"Inhale."
Indignation snubbed his pride. Ciel clenched teeth to hold in a complaint, then he drew in a breath that filled his lungs and expanded them.
"Good," Sebastian told him. "Now, let it out."
Ciel did. The air vaulted from his mouth, pursed lips, and he released it all. At the same moment, Sebastian gave a tug, and the corset wrapped around his middle cinched in tight. He made a pained noise, feeling it pressing him into a particular shape, and then he tossed back his head. Before him, the grand footboard of his bed was shaking as Ciel gripped it hard and used it to keep himself stead. The skirts he wore shivered around his legs, kissing him with silken brushes.
Quickly, Sebastian tied off the tight-laced corset and then stepped backward so he could examine his work. "Turn around, young master."
Ciel did, carefully, positioning himself so he was steady. His eyes, lashes fluttering, fixed on his intrepid butler.
"Mm." Sebastian curled a pleased hum around his tongue, then he smiled at Ciel with a warning glitter in his eyes.
"You find this acceptable?" Ciel asked him.
"It makes your body indistinguishable from that of a young lady of fine breeding." Sebastian's red eyes were full of amusement. That enjoyment grated on Ciel, but what was he going to say to dispel it? No. He knew Sebastian well enough by now to know that if he resisted the words, it only made the demon happier. "How do you feel in it?"
Ciel, instead of answering, walked to the floor-length mirror to examine himself. He was only in the undergarments. A cotton skirt with some satin lining, the corset, and the undergarment underneath. The corset itself was a delicate cream color with stitchings of dancing leaves all over it. He ran his hands along his waist, now tightened into a curve.
"How long will I wear this for?" he asked.
"The rest of the day. You can remove it at night, but come morning, it should be replaced." Sebastian tittered, and Ciel shot him an annoyed glare. "That is the way to maintain a shape, young master."
He needed to do that. At the end of the month, Ciel would attend a party, and if he were to be unclothed partially, they would need some assurance that his identity went undiscovered. Of course, there were risks, but this could potentially keep him safe. Ciel stayed watching himself. Behind him, Sebastian canted his head curiously to one side, allowing his dark hair to sweep his shoulder.
His voice was the model of concern; so sickly saccharine that it set Ciel's nerves alight. "Is something the matter, young master?"
"Hardly." Ciel turned sideways, then the other way, examining himself more closely. He was embarrassed to admit that he was growing to like this. The first time he had been forced to masquerade as a lady, he had taken it with shame, but… This was awakening something from a deceased cavity. "Prepare the rest of the dress, Sebastian. We will see if I can fool the servants."
"Yes, master," Sebastian said, grinning with wicked mirth.
For the day, Ciel wore a blue dress with a bow down the back, white trim, and a beautiful wig of flowing, black hair. They claimed that he was a young lady from France, traveling to meet with the Earl who was unfortunately doing his own traveling in the city. The servants might have suspected, but they all kept their theories in their own heads. It worked well; Ciel was pleased. Sebastian was more than pleased.
He remained there for the week, litling up his voice, talking quietly to the servants, being genteel, grateful, and unbothered by anything. He walked in the garden under a parasol; Sebastian's eyes seemed always on him. Ciel was not sure why.
He was waiting on a growth spurt which would render these charades impossible. He was waiting for deeper voice, facial hair, anything which made him more the masculine ideal that he should be. As the Earl of Phantomhive, should Ciel not be a prime example of manliness? Yet, he was able to live like a young lady with no one being the wiser. Each night, he watched himself in the mirror, practiced the way he carried his arms, the walk, how his heels needed to tap delicately instead of click in a domineering way.
During these sessions, Sebastian remained back by the wall, always watching with that half-smile that showed no teeth.
At the end of the week, he would go to London and try this ruse on others, ingratiate himself with the nobles there, and win himself an invitation to a party which hopefully held the key to unfurling more of the mystery surrounding the deaths of his parents. Ciel never forgot his goals. Never. He was always playing chess, even when dress-up was involved.
