[Yandere] Mammon ♡

Rating: Mature [MDNI] Tags: dark content, possessiveness, fighting, stalking, implied murder, smut, gn body parts, penetration mentions, cock warming, semi public sex, changed canon events Word Count: 1.4k+ A/N: I love yans and I love Mams soooo...here we are lol. Happy Birthday to my favorite greedy demon ♡ Mammoney!

♡ Yandere Mammon, who has been by your side since the very first day you dropped into the Devildom.

-> He didn't think much of you at first - a mere hassle dropped onto his plate by his Prideful elder brother. But it doesn't take long for the Avatar of Greed to become completely obsessed with you.

-> He actually made Lucifer give him your file ahead of time, wanting to size up how much trouble you'd be and see what kinda wealth you'd be bringing him. When his golden eyes landed on your picture though, a new sense of greed wrapped itself around his heart, and he knew he just had to have you.

♡ Yandere Mammon, who is a hell of a lot smarter than his brothers give him credit for.

-> He's the one that actually planted the seed in Leviathan's mind that you should make a pact with Mammon in the first place. Paying his debt to the Third Born was worth having the chance to cement himself as your first pact mate - which he always uses to his advantage.

-> Any situation you find yourself in, Mammon manipulates his way to get access to you - whether it's his usual antics (like him 'whining' about being your first man), or even some of his more greedy tricks like bribery, you'll always find him right next to you. There are even times he uses the pact to summon himself to you, and convinces you that it was subconsciously your idea because you always need him by your side - 'Ya know I was tasked to protect ya after all, treasure.'

-> On the rare occasion that Mammon can't be with you at the moment, he sends his murder of crows to look after you - especially even when you're with one of his brothers. His feathered familiars keep an eye on you no matter the realm, and they diligently report back to their Master with any findings.

♡ Yandere Mammon, whose greed for you knows no bounds.

-> Whenever you're with one of his brothers, he finds a way to squeeze himself in. He gives them a look of warning - he wouldn't necessarily kill one of his brothers, but they might find themselves befalling serious misfortune if they don't back off from you.

-> He doesn't afford that same luxury to strangers, though. Sure, he may start off with the warning of bad luck, each demon that gets too close to you suddenly finding themselves penniless. But if they still don't get the hint between that and Mammon's death glare, then he'll be sure to follow them home and have a nice chat with them later - just be sure to kiss his bruised and bloody knuckles when he comes home and lies about it.

♡ Yandere Mammon, who wants nothing more than to hoard you to himself like a rare Devildom treasure - because that's what you are to him.

-> He absolutely took Beelzebub's custard on purpose, knowing your room would get demolished in the process. Before Lucifer could make you move into Beel's room however, Mammon spots Satan and ropes him into the scene, knowing he would get triggered by the First Born and escalate the situation worse. Fists get thrown between Pride and Wrath, and Mammon uses the opportunity to steal you away to his room.

-> You pretty much live in his room now - he's replaced your destroyed belongings and given you space in his own closet. You don't notice a few of your things still going missing occasionally - and you definitely don't notice the secret door in the back of his closet, leading to the shrine he's made of you, your missing items adorning the altar.

-> Something else you fail to notice, is how he prolongs the reconstruction of your bedroom. It first started with him just tearing down the current work being done to rebuild it - that is, until he got the idea that if he started picking off the construction demons one by one, it'd surely slow down production. It was quite messy work at first, until he remembered his little brother was the Avatar of Gluttony who has never left a scrap of food behind.

♡ Yandere Mammon, who despite wanting you all for himself, still loves to show you off as 'His' to any and everyone.

-> He may be the Avatar of Greed, but he absolutely loves making people jealous - he wants them to covet what he owns, especially when it comes to you. He buys you revealing outfits that cost a pretty Grimm, just to dress you up and parade you around the city on his arm.

