I think that's all, but I'm bad at warnings. Also, there is slight control over the mind, but everything is consensual! Word Count: 7,222 Requested: Yes! Author's Note: I used several references while writing this including Pirates of the Caribbean, H2O Just Add Water (literally only the moonpool/grotto area, that's what the scene is based on), and the faces I envision the sirens having is basically the vampire faces in "The Vampire Diaries." I also watched One Piece while writing this. Avatar (James Cameron) also inspired the mermaid/siren sex biology. (When they use their hair to touch and that's sex, yeah I did something like that). Reader is a pirate that basically only uses pirate slang around her crew, besides that she talks normal. I figured the pirate slang would get annoying to y'all, so I kept it own. I hope you like it!

EDIT AFTER POSTING: Y'all be making me blush and shit with your feedback. I'm giggling and kicking my feet <3<3<3

For hundreds of years people have roamed the oceans. From sailors on ships to the deadliest pirates of the seven seas, the treacherous waters have taken many lives, not only to the water itself, but the unknown dangers of what lies beneath its surface.

Stories of many kinds have stumbled their way out of survivors and drunken deadbeats. What they saw at sea or what they heard from someone else, anything was plausible in this kind of world. If it came from someone’s mouth, it was bound to be true in one or another. No one can ever be careful enough, so it was better to take everything as truth. Even the most ridiculous sounding claims shouldn’t have been taken lightly.

You were the captain of a large pirate ship named The Corruption. You weren’t the most feared pirate known to man, but you were certainly amongst them. You were the only pirate willing to tread where others never came back from. You had faced the Kraken, not killing it, for your adventure only called to find where it rested to avoid crossing near the area at all costs. You faced several other sea monsters, whether they were larger than three ships or nearly as small as a minnow. In this place, the unknown were considered monsters until proven friendly. You and your crew were one of the reasons the unknown creatures were given names in the first place.

People often wondered about the name of your ship, The Corruption. As far as anyone knew, you weren’t one looking for a good or quick fuck like anyone else when drunk, stressed, or just plain horny. Anyone who would have ever heard your name knew you were one of the bravest captains in the known lands, but they also knew you weren’t one to hurt.

You were known for finding creatures but never hurting them. You never forced your crew to walk the plank or make a sacrifice. You were feared for confidence and bravery, not unjust corruption like other pirates. The name of the ship didn’t make sense. How could you, a captain so understanding, sail a ship with an unfit name? Everyone wondered. But you knew. Only you. Only you had the actual mindset to understand why it would be given such a name, and it was simple: Those who sail on it are corrupted by the wonders, those who sail on it live to tell the tales, and thus are corrupted by the truthfulness filled in the sea. They were not killed, they survived intentionally, as long as the captain had any say in it.

Though there was no reason to fear you, people were still terrified because you were willing to explore what others wouldn’t dare go near. You didn’t take shit from anyone. Your very presence, the kind that was filled with confidence, your willingness to look anyone in the eye, and you could get anyone to tell the truth. You could read a lie from nautical miles away.

This next voyage of yours was not the most dangerous, but somehow it scared the crew and anyone new willing to sign up. You were on the search for something that was only legend. Nothing proven, no one alive to tell the tale, and it was strictly based on sightings, no real interactions. For years there had been narratives of half fish, half humans swimming by ships quickly, like they were doing their best to not be seen. Oftentimes the quick glimpses made were described as beautiful women, long hair flowing down their backs and breasts out with no cover. The Englishmen called them “mermaids.”

You wanted to see them for yourself. It was what you did: searched for the tales, or in this case tails, to prove they were real, and if they’re dangerous and how to avoid them. But you questioned why they were so afraid of beautiful maidens that swam along beside them.

Annoyed by everyone’s lack of commitment, you rounded up your crew and anyone else interested in the voyage.

“What the hell is wrong with this lily-livered crew? You wanna sail, especially on my ship, you’re gonna get the hell on and go. What happened to me swashbucklers?! You have faced the kraken and you’re all scared to go hunt for half fish half humans? Now, all hands hoay!”

Your crew didn’t move, barely budged actually, they just blinked at you. Until one man stepped forward and spoke up.

