Anathema

Summary:

Barbatos is pissed at Solomon for summoning him.

Notes:

Hey! Obviously this is my first fic and my first time using AO3 properly. I tried to include all the glaring tags but I may have overlooked some unintentionally OR included some that shouldn’t actually be on there, if any of the two are the case then please don’t hesitate to let me know! Also, I might take requests if anyone reading has any.

To the people who want to skip straight to the smut just scroll until you see: ~~ and read what’s under it (there will also be squiggly lines when the smut ends).

This is inspired by how Barbatos acts towards Solomon in the early lessons of Nightbringer.

Work Text:

The air buckled as the summoning circle sealed shut.

Solomon straightened, his robes settling. When he finally faced Barbatos, his expression was perfect, lips curved to something that might’ve been a smile if it weren’t so sly.

“…You,”

Barbatos said softly.

“You deceitful, grasping imitation of a sorcerer.”

His eyes flicked over Solomon with disdain.

“To think you would dare pull me across realms like a misplaced trinket. Your audacity is almost admirable—“

Solomon winced theatrically, his hand pressed to his chest. He wasn’t truly offended, it was all theatrics.

“You really know how to make a reunion special, Barbatos.”

His fingers tightened at their side. The air around the two dimmed.

“Do not mistake my restraint for forgiveness.”

Barbatos continued, his voice still smooth despite his resentment.

“The last time you ‘experimented,’ I spent three days disentangling myself from a fractured ley line in the human world..”

Solomon’s grin widened, he was unapologetic in his attitude.

“Ah. That teleportation. See, I was going to apologize—”

Barbatos interjected.

“You were not.”

Solomon continued,

“—but now I feel like it built character.”

A sharp pulse of green demonic energy rippled outward. The message was clear.

Solomon dodged, his white hair swaying with each calculated step.

“Careful.”

He murmured, his dark blue eyes blazing despite his composed posture.

“You are standing very near the line between irritating and unforgivable.”

Barbatos met his gaze without backing away.

“Funny,”

He said, strained under all the tension.

“That’s exactly why you seem to like me.”

Solomon’s lips curl into a thin smile, his dark blue eyes glinting with amusement and hidden danger.

“Oh? Irritating, you say?”

He tilted his head, voice dripping with his fake sweetness.

“I could list every single thing that irritates me about you right now, Barbatos… but then we’d be here all night.”

Solomon’s fingers twitch at his side before he lifts one hand in an idle manner. Scratching his chin.

“Unless… that sounds fun to you?”

Solomon’s grin widens all while Barbatos' eyes narrow, irritation crossing his usually composed features. The green energy around him flares in response to Solomon's taunt.

"Fun?"

He repeats, voice dripping with passive aggressive disdain.

"You think this is some kind of game? You drag me here against my will and then dare to—"

Solomon cuts him off with a sudden chuckle, something about it was sharp and unrefined, nothing like the witty sorcerer he usually portrays himself as.

"Oh, but it is. Look at you."

He gestures at Barbatos

“That fury over being summoned by me.. Tell me honestly, do you ever get tired of pretending you don’t enjoy my company?"

Solomon leans in too close for Barbatos’ comfort (and far too casually for his liking), tilting his head like an intrigued child watching an ant under glass. Barbatos' entire form flickers with suppressed demonic energy, his voice dropping into something lethally calm.

"You mistake my tolerance for anything resembling fondness."

His hand lifts slightly, fingers curling as if resisting the urge to strangle Solomon right then and there.

"I have endured you only because I’ve a pact with you."

Solomon's grin doesn't waver, if anything, it grows sharper at Barbatos' restrained fury.

"A pact you willingly agreed to.”

He pointed out. Solomon knew he was pushing his luck.

"And if memory serves correctly, it is still in effect. You're bound to do whatever I command."

The smirk on his face was almost taunting now.

Barbatos' patience frays at Solomon's relentless provocation. He clenches his jaw, his powers flaring up.

"Bound to your commands, but not obligated to enjoy it."

He retorts, his usually composed voice strained. Eyes gleaming with barely restrained anger.

Barbatos' power surges suddenly, two chains seizing Solomon's wrists and binding them to the ground in a bind that radiated ominous and cold energy. They snapped into place around Solomon’s wrists and shoulders, this time pinning him mid-motion, anchoring him backwards to the floor with a weight that wasn’t physical so much as absolute. Solomon's smirk didn’t falter. In fact, he looked amused by this new development. His wrists flex against the chains hold, but they don't move an inch.

