Jungkook ran his fingers through Taehyung's hair until the elder fell asleep. He had moved them under the blankets shortly before, both snuggling further into each other. Taehyung passed out quickly after that, his head resting on Jungkook's chest.

They didn't talk much after the sex. Nothing needed to be said. They simply took pleasure in each other's company. In just being there in the moment.

Jungkook marveled at the sleeping boy, feeling something stir in his chest. It felt like a warmth expanding, radiating throughout his body. And the cause was Taehyung alone.

He was falling for his best friend.

It would be easy to blame these feelings on the sex. Part of him was subconsciously suggesting he take that as an easy out. It would be far simpler for him to say their intimacy triggered these thoughts than the alternative. But if he was being honest with himself, he knew these feelings started way before they slept together.

It was hard to pinpoint the when. But it was so easy to point out the why.

Taehyung made him feel safe in everything he did. In exploring his sexuality, yes, but beyond that. Ever since they were teenagers, he knew he'd find a sense of security, of comfort, within the elder. He was never a risk taker alone, but with Taehyung by his side, he wanted to try everything and to see what the world had in store.

Jungkook was also able to fully be himself with Taehyung. His silly side came out full force and he wasn't afraid of looking stupid or childish. They had fun together and could make any experience an adventure.

Jungkook could go on and on about the qualities he loved in Taehyung. His depth. His charm. His kindness. His energy and enthusiasm. Not to mention his deep voice and sexy ass. Beyond all these qualities though was the totality of Taehyung. Everything he was drew in Jungkook more and more with each passing day.

He was falling for his best friend and he was so excited and absolutely terrified.

He caressed Taehyung's cheek, his thumb brushing over the freckle on his lip. God, how he yearned to kiss him there. He leaned closer, his lips just centimeters away from the elder's. 

But he couldn't do it. Wouldn't do it. Taehyung had asked Jungkook to respect just one rule and he would. Even though it caused his body to ache, he would not breach Taehyung's trust.

He finally fell asleep, with Taehyung in his arms, thinking about one day getting to finally kiss him.

Taehyung awoke hours later. Jungkook's arms were holding him tightly, and Taehyung's own arms and leg were wrapped around the younger. It was such an intimate embrace, but Taehyung found himself leaning more into it.

He smiled as he nuzzled into Jungkook's chest, replaying their steamy, but caring, experience. Thoughts flooding back, he finally realized his ass was hurting him. But he'd do it all again in a heartbeat.

Taehyung wanted to make Jungkook feel that good too. It was something he'd never felt before and he loved it. Two months ago he'd have scoffed at the idea and say he'd never let anything up his ass, but he definitely had a different opinion now. He knew Jungkook would enjoy it just as much as him.

And selfishly, Taehyung really wanted to fuck Jungkook. Ever since he envisioned pulling the younger's hair while slamming into him, his blood had been boiling at the thought. He was excited to try it soon, though he wanted to give as much thought and preparation as Jungkook had done.

Taehyung felt immensely cared for during their experience. It was obvious how much Jungkook wanted it to be good for him. And he seemed knowledgeable and in control the entire time. It allowed Taehyung to feel safe and truly relax. He didn't think he could do that with anyone else.

He carefully unwound his arms from Jungkook so he could get out of bed. He found Jungkook's phone on the dresser and took it back to bed with him, reclaiming his spot within the younger's arms.

The phone's lock screen showed a dozen texts from Chloe. Taehyung pulled down the messages to see a preview of what was sent, not wanting to pry completely but also very curious. He quickly got the overall gist of the messages.

Chloe was pissed. Jungkook hadn't been in contact with her for over a week.

Taehyung, knowing Jungkook's password, unlocked the phone and went straight to the internet. He decided he already snooped enough and shouldn't look at any more messages, even though he was eager to know what Jungkook had been texting Chloe. If anything at all.

He then spent the next hour doing research of his own. He wanted to make sure that when the time came, he'd be ready to give Jungkook just as amazing an experience as Jungkook gave him. He was determined to make it as pleasurable as humanly possible.

By the time he felt thoroughly prepared with new knowledge and a plan, Jungkook started to stir.

Taehyung watched as his eyes flitted open. "Hey, baby," he said softly.

Jungkook smiled, his eyes drifting closed again. "Tae."

Taehyung smoothed back his hair. "Go back to sleep," he murmured.

Jungkook rested his head against Taehyung's, his body going limp in sleep. Taehyung chuckled, setting the phone on the bedside nightstand and sliding his arms around the sleeping boy.

He kissed his cheek. But a small part of Taehyung wanted to kiss Jungkook somewhere else.

Maybe he'd need to rethink his one rule.
