"Happy Birthday"
You mutter it to yourself, smearing icing on your own cake. For the fifth year in a row you are making your own cake because your partner "forgot to order one for you."
You try to stay positive, focusing instead on how hot you look today in your new skirt and strappy little tank top, checking your reflection in the glass of the cake stand as you cover the lovely treat for later tonight.
As usual, you are the only one who requested the day off for your special day, and spend most of it lying around doomscrolling on your phone, waiting for your partner to be home from work. It's hours before they finally make it home, and they barely mutter a "happy birthday" to you, handing you a small box that's not even wrapped, before flopping noisily onto the bed.
"I just need a power nap. I'll be up and ready to go out soon."
They're snoring within minutes and you stomp your foot in a huff before stalking back to the living room. You look down at the little box in your hands.
At least they remembered to get me something this year...
But what kind of box doesnt have a hinge or a lid? It was a patchwork of different wood shapes inlaid together into a seamless rectangle. Something is rattling around inside. You flip it over, looking for a hint as to how it opens. Nothing.
Ugh, happy birthday to me I guess.
You toss it onto a shelf and lie on the couch, there's an infomercial about a toaster over that also roasts whole chickens. Sounds like the perfect thing to disassociate to for the rest of the evening. You fall asleep within a half hour.
You see the box in your dreams, its glowing and pulsing on your shelf. You watch one corner in particular shaped like a small triangle light up brighter than the rest. The corner pulls open on it's own, and you watch the box slide open.
********HAHAHAHAHA!*******
A menacing laugh fills your head, startling you awake. You flop onto the living room floor in a heap. It's pitch dark, so you grope for your phone to check the time. You slump when you see that your birthday has been over for 45 minutes. When you march to the bedroom, you see your partner still passed out on the bed, practically in the same position from when you left them earlier.
"UGH!"
This time you announce your disgust as you stomp back to the couch.
"Whatever! Guess my birthday isnt something to even celebrate."
You feel bitter and disappointed...and hurt mostly. What was the point of requesting the day off work just to be cute around the house for nobody? You're about to lie back down on the couch when something catches your eye:
There's a low humming coming from the little box on the shelf.
You stare at it in disbelief. No way it could be the dream still. You're very aware of how cold the floor feels under your feet. So...why is this the same setting at the dream you just woke up from? The box vibrates now, like it was receiving a text message. The familiarity of the sound makes you feel slightly less afraid and you reach for it...You find the slightly darkened triangle of wood that makes up the corner on the lid. Just like in your dream. Your mouth feels dry and you hold your breath as you take the little piece between your fingers, and feel the lid sliding. That's when the floor beneath you opens up, and swallows you into darkness.
You land hard, but surprisingly without the pain of impact. Still the air takes time returning to your lungs as you check your surroundings breathlessly.
"Well, well. What have we here? Another visitor?"
A deep voice penetrates the pitch darkness. You hear the clap of someones hands and directly before you, that same aura emitted by the box moments ago fills the space around you. There is an immense presence, you see a tall shadow approaching you.
"I am Ryomen Sukuna. And you have trespassed into my domain. State your purpose, little fool."
His eyes glitter dangerously as he leers down at you. His chest is completely bare, but he still wore a silvery white kimono gathered by a jet black obi at his waist.
Oh, god, he must've been changing.
Your cheeks burn in embarrassment. Nevermind the weirdness of the situation, you were usually the one to enter a room only after knocking first.
"I'm so sorry! I have no idea where I am or how I got here."
That answer didn't satisfy him one bit.
"So you're barging in on me 'by accident?' How annoying."
Annoying?! He has some nerve.
"Hey! I just apologized! Believe me, I was just sitting at home a second ago being bummed out about my crappy birthday that apparently only I care about. So sorry to be inconveniencing you!"
His eyes widen in shock at how bold your words are. Now he grins at you, and there's alot of menace behind those teeth.
"Ha! A fiery one arent you? And it's your birthday? Thats cute. What's so crappy about it? Didn't get the pony you asked for?"
"No, actually I got you as my gift," you huffed.
"And that's all I got by the way."
Now he looked even more amused.
"Haha! What? I'm your gift? Someone gave you a fragment of my soul for a birthday present and you sound more than a little ungrateful. You have no idea who I am..."
There was another thunderous clap of his hands and the cavern around you illuminates.
