It was a gloomy day down in the Devildom, just one of those days where tensions were high in the House of Lamentation. You were in your room, having just completed your homework so you began studying for a test coming up in the next few days. You had a good feeling you were going to ace it, so you began to organize your books and papers and stash them away in your bag.
You were tired. You had felt overworked as of late, always having work to do, or having one of the brothers drag you into one of their troubles as usual. But today? Nobody had reached out. Everyone had seemed so distant from one another. That wasn’t normal, it was always loud in the house no matter where you went. The fact that it was so quiet for once was shocking.
You finished packing up your school supplies and leaned your backpack against your desk in your room. You just wanted to relax, so you decided to ease your chest and arms comfortably onto your desk and scroll through Devilgram for a while. Looking through the brothers’ profiles always put a smile on your face, because they sometimes posted the most hilarious pictures. However, you found yourself on Mammon’s profile for the longest.
He was a model, of course he was stunning. Perfectly-tanned skin, luscious snow white locks gracing his head, the most beautiful blue eyes that almost glowed gold. You could never tell him how you really felt, he would just push you away. Plus, there was probably some model out there who was after him already anyways. Why would Mammon want to be with some weak human?
You jumped slightly as a text notification popped up on your screen.
“Dinner is ready, please make your way to the dining hall. You wouldn’t want Beel to get to your plate first,” Lucifer sent. You chuckled and began to make your way down to have dinner. Hopefully, it wouldn’t be as awkward as it was earlier that day.
You make it down to the dining hall, not a single of the brothers making eye contact with you. You froze in your tracks. You can’t lie, that hurt a little bit, you figured at least one of them might greet you.
♡
“Good to see you, Y/N. Come, take a seat. I know you have been working hard up there, you need to eat well,” Lucifer stated, a slight smile on his face. He was glad that at least one of you was focused on your studies that day.
You smiled, finally someone broke the awkward silence. “Thank you Lucifer.”
You made your way around the long table to find an open seat. Your heart fluttered as you walked your way past Mammon, smelling the arousing scent of his cologne waft past your face. You smiled and let out a low but happy sigh, and he looked up for just a second having heard you, a light blush on his face. “Y’know I don’t bite, you can come sit next to me human,” Mammon said lightly, making eye contact with you for the first time that day.
You felt a shudder run down your spine. His voice is so alluring, you could listen to it all day every day. A blush forms on your cheeks as you take a seat next to him.
Everyone around you is surprisingly in their own conversations with one another, which is pretty odd after earlier. Although, you were happy to hear the voices of all of your favorite people around the room. You couldn’t dare to complain, it was nice seeing everyone let go of the awkward tension that had previously filled the House of Lamentation. This, however, was short-lived.
You were almost done with your dinner, only a few forkfuls left, when you heard an argument start. “Oh great, here we go again,” you thought to yourself as you looked up to see Lucifer standing up behind Mammon. You didn’t have a good feeling about this.
“You worthless scumbag, what did you do with my new Ruri-chan figure?!” Levi yelled, close enough to Mammon’s face to spit on him whilst speaking.
“My new perfume went missing too, I bet it had something to do with that idiot,” Asmo shouted across the table at him, a sour glare on his face.
“Come to think of it, my new mystery novel went missing last night, I was going to read it but I couldn’t find it,” Satan added to the fire.
The twins began to spew on about how much of a moron Mammon was, him having done nothing to either of them. Lucifer began to holler at Mammon about every little thing he finds wrong when you realize that was the last straw. You weren’t going to sit there and let everyone torment the demon that meant most to you. You looked over at Mammon, trembling in his seat, trying to hold back tears as his brothers kept pushing him further and further over the edge. He looked like he could break at any second. You know for a fact he didn’t take anyone’s things, he was with you all day yesterday. It couldn’t have been him.
“KNOCK IT OFF, ALL OF YOU! BACK OFF! I THINK HE’S HAD ENOUGH ALREADY!” you shouted at the top of your lungs. The boys all froze in shock and fear, never expecting that out of you. Tears began to stream down your face. You never thought you would see the day that you would have to break up an argument, especially when the only people Mammon trusted were his brothers. Seeing them all treat him like shit made you angry and upset.
