#36 of The Devil's Plaything

Chapter 21. Demiurge experiences his second Rut. Who better to practice tying with than his brother Malphas?

This chapter contains knotting/tying, scenting, aspects of ABO and homosexuality. The next chapter will contain heterosexual knotting.

Demiurge (C) Overlord

Malphas (C) Belongs to Me


There was no way he could sleep after that. He lie awake next to Lillith staring up at the ceiling while she slept soundly, as he had been for the past fours hours.

Everything had changed.

And he felt like the foulest kind of monster; unclean and unworthy...emerging from the darkest circle of Hell and into the sunlight for the first time. He felt...pierced clean through. He felt as though he had touched, no, defiled something sacred. Which, normally is something he would take extreme pleasure in...but no, this was different. It felt...wrong.

'What the fuck?'

Since when did he feel any sort of sense of morality?

He briefly glanced at Lillith's sleeping form next to him. She was curled up in a ball and facing away from him, and there were deep red grooves carved into the pallid flesh of her back where he had raked his talons downward the throes of passion. They had stopped bleeding hours ago, and would certainly scar if he did not give her a healing potion tomorrow. They were not lethal in the least, and she had wanted it rough...and yet, a small pang of guilt rippled through him, knowing he had hurt her, and that she would definitely feel pain when she got dressed in the morning.

'Why the Hell should I feel guilty for it? For fucking her hard like she asked?'

Demiurge was an Arch Devil. He got hard off of desecration and thrived on corruption. Why should he feel bad about fucking her senseless and drawing a little blood from her in the process?

He did not understand it; regret? Remorse? Whatever it was, this-this new feeling, it perplexed him at the deepest level and it made him angry.

He huffed through his nose in frustration, and propped himself up on his elbows as he pulled the sheets over her, partially to hide the damage he had done to her, partially because he didn't want his pet to get cold.

'You simply care about your pet. It's normal to develop sentiment for something you tend to everyday. Lots of people love their pets. They are emotionally supportive and can aid in dealing with daily frustrations.' He tried to rationalize.

But his logical, more blunt voice couldn't allow him to deceive himself.

'She tends to you , idiot. She's your fucking personal servant, above all, your sex slave. She's a traumatized brothel worker you saw as easy prey and after your last 'toy' failed to fall in line and obey or be any fun you projected all of your rage and hatred for her failure onto Lillith. And what did Lillith do? She took it in stride and stood strong through your psychotic storm until you finally got your shit figured out, and ended up enjoying all of the sexual abuse you put her through. Because Stockholm's Syndrome was the only way her mind could rationalize her situation so she wouldn't shatter and implode in on herself from trauma.'

She ended up falling for the monster that captivated her. Because she didn't know any better. Humans are far too easy to take advantage of, especially for a conniving and calculating creature like himself.

'I can be better...I can try to do right by her from now on.'

He wondered if it were remotely possible that Lillith might ever be enough to scrub the stains from his blackened soul.

No. Nothing could ever do that.

Just because he desperately wanted something to be true, did not mean it was. Demiurge was nothing if not realistic.

The Arch Devil knew himself better than anyone; his brother Malphas being the only other who truly saw him for what he was. He was possessive, dangerous, manipulative, violent, temperamental, and selfish. He expertly used these attributes to serve Lord Ainz and take what he wanted, and he always got what he wanted in the end.

His work in the name of his Lord and Nazarick had merely been the conduit for his monstrous impulses, a way to channel his darkest of desires. He was a demon, this was his nature and had never turned away from it. And it had brought him so much power. The fact he had a rare and unmatched gift for manipulation and cruelty did not, nor would it ever, excuse the things he'd done. Nor should it.

'What if she were to know what the ranch really was?'

He had put a spell, a massive visual and auditory illusion over the entire property, so the herd of hundreds of 'Abelion sheep' would appear as just that: sheep. But they were human; just like her. When she heard them bleat, they were actually screaming. He had her scraping the remains of fat and meat from human flesh to make low tier magic scrolls. Azazel and the other dogs were not guard and herding dogs as she thought; they were trained attack dogs, and were bred to keep his prisoners in line as they were moved from assessment, to the holding area, then to the slaughterhouse. Should a human try to escape, they had their throat torn out and were processed immediately. And Azazel, Lillith's favorite dog, was his most efficient killer. The ranch was not a farm as she had believed. It was a processing plant for human beings, and he had put a spell over it so she would aid him in skinning people of her own race.

'She can never know. She would never forgive me.'

He had never cared to think he might have try to justify his actions to anyone at any point in time. Not until now. Lillith had only glimpsed a sliver, a mere fraction of the cruelty he was capable of; and there was no hiding it not only bothered, but traumatized her. She saw him violently torture a man, and he even forced her into helping deceive the prisoner so he could extract the desired information from the man. She obeyed her master, but afterwards, once it was over, she was...quiet. A little piece of her had broken. She did not ask him to change, though. Perhaps because she knew it would be pointless, or because she was afraid of how he would react, or maybe because she understood that this was simply the nature of the beast.

She accepted him for what he was, as he was, and loved him anyways.

Proceeding with any kind of relationship other than Dominant/Submissive with Lillith would be the worst thing he could do to her.

'Shit. This is far more complicated than it should be.'

