➤ author's note: it’s finally out of my drafts, oh my god. finally, a proper fic after thirsting so much for someone who hasn’t even debuted yet

the iluna institute of mythics tends to be hesitant when it comes to enrolling succubi and incubi into their ranks despite the strict policy not to discriminate based on species, that’s what the entire point of the campus was about! it’s not because they have anything against beings from hell, but they know that from the very moment the demon steps onto the site, everyone won’t be able to keep their eyes off them and chatting among themselves about how hot the new student is. it puts the entire school on pause because of how people skip their classes just to get a glimpse of them and are far too lovesick thinking about their next interaction rather than their assignments. don’t even get them started on the nightmare that is their birthday or valentine’s day, presents in front of their locker fill up the halls and leave no room to pass through them.

the worst part is that they are fully aware of all the attention they get and make no effort to put a stop to all of the nonsense— most actually try to milk it for the massive confidence boost added to their already inflated ego and the gifts they receive daily to have their hearts won. it’s just what they always do, feeding off the affections of others for their own powers. the hype doesn’t die down until every student is rejected or until they decide to get a lover and snap others out of their delusions of dating them. it took a lot longer than the administration would like, but after a few months, you found yourself a lover and the school is finally slowing down to its regular schedule.

━━━ .°˖✧ scarle yonaguni ˚₊ ⊹

╰₊✧ the beautiful and alluring enchantress of iluna, truly, there isn’t anyone who could be better back for you as two lovers with such a seductive aura to them… at least that’s how it seems to outsiders whowould look at your relationship thinking that you both were dommy mommies who fight each other to the death for the right to top, but anyone who has spoken to scarle would know who’s really in charge in the relationship. scarle still can’t believe that she pulled you after engaging in conversation with you and revealing her true shy and awkward self without the help of a love potion (which she totally wasn’t intending on actually brewing, that would be crazy aha). she still trips over herself which talking to you, and even though you find it to be so charming, she dies a little inside every time you lovingly bully her.

even though she’s been prepped thoroughly by your fingers, she still feels intimidated by the size of your strap that had her stomach twisting in knots. yes, it was one that she picked out, no, she will not be backing down. she gripped onto the bedsheets under her as you eased yourself into her, whining at the big stretch that burned yet felt so pleasurable at the same time. it took a minute for her to adjust, but she was quick to roll her hips back into your touch to tell you that she was ready to move. scarle’s braced herself to wait for the brute force that came with your usual animalistic pace, yet it never came because you were fixated on something else.

her eyes trailed down and widened at the sight of the shape formed in her abdomen from you bullying inches of your cock into her, skin slightly raised with your strap to show you how good she was at taking whatever you gave her. she didn’t have much time to admire it though, slamming your hips into hers and hitting her g-spot with the tip so hard she saw stars. you were to hypnotized by her that your thrusts were almost sloppy, watching intently at her fat tits bouncing and tummy bulging in accordance with your movements mixed with the loud pornographic sound of sex. the way she moans and clenches around your cock would be enough to drive anyone crazy with lust, you can’t help but wonder if your pretty and alluring enchantress was actually a succubus in disguise.

━━━ .°˖✧ kyo kaneko ˚₊ ⊹

╰₊✧ ah yes, the one you pursued because he was the only one who didn’t fall at your feet upon meeting your eyes for the first time. you always get what you want without any effort, so it was both dejecting and exciting to see someone who scoffed and rolled his eyes at your flirtatious behavior that would have had anyone else fainting on the spot instead. kyo was simply someone you thought you couldn’t have, making you want him even more. it did embarrass you to get off your high horse and flirt with him like a normal person, but after noticing that he was reacting with stutters and blushes while making weak insults, you knew that you already had him in the palm of your hand and made the humbling move of being the first to ask him out when it was always the other way around. that’s when you learned that even though he’ll always complain and be a brat about it, he actually indulges happily in everything you ask.

