Tear you apart

Summary:

How exactly do you get the Radiodemon to sign themselves away for all eternity?

Aka- a flashfic about masochism and power dynamic switching that, again, got out of hand!

The violence tag is there for safety, but most of the worst things do happen off screen/aren't too graphic. And it's all very enthusiastically consented to 👌

Notes:

I've been on a big 'She wants revenge' kick so Tear you Apart was a perfect title to borrow 😉

Thanks to Akire for the original prompt 'Contracts', I hope it delivered!

(See the end of the work for more notes.)

Work Text:

When Alastor blinks himself awake, he has no idea where he is.

He’s disorientated, but he manages to force his eyes to focus just as his smiling mask slips back into place. From what he can tell he’s sitting on a small chair in the center of the room, or rather, he’s bound to it. The room itself is unrecognisable with how starkly it’s decorated, and how little light it filters in through the tiny gaps around the entrance. To anyone else, the stark red hue of the light would be alarming, but to Alastor, it’s a strange comfort.

At least he’s still in Hell.

He doesn’t get time to recuperate when a slight shift in pressure alerts him to another presence in the room. He holds his breath, flicking his ears backwards to try and amplify the sounds of their slow approach as a softer smile creeps onto his face. Again, any other demon would be alarmed by the sense of someone watching them. Especially if that someone is likely their captor, the one who had taken him from those plush red sheets and strung him up in Satan knows where.

Alastor isn’t because he’s almost certain he recognises the particular click click click of steel-toed boots on the hard floor.

It does little to stop the full-body shiver travelling up his spine when black gloves dance around his shoulders, teasing at first, until his chin is grabbed and forcibly tilted backwards. How could he not be affected when he sees his lover’s soft yellow eyes and formidable grin light up, just for him?

“Ah, Lucifer.” Alastor says in the most level tone he can muster over the sound of his heart pounding in his chest, “Why am I not surprised?”

The King tilts his head at a seemingly strange angle from Alastor’s point of view, obscuring his face further in the already dim lighting.

Not enough to conceal his quivering bottom lip though.

“Not even a little?”

For the second time that night, Alastor feels his heart rate increase. He struggles against his bonds, instinctively trying to break free despite knowing Lucifer wouldn’t be careless with the ties. Not after the last time. When they’d played a similar game and Alastor had broken free effortlessly, tying up Lucifer in return until he was screaming for mercy.

And then begging for more.

While neither of them had any complaints about the switch, Alastor knows that glint Lucifer’s eye means he’s in a very particular mood tonight.

He shifts in his chair for entirely different reasons, clearing his throat loudly before daring to speak again.

“Well, you managed to capture me when I was asleep. With my guard down, nonetheless. Take of that what you will-” Alastor narrows his eyes at the King’s growing smile before continuing, “-But when it’s your bed I was resting in, I doubt that amounts to much.”

A thousand emotions wash over Lucifer’s features, the trap well and truly fell for. A small voice in the back of Alastor's head tells him he’s playing a very dangerous game. That despite their familiarity Lucifer has the power to end him in an instant if he wants to.

But it’s that thrill that ensnared him in the first place, the one that made him break every vow of solitude and freedom he made to himself.

It’s the flicker of genuine affection in those cherubic features that has him coming back again and again.

It’s short-lived. Lucifer’s expression literally darkens, an inky black shroud creeping over his features. The only thing Alastor can see clearly now are his eyes, far sharper than usual, boring into his very soul.

“Enough.”

There’s a snap of fingers but it’s drowned out by Alastor’s startled gasps as the rope around him multiplies and weaves around his already bound form. The strands slither around his body like snakes, wrapping around themselves and his limbs to bind him further. His instincts tell him to fight it, to try and escape, but he resists with every fiber of his being.

As dangerous as Lucifer is, Alastor trusts him. Far more than The King knows and a hell of a lot more than he’d ever admit out loud.

Or, at least, that was his stance until this moment. Not only is the tightness and security of the rope already shifting his mood, but he knows exactly why Lucifer is doing this even before he opens his mouth.

It’s something that’s been a long time coming, that he’s dug his heels in about over and over again.

Something Lucifer has finally figured out he needs his hand ‘forced’ to do.

“Do you know why I brought you here, Alastor?”

Lucifer’s voice is much more level than his usual tone and that alone does things to Alastor that he can’t quite fathom. With the rope still tightening around him and the long fingers drifting down towards his neck, he can’t hide the way he’s already shaking.

It’s one of the reasons he knows the outcome of tonight, even before they’ve started.

The journey, however? That’s a path he can’t quite see. But he's tingling all over in anticipation for it.

