"Be my darling!"

He tilted his head, as if watching an animal perform an unexpected trick and he didn't know how to feel about it. It sounded strange to be called that, even more by his own lover. "Humans really do find creative ways to deal with their time."

Days later, you kept repeating the nickname whenever you saw Jester acting in a way that could be interpreted as "maternal". His silence grew longer with each occurrence. He was letting you have your fun for now, while he was still in a good mood.

But it grew old quickly. Irritated him even more when Harlequin learned about it and started calling him mommy, too.

One troublemaker he could deal with, but two was too much and he didn't had patience for it now.

Finally, he closed the book he was reading when, after a hard day at the circus, you called him mommy again. "The joke's lost its humor, my dear."

His violet eyes narrowed behind the mask. "Don't call me that again." His voice remained calm, almost gentle, but there was an unmistakable weight to it. It wasn't a request, but a newly established rule. "There will be consequences."

Humans are strange creatures, he thinks. He watched as you leaned in, taking a deep breathe with a barely contained giggle under it.

"I'm sorry, mommy, I'II behave. I promise." You snorted, staring at his face as if it was hilarious how incredulous he got. Perhaps, you should had heed his warning.

Because you were in a kind of situation here. You were bent over on his lap. The sensation of his knee pressing into your belly was uncomfortable at times, and you struggled against him in a futile attempt at escaping. His left hand was keeping you in place, making you pliant and soft as with his other hand he rubbed your clit with his thumbs, rolling the little nub between his fingers, drawing out all these cute noises out of your throat that you tried to stop from coming out.

"You see, this isn't even the punishment you deserved." He muses softly like a flower blooming slowly, deliberately waiting for an answer just so he could continue his caress - that never came because you were still trembling from the tenth orgasm he had pulled from your body.

His teasing felt like a whip, merciless, keeping on the verge of another orgasm just to ruin it at the last second. He was enjoying that a bit too much, as he watched your body shaking, as he caressed your ass and hips with a smile.

"Cat got your tongue, huh?" He stared down at you, your legs spread like a present, your back littered with his marks, in special he liked to stare at the mark at your neck that marked you as his mate.

He licked his lips. His eyes got dark with a hint of corruption and obsession, as he would be the first and last creature that laid his mark upon you. His annoying lover who made a mission in irritating him. "You're not going to admit you're in the wrong, my dear? How many more orgasm I have to pull from you until you're trembling and crying?"

"Ah- mommy, you s' cruel. Was just a tiny joke " You moaned between gasps for air, but that only served to send heat into his loins. And he resumed his ministrations. That hellish pleasure went on enough to make you cum again that night.

Many more yet to come and he hadn't even entered you yet.

"You're not learning anything, are you? Maybe spanking will teach you more discipline."

As you walked toward the kitchen and cursed the teacher for several minutes, damning yourself for your class having to put on a play during the summer festival, you found Opera. Sitting on one of the chairs doing absolutely nothing, they looked at you with a grin from ear to ear.

"Just the person I wanted to see right now, my star!" They exclaimed, making you frown. You grabbed some things to eat on the way as you watched your lover get closer and closer to you. You felt your cheeks burn all the way to the tips of your ears — you were already melting because of their approach, and they weren't helping either; you could feel their breath on you, tempting you, as they giggled softly.

Their warm breath hitting the sensitive skin of your neck and their fingers lightly tousling your hair. You weren't able to push them away. The sight energized you greatly, and they knew it. They were hoping to help you somehow, even if only through some kisses and a massage. It was their way to show their support for you.

Opera wasn't in the same class you were, and their class was also busy with presentations. It was one hell of a month full of rehearsals, but at least they always got up a little more earlier just to have breakfast with you and see you in general, even if you always had lunch together during break.

"I want to see you slay it as the protagonist! Show them what you're capable of, my love! Leave everyone breathless with your perfection! Leave everyone wanting more and more." Opera wrapped their arms around your waist and hugged you tightly.

You returned the embrace with the same intensity, nodding. You stayed like that for a few more minutes, until they pulled away and gave you a light peck on the lips. It was so quick that by the time you realized what had happened, Opera had already pulled away and was walking toward the front door wirh a smug smile on their lips, tail twitching with malice as they turned around to see your flustered face.

"Your mouth is so warm and soft. But if you want more kisses, you're going to have to perform perfectly." They left, leaving you behind. However, not for long — with a determined smile and renewed strength, you ran to catch up with them.

-ˏ` He watches you from afar, not interfering much, at first. But with time, I can see him slowly redirecting your attention to somewhere else, maybe something he knows a lot and can be of help, too. The time spent on his office with him is quiet, but comfortable enough that you don't feel afraid of him - he knows he can give people the impression, but it's all he ever knew. Control and discipline. Unpacking trauma and changing takes a long time.

-ˏ` His gestures are calculated, his words rehearsed, as the one responsible for the exchange program he keeps you closer than he keep the angels or Solomon. He say it's because you have no magic, so he must be there for you in case you need his assistance. It's an offer you're happy about, even more when you can ask him about demon culture or other things pertaining Devildom; you don't realize yet but passing this much time with him start to shape the way you act and travel through Devildom, with calm and obedience instilled in you.

