Notes
     Sebaciel Trick or Treat Halloween Event hosted by QWC, Prompt given:
     Creep_by_Radiohead
          A few TWs I’d like to mention before you read: Self-injury,
          depression, bullying, blood. Although I have cut a lot of
          sinister out of this, it is still a bit dark to reflect the
          wonderful air this time of year brings. Not your usual soft
          and sweet drabble but a gradual build with a delicious
          treat. A modern AU one-shot with a wicked twist, please
          enjoy.

No matter where his parents moved him, Ciel always put his bed against a
window. That way, whenever it rained at 3am, he could sit up and and listen to
the drops splatter against the pane.
He placed his palm on the glass, the cold relieving the hot sensation that
overtook his skin. He watched as a white cloud of condensation spread around
his fingers. His bright azure eyes reflected back at him, shimmering with his
own precious raindrops that graced his soft cheeks. A candle was lit, bright
and red, next to him on the sill. The flame licked back and forth in the air,
drops of wax sliding down the stem to pool at the base. Just as the crimson
drops had fallen off of the thirteen-year-old’s fingertips a few minutes prior.
The porcelain skin of his wrists puffed magically, colored wicked with beauty
and tragedy as a blade had strewn through them as easily as silk and butter. He
glanced at his limbs now swaddled in gauze, swallowing as he reveled in the
calm of the rain and the candle. He was bewildered by the beauty of two
opposites existing at the same time.
Ciel often thought of something beautiful appearing on the other side of the
glass, something enchanting. Something like an angel. Yes, an angel that could
sweep him up and out of his misery, that could show him light, show him calming
clarity and release him from this Hell that tore him apart every single day.
The wax had cooled into a puddle of red around the candle when he blew it out
and decided to sleep. The smell of the rising smoke always calmed his nerves,
but not this evening. Not after glancing out in the rain and seeing some sort
of dark silhouette. Some sort of flash, some sort of figure.
He buried himself under his blankets, knees to his chest as gripped the cover
tighter around him. The scent of the burning wick was still in the air and he
smiled to himself as his pleasant thoughts finally had him drifting off into a
calming sleep.
Perhaps it washim.
Perhaps it was his angel.
===============================================================================
Sitting in class had been no different than swallowing broken glass to Ciel. He
had heard it all before. Heard the kids’ laughter, heard the teachers’
sympathy, heard the nurse’s prodding on the bandages on his wrists.
Ciel always chose the desk next to the window. That way, when everyone
questioned his dark attire, the shadows around his eyes from lack of sleep and
coal-black liner, the haunted aura he gave off, he could glance outside and
escape. He expected this sort of energetic chatter on this day. Halloween had
arrived. Halloween was alive and kicking and the scent of cheap candy, slutty
costumes and wannabe goths was in the air. He sighed, counting the beautiful
raindrops that slid down the glass, when there…
There it was again.
His chair screeched against the floor as he his lifted his hand tipped with
black nails into the air, “May I be excused?”
The instructor had every right to give him a crooked look. Ciel never spoke up.
He never asked to leave. The room erupted with soft chants, his ears picking
out the words ‘creep’ and ‘weirdo.’ He smirked. It was as if they were tattooed
across his forehead, burned into his porcelain skin, dripping with blood.
Yeah. That’s what he was, he remembered. He remembered every fucking night that
he didn’t belong here. Not with any of them. The overly charming grin that
suddenly cut across his face had the instructor catching his breath, “Well? May
I?”
“Y..Yes, Phantomhive. See to it that you return immediately.”
It wasn’t a minute later that Ciel was dashing out of the school. The rain had
stopped but the misty air had him squinting as he ran straight for the sports
shed. He flipped the light switch on, shutting the door behind him, “Where are
you!?”
Silence filled the small space.
“Why are you following me? Can’t you show yourself?”
Silence again.
Ciel leaned up against the door, covering his face with his hands as he began
to catch his breath. He had forgotten all about his asthma, not as if he cared.
He tightened his hands into fists as he whispered into them, “I just.. want my
angel.”
The light flickered and shut off, darkness overtaking the shed and the small
boy. He opened his mouth to yell when the air became so thick, he could choke
on it. He dropped to his knees, clutching his chest when a soft noise had him
looking up. There, before him, was a face, mere inches from his. Darkness
masked the upper half but he could see the soft skin that graced a handsome
jawline, the dark strands of hair that fell to tickle it there, and the soft
set of lips that parted to make a show of razor sharp teeth. A hot tongue came
out of the mouth, slowly and ever so gently brushing the set of quivering lips
before it. Tears escaped Ciel’s eyes, the terror causing him to be shocked in
place. He was sure the tongue was now prodding his lips apart, licking small
circles on his teeth and gums, so why.. Why could he hear a voice?
