A debt, recurrent.

A sequel to A debt, repaid.

BSD Ogai Mori x fem!reader

NSFW 18+ MDNI

Authors Note: I had previously skirted around the idea of writing something that directly involved Elise, just because her existence is like— one of the major icky points of this character, but I had a request to do like a nanny!reader x mori, and I was like “how can I do this in cannon universe while making it make sense while also making sure it isn’t gross.” And this is what popped out. In this story, it is implied in this that Mori does not actively use Elise in any sexual activities, even though I have no idea if that’s been confirmed or denied in the manga/show. I just prefer the thought that he hasn’t. Makes me sleep better at night. That being said, I still don’t condone any actions associated with this character/the entire Lolita-loving trope, but being able to interact with things that have caused me trauma in the past in a Safe space makes me very horny happy. and I am so uncomfortably horny for this old man.

Synopsis: Mori needs to go to a meeting, and needs someone trustworthy to watch Elise. She chose you, much to your displeasure, and you spend the evening catering to her every whim. Mori returns home to find you in a vulnerable state, and who is he to refuse such a gift?

ELISE IS NOT INVOLVED IN ANY NSFW CONTEXT, AND IS ACTIVELY TAKEN AWAY AND TUCKED INTO HER OWN BED BEFORE MORI DOES ANYTHING TO READER

You flinched at the sound of the door to the lounge swinging open, and very light footsteps accompanied by heavier, slower ones.

You were just trying to have lunch with your coworkers, and you certainly weren’t expecting to interact with the boss today, or his… ability.

”hmm…” the little girl seemed to tap her foot in thought, and you kept your head down, though if you looked up and to the side, you could see her shoes in the corner of your vision. You could see his shoes too, standing directly behind her.

“I want to play with… that one!” She said with a demanding tone that really grated your nerves. It’s not that you disliked children, you just despised spoiled brats, and Elise was notorious for being just so, which was exactly what Mori wanted from her, the sick bastard.

”Are you sure, my dear? That one has a bit of an attitude, I don’t know if she’d make the best playmate for you tonight.”

Your heart sank into your stomach. There were only two women in the lounge today, yourself and another young recruit who was well known for keeping her nose down and following orders without question.

Is it too late to throw yourself out a window? You're only on the fourth floor, it should be fine, right?

“I said I want that one!” The girl, if you can even call her that, stomped her foot with furious impatience. “Did you not tell me I could have whatever I wanted today, Rintaro?”

The boss of the port mafia sighed, the smile reading through his voice— you could hear it in his tone, though you refused to look up, still staring blankly at your sandwich as if you could disappear into it if you tried hard enough.

“Yes, that I did, my darling.”

Mori called your name, making everyone in the lounge snap their gaze to you.

If you weren’t so pissed off, you might’ve felt your cheeks heating up.

You stood, setting your sandwich to the side as you made your way to stand in front of your boss, back straight and eyes forward.

“Yes, boss.”

“Come with me, I have an assignment for you today.”

The entire walk to his office was silent, save for Elise whining about not wanting to see another tailor for another year. The girl seemed adamant about having enough dresses to last the rest of Mori’s life, and even threatened to cut that life short if he pushed her any further.

Could she even do that? Could an ability kill its user? You almost hoped she would actually try it.

When inside Mori’s office, he sat, gesturing for you to take the seat in front of his desk—which was strange, as most of the time his underlings would just stand to receive their orders.

Elise just wandered off, sitting in the corner with her pencils and paper.

“I’m going to be out for the rest of the day, well into the evening, and I need you to entertain Elise for me while I’m gone.”

You knew this was coming, but it still felt like a lead brick was sitting in your stomach.

“Why can’t you take her with you?” You hissed.

“I’m going to neutral ground for a very important meeting, where the usage of abilities will be prohibited.” Mori rested his head on his folded hands, his dark eyes flickering between yours, face unreadable.

“Then why can’t you just send her away?” You said, eyes flitting to the side as you kept your voice low, not wanting her to throw a fit because you were talking shit. “Just… release the ability, or whatever?”

