Day 3: Exploring Eachother
Mershark Kirishima x Human AFAB Reader
Tumblr media
You always loved taking a walk on the beach, when suddenly, the most beautiful voice was calling to you, from beyond the waves
5.8k
(NSFW Warning)
Warning: Two dicks tbh. Mentions of abandonment. Reader not believing that Kiri is a masc mer. Oh well... seeing is believing. Fish Katsuki appears at the end.
You had always loved visiting your gran by the sea. She lived to a house right by the sea, just a bit above sea level where the water wouldn’t touch it if the oceans rose at night. She lived a bit away from the town because she believed in beings that lived under the waves, older than any human could live up to. She used to tell you of all the things she would do to help them. She would sit you by the waves, the water by your feet and warm sand under your hands and tell you stories of her advantages.
She would tell you of the handsome and beautiful mers that she was friends with and all the times they would take her under the waves to a world beyond your imagination. She told you of times where she would help provide food for them when the fisherman had overfished one too many times.
Your parents always told you to never listen to her. Your father often told you how she had swallowed one too many drops of sea water in her life. Of course, your gran knew that everyone thought she was crazy, but some of the villagers knew she wasn’t and she knew she wasn’t too. She had always hoped that one day when you were older, she could introduce you to them so that you would love them just as much as she did.
But that day never came.
With gran gone, you didn’t have anyone to visit by the coast anymore and there were not anymore visits. However, once you had learnt that your parents wanted to sell her cottage, you couldn’t let that slide. So you offered to drive to the coast and find some way of convincing them not to sell it or at least to let it be rented out. Which was how you got to the coastal town of Yuuie. Most of the villagers remembered you, recalling crazy times with you and your gran. They were glad to hear you were going to be at her cottage, but they advised you above all else.
Don’t go walking out at night by the coast.
Most of them said that’s how your grandmother got bewitched by the sirens. You obviously thought that it was just a bunch of townspeople nonsense.
Which is why you made the stupid decision to head down to the coast at night. It was a beautiful night, with the wind blowing cool air in your face, the smell of the sea at your back and salt and sand lined your calves and feet. You smiled in happiness at the beauty of the ocean. It was breathtaking. Even with the moon just over the horizon and the waves deep, dark and abyss like, it still was like no other view you had ever seen.
As you hummed to yourself as you walked the coast, you stopped as you heard something. Floating to your ears, amongst the sounds of the waves crashing against the coast, was a voice. You kept moving forward hearing the voice grow louder and louder. It was singing. Gorgeous singing that had you enchanted before you even realised you were. As you walked forward, almost in a daze, you noticed that the voice wasn’t feminine. It was masculine. A voice unyielded and free. You found yourself heading towards the base of a cliff and giant rocks. You could tell the voice was coming from here.
You moved around and then you found a dark hole that led into the unknown. Thoughtlessly, you followed the voice, having to get on your knees and crawl in. It wasn’t a long crawl until you could stand at your full height. The voice was louder now, echoing in the dark tunnel of the cave walls. Now accompanying the voice was the dripping of water and slight twinkle. You moved deeper, following a luminescent blue light.
Soon you found yourself standing in the darkness, blue light illuminating your face as you were left in shock. Sitting in front of you, on a rock, I shit you not, was a long red-haired being of the sea. Your mouth dropped in shock. They were moving their head side to side as they sang, enjoying the toon of the song. You noticed multiple scars on their back and by their waist was where skin blended into a thick tail that reminded you of a great white shark.
“I don’t know when... I don’t know how...”
You were left flabbergasted.
You had found motherfucking Ariel and you were literally about to cry. “Ariel?”
The singing stopped. “Ariel?” The deep voice asking, turning around to face you was a beautiful face, with ruby red round eyes and thick lashes. “Who in All Might’s seven seas is Arie-” He stopped talking as you both looked at each other face to face. His face dropped once he realised that you were not a mer talking to him. His pupils constricted in fear and worry. “It’s a human...” He stated. “Oh my All Might, it’s a human.” He voiced out in disbelief. For a moment, nothing happened between the both of you. You just stared at one another, shocked to find the other there. You watched as his pupils blew out as he gasped with a bright expression with a smile. It was then you saw razor sharp teeth that were lined to perfection. “A HUMAN!” He shouted in excitement as he held his hands to his face.
Your face was split into one of slight confusion at the sounds he was making. It sounded almost like cat noises. You tilted your head. However, that was short lived as you watched the red head dive into the waves. Your face fell at that. He left.
