"No." Sebastian told the red headed reaper.

"Please?"

"Grell, the Demon said no." William T. Spears told his other half.

Grell folded his arms with a quiet "Humph."

"Why, in the name of Satan, would I dress up as a vampire?" Sebastian demanded through narrow eyes. "it would be utterly ridiculous."

"That's the point." Grell said with a sigh then he grinned. "lucky you have a husband that can make you agree to anything." he gave Sebastian a wink.

"Funny." Sebastian said sarcastically as William rolled his eyes at his lover. "Speaking off, have you seen Ciel? He left before I woke up this morning."

"Oh, he went shopping with Joe." Grell answered taking a sip of his coffee.

"He's not cheating on me, is he?" Sebastian joked half-heartedly.

Grell spat out his coffee as he choked, laughing all the while. "there's no way the little brat would cheat on you, Sebastian." Grell chuckled when he recovered.

Sebastian rolled his eyes. "oh, I know." he said in such a way that made Grell look at him with a cautious and suspicious gaze. "It's not like he'd be able to after last night."

Grell's yellowish green eyes widened as the infamous reaper caught on to what Sebastian was saying. "you Marked him?" he asked searching for an affirmative. "talk about finally." Grell continued when the elder nodded. "What took you so long?"

"I wanted to give him the freedom to walk away if that's what he wanted." Sebastian explained.

William frowned. "I do not believe I am familiar with the significance of 'Marking'." he said looking to the demon of the three for an explanation but it was his lover that answered.

"When a demon Marks another, they claim the other as their. . .not mate exactly because, well, Sebastian and Ciel can't exactly have kids, can they? But as close as a mate as you can get when you're. . ."

"We call them our Partners." Sebastian interrupted.

"Exactly," Grell agreed and continued. "once Marked, the Marked one is unable to have sex with anyone other than the person that Marked them but it only works if the Marked is willing to be Marked." Grell turned to his friend. "how did Ciel take it when you said he was yours? I mean, there must have been some reaction when you said 'Mine'. Don't look at me like that. Every demon does it. Now, what was our Lord's reaction?" Sebastian blushed and muttered something. "So we can hear you." Grell snapped impatiently.

"He. . .well, he asked me to. . .show him how much I own him and then, at the end, he. . .said. . ." Sebastian was bright red by this point. "he said 'Always'."

SMASH

Grell had dropped his coffee mug and was now staring at the elder with wide, startle and joyful eyes. "he didn't try and say you were his too? He just let you claim him? No struggle for domination? Just 'Always'?" Sebastian nodded and Grell burst into jubilant tears. "oh, My. This is like one of those predictable love stories. It's almost like. . .like. . .Twilight!"

Sebastian let out a growl. He hated those films with a vengeance.

"The books, Sebastian, the books." Grell reassured the demon, knowing the elder thought the books were alright (yes, it surprised Grell too). "Oh, this is wonderful."

"What is?" William demanded, completely lost. "How is that of any significance?"

"Oh, Willy." Grell giggled "It's been centuries since any demon, once human or once angel alike, have been so submissive when being Marked."

"So?"

"Submissiveness does not come naturally to demons and kings."

"Which mean. . . ?" William prompted as Sebastian became a deep shade of scarlet.

"Which means" Grell was rather annoyed by this point since William, who was meant to be a very intelligent reaper, was obviously not getting it "the Demon king has found his other half."

William's eyes became very round. "you mean. . ."

"Yep."

"After all this time?"

"I know."

"So. . ."

"Our little Phoenix has found his Soul Mate."

Ciel snorted as he spotted an outfit that was just begging to be inspected. "Oh, the irony." he muttered as he touched the frilly white lace. He glanced at his two companions and grinned. "Charlotte, Joe. I think I've found the perfect outfit."

The bambi-eyed brunette female demon released her Partner's arm to inspect the article of clothing Ciel was currently grinning at. "It's perfect." she said with a wicked glint in her eyes. "We just need to get you a couple of things to go with it and you'll be the hottest damned thing at this ball."

"Hey!" Joe protested teasingly.

Charlotte rolled her eyes.

Ciel sniggered, grabbed the white thing and rushed down a different isle to find the required items to go with it.

Sebastian waited patiently for his other half to come home. It was around six that evening when Ciel returned with bags in his hands.

"No peeking." Ciel said and rushed off to some part of the mansion that Sebastian wasn't likely to go. He hid his purchases in a room that was the exact replica of his parents'. He mentally apologised then rushed back to his lover's awaiting arms. "how was your day?"

Sebastian smiled and pulled Ciel onto his lap when he had sat himself back down on the sofa. "Uneventful. I was stuck with Grell and his poor excuse for a lover. I thought it was bad when he was dating the Undertaker."

Ciel blinked. "Grell dated Undertaker?"

"Uh-huh ." Sebastian said with a yawn. "For a little while. Maybe a decade?"

"Huh." Ciel commented before snuggling further into Sebastian's embrace. A thought occurred to him and he decided to ask Sebastian about it. "Sebastian, why did I stop aging at eighteen? Why didn't I just stop when I became a demon?"

Sebastian smiled. "Because you hadn't reached adulthood yet. Your gorgeous little body was too hormonal and underdeveloped to stop growing." the elder explained.

"Then why am I so short?" Ciel said with a cute pout that had Sebastian laughing when he saw it.

"That's just you." Sebastian said brushing his nose against Ciel's. "You're so itty and bitty because that's just you. Besides, it would be cruel to have you any taller. How on earth would I find some excuse to fuss over you if you weren't so small?" he laughed at Ciel's dark glare. "You love it really."

"Humph." was the response as Ciel crossed his arms and Sebastian just nipped playfully on his ear. Ciel turned his head and kissed the elder softly before snuggling back into his lover. "I'm tired."

Sebastian tightened his hold on his young love and stood. He carried his master to bed were they each fell fast asleep before their heads hit the pillow. Or Sebastian's chest as was the case with Ciel.
