──────────────────── ⋆⋅☆⋅⋆ ─────────────────
Lucifer:
❤︎ As if Lucifer wasn't intimidating enough in his human form. but he looks significantly bigger, his feathered wings only emphasizing his imposing figure. When he's got you on your back and he's on top of you, his wings wrap around you two like a protective shell.
❤︎ His gloved hands grip you tighter, his nails almost peeking out to scratch at your skin. It's practically a given that him and the rest of his brothers are incredibly prone to marking you up, but the urge is a hundred times stronger when in their demon form. Which does mean they have to be more cautious with the way they mark you.
❤︎ One thing Lucifer loves to do in his demon form is have you in a full nelson while facing a mirror. It's a great display of your blissed out face that he's obsessed with, his arms holding you up, and his large wings outstretched.
❤︎ On that note, his wings are sensitive but he hates how easily he folds when you touch them. If you run a finger across his spine, he shivers and gasps deliciously. Lucifer may not be prone to subbing in his demon form, but he tries to be gentle and let you take over if you really wanted to.
❤︎ He'd groan so sensually if you gripped his horns as you rode him. It makes his whole body tense and his wings flutter weakly. They aren't the best to grab onto to use as handlebars compared to the others, but it's such a good way to get him to give you control. Lucifer's not the type to act bratty about it, but he does sulk when he realizes you've got him wrapped around your finger despite being in this powerful form.
Mammon:
❤︎ Mammon's got you sitting on his lap as you trace the markings on his chest and abdomen. He gets so cocky as he thrusts up to hit a specific spot that has you gripping his body for support. He melts at all the praise you shower him with, but hides it with a pleased smirk. "Heh, 'course yer saying that about THE Great Mammon!"
❤︎ It shouldn't be much of a surprise but he's a lot greedier in this state. Mammon's going down on you until your eyes are brimming at the edges with tears from overstimulation. And even then, it still feels like he isn't satiated. What would be incredibly hot to him is if you gripped his hair or his horns at the base and tugged. It makes Mammon straight up whimper into your body, which in turn makes you shiver in pleasure.
❤︎ Unlike Lucifer, he's more willing to sub for you. His wings aren't that sensitive, but he doesn't want you roughly handling them as it hurts more than it turns him on. Mammon's usually such a good boy, but he might end up getting a little impatient and climbing on top of you. That's when you can give him a command to stay still where he obeys, sitting there until you give him orders on what to do again.
❤︎ Mammon looks so cute under you with hopeful eyes, begging desperately to let him cum, but you always pull your hand back or use the pact to prevent him from cumming at the last second. This makes his wings twitch in irritation, but he knows better to refuse an order or else he won't get to cum at all that night.
❤︎ One of his favourite positions is where he's behind you, he's obsessed with gripping your hair while pounding you against the hood of his car or on his mattress. Either choice will let him mark you from behind, letting everybody know who you really belong to. With how greedy he gets with his bites and kisses, your whole back and lower body will be aching the next day. Mammon only responds with a sheepish, yet prideful giggle and a half-assed apology. "Heh, sorry not sorry, MC."
Leviathan:
❤︎ He's especially kinky in this form, mostly because he gets his ideas from the kind of... anime he watches. But with how knowledgeable he is, Levi knows how to provide a comfortable experience for you and makes sure the both of you know the risks. With his two dicks, it does mean twice the pleasure for the two of you as well. Also, his horns wouldn't make the best handlebars as they're pointier and there isn't much of a base you can grab. They do look very cool, though.
❤︎ He's probably the only one out of the seven of them that you can have COMFORTABLE tail sex with. It acts as a tentacle that he can control surprisingly well, thrusting up into you and even curling to hit those sweet spots. The feel of it is comfortable to grind against as well, sometimes Leviathan will have you hump his tail while he's busy with something, usually a game that he can't just quit right away.
❤︎ Cockwarm him while watching anime together. You can rest your head on his chest while you watch, and his heart is hammering under your ear. You can also tell when he's losing control and wanting to thrust into you by the way his tail lashes behind him and his breathing sounds less like himself, almost raspier.
