Escaping the royal navy’s ship on a rowboat and wandering aimlessly through sea until you could find land, was not the ideal evening you had planned. Wanting nothing more than to be within the comfort of your chambers, enjoying a good book while snug under some warm blankets. But as the first and only daughter of the governor, your life always revolved around expectations as a demure lady. Envisioned to marry a respectable man, equally well-born or superior to your rank to forge strategic political alliances and social connections for your father. 

Which is how you found yourself en route to the Royal City to marry a commodore who was a respected royal navy officer. You had no interest in being wed for politics, you much preferred to marry out of love, but your father was insistent that you accepted the commodore’s proposal. That was until the ship was ambushed and raided by pirates, the commotion working in your favor as you took the opportunity to slither away unnoticed. 

Your clothes were wet from jumping into the water in a hurry, out of fear of being spotted, and they felt uncomfortably tight against your skin. Already starting to feel tired from rowing, but pushing through the ache in your muscles, not wanting to risk someone catching up to you. Beginning to lose hope of finding anything that could help you in this darkness, with just the light from the moon illuminating your path, only to sail over waters that seem to shine when you pass through them, bioluminescent waters that glow blue when agitated.

Stories of deadly creatures living in these waters were commonly told by sailors after they returned from long journeys across the deep sea, but no one ever truly believed that such things could exist. 

You stop rowing to lean over the edge and touch the water. The fish and small crabs swimming around you make the water shine, brightening enough to allow you to see better around you. Taking this as an opportunity to remove your wet clothes, as you lay them down behind you to dry and recline over the side of the boat, resting your head on your forearm while you dip your hand into the water, the glow emitting from your movements illuminating your features. You wouldn’t be able to spot any land in this darkness so staying afloat where you at least have some light is your best option. Exhaustion catching up to you as you feel yourself drifting to sleep, before you felt the waves shift under you, making the boat sway a little harder.

You whipped your head quickly from side to side but didn’t notice anything unusual. Staying on the lookout for a few moments before settling back down to your previous spot, maybe you were just imagining things. But it wasn’t long before you felt the same jerk of the boat, a splash resonating right afterwards making you sit up again and peek over the other side. There was a large patch of blue sparkles in the water, a long trail leading towards your boat and disappearing just under it, indicating something big had just passed through. Nerves started to creep up your spine, you had nothing to defend yourself with if a large fish decided to attack and you couldn’t use your paddles, you needed those to row into land and not risk being stuck at sea. 

Trying your best to stay still, you waited to see if whatever it was that altered the water would appear again. Wrapping your arms around yourself as your eyes darted all around. You were naked and defenseless, thankful that at least the water was still warm, expelling the heat it absorbed from the intense sun during the day. 

Your eyes drifted over to your side again, distracted by the small fish jumping up and down the water to catch some small prey flying above it, causing the water to glow more and more with each jump. But you failed to notice the large figure stalking towards you from a few feet away, only becoming aware once it reached the front of the boat when you felt it rock gently under you, as if it was being held by something.

You were frozen on your spot, whatever is in these waters with you is hidden behind the bow of the boat. Swallowing the lump in your throat, you force your body to slowly approach the front edge, hands gripping the wood as you peek over the ledge. 

A spark of color is the first thing that catches your eyes, pastel orange scales that turn iridescent under the moonlight coating a long luminous tail. Black fins at the end and protruding from its sides that sparkled a deep shade of green when they caught the light each time they rose from the water. Its center is composed of highly developed and toned muscles similar to that of a human’s physique that made your breath hitch in your throat. Trailing your eyes up to its face, you're met with intense vermilion irises staring back at you. It had the features of a human male except for the patches of scales on his skin that matched the ones on his tail. His wet blonde hair glossy under the moonshine as it draped over his forehead. Small gills adorned the side of his neck while spiky fins expelled from behind his ears, the orange on them a little darker than the one on his tail.

Distracted with the appearance of the creature before you, shocked with what you were seeing, you were startled when he slowly rose from the water to come face to face with you. Curious eyes trailing over your features as his head tilts to the side, wandering down your figure and stopping on your legs, focusing on them for a few moments before his eyes shoot back up to your face. 

Placing his hands on the edge of the boat near yours, you let your eyes drop to them. Scales covered the skin on the back of his hands and trailed up his forearms, disappearing just before his elbows. Strange webbing stretched between his fingers that looked almost transparent. And claws, long and sharp enough to rip through flesh. When you tear your eyes away from his hands, lifting your head up to look back at him, a small gasp leaves your lips as you notice how much closer he is to your face. He was beautiful, smooth soft tanned skin that glimmered under the moonlight, his fins twitching with every rise and fall from your chest, complementing his chiseled jawline. Rosy plump lips that make you lick yours subconsciously, the action not going unnoticed by him as he stares down at your lips, shiny and slick.

Mimicking your actions, his tongue darts out of his mouth to lick his lips, the wet muscle long and pale. Allowing you to catch a glimpse of his sharp teeth, the sight making your chest rise harder as you take in a deep breath, his fins twitching at the sound again. You capture his eyes again, deep pools of red throwing you in a haze as you get lost in the intensity from them, only the loud sound of his wide tail splashing against the water pulling you from your hypnosis as you take a quick peek at the long limb, finding the iridescent scales dancing under the moonshine with every movement of his tail captivating. 

The stories you've read about the man-eating monsters that supposedly lived in these waters never mentioned that such mesmerizing creatures could also be roaming in them. They told tales of hideous things that would stalk and toy with their prey, rumored to have magical powers that allowed them to control the weather to sink ships into the depths of the ocean and eat their unfortunate passengers. But you found it hard to believe that the beauty before you could spawn such chaos. A beauty so alluring that you had to retain from reaching out to touch him, feeling your hands twitch with the desire to do so, but your mind still held a hint of fear towards the mysterious soul.

Too caught in your own head, you jolted when the creature hoisted himself up into the front of the boat, his tail hanging off of the ledge, still splashing it in the water creating more and more blue sparkles around you. Making you crawl backwards into your original spot at the center of the boat, your chest heaving as fear started to sink into your skin once again, unsure of what the creature's intentions were. 

Your legs were sprawled open in front of him, when you noticed his eyes trailing down your body and settling on your exposed sex. He licked his lips again, this time at the sight of you presenting yourself to him. The action makes you jump as you quickly close your legs and bring them near to your chest, realizing your mistake. A dissatisfied grunt resonating from deep in his chest at your reaction as he gets closer to you, webbed hands reaching for your leg as he drags his fingers softly across your skin. Stroking up and down your calf before firmly wrapping around your ankle, repeating the action on your other leg before prying them open for him. 

Suddenly pulling you towards him so your cunt is right in front of his face, the abruptness making you yelp as you stare deep into his eyes, his tail swinging behind him while he stares back at you. Caressing your legs again before he rips his eyes away from yours and settles them down on your cunt. Darting his long tongue out to take a scrutinizing lick through your folds. A soft gasp leaving you both as your eyes meet again, the fins on the side of his face twitching rapidly at the taste of you before his tongue starts licking your cunt more eagerly. Soft mewls burst from your chest, the feeling of his wet, icy cold tongue darting feverishly through your folds foreign to you as it sends shivers across your body.

You've never been intimate with anyone, being taught that you needed to save your purity for marriage. The only intimacy you've experienced is the rare times you would allow yourself to succumb to your sinful thoughts and bury your digits deep inside your own warmth, letting your fantasies drift you into bliss within the privacy of your chambers late at night. You had always expected that your first time would've been one of law and order with a man fitting for your standings and one pleasing for your father. One to be witnessed by a priest to ensure your communion was pure and true at the night of your wedding. But all those thoughts were now drifting away by the currents of the sea and replaced by the creature between your legs. 

His tongue was driving you insane, thick globs of saliva dripping from his mouth and onto your already sloppy pussy. Grunts and mewls vibrating in his throat as he flicks it up and down your parted folds, webbed hands wrapping around your plump thighs as his claws dig lightly into your smooth skin, not hard enough to break through it but firm enough to leave red lines and pointed indents in their wake. 

He circled his tongue on your entrance before pushing the tip into your slick pussy. The intrusion rips a moan from you while your walls clench around the wet muscle. His eyes dart towards your face as he slows down his movements, slowly bullying his way against your pulsing walls as he stares at you, scraping his nails on your skin to soothe your nerves while he curls his tongue back and forth until it's fully settled inside you. Making you feel so full that you almost couldn't breathe, your mind clouded with pleasure as you allow this man… this creature to have its way with you.

He stays buried in you, blown out eyes looking back at your glossy ones before he begins to pump his tongue in and out of you. Starting slow and gradually increasing his speed as he brings his open mouth down to latch around your cunt and suck on your folds. Your moans echoing throughout the quiet sea for the waves to swallow as you feel a pressure build deep inside your lower abdomen, pressure similar to the one you've felt with yourself but far more intense than you could have imagined. 

Your body was shaking and a thin layer of sweat was coating your skin as heat courses through your body. Your orgasm hitting you so hard that you barely had time to register what was happening as your vision got blurry. Legs twitching as the creature between them continued his assault on your cunt, tongue lapping up your release while he continued pumping it against your silken walls. Sharp nails digging a little harder against your skin when he grips your thighs to prevent you from closing them around him, feeling the skin tear under them as blood begins to trail down along the webs of his digits whilst he continues sucking on your folds. 

Your moans turning hoarse from the overstimulation, as you feel the pressure build up again but this one was slightly different from the last. You felt… funny in a way, you couldn't really describe it since you've never felt this way before. Darting your hand towards his webbed one as you wrapped it around his, his fingers opening up for you to hold onto as your blood now transferred to your palms as well.

“Wait, I-I feel…I feel-…” you could barely finish your sentence when you felt the knot inside you burst, a stream of clear liquid gushing from your cunt and pouring down his throat as he greedily drank up your fluids, splashing from the sides of his mouth making his wet skin glisten under the moonlight. 

Your breathing was erratic, goosebumps erupting from your skin as chills ran across your body, your skin glowing with sweat and your nipples were pebbled. He slowly pulled his tongue from your warm walls, running it through the length of your pussy before licking his lips, cleaning your release from his face as he closed his eyes, savoring the taste of you on his tongue. Slowly opening them again, finding yours already staring back at him with pure bliss adorning your face while soft pants left your lips, a small cloud of air forming with every exhale as it drifts into the wind. 

You watched as he lowered himself down to your cunt again and nuzzled his nose against your clit, taking a deep inhale to breathe in your sinful smell. Closing his eyes again as if to memorize your scent before giving it a quick lick and slowly crawling his way up towards you. Nose running up the skin on your abdomen, gently breathing you in again before lapping up the thin layer of sweat from your skin. Dragging his tongue all the way up through the valley of your breast and leaning back to stare at your chest.

Erect nipples catching his attention as he brings his clawed fingers down to flick on one of them. Causing you to capture your lower lip between your teeth as you continue to watch his every move, his eyes shifting from one nipple to the other before pinching a peak between his digits. Coaxing a moan to erupt from your throat when he pulls and twists the sensitive bud, his eyes shifting towards your face momentarily before repeating the action on your neglected nipple, your back arching against his touch while more moans rip from you. You've played with your nipples before when you pleasured yourself, but the feeling of someone else touching you in such erotic ways was making your clit pulse again and your thighs to clench. 