Barbatos stepped closer and loomed over only after Solomon was already restrained.

“This is me ending the conversation.”

Solomon didn’t struggle. An amused laugh bubbles out of him as he's pinned to the ground.

"Oh come on, no need to get physical."

He teases with an infuriatingly playful tone. His sharp eyes tracked Barbatos' every movement. Despite his playful attitude, something in his gaze was calculating, like a predator sizing up prey.

Barbatos stood over him, clearly irked by the audacity of this so-called 'great sorcerer' laying beneath him. Solomon, though restrained, did not look worried. Instead, a smirk still played at the corner of his lips, as if this situation merely added another layer of amusement.

“Can’t handle a little banter?”

Barbatos scoffs, his eyes darkening with annoyance.

"Your banter is nothing but a nuisance."

Solomon's smirk remains unbothered. He tests the binds again, and though they hold, he doesn't seem concerned.

"You know, for someone who hates me so much, you really put a lot of effort into binding me."

His tone is playful, almost mocking. Barbatos glares down at him, his patience wearing thin. Barbatos bristled at the teasing, his anger spiking again.

"What I can’t handle is you."

He leaned down, bringing their faces closer.

"You enjoy tormenting me with your incessant jabs at my patience. It’s as if it's a game to you."

Solomon laughs, the sound sharp and unapologetic.

"Maybe."

Barbatos’ entire body locks up. For one second, he doesn’t move. Doesn’t even blink. Then..

"You."

His voice is barely audible, thick with fury and sheer disbelief.

“You insufferable little worm.”

His hand snaps out to grip Solomon's collar and yanked him up just enough to slam their foreheads together hard. The chains tremble under the force of Barbatos' barely restrained power.

“I should rip your tongue out for that alone—”

“Barbatos, I think you’re forgetting something.”

Solomon’s voice is deceptively light, but there’s an edge to it, as sharp as the blade hidden in his sleeve. The chains tremble again, though this time not from Barbatos' fury.

"Forgetting what, exactly?"

Solomon tilts his head just enough for their foreheads to brush again, it wasn’t painful this time, it was more deliberate. A challenge masked as playfulness.

"The pact."

Silence seems to hang between them before Barbatos' grip tightens reflexively around fabric already strained by demonic energy residue from the restraints and then abruptly loosens when realization hits him. However, Solomon’s conniving voice broke him out of that.

“But to be honest.. I could not be bothered to stop you.”