“Captain, we don’t mean to seem like landlubbers, but rumor has it these mermaids ain’t that friendly. Says they sing with perfect pitch and harmony to lure anyone to their deaths, then snack on them like we’re a hearty meal. We ain’t wanna die to the hands of lust, ya hear?”

In disbelief by such words and rumors you had to understand it was important to be cautious. This wasn’t the type of journey you could just set sail for, it seemed there were more obstacles. You had to come up with more of a plan than a simple aboard ship and sail off.

“If these ‘maids are so dangerous then why is it they swim by our ships without going in for a snack, aye?”

Another mate spoke up to answer your question.

“Captain, it’s been said that they could be related but they ain’t the same creature, savvy? Rumors been calling the ones who sing ‘Sirens’ instead of mermaids. They look the same, but they await on shores singing to lure them whereas mermaids are friendly, helpful fellows.”

“Ya sound like you’re three sheets to the wind. Where’d you hear this scuttlebutt?”

“Came from an old seadog, Captain Rattles, Captain.”

You thought for a moment. Captain Rattles was one hell of a source, to be honest. He sailed the seas for decades, every warning he ever came about ended up to be true. Never once had he lied to crews and captains. He was a pirate to behold, really.

“Fine. I’m gonna have a meeting with Rattles to figure out a plan. Then all of you are boarding my ship, or else you’re gonna find yourselves lovers with the hempen halter. Savvy?”

“Aye aye, Captain!”

And the mates scurried off while you made your way to the old tavern where Rattles always seemed to be. It was time to figure out what you were gonna do with the ole hearties. It was annoying to you though. They were willing to die by a giant octopus and not a pretty girl. Typical pirates looking down on women.

Later that night you found yourself seated next to Rattles with a notebook to take notes on anything he had to say.

“I remember encountering them for the first time. We heard a beloved voice and heard it coming from a distance. We saw a mermaid. She turned on her back and swam while her mouth opened. The song came from her. We were all entranced. We followed through a fog until her song became a screech. Her face contorted, and her teeth became sharp fangs. The fog dissipated. Then there was a colony of them. They looked so peaceful in the water, until they all did the same thing. They began to attack. It didn’t help that the ship was smaller. I barely escaped. Only me and two others got out. Everyone else was ripped apart in front of us or dragged into the water where the carnage was hidden. We aren’t sure if there were survivors. We aren’t sure if sirens and mermaids are different or if one makes the other. There are so many things we don’t know, but no one should trust a half fish, half human. It’s not safe. We need someone to figure it out. We need you to figure it out.”

“I know. I want to. My crew is scared.”

“Come on, Captain. Let’s figure this out.”

“Aye aye, Captain.”

That night over drinks the both of you came up with a plan. You and the crew needed to wear cloth in your ears to prevent the sound of songs from working. You needed to stack on weapons, ready to attack back. You all needed to pretend that the song was working. The plan was to sail east off the island. That’s where they accidentally found the cove they named “Libido’s Lounge.” It was noted that there weren’t just women, there were men as well. Even those who didn’t fancy men still fell under the spell, and vice versa.

A few weeks passed by while you gathered the supplies you all needed for the voyage. It was dangerous, and those who began to board knew that. Even you, the bravest of adventurers, were slightly trembling as you boarded last. You weren’t sure why you were so nervous, but you had a gut feeling this was not going to end well. You wanted to cancel it because you’ve never had a gut feeling like this before, but it was too late. You had to go through with it.

“Anchors aweigh! Better get your sea legs in quick because we’re in for a ride!”

“Aye aye, Captain!”

The escapade took a few weeks. The bad feeling in your stomach grew worse. Some days you could barely walk, the anxiety crumbling you. Your head had shooting pains that grew worse the closer The Corruption got to Libido’s Lounge. The crew noticed, but they refused to say anything. It's never good to doubt the captain, especially when they’re in this position of danger with no one else to lead them out.

Dark grew over the horizon as the sun hid itself. The ship continued to sail onwards until a crew member looked over the deck and saw a beautiful face emerge from the water. She smiled at him, and he smiled at her fondly. The way her face was beautifully carved made him feel butterflies, and it wasn’t just the fact that he’d been living off of rum for a while. A crew member next to him noticed his gaze followed towards the girl. He quickly ran towards you to alert you that you’d reached the cove.

