Work Text:
Ciel stood in front of the mirror in his dressing room.
He had sent Sebastian away to make sure their guests were settled for the evening, his hope being that the demon wouldn't think anything of the fact that he wanted to bathe and dress himself for bed that night.
Elizabeth had insisted on hosting a Christmas Eve party with a lavish miniature ball and inviting Soma, Sieglinde, their manservants and the Phantomhive staff as guests. Tanaka and Sebastian asserted that they would serve them while the rest took a night off to celebrate. Ciel truly didn't mind. They all worked hard enough— when they weren't destroying the manor— and it made Lizzie happy to throw a party. She was even more excited when she had learned that Soma, Agni and Sieglinde had never celebrated Christmas before and was adamant they attend under the premise of showing them the “best Christmas ever.”
Ciel smiled fondly.
He wasn't much for parties, but seeing those around him enjoy something small and festive was satisfying in its own right. Sebastian had been busy all night entertaining the rambunctious Lizzie and Soma, which left Ciel with more than enough time to slip away to meet with Sieglinde for the first part of his plan for the evening…
He approached Sieglinde nervously weeks before for advice. She was one of the only ones truly aware of his and Sebastian's secret relationship and— to Ciel's bewilderment— had been especially enthusiastic with her support.
What does one give their lover who has no use for worldly possessions?
Sieglinde's enthusiasm had led Ciel to a secret visit with Nina to acquire an enticing ensemble for him to wear for Sebastian.
Which is what finally led him to this moment; nervously shifting the sheer fabric and lace around his body as he took in his appearance in the mirror.
The lingerie was a deep, royal blue meant to accent his eyes and stand out against his pale skin. The sheer lace of the loose-fitting brassiere did nothing to hide his pert nipples, and— coupled with the lace garter belt, stockings and revealing panties— Ciel was sure it would drive his demon wild. What better gift to an immortal creature who did not desire any physical belongings, than a night of unrestrained passion?
It would be a shame for the pretty lace to be torn and ruined, but it was a sacrifice Ciel was willing to make for Sebastian. The boy flushed at the silly thought and busied himself with tying a matching ribbon around his throat. He smoothed his hair out of his eyes, deciding to forgo his usual eyepatch for the evening. It wasn't necessary and Ciel knew perfectly well how much Sebastian liked seeing the mark of their contract.
With one final glance in the mirror, Ciel determined he was as ready as he could be. He grabbed the flowing robe and wrapped it around himself as he went back into the bedroom. As he climbed up onto his bed he froze for a moment. It had been months since they had been intimate, between work for the queen and Ciel's responsibility as an earl. He had never given it much though before but… what if the demon had grown tired of him? What if this distance that had been formed between them hadn't just been because of their duties, but because the demon had grown bored? What if—
A knock on the door interrupted the thought.
“Enter,” Ciel beckoned in a small voice, nerves overtaking him.
“My Lord, your guests have been attended to as you wished. I have come to see—” Sebastian stopped when he caught sight of Ciel on the bed, silk fabric sliding down one shoulder. The demon grinned, eyes aglow with hellfire. “My, my, now what would be the occasion for such compelling attire, young master?”
“I-It's your gift. All of the Phantomhive staff were given Christmas gifts. This is yours,” Ciel said, chin raised in a haughty expression— feigning confidence he hoped the demon wouldn't see through. “You have my permission to do whatever you wish to me.”
“Oh?”
Ciel narrowed his eyes. “Within reason.”
The demon chuckled. “I certainly hope you weren't this generous with the other servants.”
“Don't be perverse!” Ciel snapped. “You know it's only you.”
Sebastian's smile softened and he approached the bed. “I certainly am lucky then, to be given such a generous gift.”
Sebastian ran one hand up Ciel's shoulder to cup his face tenderly, the other caressing over Ciel's chest to push the robe off his shoulders. The kiss wasn't sudden or unexpected, but Ciel still felt a jolt of heat shoot through his body when the demon's lips pressed to his nonetheless.
