A/N: Alright! So this is the first Kuroshitsuji fanfiction I'm officially posting! As I said, it updates WEEKLY every Sunday night, and I aim to be incontrovertibly punctual xD I can remain firm in my claim because much of it is already written, and this will be finished! Though it will mention this later, the story begins about a year after Season 2 ends, and follows the EXACT canon of the anime only. Anyhow... I don't know why I started an author's note, because I have very little to say... but I hope you enjoy. Please review!

I've collected a variety of songs for this fanfiction and this ship, and so there will be a playlist per chapter! Abundant gratitude to the ever-lovely 3iluvsonic4ever27, who helped me organize the songs for the playlist! (Lord knows I'm too disorganized to do anything myself xD)

Chapter 1 Songs:

Blinding- Florence and the Machine

Lacrimosa- Kalafina

Si Deus Me Relinquit- Konishi Kayo, composed by Iwasaki

Warning: In later chapters, there will be explicit sexual content between demons involving an underage boy and an older man. However, considering that you knowingly clicked on an M-rated romance-genre Sebastian/Ciel fanfic, you really ought to expect this. xD

Disclaimer: Believe it or not, I didn't wake up this morning as Yana Toboso, so therefore I don't own Kuroshitsuji or its characters.

Chapter 1:

For an instant, he had tasted it.

Trickling in a single stray bead of blood, it had dribbled over his alabaster lips. The flavor was muddled by the characteristic salt and rust and toil, but it was still there. The taste of Ciel's soul.

A flick of the tongue, and it was gone, the remnants all but inconspicuous in his mouth, but he recognized it. How could he not know it? He could constantly feel and smell it when Ciel was human, practically emanating from his form, enriching his thrumming blood like adrenaline and palpitating through his veins. A soul so pure, fine, and immeasurable in value, even a sample could tempt a demon into madness. He had watched it happen before, with Claude's pining, desperate effort, and it killed him. It was the unique, taunting soul he had coveted and protected for so long in a way that was nearly… eudemon. When it was locked away forever, he had no hope of coming into contact with it again. Yet here it was, without explanation…

"Sebastian!" the irritated bark of his young demon master stirred him from his thoughts. "Sebastian, what's wrong with you?"

The bitter tone stultified whatever sensation stilled him before, and as he left his stupor, familiarity returned his senses. He met a cerulean eye, which gave him a fierce yet none-too-impassioned gaze. Ah, if any evidence remains of my master's soul, it is in his personality. Though outwardly colder and cunning, he had not changed maliciously as a demon, and Sebastian could not decide if he was grateful for it. For, while Sebastian did find Ciel's company pleasant and agreeable, if in a masochistic way, his presence was a tease. A pesky mockery of the soul and freedom he had lost. Now, as they were shackled for eternity, he would have to endure it forever. In addition, he didn't know if the reason his master kept him around resulted from a sadistic impulse on a demon-spurred impetus, or if it was emotional attachment, from that latent soul. This wouldn't mean it was an affectionate bond on Ciel's side; no, just one of habit.

"Well?" the master blinked; his little muscles were tensed, as if prepared to strike, but it was a gentle, childish bluff; Sebastian knew Ciel would only ever hit him if he had done wrong. He was not pernicious. The dour expression on the older demon's countenance softened into a rare smile.

"Forgive me. You have blood on your face, my lord. It is slightly unbecoming," he purred liltingly.

He looked at the near-fatal wound on Ciel's forehead, not even bothering to survey the wreckage or debris that caused it, and knew that a year ago, it would've terrified him. However, now, the injury had already healed, leaving a dark wet crimson in its wake. A nostalgic twinge of protectiveness wrenched in his gut at his instinct, but he choked it down.

The blood, he thought. It will cake and congeal if left to dry, and that flavor will go to waste… I just need to assure it was what I thought it was…

Ciel's sour expression lightened a bit. Sebastian took the opportunity to remove his glove and tenderly wipe the red mess from his face, as if it was the most natural thing in the world. Flustered at being babied, even when their relationship had grown so unusual, Ciel grunted in protest and swatted at the advance. He then swiveled on his heels and straightened his coat, insolent as ever, despite that his dark blue hair was matted with mahogany and plastered to his forehead. Sebastian almost wanted to chuckle at his lord's appearance, but let the earl do as he pleased. As soon as Ciel's back was turned, Sebastian stared at his blood-dabbed fingertips with awe; he couldn't remember the last time he had felt so invigorated over a discovery. Warily, he lifted them to his lips.

This is it. The first time he hadn't deceived himself. That rich, enthralling taste that could only belong to Ciel Phantomhive, who in turn belonged to him. But… how was it possible? Ciel "died", so his soul's tangibility should have been extinguished with him. It had never happened since the transformation, and it shouldn't be happening, but Ciel was no regular demon, after all. Neither was Sebastian.

Ciel turned again when he realized he was not being followed, and was startled to see Sebastian savoring his blood, ravaging his own fingers with an eager, meticulous tongue. Ciel crinkled his nose and sniffed, but opted not to comment on the oddity. He found it curious at first that Sebastian would remove his gloves to touch him. However, now the way the demon looked at him was making him apprehensive. Instead, all he said was, "Sebastian, we're leaving. Take me out of here. That's an order."

Withdrawing his fingers from his lips, careful not to salivate, he slipped his silken glove back on and placed his hand on his chest in a humble bow. "Yes, my lord." All of the young master's tedious orders. Still sore over the turn of events, each demand made him simmer with traitorous regret. However, simultaneously, he was thronged with a powerful devotion he couldn't explain. Must just be the contract. Yes, he and his master were bound irrevocably and irreversibly, by contract and complexity. Their fates were intertwined, woven to the point that they were impossible to disentangle. Though the smarting frustration of Sebastian's entitlement ebbed with time, he was uncertain if Ciel's soul would change that, and more confused over how he'd feel about it.

No, I must consult someone about this, Sebastian resolved with clarity. Someone who understands not only what awaits beyond the grave, but the young master as well. Sebastian was mildly appalled that he understood both himself, but couldn't figure it out.

Triggered by loyalty, Sebastian leaned over and bundled up the earl's lithe frame in his arms. He noted with interest how Ciel willingly wrapped his arms about his neck. What bothered Sebastian more, as he watched his master's milk-white cheek press softly into the lapels of his midnight jacket, was the fond attachment he still had to the boy, even though he had been wronged, trapped, and had nothing to gain.

Better to get this soul issue resolved quickly, if he still owes me what I'm due.

With a hasty bound, the pair was gone, leaving remnants of disaster and carnage in their wake.

A/N: The first chapter is really more of a preface or prologue... so I uploaded the second chapter with it. :) Two chapters in one update, whoohoo! x)
