Work Text:
Your hours at the base was spent largely wasting time between the few moments you got to spend with your partner. Given his skill set Iso was normally busy and had a difficult time saying no to his new friends antics which meant you saw him sparingly here and there. No one even knew the two of you were a thing, both of you not really seeing the need to announce it and not enjoying public displays of affection enough for someone to assume. Despite the lack of quality time neither of you were really bothered by it. If either of you craved affection you'd always seek the other out or find a way to communicate it and if the other was agreeable towards it then you'd meet up and have a cuddle session. Most of the time Iso also wasn't really up for a lot of heavy touching anyways so quality time was usually sitting in his or your room while doing separate things or playing a game together. Rarely, very rarely, you got texts like the one you did today containing a single emoji that barely ever saw the light of day.
A single polar bear emoji had been all you received while working on something online. You sent back a question mark, checking to see if this was truly what he was requesting or if it had been an accident. Iso in turn sent back another, confirming with you what you had assumed. Another quirk of your relationship was the fact you two had sex rarely if ever. Iso wasn't really big into sex, it being entirely gone from his mind most of the time though he wasn't outright opposed to it and made it very clear he didn't date you because of that. You yourself didn't really care. It was just sex. There were other things you could do that was just as good, if not better, that expressed your appreciation for each other as well as served as couple time. At first this little bridge seemed to make or break your relationship and was one of the last hurdles you had to get over before Iso fully relaxed around you. He was used to people making jokes or asking questions and even admitted several people broke up with him due to seemingly being offended by his lack of sexual interest in them. When it came up he said he understood them, sex was important for more people than it wasn't and he was the minority, and also understood if you didn't want to progress the relationship further. You didn't see a real problem with it and told him as much which basically opened the flood gates, making Iso almost immediately switch from awkward and standoffish to a lot more open as well as up for physical contact since it didn't come with any weight other than affection. You also discovered he wasn't as repulsed as you thought and was down to at least help you get off or let you get him off so he could move about his day if he wasn't experiencing any sensory issues. Even still you very rarely engaged in anything besides cuddling in your underwear. Sending the emoji was his way of alerting you he would like to engage in such activities, each one having a different meaning ranging from "I want to game" to "Im horny and don't want to be fix it pls" . Iso wasn't great with words but he was good with emojis so this system was incredibly effective with that little polar bear beckoning you to him.
Putting some spare clothes, snacks, and baby wipes into a bag you hauled yourself to his room. Iso had his own things he preferred for protection and added stimulation while your job was mainly clean up since he was far more bothered with bodily fluids than you were so as such you had your own little kit for these events. This wasn't to say he didn't preform any after care, you just preformed the immediate clean up since bodily fluids quickly icked him on most days. If there was even a cold or thick drop of anything he was standing across the room waiting patiently for you to clean it up and make the environment safe once again.
It was a bit late, late enough people were already in bed or getting ready for it, which was normal for these kinds of meetings. Both of you didn't like leaving a window to be interrupted or bothered even for more casual things, one unwanted comment often killing what ever mood you two were in. Both of you also stayed up incredibly late and had awful sleep schedules so night time was just better. Each of you had alarms for anything you had to be up for and by the time you did wake up, should you sleep over, everyone was usually doing their own thing since it was usually noon if not later. You did have some clothes over at his place once but a bit of a laundry mishap caused you to keep heavier track of what came into the room with you. Iso did accommodate you though and had gotten you your own laundry basket to make it easier as well as to let any stray garments have a place until you could collect and wash them. What did stay over in his room was chargers for any of your devices, controllers and gaming gear just for you, and even a multitude of snacks you'd specifically picked out which was a lot better than a shirt or pants. The only main downside of not having spare clothes at his place was he sometimes was very picky about you stealing his clothes even to sleep in. If the right garments weren't clean you typically would get a pair of boxers and not much else. Of course other times he was practically shoving you into his shirts and sweat pants, commenting how cuddle-able it made you.
Iso's door opened for you without you having to knock or text, your bio-metrics logged to allow you access when ever for convenience. Sat in bed playing on his phone was your partner, ear buds in, entirely oblivious to you entering. He was cute the way his face scrunched up at what ever he was playing or watching, the mask he sometimes wore being entirely absent in the safety of his room. Dropping your bag down seemed to pull him out of his bubble, him almost immediately dropping his phone to his chest and holding his arms out to you, making grabby hands. You of course immediately complied to his request, dropping onto his chest and letting him bury his face in your hair with a appreciative hum. It was kinda hard to believe at times that the once lethal assassin that hunted down Omen, infiltrating the protocol near flawlessly, was just a dork that liked hugs and rice balls with hoisin sauce.
