Metallic Taste

Summary:

Ciel is in a horrible mood while coming down with a cold. Sebastian can't help but enjoy getting on his bad side.

-

Ciel wasn’t going to settle for merely pistol whipping a demon once, not with Sebastian’s insolence and his own wrathful mood. He gently stroked Sebastian’s cheek with the barrel of the gun, cold eye fixed on Sebastian’s face. “Are you going to behave?”

The way Sebastian saw it, he won whether Ciel tried to punish or reward him.

Work Text:

There were some children who wanted coddling when sick. Comfort, being read to, having their favorite treats… Sebastian’s master was nothing like them.

Well, Ciel liked his sweets.

He made his demands with all the gentleness of an agitated wasp.

Ciel coughed weakly to himself as Sebastian pulled his shoes off. “This is ridiculous,” Ciel wheezed. “I have several meetings today. The deal with the new dock overseer—”

“He would laugh in your face should you confront him with sniffles and a sore throat, my lord.” Sebastian effortlessly dodged a moody kick to his face, unfastening Ciel’s stocking garters. “The sooner you rest, the sooner you are able to have a dignified meeting.”

“Hmph.”

Ciel folded his arms, watching Sebastian undress him at 2pm with contempt. The skies outside were grey, rain drizzling down only to create an even duller brown slop of mud to reflect the dreary skies. “You enjoy this, don’t you?” he spat. “Allowing such a mild ailment to take me out of commission.” Ciel coughed again, directly at Sebastian, not bothering to cover his mouth.

Sebastian smiled to himself. “I do.”

“Augh!” Ciel dove forward, slapping Sebastian across the face. “Insufferable!”

Sebastian raised his eyebrows, expression unchanged. He didn’t even allow his skin to redden from the strike. “Did you intend to rattle me? It’s nothing of note, coming from such frail strength as yours.”

Ciel’s face darkened. “Oh?”

“Hm.” Sebastian continued to roll his stockings off. “As you are, there is nothing you could inflict upon me with your own hands that amounts to more than a breeze.”

“Demon.”

“Grown-up is more like it.”

Sebastian had no reason to rile his little master up aside from sheer boredom, but Ciel rose to the occasion with all the predictability of the tides. Ciel seethed, choking on air. Perhaps it was playing dirty to rub dirt in old wounds, conjuring up the most detested aspect of those who’d ever hurt Ciel, but it wasn’t as if Sebastian had a conscience to care.

“I’ll make you choke,” muttered Ciel.

Sebastian set his stockings and shoes aside, still kneeling. “With what?” He inquired politely.

Another strike to his face was expected, but the material and force of it was a surprise. Sebastian blinked, tasting blood and metal. He examined the object in Ciel’s hand— the pistol he normally kept under his pillow. “I see.” Sebastian was impressed. “There is nothing so inspiring as wickedness, is there?”

Ciel wasn’t going to settle for merely pistol whipping a demon once, not with Sebastian’s insolence and his own wrathful mood. He gently stroked Sebastian’s cheek with the barrel of the gun, cold eye fixed on Sebastian’s face. “Are you going to behave?”

The way Sebastian saw it, he won whether Ciel tried to punish or reward him.

“Are you going to shoot me if I don’t?” Sebastian yawned, showing off his sharp canines. “You know full well it will only be an annoyance to clean up.”

Of course, that could be reason enough for Ciel to empty the chambers. Petty little brat.

Ciel surprised him again.

Sebastian gasped, his hair roughly grabbed by Ciel’s fist. He yanked on Sebastian’s hair, grip close to the scalp as he forced Sebastian’s head back. The pistol remained close to Sebastian’s face, his mouth lax. Sebastian licked his lips, eyes flashing red with understanding. “Hmm. What next?” crooned Sebastian.

“Isn’t it obvious?” Ciel smirked. “Are you enough of a pervert to get off from this, or have you finally found some shame?”

“It’s up to you to test that, isn’t it?”

Ciel had to scoot closer in order to reach as far as he wanted, which made Sebastian huff with a laugh. Ciel jammed the pistol into Sebastian’s mouth, cutting off his sound. Sebastian gagged, as promised, eyes widening as Ciel roughly thrust the tip against the back of Sebastian’s throat.

