Asmo/you
The first night it happened, Asmo had been righteously indignant, and irritated. He was a very important demon after all, and he needed his beauty sleep!
It was the middle of the night when he was awoken by the odd sound. Sensitive ears picked up the sniffling cries, muffled by the walls and what he believed was the blankets. His eyes snapped open and the irritation dissipated. The direction of the crying was from the right, which meant it was the exchange student's room.
What an odd human. You had been fine in their presence all day, minus the pounding of your frail heart. Or perhaps not so odd. You had been basically kidnapped, after all, at the whims of Diavolo no less.
Yet you had rather stupidly and maybe bravely plastered on a smile, fraying at the edges, as you tried to navigate. Like a baby deer unsteady on your legs just yet. It seemed your bravery had faded with the day as you now cried quietly in the safety of your room.
Truly, it was cruel. To pluck a weak human like you from the safety of your world and give them to Mammon of all Demons. Asmo snorted. You'd be dead within a week under these circumstances.
If he did anything to you tonight, Lucifer would have revenge. You were integral for Diavolo and his dreams, so Asmo couldn't kill you off for disturbing his sleep. Tragic. Growling lowly, he rose from the bed. If he couldn't sleep, then there were plenty of other uses, and beings, he could use a bed and his time for.
The crying continued for the next few nights, but died down once Mammon, the moron, had formed a pact with you. Not that you'd stopped the pathetic sniffling, oh no. You wore smiles in the daylight, heart still terribly pounding, as you lied to them all you were okay. You didn't know they could smell the fear, was attuned to it, and that the smell was alluring to their darker inclinations.
But Mammon was now caged, by both Lucifer and you yourself, trapped. He couldn't hurt you now, and neither could the others except Lucifer himself. Mammon was more in tune with your emotions now, and was going to your room nightly, calming you down with his stupidly clumsy moves. Mammon liked you.
Asmo sighed. Two stupid people would be drawn together like moths to a flame. At the least he could sleep again, even if they couldn't intentionally manipulate your fear anymore. Mammon would be too loud and annoying to deal with if they did.
Your confidence had built under the clumsy demons machinations. You began to be well rested, and though you struggled with the course work, you didn't complain. That was a plus.
You were attractive. But still so pitifully weak. Once, Asmo had been bored and under the sway of his sin. Solomon had been busy, and Asmo felt like having his dessert in that night, rather than going out. He'd toyed with you half seriously and half curiously. Hanging out with Mammon, Levi, and Beel hadn't influenced you as it would most humans. But could Asmo sink you into unbearable heat and lust?
Caging you in his arms had been easy, as you looked at him with curious eyes. His words, low and filled with warmth, with promise, dripping in his sin, coaxed you forward. Hand wrapping around the delicate curve of your throat, feeling the pulse flutter and pound beneath fingers. Fanning his breath over your cheek intentionally to feel you shudder under him. Half lidded eyes had watched your chest expand with your breaths before he'd dismissed it, licking his lips to draw your gaze.
"What do you say, Y/N? A night with me would be infinitely better than whatever Levi wants you for."
As he spoke against your ear he'd applied pressure to get you to bend your legs, lowering your body to the couch. He didn't surrender his weight to you, but did crawl down as well, hovering, caging you in further. Legs trapping yours, one hand caressing your throat still, the other scraping along your scalp in a half massage. Your hair was cool against his fingers while your face was reddening more and more. He wanted to tug your shirt down, to see the blush extend elsewhere.
"It's a…" He distracted you by tugging your hair a little. "A new d-dating sim. I- I promised I'd play it with him."
Asmo cooed at your voice. So soft and unsure. He'd have you demanding and begging all at once soon. "What sounds better? Some simulation that can't really warm you up? Or reality? I know you're smarter than that."
Then he smelled it, mixing into the arousal he'd managed from you. Fear. You were right to be afraid, after all. One of the classes detailed perfectly what a lust demon could do to a human, and he was the patron to the sport. But that sudden burst of fear meant only one thing would happen now.
Mammon burst in loudly and you'd jumped, body pressing against Asmo's for a brief moment. The greed demon took one look at the scene and Asmo preened at his jealousy.
"Oi! Get off of them, you pervert!"
His chuckle low and breathy, he gave you a look of mock hurt. "So rude. You didn't have to summon your guard dog on me, Y/n. I'm hurt."
Confusion cut through your eyes. You hadn't meant to summon Mammon. And truthfully the fear had been but a short burst, quickly overcome by the way Asmo controlled the room.
