#leviathan.om!

finding out leviathan has an ovipositor & just immediately pouncing on him to get stuffed with eggs..

I get the distinct impression it would all be Asmo's fault in the beginning, lol. He not-so-casually lets slip that Levi has some... Unusual anatomy, urges, mating habits... Specifically to pique your curiosity and get you to ask. Levi wants to melt into the floor, poor thing thinks you'll be grossed out by him and his weird dick, not to mention that he lays eggs in his partner if it's that time of the year! But Asmo knows better lol, he can feel the little flicker of lust in your heart as you stare at Levi, shamelessly squinting as if you could see right through his clothes.

Man I bet it would feel sooo good to have his nails dug firmly into your back as he cums, shaking and whining, crying a little every time one of his squishy eggs pops out of his cock and directly into your womb... And he still has to cum in you again to make it stick!

I can't stop imagining the om! universe having minimal crossover between realms when it comes to fandoms, so something you might consider fairly mainstream is highly niche amongst demons. Anyway all of this is because I'm thinking of offhandedly referencing JoJo's or humming a vocaloid song in the house and Levi looking at you like you've grown a second head because only him and 3 other demons have even heard of Miku. Imagine how lovestruck he'd be (and a little pissed off maybe bc you're so knowledgeable and he thinks it makes him look bad).

oooo~

share all your headcanons ;)

Yes ofc sorry for the delay! Have some thoughts in relative order (and again please check out this fic)

Lucifer: To me Lucifer has the picture perfect dick. YA novel male love interest dick. 6 inches long and thick enough that he has to finger you open for a bit before going in, and you can see how much he likes it. Always has an annoying little smirk on his face when he makes you cum around his long, slender fingers. He's prone to degrading you during sex but honestly that's to be expected, fucking you feeds his ego like nothing else. He's not a fan of showing you off or public sex in general though (that's Diavolo's thing), likes to keep you to himself instead.

Soft sex is possible but he has to be feeling mushy beforehand, like from a date. Lucifer usually prefers to take his frustrations out on you during the act and saves the gentleness for later, when he runs you a hot bath and washes your back.

In his demon form not much changes, except he's proportionately bigger and meaner. His cock grows stiff, fleshy ridges along the underside and he loves the noises you make when he fucks you from behind and they rub against your insides. The biggest differences are him biting you all over and fanning out his wings to cover you both, simultaneously shielding you from the outside and preventing your escape. Grab his horns for support, he loves it.

Mammon: My sweet Mammon, my perfect boy. His cock is short but abnormally thick, to the point where penetration is almost not worth the hassle. He distracts you from it though, always kissing you and groping you while he humps his cock against you until he finally nudges inside. He always whines so prettily when you squeeze around him, it's so obvious he's in love with you. Mammon fucks hard and fast, desperately chasing his next orgasm while simultaneously trying to wring one out of you. He'll do and say anything practically anything to get you off, just please let him hold you close and finish inside you.

In demon form he's always half hard, ready for you to drag off to a secluded corner for a quick fuck. You can rile him up anytime but it gets ridiculous when his horns and wings come out. His cockhead grows pointed and a fat knot appears at the base of his already thick cock. He gets touchier than usual and purrs, or messes with your hair/clothes as a way to preen you. Imo he frequently proposes cockwarming bc he wants closeness, but always ends up getting needy and fucking you.

Leviathan: Well it's been said before but Levi has two cocks, period. The one on the top functions as a human's would and the bottom one is reserved for laying eggs. They'd both look fairly weird, I see them in my mind as those alien themed dildoes with strange shapes. They're always slightly cold and produce copious amounts of clear slick instead of normal precum. In his demon form I'm not sure what would change... his skin would be coloured differently, maybe blueish-grey or scaly. His ovipositor probably bulges and becomes more noticeable, as opposed to his human form where it's not that visible.

leviathan.. getting somno'd by leviathan because he just loves you too much and wants to feel your wonderful body, but "knows" you'd never want a creepy perverted otaku like him...

Oh gosh yes please he's so cute... Pathetic little baby who pines over you for weeks and weeks, jerking his big leaky cocks to porn he makes of you or characters that look like you, he even jerks off in his bathtub at night while you sleep on his couch only a few steps away, that's how badly he needs you. You're so bright, so wonderful, you've made everyone fall in love with you and Leviathan is no exception of course, but he knows he doesn't have a chance. You're being courted by Lucifer, for fucks sake, you're not even thinking about him. Shy, quiet, mean, awkward Levi who stumbles over his words when you smile at him and goes off on rants about animes nobody cares about.

You care, though. You pretend to anyway, Levi has already convinced himself you only do it out of pity. He enjoys your company regardless, and having you asleep in his room is the perfect opportunity to collect risqué pictures of you. Sometimes, when he's tired enough and the lights of his tank are turned low he can almost delude himself into believing your smiles are genuine.

