Chapter Text
Alastor always knew he was twisted.
From his human days of hunting down psychopaths and murders so he could feast on their entrails to his present days where he did the same.
Carving up a body never repulsed him. He would relish in the bits of color that a corpse would produce, the yellows of bile, the crimson blood that he would eagerly drink down, and the white of bones once a corpse was picked clean. The screams of each victim became as sweet as the music that played through the radio. A wonderful symphony that always sent a thrill of excitement through his body. The knowledge that these terrible souls had been punished brought him comfort.
But it wasn’t enough.
Rampages didn’t quench his thirst anymore. No matter how many guilty souls he devoured, he still felt an itch under his skin, parchment in his throat. He was never satisfied.
Until Him.
When Charlie’s absent father first came to the hotel, Alastor couldn’t believe his luck. The smell of the man alone was enough to set him on edge. It was hard to describe other than it just divine, pure, untainted. Like this is what he had been waiting for.
They had done their little song and dance with each other. Sure he had lost his cool and cursed at the short king, but he remembered how those yellow and red eyes narrowed at his words. Almost inviting him to try, if he dared.
And he dared.
That’s when his obsession with the king began. Every day was filled of thoughts of Lucifer. What his flesh tasted like, his blood, his tears. Everything.
When the thoughts came to him at night, he found himself for the first time in ages aching for someone to touch him. More often than naught, he would snake a hand down his pants and bring himself so close to the edge he could taste it before stopping short of his orgasm. He would deny himself the pleasure of release until he had Lucifer whining and begging for his touch and his blood on his tongue.
This hunt would be fun.
At first, he started off slow, a smart hunter knows better than to advance too swiftly around prey. At first, once the excitement from the cancelled extermination died down, he would seek the king out and ask for his help on a project or activity. Nothing he couldn’t usually do on his own, but something just big enough that needing two people to assist with it would be believable.
He would drag the king off wherever it was they needed to go and as they preformed the task, he would ask him an occasional question. At first, they were your usual mundane ones. How are you doing? Charlie sure is a sweet kid, yeah? And so on.
However, once Lucifer became somewhat comfortable around Alastor, he grew bolder. Asking about his likes and dislikes, how he prefer caramel apples as a snack and how he used his ducks as an outlet for his depression.
It was a typical day when Alastor decided that he would strike.
He had drug the king off to one of the more remote room in the hotel. A door had ‘mysteriously’ fallen off its hinges. Sure, Alastor could’ve used his tentacles to hold it in place while he screwed it back in, but Lucifer didn’t have to know that.
He hummed softly to himself as he screwed the middle hinge into place. Due to his height, he had to duck down just a little bit while Lucifer had his hands firmly planted on the door itself. Just as he was about to bait the hook, his little fish seemed to jump out of the water himself.
“Hey, Al? Mind if I ask you something a little personal?”
He turned his head to the king and widened his ever present smile, “Absolutely, Sire! I’ll be happy to answer whatever you have prattling around that little head of yours.”
Lucifer scoffed at the ‘little’ part before taking a deep breath and asking, “Why are you always asking me to go off and do stuff with you? Not that I’m complaining! Truth be told I’ve actually started to enjoy your…specific brand of company...”
He trailed off and looked down to the ground. Alastor chuckled softly, causing Lucifer to face him once more, “What can I say? I had the desire for companionship one day and who better to stimulate the mind than someone like yourself? I’m aware we got off on the wrong foot when you first arrived here, so I wanted to mend the fence so to speak. Now that I think about it, I believe I agree that I’ve began to even enjoy your company as well, Sire.”
A hint of a blush decorated the kings face as he swallowed hard. Alastor had to stop himself from purring at the sight of Lucifer fidgeting in place.
He finished screwing the hinge and stood back up to his full height. He made quite the show of stretching out his achy back. Out of the corner of his eye, he noticed Lucifer was watching him hungrily as he stretched the stiff muscles out.
Perfect.
He straighten completely up and looked down at Lucifer. The shorter man was gently pushing the door back and forth, making sure it was secure. Lucifer glanced up at him and softly murmured out. “I think you’ve pretty much fixed it. Sorry I wasn’t more helpful.”
Alastor clicked his tongue and softly shook his head, he almost couldn’t believe how easy this was for him. He reached down and firmly clasped the kings shoulder, not missing the shiver it produced, and bent down until they were eye level. Their lips were merely inches apart as Alastor purred out, “Do not apologize, Sire. You did me a great service. Not only did you support the door, but you provided me with some excellent company. Perhaps I should be apologizing to you for wasting your time, hmm?”