Asmo smiled, booping your nose. He'd leave you wanting, as a punishment for ruining his fun. "Oh well. Next time, Y/N! Now I simply must be off. It'd be a crime not to let others see my beauty after all."
You were very confident by the time Asmo made his pact with you. You didn't shy from his flirts, but now Asmo was hesitant to take what he knew he could have. Without manipulation. He actually, que shudder, cared about you. And didn't want a messy one time thing, although he would make sure it was memorable.
Lust came in many forms, and he was the sins patron demon. He felt it all, at all times. He just chose to allow it to manifest as lust for attention. He believed it, too. He was the best-looking Demon around, period. No one held a candle to his looks, nor his prowess with his sins many facets. He earned and deserved all the attention he was lavished with. And now it barely covered what he needed.
Getting you on his lap for five minutes uninterrupted to cuddle, or running brushes through your hair, swiping on cosmetics or lotions, fed him more than a night with the wildest of demons. He wanted your attention, and when he had it, he absolutely feasted.
Then Belphie happened. Your corpse bloody, and broken, tossed before them like a doll. He'd once relished watching as little gasps left your body, cooed at the sight of red decorating your skin as he or one of the others toyed with you. Now, gasps tore for the wrong reasons. Red covered you like a hideous blanket. Mammon was the one brave enough to cling to you, while the others stared in confusion or anger. Sorrow.
Asmo was not any of those things. What he was, was lust. And it came in many different forms. Blood lust being the rarely indulged facet that he hid. But he craved it now. Itching and burning through his veins. Demanding, as he felt his pact mark sear into his skin, demanding he protect the human. Protect you, except he wasn't an Angel who could influence life. He was a demon. Your life was forfeit, now.
Lucifer had blocked him, despite Asmo hissing and lunging. "Control it," he'd snapped out.
All Asmo wanted was for Belphie to bleed, to match what he'd done to Asmo's master. Lucifer had a tight grip on him though. The lust demon could kill Belphie in terms of strength. But he couldn't overrule Lucifer.
Then you were gone, amidst the wild cackles of Belphie. Then back again, trembling and more afraid than you'd ever been. When Belphie had made a move against you, Asmo had found himself moving quicker than even Mammon. In front of you as you fell back, unintentionally sending out summons for all your pact demons. You drug them all into their true forms, only Lucifer immune to the call.
Diavolo had came with Barbatos then. The situation cooled but you did not. Your mind, so beautiful and adaptable… part of it was most likely broken. You had watched yourself die. And by the interference of Barbatos, combining the timelines, you now knew the feeling of it too. The way your body had ached before going numb, the way true suffocation felt. You knew the feel of the banister cracking against your weight before it gave and you tumbled down to the first floor.
Every day, and through the night, screams and cries echoed through the house of lamentation. Lucifer did his best. As the only one not in a pact, you couldn't force him away, intentionally or not. Asmo, nor the others, were getting any sleep. Unlike before, he didn't leave the premises or wish Mammon would mess up and leave you alone. He settled back and simply listened to you, listened to Lucifer employ soothing tones to his smooth voice. Sometimes, he could talk you from your delusions and nightmares. Others, he resorted to spelling you, the house of Lamentation becoming heavy with the smell of ozone from his magic.
Lucifer was heavy handed, yet effective. Your name came up often during the council meetings. Asmo hated it. They debated wiping your memory of the devildom, of breaking your pacts. How could forgetting HIM lead to your betterment? Asmo snorted.
He argued against it, of course. As did Mammon and Levi. Satan remained tight lipped, and when pressed, he merely spat out he was thinking of your betterment only. No one could deny the rage swirling around him when it was brought up or Belphie was near him. Only Beel kept his mouth shut, miserable looking and broken in his own way. The Brother he cherished had taken their Y/N away, one way or another. Asmo felt his bloodlust simmer and boil, but he didn't act.
They had all hurt the blood of Lilith more than could be accounted for in one way or the other, all of them except Mammon.
Lucifer had finally calmed you enough, broken through enough, for you to come to breakfast. Weeks had passed since any of them besides the first born had seen you. You looked terrible and Asmo ached for it. Hair a mess, night clothes rumpled and too loose. Lucifer barely got you to eat.
You seemed at the least soothed by their presence now, rather than fearful. Levi even got a small smile from you, and a promise to watch some boring anime he'd been saving just for you. The long winded title made them all roll their eyes.
