Obey Me! X Reader Oneshots (Mostly Mammon)

💛 mammon x reader 💛

You sat down at the dining table for breakfast, everyone but Mammon was there. As per usual, Satan was reading, Asmo was flirting with a mirror, Beel was basically eating the table, Levi was gaming, Belphie was sleeping, and Lucifer was minding his own business.

"Does anyone know where Mammon is?" You suddenly asked, gaining the attention from all of the boys. "He's usually not this late."

"That scumbag?" Asmo scoffed and rolled his eyes as he put the hand mirror down. You frowned at the label that everyone seemed to throw at the second born. "He's probably off stealing someone's wallet or going through stuff in the house to could sell."

"I locked all of my Ruri-Chan merch up so he can't get to it this time," Levi looked up from his game. "That idiot will get some pretty high voltage if he even goes within five feet of my door."

It annoyed you that they all said hurtful things about their own brother, both to his face and behind his back. Sure, he wasn't a brainiac, but he wasn't a dunce either... Sometimes. You didn't like that they treated him like trash. After all, you knew what it felt like to be the 'disappointment' of the family and it really hurt.

"I hope he doesn't ever come down from his room," Satan muttered, flipping a page in his book. "Everytime he enters the same room as me, I get a migraine."

"He's so noisy that it's hard for me to sleep. I wish he'd just disappear," Belphie yawned. He had apparently woken up at the mention of Mammon and decided to add his two cents.

"He ate my custard," Beel frowned as he remembered the tragic day he lost his precious custard.

"I'd have much less of a work load if he wasn't such a nuisance," Lucifer nodded, seemingly annoyed at just the mention of his brother.

Rolling your eyes with a scoff, you pushed your chair out and grabbed your plate, "You guys are unbelievable."

"I don't know why you care about that lowlife," Asmo sighed. "He's basically as useful as sunglasses without lenses."

"He's not a lowlife," you glared at the brunette. He flinched, you were usually so kind to him but something had obviously pushed your buttons.

"You don't need to try to defend him," Levi huffed. "He knows that he's a good-for-nothing, unlovable, worthless, scummy, low--"

"What is wrong with you guys?" You interrupted him, sloppily throwing your plate back onto the table. The loud bang startled everyone and they looked at your trembling figure with wide eyes. "He's your brother!"

"I wish he wasn't..." you were too angry to identify who said it, but it really pissed you off.

"How could you say that?" You ran a hand through your hair, laughing bitterly. "I know that he's a bit clumsy when it comes to showing affection, but it doesn't mean he doesn't care. Like when he bought Levi a gift when he was upset about not winning a drawing. Or the time he let Asmo dress him up with new clothes from Majolish. The fact that he doesn't beat the shit out of you guys, other than Lucifer, shows that he cares! We all know that Lucifer is the only one out of you all that he couldn't beat to a pulp."

"Maybe you should calm down--"

"You call him scummy and a lowlife just because he's a bit greedy?" You threw your arms up, not noticing that the exact demon you were talking about had walked into the room. "You're all greedy for something! Just because he wants money, doesn't mean he's all those awful things you call him.

"Lucifer is greedy for perfection, Levi is greedy for what he can't have, Satan is greedy for being pissy, Asmo is greedy for sex, Beel is greedy for food, Belphie is greedy for sleep! What makes you guys that different from him? Huh? Just because he want's something material doesn't mean he's worth less than any of you!"

They were all stunned. Nobody had seen you get mad before, let alone yell at six of the most powerful demons. You were so furious that your face had turned a light pink and your body had begun to shake.

A gentle hand was placed on your shoulder and you turned to find Mammon standing there with a slight frown, "It's okay, you don't have to get upset for me. I'm used to it."

"That's the whole point," you slapped his hand away and stepped back. "You shouldn't need to be used to it! What they're doing is not okay! I know what it feels like for your whole family to hate you and I know how much it hurts. So the fact that the person I love has to go through that every day literally breaks me."

The room was silent as everyone took in your words. You didn't realize what you had said until after it had already echoed throughout the room. Clearing your throat, you turned away with glossy eyes and left the dining hall.

Everyone else was left in stunned silence, some feeling guilty, some feeling upset, and one feeling ecstatic. Mammon's face lit up as he realized that you said you loved him and he nearly jumped around with joy. He couldn't stop the goofy smile that spread across his face.

"Mammon... {Y/N} made a good point," Beel broke the silence. "I'm sorry. I'll try to not call you those things in the future."

"Thanks, Beel," Mammon ruffled his younger brother's hair. "I'd love to stick around and hear ya all apologize, but I've got somethin' I gotta do."

He bolted out of the dining room, that same stupid smile on his face, and booked it to your room. Mammon hesitated when he heard soft cries coming from the staircase at the end of the hall. Instead of going into your room, he followed the sound up to the attic and found you curled up on the bed, holding one of the pillows as you cried.

"{Y/N}?"

You jumped at the sound of his voice and quickly wiped away your tears. He walked to the bed and sat on the edge while you slowly sat up, turning to look at him. Even with red, puffy eyes and messy hair, Mammon thought you were the most dazzling creature he'd ever seen.

"Look," you sniffled and turned your head away. "Just forget what I said back there, okay? I don't want things to get awkward betwee--"

"Hey, hey," Mammon chuckled and grabbed your hand, lacing his fingers with yours. "Don't think ya can get out of this that easily. I can't just forget when someone as stunning as you says that they love me."

"S-Stunning?" Your gaze quickly turned back to him and you locked eyes. The cobalt blue was striking and had he not begun speaking, you would've drowned in it.

"Though, I guess I could forget... for a price," Mammon smiled mischievously. He slowly leaned closer and you found yourself also moving toward him. "But I don't want any money..."

"What do you want, then?" Your eyes flickered down to his lips, then back up. The two of you were so close that you could feel his warm breath fanning over your face. "I'll give you whatever you want."

"I want your soul," his smile didn't falter. "I want you to give yourself to me. I'll be your first and only demon, got that? You'll be mine."

"Deal," you whispered.

"Seal it with a kiss, darlin'," he squeezed your hand.

His words gave you the green light and you didn't hesitate to press your lips to his. Mammon moved his free hand to the back of your neck, afraid you'd pull away if he didn't. You placed one hand on on his chest and grasped the fabric.

"Are you done?" A voice came from the doorway. You both broke apart and saw Belphie leaning against the frame. "Are you done?"

"Belphie, I love you," you sighed, removing your hand from Mammon's shirt. "But if you cockblock me one more time--"
