Break the Rules

Summary:

Sukuna has two primary rules when he goes out; text him if you’re leaving the house, and if you’re not - don’t fucking touch yourself. It’s too bad you’ve never been a big rule follower.

Work Text:

I mean really, what did he know anyway? They were your toys, so you were going to play with them whenever and however you pleased. Even if it meant directly disobeying a very clear and very concise order.

Plus, If you were being honest, the knowledge that you were actively breaking a rule (or several) just made the blood thrumming through your veins pulse hotter, made the slide of the toys feel that much sweeter.

With that snide little pulse of satisfaction beating in your chest, you’d plucked a plethora of toys from your bedside drawer, plopped down onto your freshly washed sheets and pressed the fat head of your favorite vibrator right onto your clit. No teasing, no build up - just raw, greedy pleasure as you flicked the power up and up and up until you were squirming against it.

“Fuck that’s good…” You sighed contentedly, letting your head loll back into the plush pillows, breathing in the soft perfume of laundry detergent and remnants of crisp cologne. You’re sure you painted a sinful picture - splayed open on the king sized bed, thighs spread wide, panties still looped lazily around an ankle, hips rolling in an unhurried grind against the buzzing vibe.

Sukuna never allowed such frivolity. There was never pleasure without work, without earning it first. You supposed it’s what you’d signed up for - the rules, the structure. It was grounding, satisfying. But sometimes you just needed an hour or two of pure unadulterated gluttony.

Just as you were reveling in it - the rush of pleasure from the humming vibrations, the shiver of excitement prickling over your skin, coursing hot through your veins - your ears pricked up. It was subtle, but through the haze you swore you heard a noise just outside the room. The subtle squeak of a floorboard, then a quiet cough, like someone clearing their throat.

Your eyes flew open, and the adrenaline thrumming through your veins turned to ice when your gaze caught on the figure standing in the doorway.

Sukuna raised a lone eyebrow at you from where he was leaning against the door frame, expression one of inscrutable disappointment. Suddenly the atmosphere shifted, sharp and sizzling like a live wire in the space between you. His hulking form devoured the space, thick arms crossed as he took in the sight of you splayed open on the mattress doing precisely what he’d told you not to not thirty minutes prior. You swallowed hard, watching a muscle twitch in his taut forearm.

“Enjoying yourself?” Came his slow drawl, interrupting the silence like the sneaking slice of a blade, and even from the doorway you could hear the cold irritation edging his otherwise flat tone.

You froze, eyes wide, looking all the more like a deer caught in headlights as you slipped your hand out from between your thighs, vibrator flicked off and abandoned in the next watery flutter of your lashes.

“I’m sorry,” came your desperate apology before you could think, a vein attempt to placate the man standing before you.

Your confidence dwindled more and more as the seconds of silence ticked on. You could feel the steady pulse of anger emanating from him, turning the stagnant air between you thick and choking with unspoken reprimand. A cold unease settled over you as you watched one of his thick fingers finally move - beginning to tap against his arms, still crossed tightly over his plump chest.

“Nah, you’re not sorry,” he said finally, and took a few slow steps into the room, carmine eyes narrowed to assess the state of you. You were frozen - still spread open over the mattress, though your knees were tilted inward in an instinctive shield. A plethora of toys he’d bought over the years surrounded you, scattered and guilty like bloody fingerprints at a crime scene. “You’re gonna be though.”

It was times like this when Sukuna truly scared you. His outward irritation you could handle - all aggravated grumbling and wild obvious fury like the blaze of a forest fire, never directed at you specifically. But when his anger was pinpointed like this, simmering and sharpened to a needled blade, like the cool burn of ice - you found yourself unable to do anything but tremble in its wake. Your own confidence whittled down to nothing beneath his quiet disappointment.

“I really am sorry sir,” you tried again, voice barely an audible squeak.

“Oh, being polite isn't gonna save you now, pet.”

You watched his thick jack twitch, teeth clenched tightly behind a barely concealed snarl.

“Which one was it, huh?” He interrogated, flaming eyes roaming over the different toys before they finally landed on the one you’d tossed aside - a big wand vibrator - your favorite. “This one?”

With a few purposeful steps he was beside the bed, and he leaned down to wrap his fingers around the base of the toy, holding it up to you. Your eyes flicked up to it, tracing the smooth curve of the head where your slick was still turning the silicone slippery - blatant evidence of your disobedience. Your lips parted around a shaky breath, and in the same motion your tongue darted out to wet them without thinking.

Sukuna puffed a hot breath through his nostrils, nodding to himself in confirmation. “Yeah, this one.”

His spare hand dropped to your knee, fingers tapping at the outside firmly.

“Spread.” He spoke in a tone so low, so final that you could do nothing but acquiesce. Your legs split almost entirely of their own volition, and with a controlled hand he tucked the thick vibrator snugly between them.