Barbatos' entire body goes rigid, his grip on Solomon’s collar tightening to the point of tearing fabric. His free hand twitches toward Solomon’s throat before stopping abruptly, remembering their pact. A vein pulses visibly near his temple while his eyes burn. His free hand snaps up to seize Solomon's jaw instead, holding him in place with terrifying precision.

~~~~~~~~~~

Barbatos moved faster than a thought, his mouth crashing against Solomon’s in a brutal, biting kiss that felt more like punishment than anything else. It was all teeth and rage, his grip on Solomon's jaw tightened to the point of pain as if daring him to keep talking.

Solomon makes a muffled sound, it wasn’t protest but it wasn’t surrender either, before responding with equal fervor despite being the one pinned beneath him.

The chains shattered under sudden surges of demonic energy from both men as Barbatos finally pulls back just enough to snarl.

“Sham of a sorcerer.”

The air crackles with raw energy as the chains shatter into glowing fragments, their remnants dissolving like embers in the wind. Barbatos’ chest heaves. Whether from fury or something else? Even he doesn’t seem sure. All the while, Solomon licks his split lip slowly, his eyes were dark with amusement and genuine surprise. A slow smirk curls his bleeding lip as he leans up just enough to brush their mouths together again.

“…That—“

He murmured against Barbatos' lips,

“…was a terrible way to shut me up…”

Solomon hums, fingers threading through Barbatos' hair, yanking him back into another kiss. His fingers curled into the green strands.

"…You really hate me, huh?"

Solomon murmurs against his mouth, his breath warm. He sounds more intrigued than upset about the fact, in fact, he sounds downright entertained.

"I could list every reason."

He grits out, his voice low and taut. There is very real hatred burning behind his eyes, yethe was still here. Barbatos doesn't continue with words, instead sinking his teeth into Solomon's bottom lip, making him grunt. He uses the moment of distraction to pin Solomon back against the floor, his knee forcing its way between Solomon's legs as he loomed over him.

Solomon hissed in pain before grinning, shifting under Barbatos’ weight to grind up against his hip without a single ounce of shame.

Barbatos scowled at that, his free hand clamping down on Solomon's hip to still him. He had the advantage now. But Solomon's smirk doesn't fade, there's a hungry glint in his eyes as his own hands snake around Barbatos' back to drag him down until their torsos are against one another.

"You could."

He agrees too easily. He's still grinning, still arrogant even when beneath someone who genuinely despises him. It seemed to be Solomon's favorite state… though whether it was to irritate or excite Barbatos was impossible to tell.

Barbatos’ fingers dig into Solomon', like he’s considering whether to rip his ego clean off or simply combust from sheer outrage. Then he straddles him.

His voice is lethally quiet, eyes blazing with suggestive fury as he sits rigidly atop Solomon’s lap. Solomon just grins wider, hands resting casually on Barbatos' hips

"You look good up there."

His words are Provocative.

"…and If I didn't know any better, I'd say you were enjoying yourself."

His hands slide lower, gripping Barbatos' thighs like a vice to keep him in place. The weight of Barbatos pinning him down makes his grin border on smug as he grinds his hips up deliberately against Barbatos' rear.

Something in Barbatos snaps.

That smug expression of Solomon's flickers, slowly replaced by grunts that fade to a low groan as Barbatos grinds down hard against his hips in retaliation. His eyes gleam with unabashed challenge as he bucks his hips again, meeting the roll with unabashed impatience.

"Careful, Solomon the sorcerer.”

His fingers dig almost painfully into Solomon's clothed shoulders as his hips roll lazily to an agonizingly slow rhythm.

Solomon's smirk falters, an edge of something more raw cutting through. He grit his teeth, fingers gripping Barbatos' hips again in a silent warning.

"I’ve been told.."

"I'm not the…."

He paused as Barbatos rolled his hips in the same lazy, but no less infuriating manner. His hand tugs at Barbatos' belt, the other clenching around his hip

"...Most patient."

Not waiting for a response, Solomon yanks open the top button of Barbatos' pants, sliding fingers beneath his waist band to hook into the fabric.

"Patience…"

Barbatos repeats the word as if it's an insult, grinding down hard against Solomon's hips, his voice sharp with frustration.

"But Patience is not in your nature."

He says that but doesn't move away from Solomon's wandering hands, in fact he leans into them as Solomon's fingers slide under the waistband of his pants. Barbatos' eyes narrow in annoyance even as he makes a sharp and almost impatient sound.

"…Hurry up."

Solomon's eyes darkened at the sound, the hand resting under Barbatos' waistband sliding further in, fingers curling into his skin. He looks up at Barbatos, and his gaze is practically scorching.

"Say please."

Solomon drawls, his thumb running along Barbatos' hip bone in an almost teasing gesture, fingers pressing in just slightly. He knew Barbatos would snap him in half for teasing, especially now, but he couldn’t help himself.

Barbatos lets out a sharp, incredulous laugh. As if Solomon just suggested he beg for his life instead.

