sigma pauses mid-adjustment, looking up at you like you’ve said something profoundly incorrect.

“it has to be comfortable,” he replies seriously.

you smile a little. “it is comfortable.”

he hesitates, then nods slowly, as if accepting that this might be a possibility he hadn’t considered. still, he smooths out one last corner before finally sitting down beside you, a little stiff at first like he’s not fully sure what to do with himself now that everything is set.

for a moment, neither of you speak. the wind moves gently through the grass, and sunlight filters through the leaves above, scattering warm patterns across the blanket. somewhere in the distance, there’s the faint sound of water, soft and steady, like the world is breathing quietly around you.

sigma opens the picnic basket carefully, almost like he’s worried something might break. inside are neatly packed sandwiches, sliced fruit arranged with precision, and small desserts that look almost too pretty to eat.

you blink at it. “you made all of this?”

“…yes,” he says, suddenly a little quieter. “i wasn’t sure what you liked, so i made a bit of everything.”

you stare at him for a moment longer than intended, then let out a soft laugh. “that’s kind of insane.”

he stiffens slightly, expression faltering.

“in a good way,” you add quickly.

he relaxes instantly, shoulders dropping as he exhales. “oh.”

you take a sandwich and try it, and sigma watches you closely like he’s waiting for some kind of judgment. you chew thoughtfully, then nod.

“it’s really good.”

his eyes widen just a little. “really?”

“really,” you confirm.

and something in his face softens immediately, like he doesn’t quite know what to do with praise that isn’t tied to performance or expectation. it lingers on him in a way that feels quiet and fragile.

you eat slowly together after that, sharing food from the basket while the afternoon stretches on. sigma stays a little rigid at first, sitting upright like he’s still worried about doing something wrong, but gradually he begins to relax. the space between you shrinks without either of you noticing.

eventually, his shoulder lightly touches yours.

and then stays there.

“do you like this?” he asks after a while, voice low and careful.

you glance at him. “like what?”

“this… date,” he says, like the word itself feels uncertain.

you turn toward him a little more fully. his expression is gentle but searching, like he’s waiting for an answer that could change everything. so you take his hand without hesitation.

“yeah,” you say simply. “i do.”

sigma blinks once, then again, like he’s processing something he didn’t expect to hear.

“…oh.”

you squeeze his hand lightly. “did you think i wouldn’t?”

he hesitates. “i thought… maybe it wouldn’t be enough.”

you shift closer so you can face him properly. “sigma, this is perfect.”

he goes quiet again, the wind brushing through the grass around you as his fingers tighten slightly around yours. for a moment, he just looks at you like he’s trying to memorize the fact that you’re here.

“…i’m glad,” he murmurs. “i’m really glad it’s you.”

you smile at him softly, and sigma finally looks like he isn’t carrying the weight of anything else for once. just this moment. just you.

later, you both lie back on the blanket watching the sky turn warm with late afternoon light. sigma’s hand never lets go of yours, even when you tease him gently for staring.

he flushes immediately. “i’m not staring- i was just-”

you laugh softly, turning your head toward him, and he stops mid-sentence because you’re already smiling at him like that.

“…you’re very pretty,” he blurts out.

you blink, then laugh again. “you can’t just say things like that out of nowhere.”

“why not?”

“because it makes you go red.”

he looks away quickly, flustered. “that’s not-”

you lean in and press a quick kiss to his cheek before he can finish.

sigma freezes completely, like his entire system has stopped working. the wind continues to move through the grass, the sky continues to shift into gold, and sigma quietly realizes that this picnic might permanently ruin him in the best possible way.

Maybe, if you’d had more sense, you would’ve broken up with Naoya in that moment and saved yourself a whole lot of trouble. Instead, just like always, you made excuses for him. You figured he was just having a bad day - that you just needed to prove yourself to him and then he’d be happy to have you as a climbing buddy. 

He was just concerned about your skill. That was all. 

So you’d worked hard at the club - learned plenty of skills, did plenty of hours in the gym, made dozens of friends with the other club members to ensure you weren’t dependent on Naoya to teach you everything. 

You tried to ignore how uninterested your boyfriend seemed in your progress, tried to ignore the way he’d flirt with the other women at the club - you were sure he’d be so impressed with you on your first major outing to Mount Hotaka that he’d forget about everything else and be pleased with you for once. 

That was all you wanted, for him to be proud of you outside of the offhanded thanks he’d give whenever you’d make him dinner. 

Your first trip out to the mountain had several people in attendance. Beyond you and Naoya there were a handful of women from the club who you’d grown close with: Shoko, Utahime and Yuki, and then a few men. There were a couple of older guys you didn’t know very well, and then a few in your age range who had been helping develop your skills - the most notable of that group being Sukuna, who had dedicated lots of time to teaching you knowledge that Naoya had brushed aside. 

It had surprised you at first, that the hulking pink-haired man had any interest in helping you do anything. Others in the club had claimed that he tended to be aloof, harsh and generally unfriendly - and while he was harsh in his teachings, unfriendly was certainly not the word you’d use to describe him. 

He’d gone out of his way to help you, chasing away others like Satoru with the claim that they were ‘too stupid to teach you right’. Spending hours at your side, he’d taught you all you needed to know about equipment, rope skills and climbing. He wouldn’t provide praise unless it was deserved, but once you’d finally started getting things right he’d always made sure you knew he was pleased with you. 

It was praise you were desperately starved for, praise you’d love to receive from your boyfriend, and you were ashamed to admit that Sukuna’s simple compliments lingered in your mind for longer than they should have.

You’d grown rather fond of him since joining the mountaineering club, even despite his somewhat prickly demeanour to everyone else, you felt he was someone you could rely on, someone who wouldn’t call you stupid for asking him questions. Even if he’d sometimes tease you for getting upset or frustrated for not understanding something, he’d still take the time to help you understand. 

Unlike Naoya, who would roll his eyes and once again point out how unfit you were for something as involved as mountain climbing. 

The comparison between the two was something you found yourself making more and more often, eyes straying over to your pink-haired friend when he wasn’t looking, your stomach flipping when he’d speak to you, or when he’d place a large hand on your shoulder in congratulations at a task done well. 

You knew it was wrong, chastising yourself whenever the thought of Sukuna would stray into your mind late at night while Naoya was snoring away next to you. Not only did you have a boyfriend, but you were certain Sukuna didn’t think of you in anything beyond a friendly manner anyway.

So you kept those feelings locked deep within your chest and tried to focus on why you were in the club in the first place - to prove to your boyfriend that you’d make a good partner for his mountain expeditions, to prove that you were worth more to him than being a glorified maid in his house.

The first few hours of the hike, starting in the early morning, had gone by fairly uneventfully. Your training had paid off and your legs felt good as you winded up through valleys and fields, trailing a little behind the group of boys, favouring a slightly slower pace and jovial conversation amongst the girls. 

