Do u have a master list? I've been looking all over your vlog but I can't seem to find one...

Heyo! Unless somethings bugged, my masterlist should be right at the top of my blog, as a pinned post :)

Here's the link for it just in case!

[demonsandco]

HI I JUST WANNA SAY I SPENT 30 MINUTES LOOKING FOR YOUR BLOG BECAUSE I LOVE YOUR IDEAS SO MUCH BUT I FORGOT TO REBLOG THE POSTS BUT I'M SO HAPPY I FOUND YOU I LOVE YOUR BLOG ♥

[mothmothmothmothmothmoth]

@demonsandco

The boy!! He looks very scary but I just want to hug him and pet his mane!!

[demonsandco]

Aaaa I can’t believe I didn’t see this earlier!!

[mothmothmothmothmothmoth]

I'm using @demonsandco demon designs to practice my inking because they look cool as hell!!

[mothmothmothmothmothmoth]

@demonsandco

I love your demon form designs!!! And I think they deserve kisses so I drew my Mc Vala with Beel and Barbs <3

[demonsandco]

Are you ok with fanart of your designs?

Of course, go ahead! Please do tag me if you end up posting it, though, because I'd love to see it!

[demonsandco]

I just wanted to say that your angel/demon form art is incredible! It is beautiful. Have a nice day/night

Aaaa thank you for the kind words!! Have a nice day/night yourself <3

[demonsandco]

Finally! Lucifer’s demon forms! As much as I like his canonical wings, I firmly believe that he deserves more pretty/flashy peacock vibes. I like to imagine that the colourful bits are reflective like actual peacock feathers, changing colour and vibrancy depending on how the light hits him

Maybe some sleeping hcs for the brothers? +what sleeping by them is like?

I like to think that they all sleep in their demon forms, both because it's more comfortable and because maintaining a human appearance takes effort.

Lucifer

Lucifer's massive bed isn't just for show, and on the rare occasion that he actually makes it to his room, he takes up the entire mattress on his own. His wings make sleeping on his back uncomfortable, so he usually rests on his front, with his wings stretched out far enough to drape over the entire bed. Typically, he's a fairly calm sleeper, rarely making noise or shifting around, but he does somehow manage to always tangle his blankets around his legs and accidently kick them away.

He's more considerate of how much space he occupies when he's with a partner. He'll often sleep on his side instead, and spoon them against his chest in a gentle hold. His wings will still end up spanning over most of the bed, stretching over them like a feathery blanket. Unfortunately, he still manages to kick the blankets off, but his natural warmth and big wings are more than enough to keep them cozy and safe.

(cont under the cut)

Mammon

Mammon is an absolute disaster of a sleeper. He always falls asleep before he means to, often causing him to end up only half undressed and sleeping in whatever clothes he wore that day. He usually ends up sprawled on top of his blankets because of how much he moves around, constantly shifting into different, yet equally strange positions. His morning routine is more like a chaotic scramble because of this, and the fact that he always forgets to plug in his DDD doesn't help.

Sleeping with a partner involves a lot of skin to skin contact for Mammon. He loves to cuddle, and while he tries to act casual about it when he's still awake, in his sleep he'll press himself as close as possible to them, almost as though he was trying to meld into their skin. It's too embarrassing for him to voice it out loud, but he loves to be spooned, or just held securely in general. He sleeps much more calmly like that, but he does still manage to shift into the most uncomfortable positions to get closer to them, usually trapping them under himself in the process.

Leviathan

The bathtub in the middle of Levi's room does actually serve as his bed, but the many blankets lining the sides makes it surprisingly comfortable and warm. He prefers to sleep curled up into a little ball with his tail wrapped tightly around himself, completely hidden from the outside world. He rarely shifts from that position at all, hardly ever moving in his sleep. Every once in a while, he can be found passed out at his desk or sleeping sitting up with his headphones on and his DDD slipping out of his hands.

While he's not the cuddliest demon while he's awake, Levi is an absolute fiend in his sleep. Part of it is him unconsciously seeking affection, but it feels like he's also trying to leach his partner's warmth out of their body. He always finds a way to press his cold hands against their bare skin and wrap himself around them, tail and all, like an octopus. Once he's snuggled up to them, they will absolutely not be able to remove him without actually waking him up.

Satan

More often than not, Satan can be found sleeping sitting up because he lost track of time while reading. It happens concerningly often, and he always regrets it in the mornings when he wakes up sore and not at all well rested. When he does actually make it to bed, however, he'll usually sleep on his back, completely unmoving. He feels the most comfortable when he's wrapped up in his blanket like a burrito and, while he's unaware of it, he snores very softly in his sleep.