You recoil in shock as you realize you have been standing among the scattered remains of thousands of partial skeletons. A mountain of them made up a throne where he must have been before you arrived. His face becomes clear to you. Your breath catches in your throat when you see his second set of eyes, locked onto you from his high sitting cheekbones. His hair is a dusky pink and you notice that his face is adorned with an inky black tattoo framing his features dangerously. The same patterns trail down his chest and shoulders. Dark black bands on his skin met his wrists, and wickedly dark nails adorned each fingertip.
"I am the god of curses and all poisons. Ryomen Sukuna."
His words shake the world around you, and you feel fear welling up inside of you. You wonder if you will make it home ever again, and can't prevent the tears from forming in your eyes. You finally understand that this definitely isn't a dimension from your time. You are completely at his mercy here.
"P-please...I just wanna leave!" you stutter.
"That's much better. That's the face I wanted." He chuckles and eyes you up and down.
"But before you go, let's get another look at you."
His voice was less stern, and he was staring at the pleats in your skirt.
Or rather at your bare legs.
"You know, you're alot cuter than the ones who normally show up here requesting my favor...Doesn't usually go so well for them."
He chuckled, but you sense the malice behind his words. You glance down and wonder how many of those previous visitors were still lying around.
"Hey now, dont judge me too harshly. It's not often I have a reason to pick up around here."
He claps his hands once and the mess of remains vanishes, replaced by a brick room with an enormous roaring fireplace. You take note that the carpet is still a deep bloody red.
Must be his decor style, you think to yourself.
"So is this what you humans are wearing these days? Not bad."
He takes a step and reaches toward you, you freeze. He touches the thin shoulder strap of your shirt, snapping it against your skin playfully. You feel your face getting hot, but can't step back, knowing full well you should. The way his eyes are looking at you makes you feel vulnerable, but something stronger than your fear holds you in place. Maybe it's just having someone noticing the effort you put into your outfit.
Oh, god. That's kinda pathetic, you gripe to yourself silently.
You find yourself staring at his lips, noticing the sharpness of his fangs. You wonder how those would feel sinking into your most sensitive spots.
Stop that! He just admitted hes a killer!
You start looking around for anything that resembles an exit, but the feeling of his thumb brushing against your nipple through your shirt makes you jump.
"Wait!"
Your arms raise to cover your chest, but he doesnt remove his hand, the pressure of your arm only pins his fingers in place.
"I can't, I have someone who is going to be looking for me soon."
He laughs and presses his thumb in firmer against your nipple, making sure his nail pinches it. The pain twinges and your knees feel weaker.
"No worries, little cutie. Time passes alot slower in here. No one will know you're gone for more than a few minutes. Even if you stay for days..."
He let the idea linger in the air, an open invitation. You bite your lip, still worried about if your partner rolls over in the middle of the night and finds you missing. But then again, their comments and attitude from earlier are still fresh in your mind.
Besides, they're making this guy look like fantastic company by comparison..
Did you really just think that?
You meet Sukuna's gaze again, his eyes pierce you. You still can't help but feel like a tiny mouse about to be devoured by a hawk. This time all you can manage is to slightly shake your head. He chuckles and pulls his hand back obediently. He circles you slowly, this time brushing some of your hair off your shoulder.
"Someone sure has a hold on you, for you to behave so obediently," he pried.
That comment makes you simmer a bit. Bastard.
"Well, I hope a sweet loyal plaything like you is at least being well taken care of..."
his voice trails off, and your eyes turn directly into the fireplace.
Your jaw is clenched. He watches you weighing your options in your head. You feel the tips of his nails slide down your bare arms, making you shiver.
"Don't you ever get tired of being good? Don't you ever wonder what it would be like..." his hands grip your waist now, and you feel the urgent press of his hips against your ass,
"To break every rule?"
The breath you'd been holding releases in a deeper sound than you had intended. He laughs at that break in your silence.
"You see? You want this."
His mouth is warm against your neck and his tongue circles your ear. There's a buzzing from your spine down to your toes. Now you squeal, and feel the exhale of him chuckling against you.
"Naughty..."
His hips press into you again, reminding you that he is rock hard and practically pushing up your skirt with his erection.
"I thought you'd need a little more convincing."
You hear him, but can't respond as you feel his warm, bare chest sliding down your back, his mouth licking and biting you all the way down. He nips your ass when he pulls up your skirt, and with a strong hand, he spreads your thighs.
"No wonder, just look what you wore for me!"
Your face burns, you had been wearing your lacy pink thong for your partner, before they had forgotten about your date night. That annoying thought vanishes immediately from your head when you feel your underwear being slid to the side and the warmth of his tongue lick you from behind. He moans into you,
"So sweet...fuck it's been an eternity since I've gotten to taste such a treat."