There were so many reasons why it was wrong for him to want her as more than a slave, to want to disassemble and consume every part of her, down to the last shred of her soul until she would never be separated from him.

It wouldn't even be that difficult. He was already starting them down that path... and he was _so good_at demolition. He'd been built for it, trained for it, and physically and mentally weaponized to be one thing: A deadly, destructive monster. Ulbert molded him flawlessly for his function.

And Lillith, despite her life in the brothel and loving a demon like him, compared to the monster that owned her, was an angel; as pure and innocent as a newborn lamb.

He knew, deep down, his true nature would inevitably smash her into pieces. He had already scarred her body and desecrated her mind. And even if he would willingly crawl through the jagged shards, and in being cut a thousand times feel a sense of penance, he knew it wasn't right.

Good could never love evil, no matter how evil might crave it.

But right or wrong, it did not matter. She was his to do with as he pleased, and true to his nature, was far too selfish to put her first when it came to his demonic desires.

For now though, he would have to push it all into the back of his mind, because he felt another change rapidly overcoming his body and mind. One that would demand his, hers, and Malphas's immediate attention.

Demiurge's skin felt too tight.

There's a restlessness beneath, a rushing of his blood that makes his heart pound and her insides flood with warmth.

He felt a growing, heated stir in his loins, like molten lava pouring into the base of his spine and member. It was distantly familiar, primal, and overwhelming beyond reason. It had been taking hold of him over the past 3 days, but now was when his body fully caught up with the change. The Arch Devil hardened at an alarming rate, and oh, the sweet, deep throb that came with it...he slowly arched against the bed, feeling his sac draw up. Demiurge carefully grasped his member, taking care to mind his claws and slowly stroked upward, his lower lip catching between his teeth.

The demon's hips rolled into his palm, running his other hand over his chest, and he gasped as he grazed a tender nipple; normally they weren't anywhere near this sensitive. It sent pleasurable pulses to his lower belly, his cock twitching in response and leaking over his hand. His slit was dripping a considerable amount of precum.

Demiurge moaned, pulling downwards at his member, feeling it swell more in his grip while he pumped himself more firmly. His knees hitched upward, feet bracing to push himself into an arch while his hand slid wetly over his shaft. His fingers pinched lightly at his nipple, now so tender that the barest touch made him throb and shudder.

Fuck, he felt good. His breath grew coarser with each tug, pinch and arch, his body running scalding hot and shivery.

Demiurge bit his lip harshly, swiping his palm up to his swollen and sensitive head, letting pre-ejaculate smear with every brush over his cock, slicking his hand to stroke at his length and firmly tugging until he was on the edge.

His crystalline eyes rolled back into his head, and he felt the base of his cock swelling outward as his knot grew. With his other hand he continued to brush over his chest.

When he closed his eyes-- it is her voice in his ear. He can't seem to block out the breathy little sighs she'd made, his name leaving her lips in a desperate cry that pleaded for more. More of what he could give her.

And he gave her so much.

She's such a tiny thing. So small and fragile but remarkably resilient. He did not doubt she could take his knot. No, she would. And she would love it as he locked them together and filled her with all that he had, just as much as she enjoyed tying with his Doberman.

If he wasn't already about to come, he would have woken Lillith up by rudely shoving his cock in her mouth to finish.

He shuddered as his pelvis flexed with every rhythmic pull of his hands, and the muscles in his belly spasmed, warning him of the orgasm about to rush out of him. Instinct demanded he find someone to tie with before it was too late, but now was not the time to try to explain to her that this week would be about nothing but serving his animalistic urges and violent fucking.

_'As if that wasn't her main purpose already.'_He chuckled to himself, his tongue curling over his fang as he imagined how sinfully fun this was going to be; how her tight little passage would clench over his knot as he tied with her, trapping him inside as he filled her to the brim.

He used his other hand to gently squeeze his inflated knot, and he groaned low in his chest as every muscle in his body clenched, and then slowly released in an agonizing, powerfully throbbing euphoria.

Demiurge exploded all over his chest and hand, and his breath hissed out of him, and he barely realized he was murmuring _'Yes, yes...Fuck, yes'_at the pulsing pleasure. He was coming so hard he saw white blazing behind his eyes, soft growls leaving his mouth while his member twitched in his grasp.

He panted hard, still spurting from his prolonged release. He slowly massaged the bulge, teasing his nipple as he continued to come all over himself until his knot gradually deflated.

There is so much of it, it flooded out of him to make a mess of his bed coverings in a way that he knows will have him stripping his bed when he is able to leave it again.

He licked his lips, catching some of his hot, milky release on his tongue, a pleased rumble leaving his chest. After 15 minutes, it was finally over and he was absolutely drenched in his own semen; he decided (once he could feel his legs again) he best take a shower before it all rolled off of him and made an even bigger mess on the bed.

He vowed the next time he came, it would be inside Malphas or Lillith.

It was time for his Rut.


The next evening, Lillith gingerly carried two trays of flame-seared rib-eye into the dining area of Demiurge's quarters. She couldn't be happier to feel safe in her own home once more. She no longer had to fear Shalltear or any of the other Guardians; Malphas and Demiurge effectively made an example out of Albedo, ensuring her safety and freedom to move about the Tomb freely. No one within Nazarick would dare lay a hand on her ever again.