“Y/N...” Lucifer sighed and began to speak, but you weren’t going to give him the chance to continue.
“C’mon Mammon, you don’t deserve this, let’s get out of here,” you gently took hold of Mammon’s hand and dragged him away from the table towards his bedroom. The dining hall fell completely silent once again.
♡
You make it all the way to Mammon’s bedroom door when he stops you in your tracks, pulling your arm back towards him lightly. You turn around to see his cheeks burning red, the tears that formed earlier finally starting to come down his face. He looked somewhat relieved, somewhat embarrassed at the same time. He just barely lifted his head to look you in the eyes.
“You didn’t have to go and do that for me human, ya know I can’t handle m’self, right? I-I just needed to think of what t’say...” he said softly, not enough confidence in his voice for you to believe it for a second.
He was shaking, more so than when he usually gets yelled at. You gently let go of his hand and lifted your hand to cup his right cheek, brushing away his tears with your thumb. He felt so warm.
“Mammoney, I wasn’t just going to sit there and let them stomp all over you like that. They have NO evidence to prove that you took anything from them, but they kept going anyway. I’m so sick of their bullshit, watch them find all of their things that they misplaced themselves. I hope they hate themselves for treating you like that.” You loosened your hand from his cheek and tucked your body against his, arms wrapped around his warm shoulders, bringing him in for a cozy embrace.
This broke him. He leaned into your embrace, the tears streaming down his face as he sobbed into the crook of your neck. The two of you stood in a hug for at least 2 minutes straight, neither of you daring to break away. It just felt so nice, you never wanted to let go.
“Th-thank you Y/N, I’m glad you trust me enough t’know I wouldn’t steal their boring stuff. Why would I need Asmo’s perfume, let alone Satan’s book? Y’know, I-I wonder if they think before they point f-fingers like that. C’mon human, let’s get inside, I just w-wanna relax.” Mammon explains with the slightest blushy grin on his face. He opens the door to let you in first, and closes it behind him.
You had never been in Mammon’s room before, he’s never let you in before now. Your eyes scanned around the room, in awe of how cozy it was. His plush leather sofa and a mahogany wood pool table beside it, bottles of alcohol and a few grimm strewn across it. He has a projector rather than a television, two speakers beside the coffee table below it. He has an open concept closet, adorned with studio lights, and his bed pressed flush on the other side of the wall. His room has two floors, the only things up there being his entryway door... and a car? How did he get this in here? What kind of car was it? How interesting. Rather than walking down the stairs as Mammon was expecting you to do, you made your way towards his car and leaned against the hood.
“Is this your car? It’s so amazing! I can’t imagine how much money you must have put into this beauty,” you exclaimed, being somewhat an admirer of cars, having been raised by your father who’s life revolves around them. You grazed your hand over the headlights and the grill along the front, a glint in your eyes from the spotlights shining down on you and the car.
Mammon was standing next to the door, choked up to say the very least. He was blushing furiously, gripping into his lush white hair with his hand, head tilted down and giggling. “Y’mean my Demonia? It’s nothing really, Lucifer helped me get it a while back once I got my license. Pretty cool right? Of course the Great Mammon is cool!” he chuckled, barely able to keep eye contact with you. The truth was, the car meant a lot to him and it did cost a lot, but he couldn’t focus on that right now. He was too busy staring you down, lights glistening against your soft skin, looking oh-so-hot leaned up against his car like that. Little did you know you were his treasure, he admired you every second he got, whether you realized it or not. He began to walk over to you, leaning next to you on the hood, resting his hand softly against yours, interlocking fingers with you.
Needless to say, you were surprised. You jumped slightly at his touch, hesitant to move. You returned the favor regardless, locking your fingers between his, the warmth of his body flushing through your veins, instantly calming you. He means everything to you, and now this? How can you not tell him how you feel now? This was the best opportunity you could get your hands on. You let go of his hand and made your way off of the hood of the car, locked his bedroom door, dimmed his lights slightly, and made your way back over to him. You inched closer to him, barely hugging distance away.
