And so we've reached the end... Of this story anyways, but I'm a slut for fluff so I'll definitely make some one-shots for this AU later. Thank you guys SOOOOO much for reading, commenting, and leaving kudos; it motivated me to keep writing and updating as quickly as possible and still makes me extremely happy to read over whenever I'm feeling unmotivated, upset, or uninspired! It's been a great help to me and I truly don't deserve it! Without further ado though, here's the overly fluffy ending!

Edit: To answer your question Dardar1 (I couldn't reply as you didn't comment from an account). Yes, Sebastian still plans to change Ciel into a demon, but he wanted to wait until their children were a little older. Since he would be a newly changed demon, Sebastian would have to teach Ciel to control his powers and devour souls, which would be too overwhelming alongside caring for newborns. He will definitely be made immortal though, Sebastian would never chance losing him now. 3

Chapter song: Look After You - The Fray

A year ago, it would have been alarming to wake to the sound of crying. Save for his heats and the day he was summomed, Sebastian had never heard Ciel cry. On the occasion that he had a nightmare, tears would fall, but not a single sob would pass the boy's trembling lips. Likewise, Ciel had seen Sebastian shed tears only once - on the day that their twins were born. Since that day, the manor has scarcely been silent since. It seems that sometimes that is the case even at night, the alpha mused as he propped up on his elbows, watching Ciel stir at the wails echoing from the room opposite of theirs. The earl groaned, groggily sitting up with a firm hand on the mattress keeping him from falling back into the welcoming embrace of their bed. Winter was growing colder already though it was only three days into the season. "Ciel, go back to sleep, I'll take care of the pups," Sebastian soothed with a hand settling upon his lover's back, barely catching the disquieted whine he released in response to their children's unhappiness. "No, I'm already awake now. I can't go back to sleep with them upset. You take one and I'll take the other?"

Noting the hint of frustration and weariness lingering in the omega's tone, Sebastian crooned quietly, lips delicately grazing Ciel's left temple before he stood. "Of course. I shall procure their bottles as well." At three months old, their pups had quite the set of lungs on them; it was a wonder the servants downstairs managed to get anymore sleep than the bonded pair upstairs. Sebastian was beginning to reconsider the idea of placing their cribs in their bedroom rather than the nursery, at least if they were in the same room, they could merely cross the floor to comfort their babes. At first, they had attempted to swap out who cared for the twins at night, allowing at least one of them to catch a good night's rest, but it simply wasn't possible. Naturally attuned to the cries of his young, Ciel awoke the second a peep left one of the children no matter how quickly Sebastian managed to quiet them. And while Sebastian too jerked into consciousness upon hearing the sobs of his distressed pups, he would wake even sooner if he felt Ciel shift from the bed. But as it was, the pups had been increasingly rambunctious the last two nights after coming down with a mild fever.

Their temperature, while barely above average, had sent Ciel into a frenzy, rapidly building a large enough nest for their entire family and staying up all night to watch over them anxiously alongside his mate, who tried his best to encourage him to sleep while he kept them safe. It was the first time their offspring had fallen ill since birth and the stress of it had earned him an extremely testy omega and two whining children the morning after their fever had broken. The aftermath hadn't yet blown over completely and all he could do was comply with Ciel's wishes to save both of them the trouble of discussions an hour passed midnight. They both desperately needed sleep. "No, wait until we check on them first. They were changed and fed just an hour ago." Encouraging the nobleman to slip on his navy robe, Sebastian leaned down to tie it at his lithe waist, ignoring the eyeroll he got in return. "Must you fuss over me so much? I will hardly catch a chill from walking across the hall." With a smile and a bare hand nudging the smaller male to the door, Sebastian spoke sweetly, "Be that as it may, I don't wish to chance it. You are terribly fatigued as it is and that would only be made worse by sickness. Now come, let us care for the children."

Stepping into the ivory nursery with steps more quiet than the sound of a feather falling, Ciel rushed to the crib on the left while Sebastian approached the right. Gathering his tiny newborn son into his arms, Ciel frowned at the tears streaking his florid cheeks, shushing him while cupping his hand against the back of his head. "Shh... Calm down, Corvin. You aren't alone now, I'm here. I have you now. You have nothing to fear. Just close your eyes, baby." The nerve-fraying sobs didn't cease however, they only grew in strength as the child's hands came to weakly knead at his plush robe, his face pressed against his bearer's shoulder. Growing more perturbed with each minute that passed without his youngest calming, the omega gathered a bottle - the milk was denied. In a new attempt at settling the poor child, he changed him and checked his temperature, finding nothing to truly be amiss. Still, Ciel could feel his own panic rising as he turned from his sable and navy haired son to his mate, chewing his lip raw. His eyes were starting to feel watery, like the first mist before a strong storm, and his voice as shaky as the one he spoke in when shivering from the cold - he internally cursed his nature for getting in the way of his rational thinking. "S-Sebastian, there's something wrong. He won't calm down no matter what I do... Is he ill? Is it something I've done?"