The night before, he stood before in the mirror in a dress of velvet red. The rose decoration on his chest was perfect, and the sleeves curled in satin twirls, exposing his delicate, pale shoulders. "Sebastian, undress me," he said boredly, after finishing his nightly practice ritual.
Immediately, his butler was at his back, beginning to part fabric and release Ciel from the dress. "My, my, young master. You are truly becoming the perfect young mistress."
Ciel gazed unflinchingly at him through the mirror. "Is that so?" he asked.
The smile on the demon's face was cat-like in its self-satisfaction. "Of course. Do you expect me to lie to you, young mistress?"
Ciel opened his mouth to respond, but a fuzz of interesting feeling zipped up his spine. Words were lost somewhere, and he fumbled for them, watching as fabric eased off his waist. Sebastian guided his legs to step free of the dress, leaving Ciel only in the corset, the tool skirt, satin-lined. Hands came to rest on his waist after Sebastian had put away the dress.
"Standing with your mouth open is hardly ladylike."
Without thinking, Ciel snapped his jaw shut hard enough to clack his teeth together. And he burned in shame for having responded that way to the taunt. He watched Sebastian in the mirror, watched the hands move around the middle of his waist. They squeezed him, enough for Sebastian's pointer fingers and thumbs to touch. He towered over Ceil, black-clad and handsome.
Wearing a smile that was devilish in its intentions, Sebastian said, "My… You seem perfect this way, young mistress. I cannot imagine returning you to your previous aesthetic."
"Why are you calling me that? We are in private," Ciel said, attempting to keep his voice measured.
Sebastian chuckled. "Are you claiming to not like the way I speak of you?" he asked him. "I think that's untrue, young mistress." He leaned in, and a flush brightened its way across Ciel's cheeks.
"Don't," Ciel whispered.
Sebastian's head cocked curiously.
Ciel swallowed. "Don't stop." He completed the thought and attempt not to feel shame as the demon smiled toothily at him.
"Yes, young mistress."
Ciel stared at Sebastian through the mirror, felt the breath on his ear as words whispered themselves to him. Feeling a strange stirring, in his gut, in between his legs. The arousal came very suddenly, or at least it felt like it had. And the way Sebastian curved his lips so evilly, Ciel realized that he knew it had happened.
He said, "My, my. I didn't expect that." Hands squeezed Ciel's waist. "I hardly had to do a thing at all…and already, you are excited."
Trying to keep his chin up was failing. Nothing about this resembled pride, but in the shame, Ciel found a strange pleasure. It worked through his body and between his legs. Even wanting to deny it, he knew he couldn't.
"Let us have a look."
Sebastian took a handful of skirt and began to fish it upward. The fabric bundled in his hand as he folded it down and slowly exposed the pale, thin legs beneath. The delicate socks were pulled up and held with garters above he knee, bows circling the top like floating wings. But Sebastian didn't stop there.
Quickly, Ciel looked away from himself.
"Why should the young mistress be shy?" Sebastian asked him. And finally, the air kissed at Ciel's upper thighs, and then… He felt the cool loss of fabric, but he refused to look at the mirror again and face himself and this bodily reaction. "Do you not enjoy it?"
Ciel hissed under his breath. "You are a wretched being."
"I am what you desire me to be," Sebastian reminded him.
It sent chills down Ciel's spine; he knew this to be true, without a doubt, and had no recourse to disagree. His body did not want him to. He could feel the heat pooled in him like a gathering of water straining in a flexible container. Like a stomach full to bursting, the appetite of the eyes too much for it withstand.
His lips danced over the words he needed. Ciel shut his eyes and inclined his head. At his back, Sebastian pressed closer. He pulled the skirts up higher and crooned.
"Touch me," Ciel finally spat out.
"Yes, young mistress."
If Ciel paid attention to the smugness, it may have ruined this for him. Perhaps, or perhaps not. It was difficult to imagine anything that would take away from the feeling of Sebastian's soft glove wrapping around his cock. He threw his head back; the strength of Sebastian's body supported him even when Ciel felt like his feet could not.
"I have you, young mistress."
