Obey Me Yandere - Tumblr Posts
I legit have NEVER seen a yandere Mammon fic and I love this. Because 100% I do love this man enough to turn a blind eye (also because he’s a demon and rejecting him can go very badly for me)


Could you maybe make a short fic of M/C plus yandere (preferably, Mammon) where at first it's non-consensual, but as the time goes on she gets manipulated into thinking it's all for love? I also think he should baby-trap her and do all kinds of shit to force her to stay with him.
Oh, my darling, of course!
I've been dabbling in the yandere smut side of the Obey Me fandom and HOLY SHIT it's INTENSE
Especially for my first love, Mammon-sama, I'll do anything for my sweet greedy boy 🥺🥺🥺
Lemme see what I have in my bag, my dear~

Enjoy.

Honestly, he couldn't tell you when it all started.
Probably when you'd first gotten here and he was told that he would be responsible for taking care of you. Yes, that sounds right.
It was then that these emotions started. These feelings toward you, the compulsive need to be by your side at every waking hour of the day. Hell, you'd have to kick him out of your room most nights just to get some privacy.
You were just so perfect.
Something about the way you spoke, the way you handled things, the way you carried yourself. He couldn't help but love all of it. All of you. He'd memorized every little thing you'd shared with him throughout the time you'd been in the Devildom, noticing whenever you cut your hair by even an inch or the slightest shift in your attitude to know when you were upset.
And when you were upset, he always needed to know why.
So he could get rid of your problem, of course.
If you were upset with one of his brothers, he'd go speak with them about it (as long as it's not Lucifer), if you were upset over failing to comprehend something mathematical, he'd explain it to you in five different ways to try and help, and if you were upset with someone the two of you don't consider close friends, he'd console you.
There was this one time, however, when consoling you wasn't enough. Not for him, at least. The first time these thoughts became more aggressive and obsessive. The first time he became truly dangerous.
_
Mammon narrowed his eyes at you, pulling his shades off so he could see you properly. "He did what?" He asked. It was more like he was demanding you to repeat what you said.
You hesitated for a moment before clasping your hands together and smiling. "He broke my D.D.D. and cursed me out for being a human." You sighed, shaking your head in disappointment. "It's alright, though. I'll ask Lucifer if I can get a replacement."
Mammon really only paid attention to the first sentence. He bit down on the arms of the shades in his hand and scoffed. "See, this is why ya should just keep someone around. As the Great Mammon, I shouldn't be botherin' myself with taking care of ya." He extended his hand, holding out an index finger so you couldn't interrupt him. "But, because ya really need it, I'll go ahead and be your personal bodyguard or whatever." He huffed out, a light blush forming on his cheeks.
You furrowed your brows. "Oh, thanks, Mammon, but I really don't want to bother you with this kind of thing. I really don't need 24-hour protection, I just really wish people like him would learn from their mistakes."
Oh, you were so forgiving. He couldn't help the way his heart pounded against his chest at the way you spoke so kindly about the bastard who broke your property.
He should kill him.
Mammon flinched, dropping his shades and freezing in place at the idea.
Something you need to know about Mammon is that he's not really a violent guy. Of course, he acts like a relatively tough guy, and his title as the second strongest sin in the Devildom wasn't just given to him because the king was feeling generous. He just never resorted to violence immediately, it wasn't the Mammon Way.
Now, though, there was another factor to account for in this equation of his.
You.
While his title made demons fear him enough to where he didn't need to act on any of his anger, he found it very difficult to stop his knuckles from twitching whenever he saw someone you as much as complained about.
However, he'd never thought about murder. At least, not so seriously. This was different. The image that appeared in his head was the demon you were talking about, chained to the back of his car by the neck, and being dragged all around the Devildom. Then, he'd kill him slowly. Maybe set him on fire, too. Yes, that sounded nice.
"Mammon!" You called out, snapping him away from his thoughts. You tilted your head. "Are you okay? You kinda blanked out there." You ask, placing a hand on his cheek to get him to look at you.
Mammon flinches at your touch, a dark blush forming on his cheeks. "O-Oi! I'm alright, human, now get your hand off'a me!" He gently grasped your wrist, shuddering in delight at the feeling of holding you.
You raised a brow, pulling your hand away. "If you say so... Well, Asmodeus wanted me to help him out in Majolish, so I'll head over there. You have a make-up class, don't you?" You ask playfully. Mammon scoffed. "Oh, come on! Ya don't gotta rub it in, MC. Ya jerk." You laughed a little. "That's what you get for skipping classes. I'll see you later, Mammoney."
_
He was there.
The bastard was there.
Mammon was a few seats away from the guy you were talking about earlier. The guy who broke your property and made you upset. He wasn't paying attention to the lecture, no, he was watching the demon. Staring. Glaring.
The scene that presented itself to him before, among many others, appeared in his head. Many of them were at the same levels of gruesome. The thought of getting rid of someone for you was a little nerve-wracking but satisfying nonetheless. It felt right.
After all, he was no longer an angel. And this was a lower demon, a being of impurity. That means that whatever happens to him down here, he deserves it, right?
This is what Mammon tried telling himself when he dragged the large black bag all the way to his room. The only one who saw him was Beelzebub, but the Avatar of Gluttony was busy with takeout, so he didn't really take the time to try and understand the situation.
Mammon was a little relieved that you weren't home to see this. At the same time, though, he did want you to know that he was looking out for you. You should be grateful that the Mammon is so adamant about protecting you!
"Say, ya think she might actually say yes if I ask her out? I dunno if I wanna do it now, but, I mean... Ah, who am I kiddin'? I'll wait a little while longer. It's too soon, don't ya think?" He asked, making another clean cut to the demon's torso.
The demon had stopped thrashing hours ago. There was blood everywhere, but the Avatar of Greed wasn't sloppy, so he'd placed a cheap mat underneath the chair that his classmate was tied to, planning to throw it away later. Even so, he became irritated when he got no response.
"Oi, I'm tryin' to ask for some serious advice. Ain't ya a demon? Why are ya dyin' so fuckin' quick, huh?" He seethed, glaring up at the lifeless expression that the demon before him adopted. He sliced an exposed arterie and scoffed. "Pathetic. I dunno why I bothered asking shit from a bastard like you anyway."
_
He refers to that kill as his "first slip."
Mammon had multiple "slips" after that, all of which he convinced himself were for your sake. Demons were going missing left and right. Of course, you didn't notice, because you were so naive. So oblivious. So cute.
You would never suspect Mammon to be the culprit, right? He was your sweet Mammoney. He'd do anything to keep it that way.
While he was growing to love you, more than he healthily should, he still couldn't build up the courage to talk to you. Confess to you.
You'd better believe he tried though.
The first time he did after he'd taken up his new "hobby" was during passing period at RAD. He had you caged between the wall and his chest, both hands on the wall to stop you from leaving. "Hey, human. I gotta tell you something really important, okay?"
Mammon had made up his mind to tell you then and there. However, now that he was right in front of you, now that he could see the way your expression seemed to glow in his presence, the way it made his heart beat so rapidly, he just... couldn't! "What's up?" You ask dumbly after a few moments of silence. He bit his lip for a moment before sighing. "Uh... Actually, I'll tell ya later. I just remembered I had to go do... Something, I'll cya around, MC." Then, he scurried, leaving you standing there all dumbfounded.
Curse his lack of bravery!
You were just so perfect, he couldn't bare the thought of you rejecting him.