Lucifer’s eyes grew wide and he sputtered out, “N-no! That’s not what I meant at all! Just it was a simple task that I didn’t do much with, ha ha! No, you didn’t waste my time at all. It was enjoyable…would it be weird if I said I still wanted to hang around some more?”
Too easy.
Alastor leaned forward slightly, their lips were almost touching, “What do you propose we do next, your majesty?”
A little gasp escaped Lucifer’s lips as Alastor slid his hand down the kings arm. The Overlord stopped right by Lucifer’s thin waist and pulled his body slightly closer to his own, the angle he was bent at made it difficult to press up against the king, but the effect was still the same. Lucifer shivered hard, “Alastor…are you…?”
“Only if you desire so, my liege.”
No sooner than the words escaped his lips, Lucifer pulled him in for a deep kiss. He moaned softly against the soft lips and placed a firm hand at the back of his head to keep him in place. Lucifer gasped as Alastor ran his tongue across the plump bottom lip slotted between his own before nipping at it gently.
Lucifer moaned and allowed the Overlord access to his mouth. Alastor wasted no time driving the long appendage in, wrapping it around Lucifer’s own and sucking gently. He released the firm grip in Lucifer’s hair and traded it so both hands could grab the shorter demon hips and lift him up off the ground.
The king gasped at the sudden change of position, but recovered quickly by wrapping his slim legs around Alastor’s waist. Small hands grabbed at his back at the kiss grew more intense. Their sharp teeth nicked the others lips causing golden and crimson blood to spill between the two of them.
When the first drop hit Alastor’s tongue, he almost came undone on the spot.
The smell of Lucifer didn’t compare with the taste of his blood. Perfectly metallic with a subtle hint of sweetness. It was light on his tongue and the sensation it gave made him think of floating on a cloud.
He wanted more.
Every so slightly, he pulled away from Lucifer’s tempting lips to lap up the blood that spilt between then. Lucifer whined softly and ground his hips against Alastor’s stomach, “Alastor, can we please..?”
The Overlord caught Lucifer’s eye and groaned softly. The fallen angel was already looking a mess. His perfect blond hair was disheveled and his face was almost more gold than white due to his blush. His pupils almost took over the entirely of his red iris and he was panting hard.
He stooped his head down to lick a long stripe up the king neck, who whimpered in turn, “Use your words, my king. What would you like me to do?”
Lucifer cried out as Alastor bit into his neck, not hard enough to draw blood, but enough that the Overlord felt his cock twitch against his stomach, “Please, Alastor. Fuck me.”
“Well I did offer to once didn’t I?”
Before Lucifer could comprehend his words, he used one of his claws to cut the kings pristine white pants. He made sure to leave a large opening in the back for himself and gingerly cut around the front to allow Lucifer’s member to spring free. He growled softly when he noticed there was a lack of underwear to cut through.
‘I wonder how prepared he came.’ Alastor thought to himself. He dulled his claw and used it to circle Lucifer’s entrance, finding it already pliant and slick beneath his touch.
“Naughty king, did you already prepare yourself? Did you plan on this happening or were you that hopeful?” Alastor growled the words out and raised up to look at Lucifer. The smaller demon whined and wiggled his hips against the finger, trying to make it go inside, “If I say yes, will this move this further along?”
He was desperate. So desperate it was beautiful.
Alastor moved forward until Lucifer’s back was against the door frame, one hand held the king up while the other one went down to his zipper. He wasted no time in undoing his pants and allowing his thick cock to fly out. Lucifer glanced in between their bodies and moaned when he saw the size of it, “That’s not going to fit, Alastor.”
The Overlord gave him a wicked smile and placed a chaste kiss on his lips, “Have some faith, Sire. Haven’t we all agreed that a little hard work can produce some heavenly results?”
Lucifer whimpered and eagerly nodded his head, “Then what are you waiting for?”
With a snarl, Alastor placed both hands back on Lucifer’s hips and held him just above his erection. He placed the blackened tip against the stretched hole, pressing in just enough to make Lucifer squirm, “Say my name, Sire.”
Lucifer groaned softly, “Alastor, please. I want you inside of me.”
“Good boy.”
Without another word, Alastor slid in to the hilt. Lucifer quickly slapped a hand over his mouth to stop a scream from escaping. They may have been in a more remote area, but someone could wonder by and find them at any moment.