"Long day?" Rubbing his hair he only responded with a muffled 'mhm' as he breathed deeply, taking in your shampoo that he always talked about enjoying. For some how much he just enjoyed your scent and textures could be considered a bit strange but it was just another way of him expressing he liked you. When your skin was unusually dry he did react to it but still insisted on touch you and nuzzling you just as much as when it was freshly lotioned. Sometimes you missed a wash day or simply forgot to condition your hair, being self concious over it being less than perfect. Even still he absolutely loved it, showing his appreciation verbally or through body language and even sometimes text if he didn't exact have the brain to touch it.
"Yoru and Jett were loud," Sitting back you freed yourself, taking your place on his lap per usual. His hands fidgeted with the flesh of your thighs, squishing them as he talked and kneading them like a cat. "Also Yoru has a crush on you, he hasn't shut up about it for the last few weeks."
"He does?!" You dramatically gasped. You weren't really surprised. Despite him claiming to be an edgy man of mystery Yoru was incredibly easy to read and had started being even more show offy around you than usual. You didn't have a real interest in him, already being taken and Iso enjoying the relationship being closed as well as Yoru being a little bit annoying."That's adorable but he is so bad at trying to pick people up, I thought he was trying to show off to Phoenix."
Iso hummed, taking out his ear buds and handing them to you so you could place them in the case on his night stand as the pressure from you sitting on him was just too good to pass up. "Jett got him to admit it, he said he was going to ask you out tomorrow when he gets back from his mission."
"So that's why you wanted to hook up? You're jealous?"
"No," it was as flat as the rest of his speech was, though the fidgeting with your thighs stopped. "I've missed you for a while and it just kind of lined up. His face is gonna be super funny when you have a bunch of hickies though so I guess it's a win?"
Nodding you had to agree. Yoru would probably go several shades of red and then try and figure out who the hell you were with or at the very least who you were fucking. All questions he had probably wouldn't get the answer to since no one knew about you and Iso and Yoru probably wouldn't just come outright and ask you if you had a partner. This may start a new base rumor, a bit of gossip the duelists could theorize about when they got bored. "Since thats settled then I assume you have plans then?"
Iso nodded before tapping your thigh, signaling for you to get up. Moving over he got up and stretched before walking over to his closet, pulling off his hoodie as he did so. He absolutely hated it getting dirty, having a meltdown the last time it got ketchup on it, so this was all just prep for later. Under his hoodie he wore nothing, probably going shirtless due to sensory seeking since the inside of the hoodie was incredibly soft and caused enough friction against his skin that he could stim by just moving his arms. This keyed you in he would be a lot more touchy than normal, and you would probably be a lot more sore than normal. Walking back over he stopped for a moment, waiting for something. Moving to a more optimal position you opened your arms for him, perhaps one of the most lethal men in the protocol crashing into them happily. His lips found yours almost immediately as you were pushed back on the bed, landing with a slight giggle as some plushie squeaked behind you probably buried under his pillow. Iso's lips were incredibly soft and precise, each kissing being purposeful and methodical despite them still being clearly hungry. It was always clear just how much he missed you or had put off asking you to come over as he didn't want to burden you and, despite dating for a while at this point, was still a bit anxious about asking for even just a goodnight kiss.
As his lips moved against yours you felt a tug on your shirt, giving a nod to him that it could be removed. The two of you parted, you tugging off your shirt while Iso sat patiently on your lap, eyes studying the flesh that once sat above your collar. He sat like that for a moment, visually strategizing what exactly he was working with while you laid with your arms spread out waiting. This happened a lot. When things such as this started the man you loved frequently had a mental list of things he was up for and may want to do. Once you were laid before him is when his brain started going over those acts and narrowing them down to a straight forward plan that you often weren't privy to. It kept things fun and also was a bit cute how he studied you and treated each action as its own task he was determined to complete well. It felt like you were a toy sometimes, but a loved one that was well valued and taken care of and not just some funko pop on a shelf.
"Do you care?" Poking the side of your neck, an inquisitive glint in his eyes you knew well. He had his sights set and a plan starting to finalize in his mind, you could practically see the gears turning and clicking into place.