"Please? You insolent little—"

He snarled again, fingers twisting in Solomon's hair to yank his head back. His other hand slams down beside Solomon’s head as he leans in close enough that their breaths mix hot and uneven.

Solomon has to stifle a moan. There's a sharp, exhilarating thrill in being manhandled like this, in watching those dark eyes burn with nothing short of pure loathing. A thrill that makes him want to see how far he can push before he breaks. Solomon bucks his hips up to meet Barbatos with enough force to make his breath hitch.

"…Or what?"

He taunts,

Barbatos' eyes flash like a blazing bonfire, his hand grips Solomon's hair and pulls harder, forcing Solomon's head to crane back even more.

"...Or,"

His free hand wraps around the front of Solomon's neck. It stays loose for now, it was more of a threat than any real choke, just enough to make Solomon's breath hitch in anticipation.

"...I'll shut you up myself."

Solomon chuckles breathlessly, the sound half strained, his hands moving to rest under Barbatos' thighs and finally moves, slamming their mouths together with enough force to bruise both their lips now raw from teeth clashing too hard.

Barbatos lets out a sound that’s between a hiss and a growl, his hand tightened on Solomon’s throat before he took control of the kiss, all teeth and pure, seething hatred. Solomon's breath hitched as he responds with near manic fervor, shifting under the weight of Barbatos seated on his lap. His free hand took advantage of this, hastily unbuckling his own belt. Hands skimming over the silver metal. His hands are relentless, moving up and under Barbatos' shirt to pull fabric aside so he can drag his nails across the bare skin.

"…Barbatos.."

He murmurs against lips, his voice rough with need.

The sound of Solomon's voice, rough and urgent, only seemed to snap something further in Barbatos. He broke the kiss only to tear at Solomon's clothing, gloved fingers nearly trembling as he tore at the black fabric. Solomon's breath hitched as Barbatos yanked it clean off. Barbatos’ hands began roaming over the bare, heated skin with an impatient eagerness that only fueled the frenzy between them.

Solomon only grinned as he shuffled, pushing his black dress pants just low enough.

“It’s unfair I’m the only exposed one here, Barbatos.”

He made a gesture with his fingers, Barbatos’ shirt and pants suddenly off and neatly folded somewhere else on the ground. Solomon knew Barbatos had a bit of an affliction for germs, but that didn’t matter now.

"Shut up."

Barbatos speaks again and captures Solomon's mouth in another kiss. His leather-covered hand slips between them, wrapping around the hardness already straining against Solomon's briefs, stroking lightly as his other hand grips the back of Solomon’s neck enough to bruise.

Solomon's hand snaps out to behind him, wrapping around Barbatos' wrist. For a moment, it looks almost desperate.

"…Wait-"

He murmurs, breath shaky as his other hand tightens its grip on Barbatos. Barbatos stops but doesn't pull away, instead he leans in even closer until their noses almost brush.

"For once,"

He says, his voice a low growl, breath fanning Solomon's cheek. Solomon shivers, the sound causing something hot and desperate to coil in his stomach.

"Be quiet."

Solomon obliges. He swallows his next quip, eyes fluttering shut as Barbatos' thumb rubs a slow, maddening circle against the head of his length. Solomon groans, biting his lip hard enough to draw blood to stifle any further sounds.

Barbatos begins nipping at Solomon's jaw to make him lean his head back to expose more of the long line of his throat. Solomon obeys, tilting his head. Barbatos's tongue licks a path up the side, drawing a sharp inhale from the sorcerer. He sucks red marks into Solomon's throat, teeth sinking just enough to leave bruises like tiny brands.

Solomon can just feel the sting before Barbatos moves again, the hand still on his throat moves to his face, thumb running over his swollen bottom lip. Solomon smiles, and then..

Barbatos’ breath hitches at the sudden, and wet heat of Solomon’s mouth around his fingers. His pupils dilated further as he watched him suck with obscene enthusiasm. His other hand fists in Solomon's hair, yanking his head back just enough to expose the spit-slick trail of drool.

"Disgusting,"

He mutters hoarsely.

“You're like an animal."

But then Barbatos drags those same glistening fingers down over Solomon’s collarbone and back up, leaving a slick path.

Solomon grins and licks his lip.

"And you're enjoying it."

He retorts before taking the fingers back into mouth, sucking and swirling his tongue around the digits without a hint of shame. Barbatos feels his head spin when Solomon moans around his fingers.

"…Damn you."

Barbatos murmurs. He adjusted his stance, lifting his hips so he was no longer fully settled, hovering instead. He was in his demon form now, his tail tracing a slow arc through the air before dipping and stroking Solomon’s length. It was cool and wet.

Solomon's entire body jolts as the tail drags against him, coating it. His breath hitches. His fingers scramble at Barbatos' hips, nails biting into skin hard enough to leave crescent marks. Barbatos watches with dark satisfaction as Solomon struggles to keep quiet, the tip of his tail pressing just under Solomon’s length and giving a slow upward stroke. The sorcerer arches beneath him with a muffled sound, it makes something primal flare behind Barbatos' ribs.