Your eyes were glossy again from all the attention you were receiving, your mind completely clouded with lust as this creature continued pleasing you, his curious hands roaming every part of your body as he continued exploring every inch of you. Lowering his tongue down onto your nipples as he flicked it against the swollen bud, webbed hand grabbing your breast, pulling it towards his mouth as he wraps his lips around it. Sucking hard on your skin while he slowly moved his head back and forth before releasing your tit with a wet pop, threads of spit connecting his drooling mouth with your soaked breast while lustful eyes stared back into yours.

Giving your nipple a quick final lick before switching towards the other. Already swollen and a little bruised from his fingers as he darted his tongue out to lick up and down right on the center of it at a tantalizing pace while he stares up at you. The tears clouding your vision spilling down your temples as his hot tongue lapped at your chest, the contrast in temperature from his initially freezing tongue feels so good against your skin, making your pussy clench around nothing as you feel yourself getting closer to another orgasm just from the stimulation on your chest. 

Unable to resist the pulsing on your clit as you bring your fingers down onto the nub and start rubbing fast circles on it. The action not going unnoticed by the scaled man as he wraps his lips around your nipple, continuing to flick his tongue faster inside of his mouth as you arch your back, pushing further into him. The knot in your stomach bursting as soon as it builds, throwing your head back as breathy moans escape your lips while your arousal drips into the wooden floor of the small boat. You run your fingers through your messy pussy to collect your fluids, bringing your digits up to your mouth as you suck on your fingers, tasting yourself while you stare down at the creature still sucking on your nipple. Dipping your fingers back down to collect more before lifting them up to your lips again, the fins on his head flicking rapidly all of a sudden as he removes his tongue from your breast, a wet slurp echoing in the wind as he brings his face closer to yours.

His eyes staring at your fingers stuffed inside your mouth as a webbed hand wraps around yours to pull your fingers out of your mouth and into his. Eagerly sucking the mixture of cum and spit from your digits, a whine vibrating from his throat followed by a soft purring, similar to that of a cat as his eyes open and close softly, his brows rising in the center as another whine rips from his throat, muffled by your fingers in his warm mouth.

Pulling your fingers out of his mouth, he leads your hand back down onto your cunt, collecting your release again before presenting your hand towards your lips once more. Quickly parting them as you run your tongue against the underside of your digits, licking from where your fingers meet your palm all the way up towards the tips and repeating the action. His eyes never leave yours as he brings his face closer to you, his tongue meeting yours when he licks the top of your fingers, mirroring your actions as he licks from your knuckles and up towards the tips. His tongue rubbing against yours in between your digits as your hot breaths mix with each other and drift into the cold air. 

The feeling of cold claws barely digging into the back of your neck is the only warning you get before he pulls you towards him, pressing his lips against yours. His tongue dragging across your bottom lip before he pushes it past them and down your throat, lips stretching wider and wider as he thrusts the large wet muscle in and out of your throat. Thick webs of saliva spilling from the sides of your mouth as it dribbles down on your chest. The feeling of having your mouth so full making your eyes roll as fresh tears gloss over them while the sinful squelch resonating from deep inside your throat causes the muscles in your thighs to tense, wanting to rub your thighs together to relieve the ache building on your clit again, but unable to do so from the creature hovering his waist between your legs.

The lack of air is intoxicating, feeling the pressure build in your head as your  hands reach up to hold onto his muscular shoulder while your nails dig into the scaled skin, leaving crescent moons in their wake. A muzzled high pitched whine vibrating from your chest, begging him to give you a moment to breathe, to which he complies as he starts to retract his tongue from you. Frantically breathing air back into your lungs while he leans down to lick the drool on your chest, not giving you much time to recuperate as he lifts his head back up, nails digging into your nape again as he pulls you closer. 

“Wait!..”, you scream while pressing a hand on his chest, big red eyes staring expectantly back into yours as his fins flickers back and forth rapidly, noticing how his gills open and close softly on the side of his neck. 

“I need a minute Mr…”, you said in a breathy sigh as you trail off, unsure of what to call the creature staring back at you. 

“Bakugou.” Your eyes widened, your breath stuck in your chest again and your parted lips stilling, unsure if you heard correctly or if your ears were deceiving you.

An almost inaudible ‘what?’ leaving your lips as you stare at him, confusion written all over your features. 

“Bakugou”, he repeats. This time you hear it clearly, his raspy voice sinking deep into your ears as your eyes flutter. 

“You-you can speak?”, he responds with a nod as you feel his claws draw ovals on your nape, tangling with your damped hairs as you both continue to stare at each other, taking this opportunity to catch your breath while you try to calm your thoughts that are going wild with this new revelation. 

All the tales you've been told before about the creatures that lived in waters like these never mentioned anything about them being able to speak the common tongue, curiosity overtaking the better of you, wanting to know more about him and what his intentions with you really were. 

“What um- what are you?”, you ask after taking one last big breath to settle down, noticing how his eyes continued to shift down to your exposed chest with each inhale before meeting yours again.

“A merman”, he answers back briefly as he starts to untangle his claws from your nape and run them softly down the side of your neck to hook them under the thin chain of your necklace before settling on the small pendant in the center. Looking down to where his clawed fingers are holding the golden coin remembering when you first received it many years ago, back when you didn't have so many obligations and was still allowed to explore the town without limitations. 

You would visit the docks when fishermen would return from big expeditions and watch as they unloaded their ships with all kinds of things they found in their journeys, remembering how you would sneak into Mr. Aizawa’s ship to get a first look of the different animals he would import back from other lands to expand his market, until he found you one day whilst you were distracted looking at the remains of what looked like a shark, although you've never seen one before that time, you had read about them.

“You lost, little one?”, Aizawa startles you as he circles around you to cover the carcass with an old cotton sheet.

“My apologies sir, I- I just wanted to see the animals, please don’t tell my father”, you begged him as you fisted your dress with your head down.

He stared down at you for a moment before patting your head, messing up the pristine hairstyle your mother had done for you that morning, after all you were the daughter of his highest paying customer, so it was in his best interest to avoid any conflict.

“Relax…”, he breathes out whilst crouching down to your level, “... I won't tell if you don't”, he whispers while shooting you a wink, making you smile back at him as you offer him a nod in agreement. Your eyes drift behind him as they fixate back to where you were staring at the carcass, asking Mr. Aizawa what it was as your curiosity gets the better of you. 

“You don't want to know'', he says as he stands up straight, extending his hand towards the other cages below deck to shift your interests elsewhere. 

“Is it a shark?”, you ask while walking along with him, looking over your shoulder towards where its tail is still peeking out from under the cover, long purple-ish scales catching your attention before Mr. Aizawa’s hand obstructs your vision.

“Something like that”, is all he says before he encourages you forward towards the small cage with small round furry animals he calls rabbits, successfully shifting your curiosity elsewhere as you crouch down to pet the small creatures.

Later walking you out onto the docks to send you off back home safely, the sun shining against the rows of different golden chains and beaded jewelry around his neck catching your eye as he notices you staring at them. 

“You like ‘em”, he asks while crouching down to your level again. 

You nod at him while pointing at one with a skull on it and foreign figures around it, “what does this one mean?”

He looks down at the one you're pointing at before reaching up to untangle it from the others as he presents it to you, “this one is a gold medallion”.

“What is it used for?”, you asked while tracing your fingers along the designs, feeling the shape of each indentation before tracing the skull at the center. 

“Mm not sure, found it on one of my expeditions south of the Caribbean Sea… you like it?”, he asks as you meet his dark eyes, shifting your gaze towards his black strands of hair trapped inside beads of different colors and sizes matching the ones around his neck and wrists, looking down at the medallion again before nodding as you glance back up at him.

“Here…”, he breathes out while reaching up to place it over your head and secure it around your neck, “... you take care of it for me, yeah?”

“Really?!”, you ask excitedly as you run your fingers along the skull again.

“Mhm, but be careful with it, okay?, golden medallions are made of ancient aztec gold that is quite important and are very seeked out by pirates”, he warns while pointing a black nailed finger at you to which you quickly glance at before eagerly nodding again. 

“Very well, now go on before your father comes looking for you”, he says as he waves you off, quickly thanking him before saying your goodbyes as you hurriedly make your way back to the manor whilst hiding the necklace under the ruffles of the neckline of your dress. 

Aizawa watches you from a distance as he takes in a deep inhale, relieved he got rid of that little problem for the time being until destiny decides to unite you both again.

Those were simpler times you supposed, although never in a million years would you have thought to find yourself in the situation you were in right now, with a merman laying across your stowaway boat, his tail so long that is hanging off of the edge with some decent amount of length still hidden under the bioluminescent waves whilst he traced his clawed digits along your medallion, his other webbed hand caressing your sides as his eyes roamed along your body, feasting on your exposed skin. 

Feeling his mouth begin to salivate at the sight of your pert nipples as he begins to lower himself to your chest before he feels your sides tremble under his grasp making him stop as he looks up at you, noticing how your jaw is now shut tight. Tilting his head from side to side as he studies you whilst you stare back at him, your hand lightly touching the scales on his shoulder feeling their texture change depending on the direction you caress them. His fins flicked occasionally, but not as rapidly as before as if he was waiting for something. 

Another shiver ran down your sides making him tighten his grip on your hip, but his eyes never deviated from your face. You weren't sure of what he was waiting on, but you simply thought that maybe he was allowing you to catch the breath you asked for as you continued to run your fingers against his scales since he didn't show any signs of discomfort towards your touch.

He watches you as you turn your head to the side when the splashing sound of another fish capturing its prey gets your attention, his eyes darting towards your chest when you take a deep breath when you turn towards him again, finally getting what he was waiting for when he hears the sound of your teeth gently tapping against each other as you exhale, his fins twitching at a fast pace as he gets closer to you whilst his claws drop the golden medallion to tangle with the hairs at your nape again, cradling your face in his webbed hand.

“You’re cold”, he worriedly states while studying your face as you stare at him shocked, his words catching you off guard before you can actually register them, only nodding back at him as you feel another chill run down your skin. Noticing the action as you feel him gently grip your side before trailing his hand towards your elbow and down your hand, holding it in his as he pauses to glance down at it, caressing the back of your hand gently with his clawed thumb as his head slowly tilts to the side, enthralled with the smoothness of your skin compared the rough scaled texture he’s used to seeing. His eyes meet yours again as his other hand untangles from your nape and trails down your arm, now holding both hands in his whilst his digits continue to caress the back of them. 

“Get in the water with me”, he says while slowly pulling you back with him. 

“I cant”, you repelled.

“Why not?”, he asks as you watch his lips slightly turn into a pout while his fins seem to lower before flipping back up slowly making you press your lips together to hold back a smile, reminding you of a small puppy.

“I can't leave the boat and risk it drifting away”, you explain as he stares at you, hands still grasped together as you feel his thumbs stop caressing the back of your hands, causing you to look down at them briefly before meeting his gaze again. Vermillion irises studying yours before glancing around the inside of the boat, noticing the ruffled fabric of your clothes peeking behind you and fixating on your legs again. Watching how they slightly clench with each shiver before trailing up your abdomen to settle on your chest, his mouth flooding again at the sight, already feeling his tongue ache and his lips twitch to be wrapped around your nipples again. 