You took a few steps forward closer to the rocky pool. “Hello.” You voiced out uncertain as you took a few more steps forward. “I’m sorry I scared you.” You apologised. “I promise I won’t kill yo- wow that’s a stupid thing for a human to say.” You voiced out to yourself. You shook your head as you got closer to the glowing pool. You went down on your knees as you brought your face close to the pool, hoping you would be able to see him again. Maybe if you made some high-pitched noises as well, he would come back.
However, you didn’t have to, as not more than a meter away from you, peaking out of the surface were two round red eyes. They looked at you with interest at your presence. You looked at him in surprise to find him back. He tilted his head as he swam closer to you, slowly. You stared right back at him. He stuck his whole head out the water, allowing you to see the gills that were still open underneath the water. He smiled broadly up at you. Even though his smile was lined with sharp teeth that could no doubt cut you with little to no effort, his smile was beautiful. Real and almost as bright as the sun.
“A human. A real human.” He whispered in surprise and excitement. “It has been ages since I’ve talked to one of you guys again. I can’t believe it. I-” You watched as the merman talked to you, but you didn’t understand a word he was saying. It all came out in sharp trills, growls and other noises you couldn’t understand. He seemed really invested in what he was saying to you. You didn’t want to interrupt him but you really wished you knew what he was talking about. “And this is so-” He noticed your expression and his expression dropped. A smile left his face as he stared at you with his mouth in a thin line. He pointed a finger to himself. “You don’t understand me, do you?” He asked. Considering you didn’t answer him back, just staring at him, he took that as a yes. He sighed with a shake of his head.
As fast as lightning, before you could even realise what was going on, he grabbed your head between his hands and pulled your face to meet his. Your eyes widened at the kiss. His eyes closed as he used his tail to reach your height out of the water easily and kiss you. He was rather warm for a fish. His hands were wet but they weren’t slimy like you expected. Before you could even freak out that you were kissing a merman, he sunk back into the water, letting go of you.
“Sorry about that.” You heard him say in your language. Your eyes widened in surprise that he was speaking to you and you could understand him. His voice was much lower and really suited him. It was rather beautiful just like the rest of him. “I forgot you don’t speak Mer.” He spoke truthfully as he scratched the back of his head, in embarrassment with a short giggle. You found him cute. He placed one webbed hand onto his broad chest. “I am Eijiro, of the Kirishima clan.” He introduced with a bow of his head.
“Uh...” You forgot your name. You placed your hand on your chest and followed his actions. “I am Y/N of the... the L/N clan?” You sounded rather unsure whether you were saying that right, but considering his face lit up, you probably did. “Are you a mermaid?”  You asked.
His face scrunched up at the question. “A mermaid! Do I look like a femme to you?” He asked clearly offended by your question. He folded his large strong arms over his chest with a glare.
Your eyes trailed the part of his body that you could see. He had round rather feminine eyes with thick lashes and blinked in a slow way that reminded you of that of a siren effect. He had long thick red hair that pooled around him in the water that suited him perfectly and even his cut-out features seemed soft in some places. His chest was large and broad, thick pecs on his chest with a body covered in muscle but since he seemed rather relaxed, he had a rather soft effect to him. He had a smaller waist though, that made him have a sort of hourglass figure. Honestly, whatever gender he was, he screamed gender envy to you.
You leaned back with your arms up in surrender. He let out a grunt with a huff, happy that you took back your statement wordlessly. He pointed a finger to his chest. “I’m a mershark. A masc Mershark.” He informed you, puffing up his chest a bit more in pride.
That’s when you truly took notice of how big his body was. He was huge, even though he was making himself seem smaller. His broad body was no doubt bigger than yours and if he was out the water, he would no doubt probably be twice your size. He had cute little finned out ears that moved every now and then. You tilted your head as you poked his nose. Kirishima looked down at his nose and twitched it and frowned as he felt his head become a bit lightheaded at the tap. He had a real sensitive nose. He then smiled again and looked back up at you.
“What do you use your nose for?” You asked him.
“To smell!” He grinned up at you. “I breathe through my gills in water, so I only really use my nose for smelling things.” At that last point you heard him sniff. Kirishima moved closer to you as his eyes trained on you in interest. “You... you smell...” He sniffed again, following his nose to the end of the pool.