Despite Naoya’s reluctance for you to join the club, you felt like it was where you were supposed to be. You loved being out in nature - taking in the fresh air and drinking from mountain streams, wandering along with like-minded people and encouraging each other along through the gruelling uphills. 

It wasn’t until late afternoon that things started to get more difficult, with the altitude creeping steadily up, and the group stumbling across snow fields that still hadn’t melted in the late spring air. It was nothing you weren’t prepared for, but with everyone feeling a great deal more tired than they had in the morning hours, the pace slowed considerably. 

A group of the more experienced men ended up going on ahead at a quicker pace, saying they’d get the next big section of uphill completed and scout out a good camping spot for the night, since the plan was to make a summit push in the early morning to watch the sunrise. 

You didn’t mind that so much - you didn’t like the feeling of slowing them down and that arrangement meant that you could keep going at a comfortable pace without feeling stressed about it. The girls you were with were perfectly experienced in their own right, and Naoya had chosen to hang behind with you anyway rather than going on ahead. 

That was a decision that you’d convinced yourself was on account of him wanting to keep an eye on you, but a part of you believed it was really because he didn’t get along with any of the men at the club. 

Or perhaps it was just so he could keep staring at Yuki’s ass like he had been for the entire hike up to that point. 

The next couple of hours were difficult, and everyone grew more withdrawn under the effort of a constant uphill - facing switchback after switchback with no clarity on how far you had to go beneath a freshly settled blanket of fog lowering the visibility. Shoko had been struggling for a while, and after an extended rest on a rock decided that it was best if she turned back and camped somewhere lower in the valley. 

She’d been having issues with her lungs and didn’t think it was wise to keep going. 

At her decision, Utahime also suggested that she wanted to go back, mentioning that she also didn’t feel in the best physical condition, and Yuki insisted on going back with the two of them to make sure they got back down safely. You’d considered joining them, but you were still feeling good both physically and mentally and were keen to continue upwards towards the peak. 

Considering Naoya’s experience, you were certain that the two of you would be fine even without the girls, so you waved them off and continued upwards into the mist, eager to reconnect with the other half of your group and get settled with Naoya in the tent for the night. 

—

Sukuna had found a pretty good camping spot. He was pretty sure it was in a similar position to where he’d set up on his solo winter ascent a couple of years before - a location that should be downright comfy in the mild spring weather. 

Assuming that weather stayed mild. 

It was hard to tell through all the fog, but he was almost sure he could see dark clouds rolling high in the sky. He hoped he was wrong. There hadn’t been a storm on the forecast, and if one was to roll in that could make for a very harrowing evening, especially for people like you who’d had little experience of the mountains. 

He hoped one bad night wouldn’t be enough to put you off entirely. 

“Yuki just radioed.” Satoru called out to him. “She, Shoko and Utahime are all going back down. The others are still coming I think.” 

Sukuna hummed in affirmation as he moved to set up his tent. He wished it could’ve just been you coming up, rather than you and your shithead boyfriend, but he supposed he’d rather you have a buddy in the mountains than be out there alone. If he’d had things his way, he would’ve hung back with you for the whole duration of the hike, but he didn’t need people casting suspicions on his actions. 

He’d already received some strange looks over his eagerness to teach you - the last thing he needed was the rumor mill in full operation. 

Even if the rumor mill was right in this case. 

He liked you. He really liked you. 

Feelings that he needed to keep to himself, because your boyfriend was one jealous asshole, and he was almost confident that any sign of flirting on Sukuna’s part would have Naoya taking out his anger and jealousy on you, which was the last thing he wanted. He wasn’t sure what you saw in that guy, but god, Sukuna wanted to bash his teeth in. 

He’d been watching it for months now - the depressing life you lived in which you’d excitedly bound over to Naoya to show him something you’d learned only for him to react with total disregard. Sukuna had watched the light in your eyes flicker and die each time, doing his best to control the rage boiling in his chest. 

You deserved better than that fucker. 

But he got the sense that you weren’t able to see that. 

Almost everyone had set up their tents, laughing and joking and tearing into provisions by the time Naoya appeared from the mist. A couple of hours had passed since the group first found the camping spot, and Satoru welcomed him enthusiastically as he stepped into the clearing. He looked surprisingly exhausted for a man who was supposed to be experienced. 

Sukuna’s red eyes scanned the fog, waiting for you to appear behind the man. His chest squeezed when only silence followed, no sign of your presence in the mist. 

“Is it only you?” Satoru asked, voicing the very question that was on the tip of Sukuna’s tongue. 

“Yeah, the girls went down,” Naoya responded nonchalantly, shrugging off his backpack. “Is there a good place for me to set up?” Satoru’s lips parted, as if to question the man’s statement, considering Yuki had relayed specific names, but he clearly thought better of it, nodding and pointing Naoya in the direction of a clear patch of dirt for him to pitch his tent. 

Sukuna wasn’t so happy to shrug it off. 

“Yuki only said she was going down with Utahime and Shoko,” he called out to Naoya. The man turned to look at him, irritation shining in his amber eyes. Sukuna was well aware that Naoya despised him just as much as he despised Naoya. 

“They all went. Think I don’t know where my own girlfriend is?” Naoya snapped. 

Sukuna stared him down for a moment before leaving him be, heading over to Satoru and asking for the radio. Speaking into it, he called out for Yuki, praying that they were still within a reasonable range to pick up his voice. 

He was met with only silence, cursing under his breath at the realisation that they were probably all the way back in the valley by that point and likely impossible to reach. His crimson gaze fell to Naoya once more, watching him hum as he set up his tent without a care in the world. 

Something in the pit of Sukuna’s stomach told him that there was something wrong. You hadn’t gone back with Yuki. You’d been so happy all day, so excited about your first major peak. Not only that, but you’d been in good condition - he’d been watching you whenever he could, he’d been proud at how well you were doing. 

You wouldn’t have turned back. And if you had, Yuki would’ve listed your name when she was heading down. Yuki was no newcomer to the mountains - she was responsible and experienced and she always emphasised the importance of good communications. And if you’d have turned back any later, Naoya should’ve gone with you - it's what any sensible person would’ve done. 

But he was here, and you weren’t. And you hadn’t gone with Yuki. So you were alone. 

Sukuna’s first instinct was to bash Naoya’s head in. He wanted to walk over there and silence that bastard’s humming with a well placed rock to the head. What kind of a man - an experienced mountaineer, no less - would abandon their inexperienced girlfriend on the side of a mountain? 

It wasn’t like Sukuna doubted your ability. He’d taught you all you needed to know, but putting those things into practice alone, at altitude, and in adverse weather was a whole other thing. 

