Chapter Text
It was a day like any other in Devildom, but lucky for you it was the start of the weekend. Friday after school was really the most exciting time of the week for you and the demon brothers, full of possibility. Today, Asmo happened to get to you first once you were back at the house.
"Hiii! Do you want to go to Majolish with me? They have the most adorable outfit I just have to have, and I think it'll be fun to have someone as cute as you with me," Asmo said with a giggle, twirling your hair before tucking it behind your ear.
"S-sure," you replied with a timid smile. With that, Asmo looped his arm with yours and led you to the front door.
Once you made it to the entrance hall, you heard an all too familiar bored hum coming from above which could only mean one thing: Mammon was strung up from the chandelier. Looking up to confirm it, you were met with Mammon's golden-sapphire eyes looking down at you.
"O-oh, it's you," he almost mumbled before immediately putting on a more brave appearance. "Oi, whatcha doin' with that guy?" he asked while gesturing towards Asmo with his head.
"That guy is your fabulous brother, thank you," Asmo huffed. "And we're going on a date to go shopping."
"D-date?!" Mammon shouted with red cheeks while yours turned to the same color.
"It's not a date really," you said as nonchalantly as possible. You wouldn't mind being on an actual date with Asmo, but it always bugged you when any of the brothers played up what you were doing just to annoy one of the others.
Mammon looked to the side, poor thing just motionless with his entire body bound. "W-well, whatever..."
"Do you want me to help get you down?" you suggested, looking from Mammon to Asmo to see if he'd help, only to find him completely disinterested.
"Ah, nah. I don't wanna get ya dragged into this. Lucifer is gonna get a big ass whoopin' once I'm down from here though," Mammon said with a slight scoff. "Uh, you should both probably get outta here. He's super pissed today."
Asmo wasted no time and grabbed your wrist, pulling you with him to the front door. You looked back at Mammon with a worried expression. Why the hell did Lucifer have to be so aggressive? You caught Mammon's signature cheeky smile as you walked out the door, but you knew you saw it slightly falter.
⋆⋅⛧⋅⋆
Your experience shopping with Asmo was fun, but you were distracted nearly the entire time worrying about Mammon. You knew Mammon could be a little shit sometimes with stealing people's things, but you also knew there had to be some underlying reason why he did it. He didn't obsess over taking things or using other people's credit cards just to be a "scumbag".
Since Lucifer showed how openly aggressive he was with Mammon in front of you and the brothers, you wondered what did he do to Mammon in private? The entire thing made you sick to your stomach. The longer time went on in the day, the more you became worked up about the entire situation.
After making it back to the house, you noticed Mammon was no longer strung up. Asmo noticed you looking in every direction as you walked with him towards his room, and he said with a tsk, "Don't worry about that fool. He deserves whatever Lucifer did to him."
You stopped in your tracks, letting go of Asmo's arm as your fist clenched around your shopping bag. "How can you say that?" you said nearly at a whisper.
"Hmm? I mean, it's obvious. Mammon is nothing but a cheap scumba-"
You rushed off towards your room, ignoring Asmo's calls after you. You slammed your door behind you, tossing your bag to the side as you sat on your bed with your face in your hands.
Why did you care so much? Why were you getting so upset about this? You loved all the brothers and hated them fighting, but Mammon was their punching bag. Literally.
And for what? All the brothers are just as troublesome at times in one way or another.
Lucifer is often a prideful tyrant who gets off on controlling and punishing people when they do anything he doesn't deem appropriate. Mammon sometimes steals money and valuables. Leviathan can be self-sabotaging to the point it's exhausting. Satan can be generally rude and inconsiderate. Asmodeus can be so obnoxiously flirty and self-absorbed. Beelzebub can eat everyone's groceries without asking. Belphegor can be extremely cynical and apathetic.
They all have their faults, and hell, so do you. Everyone does. But they each have way more great things about them that you love and that they love about each other. So why was Mammon always the one singled out and punished for his innate sin?
Just as you felt you were on the verge of angry tears, your D.D.D. vibrated in your pocket. You unlocked the screen to see a message from Lucifer.
"I need your assistance with paperwork. Meet me in my office."