She brought her Masters their dinner, and she sat down to eat with them, and watched as Malphas inhaled the scent of the savory steaks and licked his chops. As Demiurge entered the room to join them, Malphas's demeanor changed; he sniffed the air again, and seemed to detect another scent...she could see that it bothered him; a mask slipped into place over his features in effort to hide the entirety of his reaction.

He glanced to his brother, and Demiurge met his sapphire gaze. A silent communication ensued. Malphas raised a brow inquisitively, and his brother replied with a short nod. He either smelled it too, knew what it was, or both. The elder demon ran a hand through his hair in a gesture that indicated mild distress.

"May I speak to you privately for a moment, pet?" Malphas asked, and quickly ushered her outside of Demiurge's quarters.

Malphas looked a little worried. It seemed he could smell something unsettling in the air, and Lillith could see it made him rather uneasy.

"I don't want to alarm you, but your Master is about to go through his second...cycle." Malphas murmured quietly once they were behind closed doors, as though he didn't want his brother to hear.

"What-what does that mean?" Lillith asked.

"Incubi go through a breeding cycle every two years, what we call a Rut. It means as not only an Arch Devil, but an Alpha Arch Devil, he will become very aggressive; more so than usual." Malphas explained. "He will be extremely dominating and sexually hostile for the next week."

Lillith was quiet for a moment, as though waiting for him to say something else; when he didn't, she just giggled. That was nothing unusual for the demon. Malphas playfully rolled his eyes, knowing what she meant. Demiurge was always sexually driven and domineering, as such is the nature of the Incubus.

"Trust me, he will be taking it to a whole new level and it will take you by surprise. I was there for his first, and shit, I_couldn't even keep up with him, Dominant or not. He initially scared the Hell out of me with how aggressive he was. You can try to lock yourself away, but he will inevitably find a way to get to you, and nothing will stand in his way. He will be relentless, _insatiable, worse than he is now. He's going to mate with you, but it will be different this time as his 'equipment' will be...changing temporarily. He...well, you know how it was with his Doberman? It will be similar, as he will be forming a new component. He's going to...tie with you."

Lillith's heart flipped into her throat. She remembered what it was like with Azazel; how odd, but fascinating it was. But Azazel is a dog. Demiurge, frankly, is bigger and a Hell of a lot more forceful.

"What...what do I do?" She asked. "Will he-will it hurt?"

Malphas sighed.

"Honestly, I can only recommend to try to hang in there until it's over. I don't believe you will be in any mortal danger or that he'll intentionally hurt you; probably just scare the Hell out of you and then fuck you senseless. It's his second cycle; the first was rather rough. I eased him through it and got him off as often as I could, but it only took the edge off; he really needs a female to satiate his hunger to breed, as it will shorten his Rut. He'll be seeking what he deems as an Omega, a submissive female with a pleasing scent that also compliments his Alpha attributes to tie with, which describes you perfectly. Genetically, you are incompatible, so there's no need to fear getting pregnant."

"Oh..ok." Lillith was still somewhat stunned, and at a loss for words at such news.

"I just wanted to advise you ahead of time before it hits him fully, so you will at least have an idea of what to expect. You are most likely safe for tonight, but tomorrow...be prepared. I'll try to keep the worst of it under control, exhaust him when I can, but unfortunately I cannot be there 24/7. Because it will be a week before the height of it wears off."

"...I should be alright." She said, trying to sound sure of herself.

"I'll have him sleep in my quarters tonight, just in case. But I would say he has about 12 hours before he is completely overtaken by his primal instincts. Satan help you if you get aroused around him; he'll scent it from a mile away and chase you down like a mad dog." Malphas assured her.

Lillith was anxious...but excited. She liked the idea of him being so riled.

This would be a new experience. Azazel's knot was certainly interesting, but if Demiurge had that component...she shuddered in delight.

"Easy, pet. Remember, if I can smell it, so can he. I can control myself, but he won't." Malphas warned with a sly grin.

"Sorry...it's...thrilling." She said and bit her lip. "Will it happen to you too?"

"Possibly. We are both Alphas, so our bodies are designed to compete physically with one another for the right to breed. The first time the pheromones of his Rut triggered my own to begin, and that is quite likely to happen now that there is a female in the vicinity. I will try to suppress mine, though. The last thing you need is two Alphas fighting to knot you."

Lillith swallowed as the image of them both spit roasting her flashed through her mind.

Malphas then smelled her arousal drastically spike.

"Damn it. I shouldn't have said that." He scolded himself and chuckled. "Keep it together, little one. I'll need a chance to wear him out a little before he unleashes himself on you."

Malphas made it seem like he would be so...wild. Dangerous. This might be fun. Terrifying, but fun.

They returned to the table and seated themselves, and Lillith cast a brief and nervous glance at her master. Demiurge's gaze locked with hers, and it was smoldering enough to start a wildfire. He said nothing, but licked his lips and flashed her a possessive, predatory grin, making her stomach flutter.

The message was clear: "I'm going to fuck you so hard. "

She knew she was in trouble.

Malphas noticed the exchange, and Lillith's nervous apprehension. Demiurge's tail swung from side to side in unrestrained excitement, and he could hear his brother's cock flex in his pants as he got hard. He narrowed his eyes at the younger demon.

