide corridor. Jungkook leaned forward to kiss Jin's neck and groaned. 

Even Jungkook was drunk as hell, he still looked so ethereal. The cuteness never left his facial features and the dress gave him more of a sexy look. Jin couldn't even imagine how a person could be this beautiful and hot at the same time.

"C-Come on love.. What are you waiting f-for?" 

"Ssh..J-Jungkook, I-I'm not your l-love..." but Jungkook didn't hear that.

Jin made him stand on the floor and even before he blink, Jungkook attached their lips together.

The spark kick started to flame up the insides of Jin's body as the younger desperately sucked on his lips, wrapping his hands around the elder's neck. 

"Mmh..." Jungkook moaned as he pressed their bodies more closer.

Jin who had been keeping his sanity all night, lost it and in the next second Jungkook was slammed against the nearby wall. Jin slid his hand down Jungkook's hips to his thighs and hooked it around his torso while taking control of the heated make out session.

"B-babe" Jin groaned as Jungkook rubbed his erection on his lower stomach. 

"L-Love..I need you" the younger mewled, tossing his head back as he felt Jin's tongue swipe across his adam's apple. 

Jin didn't answered in words as he slightly squeezed Jungkook's ass, earning a shaky moan from him.

Bit by bit they started to stumbled across the hall towards Jungkook's bedroom. It was not that easy though as they couldn't keep their horny hands off of each other. They were all over them. 

After some minutes, Jin found the door-knob to Jungkook's room. He frantically jolted it which surprised the author as why it didn't came off to his hand. 

However, the door opened after a while and both of the boys stumbled inside. Jungkook was ripping Jin's tie off and the elder kept trying desperately to remove his thick black coat. 

Jin kicked the door shut and led the younger to bed after getting out of their every single piece clothes.  

Somehow, the rest of the wild sounds were drowned down by the blasting music downstairs as Jin raped the little boy twice that night. 

Reminder (Must read):- 

~In Chapter 3, Jungkook mentioned Taehyung about the engagement party and there he told him, how he got drunk that night and woke up in his bed the next morning without knowing who carried him there. 

~In Chapter 9, it was mentioned that Jin had a fearful memory in the furtherest corner of his mind. He suspected that either the condom Taekook couple used was broken or another thing (which was given in a blank that time) for Jungkook to get pregnant. 

~In Chapter 17, it was told that Jin was having a specific nightmare which he fears to see. And before it, it was mentioned that how he kept a dark secret away from his best friend Ken. 

~I, the author myself never confirmed Seok-hyun as Taehyung's baby. 

Match the dots and you'll see how the story builds up on it's own. I hope there aren't any loopholes this far.