“You look lovely, my lord. There was no need to be so nervous now, hm?”
Sebastian's gloved hand slid up Ciel's thigh, smoothing the lace against his skin. Ciel's smaller hand caught the demon's.
“Wait. You- I want you to remove the gloves,” Ciel murmured, cheeks aflame.
The demon only grinned in response, slowly pulling the cotton gloves from his hands with his teeth. After all this time Ciel knew it was a tease, but his stomach still flipped at the sight.
Insufferable demon.
With the gloves removed Sebastian placed his bare hands back to Ciel's thighs. One thumb ran along the lace pressed against his skin. The boy couldn't help but shiver at the contact.
“The coat next. And your vest.”
“My gloves and my coat? Are we feeling adventurous today, sir?”
“I- I just thought maybe you would appreciate it… As your gift.”
Thus far, every time they had been intimate Ciel insisted the demon remain clothed during the act. Removing Sebastian's gloves had been as far as he was ever willing to go. Ciel would never admit out loud that he had been fantasizing about undressing the demon for months and longed to feel Sebastian's skin against his.
Sebastian smirked and stood from the bed. He shrugged off his tailcoat and draped it across the chaise, his vest and tie following suit. When he climbed back up onto the bed, he bracketed Ciel's smaller body with his own, pressing a kiss to the boy's lips.
“I'm very fortunate I have such a generous master.”
Ciel rolled his eyes, but allowed the demon to press him down onto the bed, hands caressing along Ciel's body. Fingers sliding underneath the silk to tease his sensitive skin as Sebastian's mouth traveled down Ciel's chest, pulling the sheer fabric aside and running his tongue across a pert nipple. Ciel couldn't help but gasp, gripping Sebastian's shirt tighter, grounding himself.
He never thought he would be to be able to share any moments of intimacy like this. The revulsion he felt when anyone other than the demon touched him had become the norm. Truthfully, he expected to feel the same disgust and horror the first time he requested Sebastian share his bed, but something was different. He not only felt at ease with Sebastian's touch, he grew to crave it.
So now— as Sebastian kissed and caressed along any bare skin he could reach— Ciel melted into the bed. He would never admit out loud how much he had missed this.
Feeling worshipped.
Cherished.
A secret he would never reveal to another living soul.
“If I didn't know any better, I would think you missed me,” Ciel teased.
“I long for you every moment I'm not inside you.”
“Beast.”
Sebastian grinned, fangs bared and eyes aflame. Ciel couldn't help but shudder when Sebastian pressed his lips once more to his neck. He didn't even care that the demon was leaving love bites in his wake.
Ciel wrapped one arm over Sebastian's shoulders, the other gripping the sheets beneath them. The demon's free hand slid lower, teasing across the lace of the panties, ghosting over Ciel's straining cock and finally stopping to grip the silk covered ass. Pulling the fabric aside, Sebastian eased a finger between Ciel's cheeks, finding the hidden pucker of his hole. With a gentle kiss to Ciel's forehead, Sebastian slid his first finger in to the knuckle.
When he began to ease out and thrust in with a second finger Ciel caught him. “I- I already prepared myself. You don't have to-"
“I would still like to, if I may,” Sebastian murmured.
“If you wan- ah!” Ciel cried out as Sebastian pressed back in with two fingers.
“Mm, it seems I found it, didn't I?”
Ciel could only moan in response, a wave of pleasure washing over his body, back arching as Sebastian massaged that spot.
“O-oh God. Sebastian! Wait— Stop! I don't want to come yet!” Ciel let out a shuddering breath when Sebastian ceased his assault and removed his fingers. He looked back up to the demon, eyes unfocused. “I want you inside me.”
“As you wish,” Sebastian murmured.