-ˏ` Later into the program, it's common for you to drink tea together and play chess, read books or just work into your assignments. It's a routine reinforced by small treats and gifts Lucifer gives you, something to keep you this way so you don't realize the hand that holds your leash. While working does get boring sometimes, he tends to put on some music on his record player and invite you to waltz with him. Lucifer also loves to hear you talk about your childhood, hoping somehow that it was better than his, that you didn't suffered too much growing up, at least someone had to be happy.

-ˏ` Loves to hear you speaking actually, it makes the voices on his brain to finally go quiet, the fears, the doubts and insecurities are all silenced when you're talking about your latest interest or something you were dragged into by his brothers. He should feel annoyed by that, but his brothers are so funny sometimes that he can't help but laugh at their shenanigans with you. He's fond of them just as he's fond of you. He looks at you like this btw: 🥺💓.

-ˏ` As the exchange program is nearing its end, he had successfully you wrapped around his fingers. Though he's a master in his game, rewriting facts into hypothesis, molding feelings and feeding them to you with a soft understanding that it takes time for you to chew on them and interpret them the way he wants you to. Lucifer opens up slowly, because being vulnerable is still foreign for him, he starts praising and complimenting you more often, flirting with you restlessly to the point your whole face is burning in embarrassment. When you forge your pact with him, it seems the roles still get reversed; as he acts much more like your master than you act towards him.

-ˏ` Lucifer knows he’s possessive in his love, the way his eyes mark you, the way his hands itch to touch you, though he sees nothing wrong with it. Rather, he prides himself on it and tells himself it’s with the best of intentions that he keeps you trapped in his room when the program ends. So what if you can't return home? You're right here, in your new home, with him (and his noisy brothers, too). There was no way in hell he would have let you return to the human world after entering his heart and making it your personal place. Someone doesn't just enter the Avatar of prides heart and plan to go away after.

-ˏ` Losing your sheep qualities, devoid of that naivety, rebeling against him makes himself even prouder. Because, sometimes, he'd prefer you to rebel against him or the things he been doing. It's his dirty secret, if you will, seeing your face contort in anger and rage, feeling the way your heart races, the way you fight back in every step; you're the most perfect pet he had designed and you're about to burn out if you keep fighting, but that's alright, he'd be here to collect your pieces and put you back together again.

-ˏ` He is most doting, that's true, bringing your favorite food, combing your hair and helping you getting dressed, letting you pretend that you're still in control, even though you're starting to go quiet and disassociate, lost inside your head since you hadn't found a way to escape his room for weeks on end and his brothers doesn't seem to be of help (that would be because he turned his room to be soundproof with his magic). When you fight, you only feed the sadistic nature within him, because he rather you cry than him, that's why you aren't allowed to go away.

-ˏ` He would feel lonely and that's something he doesn't want to. He felt that way too when Lilith died, when he made his brothers fell from heaven because of him and guilt is something he doesn't want to feel again. He doesn't want to feel guilty when he thought of the infinite scenarios where you forget about him, where you get married with another person, when you go on with your life, leaving him behind just as another face you met once.

-ˏ` As merciful as he can be, his patience isn't something to be taken for granted because it has a limit. And while it is funny when you're acting bratty and moody, he has rules for you to follow and not following them earns you a punishment. Mostly is depriving you from food and water for days. There's no need for physical punishment when he can let your own body punishes you with their physiological needs. There's no need for him to move his hand when your mind is your greatest enemy, creative in its own way in torturing you with your imagination.

-ˏ` But if you don’t break the rules, then he will continue to lovebomb you like he used to do with his gentle words, with his kisses, and limited freedom when he takes you out in the middle of the night. His gifts now consist of things that have his name on it, like personalized necklaces, for example, or peacock themed since that bird represents him, or red clothes; he is very creative, that's for sure and he really love seeing you matching with him, it feeds his pride just right. If you have a pact with him, he will give you clothes that expose his mark for everyone to see that you are his, his lover, his pet, his.

-ˏ` He likes the period where the fight leaves you, where you're hollowed and quiet, when he can collect you like a doll and have you sitting in his lap as you nuzzle your face into his neck. Your humane smell calms him as he breathes in, humming softly as you close your eyes and drift into sleep, the sound guiding you to rest. Your weight above his grounds him. It keeps him in the present moment as he traces circles into your back, as he watches over you as you sleep.

-ˏ` Lucifer loves you, even in his twisted way. And he will make you love him too.

ㅤ

-ˏ` Mammon is very sweet and suffocating like a new puppy that keeps following you wherever you go. It's cute in a way because his friendship and love is something innocent and shy, as he guides you into this new world with a soft smile and a tsundere attitude. He's happy, for the first time in a long time, he's really happy. You're like a fresh air in the middle of the desert, and he's breathing like he was drowning, as he keeps on taking you with him to his favorite places, being so uniquely him that you can't help but being intoxicated with him. Again, cute as a puppy, but that's the image he's purposely using specifically for you as it makes you trust him more easily.

