Summary
At eighteen, still unavenged, Ciel continues to serve as the Queen’s Watchdog, with Sebastian remaining as his loyal butler. But now that he’s older, their relationship begins to change. It’s hard to stay distant when the darkness surrounding his butler becomes increasingly alluring.
The story will be written in arcs, like in the manga. Here are some of the ideas:
ARC 1 – ENDLESS DREAM: After getting injured on a mission, Ciel wakes up in a world where his parents are still alive. Were those years with Sebastian nothing but a dream?
ARC 2 – HUNGER: On Elizabeth's birthday, Ciel must propose to Elizabeth while investigating a series of crimes of passion—crimes that even Sebastian seems to be affected by.

Summary
> Brat <3 sent an image
Sebastian immediately opened the notification, his attention shifted entirely away from the presentation. His mouth nearly fell out of his jaw as he laid his eyes on the photo.
It was a front facing shot of Ciel kneeling on the bed in the tightest black latex he had ever seen. He was wearing a crop top that stretched across his chest in a way that left absolutely nothing to the imagination, stopping just under his sternum and leaving ample room to show off his waist. Below the shirt were low cropped shorts which cut across his hip bones, stopping about halfway down his thighs.

Summary
London, drenched in endless rain.
On a routine carriage ride home, the Phantomhive household crosses paths with a mysterious young woman—Riku—whose chance misstep leaves her injured and stranded before the Queen’s Guard Dog himself.Bound by courtesy (and Sebastian’s stubborn sense of “hospitality”), the woman is brought to Phantomhive Manor… but peace is short-lived. Within its walls echo laughter, chaos, and a butler whose every smile hides something far darker than mere servitude.
As Sebastian tends to her wound with unnerving grace, Riku can’t shake the feeling that his eyes see far more than they should…
And in that quiet, where rain meets silence, the fates of human and demon intertwine for the first time.“Welcome to Phantomhive Manor, Miss Riku… I do hope you find your stay pleasant.”

Summary
Ciel could count on one hand how many times he’d seen Sebastian in his true form. It was the sort of memory that became less and less focused the more he tried to concentrate on it. During waking hours, Ciel couldn’t quite picture it in full, his mind rejecting the very idea.
But in dreams, he could recall it all too well.
The demon was disgusting, a mass of shadowy limbs and odd angles, cool to the touch. Always shifting, hard to get a good grasp on aside from its enormity, its all-encompassing darkness. And it was chock-full of eyes, following Ciel’s every movement.

Summary
His sweet angel. The older one was strong and brave, always confident in everything he did. He would grow up to be fine and well-adjusted. Vincent never worried about him.
The little one, though. He was a daddy’s boy, delicate and afraid and in need of guidance. And so sweet, trusting his daddy unequivocally. He would start to grow up soon, would start to pull away from Vincent, but he wanted to prolong the inevitable. He’d like to keep the boy just like this forever.
“Give Papa a kiss,” Vincent says, squeezing the boy’s thigh. It’s soft and giving under his touch.

Summary
'And why put so much effort? People like my father, the nobles, are condescending peoples. They would look down on you anyways.'
Scoffing I said, ''Noveau riche' is what they call people like me'. But Ciel grew quieter. Shoulders slouching posture slacking. Leaning closer a hesitant demand, a whisper left her lips,
'Would you paint me again?'

Summary
‘“Desperate, are we?” the demon murmured, the tip still engulfed in his lips.
“Aungh~!”
The young master whined breathily. He attempted to shove Sebastian’s head down further, as inconsiderate as ever, but the force was hardly enough to make him budge. The butler acquiesced nonetheless.”A short little one-sitting blowjob fic

The line between servant and predator blurs, as a twelve-year-old boy and his demon butler struggle to survive each other, and London, long enough to finish their contract.
Sebastian: “Goodnight m—“
The boy mutters something under his breath. Instantly, Sebastian’s head snaps back towards the bed, past what any human neck could manage. The room freezes.
Sebastian: “Pardon?”
