The 28th day
She’ll be bleeding again
And in lupine ways
We’ll alleviate the pain
Annoyed. Sore. Hungry. Sleepy. Everything all at once. What a pain.
Your period arrived precisely before classes started. You always kept your monthly products on hand so that was never a concern. The real issue, your true enemy were the cramps. The bane of your existence. You hoped they wouldn’t hit as hard as they did during classes, mentally scolding yourself for not bringing some kind of painkiller. It was unbearable. So, you did the only thing your frazzled mindset could do: leave the campus. College can wait. A warm little cat nap was far more important.
Taking a taxi because God forbid anybody even glances at you wrong in this very moment, you arrived home. Shedding off your white tee and denim pants to a more comfy and loose black shirt with baggy gray sweats. You got ready to curl up in bed only to realize you no longer felt sleepy. Instead, you hunted down some painkillers to at least ease up the cramps.
Lo and behold, nothing.
A loud groan escaped you, but you opted to put up with the pain as self punishment for being forgetful… also you didn’t want to go to the store. Perhaps this’ll be a good reminder to your future self?
You began to scrounge the cabinets for some snacks- ping!
A message came up on your phone with a small picture of a cartoonishly pink and angry tiger; it’s from your favorite next-door neighbor and childhood best friend. Who was supposed to be in class right now…
[Sukunyan: You home?]
You smiled fondly at the notification. You knew he was home today. He refused to attend classes because of a video game he’s actually excited about was releasing today. Which was rare for Sukuna. Not the ditching class part— the excited part. Nothing ever truly excited him.
[You: Yeah, I left early]
[Sukunyan: Goody two-shoes cutting class?]
[You: You’re so annoying]
[Sukunyan: Nah, you are. Come over, I made food.]
[You: …how’d you know I was hungry?]
[Sukunyan: When aren’t you?]
He can feel you roll your eyes through the phone. He also knows you’re smiling. He simply knew you all too well, and he loves it. Not that he’ll tell you, of course.
[Sukunyan: Stop rolling your eyes.]
[You: Shut up]
[You: …Be there soon]
You stretched out your tired body while trying to ignore the cramps as best as you could before you gathered your keys and phone, heading over to the next house and knocking on his door. He opened up in no time; greeting you with his pink hair pushed back laying softly over his dark and slightly outgrown undercut, tattoos recently cared for, his typical all black, comfy shirt and sweats, smirking as always.
“Damn, that hungry?” His smirk widened to a mischievous grin when you pushed past him, playfully scoffing.
“Like I don’t live two feet away from you, dick.” You grinned back at him as he closed the door, watching you. The scent of his superb cooking hit you hard, mouth watering as you see the perfectly grilled and seasoned shredded wagyu sitting on rice and a soy marinated soft-boiled egg next to the meat. Sukuna, the absolute darling he secretly is, already plated both of your meals into bowls. You grabbed both and entered the living room seeing he already settled himself back on his couch, you noticed he brought out a blanket that was set on the side for you.
“Such a sweetie~” You teased him placing your bowls on the coffee table in front of you next to the hot tea he made for you both and sat next to him, digging into your food.
He scoffed reaching for his bowl, “You’d complain if I didn’t, you brat.” He knows you like to cuddle up with a blanket on the couch. Mouth stuffed, you smiled with two grains of rice stuck to your lips. He side-eyed you seemingly unamused but deep inside, he was filled with pride knowing how much you loved his cooking. You both quickly devoured the food, downing the tea that was no longer steaming and piled the empty bowls on the coffee table. You grabbed the dishes returning to the kitchen, blanket wrapped around your shoulders comforting and started washing the dishes. Sukuna protested you cleaning but you ignored him. He came up behind you, placing his chin on your right shoulder, glaring at your hands.
You smiled softly at him, “Suku, it’s alright, I don’t mind.” A small pout etched his face as he simply grunted in response, his arms circled around to grab the bowls from you and cleaned. Your hands awkwardly placed on the sink not knowing what to do with them, feeling his warm body pressed against your back. Hot breath fanning down your chest.
Moments like these remind you of why you fell so deeply in love with this man back when you were dumb preteens. His selective compassion, his humor, his need to take care of you. The love only grew stronger with time. You’ve avoided confessing to him solely out of fear it could ruin your friendship with him. Sukuna being your longtime friend, you didn’t want to lose him over feelings he most likely didn’t share. Also, definitely didn’t help the hopeless romantic in you hearing your other friends tell you to, ‘never fall for your best friend.’ You never listened. He was sweet when he wanted to be, surprisingly gentle. Romantic. Many things no one else got to see. He had a hard time opening up but you were one of the few who understood him perfectly, who he didn’t need to hide from. Well, that’s exactly not true…
Sukuna finished up the dishes and nudged his head into yours, “Good thing I cleaned, you’re terrible at it.”