Mori smiled, his head tilting to the side. He reminded you of a venomous snake. Beautiful to look at, dangerous to let close.

“It takes a lot of energy to reform her once she’s gone, you know. I have to be at peak condition in case of emergencies. Why else do you think I keep her around, give her a room on my floor of the building, and take her with me wherever I go?”

Because you’re a fucking pervert.

“Because you’re sick in the head, Rintaro!” Elise voiced your thoughts aloud, chucking a crayon across the room that smacked your boss directly in the side of his head with an audible thwack.

Huh. Maybe the kid wasn’t so bad after all.

He merely smiled, as if he was as happy as he could possibly be.

“So you see, I need someone to watch over her, someone trustworthy, and entertaining.” He said, looking at you from beneath his long lashes. “And she just so happened to choose you.”

“You think I know how to keep a kid occupied? I’m probably the least entertaining person on the fucking planet.” You hissed, white knuckling the arms of the chair.

“I don't know,” he said, voice low and teasing. “I find you very entertaining.”

You certainly felt your face warm that time, and you couldn’t necessarily blame it on anger. You were pissed, sure, but it couldn’t be that hard, could it?

“Fine.” You said, crossing your arms across your chest. “But you owe me.”

He raises a sleek brow at you, as if surprised by your words.

“I owe you?” He said, voice light and airy. Deceptive, poised. Ready to strike. “What makes you say that? Am I not your employer? Do you not take your orders from me, from those above you in rank, little one?”

“Babysitting isn’t in my fuckin’ job description, asshole.” You hissed, somehow not afraid of the consequences. “So you owe me one.”

What, do you think he’ll give you special treatment because you let him fuck you?

Surprisingly, that almost seemed to be the case, as he merely relaxed back into his chair and smiled, his tired eyes roaming your body without a care in the world, as if you weren’t paying attention.

“Very well. If I’m satisfied with Elises care, I’ll owe you one.” He said.

Suddenly, his eyes turned very dark, his smile a tad more menacing. A snake in the grass, showing its colors.

“However, if she is displeased with your performance, I’ll have to implement some kind of corrective action, yes?”

You glanced off to the side, looking at where Elise was sat, scribbling on the paper in front of her like it wronged her somehow.

“Deal.” You said.

How hard can it be?

————————————

Mori must've said something to the staff on his level, because once he left, Elise dragged you to a floor of the base that you’d only ever been to once before, and all the guards simply ignored your presence entirely.

They opened doors for you and the girl, closing them behind you, but otherwise there was no acknowledgment that you might’ve been somewhere you weren’t supposed to be. Completely unlike the last time you snuck in here, having to wait until the guards were switching shifts to sneak in unnoticed.

Elise was bratty, demanding, borderline unbearable. But you squared your shoulders and muscled through, just like you would any other job.

After dragging you around aimlessly for what felt like hours— she wanted a tea party, but you had to follow the dress code to enter, as per her rules. Which means you had to drag her all the way down to your apartment so you could bring that stupid fucking dress you’d bought upstairs, changing into it in one of the many bathrooms lining the halls.

Elise seemed satisfied though, and spent time putting little clips and bows in your hair, lining your wrists with bracelets and your neck with a couple little necklaces.

She requested sweets, and real tea, though you weren’t entirely sure if you brewed it properly, but she didn’t complain, only sipped it from her pink tea set and poured her gigantic teddy bear another cup.

“Do you really have to keep up the act even when he’s gone?” You asked, though you kept your voice small, as not to offend her.

“I am what he desires me to be.” She simply said, eyes closed, prim and proper as she sipped her tea, like a little girl pretending to be a princess.

“Were you always like this?” You asked, cringing a little.

“No.” She said, huffing. “People change, but Rintaro’s always had a few screws loose, so it only makes sense.” Hearing her speak such words in such a tiny little voice almost made you giggle.

”I suppose he’s lucky he has you, or he’d probably be in prison.” You rolled your eyes, then realized what you said, finally laughing a bit. “You know, for things besides being the boss of the port mafia.”

To your surprise, she let out a snort, sitting down her teacup as she giggled a bit.