“I have a hunch,” Alastor eventually replies when his voice is steady enough to mask just how affected he feels, “But you know where I stand on that matter.”

It’s as close as a confirmation as Alastor is willing to say out loud, especially when he’s already sidestepping actually saying no.

It’s been an ongoing saga for close to a year, ever since Lucifer floated the idea of having Alastor’s soul bound to him through a demonic contract. It wasn’t unusual, in fact, he already had most of the powerful overlords in the seven circles tethered to his service in one way or another. But they were either former angels that had fallen with him, or they were hell-born and in service to him from their birth.

Alastor on the other hand is neither, and he has no obligations to sign himself away. King or no.

But…

“I do.” Lucifer says, interrupting his train of thought, “And I respect why you’ve avoided giving yourself to me fully so far-” His fingers move lower, trailing down Alastor’s sleep shirt to pop the top buttons open, giving him more access to his throat, “-But I’m feeling a little more persuasive as of late.”

The tips of his elongated fingers dig in, a perfect reproduction of where Alastor’s claws have previously bruised Lucifer’s alabaster skin. There’s a little hesitation until Alastor gasps and his smile wavers, swelling the King’s confidence. The grip tightens, stealing away Alastor’s ability to breathe while his radio crackles wildly. Stealing the breath of others is an entirely different thrill, the struggle of one of his favourite things to see.

But something has to be said for experiencing it from the other side.

Alastor’s whole body is tingling in moments, skin prickling with heat as his cheeks flare red with arousal. The rope intensifies everything tenfold, removing his ability to struggle. Not to mention the two ends weaving higher, dangerously close to where Lucifer is choking him out. His vision blurs at the edges the longer he’s deprived of oxygen, the pain of his straining lungs impossible to ignore.

Just as it tips over into too much, when Alastor feels the unfamiliar but oh-so-delicious tingle of fear down his spine, everything stops and he’s filled with a different kind of sensation. Warmth blossoms from his rapidly filling lungs as he gasps for air and spreads outwards, filling him with a mixture of pleasure and tiny pinpricks of pain as sensation returns.

It’s euphoric… but nowhere near enough to sway him. Not when he knows just how much further Lucifer could go if he was only given the chance.

“What-” Alastor starts, coughing when his voice comes out as a garbled static mess, “What can you possibly offer me that I don’t already have?” He dares to look up, locking eyes with his captor before dragging his tongue over his sharpened teeth, “Or that I can’t take by force?”

Alastor knows exactly what he’s doing. It’s this level of charm and commanding attitude that usually makes Lucifer fold. That makes him willingly hand over the reins and put his everything into Alastor’s hands.

What he doesn’t account for is Lucifer somehow looking even more emboldened than before.

“Oh, Alastor.” He chuckles, dropping down so that his mouth is level with one of Alastor’s twitching ears, “How little you know.”

Alastor isn’t given time to quip back before his neck is jerked to the side, exposing his nape to the literal devil on his shoulder. He tries to keep his breathing steady, but it becomes increasingly difficult as Lucifer’s hot breath draws closer and closer. Shielding his telling eyes with his hair isn’t difficult, but there’s no hiding his shiver when Lucifer’s tongue makes contact with his skin.

Still, Alastor has to give himself some credit. His smile doesn’t waver until Lucifer’s teeth break his skin.

There’s no shame in the groan that escapes his lips, not when the dual sensations of sharp pain paired with being stimulated in such a sensitive area are driving him insane. Alastor is both kicking and thanking himself for the slipped confirmation over how surprisingly sensitive his neck is. Especially around the scar Lucifer’s teeth are currently threatening to break open.

Again, it’s doing far more for him than it probably should. But for all these theatrics it’s nowhere near enough.

“While this is pleasant, Sire,” Alastor hums as Lucifer makes quick work of the rest of his buttons, opening his shirt as best he can with the rope, all while preparing himself for more contact the longer this ‘persuasion’ goes on, “This isn’t exactly something I’d sign myself away for. It’s-”

He’s cut off by choking on his own breath when Lucifer’s hand, now ungloved, rakes down his exposed chest. The scratching alone would be enough to make him stumble, but that’s not the sensation he’s feeling. It’s like he’s being burned alive from the inside out with the level of white-hot pain stealing every inch of his attention.

Far too quickly Alastor jerks his head down, expecting to find his flesh flayed open, only to find only three small welts are running down his torso.

Lucifer chuckles darkly in his ear, “You were saying?”

“What was that?!” Alastor demands, desperately squirming against his ties.

He fruitlessly tries to cross his legs when Lucifer circles around him, another instinctual effort to compensate for just how little his sleepwear is hiding. It’s useless since as soon as Lucifer comes into view properly his eyes flicker downwards, almost comically widening at the straining tent.