He was trying to find the scent that followed you. He finally took notice of how you smelled and he wanted to know more. However the pool only went so far. He put his hands on the edge of the pool and with no issue whatsoever, he pushed himself up. Your eyes widened at his large build up close. His large muscle stacked arms, held him above water. Water dripped down his muscles and thick skin as he leaned over down to you. You looked up at him with a heated face as it finally realised that you were faced to face with a predator that could easily take control over you. He sniffed closer to you. At any moment, you got ready to punch him in the nose, just like you would a shark.
He stopped for a moment. “You smell nice. Really nice. What is it?” He asked as he tried to sniff over your body, trying to find the origin. You fell back on your butt trying to put space between him and you as he sniffed you inquisitively. He bent down to sniff at your chest and then down your stomach until he got freakishly close between your legs.
“Oi!” You pushed his face away with your foot. Easily disorientating the mershark. “That’s not nice!” You scold him. You pointed a finger at him in disappointment. You watched as his ears fanned down almost like puppy ears and his pupils went big. He let out a whine as he frowned. It was a cute sound, almost like a sad puppy. “You don’t go around sniffing people d-down... down there.” You frowned, trying to block of your embrassed expression.
Kirishima looked down as he took in what you were saying. “Hm... but that’s how we make friends and introduce ourselves to potential mates.” He told you honestly.
“Well when we want to make friends or... or meet someone, we talk to them, Eijiro. We talk.” You emphasised. “Like how I am talking to you.”
His eyebrows furrowed as he thought over what you said. “So... are we friends?”
You hesitated and shrugged. “If you want to be friends.”
Kirishima’s face lit up as he nodded his head furiously.
That’s how you became friends with your redheaded mershark fellow. With him, you could barely keep track of time, because the hours would just slip by. He was such a sweetheart and really just cared for all of those in his pod and all around him. For a mershark, he really wasn’t vicious or blood thirsty at all. Maybe it scared you at first, how easily his eyes would home in on the fish you would bring for him to snack on, but you soon got used to it. He was funny and great at story telling.
He would tell you stories of when he was just a seapup and would navigate the oceans on his own. Apparently, some mersharks were a lot like regular sharks, lacked the necessary paternal instincts to raise their kin. So once mershark pups would learn to swim and grew in their sharp talons and teeth, they were left on their own. It made you cry when you first heard about it. At first, Kirishima was very confused as to why water was coming out of your eyes, but then he saw it as a sign of sadness. He apologised for making you sad, but you tried telling him that it wasn’t him necessarily making you sad. To make you feel better, he told you about how he had met his aunt and her mate and were raised by them.
“Most sharks are real nice.” He told you as you sat with you feet in the water with him floating on his back, his hands resting on his abdomen. “They really just mind their own business unless their hungry. Mersharks are nice too, but we’re a bit more aggressive.”
“How come?” You asked as you raised your eyebrow at that.
Kirishima hesitated as he thought of an answer to that. “Uh…  It’s hard to explain.” He told you. He sighed as he sunk a bit lower, swimming back to float vertically. He swam closer to you, placing his arms on the edge of the pool, and resting his head on them. “Everyone sees us as predators so we aren’t often received well. It causes some tension and natural bitterness towards others because of it.” He explained to you.
You nodded your head understanding why mersharks might behave in such a way. “Ah…  I see.” You looked down at Kirishima who was looking up at you with wide red eyes. You smiled down at him, placing your hand on his head. You moved your hand to behind his ear to scratch there. “Well, you’re nice Eijiro.” You informed him. This earned you a cute purr like rumble and smile as he leaned into your hand almost like a cat.
He also told you many tales of his adventures and mishaps with, what sounded like a very violent friend, named Katsuki of the Bakugou clan. He was apparently a very pretty but also rather angry merman. A prince apparently. He was the son of the chief of the pod and took his job rather seriously. Kirishima had expressed how he wanted you to meet Bakugou, but the merman was very sceptical of humans, so Kirishima would have to butter him up first.
His pod lived in the area (underwater of course) and hunted in the waters around. The fisherman usually stuck to one side of the coast so they were able to hunt on the other side without harm. They did however hate it when the big ships came by with their large propellers and big nets catching and scaring away all the fish. That was never fun for them. They also didn’t like all the pollution and how the seas were getting warmer. However Kirishima said they were adapting alright, so they should be okay. Besides, the town was rather eco-friendly, so they didn’t have to worry much here.
He told you all about the members of his pod like his best friends Bakugou, Mina Ashido, Hanta Sero, Kaminari Denki and Kyouka Jirou. He also told you more about his aunts, Yua and Takea, that he absolutely adored and loved with all his heart because they took him in. He told you about all the fun traditions the pod had and whenever they migrated to deeper waters for events.