You sighed and stuffed your phone back in your pocket. You walked over to the bathroom to splash cold water on your face, appreciating the cool, relieving sensation. After touching up your makeup, you made your way over to Lucifer's office, still no sign of Mammon along the way.
You hesitantly knocked on the door, waiting a few seconds before Lucifer appeared before you. "Ah, glad you could make it," he said with a slight bow and charming smile.
God damnit, right now you hated that you found him attractive. You wanted to be mad at him, but he knew just how to get your affections. Still, you stood strong. "What do you need?" you asked plainly.
Lucifer chuckled and led you into his study, motioning at several enormous piles of paper. "Rejected applications for R.A.D. I was hoping you could help make sure their information matches our records, then sign off on it at the bottom."
"Fine, let's hurry this up," you sighed.
Lucifer made his way to your side, resting his hand on your lower back. "May I ask why you're in a rush?"
His smooth, deep voice made you pissed. Pissed because of the delightful shudder it sent through your back, and pissed because you knew you wanted to stay mad. You shrugged your way away from him and dragged one of the large chairs over to the corner of his desk.
Lucifer laughed to himself as you grabbed a stack of papers and a pen, immediately getting to work. He sat in his desk chair across from you, and the two of you began your work in silence.
You eventually found yourself getting a headache and becoming increasingly distracted. After letting out a particularly loud, drawn out sigh, you immediately felt Lucifer's eyes on you. You looked up from your papers and were met with his dark stare. "What?" you asked in an annoyed tone. Normally you never talked to Lucifer or anyone like this, but you couldn't hold back from expressing your frustration.
Lucifer neatly placed his pen down and leaned back in his chair. "Is there something I've done to upset you?"
"Actually, yeah," you spat. "I think the way you treat Mammon is shitty."
"Ah," he said with a chuckle, only spurring your anger further. "Well then, it's unfortunate you feel that way."
"It's unfortunate you see Mammon that way. You don't string up Beel when he raids the fridge or breaks things." Your words were coming out fast, flowing from you without even thinking.
Lucifer nodded, saying, "That might be true, but-"
"You don't torture Levi when he floods the entire fucking house summoning Lotan!" You were raising your voice by now, sitting straight up as you glared at Lucifer.
Lucifer's eyes widened just the slightest bit. Having never seen you like this was certainly different. "Y/n, there's a good reason why Mammon serves the punishments he gets."
"Oh yeah?! And what is that??"
"He needs to learn from his mistakes and maladaptive behavior," Lucifer replied calmly.
"Ha! Maladaptive behavior?!" You didn't give Lucifer the chance to respond. "You're supposed to be the leading example for all your brothers, or at least that's how you showcase yourself. Yet you have the audacity to torture one of your brothers on a regular basis. You ever wonder why they all call Mammon a scumbag? Because of you."
Tears stung your eyes by now, but you continued. "You're setting the precedent for how they interact with him, and you're normalizing violence against your brother."
"Y/n, you don't understand the nuance of what you're talking about," Lucifer said as he reached his hand towards you.
You batted his hand away and stood up, tears silently rolling down your cheeks. "You don't understand. I love you just as much as your brothers Lucifer, but you can really be such a piece of shit sometimes." Just as Lucifer opened his mouth to respond, you rushed out of his office.
You couldn't believe what you'd just said to him or that you'd just walked away from the task he gave you. You never expressed yourself like that to Lucifer or even had a remotely confrontational conversation, yet here you were storming off away from him, turning down the labyrinth of hallways to the nearest exit. You were in nearly a sprint as you burst out the door into the side yard, finally reaching a full sprint towards the garden as the chilly air stung your tear streaked face.
You eventually slowed, your adrenaline wearing off as you suddenly felt tired and drained. Once you walked between the garden hedges, you paused to take a deep, calming breath and wipe the tears off your face.
"Y/n?"
Your heart jumped while startled from someone calling your name. You quickly turned to the source, seeing a white haired demon making his way to you. "H-hey," you replied in a shaky voice, clearing your throat in attempt to speak normally. "What are you doing out here?"
"Oh, ya know, it's.. just a nice night out," Mammon said while rubbing the back of his neck. "I could ask ya the same thing, dontcha think? It's dangerous to be out here by yourself, ya dumb human."
