Haunted Cat Nerd

You remained in your demon boyfriend’s arms, scrolling through your phone, looking at social media. Mammon watched with you, telling you to scroll back up and click on things after you scrolled past them, making you playfully scold him. He kept on doing it, laughing at your reaction and trying to fluster you more. It wasn’t until you heard a ping from Mammon’s cell that you put your phone down.

“Aren’t you gonna check that, hmm?” You exaggerated your tone, lacing it with sarcasm.

He huffed and lifted it to his face. “Nah.” He then put it back down and put his arm back around your waist.

“What if it’s important?”

“It’s just Asmo, probably something makeup or fashion related.” He shrugged.

“Okay, you’re probably right.” You returned to your social media before you also received a message from Asmo. “What the hell?”

You opened it and read: ooooooooh~

You typed up a message, disturbed by the vagueness.

Mc: Huh?

Asmo: hehe

Mc: what???

Then no response. Mammon’s DDD rung again. And then two other pings followed. You turned to him, making him groan.

“I was comfy, ya know!”

“Get your DDD and figure out what’s going on.” The pings continued, equally frustrating and worrying the both of you. Mammon opened his DDD and went to the group chat shared between his brothers and then his eyes went wide and his jaw dropped open. He went pale and you started to panic. “What is it?” You pulled his cell to your eyes and saw immediately what it was.

Asmo: guys look! *sends video*

Asmo: they make such a good couple! I’m so happy they’re compatible in all forms! I gotta say I’m a little jealous!

Levi: JADNFJRNFJNRNF

Satan: no fucking way

Beel: ☹️

Asmo: I know, who would’ve thought Mc was that nasty! Wait until 23:42 where they take him into their mouth right after he pulls out of them!

Satan: all I needed to see was the thumbnail. No thank you. Mammon’s little mammon isn’t something I’ve ever wanted to see.

Belphie: I got about 2 minutes in, they already have spit everywhere even though they’re just making out. So dramatic.

Asmo: I think it’s passionate! Romantic! And messy. Our little Mc clearly isn’t shy when it comes to spit! They let Mammon spit in their mouth at around 7 minutes.

Beel: I can’t watch. Please stop telling us what happens.

Asmo: but I didn’t even tell you the best part!

Belphie: if it involves Mammon I don’t want to hear it

Satan: how can it not involve Mammon?

You and Mammon remained frozen, watching as more messages filled the chat. Levi remained silent and, rather terrifyingly, Lucifer remained absent from the chat. Mammon prepared to type a message and then you stopped him.

“There’s no point. Only Asmo and probably Levi will watch it at least.”

“At least!!! Mc! They have no right to be able to see you like that!” He sat up and started typing.

“Uh! Obviously! But typing something will only egg them on, you know that! Plus what about Lucifer!” You tried to reason with him, sitting up beside him. “And the even bigger worry is how the hell did Asmo find the video! It’s on my DDD!” You showed him where your messages were still open with Asmo, clearly not showing any sign of you sending the tape. Despite you telling him not to, Mammon started typing.

Mammon: HOWD YOU GET THAT!

Asmo: I found it

Beel: you didn’t send it?

Mammon: NO!!! WHY WOULD I SEND THAT??

Asmo: it just appeared in my videos one day. I’m not sure how but I’m not upset. Did you not want us to watch it?

Mammon: EXCUSEEEE MEEEE???? NO! MC IS NAKED AND DOING A WHOLE LOTTA STUFF! AINT NO WAY I WOULD DO THAT OR THAT HAPPENED!!!

Lucifer: A sex tape?

The both of your hearts skipped a beat.

Lucifer: A sex tape that magically appeared in Asmo’s phone? Did Mc send it? Mammon is clearly too possessive to willingly send a video of Mc naked and “doing a whole lotta stuff” for lack of better terms.

You both heaved a sigh, thankful he didn’t immediately lecture you both.

Asmo: could’ve just been fate.

Mammon: Mc didn’t send it! Lucifer, you gotta figure out what Asmo did!