“Alert the crew to get the cloth in their ears, now. Get Barbins over there out of that trance or he’s gonna be feeding the fishes.”

“Aye aye, Captain.”

Without a second to lose he began to round up the crew one by one to let them know the plan needed to go into full effect now. They plugged their ears with cloth.

“Hey, Barbins.” The man whispered.

Irritated, he turned to face him.

“What is it?”

“Cloth, now. Captain said so. Or you’re gonna be dinner for them.”

“Gyah, whatever!”

He stuffed his ears quickly before facing the pretty girl again. She smiled, and he smiled back. You noticed this. She began to swim away, and you quickly alerted the crew to follow her. You grabbed a hold of the wheel and spun it to change direction. Through the mist you blindly followed the girl.

“Oi! Be ready for anything. The second her face turns ugly, start attacking!”

The mist cleared and water grew shallower. There was a clearing filled with the most beautiful faces ever seen. You glared at them as they opened their mouths and began to sing. Through the cloth, all of you could hear the song, but you were hoping it stopped the hypnotic way it enchanted the ears. They all stared at the ship while they harmonized their song. But you couldn’t see any men. Your father had told you there would be men, but there were none here. They were all beautiful girls, you could admit to that. You saw the attraction, and you understood the danger of their beauty.

You looked to see Barbins jumping off the ship. You were stunned. What was he doing?

“Man overboard! Start the attack, now!”

WIth a yell the men began to shoot at the water, and the creatures became angry. Soon they lunged at the ship, managing to grab hold of the crew and dragging them down to the depths. There were way more of them than you had crew, and you knew there’d be more to come.

Honestly, you lost your depth. Your stomach grew more knots as you watched the bloodshed. There was going to be no survivors by the look of it. Your head felt full and heavy. Your vision became blurry. Your legs felt weak. The epitome of this dreadful feeling somehow worsened when you got to the clearing, and it hurts even more now, like the source of it is getting closer.

You began to back away from the wheel when you felt yourself hit the back of someone’s chest. You wanted to turn around, but you couldn’t move. Two arms arose to your ears on both sides of your head and pulled the cloth out of them. Then one arm wrapped around your throat and put you in a chokehold while lips quietly sung in your ear.

“Dead men tell no tales.

Ugly men raid our seas

So we tear their sails

And hear their begging pleas.”

A mate saw you in danger, so he began to run towards you. The figure who grasped you hissed at him while his eyes shriveled, veins protruded, and fangs threatened. The mate didn’t back down, so the stranger put you down and lunged at him. He quickly sank his fangs into his shoulder and tore a bite right through him. The mate cried before he was pushed overboard.

You tried to flee in the distraction, but you weren’t fast enough. Furious at your attempt to escape he continued to sing as he stalked towards you.

“Dead men tell no tales,

But you my sweet

Are beautiful as my scales

You’ll stick around as my treat.”

He grabbed you by your arm and pulled you toward the ship’s main deck. You were confused by the man’s ability to walk if he seemed to be the same creature as the ones in the water. Your head hurt too much to fully wrap the idea in your brain. Another mate tried to go for the enemy, but he was knocked to the ground.

“W-what is g-g-going on?” You tried to speak, but you only stuttered the words.

“My name is Hyunjin, and you attacked my kind. That does not go without punishment.”

He pushed you overboard into the water before diving in right behind you. You swam to the surface as best as you could until you were pulled underwater by Hyunjin. His legs were gone, and they were replaced with an abstract tail. It was a warm brown color with hints of crimson red and golden yellow. Though he was a being that belonged to the sea, his tale resembled fire with its colors and extension fins like that of a betta fish. The colors felt inviting.

He placed a kiss on your lips which then gave you the ability to breathe without worry. You tried to fight against him, but once he began to sing with his beautiful voice you were lost again. You stared blankly at him as he took your hand and swam away with you, leaving the war to finish itself without guidance.