His thoughts were swarming his brain. Thoughts of you. He would think often about how your hands would feel caressing his cheek. How soft your lips would feel against his. How tight your pussy would feel around his cock.
That last bit was, by far, the most popular thought in his head. He'd think about it when he had his hand wrapped around his cock, stroking and bucking his hips into his fist.
He'd imagine you underneath him, moaning and writhing while getting pounded into. The thought of you in such a fucked out state was just so delicious. He wanted you. No, he needed you.
But he still couldn't muster up the courage to tell you how he felt. So, he just settled for the next best thing.
Your panties.
When it was his turn to do laundry for the House of Lamentation's residents, he found a pair of white panties stained at the crotch. He lifted them up a bit closer for inspection and caught a whiff of the scent the pair of panties was emitting.
Your scent, your juices.
Your cum.
It was your cum.
Immediately, he felt himself hunch forward, clutching the nearly drenched panties in his fist as he slammed the door to the laundry room shut. He took a moment to process, a dark blush dusting his face as he held your panties in his shaking hand.
Mammon swallowed the lump of saliva he felt pooling in his mouth, staring at the crotch of your underwear, feeling his pants becoming a little too tight. "Fuck," He muttered out, quickly moving to undo his belt, sloppily pushing down his pants below his crotch, reaching into his boxers and pulling out his cock. Immediately, he started pumping himself, desperation evident when he started to buck his hips into his hand.
He caught another wiff of your scent and groaned, hunching over as he pressed his back against the wall. "MC," He moaned out, loving the way your name sounded rolling off of his tongue. He imagined you calling his name as well.
Whining and writhing underneath him as he pushed your legs apart.
"Fuck, fuckfuckfuck." He slammed his fist against the door, keeping his glazed eyes on your underwear. He imagined entering you. Your warmth would welcome him inside of your pussy and your walls would clench.
If only he had your warmth around him.
Flinching, his gaze shifted over to the clenched fist that was pressing against the door, your white panties being squeezed in his grip. He moved his hand, adjusting the pair of panties so the crotch was easily accessible, pushing it against the tip of his cock.
Mammon hissed when he felt your juices push against him, shuddering at the feeling. You must've put your dirty laundry basket in the laundry room the same day you masturbated. It was still relatively warm, and that was enough to make him imagine how your pussy would feel.
Wrapping your wet panties around his cock, he started bucking his hips, grinding himself against the crotch. He let out small pants and groans at the feeling, his hips beginning to stutter as he felt a knot begin to tighten in his lower stomach.
So good, so good.
He closed his hazy eyes, imagining how you'd start to squirm beneath him as he pounded into you, whining and crying out that you were close to an orgasm. "MC, fuck, baby, you're so fucking good for me," He hissed out. His hips never stopped bucking into your panties. Precum started oozing out of the tip of his cock, and he was smearing it against your underwear. "All mine," He murmured out softly.
The second-born clenched his teeth as his hand gripped the door knob, feeling the knot in his stomach tighten even more. The warmth that your panties provided, the visual in his head, and the sound that he'd imagine you'd made when you came; a mix between a whimper and a moan. It was enough to make his eyes go wide, a stuttered groan escaping his lips as he hunched forward a little.
Thick white ropes shot out of the tip of his cock, landing ontop of the juices that had already stained your panties. He inhaled sharply, covering his mouth as if to save whatever dignity he had left.
Slowly coming down from his high, Mammon panted heavily into his palm, a cheeks red, and vision still blurry from his orgasm. It made him wonder how hard he'd cum if you were there. If it was you wrapped around his cock instead of your panties.
But he'd take what he can get, he wasn't too picky when it came to you.
That's why he started stealing your panties, among other things. When your underwear wasn't enough, small trinkets and pieces of jewelry would go missing, only to be replaced by the Avatar of Greed himself. He loved to see the smile on your face as you looked at him, he loved to hear you thank him for gifting you such things.
You were so cute.
Too cute for your own good.
You mean so much to him. Too much for him to let you go.
He doesn't want you to leave. Ever.
_
Your eyes were always something he admired. He loved staring and getting lost in your gaze, trying to determine exactly which shade of which color painted your irises. He especially loved it when both of you got lost in the others' gaze. Inevitably, one of you would blush and look away.
What he hated was the way you looked at him right now.
Fear was present in your eyes. Tears started to gather on your lower lash line as your bottom lip trembled. "Mammon?"
Normally, he loved it when you said his name. It was like music to his ears, sweet like honey. However, this time, he flinched at the hesitation in your voice.
Of course, he couldn't blame you for being scared.
You'd been waiting in his room, unbeknownst to the white-haired demon, and he walked into his room covered in blood. That, and the horror that was the bloody bags you found in his closet.
His movements were quick. In the blink of an eye, he stood before you, slamming the door shut. He towered over you, the almost-dried blood that had been splattered all over his body was now right in your face. Leather black wings lifted and caged you into the corner by the closet, the leather on his body, as well as his horns becoming more apparent the more you took in his figure. "Ain't anyone taught ya not to go snoopin' around in other people's shit?"
You flinched at his tone. He seemed angry. That's when a tear fell. "Mammon, what the hell was that?" You ask, voice trembling along with your body. The demon before you was in no better state. He was panicking on the inside, trying desperately to form an explanation in his head. This caused him to stare intensely at you, eyes bloodshot, bat-like wings flapping gently beside you.
"S'just some of the trash that bothered ya, Treasure." Mammon's voice shifted from frightening to sweet, a huge contrast to his bloodied and demonic appearance. The new nickname made you shiver. Under other circumstances, you would've loved the fact that he'd given you a nickname, but you were too terrified. The nickname sounded so wrong to you. So twisted. "Most of them either acted out of line around ya, but some actually thought they had a chance!" He smiled, letting out a huff of amusement. "As if those lesser demons had the right to even look in your direction." He took a step forward, and you took a step back, your back now pressed against the wall.
This made Mammon frown a bit, bat wings flapping in slight irritation and confusion. "Why're ya backin' away from me, Treasure? I thought that... I thought that you'd be happy to know that they're gone," One hand pressed against the wall behind you while the other made it's way to your hip. "Aren't ya happy that they're not in our way anymore?" He tucked a few strands of hair behind your ear.
"Our?" You repeated. "What are you talking about our, Mammon?" He sighed, the hand on your hip traveling down to caress your thigh. "Us, Treasure. Our relationship, our love."
You closed your eyes tightly when he leaned in, lips brushing against your cheek as his voice dropped in volume. "Don't you love me, MC?" He asked softly, feigning an almost hurt voice.
You allowed a few more tears to fall as you pressed your palms against his chest. While it was true, you did love him very deeply, you just couldn't condone this. You weren't okay with this! Killing people for someone else isn't love!
Right?
"Mammon, you can't... You don't do this kind of thing for love," You said, hands trembling against him. His hand moved from the wall to grasp yours, clenching your fingers tight as he let a shiver run down his spine. He let out a deep sigh in bliss, feeling his cock twitch in his pants from your touch. "MC, Treasure, I love ya. I love ya so much." He then gripped your wrist, pushing your hand downward.
You flinched when your hand reached the bulge in his pants, fingers gently tracing the outline of his cock. "Baby, look at what ya do to me." He softly breathed out, turning your hand to push your palm against his hard on, his other hand gripping your thigh as he started bucking his hips into your hand. "MC, I love ya. I just wanted to make ya feel better," He looked down at you, the hand squeezing your thigh being used to lift up your chin so your eyes could meet his. "I got rid of the trash that was botherin' ya, babe."