“Since you like this one so much, you can have it.”

You jolted when the firm head of the vibe hit you once more, cooled slick silicone kissing your sensitive clit - still hard and needy from your previous play.

All of it.”

He flicked the toy on, and a blaze of pleasure hit you like a freight train.

Oh…” You gasped, legs falling open limply either side of his thick forearm.

It started pleasant enough, gentle rumbles massaging your sensitive pussy in slow delicate rubs. But within a few seconds Sukuna’s wayward thumb had clicked the toy up to its previous setting, holding the toy firmly as sweet little rumbles turned to a furious buzzing. You couldn’t help your spineless cry when he didn’t stop there, flicking higher and higher until you found yourself scooting back into the pillar of the headboard in a vein attempt to escape the sensation.

Despite the toy being your favorite, you were certainly no power queen. The highest you’d dared to go was still a significant way from the maximum, and even then you usually preferred working yourself up the edge with a slow teasing rumble. Sukuna had no such considerations, and whatever patience or sympathy he might have had for you had shattered when he’d walked in to find you breaking one of only two rules he set for you, and he was always one for re-enforcing his rules.

Each time he pressed the vibe back to you, your legs clenched inward around his broad forearm, an instinctive action you couldn’t stop. You could sense his rising annoyance, building higher each time you wrapped defensively around him and he was forced to shove your legs back open repeatedly. This continued until finally you heard a sharp puffed exhale through his nose, and he tossed the vibe aside, turning and storming from the room without a word.

For a heart-stopping moment you simply lay in utter silence atop the sheets, frozen. Thinking he might genuinely be too angry to handle you, but a few moments later he stalked back through the doorway holding a shining silver bar in his hands. You shook your head in disbelief as you watched him approach, listening to the fleshy slap as he tapped one end of the bar against his open palm as if it were a baton.

“No…” You pleaded, eyeing the spreader bar glinting in the light like it was the muzzle of a rifle.

“Oh yes, princess,” Sukuna mocked when he reached you, big hand looping tight around your ankles so he could tug your trembling legs apart once again. “Spread ‘em. Now.”

It wasn’t a request, it was a command - firm and final, and you could think of nothing else to do but to comply. With a frown you lifted either trembling foot through the leather cuffs at end of the thick metal bar, guided by his firm grip around either ankle. He hummed, cinching the straps tight until you felt the pressure of the leather biting your skin.

Sukuna stepped back an inch, admiring his handiwork as you lay back against the pillows. Legs spread wide, squirming against the restraints - giving him an unrestricted view between your sticky thighs. You wanted nothing more than to close your legs, scurry back and hide from him, shame already licking hot up your neck.

“There we go, much better,” he purred, “y’know I don’t like doing this, but you just can’t seem to do what you’re told.”

That was a boldfaced lie and he knew it, you could tell just from the way his eyes were glittering, pupils blown dark and desirous, that he was loving every moment of this, of punishing you.

“So when I tell you to keep your legs spread, you better keep them fucking spread. ‘Kay?”

With that biting demand, he tucked the toy once again between your now spread thighs, and you jolted in place when the vibrations hit you once again. He hadn’t bothered to start low, instead he’d hiked the setting to near maximum, leaving you slack-jawed and panting, writhing against the spreader bar. Pleasure or pain, you realized in the moment that your body couldn’t tell the difference anymore, all it knew was that whatever it was - it was too much.

“G’nna cum…” You managed to gasp, blinking up at him with half-lidded, lust blown eyes.

He met your syrupy gaze with a stern coolness that did nothing to ease the heat swirling in your belly, and simply tutted in reply to your feeble whining.

“Did you really forget all of your manners in the single hour I was away?” He questioned harshly, and you watched the sharp line of his jaw fade as your eyes rolled backward.

You shook your head frantically, eyes squeezed closed as you felt your thighs begin to shake, nerves shot through with the intensity of the vibration.

“Oh please,” you huffed, “hngg… can I please cum, sir? Please?…”

“Good girl,” he purred, “go on then, cum for me.”

Oh thankyou… thankyouthankyouthankyou…”

Your orgasm hit you hard, a stunning wave of heat and pleasure that left your head spinning behind your eyelids, stars dancing in the blackness there. Your whole body trembled, caught halfway between grinding up against the vibrator and pushing down into the sheets away from the onslaught.

The sounds you made were guttural - choked moans and grunts as you clenched helplessly around absolutely nothing, sure that you were soaking the sheets below. When you finally came back down you felt exhausted, body still shaking with residual throbs of pleasure.

“Okay ‘kuna, ‘s enough.” You panted, blinking up at him.