Instead of doing anything about Naoya, he parked that issue temporarily and quickly moved to dismantle his own tent. He wasn’t going to sit there and do nothing while your location was unaccounted for. Even if you had gone down shortly after Yuki, even if you’d made it back to the valley by yourself, he wasn’t going to roll the dice on your life. 

He’d go back the way they’d come and he’d walk until he found you - even if that happened to be safe and sound at the bottom of the mountain. 

“What’re you doing?” Satoru asked, hovering as Sukuna put his stuff back into his pack. Naoya had stopped to watch, a sneer on his already ugly face. 

“I don’t think she went down with Yuki. I need to make sure the boyfriend of the year over there didn’t leave her in some bad situation,” Sukuna explained.

“Oh my god, she’s fine.” Naoya snapped from across the campsite. “Yuki just misspoke, she went down with them. Why is it your problem anyway? It's not like she’s your girlfriend.” 

The defensive edge to the man’s voice told Sukuna all he needed to know, and he ignored the jabs in favour of packing up more quickly. He didn’t want it to get too dark - if something bad had happened and you didn’t have your headlamp on it would be impossible to find you at night. 

Unfortunately, Naoya seemed to have no interest in letting up. “I mean seriously? You’re actually doing this? I know you wanna fuck her but she’s always been a loyal little thing - she ain’t gonna put out for you because of this. I think she’s realised that she isn’t cut out for this type of shit - she went back down to safety with the rest of the girls and I think she’ll probably quit the club. She can get back to what she’s good at.” 

Sukuna’s hands stilled as he zipped his bag shut, his expression calm as he finally looked at the man before him. There was malice in his expression and a clear, guilty desire to keep Sukuna from trekking back down the mountain path. 

“‘She can get back to what she’s good at’?” Sukuna asked, drawing himself up to his full height. “And what would that be?” 

The smug grin Naoya shot him was sickening. “Making me dinner.” 

Sukuna laughed, a deep unpleasant sound rumbling from his chest. “Right.” He took a step forward, towering over your boyfriend who he deeply hoped would be your ex-boyfriend after that expedition. Before Naoya could react, Sukuna grabbed him by the front of his raincoat. “Listen. I’m going back down that path. If I find her out there, abandoned and alone, be assured that I’ll beat you so badly that you’ll never climb another mountain again. Do you understand me?” 

Fear flickered in Naoya’s amber eyes, but he pushed it down quickly, replacing it with a scowl. “Get the fuck off me.” 

Sukuna let him go, revelling in the way he stumbled about off balance, barely keeping himself from careening onto the floor. If he was being honest with himself, the desire to enact justice on Naoya in that moment was tempting, but he could wait. Every moment he spent in that camp was another moment of peril for you. 

And unlike Naoya, he wouldn’t leave you to a night alone on a mountain. 

—

You weren’t sure when you’d lost Naoya. 

He’d been picking up the pace significantly while you’d been getting slower and slower, and despite calling out for him to wait for you to catch up, eventually he just disappeared off into the fog - the sound of his footsteps fading entirely. 

It had left you at a loss, unsure as to whether you should keep going or turn back. You were certain that the summit camp probably wasn’t too far off, but you had no real idea of how far that distance might actually be, and had a vague concern that you might take a wrong turn in the ever-thickening fog, leaving you stranded for the night. You and Naoya were sharing a tent which he’d been carrying, and subsequently ending up alone for the evening wasn’t ideal for you. 

The most you’d be able to do is wrap yourself in your sleeping bag and find a sheltered place to hunker down for the night. 

But it shouldn’t come to that. 

Getting down to the valley would take too long, and you weren’t sure where Yuki and the gang would’ve settled anyway. Naoya had the radio. He had everything really, which meant that the only thing you could do was continue upwards and hope that you stumbled across the other half of your group. 

It was a plan that was going okay until you’d carelessly stepped on a loose rock, sending you tumbling back down a hill of scree you’d spent the past half an hour climbing. 

At first you’d thought only your morale was damaged, your mind exhausted at the prospect of having to get back up and reascend a slope you’d already climbed once. But as you struggled to get to your feet, you realised that it wasn’t only your mind that had undergone damage.

A hot pain spread through your ankle as you tried to stand, sending you straight back down to the floor with a yelp. Panic instantly overcame you, the sudden realisation of where you were hitting you like a tonne of bricks. Naoya, your boyfriend, had abandoned you on the side of a mountain. He’d left you in the fog, beneath the setting sun, without a tent and without a radio. And now you were injured.

If you didn’t know better, you would’ve said he was actively trying to kill you. 

But what was more likely was that he was just proving the point he’d been trying to make all along - that you weren’t cut out for the life of a mountaineer. 

And considering your condition, could you really disagree with him? 

Soft sobs overtook you, and you began to spiral. You weren’t sure how long you sat there, shivering as the cold grew more intense, mumbling incoherently to yourself about how you should’ve gone back down to the valley with Yuki. 

Perhaps you never should’ve tried facing the mountains in the first place. 

Maybe Naoya was right. 

They were thoughts that fled from your mind at the blessed sight of a headlamp cutting through the fog from above, footsteps crunching evenly on scree, picking up in speed the moment the light shone upon your sorry figure huddled on the ground. 

“Fuck, are you okay?” Sukuna’s voice had a tremor of relief shooting through you, and more tears swelled at the corners of your eyes. He was crouching down in front of you, expression laden with concern as he scanned your cowering form. One of his hands reached for your face, wiping away tears carefully while he waited for you to answer him. 

“My ankle…” You mumbled. Everything was too overwhelming for you to articulate any further, your words already coming out all choked and shaky. Sukuna didn’t need to hear any more, attention instantly shifting to your foot. His hands moved to prod gently at it, watching your face for a grimace which came quickly under his touch. 

“Does that hurt?” 

You nodded. He bit down on his lip and quickly moved to untie the lace of your boot. A soft whimper left your lips as he pulled it from your foot, but he was right to pay your reaction no mind since you were overcome with relief once your ankle was freed from those rigid confines pressing down too tightly upon it. 

It had swollen up significantly in the time you’d been sitting there waiting for someone to come for you. 

“Right. I’ll deal with the ankle soon but I want to get us to someplace better first before it gets fully dark.” It was only just occurring to you that the wind had started to pick up a little, your clothes ruffled by air rushing against you. It would be best to be in a less exposed place - Sukuna had taught you that exposure made all the difference when dealing with bad weather.

“There was a plateau back down at the bottom of this slope,” you mumbled, remembering the slight respite you’d had from the seemingly neverending onslaught of uphill.

Sukuna gave you a proud smile and it made your heart flutter. “Yeah, that would work. I’m gonna carry you down there, if that’s okay? I don’t think you should try walking on that ankle until we give it a proper look.” 