“I’d like to see him locked up.” She said, “He wouldn’t last a day in there without me!”

That made you snort too, picturing your boss without all the luxuries of his rank was certainly amusing.

Your sick curiosity got the better of you, and you weren’t sure if she would answer, but you really wanted a reason to hate Mori, to get over the strange, twisted feelings that had been brewing in the pit of your stomach, so you tried to ask anyway.

“Has he ever…”

Her eyes thinned, and it didn’t look entirely like anger, but she certainly wasn’t giggling anymore.

“If your ability conjured the perfect knife to cut up strawberries for cake, would you turn around and try to use it to brush your hair?” She asked.

Your brow furrowed, trying to wrap your head around what she was saying.

She rolled her eyes, scoffing at your confusion. “I am a weapon. Whatever form I take is irrelevant to my use. You would want your knife to suit your own personal ideals, would you not?”

She didn’t outright answer the question, but you think you get the point. Considering your strange and mixed feelings towards your boss, it's probably best if the answer to that question remains an inferred ‘no.’

Such complex thoughts coming from such a tiny looking girl kind of made you laugh again though.

“Enough talking!” She suddenly stood up, stomping her foot. “I want to watch a movie!”

It turns out, she didn't want to watch a movie in her own room, or the living room, but instead demanded that you watch the movie with her in Mori’s room, which apparently had the “big big TV.”

The sun was setting, and you were exhausted from following her every whim all afternoon and evening, so instead of getting flustered and trying to convince her the living room was a better idea, you just gave up, stripping off that stupid dress and chunky jewelry and crawling into the bed with her in your shorts and undershirt.

You felt embarrassed crawling into his bed after what you’d done here weeks ago, but the sheets were different, and the blankets smelled fresh, so you could delude yourself into thinking it was an entirely different bed.

She picked Spirited Away, saying she liked the ‘no face guy’, and how hungry he was. She giggled and said that the parents deserved to get turned into gross pigs for being so stupid in the first place, and that might’ve disturbed you if you weren’t so tired.

The last thing you remember is the feeling of Elises head falling on your shoulder, and wondering what you did to get on her good side. She’s a nightmare. She actively terrorizes the other members of the Port mafia just for her own amusement, and she’s just falling asleep on your shoulder? Do abilities even need sleep? But sure enough, her breathing was even, and her eyes were closed.

You smiled, realizing you can’t have done too shitty of a job if she was so relaxed.

———————————

When Mori peeks his head into Elise’s room and doesn’t see her sleeping form in her frilly pink bed, he worries a little.

Not much, maybe mostly for you, in fear that she’d have you strung upside down and dangling from the roof somewhere in some midnight game to amuse her, but he’d told her to behave, so he hoped all was well.

Mori thought that perhaps he should get out of this ridiculous suit and change before he goes looking for Elise, that meeting had been far too stifling, so he at least needs to hang up his jackets and get more comfortable before he can go on any longer.

When he steps into his room, the first thing he notices is that his TV is on, its large screen illuminated with the ending credits of some cartoon, and then he looks into his bed, and his heart stops.

Elise is cuddled up right next to you, snuggled in with your arm wrapping comfortably around her little waist as you both sleep peacefully beneath his luxurious blankets.

The soft part of him wants to coo and take pictures to torment Elise with later. Another darker, more urgent part of him is eyeing you, your tiny, tiny shirt riding up your waist, your hair sprawled out on his pillows, a few stray bow clips still caught within, your arm around such a treasured piece of him— like you valued it just as much as he did.

He eyes that frilly little number you wore for him those few weeks prior, just sprawled out, lying on his floor; and surmises that Elise must have demanded some kind of dress up game, the little tease. She probably did it just to annoy you, not thinking you’d actually have something to suit her criteria.

He rounds to the side of the bed that Elise is on, carefully and slowly prying her from your hold. He very gently takes her down the halls to her own room, tucking her into bed. Any other night, he might have stayed, maybe woken her up to talk with her about her day, tease her a little about how good she must’ve been today, but he had far more pressing things to focus on, like the little one he’d left still sleeping away in his bed.