Levi: current status: 5:14. Mammon asked Mc “you’re already desperate, huh?” Directly after Mc said they were desperate for him. Mammon is clearly a little behind.

Mammon: STOP WATCHING

Lucifer: I will figure out what happened. However, Mammon and Mc, you will need to realize that for evidence, I will likely have to watch it.

Mammon: WHAT

Lucifer: who knows what happened, Mammon. Asmo could’ve snuck in when you didn’t notice and cursed your DDD.

Mammon: NUH UH! I’ve watched that video over and over, ain’t no way.

Lucifer: seems as though you’re the desperate one then, hm?

Lucifer: also, to clarify, I won’t exactly enjoy seeing your little Mammon either. Would you rather me send it to Barbatos to figure out what happened?

Mammon: you know what, I don’t even care. Just.

Mammon: Don’t.

Mammon: Watch.

Mammon: IT.

Lucifer: You know what, I’d rather leave this be as well. Everyone needs to have this video deleted from their library. I will be inspecting everyone’s phones to make sure it’s not there.

Mammon: WHAT

Levi: NOOOO

Asmo: okay well don’t be surprised by what you see

Belphie: this government (Lucifer) is too oppressive.

Satan: what will Mc think? Going through her phone? Personally, I think we should overthrow our government (Lucifer).

Beel: I don’t have anything to hide. Just don’t judge me.

Mammon: I’m leaving the House of Lamentation. Nah, the whole Devildom. You’ll never see me again.

Lucifer: 👍🏻

The two of you looked at each other, defeated and deflated. Both of you, hunched over, staring at the messages flying across his DDD. While you wanted to figure out what happened, you just accepted that it’s better not to probe. Needless to say, you were also encouraging of Mammon’s idea of a vacation from the Devildom, not necessarily a permanent one.

The two of you did not leave your room for at least 24 more hours. You just didn’t want to deal with it. However…

Asmo to you privately: want some ideas?

Maybe this wasn’t entirely too terrible.

“Ass or tits?”

Lucifer: “pardon me?” Cannot believe his ears rn. But tbh a tit man. Likes them average sized ones too, that just perfectly fit in his hand

Mammon: “mmmmmm….personality😝” I don’t think he has a preference, like literally. He just likes your body😭

Levi: turns as red as a tomato “WHY WOULD YOU EVEN ASK ME THAT?!?” I mean come on….. we all know he’s a thigh man. Don’t matter if they’re small, average or large. Just thighs

Satan: just laughs at you, then answers nonchalantly “I actually prefer collarbones” cuz he’s some kind of fucking weirdo like that

Asmo: “hehe pussy” will not ever answer the question and then will beg for 20 minutes to eat you out, even if ur in public…lil creep

Beel: “on a chicken or on you?“ he’s a booty man. Again doesn’t matter how big or small (though he does love it when his partner is smaller than him…ahem… size kink)

Belphie: just calmly says “boobs” as he’s literally laying down on them. They make good pillows

Diavolo: looks at you like a confused puppy and answers with something like “I like it all when it comes to you” he truly doesn’t have a preference tho. Though he’s the same as Beel (size kink) loves seeing his dick-print during your activities….

Thirteen: “ohhh baby you know I like it all” though she will spend a very long time sucking on your nipples until you can’t take it anymore

Hello anon 🌻🌻

Loves cumming on your face, he thinks you look so pretty looking up at him with your mouth open covered in his cum.

Needs to watch you pleasure yourself, he caught you fingering your little hole while in his bed. He came home early from a shoot and found you wearing one of his shirts and nothing else, legs spread wide, fingers pumping in and out. Drives him wild, even wilder if you don't let him touch you right away.

Hates smelling other demons/angels/humans on you, he can make an exception for his brothers most of the time. But anyone else no way.

Doesn't like it when you side with one of his brothers over him, even if he is in the wrong. You're supposed to be his human, why can't you be wrong with him?