You wanted to collapse into fresh tears at the suggestion. While your boyfriend, the person who was supposed to look after you, had abandoned you on the side of your first big mountain, Sukuna was here offering to carry you to safety. The feeling his offer was giving you had a risk of overwhelming you entirely, utterly grateful that he was the person who’d come back to look for you. 

Naively, you wondered if Naoya had sent him down to look for you. It was a weak hope, a desperate, delusional belief that your boyfriend wasn’t as cruel as he truly was. 

“Yeah, that’s okay,” you said, quietly. You tried to ignore how pleasant it felt when Sukuna crouched down to scoop you up into his arms. His touch felt warm against your body which had grown cold over the past few hours of inactivity. The arms holding you were strong and secure, building a feeling of safety knowing he was there with you. 

Naoya would’ve taken issue with it, but you wished you’d asked Sukuna to stick with you throughout the whole trip. Things would’ve felt better if it was him you were relying on rather than your boyfriend. In his lessons he’d always emphasised the importance of matching your pace with a mountain buddy - always checking that they weren’t far behind. 

Rules that a supposedly experienced mountaineer like Naoya should’ve been well aware of. 

Sukuna strode down the rest of the hill with ease, keeping you tucked close against him in a princess carry. Considering that you had your pack still on your back you were surprised at how easy he made the whole thing look, because he wasn’t exactly carrying a light load between you in his arms and his own bag on his back. But he didn’t complain or demonstrate any signs of struggle. 

Outside of the fact that he was largely silent until you reached your destination. 

You didn’t mind that. It wasn’t like you were in the mood to talk either, your mind swimming with all kinds of things now that you were in safe hands. Naoya had left you behind to die. You could’ve died if no one had come back for you. Exposure could’ve gotten to you, or an animal, or some person with ill-intent prowling the mountainside. 

He’d left you helpless and defenceless. 

And, as rain started to drip from the sky above, you realised that if Sukuna hadn’t come for you, it would’ve been an evening out in the storm, at altitude, with nothing but your rain jacket and sleeping bag to huddle within. 

You could’ve died. 

Sukuna found a well sheltered area and placed you down while he set up the tent. You were in awe at how quickly he got it done - the same actions would’ve taken you three times the time it took his experienced hands to get it sorted. You were grateful for the speed, because it meant the two of you made it inside before the worst of the rain began to hammer down from the sky above. 

“Okay. First the ankle. Then everything else.” 

You tilted your head a little at his statement, not quite sure what he meant by everything else, but you assumed he was referring more to your mental condition and questions around how you’d ended up in your terrible position in the first place. You hoped he wouldn’t be mad at you for failing to make it up to the peak after how much time he’d spent teaching you things. 

You thought maybe he’d chastise you for things like not having your own tent or radio, but Naoya had been insistent about carrying those items for you, assuring you that he’d stick at your side and claiming his actions were out of a desire to keep your pack as light as possible. 

You were stupid to have believed him.

Sukuna knelt by your foot, removing your sock and inspecting the damage carefully. His fingers pressed delicately against the skin and you found yourself admiring his concentrated expression in the lamplight. “I don’t think it's broken,” he said. “Probably just twisted.” 

Reaching into his first aid kit, he found a bandage which he wrapped around the problem area, before pulling out an ice pack and snapping to activate its effects. He placed the pack down on your ankle, earning a little hiss from you which pulled a small smile from his otherwise serious face. 

He’d been really serious since he’d found you, his expression all irritated and stormy. 

Was he angry with you? Frustrated that he’d had to come back down the mountain to your aid? You didn’t like the idea of being his burden. 

“Endure the cold for a bit - it’ll make you feel much better.” he said, placing a warm hand on your calf. Your breath hitched involuntarily at the contact and Sukuna quickly withdrew from you, a tinge of guilt flickering across his handsome face. He instantly busied himself before you could question it, moving onto the next stage of tending to your injury.

He fumbled about in his pack and withdrew some clothing, bundling it up into a small pile and wedging it beneath your foot to elevate it a little. Nothing he was doing was particularly revolutionary - on the contrary, his actions were all things he’d taught you to do in the event of an injury. 

You’d just been too panicked to do anything on that scree slope. 

Perhaps he was mad at you for that too. 

Sukuna laid out his sleeping mat next to you, his nose wrinkling at the revelation that you didn’t have one because it was in Naoya’s possession. He slid his mat beneath you, keen not to have you lying on the floor, before pulling out his sleeping bag and sitting on top of that for some amount of comfort. 

“So, what happened?” Sukuna asked. His voice was a little clipped, as if he was holding himself back from saying what he really wanted to say. 

“I was rushing and lost my footing on some scree-”

“No. I mean, why are you alone?” 

“Oh.” You shrugged, taking a deep breath and avoiding his eyes. There was a sticky feeling building up in your throat, keeping your words down. If you said the truth aloud you were certain you’d burst into tears again. “I don’t know,” you mumbled finally. 

“You don’t know?” He echoed. 

“It just sort of happened. The girls went back down the mountain and Naoya kept going quicker and then we got separated somewhere in the fog. I imagine he was probably waiting somewhere up ahead for me but then I slipped.” You weren’t sure why you were trying to defend your boyfriend. You weren’t naive enough to truly believe he’d been waiting up ahead for you. 

He’d left you. 

But the idea of airing out just how stupid you were to be in that relationship in the first place felt humiliating. You wanted to at least pretend that Naoya didn’t leave you for dead - that you weren’t the fool who had stayed for years with an abusive boyfriend when you should’ve just left. 

You didn’t want Sukuna to think you were completely pathetic. 

“Naoya arrived at the camp hours ago,” Sukuna said, his tone detached, as if he wanted to avoid projecting any of his own emotion onto you. “He said you’d gone back down with the rest of the girls.” 

The horrified expression on your face must’ve said it all, because Sukuna’s impartiality quickly faded, rage burning within those crimson eyes. Naoya really had abandoned you. And not only that, he’d also attempted to sabotage any retrieval attempt that might be made for you. He’d outright claimed you were safe when he knew no such thing. 

It was a thought that made you sick, and once again the tears started to flow, dripping down your cheeks. You’d spent years with that man, feeling like you were less than good enough. You’d let him break you down, put up with his endless bullying and tormenting, all because he’d been sweet to you at the start. 

You’d always thought you weren’t good enough, always thought that it was your fault he was so unpleasant with you. 

Now it felt like your eyes were open for the first time. 

He’d left you on the side of a mountain. He couldn’t care less about your wellbeing. He couldn’t care less about you unless you were making him dinner. 

And you’d put up with it. 

You were a fool. 

“I knew that fucker was lying,” Sukuna hissed. “Yuki didn’t say your name when she radioed in to say she was heading back. She’s always good with that sort of thing. Fuck, I’m glad I came down to check, who knows what would’ve happened if-” 

He cut himself off, faltering before he could finish the sentence. It was clear that he didn’t want to scare or upset you further, not when you’d already reduced yourself to a puddle of tears. You didn’t want to imagine what fate the night would’ve brought if not for Sukuna arriving as your saviour. 

