Obey Me x S/O who has a past like James from Team Rocket

Basically, if you don’t know who he is, his past is that he used to be a VERY rich boy. He had a mansion, servants, etc. But he was never happy with all of it, and even worse, he was destined to marry this woman who was OBSESSED with him. Not the loving type, more like she wanted to marry him for the riches, basically. So one day, he ran away.

Lucifer

• At first, he assumes you left because you were spoiled and wanted freedom.

• Then he hears the full story and immediately revises that opinion.

• He understands what it means to have responsibilities forced upon you.

• The idea that your family cared more about appearances and wealth than your happiness genuinely irritates him.

• He respects the fact that you walked away from unimaginable wealth rather than live a miserable life.

• If you ever doubt your decision, he’ll remind you that freedom has value beyond money.

• The obsessive fiancée especially concerns him.

• He’d quietly investigate whether your ex-fiancée could still pose a threat to you.

• If someone mocks you for “throwing everything away,” Lucifer shuts that conversation down immediately.

• Secretly, he’s proud that you had the courage to choose your own future when so many people never do.

Mammon

• His first reaction is absolute disbelief.

- “YA LEFT ALL THAT MONEY BEHIND?!”

• He spends about three days trying to process it.

• Eventually he realizes how miserable you must have been.

• The more you describe your old life, the less jealous he becomes.

• He gets weirdly protective when hearing about your fiancée.

- “Nah, that’s creepy. Real creepy.”

• He loves that you chose happiness over status.

• If your family ever tried to buy you back into their lifestyle, Mammon would be offended on your behalf.

• Deep down, he appreciates that you love people for who they are, not for what they own.

Leviathan

• Immediately compares your life to the tragic rich-kid characters from various games and anime.

• The forced marriage sounds like the setup for a bad visual novel route.

• He’s shocked you actually escaped.

• Honestly thinks that took protagonist-level courage.

• Understands feeling trapped by expectations and social pressure.

• He’d spend hours listening to stories about your old mansion.

• Then become horrified when he learns how lonely you actually were.

• The obsessive fiancée gives him villain-character vibes.

• He’d joke about them being a secret final boss.

• Secretly thinks your decision to run away was incredibly cool.

Satan

• He sees your situation for what it was: a gilded cage.

• Wealth means very little to him if it comes at the cost of personal freedom.

• The forced engagement immediately puts him in a bad mood.

• Nobody should be treated like property.

• He asks thoughtful questions about your childhood.

• Not because he’s nosy, but because he wants to understand.

• He notices the emotional scars hidden beneath your jokes.

• If your family ever contacted you again, Satan would help you establish boundaries.

• He supports your independence completely.

• He admires that you chose uncertainty over a guaranteed miserable future.

Asmodeus

• Gasps dramatically at every detail.

- “Wait, wait, wait. They expected you to marry THAT person?”

• Immediately declares your former fiancée a nightmare.

• He understands unwanted attention better than most.

• The fact that someone viewed you as a prize rather than a person upsets him.

• Asmo makes a point of reminding you that you’re valued for who you are.

• Loves hearing stories about the fancy clothes and parties from your old life.

• Hates hearing about the loneliness.

• If he ever met your ex-fiancée, he’d absolutely destroy her with polite and passive aggressive insults.

• Constantly reassures you that your current life suits you far better.

Beelzebub

• He doesn’t care much about the wealth part.

• What matters to him is whether you were happy.

• Once he realizes you weren’t, the money becomes irrelevant.

• He’s saddened by the idea of you feeling alone despite being surrounded by servants and luxury.

• The forced marriage makes him frown immediately.

• Nobody should be forced into that.

• Beel becomes one of your biggest emotional supports.

• If talking about your past makes you upset, he’ll sit with you quietly until you feel better.

• He admires your strength more than your former status.

• To him, the fact that you escaped and built a new life is what truly matters.

Belphegor

• At first he assumes rich-kid problems can’t be that serious.

• Then he hears the details.

• His attitude changes surprisingly fast.

• He understands what it’s like to have your future decided for you.

• The idea of constantly being watched and controlled sounds exhausting to him.

• He finds it ironic that people envied a life you wanted desperately to escape.