"Behave yourself, brother." He hissed in admonition.

Demiurge then turned his heated gaze onto Malphas, and he flashed him an insidious smile that was all fangs that said:

'I'll fuck you too, Malphas.' It was enough to send a shiver up his spine.


After dinner, Demiurge and Malphas retired to the elder demon's quarters.

Malphas poured them each a glass of red wine, and they both downed the first like it was nothing.

"Why didn't you tell me sooner your Rut had started?" Malphas asked as he unbuttoned his suit jacket.

"Honestly, I didn't realize it until last night. My..._emotions_had been all over the place lately, and in light of all that had happened, I thought it was simply a result of recent events. Until my knot began developing last night, I couldn't be sure." Demiurge admitted as he plopped down on the couch.

'Shit, his knot already formed? He's further along than I thought.'

Malphas poured them another.

"I gave Lillith an idea of what to expect. She knows you will be a little more...aggressive, but she should be able to handle it, based on what I heard through the walls last night." Malphas smirked as he recalled his brother's bestial grunts and growls and his pet sounding as though she were being mauled by a bear. "Sounded like you both had a Hell of a lot of fun."

They both laughed heartily, knowing fully well if Nazarick was not separated by multiple floors, every denizen of the Tomb would have heard their racket.

"Indeed. She will be fine." Demiurge chuckled, and pulled a pack of cigarettes out of his breast pocket and put one between his lips. "I can't fucking wait to bury my knot in her later_..._"

Malphas smelled his arousal blooming, and felt the hackles of his hair rise in response.

_'Damn it. Not now.'_He scolded his instincts. One of them needed to keep a level head; if not for all of Nazarick's sake, at least for Lillith's. One Arch Devil in Rut she could probably handle, but two? She would never walk right again.

He choked back a growl, his own Alpha competitiveness threatening to claw its way to the surface.

"Fuck, Demiurge. I'm trying to hold it back, but you're going to make it impossible if you say things like that." He warned as he ran a hand through his mane, trying to flatten it back down.

Demiurge knew exactly what he was doing, but didn't care. His instincts commanded him to antagonize the other Alpha; throw his weight around as he was slipping further by the second. Malphas thought he had more time before it overtook him, but he was wrong.

"Mmmm...just imagine us both tying her at once. How she would scream for us as we fill her up, her tight little body milking our knots..._fuck,_that makes me hard." Demiurge teased mercilessly, lewdly smoothing one hand over his crotch with a obscene moan, while he lit the cigarette with the other, taking a long drag. "Would you prefer heads or tails, brother?"

Malphas growled, his eyes narrowing and glinting dangerously. "You're playing with fire." He admonished him, his tail flicking in agitation.

"And I'm hoping to get burned." Demiurge hissed a ballsy reply, flashing his fangs at him in a conniving grin. Malphas watched as his canines elongated before his eyes.

Demiurge was in full Alpha mode now. His veins were being flooded by more and more testosterone by the minute. He felt God-like, as if he could bend his stronger six foot six brother over the couch and fuck him just as easily as he could Lillith. All he had on his mind now was domination. His body was overriding his usually logical and calculating mind, and it demanded he find a partner to tie with. NOW. Whether it be Lillith, Malphas, or both.

And Malphas could smell it; his testosterone, his arousal, his musk, all of it as it invaded his senses. And much to his displeasure, his own body was demanding he also fall into Rut, and compete with the other Alpha for the female he wanted to breed. The sight of his brother's fangs growing for the purpose of a deep mating bite and injecting bonding venom flared his Dominance.

'Fuck.'

The older demon growled again and crushed the glass in his hand before he realized he was still holding it.

"Calm yourself, Malphas. I'm just fucking with you." Demiurge laughed, not intimidated in the least and then took another puff.

Malphas's lip curled in an irritated snarl and shook his hand out, flinging shards of glass and blood and droplets of wine onto the floor.

"I forgot how much of a dick you can be during Rut." Malphas rolled his eyes and sighed in exasperation...but underneath his skin was the creeping urge to submit to his brother, who now projected the overwhelming aura of a much larger, more confident Alpha. So as an after note, Malphas hissed "Don't make me kick your ass again."

He hadn't intended to be so blunt, but there is something about his attitude that put him on edge. His skin felt too tight, an untouchable itch just underneath that prickled up his arms and over his throat. He blew out a frustrated breath, the pair of them just staring each other down as that same odd prickle of something trickled down his spine.

Demiurge held up his hands in mock surrender, as if to say 'take it easy', and exhaled a large cloud of smoke. Malphas huffed, assuming he got his point across with the front.

The older Devil got up off the couch to grab a healing potion out of the cabinet. He didn't feel like having to pick fragments of glass out of his hand. He was mostly pissed about his glove that was now cut in several places. He had really liked that pair. He snatched up the container of ruby liquid and popped the cork out before tilting his head back and swallowing it.

Then he heard the barely detectable sound of muscles coiling.

Malphas realized his mistake too late. He had not only taken his eyes off of, but turned his back on his brother, which he should never, ever do during Rut.

