"So next month is Jungkook's birthday. What do you think would be the best gift?" The eldest, Seokjin asked as he played with the chemicals.
"You guys knew Taehyung, right?" Namjoon, the third youngest asked. He kinda looked excited, tho.
"Yes, what about him?" the second youngest, Jimin asked.
"Well, as you can see... we're all scientists and... we could make a drink that would make Taehyung horny." Namjoon said.
"So you're saying that Taehyung is the gift?" Yoongi, the second oldest, said.
"Hell no. That boy is precious." Hoseok, the third oldest said.
"Jungkook is obsessed with him, Seok. He would be the best gift. Also... Taehyung would be horny so-"
"We could just buy viagra, Joon."
"I didn't say medicine! I said drink! D-R-I-N-K."
"So it will just make him horny?" Seokjin said.
"Of course not! That ain't really fun." Namjoon grunted.
"Then what?" the other four said in unison.
Namjoon smiled, and it soon turned into a smirk.
"Well, let's make his mind slip away..."

[in the classroom]
"Don't touch him!" Jungkook shouted.
The boy immediately retracted his hand off Taehyung's shoulder.
Jungkook stepped closer to Taehyung and pulled him closer to him by his waist. He glared at the guy who touched his Taehyung.
"Jungkook?" Taehyung asked in a small yet deep voice.
"Get out!" He shouted at the boy who immediately complied.
Jungkook faced Taehyung, "Didn't I tell you to stop hanging out with everyone?! Why can't you understand that you're mine?!"
"Jungkook, will you stop? I'm not yours. I am mine. I am so tired of telling you this everyday. Please, stop already. I have a boyfriend now to-" Taehyung was cut off when Jungkook slammed his fist on the table.
"Who is your boyfriend?"
"Jungkook-"
"I ASKED YOU. WHO IS YOUR BOYFRIEND?!"
"It's Bogum, alright? Stop. Let me go. Move on." Taehyung said as he tried to let go from Jungkook's tight grip on his waist.
Before Jungkook could even speak, Taehyung grabbed his book and hit Jungkook on his face. Making him lose his grip on him. Taehyung ran away. He ran away from Jungkook.

"NAMJOON! I SAID TO PUT IT IN THE SECOND BEAKER!"
"THIS IS THE SECOND BEAKER, HYUNG!"
[hyung means older brother. it's boy to boy]
"THAT IS THE FIRST BEAKER, IDIOT!"
"Seokjin hyung, calm down. He put it in the second beaker. I kinda changed the label." Jimin said.
"I told you, hyung." Namjoon said while Seokjin only rolled his eyes and continued doing his work.
It's been two weeks since they started making the drink. As conversed earlier, the drink would make Taehyung horny, but it's not only that. It would make Taehyung do whatever Jungkook would tell him. He would feel so attached to Jungkook. Well, Jungkook is gonna be his owner.
But that's not only that, it's gonna be permanent. Not only for one night, but I repeat, it's permanent. Taehyung will be Jungkook's forever.
They could still remember when Jungkook got home with a bruised lip. He said that Taehyung rejected him once again.
In those two weeks, he stopped bothering Taehyung. He's only watching him from afar, and he definitely almost lost control when he saw that Bogum guy kiss his Taehyung.
Oh, hey Jungkook. You just wait and Taehyung will be all yours.

[jungkook's birthday, 6:00PM]
"Hoseok, Jimin! Taehyung is in that cafe!" Namjoon said thru the mic.
The two heard it from their Bluetooth earphone and immediately went there and saw that the cafe is really full. Perfect.
They saw Taehyung and they got lost in his beautiful face. But heh, he's Jungkook's.
Taehyung is reading a book while drinking his cold coffee.
"Hey there, can we sit here?" Hoseok asked as Taehyung looked up.
"The cafe is really full, and there are no other seats." Jimin said.
"Yes, of course. I'm alone anyway." Taehyung said and smiled. Oh that boxy smile.

"Thanks." Hoseok and Jimin said as they sat down.
Taehyung continued reading his book and put his coffee down.
"Oh wait. I need to go to the restroom. Please excuse me." Taehyung said as he stood up and went to the restroom.
The brothers took this chance and put a pill on Taehyung's coffee. It's not the drink yet. The pill would just make Taehyung dizzy.
They then heard a laugh. It's from their earphone.
"Why are you laughing?"
"I'm sorry. Jungkook got mad at Jin and Yoongi hyung because they won't let him get drunk."