You shook your head, trying to pull your hand away from his pants. Mammon's grip only tightened, an odd feeling beginning to pool in your gut. "Mammon, this isn't how you- Mmh!" He cut you off, leaning forward to capture your lips in a kiss. Your lips were so soft, he couldn't hold back the moan that escaped him as he started moving his lips against yours. His teeth started nibbling your bottom lip to ask for entry. When you tried to pull away from him, he let out a scoff, the hand that was on your chin moving to slap your thigh.
You opened your mouth to let out a gasp, only for Mammon's tongue to invade your mouth. He bucked his hips into your hand once more, his tongue exploring your mouth and burning your taste into his memory.
He moved his hands, pulling away from the heated kiss so his lust-filled eyes could meet yours. "That's right... I guess I should be showin' ya how much ya mean to me in other ways, huh?"
_
Mammon had pushed you onto his bed, climbing on top of you and capturing your lips in another hot kiss as he started to tug your clothes off. He was truly a being of pure greed, he couldn't get enough of you. He wanted more. And he wanted more now.
You pulled away as soon as you felt your breasts come into contact with the rather chilly air and threw your arms over your chest. "Mammon, wait, please! I don't want this!" You whimpered, tears beginning to stain your cheeks.
Mammon leaned in, one hand hooking around your skirt as he kissed you on the forehead. "But you love me, don't you, MC? I'll treat ya right, I promise." He brought a hand up to gently grasp your wrist, bringing your hand up to his lips and pressing a kiss to your knuckles. "I love ya so much, MC. Everything I do's for you, Treasure. The way I feel about ya, it makes me do crazy things," He murmured softly against your hand. "Please don't deny me."
His tone of voice made you think that maybe he was telling the truth, that maybe he did love you deeply, and that was why he went so far. Maybe this wasn't so bad.
No!
You snapped out of your hazy love-drunk mindset, realizing that the now-dried blood was still splattered all over him. It was someone else's blood. Maybe they were innocent! Well, they weren't if they were down here, but still! They didn't do anything to warrant such acts of violence.
With a swift motion, he yanked down your RAD skirt and panties, eyes shifting down to catch a glimpse of you. You tried to close your legs, but Mammon had managed to catch both of your plush thighs in his grip, pulling them apart and closer to him. Your ass was now on his lap, and your pussy was closer to his waist. He smiled at you, almost tauntingly. "None of that, baby," He pulled you closer to him, your pussy now a few mere inches from his face. Mammon took in the sweet aroma you gave off, letting out a deep sigh in bliss. This was so much better than your panties.
Suddenly, the pact mark on the back of your hand glowed a bright yellow. "Mammon, sto-"
He was faster.
Before you could finish your command, Mammon had torn a piece of fabric from your teal RAD under-blouse, pushing it against your lips to silence you. "Naughty girl." His voice dropped an octave as he glared at you. You had practically been folding in half with how close your knees were to your shoulders. The Avatar of Greed then adjusted the fabric in your mouth, pulling on the sides and tying it in a tight knot around your mouth. "I didn't want to gag ya, sweetheart," He cooed, shifting himself into his former position: where your pussy was a few inches from his mouth and your thighs were in his hands. "But ya just had to be such a brat. Playin' hard to get can get annoyin', ya know that?" His tongue lulled out of his mouth. He maintained eye contact with you as he lowered his face, dipping his tongue into your sopping heat and tracing the line of your slit. You moaned into the makeshift gag, arms trembling as one hand gripped the sheets, the other reaching behind your head to try and untie the gag.
Mammon flicked his tongue against the bundle of nerves that rested above your slit, smiling at the way you squirmed and whined. You knew this was wrong. He was a demon, and you were okay with that, but now you found out that he was a killer as well? No, you couldn't be okay with this. You shouldn't be okay with this.
But it feels so good.
You threw your head back and let out a muffled cry as his mouth latched on to your opening, thrusting his tongue into your heat. Your walls clenched around his tongue, and he let out a moan in response. He wondered how tight you'd be around his cock if you were this tight around his tongue. It made him think that perhaps you hadn't had anything inside of this pretty little hole of yours.
Wait.
Mammon pulled away from your pussy, a mix of his saliva and your juices dribbling down his chin. "MC, are you a virgin?" He asked softly, gold and blue eyes piercing through yours.
You looked up at him through tear-filled eyes and nodded your head slowly. The sound of wings flapping rapidly filled your ears, which made your eyes screw shut.
He'd be the first to touch you, the first to defile you. He was your first demon, now he'll truly be your first man. "Oh, Treasure." He lowered your body almost completely onto the bed, and your eyes shot wide open when you heard him fumbling with his belt.
You looked down to see his cock, flushed and hard, resting on top of your crotch.
He was huge.
Where he sat between your legs, his cock reached just above your navel. "M'sorry," He said softly, grasping his cock and stroking it a few times. "I can't wait any longer, Treasure. I have to have you before anyone else can."
You froze for a moment, realizing what he meant. You should've shaken your head or done something to deny him, to stop him.
But you didn't want to stop. You wanted to keep going. You wanted him to ravish your pussy, love you until he withers away. You pushed your head against the pillow, lifting your hands to grip the sheets beside your head, and spreading your legs open a little more.
"That's my girl," He cooed, pressing the blunt tip of his cock against your hole. You closed your eyes once more, trying to concentrate on breathing as he pushed himself into you. He was slow and sweet, pressing kisses to your neck. "Calm down, Treasure, I don't wanna hurt ya." His voice, so soft, so sweet, made you forget completely about why you were so against this at first.
Mammon grunted at how tight you were, his eyes glazed over. He was trying so hard to hold himself back. You were just so fucking tight. He let out a shaky breath, one hand going down to caress your thigh. "Loosen up, Doll," He cooed once more, clenching his teeth. He was so close to bottoming out, but your hole continued to deny him.
Tears had fallen down your face, staining your cheeks and the fabric that gagged you. You were in an entire different state of mind. The stretch hurt, but knowing that it was Mammon stretching out your cunt made your body feel more at ease.
When he shoved the last few inches of his cock inside of you, you couldn't hold back the muffled wail that escaped your throat. Finally, he was sheathed inside of you. His balls were rested against your plush thighs, and his tip pushed against your cervix.
"Fuck!" Mammon grunted out, burying his face into the crook of your neck. Your chest rose and fell as your breathing quickened. You tried so hard to focus on breathing, focus on calming down so it'd be less uncomfortable for you.
Mammon stilled, and you took that as a sign of him waiting for you to signal him to move. He wanted to take off the gag and hear your beautiful moans, but he couldn't risk you using your pact to stop him. He couldn't risk losing the chance to share his love with you.
While he was in his own head, he failed to notice your squirms and whines, replacing the pleas that you'd let out if you weren't gagged. However, his lack of movement made you impatient, and you wrapped your legs around his waist, grinding the tip of his cock against your the spot that made you see stars. Mammon's breathing hitched, immediately gripping your hips with his hands and looking up at you with a shocked expression.
Then, the surprised look turned into a smug one. "Just can't get enough'a me, can ya?" He teased, dragging his hips backward. You could feel him moving and thought he was pulling out of you. You were about to whine in protest, but you got the air knocked out of your lungs as he slammed into you, his cock pushing roughly against that same exact spot. He started thrusting into you, looking down at your pussy to see how well it swallows his cock, as well as how much of your juices can be seen (and heard). "You're like a waterfall down there, MC. I knew ya loved me, I knew it! All those demons weren't a waste of time after all!" He exclaimed excitedly, picking up the pace to align with the hype of his voice.