Before he could swivel around, Demiurge leapt onto his back, wrapping his arms around his chest and successfully immobilizing the larger demon, his feet bracing against the counter before he kicked outwards to send them tumbling back and onto the floor. They landed hard enough to knock the wind out of both of them, and they struggled as though their lives depended on it, gasping for breath.

Malphas snarled and Demiurge hissed as they scrambled for the dominant position, and now it was on. Malphas grappled the smaller demon and tried to push him downward and under him, but Rut had also given the younger Devil a healthy dose of adrenaline. Demiurge managed to wriggle out of his grasp and now with his heavy, armored and spiked tail swinging dangerously, Malphas played it smart and backed off of him, leaping to his feet at the same time as his brother.

"SUBMIT!" Demiurge roared, a deep and enraged bellow, and it actually rattled Malphas to his core. Had the command been aimed at anyone else, it would have turned them into a whimpering puddle of fear and resulted in immediate compliance.

"Get a hold of yourself, Demiurge!" Malphas snarled. It wasn't supposed to come out so harshly, but meant to be a firm reminder that this was his Rut making him act so wildly. Instead his tone inevitably made it sound as though Demiurge was being irrational, which just pissed him off more.

"Oh, no...you aren't getting away." Demiurge hissed menacingly. His lips curled in a predatory way, and Malphas actually felt a coldness in his spine that only comes from a kind of fear from something unknown. As the six-foot six Alpha male he was, it was something he'd never in his life experienced.

Demiurge then flung himself at Malphas head on, once more trying to knock him off balance with his full weight. Again it hurled them backwards, this time landing them over the couch. They fell onto the furniture in a tangled heap, Malphas stumbling as he tried to remain on his feet yet still ended up on his back and splayed, but he was grateful not to be face-down.

Malphas snarled as Demiurge pinned his wrists to the back of the couch at either side of his head before he had a chance to stand or shake him off of him, dispensing his weight over his thighs so that he is little more than prey. Hardly more than helpless. Demiurge's chest was heaving with both unhinged rage and desire.

Malphas bared his fangs and growled in defiance, and he shifted his hips in another attempt to scramble away, and he can feel him now -- hard and straining against his thigh. Even his scent is different. Now that he's allowing himself to really breath it in. It's sharper. More potent, now laced with what smells like scorched caramel and cinnamon.

It makes his limbs tremble a little.

Then Demiurge kissed him, stopping him in his tracks, as it was a full-on invasion of his senses. His lips angled over Malphas's aggressively, and he pushed his tongue into his mouth in an obvious simulation of sex. Of_taking_ him.

For a moment, Malphas had a brief moment of clarity and realized he was going to no doubt attempt to tie with him. While he could (slowly) take Demiurge's member, his knot was a different story. In a panic, he pressed up with everything he had -- but Demiurge slammed back into him to keep him where he was. Demiurge bit at his lower lip -- then released one wrist to tug at his long hair until there was a dull pain. He kissed him with more ferocity, and then sucked on his tongue.

Demiurge momentarily broke the kiss to mutter "I'd rather fuck than fight, brother...wouldn't you?"

Malphas finds that he is utterly helpless against these newfound urges to bend to his voice. To break under his will. Everything inside Malphas, everything that made him the perfect, all-powerful Alpha he was telling him to fight. To push back. To flip the situation, remind his Submissive, his Omega of his place, but there was something deeper. Something that begged him not to. It's smaller, weaker-- but still so loud he can hear it rattling through his bones.

Demiurge needs this, needs Malphas to let him have this.

And would that really be so terrible? He tasted like wine, wildfire and dark, unbridled desire. Demiurge's Alpha was quickly subduing Malphas's own, and goading him into handing the reins over to the microscopic shred of submissive within himself; and damn it all, he found himself wanting to allow this, to obey and please him.

'Fuck.'

Why the Hell did he have to be so persuasive and sexy?

Demiurge groaned against him as he swept his velvety tongue over his, and Malphas stopped straining. That sound seemed to reverberate through him, and he felt a slight tremor run through his massive, rock hard body right back into his.

The younger demon's arms came down around his to slide beneath and cup his ass, pressing Malphas into him with explicit intent. He felt the heated, hard column of his member stabbing more insistently into his inner thigh, and it made him dizzy.

Demiurge didn't kiss like he was pissed at him. He kissed like an Arch Devil who wanted to devour him.

Malphas felt warm, clenching drags of raw desire claw through his belly and another surge of need in his groin when Demiurge ground his length against him. The Rutting Devil moaned raggedly into his mouth and the sound shot a spike of pleasure straight to his core.

'Shit, he has me right where he wants me.'

Demiurge's hands left his rear to move to his shirt, unbuttoning the top few buttons while planting hot, wet kisses on his neck and face. He lifted him up and braced him against the couch, continuously grinding his throbbing erection into his abdomen.

"Demiurge," Malphas moaned, his hands gripping his collar, just as eager to get his clothes off too, his claws digging into the muscles of his chest.

"_Mmm..._you want that?" Demiurge asked hoarsely, gently biting his neck at the pulse point, then licking the spot.

"Yes," He moaned again, and he felt his body shiver against his. "Please."

"This is the only knot you will ever take," He hissed darkly, staring into Malphas's heavy-lidded eyes as he panted. He rolled his hips against him again, knowing he could feel every inch of his heated desire pressed against him through their clothes. "I'm the only Alpha that will ever satisfy you, the only cock you will ever want."