Ciel made a soft panting noise as Sebastian stroked him. He flexed his toes against the carpet. "Do not condescend to me."
"I would never. That is an appalling thing to accuse me of." Sebastian wrung his cock, making Ciel groan in undignified noise. He looked into the mirror again, realized a string of milky pre-cum was dangling from the tip, and just as swiftly looked away.
Sebastian's curled lips brushed his ear. "It is easy to take you apart. Has the young mistress been desiring this for longer than I thought?"
Ciel wished to hide. He pressed a hand over his face. The growing heat in his gut made him nearly whine. Ciel managed to stop any such sounds from escaping.
"Is this not enough for you?" Sebastian asked. "Perhaps, the young mistress should request something new?"
"No." Ciel shook his head. "This is-"
"Is it?" Sebastian loosened his grasp. The cruelty of it sent a throb of need careening through his body. "Are you sure?"
Of course he wasn't sure. Ciel had to peer through his bangs which dangled before his eyes. He met Sebastian's eyes through the mirror, and he imagined violence for such a cruel trick. "I…"
"What? Do you wish for me to do more?"
Ciel bit inside his cheek. Sebastian teased his cock with barely-there touches. "Yes," he managed. "More."
"Is that how a young mistress asks for-"
"I demand more. I demand you give me the relief I need."
Sebastian allowed his mouth to curve in that slight, pleased smile. "Yes, my lady."
He piled the tool and silk into Ciel's hands, then turned him by the waist. Going where he was directed, Ciel found his back leaned against the footboard of the bed, and his eyes watched Sebastian's slow, sinking track to the floor. The butler went to his knees, sweeping back his hair.
"Allow me to pleasure you," he offered.
Ciel snapped, "Get on with it."
"It is my pleasure." Sebastian opened his mouth. Surprised, Ciel froze as his cock was taken in past Sebastian's lips. He moved himself down, heat sliding around the thin shaft, taking him all the way to the base in a single motion. It was swift; Ciel's knees knocked together. Strong hands kept him standing as Sebastian sucked on his cock.
Swirls of pleasure drove through Ciel's body, and his heart picked up into a gallop. He imagined the way a carriage would sputter at the edge of a road if the horses pulling it got spooked. Sebastian's mouth was a warm tunnel. Intensely tight. His tongue an ever-present spiral of intensity. There was no escape.
Ciel pressed himself into the warmth, holding his skirts, feeling Sebastian's hands cinching around his waist. It felt like he was being held, uplifted, over the carpet. Were his feet even on the ground?
No, he realized, seconds later. Ciel's back met the bed, and he watched his demon stalk over the footboard in order to join him. Breathless, Ciel meant to question Sebastian on what the hell he though he was doing, but the words never managed to trip past his gaping lips. Sebastian grabbed him around the waist again, then flipped him hard onto his front.
"Is it too much for your delicate constitution, my lady?" Sebastian's chuckle vibrated into Ciel's body as Sebastian laid over him. He grabbed the skirts and started hiking them up swiftly. "Would you like a gentler hand?"
Ciel groaned. "Don't you dare."
All his skirts were folded up to his back, exposing the creaminess of his thighs, the pert ass rising above. Sebastian was quick to grab, squeeze, rubbing the softness of his gloves along Ciel's skin. Ciel released a groan which only seemed to flatter the demon. "Do you not want to make your butler work for it?" he questioned, that aggravating faux-curiosity in his voice. "It seems you lose yourself so soon, my lady."
A pulse of warmth shot into Ciel's cock where it was trapped against the bedding. "Do not overestimate yourself," he sneered, grabbing handfuls of bedding.
A chuckle warmed the air. "Hardly. I know exactly what I am worth." He nipped lightly at Ciel's ear. Then, Sebastian went much lower. Ciel felt the heat in his cheeks, but he did not stop what was coming. Sebastian pried him apart, then pressed his tongue against his hole. The soft squirm of the muscle set all of Ciel's muscles loose. He felt like he had lost his structure. The form of his body fell apart at the seams.
Sebastian continued to lick.