“Shut your ass up.” You mumbled before grinning at him as he returned the expression and pulled away from you, going back into the living room. Your body felt cold, it lacked him and his incredible warmth. He picked up the controller and unpaused his game, while you curl back up laying on your side. Your cramps started acting up again and you hissed, cocooning yourself with the blanket further. His hand grabs a hold of your ankles, bringing your legs to rest on his while exposing your legs from under the tender cover. He felt you lightly tremble.
“Aww, is the little baby cold?” He coos with a mocking pout.
“You’re annoying.” You grumbled softly, still maintaining the air of playfulness. He smirked down at you, returning to his game. That’s when a jolt of pain shot up as it felt like a knife twisting sadistically in your uterus and you winced, curling up even more. “…you happen to have any painkillers?”
He eyed you briefly and shook his head, concentrated in the story of his current interest. “Do I look like a guy who needs it?” You rolled your eyes at him as he continued, “What for anyway?”
“Got my period today. My cramps are trying to end my life.” You groaned out.
“You’re on your period?” His voice nearly betrayed him— almost tossing his controller with complete disregard of the game he was enjoying. He sounded excited. And nothing ever excites Sukuna. He felt his hands dampen, his heart rate picked up and felt the heat travel his skin. His eyes sparkled with joy as he fought off a grin, but you never noticed it. Typically, you avoided going out all together during your monthly torture so this was new for him.
“Yep, and now I’m here— suffering.”
“Ah, so that’s why you skipped class. Here I thought you were finally joining the dark side.” He placed a hand on your hip to massage it lightly as he teased. Feeling the plushness of your flesh. His warm hand was a welcoming for you. The two of you often touched each other in similar ways but never was it beyond platonic. It’s what best friends do, right?
You chuckled softly still wincing but managing the pain, “I’m not paying those classes out of pocket for nothing.” He only nodded, wanting to change the subject to something more interesting. So he paused his game, turning to you wide-eyed and interest piqued.
“So, period, huh? You know…” He trailed off knowing exactly where he wanted to take this. His large hand softly rubbing your hip and thigh, warming you up. He swallowed thickly, feeling a tad nervous about your reaction but it doesn’t hurt to offer. He’s only trying to help! After all, what are best friends for? “I’ve heard of other ways to soothe the pain. I’ve been thinking about testing it out. If you’re interested, of course…” His smirk was devious, his tone was mischievous and his hand— warm and damp was gently kneading at your thigh causing a warm ache between your legs but all that you ignored; all to be free from the cramps that wreaked havoc in you.
Sukuna studied your reaction.
“Really? What is it?” Oh, sweet innocent you, how happy you were for relief.
Unholy water
Sanguine addiction
You… weren’t sure exactly how you ended up here seeing as this isn’t what you expected.
The soft and soothing soundtrack of the game he left on pause playing in the background reminded you of his abandonment of it. You asked him if he really wanted to stop playing it, only for him to respond with a simple, “This is more fun.”
Lying on your back. Completely bare from the waist down, Sukuna’s head between your thighs. He grinned wildly, seeing the bloody mess you were. He’s never been harder.
This was new. On so many different levels. Aside from comfortably undressing in each other’s presence and seeing the other half naked multiple times, you two have never had anything remotely sexual, never even attempted to. In fact, you were sure Sukuna wasn’t interested. So when Sukuna gave you the simple offer of relief through sex, and with that warm ache present, you immediately felt the heat pool in your lower belly and agreed. It’s hard to deny a man as attractive as him, especially when you already loved him.
His tongue lapped along your lower lips, tasting the iron on his tongue and you watched.
In shock.
Disgust.
…Arousal? This wasn’t what you pictured when he suggested period sex but his tongue felt like heaven. The warm muscle giving your sex the attention you didn’t realize you craved. He licked slow and lazily from your entrance to your clit. His eyelashes fluttered sweetly: a perfect visual of pink and red from your position.
“I’ve always wanted to do this.” He admitted— his velvety voice laced in syrupy lust. Your hand found its way into his hair, clawing his scalp. He groaned out from the feeling, pushing his face further to get lost between your thighs. His hot breath, the vibrations from his grunts, absolutely everything caused sparks of heat to course through your skin.
“Sukuna~” A moan escaped, becoming overwhelmed by the sight alone. He groaned into your core, his tongue caressing your clit in soft circular motions as his hips grind into the couch with need. He pulled away briefly, showing your blood coated lightly on his tongue proudly. Seeing him like this pulled whines out of you, needing him to give you the painkiller you wanted badly.