His tongue presses into you again, you lose balance and have to catch yourself on your hands, leaving your ass in the air. Rather than help you stand his arms wrap around your back, holding you locked into place as he continues. He either doesnt know or doesnt care that the new position makes you feel slightly embarrassed. He laughs from between your thighs and you feel his teeth biting into you. You scream in a mix of surprise, pleasure and pain, wondering briefly how rough this is going to be.
"This is going to take a while. I hope you didnt make plans today, my new little plaything."
His tongue presses into you again, firmer, sweeping low to circle all of you. You feel the pressure of one of his fingers sliding into you.
"Ahh!"
The combination of his tongue and his touch make you squirm.
This is crazy! You just met him!
You try to convince yourself momentarily that you should stand upright and try to find a way out, then your eyes land on what had been pressing into your ass before.
Oh, god.
Just the outline of his erection through the silk of his kimono was demanding your attention. He was enormous. Tentatively, still trying to keep your balance on one hand, you dare to reach back to give him a firm squeeze. He hums deeply against you, his hips push roughly into your hand, encouraging you for more.
"That's good. You really want it?"
He reaches down to loosen his obi, allowing the rest of his kimono to fall free.
"Don't worry, we'll get you ready for it first," he added with another low chuckle.
Your eyes widen in disbelief when you see him. He allows you to stand up finally so you can turn around and sit in front of him. He rises onto his feet so that his thick cock is in front of your face. The sheer size of it leaves you speechless and staring dumbly. It had to be 6 inches around! There are markings on the underside that match the ones on his face and body. Your mouth hangs open and your eyes are still wide. Sukuna grabs your chin between his fingers and gently pulls you in closer.
"We both know you want it. Be good, let's open up a little more? There you go."
He grips his shaft in his free hand and rubs his tip just between your lips. Instantly at the taste of his skin, your eyes get heavy and you begin to feel hot all over.
Oh, my god. I'm really doing this.
He slides his fingers through your hair, using it to pull your mouth over more of him.
"Mmmmmmm, yes more like that. You're doing so good."
Your heart does a little flutter at his praises, you find yourself wanting to do a good job for him, and start your own rhythm. Eventually he lets go of your hair and you keep going.
"I knew you'd be good at this. As soon as I saw how cute and innocently you dressed yourself."
He groaned and pushed his hips to meet your mouth. The hit to the back of your throat makes you gag, but you dont stop. Your jaw is tired already from the sheer size of him. He leans over you and you feel his hand sliding down your stomach.
"Now, let me change your world, my sweet little doll."
His palm is so warm between your legs. You moan against him, still lost in your task when you feel something warm lick from his hand. You cry out in surprise, pulling back and looking down in alarm. There is a mouth in the palm of his hand, greedily lapping at you. You look back up at him, bewildered and still panting slightly.
"You love it, don't you? Come on, don't leave me to play by myself."
He strokes himself in front of your face, letting it rest on your cheek momentarily.
Fuck its bigger than my whole face!
You squirm on his hand and open your mouth as wide as possible for him. He hisses through his teeth as he takes your mouth, rougher this time. His hips buck, bruising the back of your throat, but all you can do is bounce your hips onto his mouth-hand and accept his brutal pounding gratefully.
"Fuck, your little slut mouth is going to make me cum already."
He starts to pull back from you, but your arms wrap around his ass, locking him into place.
"You want it that badly?" he purrs.
"I wont tell you no."
His fingers slip inside you, continuing your sweet torture with his second mouth. This time when you groan, his other hand seizes your hair, pulling your lips onto his hard cock all the way. You try to hold still without air, and feel the warmth of his cum filling your entire mouth. He lets you go and you sputter off of him finally, gasping for breath and choking. A thick white dribble runs down your chin and onto your shirt.
"There, there,"
You hear him soothing you, and feel his hands on your bare shoulders.
"You did so well, I think you deserve something that actually celebrates you on your little birthday."
His strong hands guide you onto your back. With his face so close to yours, you cant resist your urge. You slip your arms around his neck and place small begging kisses along his jaw, tracing his strange markings with your tongue. A deep resonating growl escapes from his throat, and he meets your gaze as he presses his lips into yours. A now familiar feeling of his second mouth opening in the palm of his hand against your inner thigh makes you whimper in excitement.
"Oh, fuck," you barely whisper.
