Jungkook truly hadn't meant to giggle. He was actually quite horrified, especially because he hadn’t even realised that he’d done it until he saw that Namjoon had stopped talking to Taehyung, and that they were instead both looking at him.
Jungkook tried to cover his mouth, but the giggles wouldn’t stop and Namjoon and Taehyung were still looking at him with confused expressions.
Now, he could have just crawled away and out of the room, but Jungkook rationalised that the logical, and proper, thing to do would be to explain to them why he was laughing. Since, well. He was laughing because of them. Or because of Namjoon at least.
Then it hit him that the whole ‘doing the rational thing’ was something Namjoon would do, which just made him laugh harder.
“Jungkook, are you okay?”
Jungkook nodded at him the best he could, giving that he was sitting against a wall, arms halfway covering his mouth.
He took a deep breath to try and stifle the giggles still escaping him. “Yes, yes hyung, I’m fine,” he said when he was able to get some air down his lungs again.
‘This is ridiculous,’ he thought while damning the universe for making him giggly when tired. ‘This was never even funny.’
And because he then felt even more of a need to explain himself, he started crawling across the floor to where the two others were sat.
Telling Namjoon first seemed like the best idea, so he put one hand on Namjoon’s thigh and hoisted himself up until his mouth was close to Namjoon’s ear, and his body was flush against his hyung’s.
“Hyung, it’s just that when you were talking to Taehyung,” he whispered, “you looked so daddy.” Jungkook pushed himself a little away from Namjoon so he could look at the other man.
Namjoon’s lips were slightly parted, and Jungkook definitely thought that the other’s eyes where shining a little. That was good. Probably meant that he understood.
Still, he had decided to explain, and Jungkook was the kind of person who finished what he started.
Jungkook licked his lips. “It was very hot, hyung, I didn’t know how to react or…” Jungkook took a moment to look down at Namjoon’s lips before continuing. “Or what to do.”
When Namjoon answered, Jungkook thought that his voice sounded a little breathy beneath the curious tone. “So you laughed because..?”
“Because I found it so surreal,” Jungkook edged even closer, “that I had never realised how hot that was until now.”