He was looking up at you softly, still blushing. He was shaking a little bit, but you were too, of course. Now was your chance. It was now or never. Either you tell him how you feel now, or hold it in and never find out if your feelings are reciprocated. Your heart was ready to burst out of your chest, but you couldn’t hold back any longer.
♡
“Mammon, you know I care about you... more than myself sometimes, if I’m being honest. Any time I see you enter the room or my eyes meet up with you, I get tons of butterflies inside. You make me feel like I’m not just some useless human that nobody likes. You make me feel special, and I just want you to know that... I love you. I’m in love with you...” you paused, too nervous to continue.
Mammon.exe has stopped working. You... love HIM? The moron, the idiot, the scumbag? You deserve better, but he can’t deny how he really feels. His brothers aren’t anywhere around, so now’s his chance.
“I-human I... I love you too. Y’mean everything to me. I can’t stand seeing my brothers eyeing you up and taking all of my time with ya away from me. You’re MY human... my... my treasure. You deserve better than me, I’m just some lousy good-for-nothi-” he couldn’t speak anymore. You held him by his cheeks and pulled his face to yours, kissing him on his lips. The first tender moment shared between the two of you, your first kiss. He sits still for a moment before realizing what’s happening, leaning into your kiss and holding you by your waist. Your chests graze against one another as the kiss turns more passionate. Mammon slides his tongue against your lips asking for permission before you slide your tongue in between his. You felt higher than a kite at that moment, the butterflies seemingly flying out through the top of your head.
Before long, you were straddling his lap on the hood of his car, breathing into his neck as he planted kisses along your collarbone, nibbling at you and caressing your lower back. You both pulled away from each other to look into each others’ eyes.
“So this is really happening huh?” you blush and look down, feeling a tad bit shy. Mammon brings his hand up to your cheek, some of his fingers lacing into your hair. “We don’t have to do anything ya don’t wanna do, but first...” he places his hands lovingly on your hips and looks into your eyes. “I want you to be mine and only mine, ya hear? No mackin’ on my brothers or anythin’... you’re MY treasure. Well, if you’ll let me have ya...” he starts blushing too, barely able to keep his eyes on you. The words you have been waiting to hear, that you’re HIS and only his... it makes you melt. You hold onto his hips, and lean in to whisper into his ear. “Of course I’m yours, and only yours. You can have all of me if you want it, and I mean ALL of me...” you whisper and nibble on his earlobe, a smirk forming across your face.
He can’t hold back anymore. He slams his mouth against yours in the most passionate kiss, moaning against your lips and pulling you in closer, pressing you against his chest. His hands start to slip under your shirt, making their way up your bare back until he reaches about midway. He looks at you as if he’s asking permission, to which you respond by grazing your hands over his upper thighs. You lean in once again to whisper sensually, “So have you ever done it in your car?”
♡
His excitement cannot be contained, his body heats up hotter as the bulge in his pants grows harder. Without another word, Mammon scoots off of the car, grabbing you underneath your thighs and carrying you into the backseat of his car, placing you gently while he pushes the seats back and reclining them back further. The open space has grown larger. He climbs his way into the car and shuts the door behind him, hovering over you.
He doesn’t waste any time before he starts to undress you. He slips your uniform jacket off followed by your tank top, revealing your black lace bralette. You whisper in his ear “You like that? I bet you’ll like it more when you see the panties I have to match.”
You set off a fire in his chest, a low growl seeping out from his throat. He sheds his uniform jacket and tears off his undershirt, a huge ripping noise emerging, making you increasingly wet as the tension increases. His bare chest is a glorious sight to behold... so sexy and strong, so protective.
He pushes you back against the seat and makes room to slide off your uniform pants, whilst you slide your shoes off and kick them into the passenger seat beside you. He makes his way down to your feet, carefully sliding off your socks which he notices have a grimm pattern on them, and slyly smirks. His eyes scan your exposed skin from your head to your toes and back up, revving him up even more.
♡
He begins to kiss you from your feet, up your calves and your thighs, until he reaches your inner thighs. Your black lace panties meet his face, becoming more and more flushed. He slides his hands up to the waistband and toys with the lace, planting his face against the fabric. That smell... the smell of arousal... it’s so strong. He could only imagine how wet you are for him. He looks up at you and you nod, giving permission to continue.