"Nnhg! What are you- Why are you-" None of his words stopped it. That warm, wet muscle teased at Ciel's hole before plunging inside. Licking through him delicately, almost, desperately. Like he was seeking something. "Sebastian!"
His cry fell on deaf ears; the hungry demon continued to prod into his body. Hands pinched and massaged Ciel's ass during the assault. Whenever he moved, his hard, little cock rubbed against the bedding. Sparks like embers from a growing fire brightened behind his eyes. He threw back his head, feeling his spin curving, the corset still pressing him into the tender, delicate shape like a lady.
When Ciel thought he could take no more, Sebastian proved him wrong by pulling away. The clever demon sat up some, letting Ceil's cheeks close around his twitching, wet hole. "My, you seem to be in a state, young mistress." Ciel wished he could grab ahold of Sebastian and force him close again, but he could not move from his tense position. All his muscles had locked.
"Please," he whispered. "I need-"
"Oh!" Sebastian let out a delighted trill. "Is that begging I hear? When you could command me, instead you ask with polite grace. Your transformation into a young lady of noble birth seems to be completed."
Ciel's cheeks burned in shame. "You cannot leave me this way."
"I hardly would. To only do a job as important as this halfway, just what sort of butler would I be?"
If he retained more of his logical mind, Ciel would have rolled his eyes. But he felt weight pressing on him, the shuffle of fabric, then hard flesh pressing against his ass. He wanted to curse; the surprise flooded through him swiftly. Then, him knowing what was coming, Ciel inhaled sharply. One of Sebastian's hands settled in his hair and carefully took up the strands between his fingers.
"Sebastian…" Ciel managed, tipping up his head.
"There, there, young mistress. I will take very good care of you." His hand quickly grasped Ciel's hair tightly and yanked his head back. Ciel went, bared throat and collarbones, arching off the mattress. And Sebastian began sliding his thick cock into Ciel's hole. Jaw falling open, a harsh, punctured sound began to bleed out of Ciel's mouth.
Sebastian rolled his hips forward, inching more of himself into Ciel's tight body. "You're taking me so well, my lady. Perhaps you have desired this for some time. Have you thought of it before?"
Ciel gasped. "I-"
"Remember, it's not ladylike to lie. Tell me the truth. Have you thought of me ravishing you before?" Sebastian's voice held a twinkle of mirth.
After a few shallow breaths, Ciel said, "Yes. I have. I- Oh my-" Pleasure swarmed him and made him feel faint as Sebastian's cock carved into his body. There was a stretch that felt infinite, like it was taking every part of him over. His limbs had ceased to function, and all of his mind's thoughts were slowed to a crawl. His body could do nothing but feel as Sebastian eased into him slowly, slowly, slowly. Ciel's hole strained around his large cock, hugging it intimately. The entire shaft was soon enveloped by his flesh.
Being tied together like this almost brought a tear to Ciel's eye. But he maintained himself, only shivering mildly as he felt the heights of pleasure teasing along his skin. Sebastian pulled his hair more, then leaned in so his lips floated near to Ciel's ear.
"Does it feel nice?" His question was liquid and smooth, coursing over Ciel like spilled wine.
"Yes," he whispered. "Very…nice."
"How nice?" Sebastian prodded, barely moving. Even so, every slight shift felt momentous as his hole yawned wide to accommodate Sebastian's large member. "Be descriptive."
A flush worked over his face slowly, flowering out into bright splotches of color. Ciel could feel the heat in his face like a furnace, yet Sebastian's hand on his waist, even through the gloves, felt even hotter. "You're so big," Ciel gasped. "I can feel every inch of you. You haven't left any space inside me."
Sebastian chuckled. "Good."
A cry wrenched out of Ciel when Sebastian began to move. It was violent, sudden, the drag backward. All his body became stimulated, like lights in the distance, fire. Ciel felt the softness of a glove press over his mouth to contain his sounds. "Ah! A young lady does not shame herself with those kinds of noises. Let me assist in preserving your dignity." And he slammed inside again.