The light suddenly came back on. Ciel collapsed onto his front, shaking and
gasping for air as tears continued to escape his eyes. He looked up. He was
alone.
He stood and wiped his tears. Of course he was alone. He was always alone. He
licked his lips, the delicious flavor left there making his knees buckle. He
remembered the words he heard, loud and clear.
‘There are no angels in Hell.’
He clutched his pants, the excitement still coursing through his veins. Ciel
Phantomhive was always alone. His thoughts reflected in his smirk. ’Always… but
not for long.’
===============================================================================
It was as if he lost all of the facade he had worn throughout his long and
endless days of torture. Later that evening, he ripped through his house,
calling for him. Calling for the sweet creature to return.
Hours passed, the sun left the sky, his patience had evaporated.
Ciel’s parents found him in the basement, surrounded by candles, soot drawn on
the ground, ancient books open. When his mother reached out to touch him, he
screamed. The dark liner ran down his cheeks as he yelled through clenched
teeth.
“I need him! I NEED HIM! LET GO OF ME, GET OFF!”
His father grabbed him as his mother blew out the candles. When the sight of
blood illuminated what looked to be a poorly drawn pentagram on the stone
floor, she broke out into sobs.
Ciel continued to howl as he was wrenched up the stairs, “NO! WHERE ARE YOU!?
L-LET ME GO! AARGH!!”
Ciel’s blood stained his father’s shirt as he was torn from what he thought to
be his only salvation. He just wanted it one more time. To hear that sweet,
sweet voice. To know what else it could say. Oh to know!
It was going to be a long night in the Phantomhive house. Ciel was locked in
his bedroom, nowhere to go. He watched the rain fall, watched the trick-or-
treaters walk along, watched his sensibility leave him. This time, he did not
light his candle. He swallowed. Tonight would be different.
Something would change.
===============================================================================
He knew he shouldn’t be here. Of course he did. A graveyard on Halloween night
was no place for a child. Yet here he was, soaked from the rain, breaking his
parents’ rules. He shivered as he looked at the gates leading inside of the
graveyard. The rings around his eyes were all natural, a dose of hourly
screaming, blood loss and barely eating was to blame. He clutched his drenched
jacket closer to him, huffing when he placed a hand on the cold, rusted steel.
His voice came out in warm, white clouds.
“I know..you’re here.”
The air seemed to bend, a dark mist erupting from behind a far tree, curling
around a tall figure’s feet. Ciel’s eyes widened in shock, a small gasp
escaping him as he pushed the heavy gate open when the figure suddenly turned
to walk away.
“N-no!”
Without a second thought, Ciel picked up into a run. The outer grounds of the
graveyard were littered with thick trees that had his mind spinning as they
blurred by him in the dark of the night.
“Come back!”
His lungs burned, his legs trembled, his heart threatened to give out but, oh,
he was not slowing down.
“Stop!”
He pushed even harder, running, running, faster and faster until he finally
broke out into the middle of a set of grave stones. The wet grass had a foot
suddenly giving out, Ciel falling on his face, crying out as the ground dug
into his wounds. He slowly rose, clenching his jaw as he cursed out from the
blood that came from the side of his lip before a single finger suddenly lifted
his chin.
Ciel trailed his gaze up very slowly, bright blue eyes meeting a set of red
that seemed to pierce him to his very core. He could do nothing but gawk, jaw
slack, at the beautiful creature before him.
It was him.
The man towered over him, black hair falling down to cup his chin, features so
wretchedly gorgeous, men and women would fall to their deaths for such a being.
And they have. Ciel was sure of it as he swallowed, tears pricking the corners
of his eyes from how painfully perfect he was.
Dressed in a long black robe, the mysterious creature leaned down to level his
face with the child’s, “You call for me.”
Ciel was trembling and he was sure the man before him could tell. He attempted
to steady his breaths before finally whispering out a response.
“Y..yes.”
“And why is that?”
“I..”
“Wish to be saved?”
“Yes..”
“I am no savior.”
“B..but,” pain twisted Ciel’s features as he felt his dream, his only salvation
slipping away from him, “m-my angel-”
“I am no angel, child.”
The mist in the graveyard suddenly darkened to a pitch black color, ruby tinted
eyes shining bright as they reflected on Ciel’s face, “I am a demon.”
Ciel’s eyes widened when a flashback from his efforts in his basement a few
hours prior flashed through his mind. He released out a shallow breath. A
demon.
He had guessed right.
The creature smiled when Ciel jumped from a soft thumb pressing against his
lips. What was a demon like him doing playing with a child like this? Such
beauty in a small human being, such pain, such light… and such potential for
darkness.
“Let me into your deepest pits, Ciel Phantomhive. I want to taste you from the
inside out, bind you with my wretched coils and savor your every pleasure on
the tip of my tongue. Give me a name and I shall be yours.”