Hope you liked them sweet anon 💕

Let me know if you want more, I'm enjoying writing these 😘☺️

For the event: I think about Mammon who is very horny, but feels guilty about it because MC looks too innocent. Some kind of hurt/comfort? Then it turns out that MC is pretty horny too ~

Mammon really struggled to stop himself sometimes. At least when it came to his urges, whether it was his greed or something else. Throughout knowing you, he’d always find himself feeling so strongly for you, the urge to touch you and make you his, but he knew he must wait for you to let him. So he’d take to touching himself, rubbing out one every chance he could.

It wasn’t until you two were together that he finally felt comfy with expressing himself around you but there was one thing that he could never tell you. His thumb would hover over send each time he wanted to send you something dirty but he would always delete the message. When you were nuzzling into him mid-cuddle and your bottom would brush against him, he’d tell himself not to say anything and wait.

After all, humans like you were so innocent! He remembers back when he last went to the human world, sex was so taboo! It was all missionary and in the dark under the blankets. Sure, he knows things have changed, he’s watched plenty of human movies, and listens to human music… but that’s not you. Everybody is different right? He’d be… defiling you, almost. Plus, no human can compare to a demon’s horniness!

You, on the other hand, thought completely different from him. Society is changing and so is the view on sex, so is the view on how much sex and how kinky the sex is. You wanted him, really, really bad. It was so hard to tell him, especially since each time you’d get ready to make a move, he’d shy away and avoid it. Did he not find you sexually appealing? You definitely found him sexy! You wanted to ask him outright what the issue was, but what if he just confirmed your assumption?

You’d brush your bottom against his crotch, waiting for a response, just for him to reposition and not respond. You’d start a conversation around sex and he’d be quiet or completely miss the point. It had gotten to the point that you were just desperate. And now that you’re situated on top of him, tongue in his mouth feeling him up and down, you know exactly what he’s going to do.

“Mammon, I want you.” You huffed as your mouths separated.

“Mm.” He continued to kiss you, his only response a grunt.

You pushed him away. “Do you want me?” You looked at him, his eyes wide and flitting away.

“Yeah.” His response was quiet.

You felt your stomach sink and you looked down trying to hide the tears forming in your eyes. He looked back at you and saw the change in demeanor.

“What’s wrong?” You looked away from him, trying to swallow the lump in your throat. His heart was beating like crazy. “Mc?”

You nodded. “I’m fine.” Rushing the words out as fast as possible. “It’s okay, I just need to get up.” You left his lap and rushed to your room, leaving Mammon alone on his couch. He watched you leave, wondering if he should follow you.

You settled in your room and sat with your back against the door, holding your knees against your chest. You didn’t know if you wanted to cry or not, to let all the emotions fly. Your phone dinged.

Mammon: did I do something? Whatever I did I’m sorry I didn’t mean to upset you please Mc.

You looked at the message and tried to think of what to say.

Mammon: I’m really sorry.

Mammon: can ya say something?

You tentatively moved your thumbs over your screen.

Mc: am I not attractive to you?

Mammon really couldn’t believe his eyes when he received the message. Are you kidding?

Mammon: ain’t no way that’s the problem. You’re more than beautiful. Might as well take Asmo’s place as the prettiest in the Devildom.

You felt flattered but that wasn’t what you wanted to hear.

Mc: why do we only ever just make out?

Mammon: wdym?

Mc: I want to know why don’t you touch me or you know

Mammon’s heart skipped a beat, he stood up from the couch and started to walk your way, still texting.

Mammon: I do want to touch you. But I never think you do.

You felt your lip quiver.

Mc: I always want you.

Mammon knocked on your door. “Can I come in?” You stood up in front of the door hesitated before letting him in. He came face to face with you, little tears coating your face complemented by your puffy eyes and strained face. “Mc, I’m sorry I make you feel that way.” You wrapped your arms around him, both so he couldn’t see the tears in your eyes and to also get that comfort you desired.

“It’s okay.”

“No, it’s not. You shouldn’t ever feel unwanted. Or undesirable or whatever.” He kissed your neck, not in a sexual way but in an ‘I love you’ way. “I’m obsessed with ya, in every way. Yer friggin’ perfect.”