"You're good, fuck me up Li" He only rolled his eyes at your theatrics before descending to your neck. It was less stimulating and more so a test, Iso first pressing him mouth against your flesh to find the easiest to grab portions as well as generally liking the feeling of your skin against his face. He had harped on before about how soft your skin was and how nice of a texture it was, especially when he was sweaty or not really vibing, often placing your hand to his mouth or rubbing his face on any exposed skin. Right now he was slow enough paced that, while a small jolt of pleasure or a tingle coursed over you here and there it was an lazy loving that was rather nice. Once he was satisfied with some more distinct marks to antagonize those who would seek to even think about dating you, his ministrations increased to be borderline ravenous. When Iso moved past theatrics he was rather passionate. It was as if the words he struggled to say were worked into your skin with every touch, each little press of his hand to your arm or nuzzle of his nose against your hair just a little bit of what he could so rarely get out. Each motion was absolutely not just a throw away one in the moment when it came to your partner. It was dedicated and thought out even down to the pressure used.
Your body also seemed to be at least one of Iso's hyper fixations. He knew every part that you liked being touched, where to press for what response, and how exactly to torment you. Even though you rarely had sex, your partner was entirely devoted to knowing anything he possibly could about how you ticked. Of course this caused its share of humor as it did pleasure such as when you got a head ache and he asked if your neck hurt, going on to explain you near always have neck tension and complain about your neck when your head hurts as if it was just common knowledge. Iso also knew what looked best on you, your sizes, and even what materials you enjoyed. A handful of times he had presented you an outfit he thought you'd look good in or enjoy only to have you bent over fucking the life out of you once you put it on. His kissing and nipping at your throat was brief but hitting every where that mattered, your breaths coming out in long sighs and occasional high notes from just a little too much stimulation on a specific spot. In the morning you would look like you lost a fight with a water color pallet or a very angry scarf, but that was the point so you couldn't complain. Seemingly pleased with his work, Iso sat back, running his eyes over you. Observation was just another part of the experience, one that had stopped making you squirm and was instead replaced with anticipation.
"Could you take your pants off?" You nodded in response, him stepping over you and standing up. Wiggling out of your pants was easy but you were oh so very aware of just how intensely he stared at you, his eyes lingering on your waist and the way it moved into your hips and then thighs, every little dip taken in. You were left entirely bare in front of him but, outside of his room being cold, felt little different than you did clothed. Iso's gaze wasn't hungry, it was analytical, he was studying you to plot his next action as if you were a video game level he was trying to beat. Sitting back down Iso dropped between your legs, bowing his head appreciatively as you parted your knees for him. Starting at your thighs he gave them a similar treatment to your throat, sighs leaving your mouth just as they had before. Just as you were falling back into the lazy rhythm a sudden sharp pain shot up from your thigh. Looking down you found Iso, a chunk of your thigh held in is mouth by his canine, the absolute goblin looking back up at you without a thought behind his eyes. "What? If you don't want to be bit like mochi don't be mochi."
Taking a fist full of his hair, you gently pulled his head back him releasing you with a pout. "Really?"
"What? I'm taking care of the after care this time, if that's alright." Tilting your head to the side you realized that Iso had a lot more in store for you than you initially thought. He only took over the entirety of the aftercare when he was about to do a number on you. Mouthing a silent 'Oh' you released him and laid back once again. Your other thigh was given a matching bite to prove an unsaid point before he returned to less sharp endeavors. Moving towards your center he wasted little time, descending upon it just as he did the rest of you. Now, despite not speaking often, Iso was incredibly good with his mouth and any activities including it were usually his favorite. As such he weirdly prided himself in his ability to give oral to the point it was near gloating though you could certainly say it was earned. His tongue trailed across you before settling on what he knew to be your most sensitive point. His tongue worked this point skillfully as if it was second nature, each lick, press, and suck being near tactical. You mewled out for him as his hands worked gentle circles into your thighs, being kind where his mouth hadn't and adding pressure to the already blossoming bruises that only increased your volume. Each sensation shifted just before you would arch, hips barely having the time to rise and meet his mouth before they settled back only to rise again a few moments later. This dance continued until you were a slightly sweaty, panting mess that had any moans only come out as whines. Finally Iso relented, giving you a moment to breath as well as stretch your overly tensed legs, you groaning as the muscles trembled.