Alastor catches the tiniest trickle of drool down Lucifer’s chin and practically throbs at the sight, just as turned on by the effect he has on his partner as he is from the still prickling pain.

“Just my fingertips,” Lucifer finally answers when he stops staring, twirling the offending digits in the air, “Though I am tapping into my latent Angelic judgement powers, it takes a bit of effort nowadays but you’re worth every second-” His eyes flick upwards, catching Alastor’s uncharacteristically blown out pupils with his own calculating gaze, “-The depths of your sins run quite deep, don’t they, Alastor?”

Again, Alastor shivers. He’s starting to feel the pull to give in, and it’s barreling into him like a freight train. He clears his throat several times while he tries to catch up and tries not to beg for that touch again and again.

Instead, he clutches at any straw he can-

“Why have you not done this sooner?”

-unintentionally giving himself away even further, demonstrated by the widening smile in front of him.

“And miss the look on your face right now?”

Lucifer laughs, clicking his fingers to magic away every scrap of Alastor’s clothing.

And his own.

Alastor would be lying if he said he didn’t immediately devour every inch of Lucifer’s pale flesh with his eyes, having to consciously fight back the growl over how faded his previous marks currently are.

“Sorry, my love-” Lucifer purrs, straddling his lap without a second’s hesitation, “I’m enjoying this far too much.”

“But- we could have-” Alastor gets cut off again by the feeling of his cock being engulfed by an incomparably tight heat, “Lucifer, be cautious or you’ll hurt-Oh.”

Lucifer doesn’t stop sinking down until Alastor bottoms out, silencing him by those same burning fingers clutching at his throat. The combination is almost too much, especially without the use of his arms. The rope burns whenever he struggles against it, adding to the sensations overwhelming his already trembling body.

He’s struck with the fleeting notion that he can’t remember the last time he felt so alive. Not to mention the level of connection he feels to the demon he’s buried inside being unlike anything he’s ever felt before.

And if this is how intense it can be without their souls being bound by contract, he’s absolutely going to kick himself later for causing such a fuss.

“Mind-blowing isn’t it?” Lucifer rocks himself in Alastor’s lap a few times before dropping his voice down to a husky whisper, “You want to know the best part?”

Not trusting himself to speak, Alastor huffs. He nods his head while biting his lip until it bleeds to keep himself from crying out.

“I have healing powers too. Not as powerful but-” He spreads his palm wider as an ice-cold stab pierces Alastor over the marks on his chest, “There we go.”

There’s no holding back the piercing scream that spills from Alastor’s lips as he watches the marks disappear right before his very eyes. Lucifer doesn’t give him a chance to recover before the hand wraps back around his throat, healing the marks left there.

To Alastor it’s like every nerve in his body is set alight with the most excruciating pain from the simple touch alone, to the point where he has to fully split his lip to hold off from spilling inside Lucifer far too soon.

While he knows it would be taken as a compliment, it doesn’t seem fair.

Not when the, thankfully still, demon in his lap is doing everything he can to drive him completely insane.

“How does that hurt more?” Alastor eventually rasps out, “It’s incredible.”

“Isn’t it just?” Lucifer rolls his hips until Alastor is practically gnashing his teeth before leaning forward to graze his teeth on the unmarked side of his neck, “-I could take you apart for days and never leave so much as a scratch.”

It’s purred so perfectly before his forked tongue darts out to taste the sweat on Alastor’s neck, a move so incredibly sensual that he’s hurtled right back to the edge again.

Only this time, with the way he’s shuddering and riding him as hard as he can, Lucifer is right there with him.

“Wouldn’t that be fun?” Lucifer chuckles, sinking his teeth into Alastor’s neck just as he drags both hands down his sides, leaving angry welts in their wake.

Alastor thrashes, tasting his own blood on his tongue as the rope feels like it digs into every inch of his skin.

Yes.”

“Pity-” Lucifer stills completely, almost looking like he’s about to move off Alastor’s lap completely, “-It’s not really appropriate to do things like this with someone I have no connection to.”

Alastor snarls, his more demonic form flickering into existence as his antlers creak with unnatural growth, “We’ve been in a relationship for ten whole-”

He catches himself when he looks up at Lucifer’s face. The level of understanding in his surprisingly soft features is startling. He’s always seen through Alastor like a pane of glass, but that sentiment has never felt more true than in this exact moment.

Lucifer knows exactly why Alastor has held back on signing himself away, even if the words have never been spoken aloud.

That doesn’t stop Alastor’s disjointed rant from tumbling out of his massacred lips.