Mammon growls and grabs your waistband with his teeth, the sound of tearing lace floods the car. You moan in response, wishing you could hear him like this all the time. Your hands reach down to your now exposed heat and stroke the lips, shining from how slick he made you. Mammon’s eyes start shining, staring down as if he’s a predator who’s just hunted down his prey. He licks his lips and flashes his teeth, slight fangs showing. You spread your lips for him and make your legs more comfortable, inviting him to take a taste.
“Mn... you’re so perfect Y/N, so wet for me, I can almost taste it,” he leans down and begins lapping his tongue at your clit. Shudders run up and down your spine from the senastion, bringing out a sensual moan from your chest, back arching. Mammon grips onto your thighs and holds them open. He drags his tongue up and down your opening, sliding it inside of you. He moans into you, admiring how you taste, your flavor. He makes his way back up to your clit, the tip of his tongue dancing around it. He looks up and you and smirks, sliding two fingers inside of you, pulsing them in and out at a steady pace, curling his fingertips from time to time. You can’t help but let out a moan, never having felt so stimulated and so turned-on before.
“M-Mammon... p-p-please... k-keep going b-baby...” you moaned out as he brought you closer and closer to your orgasm. Did you just call him your baby? Oh, he heard that. He wants to hear it again. He pulses his fingers inside you faster and faster, sucking on your clit, giving you no mercy. The heat inside of you is unbearable. You begin to buck your hips against his face and grab him by the hair, pushing him against your heat, your other hand gripping tightly against the leather seat below you,
It was taking everything Mammon had to not whip himself out and slam himself into you, but he had to make himself more comfortable. As he continued, he used his left hand to undo his pants, releasing his bulge hidden by his boxers. He was only getting harder as you moaned his name again and again.
“I’m... I’m gonna.. gaaaAAAHH!” you moaned out as you reached your orgasm, letting your grip loose from his hair as your body let go of the tension. Mammon laps his tongue down to clean up the mess you made. He gathers some on his tongue, looking up to you with his tongue sticking out, when he suddenly takes it into his mouth and swallows you.
He notices the flaming blush that adorns your cheeks. He brings himself up, sitting on your thighs, his bulge prominent. You stare down his body, glazed in sweat, realizing he lapsed into his demon form as you came down from your orgasm. His horns were shining, wings folded against his back as the car wasn’t a big enough space to let them free. You were positioned on the driver’s side back passenger’s seat, so you decided to slide into the center seat. You reach your hands to touch Mammon’s back, stroking his wings ever so gently. He moans in response, realizing he’s sensitive there. You begin to help guide them open as he leans into you. They fly open and block the whole view out of the windshield, darkening the space between you.
♡
Your hands come down to meet his waistband, tugging on it carefully. You look up into Mammon’s eyes, he can see the desire written over your face. He makes his bulge dance in response, prompting you to go for it. You drag down his boxers and out springs his length, glistening from his precum. It looks so tasty. You lean back in your seat to where you are practically laying down, gripping behind his thighs and urging him to come forward. He was on his knees, his length shadowing over your chest, his tip just barely against your lips. You hold yourself up by your elbows, turning up to him, teasing him “I bet you want your cock in my mouth, don’t you Mammon? You want to see your fragile human squirm under you, taking all of you inside of them?”
Oh, you did it now. His claws getting ever so longer as a growl comes from deep in his chest. “If you want it, show me just how badly,” your last words as he gripped your hair and pushed your mouth around his length, letting out a choke. He moaned in pleasure as he felt himself at the back of your throat, vibrations coming from you barely fitting him inside you. Mammon begins thrusting his hips back and forth, you sucking up on his length oh-so-perfectly. The smell of arousal and the sound of moans fill the car, enveloping both of you. All either of you can feel is bliss. He breaks the silence.