Falling silent, he shuffled a little closer to you. Reaching out delicately he began to wipe away your tears with his thumb. The touch of his skin against yours felt pleasant, and you found your sobs faltering at the new found comfort he was providing. A deeply loyal part of you urged you to pull away, reminding you of your boyfriend. You immediately pushed the thought aside. 

Naoya wasn’t your boyfriend. 

Not after what he’d done. 

“Don’t cry. You’re okay. I found you and we’ll make it through the night together. I’m not going anywhere.” Sukuna’s words were soothing, and you found yourself nodding between sniffles, your tears gradually drying up. You hadn’t realised you were shivering until Sukuna tentatively wrapped an arm around you, pulling you up and close to him. 

The storm had worsened outside, and you huddled down in your jacket, letting yourself lean into Sukuna’s chest to keep the shivering at bay. If this was how you felt inside a tent with another human to warm you, you hated to think how you would’ve felt still stuck all alone on the scree. 

It didn’t bear considering. 

“You should report that asshole to the police once we get down. Nothing will come of it because it's hard to prove intent, but this was an active attempt on your life. He had a duty of care he ignored, stripped you of shelter and then tried to prevent a rescue. I have half a mind to kill him myself.” Sukuna’s voice rumbled through his body. 

No one had ever really stood up for you before. Naoya was always good at being charming when it mattered. Your parents and the rest of your family had always seen him as a good prospect - a polite and handsome man from a well off family. With your friends, you’d done the damage on your own, always defending him, manipulated by him to act like the perfect picture of an abused girlfriend. 

“I’m so stupid,” you whispered. 

“What?” Sukuna asked, pulling back ever so slightly so he could look at you properly. You hadn’t spoken at all since the reveal, and your quiet words clearly caught him off guard. 

“I’ve wasted so much of my life with him. Spent so much time defending him like he was some good guy. I only joined this club to impress him and all he ever did was tell me how useless I was at stuff like this - at everything. Did you know that he spent most of this hike staring at Yuki’s ass? And yet, when I’d tell him about how much stuff you’d taught me he’d get all mad about me talking to another guy and verbally berate me until I cried. And I just let it all happen. You must think I’m an idiot.” 

Sukuna hesitated, searching for the right words. It made you smile in a twisted sort of way, because he was definitely trying to find something to say that wouldn’t indirectly call you stupid - an impossibility considering the circumstances. Now that your eyes were open you could finally see how foolish you’d been. 

You just wanted to go home. Forget mountaineering or anything else you’d tried in an attempt to bond with that asshole.

“I don’t think you’re an idiot,” he said finally. “I think guys like that are very good at getting their way, and you happened to be his victim.” The words were uncannily gentle, and at a glance at Sukuna’s face you could tell he was out of his comfort zone, but trying his best. He tightened his grip on you as a sudden gust of wind battered the tent. 

The touch had your heart fluttering, and you wondered how Sukuna felt about your current position. It was probably just a necessity in his eyes - a bid to warm up a tired and stressed woman, nothing more than that. 

With your loyalty to Naoya stranded somewhere on the mountain never to be recovered, you found yourself wishing the contact was something more than that. 

But considering your woefully pathetic attempt at summiting this relatively easy peak, you doubted Sukuna held you in high regard at all. His type was probably some strong, confident girl who already knew all her outdoor skills without Sukuna’s input. The type of woman he could rely on to partner with for dangerous and difficult peaks. 

That wasn’t you. 

You weren’t sure you’d step foot on a mountain again after this. 

“Maybe you don’t think I’m an idiot for that, but you probably think I am for all this.” You gestured in the general direction of your foot, still humiliated at the thought of Sukuna having to rush down the mountain to your rescue, like you couldn’t be left unsupervised for a single moment without finding yourself in need of rescue. 

Much to your chagrin, Sukuna laughed. “An idiot for getting injured? No, that’s practically a rite of passage. You were doing great through most of the hike - I was keeping an eye on you before the group split in half. We’ll get you down the mountain and get your ankle sorted, and then you can try this peak again another time.” 

Sukuna’s optimism had butterflies swarming in your stomach, but years of insults and abuse weren’t so easily displaced. You lowered your gaze, staring down at your hands in your lap. “I don’t know. I just wonder if Naoya was right. Maybe I’m not cut out for this.” 

Sukuna pulled a face, clearly displeased by that statement. 

“Do you like being in the mountains?” He asked simply. 

He made no statement on your skill, no attack on anything your boyfriend had told you. Asked nothing more than whether you liked being out in the fresh air, doing what you’d been doing before your ankle had been injured. 

And you did. 

You really did like it. 

“Yeah. I do.” 

“Then you are cut out for this. Enjoyment is literally the only requirement,” he said earnestly. “Besides, that guy’s full of shit. I taught you everything you needed to know and I have faith in your abilities. If you need to listen to someone else’s opinion to determine your value, how about you consider mine instead of his.” 

A flush appeared across your cheeks. Those were the kind of compliments Sukuna would always pay you. Nothing particularly special or flowery, but deeply genuine in a way that had your whole body bursting with pride, pushing the rot of Naoya’s insults from your veins and replacing it with Sukuna’s approval. 

“We’ll come back here together in a few weeks, just the two of us, and we’ll do this peak. I can promise you it’ll be better. I won’t abandon you in the fog.” You believed him, nodding a little in agreement. Even in your fragile mental state that evening, you couldn’t help the excited flip of your stomach at the thought of Sukuna wanting to do something alone with you. 

The mountaineering club had been a means for you to learn your skills to climb alone with Naoya. You hadn’t expected that it would leave you excited at the prospect of climbing with another man. 

Still, you tried not to get ahead of yourself. Your little crush on Sukuna, which had been present for several months more than you were really willing to admit, seemed to have finally found the freedom to really take over your thoughts. Your heart was practically in your throat at your current proximity to him, a desire coursing through your whole body. 

You needed to push it back down even with Naoya out of the picture, because you were certain Sukuna was just being friendly, just being a better person than Naoya was. You couldn’t afford to let your mind run wild with fantasies. 

At least, that’s what you’d told yourself. 

The two of you had sat in silence for a while after Sukuna’s offer of climbing alone together, still huddled together and listening to the wind and rain outside the tent. You found yourself calmed by the steady rhythm of Sukuna’s heartbeat, basking in the warmth of his body which took your mind off the cold compress burning at your ankle. 

“Do you mind if we share the sleeping mat? It's okay if not, but it would be warmer for you and more comfy for me that way.” Considering that the two of you had been cuddling for a while, you didn’t see the issue. Anything was fine in matters of survival and you were more than happy to remain close to Sukuna. 