After all, if you’d done a good enough job that Elise fell asleep comfortably in your arms, then he owed you one, didn’t he?

Keeping his steps light, he made his way back to his bedroom, standing at the side of the bed to observe you once more.

Your brow was soft, face passive and serene, so unlike your waking moments where all you seemed to do was stare ahead with that tortured look on your face— like you hated everything and everyone around you.

How he craved to see you lost in yourself again, falling apart at his touch and untroubled by the burdens of your life. Having that kind of power over you sends his mind reeling, and ever since that last evening in this very room— his fingertips twitched at the mere mention of your name.

The crushing desire to claim, to take and mold you into a perfect little doll, just for him— it was overwhelming.

But he resisted.

After all, it was that fiery spark that drew him to you in the first place. If he were to break you of it completely, that would ruin the entire appeal.

Perhaps just in these private moments then, he’ll train you to let go slowly, but give you enough leash that you may still keep that delicious fight in you.

He saw the way your eyes trailed over him whenever he was in your presence, no doubt remembering the way he pulled you apart and pieced you back together over and over again that night. He knew you hadn’t been going to any of your little friends anymore, your evenings spent alone in your apartment, or so his people tell him. You still wanted him, that much was evident.

So surely you wouldn’t mind if he helped himself? You seemed to be begging for it, placing yourself so sweetly on this silver platter of silk sheets, sweet and ripe for his taking.

He removed his jackets and scarf, setting them on the desk chair before unbuttoning his dress shirt and crawling slowly into the bed behind you.

You stirred slightly, making him pause, but you simply rolled onto your back, hand twitching against his pillow.

“Heavy sleeper?” He whispered, a grin spreading like a wildfire in a dry field. “Or did my little darling just tire you out?”

He lay on his side, still observing you like a hawk, watching for any change of breath or movements that may indicate your return to consciousness.

He allowed himself to indulge a bit, dragging a fingertip up the soft skin of your stomach, raising your little shirt even further until it was tucked underneath your perfect breasts. He swirled the pad of his index finger along the center of your torso, watching the goosebumps raise as he circled around your navel softly.

He dipped lower, toying with the hemline of those itty bitty shorts you were wearing, the spandex clinging to your form deliciously.

He pushed the blankets down just a bit further, below your knees, not wanting the change in temperature to startle you awake if he removed it completely.

He watched your eyebrows twitch ever so slightly as he ran his fingertips along your covered core, just a tease of a touch, simply for his own amusement.

Then he pressed a bit harder, enjoying the little groan you let out.

“Even in your sleep, you’re still so responsive.” He whispered, licking his lips.

He brought his hand up to toy with the hemline of those shorts again, watching your stomach dip at the touch of his fingers slipping beneath.

“I wonder if you’ll let me slip these off, hmm?”

He slowly rose to kneel beside you, hooking his fingers into the sides of the spandex, shimmying them down slightly to gauge your reaction.

You were as still as stone, breaths even and eyes closed, save the occasional twitch of your fingers.

“So good for me,” he mused.

He continued sliding them down your thighs, exposing you fully as he realized— much to his satisfaction— that you wore no panties underneath.

He grinned at the slight glisten to your folds, stopping the pull of your shorts right above your knees to admire the sight for a moment.

Still, you slept, completely unaware and unbothered. He slipped your legs free from the blankets, fairly certain that he could be a little less cautious than before, and pulled your shorts off completely.

He sat your legs back down, a little more spread than before, and kneeled between them to admire you closer. He ran his hands up your delicious thighs, loving the way your skin prickled as he went.

He saw the way your nipples perked beneath your shirt, smirking to himself as he pushed the little scrap of fabric further up your chest, exposing your breasts to him completely.

“A little cold, are we darling?” He whispered, running a finger along one pert nipple.

As much as he desired to toy with your breasts a bit further, he did not know how long this glorious window of uninterrupted play would last, and wanted to enjoy himself to the fullest while he was able.

Pushing your thighs to spread completely for him, he laid down on his stomach to watch up close as he spread your folds, using his thumbs to pull you apart and gaze at the glistening treasure you kept so guarded from him.