He didn't understand why the boat was so important to you since to him you wouldn't have a need to use it again, not after you've presented yourself to him and in his territory nonetheless, but he thought that if he was going to prove to you that he was a worthy mate, then he needed to cherish the same things that were important to you. 

Giving your hands a final squeeze before backing away into the water, he submerged himself as you quickly leaned over the edge of the boat to see where he was going, confused at the sudden change. Only catching a glimpse of his tail disappearing under the boat before you feel it move, going at a much quicker speed than the one you had when paddling by yourself, making you clutch onto the edge.

The cold breeze felt painful against your skin, making you curl into yourself as you wonder where he could be taking you, only able to see the few feet ahead of you illuminated by the moon and the splashing against the boat that activates the blue hues of the water. Closing your eyes when the force of his swimming became too much for your eyes to bear. Only opening them when the harshness of the wind no longer nipped at your skin and your ears filled with what sounded like tides rocking against the shore. To which you were correct, as you neared a small island a few feet away that seemed to be deserted from the lack of illumination, where only the shadows of the large palm trees along the coast were visible against the dark mass of fauna behind them. 

Bakugou pushed you as close to the shore as he could without risking getting stuck in the sand before waiting for you as he watched while you pulled your boat into land and secured it before entering the water with him, blue hues forming with each of your steps. Webbed hands immediately reaching for you as they trailed down your sides and onto your thighs, guiding them to wrap around his scaled waist. Gently caressing your skin as he swims around the coast towards the large rocks in the distance while staring at you when your hands reach up to touch his fins. The delicate skin felt soft against your fingertips in contrast to the scales on his body, the faint sound of low purring returning the more you massaged them as the sound blended in with the soothing crash of the waves against the sand.

“Do you trust me?”, he asked when you reached where the rocks began to disappear below the water. 

After a brief pause, you nodded in response. Even though you were still uncertain if you could truly trust him, given the circumstances he hadn't shown any deceitful signs to make him unworthy of your trust. 

He smiled softly at your approval before running his claws up your shoulder and cradling the side of your face in his webbed hand. A wet thumb caressing your temple as he gently pulled you closer whilst leaning in to meet you halfway in a kiss. In contrast to his previous ones, searing and hungry, this one was completely different. Delicate but devout as if he was trying to achieve something with it, feeling a low vibration rush through your body the longer your lips intertwined with his before pulling away with a small whine, already missing the feel of his lips against yours. 

“Now you're ready.”

“Ready for wh-”, you were cut short by him suddenly diving into the water at a great speed while holding you tightly against him. Eyes widening in terror causing panic to surge through your body as you try your best to hold in your breath while squirming in search of a release to swim back up to the surface. But to no avail, Bakugou keeps taking you both deeper and deeper along the wall of rocks before entering a small cave hidden behind some algae. Beginning to feel lightheaded from the lack of oxygen as your body forces you to take in a gulp of air that causes you to panic further when you breathe in the salty water. But to your surprise the water feels like it disappears as soon as it enters your lungs and is replaced with air. The realization makes you stop your thrashing as the panic is now overtaken by confusion. Your mind ran wild with all sorts of questions until your eyes met Bakugou’s, a grin adorning his features as it became clear to you what was happening. The kiss must've been dosed with some of the power that his kind possessed and that's why it felt like your skin was vibrating when it happened.

As the nerves in your body began to die down, you took the opportunity to look around your surroundings, only to feel your breath get stuck in your throat again at the sight. The cave was blooming with life as all sorts of underwater life swan around you. Coral reefs scattered all around the area with a vibrancy of colors and a variety of formations that you couldn't begin to wrap your head around. Orange and yellow tubes standing out from between the algaes as the reef shifted to blue and violet corals that took a more circular shape as different plants danced around them. Fish of all sizes swam along the reef as they didn't seem to pay you much mind, too distracted with finding smaller prey hidden between the long algae. 

Bakugou smiled as he watched you take in your surroundings in awe, glad that the hard work that he had put into his home throughout the years for this exact moment that he'd get to bring his mate home had been worth it. Leading you towards a trail that seemed to be lit up by underwater crystals that shined a beautiful celeste color towards another cave entrance. Guiding you through the abundance of crystals and corals before reaching a clearing further in where the water pooled and you could breathe above the surface again. The cave felt oddly warm despite being hidden under the ocean and the crystals expanded all the way up to the ceiling, illuminating the entire area with long descending vines that possessed flowers that also shined bright, their reflection dancing against the water. The floor was decorated with soft moss and rare flowers you've never seen before that expelled a rich aroma you could smell even from far away.

Bakugou swam to the edge of the mossy floor before hoisting himself up onto the ledge with you in his arms. Sliding further into the clearing until his tail was completely out of the water as he settled down with his head against a pillowy sponge, shifting his body to lay you down next to him. Taking a moment to peer down at you while you sneaked a glance at his tale, now able to see it in all its glory as your eyes fixate on it. The iridescent pale orange turning a darker shade that matched the fins on the sides of his face now that it was out of the water and the humid air of the cave was flowing through his scales. Feeling his chest swell up with pride the more you observed his tail as he started to slowly flick it up and down for the light from the crystals to glide across to show you more of its beauty.

Only getting pulled away from your fixation when you felt cold claws hook along the underside of the chain of your necklace before picking on the medallion again. The golden coin catching the merman’s attention again as he drags his thumb against the foreign markings around the edge of it. 

“Where did you get this?”, he asked as he forced his eyes away from the dark eyes of the golden skull at its center to look at yours, noticing the small red lines forming on the whites of them from the salt water as he listened while you explained the story of how the medallion came into your possession. 

“Sounds to me like that old man only gave it to you because he already had his fill from it and wouldn't be needing the medallion for a while”, he argued as you watched a scowl form on his face when he peered down at the necklace again. 

“What do you mean by that?”, you asked as curiosity builds up inside of you again. To you, this medallion was just money pirates chased in order to fill their pockets with riches that didn't belong to them and waste it all on cheap ale and pay for a stay at a brothel to use women as they pleased after a long cold journey through sea. But Bakugou’s tone indicated there was something more to it than that.

“This medallion belonged to my people many moon cycles ago… it was originally used to lure merfolk to its host signifying that our mate was near”, you listened intently as he continued explaining the story behind the medallion, watching as his throat bulged and his brows frown deeper the more he talked as if he was holding back on his emotions. 

“But after pirates found out of this, they've been stealing them and using them to capture merfolk to force them to use our magic and exploit it for their own greedy desires, which is how I sensed you near my territory earlier and went to make sure those disgusting bastards were not browsing it freely”

It all made sense now as to how he found you so easily when you were in the middle of nowhere, the medallion had given your location away to him and he set out in pursuit of the intruders sailing through his waters, but must've been confused when he found you. Looking the total opposite from all the pirates he had encountered, for they were brash and smelly when you were sweet and had an aroma unlike any other that he'd ever had the fortune of smelling. Which is why instead of casting the raging tempest he had originally planned for whatever misfortunate soul had stepped into his territory, he decided to investigate you further as he was immediately enamored with your rare beauty. Something ironic for the merman, for it was usually supposed to be the other way around. But nonetheless, he was glad he didn't end your journey, because for the first time in all his lonely springs he was hopeful that fate had taken its rightful course and put you on his path, destined to meet after watching so many of his kind lose their lives on false hope and getting captured, never to be seen again. Hopeful that he had finally found his mate.

And with the way you were looking at him, he couldn't help but to believe it. Your eyes expressed warmth and love, when others had expressed disgust and mischief. This wasn't Bakugou's first close encounter with humans, he had been captured by pirates before and has the scars to prove it where their awful nets had burned his skin. But his powers were no match for those bastards, strong enough to challenge Triton, the god of the sea, if he so pleased. But war was never in his interests, for the merman only desired to find his mate and spend the rest of his days with them in the beautiful and majestic home he has worked so hard to build over the years.

Webbed fingers ran up against your arm before cradling your face in his palm, claws massaging your scalp before gently pulling you into a kiss, this one much more tender than the one on the boat as you felt yourself melt against him. Trailing your fingers against the patches of scales on his strong arm until settling on his shoulder just below his gills. A soft purring returned to his chest when he felt you deepen the kiss as you found yourself craving more of him and the same passion and overwhelming pleasure he gave you on the boat. 

Longing to feel the same bliss you experienced before, as you finally understood what all the maidens meant when you would stumble upon them talking about their intimate encounters with their partners and you couldn't help but to overhear, thinking it would help to prepare you for when your time came. And the more Bakugou delved into your mouth with his tongue, the more your body reacted to him as you felt your arousal begin to drip against your inner thighs. Although you couldn't stop but wonder how this would work with the differences of your bodies.

“Bakugou?”, you whisper as your hand slides from his shoulder down to rest against his chest while pulling back to meet his eyes. “How exactly do we um-...?”

The merman hummed before leaning in to pull you into another kiss. “Don't worry, I'll guide you.” 

Taking your hand on his chest in his webbed one as he guides it down his abdomen over smooth tangerine scales to settle just below his waist. His hand slightly pressing down on yours as your palm rubbed against the scales, feeling the change in texture when the scales shift under your touch. The rumbling emitting from his chest encouraged you as your hand began to move on its own without the merman’s guidance, causing his head to tilt back with a low groan the more you explored the slight dip beneath his scales. Watching how they slowly moved against your hand until a slit formed on his tail, running your fingertips along the edges as slick began to gather along the opening.

Your eyes flickering towards Bakugou’s face, head thrown back and eyes tightly shut making you bite your lip when you venture your fingers further whilst watching his reaction as you run them along the center of his slit, gathering some of his arousal before slowly inserting two fingers inside. Wet warmth immediately engulfed your digits the more you push them in as your thighs twitch from the breathless moans that escapes the merman’s mouth. 

Slowly pulling your fingers out to the first knuckle before pressing them back in as you started to thrust them in and out of the slick hole. Your arousal now pooling beneath you as your cunt clenched around nothing with every soft gasp and whine he made with each of your movements. A whine escaping your own lips when the merman leaned down against your ear and ran his tongue along it, occasionally sucking on your lobe as the slight scrape from his sharp teeth against your skin left you gasping softly as well. Turning your face towards him as your lips immediately linked, sloppily kissing each other as his tongue tasted every part of your mouth before slowly sinking down your throat as drool began to slip past your lips and drip down your chins, making your eyes roll behind your closed lids at the filthy act. 

Pulling the salty muscle out after wallowing in the feel of your throat tightening around him with each gag. Loving the sight of you panting before him as he runs his tongue across your spit-covered collarbones while you catch your breath, never stopping the thrusting in his slit as you begin to feel something hard rub against your digits. The slick becoming more viscous as wet sounds mixed in with your cries and gasps.

Curiosity creeps at you as you scoot down, laying kisses along his muscular chest and abdomen before settling in front of his slit. Pressing quick pecs around it as you feel the merman tremble against your touch, webbed hands reaching for you as they caress the side of your face. Slowly pulling your fingers out as you scissor them to examine the thick slick coating them as sticky strands form between your digits. Bringing them towards you as you give an experimental swipe of your tongue, lashes fluttering at the salty taste before popping them inside your mouth to suck them clean. 