“Yeah, sure. We can zip our sleeping bags together.” 

Sukuna’s lashes fluttered and you swore you could see a dusting of pink on his cheeks, but you were quick to disregard it. It had been a long and exhausting day, and you were likely just seeing what you wanted to see. 

The cold compress had started to lose its effect, and Sukuna removed it from your ankle while the two of you shuffled about to get ready for bed. Your ankle was feeling much better after a period of rest and elevation, and you found you could move it again without excruciating pain. Getting back down the mountain might still be an issue, but it was one you could leave to figure out in the morning. 

Zipping your sleeping bags together and settling down on the sleeping mat, Sukuna made space for you beside him. You had to half lay on him for you both to stay on the padding, but with how warm his body seemed to run, you really didn’t mind. He wrapped his arm around you, nestling you close against him under the guise of conserving space - an action that had your whole body thrumming with electricity. 

You couldn’t remember the last time you’d felt that way. For months, maybe even years, the only thing you’d felt under Naoya’s touch was mild dread. This was something nicer, something more exciting - a feeling you wanted to experience over and over again. 

“Warm enough?” Sukuna asked, giving you a reassuring squeeze. The tent was relatively cool, the fabric being battered by the storm outside, all of which seemed distant as you lay there in Sukuna’s grip. It was a safe and warm place to be, one where you could take your mind off troubles and anxieties knowing he was there to keep anything and everything at bay. 

Troubles which Naoya had actively brought upon your life, were effectively chased away by Sukuna. 

How you wished you’d met the pink-haired man earlier in your life. 

“Warm enough,” you echoed, your voice coming out muffled as you buried your face into his chest. 

Again, the two of you fell into comfortable silence, listening to the whistling of wind and basking in the feeling of your bodies pressed close together. You were half asleep and almost convinced that Sukuna was already asleep, when his deep voice cut through the darkness and silence. 

“I don’t usually go on these things, you know,” he confessed quietly. “This is my first one. I’m only in the club because it gives you connections for exhibition funding and learning new skills. Usually I do mountains solo and usually I do stuff much harder than this.” He waved his hand in the direction of the tent’s exit. 

A guilt blossomed in your gut at the speech, recalling similar words from your boyfriend when you’d brought up the trip. He’d said that climbs in the Japanese Alps outside of wintertime were nothing special, and that the whole thing would likely be so easy that he could do it in his sleep. He’d only agreed to go after you’d begged him, reminding him that you didn’t have the experience he did. 

“I’m only here because of you,” Sukuna continued. The guilt within you only grew sharper. Was Sukuna trying to imply that he was only present out of concern for your inexperience? Had you forced him along because he knew something like this would happen? Had he known he’d need to come to your rescue?

“Sorry. I must be such a burden,” you mumbled quietly, burying your face in your sleeping bag. 

Did Sukuna really want to commit to climbing alone with you knowing that you were so much less experienced than he was? Or was he just doing it because he felt bad for you? You were likely a pitiful sight with your messed up ankle and an abusive boyfriend who had abandoned you. 

Sukuna blinked rapidly, astute enough to swiftly connect the dots. “What? No, that’s not- I was trying to say something nice. I was saying I only came along because I enjoy spending time with you. I don’t like these group things and I prefer to do harder stuff but I’m here because you’re here, and I like you.” 

Your heart was pounding so hard you could hear it in your ears, completely drowning out the sound of any thoughts on how you were supposed to reply to that. You were too caught up on the word ‘like’, on the way Sukuna shifted ever so slightly against you, pulling you more firmly against his body. 

“What?” You asked, dumbly. 

“I like you,” he repeated. “I think you’re so cute and I love how happy you get whenever you learn something new and I’m so fucking exhausted of watching your boyfriend ignore you and take you for granted when I’d cherish you.” 

Again, your stomach flipped, your ears growing warm. 

“And when that fucker showed up at the top of the mountain without you, I wanted to kill him. When I found you all cold and alone on the slope I just- fuck. I want to keep you safe. I want to be the person who looks out for you, I want to take care of you in a way that guy seems unwilling to. He has no idea what he has- had, while I understand exactly what you’re worth. I want to take you to the mountains at my side because unlike him, I’d be thrilled to have you as my hiking partner.” 

Before you knew what was happening, you were crying again, wetting his clothes immediately with your tears. Your shoulders were shuddering and you could feel Sukuna’s heartrate picking up. It seemed like he was starting to panic - concerned that you were upset by his words when the reality was the total opposite. 

You’d never heard something so romantic from Naoya and you never would. To have someone speak such beautiful words to you felt surreal and your body had no idea how to react beyond sobbing from being so overwhelmed with love and affection. 

“Sorry,” Sukuna said quickly. “I know it's been a long day, now probably wasn’t the time to say anything. You don’t have to respond-”

He faltered as you peered up at him, your face wet with tears. He usually looked so confident, and even then there was still some atmosphere of certainty about him, but he couldn’t fully hide the glimmer of anxiety in his lovely red eyes. There was a fear of rejection buried within him, a fate that he seemed almost certain he was going to face. 

If only he could step into your shoes for a moment and feel all the emotion rushing over you at his confession

You didn’t say anything, you couldn’t think of anything that would suffice as a response to his outpouring of desire. Instead you tilted your face upwards, lips parting softly in a clear signal - one that Sukuna caught onto immediately. He closed the gap swiftly, lips slotting perfectly against yours with a warmth you’d never experienced before. 

Naoya’s kiss had always been domineering - a wet and unpleasant experience. Sukuna’s kiss was gentle and exploratory. His lips took the time to appreciate yours, to linger on that lovely shared warmth and soak in the feeling of being connected so intimately for the first time. 

His tongue ran along your lips carefully, requesting for you to open your mouth. You complied easily, letting him hold you ever closer as his tongue pressed into yours, deepening the kiss in a way that felt so natural despite the fact that you’d never kissed each other before. 

A rumble of thunder overhead had the two of you parting for a second, and you found your shivering renewed as a particularly cold wind blew through the tent. Sukuna’s red eyes went to the entryway, the space illuminating for a second as another flash of lightning ripped through the sky above. His hands rubbed your back soothingly at a louder rumble overhead. 

“I’m so glad I came down to find you,” he whispered. 

“Thank you for coming to find me,” you mumbled, eyes fixed on his handsome face, your mind still struggling to catch up to all that had transpired in the past few minutes. Thoughts of Naoya and all the suffering he’d put you through seemed distant in the intimacy of that tent. “I feel so lucky. Injured ankle aside.” You giggled softly, heart jumping at the way Sukuna grinned back at you, pressing another soft kiss to your lips. 

There was a gratefulness to his expression, a soft affection in his gaze which made you feel seen and special in a way you’d never felt with Naoya. It had you sinking deep into another kiss, your lips locked against his in a deeply intoxicating manner. All the stress and the anxiety of the day seemed to wash away beneath his grip. 