Ciel opened his lips beneath the thumb, his voice catching in his throat before
he shut his mouth. The demon stared at him for what seemed like an eternity
before those blue eyes shut, Ciel’s head dropping in defeat. The warm hand fell
in return, “Well then…”
Upon feeling the cold absence where the dark creature had touched him, Ciel
jerked his face back up with a gasp. He was gone.
And Ciel Phantomhive was alone.
“N..n-no..,” Ciel dropped to his knees, beating the soggy grass beneath his
fists in spite of his regretful hesitation, “don’t leave me!” His breath
quickened, his heart raced, his sight faltered as he screamed at the ground in
the empty graveyard, “I don’t want to be alone! I.. I don’t belong here!” A
million thoughts ran through his mind, the cold of the night biting his frail
lungs as he struggled to get a grasp on his thoughts, “Please! Come back! I’ll
name you! I want you! And.. I’ll call you.. I’ll call you…
SEBASTIAN!”
Without a moment’s hesitation, Ciel was suddenly flipped onto his back, head
falling into the sloshy lawn. His skin was ice cold, his body overworked and
weak, his eyes wet and red… but nothing made him feel more at ease than the
crimson gaze of the man pinning him down.
“Say it again.”
“I said.. I said I’ll call you-!”
A hand marked with an intricately webbed design covered the boy’s mouth as the
demon leaned in an inch before his face, “Slower…”
Ciel took a deep breath through his nose, the hand sliding down to cup his chin
instead when he raised his voice barely above a whisper, tainting his mouth
with the name, dripping it slowly and delicately off of his tongue as it
caressed the demon’s ears,“…S e b a s t i a n.”
Ciel gasped when his jaw was wrenched open, hot lips suddenly parting his own
with a feverish kiss. He wriggled, lifting both hands nervously before they
were pinned above his head. He moaned into the mouth working his own when he
felt the warmth of the strong grips soothe the wounds of his wrists. His jaw
slackened, his breath quickened, his tongue tasted and oh, how sweet this was.
Sebastian trailed his hands down the slender body, caressing every curve as
they went before tugging at a waistband. Ciel broke the kiss, throwing his head
back when a hand slipped beneath his pants to tease the growing need between
his legs. Sebastian continued to tug the soaked garments off with one hand as
his other gently rubbed back and forth over the virgin boy’s erection. Ciel
squeezed his eyes shut, moaning out onto the lips that gently whispered onto
his, “Whatever makes you happy..” one more tug and the slender legs were free,
another gasp escaping Ciel as he was so carefully teased and tortured,
“Whatever you want… I will give it to you.”
Sebastian gripped onto the svelte legs, parting them as he watched his new
master writhe beneath him,“I am going to possess you now.”
Ciel tossed his head from side to side, rising his hips into the air as he
begged for more, more friction, more lust, more of him.Although he was
practically nude, he felt so incredibly warm, even hot. The darkness that
surrounded him hugged his body, caressed his young skin and doused him in a
cloud of pure pleasure.
Sebastian’s impatience had him stuffing three fingers deep into the boy until a
howl so delicious escaped the body and had him shaking beneath his grip. “I
cannot save you from Hell,” he twisted his fingers before retracting them
completely, “but I can make it your playground. So now,” he gripped onto the
supple thighs, leaning forward to release himself and press the tip of his
length against Ciel’s entrance, “scream for me”
Upon feeling Sebastian’s cock enter him, Ciel did just that. He arched his back
high off the ground, releasing a gurgled cry when Sebastian leaned down,
scooping him up into his lap. He pressed his mouth on those pretty lips to
swallow every cry that came from his new and very young master.
Ciel shivered, but oh, how good it felt. To be accepted, to be wanted, to be
had, to be… consumed. He wrapped his legs tight around the demon, strong arms
caressing the entirety of his small frame as Sebastian thrust hard and deep
into him.
The virgin boy was perfection, sliding on and off his cock as if he were made
for the demon, sucking him in harder and harder, further and further. Sebastian
growled, biting down on Ciel’s neck and breaking delicate skin. He lapped at
the delicious, crimson treat, trailing kisses up and back down to his
collarbone, biting more, sucking more, claiming Ciel as he pushed further into
the soft, tight treasure of a boy he had found.
“Ahh~! Mm..more~”
Sebastian wrenched Ciel off of his lap, flipping him over to have his plump
bottom high in the air. He buried a hand into the dusty locks of his new
charge, wrapping his other around Ciel’s cock before re-entering the small
cavern.
Ciel clawed at the grass, releasing lascivious moans with every slam, every
smack he heard from Sebastian’s cock pumping in and out of him, hard and
steady, causing him to salivate. His hair was pulled, his own dripping erection
was being stroked and his insides were on fire. He pushed off of the drenched
lawn, more onto his demon, grinding him harder into that spot that made him
quake. It felt so good, nothing had ever felt so good, and he couldn’t get
enough.
