A little William x Sebastian thing for a friend. Kinda gloomy kinda weird, I'm still getting into the swing of writing all these different characters. Set before Sebastian takes the contract with Ciel.

He knelt on the roof of some old building, pulling his black coat further around himself. The high winds were cold and damp, although the clouds above - grey and swollen with rain - had yet to release their load upon the dismal town he had found himself in. Heavy black boots squeaked as he turned slowly to look over his shoulder, staring at the other man on the roof.

"William."

The reaper frowned at the demon, carefully walking across the slats of the slanted roof to stand besides the other man. Looking down at him, his long black hair perfectly hid his face, his those sharp burgundy eyes, the color of spilt wine. The demon looked up then, turning away from the humans far below them, on the streets of London.

"It's going to rain. It'll at least keep the fire from spreading any further."

"Fire? You're making less sense than usual, demon." William slowly knelt down next to the raven haired man, watching the way those awfully intense eyes tracked every movement he made, like some sort of wild cat. "There's no fire for miles."

"Don't you see it? The plume of smoke rising in the south?" The demon gestured vaguely in the direction he meant, where, true to his words, a thick column of smoke rose from the horizon. "Someone set that fire on purpose. I can't find it in me to care who...but there's a boy. He's survived."

The joy in his words made the reaper feel sick, and it took him a moment to find the words he wanted to say.

"This boy...he's going to summon you soon, isn't he?"

"He will be summoning a demon. I simply plan on being the first to answer. The boy will be an interesting adventure, his soul be damned. Quite literally." He chuckled and stood, grinning wickedly down at the reaper he'd known for quite some time. He wasn't surprised William hadn't foreseen this; no matter what they did in the privacy of a closed room, he was still a demon, and he would continue to be what he had to be in order to survive.

His gaze softened at the look of sadness in the reaper's usually cold eyes, and offered him a grim smile and held out his hand.

"Come on." William shook his head, mouth set in a stern frown. The demon sighed and wiggled his fingers at the reaper, bending at the waist to smile at him with those stupidly gorgeous eyes. "Come on Will, humor me."

William grumbled and grabbed hold of the demon's hand, ignoring the way the contact shot a wonderfully warm feeling through his entire body. He glared as the man pulled him into a close embrace, mouth brushing over his cheek in the most chaste way a demon of sin could.

"I won't change. I'm still the me you met all those years ago - but I am what I am, and I have to take this contract; it's just a little boy, any one else would take advantage of him. I can't let that happen, someone has to look out for the dogs after all."

"...I still don't like it. But...at least I know you still have a heart." The reaper finally smiled, albeit sadly, but a smile all the same. He leaned in to press their mouths together in a quick, nearly desperate kiss. The demons lips tasted like rain and sin. "Go. Be careful, I'm not the only grim reaper out tonight. Come back to me in one piece this time, got it?"

The demon didn't respond, he simply nodded once and let go, about to step off the roof and go to God knows where. He shot William one last glance, red eyes burning like miniature wildfires.

"I will return to you one day. I promise. Goodbye, William, until we meet under the light of the moon once again. Don't get into too much trouble without me before then."

"...goodbye demon...stay safe."

The next time William saw the demon that haunted his dreams, he was called Sebastian, he served a young boy filled with spite and hatred, he was threatening to kill his co-worker, he looked worse for wear, and still as regal as ever. But when that insufferable demon smiled at him, looked at him with those intense, red-as-wine eyes...

It was like that time on the rooftop all over again. The demon had truly kept his promise, although in an odd sort of way. When he mentioned this, Sebastian had laughed and William decided to shut him up in the kindest way possible - the demon's lips tasted like rain and sin.

But he hadn't expected that to change. His demon was his demon no matter what name he went by, or who he served or what he did...He just wished he hadn't kissed Sebastian in front of Grell and the boy. One was blushing and yelling at them to not ever do that again while the other was screeching for them to kiss again.

Oh, what a bother. Perhaps they should keep this behind closed doors.