The demon repositioned Ciel, laying him back against the pillows with a quick kiss to his lips. When he tried to pull away Ciel grabbed his shirt and pulled him back down, sliding his tongue into the demon’s mouth as he fumbled with the shirt's tiny buttons. Sebastian purred in response, tugging Ciel’s panties down over his legs and tossing them to the side. Ciel couldn’t wait any longer; he undid Sebastian’s trousers, freeing the demon’s cock, who shivered in response. Ciel’s lips quirked up into a playful smirk as he took Sebastian’s cock into his hand, offering a tentative stroke.
Ciel fully expected the demon to devour him, but instead he cradled him close, hands gently roving up and down Ciel’s body reverently as he settled between his trembling thighs.
“Master…” Sebastian moaned into Ciel’s shoulder, leaving a gentle kiss on the side of his neck. “I could never grow tired of you, my soul.”
Ciel flushed and swallowed hard. How could the demon have possibly known what he was thinking before entering the room?
“How…?” Ciel breathed, face turned away. Whether he was afraid to see Sebastian’s expression— or he wanted to keep Sebastian from seeing his— Ciel was unsure.
Sebastian turned Ciel’s face gently towards his, a soft finger caressing down the apple of his cheek. He said nothing, but his expression told volumes. Of course he knew Ciel was doubting himself. The demon knew him better than anyone on this earth; their souls entwined for all eternity.
“I'm not made of glass,” Ciel protested halfheartedly.
“One should treat the things they deem precious with care, should they not?” Sebastian replied, not a single hint of mockery in his voice.
“D-Don't say such foolish things…” Ciel flushed and tore his gaze away from Sebastian's once again. The demon claiming he was precious? What utter nonsense.
But the thought made Ciel's heart race.
Ciel gripped Sebastian's shirt as the demon lined himself up, breath caught in his throat. Sebastian pushed in slowly, soft words of encouragement murmured against Ciel's forehead as the boy keened.
With a shudder Sebastian froze, lips pressed to Ciel’s forehead. Ciel knew it was to let his smaller body adjust, but he needed this. He needed the demon to move. To fuck him until he couldn’t remember his name. This gentleness was just too much.
“I-I'm doing this for your pleasure. Don't worry about mine…” Ciel breathed, hoping Sebastian wouldn't comment on the desperation in his voice.
“I cannot do that, Master. Your pleasure is my pleasure.”
Ciel groaned in frustration, hitting Sebastian’s chest with a balled-up fist. “Why?! Why do you insist on being so gentle?! I don’t need it! I’m not a fragile thing that needs to be treated as if it’s breakable!”
Sebastian caught Ciel’s fist, pinning it against the bed. “To the contrary, I do not believe you are fragile, nor am I treating you as such. You told me that I could have my way with you, did you not?”
Ciel scowled, ignoring the fact that Sebastian’s cock was half buried in his ass, and that he was flushed and breathing heavily. He would not tolerate the damn demon telling him such ridiculous half truths.
“Master?”
“Fine! Yes! I told you that!” Ciel snapped.
“Then why can I not make love to you gently?”
Ciel nearly choked at the phrase ‘make love,’ and sputtered at the demon.
He closed his eyes and laid his head back, taking a deep breath. This wasn't something he wanted to explore ever, and especially not when he was practically naked with a man's cock inside him. But he knew the damned demon was like a dog with a bone, and would never drop the subject until he was satisfied with the answer.
“I don’t deserve it.”
“You believe you deserve a lifetime of suffering,” Sebastian breathed into Ciel's ear, pressing himself further into the boy's body. “However I am here to serve you and your every need. Not be your tormentor.”
Ciel gasped as Sebastian bottomed out, back arched. How could he forget how big the damned demon was every time?
“So lovely,” Sebastian murmured, a gentle finger caressing Ciel's flushed cheek.
“Just move,” Ciel whined, thumping Sebastian's chest once more with his free hand.
Sebastian caught that hand too, pulling it up to be pressed into the mattress with Ciel's other pinned arm. Ciel shuddered and gave a half-hearted tug to free his arms, but the demon didn’t budge.