Hyunjin swam towards a vacant grotto where he laid your body on a rocky surface. The grotto was his secret hideaway. The only life around it were the fishes and the plants that danced in the water. Hyunjin kept his tail in the water while he laid his arms on the rock staring at your unconscious body. He couldn’t help himself. There was something about you that captivated his attention. Your breathing was calm, you felt lost. You couldn’t think proper thoughts, and you were lost in a void where there was everything and nothing at the same time.

He wasn’t sure what it was. There was something about the way you lead your ship through the mist, thinking you were being strategic, but he stalked behind the ship the entire time. He grabbed onto the side of the ship, beginning to climb his way onto it and watching the scenes unfold. He noticed you were teetering while you ordered your crew around. He could tell you weren’t entirely there. There was a feeling in his stomach that made him want to help. He felt compelled to aid you. He wasn’t sure if it was your bravery for willingly going where every man fears or if it was because you were the most beautiful face he had ever seen. Even though he was and lived amongst a species that matched the beauty of gods on earth, no one looked as beautiful as you.

He was supposed to be the one who lured people into his trap. That was what being a siren was about. He wouldn’t sing so beautifully if it wasn’t for that. Even before he was trapped in this cursed body, women would swoon over his artwork. Every woman would look at him lustfully, some of them were quite attractive, but no one was ever able to catch his eye. So, why are you, some pirate trying to kill off his kind, making him feel ways he has never felt before? That wasn’t fair. That defeated the point of all of this!

He found himself caressing your head softly, staring at the way the water soaked clothes clung to your body accentuating every nook and cranny of it. His body tingled in ways it hadn’t in awhile. Excitement filled his face while he watched you breathe steadily. There was something about the way you were under his spell, under his control, that turned his brain to goo. His mouth began to water, his face felt hot, and his head started to ache at the uncontrollable feeling of wanting to touch you and make you scream his name, but instead of begging for mercy to live you’re begging to have him touch you more and more. The thought alone made him groan.

You began to wake up from your hypnotic state, stirring slightly, eyes blurry, blinking back to reality only to be met with the high ceilings of a cave and an uncomfortable pain in your back from lying on dirt. Human nature made you want to bolt upright and run, but your pirate nature wanted you to remain calm, find a plan, and escape danger without causing a disaster. You laid there, eyes open, trying to avoid the small sounds of splashing water and the glaring gaze of your captor’s eyes digging into the side of your head attempting to read your thoughts.

“I know you’re awake, Captain.” He taunts you with your title. “For the Captain of a ship, you’re certainly pretty inferior and weak right now.”

You grunt at his comment, starting to haul yourself up to find a way out of this mess. As you stand, you’re immediately stopped when a blissful tone reaches your ears, and once again, you don’t have control over your own body. You can feel it. You can feel yourself wanting to resist but being unable. Hyunjin speaks.

“Ah ah ah, darling. Lay back down. We are not finished here. I told you that you’d be punished.”

His words made chills sprint across your spine. Your cold, goosebumped covered body felt warm from nothing, and you felt yourself melt back to the ground. You turned your head towards his, and he lifted himself out of the water and hovered over you when his tail became two long, clothed legs. He looked at you too, and you daringly stared into his eyes. Within them you saw lust and desire, nothing more and nothing less. Well, there was something more, but you couldn’t decipher it.

Hyunjin bent down and crouched next to you, cupping your cheek and gently caressing his thumb over reddening skin. He stared into your eyes, reading them, finding your scrambled thoughts.

“You need to be good and listen to me. I can’t keep making you listen to me by using my voice, but if you make me, then I will. Am I understood, Captain? Nod your head if you understand, pretty girl.”

You nodded your head. You did understand, but the nodding of your head was not on your own free will. His touch made you burn more. There was something about his over looming presence that made you feel small. One thing you always hated was the belittling you dealt with when it came to being a woman in a pirate’s life. Always trying to act above you when you know damn well it’s for their own ego. However, Hyunjin was alluring to you, equally as much as you were to him. There was something about his confidence and dominance that made you horny instead of angry. Maybe it was because it wasn’t his ego talking, it was just who he was. He knew he was in control here, and that’s why he didn’t feel nervous around you. The other men who made comments towards you always ended up being the weakest. Not Hyunjin though, nothing about him seemed submissive.