❤︎ Levi fantasizes about breeding you, and if his anatomy is like an aquatic mythical creature, that would mean oviposition. Of course, he'd never do it without your consent. He does just feel the need so badly, especially with his sin of envy being elevated like crazy. If you let him release in your mouth, he has to hold himself back from going too rough or cumming too fast, as cumming inside you in any way makes him get so possessive. The smell of one of his brothers on you gets him angry as well.
❤︎ He would LOVE it if you used the pact on him while he's subbing. Poor Levi struggles with releasing too fast or he's just really unsure if he's making you feel good. With a few simple words invoking the pact, you could make him cum nonstop or not at all, which has him screaming your name, his tail thrashing before wrapping around your waist or wrist.
Satan:
❤︎ Satan can get unintentionally rougher during sex, but makes up for it with phenomenal aftercare. He has to be more careful with his barbed tail as he can't have it thrashing around or wrapping around your body. It can cause a lot of damage and he prefers not to have you bleeding out with just a little flick of his tail. So even in the bedroom, Satan has to keep his tail wrapped around his leg or curled up carefully in the air. If he's in a good mood, it's in the form of a question mark or swaying slowly in contentment.
❤︎ He's probably one of the only brothers most prone to entering their demon form during the act, just because he gets so emotional and passionate. So if he's angry, it's more likely you two are doing it in his demon form. Satan gets handsy and ends up leaving rough bite marks that somehow don't break the skin. He's also into a bit of impact play and sensory deprivation a bit more in this state, which includes things like spanking and shibari.
❤︎ Satan's horns can make good handlebars, especially if you use an underhand grip. It gets him acting incredibly feral. His groans almost sound like a scream as he tries to muffle his noises in your neck. His nails dig into your shoulders or waist, leaving crescent marks into your skin. It feels so good in the moment, but you both know it's going to be pretty sore in the morning or when you're taking a bath to recover.
❤︎ With how often he might be angry in his demon form, Satan might get bratty if he's subbing. Like he's pushing his backside into your hips or trying to get you to fuck him by whining constantly. If only you could grab his tail and give it a good tug to make him yelp. If you do manage to find a good, safe way to grasp his tail, pull on it a little to make him whimper, making him second guess trying to act bratty again for a while.
❤︎ Satan may like pretending to be disobedient, but he'd look up at you like a kitten who got scolded if you actually got mad at him. He'd give you full control over him and let you grab him anywhere you wanted as he fucked you or as you fucked him. He may pout at you for edging him, but his tail whips back and forth excitedly each time you pull away from him before he can cum.
Asmodeus:
❤︎ Doing it with Asmodeus would be like being affected by an aphrodisiac 24/7. Almost like his seductive power has increased tenfold just by being in his presence. You can't get enough of Asmo and it makes him very excited at how easily you lose your composure. Asmo states it as a matter-of-factly, like you were meant to be obsessed with him like this. There isn't much of a difference in his behaviour in his demon form, but it's more of how it ends up affecting you.
❤︎ There isn't a position or toy that he wouldn't use, and with how much stamina the Avatar of Lust has, he's only stopping once you get too tired. Most times, he has you up against a mirror you or on top of him so he can shower you with endless praise as his hands run along your body. He usually pinches your nipples with delicacy, letting out a sweet giggle as you arch against his body.
❤︎ Asmo's horns make for the best handlebars as they're easy to grip without your wrists or hands being sore afterwards. He encourages you to grab them as hard as you can too, whether you're riding him or fucking him from behind roughly. He lets out high-pitched moans and mewls, urging you on further. If you give his wings a nice and firm massage, it gets him so close to cumming that you can end up doing that to get him to finish instead. He's got unlimited stamina, so you could probably do that until he gets bored, seeing if he can do the same to you.
❤︎ Asmodeus would love it if you used the pact in the bedroom with him as it gives him a chance to show you how good he can beg. He looks so damn pretty too, tears running down his face, letting out angelic sobs, pathetically attempting to grab you, begging repeatedly in his sweet voice... But he'd probably be disappointed if you gave him what he wanted immediately. Almost like he's testing how much you can resist his pleas for more.