Bakugou’s watchful eyes never leaving yours as his breath hitches in his throat when you lower yourself and give his slit one broad stroke with your tongue. A much louder purring emitting from his chest with each swipe before a yelp bursts from him when you dipped your tongue inside his slit. Slick gushing from it as you tried your best to swallow it all down eagerly while your fingers massaged along the scales around the entrance. 

Stimulating the area until you felt something hard poke the tip of your tongue as you lean back to press your fingers around the slit, feeling how the scales continued to shift again while you watched as something began to emerge from it whilst the merman thrashed under your touch, hearing how the fins at the end of his tail rapidly flapped against the mossy floor and the ones behind his ears flickered.

The merman's cock was an intense shade of red, long and thick with a smooth tapered tip and small ridges along the sides leading towards a pulsing knot just at the base of it. The small hole on the pointed tip leaking a white liquid equally as viscous as the one gathered around his slit, that dripped down on the sparse scales matching those on his body that adorned the bottom of his shaft as it twitched in front of you. Making you lick your lips as you feel yourself salivating at the sight. 

Ignoring how Bakugou opened his mouth to speak but the words trailed off into a moan when you lunged forward to run your tongue along the scales beneath his cock as you shifted your head from side to side to lick around his length, tongue getting caught on each of his ridges. The feel of them causing a shiver to run down your spine as you wondered how they would feel moving inside you before wrapping your lips around the tip, flicking your tongue against it as you lap up his thick release directly from the source. Taking his length in your mouth the best you could, cock too wide to fit completely inside as you wrap your fist around the rest and start pumping it slowly.  

Your other hand nestled between your wet thighs in an attempt to relieve the overwhelming tension on your cunt but to no avail, you needed more - craved more. And Bakugou could tell, desperate for more as well as his knot felt hotter than ever, aching to be buried inside you.

The claws that were gently cradling your face, now dangerously gripping your nape as they urge you forward. Lifting your head from his cock with a wet slurp while strands of slick stretch from your lips to his tip as they cling to your chest when you move further to straddle him. Legs stretching wide from his ample tail as his claws travel down your body until reaching your waist to grope the fat on your hips. 

Guiding you to sit against his throbbing cock as he urges you back and forth to grind your slick pussy against him. The feeling of his scales and ridges rubbing against your cunt makes you shiver while his tip leaks more and more with each motion. Lustful eyes staring down at how your lips part around his thick shaft, his tip nudging your sensitive clit smearing thick arousal against it as it mixes with yours causing wet noises to fill your ears the more you grind on him, gradually picking up the pace until you feel your thighs shake with the need to release, the hard knot at the base of his cock growing bigger as it stretches your lips further, the thought of it inside of you being the final push you needed as you gush all over his cock.

Your warm fluids against the merman’s scales drive him insane as they seep into his slit, the knowledge of you marking him with your essence turns him feral, urging him on with the desperate need to bury his cock inside of you and claim you the way you did him. The way only a mate can.

And he does. Flipping you both over as he rests his strong scaled arms on either side of your head, caging you beneath him while pressing his large cock against your cunt, grinding on you like before with more vigor. His cock leaves a trail of arousal along your abdomen with each yerk of his tail as it starts to pool in your belly button and trail down your mound as the wet noises resume. Your legs parting wider to accommodate his size when your abdomen twists with pleasure, craving to be plugged full of him as your eyes water with how good his ridged cock feels against your needy pussy. 

“Bakugou - ahh - please, put it in”, you whimper as your hands reach for him. 

“Thought you'd never ask”, he rasps, warm breath hitting your skin as he leans down to capture your lips. Dragging his tip down your folds to your entrance, teasing it before pressing forward, slowly entering while your tight walls clench around him. The stretch makes you whimper into the kiss as his tongue ventures inside your mouth, tasting every inch of you as it travels further in, swallowing your cries.

His length gradually pushes into you until his knot is pressed against you, your cunt not quite ready to take its size yet as he slowly starts to pull out, the feel of his scales shifting inside sends shivers up your spine, making you moan around his tongue, tears spilling from your eyes from the overwhelming pleasure. His hips stop when only his tapered tip remains inside you before thrusting back in, this time a little quicker than before as the slick from your bodies makes it easier for him to slip right in. 

Drool drips from his mouth to yours as it dribbles past your lips and down your cheeks. The purring from his chest now mixing with his whimpers while the tips of his fins vibrate from the new sensations. Your pussy unlike anything he's ever felt before, tight and hot - so incredibly hot he feels he mind burst from just being inside of you, so used to the cold touch of the sea to aid him during mating season when all he had were his webbed fists. Gummy walls gripping his cock with each thrust as he increases his pace while clawed fingers guide your legs to return to his scaled waist as you wrap them around him.

Pulling his tongue out of your mouth to allow you to catch your breath as the sound of your cries fills the space. Leaning back to watch how your pussy swallows him, his length glistening with your cream as it rings above his knot, so wet and willing for him as he slows down his thrust to press his knot against you, both of you watching as your cunt starts to take it past the top, the stretch feeling so impossibly good and it's not even half way in. Slowly working your cunt around it as he salivates at the sight of your pretty pussy sucking him in - so tender and needy - gripping him tighter every time he pulls back as if begging to be kept nice and full, and who is he to deny you of such needs.

The feel of you is way too good, he might be addicted. The thought of keeping you plugged with his cock and fill you with load after load of his thick cum while his scales soak in your fluids ignites the carnal desire to finally make you his mate as he thrusts the remaining inches of his knot inside. Reveling in the hot, pulsating heaven that engulfs him whole as he groans at the feel of his scales getting soaked by a deliciously warm liquid. Watching as a stream of clear liquid gushes on him from your pussy while you arch up into him, flushed skin and glossy eyes staring up at him as a melody of whimpers flows past your panting lips and he thinks he's never seen a sight more beautiful. 

Pearly spikes flashing at you between his spit-stained lips as he smiles down at you, clawed hands traveling up your body, cupping your tits as they pinch and pull of your nipples causing you to release a whine before cradling your head by your neck, cold thumbs caressing your temples while sharp nails tangle with the damp hair at your nape. Leaning down to pull you into a kiss, slow and succulent, causing you to melt further into him as your stomach jumps with emotions. Hissing when those sharp canines nick at your bottom lip as the metallic taste of your blood fills your mouth. The merman takes a deep inhale when he gets a taste of it as well, eyes rolling behind closed lids as he swipes his tongue against the cut before parting from your lips. Watching as his eyes remain close, savoring your taste as his throat bulges, swallowing down the river of saliva that pools in his mouth.

A hint of fear pricking beneath your skin when he opens his eyes again, darkened irises staring back into yours, like a predator about to devour his prey - carnal and hungry - and you fear he'll swallow you whole, but a part of you might crave exactly that as you feel the pulsing on your clit grow needier. Your pussy clenching around his thick knot gives you away causing a devilish grin to spread across his features again as he slowly pulls his knot out of you before pushing it back in, molding you to his size as he starts to thrust in and out of you with ease the more your pussy sucks him in. 

Setting a steady pace while his arms travel towards your hands, capturing them in his to pin them above your head before leaning down to swipe his tongue on your bottom lip again. The wet muscle exploring down your chin to the center of your throat, his teeth dangerously ghosting above your skin causing goosebumps to burst on your skin at the threat. Feeling how the cold tip of his nose caresses the area before trailing to the side of your neck, lingering on the juncture of your shoulder as he takes a deep inhale against your skin followed by a deep thrust that keeps him buried inside you all the way to the base of cock before resuming his pace when he moves up to your ear. Sucking on your earlobe as you feel the tip of his tongue flick against it inside his mouth before pulling back and settling back down the juncture where your neck meets your shoulder.

The purring in his chest shifting into what could almost sound like hungry growling as the need to make you completely his overtakes him. The teeth that sink into your neck pull a scream from your throat as he plunges his cock forward, creamy ropes of cum spilling inside of you, filling you up with a hot load that pulls another orgasm out of you as your pussy clings to the knot pulsing against your gummy walls while you gush all over his scales. The flow of blood traveling into his mouth sends him into bliss as it urges him to spill more of his seed into you, certain to breed you with his litter from the copious amount that is now dribbling down your rear and pooling beneath you to be absorbed by the mossy floor. 

By the time his knot stops pulsing, you're both left a sweaty and panting mess. His fangs retreating from your neck as blood drips from the puncture to which he dives back in to swipe his tongue against it to clean it before meeting your gaze again. Noticing how his eyes have returned to the love-filled ones that first brought you here while his hands release yours to gently brush the stray hairs clinging to your damp forehead before leaning down to capture your lips again in an even gentler kiss, the taste of your blood still lingering in his mouth while he shifts his weight so that you could lay on top of him, while you wait for the knot inside of you to swell down. 

Soft touches and loving gazes as he tends to you, making sure your comfortable and taken care off as he wiggles his tail to sink against the moss, creating a bed for the both of you to rest makes you realize how thinking back on it, it was an insult to compare this to that of the maiden's encounters, for those were thoughtless with the purpose of creating more heirs to their husbands family names and earn them more obliging political images, but this was filled with love and attention that only a true lover could provide.

And although you weren't certain where your future would lie alongside the merman, you felt oddly at peace after so many years of chasing after dreams or expectations that could never fulfill your needs quite like he can as you settle against his chest, gentle claws rubbing circles against your back as the soft purring from his chest lures you to sleep. 

“Rest, my mate”, you hear the faint whisper of his voice against your hair as you smile to yourself, making the mental note to thank Captain Aizawa for the medallion regardless of his intentions if destiny ever were to set him back on your path.

Pairings: King Merman! Bakugou x Human! Fem! Reader

Word Count: 5.2k

Warnings: Just fluff.

Summary: You meet a merman one day and find yourself with your very own trading companion. You exchange gifts of the land and sea. The two of you were fine until Katsuki says he wants more from you.

𝐅𝐈𝐂 𝐌𝐀𝐒𝐓𝐄𝐑𝐋𝐈𝐒𝐓

Katsuki Bakugou gets everything he wants. The underwater kingdom is his, and whenever he wants or needs something, with a flick of his webbed hands, it appears. He is worshipped and maybe even feared by all of the seas. King Bakugou, the warrior ruler of the sea.

Except for a mate. No matter how many mers, both male and female, his court presents him with, he never feels anything toward them. His mother scolds him for not even meeting the young candidates, but he doesn’t give a shit. He gets what he wants; he will know if they are worthy just by a single glance.

So on some days, he forces his mother to watch the throne while he swims and swims just to clear his mind. He picks fights here and there with other sea creatures just to test his strengths. After he wins his battle against his third great white, he realizes he needs something stronger. Something to really pique his interest.

A human. Well, from afar, they look pathetic with their gangly limbs, but it is common knowledge to a mer that they possess weapons that can easily kill any creature of the sea. But this is Katsuki Bakugou we are talking about here. He isnt just some mer. He is the most powerful being of the sea. No one, including a human, could beat him. 

So, the arrogant bastard took toward the surface to find the closest human. The water becomes more shallow, and not that he would ever admit it, but adrenaline fills his veins when he gets closer and closer to the shore. 

