When Cas had decided to come with Dean and his brother on a hunt. this hadn't been exactly what he'd had in mind. By the way Dean described it, Cas was sure that hunts worked like a finely tuned machine when it came to the Winchester brothers. Nobody had told him that they would spend the whole time fighting.
"I told you Dean, we're looking at a vengeful spirit! Dragons kidnap people, they don't murder them!"
"But the only people dying are virgins, Sam, tell me that isn't suspicious!"
"There are such things as coincidences!"
"No there aren't!"
Cas cleared his throat, trying to get the brothers' attention. "Dean, I-"
"Shut up Cas!" Dean cut in, before continuing, "Well sure, Sam, we've got a perv ghost with a virgin fetish, and that makes complete sense!"
"Dean-"
"And this is how you act all the time, you know?! If you just listened to me for once-!"
"Dean!"
"Shut up, Cas!"
Cas couldn't take it anymore - a surge of anger reared in him, and suddenly his lips smashed into Dean's hard, hands pushing through his hair, Dean's cold, sweet lips pliant beneath his own, a feeling that he'd never known rushing tightly through his veins. As their lips connected, Cas was a spring ready to be released, an inch from the line.
Though it felt like a million years, longer then even Cas had ever existed, in reality, the kiss lasted for about three seconds. When Cas pulled back, Dean's hair was sticking up messily, lips warm and wet and swollen, eyes dazed as he stared at Cas blankly. In the corner, all arguing forgotten, Sam coughed awkwardly, muttered something about getting something to eat, and left.
When the door slammed behind him, it was as if the spell was broken. Cas remembered now - humans didn't like to kiss when it wasn't their choice, when they both didn't lean it. Dean had probably hated that, probably hated him now, and suddenly feelings that were all-too-human were filling Castiel's mind with doubt.
"Dean," the angel started, "I'm so-"
But then Dean, Dean with his bright green eyes and sticking-up hair and rough, war-weary shoulders was leaning in, closing his eyes as he gently touched his lips to Cas'. This kiss was different - softer and more caring and somehow more passionate. Cas had once read that sparks flew when two people kissed, and he could certainly feel those sparks now.
As the angel leaned in, Dean pushed a little harder, hands wrapping around Castiel's in his lap. After a few long, sweet seconds, Dean pulled back, raising one hand and touching the hair on the nape of the angel's neck lightly.
"God, I love you, Cas."
Cas gave a small, happy smile. "I love you too, Dean, as long as you keep your arguing to a minimum."
Dean laughed softly, voice ringing in the small motel room, and leaned in again.