“So impatient.”
The demon kissed Ciel's trapped hands, one finger at a time. A gentle brush of the lips to his palms before Sebastian shifted to press another to the lobe of Ciel's ear, running his tongue over the sapphire stud and up the shell of his ear. Ciel couldn't help but shudder.
“Sebastian… please…”
Ciel didn't expect the demon to listen to his pathetic whining, but he shifted, pulling partially out before thrusting back in with a slow roll of his hips. His pace was steady, but infuriatingly gentle with murmured words of affection breathed into Ciel's ear. He bit his lip to stifle the whimper that squirmed in his chest, an uncomfortable warmth that begged to be free. Ciel pushed it down and away.
It was embarrassing enough his cock was the hardest it'd ever been in his life. Throbbing and making a mess of his belly while it went ignored.
“My beautiful master,” Sebastian murmured, brushing the hair from Ciel's forehead.
“Don’t.”
“Don't what? Call you beautiful?” The demon asked as he ran a thumb across Ciel's bottom lip. “But I took a vow that I would never lie to you, my lord. And right now you are a sight to behold. Cheeks flushed, eyes filled with desire, chest heaving with your pleasure.”
Sebastian shifted, hitching up Ciel's leg and rolled his hips once more, cock hitting just the right spot to make Ciel see stars. He couldn't help but moan, choking out Sebastian's name. Pleading for more.
“You have such a lovely singing voice, Master. Those sweet, gasping breaths.”
“J-Just shut up and don't stop, you insufferable demon!”
“Yes, my lord,” Sebastian cooed, thrusting forward once more.
Ciel felt his peak approaching sooner than he wished, with no indication that the demon was even close.
“S-Sebastian,” Ciel groaned, back arching. “I’m-- ah! I’m close!”
“Lose yourself to the pleasure, master.”
“I-I can't! Not until you do!” Ciel protested.
“You know I will follow. Always,” Sebastian purred in Ciel's ear.
Ciel trembled, fingers digging into Sebastian's hand where it held both of his, as he fought. He didn't want it. Not like this. With Sebastian's whispered words of adoration and devotion in his ear and the demon making love to him so tenderly.
The gentle brush of lips at his throat was what undid him. The orgasm tore through Ciel with a cry as he came over his own belly and Sebastian's open shirt. The demon wasted no time, losing his own rhythm and coming with a groan only moments after.
Ciel's entire body quaked, but his mind was too caught in a fog to consider why. Vaguely he was aware of the demon's cock softening inside him and Sebastian's warm hands massaging his slender wrists lightly. Ciel closed his eyes, just for a moment. He would tell Sebastian to clean the mess in just a moment…
Ciel blinked his eyes open. “Huh?”
“There you are, my lord. I was beginning to wonder if I had left you comatose,” Sebastian teased.
Ciel scowled in response.
Sebastian chuckled. He had cleaned the two of them up; dressing Ciel in his nightshirt while he had been unaware. The demon's trousers and shirt buttoned neatly, but his vest and coat were still set aside.
“Now, now. No pouting, my lord.”
“I'm not pouting. I'm not a child.”
“Indeed.”
Ciel watched as Sebastian tidied up the few articles of clothing that had been cast aside when he had been undressed. But when the demon reached for his own coat, he felt a spark of panic.
“Wait!”
“My lord?”
“I- Will- I would like you to stay.”
“Do you wish for me to stand by the window?”
“No!” Ciel caught himself, wringing the hem of his nightshirt between his fingers. The thought of the demon leaving him made his chest feel empty. “N-No. I would like you to share the bed with me.”
Sebastian's lips quirked in a small smile. “I hardly think it proper for your butler to share your bed, my lord.”
“You wouldn't be sharing my bed as my butler, you would be sharing my bed as my lover.”
At the word lover Sebastian grinned.
“Yes, my love.”