Luckily for him though, a human was close. In the water, too. He was dreading trying to coax one into the ocean. Katsuki snickers at the strange limbs called legs kicking to try to keep the human afloat. It was so embarrassing for them. One flap of his tail, and he is yards ahead of them. It was incomparable the strength between the two species. 

Without much hesitation, he grabs the submerged legs and pulls. They scream, of course, when they lose their precious oxygen and are surrounded completely by salt water. Their arms flail, and their legs continue to fight their way to the surface, but it’s all in vain. After all, this is Katsuki’s element.

Wanting to get one glance at the human before making a swift and easy death, he turns the figure around, and his eyes widen.

You were pretty. Prettier than any of the other mers he has ever seen. Even if your face is contorted in fear, he takes a second to admire your hair, eyes, and lips. They were all so cute. Exactly the way he likes them.

And your strength was actually impressive. Although you were no match for the king, you were definitely putting up some sort of a fight. He actually had to grip you tighter so you wouldn’t squirm away. Both of you knew it was a losing battle, but still, you really tried. You definitely had survival instincts.

As Katsuki gets distracted admiring the creature, you get one lucky hit and manage to kick him right in the nose. He hisses out and lets you go. 

He could go out and grab you again easily but didn’t feel the need to. After that fight you put up, you deserved to stay alive. Stay alive, so Katsuki can meet you again.

You were just trying to take a dip in the ocean, really. After all the stress you have had this week, you deserved it. A nice relaxing day by the beach. You were not planning on almost getting drowned.

You swim swiftly toward the dock and yank yourself up before the creature tries to grab you again. You didn’t see much except for flashes of blonde hair, red eyes, and an orange tail. What was that thing? Some sort of fish? It just didn’t make sense. What fish could pull you down into the water? The beach was completely private, so it’s not like you could tell a lifeguard what happened.

You shiver and grab your towel before heading inside your beach house. You began to ponder, desperately trying to figure out what the strange animal was. After about an hour of research, you came to the decision that it was definitely a mermaid. Many studies have shown that they do, in fact, exist but are extremely rare to find.

It seems absolutely insane to you, but what else could be able to hold onto you like that? And that tail…It was huge. 

You aren’t going to go near the beach for a while. Even so, though, you really did want another glance…I mean, seeing a real-life mermaid is crazy! Once little peep of the mermaid surely wouldn’t be a problem.

After all, curiosity killed the cat, but satisfaction brought it back.

Three weeks. Katsuki has managed to escape his royal duties to see your ass, and not once have you come back even close to the water. He has scouted the area over thirty times and found the small shack you call home. The mer lets out a scoff as he watches your shadow move back and forth inside the building.

He has thought about throwing something at the building but thought against it. He didn’t want you to think he was a violent maniac (even if he was) with your first real meeting. So, he boredly swam back and forth, waiting for you to come outside again.

He was in luck because at around 5 pm, you did finally open the door of your shitty shack and step outside. He quickly dove into the water to watch from below the surface. The last thing that he needed was to scare you back into hiding. 

His eyes follow your figure as you walk toward and onto the dock that bridges into the ocean. You look nervous but determined, and Katsuki can see you holding something but can’t determine what it is. 

Suddenly, your loud voice calls, “Hello!” over and into the water. You flush in embarrassment for doing something so silly. But you continue anyways, “If you are out there, mermaid, come over here!” It probably wasn’t the most convincing way to lead the visitor over, but whatever, you were desperate.

Katsuki smirks in triumph. He only knows very little of the human language due to his studies as a child. All he knows is that you greeted him and said the word “mer,” so you must be calling for him.

So he pops his head out of the water with a small smirk on his face. His orange ear fins are spread wide and on display. His scarred tail, from all the fights he has won, beats against the water as he watches you. He gently displays his sharp canines with his smirk. Like always, he looks like the strongest being of the sea. 

When you take in his appearance, you scream and fall onto your butt.

Katsuki lets out a light bark in laughter, watching you fall. He couldn’t blame you; those strange limbs looked hard to use. If he were human, he definitely wouldn’t struggle, but he bets Denki or Eijiro would. 

He puffs out his chest and made himself look as large and powerful as he could in the water. “Hello, I am King Explosion Murder or King Bakugou, ruler of the undersea.” He stood there waiting for the excitement or shock that usually comes from hearing his title, but nothing came. “Ruler of the undersea. Did you not hear me extra?” Judging from your frightened appearance, trembling on the doc, no, you did not understand. 

And then he remembered. Of course, you don’t understand. He isn’t speaking in your tongue. To you, it must have sounded like a bunch of trills and clicks.

Katsuki opens his mouth to speak but growls. He doesn’t remember how to speak your language. It’s unnatural for mers to do it, but nobility are taught it, just in case. However, that was when he was ten, and he hasn’t practiced since.

Upon hearing his frustrated growl, you point your knife straight at him and threaten him. “S-Stay back! I have a knife, and I know how to use it!” You didn’t, but that was beside the point. You shouldn’t have come out here. It was a stupid idea. Curiosity did kill the cat, and you’ll need more than satisfaction to get you out of this situation.

The blonde doesn’t understand any of your words. The only thing he understands is that you are holding out a knife toward him. A gift! Already? Katsuki is known to be bold, but here you are, offering a courting gift on day one. I mean, it made sense, considering his physique. You must have seen how powerful he is and were quick to pounce. Eager, he likes it, and he can’t really blame you.

He huffs out pride and lets out a click in thank you. Then, quicker than lightning, the blonde snatches the knife from your hands and into his. He holds it up to admire it, unaware that you’re currently freaking out without your weapon to defend yourself. He scoffs at it. It was sharp but not even close to his very own canines. He turns toward you and pulls the knife up next to his teeth to show the comparison. He is once again unaware of how you pale drastically.

“Stay.” He uselessly commands before diving down back into the water, knife still in hand. You cock your head to the side in confusion at his disappearance, but realizing this is your only time to escape, you begin to book it down the dock and toward your home. 

You don’t get very far. Katsuki, effortlessly fast, grabs your foot before you can return to the sand. You stumble forward and land on your knees, causing you to hiss in pain. A small scrape forms on your left knee.

He huffs in annoyance. “I said stay, you idiot! Look what you did!” 

The loud growls cause you to tear up. This is it, isn’t it? He has got to be growling so much  because his prey got away. It was a stupid idea, all of it. You were going to die, and nobody was going to find your body and–

Katsuki grabs your leg and licks the wound on your knee like he has done countless times with others during battles. After all, mer saliva has healing properties. Then as your eyes widen in shock, Katsuki pushes an orange sea shell toward you. He set in the water, just earlier for you. He lets out an annoyed bark when you don’t reach for it, and hearing the warning, you quickly scramble to take it. The blonde smirks in triumph and continues back to healing you.

You shiver when you feel the tongue back on your knee. It was like a cat’s tongue. The prickles gently nick at you. But, with all the courage you can muster, you tear your gaze away from the creature and onto the sea shell. It was light orange, and absolutely massive. Seriously, it was about the size of your whole hand. But, it was pretty and shiny in the sunlight. 

You spare a glance at the blond, who is still completely focused on the task at hand. You could guess that he is trying to heal you for some odd reason. It made your heartbeat begin to return back to normal. Why would he heal his prey from such a minor wound if he was going to kill anyways? But why would he want you alive?

Then, you look to the right of him and see that in his hand, he is still holding the knife. Your eyes widen in realization of what is happening. “Trade! You want to exchange items with me. From the…human world?” The mer tears his mouth away from your skin and furrows his eyebrows in confusion. You point to the knife and then the seashell. “Trade?” You explain.

Katsukis eyes widen in understatement. So, the human word for “courting” is “trade”! Only a genius like himself would be able to figure that out so quickly. He lets out a soft grumble and nods his head. Then, realizing if this relationship is going to work, Katsuki has to tries to try and speak in your tongue. “Chr–aye-dd”

Your mouth falls open at the attempt of your language. The whole thing was absolutely insane, and now the strange creature is trying to communicate with you. This is a once-in-a-lifetime experience, so you continue speaking. “Yes, Trade! But say “Trr” instead of “Chr” You enunciate the sounds, so he understands.

Katsuki grumbles stubbornly when you correct him. Only his mother has been one to nag in, nobody else has the guts to do it, but here you are correcting him within the first greetings. You were bold; he had to give it to you. He also likes that. So, for your sake, he tries again.“Trrr-aye-d”

You laugh at this and smile gently. “Yes! Thats it! Trade.” You once again point to the knife and the seashell. 

Seeing you smile, Katsuki lets out a trill and nods. Without much permission, the blonde rests his head on your leg, careful not to touch the wound. Then the hopeless mer begins to daydream. This was going perfectly! Not even one day of knowing him, and you have already allowed him to court you. Now, it was smooth sailing from here. He just needs to bring you a couple more gifts, and finally, King Bakugou will have his very own mate! 

You, on the other hand, are freaking out a little bit. A merman is here and resting his head on your legs! Nobody would ever believe this was happening. 

You tear your gaze away from him for a second and notice that the sun is almost down. Although the mer seems friendly as of now, you didn’t feel comfortable with him enough to stay with him during the dark. So, you try to gently get it up without disturbing him too much.

His daydream comes to an abrupt stop when you begin to move your legs. He groans in annoyance. “Stop.” He commands, which comes out in a small bark. You ignore him, considering you can’t understand him, and Katsuki slides back into the water. 

He lets out a low growl, and your eyes widen. He wasn’t having second thoughts about this little exchange, right? So as you get to your feet, you quickly say, “Tomorrow, I will come back, and we can trade again. Okay?”

Katsuki looks scepitical. He only got out the word tomorrow and trade. Which definitely is a good sign, but does he trust you enough to keep your word? If he has to wait another three weeks, he is going to absolutely pissed. But then again, you seem to like him a lot if you already began wanting to court him on the first day of the meeting. Plus, you allowed him to touch you, once again, another good sign. You have got to like him.

So he sighs and trills a goodbye before swimming back down into the deep blue sea.

Katsuki Bakugou was adorable. It’s been about a week since you have known him and you have visited him every morning. He seems to be rather attached to you already. One day, you overslept and missed his meeting, and the next day you got an earful of mostly growls and barks. You thought it was adorable that your new friend missed you.

Currently, it was Friday, and exactly a week since you guys have been talking to one another. You learned his name and even have gotten him to speak in small sentences. He seems to pick up the human language very quickly. You wonder if it was a mer thing or a Katsuki thing.  Either way, you praise him immensely, and he acts like he doesn’t care, but its obvious by the red ting on his cheeks he does. He also teaches you the language of merfolk. Your vocal cords don’t really do the barks or clicks justice, so the two of you continue to speak in your language.

Not only that, but the mer was heavily physically affectionate. It was hilarious, considering the fact that he would insult you on being a “weak human,” and then the next minute, would curl into your lap as if nothing had happened. 

In all honesty, no matter how much of a brat the mer was, it has been one of the best weeks of your life.

“Human. Att–tention. Now.” The orange merman demands when you stop running your fingers through his soft blonde hair and stare off into the distance. You chuckle at this and continue to pet him. You are glad you taught him the word “attention” because before that when he needed it, he would take to softly biting you. You have small bite marks all over your leg because of the overgrown, needy creature.