While cradling his baby girl close to his chest, Sebastian cooed to her softly, kissing her plump, strawberry pink cheeks as he bounced her softly. "There, there, darling Elpis. Whatever is troubling you so late, hm? You're safe here, no harm will come to you. Dry those eyes, little princess," The alpha cooed, pacing slowly in hopes of soothing her back into a peaceful sleep with the swaying movements, vaguely mimicking the drift of grass in an emerald meadow. His plan, while being the one he always turned to, didn't fail to succeed; the young, half-demon girl fell asleep in seconds flat. Her body curled instinctively closer to her father's, garnering as much heat as possible from the larger body as he rocked her to prevent her from waking. A quick glance toward his lover proved that he wasn't fairing so well.

The alpha was as new to this as Ciel, and yet he sometimes took these late-night wakings far better than his other half. Corvin was notorious for his finicky behavior when it came to sleep and attention, craving a loving presence at all hours of the day and night. While Elpis still craved care and adoration, and like any newborn was prone to crying at night, she was far less reliant on her parents' presence during slumber even on her bad days. While accepting that all children had different habits, Ciel struggled to cope with Corvin's prolonged cries, seeing it as a personal failure when he didn't calm him by the time his daughter was asleep. His own emotions got the better of him during those times, particularly when he was sleep deprived and fretting anyways. Between the demands of their children, the large stack of letters requiring his attention, his letter to the queen regarding the details of the most recent case he'd solved, and the winter gala coming up in a week, he was both tired and irritable. And while Sebastian did his best to help his mate manage all of the work piling up, he too was juggling more tasks than usual with their newest additions. Fires needed to be stoked more often with the coming of winter, new recipes were to be learned to stave off the cold as well as give his master more energy, the bedsheets needed to be changed to warmer, heavier materials, and Ciel's new coat was yet to be retrieved from the tailor. But, despite the extra workload, neither could bring themselves to regret having pups. They were worth losing a few hours of sleep for.

"Ciel, bring him here and I'll try to help," Sebastian suggested, warily eyeing his floundering mate. Slowly stepping forward, Ciel offered the alpha the youngest pup, taking Elpis from his arms with a wobbling bottom lip. Holding his daughter lovingly, he nuzzled against her short strands of slate hair, the tips beginning to turn black with her growth. He bit back his disappointment with himself and focused on her instead. She was still so very young, but he could already tell she would be an alpha when she was grown. She had a strong gaze and while only three months old, she wasn't as slight as her brother, who held a build more similar to the one Ciel had at his age; She would be extremely protective over Corvin someday. Though her colouring was similar to his, her features greatly favoured his mate. She was beautiful, both pups were, and he loved them dearly - he had since the day he found out he was pregnant.

Bleary eyes of azul and heliotrope raised and traced over Sebastian's form, watching him sway back and forth, slowly but surely lulling their son back into a peaceful rest. "There, there, Corvin... Sleep now, you're perfectly safe here." Brushing back navy-highlighted raven hair, the alpha kissed his son's forehead, shushing his whimpers with the subdued hum of a lullaby. Looking to his lover who watched on with a sense of longing, Sebastian offered a sad smile and strode across the space between them until they stood face to face. Pressing their foreheads together, Sebastian spoke, "Ciel, it's okay... Corvin takes awhile to calm sometimes, it's nothing you've done. He loves you very much, darling, he just gets upset if he doesn't manage to sleep all night."

Closing his eyes, Ciel denied his words, becoming increasingly unsettled by his inability to comfort his pup. His voice wavered unstably and he cleared his throat to strengthen his words, "I'm not a good father, I can't even soothe my own child. I'm trying, I truly am, but... I don't know what else I can do for him. He wasn't hungry, he didn't need a change, he isn't feverish. He doesn't feel protected with me and I don't know why... I try to make my scent stronger but even that doesn't help him like it does for Elpis." Sniffling quietly and bowing his head to hide his twitching nose, he watched Corvin sleep peacefully, willing a whimper to stop bubbling up in his throat before it had a chance to escape. It was so easy for Sebastian, he was the best alpha and father Ciel could have imagined; Yet what should have been instinctual to himself was a task he couldn't fully manage.