The horrible feeling in your stomach never subsided. It grew even more in the position you laid in, and you started to wonder if the wetness in your panties is more than the wetted undergarments from being dragged through the sea like a monster’s prey. Maybe the horrible feeling in your stomach was just your gut feeling telling you to get dicked, and there was something about the nearing presence that made the feeling grow.

Sirens, you think to yourself, are lust filled devils that overwhelm one’s desires when they approach them. Their songs do not force falsified love into someone, but overpowers their primal desires more than they can bear, weakening them, and taking them as food. But why do they want to hurt us, and the sighted mermaids want to help us?

Hyunjin sang another tune, but it made the hypnotic effect wear off, almost like an anecdote. You didn’t move, too afraid for your body to not be your own anymore.

“Tell me, Captain, do you want me?” He asked boldly.

You looked him deep in his eyes. You wanted to deny it, you really did, but just as they claimed, he was as beautiful as they came, more than likely the most perfect one, even beating the gods’ beauty. You wanted him in many ways, and he wanted you all the same. Like the bold pirate you were, you spoke up.

“Yes, I do. Do you want me?”

“Yes, surprisingly I do.” He wasn’t lying. You knew it, you could read lies, and even if it was in his powers to be able to lie without getting caught, this seemed too desiring to him. His breathing was barely steady at the start. He was struggling to hold back.

He moved to plant himself between your legs and then moved his hand to your neck and applied pressure to the sides of it carefully, taking away some air, but not a lot. You gasped, trying to take back all the air he cut off but failed.

“It actually pisses me off how much I want you. Do you know what I’m supposed to do with invasive pests like you?” He leans in closer.

“I’m supposed to rip you apart, limb from limb, and drag you down in the deep to eat you…”

He comes closer, grip tightening, his mouth right to yours, hovering above it just barely.

“But something in me, something about you, makes me want to rip you apart for my own sake, and I want to hear you cry my name while I do.”

He releases your neck and puts his lips to yours. As he makes contact, you kiss back. He isn’t sweet with it, you aren’t either. His kiss is rough, teeth hooking onto your bottom lip and tongue prodding its way into your mouth while he uses one hand to hold himself up and the other to roughly massage your breast while he rolls his hips between your legs to give your clit the smallest bit of tension. He rolls over with a rhythm, enough to make you let out small, pleading whimpers. He smiled, hearing you fall apart on nothing when he’s just begun.

He moves, and he begins to peel off the damp clothes from your body. You want to shiver, you want to be cold when your entire naked body is exposed to the elements, but it only burns. You can barely think, and it’s no longer the lack of air’s fault or Hyunjin’s songs. It’s just how horny you are for this angelically handsome devil. He takes off the rags that hide him as well. The sight of his slightly toned chest and thin stomach fills you with more desire than before. Then he removes his pants, and that makes your pussy throb the most.

He leans back down to you, except he faces your core, and leans in for a meal. The spit from his tongue meeting your untouched folds makes you shudder, and you grab his hair and pull him closer on instinct. His tongue licks in and out of your vagina and messily makes his way to your clit where he sucks on it and nips on it slightly. Your sensitivity is so intense that you feel yourself leak a bit more over his face. He continues his assault on your clit while his hand makes his way to tease around your hole before entering one finger, and a few thrusts later adding a second.

“Hyunjin, fuck-” You moan while he continues his actions. He takes his mouth off of your clit for a moment to say, “Good girl.” You gush at the nickname and turn your head to the side to hide from how excitedly the praise made you feel.

The knot in your stomach was ready to be untied. Your quiet whimpers and moans got louder and increased, which signaled him to pick up the pace a little faster.

“Whenever you’re ready. Just sail with the wind, Captain.”

As soon as he said that, you released onto him and rode out your high as he calmed his movements before pulling away. Your eyes felt heavy, your body felt relaxed, but you didn’t want to stop there. Hyunjin didn’t either. You fell limply onto your back when Hyunjin moved himself from you.

“Hey, there, pirate, we aren’t done with this voyage of ours yet.”

