"But I could show you what's going to happen once we have sex", Jungkook whispered, reaching for Taehyung's hands. "How?", Taehyung asked surprised, fully unaware of how much Jungkook was capable of.
"I have superpowers, remember?", Kook laughed and wiggled his eyebrows. "Let me just-"
He put one of his fingers on Taehyung's forehead and focused. "Shut your eyes", he said and Taehyung did so, closing his eyes as his vision went blurry and his thoughts vanished from his mind.

"Remember that whatever you're going to see isn't real yet, don't freak out", Jungkook bit his lips before he put his other hand to Taehyung's heart and that's when everything went black and as soon as Taehyung opened his eyes again he wasn't in his bedroom on the spaceship anymore.
The boys stood in the middle of nowhere, a ground where no grass was growing anymore, the sky was colored in a dark gray-ish and it was raining.
Yet the smell of burning made Taehyung panic a little, at first he couldn't make out where it was coming from but soon enough he realized that there was fire everywhere.
There used to the a forest but it was standing in high dancing flames, covering the whole area. Every flower that used to grow here was gone, the trees burned and had lost every color.

There was nothing left.

"Turn around", Jungkook whispered, he was standing next to Taehyung, quiet until now.

Taehyung listened and turned around, looking at what used to be their spaceship, their home for hundreds of years. In flames. Crashed to the ground.
Jungkook gulped when he saw Taehyung's mouth dropped open, "Where is everyone?"
The younger took Taehyung by his hand and pulled him over to the destroyed spaceship. They stood in the middle of ruins, there was nothing left.
"There", Jungkook replied and Taehyung saw dozens of dead bodies. They were all burned but some were still recognizable.

Jimin, Hoseok, Yoongi, Gigi - Taehyung found them all, laying there with ripped off skin and burned hair. "Where are we, Kook?", Taehyung turned to Jungkook, looking at him anxiously.

"Earth."

Taehyung went quiet.
It was Jungkook who continued on and dragged Taehyung further away from the ship, heading inside the burning forest. "Stop, we're going to get burned", Taehyung let out in fear but Jungkook smiled a little, "We can't get burned by our own flames, Tae", he promised and then dragged him along.
"Our own flames?", the older asked in disbelief. "What did we do?"

Kook didn't reply, instead he stopped in front of a wall where dead bodies were hung everywhere. Just that those didn't look human, they had pink skin and huge, blue eyes and lips and where extremely tall and slim.
"We won the war", Jungkook said bittersweetly. Even he looked sorry for what they apparently had done.

"We?", Taehyung asked, he was still shocked.

"We", Jungkook nodded, "You and Me."

Taehyung looked down to his feet, trying to put his focus on that to get rid off the dizzy feeling that was coming over him. So they killed everyone, every fucking being around.
"Kook why did we do this?", Taehyung asked slowly, reaching for Jungkook's hand. There was something inside of him that felt comfortable around here, knowing he did all of this - it satisfied Taehyung. Even though he knew that whatever happened around here, it was wrong and it was evil. Yet it fulfilled the deepest desires inside of Taehyung.

"You tried to save me", Jungkook whispered, "When it should have been you that needed to be saved."

Taehyung gulped, stepping back a little, "Is there anybody left?", he asked slowly, looking around. Surrounded by death and fire, this almost looked like how he imagined hell. Not earth. In school they had learned about how the earth was covered in nature, green everywhere and animals living happily ever after.
But that was back then and this was now. Nothing but smoke of the fire, dead humans, aliens and animals and a smell of regret. "Goddamnit Jungkook we ended the world", Taehyung let out anxiously, "We ruined everything."

"We did what had to be done", Jungkook shrugged.

"Ending the world did not had to be done like this!", Taehyung cried out, "We killed everyone!"

"See, and this mindset is what you need to keep to avoid all of this happening", Jungkook giggled, patting Taehyung's back.
"All of this can be avoided if I don't fuck you?", Taehyung laughed out in disbelief, "Didn't know sex could be so significant in a relationship."