Your appearance alone made them aware you weren't going to school, which prompted Satan to mention he'd been quietly collecting and then turning in your work for you. Dumbing it down as well, most likely, as no way you or any of them except Lucifer could churn out a Satan level report.
It almost felt… normal. You felt normal. Enough so Asmo had tutted and clicked his tongue, coming behind you to finger comb your hair.
"Honestly, Y/N! It's okay, I'll take care of this for you. You have to take pride in yourself. I mean, you're the most beautiful thing, besides myself of course. What would you do without me?"
He felt the grease on the limp strands. Internally he shuddered, but soldiered through. For you, everything for you.
"You don't have to," you murmured. Voice hoarse from all the screaming and lack of real use in the last week.
Asmo giggled lightly. "Now, now! No fuss, Y/N! It's an honor to be fussed over by me."
You're returned giggle made them all relax a little. The way you relaxed back as he massaged your scalp soothed them all. Your heart was placid, normal.
Then it ended. Belphie came in, late as usual, settling next to Beel. Your heart jackhammered. Breath sped up enough to be noticed even if they weren't demons. Asmo didn't hesitate to move to stroking your neck, relaxing the tense muscles there. He hoped it soothed you. And it did, enough that you were able to sit there still. You stopped eating though, and were pressing into him as much as you could.
When it happened, no one could blame Asmo, but he knew Beel did. Maybe Lucifer too, for he usually had better control. The others didn't judge, as he merely did what they wanted to do. They all loved Belphie. But love didn't negate the fact he'd broken something they all cherished.
"Y/N, you aren't eating. Here, try this." Beel had dropped a fluffy pancake onto your plate, his large hand making you flinch a little but you smiled. Toyed with a fork and poked holes into the food covering your plate.
Asmo tipped your head back, a piece of food in his fingers. "Oooh Y/N, let's feed each other! Doesn't that sound romantic?"
"Oi! If anyone is gonna feed them it'll be me!" Mammon said. A little off beat. He wouldn't lunge, too worried for your mental state.
"Oh shush, Scum bag. Y/N would love to feel my fingers in their mouth, right?" He pressed the piece of food between your lips, pleased when you opened and allowed him to place the morsel against your tongue.
"Keep it appropriate, Asmo," Lucifer sighed in resignation.
Levi was blushing and fangirling. "This is exactly like when in 'Help I've been surrounded by multiple-"
"Beel, pass them the syrup. Dry pancakes can't be that appealing." Satan grinned wickedly, eyes locking with Asmo's. He didn't want to get sticky fingers from the syrup and they all knew it.
Still, when the syrup spilled across the tablecloth, red and thick, and also against the lethargic seventh borns arm, you broke.
"Watch it!" He'd snapped tiredly. If Asmo had to guess, his tone had caught you. And the way the red looked.
You shrieked, would have fallen backwards had Asmo not been directly behind you, and you panicked more when you couldn't throw yourself away. Asmo clung to you, feeling the way you turned and clung to him. Felt and heard your heart speed up dangerously, smelled the sweat suddenly pouring from you along with tears and terror.
"What the-" Belphie began.
Asmo didn't let him finish. His eyes flashed, and Belphie slammed into the wall behind him, grunting as his body dented into it before slipping to the floor.
"Belphie!" Beel had gotten up, despair and worry clouding his vision before he turned angry eyes to Asmo. They faltered when they took you in, clinging to him like a second skin at that point.
Took note of the deadly aura around Asmo. Beel was physically stronger. But Asmo wasn't playing by strength of body and never did. They all felt the telltale feeling of his influence, giving them desires to tear something or someone up.
All while you sent out signals to keep your pact demons away. All except Asmo, who you clung to in delirium.
He lifted you into his arms, shushing you. He glanced to Lucifer. "We'll be staying home today."
The lust demon saw Lucifer nod, before he used his own influence and magic to calm them all down.
Asmo took you to his room. You were filthy, after all, and he only knew of certain ways to calm someone. His bath was always full with cleanly scented water, magically equipped to become the perfect temperature. It was his pride and joy. Where he stripped off the sweat and smells of his sin. He stepped into the tub with you, clothing still on. He didn't relish the way it felt, but he ignored it while he held you close in his lap.
He dropped water onto your head with his palm, massaging it in until you became boneless against his form. He would eventually strip you both, cleaning your body tenderly, before wrapping you in a sinfully soft robe and depositing you into his bed. Going forward, so long as you didn't push him away, he would take over your care, until they either took your memories. Or you came back to them… to him.