You continued to hold him, not wanting to pull away. You tried to calm your emotions and let the tears remain in so you could talk to him.

He could tell you were trying to calm down. “I’m sorry I never do anything. I always think that—that you—well, I dunno how to explain.” He was struggling to find a way to explain your assumed innocence. “You seem so innocent. So humanly.” He settled on that. You found yourself confused by his words.

Humans! Innocent!!??? Does he know anything about humanity?

You actually laughed a little, confusing him. “Why’re ya laughin’?”

“Humans are so not innocent.” You couldn’t help back let go to get a look at his face, which was was just the way you expected it. Dumbfounded. “Jeez, you demons and your assumptions about humans. I don’t know a single innocent human. Do you just think we are a bunch of Lukes running around?” You were now really laughing especially with his newfound face. He looked almost like a… fish?

“No! I just… okay.” He sighed and breathed in sharply. “Let me just get it out. I didn’t think you were as horny as me. I still don’t. Demons and temptation, ya know.”

“Mammon, that makes no sense. The average human has a sexual thought every few minutes or seconds or something like that. We literally have 100 year lifespans we sorta are inclined to always think about sex. And you demons, millennia long lifespans. You don’t have to have babies 24/7.” You weren’t crying at all anymore and now Mammon was absolutely in shock.

“Every few seconds!!! No way!! Uh uh.”

“Let’s look it up.”

Mammon shuffled through his ddd and then plastered his phone in your face. “Told ya. It’s 19 times a day.”

“Uh, Mammon, it ranges from like 19 to 388.”

“Only in men!”

“Well I probably think about sex with you about 388 times a day.”

“Pssh. Then I’m probably in the thousands.”

“No, Mammon you don’t think enough for that.”

He wanted to say something but he ended up just looking at you. You could tell all that tension from earlier was already making a return at least for him.

“You okay, now?” You nodded. “Let’s go back to my room.” You nodded again and took his hand. When you got to his room, he got red and stopped in his tracks. “You wanna have sex now?”

“Mammon, didn’t we just talk about this? If you reject me now, I’m never looking at you again.”

He grinned and licked his lips, pulling you into his room by the waist. “Clearly, we have no choice!”

I am such a nervous wreck but I feel like Mammon would coax out my inner hoe. Like I was just thinking about grinding up on Mammon nice and slow making him blush at first and go crazy. But now… in a public setting??? Oh yeah he’s gonna show tf off.

You’re pressing your ass into him, throwing it back and he’s eating 👏🏻 that 👏🏻 shit 👏🏻 up!

He’s got his arms up, throwing back some demonus, letting you do your thing and making sure everyone is watching. Then as you straighten up, he grabs your hips and grinds against you in rhythm with the song, telling you how sexy you look, how he can’t stand that other people can see you like this, but goddamn is it hot that they know that you belong to him and him alone.

He’s definitely biting your ear, nibbling your neck, feeling you up and down, hands tugging and pulling. Man, he cannot fucking wait to leave and fuck you nice and long, making your pretty little head go crazy, coaxing out all the praises he can while you tell him that you belong to him. He’s thinking about everything you’re gonna do later and he’s getting the most painful hard-on he’s ever gotten.

“Hey, you hear that?”

You slapped your hand over mammons mouth and the two of you froze.

“Hear what?” Another voice rung out.

Mammon looked at the shadows of footsteps through the light under the door of the private bathroom. You could feel your heart racing even more than it was while Mammon was lifting you up and down like you were weightless while your pussy clenched him like a glove. Mammon’s was as well, you could feel each others pulses considering how tightly you’re slammed together.

“Could’ve sworn I heard someone groan like they were in pain.”

You moved your hand and Mammon spoke. “Hey, you aren’t in pain, right?”

“Dummy, they’re talking about you! Plus wouldn’t you know by now?” You whispered back, squinting at Mammon and feigning anger, but failing.

“Yeah, you did silence me. Shoulda done it like this though.” Mammon planted his lips on yours, sucking at your bottom lip and biting.