One of those nights, when you fall asleep on his beanbag, he doesn't carry you to your premade bed on the sofa. He sits on the floor and watches you snooze away, your head tilted back at a weird angle and your shirt riding up slightly over your hip. You trust him so much, too much. Leviathan is a demon, can you really blame him for taking what he wants?

You're so wonderfully soft and hot under his hands, perfectly pliant and unaware, spread out just for him even if you'll never know it. Levi fucks you first with care then with pure abandon, crying from the sensations and the guilt of what he's doing to you, but he just feels too good to stop. You're basically made for him. And Leviathan has spent so long thinking about this moment, imagining different scenarios.... He might run out of time this night, but there's always the next.

ohhh Levi...

imagine having him dress up in whichever cosplay of his has the shortest skirt, and putting a pleasantly tight collar and leash on him... making him hump your leg like a dog, his flushed face looking extra pathetic with slight tears in his eyes and saliva on his lips...

if he's extra good, let him fuck your thighs from behind in doggy style while whining in your ear, his inhuman cock(s) twitching against you as they drag against your underwear...

make him beg to cum, before finally allowing him, then pushing him off to shove his face in-between your legs and eat you out with his long forked tongue...

tell him to use the gorgeous mouth of his as best he can, because it's the only part of him other than his fingers that you want in you... how much of a gorgeous little slut he is... watch him eagerly grind against the sheets at the degrading praise...

Fuck Levi is so cute I wanna spoil him. He looks so cute rutting his little cocks against your leg with tears in his eyes, the edge of his skirt held in his mouth to give you a good view. Rutting between your legs and leaking so much that your underwear ends up soaked, Levi almost in tears from humping the rough fabric instead of your soft skin. The cloth isn't even that bad he's just that sensitive and overwhelmed, he can't believe you're letting a gross otaku like him get himself off against you.

And of course he wants to service you. Levi might look weak but he can take a beating, and he doesn't mind choking a little if it makes you feel good. He'll hump the air and beg for your touch, keeping his hands on your thighs to make sure you don't get up, throating your cock or burying his long tongue in your cunt, you can practically see the stars in his eyes.

Been thinking very hard about Levi in a cat maid dress after remembering he has canonically been interested in dressing up as one. Also been thinking about fucking his thighs while making him hold his skirt up and calling you master

Levi having not one or two dicks but a whole mass of tiny writhing tentacles like an anemone. Send post.

So sometimes when I sit and study for a hot sec, I can’t sit there the whole time/feel myself lose attention and occasionally will take a step back and get myself to cum and then continue

This originally started as a joke to myself cause I was like damn imagine if this made everything better, but then it ACTUALLY did and I find myself doing it whenever I have a lot of studying to do and after finishing the studying I had planned for tonight all that’s on my mind is men who would happily assist me in cumming before I go back to studying.

The first one that came to mind was Dazai, because that man with zero hesitation would basically become your dildo and let you ride him till you cum and then you continue working. He probably gets off to the fact of you using him like a toy and even if you aren’t really trying to please him, I feel like he’d probably somehow manage to cum untouched just sitting there after you cum and return to your studying

I also feel like Levi would 100% accept it too. He whines the WHOLEEE time asking about when your next break is. He probably brought a handheld game with him to play while you study but after the first time you use him he can hardly pay attention, his cocks twitching waiting for you to come back :(

Tho I will say as someone who LOVESSS Nikolai I feel as tho this would not work with him. He’d probably go along with it at first but he’s just so much bigger than you that if he wants to keep fucking, even after you cum, he’ll keep you there. Oh? You wanna return back to studying? Sure! Let him just move both of you into your chair so he can stay with you. What do you mean you can’t focus with his cock in you? Aren’t you the one who was practically begging him to help you cum while you study?

This whole image is now going to be haunting my mind for the rest of the night so I’ve now sent it to your mind as well

Soooooo guess what I should be doing instead of answering this lol

Fucking hell tho that's a big lifehack, of course you'd take advantage of it! Dazai would love to be used like that but he'd probably get whiny when you try to go study, are you sure you don't need another little boost? Not sure if you'd get anything done, you might need to throw him out of the room or cockwarm him to get him to sit still and stop bothering you.

Nikolai is hands down the worst choice. He's very happy to help! .....A little too happy to help. Yeah, it's been 3 orgasms and he's still got you pinned to the bed with his whole bodyweight. You're not going to study today.

As for Levi..... poor thing, he can't take it. You have to convince him that yes you're serious, no this isn't a prank, no you're not laughing at him, yes you do want this, yes for real, yes you promise. He squirms all over the place and can't even look at you, cumming with a loud, embarrassing moan and then hiding under your covers for half an hour trying to live it down. But once his brain finishes rebooting he's going to get impatient, his cocks twitching with interest when he peeks at you, hoping you'll want his help again. He gets hissy when you tell him no, not now. All your pleading and your reassurance that you wanted him, and now you're ignoring him? Absolutely not!