Your eyes rolled back as you felt him repeatedly pound into you, balls slapping against the plush of your thighs at his deep and quick thrusts. "So good! So good for me, baby," He threw his head back, letting out a groan as he felt you squeezing the hell out of his length.
Suddenly, he pulled the fabric from your lips so it rested around your neck. "Mammon!" You cried out immediately. He only grunted in response and grabbed the back of your thighs, pushing them up toward you so your knees were inches from your shoulders. "Fuck, Treasure, so— mMmh!— T-Tight!" He huffed out, mind feeling a bit hazy.
All he could think of was you. How much he loved you, how much he wanted to be with you. He wanted so badly for you to love him too. Now that he had you, now that he deflowered you, the Avatar of Greed couldn't stop there. He wanted more. And, in his sin, will he indulge.
If he got you pregnant, you wouldn't leave. You'd be attached to him no matter what.
The thought made his cock twitch and his hips stutter for a moment before regaining a rhythm, albeit faster than the one he'd adopted prior.
"M'gonna make sure—" He adjusted your legs in his grip— "You never even think 'bout leavin' me!" Mammon growled out, feeling the familiar knot in his lower abdomen beginning to form. By the way your walls were clenching so tightly around him, he could tell that you were almost at your peak too. "Gonna make you a mama," He purred out, rocking his hips into yours.
Your eyes widened at this, gripping the sheets even harder as you cried out. "Mammon! P-Pull o-out!" Your whimpers fell upon deaf ears. That, or ears that only heard what they wanted to. "You wanna have my baby, MC? Hm?" He asked, voice as sweet as vanilla, thrusts as sharp and hard as a blade. "Can't wait to—" He hissed as your walls constricted around him once more— "See the look on their faces! When they see you," Mammon chuckled darkly at the thought, greed, love, and obsession overwhelming his senses. "They'll see that you're all mine! I'll kill whoever gets in the way or disagrees! You're mine, MC!" One final thrust to that sweet spot of yours and you cum hard with a cry of his name, legs trembling in his grip.
Mammon couldn't stop. He couldn't stop going until he filled you up, painted your walls with his seed, and permanently intertwined your fates. "Mine! Mine, mine, mine! All mine! Only mine!" He growled out, burying himself deep into the warmth of your cunt and spilling his seed inside of you. He let out a lewd groan, rocking his hips gently to ride out his orgasm as much as possible.
Once the both of you came down from your highs, he pulled out of you, pressing small kisses to your tear-stained face. He lowered your legs to put you in a more comfortable position, wings and horns fading away as he pulled you flush to his chest.
In your exhausted state, you weren't able to think properly. "I t-told you... To... What if I... Get..." You muttered out, eyelids feeling heavy.
Mammon pressed a soft and warm kiss to your lips, one filled with love and care. "Shhh, sleep, Treasure. Ya did so good for me."
Maybe it was the way his words were sweet and stuck to you like honey. Maybe it was the way that he expressed so many times during this exchange that he truly did love you.
Whatever it was, there wasn't a doubt in your mind that the Avatar of Greed wanted you out of everything else in the world. Every valuable item, every treasure to be found, all he'd be willing to give up just for you.
He'd give for you, but he'd also take for you.
The lives of the demons he'd taken so far couldn't be ignored. At least, you shouldn't have ignored it. But he did it all for you. All because he just wanted you to notice him, to love him, and only him.
Eventually, you'd become accustomed to the blood on his clothes, the protectiveness, the obsession with keeping you close to him even though you never planned on leaving.
You didn't need anything else. You didn't want anything else.
All you needed was your first man.

This was fun to write, I hope you greedy-boi lovers enjoyed this!
My friend looked at the tags over my shoulder and said "Why are you like this?"
Thanks for requesting, I hope you enjoyed this, anon!
Irrevocably Yours
a/n: I always wanted to make a yandere x yandere fic. I feel like it didn't come off as dark as it could have been lmao.
Cw: Yandere x Yandere(which means usual talks about killing, love potions, confinement, etc), Yandere!Levi, Yandere!MC(but you're trying to do better), Double Penetration, Rough Sex, Levi having two dicks, some dub-con(there's protests at first but MC actually wants him), Fem!MC, kinda ooc.
----------------------------------
It was becoming too much—how you felt, the way your emotions churned inside you like a storm you couldn’t control. You were trying so hard not to give in to your usual behavior, to be normal, to keep it together. But the obsessive thoughts, the relentless impulse to take, to control, to own, were beginning to creep up, growing stronger with each passing day.
You’d managed to keep that side of yourself under wraps—relatively speaking—by focusing on anything and everything else. You buried yourself in distractions, anything to keep your mind off the darker urges. That was why you avoided relationships, why you pushed away any romantic feelings.
But that wasn’t enough anymore, because you were in love. Completely and utterly in love. The target of your affection was Leviathan, the shy, awkward, but endearing otaku. You hadn’t meant for it to happen; you’d kept your walls tall and unyielding, only offering detached friendship to the demon, just like you did with his brothers. But somehow, that detached friendship had morphed into an actual friendship.
You reasoned with yourself that it was okay to have a friend, as long as it didn’t become more. Friendship was harmless, right? You could handle that.
Wrong.
You quickly went from being just another normie to becoming his Henry, and with that came a shift you hadn’t anticipated. He started dragging you into his room more often, refusing to let you leave with those big, sad eyes and that lovely blush on his face. He’d ask you to stay just a bit longer, his voice tinged with a plea you found impossible to resist. Maybe your mistake was relenting so often, convincing yourself that you were doing it for the sake of your friendship, feeding into the denial that you weren’t crossing a line.
It was during one of those many nights spent gaming together that the truth hit you—like a bucket of ice-cold water. You were infatuated with him. The realization came when you found yourself wondering how you could keep him isolated, how you could ensure that no one else could be around him but you. The thought startled you, made you question everything. You were trying to be good, to do better. You couldn’t possibly be infatuated. That wasn’t you, not anymore. So you decided you needed to distance yourself from him, just a bit, so you could get over whatever it was you were feeling. It should have been easy, right?
Wrong again.
You didn’t anticipate Leviathan’s persistence. You thought of him as too shy, too easily flustered to chase after anyone, least of all you. But he never gave up. He whined in your ear, his voice desperate and needy, tugging on your clothes like a child afraid of being left alone. He even went as far as staying in your room with you, refusing to leave your side. It was so out of character, so unlike the Leviathan you thought you knew, that it rendered you speechless every single time. (And maybe, just maybe, another mistake you made was not paying closer attention to the hidden obsession lurking in his eyes, the way they darkened with something deeper, something more dangerous.)
Seeing such persistence warmed your heart, though. It showed you that he was willing to fight for you, to keep you close no matter what. Infatuation quickly turned into love—so completely in love. But just because you were in love didn’t necessarily mean it had to be obsessive or controlling, right? It could be a pure love, right?
Completely and utterly wrong. (And you wondered, in those rare moments of clarity, was anything you decided ever the right choice?)
The thoughts about being the only one around him consumed you. The maddening jealousy you felt when you heard him talk to his friends online, the burning urge to destroy all of his Ruri-chan merchandise—because how dare he love anything else but you?!—the overwhelming need to check all his electronics to make sure there was no one else… it all started to eat away at you.
All you could think of was him: Leviathan, Leviathan, Leviathan.