The first thing his partner will learn about sleeping with Satan, is that he's a complete blanket hog. Luckily for them, he's shockingly warm and very cuddly, easily making up for blanket stealing. He likes to wrap an arm around his partner and hold them close to his side. He's especially happy if he can lay his head on their chest, finding the sound of their heartbeat soothing. He never does it on purpose, but they'll always wake up with his tail curled up carefully around their leg, holding them close.

Asmodeus

Asmo is the only demon in the house that has a proper sleep schedule, as long as he's not going out. His nighttime routine is important to him, and he has a hard time falling asleep if he doesn't complete it. Once he's in bed, though, he falls asleep fast, all splayed out on his back, his wings fully stretched out. His bed is so soft that he practically sinks into it, looking impossibly comfortable. Sometime in the night, he always manages to shift into a tiny little ball, curling up into the fetal position under his covers, tucking his wings around himself, and curling his tail up against his chest, all warm and cozy.

Asmo greatly prefers sleeping beside someone, feeling much more well rested when he's not alone. He doesn't actually get the chance to cuddle with people all that often, but he sleeps best when he does, and he'll be absolutely all over his partner because of it. Tangling their legs together, wrapping them up in all his limbs, and nestling his face into the crook of their neck is a necessity for him. He'll wear pajamas if they ask him to, but he genuinely thrives off of skin to skin contact.

Beelzebub

Beel doesn't have the greatest sleep schedule, but he's one of the most predictable sleepers in the house. He typically follows a set schedule, including a general time in the middle of the night where he wakes up feeling hungry and empties the entire fridge without realizing it before going back to bed. Other than that nightly excursion, he's a very sound sleeper, being difficult to wake and usually not moving much. He does have a habit of chewing things in his sleep a lot though, leading to many ruined pillows.

With his partner, Beel is a very sweet and cuddly demon. Not only does he love the intimacy that comes with sleeping beside someone, it also does wonders for keeping his nightmares at bay. He may be a massive guy, but he loves being the little spoon and very much enjoys being held in general. He easily takes up most of the bed on his own, but luckily he's so soft and warm that they can just sleep on him instead. He's much less likely to get up if he's sleeping with someone, mostly because he'd be crushed if he accidently interrupts their rest.

Belphegor

Despite always seeming to be tired, Belphie has the most chaotic sleep schedule of the house. He can and will fall asleep anywhere at any time, regardless of how uncomfortable he looks. He does sleep best in his room, though, both because of the privacy, and also because his bed is practically a nest of comfort. It's covered in multiple blankets, pillows, and even a few stuffed animals, all for him to burrow underneath and surround himself in warmth and softness.

Belphie regularly drags his partner into napping with him throughout the day, and properly sleeping through the night with him isn't all too different. He's incredibly fond of cuddling, often using them as his pillow and wrapping himself snuggly around them like a koala, keeping them stuck in bed with his weight. He practically radiates an aura of warmth and sleepiness, making him unbelievably comfortable to sleep with, though it does also make waking up more difficult. On rare occasions, he does sleep walk, but mostly they'll just catch him mumbling in his sleep.

[demonsandco]

um hello do you have a rules post i can see...? i want to make a request but i want to make sure to follow rules!! ♡ thank u!!

I swear one day I'll get around to making a rules post, but as long as the request doesn't involve shipping the brothers and anything with Luke stays platonic/familial, it should be fine!

I do stick to keeping MC gender neutral regardless of if the request specifies a gender, and while I'm considering writing for Mephi and Raph in the future, I don't feel like I've got a good grasp on them yet.

There's technically no character limit, either, but requesting less characters usually means I'll manage to answer it faster or with more details.

[demonsandco]

I would LOVE to know how Asmo would react to a human, while seeing his demon form for the first time, was like “:0…You look SO COOL!!!”

It's very rare to see Asmo of all demons speechless, but calling him cool seems to be all it takes.

On one hand, he's more than happy to show off to a human with good taste. He knows that his true appearance, and demons in general, might be considered scary or unpleasant, but he thinks it's a complete shame that they can't admire his beauty.

On the other hand, "cool" isn't exactly a compliment Asmo's used to, and while he's flattered, he's going to do everything in his power to earn himself a few more compliments from them, preferably ones that he sees as more fitting.

It's almost like he's putting on a show, striking poses to show off his demonic features and even offering to let them feel his smooth, arching horns and the soft leathery expanse of his wings if he's close to them. He'll keep it up, becoming increasingly dramatic with his posing, until he decides they've showered him with sufficient compliments and praise. Of course, he'd never turn down more attention if they'd prefer to keep admiring him.

He thrives off of praise and positive attention, but admiration towards his true form is extra flattering.