"It isn't that he doesn't feel safe, but I think I may know what it is... As an alpha, I produce more body heat than you do, which helps him fall asleep sooner as he's rather small and unable to fully regulate his temperature yet. Omegas have lower temperatures naturally, but you also have a stronger scent, which will soothe them faster than even I could. You just need to press his head closer to your neck so he can be surrounded by your scent. You need to calm down first though, okay? He can sense your emotions, love. You're tired and upset and he feels that. He doesn't like for his father to be unwell." One-handedly, he caressed Ciel's cheek, purring softly to cheer the other up. After several long moments, he was answered with a purr an octave higher than his own. "There we go... Here, swap one more time, you'll see. If he didn't feel safe with you, he would cry the moment you pick him up."

Holding Corvin once more, the earl sheltered him against his shoulder, feeling the faint prod of the pup's twitching nose beneath his scent gland. The child cooed quietly, latching onto his shirt with a tiny fist, holding as tightly as he was capable of. With a relieved smile rising to his lips, Ciel kissed his wispy hair tenderly, "My little prince..." Sebastian offered a fang-filled grin, guise slipping the slightest bit in his joy, watching his mate press his lips to their daughter's forehead next. "See, Ciel? He loves you too, as does Elpis. You just have to use a different technique than with the her."

"Sebastian." The onyx-haired demon canted his head, listening carefully to his lover's voice, relieved to find that it was no longer trembling with nerves or anguish. "Thank you. I know I overreact to these things sometimes, and for that I apologize, but thank you for helping me and for not giving up on me. I'm trying to stop worrying so much but I still need to work on it. I've never had to care for another before; it scares me not knowing what's wrong when they cry," The aristocrat admitted, eyes set on the faint moonlight creeping in through the gap in the drapes.

Nuzzling his nape, Sebastian darted his lips below the downy hairs dusting his neck. "Don't thank me for simply caring, Ciel... And know that I blame you for none of your actions; fearing for their health, happiness, and safety is nothing abnormal, it is part of being a parent. And it makes you a good one, you care for our pups, that cannot be said for everyone." Propping his chin on the narrow shoulder of his omega, Sebastian crooned, moving to Ciel's side so both could see the pair of twins. "They're precious though, aren't they? Corvin has your nose." Lips curling warmly, Ciel tilted his head to brush his mouth over Sebastian's. "They're perfect. And Elpis has your eyes. They may be the shade of mine but they are the shape of yours. Somedays, I still cannot believe they are here with us." Returning the peck with a prolonged lock of lips, the older demon felt his smile expand when a quiet chirp left his other half. "Nor can I. But I'm glad they are. Now that they are asleep again though, I think it is time we return to our own bed. While I may indulge in it when I am beside you, I do not require sleep. You on the other hand do, and have already lost so much of it as it is." Urging Ciel towards Corvin's crib, the alpha came to a halt when the omega stopped a few feet away. Mismatched eyes flickered from his path to their daughter in contemplation. "Could they sleep between us tonight? So we're there if they need us again?" Burning amaranth irises softened, thoughtfully remaining on his family. How could he deny him? "If that's what you want, then of course, love."

Returning to their bedroom with their children still held lovingly in their arms, they delicately placed them in the center of the bed. Taking their respective sides, both curled around their brood, fondly watching them nap. Above the pups' heads, the two lovers' arms stretched atop the pillows, fingers interlocked, and thumbs tenderly massaging their mate's hand. They stopped only when the mortal's eyes began to droop, lashes flirting with his cheeks in a valiant fight to remain awake and alert. Chuckling, Sebastian squeezed his palm and leaned over the children to steal a sweet kiss. "Sleep, Ciel, you're going to need it tomorrow. You can see the pups in the morning. I love you, dearest." He trilled, watching the glow of the eyes he so adored be completely masked by his thick, midnight lashes. "I love you too, Sebastian."

It was hard sometimes, managing daily tasks, social functions, and children all while helping Ciel - and himself for that matter - remain in a tired semblance of a good mood, but the alpha could tell it would get easier with time. The pups would grow and require less care someday, they would be capable of doing more things on their own and genuinely learn about this world while standing on their own two legs rather than being carried everywhere. Though if his hunch proved to be correct, they wouldn't stray far from his or Ciel's arms anyways. His mate would cling to their babies as they grew up, that much he knew from his behavior now, but staring down at the enchanting sight before him, he couldn't say he would not do the same. But that was a long way off, the pups wouldn't be fully grown half-demons for many years yet, and until that day and long after, it was going to be quite the adventure. He couldn't wait to see what new challenges and surprises tomorrow would bring. With an unwavering sense of contentment - no, happiness - Sebastian fell asleep, the moonlight shining brightly and his family safe in his arms.