Even with the storm raging outside, you felt safe and warm with him there beside you.

You should’ve known about his feelings for you - should’ve understood the moment Yuki had made a comment about how Sukuna never usually spoke to anyone. He’d spent so much time on you, being so gentle in his teachings, making sure you knew what you were doing, making sure you were praised. 

He’d liked you from the start and you’d been too blind to see it. 

Too beaten down by your own experiences in relationships to believe that any affection directed towards you would be legitimate. 

You wished you could’ve puzzled it out sooner. You wished you could’ve noticed the soft look that always sparkled in Sukuna’s eyes whenever he looked at you. You wished you’d dumped Naoya several years ago, because it shouldn’t have taken an abandonment on the side of the mountain for you to realise how truly awful your ex-boyfriend was. 

But what was done was done. Sukuna’s hands were on you now, and that was all that mattered. You’d made it in the end, even if it had taken you a little longer to get there than you would’ve ideally liked. 

“You’re so pretty,” he whispered as the two of you broke apart for breath, red eyes scanning your face like he was committing your features to memory. “How Naoya could be so stupid, I have no idea.” 

“He’s not a smart man.” 

“No. He really isn’t.” Sukuna agreed. “But his loss is my gain.” 

You hummed, leaning against Sukuna’s chest once more, listening to his heartbeat beneath you. Despite the excitement, you were suddenly aware of how tired you were, and how much the cold was still seeping in through your clothes and down into your bones. Altitude was no joke, and the pleasant spring warmth was nowhere to be found on the mountainside that evening. 

“Are you still cold? You’re shivering.” It wasn’t possible for Sukuna to physically pull you closer to him than you already were, but he gave it an attempt all the same, practically crushing you in his grip. 

“A little, yeah.” 

“Shit. Once sec.” Moving away from you for a moment, he reached out of the sleeping bag and rummaged about in his bag, withdrawing his down jacket and draping it around your shoulders like an additional blanket. You were grateful for the added warmth, coccooned in between that and Sukuna’s warm body. 

For a few moments you lay there, your shivering finally subsiding, only for all the hairs on your neck to raise at the feeling of Sukuna’s voice vibrating against the top of your head. “There is another way I could keep you warm.” 

His tone was suggestive and perhaps a little amused. The comment had heat billowing throughout your body, your gut tightening at the suggestion of something you’d never allowed yourself to think of before. Sukuna was very attractive, and sometimes your mind had drifted in his direction when your hand had been caught between your thighs. But you’d always scolded yourself for it, had always driven away the idea of picturing a man you actually knew when you had a boyfriend. 

Now the suggestion was right there on the table as something real and tangible, and your mind was conjuring all sorts of exciting imagery. 

“O-oh. Yeah, that could be nice,” you said with a sudden rush of confidence. It was Sukuna’s turn to falter, red eyes suddenly wide with surprise, as if you’d called some bluff without even realising it. 

“I don’t have a condom,” he murmured, pushing you back ever so slightly so he could look properly at your face. “Sorry, I wasn’t actually expecting…this.” 

“I am on the pill,” you offered a little bashfully, embarrassed to have reacted so enthusiastically to what you were now realising was a joke. “But we can wait if you’d rather use a-” 

“No, no-,” his face was definitely a little red this time, seemingly caught off by your willingness. “If you want to, I’d like to. I just…” He rubbed his neck a little awkwardly. “I was just teasing and you surprised me, I guess. You’re always surprising me.” 

Before you could backtrack or come up with some witty response, Sukuna recovered himself and his lips were on your neck. You let out a soft whimper at the sensation of his teeth dragging against your sensitive skin, his lips latching onto you and sucking purple marks onto you with no concern for who might see them the next day. 

As far as he was concerned you were his. Naoya could rage all he wanted. If he wanted to keep his girlfriend he shouldn’t have discarded her on the mountainside. Bitterly, you hoped Naoya found out exactly what you and Sukuna had done that night. Let him seethe. Let him reflect on all that he’d lost. 

The bastard deserved all that misery and more. 

Sukuna’s hands found their way beneath your clothes, calloused fingers pressing against your skin with care. You hadn’t realised how much your whole body was aching until he was touching you like that, your muscles flexing at the new contact. 

You took his actions as a sign to do the same, sliding your own fingers beneath his shirt and pressing them against his abs. You knew he was well built - on hotter days he’d been shirtless when working on teaching you to lead climb, and you’d pretty shamelessly stared at him until your mind had reminded you of your boyfriend.

It would be nice for him to be shirtless now, but neither of you felt like removing any layers of clothing in the cold, so for the time being your touch would have to suffice. That was a freedom that Sukuna seemed to be taking full advantage of, mapping out your body with his hands, his fingers moving to your breasts and squeezing, red eyes lighting up at the little moan it earned him. 

“Really shouldn’t be doing this now,” he whispered huskily against your ear. “Had the whole thing planned out. Figured once you’d broken up with Naoya that I’d take you out on a nice date and then bring you back to my place so we could do this properly. But here we are.” 

You giggled softly at the dismay in his tone. “We can still stop.” 

“No. I want this now. You aren’t so easily resisted. But mark my words, once we’re back home, I’m going to take my time with you. I want to look at you properly beyond just fumbling about in a dark tent - as hot as this is.” 

Giggling again, you nodded, in total agreement with his sentiment. Doing things like this, while a little limited, did feel exciting in its own way. It felt like you were keeping some secret with each other, doing whatever you could in the dark without anyone else knowing about it. There was an allure to it that you couldn’t quite put your finger on. 

With Sukuna’s attention on your breasts, you were the one that ended up making a major move first. Your hand slid down beneath the waistband of his trousers, finding its way into his briefs. He let out a groan at the feeling of your hand brushing against his cock, which twitched erratically at the slightest touch. 

It felt big beneath your fingers, and you hadn’t realised that your breath had hitched until Sukuna was letting out a chuckle. 

“Impressed?” 

“Maybe,” you mumbled shyly. You didn’t have much of a point of reference for such things. Naoya was the only man you’d ever been with, and you imagined that he wasn’t packing anything particularly unique down there. Not if Sukuna’s size was anything to go by. You wrapped your fingers around the shaft, enjoying the way Sukuna shivered in pleasure. 

Meanwhile, Sukuna mirrored your actions, his fingers moving down your body until they were grazing against your panties. It was a little embarrassing how damp the fabric had grown, your pussy desperately slick from the events of the evening. Your body wanted Sukuna just as much as your heart and mind did, and it was making that fact glaringly obvious. 

“So wet,” he said with a chuckle. “There I was all nervous that you wouldn’t feel the same. Shows what I know, huh?” 