• Sometimes he’ll ask about your old mansion out of curiosity.

• Mostly because he’s imagining all the places he’d take naps.

• If your family ever tried to drag you back, Belphie would become stubbornly protective.

• He’d remind you that your life belongs to you now, not to anyone else.

WAZUP. HERE IT IS. AND I WENT OVERBOARD WITH over 5 K words!!

Important Note: English is not my first language. Since I am very sick atm, I used DeepL as a translation aid. In my other fics, I write without any AI (only as a tutor to find a fitting translation, since I have no beta in my first language), but here I just wanted to have fun writing and sharing.

cock warming (gender neutral)

"quit moving, you're distracting me."

mammon whimpers weakly behind you, his squirming hips coming to a slow, reluctant stop, but his cock still gives a few defiant twitches where it's buried to the hilt inside you. his fingers curl around your hips, pressing into soft flesh just shy of hurting before he lets go with a long, dramatic sigh. kinda like the sound a dog makes when it plops its cute little head down and lets out a loud breath through it's nose, like it's life is sooo hard. the mental comparison makes you smile, and you focus on your homework with a hum of amusement.

only for mammon's hips to jerk upward again after only a minute, bouncing you in his lap and sending a warm pulse of pleasure through your spine. your fingers curl around the edge of your desk to keep your balance, and you don't even have to turn to look at him before mammon's babbling out his apology. "'m sorry! i can't.. can't help it, ya feel so good," he stammers, voice cracked around the edges as he tilts forward to press his chest flush against your back, "im trying to be good! im tryin, please don't go.. ill be so good." his breath is warm against the nape of your neck, goosebumps raising along your skin, and you lose the motivation to scold him when he starts pressing sweety, apologetic kisses over the curve of your shoulder and the side of your head.

really, you knew mammon wouldn't be able to sit still longer than five seconds like this. he could barely sit through foreplay without getting antsy, so cock warming? he was destined to fail, but you kinda liked scolding him and watching his eyes get all big when he realized he wasn't being good. you can't be mean to him forever though. setting your pencil down with a quiet breath of defeat, you lean back into his chest and tilt your head to look at him over your shoulder. there they are, those wide eyes staring right back at you, glossy with tears of frustration at being teased and made to sit still. awhhh. you lift your hand and gently tap his cheek twice, and he leans in immediately to rub his face into your palm affectionately. "yer done with your homework? can i..?" he trails off, waiting, cheek smushed against the heel of your palm as he blinks at you.

you make him wait a second, two. three rapid blinks follow second four, and when you get to ten he's nearly vibrating with tension. then, you grab the arm rests of your desk chair, using them for leverage as you lift yourself up an inch and drop back down into his lap. you don't know which one of you gasps, but you know the loud whine of relief belongs to mammon. "go ahead, monnie."

you've barely got the first syllable of his name off your tongue before he's got his hands on your hips, hauling you up with all that demon strength hidden behind a lean build, and then yanking you back down with enough force to make you squeak. fingers curled around the arm rests for stability now, you can't do much else but bite your lip and curl your toes in your socks as mammon bounces you on his lap Iike it's nothing. the chair creaks underneath the sudden increase in movement, but it's drowned out by mammon's stuttered moans and the wet noise each drop back down into his lap produces. you don't ride him often, mammon loves missionary because he gets to kiss you without having to slow down the pace, but this postion lets him reach so deep, you feel like he's filling up every inch inside you.

"feel so good, baby.. soo good, don't tease me like that ever again," he rambles behind you, voice squeaky and breathless, and you nod along in agreement without meaning it. you're gonna tease him for the rest of your life, and he'll whine about it but still try his best to be a good boy.

short and sweet cause it's been.... nearly a month since my last fic, and i needed a quick hit to cure my mammon withdrawal

Summoning Sigil

So I used to play a lot of Obey Me back in the day and you know how when you make a contract with any of the brothers you have a summoning Sigil tattoo thingy on your body? Yeah, imagine that but with Mammon! You two make a binding contract for some reason and now you have the ability to summon him whenever you want + a cool new tattoo!

MURI OUT

[melodiesz]

Mammon was a major tsundere, everyone knew that.

Shaking his head and dismissing you when you told him words of affection, ruining romantic moments by getting nervous and muttering something about stupid humans instead of saying how he really feels.