You laughed and were genuinely happy to see him acting normally. "Yeah, you're right. But at least you're here now." Even in the dim moonlight, you could see the blush dusting his cheeks.
"S-so, uh... D'ya wanna chill with me out here for a bit?" Mammon asked with his hands shyly in his pockets.
You smiled in return and nodded, taking his arm in yours and leading him to your favorite spot in the garden. You plopped onto the tall, soft grass and admired the arching shrubbery decorating the area in front of you. Mammon took a seat next to you, leaving a little space between you two.
You sat in silence for a while, appreciating the nighttime wildlife sounds and the occasional creaking of the huge trees behind you. You contemplated what to say to Mammon. You wanted to tell him everything you're feeling, yet you also felt more than content just spending time with him and feeling his relaxing energy.
You looked over to him to see him gazing up at the stars, and you could tell from the puffiness beneath his eyes he'd been crying as well. "Mammon," you murmured without choosing to do so.
His striking blue-gold eyes pierced through the darkness as he looked at you. He could tell by the look on your face that you knew he'd been crying. "S-sorry, it's been a weird day," he mumbled as his eyes shifted to the ground.
"Please don't be sorry," you responded, looking at his hand fiddling with the grass between you.
"I just... I'm... Gah, I dunno. I'm a mess," Mammon sighed, hanging his head low.
"We all are," you responded with a reassuring smile. "We all do things we shouldn't sometimes."
Mammon's eyes met yours again. "Not you, though. You're perf-... I-I mean, uh..!"
You giggled and said, "Perfectly dumb?"
"Y-yeah, that's what I was gonna say... just a dumb human," he mumbled.
You couldn't help but smile as you looked into his sincere eyes. You'd always been close with Mammon, and it was nice to see him be a bit more vulnerable with you, even if he was still keeping up a little bit of a facade that you could see straight through.
You turned your attention back towards the beautiful flora of the garden, then to the night stars decorating the sky. You found yourself getting cold, but you didn't want to go inside yet. Instead, you pulled your knees close to you and wrapped your arms underneath for warmth. You still needed to ground yourself and refocus before going back in and possibly running into Lucifer.
Mammon started shifting around next to you, and it wasn't until his hands brushed against your shoulders that you noticed what he was doing. He'd removed his brown leather jacket and draped it around you, making sure to smooth it down in place so it would be snug around you.
You thanked him shyly and asked, "Won't you be cold now?"
"Nah, I'll be fine," he responded with a smile, bringing his hands back to the ground on either side of him to prop himself up. "I guess I could just.. y-you know, move closer to ya or somethin'."
A smile graced your lips as he closed the small gap between you, letting your legs just barely touch. Mammon's entire body tensed up after he moved towards you, but you could feel the moment he eventually relaxed. The butterflies in your stomach seemed to spread throughout your entire torso, and that's when you realized just how strong your feelings for Mammon were. Being wrapped up in his jacket brought you so much warmth, to be surrounded by his comforting scent while also right here next to him.
Just as you were getting truly lost in your thoughts about him, you felt his arm wrap around your back. You felt your cheeks warming to a point it was nearly unbearable, and you took a deep breath to calm yourself. "Just so you know... I kinda flipped on Lucifer for what he did to you." The words seemed to escape you without thought.
Mammon looked at you with wide eyes, wondering how the hell the relatively new human exchange student had the guts to stand up to such an intense guy. "Ah, why'd ya do that? Ya didn't have to."
You looked at Mammon sternly as you replied, "Of course I didn't have to, but I'm sick of his shit. I'm tired of him treating you like this, to see you tortured every single week." Your eyes ventured down as you felt tears pricking at them again. "You don't deserve that...."
You half expected Mammon to do his whole 'I'm the Great Mammon' spiel, but he simply stared at you with his mouth slightly open as if he wanted to say something but couldn't. To have someone for once accept him for who he is was unfathomable. Over the years, he'd started doubting who he is, believing he was nothing more than the one word he was always referred to as: a scumbag. The confusion and doubt would build up and eventually boil over, resulting in anger and tears like it had today. Yet here you were saying the complete opposite.