“Y-Y/N... y-you’re so warm, ya s-suck me off so well, k-keep going, I’m getting close-” He can’t speak anymore, feeling the surge of pleasure rush up through his thighs as you swirl your tongue around him, bringing him to the edge. You pull your mouth off of his length and put his hand around it, urging him to get himself off. “I would love if the Great Mammon would cum for me, I want to feel it all over my face, I want you to make me yours, show me who owns me,” you moan up at him, pulling down your bra to release your warm breasts, toying with them to tease him.
“Oh f-fuck, y-you’re all mine, my treasure, my b-baby, I’m.. I’m...” he groans out, and he’s pushed over the edge. He bucks forward, letting out a deep deep growl, moaning your name and climaxing all over your face and your chest, his cum hot against your skin. He looks down at you taking his load and lets out another groan, watching as you lap it up with your fingertips, eventually licking them clean.
♡
He pushes you down against the leather seats, his length rubbing against your throbbing heat, aching for you. You let out a squeal from your sensitivity, your chest arching up towards him. You reach your hands down to try to push him into you but he stops you, grabbing your wrists and pinning them down above your head. He pushes his lips firmly against yours, exploring your mouth with his tongue. Your chests are touching, he’s just about burning you with the heat radiating from his body.
He pulls away from your face and looks down to you, it looks like he wants to say something. He looks... nervous? After all of that?
“Mammon, are you okay?” you asked gently, turning your head slightly, a smile on your face. “Y-yeah, I just don’t wanna hurt ya. I tried to open ya up for me but what if it’s too much for your human body to handle?” he sighs and stares away for a moment. He loosens the grip on your wrists and you cup both of his cheeks, whispering up at him softly, “I trust you with my life, Mammon. I feel so safe with you, you’re my protector. The Great Mammon. I promise if it’s too much I’ll tell you right away. It’s okay baby.”
He nods and smiles with a blush in response, he couldn’t be happier to hear you say those words to him, as unexpected as they are.
You spread open your legs for him, situating your body in a more comfortable spot, preparing for the time of your life. You lift yourself up with your hands and whisper into his ear, “Take me for a ride, won’t you?”
♡
He growls and stretches his arms and his back, preparing himself. You want a ride? A ride is what you’re gonna get, and it’s gonna be a bumpy one.
He picks up your bottom half by your thighs, dragging you towards him, putting you in the perfect position. He takes hold of his length and lines himself up with your opening, rubbing his tip up and down your heat. You squirm under him, pleading with him in your head, dying for him to give you what you’ve only dreamed of for nearly a year now. He hears you struggling and lets out a low chuckle, a bit evil. He likes to see you all worked up for him, there’s nothing better, honestly.
He begins sliding his length inside of you, the heat from within immediately making him jolt. He can’t help the arousal from feeling you around him, squeezing him tight. You let out a small whimper and look up to him, concern suddenly written all over his face.
Your wrists had been freed a while ago so you take this opportunity to grab onto his soft bottom, pushing him further into you, moaning right in his ear. It hurts... it hurts so good. He’s so big compared to you. Your eyes roll into the back of your head as he hits the deepest parts of you. You must have awakened something in him, the look in his eyes giving him an almost primal vibe. He leans down and whispers into your ear along with a growl “That’s a good human, take all of me inside of ya, scream my name, ‘m gonna fuck you so hard ya won’t walk for a week...”
He thrusts in and out of you at a fast pace, hitting your core over and over again. You’re both moaning and groaning into each others’ ears. Mammon grips hard onto the headrests of the seats, pounding into you like it’s his last day to live. Your hands grasping at his shoulders, you can’t help but claw your nails down, leaving red scratches all over his back. He almost hisses in response, causing you to moan out louder. He takes his right hand and brings it to your throat, silencing you. Your eyes roll back into your head once again, your back arching and your hands gripping tight against the leather seats, nearly ripping them open.
♡
His thrusts speed up, bringing you closer and closer to the biggest orgasm of your life. Mammon's hand around your throat, you try to let out a sentence, “Mammoney baby, I’m gonna c-cum for you, p-please, d-don’t hold back,” you managed to say. His face goes beat red and wings flutter behind him.
You stroke his horns atop his head, barely letting out one last sentence. “F-fill me up with your cum, m-mark your t-territory, I’m a-all yours-” your sentence is cut off as your orgasm takes over your body, Mammon releasing your throat, you proceeding to scream his name in pleasure as you gripped his length inside of you, trying to juice him.