He also told you about how his one friend Tetsutetsu Tetsutetsu, another mershark, had recently just got paired with a mermaid named Istuka Kendo. Apparently being paired was like getting married, but the way he made it sound, made it much more interesting. There was apparently so much food collected for the occasion, then there was some ceremony where they marked each other's shoulders (apparently tapping your nose on someone’s shoulder was a very intimate thing), then there were celebratory games. He had so much to his people and his life that he wanted to tell you, but he also wanted to learn about you.
Like how come humans had little fingers on their feet (toes) and what they were for. Why did you all have short nails and rather blunt teeth. You all seemed really bad at hunting by yourselves. Also why you all liked making so much noise. Why did you give each other rocks when you love each other? Were you coping penguins? Also why do you guys take all the penguins? Why didn’t you guys have gills on your necks? How do you know when a year has passed? Why did you treat your females so differently from your males? Why do you sometimes have more than one mate in a life time? Is it because you have so many choices?
He was really confused with how humans worked an with every one of his questions, you grew more confused in human kind as well.
Over the next few weeks, almost every single day of yours was spent with Kirishima, hidden away in your cave with the giant mershark. Plus, everything was so eased between the two of you, you didn’t think much about your next meeting with him.
“Are you sure this is okay, Eijiro?” You asked him as you sat beside him.
Kirishima lay back in the sand with most of his lower tail in the water for comfort. He nodded his head in affirmation as he tried to stay comfortable. He had his elbows supporting him as he leaned up slightly to keep his eyes on you. “I don’t mind. We’re learning about each other. I think it’s fine.”
You glanced between him and his body. He was indeed as big as you thought he was. If you lay down next to him, you probably would equally to half his height. You carefully brought your finger up to tap his nose. You watched Kirishima’s eyes dilate before he let out an annoyed groan and covered his nose away from you. You giggled at his reaction. He hated whenever you gave his nose any sort of attention. He glared at you but you just giggled. With that out of the way, you looked at the now closed gills on his neck. You leaned closer to them, you tapped one. For a moment nothing happened. You hummed, noting that they stayed closed above water.
Continuing your inspection of him your eyes wondered down to his skin. He seemed to have thicker skin than you, even on his supposed human half. On his arms, you admired the muscles that made them up, watching his large and tough hands with sharp talons for nails. Considering he was a predator, it made sense to you for him to have them. You continued down to his waist area, where tanned skin melded into his great white lower half. You put a hand there trying to feel if there was much of a visible difference. Only slightly.
You turned to him inquisitively. “Does this hurt when I touch it?” You asked.
Kirishima shook his head. “No. Feels normal to me.”
You hummed at his answer, really interested in his anatomy right now. You decided to leave him be and go down to his thick grey tail. You noticed that sharks weren’t smooth like dolphins. They appeared that way but they had small tooth-like scales for skin. You admired how his underbelly was white while the rest of him was more of a dark grey. He seemed to also have more fins than a regular shark. However, you couldn’t get far because you noticed something.
A slit.
You turned your head to the side. It was small, in line with the centre of him and rather hidden away. You had never noticed it before. You wondered what it was for. You raised a finger to touch it.
“I wouldn’t do that if I was you.” Kirishima warned you with a slightly worried expression. He seemed really worried about whatever the slit was and you interacting with it. “It’s getting real close to that time of year and I don’t think you’ll get the reaction you want out of it.”
You glanced between his face and the slit. You then turned to him blank faced. “You’re a femme aren’t you?” You asked him.
Kirishima’s face fell at your question only making you giggle. “For the last time, I’m not a mermaid nor a femme.” He arched his back slightly, raising his lower waist area where your attention was. “If you really want to know, check for yourself.” He raised his hands, almost trying to say that he tried to warn you.
Deciding to go against the loud sirens going off in your head, you decided to touch his slit. At first nothing happened, however you did notice that the area around it was rather soft. You stuck your finger through it, making Kirishima take a sharp inhale at the breach. His face was flushed pink slightly as he looked away from you embarrassed. You removed your finger, noticing a sort of slick like substance leave the slit. You looked at your hands and then down at the slit and then back at him. You were literally about to accuse him of lying to you when you now noticing something peeking out from the slit. You tilted your head in surprise at the sudden appearance of something. You tapped it a few times. It was soft. Smooth but it seemed to be getting harder. It looked eerily like something you had. Before you could comment you then noticed that it was growing.
Rapidly growing.