A small, content smile falls on his face as he nuzzles into your legs. Courting has gone absolutely perfectly. You were gentle and warm but were able to put up with his shit. A perfect match the two of you are. 

Of course, every once in a while, you do say some stupid things. “Katsuki, do you think I can meet some of your mer friends?” The merman looks up at you and gives you a familiar glare. You smile in return, hoping to encourage him. 

It doesn’t seem to work because he lets out a cat-like yawn and closes his eyes again. “Friends, weak. Stupid,” He grumbles, and you roll your eyes.

“I bet we would get along considering you call me weak and stupid,” You remind, and Katsuki opens his eyes back again to glare at you.

He lets out a series of trills and clicks on accident before sighing and switching back to your language. “On–ly need me,” He challenges, and you give up the argument. Katsuki was as stubborn as a mule. If he didn’t want you to meet his friends, you won’t.

All of the sudden, Katsuki rolls off your legs and into the water. You tilt your head to the side, but the mer just grumbles out a, “stay.” and lightly bites your calf to get his point across. You, like always, flinch at the bite, but let him, knowing that denying him makes him even more upset. Besides, it’s probably a sign of affection.

Then, he dives back into the water, leaving you alone. A couple of minutes go by, and eventually, he pops his head back above the water. He raises his webbed hand and shows a squirming fish in his hands. You give him a questioning stare, but before you can ask, he plunges his sharp canines into the body. The fish dies immediately, and you’re left in shock at what the hell just happened.

He then offers the fish to you. “Eat,” He barks, and you shake your head, disgusted by the fish placed so close to you. Katsuki doesn’t like this answer, and he glowers at you. “Food. Eat. Hun–ted for you.”

Even if you are used to his demands, you are not willing to go that far for the sea creature. “That will make me sick, Kats. I can’t eat raw fish, but I really appreciate the offer.” Katsuki stares at you for a second and then, like usual, lets out a series of annoyed trills. He grabs the fish and quickly begins devouring it, bones and all, much to your horror. 

Once finishes, he looks back up at you with a satisfied smirk. “Good Hun–ter.”

You nod in agreement, “Yes, you are a fantastic hunter Katsuki, way better than me.” He chirps and nods, preening at the statement. You roll your eyes and laugh at his behavior. 

And then he sighs and, like usual, begins his goodbyes. He seems to be a very busy creature, only being able to meet for about two hours a day. You wonder what is taking up his time. Another mer? Maybe he has a family? But he never mentioned either of these things.

You don’t get time to ponder on it, because Katsuki rubs against your legs one last time before saying his usual statement. “Trade. To–mor–ow”. To which you nod and wave your goodbye with your new pink seashell that you add to your collection.

He nods before falling under the water and disappearing.

You begin to think more and more about Katsuki. Even if he was another species, you couldn’t help but be attracted to him. His muscular upper body, his soft blond hair, his piercing red eyes, and even if you hated the canines in the beginning, they are beginning to grow on you. Plus, he has the best personality. Although it is a little aggressive at some points, you know he has good intentions. 

He is sweet to you, under all of the insults, and is exactly your type (well, if he was human). So, like a normal person of your age, you begin to daydream what it would be like, to be more than a trading partner with the strange, but enthralling creature.

It’s been about three weeks, and the two of you have been “trading” almost every single day. Things like forks, coins, small mirrors, and cups have been given away while you receive an abundance of seashells and old jewelry that has fallen into the sea. Katsuki goes out of his way to find the nicest items he can. After all, he is a king, and his mate deserves only the best.

Katsuki knew he was doing a perfect job courting you. You are happy with him, he provides for you semi-well (only because you won’t take his food), and he is a fantastic protector. Often times the red-headed shark tried to talk to you, but Katsuki manages to scare his friend away every time. He isn’t going to risk you falling for some other extra. You were way too eager to court with him (even if it did make sense considering his physical appearance), and he didn’t want to play the odds of you accepting some idiots advances. You were his, and he was yours. That’s how things are supposed to go. So, today is the day he was going to ask you to be his mate. Then, the two of you are going live happily ever after.

He leaves his mother on the throne, like always, and grabs the ring he has planned to use. It was gold, and he removed the previous gemstone and replaced it with a pearl he had found when scouting the area for any threats. He knows that rings are weirdly important to humans, so, it was probably a good idea to get one. Then, he heads to your guys’ meeting spot.

You were waiting at the dock with your feet in the water. He swims up to you and lightly traces his hand up the bottom half of your leg. Then, like usual, he lays his head on your legs. You smile and pet his hair, “Hey, Katsuki.” He lets out a small click in greeting.

“I brought you something,” You continue, and Katsuki’s ruby eyes look up at you, slightly intrigued. You always gift him the strangest things. You pull out a tennis ball, and Katsuki squints at it before snatching it from your hands. He then begins to assess it. He rubs his cheek on it, then bites it gently, and finally growls at it, just to make sure it wasn’t anything dangerous. Once completely satisfied that it was safe, he trills in thanks. In your broken language, he says, “Good gift. M–Mine better.” to which you chuckle and nod, not willing to argue with the guy.

He pulls away from your legs and back into the water. A second goes by, and he is back up above the water and smirking as confident as ever. Katsuki quickly reminds himself of the stupid human customs he is trying to follow. He has practiced this sentence about a billion times. He forcefully, and a little nervously, thrusts the gold ring into your hold. “I K-King Katsuki Bakugou, take you, Y/N L/N to be” He lets out a small growl in frustration when he forgets how to pronounce the last part correctly. “To be…my mate.” He puffs his chest out while he waits for the tears and your acceptance.

But much to his surprise, you begin to giggle as you grab the pretty ring. You admire it and praise him on how beautiful it was. You have never seen a ring like this, it was pretty. You place it on your pointer finger and smile. Then you pat his head lightly and say, “Yes that is how wedding ceremonies go! How did you learn those lines? And I love the addition of “king.” Great touch Kats. Actually, did you know that I happen to be the Queen of the human lands?”

Katsuki has never been more confused in his life. Firstly, you put the ring on the wrong finger. He read so many slabs that told him that you were supposed to place it on the one next to the pinky! Secondly, you didn’t even respond to the declaration. You just praised him on his abilities. Thirdly, you are a queen?! Would this mean that your two people can finally live in peace? This seems like the most important question, so he says, “You–Queen?”

You laugh once again and, this time, shake your head. “No. Sorry I was just teasing you, Katsuki. I couldnt help it since you said you were the “king” of the sea.” He furrows his brows. Did you think he was joking? He has left his people abandoned for you daily, and you don’t even believe him!

“I am King! You are my Q-Queen! Mate!” His newly learned language gets choppy when upset. He grabs onto the doc with his hands and looks up at you with a scowl.

You tilt your head to the side. “Mate?” 

Poor Katsuki goes into another hissy fit. He growls and grumbles, and you furrow your eyebrows, used to his dramatics. You don’t know exactly what’s pissing him off, though. 

You are pissing him off. You guys have been “trading” for two weeks now, and you don’t even know what mates are. What do you think these entire interactions have been about? “We trade. Now we mate.”

“Like animals do?”

He uses his tail to propel him above the water. Now he is almost your height when you are sitting down on the dock. He only does this when he really needs your attention. The scowl has deepened, and this time, you do flinch. “Like mer do!”

Was Katsuki joking? About the king and the mating thing? You have never heard him joke before, but also, what was he talking about? You guys originally were trading items, and now you guys are friends. Did you confuse him somehow?

Your thoughts were suddenly cut off when Katsuki leans forward and pressed his lips onto yours. They are wet and a little salty, but still soft. You are just glad that you can’t taste fish on his lips. Your eyes widen for a second, but then gently kiss back for a second, and Katsuki pulls away. Red tints his face, and you probably match his furious blush. “S-See! Mate.”

Oh. So this entire time, he has been wanting to get with you? You use your hands to cover your face in embarrassment, but Katsuki is quick to remove them with a short but scolding bark. “We trade. Now we mate.” He repeats.

You realized that you confused him this entire time. He misunderstood your definition of trade. “You court and then mate. Not trade Katsuki. Trade is when you exchange items, like merchants do.” 

Katsukis face contorts into disgust. Like the lower-class people? He is a king, for christ’s sake! How did you think that he was trading with you like some lowly extra? He didn’t need your useless items (yes, he did, he actually loves them all)! He lets out a series of growls and barks in the mer language at your misunderstanding. Finally, he, in your tongue, says, “Stupid human!” 

Although you haven’t known Katsuki for that long, you know is not mad specifically at you, just upset. I mean rightfully so; you have misunderstood his attentions this entire time. You have got to make it up to him. So, you lean over and tilt his chin upward toward you and cut off his growls with a soft kiss. He, of course, shuts up and kisses you back intensely. 

He hates craning his neck to kiss you, it makes him feel small, and he is the strongest creature under the water; he should never feel small. So without much hesitation, he grabs onto your figure and pulls you into the water. 

You screech in surprise as the cold water hits you, and Katsuki grins. He presses his lips against yours again and effortlessly holds you above the water. Eventually, you pull away with a trail of salty saliva. “You are going to have to recourt me.”

Katsuki frowns as his face fins pin straight back on his face. “Why?” 

“Because I didnt know you were trying to courting me. I want to enjoy it this time,” You hum, and Katsuki flicks a tad bit of water into your face. You scrunch your face up and whine, and Katsuki laughs low.

His orange tail flicks into the water. “Idiot human.” But, he still nods in agreement. It wasn’t like he was going to force you to be his mate. If needed to be, he can wait.

Your smile turns mischievous. “And you have to court me like a human does.” This time Katsuki does growl in annoyance. Human ways are so tedious.

“No.”

“Awe I guess I just got to find a human “mate” to court me….” You fake pout, and Katsuki grips you tighter. He can see right through your bluff, but pissing you off right now in such a nice moment does not seem like the best idea.

“Fine.” You give him a peck on the lips for his compromise. He in return, grabs your hand and replaces moves the ring from your pointer onto your ring finger. He lets out a satisfied click with the new placement. Now both mer and human will know you are his.

As you watch Katsukis ministrations, you think back to what he said earlier and hum in thought. “Hmm and Kats you were just  joking about being a king right?”

Katsuki laughs mischievously and a little arrogantly. Your eyes widen at the response. “Right, Kats?”

“Nope.”

You squirm in his hold, but he wraps his tail around you, preventing you from leaving. “I can't be the ruler of a kingdom that I’m not even from! Plus I'm not even a mermaid!”

But Katsuki was already lost in thought, daydreaming once again of the future. Besides, there are many ways to get you changed into a mer, it wasn’t hard. “King and Queen Ex-plo-sion Murder. The most powerful mates of the sea.”

“Katsuki!”

+PART ONE+ (1/?)

To say you almost had a heart attack was an understatement.

You had been sitting on the dock at your stepfather's beachfront house, your legs dangling over the side and kicking at the water with your feet. What you hadn’t expected was the blonde hair that broke the surface, making you shriek in alarm before your heart calmed slightly...momentarily. At first, you’d wondered what the hell a...handsome young man was doing in the water near your stepfather's house. It was pretty secluded. To your knowledge, there wasn’t another home for a few miles. Did he swim from a nearby home? These questions initially entered your mind as his crimson eyes stared quietly into yours, your mind not processing how strange this was...at first.