“G..god!”
Sebastian grabbed Ciel’s hips, flipping him over on his back while remaining
connected. He seized the boy’s ankles before leaning in and pushing them up
before whispering onto gasping lips, “There is no god here.”
Sebastian held the slender legs high in the air as he sunk further into Ciel,
sliding his cock as deep as it could go, relentlessly claiming him from the
inside out.
“Ciel Phantomhive,” Ciel shuddered at the sound of his name, moaning out an
‘mmm’ in response, “you are mine now.”
Sebastian gripped harder onto the thin ankles, spreading them further apart as
he leaned down to stuff his tongue into the noisy little mouth. Ciel lifted his
hips up as best as he could to meet every thrust, licking and sucking on
Sebastian’s tongue as he found himself in his own personal Hell.
And he loved it.
Sebastian nibbled on Ciel’s lips, “That’s it,” he slammed into Ciel, taunting
the darkness out of him, pushing the sweet child further and further to the
edge, “what a good boy,” deeper and deeper, harder and faster, making a
complete mess as he plunged into the small body, “do you like me deep inside of
you, Ciel?”
The child moaned, licking the lips above his as he desperately lifted his head
to get more of a taste.
“Do you like how I fill you? Does this feel good, little one?”
Ciel writhed beneath Sebastian, small cock dripping onto his stomach as his
demon continued the ruthless torture on his prostate. Sebastian hummed in
satisfaction at the mess of a boy beneath him, “Say it. Say what it is that you
want and I will give it to you,” he licked the little tongue searching for his,
“There is only one thing you will ever desire from now on. You are on the edge
of desperation and there is only one thing that will ever give you pleasure
from here on out. Tell me what it is, little one,” Sebastian bit down on Ciel’s
tongue, sliding out to slam back into him, “Say it-”
“Se- ngh! Sebastian!!”
“Mmm, good boy,” and with that, the demon’s eyes brightened like glowing embers
as he buried himself in the boy, claws sinking into the velvety skin of Ciel’s
ankles as he released hot, sticky lust within the tight and oh-so-succulent
little child. Ciel cried out, choking on moans as he spent, hard and messily,
body pulsing and hot as he writhed in euphoric pleasure.
Sebastian released the boy’s limbs, lapping at the drops of blood on his onyx
tipped nails before releasing a chuckle filled with ringing sensuality and
satisfaction. 
What a splendid little treat he had found.
Small hands jet out to immediately grasp onto Sebastian, the demon scooping up
Ciel as they continued to grip onto him desperately as if he would disappear
any moment. Quivering lips parted to let out a soft whisper, “Sebastian…,” the
demon leaning down to kiss a sweat slicked forehead as he listened to his first
command, “don’t ever.. leave me.”
Sebastian smirked, glancing around at the gravestones that represented how
fickle humankind could really be, how ironic it was to have a boy of flesh and
bone asking someone immortal to not leave him. He held soft cheeks in his
hands, planting a sweet kiss upon the most delectable thing he had ever come to
know.
“Yes, my lord.”
===============================================================================
No matter where his parents moved him, Ciel always put his bed against a
window. That way, whenever it rained at 3am, he could sit up and and listen to
the drops splatter against the pane.
He often thought of something beautiful appearing on the other side of the
glass, something enchanting. Something like an angel. Yes, an angel that could
sweep him up and out of his misery, that could show him light, show him calming
clarity and release him from this Hell that tore him apart every single day.
Little did he know it was Hell that would bore his savior. It was Hell that
would save him. 
It was Hell that brought him the Devil’s angel.
The shimmer of an intricate web in his eye that now connected him to his saving
grace reflected in the window. The glass mirrored the demon on his bed, buried
deep between his legs as Ciel thrust his hips up, throwing his head back in
pure pleasure.
The hot tongue that wrapped around Ciel so deliciously had him groaning out in
pure ecstasy, tugging on long hair, clawing velvety skin, grinding deeper and
deeper into the hot, black abyss as he chanted his favorite prayer,
“Se..Sebastian, ah! Feels..so good, m-more, ngh! Sebastian!~”
A candle was lit, bright and red, next to him on the sill.
Ciel writhed in the dark pool of pleasure, tears staining his cheeks as the
feeling of being so overwhelmingly accepted and safe, so full, so wanted and
completely consumed had him wondering what could have possibly awoken such
burning and aching passion within his blood.
Still enraptured in a lustful grasp, he let out a breathy chuckle at his
resolve.
Perhaps it was him.
Perhaps.. It was his demon.
A gasp, and growl, and the candle’s flame fluttered out.