But the vibrations didn’t wane, and when your vision refocused you found that he was watching you with that lazy self-gratified smirk of his. It was then that you realized just what kind of game this really was.

You shook your head frantically, mouth tugged into a frown, lower lip beginning to wobble as the incessant buzzing continued.

“It’s too much, please no more,” you begged, fingers tightened to clenched fists atop the sheets, scrunching the fabric into a wrinkled mess.

You squirmed, trying desperately to pull away from the toy, but to your dismay a large palm slid over your belly, angled downward to pin you against the mattress.

“Oh well that’s just too bad,” He mused, fingers teasing down to slide either side of the vibrator, spreading you open until there was nothing between your sensitive nub and the slick silicon, no fleshy barrier to dull the sensation.

“Bad girls don’t get to make requests, and make no mistake - you’ve been a bad. fucking. girl.”

His voice came out an accusatory hiss, and his thumb flicked the vibration up higher and higher with each word, flourishing the sharp sounds with a plasticky click as he increased the intensity until you squealed. You’d been unable to differentiate the pleasure and the pain earlier, now you knew the sensation thrumming over your clit was simpler than that - it was raw hot overstimulation.

“Do you know why you’ve been bad?” Came his rumbled query, breaking your spiraling thoughts.

You nodded wildly, making low, keening noises as you tried to steady your breathing, unable to quite comprehend the overwhelming sensations accosting you.

“So tell me then,” he prompted.

Your brain was scrambled, buzzing like static, like the vibrations stuffed between your thighs. You tried to speak but found that your tongue was tripping over the vowels.

“T-uh-touching my…-hah-myself without your -hnng-…permission,” you managed to choke out around involuntary gasps.

“That’s right,” he agreed, rubbing the vibe in slow swirls up and down your aching pussy, watching the hard silicone push against your puffy mound between his fingers, spreading the bubbles of slick there. “And what do you say?”

Oh, I’m sorry sir, I’m sorry, I couldn’t help it,” you cried, “just needed you so bad and I-i-….”

Your voice trailed off when his slow rubbing paused, leaving the fat head of the vibe pressed firmly against your clit instead. It rumbled in an incessant and furious buzz that had your toes curling against the sweat soaked sheets until they ached.

“So it’s this little pussy, huh? Is that the problem? So goddamn needy…” He murmured, thick fingers of his spare hand lowered to tuck beneath the head of the toy. Two digits slipped up through your folds, so wet that his digits met zero resistance when they pushed inside. “And you just do whatever she says brainlessly - is that right?”

His thick fingers curled, stretching, beckoning. You felt like silk beneath the rough press of his digits, like hot wet satin clenching around him.

“Oh god… ‘m gonna cum again ‘kuna…”

You swallowed hard, jaw slack and body curled over as you watched him grind the vibrator over your swollen pussy, vision beginning to blur at the edges, tunneling until all you could see was the obscene sight between your thighs.

“Oh,oh… oh…” You chanted in a breathy mantra, eyes half-lidded and glassy, locked on the veins jumping in his toned forearm.

“So fucking do it then.” He demanded. “Cum around my fingers like the little slut you are.”

That did it - his harsh words alongside the sight of him taking you how he pleased sending your pussy into a fit of frantic pulsing throbs. He worked you through it, squeezing against the tight clench of your walls as you desperately milked his fingers.

“Forgetting something?”

You licked your lips, sure that you were drooling through the white hot pleasure sizzling over your skin, quickly turning to delicious relief when the vibrations finally ceased.

“Thank-thankyou, sir…”

You watched through half lidded eyes as he lifted the sticky head of the vibrator away, though your blissed relief turned quickly to confusion as his palm slipped into view in its place. It raised, as if in slow motion, and then came down against your drooling pussy in a single sharp hit. Before you could quite fathom it, he had repeated the motion - slapping your messy cunt in three more swift strikes.

You choked out a staggered sob when he replaced his fingers again with the firm press of the wand. Hot pain seared up your thighs, over your swollen folds and rubbed raw clit - or god, maybe it was pleasure. You really weren’t sure anymore. All you were certain of now was that you were crying - thick salty ears carving hot paths down your sweat strewn cheeks. You tried to catch his eyes through the blur of tears, sniffling between strangled moans.

“Please sir, please pleasepleaseplease…” You babbled, stuck in a perpetual loop of begging as you shook your head, the motion entirely instinctual.

“Please please please, what?” He echoed, voice pitched high in a mimicry of your feeble babbling, though the last word dropped low and piercing.

“Please sir slap my needy pussy again?” He prompted cruelly, mockingly. “Or please sir make me cum some more?”

You were shaking your head more incessantly now, a firm purposeful motion that felt as though it might leech all of your remaining strength.

“Please s-stop, ‘s too m-uh-uch!” You sobbed out a garbled slur of words, brain well and truly fried.

