I am dying to read Prepositions 😭 some Sebaciel headcanons please please please PLEASE

I’m suffering from Prep withdrawals this weekend, too *cries* so have some zesty-lemon Sebaciel Prep headcanons! Some will make it into the fic. Some won’t, but they’re all floating around in my head...

~ Ciel, as a perfect product of Victorian repression, is almost as aroused by the sight of a bare neck or elbow as he is by genitalia. 

~ Sebastian spends most of his time in an uneasy state of semi-arousal in much the same way as he’s perpetually hungry. But he’s designed for irregular meals, and for extended mating that has little to do with reproduction. He has no scruples about seducing anyone and considers himself Quite Good At Sex, but his own pleasure is much more complex. It takes him a long time to come. And he usually doesn’t bother to try, not with mortals.

~ Ciel doesn’t like looking at himself naked in the mirror. Whereas Sebastian has trouble looking away again.

~ Sebastian is an exceptionally attentive lover. His knowledge of anatomy is breathtaking. His timing is almost perfect. Because if the creature he’s fucking fails to finish in anything less than a whimpering heap, he takes it as a personal affront and will begin the whole thing again. Do not attack his ego. 

~ Ciel is a horny lil baby. But if he had the option to simply be cuddled, he would almost always take it. He doesn’t have the option.

~ Sebastian really wasn’t happy about being stripped naked in the Phantomhive cellar when he was supposedly dead. Now, Sebastian’s shame level sits at about 1.5 %. This behaviour isn’t shame, it’s only ego. Again. Always. He simply believes himself so superior to mortals that he prefers to control when he undresses in front of them, in the same way a movie star would rather post nude selfies instead of having them leaked. He is the unbutton-but-stay-clothed-during-casual-sex type. (I suspect he finds his true form more lovely than this human one, too.) And if Ciel only realised this, he could use it as a weapon…

~ Ciel’s most sensitive spot is the bottom of his spine, right in the hollow of his tailbone. He doesn’t know it yet. But he will.

~Sebastian knows better than to let anyone know his most sensitive spot, duh. He occasionally implies it’s the frenulum of his cock. It’s not. (It’s the inside of his wrist.)

~ Being desirable is more important to Sebastian than being a top: a horny human is a vulnerable one. The demon is very, very versatile. But always dominant. One does not seduce Sebastian; one is merely permitted to believe so.

~ Ciel, on the other hand, would consider himself purely a top if he knew what the deuce that was. And he’s undoubtedly dominant too: his willpower is immense. His pride is worse. His demon is the only creature he will ever bottom for. Whether he submits is yet to be seen.

~ Ciel is intimidated by the size of his demon’s cock. He hints, one evening, that as an amorphous creature who is more than capable of adapting its form to the required needs, perhaps Sebastian might consider-- Sebastian pretends he has no idea what Ciel means. Ciel is too embarrassed to continue. Sebastian is most satisfied.

~ Sebastian talks during sex. Not just a few words: almost continuously. And Ciel, poor overwhelmed Ciel who hardly knows how to breathe and kiss at the same time, Ciel is both aroused and horrified. He’s flustered. He’s noisy himself, but hardly coherent, and often ends up murmuring shut up, shut up, shut up… Until the time Sebastian is hovering on the edge of his third orgasm, blank-eyed and fuck-drunk and almost silent, and Ciel is relieved. And frightened in another way completely...

47) "were you just masturbating?"

@akumahoshi-writes​ thank you for the request! (ao3 link)

Under The Table: 

“Were you just masturbating?” Sebastian asked far too casually, pouring the young Earl a fresh cup of hot tea. Ciel blushed so very red, all too aware of everything hidden beneath the large mahogany desk.

“How crass, I was doing no such thing” quickly regaining his composure the Earl forced a scowl, a facade of outrage. He would hide behind propriety and pride, deny and deny until even he believed he didn’t have a hand between his legs.

“Oh? Then why can I smell your arousal” the demon’s eyes gleamed, hellfire sparking mischievously in those feline depths.

Ciel tried to stop touching himself, slowed down so as to be unnoticeable, but the rhythmic stroking of his own hand was addictive. He was already so close, he could feel it, that pleasurable heat bubbling up inside him.

But the butler pushed into his personal space, pressing him against his overstuffed chair. Sebastian’s white gloved hand slipped down to grasp his own little hand wrapped around his prick, peeking out of his unbuttoned shorts. The demon squeezed, wringing a little sound from his soft peachy lips.

“I’ve caught you red handed” Sebastian smirked, and his little master hung his head, caught in a lie and reluctant to make eye contact. The butler’s thumb smeared those drops of precum gathering on the tip, the soft cotton of his butler’s gloves now stained with the Earl’s arousal.

“What a dirty little boy” the butler reprimanded, smirking lips contradicting his chastising words.

“Were you thinking about me?” Sebastian’s voice dipped lower, revelling in the darkening flush across the boy’s cheeks. He raised a knee on the large chair, smothering the Earl with his presence.

Lips crashed. The boy was so sweet, so soft and needy, he moaned even as the demon’s fangs broke his lip, bitter copper only making the kiss deeper.

“…Yes” Ciel gasped, oddly truthful as he caved beneath the demon. Embarrassed but horny, he pressed his hips up into the butler’s grip, desperate for more friction. Sebastian pulled the waistband of his shorts further down, giving the demon better access to his needy cock. The Earl groaned, legs spreading unconsciously as the butler took over jerking him off.

“If you wanted me, you need only ask” Sebastian breathed, eyes lidded. Ciel looked so tiny in this too big office, tiny in that massive chair beneath the butler’s looming shadow.

“Ah- please” Ciel huffed, little ring adorned hand pulling the demon closer, bunching up his flawless midnight uniform.

Sebastian stroked him firmly, cotton glove somewhat uncomfortable on the boy’s sensitive skin. The demon’s hungry lips captured his again, swallowing desperate moans and pulling at his bleeding bottom lip. Ciel gasped for air when they finally parted, Sebastian mouth trailing down his neck and leaving behind claiming bites that had him squirming all over again.

“Sebastian” the Earl’s breathing was rough, chest quickly rising and falling, “this is an order” finally the boy said those words Sebastian had been longing to hear all day.

“I want you to fuck me”

The demon’s eyes glowed a hellish red, excited and terrifying and oh so alluring. His grin was unnaturally sharp, a predatory look that promised the boy unspeakable pleasure.

“Yes my Lord”