But still, you tried. You tried your best to fight it, because you were trying to do better. To be good. You wanted to love him in a pure, wholesome way. You didn’t want your love to be so obsessive, so twisted. But it was getting harder and harder to suppress the urges. (But were you really even trying hard enough, or were you just kidding yourself?)
It took all your willpower not to give in, but even with that, there were small things you did without his knowledge—like taking articles of his clothing, savoring the way they smelled of him. You took harmless peeks here and there at his computer and even his phone (and it wasn’t like he made it hard to figure out his passwords when he put it in right in front of you). Occasionally, you’d discourage him from going outside, convincing him it was safer, better to stay in. But it was all harmless, at least that’s what you wanted to believe, because at least you hadn’t snuck in a love potion to make him yours. (Not yet, at least.)
Still, you knew deep down that you couldn’t continue like this. The thought of hurting Leviathan twisted your heart—but you would, without hesitation, if he ever so much as looked at someone else. HE WAS YOURS. The intensity of your love for him made it clear that you needed to try again to put some distance between you, even if it meant spending time with one of his brothers instead. (It was almost laughable how desperate they were for your attention.)
That decision is what led you to your current predicament. It was your fault, yes, but your intentions were pure—at least, that’s what you told yourself. (Or was it that you were just too afraid to surrender completely?)
“I can’t,” you repeated firmly, holding your ground as you rejected Leviathan’s invitation to hang out. “I have plans with Beel.”
“P-Plans?” he echoed, his voice thick with disbelief, as though the word itself was foreign to him. His tone softened into a desperate plea. “Come on, it’ll be fun. Beel will understand if you cancel.”
The way he looked at you—so sweet, so hopeful—almost broke your resolve. But you knew you had to stay strong. “I already said I can’t. I’ll hang out with you afterwards.”
With one last, fleeting glance in his direction, you turned and walked away. If you had only looked back, you would have seen the dark, ominous scowl that had settled on his face.
When you returned from your outing with Beelzebub, who was sweet but unbearably boring, you found yourself debating whether to go see Leviathan. But you decided against it, reminding yourself of the need to maintain your distance, no matter how much it hurt. You clung to that conviction even as you ignored the constant stream of message notifications chiming from your D.D.D while you got ready for bed.
And maybe—just maybe—if you hadn’t been so completely lost in sleep, you would have noticed Leviathan standing silently at the foot of your bed, his demon form fully revealed, with slitted, orange-glowing eyes fixed intently on your figure.
This pattern continued for an entire week. You spent time with one brother after another, each day rejecting Leviathan’s invitations with an ache in your heart. But then, something strange started happening. Random pieces of your clothing—mostly your panties—began to disappear. Objects like your notebooks, chapstick, hair ties, and even pillows vanished without a trace. By that point, you knew it wasn’t just your imagination.
It made you want to scream. Someone actually had the audacity to take your things—and how dare they covet you when you belonged to Levi! The thought burned in your mind, making it nearly impossible to focus as Satan tried to engage you in conversation at the cat café. The soft meows and gentle purring of the cats around you did nothing to soothe the growing anger bubbling inside. Every time you saw a playful swish of a tail or felt a soft nuzzle, your thoughts drifted back to the house, to the annoyance you were going to have to deal with. You knew you’d have to investigate more thoroughly the moment you returned.
Once the two of you finally arrived back at the house, you were on a mission. Barely muttering a goodbye to Satan, you made a beeline for your room, your heart pounding with anticipation. The hallways blurred as you stormed through them, your mind solely focused on getting answers, to check and see if anything else went missing. Reaching your door, you flung it open with a force that made the hinges creak. But the sight that greeted you stopped you in your tracks.
Leviathan was sitting on your bed, his posture casual yet somehow possessive, as if he owned not just the bed but the entire space around him. His presence filled the room, and for a moment, you faltered, the anger you had felt earlier mixing with surprise and something else you couldn’t quite name (was it excitement?). You closed the door behind you, the click of the latch sounding louder than it should have in the stillness.
“Levi?” you questioned, your voice wavering slightly. The intensity of his gaze when he finally looked up at you made your breath catch. His usually soft and shy demeanor was replaced with something far more focused, almost predatory.
“Did you have fun with Satan?” he asked bluntly, his voice low and steady. The stillness of his figure, the way he didn’t move a muscle, made you instantly cautious. It was like he was waiting for something—for a slip, a crack in your composure.
“I did,” you lied easily, though the words tasted bitter on your tongue. The truth was, you had hated every second of your time with Satan, and it wasn’t just because of him. You loathed going out with any of Leviathan’s brothers.
Leviathan tilted his head slightly, his eyes narrowing as he observed you. It felt like he could see right through your lie, peeling back layers to uncover the truth you were trying to hide. The intensity of his scrutiny almost made you shiver. But then, as quickly as the tension had arisen, it dissipated. Leviathan looked away, his fingers beginning to fidget with his D.D.D. The shift in his demeanor was almost surreal.
“W-would you like to come to my room? We haven’t s-spent time together,” he asked, his voice softer now, almost hesitant. When he looked at you again, his eyes were no longer sharp and probing but soft and vulnerable.
You hesitated, weighing your options. It should be fine to go with him this one time. You told yourself you’d make it quick—just a few minutes in his room, and then you’d leave. The sudden foreboding feeling you had should had deterred you yet you chose to ignore it (or maybe you just didn’t want to see the signs right in front of you).
“Sure.” A word that sealed your fate.
As you walked with him through the dimly lit hallway, the anxiety grew stronger, tightening its grip on your chest with every step. Leviathan was close enough that you could feel the occasional brush of his arm against yours, and each touch sent a jolt through your body, heightening your unease. The closer you got to his room, the heavier the air felt, as if the walls themselves were closing in on you. You wondered if you would be able to bolt if things spiraled out of control, your mind already calculating the distance to the door and the speed you’d need to escape.
When you both stood in front of his door, the tension in the air was palpable, a suffocating presence that made your skin crawl. It was almost ominous when he opened the door and gestured for you to step inside, the sound of the door creaking open like a warning you were too stubborn to heed. As you walked in, your eyes darted around the room, searching for anything out of place, but everything looked the same. His usual setup, the familiar clutter of manga and figurines… So why were you feeling like th—oh.
Your breath caught in your throat as your gaze landed on his desk. Those were your items scattered across it, some new things that you hadn’t even realized were missing yet. And there, in his tub, nestled among his many sheets and body pillows, were your clothes, panties and pillows, arranged almost reverently.
You stood there, paralyzed by shock, even as you heard the door close behind you, the sound of the lock sliding into place echoing loudly in your ears.
“Levi, that’s… my stuff, my clothes,” you muttered, your voice barely above a whisper, but you knew he heard you. He was standing so close behind you now that you could feel the heat of his body radiating against your back, making you shiver involuntarily.
“Why have you been avoiding me?” he asked, his voice low and eerily calm, completely ignoring your statement as if it were irrelevant. His breath tickled your ear, sending another shiver down your spine.
This wasn’t what you expected. Leviathan wasn’t supposed to be like you, caught in the same struggle, battling the same obsession. The thought made your heart race. That wasn’t good—you didn’t want to be pulled further into obsession, into depravity. You wanted to be normal, to be better, to be good. You chanted those words to yourself like a prayer, a desperate attempt to cling to sanity, even as you finally turned to look at him.
He was looking at you with an intensity that made your breath hitch, his eyes locked onto yours as if you were the only thing that existed in his world.
But you couldn’t give in. You were determined to have a wholesome, pure romance with him. You had to resist, had to keep things from spiraling out of control.