"I just don't get it, Mammon," you continued. "You're the only one ever punished for your sin this harshly on a regular basis. And..." You threw your arms around him and hid your tear streaked face against his shoulder. "I wish they would see what I see in you," you mumbled while gripping his shirt.
Mammon's heart was jolted as if you'd electrocuted him with your words. He never in a million years thought his human would care about him this much. He always assumed he'd be endlessly chasing after you while simultaneously denying his feelings for you. His arms wrapped tightly around you as silent tears slowly rolled down his cheeks. He silently slid his hand down the back of your head repeatedly to comfort you. You felt guilty for being the one getting comforted when you felt you should be doing the same for him.
"I...." Damn, what did he want to say? What could he even say? He wanted nothing more than to make you happy, but you were here crying for him. "I gotta be honest. I don't exactly like it either. But if it keeps my brothers from gettin' treated that way by Lucifer too, I'll be the one to take all of it. Hell, I've taken the blame for stuff I didn't do just to protect my younger brothers. And even if they blame me for everything now, it's worth it to keep 'em outta harm's way."
You looked up at Mammon in awe. You knew he was an incredible guy, but the fact he put himself through so much just to protect others was certainly nothing to scoff at.
Mammon rubbed your back reassuringly with a soft smile. "Ya don't gotta worry about me. I'll be alright no matter what, especially if you're by my side."
Your heart felt as though it flipped as you looked into his otherworldly eyes, your tears ceasing the instant he tucked your hair behind your ear. A warm tingling sensation lingered on your cheek where his hand brushed against you, and you found yourself chasing the feeling. You took his hand and brought it to your face, nuzzling against it.
A beautiful pink hue splayed across Mammon's face while he watched you. His heart raced as he slowly brought his lips to yours, looking for any hesitation or doubt from you along the way.
Of course, he found none. He could feel from the way you kissed, the way your hands continuously roamed over his body that you wanted to be close just as much as he did.
Mammon deepened the kiss, sliding his tongue along your bottom lip before you gave him access. A soft sigh escaped you that had Mammon absolutely melting, unable to believe he could bring such a sweet sound out of you. You felt his smile form against your lips, a smile that soon turned into his innate need and hunger for you.
You kissed him with a fervor you didn't realize you had in you, and you found yourself burning up from every kiss, sound, and touch coming from Mammon. You broke the onslaught of kisses only to swing your leg over his legs, straddling his lap. Mammon's face tinted incredibly red as he looked at you with wide eyes.
You bashfully looked to the side, wondering if maybe you took things too far too quick. "Sorry... is this okay?" you asked quietly.
You were met with Mammon's lips crashing back into yours while his hands gripped onto your hips. "Don't be sorry," he breathed between kisses. His hands felt so hopelessly needy on you, grabbing and sliding over you. Your entire body heated up as his hands put you in a rhythmic motion, pushing you down as your pussy rocked back and forth over him. Even through clothes his cock felt amazing.
Mammon opened his eyes as your lips broke away from his, only to see your adorably blushing face. To hear and see you moaning over him made him feel beyond incredible. To think that his human was willingly here so open with him. Every pant and sigh, every facial expression, the need he could see you had for him... and you were wearing his jacket. It was all just way too much.
"Wait, wait," Mammon said in almost a panicked voice, holding you still as he nuzzled his face into your shoulder.
"What?" you panted, trying to steady your heavy breathing.
"Y-you, uh... I... I was about.. t-to...."
You were glad Mammon couldn't see the smile on your face and become even more embarrassed, because god damnit he was adorable, and you couldn't help it. And truth be told, you were getting close to climaxing as well which wasn't exactly the way you'd imagined your first time with him would go. You maneuvered yourself off of him, opting instead to lay in the thick grass next to him.
"W-what are you doing?" Mammon asked with wide eyes looking straight at you. "A-are you done? I-I mean, it's okay if you are, but-"
Your giggle made Mammon's deep blush immediately return. "I wasn't planning on being done yet." Truly, your clit was throbbing, and having the cool night air on your thighs instead of Mammon made you realize just how wet you actually were.
You gasped as Mammon suddenly pounced onto you, his glimmering eyes making you feel hypnotized just before his soft lips mingled with yours. You were instantly cast back into the depths of pleasure with him. You threaded your fingers into his soft hair as one of his hands slid down your stomach. His hand slipped beneath your panties, fingers sliding between your lips to rub your clit. He moaned into your mouth as you spread your legs open for him, your hips rolling and chasing after his touch.