-> His public displays of affection for you are constant - there's not a single being in the Devildom that hasn't seen the way his hands grab your body, the way he presses his lips to your neck. And when he gives you gifts, he makes sure to do it in front of other people, so they can see the way you look at him and kiss him on the lips so lovingly.

♡ Yandere Mammon, who toys with how much luck you have in order to keep himself as close to you as possible.

-> Some days Mammon feels you aren't giving him enough attention, and you suddenly find yourself having the worst luck - bad grades, failed cooking, accidental injuries. And there Mammon is, right there by your side with open arms, ready to care for you like the perfect boyfriend that he is.

-> Other days, Mammon spoils the hell outta you - with all that good luck on your side, you suddenly find that you won a ton of Grimm from some Devilgram contest you don't remember entering, and he's convincing you to go away to the beach for a week, just the two of you.

♡ Yandere Mammon, who infects those around him with greed in order to move along his own hidden agenda.

-> He talks his way into going to your meeting with Lord Diavolo, despite Lucifer also being there. All it took was a little greed and a few well placed words to convince them to give you a permanent citizenship in the Devildom, despite all of their earlier reservations. The elder demons later side eye Mammon, but he just throws his hands up, insisting he couldn't possibly be that powerful and doing his best to hide his smugness.

-> He uses this ability on his brothers as well - usually either on Satan, Asmodeus or Belphegor. Whenever he isn't getting his way, he infects one (or multiple) of them with his greed, standing back with an arm around your shoulder and his signature smirk on his face as he hears his brothers argue with Lucifer for him - his brothers already love you, so they don't think too much about it.

♡ Yandere Mammon, whose obsession with you fills him with an inherent need to mark you as his.

-> He needs everyone to see that you belong to him. It starts off innocently, with him giving you gifts of jewelry and insisting you wear them. Some of the jewelry very obviously brandish his sigil and symbols, but little did you know, the other pieces have secret inscriptions to let other demons know that you're his.

-> And of course he put his pact mark somewhere obvious, in a spot you couldn't hide it. 'Why would ya wanna hide it, anyways?!'

-> He also loves to bite - why wouldn't ya want his adorable fang marks on the side of your neck? He'll take any chance he can get to add another permanent little mark of his on you - without hurting you too much, of course.

♡ Yandere Mammon, whose greed seeps into every fiber of his being as he passionately fucks you into his mattress.

-> You don't miss the way he chants 'Mine' over and over like a prayer as he roughly thrusts into you - the way his rings dig into your flesh as he holds you too tightly through your shared orgasms, silently vowing to never let you go.

-> He pours greed into your pact in order to hear you beg for him - your own avarice causing you to cock warm him even after you've both fallen asleep, so full of his sin you can't stand the thought of separating.

-> Sometimes he's so needy for you that he can't wait until the two of you get home - he'll pull you into a storage closet or an empty classroom and start having his way with you - he doesn't even care if someone hears the two of you, in fact he almost wishes they would. Knowing he's the only one that can have you this way makes him want to pound you against the wall that much harder.

♡ Yandere Mammon, who will stop at nothing to keep you forever.

"Ya don't know just how much ya mean to me, treasure. I'm never lettin' ya go."

September together

Characters: Mammon x gn!reader

Warnings: Gender neutral reader. Mention of pervy thoughts, but no description or details given. Just fluff. Kinda long, sorry!

Summary: September is Mammon's month, but so it's yours. For his birthday, you ask what does he want, and it seems like you two might be on the same page.

[Note 1: The following characters belong to the mobile game "Obey me: shall we date" and are owned by Solmare Corporation. This is a mere work of fan-fiction.

Note 2: GN!Reader - This is one of my first times sharing what I write, so please be kind. English is not my first language, so there might be orthographic and syntax errors. Also, I use italics for thoughts and/or memories. I came up with the idea because my birthday is on September too. I thought it was kind of fun to share the birthday month with my 2D boo].