-ˏ` Things with Mammon will always be paradoxical, not because he's pretending to be something he isn't, which he does a lot of times, even with his brothers. But because he has secrets and sides you may never know that only comes out when it's inevitable, for anyone else he may he scummy, an idiot, but for you, he's not like this, he isn't perfect, he's flawed just like anyone is and that was make him perfect, because he keeps trying to be better each day. His greed stems from fear of loss; watching his sister die without being able to do anything, losing his home, his place as an angel as he followed his older brother to hell. Not having an identity in Devildom, being denied acess to every single establishment because he was an angel. Things like this warped his vision, him, in general.

-ˏ` You don't know the length he would go to keep you exactly as you are, exactly clueless to all he's doing in pushing away any demon trying to befriend you or that have other intentions, according to him, and as the demon responsible for you, of course you trust his judgment. Despite his cute attitude and words, inside him lie something much darker and dangerous, almost imperceptible and quiet, but when it explodes it consumes everything. He's much more forced as a yandere imo. We know him from the games always proclaiming he's Mc's first and as their first he would stay unique. I don't think he'd allow you to make pacts with the other brothers.

-ˏ` You're his master. His mate. His treasure. His! Mammon doesn't have any interest in entertaining his brothers and share your attention with them. Rather, he redirects your attention to him always, learning how to read you just so he can influence your moods and desires at that moment. He always take you on little dates, paying for absolutely everything you want, matching clothes, plushies, whatever you desire. He spoils and he spoils you rotten. He even gives you allowances.

-ˏ` I honestly don't feel like he is the most dangerous yanderes between his brothers, simply because he contains a lot of his more violent tendencies for your sake. He would avoid things that make you hate him like kidnapping you or hurting you in someway, he make it seems that among his brothers he's the safest option for you, even if that isn't entirely true, because while he doesn't hurt you explicitly, other people around you receive his brute force 100% without you ever knowing what had happened to them.

-ˏ` Yet, as contradictory that is, he likes showing you off and having others know that they can't win your heart. It's already his for the taking and he takes very good care of it, when he's not paying up his debts, he's spending all his money into you, whether you want it or not. Each day you're given a new gift. Small things like a new eraser or a new pen. Then, a new phone, a beautiful wristwatch, diamond earrings, and if you don't stop, he'll keep going.

-ˏ` Very attuned to your moods and thoughts. He's comforting when you needs him to be, funny when you needs him to be, quiet when you needs to think a little. For someone who can be so greedy and needy for your attentions and affections, he's also very considerate with you Mammon loves you and would do anything for you to always be happy. He considered giving you a love potion once - just in case things went south somehow, but that's the only boundary he would cross that you know about.

-ˏ` During your sleepovers, he likes collecting things from your room: hair from your brush, used underwear, a gloss or two, nothing that you'll miss much. But for him? These are his absolutely treasures and they immediately entered his shrine, which he likes to stare a lot because it smells just like you. Alone in his room, he likes remembering all the nicknames you give him, all the hugs you exchanged, all the cheek kisses, all the stares. He could die happily just like that.

-ˏ` He is soft and sweet until you try to leave him for whatever reason it is, in this scenario he starts to freak out, asking for another chance to be better, hyperventilating as he cried and begging for you to stay.

-ˏ` Leviathan's envy is something to be studied. It's a painful feeling that occurs when he realizes he lack something, coming from a place familiar to Mammon's, it started right after the fall when he watched everyone around him: they had no worries, no fears, they had a stable roof over their heads, they had food in their tables and beds to sleep. His brothers had too, but was it really theirs to start with if Lucifer had to work for the Prince? Was the House of Lamentation really theirs if Diavolo stopped paying for it? Was anything in Devildom really theirs?

-ˏ` Levi feels guilty being envious of everything around him. And he feels even guilty when he start isolating himself in his room, playing endless games, watching endless animes until his eyes are red from sleep, just so he won't focus on feeling and processing everything he went through and how he will never be the same. It's not easy confront these things, but he doesn't even want to try. He's afraid and he doesn't even admit out loud.

-ˏ` Meeting you left an impression on him. He doesn't know why, though, but it's addicting and he founds himself orbitating around you like a star trapped in a blackhole. He's a very delusional and suffocating yandere, but he tends to hide it well behind his envious facade as he slowly makes friends with you, learning about what you like, what makes you, well, you. For the first time in a long time, he's interested in something else other than animes and games, he's interested in you.

-ˏ` He's still a bit shy around other people but everyone can see him going out more, mostly with you. He tends to depend a bit on your support, especially when he's having a bad day and can't manage or handle doing things. Your moods also influence his; if you're happy then so is he, if you're sad then so is he. He experience life a lot through your and your accomplishments, a bit envious he couldn't be there when you achieved something, even if that happened before the exchange program.

-ˏ` Levi tries first to appeal to his shyness and awkward conversation skills to make you stay with him and play with him longer, he mostly does that when he feels that you haven't been spending a lot of time with him. He has everything he needs in his little fortress of a room, since he spends most of his time there. Food, drinks, blankets, games, animes, mangas. Yes. He has everything you need in there. He may or may not have some of your clothes there too, but he totally didn't stole there, he mentions how you must have brought with you (you didn't).