Looking down at you, he bent down and picked you up by your hips, moving you to sit in front of a rock on your knees. The rock was at your eye level. Hyunjin sat on top of the rock. He slightly flinched at the coolness of the rock against his ass, but he warmed up to it quickly. He spread his legs, leaving his dick out, and the perfect space for you to crawl in and suck him off. You stared at his long, hard dick while it waited for attention.

“Hey, princess,” Hyunjin snapped his fingers in front of your face. “Get to it.”

You crawled to him on your knees, head bowing down in embarrassment, but Hyunjin grabbed the roots of your head and pulled you close to his dick. “Open.” And you did. You opened your mouth wide and took him in while he kept his hold on your roots for physical control. You bobbed your head up and down, moving your hand up to grab what you couldn’t reach, but Hyunjin stopped you.

“You’re a Captain, aren’t you? Using your mouth to bark orders all day? Not to mention how much you unhinged your jaw to take me. If your pretty mouth can do those things, then you can suck my whole cock without taking a shortcut with your hands.” He pushed your head all the way on his cock, making you gag, but he ignored it. He kept this up, barely letting you breathe. All he did was assault your throat with each thrust making him groan at your warm, wet walls that felt like heaven’s touch. You could feel your throat become sore, but you honestly didn’t want to stop him. There was something about the way he sounded and his control over you that made you want to please him forever.

Not long later, his groaning increased and became louder. He was going to cum soon, and you could tell when he pushed your head into cock faster.

“Fuck!” He moaned when he felt cum spurt from his tip. He calmed his pushing, but he made you keep your mouth around his cock until he was fully finished, then he withdrew himself and forced you to swallow all of it.

Drool was falling down your chin, your jaw and throat hurt, your scalp was slightly burning, but your eyes were glazed over, wanting even more of him. You felt like you were floating, the pain in your body making your pussy wetter. Even though you felt like Hyunjin was controlling your body with the way he used you like a toy, a new melody filled in your ears making the ache in your body reside. Each tune he sang seemed to do a different thing, but each of them were helpful in the situation you found yourself in. This tune didn’t put you in his control, but it rather settled you to be comfortable for what he was going to do next.

Hyunjin stood up and looked down at you while you remained on your knees. He brought his hand underneath your chin and forced you to look into his eyes.

“Tell me your name.” He spoke. His tone was stern. It wasn’t like the way he spoke before, this was a hard command. You weren’t sure why he was so stern about your name and not the intense oral sex you performed on him moments ago.

“It’s Syrena.” You lie.

Hyunjin grips your chin tighter and glares daggers at you.

“You’re lying. Tell me your name.”

“Ariel.”

Hyunjin pushed your head to the side harshly before bending down and grabbing you by the base of your neck and forcing you to look at him again. This time he’s much closer. He’s more intimidating this way, and you feel your stomach jump.

“Lie to me again, and see what happens. Tell me your name or I will leave you here to die.”

“My name is Y/N. Captain Y/N.”

“Now was that so hard, Y/N?” You glared at him, tempted to rip out of his grasp and kill him on the spot, but you didn't. You stayed put because your sinful temptations were getting the best of you.

“Captain, Y/N.” You corrected him. Even though he’s been calling you pet names since you got there, now you were starting to grow tired of his taunting and teasing. You let him have his fun, but now you wanted your respect back. However, you were basically willing to do anything for him to fuck you at this point, but you didn’t want to admit that.

“No, no, no,” He paused, lifting you by your hips again and sitting himself back on the rock. “You are no captain to me.” He sat you slightly on his lap, grabbing his dick and teasing your clit. Your arms were wrapped around his neck to keep you up. The feeling made you whine loudly. He smirked, slowly pushing his head into your soaked cunt until his long length was fully inside you. Your head fell back, and your mouth opened without control as you let out of the loudest moan you could muster. He used his hand to bring you back to face him and look into his piercing gaze again. Your mouth stayed open, moaning with each small thrust he gave as he pushed himself into you, but keeping most of his dick inside you.

“You are just a pathetic, cock-hungry, submissive, girl.” He said between his small thrusts.