Spouting insults that never held any real bite, leaving gifts at your door rather than giving them to you directly and insisting that he didn’t get it for you, he just had an extra — as if he didn’t eye you down the next day to see if you were wearing the jeweled necklace that took him months to save for.

All for what? To hide his feelings? He wanted you to know he loved you, wanted to be your one and only, but he was scared. Scared you wouldn't love him back. Scared it would ruin your friendship, that he would never get to see the smile he saw when he closed his eyes ever again.

So now, sitting with you in his arms, a pool of blood around you as your breaths stopped coming, he realized it.

He should’ve told you he loved you.

Sincere Requests

Mammon X Reader

Your thumb traced the slope of his nose. 

“What? Dirt on my face?” Mammon asked, eyes crossing in an attempt to get a look at what was the reason for your touch. 

“Yeah. You're always filthy.” You smiled, pinching the bridge of it, right below where his sunglasses often sat.

“Ow. Watch it!” He growled weakly, huffing but not pulling away. As if he even could.

You merely tilted your head, smiling crookedly, a turn of your mouth. “No.”

“This is so unfair.” He complained, sounding nasal because of the clamp of your fingers.

It only made your amusement grow. “It isn't. You're just a crybaby.”

As if proving you right, he whined lamely, rocking in place, his arms tightly pressed against his sides. “Noo…You're just a bully…”

“You know, I've never asked you this…” You stepped back, admiring the sight of Mammon hanging from the ceiling, thick rope wrapped around his torso in a strict embrace. “Doesn't your blood go to your head when Lucifer leaves you like this?”

You watched him spin on the spot, just barely, the way a spider dangles from its web, casual by now, used to it. He tried to shrug, but then again, the restraints were snug to his frame. “Eh. I can take it. Demons are built out of more resilient stuff than frail little humans.”

You arched a brow, unimpressed. “Hm. That's funny. Is that why you beg me to help you down every time? Cause I'm so small and meager?”

Your hand gave his hanging form a quick tug, making Mammon twirl uncomfortably like a spinning top. He groaned loudly, squirming further. “Hey! No! Yer just as bad as Lucifer!”

Your mouth spread into a little grin, imagining he was dizzy by now, or at least a bit woozy. The circulatory system of a demon was a mystery to you, but you figured it must be somehow similar to a human’s. “I wouldn't go through all the trouble of doing this to you. But that doesn't mean I don't enjoy this.”

Mammon whined, lip jutting out defeatedly. “You wouldn't even tie me up? You'd just torment me like a cat with a mouse? I'm no mouse!” He protested, eyes narrowed into deep blue slits. But his discontent never felt like anything beyond the complaints of an ill-mannered child. You offered a quick pinch to his cheek.

“Then stop squeaking like one…” You retorted fondly, sitting back near him, brushing some hair away from his face. A soft chuckle left your lips as you were reminded of a movie series from the human world. A trilogy of superhero flicks. “Do you you know who Manspider is, Mammon?”

He looked up (or down?) at you with curiosity. “Mm. That weird guy from the movies that shoots stringy goo like spiders?” You huffed at his description. He made it sound so much lamer than it really was... 

“Sure. If you want to put it that way.” One of your hands slipped into his hair, scratching at his hair. The reaction was immediate, his gaze shutting quickly, face relaxing into a blissful expression. “There's this famous scene, where he's suspended upside down using his powers, and him and the girl he's into have an iconic kissing scene…”

Mammon's eyes flicked open as soon as kisses were mentioned, that previous curiosity now intensified. “Uh, and like…is it steamy?” 

You roll your eyes but there's some concession in them. “Many people consider it steamy, yes.”

It wasn't hard to work out how the gears had started to turn inside Mammon's head. He was always quick to orchestrate situations in his favor, after all. He tried to suppress a little smile. “You could show the Great Mammon…You know. Sharing your human culture, an’ all that…”

You pretended to think about it, brushing a couple of fingers against your chin. Your free hand still toyed with Mammon's surprisingly soft hair. “I don't know…you've been a real pain lately.”

He struggled against the rope, grunting softly. “Let me down and show me!” Mammon insisted willfully.

