sebastian sewing ciel's outfits himself, never letting his little master know he's the one making them. that way, he can put ciel in whatever pretty clothes he wants, and if the boy happens to dislike some of them for being a bit over the top, sebastian can just blame it on the "seamstress" his master thinks they've hired.

Anon was SO right. Beast is why Ciel goes after Arthur so hard in BoM. So pissed about his butler manipu-fucking a woman that he’s putting his entire manor on lockdown and forcing Seb to play dead while he fawns over this random author like no other. Yes you HAVE TO bring me a note in a pillow while I’m chained in bed with him, otherwise how else are you going to witness him watching me with desire in his heart.

Doubly so this is why Sebastian couldn’t help but tip Arthur off. He NEEDED an excuse to take off the mask and terrorize Arthur in demon form.

Love the idea of Ciel and Seb putting each other back together aboard the rescue ship after the Campania sinks. Ciel insisting upon cleaning Seb’s wound, putting ointment on it, and wrapping him in bandages, even as the demon insists that he’s fine and that Ciel need not fear for him. But Ciel can see the tightness in Seb’s face, the awkward way he’s holding himself; he can hear Seb’s stifled grunts and moans of pain. And so he makes it an order- sit still while I tend to your wound because you are mine, you said, down to the last hair upon your head and I will tend to what is mine. And so Seb complies, wearily and with a strange and foreign warmth in his chest, biting his lips bloody as his prey washes and binds the near fatal wound that very well could have freed said prey from his grisly fate. Such an odd boy.

Then, after his little lord has slipped a clean, borrowed nightshirt over Seb’s head and declared him free of the order to sit still, it is finally the demon’s turn to tend and clean and touch his master. Bruised and covered in demon blood but largely unscathed. Cold. In need of warming but Seb is full of warmth and he holds his bocchan tightly after washing him and draping him in a matching nightshirt. The bruised ankle he ices though to lower the swelling. He’s thankful it’s not broken even if that would have given him the perfect excuse to carry his master around for weeks.

They sit, then lie together in bed. Their foreheads touch, followed shortly by their lips and tongues. The rhythm of their mouths matches the rocking of the ship as it hurtles through the night back towards London. It’s not long before they both fall asleep, safe in each other’s arms.

i need sebaciel to be as unhinged as possible. fucking right in front of the people they’re about to kill. sebastian piercing them with his tentacles or crushing their heads, seconds before ciel cums, because only he has the right to see him like that. both splattered with blood, but never stopping moving, ciel cumming at the bodies lying before him

[thatbutlerhorny]

once sebastian gets started, he can’t stop himself. he wraps his tentacles around ciel's calves, holds both his wrists pinned above his head, and sucks on every inch of skin. he sucks on his nipples until they’re so sensitive they actually hurt. he leaves rows of bite marks on his thigh and bruises on his hip. he makes ciel come at least a few times just from the caresses alone, before he even touches his cock or his hole. only when ciel starts shedding tears from being overstimulated does he prepare and enter him, not stopping until ciel orders him to.