“H-h-hyunjin, please.” You plead. He gives an evil smile and lets go of your neck making it fall back again. He stood up, holding onto you, bringing you off of his cock almost entirely before harshly thrusting himself back inside. You couldn’t control your reaction, even if you tried. You screamed in pleasure, the noises echoing off the grotto’s walls. He continued to plow into you, but it was enough to ensure it was pleasurable for the both of you and not just his own selfishness.

“Hyunjin! I can’t- Fuck!” You moaned.

“Yes, you can. Fucking take it.” He growled, fucking into you harder.

“Ah- I can’t, please!” The pleasure was insane, impossible to describe. Then, again, there was another new melody that rang through your brain, and you felt like you were floating. You were able to take whatever he gave you without worry, but the pleasure somehow doubled. Your eyes were oceans with the way the tears spilled from them each moment he didn’t stop. But everything was bliss. Everything was perfect. You felt more relaxed and calm than you ever had before.

Hyunjin switched the positions you were in, lying your stomach against the rock, and your ass in the hair where he entered you from behind and held onto you by your head fucking into you even deeper.

“My little pirate taking the cock of her enemy.” You wanted to correct him, tell him that your intention was to learn about them, not to hurt them, but that thought left your mind as soon as you had it. You couldn’t think. You were almost brain dead, only being able to feel everything he was giving you and more.

“I’m gonna cum soon!” You managed to choke out.

“Fuck, baby, me too.” He groaned back.

“Ah, Hyunjin, please, I can’t hold it.”

“Just a little bit. I’ll tell you when you can cum.” His stern voice was back, there was no choice whether you did or didn’t on your own terms.

He moved out of you for a brief moment and turned you around to face him. Quickly and carefully he picked you up and thrusted his cock into you. You shoved your face into his neck, kissing and sucking and biting him to bare the orgasm building inside you.

“Can I please-”

“Yes.”

As soon as you released, Hyunjin did too, fucking his cum into you while you moaned. He found your lips and kissed you while slowly walking towards the moonpool of water and allowed himself to fall in with you while you kissed him lustfully and passionately, and he did the same.

In the water, you were lost, eyes open, but not having control. Hyunjin’s presence was not absent from you, but you still felt sexual pleasure. You weren’t sure how.

Hyunjin was in front of you, facing you, and smirking. You looked at him, confused as to how you weren’t sinking without him holding you and without swimming. Then you realized you couldn’t feel your legs. You looked down, and your legs were replaced with a shining mermaid’s tale and extensions of a betta fish, just like Hyunjin’s, right in front of you. You noticed one betta fin of yours and his were connected. That was where the pleasure was located.

You wanted to scream and cry. Hyunjin could tell, so he came closer to you. He held your face in his hands again, stroked your cheeks gently, and leaned in to kiss you. You happily kissed back. Within the midst of your kiss, your tails intertwined with the other, and you felt like you were floating again, but this time it wasn’t Hyunjin’s range of melodies, it was a tone that felt like love. You felt whole and safe. You didn’t freak out about the mermaid tale that now lined your body.

Hyunjin moved away from your lips, grabbed your hand, and swam you towards the surface of the water. After breaking the surface, you began to speak, but he stopped you. “Don’t freak out. You will be fine.”

The second his tail was entirely out of the water, he had legs again, and he helped you out of the water where the same thing happened to you. Hyunjin grabbed you again, and held you into his lap bridal style while leaning against a rock. He looked at you, and you looked at him.

“Humans can’t have sex with mermaids or sirens without turning into one of us. It was a curse put on both humans and merfolk such as ourselves years ago when a human and a mermaid fell in love. However, a jealous sea witch grew envious of their relationship, and put a curse on mermaids that they’d become lust filled demons that killed humans that came near, and anytime a human had sex with one, their curse was to become them too.”

You looked at him dumbfounded.

“What the fuck?” is the only thing you can muster.

Hyunjin laughed and explained more in depth.

“I wasn’t always like this. I was a human too. In fact I was a painter whom all the ladies fell in love over. I adored it. I adored their attention. One day, while I painted by the seaside, I heard a beautiful noise come from the water. I discovered a boy peeking out of the water. He extended his arm to me, I gave him my hand, and he pulled me in. Then, things escalated, and now I’m like this.”

