a/n: Hello! I know I haven't posted anything original in what feels like YEARS, but saying the last several months have been wild is an understatement. This is a request/dedication to @otromeru who is an AMAZING artist and one of my fave Obey Me! Fanart blogs. I love Neru, and I love her and Mammon's relationship. I hope you all enjoy it!!!
Warning: SMUT, oral f! receiving, mild voyeurism, Lucifer being a dick
Neru’s pissed.
All day today, she’s been putting out fires. Literal fires.
She doesn’t know who gave Beel and Satan the idea to try to improve Solomon’s recipes, but she’ll kill them when she does. Scooping the last of the ash into the bin, she sighs. It feels like all of Devildom is conspiring against her. Every day since starting her relationship with Mammon, there had been things to do: meetings to attend, punishments to endure, magic to learn. And even worse, the other six brothers had made it their mission to be the most giant cock blocks.
Even today, Neru and Mammon had been on her bed making out. His hand on her panties was teasing her just slightly. They hadn’t had sex in a week, and they needed this - she needed this.
But then her cell phone buzzed to life, and it was Beel asking for help to put out the large grease fire that had started downstairs. She would have ignored it if it hadn’t been Lucifer calling Mammon, demanding he come by his office this instant.
After that, she didn’t see Mammon the rest of the day. Lucifer had to have finished yelling at him by now. And there was still some time before she had to help with dinner; maybe she could find him and finish what they had started.
When she can’t find him in any of the usual places, she walks to his room. When he doesn’t answer her knocks, she assumes he’s not there. And since the door is open, she lets herself in just to be safe.
Mammon doesn’t notice that she’s there. His headphones are in; volume turned up so loud she can hear the bass. His hand is running down his exposed stomach, and the other hand is pumping his cock in quick hurried motions.
Neru’s frozen, watching her boyfriend pleasure himself. Her center begins to throb, and her mouth waters. She doesn’t even consider that he decided to start without her. Mammon tilts his head back against the pillows, his face and neck flushed deep with arousal. She feels herself getting wet. But she doesn’t want him to stop. Her hand reaches down, and she gasps when she finds herself already soaked through.
And that’s when he catches her.
“Babe, what the fuck?!”
Mammon scrambles out of bed to pull his pants up. Neru jumps and turns away.
“Mammon, I’m so sorry!” She squeaks. He’s going to think she’s a voyeur, and do demons even care about kinks? How was she going to -
“Babe, I didn’t even realize you were here,” Mammon murmurs, his arms circling her waist, “sorry you uh...saw that.”
Neru turns in his arms and sees he’s embarrassed. She feels terrible, but it was so fucking hot to watch. “What were you thinking about?” she whispers, looking up at him slowly. Mammon grips her tighter and breaks their gaze. She pushes herself up against Mammon and feels him straighten, “Mammon, tell me.”
He doesn’t look back at her when he replies, “You...”
And though she knows that’s what it could have been, hearing him say that sends a roaring flame straight to her core. He looks back at her noticing her breath is heavy. Neru’s eyes are dark, and her cheeks are flushed. Mammon smirks as he leans to whisper into her ear, “Do you want to hear more?”Neru shivers and nods, breathing out a yes. Mammon’s hands travel lower till he can grab her ass gently kneading.
“Mammon,” she sighs, “need you.” And she kisses him hard. Mammon keeps his hands on her and pulls her to the bed. She’s on top of him, kissing him, and he moans just enough for her to swipe his tongue with her own. It’s a messy make-out session, a necessity to make up for the lost time. Her hands skate down his front till she gets to his jeans, and she pulls him out. He’s still hard, and Neru moans because she is finally going to get what she’s wanted all day.
Mammon’s phone begins to blast that wretched pop song Asmo set as a prank. He’d yet to figure out how to change it, and it’s an even worse reminder that they’re not alone. She jumps back from him, and he pulls to look at it. Lucifer lights up in bright letters. Mammon groans, and a Neru panics. He’s going to have to answer it. He’s going to have to leave. And she’d be stuck again, wet and needy.
That is not happening again.
Neru rips the phone from his grip and tosses it to the edge of the bed, out of reach. She’s pressing kisses along Mammon’s neck, pulling the edge of his v neck down to nibble along his collarbone.
“N-Neru!” Mammon watches her, pupils blown wide: a dark violet. He tries to sit up, but Neru plants a hand on his chest, straddling him. Mammon watches as she reaches down under her skirt to slide fingers down her slit. A small sigh escapes her, and Mammon’s cock throbs. This is what he had been thinking about: watching her touch herself in slow, methodical movements. Taking all the time that they could never seem to get. It’s hypnotic. Neru bunches her skirt over her thighs, revealing pale yellow panties slick with want, and his breath catches. Mammon wants to taste her, no, devour her.
The cell phone screams to life again. Mammon throws his head back into the pillows. “Fucking shit! What do they fucking want-“a guttural moan cuts him off as Nehru grinds down on his length. He’s already so far gone, the friction of her panties the best distraction from his useless brothers.
“Mamm-on,” Neru whimpers, grinding down again, “Need you now.” She fingers her panties and pulls them to the side, revealing her mound pink and we. Mammon can’t keep his eyes off it. She can’t hide the feral hunger as she sinks, already perfect for him. Neru keens at the stretch of his cock inside her. In any normal situation, she’d keep still, get used to his girth inside her. But the demands of the day had frustrated her, and absence does make the heart grow fonder. Once her hips are flush against his, Neru begins a steady, rocking pace.