“At least it gets you to shut up,” grumbled Ciel. He breathed harder as he watched Sebastian shiver. Ciel angled the pistol in better, never fully pulling it out as he fucked Sebastian’s throat with it— truly the first time he’d managed to fuck anyone with anything— unsympathetic as Sebastian coughed and wheezed. 

Sebastian was enthralled. He let himself fully sink into the dark enjoyment blossoming in his chest. He let Ciel hold his head still, obediently swallowing and gagging in turn as Ciel haphazardly, cruelly ground the metal inside of him, moaning around the painful intrusion. It was easy to give into his base desires, programmed to find a fascination and eagerness within him for whatever his contracted master enjoyed.

No, it wasn’t enough.

He closed his lips around the pistol, going so far as to flutter his eyelashes at Ciel as he sucked on it, boasting what he could do if his little tyrant had something else that could breach his throat.

Ciel panted, face pink. “Whore.”

Sebastian opened his mouth, letting the gun slide out, saliva trailing from the tip of it to his lips. “It’s mutually pleasant, I see.”

He let his voice sound husky, advertising what he’d let Ciel do to him. Sebastian had no need to let his sex react to anything in the human realm, but he allowed himself to be half hard in his slacks, wondering how far Ciel would go.

Apparently, Sebastian had read Ciel’s horrid little mind.

Ciel stood up, one foot landing on the floor, the other coming down directly between Sebastian’s legs. Sebastian inhaled, chuckling when Ciel raised his eyebrows. “Yes, young master?”

“You really are a harlot.”

“I only aim to serve.” Sebastian stuck his tongue out, licking a stripe up the length of the pistol. “Your command, my lord?”

Ciel glared down at him. “Would you enjoy this? Finishing under my foot, gun stuck in your mouth?”

Sebastian kissed the tip of the gun. He hoped even Ciel’s weak senses could pick up on his dick pulsing under the sole of Ciel’s foot. “The more you try to repel me, the more I am drawn to your sadistic whims, young master. It’s only my nature.”

“That’s a yes, then.”

Ciel leaned forward, placing all of his weight on the foot between Sebastian’s thighs, thrusting into Sebastian’s mouth at the same time. Sebastian took it all, groaning with genuine pain and pleasure as Ciel ground his heel down against his cock. Ciel seemed to have figured out a rhythm for his unnatural motions for face fucking Sebastian, arm and wrist twisting harshly as the taste of metal and soot mixed with Sebastian’s spit.

So close to his master, his little corrupted, sinful thing, Ciel’s rich scent filling his nostrils as he did his damndest to wring reactions out of Sebastian, it was all so much, and he had to reward the boy when he did something well— 

Sebastian came, bucking up against the foot uncomfortably grinding down against him, wetly coughing around the pistol shoved deep in his throat.

Ciel stepped back, pulling out the gun without care as it clacked against Sebastian’s teeth.

His face radiated disgust.

His body was flushed all over, aroused at the sight of his butler, submissive and kneeling with ruined trousers and a split lip, hair limply falling down against his forehead in clumps.

Sebastian smiled, licking his lips again. “Well, young master? Ought I attend to you next?” he purred.

“No.”

Sebastian paused. “Oh?”

Ciel crossly sat down on the bed, tucking himself into the covers and hiding his red face. “I would never be drawn to such a sight. Go make yourself presentable and leave me alone.”

“Are you certain? I—”

“Go.”

An order was an order.

Ciel knew it was no secret. Somehow, that made it even better, to know that Sebastian was aware of everything he did. It was even more exquisitely frustrating as he waited for Sebastian’s footsteps to fade away, to take himself in his own hand and give himself an incredibly unsatisfactory orgasm, gasping as he couldn’t think of anything else but Sebastian, even with his eyes screwed shut. He groaned into his pillow, thoroughly winded and coughing again from the slightest exertion, barely able to enjoy the blip of an afterglow he got.

His pride would cave. He knew it would, but Ciel would put up a fight before he deigned to beg the demon for anything.

Just because he knew how the game went didn’t mean he didn’t give it his best shot at resistance every round.

Sebastian waited out of human earshot, chuckling to himself and shaking his head, presentable from the second he’d left Ciel’s room.

Children were impatient. Sebastian wouldn’t have to wait long for his call.

Notes:

"What if Ciel fucked Sebastian's throat with his pistol" that's it that's the fic lmao. Needed it out of my head so here we are.