“-I can’t. It’s- what if you decide you no longer want me- I couldn’t- I’ve never-”

“Alastor- '' Lucifer hushes him by cupping his cheeks, his touch momentarily returning to a normal temperature, “You think I wouldn’t offer my protection if I wasn’t deadly serious? I can give you everything you’ve ever dreamed of. The powers, the coveted position, the adoration you crave.”

Lucifer leans forward, capturing his lips in a short but passionate kiss that Alastor returns tenfold, pouring everything he can’t say into those precious few moments where they’re connected in so many more ways than one.

When they part Lucifer’s eyes are glassy as they meet his own, the sight of his lover just as overwhelmed as he is difficult to put into words.

“I hope you know that adoration will be from myself, too-” Lucifer adds, his previous bravado burnt to ash, “I’ll be just as much yours as you are mine.”

Surprisingly, the words flow from Alastor so much easier than any of the ones beforehand, “I’m yours.”

In a matter of seconds, Alastor’s arms are freed and placed upon the scroll Lucifer rests on his chest.

The dotted line poetically right above his heart.

“Sign here, my love-” He hisses, his serpentine features so much stronger in the presence of the demonic powers in his contracts, “And I’ll give you everything you desire.”

Alastor is halfway through signing his name when the inflection hits him. Not quite believing it to be true his eyes dart upwards, only to have his heart stop

The one thing he’s asked for constantly, the one thing Lucifer refused to give him despite saying he could take him to the brink and save him at the last second.

Alastor’s need to experience intense levels of pain was there in life, but in his remarkably quick death, some wires became crossed. To the point where he fantasises about being pushed to his limits, to have his flesh pierced and torn apart, just like he did to his victims. The scars he bears are a constant reminder that he’s not earnt a single one himself.

“Everything?” Alastor tries to clarify over the sound of his thundering heart as he finishes signing himself away to the only other being who understands the darkest parts of his psyche, “You mean?”

“Of course-” Lucifer waves away the contract, his yellow eyes flaring with hellfire as it’s sealed out of sight, “Now you belong to me, I can safely tear you apart” he leans in, licking the flowing blood away from Alastor’s lips until his cock throbs inside him, “Do you trust me to put you back together again too, love?”

Again, there’s no hesitation on Alastor’s part, “Yes.”

Three things happen in quick succession.
Lucifer turns his hand, his burning touch finally breaking the skin in Alastor’s chest cavity to drench them both in his blood.

Alastor’s freed hands fly to Lucifer’s hips, grip bruising as he comes with a deafening shout, quickly painting his insides and thrusting rapidly with any friction he can gain.

He collapses forward, passing out to the most intense pain he’s ever felt while his lover shudders in his grasp.


When Alastor comes too, he’s back in Lucifer’s- no- their bed.

His immediate reaction is to seek out the wound in his chest, startled to find he’s completely healed. Well, almost. Either by luck or with a very precise level of magic from Lucifer he can feel a new scar over his breastbone. It’s smoother than the others, but it’s there. The proof that what they did wasn’t just his fantasies getting away from him.

And, if Alastor needs any further confirmation, the beaming grin from the end of the bed is a rather good indication that it definitely wasn’t in his head.

“I’m sorry I didn’t figure out that little trick sooner,” Lucifer giggles, sliding on the bed to kiss Alastor’s cheek before handing him a hot drink, “Who knew all it would take for you to be mine was a little pain and some light bondage.”

Alastor rolls his eyes, momentarily biting his tongue.

Immediately realising he has one final card to play.

“Sire, I would have gladly signed that contract months ago when you first drafted it up,” He purrs, returning the kiss with a less chaste one of his own, almost spilling his drink when Lucifer whimpers needily, “But where would be the fun in that?”

It takes a few seconds of rapid blinking for Lucifer to realise before his expression darkens once more, “You tricked me?”

“Is it really a trick dearest one if it’s something I knew your black little heart wanted?” Alastor counters, setting his drink down to pull Lucifer into his lap in a mockery of their position last night, “Did you not crave the feeling of using your powers of seduction to ensnare me properly?” He teases, kissing Lucifer’s bare neck in between his words, showering him with affection, “And did you not enjoy every second?”

There are only a few more seconds of pouting before Lucifer melts into the embrace, whimpering and gasping at every kiss and tease of Alastor’s teeth.

“I loved it-” He eventually says with a heavy sigh, taking Alastor’s face in his hands again as he gushes without holding back, “And I love you, so much.”

“I should hope as much, since you now own me for eternity-” Alastor winks, placing a kiss against Lucifer’s palm, “-mon amour.”