Your lips parted to speak, his crimson eyes flashing in interest as his muscular shoulders broke the water the same time his...tail did. All the words died in your throat as you stared in disbelief, blinking rapidly as the brilliant orange and black tail lightly splashed out of the water behind him. It was gorgeous, iridescent and massive.

You couldn’t move – you were in too much shock at what the fuck you were looking at. His handsome head tilted down slightly, his crimson eyes bright and questioning. His sharp, yet handsome face looking just as intrigued by you as you were him – though, he admittedly didn’t look frightened of you. You weren’t sure what expression was on your face, but you highly doubted it looked much different than a deer caught in headlights. His crimson eyes moved down your body, his gaze lingering on your bare legs and feet that were under the water. He was a few feet from you, and when he slowly moved forward, the humongous black and orange tail moving behind him...you regained control of your body.

He was so big. He could pull you under, he could – you gasped and scrambled backwards out of the water, your eyes huge as he paused in his approach. His brows furrowed slightly, as though your behavior perplexed him. He was looking at you as though he’d never seen a person before...but there was zero fear. Then again, why would he be afraid of you? You weren’t exactly threatening.

You’d heard tales of mermen...they were beautiful and deadly. But that’s all it was, wasn’t it? Tales? They couldn’t possibly be true.

You sharply stood, eyes on him as he moved a little taller out of the water in response, revealing a muscular chest. Your breathing was labored as you began backing up, swallowing thickly. He tilted his head a little more, his ash blonde hair cutting across his intense, ruby eyes that never left you.

No words were exchanged as you turned, grabbing the end of your dress and fleeing towards your stepfathers home. When you reached the porch, you paused, gripping the banister and breathing heavily. Part of you wondered if you had hallucinated as you turned, looking in the distance at the dock, only to see the gentle blue waves...no sight of a handsome, blonde man.

((O))

A few days had passed, and you couldn’t get the encounter out of your head. You told no one; you didn’t want them to think you were crazy.

Hell, if you thought too much about it, you thought you were crazy, too.

You had avoided going near the water again by yourself, your eyes constantly searching the water when you were near it. You didn’t see anything again, but in your paranoia...you felt like you were being watched – always. The second you stepped foot outside, that itching feeling of someone’s stare was all over you, making you uncomfortable.

You were warily looking over the water and walking on the dock with your stepfather when you felt a disgusting squish underneath your bare foot. You jumped back, shrieking when you saw a huge, dead fish on the dock. You covered your mouth with a gasp when you saw massive claw marks across its blue scales, obviously killing it.

“Shit, how did that get up on the dock – what the hell killed it?” you stepfather said after running up to you when you shrieked. You covered your cheeks, your stomach rolling in disgust when your stepfather leaned down to pick it up, it’s guts falling on the wood before he tossed it in the water.

“It’s alright, something else will eat it,” your stepfather chuckled, patting you on the back.

You swallowed thickly, wrapping your arms around your torso as he began setting up his fishing pole.

“I…what do you think killed it?” You asked in a high pitched tone, seeing him shrug uninterestedly.

“Could be anything,” he commented, inspecting his line, “ocean is so big that anything could be out there.”

You nodded, looking out over the water with a wary look.

Over the next few weeks, it kept happening. You always seemed to be the one that found the ripped apart, dead fish near the water. Multiple ones kept turning up, and to your horror, they kept getting bigger. You never wanted to go outside again when a medium-sized shark had turned up in your path.

What was worse was that every time you showed your stepfather, he’d shrug it off as though this was normal. You weren’t a marine expert, but you were pretty sure this was weird. You hated it, but your mind kept trailing back to the…merman you thought you saw.

Was he doing this? If he was and he was trying to unnerve you, it was working.Was he trying to frighten you? Why else would he be leaving carcasses everywhere? Of course, you didn’t know it was him, but you began to strongly suspect it.

You were sitting on the sand, rolling a rock in your hand and looking out over the water once again as your stepfather waxed his boat nearby. You sighed at the feeling of being watched, pulling you knees up to your chest and resting your chin on your knee. The sun shined down on the water as you contemplated why you were always out here, looking over the water every time you stepfather came out. Did you want to see him again to prove to yourself it was real?

You sighed, your eyes catching something gleaming at the edge of the shoreline. You paused, lifting your chin from your knees as you slowly stood, walking to the waters edge and crouching down. Sure enough, there was glimmering lights just under the surface, making you hesitate before reaching in the water and grabbing the object. Your heart stuttered when you realized there was a string, and you pulled it from the sand.

Your eyes almost popped out of their sockets when your hand revealed a stunning necklace. It was held together by an intricately braided string, unlike you’d ever seen before. What stunned you was how it was made. There were sea shells and what appeared to be diamonds and serpentine woven throughout the braided chain. You weren’t sure, but they certainly looked like them and you knew both were found in the ocean. The diamonds were cloudy as they were raw, but so gorgeous that they took your breath away. They fit the white of the seashells, and the serpentine added a pop of color.

It was the most unique necklace you’d ever seen. There was a simple tie in the back as you hesitated, then placed it around your neck. You smiled as you fastened it, looking down and running your fingers over the small gems and shells. You heard a small splash and looked up sharply, gasping when you saw a familiar, blonde head near the dock, about twenty feet from you. You stood on the shore, his intense eyes trailing down to your neck, where the necklace rested against your collarbone. For the first time, his neutral expression faded, his smooth cheeks crinkling as he smirked in what appeared to be satisfaction. It made him look more handsome than anyone had a right to.

At that moment, you knew he’d made it and somehow, made it for you. Your fear lessened, but didn’t become totally absent. After all, he was still some kind of sea creature. You glanced over at your oblivious stepfather nearby, noticing his gaze followed yours. His gaze moved back to you when you looked back at him and he tilted his head down as if to say, ‘What are you going to do? Cry for help?’

It absurdly kept your mouth shut as your heart raced in your chest. The sounds of the water and the gulls may have drowned out your words that left your mouth without a thought.

“Thank you.”

To your surprise, you saw his head and shoulders raise in recognition, his massive tail lightly moving the water behind him. It had to be uncomfortable, you thought, to be in the shallow water with a tail like that. It’s clear he’d only came to see you, making your chest squeeze. Every part of you said he was a predator, and you should be wary and worried, but….was he just curious about people? Was the necklace an offering of peace or friendship?

“Honey, could you come help me with this?”

Your stepfathers voice caused you to jump and look over at him as he waved you over. You quickly looked back, frowning when you saw he was gone. Clearly, he didn’t want your stepfather to see him.

You sighed, lightly touching the necklace as you went to help your stepfather.

((O))

“You love swimming, come on!”

It was how you ended up on your stepfathers boat with your mother in the ocean. You supposed that now, you were wary of the water. Not really because of him, but at the same time, it was because of him. Surely, there were others like himself? Mermen?

You wondered what his name was. Did he even have a name? Surely, he did. He didn’t speak and maybe he couldn’t, but his gaze was as intelligent and it was intense. His face was fierce, but incredibly handsome in your opinion. His skin was perfect, and not to mention, his upper body was completely ripped.  

Dear god, were you attracted to a fucking mute fish? 

You needed to get out more.

You were wearing the necklace you suspected he made with your bikini. Absurdly, you told yourself if any other…fish-men saw it, they’d somehow know one of them made it and leave you alone. You hesitated at the side of the boat, looking around the rippling, blue water as though you were going to see a face. It had an eerily resemblance to being too afraid to look out the window at night because you were afraid of seeing a face.

No, you doubted he was here. He went close to the shore when he wanted to see you. You weren’t far out, as the cliffs were nearby. Closing your eyes, you jumped in the water, the coolness rushing over you as you broke the surface, rubbing your eyes and blinking as you watched you legs move, a tad paranoid something was going to touch them.

Your stepfather and mother were drunk, laughing loudly on the boat as they blared classic rock. You rolled your eyes, swimming a bit away from the boat to avoid them. Honestly, you weren’t even sure why they insisted you go. You felt like you were intruding on a date or something. You swam a little further away, sighing to yourself and trying to relax, letting the water lap over your shoulders.

Pain shot fiercely up your leg, making your eyes shoot open before you shrieked and went under the water. Your leg locked up, and it took you but a moment to realize you had a muscle cramp.

Your mind was frantic as you scrambled for the surface, your lungs burning as you prayed your drunk parents would notice. Your vision started blackening when you felt something warm and strong wrap around you and break the surface. You coughed horribly as you felt yourself moving through the water at a fast speed, unable to focus or get your bearings and you choked and gasped. It suddenly stopped and you felt yourself being laid on a hard surface. Your coughing quieted down as your watery eyes tried to focus, making you rub them and blink heavily.

Your spine went rigid when you met a familiar, crimson gaze that was much closer than ever before. His upper body was pulled from the water, his tail still submerged as he leaned on his hands, looking over your body as if to check that you were okay. Your gaze flicked around, realizing he’d taken you to the nearest surface, which was inside one of the caves. Your gaze moved back to him as your heart thundered in your chest. His arms were corded and strong, looking like they should be considered weapons. He had firm pecks and and abs, making your mouth go dry when you saw the black and orange scales begin at his tapered waist, below his belly button. His hands were plastered on the surface next to you, your heart jolting when you saw deadly looking claws. Claws that likely made those fatal gashes in the sea animals left around your stepfathers property…

Your gaze moved up to his face once more, startling you when you saw he was already watching you look him over. It was completely against your will when you felt your face redden, taking notice of his eyes flashing as he clearly saw the change in your skin tone.

He tilted his head, his eyes roving down your body making you blush even more furiously, wrapping your arms around your stomach in embarrassment. Your bikini wasn’t really skimpy, but it still wasn’t a lot of fabric. He suddenly pointed a large, clawed hand at your calf, which was still twitching from the spasm.

“Pain?“

A jolt of surprised went through you as your mouth parted in shock at his deep, gravely voice. He could speak? It was clear that the word was somewhat unsure, and that your language wasn’t his own. But…how did he know? You’d had the feeling he’d understood your thanks, but now, it really seemed as though he had.

“…”

His brows furrowed at your response, or lack of response. His soft-looking lips pressed into a hard line, reaching forward and grabbing your calf, causing you to yelp in alarm. Fear traveled up your spine as you squealed and began to struggle, trying to pull away from his iron grip. He wasn’t hurting you, but the strength you felt in that grip scared you. His claws squeezing into the flesh of your calf.

“No…hurt,” he said in a deep voice, making you go still as you stared at him with wide eyes. His crimson eyes moved back down to your calf, a shiver running across your skin as his cool hands squeezed your muscle, moving up and down your calf with furrowed brows. You couldn’t move, but you felt like he was checking to see if you were injured…what you didn’t expect was the warm tingle that traveled up your leg from his touch, settling in your stomach. You bit your lip, feeling a tad disturbed at your body’s reaction. He was so handsome and strong looking, though.

Jesus, you were trying to justify being a little turned on my a fish?