“Don’t make me ask you again,” he growled, his voice dropping an octave as he grabbed your chin with a firm hand, his hold almost bruising in its intensity (and his aggressiveness shouldn’t have been so arousing to you).
“Things were getting too… intense. I just wanted a bit of space so things could mellow down between us,” you answered hesitantly, your words stumbling over themselves as you tried to make him understand. But even as you spoke, you could feel the flimsiness of your excuse, the way it barely held together under the weight of the truth.
“Intense?” He grinned, a smile that was more a baring of teeth than anything else, with an almost maniacal edge to it. His eyes gleamed with a knowing light, as if he could see right through you, as if he knew all the things you’d done behind his back, all the secrets you thought you’d kept hidden.
But you stubbornly kept your mouth shut. You could do this—you could talk him down, make him see reason. You would keep your distance and regain control (liar, liar, liar. All you did was lie).
“I know you want me. At first, I couldn’t believe it because why would you want me? But then, you started taking some of my clothes.” He looked deeply pleased as he let go of your chin, bending down to nuzzle his face into the crook of your neck. His breath was warm against your skin, sending a shiver down your spine as he spoke. “I could even feel your envy, your jealousy when I’d game with my friends or when I gave too much attention to anything else that wasn’t you.”
You sucked in a breath as he slowly nipped at your neck, his teeth grazing your skin in a way that sent a jolt of sensation through your body, heat pooling in your core despite yourself.
“I thought things were going well,” he paused, his voice darkening as he continued, “but then you started spending time with my brothers. You were ignoring my messages and invitations to come to my room.” As those words left his lips, the nipping grew harsher until he bit down on your neck deep enough to leave a mark but not enough to draw blood. The sudden sharp pain made you yelp and squirm in his grasp, but his hold was unrelenting.
He snarled at your attempts to break free, the sound vibrating against your skin, and you froze again, your body betraying you as a wave of desire crashed over you. You wanted to give in so badly—you wanted him to be yours. You wanted to be his. This side of him was so unexpected but definitely not unwelcome.
“I need you to explain yourself. Now.” His grip tightened as he fisted his hand in your hair and yanked it back harshly, forcing you to meet his gaze.
You licked your lips, trying to steady your breathing. “Levi, this just isn’t… healthy. I’m trying to do better.”
He scoffed, as if your answer was the most ridiculous thing he’d ever heard. “We want to be with each other. Does anything else matter?”
His words were tempting, far too tempting. But you wanted your love to last, to be built on a solid foundation (but really, you were just a fucking coward).
“It does matter. How about you let me go back to my room so we can think about this?” you suggested, your voice trembling slightly. The grip on your hair tightened, pulling at your scalp, and you winced in pain (but you wanted him to be even more aggressive, to show you how much he loved you).
“You, better than anyone, should know that you aren’t going anywhere. If I have to tie you up, then I will.” He released your hair with a sudden force and pushed you down onto the floor. The impact was harsh, and you barely managed to catch yourself with your hands before your head could hit the hard surface. He stood over you, a blank expression on his face as he watched you struggle to steady yourself.
“L-Levi, just calm down. We can talk about this,” you pleaded softly, your voice trembling as he dropped to his knees, caging you in his arms against the cold, hard floor. You could feel the heat radiating off his body, mingling with the coolness of the floor beneath you. If he kept pushing, you knew you would give in.
“For someone who wants me just as badly, you’re protesting too much.” His voice was low, dangerously calm, as he leaned his forehead against yours. His breath ghosted over your lips. “But don’t worry, I’ll fuck the fight out of you. And if that doesn’t work, well, I don’t mind using other methods if it means keeping you with me.”
His words sent a shiver down your spine, and you couldn’t help the way your body reacted. Heat pooled between your thighs, your panties already soaked through. You almost moaned at the sheer threat in his voice, and you wondered just how much rougher he’d get if you kept resisting. Would he lose control entirely? (You hoped he would.)
“Levi, please. We can’t,” you whined weakly, your resolve wavering as his lips brushed against yours. You somehow managed to turn your head away, but the gesture felt futile. The air around you shifted as he pulled back, his energy darkening. When you glanced up at him, his demon form was already out—scales glistening under the dim light, coral horns out, his tail swaying predatorily, and his glowing orange eyes fixated on you with an intensity that made your breath hitch.
“Fine, I guess we’ll do this the hard way,” he growled in your ear. The words sent your mind spiraling, and before you could fully process what was happening, everything became a blur of heat and sensation.
You gasped, eyes widening as his hand slid under your skirt with purpose, fingers expertly finding your soaked core. He moaned—a deep, guttural sound that sent a thrill through your body—when he felt how wet you were even through the thin fabric of your panties. It was the only confirmation he needed, the last bit of proof that you truly wanted him, needed him, despite your feeble protests.
With a heated urgency, his hands tore away your panties and skirt, ripping through the delicate fabric like it was nothing. Your shirt and bra followed, shredded under his impatient touch, leaving your skin exposed to the cool air and his hungry gaze. He didn’t waste a second, pulling you into a smoldering kiss that was all heat and desperation. Just like that, your resolve shattered, crumbling beneath the weight of your desire. You returned the kiss with equal fervor because you wanted—no, you needed—him so badly it ached.
He smirked against your lips when he felt you go pliant in his arms, the tension leaving your body as you surrendered to him. His mouth broke away from yours, only to descend upon your chest, his hot breath trailing over your skin as he left a path of bruising bite marks in his wake. Each nip sent a jolt of pleasure-pain through you, drawing breathless moans from your lips.
Your hands tangled in his hair, tugging him closer as he zeroed in on one of your nipples, his mouth hot and eager. He sucked on the small nub, his tongue swirling around it before his teeth grazed the sensitive flesh, sending sparks of pleasure straight to your core. Meanwhile, his thick fingers pumped into your wet, warm cunt—two at first, then three, and finally four, stretching you open with a pace that was fast and merciless. The sensation was overwhelming, the roughness almost too much to bear, but you craved it. You needed more.
He didn’t give you a moment to adjust, didn’t let you catch your breath as he fucked you with his fingers, driving them in deep with each thrust. His thumb found your swollen clit, rubbing tight, desperate circles that had you crying out, your body arching off the floor. The pleasure was intense, almost unbearable, but you loved it.
You hugged him closer, your whines and pleas for more filling the room, mingling with the sounds of your slick arousal as his fingers moved in and out of you with relentless speed. He was going to make you cum already, and you hadn’t even gotten started. His mouth finally released your nipple, leaving it glistening with his saliva, and he pulled you into an almost desperate kiss, his tongue plunging into your mouth as he curled his fingers just right inside you.
Your orgasm hit you like a tidal wave, crashing over you with a force that left you breathless. You cried out, the sound muffled by his mouth, and your cunt clenched around his fingers, gushing wetness all over his hand. He didn’t stop, didn’t slow down, riding you through your orgasm as if he wanted to wring every last drop of pleasure from you.
It was all so rough, so fast, but it felt so right, like this was exactly how it was meant to be. You could only watch with half-lidded eyes, your breath coming in short gasps, as he finally pulled his fingers out of your throbbing cunt. Your juices coated his hand and he brought his fingers to his mouth, licking them clean with a look of pure satisfaction.
But he wasn’t done. Not even close.
He leaned back, his glowing eyes never leaving yours as he reached for his zipper. The sound of it being pulled down was almost deafening in the silence that followed. He didn’t bother fully undressing, only tugging his jeans down just enough to free his cock—no, cocks. He had two of them, thick and throbbing with need.