Mammon’s eyes roll back as he’s enveloped in the warmth of her Fuck baby just like that. Pussy so good. He knows he’s speaking praises and expletives, but even his voice feels a distance away from the feeling of velvet walls. He can hear Neru whimpering her praises. Head rolled forward, cheeks flushed red. God damn, she was beautiful.
“Neru,” he feels her flutter around his cock at her name, “Neru, baby,” She moans again, pacing faster onto him. Mammon growls and reaches to catch her hips. “Ya gotta stop, baby,’ he chuckles, “it’s too good.”
She doesn’t stop.
Neru bounces up and down her thighs, burning lost in the churning of her pleasure. Watching the way Mammon’s eyes roll back and relishing in the way he grips her hip: nails digging into her flesh.
“Fuck - Neru,” Mammon is pleading a mess. She can feel him tense under her. He wouldn’t last much longer. Neru catches his eyes and smiles.
“Let go, Mammon,” she whimpers, and that’s all it takes for him to release and release and release into her. He shudders and gasps, and Neru feels herself fluttering around him, clenching tighter as she milks him.
He finally has the wear with all to hold her still. He groans with a twitch and then breaths a heavy sigh.
“Fucking shit, woman,” he curses, holding them still, “that was -,” he huffs, “wow.”
Neru smiles at him, eyes still glassy with lust. Mammon’s entranced by the flush that starts at her cheeks and disappears down her neck into her shirt. He gains enough strength to push her off with a whimper, gently maneuvering her to the bed. He crawls over and litters kisses across her forehead, cheeks, and nose. Never in his eternity of living did he think something so beautiful could be his. Her giggles lit his heart aglow. And maybe it was that after sex rush of emotion, or perhaps it was because it had been too damn long.
“I love you,” he whispers.
A different heat blooms within her, and Neru smiles softly, reaching to caress his warm cheek, “I love you too,” she’s said it a thousand times, but he can’t get used to the gentle declaration. His face heats up in embarrassment, and he hides it under the guise of kissing her chest and stomach.
“Fuck!” He grumbles, “you’re just so fucking - Fuck I -“
Neru giggles, ready to tease him, but then she hears the distinct rip of her panties.
“Mammon-!” Mammon shoves her knees up to her chest, and she squeaks. He positions himself in front of her center and meets her eyes, cheeks still flushed.
“You’re just so fucking cute,” and he steals her response by licking a stripe up her center. Neru clamps a hand over her mouth, muffling her gasps. Mammon moans in satisfaction, tasting his release mixed with her juices. His tongue scoops himself out of her; he can’t get enough. Neru’s thighs are already tense and shaking in his hands. He glances up through long eyelashes to find her watching him. Hand still over mouth, face beet red, chest rising up and down faster now that she catches his gaze. Mammon hums around her and flattens his tongue against her clit. Neru arches her back, a high-pitched moan escaping her lips.
He smirks and continues his ministrations, eyes closing in fervor. He would devour Neru like this forever if he could. She was too sweet for anyone else but him. He was her first, and he’d be her last. Neru’s pants were becoming louder like she did when she was close. Mammon didn’t want to stop. Didn’t care if she was going to be over-sensitive. Her pleasure triggered his greed, and he needed -
“Mammon!” the pounding on his door breaks him of his trance. Neru tries to pull away as Lucifer’s voice calls for him again, “Mammon, you have not yet explained this bill from the other day.”
Mammon looks from the door to his girlfriend, who is very clearly ravished and looking very unsatisfied. His grip had weekend against her, and when Neru looked his way, she smiled a sad smile: a, we’ll have to continue this another time, smile.
“No,” Mammon growls, and when Neru continues to move, he grabs her legs again, “I said no.”
She tries to object, but Mammon pulls Neru flush against him, arms wrapping around her thighs and over her stomach. His lips immediately find her clit, and he begins to suck on the bundle of nerves, eyes never leaving hers. At once, she’s back on her climb. Neru tries to push him away, but they both know it’s fruitless. Her face is flushed, the brightest it’s ever been, and he’ll have to ask if maybe she’s got a slight voyeur kink.
Neru’s moans and pants get louder. She’s chanting his name, almost sobbing it. Her stomach tightens, and she doesn’t want to come when Lucifer can probably hear them on the other side of the door. But Mammon’s pushing her to a place she can’t come back from, so far that the logical part of her gets smaller and smaller till all she feels is his lips on her.
With a final suck of her clit, Neru spasms against him. Her mouth opens in a silent cry, eyes rolling back. He works her through her orgasm as she finds her voice. Hiccuping his name until finally weakly pushes at his head, signaling no more. Mammon gives her one final tender kiss before pulling away. He can feel her on his lips and chin, and he so wished he could go back and savor more.
“Now that that’s over,” Lucifer calls irritation thick in his voice, “I still need to speak to you, Mammon.”
“Conjugal visit is over Mammon!” Asmo’s voice calls sweetly, “but thanks for the show.”
Mammon throws a pillow at the door, shouting, shut up! He looks at Neru, who is very clearly embarrassed, but she can’t help a giggle that turns into a burst of laughter. He glares at her and tries to duck back down to her, but she holds him back.
“Down boy,” she teases, still breathless, “we’ve still got work to do.” Mammon licks his lips and climbs over to kiss her deeply.
“Fine,” he grumbles. He kisses her again, nipping her lip lightly, “but maybe we should consider getting a place for ourselves.”