❤︎ There's nothing too different about his appearance, but you swear there's something different about his tongue and fingers. When Asmo goes down on you, you cannot get enough. His mouth is like desire itself, his tongue managing to reach depths that shouldn't be possible with any ordinary person. But this is the Avatar of Lust we're talking about, and it's his life mission to get you obsessed with him just as much as he is with you.
Beelzebub:
❤︎ Beel has to be even more careful in his demon form since he has to hold back his gluttonous instinct on a much higher level. But it does also work in your favour. He gets lost in the taste of you so fast, it makes you see stars just a couple minutes in. His grip is also much tighter on you, just enough to leave visible bruises. Beel gets too excited, he doesn't even realize... Sometimes you'll end up walking funny just from how much he was biting at your thighs or your legs in general.
❤︎ His wings don't move much and aren't as sensitive, so touching them wouldn't do as much as you'd hope. But it's also not unpleasant for Beel when you touch them, so you can include it in a back massage, which could lead to his arousal if you play your cards right. He's a bit more sensitive where the base of his wings meet his skin, so rack your nails along there and it's sure to get his breathing heavy.
❤︎ Food is the last thing on his mind, instead treating you like his last meal. He would go down on you like he's starved, and no matter how much you weigh, he's gonna have you sitting on his face. It doesn't matter if it crushes him, as if he'd mind going out that way. Beelzebub's a messy eater as well, not even bothering to wipe his face covered in your juices and his saliva.
❤︎ His horns would make decent handlebars as well as long as you reach for the middle part, closer to the tips than the base. They also don't appear to be thick, so your fingers may be outstretched more than what should be comfortable. Beel would prefer if you roughed him up in other ways, like attempting to manhandle him. He'd feel bad seeing you try to take control for him, so subbing comes by pretty easy.
❤︎ If you go down on him, it takes a lot of willpower for him to not grip your shoulders or head too tight, no matter how good it feels. Dig your nails into his thighs, suck on him hard, do anything rough with him and it gets him riled up like crazy. Combine this with Belphie at your hips and teasing you from behind and it'll be total bliss.
Belphegor:
❤︎ As if his yandere tendencies weren't prominent enough in the bedroom... He's actually more prone to angry sex than Satan. Belphie's more possessive in this form, his tail lashing out erratically as he pounds into you, your face buried in his pillows. He doesn't like the idea of smelling anybody else on you other than him or Beel, so the times you end up doing it in this form is usually out of jealousy.
❤︎ His tail isn't comfortable to hold or have wrapped around you, so Belphegor has to settle with having it curled up or swaying above him so it can't hit you. But he would tease you with it ever so slightly, like brushing the tip of his tail against your skin or even gently swatting at you with it. If it weren't for the thorny parts, you could've gripped it and tugged on him to make him whine so pathetically.
❤︎ Belphie's much more awake in this form, so the positions he'd be in would be on top of you. If he's on the bottom, it's only because he'd have more control over how you move on his cock from above. Positions like missionary would be his go-to's as he can watch your every reaction and see your eyes roll back, hear his name leave your lips that're struggling to form words.
❤︎ His horns wouldn't be the best handlebars as they're so curly. But you should firmly grasp him at the base and tug hard, it gets him near tears almost instantly. In fact, if he's being extra annoying and bratty, feel free to use the pact on him. You can order him to keep his hands behind his back so you could pleasure him but he can't touch you in return. He grimaces and bares his fangs at you, but his cute little whimpers and the way his hips buck to meet your hands let you know his gaze holds no malice.
❤︎ Belphegor lets up on the possessiveness a bit more if Beelzebub is also involved, satisfied with watching you writhe as they both pleasure you at the same time. He likes being behind you most of the time, spanking you lightly as you take Beel's cock down your throat. Sometimes he's got a firm grip of your waist as you take in Beel, whispering praise in a mocking manner. "Does this feel good, hm? Having both of us fuck you, you dirty little human?"
