Summary
“Permission to speak, my lord.”
Ciel looked down, drinking in the sight of his butler kneeling under the desk, a red collar tightly clasped around his neck which was connected to a leash. Sebastian’s shirt and jacket had been discarded in the bedroom well before they arrived at the office.
“You may,” Ciel said lazily as he hoisted a foot onto Sebastian’s shoulder, digging his heel downward.

Summary
“Sir, this cabin is so cold,” he whined pitifully. “Won't you come warm me up?”
Sebastian peered disdainfully at such a sinful display, letting his own demeanour drop from warm to frigid.
“So you could stab me clean through? I don't think so.”
Ciel’s invitingly large pupils shrunk into sharp slits, his head tilting imperceptibly as it let out a curious, “Oh?”

Summary
Now that Gabriel remembers Sebastian he wants to love him properly and that starts with making love to him in the gentlest way possible and getting off to his tears.
#1 Kinktober but we start it with soft tender sex and dacryphilia because this is the kinkiest shit if we are being honest
Or
Sebastian’s weak arms reached down to grip his own thighs against his chest but he whimpered, as the medicines softened his muscles. His eyes watering.
“I–I can’t~”
Gabriel smiled and softly replaced Sebastian’s hands with one of his, using the other to prompt a pillow under his small hips, before he inched closer and started pushing inside Sebastian.
Sebastian tensed and stilled, clenching. Gabriel groaned and captured his lips in an open mouth kiss.
“Open up for me hubby. Come on, it's me, Sebby.”

Entry for CielSebaWeek2025 Day Three (3rd Sept): Power Imbalance/Powerplay, Orgasm Denial, or BDSM.
-
Ciel slammed a desk drawer, glaring down at his paperwork. “What do you want?” snapped Ciel. “Spit it out or leave me alone.”
Sebastian bowed slightly. “If you desire any assistance with relieving your stress, I shall wait in your room, my lord.”
Ciel paused what he was doing, clearly reading the suggestion hiding under the polite tone. It wasn’t enough to get him to calm down, which secretly pleased Sebastian. “Can you think of nothing but your beastly desires?”
“Yes: your desires.”
“My passionate feelings are not of the loving kind at the moment, Sebastian.”
Sebastian smiled. “I know. Shall I wait for you to join me?”
Ciel stared at him. “You’re in the mood for that? At the drop of a hat?”
“I’m a creature of truly reprehensible impulses at heart, young master.”

Summary
Now, Ciel didn’t wish to do any permanent damage to his butler—that would be counterintuitive, of course. He needed Sebastian fit for service tomorrow. But he wanted to watch him bleed. Groan in pain, shake with adrenaline, or whatever it was that ran through the disconnected veins of an artificial human body.
Or - Ciel finds a dangerous new toy to play with.

Summary
A caress so soft on his face, a cake so sweet in his mouth, and yet all those actions were so bitter and sour, leaving a strange aftertaste in his mouth. It was difficult to munch all that cake, to swallow it down without choking, having such a tight collar around his bulging throat.
He held his own knees, the only support he had, trying to embrace both the shame and the piece of cake that was slowly sliding down to his stomach. The worst part wasn't even that he could barely breathe, he felt his neck tied up and his head leaving his body: it was the fact that, despite all of the pain given by that stupid collar, he couldn't hate it.

Improper Use of a Contract Seal by peanutbutterjellyfish

Summary
Any manner of wickedness was a fitting look upon his master, and jealousy was no exception. Sebastian obediently followed Ciel through the hotel lobby and into the elevator, sensing that his lord’s initial amusement at seeing Sebastian flounder in Modri’s presence was evaporating and coming back down as something else.
“If you’re going to be angry at me,” began Sebastian. “I do wish it was over something I remembered.”
“That can be arranged.” Ciel’s cold tone could have sent grown men running, but Sebastian’s interest was piqued.
OR:
Ciel tests just how effective his commands are on Sebastian's body in bed. Sebastian admires his master's deviousness.

Summary
During a particularly demanding project for a client, you help Sebastian de-stress the only way you know how.
—
Sebastian's sure he’s in over his head. He figures he has been since you'd first stepped foot in Stardew, clad in loose-fitting overalls and an unwavering confidence to match. He was in over his head when he’d taken you out on his bike, and when he stood before you clutching a pathetic bouquet that he had practically crushed in his clammy hands, but he thinks being here now with you beneath his desk, hand working him in slow and almost lazy strokes as you gag around his cock, surely takes the cake for times he's found himself in a compromising, though not unenjoyable, position with you.