Until you found yourself face to face with what you could only think of calling, a dick. Actually there were two of them. You tilted your head in wonder at the both of them. You touched one of them making him twitch. You heard Kirishima whine at that. You turned up to look at him. His face flushed as he bit down on his bottom lip, his hands balling up the sand underneath him so that he couldn’t lose control and possibly hurt you. You returned your attention back to his twin cocks. You wrapped your warm hands around the base of them, your fingers couldn’t even touch. It was coated in that slick like substance you notice earlier. You moved your hand up and down and then you noticed from the end of it, a white substance, trickled down in a drop.
Kirishima let out a soft groan. “If... if you... I don’t want to hurt you. It’s close to mating season and I really don’t want to harm you.” He let out worried for your safety.
“Do I... do I just put it… them… back?” You asked.
“Uh no...” He let out nervously with a chuckle. “They sorta just goes back on their own after a while. Just ignore them.”
“Well it’s kinda hard to ignore when your cocks are out, Eijiro.”
Kirishima furrowed his eyebrows and tilted his head. “I don’t know what a ‘cock’ is, b-but...” Kirishima closed his eyes briefly as he relaxed for a moment. You hadn’t stopped your touching or prodding on him. He let out a soft moan, trying to remember what he was saying before getting lost in the pleasure that he scarcely felt outside of mating season. “I... I don’t think I have that. Those...” He pointed down to what you were still holding in your hand. “Those are tendrils.”
“Why do you need two of them?” You asked shocked. He shrugged as an answer to your question. You looked between him and his coc-... tendrils? Yah you weren’t calling them that. You sighed feeling ass though you had put yourself into quite the situation that you didn’t know how to get out of. Well, at least you could cross off giving a hand job to a merman off your list. “Seems like we need to put them away then.”
“H-How…” Kirishima looked at you hesitantly. “How are you going to do th- Fuck!” He moaned out as you licked the heads of his cocks. You moved your head back shocked that he didn’t taste as salty as you thought. You hummed as you brought your mouth to the head of one while you moved your hand up and down the other. Kirishima whimpered at the feeling of your hot mouth on his cocks. He didn’t understand why you had put your mouth there, no one was supposed to do that, but at the same time, it felt so good that he didn’t want to tell you to stop. “Oh... oh fuck. That’s... that’s good.” He expressed to you, his eyes closed as he tried to control himself and not grab onto you and probably fuck your face.
You tried to focus on dragging your tongue around his sensitive length. He was pretty vocal but tried to hide it by biting down on his bottom lip and partially covering his mouth with his hand. The sounds he released went straight to your sex, only encouraging you more and more. You continued to move your hand up and down his other cock, using the precum that dribbled out of it to make gliding your hand easier.
He wiggled and writhed in your grasp. Kirishima tried so hard not to hurt you. He really didn’t want to hurt you, but you were making it so hard for him to push his instincts back. You were making it so hard not to just grab you and rut against you as if he had no other goal in life. “Fuck, I’m sorry. I’m so sorry but...” Kirishima apologised profusely as he brought his hands down to the back of your head. “I’m so sorry but I need your mouth.” He apologised as he forced you down around his cock till he was hitting the back of your throat. He bit down on his bottom lip, his eyes rolling back in ecstasy. He groaned out loudly as he held you down. Tears sprung in your eyes as you chocked against his cock, you tightened your hand around the other as you braced yourself against his tail. Remembering that you couldn’t breathe, Kirishima pulled you off his cock for a second.
You gasped, saliva dribbling out of your mouth. “Holy-” You didn’t even get to finish your two word sentence as you mouth was forced back onto his cock, your warm cavern providing shelter for the normally cold blooded mer underneath you. Kirishima whimered at the feeling as you swallowed around him, trying to take him in deeper.
“Oh my All Might’s seas.... fuck... I’m gonna cum. I’m... I- I'm so sorry but you’re just so...” Kirishima groaned as you held you down for a few seconds. That’s when you noticed the twitching of his cocks and the sudden explosion of cum in your mouth. Kirishima rolled his eyes back with a moan as he thrust into your mouth. You choked almost immediately at the overwhelming amount of it all in your mouth. You tried to swallow as much as you could but coughed, removing your head gasping for air.
You coughed at finally able to breathe. You sat back trying to finally get air back to your lungs. Unlucky for you, Kirishima was far from finished. Suddenly you found yourself on your back. You coughed as you looked down at the huge mershark that now had you pinned to the sandy floor of the cave you were in. “E-Eijiro... Wha...” You tried to cough out, but everything you were saying was met with a silent mershark on a mission. His pupils huge as he was trained on your body underneath him.