“Mm!” You moaned into him, wriggling to feel that same friction you had earlier. Mammon hummed into your mouth, a cadence of a laugh vibrating through him.

You felt his hands reposition under the flesh of your ass, preparing to bounce you back on his cock. You had your legs wrapped around him while he stood upright with you almost against the wall. He moved his head for a second and went back to attacking your mouth, trying his hardest to quiet his groans through you. Mammon lifted you up and down with ease, his demonic strength always showing when it’s convenient for him. Or you for that matter.

Your hands ran through his hair before reaching underneath his clothes to touch his bare back. He felt phenomenal in the way his cock just bullied your g-spot over and over. You couldn’t bite back your moans so each time you had to stop to breathe, you buried your teeth in him, which, in turn, made Mammon’s groans that much louder. He struggled to hold them back, why should he since you feel so fucking good?

His brows were furrowing and his teeth were clenching while he squeezed his eyes shut, almost as if holding back his noises were painful. You bit down on his shirt after realizing biting him wasn’t going to help, but it’s not as though the thin fabric would either. You knew you both should stop, but you were so close and it was so good. Mammon was already in you and having that sense of danger only fed into his primal instinct. To fuck you and make you scream for him so everyone could hear. But also, why should they be blessed to hear your beautiful cries for him? You could say he was truly fighting demons, his demon for that matter.

You were so wet and wearing that cute little skirt with no panties today was dangerous, but to tease Mammon throughout the day was far to tempting. To take his hand and let him feel you was the highlight of the lunch hour. The way his face went red and he blabbered protests was almost too cute to watch. And then when he sat your panty-less self on his lap, to the chagrin of his brothers, and started to palm at your bare clit… you knew you had to cum right then. But in front of everybody, oh, Mammon would never let them see you so vulnerable and pleasure drunk no matter how hard you tried to hide it. So you found yourself in the nearest bathroom directly outside of the lunchroom getting dicked down like some little human desperate for some demon cock.

Mammon loves to see you begging and desperate for him, but he can’t handle it. Teasing him is always such a pain for him since he gets so wound up so fast. He might want to play your game, but he can’t handle it. He wants to abandon all control and pound into exactly how you want and need him to. Feeling your wet little pussy during lunch sent him, truly. Damn, if there weren’t so many people, he’d have you on the table ready to devour your dripping cunt. He’d spread your pretty legs and put them above your head, giving him all the access he can get. He’d shove his tongue so deep that’d you’d be convinced it was longer, then he’d suck your clit until you were pulling so hard on his hair that it might come out.

“Mammon I’m cumming!” Your hold body tightened around him, desperate for whatever leverage it could take, but to bear hug him while practically milking him with your squeezing pussy made the both of you cry out. You slammed your face into his shoulder, muffling whatever you could, but you couldn’t help but say his name over and over. Mammon was close, but he didn’t even consider where the hell he’d cum.

He pulled out last minute and ejaculated on your entire lower region. From ass, to pussy, to thighs. He came with a growl, not as loud as your name-calling, but the moans following afterward and the “oh fuck!” Was enough to seal your fates.

After cleaning your cum coated legs and wherever else his cum might’ve landed, the two of you prepared to face your doom. Mammon suggested the two of you wait until lunch ended, which you did.

However, you never know who might be on the other side. Or rather, where.

Mammon swung open the door with gusto just to find Lucifer staggering back on the other side.

The common room. When everyone is asleep or when you’re feeling extra risky.

His pool table. Yeah, he tries to bend you over each time he goes to play.

His couch. Well, you gotta watch movies. So almost every day if he could.

The bathtub. Very risky since they share it with everyone but Asmo. Only when you’re the only ones home.

A RAD classroom. Anytime he’s extra horny.

The RAD bathroom. Anytime he’s uncontrollably horny.

At a club in a private room. Each club visit.

In the garden. When it’s a pretty night and it’s warm, oh yeah. Nice and animalistic for him.

On the roof. Same as the garden but more romantic.

Pretty self explanatory.After seeing how well Thirteen's headcanons were received, I decided to give my best boy his own as well💛💛💛