Alastor growled deeply as Lucifer’s walls squeezed around him. The king was so hot, tight, and wet on the inside, the sensation alone almost made him dizzy. It had been decades since he last entered another demon, but he didn’t remember any of them ever felt this good.
He wasted no time in thrusting his hips forward, the motion cause Lucifer’s back to dig into the door frame, but if the king cared he didn’t voice it. All Alastor heard was yet another sweet moan and he pushed even deeper inside the hot canal. He set a firm but slow pace, deeply fucking into Lucifer and moaning along with every time his tight hole clenched down on him.
But he needed more.
He leaned down to kiss Lucifer hard as he gradually picked up his pace. What was once slow and deep thrusts became hard and fast ones. They both moaned against each other’s lips as the slick sound of skin slapping on skin rang through the air.
Lucifer had taken his arms and thrown them around Alastor’s neck. He pulled the Overlord close to his own, “Fuck! Alastor, you feel so good inside of me. Ah! Right there!”
He moaned as Lucifer started to come undone beneath him. With a deep growl, he leaned forward and eagerly sunk his teeth into the pale column presented before him. Instantly, mouthfuls of heavenly blood filled his mouth that he swallowed rapidly. He moaned loudly at the taste of it; Lucifer was almost crying from the sensation of being filled and from Alastor’s bite. He thrashed hard against the Overlord, “Ah! Sl-Slow down, too much bl-ah-ood can be bad for you! Please, Al!”
Alastor snarled against the side of Lucifer’s neck and slammed into him hard, causing the king to cry out and for his teeth to slip in deeper. He felt like he was swimming, everything had almost a shimmer to it when he opened his eyes and he felt weightless.
Lucifer roughly grabbed him by the back of the head and yanked him off. He started to growl but stopped when he saw that Lucifer’s horns had grown out and his eyes were starting to turn red, “Stop.”
It wasn’t a request but a command. One that Alastor had no choice but to follow less he want to end his afterlife. He almost whined as he watched the honeyed blood slowly flow out of the wound. He licked his lips but fought the urge to dive in again, he could feel cracks in his sanity slowly start to form at the lost. He wanted more, he hadn’t felt this satisfied in years.
Alastor shook the thoughts away, he would be able to get more of the sweet nectar. He just had to play their little game first. He moved back down to kiss Lucifer as he renewed his thrusts with vigor. The king moaned loudly in his mouth and tangled his fingers in Alastor’s bright red hair. The force of his movements caused Lucifer to slide up and down the door frame.
One particularly harsh thrust made Lucifer cry out in pain, “Fuck! Alastor please, can we move? This is really starting to hurt.”
The Overlord snarled slightly, without a word, he lifted Lucifer off of his cock completely. The king sighed in relief before yelping as Alastor flipped his around and snarled in his ear, “You better hold on.”
Lucifer barely had time to grab the frame before Alastor slid back inside of him, immediately the Radio Demon sought of his kings sweet spot. He looked down and watched as the pale, supple globes bounced with thrust. A growl slipped past his lips as he brought a quick hand down on one and moaned at the kings yelped and how tightly his hole clenched down.
He knew that he wasn’t going to last much longer, the effect of the blood plus the pressure in his stomach was too much. With a snarl, he pulled Lucifer off of the door frame. The fallen angel yelled at the force but soon it turned into a whimper as Alastor pressed the king’s back flush to his chest, one of Lucifer’s hands gripped his bicep in order to stay up right. The Overlord chuckled softly as he spread Lucifer’s milk white legs wide as he fucked into him, using him like one of the flesh lights Angel keeps leaving him as a joke.
He pressed a gentle kiss into the blond hair before him and grunted out, “I’m close, Sire. Touch yourself for me, please Lucifer.”
Lucifer moaned softly and Alastor peaked over his shoulder just in time to see a pale hand snake around an even paler member. Alastor hummed softly as Lucifer began to stroke himself in earnest. The king whimpered and moaned his name out, moving his hand even faster when Alastor slammed into his sweet spot. He only had to do so two more times before Lucifer arched his back and came with a cry of, “Fuck! Alastor!”
Alastor growled as the velvety walls clenched down on him. He watched as ropes of cum painted Lucifer’s stomach. The Overlord barely managed to pump in one more time before he slammed Lucifer down on his cock, spilling deep inside of him.