✨️💛💛💛💛💛💛💛💛💛💛💛💛💛💛💛💛💛✨️

It's late, although it's hard to tell the exact time when looking out the windows: the infinite, eternal darkness of the Devildom is hard to decipher.

Beel and Belphie blow out the candles on their huge cake. One side purple, with beautiful silver star decorations; and the other, red, with small golden suns around it. Two huge candles above, one in the shape of a waning moon and another in the shape of a radiant sun. And the delicious aroma of vanilla, strawberries and chocolate that emanates and fills the dining room.

This time you had given your soul to this huge edible piece. The twins smile blushing: this large cake handmade by you was the best gift they had received in many years.

Beel and Belphie look at each other tenderly, Beel puts his hand on his brother's shoulder and, with a puppy smile, says: "Happy birthday Belphie". Belphie smiles, his facial expression is calm and sleepy, and yet it is full of affection towards his brother: "Happy birthday Beel."

Asmo sighs with a smile, and you know what he's thinking. He confided it to you not long ago: Asmo has always longed for that complicity that the twins share. You look at him for a moment and feel a slight sadness, hidden behind a centuries-old loneliness and trapped between jealousy and happiness for his younger brothers. Your hands leave your pockets and you try to approach him with the intention of pampering him a little, only to be intercepted by Belphie.

Belphie takes your hands in his, looking at them carefully. There are red, purple and blue spots on them. It's from the dye of the cake gloss that you couldn't wash off completely.

- "...your hands..." -says Belphie.

Mammon hides his hands behind his back, pulling at the long sleeve of his jacket, hoping it will cover the stains on his own hands. Mammon isn't exactly the most skilled cook out there, and yet he helped you all afternoon making this enormous cake for his youngest brothers.

Meanwhile, Belphie runs his index finger over the stains on your hands, his touch is gentle and careful, and though it looks innocent, it harbors a deep carnal desire. Though you can't decipher it. Sometimes you're so airheaded about this kind of thing. But Lucifer and Asmodeus do notice, they both realize it and their faces contort, looking at the hidden intentions of their brother, who is yet another rival. A dangerous and stealthy one.

-"You sure worked very hard for us, Y/N."

You smile, answering: -"It wasn't just me, you know? Mamm-"

Suddenly, a hand covers your mouth. Although the movement was quick and unexpected, the contact is gentle. Mammon looks down and meets your gaze, his hand still in your mouth, the other holding your wrist. His touch is so sweet and so serene for a moment full of adrenaline. As if you were a precious crystal that could break at any light touch. His brothers are surprised by his strange outburst.

Except Leviathan.

Levi sighs and slowly looks away, tired of the furtive actions that suddenly arise, out of nowhere, between you and Mammon. They are so hateful: the stolen glances, the way your eyes share long talks in a matter of seconds, the secrets you two tell each other quickly through laughter, the way you two gravitate around each other wherever you are. And then, back home, how your steps synchronize and your gazes meet from time to time between smiles that say so much even though the words don't come out. That tension, which is like now's.

As Mammon looks at you deeply and carefully, you realize that this is another one of those rare times when he does something for his brothers and doesn't want the credit. You don't move and just continue to stare at him. And although there are no words or body movements, Mammon understands that you understand.

Slowly and carefully, he removes his hands from you.

"What was that, Mammon?"- says Satan.

Maybe it's because of how quickly things happened, but it's not until that moment that Belphie sees the stains on Mammon's hands. As Belphie watches, Mammon puts his fists in the pockets of his jacket. He then looks at Satan and responds with a huff, -"Nothing".

"You could have hurt them..." - Satan responds. Is not true. As they argue about how Mammon stopped you, you think that his surprise attacks make your heart beat faster until it threatens to burst out of your chest. And, as their argument continues, you feel a sweet burning in your stomach, and your heart beats faster and faster. Now you can't stop thinking about his hands and how he grabbed your wrist fiercely and placed the other gently on your face. The friction between the palm of his hand and your lips, just a moment ago, the hand of the person you love was in your lips. Soft hands that hold you and touch you gently. You run your index finger over your mouth and think, "Would a kiss from him be this soft?"