No.” Came his sharp denial, and he pressed the vibrator harder against you, watching the way your thighs began to tremble. “You’re the one who wanted to cum, right? Wanted to play with your little toys while I was away?”

His wrist moved furiously - coaxing at that silky little spot deep inside, bruised now beneath his attention. Those calloused digits massaging your insides incessantly alongside the unending buzzing vibrations had you shaking, babbling nonsense and swatting feebly at his clenched forearm.

“So now your greedy little cunt is gonna take as many as I give it, cum as many times as I tell it to - and you’re gonna thank me for each and every one.”

Then you felt it - a familiar aching pressure beginning to build beneath the numbing hum of the vibrator, body pushed closer to the limit with each curl of his fingers. Your eyes shot open, wide and blinking away hot tears, desperate to catch his gaze.

“S’kuna hnnn-…stop, really. Think ‘m gonna-…” You cut yourself off with a strangled grunt. Your body suddenly felt limp, heels digging into the mattress to ground yourself as best you could around the pry of the spreader bar.

“Gonna what? Gonna piss yourself?” He sneered, and despite your whining, neither his fingers nor the press of the vibrator eased.

You watched him work your sloppy pussy with unfocused eyes, vision glassy and vacant as the mounting pressure became suddenly overwhelming.

“Go on then. Do it, brat. Soil yourself,” he hissed.

At the mere sound of his cruel words, the dam broke - a hot slick gush between your wobbling thighs alongside a wave of relief so intense that it was dizzying. You slumped forward, curled in on yourself. Panting between broken sounding moans and shuddered breaths - weeping pathetically as you tried to tug your knees together - leather straps still biting at your ankles. He didn’t waver, the vibrator remained locked against your twitching cunt despite your writhing.

“Look at you. Can’t even control your own fuckin’ bladder.” Sukuna spat and slipped his soaked fingers from you, smearing your mess over your folds, sticky and glistening wet, still burning hot from where he’d slapped you raw. “Squirtin' all over me. Filthy fuckin’ girl.”

You mumbled something then below your breath, an incoherent string of babbled pleas in response. When you dipped your limp head and said nothing else, he raised a hand and tucked it beneath your chin, lifting until he could see your face. He cradled your heated cheek in his big palm, and his expression softened an inch when he caught sight of you. Your cheeks stained with streaks of mascara turned to liquid coal, your own spit, snot, and tears smeared messily over your face.

“Cum for me one more time now sweetheart, and we’ll call it even, okay?” He murmured, voice entirely void of its previous heat. His thumb rolled in soothing circles over the hinge of your jaw as you squeaked out a spineless little sound and began shaking beneath him - another weak orgasm wracking your body.

To your bodies utter relief, the vibrations lowered steadily in the wake of your nth orgasm until the buzzing hum ceased entirely. The entire stretch of your inner thighs, alongside your abused pussy was a heady cocktail of numb and entirely oversensitive - like he’d peeled your skin off and you were left with only the bare nerve endings beneath. Even the kiss of the cool air had you wincing.

“‘Kuna ‘m sorry… ‘msosorry, please don’t be mad at me anymore…” You cried, full body sobbing now. Sucking in heaving, labored breaths through the tears streaming freely down your flushed cheeks.

In the next breath he’d snapped the leg restraints from your ankles, rubbed hot and raw from the bite of leather - and before you could utter another word he’d tugged you up into his lap, and you found your head pressed firmly against his chest. You felt suddenly unimaginably fragile, nuzzling into the swell of his pecs, and you turned your head inward - nose stuffed into his shirt, breathing deeply.

You stayed there for a good while with your eyes squeezed closed, listening to his steady heartbeat thrum in your ear. His hand traced slow soothing shapes down your spine, breaking every so often to instead pet at your sweat slicked hair, until your breathing slowed and the fog plaguing your head cleared an inch.

“I’m getting you all dirty.” You finally mumbled into his chest, sniffling a little, desperate not to get snot on him alongside the plethora of other bodily fluids you were currently soaking him with.

“Don’t worry about that, doesn’t matter,” he murmured, nosing delicately at your hair, “you okay sweetheart? Went a bit hard on you.”

“‘M okay,” you mumbled into the damp fabric of his shirt, “I deserved it.”

Sukuna pressed a slow kiss into the crown of your head, and you felt him pause there for a moment to inhale your soft scent.

“Still,” he continued, voice a gentle rumble, “You know you’re my good girl, yeah? I’m not really mad at you.”

You nodded, and despite the exhaustion and pain you knew his words were true, and the sentiment made your chest ache.

“I know,” you sniffled, feeling another wave of tears begin to well at your lash line, “love you.”

“I love you too, princess. You did a real good job for me. Let’s go take a bath, yeah?”