He spread your legs easily, pulling at your short and easily tearing through them with his claws. You gasped at the violent action as he found himself finally face to face with your sex. He stopped for a moment, taking notice of how different it was from femme mers. He moved slightly back, settling between your legs as he watched your sex. It was already glistening with slick which he knew as a good thing. He sniffed again, affirming that he was right. The nice smell was coming from you. Inside you most probably.
Maybe you humans also got affected by pheromones too. He sure hoped so.
Kirishima’s mouth got closer and closer to your sex. “Uh... Eij...” His eyes flicked up to you. You looked embarrassed as you looked down at him. You squirmed under his heated gaze. “Be careful with the teeth.” It was then that he remembered he couldn’t just, quite literally, eat you.
He nodded and without another word, he licked up your slit making you tense. His hands easily gripped your thighs as to hold them in place to allow him to access you without hindrance. Kirishima groaned as he moved back, his eyes practically black as his pupils took most of his eyes. He seemed to find his new favourite place. Deciding to dive back in, he licked and sucked at your sex making you whimper and squirm.
For a man who was half fish, he seemed to be really excited about this. Really excited, because it felt as though you couldn’t catch a break with him. You whimpered as your thighs tensed around him. Kirishima flicked his tongue up by your clit. You thrusted down against his face on instinct and he stopped for a moment. You had let out a moan that was louder than the rest. So clearly that was a sensitive spot. Focusing on the nub that was starting to harden and make itself known, Kirishima gripped you harder as he sucked against you.
Your hands balled up the sand as you moaned, grinding down against his face. You were too caught in ecstasy to care about much else. You moved one hand to bury itself in his red locks of hair. You pulled him closer to your sex, wanting him- no... needing him closer. You whined and cried out as he continued his onslaught against you. Lapping and drinking you up as if he was a man starved, as if there was no greater thing in life than to serve you and give you pleasure.
Kirishima wiggled squirmed in the sand, already lost in your pleasure alongside you. “O-oh. Oh fuck, Eijiro.” You whimpered as you felt the coil in your stomach tighten as your thighs started to tremble. You felt your heartbeat increase as you knew you were going to fall off the cliff of pleasure, hard and fast. “Shit! Shit. Eijiro I-” You tensed for a moment, before rolling your eyes back and moaning loudly. “Fuck!” He didn’t stop as he continued to suck on your clit and lick up your slit, prodding at your hole in alternating movements. You were tense as you came hard against his mouth. You finally relaxed down against the sand, your breathing heavy and your eyes closed in relief.
However, Kirishima didn’t get the hint. He continued lapping you up, not letting a drop of your slick escape his tongue as he viciously continued to eat you out. You whimpered at the overstimulation as you started to quiver in his hold. Your whimpers sounded like music to his ears as he continued to lick and lap at you.
Then Kirishima heard a chirp. He stopped for a moment and turned his head away from you to look at the pool behind him.
Staring with judgement was another set of red crimson eyes. They glared for a moment, looking at you and then at Kirishima. The mysterious mer had blond hair that fell down with the water. Kirishima perked up at the familiar face. He smiled broadly, slick and cum dripping from his chin and face as he looked over at his friend. He then glanced at your still heavily breathing state, with your legs spread wide for the blond’s eyes to also see. “Look Y/N, it’s Katsuki!” He told you, but you weren’t really listening as you tried to finally relax and catch your breath.
Kirishima pulled his body over to the water closer to the blond. The blond lifted the rest of his head out of the water, orange finned ears moving down as he hissed at Kirishima almost scolding him. Kirishima seemed unbothered with the hostility as he chirped over at Bakugou.
“Shitty hair, what the fuck are you doing?” Bakugou asked glancing between you and the redhead mershark. “Eating a human! You know how much serious trouble you can get into for doing that!” He reminded Kirishima. Eating humans was forbidden now, due to how advanced and determined humans were when one of them died. “It could put the whole pod at risk.”
“Come on, Katsuki. I’m not eating them! I’m just licking and tasting. Don’t you want a taste too!” He asked with a whine as he moved closer to the blond.
Bakugou’s eyebrows bunched up in confusion as he looked at the redhead with judging eyes. “Taste of wh-” He was interrupted as Kirishima’s lips were on his.
