Summary
When Ciel Phantomhive presented as an Omega, a dark creature rose from the depth of hell.
Of course the young boy didn't know about it, he didn't know anything of what his future had in store for him.
His servants brought him far, far away from his home since as an Omega, it was too dangerous for him to stay there. He shouldn't have presented as an Omega. The entirety of the Aristocracy was already making plans about how to destroy the Phatomhive family, now that a "weak, useless" Omega was at their top. A shame. Embarrassing. Humiliating for the whole Aristocracy.
Ciel had to leave as fast as possible right after his first heat, his loyal servants bringing him to a boarding school where he would be safe for the time being.
An Alpha with pitch black hair greeted him right at the front gates, wearing a dark cloak, a perfectly fitting suit and a neat tie.
Who would have thought that Ciel was greeted by the devil in disguise ?
His fated mate.
Sebastian Michaelis.-

Summary
Same as always, you opened your eyes and you were in the familiar dark room with Sebastian.
You had died.
Again.
It was routine at this point, something would go wrong, there would be a moment of overwhelming fear, an instant of unbearable pain, and then you were here. And it was fine. No injuries. No scars. No reason to be upset. It was fine.
This time it wasn’t.
In short, you cry in front of Sebastian and he comforts you.

i thought that you were so beautiful (it was love, i guess) by ghostlypink for yildiz

Summary
“Which one is he?”
“The one behind the counter.”
The demon looks.
There, across the street, is a small establishment with a glass storefront, decorated simply in warm hues of brown. The space inside looks cramped, especially with the amount of people hanging about, young men of various fashion tastes crowded together and—
(No. No…)
The demon stares.
Ciel Phantomhive looks the same as the day the demon saw him last, warm and soft and beautiful even as the light gradually faded from his mismatched eyes.

Summary
Sebastian’s lips flick up into a grin. “Shall we?”
Scowling, the earl hisses, “You want me to practice with you?”
“Of course, my lord. Who else is there for you to practice on?”
“Lau, or… Ran-Mao,” The boy offers helplessly, though even as he says it, his face sours.
“Do you prefer their company over mine, my lord? You wound me.” It comes out far more bitter than intended, acrid on his tongue.

Summary
“My lord,” Sebastian says at his elbow, “May I ask-”
“You may not,” Ciel interrupts, not looking at him. He focuses on the table in front of him, laden with food. He’s been picking at his plate for an hour, watching, stewing.
“There’s nothing to be jealous about,” Sebastian tries. “I would never-”
“Jealous?!” Ciel asks, whirling on the butler. “I am nothing of the sort.”

Summary
“Bend over,” he instructed.
She obeyed. In a flash, her petite frame arched over his desk. He struggled to tear his eyes away from the curve of the small derrière as he stepped closer, leaning in to whisper in her ear.
“You will count,” he murmured. “In Latin. You’re a clever thing, Phantomhive, so I’m sure it won’t be a problem, will it?”
She was silent, save for the ragged rise and fall of her chest against the polished wood.
He removed his gloves and stood at a slight diagonal, positioning one foot slightly ahead for balance.
Shifting his weight forward, Professor Michaelis raised his dominant arm and delivered the first strike across the Phantomhive girl’s bare bottom.
(Summoned to Housemaster Michaelis’ office, Cielle Phantomhive faces questioning over a scandal that’s shaken the academy. But as the exchange escalates, it becomes clear that neither teacher nor student is quite what they seem.)

That Butler, Hosting by Cr4shjay

Summary
After the Queen reports a series of disappearances linked to a private academy called "Ouran Academy", Ciel Phantomhive is sent to investigate. Unfortunately, it's very difficult to get any investigating done when some of the more influential people at the school are insane.
(Same setup as the Weston Public School arc, but this time I sent Ciel and Sebastian to Ouran because it's funny when they suffer)
(I shoved Ouran back into the 19th century)-

Summary
Ciel’s mind raced to make sense of what Sebastian was implying. “You intend to keep everything on? In bed with me?”
“With the exception of the gloves, yes. Should I need to, the front of these slacks unfasten, so there’s little point in me disrobing with you.”
Ciel stared.
“What’s wrong with you?”
Sebastian stared right back. “As I said, it’s a preference. Demons don’t like to be vulnerable, you know.”
“So that’s what this is to you.” Of course it was about power. Ciel’s eyes swept up Sebastian’s well-dressed form. He could admire how sharp and elegant a figure Sebastian cut under him, but Ciel had no interest in passively letting Sebastian do as he pleased with him. If Sebastian’s precious aesthetics were so important to him that he expected to bed Ciel like any mark he’d had in his life, aloof and controlling while his prey fell apart under his touch, he was mistaken.
Ciel folded his arms. “Fine. If you’re going to be like that, I forbid you from taking any of my clothes off either.”
It was Sebastian’s turn to gawk. "Pardon?"

Bookmark Notes:
That's exactly the vibe I wanted to hit on, them having this dynamic but having room for fun/laughing at themselves. Book of Murder is probably my most direct canon inspiration for their tone here where there's a lot of wanting to get back at the other but a sense of playfulness underneath them messing with each other. Thank you so much for commenting!