He dived right back in ready to devour. “So good for me…” Was all he could say before he pushed his tongue into your entrance. You gasped softly, raking your fingers further into his hair, pulling it enough to make him moan into your pussy more. “Can’t wait to shove my cock in you.” He spoke under his breath. His lewd comments spiked the heat up in your lower belly, a need for more of his filthy words and tongue.
All feelings of disgust and shock go out the window. Leaving nothing but pure desire for this perfect man. For your best friend.
His tongue pushed as far as he could to scoop your bloodied essence and drink from you. He pressed his face firmly against your core, needing to get deeper in you. Sukuna looked up: the sight of your lips parted, panting, glistening skin and heavy lidded eyes were enough to get him feral. He growled, clawing his blunt nails into your thighs and forcing them apart. He wants you to see the mess he’s about to make of you. His eyes wild, appearing mostly black with a halo of red. The two of you stared into each others eyes so tenderly and yet so darkly as he ate you out. His face staining in your blood making him look more barbaric with his hair dampening from the heat created between you. Sukuna pushed your legs towards you, folding you perfectly. He needed you to see more. With his hands pressing into you on the back of your knees, you watched desperately moaning from how he took your clit into his mouth, massaging it with his tongue.
Hey wolf moon, come cast your spell on me.
Sukuna groaned deeply it sounded like a growl, twisting his tongue on your clit, gathering slick and blood to spit back onto your heat. It forced the air out of you, Sukuna grinned, his voice a deep purr, “Bet you’re feeling better already.” Your nodded, the pain has either subsided or simply went ignored; either way his tongue is all you can focus on. “Say it.” He inserts a finger, curling as he shoves it knuckle deep.
“Better- so much better, Suku~”
“Mm, I’ll always take good care of you.” He hummed softly as he fingers you, pressing a kiss to your wet pussy. “Such a good girl for me…” He lapped at your dripping heat. Taking in your lower lips and softly sucking them, he’s giving his attention to every part of your core. Reminding you of the lovely remedy he is. The moment overwhelming for both of you as he slides in a second finger, red staining his fingers making him moan. He began to piston his fingers, stretching you out and feeling the silky sensation of your walls. He watches your blood and slick dripping out, listening to your moans and cries of pleasure with his jaw slack in awe. Feeling a shiver of an orgasm so desperately close to being released, you groaned arching your back and grinding into his digits. Despite this being a first between you two, he could tell; so he slipped his fingers out and sat up while a whine escaped you. “Sorry sweetheart but, I’m gonna need you to cum on my cock.”
You wanted to argue with him at that moment. How dare he ruin this orgasm?! But all that quickly died on your tongue when he slipped off his sweats and his cock sprung out. His length was both surprising and yet not for a man his size. Long and thick, reddened hotly and veiny, tip wet with pre-cum. He looked into your eyes, waiting for you to give him the go or tell him no. He wanted you to be comfortable every step of the way, giving you an out if you needed it and honestly, that alone was hot. You stared at his length hungrily before nodding. He wasted no time slapping his thick member on your clit harshly. You yelped out— surprised by how heavy and hot it felt. He chuckled deeply by your reaction which earned him a pout from you.
“Such a dick.” You couldn’t hide the breathlessness in your voice.
“‘Bout to be your favorite dick.” He slapped it again as you gasped from the sensitivity. He grabbed your legs to wrap around his waist, guiding his tip to your begging pussy, he slowly prodded you. You gazed up at him fully taking notice of his appearance. Sweaty, blush touched upon his ears and cheeks, pink hair sticking to his forehead. His mouth and chin are wet and blood stained with a wolfish grin as some droplets of mixed blood slides down his neck. It was breathtaking. This savage look of his was so fitting for him. The way he stared at his tip disappearing inside of you and reappearing bloodstained was of pure adoration and intensity.
Confident enough that you’ll take him, he pressed his cock forward, holding his breath at the view. Inch by inch, you took him perfectly. Your eyes widening with a choked out moan. His moaned out the breath he was holding just by hearing you.
You were made for him.
He bottomed out and stilled in you, watching your expression carefully to see any sign of discomfort but he was met with the most blissed expression he’s ever seen. He groaned. What a perfect cock sleeve you are.
His hips pulled and pushed lightly, feeling how easily he’s gliding in and out so perfectly, he needed to glanced down. Greeted by the sight of his cock covered in your mixed blood, he grit his teeth and tightened his grip on your hips. His pace picking up as he watched how your greedy entrance swallowed him. The sounds were thick and wet; so lewd you could feel your lust intensify from the noises you made together. Biting your lip, your eyes switched between his face and the way his cock disappeared inside you. You let out a whimper.