This time, you feel the sensation of teeth lightly nipping and biting you and he slides his hand up. There's an intense warmth as his breath washes over you, causing you to shudder. Sukuna repositions himself between your legs and sinks down to place more open mouthed kisses to your other thigh. The sensation of having both sides stimulated makes you moan deep and long.
There's a tug, and a rip with the removal of your underwear.
"Hey! I liked those!" You protest with some seriousness in your voice, but it still turns you on to see how impatient he is with you.
"You're so sweet," he murmurs again into your core, making your eyes practically roll back.
He keeps saying that...and you start to believe him.
You arch your back into his hungry mouths, both of them. They suck and kiss you slowly at first, matching your pace. Then an embarrassingly loud yelp blurts from your lips when both of his tongues find your most vulnerable spot at once. His thumbs stretch you gently, coaxing more sounds from your throat. Your hands find their way into his hair and down his neck. Daringly, you stroke his lower lip with a fingertip. He sucks it greedily into his mouth. Out of curiosity, you do the same to the mouth on his hand. It does the same. Sukuna rumbles from on top of you in bemusement.
"That's right it's the same me there too. Hehe"
Suddenly both of his mouths bite into your thighs painfully, forcing a surprised scream from you. Then you feel his wonderfully gentle tongues licking slowly over the bite marks, making you swoon again, all before another painful round of bites to create a cycle of your sounds. You writhe pitifully and whimper for his mercy, praying he will stop and not devour you whole, you didn't doubt he would if he so wished it.
You barely register than he is rising up above you, flipping up the hem of your skirt, reaching down and positioning the engorged tip of his cock, letting your eyes lock onto his as he spits into his hand and prepares himself for you.
"You can set your pace here," he croons into your ear.
"See how much you like it."
His voice is so warm and encouraging, it makes your hips roll toward him, letting the first precious inches of yourself be explored.
"There you go, easy, right?"
He nuzzles your ear, his tongue venturing a little farther than you've ever felt someone go.
You're dimly aware that he is lacing his fingers into yours and raising your arms above your head.
"Now for the fun part,"
His tongue finds your neck, then his teeth sink in, making you flinch suddenly. The movement makes you slide further down his length, stretching you to match his girth.
Oh, fuck!
Every movement sinks him into you. You almost panic that he's too much, and try to pull your hands to push him up. His strong fingers lock yours into place, gripping your wrists firmly, but with no actual force.
"You can do it," he chides to you, genuine encouragement in his voice. "If it's what you want, you'll manage it." He adds devilishly.
The way his eyes are studying you, interpreting your sounds and movements, you realize he is wanting you to do it yourself. It's easier for you, trusting he will hold still while you adjust. You take a slow deep breath, and allow yourself to accept more of him.
"See? I knew you could," he purrs against your throat, letting the smallest of your movements rock you together.
You let him slip into you all the way, your mouth widening in surprise at how little pain there is despite his size. Your sounds escape and he groans in unison with you. He moves slowly first, much to your gratitude. After a few agonizingly deliberate strokes, Sukuna lets go of your wrists, focusing instead on pinching your nipples through the fabric of your thin shirt. He is still muttering to himself in what sounds like disbelief,
"So fucking, cute..."
Suddenly he thrusts into you with strength, milking a deep resonating moan from you. The mouth on his right hand closes around your nipple, teasing you with achingly sharp teeth and his warm tongue.
The sensation makes you flinch and buck against his hips, and with each thrust, he drives you back and forth between the extremes of pleasure and pain. Your nails dig into his shoulders, and you wrap your legs around his waist. Try as you can to meet his hips when he comes crashing down upon you. The most embarrassing little yelps you've ever made spill from your lips.
"Fuck, you've got some life to you!" He hoists one of your legs up over his shoulder.
"Scream as loud as you want, little lamb. Nobody can hear you but me."
He reaches down to caress your cheek, but you open your mouth in time to lick one of his fingers. Now it's his turn to make an ungodly sound, and you feel the palm of his hand split open against your lips in a kiss that also seals your mouth shut.
Fuck me...
You suck on his tongue, your hips bouncing the entire time, begging for more of his sweet torture. It takes you a moment to realize he's stopped moving and you are sliding up and down the length of his shaft almost easily on your own.
With a sudden, strong grip, Sukuna releases your face and ends your kiss. He falls in reverse, pulling you by your hips until you are on top of him
All of his eyes are heavy lidded and he pants as he realigns himself to penetrate you.
"Let's see what you do with it now."