You only laughed, steadying him with a palm against his chest. “If I were to untie you, I couldn't show you. You gotta be in this position…”

The insolent demon made another disgruntled noise, glaring at you through his white lashes. The path of his pupils quickly making its way towards your mouth. “Well, I don't care. Gimme some, then!”

“Some what?” You played dumb, stroking his cheek, which only calmed his eagerness momentarily. His warm, tan skin tingled under the pads of your fingers.

“Um. You know…kisses. Kissing.” He mumbled, his cheek turned towards your touch, as usual. “Give the Great Mammon some sugar.” He finished lamely, shooting you a toothy grin.

You huffed, shaking your head. He was incorrigible. “Is your blood pressure dropping? Do you need something sweet?”

Teasing him was one of your many daily tasks. A neverending one at that, since he gave you reason to restart it every couple of hours. Each lingering look and declaration of grandeur seemed to renew your desire to knock him down a peg. Or two. Or three.

Still, it was hard not to indulge on the soft spot you tried so hard to hide. Even harder was abstaining from rewarding his good behavior. Like when he admitted some wrong doing or showed sincerity…

He coughed unceremoniously, clearly trying to get your attention again. In that, he succeeded, as your eyes flicked back to the present. “I'd like that kiss you were talking about…” He cleared his throat, gaze adverted. “Please.”

The last word was said so softly that you could've dismissed it as a draft casting a window open, or Beel rummaging through the kitchen. But no. Your eyes had read his lips in time. And your own accommodated a smile in turn.

“Hm? Did you just say please?” Your fingers busied themselves, playing with the rough rope that kept him in place while your eyes coyly met his. Not only coy, they even seemed a little proud.

Mammon whined, already wanting to take the words back. But when he registered the encouragement behind your teasing, he stopped his weak wailing. “Uh. Perhaps. Don't get used to it.”

After talking, he gave an interested look your way, which he tried to conceal as a casual glance, with no success. Your gaze hadn't faltered. “I like it when you're polite like that. It's attractive.”

His eyebrows raised up so high that they got lost under his messy hair. Mammon blinked in surprise, feeling an extra dose of blood blooming under his skin. “Y-yeah?”

“Mhm. It makes you seem so serious and…manly.” You lied, biting back a trifling smile as you thought about how gullible and cute he was. Although the idea of finding him endearing still unsettled you a bit.

“I am! I super, totally am!” He shook in place as he exclaimed and insisted on it loudly, trying to break from his restraints again. His eyes were bright and eager. “I can show you! I'm very polite. The politest of them all!"

“Really, Mammon? If you asked for things nicely, I think you'd get what you want more often.”

He seemed to consider that, those rusty gears hard at work again. “So, if I just say please…”

“Well, it won't always work. Especially if it's about money. But it might work with…other matters.” You chose to keep it vague, just in case he was inclined to immediately run up to his brothers asking for a new loan.

You could already imagine the disapproving stares afterwards if Mammon were to tell them you gave him the idea.

“Will it work on you?” He inquired, quieter than before. In response, you gave him a non-committal hum.

“Maybe.”

“Please…the Manspider kiss. Please show me…” He begged softly, his lip curling down into a small frown. It made you soften, much to your dismay. You poked the corner of his mouth with your index finger.

“So silly. But you are being nice.” Your frame slotted up slightly, aligning your face at the same height as his. Your hands curled around his shoulders, so he wouldn't dangle around. “Are you sure?”

“Yeah.” He rasped out. His head and chest were pounding, probably thanks to his punishment, but Mammon knew deep down the galloping in his chest had really started for other reasons.

You didn't dare drag it out any longer, and in the blink of an eye, his lips were pressed against yours in a soft, languid kiss. Your mouth moved slowly, capturing his own between subtle sighs.

His kiss, on the other hand, was more hurried. It was as if he were fighting some sense of composure just like he had fought against his bound state. He moaned quietly, eyes fluttering as you softly sucked on his lower lip.

When he tried to deepen the kiss further, you pulled away. You were still in the main hall, after all. If Lucifer had strung Mammon up in his own room, there's no telling what might have happened, but the public nature of the kiss had you cutting it short.