The clink of a belt buckle alerted you that you were no longer the only one undressed, a bit too out of it to fairly care right now or oogle your partner. The mattress dipped down beside you as Iso sat and waited for you to regain yourself some. With a deep breath you sat up, getting yourself ready for what ever was next. With out warning you were lifted up effortlessly, held like you weighed nothing. You often forgot just how strong Iso was, his hoodie hiding everything and him being more precision than strength, but in this moment he carried you around as if you were made of air. A bit of disorientation and you were in is own little domain, any sounds entirely removed except for the gentle chime that normally filled the space when it wasn't used for combat. Looking at the radiant curiously you were met with a kiss on your forehead and a small laugh. This wasn't uncommon, especially when he was having an unusual pent up spike and just had to fuck you there and now, not even making it to his room, but it was still unusual.
"I don't want anyone hearing you," nodding you accepted the quick answer to your silent question, it was just a precaution to keep noises out of your business and people away from his door so you couldn't complain. The main down side of this space was it wasn't exactly soft. Iso could conjure platforms, walls, hell even a chair if he was so determined but it was all constructed of the same buzzy material. It was like a wall but with enough de-stability you could feel the rough texture of the particles with enough effort though it was only similar to something with tight sequins or a bit roughly fuzzy though it seemed to constantly ever so slightly shift. Iso seemed unbothered by it and so long as he wasn't too forceful it was fine for you. "I also wanted to try something new, watch." Closing his eyes and letting out a small hum you felt the space around you shift. The snowflake like structures moved and uncovered what was a near perfect replica of his bed, blue sheets and all. He lowered you gently, making sure his hand touched it first to ensure it was solid, before letting you sink into the mattress. It seemed authentic at first until you quickly moved your hand across the top blanket, your hand cutting through it like a cotton candy, a bit airy but still some what solid. "See, its not perfect but it should do."
"This is great," You couldn't help but smile. It took him a lot of effort to modify the space, its why he kept it so brief on the battlefield after all, so the fact he had worked so hard to accommodate you was really sweet and cute. "Im so proud of you Li, this must have taken months."
"A year. It took a year." A bashful blush covered his face and spread to the tips of his ears and shoulders. "It feels alright?"
"Yeah! Its soft! Even if I move a bunch its still really soft." Giving reassurance you flopped on your back, it feeling momentarily like a cloud before returning to a bed. You had to admit that, despite it being strange, this was nice and might be something you pestered him about when your muscles were super sore post training. Feeling like you were floating was ethereal but also relaxing.
"Good, could you turn to your stomach?" Following his order happily you laid on your stomach before being manually adjusted some, allowing him space to straddle you. The mattress around you dipped despite no pressure being placed on you, Iso entirely supporting his own weight and creating a little island as he nearly entirely surrounded you. His mouth found your neck as he sat back on his knees, massaging your body as he tenderly kissed you. Working downward a sigh of relief left your lips as he worked some knots from your back before his hands sliding up to your chin. Tilting your head back he kissed you briefly before lifting your hips up with one hand, entirely supporting you like it was nothing. He slide into you effortlessly, you letting out a long moan as he filled you. Iso wasn't incredibly big but he wasn't small either and knew expertly how to work with what he had as well as how to work with what you had, always entering and exiting perfectly. His other hand found your hair, burying itself in it for leverage which shoved your head downward, the bed giving away slightly but still supporting you and allowing you to remain comfortable unlike a normal bed would have in this moment. His grip was well enough in your hair it didn't tug much, being a gentle bit of tension with little weight on you despite the force. Your hips sunk slightly, still elevated with his fingers digging into the flesh of your hip as he settled into the position he desire.
Iso rested for a moment, your mouth hanging slightly lax as he throbbed inside you. Starting with slow, drawn out thrusts you practically drooled as he managed to make each movement matter. As his cock pulled further out of you than it had previously you gasped, it crashing into you heavily and pulling a loud shrill moan from your throat. "Just like that," He near whispered into your ear before repeating the action though quicker. Another cry left your mouth with each hit, his name slipping in as he sped up which seemed to please him as his own gasps and moans joined yours. Your flesh seemed to crave him, pulling him back just as quickly as he pulled away, every bit of your body that touched him burning as if his touch was fire. The hand in your hair slid under you to your chest, hauling you up until your back pressed into him. Loud wet slaps filled the room as he fucked you relentlessly. Teeth sunk into your neck, causing you to cry out that only morphed into a moan as the hand on your hip moved to the area he had abused earlier. Working you with his hand while his cock pounded into you, you were reaching your limit and you knew he knew. Movements became more frantic, bites more harsh, everything was seeming to climax all at once. Harshly you were dropped and then shoved face first into the mattress, a hand back in your hair, his thrusts getting greedy and forceful, each on leaving you near breathless. A curse fell out of his mouth, his hand working you to climax just as a warmth filled you. He continued to thrust out, your mind flooding with more pleasure than sense as he fucked you well past your own orgasm and into another before he finally was spent enough to stop.