The force made Ciel go weak. His watery eyes blinked, mouth open, panting noises against Sebastian's glove. The demon butler did not stop there. He began to strike his cock deep inside Ciel's body over and over again, hammering away at him with intensity and focus. What could his body do but loosen, like stitchings undone, opening itself for that conquering thrust. Sebastian never seemed to lose his pace.
"There, there, young mistress," Sebastian whispered, as if he were attempting to settle a wild animal. "I have you. I will never let you go."
Ciel's heart thundered by even quicker, out-pacing his body and leaving him far, far behind.
Cock rubbing against the bedding, Ciel felt himself nearing climax. His mouth was behind Sebastian's glove, so he couldn't warn him or say anything about it. Instead, he could only rut himself forward with absolute insatiable desperation, and soon white warmth spilled between him and the sheets. He tightened around the battering ram of Sebastian's cock.
"Oh?" Sebastian chuckled. "So soon?"
He pulled himself free, leaving Ciel to gape and gasp. His mouth was freed from its imprisonment, and he sucked in harshly the air he'd been slowly denied. Trying to recover was not in his cards, though. Sebastian grabbed him, flipped him to his back, and threw him up against the bed's fluffed pillows.
Swanning closer, looking absolutely ravenous, Sebastian carefully used his finger to trace around the head of Ciel's cock. The sweet, tender, swollen member, now reddened and slick with its own seed. Some had spurted up onto the front of the corset, and Sebastian let his fingers brush the fabric and gather it up on their tips. "You truly are debauched, my lady. What would people say if they saw you in tatters for your butler?"
Catching his breath, Ciel said, "This is our clandestine tryst," he whispered. "I find it unsuitable for anyone else to find out about this."
Sebastian laughed. "Of course." Then, he licked Ciel's come off his fingers. "But we are certainly not done."
He grabbed Ciel's ankles and folded them up over the pillows, spreading him wide. Ciel quickly pressed his hands to Sebastian's chest, but instead of pushing, he arranged his fingers to hold tightly to his suit jacket. Ciel knew his hole was gaping, empty, still wet from Sebastian's slick spit. Wanting. Sebastian did not leave him empty long.
With a smooth thrust, he shoved back in, easily fitting himself into that cavern he'd carved open for himself. It was a beautiful stroke, quick and efficient, and he re-started his earlier pattern without a catch in breath. Ciel crowed, and this time, Sebastian let him sing his pleasure without attempting to stop him.
"My, my, young mistress. Look at how well your body takes me. I might even draw the conclusion that you were made for this."
Indignation had long died; all Ciel could feel in the moment was strokes of bliss. Sebastian aimed himself to find some magical place within Ciel that turned all his thoughts into vapor. Everything evaporated slowly as he clutched his demon butler tighter, keened out his name, and stared upward into those scarlet eyes. His cock was already stiffening again in preparation.
The entire time, Sebastian smiled without teeth. His calm stretched above Ciel like the view of a field of wheat, long-since turned golden in the sun. He was a dangerous beauty. There were many ways to fall for a man like Sebastian, yet he was no man at all. He was a beast from the deepest pits of hell, here to serve only Ciel.
And in that moment, Ciel was so grateful. No one else could have ever given him this.
The second orgasm fell into him like weight; his body rigid, streaks of white thrown across his corset. And Sebastian shoved in and began milking ropes of his own white seed into Ciel's body. The demon was holding his ankles so tight they felt bruised, but of course, he would never. And So Ciel fell back, into the pillows, into the clouds, panting as he enjoyed the sensation of his body filling with Sebastian's seed.
When Sebastian began to shift out, some unmeasured stretch of time later, Ciel gripped his loosening hands tight again. "Wait," he commanded.
Sebastian leveled him with a look, inclining his questioning gaze to one side. "What is it? What is your instruction?"
Ciel blinked his eyes up at Sebastian, wondering if he enjoyed the claiming mark emblazoned into Ciel's right eye. "Stay inside me for a little longer."
With a chuckle, Sebastian nodded his head, acquiescent to the demand. He spoke once more before allowing Ciel to drift and feel, thinking of nothing but his stuffed body and the demon's seed hot inside him: "Yes, my lord."