"Well", Jungkook smirked, "What do you think happens if you sleep with the devil, huh?"

"Stop", Taehyung's breath hitched, "That sounds way too hot if you say it like this."
Jungkook grinned and moved a little closer until their lips almost met, "See? And that's the problem. You think it's hot fucking with the devil when it could literally end the world."
He pressed a little kiss to Taehyung's lips and the older could feel it in his whole body, like electricity rushing through his veins. Kissing Jungkook felt like taking drugs, it came along with so much joy and passion and not the slightest doubt that it could be wrong.

"What if it's already too late?", Taehyung asked.

"It is", Jungkook shrugged, "It's only a question of time now until you give in. I can't wait for that", he grinned, letting his hand brush along the older's arm until he reached his hand once more, "Ready?"

"Ready for what?"

"Don't you want to see what future Jungkook and Taehyung are doing right now?", the younger asked, sounding way too excited for what was about to happen. Tae nodded, doubting his future self already.
Jungkook turned around and dragged Taehyung along to a small cabin that stood in the middle of the fire but wasn't burning at all.
"We're in there?", Taehyung asked confused.

"Yeah", Kook nodded, "Come on~"

He walked over to a window and brushed with his hand over the glass to get rid off the dirt that was covering it. "Why don't we just walk in?", Taehyung asked.
"Because we'd break the rules of the universe if we'd look our future selves in the eyes", Jungkook explained and then looked inside, Taehyung doing the same.

And there they were, on top of a small bunk bed, clothes thrown to the ground. There was a dead body laying in the corner of the room, blood everywhere and knives pinned to the wall.
And in the middle of all of this, Jungkook on Taehyung's lap, riding his cock happily. Their bodies were melted to each other, the younger was crying in joy and Taehyung kept kissing the younger's neck while fucking into him.
"Damn", Taehyung let out and Jungkook smirked, "I honestly can't wait for this day", he whined and stepped a little closer to Taehyung. The older wrapped his arms around Jungkook, hugging him while he watched their future selves.

"There's blood everywhere, even a dead body and we seem like we wouldn't care", Taehyung pointed out and Jungkook smirked, nodding. "It's because we really don't care."

They watched for a little longer until Taehyung finally had seen enough and turned to Jungkook, "Can you also show me what happens if we won't have sex?"

The younger's face expression dropped immediately, "Are you sure you wanna see that?"
"Yes."
"It will break your heart, Tae."
"Show me-"

The younger sighed and put his finger on Taehyung's forehead again, the other onto his heart and everything went black once more.

They were standing on the spaceship, well-, Taehyung was standing on the spaceship, looking around anxiously because he couldn't find Jungkook anywhere. "Kook?", he asked and started walking around, trying to find the younger.
Until he ran into Namjoon who seemed to be in a hurry, "Namjoon!", Taehyung yelled out, "Where's Jungkook?"

The older looked irritated for a second, "What? Taehyung, are you okay?"

"Yes why wouldn't I?!", Taehyung blurted out.

"Because you yourself killed him-, ages ago."

Taehyung's vision went blurry once more and before he could even react he found himself back in his bed, in their present time and with Jungkook sitting besides him who looked at him with big, teary eyes. "Sorry", he whispered, "I didn't want to show you this version", he hummed, looking upset.

The older was quiet, tears filling his eyes.
"So it's either the end of the world or the end of you?"

"You haven't seen everything, Tae", Jungkook hummed, "If it's the end of me, you might save the human race."

Taehyung gulped, tears falling off his cheeks, "I could save everyone or-"
"Or just me", Jungkook smiled sadly.

"How am I gonna do that?", Taehyung asked but Jungkook shook his head, "You'll figure it out."

"I can't carry the responsibility for killing everyone", he whispered, "But I don't want to be the one killing you."

Jungkook only smiled peacefully.
Even though Taehyung had no clue yet what he was going to do, Jungkook already knew which one of the two versions he had shown him was going to be the reality and which one he made up.

"It's all going to be fine, Tae. No matter what you choose to do, you'll be fine."