Now that caught your attention. You moved your head up to find the two mers sharing a kiss. Kirishima was first to move back, happily glad about what he had done. He had a grin on his face as he looked at the blond mer. Bakugou licked his lips, tasting you on his mouth. He didn’t say anything. You watched as the blond mers’ pupils went wide as he turned his eyes to you. Specifically, to your sex that he could still see easily. You knew that predatorily gaze.
You tensed.
Fuck.
Now there were two of them.

Thank you for the prompts! I kind of got inspired/combined two of your prompts, mermen KiriBaku and nonsexual intimacy!
This one could be a stand alone or could be a continuation of my series A.S.A.H. (All Sharks Are Himbos). Whatever you prefer!
Hope you enjoy!
-----My Siren Gets Clean-----
Bakugou brushed a coral comb through Kirishima's hair, allowing himself a moment of peace hidden away in their den. 
"Hey."
Bakugou hummed, looking down to see Kirishima's eyes peeking open to stare at him. The bull shark mer immediately smiled once Bakugou met his gaze, the affection clear enough to send a blush to Bakugou's face. 
"I wanted to ask…before you did it yourself," Kirishima said, "could I help you this month? With your cleaning?"
If Bakugou had thought he was blushing before, that was nothing compared to now. His face was as red as the tips of his fins as he shoved Kirishima off him. 
"The fuck?! You can't just ask to–"
"I'm sorry!" Kirishima shouted over him. "I don't mean to pressure you! If you're not ready–"
"Who said I wasn't ready?!" Bakugou demanded.
"No one, I just mean that it's a really personal ask, if you want to wait, that's totally cool! Or if you never want my help, that's also fine! I'm sorry I brought it up so suddenly." 
Bakugou crossed his arms, embarrassed and frustrated. He wasn't angry at Kirishima; it was a fair ask since they'd been courting for months, and they'd both already accepted the courtship for good. It was just an embarrassing thing for Bakugou. 
Sirens–unlike most marine species–tended to sing while sitting on reefs or rocks or other things above the waterline. They were one of the few species able to stay in the air for extended periods. However, the trade off of this was that on occasion they had to clean off any pesky barnacles or algae that clung to them in…delicate places due to the constant transition between spaces. Bakugou honestly hated that time of the month, and if he wasn't so careful about maintaining his own health, he might even skip it for the awkwardness alone. There were…certain areas that required additional eyes and hands to get to, and he despised letting other sirens assist. Most of them avoided him when it came time for the task, though he had a handful of other mer he would forcibly wrangle into helping him, depending on which was the least painful at the time.
So no, he wasn't mad that Kirishima might be interested in helping him. He was more mad that it was even necessary. Still, the longer he thought about it, it would probably be less painful to direct Kirishima in where to look versus having to deal with Uraraka's chipper attitude or stupid Deku's constant muttering about him changing colors or new fin growth.
"This isn't a yes," Bakugou warned, pointing at him, "but it's not a no either. Let me think about it."
Kirishima beamed, bumbling closer in the already tight den so he could wrap Bakugou up in his arms, accidentally scraping Bakugou's lower half with the rough hide of his tail. "Whatever your choice, I'll accept," Kirishima promised, as if Bakugou had any doubt. "I'm really happy you'd even consider it."
"Well fuck, you're going to be my mate, aren't you?" Bakugou mumbled, looking away. "Not like you won't see everything eventually anyways."
Kirishima squeezed him even harder, like he couldn't contain his enthusiasm at the idea. 
…..
"Fuck, okay," Bakugou said, fins fluttering stiffly. "You're a brute, so be fucking careful, alright? I don't need my backside fileted. Most sirens use shells to get the barnacles off, but you can probably manage fine with your nails since they're so hard." Bakugou studied Kirishima's hand, not at all stalling. 
"Hey," Kirishima called, gently pushing Bakugou's head up until he met his gaze. "I promise to be gentle. I want to help you, Katsuki." He leaned closer, nuzzling under an earfin, softly setting his teeth against his skin in a shark's kiss. 
Bakugou sighed, relaxing against him. "Okay," he agreed. Kirishima smiled, nipping his jaw before he grabbed Bakugou by his hips and turned him around.  
There was a level of humiliation when it came to his monthly cleaning that Bakugou hated. Having to swim upside down was awkward enough, but having to flare out all of his fins and leaving himself on display while someone inspected him wasn't his idea of a good time. Bakugou, in another unfortunate genetic lottery fact, was related to the lionfish species, meaning he had a lot of fins, which was the main reason he wasn't able to get to them all by himself.