The change in his angle makes your mouth hang open when you feel him sheath himself inside you. You close your eyes, sighing deeply as you raise and lower yourself over him again, and again. Leaning back on your hands, you bite your lip and meet his eyes again to make sure he is watching you. He is. It's your turn to smirk now.
"Wanna see what I can do?"
He nods, mutely. You increase your rhythm, little by little, forcing his engorged head up against your g spot. One of your hands slips between your legs, you notice his lower eyes are following your hand, while his main eyes are locked on your face. You bite your lower lip, loving his intense attention.
Watch me closely...
You bounce on his cock faster, with more urgency and your hand matches your pace as well. Sukuna's mouth hangs open, and you watch him lick his lips with wicked intent. Then you find your release, your ecstasy gushing over his burning skin. You clench around him violently, and suddenly neither one of you is very dry anymore. You vaguely hear his voice with your heart pulsing in your ears.
"Ohh, fuck..."
His hands lock your hips into place, and he fucks you with much more urgency now. His nails cut into your lower back, he pulls you down to suck and bite on your chest with ferocity. You hear his moans rumbling deep and animalistic in his throat, vibrating against your skin.
Fuck me! Ruin me!
You yelp pathetically, still weak from your orgasm and unable to hardly keep upright against the onslaught. You surrender to his thrusting hips, throwing you back and forth violently. Your insides are sore and rubbing painfully against him now. You grit your teeth and at first clench your eyes shut, but can't resist watching his hypnotic crimson eyes burning into you.
With a sudden fluid motion, he withdraws from you, making you gasp in instant relief. But before you can close your mouth, you feel his hand close around the back of your neck. You hear him mutter something that sounds like "happy birthday" and he fills your entire mouth a second time, cruelly jamming his head to the back of your throat to make sure you choked a bit.
Dick! He loves doing that.
Coughing results in a sticky mess dripping down your chin and onto your skirt. It's safe to say your cute outfit is pretty wrecked. You wipe your chin and glare up at him. But there's a pulse between your legs that cannot be ignored.
He kneels to meet your gaze and smirks at you, running his fingers through his hair. He's still glistening in sweat and out of breath.
"Be honest. Did you hate that?"
You sit in silence, your knees drawn together cutely in your cum stained skirt. You're out of breath still too.
"...no."
"Then you should really come by more often." He holds his hand out to stand you up. With a snap of his fingers, his kimono from before appears over his arm. He drapes it almost apologetically around your shoulders. Almost.
"You owe me a new outfit," you grumble.
He laughs at your accusation.
"Oh yeah? And where do you suggest I shop for a replacement here in my domain?"
"So your powers are limited? Can't do simple clothes? That's what I thought." You mutter in spite.
He sighs and snaps his fingers again. A long black box appears on the floor at your feet.
"My, you're needy. Fine, it's the least I can do I suppose."
"And...can I get back to my world and my time now too?"
This time he frowns.
"Leaving already?"
"I told you I have my own life going on. I can't stay here forever. Tempting as it is." You smile so that he knows you want to return.
"As you wish. Next time you feel like dropping in, just knock first. I could have been naked you know."
You laugh and he pats your head. He leans in, at first you think for a kiss and lean in as well, he grips your chin instead.
"Next time, no underwear."
The last thing you feel is the warmth of his tongue on your cheek. There's a light buzzing feeling all over your body that you can hear.
Bzzzt
Bzzzt
Your eyes snap open. You're on your couch in your living room.
There's a man on tv who is visibly drunk and screaming about how wonderful his pearl handle pocket knives are. You remember passing out after your failed birthday plans, and disappointment almost makes you sick to your stomach.
Rolling to your feet, you grab your blanket off the floor and start to shuffle off to bed.
"Ow!"
Someone left something on the floor. You squint and barely make out the shape by the tv's light in the pitch black.
You're left breathless when you recognize a familiar black box.
Sukuna.
The memory of what felt like a dream comes rushing back to you. You're fumbling noisily with the lid, praying it isnt another fucking puzzle box. Luckily, it isnt. There's a dark tissue paper obscuring what's inside. Your heart is hammering in your chest when your fingertips feel cool silk.
"Ohh, it's a kimono!"
You squeal with joy and pull it closer to the light to trace over its patterns and folds. You make a note to think of some way to thank him the next time you see him.
The next time you see him.
The words echo in your mind.
When you creep quietly into bed, you tuck the gorgeous gift into your pillowcase. You drift to sleep with your fingers lovingly stroking the silk, reminding yourself of the best birthday you've ever had.