Mammon loved your eagerness and rewarded you by slipping one of his perfectly long fingers inside you, quickly followed by another. Your lips separated from his as you cried out his name, your back arching from the unfathomable pleasure. A sinful growl escaped Mammon as he heard his name coming from you in such a salacious manner.
You continued moving your hips, fucking his fingers desperately as you cling onto his black T-shirt. You felt yourself getting more wet by the second, absolutely covering Mammon's hand in your slick essence. Mammon was just as pleased, moving to lift your shirt up with his free hand, his fingers steadily pumping in and out of you. "Fuck," he whispered as he saw your tits pushed up so nicely in your bra. He quickly started worshipping them, licking all over and burying his face in your cleavage. You gripped tightly onto his hair, earning a pleased growl from him that made you shudder.
Mammon pulled your bra down, allowing your tits to be more accessible, your cute nipples readily available for him. His lips instantly latched on one, his deep moans vibrating into your chest. He increased the speed of his fingers inside you, making you writhe with pleasure. His tongue continuously flicking your nipples, back and forth between the two, had you seeing stars. Just as your body started to shake, Mammon kissed his way up your chest to your ear, nibbling the shell of your ear before saying, "Mnnn, are you ready for my demon cock?"
Not a second later, you were cumming on his fingers, your eyes fluttering closed as you moaned his name mixed with a series of curse words. Mammon absolutely ate it up, seeing you lose it just for him. He slowed his finger's movement inside you as he watched you intently, making sure to match where you were in your descent back to baseline.
Once you opened your eyes again, you were met with his gaze, a mix of pride and awe on his face. You blushed from seeing just how incredibly attractive he is, especially in such a vulnerable state like this. "Mammon," you murmured softly, placing your hand on his cheek. His reaction of nuzzling against your hand was more than adorable.
"What is it, darlin'?" he asked as a captivating blush spread across his face.
You made your pussy clench around his fingers, making him immediately drop his jaw while his eyes widened. "I need you," you replied with a passionate gaze.
Mammon shuddered as he pulled his fingers out of you, kissing you as you flinched from the sensitivity. You instantly felt the need for him growing exponentially as every second passed. Mammon then sat up to remove his shirt, revealing his gorgeous skin. You sat up as well, your lips instantly drawn to his neck. As you kissed, sucked, and nibbled his neck to make a lovely mark, Mammon groaned as he unfastened his belt and pants. The fact that his human was so willingly leaving a mark for everyone to see had him feeling incredible.
Your eyes shot open as you felt his cock smack against your stomach as he freed it from his pants. After removing your panties while keeping your skirt on, you soon felt him aligning it with your entrance, and you couldn't help but look down to watch him enter you. You silently gasped as you saw his large cock sliding effortlessly into you, as if he were made for your pussy. Mammon groaned as he bottomed out, then slowly dragged out before going back into you.
You let out a loud moan, already losing yourself. You shimmied off his jacket, then removed your shirt and bra. Your mouth opened noiselessly as his thrusts increased in momentum.
"Mmn- keep my jacket on," Mammon panted.
You obediently nodded your head and put solely his jacket on, leaving your chest otherwise bare. Your hands were shaking from the overwhelming building pleasure in you, making it difficult to get his jacket on properly while also propping yourself up. Once in place, you wrapped your hand behind his neck for support as your head tilted helplessly back from the sexual tension building inside you.
Mammon took the opportunity to attack your neck with his sharp, demonic teeth, leaving a love mark of his own on you. As you cried out in ecstasy, Mammon lowered you to the ground, his hips never wavering in their relentless pace. He was maniacally obsessed with hearing every noise he could from you, to bring you to unknown heights of pleasure while he was drowning in bliss as well.
His cock pummeling into your pussy left you weak, nails digging into his back in some frail attempt to ground yourself. You'd never felt this incredible, this lost in salacious indulgence in your entire life. Mammon's body shuddered as your nails sunk deeper, making him grunt and groan in a carnal way. "Fuck! You're so damn hot," Mammon breathed as he lifted himself up just enough to see your flustered, blissed out face and your tits bouncing with each rough thrust.