His domain fell, the image of his slightly messy room filling your vision and the much welcome real pillow comforting your face. Pulling out of you mostly but not entirely, Iso moved you to be on your back before slowly re-entering you with a gasp spilling from his mouth. Settling on your chest he laid down, your hand lazily finding his hair.
"I want to stay like this for a bit." His request confused you. Usually he wanted to get things at least wiped down before any cuddling or post sex activities, absolutely hating the feeling of cold bodily fluids.
"Why?" His arms circled you and tightened, you feeling the warmth radiating off his face as he shoved it into your flesh.
"I normally don't care for cumming inside you, it's not really something I really want to do but right now..." Trailed off he adjusted himself, still being a bit hard despite the absolute railing he gave you. " Fuck, I want to fill you, just fully have you as mine and have it stay that way for as long as possible. Yoru didn't make me jealous but he did make me realize just how fast you couldn't be mine and-"
"Li Zhao Yu," Cutting him off his eyes looked up at you, peaking through his bangs that currently stuck to his head with sweat, he was adorable. Your voice was loving if a bit scolding, "It's not a competition though I won't complain about the results. I'm yours regardless and I will be for as long as I breath. Now, if you want to keep cumming inside me I don't object nor do I to the cock warming post sex, as was just demonstrated I do enjoy you fucking me and the results of it." Nodding as you spoke he kissed the center of you chest.
"Good, I was afraid that'd be strange to enjoy"
"eh," lifting himself up on his palms as you spoke, looming over you slightly while watching you speak. "A lot of people like it, it is also apart of a few kinks like breeding or messy o or control, people get really uppity about cum sometimes. It is also a possessive thing, like the chaotic neutral of a piss kink."
At this Iso snorted, "Please do not call it a chaotic neutral piss kink." His body shook with laughter, his cuteness over riding his cock twitching inside you with each burst or movement. "It won't be a constant, but it is possessive i think. Would you mind me filling you more then?"
"So you want to breed me?" You said playfully, his face twisting into one of disappointment.
"Not right now. I want you to cry my name some more while i fill you until you spill over me, we can talk about breeding later." Your joking was cut off as he nearly folded you in half, fucking you with just as much ferocity as earlier. Your voice came out strangled, his name coming out as the pleasure seemed to want to choke you, the angle seemed to at the very least muffle you given you couldn't get the air in for greater sounds. You honestly didn't know how he had this much energy but gods did he have it. Your insides did seem to be more than happy to have him, waves of pleasure being near constant as you cam again and again while he only seemed to be fueled by it. By the time tears had found the corners of your eyes, Iso finally seemed to reach the point he sought. Finally you felt another rush of warmth followed by hard thrusts and the sensation of cum running down your ass and onto the bed. Sighing Iso stopped, taking a moment before pulling out of you and sitting back.
"fuck," left his mouth shakily as he caught his breath. "Yeah, beside the mess I think I like that." Laughing weakly due to your exhaustion you just laid there, letting him get to cleaning up the room though he left you untouched, the occasional wave of cum moving out of you. A damp cloth did eventually find your sweaty face and then body. "Do you...want me to clean between your legs?"
"Nah, if it doesn't bother you then you can leave it." A look of meekness crossed his face as he left that area untouched, promising to run you the most luxurious bath he could in the morning and helping you bathe. You could only smile, letting him fuss around and fish you out something to wear so you weren't cold and didn't wake up sticker than you had to. There was a bit of excitement in you letting his cum remain in you, a red tint staying on his face as he buzzed around and occasionally cast a glance back at you. Youd have to ask him later if he found that out or enjoyed the thought of it, right now you were a bit to brainless from the wonderful fucking he was oh so kind to give you Once you were thoroughly snuggled up in his blankets, Iso had pulled on a pair of pajama pants as he dug through his snack drawer and mini fridge. Your sweet prince soon came over and presented you a bottle of apple juice and bag of chips, helping you sit up before crawling into bed beside you. He was such a cuddle bug at times, specifically now, already wrapping himself around you and plucking chips out of the bag as you fished your phone out to watch videos. As the two of you sleepily spent time together his hands found some of the spots he had abused, seemingly checking them. At one point his hand traveled downward to your now clothed crotch, curiously pressing into it which managing to pull a small soft moan from you as it was still sensitive. He apologized almost immediately, stopping once you pointed out you could still feel his cum to which he shoved his face into your neck in an effort to hide.