Your thoughts are interrupted by Belphie: -“Y/N, when's your birthday?” The discussion stops and everyone looks at you expectantly: -"In September, the day is the..."

Mammon's eyes light up, and his facial expression changes. He is no longer angry with Satan or arguing with his brothers. Suddenly, he feels like he shares something special with you, as if what you already share wasn't enough and that it doesn't make Levi and the others jealous.

"September? It seems like that month we will celebrate twice as much" - Lucifer smiles and looks at you fondly. You've become another person to care for, part of his big family, home.

You smile sweetly, and if you weren't so clueless, you would have noticed that the seven brothers feel as if the air lightens and many flowers appear around you every time you tilt your face, close your eyes and your lips curl up. They love you so much, and you love them too. And yet, their love is not like yours: innocent and serene.

Except for Mammon.

Mammon is the person you love the most and who you seek the most. You share your daily life with him and pray that he doesn't notice your feelings because what would happen if he finds out and then your friendship can't continue? And yet, you can't hide how much you adore him.

Mammon is usually a living contradiction: how can someone be so wonderful and so careless at the same time? How can someone be so kind and so selfish at the same time? How can someone be so generous and so greedy at the same time? Mammon is a demon, and yet he behaves like an angel towards you.

Your gaze falls on each of the seven faces in front of you, but it rests long on that of Mammon. Your eyes meet his. You feel your heart beating fast and yet you can't stop looking at him with so much affection.

His cheeks redden, the heat of the blood pumping to his face and his head spinning. He also thinks about your lips, the way the palm of his hand touched your mouth, so delicate and so tender, and he thinks: "Would a kiss from them be that soft?"

✨️💛💛💛💛💛💛💛💛💛💛💛💛💛💛💛💛💛✨️

The leaves fall to the ground, you can barely notice their orange color. The trees lose their color and look sad, forgotten.

You think of the branches swaying in the wind. It is difficult to discern the shapes well, after all, it is always night here. The coming autumn means that your birthday is near and so is Mammon's.

You look away from the window to your right because you feel a familiar weight on your left shoulder. White hair and golden skin, the soft snore that comes from his mouth. You let out a slight smile.

"I love you" -you think- "I love you so much..."

"Mammon, Avatar of Greed, wake up or leave the classroom!" the teacher shouts, and Mammon wakes up groggily.

On the way home from RAD, you walk alongside Mammon like every day. It's the same old routine, but you love it. You love hearing his footsteps so close to you, his slim and defined body, much more taller than you, exuding so much warmth. It is a feeling of care, as if his body is emitting protection.

You swear that every day you walk closer to each other and you wish you could hold his hand until you reach HoL.

"I love you so much, Mammon. Do you love me?"

Hearing Mammon laugh thanks to your comments and jokes is one of the best things; then, a little push, and the rubbing of your uniform coat against his makes you feel butterflies in your stomach. Seeing his blue eyes full of light, you could swear that just that is what true joy is. Laugh with him and laugh at him; all the moments shared feed your heart.

It's already September... - he says.

Yes. It will be your birthday soon- you answer.

And yours- he grins.

What do you want for your birthday, Mammon? -

Mammon looks at you perplexed. You anticipated to his question. "I want you". Of course, this is just a thought of his, but now Mammon blushes. He can't stop thinking about you that way. If his brothers knew his deepest thoughts, they would wrap you in wrapping paper with a bow on your head and hand you to Mammon. Or maybe not, maybe everyone would hide you from him and his desires. Because Mammon's thoughts for you are carnal and lascivious, and yet they are full of love. They are not simply born from desire, rather, desire is born from his feelings for you: some pure, some dirty, some innocent, some perverted.