Bakugou tried to just put it all outside his mind as he had to do every month when Deku or Uraraka handled this for him, and he rolled over, fanning out his fins for Kirishima's assessment. 
"Wow."
Kirishima's quiet exclamation immediately had him on high alert, tensing. 
"What?" He demanded harshly. "Just because I'm–"
"You're beautiful," Kirishima said, cutting through Bakugou's defensiveness with his quiet adoration. His hands brushed across a few of the thinner fins, leaving Bakugou shivering. "Are you steady? You can hold onto my tail if that helps."
Kirishima started to comb his fingers through the forest of prickly fins from Bakugou's tail. At the first catch of a stray barnacle, Kirishima's fingers deftly plucked it off without pause, and Bakugou was immediately sent reeling at such a soft touch compared the shell-fight the others usually had to put up with to get him clean. He slammed his eyes shut at the well of vulnerability, reaching out blindly for the shark mer's tail and just hanging on, not unlike a seahorse tangled with its mate. He took a few deep breaths, relaxing against the other as two more barnacles were removed from their annoying hiding spot, Kirishima soothing the irritated scales with his fingers before moving on. 
Cleaning Bakugou took hours of meticulous work, but Kirishima didn't complain once. He even started humming partway through, and Bakugou could feel the sounds thrumming through his entire body. He didn't feel uncomfortable and adrift anymore; he just felt held, cared for. Kirishima's touch was never aggressive and he was methodical in moving through Bakugou's fins so he didn't miss a single spot. Eventually Bakugou's tail found itself wrapped over the shark mer's shoulder, the blond siren completely lax against Kirishima who wasn't even slightly phased at having to hold Bakugou's weight while grooming the blond's tail. 
"Almost done, I think," Kirishima murmured quietly, one hand resting on the small of Bakugou's back as he held the other close while his other hand combed through the last of Bakugou's dorsal fins and spines. 
Bakugou could only hum in response, feeling too settled to do anything else. 
"There we go," Kirishima announced, now just holding Bakugou. "You okay?"
"I'm good," Bakugou said drowsily, blinking slowly. 
"Wasn't so bad," Kirishima teased him, gently coaxing him back upright. "You're usually ready to fight whenever you have a cleaning, but now you're just a jellyfish puddle. Are you sure I did it right?" 
"You did it fucking perfectly," Bakugou assured him, wiggling and twisting his tail and spines to make sure he couldn't feel any barnacles still clinging to him. He felt cleaner than usual even, like Kirishima may have found a few hanger-ons that had been missed in prior months. 
Kirishima smiled, hands resting on Bakugou's hips. "I did? So I can do it again, maybe?" 
Bakugou actually looked at him then, surprised to see genuine pleasure and hope on his face. Siren cleaning was a boring chore every month, why would he want to do it when he didn't have to?
"I guess," Bakugou agreed with a shrug, "if you want to. Whatever. Sure."
Kirishima's tail wriggled happily and he immediately swept Bakugou into a tight embrace. "Thanks, Katsuki! I promise to do my best every time!"
Bakugou blinked, a bit taken aback by his enthusiasm, but slowly managed to relax into his hold. "Idiot," he accused, even as he softly ran his clawed hands up the other's strong back, returning the hug. 
He'd never understand shark mers.

spooky season has my mind clouded with fic ideas.
blood kink with vampire bakugou who promises not to drink too much from you but ends up losing control as soon as the sweet taste of your blood pours down his throat, sinking his teeth deeper into you, greedily drinking you up.
or teasing your explosive vampire lover as you accidentally cut your finger while chopping vegetables for dinner. sucking on your digit as you smear blood against your soft lips, making him feral.
corruption is specially hard on my mind right now. fallen angel katsuki falling for the pretty human he swore to protect. his wings slowly turning black as he buries himself deeper inside you.
priest bakugou exorcizing demon reader. drinking holy water from his flask and spitting it down your awaiting mouth, the burning in your throat just making your aching cunt spill more of your juices onto the old wooden floor of the church.
nun reader begging demon king bakugou to spare their life after slaughtering the entire church, making you worship him as your new god until his name is engraved into your skin, just above your uterus as you give yourself to him. corrupting you softly until you make a contract with him, engraving the seal right on your cervix to remind you of who you belong to now, who your real god is.
fear kink and breeding kink with werewolves kiribaku fighting over who gets to breed you first after tormenting you for hours inside the dark forest. eventually shoving both of their swollen knots inside you, stuffing your holes and filling you with cum.