"Yes!" Malphas surrendered as he could feel his brother's heartbeat through his cock, and he desperately wanted to feel it pulsing inside him.

Demiurge knew this and smirked, and withdrew to stand in front of him, pulling his zipper down to free himself.

"Then get me good and wet," He demanded. "...Omega."

And the taut thread holding the last of Malphas's control snapped cleanly in two. His ears lowered and flattened submissively, the many rings adorning them jingling. He leaned forward and swept his hands up and down his brother's thighs, over the muscled delineations of his hips under his dress shirt and around to his backside as he licked his way from the base to the ridged head of his cock .

Demiurge moaned throatily. He almost sounded like he was in pain as he hardened even more like marble, the gleaming head flushing purple. Malphas wanted to hear that sound again, so he wrapped his lips around the swollen tip of him, gripping the base with one hand. He was so thick his fingers barely met as he gripped him.

'Holy hell. This is going to hurt.'

One of Demiurge's hands was braced on the top of the couch so he was inclined forward just a bit. Malphas felt his other hand tentatively rest on the side of his head.

"Mmmm...very good, brother." Demiurge praised him.

Malphas twirled his tongue around the head of his cock and slid his hand up and down the shaft. Demiurge let a gasp escape and the elder Devil showed his approval by moaning in response. Demiurge rumbled back and gripped his dark mane in his hand.

Malphas pressed him in further, guiding his tongue along the thick ventral vein ridging his shaft and gave him a long, hard suck as he gazed up at him. He moaned again, more aggressively, still working his fist up and down the base, which he now felt was swelling outward as Demiurge's knot began to form. Instinctively his hips began to buck into his warm, moist cavern.

A pleased growl left the younger demon's chest when he moved lower to fondle his brother's testicles and then lave at the growing bulge.

"F-fuck, Malphas..." He groaned as his brother teased his knot. "Don't you dare make me come yet."

Demiurge's hand fisted his hair hard as Malphas suckled at his knot, pulling shuddering cry tearing from his throat. Malphas drew back up--pulling almost completely off to mouth at his gleaming head, flicking his tongue against the slit there and lapping up the dewy beads of precum that escaped him.

"Take them off." Demiurge ordered him, finally satisfied he was slick enough for what he was about to do.

Malphas obeyed, pulling away from him completely and to unfasten his belt and pull his pants off, and was still unbuttoning his shirt when Demiurge had already completely torn his clothes off and was already lifting his thighs and dragging his leaking tip over his entrance in preparation to force his way inside.

In one sudden, ruthlessly hard push, Demiurge buried himself in him, all the way to the edge of his knot, reveling in his brother's strangled scream. Malphas's hands slammed on his shoulders with a ragged and broken cry.

"_ Fuck , Demiurge! _ You...you couldn't...give me minute to adjust?!" Malphas gasped and hissed. His brother was insanely thick, and it burned like molten iron impaling him.

The younger demon was not so much long as he was wide. At about seven inches, his length was a little more than average, but his girth was truly something to behold.

Demiurge growled incoherently, almost beyond words at this point. Malphas thought he could make out "Sorry," and, "so tight", and "feels so good".

Malphas whimpered in pain and clung to him as if he were the only thing anchoring him to the earth, and Demiurge felt the god-like sensation of Dominant power mixed with a terrifying vulnerability, and shifted to plunge again.

Malphas snarled, the growl collapsing into a agonized whine. Demiurge paused, now hearing and heeding the heart-wrenching sounds of his brother's pain cutting through the fog of desire. He waited a few moments before he leaned down to kiss Malphas's gasping and open mouth, and then drug himself out of him and then pushed his more-than-impressive girth back in, slower this time, as he plundered his mouth with his tongue.

Demiurge pulled his mouth from his and slid into him again, eliciting another little growl of pain from him. He brought his hands up to open Malphas's shirt and gently smoothed his hands over his pectorals, being attentive to the rosy nubs, trying to soothe what he knew had to hurt like Hell.

Malphas hissed through his teeth as a sharp flare of pleasure rippled from the touch.

"I'm sorry...you're right...that was so selfish of me." Demiurge apologized, his voice soft and his regret genuine. He was so consumed by the lust and mind-numbing sexual drive of Rut he didn't consider his brother's, his Omega's needs at all.

'Alpha nurtures, Alpha cares for, Alpha puts Omega's needs first. You failed.' His most basic instincts, his hind-brain scolded.

The smaller demon gently rolled his thumbs over the dusky peaks, and Malphas hummed appreciatively as it did at least take the edge off. Demiurge nipped his throat and lightly pinched the nubs, drawing a shallow gasp from the elder demon's lips.

"Damn right, it was...I think you sometimes forget how thick you are. Shit." Malphas agreed, and Demiurge chuckled.

Demiurge was still young, and this was only his second Rut. Malphas had four under his belt, and was more experienced, so his brother's amateur mistake was not shocking. But fucking Hell, was it painful. Malphas had never allowed Demiurge to fuck him, much less tie with him during Rut before, for this very reason. He would let him fuck his mouth, or jerk him off. And he was always especially careful to not turn his back on his brother in this state of mind.