“Sukuna~” His name came out in a pant, “You feel so good!” That praise was enough to boost his pace to a near violent thrusting. He slammed his hips into you, punching out the air from your lungs as you can feel him reshaping your insides just for him and him alone. You pleasurably screamed out briefly as he made you into his cute little rag doll, railing you into the couch. Sukuna looked down at his work; marveling the blood splattering in your inner thighs and his pelvis with a devious grin.
“Yeah, just like that,” He grunted out as he pushed your knees into your chest, “Keep bleeding on my cock, brat.” He thumb brushed up on your clit as he railed into you feral-like, he watched you twitch and thrash around from the hypersensitivity.
“Suku-!” You cried out unsure if you wanted his ministrations on your clit to stop, clawing into his wrist tightly. His other hand travelled to your lower belly and pressed down hard enough to feel his cock splitting you in two. Enough to feel how your pussy devoured his length and he loved every second, reveling in pushing the boundaries with you.
He smirked, eyes heavy lidded and fluttering feeling your searing hot walls tightening around his cock. You practically choked him and he couldn’t get enough. Adoring how responsive you were to him, “Nnhh- need you to cum for me, sweetheart. I need it— all over my cock, now.” His demanding voice growled. All you could respond with was a groan that gave a wordless thanks for his mercy on you. He maintained his pace being fully aware that if he threw it off balance, you might not cum. His thumb continued to draw circles on your bundle of nerves, he felt you clench further.
“Ahhhh~! I’m cumming, Sukuna- please- I- mmhhhh!” You babbled out loud and breathless, arching your back and gushing on his dick. Sukuna bit his lip with a whine escaping him, breathing heavily as he felt his orgasm join yours, flooding your pussy mixing in his seed with your essence and blood. He collapsed on top of you still sheathed in. Sweat from you both mixing, you bring your arms around his body to caress his comically sweaty back. Labored breaths were the only sounds greeting Sukuna’s living room.
He slightly pulled away, bringing his blood stained thumb to his mouth and sucked off the red tint as you grimaced at him, he chuckled tiredly, “Don’t get grossed out now, you were down for it.”
“You’re nasty.” A playful glint in your eyes and he matched it.
“Nasty for you.”
“Ugh!” You both laughed at the cheesy response as he pulls out and climbed off to quickly grab a towel, wetting and warming it up in the bathroom sink. He briefly glanced at himself in the mirror, seeing the dried deepened crimson staining his face and fingers. He returned with the towel in hand, laughing to himself.
“I look like I committed a murder-“ He looked down at your blissfully exhausted form, “well, I technically did-“ You kicked his side before he could finish that comment and he grunted lightly with a chuckle. He looked down almost mesmerized by his cum seeping out of you and begrudgingly cleaned his perfect mess off. You couldn’t help but cringe at how sticky you felt. “Mmm, how’s the pain now? Did my little test work?”
You blinked realizing the cramp pains had, for the most part, subsided. “Actually, yeah! Your dick is really a painkiller.” You smirked teasingly as he chuffed at the joke.
“Was trying to get you to squirt but there’s always next time, right?” Sukuna shrugged and smiled innocently, walking back to the bathroom with the dirty towel leaving you wide eyed. Before you could answer him, he called out, “Oi, let’s shower together. Maybe even get a second round in.” You let out a huff but followed after him, removing the remaining clothes off your body and stepping into the shower. Your eyes meet and a sweet smile is shared between you two as you helped wash one another. The proof of your kinky escapade going down the drain, leaving your skin fresh. Soft cloths lathered in body wash gently scrubbing one another. You couldn’t stop staring at him; eyes tracing over his symmetrical black tattoos, spotting every scar on his lightly tanned body while gingerly washing him with the same level of care he did for you.
And he stared at your body with pure adoration, noting and memorizing every little detail. He couldn’t stop staring.
What you didn’t know, is how your best friend felt the same as you do. Down to the bit about his fear of losing you over his confession and not listening to advice from friends that told him not to fall for you. He didn’t listen, and he fell head over heels long before you felt something for him. He fell hard, madly. You’ve been his only love ever since you were kids. Existing in his mind like your were paying rent to live there. But now, things are different. Sukuna finally made the first move, now he just needed you to make the second-
“So, you really want to do this again?” A glimmer of hope could be found in your voice.
“Of course, we should make this a thing. A monthly thing.” He winked and laughed at you as you rolled your eyes and hit his shoulder, then softly massaging the cloth into the spot you hit him with a sweetened smile while muttering about how annoying he is. But he knows you love it.