They stayed there for a moment, both panting as they came off their orgasmic high. Alastor still felt slightly dizzy from the blood, but otherwise he felt better than he had in months. Maybe even years.
But it wasn’t enough.
Slowly, he placed a gentle kiss on the side of Lucifer’s sweaty neck. The king hummed and tilted his head to the side, exposing the unmarked column. Alastor purred as he lapped at a spot with his tongue and placed a soft kiss there. Lucifer didn’t seem to react, so he bit down just slightly. Not hard enough to bleed, but he could make it if he wanted to.
“Just what do you think you’re doing?”
Alastor froze, gone was the meek and mild tone the king had used both before and during the coupling. It had been replaced by one of pure ice that sliced through Alastor. He put on his best cheery voice and replied, “Nothing at all, Sire! I had noticed earlier how much you had liked that action and I have planned on performing it again for you as a thank you.”
“Cut the shit, Alastor. How stupid do you think I am.”
With a snap of his fingers, the king was out of his arms and halfway across the room. His clothes and appearance were back to their pristine condition. He summoned his cane and twirled it in his hand, “If you really don’t think I can’t spot someone who’s after my blood from a mile away you’d be wrong.”
Alastor felt himself stiffen up. He opened his mouth to argue, but firmly shut it. Regardless of when Lucifer figured it out, there was no sense in denying it.
With his own snap, he returned his clothing back to their original placement. He turned to fully face Lucifer and let his smile grow as wide as he could, “Splendid! Who would’ve thought you had such keen instincts, Sire. Young Charolette must’ve inherited those from y-“
“Stop. Talking.”
Alastor flinched back as Lucifer’s more demonic features came out. His horns reached their full high and the fire between them burned bright. His long black tail thrashed against the floor in what appeared to be irritation.
Lucifer took a deep breath in and slowly exhaled it. He looked up at Alastor, “What we just had…That was something I had not experienced in so long. It was incredibly enjoyable. However, I can’t be freely giving out my blood to the likes of you, Alastor. I know your kind. You’ll keep using me until either you’ve grown bored or until you’re killed. I’m not interested in being used as your own personal food stash, at least not without it benefiting myself as well.”
Alastor narrowed his eyes and folded his arms behind his back, “Then what do you propose we do, Lucifer? I’d be a liar if I said our little, exercise was not enjoyable. You sound heavenly when someone is buried deep inside of you.”
The golden blush once more appeared on the kings face, “What I’m proposing is a deal, Alastor.”
A chill raced down the Overlords spine. He’s not used to anyone catching onto him. While the idea of him losing control of the situation somewhat worried him, having someone who could match him in wit thrilled him even more.
“What kind of deal, Sire? What you get to have my company whenever you please in exchange I can feast on you as I wish?”
Lucifer flinched slightly, looks like Alastor hit that nail on the head, and released a low growl, “Look who decided to use their brain for once. Sounds like a sweet deal for yourself. You get both my body and my blood. All you have to do is use that-“ He pointed to Alastor’s crotch with a finger, “to fuck me stupid and you can drink as much as you want. I will warn you, though, my blood will affect you. Most demons slowly go mad if too much of it is in your system. It could be the end of you. Plus I might be too much for you to handle.”
Alastor scoffed and casted his eyes down to inspect his claws, “You talk as though I don’t have a sense of control, Sire. I restrained myself for this long, surely I can pace myself in between meals. Plus I had no problem handling you as you screamed my name just moments ago, I’m sure I can take whatever you dish out.”
Lucifer smirked and crossed the room. He stopped just in front of Alastor and held his hand out, the flame between his horns grew large as he said, “So, we have a deal then?”
Red light flooded the room, Lucifer’s eyes turned the same shade and his voice grew deeper, more demonic. Alastor swallowed hard and extended his hand. As soon as they were joined, he found himself on his knees with his hands behind his back. Cool metal encircled his wrists and his ankles, connected by a longer chain. A collar appeared on his neck connected to a long golden tether, the ending of it landed in Lucifer’s hands.
The Devil smiled down at him, slowly his demonic features faded away and Alastor was left with Lucifer looking positively beaming, “Good boy, now then, you may be full but I am still hungry.”
With a flick of a finger, Alastor’s clothes were gone and the door behind him was shut and bolted. A sharp thrill of both fear and arousal passed through the demon. Panic threatened to take over, but he squashed the feeling down. He simply smiled up as Lucifer as he bent down to grab Alastor by the hair.
“Oh this will be fun...”