Your mouth watered at the sight of him, and your cunt clenched on nothing as you imagined the sensation of him fucking you open on those thick, pulsating cocks. The mere thought made you shiver. You spread your legs wider, a silent plea, an open invitation that had him settling between them eagerly.
“This messy cunt belongs to me,” Leviathan rasped, his voice low and gravelly, as he rubbed both of his cocks against the slick folds of your cunt. The friction sent a jolt of pleasure through you, making you gasp as he gathered the wetness on the heads of his cocks, teasing your entrance with slow, deliberate movements. “You belong to me. I need you to remember that because I will kill anyone you so much as look at for too long. I don’t even want you leaving my room at all.”
You mewled softly at his words, the sound escaping your lips involuntarily, and you knew in that moment that there was no going back. You couldn’t deny it anymore—couldn’t even pretend to care how twisted your love had become, how unhealthy it likely was. All that mattered was that he was finally yours, and you would do anything to keep him that way.
“Do you understand?” Leviathan’s tone was harsh as he gripped both of his cocks firmly, positioning them at your entrance. He pushed forward slowly, just the tips breaching your slick, swollen folds. The stretch was intense, borderline painful, but the pleasure that accompanied it was undeniable. A high-pitched moan tore from your throat as your eyes became teary at the sensation.
“Levi!” you whined, desperation lacing your voice as you attempted to roll your hips down, to pull more of him inside. But his tail coiled around your waist, holding you firmly in place.
“I asked you a question. Do you understand?” Leviathan remained still, his gaze dark with lust, waiting for your answer. When you didn’t respond quickly enough, his hand moved to your breast, fingers tugging one of your nipples harshly. The sting made you gasp, a mixture of pain and pleasure that sent a jolt straight to your core. “Or are you so cock-drunk already that you can’t even answer me?”
“I—I understand,” you panted, finally finding your voice. You reached up, your hand tangling in his hair as you yanked him down, bringing his face closer to yours. “But that also means you belong to me. I will kill you and myself if you ever try to leave me.”
“Fuck,” he cursed, and you felt his cocks twitch at your words. His lips crashed into yours in a sloppy, heated kiss, all teeth and tongue, as if he was trying to devour you whole. The kiss broke only when he pulled back to latch onto the side of your neck that was still unmarked, his teeth grazing your skin before sinking in, marking you with more bruises that would be visible for days. And then, with a snap of his hips, he thrust both cocks fully inside you.
The stretch was overwhelming, the sensation of being so utterly full making you sob with pleasure. He didn’t give you time to adjust, his pace punishing as he pounded into you, each thrust harder and faster than the last. It was as if he were releasing all the pent-up anger from the week you had avoided him, taking out his frustration on your body. But you welcomed it, craved it even. You’d always loved the bite of pain with your pleasure, always been a bit of a masochist for it.
Moans mixed with cries of pleasure, the sound of skin slapping against skin echoing through the room. It was loud, lewd, and unmistakable, and you knew anyone within earshot would know exactly what was happening. But the thought only fueled your desire for him, making you arch against him, desperate to take him even deeper.
You felt another orgasm building, coiling tight in your core as one of Leviathan’s cocks hit your sweet spot with each thrust, while the blunt tip of the other bumped against your cervix, making you see stars. The sensations were overwhelming, your mind going hazy as you babbled incoherently, slurred pleas and moans spilling from your lips.
Leviathan’s eyes were glued to your face, watching every expression, every reaction. The sight of you—completely fucked out, cock-drunk and lost in pleasure—sent a surge of smug satisfaction through him. He moaned loudly, the sound almost desperate as he lifted your legs, pressing your knees against your chest, and somehow, impossibly, drove even deeper inside you.
You wailed as another orgasm tore through you, your cunt clenching and throbbing around him, the pleasure almost too intense to bear. He whined at the sensation, his own pace faltering as he neared his release. With a final, forceful thrust, he buried himself deep inside you and came, his hot seed flooding your cunt. The feeling of him filling you, marking you from the inside out, made you moan weakly.
He panted heavily as he finally stopped cumming, his breath ragged as he slowly pulled out, even as you whimpered from the overstimulation. Cum leaked from your thoroughly used cunt, trailing down to your ass as he admired the state he’d left you in.
For a moment, he just looked at you—as if memorizing every mark, every bruise, every inch of you that he’d claimed. Then, with surprising gentleness and a now adorable flush on his face, he picked you up, holding you close to his chest. He carried you to his tub and he climbed in, laying down with you on top of him, his arms wrapped securely around you as he pulled a soft sheet over both of you.
You snuggled closer against his chest, your eyes fluttering shut as exhaustion washed over you. The romance between you two was never going to be pure, never going to be simple. It was twisted, dark, and even dangerous—but it was real. You belonged to each other, and that was enough.
You would do anything to keep him because Leviathan was finally yours. And really, this was the best outcome you could have hoped for. Now, you didn’t have to go through with your darker plans of somehow knocking him out and trapping him somewhere. You only hoped he took you seriously about never leaving, because you truly would kill him if he tried. He belonged to you, after all.

warnings: mentions of manipulation, obsessive thinking/ behavior, mentions of being restrained
you’re not going anywhere

You had liked Lucifer, this was common knowledge to everyone around the two of you.
After all it’s not hard to catch the little glances you sneak his way, or the fact that you go out of your way to seek him out.
Lucifer knew this as well, and enjoyed the attention you would give him, frankly a bit too much.
As this continued the Avatar of pride found himself becoming completely infatuated with your presence entirely, to the point he began to want you all to himself.
He was never a fan of the way other demons looked at you, be it a low level runt or Diavolo himself. It pissed him off, so much so he began to think of ways to get you away from said demons.
So his first course of action was to make you his, and with a bit of manipulation and spoiling on his end he was finally able to get a solid confession out of you, which delighted him greatly.
However this possessive nature of his became worse when the two of you had begun to pass the five month period.
His brothers and even friends would mention his possessive behavior and ask if you were alright with him acting like that. You however brushed it off and joked that it was just Lucifer being Lucifer.
Little did you know, you should have taken their advice a bit more seriously.
It was the middle of the week and you had just come back from the Demon Lord's castle after having tea with Diavolo. Lucifer blew up your D.D.D with messages about where you were and who you were with, which in turn cut your visit with them short.
You made your way to his room slightly annoyed that he did that. Sure you forgot to mention Diavolo invited you to tea, but he didn’t have to get so bent out of shape about it and demand you come home.
Just as you went to knock on his bedroom door it flew open and Lucifer grabbed your arm and pulled you inside his room harshly.
“You sure took your time getting back didn’t you?”
“Look I’m sorry I forgot to tell you about my visit with Dia, but you didn’t have to blow up my phone and be psycho about the whole thing” you said giving him the same attitude he gave you.
Lucifer sighed and grabbed his face with his gloved hand. “This is what happens when humans have too much freedom” He spoke softly.
“Excuse me?” You replied annoyed.
“I should have kept you home more, otherwise I wouldn’t have had to stress trying to figure out where you were.”
You stayed quiet for a moment and looked at his unreadable expression.
“To make sure this doesn’t happen again you’re staying here from now on, where it’s safe I’m able to keep an eye on you.”
“What?! No way, I’m going wherever I want, there’s no way you’re putting me on house arrest”
“Who said anything about letting you walk around the house?” He replied. You gave him a look of horror as your heart dropped and began to run for the door.
Lucifer smiled as you tried to make an escape, it was a valiant effort, but he used a magic seal to restrain you as he carried you over to his bookcase.