He gingerly lapped a firm strike from bottom to top, eyes watching your face for any changes as he savored your taste.

“You taste just as delectable as I remember, little one.” He whispered against your clit, flicking it with the tip of his tongue and enjoying the sleepy little whines that poured from your throat, still lost in the throes of slumber.

He indulged himself further, licking and suckling along your core and pressing his tongue shallowly into your little hole until you were absolutely dripping for him, his cock twitching at the way you whined softly in your sleep.

He removed his gloves and tossed them aside, gingerly easing an index finger into your waiting hole, your juices easing the slide.

In your sleep, you were so soft, so pliant. Your walls gave a little clench at the intrusion, but he was very amused at how unrestrained you were. He added a second finger, marveling at how easily they slid in, your walls so accommodating, so plush.

“You know, darling,” he whispered, pulling back to kneel up and work his belt open, uncaring of the wetness along his fingers. “Like this, I don’t even think I need to work you open for me.”

Unbuttoning his pants, he finally pulled his aching cock free of its confines, having been neglected from the very beginning in favor of the mental satisfaction of such activities.

“I think you could take me just like this,” he said, stroking himself as he watched your chest rise and fall, unfettered, head resting beautifully on his pillows.

He pulled a spare pillow from the opposite side of the bed, gently pulling up your lower half to place it under your ass, hoisting you up to a proper height.

You squirmed, mumbled a bit as your eyes rolled beneath their lids, your hands twitching and thighs shifting.

He paused for a moment, almost worried you’d wake before he got to the best part, but it really didn’t matter when you woke up, you’d be taking his cock so sweetly for him either way.

After you settled back down, he thumbed over your clit once more, enjoying the way your sex clenched and glistened for him. Stroking himself a moment longer, he finally gave in and leaned forward, rubbing the head of his cock along your folds, reveling in the way your wetness coated him.

With one hand supporting himself in the bed beside your waist, and the other guiding his cock, he finally, finally pushed against your entrance, groaning at the warmth parting so deliciously for him, wrapping him in your hot and pliant embrace.

He was right, your walls graciously sucked him in, still snug, but the lack of preparation didn’t seem to matter. As he pushed further into your welcoming softness, he shifted, placing his hands beside your head to lean down and press open mouth kisses along your neck, sucking marks in plain sight, where everyone could see.

He wanted to own you. He technically did— given his rank compared to yours, but he wanted more. He wanted to consume you entirely.

He didn’t care anymore, in fact, he wanted you to wake now, to wake to the feeling of him inside you, fucking into you like you were his to do with as he pleased.

With a rough snap of his hips and a nibble beneath your ear, he finally pushed in fully, his hips slapping against yours.

You gasped, eyes finally popping open as your head rose from the pillow, a rough moan ripping from your throat as he started a rough and steady pace.

“There she is,” he groaned in your ear. “How nice of you to finally join us.”

Your walls clenched tight around him, your eyes wide as you pressed against his shoulders in a half hearted attempt to push him away.

“B-boss?!” You stuttered, your brow furrowing in confusion, in worry. “What are you— Mori!”

You moaned as he grabbed your thighs, pressing them into your chest as he threw your calves over his shoulders. The motion left your little white socked feet dangling uselessly behind his head as he brutally angled each thrust against your g-spot.

Your hands moved to grip at the loose shirt hanging by his collarbones, fingernails digging in but not hitting his pale skin. He almost wanted to shift positions to remove his shirt, maybe let you rake those blunt nails down his back so he too could wear marks of this moment.

But the way your eyes rolled back and you pushed your head to the side was too good, it was like you were trying to hide from him, hide how much you loved this.

“Where are you trying to run, little darling?” He breathed, a wicked smile ghosting along your cheek as you flinched, biting back moans that made your lips bruise.

“I… why are you—“ you couldn’t form proper words, let alone a sentence, and he shuddered at how far gone you already were, your mind still blurry from your slumber, body reacting to him so beautifully.