But there was a new factor this time; a female in the vicinity, which made his hormones and pheromones rage three times as hard. So he couldn't be too angry with him as he lacked experience in maintaining a level head during his cycle.

"You're cock is bigger than mine. Eight inches of steel. How do you think _I_feel when you fuck me six ways to Sunday?" Demiurge playfully argued, and then lowered his mouth to his nipple to swirl his tongue around it, earning a low moan.

"Maybe so, but you've never had a knot inside you. Hell help you when the time comes." Malphas said with a smirk. "Mine will split you in half."

"I do not doubt it. Yours will certainly be much more to handle. But if you take mine, I'll take yours." Demiurge offered a compromise, and then hallowed his cheeks to suck, making Malphas's eyes roll back.

"Alright...get it in now before it fully expands." Malphas relented.

Demiurge kissed him again, almost apologetically before he lunged forward without hesitation, crushing the breath from Malphas's lungs with the force of the thrust.

A broken cry left the Elder demon's mouth as Demiurge's growing knot was forced inside of his passage. Malphas gasped in his mouth, his talons reflexively raking down his brother's back, cutting him open.

Demiurge groaned as he was deeply gouged by Malphas's razor-sharp claws, then gasped in ecstasy as his channel clenched around his knot. Malphas panted heavily, his walls quivering in shock

"You handled it well, brother." He whispered and then nibbled his earlobe, trying to ease the agony.

Malphas trembled and whined as he was stretched far beyond what he was used to handling. As the usual Alpha, he was so very tight, so unused.

"Shhh...it's ok. I've got you." Demiurge purred and nuzzled him sweetly. "Your Alpha is here."

"...Hurts..." Malphas whimpered. It was all he could muster; Demiurge's knot felt huge, and it still wasn't fully inflated.

"I know, Omega...it'll get better. I promise." Demiurge assured him, his tail corkscrewing around his brother's. He sucked the spot below Malphas's ear, drawing a breathy gasp from him.

Demiurge reached between them and grasped the larger demon's aching length, slowly stroking upward. This prompted a throaty groan, and then a shudder as he skillfully added a light twist over the bulbous head.

"Does this help?" Demiurge murmured huskily.

"Yes...yes, don't stop." Malphas pleaded, his deathgrip on his brother loosening just slightly. "Please, Alpha."

Hearing his older brother address him as Alpha almost put him over the edge. He can't help the lick of pleasure up his spine that is born from his Omega begging something of him. Needing him. It plucks at something primal, older than them both that lives deep inside their genetic coding.

Malphas whined, pushing up into his hand. The tension his body had held was beginning to unravel, and Demiurge could scent the blind pleasure that is tinged with deep-seated relief rolling off of him.

"Alpha, please..." He whined.

"Fuck, you're so sexy, Malphas..." Demiurge growled as he gazed down at the beautiful Arch Devil beneath him, nipping the tendons of his neck as he continued to firmly stroke him. Malphas's crystalline eyes held the chilling color palette of arctic oceans, startlingly deep and so many shades of blue. They were even more striking when complimented by the pretty pink blush highlighting his cheekbones.

And to know this magnificent and powerful creature was his, letting him take him, _own him_completely like this...it was intoxicating. Demiurge claimed his mouth again, their breath feeding into one another and Malphas bucked upward, letting him know he was ready.

Demiurge smiled against his lips, and rewarded him with a firm pump his hips, a sinuous roll, so slow it felt like punishment. Malphas let out a gasping moan, ecstasy lacing his vocal approval as Demiurge's expanding knot tugged gently across his prostate.

"Better now?" Demiurge asked.

Malphas only nodded, his eyes rolling back into his head as Demiurge slowly pulled back to push in again.

Demiurge's knot was locked inside him, but his need for him wasn't yet satisfied. He pushed against the tightness, feeling the way his knot is resistant to being separated from the warmth of his brother. With every tug, more of his own fluids flood his passage -- and there is so much precum already.

Still he works at him. He ignores the frantic little pleas and the needy gasps as he fucked Malphas through his knot's growth. It's shallow, very little give to the short thrusts, but with coaxing he's able to just pull from his body to slide back inside. He closed his eyes as the slippery stretch swallowed the thickened flesh of his knot, and Demiurge murmured with dark husk in his ear "Good. Because I'm going to fill you with everything I have.

Those words sparked a fire in the pit of Malphas's stomach, and he couldn't stop the sharp intake of breath and how the hair on the back of his neck flared.

Demiurge began to move faster, more steadily, one hand pumping his brother's shaft in time with his short strokes. Malphas clutched at him desperately as the younger demon worked his hips into his.

"D-Demiurge, fuck!" He cried out as his brother's knot pushed and pulled against his internal sweet spot.

Malphas gasped his name, his senses narrowing down to only Demiurge's hand wrapped around his member, and his length driving into him, his knot swelling thickly within. His head lolled limply as he was overtaken with rapture.

Demiurge's eyes glittered with lust and he rumbles against Malphas's neck, "You gonna pass out? Don't you fucking pass out on me, Omega..."

A weak groan is Demiurge's only assurance that Malphas is still conscious.

"We're not done, yet," Demiurge warns. Malphas senses they are in the eye of the storm.