The two just nodded even tho Namjoon can't see them. Taehyung came back and greeted them.
He started reading his book again and drank his coffee.
The brothers looked intently at Taehyung as he scrunched his nose.
" Uhh, sorry. I will go now. I suddenly felt dizzy."
"Oh, my brother is a doctor. Would you like to come with us? I remembered last week, I suddenly felt really dizzy too, and we found out that I'm sick. I'm currently undergoing a therapy." Jimin lied knowing that Taehyung's too dizzy to understand what he said.
"Wha- What? Su- Sure... I'm coming with you..."
-~-~-~-
"I guess he's not home yet." Hoseok said and looked at the time.
7:10PM
Perfect.
"No. He's here. Namjoon hyung!" Jimin called out.
Because of this, Taehyung felt like his mind crashed. The brothers made Taehyung sit on the sofa as his head lolled backwards.
Namjoon came from upstairs and saw Taehyung. The drink in his hand.
"What's the matter. Who's he?" Namjoon asked, pretending not to know Taehyung.
"A friend. He said he's really dizzy. Please check on him." Jimin explained.
Namjoon nodded and sat beside Taehyung. He touched Taehyung's forehead and almost got startled when Taehyung screamed. It was expected from the pill tho.
"Here. Take this drink, this will help you." Namjoon said. Taehyung nodded, too dizzy to believe whatever they are saying.
Namjoon helped Taehyung on drinking, "It's better if you drink it all." And so Taehyung drank it all.
And after a few seconds, Taehyung is asleep.
7:30PM
30 mins before the three brothers come home from the bar.
They have enough time.
Hoseok picked Taehyung up and carried him upstairs towards a vacant room room.
Namjoon was done setting up Jungkook's room so the only one missing is the real gift.
They gently put Taehyung on the bed and stripped him naked. They wonder what's going on in Taehyung's mind, but they exactly knew what is going on.
He won't be the same Taehyung anymore. He will be Jungkook's slut, pet and whore.
Once Taehyung is fully naked, Jimin picked up the lingerie from the closet and brought it to Hoseok.
They are not gonna lie. They were surprised to see Taehyung's body. They thought it would be like of a man but heck! It's like the body of the goddess of beauty! It's also really soft and smooth. Enough with that, they dressed Taehyung in the lingerie and fixed his hair.
Once they're done, they put him in Jungkook's bed and cuffed Taehyung's hand on the headboard while both of his ankles were also cuffed on each side of the bed.
They spreaded Taehyung's thighs really wide and put toys beside him. What I meant by toys are dildos, vibrators, cock ring and more.
They looked at their work and nodded, satisfied.
They took a last glance on Taehyung's face and left. They could hear Taehyung starting to squirm tho. They sat on the couch of their living room waiting for their brothers to arrive.
7:58 PM
Jungkook barged in the house and layed straight on the couch. His face showed that he's in a real bad mood.
"Where's the Hyungs?"
"We're here." Yoongi said.
"Come on, Kook. Don't be mad at us." Seokjin said.
"Well yeah, you pulled me to that bar and then we didn't even drink! We were there for what, 2 hours! You didn't even let me see Taehyung!" Jungkook complained.
"Relax, Kook. Anyways, Happy Birthday again. Our gift is in your room." Namjoon said and winked at him.
Jungkook raised his eyebrows and stood up. He headed towards his room and when he opened the door, he could't believe it.
Taehyung is there in a lingerie and he is a moaning mess, his saliva is dripping from his mouth. His legs spread wide.
"HYUNGS!" He shouted.
When he didn't get a response, he just came into his room and looked at Taehyung. He's hard like shit.
He saw a paper on the bedside table and he quickly opened it.
Dear Brother,
We knew how much you like Taehyung so we decided to make him our gift. He's all yours now. We made a drink that will make him obey you. He's horny right now. That's the first effect. Don't ask how we did this, we just did it, okay? If you wonder, how long this lasts... it's permanent, brother. He's your slut. Enjoy~
Your five lovely brothers.
Jungkook is definitely Jungshook right now. He looked at Taehyung and smirked.
"Hey, baby boy."
Jungkook trailed his fingers on Taehyung's face down to his collarbone, nipples, stomach, thighs and then his crotch. While he is doing this, Taehyung became more of a moaning mess.
"I can't believe this, but you here in front of me makes me believe it."
"You don't know how much I wanted to do this to you. You just don't fucking understand that you are mine, hmm?"