“You were so pretty in my bed, laid out for me like a little treat.” He bit at the sensitive flesh of your throat, groaning when you squeezed around him. “I simply am just taking a bite of what’s mine.”

You cried out at that, squirming under him as he felt your walls twitch and tremble, your slick forming a ring around the base of his cock, the filthy, slick sounds making his head spin.

“That’s what you are, isn’t it?” He said, bringing a hand to your face to force you to look up at him, your big doe eyes wide and wet with unshed tears. “That's what you desire to be? Mine?”

You bit your lip, and he could feel you tense, trying to stave off your orgasm, as if he would ever not succeed in making you cum.

“Say it,” he hissed, thumbing your bottom lip from between your teeth. “Tell me what you are, hmm?”

His hips continued to slam into you, and he could feel himself nearing his own limit, but he knew you were right there— right at the precipice.

You were so stubborn, and oh how he loved that about you. How he throbbed when you shook your head, refusing to speak even though you clung so tightly to him, even though he could feel your walls pulsing with the need to release.

“Tell me.” He nearly growled, his pace never faltering despite the burn of his own orgasm being held back. “Who do you belong to?”

You looked like you were going to deny him once more, but he saw that sparkle of need in your eyes, so he wrapped his hand around your throat, applying delicious pressure at the sides, restricting the blood flow to your pretty little head.

He was reminded of how small you were like this. How easy it would be to snap your little neck if you were an adversary. Instead he was delighted when your eyes rolled back once more as he growled down at you.

“Who do you belong to?”

He released his hold, and you gasped as your walls fluttered, your release crashing into you like a train, moaning and babbling up at him in your pleasure.

“Mori! I’m yours! I’m yours— I wanna be yours, I wanna belong to you—!”

He groaned, letting himself go as you continued your babbling, feeling his cock twitch against your still fluttering walls, the pressure of you squeezing him so tightly was almost unbearable.

“That’s it,” he moaned. “Mine, all mine.”

He felt himself tip over the edge and leaned down to bite at your throat again.

“Now take what I give you, take it all.”

You cried out as he spilled into you, his hips finally stuttering with each pulse of his hot cum into your cunt. You gripped him tightly, keening as he panted in your ear.

When he was finally done, you fell back, arms spread wide as you stared lazily up at the ceiling.

“Did you enjoy your evening?” He grinned, pulling his softening cock from your leaking core, enjoying the way a little dollop of his cum oozed at your entrance.

“You’re a fucking asshole.” You groaned, throwing an arm over your face.

He tucked himself back into his pants as he chuckled.

“After all that you still have the energy to be so acrimonious?” He teased, getting up to retrieve a cloth from the en suite.

“You’d be pissed off too if someone woke you up by shoving their cock in you!” You shouted from your place on the bed, clearly spoiled rotten from the last time he fucked you, knowing full well that he intends to clean you up before letting you sleep.

He rolled his eyes to the side as he made his way back to you, waving his hand dismissively to tease you. “I wouldn’t be pissed, per se. Perhaps a bit startled, maybe murderous, maybe indulgent. Depends on how nice the cock is.”

He grinned as he watched you get flustered, tugging your shirt down and crossing your arms over your chest.

“Salacious, depraved, idiot old man.” You grumbled, and he laughed.

“Are you saying you didn’t enjoy yourself, little one?” he leaned down to wipe the sweat and juices between your thighs, and watched with keen eyes as you relaxed, letting his cum pool out of you and onto the waiting cloth.

His spent cock twitched in interest, and he flashed his eyes back to your face, gauging your reactions.

You were red, still indignantly looking at the ceiling as he cleaned you up.

“I’m not saying that, don’t put words in my mouth.” You said, pouting like a spoiled rotten child.

Oh, how he enjoyed you. He was going to soak in every second of your time. He wouldn’t let you run away again and pretend like this wasn’t happening, like you didn’t want him. No, you were stuck this time.

His cock swelled again, watching you grumble and pout.

“You’re right, darling.” He said, pulling away to undo his pants once more, reveling in the way you chewed on your swollen lips, your thighs clenching together. “I have better things I can put in your mouth.”