One hand still gripped his hair, holding his head up, so he can watch his reactions - it doesn't hurt, but it tells him exactly who is in charge. His other hand left his aching cock and roamed freely over the valleys of his chest and abdomen and back as if he owned him, clearly indicating he can do whatever he wants and there will be no stopping him as he continued with his furious pounding.

Demiurge felt it building inside him--that heady pressure that coils and churns and blooms as it tingles up his length. He knows that very soon he will lose it completely, and he struggles to hold out, tangling his fingers in Malphas's hair as he fights it.

"Come for me, Malphas." Demiurge commanded.

To his relief, that was all Malphas needed; Demiurge felt his brother's talons mercilessly dig into his shoulders as he threw his head back and roared, his channel clenching around his knot tighter and tighter as he suddenly erupted in high arcs between them, crying out his brother's name as he painted his bare chest with spray after spray of his hot release.

"Hell yes, come around my knot." Demiurge growled. He plunged twice more and let go, hurling himself over the edge of oblivion with him and snarled vehemently into the crook of his neck, and then sank his fangs into his flesh in a deep mating bite. He spurted endlessly into Malphas's silken channel, his teeth clenching with pulse of pleasure.

There's nothing really like it, the feeling of being locked inside him. He thinks if he were to describe it he would mention the heat mostly--a slick warmth that envelops him wholly and makes him feel just that. Whole. He can feel the way his muscles contract inside, a flutter of his inner walls that grip and squeeze around the thickest parts of him, and his entire body shudders with how overwhelmingly perfect it is.

He was sweating hard when he gained control of his senses. He braced his hands, lifting lightly off of Malphas; something he immediately regrets because this caused a tug where they're joined that sets forth a dizzying pleasure and a gush of his cum that makes him see stars--and he winced a little now as he propped himself up to look at him. He settled with his thighs on either side of his, and wrapped his arms around his neck for stability.

The next thing Malphas was aware of was that he was leaning against the couch, with his brother straddling his lap. Demiurge's soft moans into his neck accompanied the long, involuntary pulses of his passage, squeezing and milking his throbbing knot in rapturous bursts that drew low whines from his brother's throat.

Malphas hummed appreciatively as hot semen continued to spurt inside of him, but even more pleasurable was how close this was to voluntary affection from Demiurge. Malphas rarely got to hold or hug his brother. Even if it was to maintain the tie, he enjoyed it nonetheless. He felt safe, secure,wanted in his Alpha's arms, and Demiurge shuddered as another pulse of pleasure made him clench around his knot, pulling more of his seed deep inside him.

"Fuck!" Demiurge gasped breathlessly, tensing and shaking through it, his hips making desperate little hitches, trying to press even deeper inside. "Fuck, you feel so good around my knot..."

Malphas just moaned in agreement, and smiled hazily, holding him tighter as they rode it out together.

"How long do your ties usually last?" Malphas murmured a few minutes later, when the pulses finally started to slow down.

"Between fifteen to thirty minutes." Demiurge replied.

"I'll certainly enjoy every moment of it." Malphas said contentedly as he buried his nose in his brother's hair. He smelled so good. Like dark spice, wildfire, and home. "This...this is nice."

Demiurge would normally grumble and push him away, but this time...no, he wouldn't do that. Because he agreed. Maybe it was just his Rut, or the flood of endorphins coursing through his veins, but couldn't argue with him this time, because this was nice.

"You like being knotted?" Demiurge asked.

"I believe I do. It hurt like Hell at first, but now...it's quite pleasurable." Malphas admitted. "But I must insist you ease me into it next time."

They both laughed, and Demiurge rested his forehead against his.

"Sorry, brother. I was admittedly overtaken by the drive to breed." Demiurge confessed. "I wasn't trying to hurt you."

"I know. Control over it comes with experience. It will get easier. But do try to go easy on our pet. She's more fragile than I." Malphas advised.

"I will certainly try. But you know as well as I do she likes it rough." Demiurge smirked. "She's tougher than she looks."

"Indeed. But let's not break our little one." Malphas insisted. "I'd like my chance to knot her as well."

Demiurge nodded, letting it drop and nuzzled his brother's neck once more.

"I'm glad you're with me again...living here in Nazarick." The younger demon murmured. "I've missed you, Malphas."

The elder demon gazed down at him, wide-eyed with genuine surprise. Demiurge normally did not say things like that. Even if he knew it to be true through his actions, Demiurge never uttered anything that might make him seem vulnerable or needy.

"It was hard without you for those years...when Ulbert assigned you to the stables across the map. I was so lonely...I tried to fill the void. As you know, the first human I purchased was a nightmare. Then there was our pet. She helped, but...it just wasn't quite the same, or enough. She was only half of the missing piece. But made from that same thread that binds me to you. But this...I had missed this. Missed us." He continued, and drew a shaky breath as he released again within him. "You complete me, Malphas."

Malphas licked his cheek. How he had needed to hear those words, because he felt the same way.

"I had missed you too, brother. The dream trysts were fun, but paled in comparison to this; to feeling your warmth, your heartbeat, your teeth on my flesh." He cupped his face gently, his sapphire eyes meeting his. "I'll never leave again. I promise."

Demiurge purred and leaned into his touch, perfectly content for the first time in years.