And as you look at his face and how his gaze evades you, you think about what you want for your birthday. And you cant help to think: "I want you". Your face turns red too.

The truth is that you can't live like this anymore. When did being with him, in this swing of emotions and crossed messages, become painful? You run and leave him behind. You want to cry, but try to hold it until you get into your room, and that must be fast.

Hey! Wait!- Mammon shouts.

You can't wait, what's wrong with you?, you left him behind. Suddenly, you feel something holding you back. Or rather, someone. Mammon stops you, holding you from your wrist -Why are you running?!

You can't escape Mammon. Did you forget that he is the fastest demon in the Devildom? Perhaps the fastest being in all the realms?

Hey... - his hoarse voice sounds more masculine than other times -What I want for my birthday..., I can't tell you. But the closest thing you can give me is to spend the day with me, okay? You can give me any present, but let's just...-

Your face turns to look at his. Red like a tomatoe. Something clicks in you. You remember what Levi once told you:

- I think there is no one who admires you more than Mammon does...

And you finally understand what he meant: Levi was not referring to Mammon's admiration to your efforts to be among the best students in the class, nor to how you have managed to adapt quickly from the human world to this one, nor to how you have managed to give yourself your place, and instead, you have made great friends, and definitely not to your bravery in front of Mammon or any of his brothers to avoid their fights or to defend him from Lucifer. Levi was referring to...

-Well, what do you want for your birthday? - Mammon tries to change the subject and thus hide his embarrassment.

-I... -Suddenly you become aware of the landscape around you. In the infinity of the night of the Devildom. Next to you, a lake that reflects the countless stars, the wind that blows gently, six pairs of footprints far in the distance, unable to hear you two. This is the moment. You feel it. The autumn air and the eve of your birthdays. Everything, all of this screams to you that it is the moment. After all, you've waited too long. Every day your heart darkens if you don't say it soon, if you don't say it now. From March to September, way too many months.

-I want a kiss from you, Mammon...-

You've never felt braver, it's like suddenly everything makes sense. Especially when you see his reaction. And how could you not confess like that when he looks so handsome; because the night light illuminates his face: his skin shines like grains of sand under the sea, his white hair has a pearlescent glow, and his blue eyes share the same color of the immensity of the ocean and, somehow, in this forever dim light is so noticeable. Mammon is like looking at a summer landscape on a beach in the human world. You know why you love him now, it reminds you of home: of the beaches that you visited as a child. His warmth and his affection it's like feeling the sunlight under the summer sun. Relaxed, free, happy.

Summer in Autumn.

Mammon lets go of your wrist, his facial expression displaying immeasurable surprise. Suddenly, the noise of the wind on the water reminds him of a conversation with Solomon that he had in this very same place not long ago:

-You don't know what to buy to Y/N for their birthday? Why don't you ask them what they want?

-You two are humans, right? Tell me what to give them. Aren't ya Solomon, whatever, the wise?

Solomon laughs.

-What's so funny?

-You. You are really funny, Mammon. Have you not noticed that their soul shines brighter when they are with you?

"I'm pathetic...", he thinks, "they were the one who had to confess first, and not me". You feel like you are being pushed forward. Your face falls onto his chest, and his arms wrap around you -I'm gonna steal ya on yar birthday, and I won't give ya a kiss, I'll give ya a thousand. No. Millions. And, and, and...-

You look up and meet his eyes, his bright red face, you notice his embarrassment and at the same time, his joy. Two such dissonant emotions can only coexist in moments like this.

-And will I have to wait so long for a kiss?-

Mammon glups and then, closed his eyes, taking courage, trying to keeping his bravado. But he realizes that at this moment, it is now impossible. -No, can I?- he asks, slightly shaking.

- Please, Mammon. You have no idea how long I've waited for you...- you say, your voice almost breaking.

A common thought appears in your heads as your lips met, a dim reminder of March 11th:

✨️ "No, their lips were softer than I imagined..." ✨️