“Hurt,” he said again, releasing your calf and shaking his blonde head. Clearly, he had deemed you healthy. Part of you wondered if he had just started learning you language a few weeks ago. If so, his understanding was amazing. Just from his gaze alone, you could tell he was very intelligent. However, if he managed to understand and even speak a little bit of your language in that short amount of time…that showed such a high intellect that you couldn’t help but to be impressed. Perhaps mer people were more advanced than humans?

“It was…a muscle cramp,” you said in a low, strained voice, his head tilting and his eyes lighting up at the sound of your voice – as though it made him happy. His face didn’t change, but his ruby eyes were very expressive.

He nodded as though he understood, his eyes moving back down to your legs and cocking his head, looking at your feet curiously. You didn’t move as his hand reached out again, slowly, as though not to alarm you. He ran a clawed finger across your toes, pulling back slightly in alarm when you wiggled your toes in reaction. It was clear that he’d never seen a human this close up before and had clearly never touched one.

Your fear lessened to almost nothing. He was frightening in many ways, but he was also…

Ethereal and beautiful. He had saved you and checked to see if you were injured. If he wanted to harm you, surely, he would have by now? Though he seemed intense and a powerful force to be reckoned with…he didn’t seem like he meant you any harm. Perhaps you were naive for it, but you felt yourself relax.

He was watching you intently again, the only sound in the dark cavern was the trickling of water and your slightly labored breathing.

“What’s your name?” you whispered, watching his eyes go down to the necklace around your throat. His ruby eyes flashing in satisfaction as he looked back up at your eyes. “Do you understand me?” you asked, shifting against the hard rock of the cave and pulling your legs underneath you.

He tilted his head, his eyes searching as he put a clawed hand to his strong chest. “Katsuki,” he said clearly, making your brows raise in surprise that he understood you.

“Katsuki...” you trailed off, jumping slightly when his eyes immediately darkened, a small growl rumbling in his chest and alarming you. You flinched back, causing him to immediately stop and lean a little closer to you.

You looked at him a bit wearily for moments as he waited for you to speak.

You swallowed, putting your hand to your chest. “Y/N,” you said in a soft tone, his upper body angling towards you a little more, his tail making a small wave behind him....as though you telling him your name really pleased him.

He paused, his eyes searching your face before turning and diving into the water quickly. You yelped in alarm, scrambling to the edge to look down into the dark water a bit frantically. Why did he just leave?

You looked around the cave, your shoulders hunching as you became aware of how dark and...creepy it was in here. You could swim back to the boat – did they seriously not notice you were gone?

My god. What if your leg cramped up again? Great, now you were traumatized.

Right as you really started to panic, he broke the surface of the water, shaking his hair out. To your amusement, it went right back to his spiky look as though it wasn’t just soaked. You couldn’t help it when a giggle left your lips, his crimson eyes snapping to you, his nostrils flaring slightly as he pulled his hand from the water, flinging a large, green fish on the rock in front of you. You jumped, gasping as you saw the familiar claw marks on the side of the dead fish, your eyes going wide.

“It was you!” You gasped as his brows raised for a moment, a smile curling his lips. Your heart jumped when you noticed his perfect teeth also had fangs – two sharp canines. “Why did you leave me dead fish?” You asked, tilting your head.

His eyes squinted for a moment, as though he was trying to process how to answer your question. “Hmm…showing interest,” he answered, his eyes gleaming as your face reddened.

Surely, he didn’t mean…

“What do you mean?” You squeaked, staring at him in disbelief as his lips curled in what appeared to be frustration, huffing through his nose.

“Interest…in mating,” he emphasized, your jaw going slack in shock as his eyes moved down to the necklace. “Accepted.” He added, nodding towards the necklace that adorned your throat.

You were reeling in shock. You’d accepted his advances by wearing the necklace he’d made? How was that fair? Surely, he knew that you didn’t know what it would mean.

He huffed, picking up the fish and holding it out to you. You recoiled, your stomach turning at the bleeding body. “Eat. Hungry,” he said, looking determined to make you eat this raw fish. You shook your head imploringly, covering your mouth and attempting to wave it away.

“Y/N!”

You jumped at the sound of your stepfathers voice. Katsuki snarled loudly at the sudden noise, turning around sharply and blocking your view with his large body protectively at the perceived threat to you.

“It’s okay!” You exclaimed, “It's my stepfather.”

His strong shoulders relaxed slightly as he turned to look towards you again. It must be your imagination, but you could have swore a sad look crossed his intense face for a moment. It was almost as if he was sad your time together was over.

“I have to…” you trailed off, sliding your legs in the water next to him as he nodded in understanding. You tensed up when he immediately moved in front of you, his large, strong hands wrapping around your waist. Your breath left you in a rush when he strongly lifted you off the rock, slowly lowering you in the water and supporting all your weight.

“Oh…” you breathed as he towered over you, coming much closer. He was huge as you stared up at him with wide eyes. “I-I…” words failed you as his hands tightened on your waist, his gaze becoming hooded. Your breath was shallow as a soft scent entered your nose. It smelt like the ocean, but it was almost sweet, like caramel.  It was crippling, and you found yourself unable to move or even think as his eyes fluttered closed, tilting his head down. You didn’t even think of stopping him as your own eyes fluttered shut.

The feel of soft press of his lips was unexpected, as was the feel of adrenaline that suddenly started pumping through your veins. Excitement rushed through you as you curled a hand in his damp, blonde hair that was surprisingly soft. He growled in your mouth, and you felt a hand on your waist curl to your lower back, pulling you flush against his hard body.

You weren’t doing this. You weren’t letting a merman kiss you in a creepy ass cave.

His body felt slightly cooler than your overheated one, his tongue sliding smoothly across your lip as though he knew you, as though he knew exactly how to kiss you. Every stroke of his lips and tongue was perfection, making you tremble against his strong body and try to grapple with your sanity as you tugged his hair, trying to somehow pull him closer.

Like him, his kiss was intense and all consuming – as though he was making damn sure you didn’t go home and forget him. It was almost like he was claiming you and reminding you that you belonged to him.

You weren’t sure what was happening, but you continued moving your lips against his, gasping in his mouth and pressing against his hard chest. You breathed heavily when he broke from your swollen lips, moving his hungrily down your neck. Your breath caught as he nudged the necklace with his nose, a low growl sounding in his chest. He nipped your neck with his teeth, a deep, husky word leaving his lips.

“Mine.”

You swore you felt some kind of bulge against your abdomen, confusing you for moments under all your lust as you gripped his hair. He ran his tongue up your neck, tasting your skin possessively.

“Y/N!”

Your stepfathers voice sounded closer now as you looked towards the entrance of the cave, seeing shadows.

Katsuki pulled away from your neck, and you took notice that his breathing seemed a little strained, and his jaw was tight.

It was clear that he didn’t want to let you go.

His nostrils flared with a huff, his bright, red eyes staring into yours.

“Soon,” he whispered in a low voice, his hand running up your bare back, his fingers toying with the strap of your bikini top as his expression turned serious. “I will watch – keep you safe,” he said slowly, making your heart punch your rib cage. His fingers came up to your collarbone, running them across the necklace with a satisfied look on his face. Your breathing was shallow as he lightly ran them down to your cleavage, a shiver running down your spine when he traced his fingers across the tops of your breasts. He looked hungry, like you were a present he couldn’t wait to unwrap.

A devious smile curled his lips, his fangs gleaming as he looked rather pleased with himself at your flustered appearance. He glanced back towards the entrance, seeing flashlights as he looked back at you once more, his eyes lingering on your face before he dove into the water. You barely saw the end of his tail, the orange and black a mere flash since he was so quick.

“Y/N!” Your stepfathers voice called again.

You sighed, trying to catch your breath. “I’M HERE!” You forced yourself to call out, your mind spinning and unable to process the fact that maybe, just maybe…you’d unwittingly bound yourself to an intense, admittedly handsome…merman.

i don't have many thoughts about merman bakugou, but today i did think 🥺 about him coming onto land and having his legs, all human-like 🥺 but there's always a little glitter to him, almost like sand shines in his skin 🥺

[kaidabakugou]

merman bakugou came to fuck me in my dreams and now i’m not ok.

just being stranded in the middle of the sea, paddling your small row boat. only the light from the moon illuminating your path as you continue searching for land.

deciding to stop on bioluminescent waters, the blue glow emitting from the movement of the fish around you bringing you comfort. taking the time to remove your wet clothes and set them aside to dry, since navigating at night won’t be of much help anyways.

leaning over the edge of the boat to dip your hand in the water, the warmth lulling you to sleep. failing to notice the bright set of ruby eyes stalking towards your boat, where you are naked and defenseless.

i may or may not have started a whole fic on this even tho i have a field of wips i want to get done :)

A Love Song From The Deep by MadameButtButt

His pod has always feared the Dragons, the alien clan that dwelled among volcanic vents of the deep, and with good reason. No one has seen one in generations, but Izuku heard stories of blind, listless things that drifted along the sea floor like ghosts.

Wherein Izuku is a curious merman, and his new friend is very fascinating.

whirlpool by pinchingzuku

Summary: He still didn’t know how he, a mer, ended up being friendly with a human of all things. It still made his brain spin and his fins flicker in annoyance, maybe less than he would have liked, but still.

And definitely didn't expect to see him again, and again, and again.

The sound of the waves by Ana_Writes

Summary: Love is beautiful, everyone knows that. Everyone sees it differently. For some it's the feeling, for others it's the person.

For Izuku? For Izuku it's the sound of the waves.

Being in love with a merman isn't normal or easy but Izuku knows he'll do anything to see Katsuki's face, feel his scales on his skin and hear the soft hum of the waves.

tides by kindaopps

Summary: A new lease of life, then, for this poor boy. 

A whim, nothing more. Katsuki’s good deed of the day. It’d be a waste, to let the life he’d saved slip away in a blink of an eye. 

Katsuki ignores the treacherous voice inside him that tells him that his whim had something to do with the dream-like, nebulous future that Katsuki saw in glimpses.

Sharks and ocean predators by @silverynight

Summary: He's ready to dive in, when he sees a very weird black and dark orange fin, it looks like a shark's. He knows sharks are not usually aggressive, but he doesn't want to upset it, so he decides to stay on the boat for a while, hoping it doesn't see anything interesting and decides to go away.

However, the shark doesn't go, instead it bumps into Izuku's small boat a couple of times until the green haired boy falls into the water.

Izuku closes his mouth and opens his eyes to see the creature and realizes that's not a shark but a merman; he's never seen one like him before. Uraraka's fin is completely different from his; from the waist down he looks like a black shark and the rest of him looks like a blond boy with red eyes, sharp teeth and well built body.

mer-made in heaven by Fangirl_on_fire

Summary: Over the next few weeks, Izuku kept returning to the cove. He brought a few gifts for Katsuki—slices of dried kelp, a pretty shell, things he had figured out mermaids often liked from his studies at the laboratory—but Katsuki never reacted beyond a slightly interested lift of his eyebrows. Still, Izuku was lucky just to have the attention of the most gorgeous person he had ever seen, mer or human.

As if it weren’t enough that Katsuki was devastatingly handsome, he was cute, too, with the way he scrunched his nose up when the sunlight hit his eyes or he idly splashed his tail in the water.
