Their first kiss was… clumsy. Kageyama honestly hated the very fact that this sort of thing ever happened to him. He didn't regret kissing Hinata, oh no, and with practice, lots and lots of practice, they somehow managed to avoid repeating that scenario. And yet, every thought about how it began sent an unpleasant chill down his spine.
Hinata was too eager, his teeth bumping into his lips, metallic taste of blood in his mouth making Kageyama immediately withdraw. He himself wasn't sure how to proceed from now on, but he knew this wasn't how it was supposed to look like. He was nervous and confused, unsure of every single thing he did, it was the first time he kissed anyone, damn it.
So he placed his hand on Hinata's cheek and holding his head still, covered the other's soft lips with his own. This time it was gentle, slow, and controlled, at least until Hinata decided to swipe his tongue on Kageyama's bottom lip. As a natural reaction for a completely new sensation, Kageyama gasped in surprise, which prompted the other to sneak further into his mouth, taking the last strands of control out of his hands.
It was a new experience for them both, and Kageyama found himself quite liking the strange dance their tongues did. It was wet, and sloppy, at one point he even felt drool leaking down his chin, but there was something he couldn't quite name that kept him going and wanting more. Only when they stopped, breaths mingling together as they pointlessly tried to calm the wild beating of their hearts, did Kageyama notice what it was that he felt.
Hinata's cheeks were reddened, the hue contrasting with his hair, reminding Kageyama of the sunsets in summer; brown eyes were lightened with internal fire that made the pounding in his chest even louder, and wet lips glistened with unspoken invitation. In that single moment, Kageyama knew, he was doomed. No matter how sloppy or how clumsy their kisses would get in the future, he was never going to give them up. And till this day he didn't.