You found yourself unable to respond aside from loud moans. As much as you wanted to brag about how incredible he made you feel, to feed into his greed in the best way possible, you just couldn't above the incoherent noises escaping you.
Mammon's white hair looked nothing short of ethereal in the Devildom moonlight. It shimmered just as brightly as his eyes that focused on you so intently. Every breath and groan of his sounded so ungodly erotic, each time taking you to a new height of euphoria. Looking down from his perfect face to his chest, then his delicious abs, eventually your gaze landed on his cock pounding into your pussy, making you squeal at the sight.
"Mn, ya like that, baby girl? Watchin' me slam into that cute, tight pussy of yours?" Mammon's husky voice drew you momentarily out of your lust drunken haze. His heart absolutely melted as he saw your big eyes look up at him so genuinely as you nodded your head in agreement. He could tell he was the only thing on your mind, and his greedy soul was devouring every bit of that.
Mammon's pace quickened again, making your pussy tighten around him as you tried to adapt to the onslaught of thrusts. His hand grabbed onto your breast, kneading and squeezing while his mouth returned to your neck, this time leaving a deep mark on the opposite side from the other. "Tell me you're mine, baby," he groaned just above a whisper next to your ear.
"I'm- I'm yours," you replied between gasps and moans.
A growl emitted from Mammon before he propped himself up a bit. He took both your wrists and pinned them down beside either side of your head. For a moment, it looked as though he had tears pooling in his eyes, but you hardly had time to think about it before he said, "Please tell me I'm yours."
Without hesitation, you responded, "You're mine, Mammon."
All at once, his lips crashed into yours as he threaded his fingers with yours, holding your hands tight while his thrusts became incredibly fast and haphazard. Your body seemed to light up with electricity pulsing through every single nerve. "Cum inside me," you mumbled against his lips, which he very clearly understood. Your tongues and bodies melded into one as you soon were cast into the peak of your climax, your entire body vibrating as your fingers wound tightly around Mammon's.
Mammon seemed to forget every word other than your name as his cum pumped into you, the forceful pulsing of his cock only spurring your pleasure further. Despite occasionally breaking away to breathe your name, Mammon's kisses remained purposeful and sensual, each movement of his lips and tongue so perfectly synced with your own.
As his hips eventually slowed, he grabbed your hands tighter, almost as if afraid to let go, afraid you'd leave the second he did. If only he knew how much you absolutely adored him, how much he meant to you. And seconds later after leaving kisses on your neck, he blurted out the very question on his mind. "Did you mean what you said?"
You couldn't help but instantly giggle, making Mammon whine and hide his face against your chest. The fact that he could even doubt for a second that you didn't mean it was absurd, because of course you did. Mammon meant the world to you, and tonight solidified that more than ever. "I wouldn't lie to you, Mammon."
Mammon's head shot up as he looked you in the eyes, glimmering with hope. "R-really? So that wasn't just like.. ya know, in the moment stuff?"
You nodded your head affirmatively. "I meant every damn word." You blushed and giggled as Mammon smothered you in kisses as he found himself absolutely ecstatic about your response.
After his kissing attack turned into a few more soft, sensual ones on your lips, he looked at you in astonishment through half lidded eyes. "You look so damn cute wearin' my jacket," he said with a smile that had your insides melting.
"And you look so cute with these," you said while gently flicking one of his horns.
"Gah!!" Mammon reached up to touch his horn, squinting from how abnormally sensitive it was from your touch. "Shit, when did I transform?"
"Not sure, honestly," you said with a shrug, opting instead to play with his wing. "Sometime around when I claimed you as mine," you said with a devious smirk.
"Why are you so fuckin' adorable?! It ain't fair," Mammon mumbled as he finally pulled out of you, making you both shudder at the sudden sensation. "C'mon, let's get ya warm with a bath. We've been out in the cold for too long."
You nodded in agreement, standing up and fixing your skirt and Mammon's jacket back in place on you, not bothering to put on the rest of your clothes. After Mammon put his shirt on, he wrapped his arm around you and placed a kiss on top of your head as you walked towards the house, making you feel more safe, warm, and loved than you'd ever felt in Devildom.