“don’t fucking look at me like that when you’re already kneeling between my thighs,” you giggled, looking at the blue-haired male sighed in annoyance before grabbing onto your thighs to pull you closer to him. despite acting like he was hella irritated, it didn’t translate into his actions with the way he keenly flicked his tongue against your clit and licking lope stripes along your slit. it almost made you laugh how the blunt and pessimistic kyo kaneko was secretly such an enthusiastic pussy eater. that’s what being a succubus’s lover gets you, you suppose, it really brings out another side of people in the bedroom.

while he does like to fight you for some semblance of control when you're in such a compromising position and attempt to leave you pathetic under him, you have to remind him who is really in change. it doesn’t take more than a tug on his cyan hair to pull him off of you to make him slip up with a whimper, making you snicker in response. he’s so cute when he pouts with your slick shining his lips and running down his chin as he starts complains like a brat before shaking his head out of your grip and moving on to continue with the reminder that he isn’t domming you today.

━━━ .°˖✧ aia amare ˚₊ ⊹

╰₊✧ a heavenly maiden dating a demon of lust? how scandalous! despite the forbidden romance, she’s absolutely head over heels for you as you are for her. others at the school are supportive of your relationship and your folks could care less about how you feel towards an angel, but her family is a different story. aia was already in trouble for getting kicked out of the heavens for the accumulation of her petty crimes and needed to attend the institute of mythics as punishment, so something like dating you was certain to land her in even hotter water.

╰₊✧ they were definitely suspicious of your intentions with their daughter, worried that you were just trying to seduce her and siphon power from her, but you seem earnest enough when it came to caring for their angel so they aren’t as doubtful anymore as they were when they first met you. you’ve even reached the stage where you two are allowed to sleep in the same bedroom together with the door open, but that doesn’t stop either of you from getting frisky late at night while everyone’s asleep!

“just gotta keep quiet— sounds good, angel?” you whispered in her ear as heat spread throughout her entire body with your hand reaching under her nightgown and dipping into her underwear. it sounded easy enough, but the house was as silent as a catacomb and any noise made was sure to be amplified, the smallest moan having the potential to alert someone that the two of you were up to something heaven wouldn’t approve of. aia loves to take on challenges of all sorts, however she only realized how difficult it would be when you began to toy with her clit and press your fingers past her folds into her weeping cunt that barely needed any prep with how much she wanted you. she whined and it made you chuckle softly with your wings fluttering slightly, “not as easy as you thought, huh?”

feeling generous enough to help her out, you raised your other hand to rest over her mouth to remind her to remain silent and to muffle any sounds that threatened to slip. she must have been into it because you could feel her tighten around you after you stretched her out with a slowly added third finger, arching her back and bucking her hips into your touch. she gasped into your hand when you curled your knuckle to feel around her gummy walls and pressing into her g-spot, something that usually had her squealing when the gesture makes her orgasm all over your hand, but all she could do was let a groan that was smothered out by your hand.

━━━ .°˖✧ maria marionette ˚₊ ⊹

╰₊✧ oh, maria looks at you with the widest, brightest eyes of puppy love— you’re simply so sexy and sophisticated in contrast of her adorable appearance and chuuni personality! she just has an attraction to girls who have more of a mature appeal, she can’t help it! meanwhile, you find her to be so endearing, how could she be one of the cutest dolls you’ve ever seen? she never felt things that her peers felt like sexual want before and didn’t have too much understanding about the action other than the biological function, but now that she’s a real girl instead of a doll, she can’t think of anyone better than a succubus girlfriend to guide her through this journey!

the vibrating toy you were pressing onto her clit was creating a strange foreign sensation within her by making volts of pleasure ripple throughout her entire body, making her core burn with pleasure as the tips of her fingers and toes tingled with numbness. it maintained an unchanging pace and the only difference in intensity came from the pressure you were putting on it, but just the slightest shift in force was enough to drive her crazy. she couldn’t tear her eyes away from the sight and neither could you, her pussy being abused by this silicone toy and reducing the cheerful mari to a pathetic moaning mess.

isn’t she just the cutest with her mouth making a perfect ‘o’ shape for her dulcet cries and her face flushed a pretty pink to match her color scheme? god, you just want her ruin her innocent mind and are looking forward to corrupting her, getting her drunk on the feeling of pure ecstasy you provide so that she’ll learn to be you for more of it— it’s just the instinct of a succubus to teach people all about their world of carnal desire! although, you think she might be even more excited than you are about discovering this new side of her that came with becoming a human and using it to spice up your relationship…