"I didn't bother you for a whole month because I thought you would miss me clinging to you but heck, you became even more happy with that Bogum."
"Open your eyes, my dear Taehyung. Look at me. Look at my eyes."
Taehyung opened his eyes and stared at Jungkook. Jungkook put his thumb inside Taehyung's mouth and Taehyung instinctively sucked it.
Jungkook giggled, "You were always pushing me away but look at you now. So eager for my cock. So eager to obey me. Just me speaking makes you really hard." He said as his other hand palmed Taehyung.
Taehyung wanted to close his eyes from the pleasure, but the order Jungkook gave him made him unable to.
"You are mine, Tae. Mine, only mine. Repeat that for me, yeah? Say my name too."
"I- I am y- ughh- yours, Jung- mhhmm- kook. Y- your- s, on- nghh- ly yours." Taehyung repeated.
"Oh well, I didn't said it clearly, did i
I?" Jungkook giggled and slapped Taehyung's thighs causing him to moan.
"Repeat it on loop. Now!"
Taehyung started repeating it like a mantra. He repeated and repeated until it was the only thing he can think of. He didn't even notice when Jungkook ripped off his lingerie and started fingering him.
Meanwhile, Jungkook is so happy to hear it from Taehyung because before... Taehyung would only say to fuck off and he's his.
"Hush now, baby. I'm gonna fuck you really hard."
Taehyung stopped repeating his mantra as Jungkook slammed himself deep into Taehyung, fucking raw.
But instead of feeling hurt, Taehyung only felt pleasure. Jungkook thrusted into him in an animalistic pace and his eyes rolled back when Jungkook hit his prostate.
Jungkook kissed Taehyung and his tongue explored Taehyung's mouth. Damn, he is really delicious.
He is trailing his fingers on Taehyung's body until it stopped on Taehyung's hips. Digging his fingers deeper, making sure to leave marks.
Taehyung moaned as he felt the pain, but that pain gave him more pleasure. He couldn't think. His mind clouded with Jungkook.
Jungkook fucking owns him.
He will surely do whatever Jungkook tells him. The most important thing for him is Jungkook's happiness, and nothing more.
"I'm coming, baby. Come with me." Jungkook grunted.
Taehyung moaned loudly as he came. He felt Jungkook's cum filling him, and it's wonderful.
Taehyung looked at Jungkook in the eyes. Jungkook is smirking at him.
"We're not finished yet, baby. We have to use all of this toys after all."
~♡~♡~♡~
"Wh-What do you mean, Taehyung-ah? Did– Did I do something wrong? Please tell me so I can fix it! No need to break up with me! Please... Taehyung..."
Bogum was about to touch Taehyung when he took a step backward.
"I don't want anyone else touching you." Jungkook said.
"I just... I fell out of love, Bogum hyung." I'm Jungkook's now.
"That's absurd! We were so happy just a week ago! You disappeared and then now that you're back, you're breaking up with me!"
"I'm yours, Jungkook. Only yours."
Those words kept repeating on Taehyung's mind. It's the truth tho, he knew to himself. Jungkook owns him.
"You're mine, right?"
"Yes, Jungkook. I'm yours. Why do you ask?"
"You're still with Bogum."
"Oh... do you want me to break up with him?"
"Can you?"
"Anything for you, Jungkook."
Taehyung looked at Bogum's eyes. Jungkook would love it if I break up with him. He'll be so happy, and that's all I want now.
"That was a week ago, Hyung. I'm sor—"
No, he's not sorry at all. Why would he be sorry at something Jungkook would love?
"I'm leaving now." Taehyung said as he turned his back at Bogum and started walking away. Leaving Bogum a crying mess.
Taehyung walked to the coffee shop where Jungkook said he'd be waiting. His eyes roamed at the shop, trying to look for Jungkook as he entered.
When he saw the boy he's looking for, he quickly made his way towards him.
"Jungkook." Taehyung called his attention and sat down in front of him.
Jungkook looked at him and smiled.
"Hey, Taehyungie. How did it go?"
"I broke up with him."
Jungkook smirked and held Taehyung's small hands.
"Did you let him touch you?"
"No."
Jungkook nodded as he stood up. The smirk on his face never seem to fade.
"That's great. I'm so happy, Taehyungie. I hope you'll continue being a good boy for me."
Taehyung's heart swelled with happiness. He made Jungkook happy by being a good boy for him.
He'll make sure that he's Jungkook's good boy forever.