He then grabbed a book and pulled it down causing the whole shelf to slide over revealing a small dimly lit room that was furnished with furniture that looked exactly like the one in your bedroom.
“I knew this was going to be useful one day.” Lucifer smiled as he brought you into the room.
“Now this is what I meant by keeping you someplace where I can keep an eye on you.”
The Avatar of pride put you down on the floor and watched as you struggled in the seal for a bit. After a few minutes you gave up trying to get free and then spoke.
“Lucifer..” you said as he loomed over your slouched figure.
“What is it now, little one?” He cooed crouching down to your level.
“Please let me go”
His face turned to one of annoyance then he sighed and began to caress your cheek. You looked at his hand with fear but soon glared back at him with whatever courage you were able to muster.
Lucifer scoffed and grabbed a fistful of your hair, then he slightly tugged you closer to him.
“Now you better listen here, because I’m only going to tell you this once.”
“You belong to me. You made that choice ever since you agreed to make a pact with me in my office that day, remember? So don’t go pulling out of a promise now.”
“Besides, the Devildom is a very dangerous place for a human, I don’t want you going out anymore and having to experience all those other disgusting demons who aren’t worth your time.”
“Instead be a good girl for me and stay here where it’s safer. You needn’t worry your pretty little head about anything else, I shall do my job and provide for you to ensure you stay healthy and comfortable.” Lucifer smiled, letting go of your hair and fixing the spot he grabbed.
“But Lucifer I don’t want to be here..!”
The demon frowned and looked at you sympathetically. After a second he stood up and began to walk to the other side of the room and mess with something in the corner. After a few seconds he turned around and walked towards you with what appeared to be metal chains.
Your face displayed one of pure horror and you tried freeing yourself from his magic.
“Now, now my love, calm down, I’m not going to hurt you” Lucifer said, patting the top of your head.
“Don’t put those things on me!”
“Don’t worry I won’t make them unbearably tight, however they might be a bit uncomfortable at first but you’ll adapt to it eventually.” Lucifer replied. He then knelt down and put chains around your ankles then placed them on your wrists.
Once the chains were on, you felt him pull them and attach them to a lock on the wall. As a result he did drag your body back slightly causing you to harshly slide across the ground.
Lucifer inspected the chains and once he deemed them secure enough he released the magic seal he was holding you with. Your body then fell limp and you suddenly felt very weak.
“What did you do..?” You asked glaring up at the first born.
“These chains are magic draining ones, so as a result you might feel sluggish at first due to being drained of most of your magic. That’s what I meant by them being uncomfortable. But as I said before, you'll adapt to them eventually.”
“Why are you going to such lengths to do this?”
Well if you must know, Lucifer said gently caressing your head.
“These chains are to ensure you can never leave me”
“I love you far too much little one, so in order to keep you safe and happy I have to make sure you’ll never be able to leave my side. Doesn’t that sound nice? Like I said before you needn’t concern yourself with trivial matters anymore, let me take care of everything, you just be happy and relax in here from now on.”
“Now then if you’ll excuse me I’m off to let my brothers know that you’ll be permanently staying in the human realm” Lucifer smiled then got up and walked towards the door.
The Avatar of pride then gave you one last glance before shutting the door, now leaving you in a locked dimly lit room chained up and tired.

➤ Day 16: Spell “It’s like you put a spell on me.” | Make your drawing magical!
-
He was so … polite when you first met him.
He visited the café you worked at with two other men and had asked for the person who had made the cake. You were about to leave when your colleague came to find you and told you all about the customer. When you went to the front and introduced yourself as the person responsible for all the cakes and other sweets that were sold he showered you with compliments.
Introducing himself as Barbatos, he asked you about the cake and later about your job in particular. You told him that you were a confectioner and all you could about the cake - except for the details you had changed in the recipe. It would still come out well if he wanted to make one himself just not exactly like yours.
He was very nice and easy to talk to but it didn’t escape your notice that his two friends were watching with great interest as he kept on talking to you. “Never thought he could be such a chatterbox,” the raven haired one quietly said to the redhead. So, it seemed he was normally more quiet.
It didn’t matter much to you, after all, you’ll probably never talk to him again. Still, it was a nice conversation so a smile came naturally to your face and you stayed quite a bit longer than normal.
Life went on like usual after that day until one day your colleague asked you to come up front again. To your great surprise you were greeted by Barbatos once more.
“I tried to bake your cake. It came out great but … not exactly like yours,” he admitted kinda sheepishly. It was actually really cute. “Yeah, that’s just because I don’t make it exactly like the original recipe wants you to, but if I told my little secret to our customers then who’d come here to buy anything?” “Ah, I understand.” He smiled sweetly and you happily smiled at him in return. He really was a nice guy, even though you didn’t know much about him.
The next time you met him was by chance. You were on vacation and just strolled through town a little looking at the window displays of the shops when you felt a tap on your shoulder. Needless to say that you were quite surprised to see him standing behind you as you turned but you soon had forgotten about that as he engaged you in a lively conversation. He was so easy to talk to and pretty soon you found yourself on a bench in the quiet part of the park talking to him.
Nothing special. At first you had talked about the day - what you were doing and that kinda stuff - and then a little more about cakes. Then the topic shifted a little to be about what he was doing - seemed he was some kind of butler.
“It was really cute seeing you the other day. You were on the playground with a little child.” “Well, yes. I was looking after my nephew.” That was weird. You were sure there were no other people around that day. Barbatos seemed to catch on to your sudden discomfort and changed the topic.
“You know, it is really bewitching.” “Bewitching? What is?” That sudden remark caused you to smile a little in confusion. He smiled back at you. “Your smile is. It’s like you put a spell on me.” Your expression went blank and you shifted in your seat causing him to raise a brow in question. It wasn’t even two months ago when you broke up with your last partner in a very unpleasant way, so you didn’t really like the way this conversation was going.
“It was really nice meeting you again, Barbatos. I gotta go now.” As abruptly as you stood up you didn’t notice his expression changing. What you did notice was when he caught your wrist to stop you from leaving. “I’m sorry Barbatos but I really have to go now.” When he looked up at you he had a polite smile on his face that didn’t give away his real emotions. “It’s so nice hearing you say my name.” Startled, you looked at him. He was right. It was the first time you had actually used his name. “Could … could you let go of me now?” “Can you say it again?” His expression remained unreadable. “Barbatos” you said, pulling your arm to remind him of your request but he didn’t let go.
“You know, I wanted to be patient but coming here isn’t that easy for me and I can’t leave my Lord Diavolo all to himself over a prolonged period of time …” He seemed to think about something while you stared at him confused. What was he even talking about?
“Yes,” he finally said “I think it’s best if I just take you with me. Then you can just show me how you’ve changed the recipe of your cakes.”
You stared at him in confusion that soon turned to pure horror when his appearance changed in front of you: Somehow he suddenly had strange bone like wings attached to his head but what caught your attention more was the split tail loosely wrapping around your waist.
Terrified you tried to get out of his grib yet even though he wasn’t holding you with much force you couldn’t get his hand to open no matter what you did. Barbatos continued to smile at you and even tried to calm you down a little but you didn’t want to be calmed down. Breathing way too fast you still tried to get your hand out of his hold until you felt too dizzy to continue your struggle. Barbatos easily caught you once your legs gave way.
“Don’t worry, (y/n). You’ll like it.” That was the last you heard before you blacked out.
He was so polite when you first met him.
How could you have been so wrong?