━━━ .°˖✧ aster arcadia ˚₊ ⊹

╰₊✧ it makes so much sense that he’s the celestial one because he’s so beautiful that you assumed he was a demi-god of sorts, the most enticing eyes and unique hair you’ve ever seen immediately attracting you to him (you’re almost envious of how stunning he is). similar to the doll who’s now a real human, aster perfectly balances out your foxy charms with his “cyuteness” and he’s just the right amount of unseiso to bounce off your jokes. you just love it when he makes a dirty joke before acting like he doesn’t know what you’re talking about when you catch it, always with a sly smile on his innocent-looking face and humming with his sweet-sounding voice. of course, he can never outdo you since he’s still the bottom bitch we all know and love, but it’s simply so much fun to see him try!

he’s too feeble and still too horny to deny you, so he says nothing but a weak whimper and watches you continue to fondle with his balls and lick at his sensitive red tip after you already made him cum. his heterochromic eyes were already threatening to tear up from overstimulation as they stared deeply into your mischievous ones, feeling his thighs quake and back arch at the overwhelming pleasure. your head steadily bobbed up and down, holding him down slightly so that he wouldn’t be able to buck his hip into your mouth and everything remained at your pace. from his silly ahoge to his smooth ivory skin to his needy cock was gorgeous, almost distracting you from the task at hand because you just wanted to look at him forever. however, you were certain that you wouldn’t miss the look on his face and the moan he’ll let out in a minute or two, so you can afford to look away for a moment and focus on giving him another mind-blowing orgasm.

━━━ .°˖✧ ren zotto ˚₊ ⊹

╰₊✧ one of his favorite things about attending the iluna institute is meeting other species as it’s always nice to meet another being who looked human for the most part but had things like wings or horns to set them apart from others. ren’s native planet didn’t have any creatures who feed off of live forces through seduction, so he was immediately enthralled by you and wanted to learn more about your kind. he was more interested in what you could do with your powers rather than what you could do for him and you were wondering if the life force of an alien was more powerful than that of a human, a relationship that sprouted from the roots of curiosity!

╰₊✧ ren’s actually thrilled to have a succubus partner to learn so much from, but he’s mainly grateful because he has had a bit of a problem ever since he entered young adulthood and was usually far too embarrassed to ever bring it up for previous partners. just alien anatomy things that weren’t human and biology that couldn’t be controlled, you know? he has no words to explain the wave of relief he felt when he awkwardly told you about it and you welcomed it with open arms, promising to care for him no matter how long his heat lasts or how wild things may get when he’s influenced by it. however, he can’t help but feel a bit uneasy by the almost sadistic look in your eyes.

his neediness and desperation for you increases tenfold when he’s in heat, his face buried in your tits and his cock pulsating inside of you frantic for release. he felt like he could burst with just the slightest shift of you body, but it was never enough stimulation. must you always be so vexing with rewarding promises if he does as you say? he felt like he was going to go crazy with not-so-subtle ruts into you to try and chase his high, but it was all for naught and only edged him even more. it just made you look at him with pity and coo at how pathetic he was, the alien prince infamous for destroying entire planets crying like a little bitch because you wouldn’t let him cum just yet.

he was in heat! couldn’t you be a bit nicer to him? he swears that he’ll let you torture him all you want a different time, but right now he’ll do anything for you to stop teasing him! you hummed in amusement and cupped his face to give him a kiss, running your hand over his skin and observing all of the little alien features that were normally hidden from plain set. eyes set on the glorious jet-black pointed horns atop his head, you experimentally wrapped your fingers around it feel the strange texture more properly and noticed a spark in his green eyes as electricity shot up his spine.

“oh, you’re sensitive there, aren’t you?” you cooed, pouting when you realized that he never told you about this wonderful snippet of information but smiling again when he got all flustered. you started gently, tracing patterns and running along the shape, noticing that his tail began to flick around and his cock twitching in reaction. with your motions steadily getting faster and rougher, he began letting out slurred moans and biting at his bottom lip to suppress them as he pulled you closer to his body. it barely took anything more than a light tug to get him to spill over, unexpectedly emptying himself into you and making you chuckle in response while he was huffing for air. you really needed to tease his horns more often!

request was [ iluna with a reader who is a succubus? i think it would be a really interesting concept! ]