“But I still don’t understand the mermaids and sirens thing. And why’d you have to do this to me? What the hell.” You felt a lot of emotions, but you weren’t as mad at being a siren than you thought you’d be. Depending on the conditions, being part fish could help yourself as a pirate captain.

“I barely understand myself, but I’ll try to explain more. It used to only be mermaids. That was it. Mermaids are beautiful creatures that swim in the sea and have beautiful voices that can do all sorts of things like lure people in and make them feel better. However, mermaids were never inherently evil. Their songs were meant to lure people in for good things, like steering life away from dangerous areas. However, the sea witch’s jealousy got the best of her. She wanted to be the one the human fell in love with, but instead it was someone else. Blinded by rage, she cursed any mermaid who dared fall into the lust trap. Oftentimes mermaids are used to resemble purity because of this, and they distract themselves from carelessly falling into anything that can change that. The sirens curse, it wasn’t just motivated sex, it was killing anyone who tried because the lust was so strong. When the mermaid was first turned into this monster, she kissed his neck, but began to rip it apart. The sexual desires began to settle after the fact, like killing someone brought down the hunger. No one has been able to find an alternative. As for me turning you… I couldn’t help myself. Ever since I saw you there was something about you I needed. It ached, in ways I couldn’t explain, and I knew you felt it too.”

You stared blankly at him in disbelief. Then you spoke up.

“We weren’t coming to hurt you. My pirate ship is more of a learning experience. We discover things in the sea and tell others about it. We don’t harm anything, we just teach ourselves. Granted we know how to defend ourselves in an attack, but we came to study the mermaids, and we ended up in a killing trap. Now all of my men are dead.” Your voice turned cold by the end, just remembering the bloodshed of the battle you were ripped from for no reason.

“But you began to attack, don’t deny that.”

“It was self defense. We knew you were going to do something.”

“I don’t doubt that. Even though I haven’t always been a siren, I can’t sit back and watch my newkind get slaughtered. I will defend them, and now you will too. You’ll learn to.”

“Hyunjin, I didn’t want any of this.”

“But you were so beautiful, I had to have you. You’re mine; you belong to me. If you didn’t, you wouldn’t be so off balance when I’m around, just like a bit ago when you lost everything the second I was completely near you. I hadn’t even started singing.”

He was right. You knew it too. He was the reason you felt off. He was the reason you were off balance and off guard and off everything. Now he’s the reason you’re part fish.

“You can go back to being a pirate captain, if you so please, but I am so deeply infatuated with you, I couldn’t bear you to go. I don’t ever want you to leave me, Y/N.”

It was the way he stared deeply into your eyes that made you melt. There was no convincing melody of his to convince you to stay, though you must’ve had that too now if you were one of them. But his eyes, his pleading, and the slight fear you had of him kept you put on his lap.

“Come, my treasure, explore the ocean with me.” He said, standing you up, and bringing you to the water, jumping in with you, grabbing your hand, and swimming off.

Your tail made you swim as a pace that was hard to comprehend. You were out of the grotto and near the island you sailed off of in minutes rather than the days of voyage you spent. Hyunjin showed you all about the water, pointing out friends and foe, things to eat, ways to improve your life as a merfolk.

Down in the water, the two of you faced the other where your betta fins touched, bringing you closer into a kiss. The two of you chased each other around, creating tiny waves in the water as you playfully messed around.

Resurfacing from the water and staring at Hyunjin, he sang,

“My heart is pierced by Cupid.

I disdain all glittering gold.

There is nothing can console me,

But my jolly sailor bold.”

You smiled, happy to hear this song that he sang often. He sang it about you.

But little did you know, that song is the only reason you stayed with him.

Hyunjin found you perfect, so beautiful that he couldn’t let you go. He knew you would've left the second you had the chance, but he can’t let someone he’s besotted by go, so he’ll do what he can to keep you around a little longer. I mean, he did tell you that bullshit story about sirens and mermaids. Had he been turned into a siren by a boy with a freckled covered face? Yes. Was that witchy nonsense true? Of course not. But if you believed him, who cared? He turned you into a siren on his own, so he could keep you around forever. He was going to have you no matter what.

You are his treasure, not any of the pirates, his.