Solomon's fingers trembled as they gripped Barbatos' sides. It was almost impossible to think, let alone to form words while Barbatos toyed with him so mercilessly. Every brush made his hips twitch as though he couldn't bear it, like he was on the very edge but Barbatos refused to let him slide over. Solomon's breath came in ragged pants, sweat beading on his forehead as he managed to grit out.

"…Enough."

His hand snaps to the base of Barbatos' tail and squeezes, tugging it away. It was an order. Solomon might be under Barbatos and naked, but he still had the audacity to try and call the shots. They had a pact, after all. Barbatos bristled like a cat.

"I'm not—"

He started to respond, about to give Solomon a sharp retort, but Solomon tugged on his tail again, harder. Barbatos' head jerks, voice almost breaking into a whimper. Solomon looked smug, the expression only making Barbatos angrier, and more turned on.

"...Let. Go."

Solomon’s smirk widened at the sound of his near broken whimper.

"Then behave."

His tone was low and taunting. It was rare to make Barbatos waver like that. Solomon knew it, and he was enjoying every second. Barbatos bristled again; he's about to snap something back when Solomon pulls his tail, again. Barbatos' body jerks with surprise and he lets out another low sound, one that might've been a moan.

"...what in the devildom are you—“

Solomon grabs Barbatos hips. Pulling him down and slowly easing him to take his length. Barbatos' body tenses as Solomon holds him in place. He glances at the demon, making sure there was no doubt or hesitation before continuing

"If you don't relax, neither of us is going to enjoy this."

He warns, his fingers running softly up and down against Barbatos' sides. Barbatos tenses, but the motion is soothing. His breath hitches. Solomon takes advantage, slowly guiding Barbatos lower, letting him feel every inch in excruciating detail. Solomon's other hand presses against his hip, keeping him there as they go.

Solomon’s fingers wrap around him, tight, deliberate. Slowly stroking him to help. Barbatos' entire body locks up the second he feels it. The gloves dig into Solomon's shoulders, A choked sound rips from his throat—

"You—"

He speaks but can’t finish because Solomon rolls his hips upward, taking him deeper in one smooth motion. Barbatos’ tail lashes wildly behind them as he grips Solomon like a lifeline. His breathing is becoming ragged now despite how much he wishes to pretend otherwise.

Any words are now strained out between gritted teeth even as his hips move forward involuntarily against theirs own momentum alone

Solomon watches with an almost predatory satisfaction as Barbatos comes undone. his claws digging into Solomon’s shoulders, his breath hitching in sharp little gasps. The way Barbatos shudders around him is almost too much to bear.

"You hate me so much…"

He murmurs

"And yet here you are."

His hands slide up Barbatos' back until they tangle roughly in his unruly hair and pulls.

"Taking it all.”

Barbatos slams down onto him, taking him to the hilt in one brutal motion. The force of it knocks the air from his lungs, leaving him gasping and writhing beneath Barbatos' weight.

His hands fly to Barbatos' hips, fingers digging in hard enough to bruise as he tries (and fails) to adjust. Every ragged thrust sends sparks up his spine; every snap of their bodies together punches another noise from his throat.

"Is this what you wanted?"

He rasps between sharp breaths, unable to keep himself contained any longer.

Barbatos' entire body locks up, his tail lashing wildly as he feels Solomon bottom out inside him. His breath comes in ragged, punched out gasps, his claws digging deeper into the sorcerer's shoulders like he’s trying to ground himself.

A hoarse, strangled sound escapes Solomon’s lips as Barbatos slows to a stop him. He throws his head back and closes his eyes, gasping for breath and trying not to lose what's left of his composure.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

"I— ah— Barbatos…"

He stammers, his voice hoarse and choked with barely restrained need. His thighs tremble with the effort to keep himself pinned to the ground and not buck up against the weight of Barbatos who’s still in his lap. When he opens his eyes again—

“Barbatos—?

Solomon blinks, now reeling from the sudden loss of contact, his lips part to gasp. It takes him a few seconds to gather his bearings and try to comprehend what just happened. He opens his mouth to speak, but the words die in his throat as he takes in Barbatos' demeanor. There is a change in his stance and the way he's now completely clothed has Solomon's brain reeling.

When did he get off him?

How were his clothes on so fast?

"Wait a second—"

“Begone.”

The world around Solomon spun for a moment.

Solomon finds himself suddenly alone in a vast and deserted building. For a moment he sits frozen in place. His mind is still struggling to catch up with the turn of events. He looks around, hoping to catch a glimpse of the demon who abruptly vanished. However, he is alone. Alone in the endless hallways of this place.

At least, that’s what he thought.

The ground shook for a moment. What appeared to be a snake slithered closer, and fast. What he thought was a small snake was in fact ginormous, and coming closer with murderous intent.

The underground labyrinth.