He pounds his length into you faster and faster, bringing himself to the edge of his climax. He can’t hold back, can’t speak. He brings his head down to bite your neck, leaving teeth marks and a little bit of blood afterwards, marking you as his. He sucks on his marking and groans out loudly in pleasure, unable to contain himself any longer. You can feel his length twitch as he fills you up inside, heating the inner walls of your core, giving you the most butterflies you’ve ever had.
♡
You both look down and giggle along with deep breaths, you did a number to the seats of his car. You look at him in worry as he sees the condition of the leather. He notices that you look scared so he holds you tight to him, body-to-body warmth between you.
“I can already tell what you’re ‘bout to say, and it’s alright. Y’mean more to me than some leather seats. Now I can look at my seats ‘n remember my first time with ya, amirite?” he says with a smile, placing the most gentle of kisses on your lips, glazed with sweat.
You go to try to stand up to get out of the car but your body is beyond it’s limits. Mammon notices you struggling to get up and chuckles. “I told ya you wouldn’t be able t’walk for a while.”
♡
He pulls his boxers back on and picks you up bridal style out of the car seat, carrying you down the stairs and onto his bed gently. He remembers tearing up your underwear so he dashes to his closet, finding one of his favorite t-shirts and a pair of pajama pants and swiftly bringing them over to the bed.
“Put these on, we don’t need ya walking out with stains on your uniform and no underwear,” he explains with a giggle. He looked up at you to see you looking sad. “What’sa matter treasure?”
“Well, I was hoping... maybe... that I could stay with you for the night?” you ask, nervously waiting for a response. Mammon helps you take off your bralette and get dressed in his comfy clothes, and cups your cheek, looking into your eyes.
“Of course y’can stay with me, you’re my human! My treasure! Who wouldn’t wanna stay with the Great Mammon anyway?” he smirks and chuckles, you smacking his chest in return.
He crawls up into the bed with you, laying you next to him and pulling your back into his chest. He covers you both with his bedspread and begins rubbing your arms, resting his cheek against your ear. He had never felt this way before. He really fell for a human. Does he regret it? Not at all, he wouldn’t have it any other way. The only problem now? Now he feels like he has to protect you forever, all the time. He loves you too much to ever see you get hurt.
“S-so... does this mean... y-you’re my girlfriend?” Mammon let out shyly, almost expecting you to say something negative or reject him.
You turn back to face him, your arm around his waist. You smile up at him, “I would love nothing more than to be your girlfriend... your treasure.” You plant the lightest kiss on his forehead and turn back around as he begins to spoon you again. Within the next few minutes, you fell asleep in his arms, not a care in the world, no thoughts besides the thought of being his treasure forever.
♡
The brothers felt bad about what happened earlier and were worried about Mammon’s well-being. Lucifer approached his door with the brothers, quickly realizing it’s locked. He took his master keys out of his coat pocket and unlocked Mammon’s door. He took a few steps in and froze in place. His brothers glanced with him over his shoulder to see Mammon with his arms around you, protecting you, sleeping next to you.
They all couldn’t bring themselves to make a sound. They couldn’t believe their eyes. Y/N... and Mammon?
“It’s about time he told her how he felt!” Asmo shouted as the brothers all shushed him, not wanting to wake the two of you.
“We can talk to him in the morning, let him have peace for once today. I can only imagine Y/N needs rest as well,” Lucifer explained.
Lucifer and the brothers turned around and Lucifer locked the door behind him, a cheeky smirk on his face. He was proud of his brother for finally being honest with himself and taking pride in what he wanted. Would he ever let Mammon know that? Oh, hell no.
♡
I’ve wanted to see a fic about this ever since I fell in love with Mammon and saw his room, so I wrote it!
I’m only comfortable with F!MC writing since I’ve never familiarized myself with GN!MC or M!MC. My apologies!
I do NOT give permission to post this anywhere else. I also have this posted on Wattpad, my username is daradoodlebug. If you like my work, please feel free to like, comment, follow, share, or REBLOG. Thank you for taking the time to read my first piece!