You flushed, glancing away from him in embarrassment as his fingers pushed your panties to the side, giving him free access to your pussy beneath. His fingers moved deftly through your folds, moving the slick around before rubbing at your clit, leaving you whining his name and squeezing his cock a little tighter. 

“Cute,” he hummed, his nose brushing against yours. One of his fingers prodded at your opening, pushing in with a little effort. He took a few minutes opening you up with two of his fingers, languidly stuffing you full with them to prepare you. You didn’t want to admit to how emotional the whole thing made you feel, because Naoya had always said that foreplay was a myth. 

Never before had you been prepared for anything, and Sukuna taking so much time to do so had your heart fluttering. 

You tried your best to return the favour, stroking his cock as best as you could while it was still confined beneath his clothes, but he didn’t seem to pay that too much attention - completely fixed on making you cum around his fingers before moving onto anything else. That was another thing that Naoya had never done. Cumming with him was so infrequent that you’d almost grown certain that you couldn’t do it with another person. 

And yet, Sukuna had you doing it in a matter of minutes - your toes curling in desperate pleasure as you gushed over his fingers with a sweet little gasp. 

There was no time for you to catch your breath before he was pushing your trousers and panties down ever so slightly to give him access whilst still keeping you dressed and warm. He did the same for his own clothes, gently displacing your hand from his cock and repositioning the two of you so that he was on top. 

The sleeping bag was still wrapped snugly around the two of you, keeping the warmth in effectively while he lined himself up over you, his muscular body keeping you pinned down beneath him in a position you’d be more than happy to remain in for the rest of your days. It was so nice to be under him like that, to be so surrounded by his body and heat and scent. 

It was where you were supposed to be. In some uncomfortable tent on the side of the mountain feeling happier than ever because he was there with you. 

You’d gone to the mountaineering club for Naoya, but you couldn’t help but think fate had guided your actions and really led you there for Sukuna. 

“All good?” He asked, hot breath brushing against your ear. The tip of his cock was pressed up against your opening, and you realised that he was giving you a chance to back out - showing you a level of consideration that Naoya never would. 

“Yeah,” you breathed, lashes fluttering as you peered up into lovely red eyes, letting out a whine when he finally pushed into you.

You hadn’t been prepared for just how big he was, your eyes practically rolling to the back of your skull as he pressed his way into your tight pussy. Your nails dug into his arms and a whimper left you at the intensity of the feeling. You felt like you were aware of every ridge and vein on his cock, your pussy squeezing around him each time he’d involuntarily twitch within you. 

It didn’t take long for the uncomfortable fullness to give way to pleasure once he bottomed out inside you. It had a pleasantly warm buzz running through your body once he started to thrust within you, the weight of his body keeping you still and secure, keeping you warm even as the storm picked up outside. 

Any fears of the thunder and lightning were pushed aside in favour of focusing on the feeling of being split in two. Sukuna’s lips found your neck once more, overstimulating you as he bit and sucked on the juncture between your neck and shoulder, bringing tears to your eyes beneath all the pleasure he was giving you. 

Even through the stretch it felt right to have him inside you, and it was downright heavenly each time one of his long strokes hit that one specific spot inside you, bringing stars and light to your vision each time. 

This was where you were meant to be. 

Neither of you lasted particularly long. Not after the day you’d just had, and certainly not after months of mutual crushing. You’d cum first - your body already sensitive from the previous orgasm and totally overwhelmed by the intimacy of it all. Sukuna had reached down to play with your clit while he fucked you, and that set you on a high unlike any other. 

If Naoya had known where the clit was, he’d certainly never touched it. 

And yet, there Sukuna was utilising it. You could count on one hand the number of times you’d cum from penetrative sex, but Sukuna had pulled an orgasm from you like it was easy. 

And maybe it was easy. 

Maybe Naoya just fucking sucked. 

Sukuna wasn’t far behind you in reaching his release. When you’d cum you’d clamped down around him tightly, locked in a spiral of pure pleasure unlike that which you’d experienced before. It felt better than anything you could achieve with your own hands - infinitely more intimate and lovely. 

The way you’d squeezed him so tight had sent Sukuna over the edge, prompting him to groan your name in that low tone of his as he filled you with his seed, riding out his own release to the point where you were growing overstimulated and begging him for mercy. 

Mercy which he gave you with a gentle smile and a kiss planted atop your sweaty forehead. 

The two of you lay then in the darkness, soft pants drowned beneath the howling of wind. Sukuna was holding you tightly, keeping you secure in his grip like you might vanish if he didn’t cling to you with all his might. He was still inside you, softening but present in a way that felt blissfully intimate. Whenever you’d laid with Naoya, you couldn’t wait to escape his grip and get cleaned up. 

With Sukuna, it was different. 

You could stay there with him sheathed inside you for hours - connected in a way that just felt right. 

His lips were ghosting against your hair, soothing you with kisses, running his hands over you repetitively in a bid to ensure you stayed warm at his side. Your ankle was throbbing a little from all the movement, but with Sukuna’s legs intertwined with yours you found yourself able to ignore it. All thoughts and discomforts overridden by how happy you felt in that moment. 

“Try and get some sleep,” he murmured against your hair. “I’ll look after you.” 

“I know,” you whispered. 

He smiled softly. “Just making sure you know it. Apparently you can’t take for granted that everyone will look out for you.” His tone came out a little bitter, but instead of feeling anger at the reminder of Naoya’s actions, you felt a warmth blossom across your chest at Sukuna’s display of care. 

You liked that he was angry about it. It was nice to have someone care about you for once. 

In hindsight, it was a blessing that you never made it out into the mountains alone with Naoya like you’d intended to at the start of your mountaineering training. If you had, perhaps you would’ve ended up left for dead - freezing on the side of the mountain while Naoya summoned some crocodile tears and dismissed your fate altogether. 

You were lucky to have Sukuna. Lucky to be able to continue going into the mountains with someone who actually wanted you there. Someone who would really take care of you. 

“I’m glad you’re here to look after me.” Your hand reached for his face, tracing his tattoos with great care. As pleasant as your evening with him had been, you were looking forward to making it down the mountain - to spending time with him outside of that tent. It would be nice to see just where those tattoos disappeared off to beneath his clothes. 

But that would have to wait. 

You knew that the next day would be long. An arduous trek back down the mountain was ahead of you, along with a no doubt vicious confrontation with your ex. One that you were sure Sukuna would take the lead on, but still not something you were looking forward to experiencing. 

Either way, you wouldn’t dwell on it that evening. 

Because for the time being, there was nothing you needed to worry about. The storm could rage on outside for as long as it needed to. You were safe in your tent, in the arms of a man who would never leave you alone on the side of a mountain. 

And it was possibly the happiest you’d been in a very long time. 

a/n: after getting down to the bottom of the mountain the next day I promise reader slapped naoya and sukuna beat the hell out of him :)