Mammon frowned deeply, the most genuine show of discontent until then. He seemed actually upset, perhaps worried he had done something wrong. “Why'd you stop? I asked nice like you said…”

“Someone might see. And you're on time out, remember?” You murmured, sneaking in a quick nuzzle and kiss to his cheek, which caused him to pipe down, nuzzling back as best as he could.

“Mm. Feels nice, though. I wish we could keep going…” He lamented longingly, eyes half-lidded, disposition sweet. “That Manspider definitely knew his stuff.”

“I'm just glad to be of service educating you on human culture.” You chimed aloofly.

“But I have so many doubts left. I need more lessons! I need private ones! And tests, and punishments!” He began, eyes squeezed shut as his tone got louder. So loud, in fact, that he didn't notice a set of steady footsteps approaching down the hallway.

Lucifer's head quirked to the side, his deep voice cutting off Mammon's speech as he settled beside you, standing tall. “Private lessons? Tests?”

His deep red eyes settled on you, pleasantly surprised but also skeptical. “Good job on him. We might be finally inculcating some discipline into that thick skull.”

Mammon's mouth clamped shut, his face blanching. He gave you a long-suffering stare before directing it at his older brother. “Yes. I'm being good right now. Nothing else is going on. It's just that good, human influence running through my veins.”

Lucifer's doubt became palpable as a result of Mammon's suspicious words. That is before he decided to give him some grace, narrowing his eyes at him but ultimately continuing his path towards the library.

Mammon's shoulders mirrored your own, dropping in relief as you were left alone after some scrutinization. “Could've gone worse.” You whispered. 

“I dunno about that. Now Lucifer thinks I'm a goody-two-shoes who wants to stay up all night with his nose buried in some book.” He spat, face pinched in irritation. If his arms had been free to move, you imagined they would've crossed over his chest.

“No. He must've thought I put a curse on you or something.” Your plush mouth brushed against his temple fondly.

He giggled, before trying to disguise the sound with a grumble. “You would do somethin’ like that to poor ol' me…"

“Only when deserved. So, most of the time, yes.” Another kiss to his cheek. A wobbly smile from him.

“I could get used to some forms of punishment…” He said dazedly, soft enough that an untrained ear would miss it.

Good thing yours were expertly tuned.

Mammon x bookworm GN!reader drabble :0

Reading isn't really one of Mammon's hobbies, but it is one of yours. He knows because he'll have to fight with a book (Of all things! he complains) for your attention during nights in when your fingers stop combing his hair, or even pull a little too hard in shock at the words on the page.

He pouts and whines about how you should be paying attention to him, your boyfriend, and you just softly laugh. Tilting your head, you ask, "Do you want me to read one to you? I got a new one yesterday we could start together."

Mammon agrees with a huff—he'll take what he can get. But then he quickly figures out he actually really likes your voice when you read out loud to him. He gets more invested in the story than you, and when you end the session on a cliffhanger he tells you you're doing this again tomorrow because you're real mean for not letting him find out what happens next.

It becomes regular to the point that he prepares a glass of water for when your throat gets dry, and he's thinking about it during class when he should be doing his assigned readings instead. Mammon can't even try reenacting Satan's reaction when he found out his brother knew the plot to the book you mentioned a week ago—through being mildly spoiled, mind you.

A couple weeks in, one night while you're taking a break for your voice, Mammon does something new: he offers to read to you instead.

You blink at him. "Wait, really?"

"Why’re ya so surprised?!" He huffs and takes the book from your lap before you can say anything else.

He's not used to it; he stumbles over his words and his throat gets dry faster than yours does. But he doesn't regret it—not when you gasp and grab him at the plot twist, or when you whine and laugh when he refuses to keep going until you give him a kiss as payment.

"Payment? I was reading for free the whole time, Mammon!"

"Okay, well, as a reward then! For goin' outta my comfort zone for ya!"

He's joking, sort of, not really. But the book almost hits the floor when you take his face in your hands and kiss him, making Mammon yelp.

"There, now keep going before I take my book back and kick you out," you threaten emptily.

Half-dazed, Mammon fumbles to find where he was, stuttering, eyes and brain not processing what he's saying as he keeps reading. But he thinks maybe books are a good hobby to pick up if it means more time spent with you like this.
