I want a steamy story where a mermaid Prince falls in love with a pirate captain. Though the pirate captain is so tranced that he can’t help but falling in love with his little merman.

Chapter 1: The Merman's First Lure

The water was a second sky, cooler and heavier, filled with drifting constellations of light. Caspian drifted with them, his emerald tail flicking lazily, stirring the bioluminescent algae into swirling galaxies. Above, the surface was a shifting mirror of bruised twilight, bleeding from orange to deep purple. This was his time. The time when the border between his world and the Other World felt thinnest, a permeable membrane of curiosity and ancient law.

He should be hunting for squid near the thermal vents. He should be practicing the old songs, the ones that could calm a tidal surge or coax a pearl from the deepest oyster. But the familiar, weightless silence of the deep was suddenly pierced.

It was a sound like nothing he’d ever known. Not the click-and-whistle of dolphins, nor the low hum of a passing leviathan. This was ragged, rhythmic, and full of a strange, aching weight. It cut through the water, a vibration that resonated in the delicate bones of his jaw.

He stilled, listening.

It was a voice, he realized. A human voice. It was singing.

The law was clear, carved into the memory of every mer-folk from birth: The surface is seen, not touched. Their world is not for us.

But the song… it hooked something deep in his chest. It was a story of loss and a distant shore, of stolen gold and a wooden box. The melody was simple, but the feeling behind it was a complex riptide, pulling at him. He found himself rising, drawn upward like a bubble seeking air.

His head broke the surface with barely a sound. The air was a shock, thick with the smell of salt and something else, something earthy and foreign—the scent of land. The lagoon was a secluded cup of water, sheltered by jagged black rocks. And there, anchored in the center, was a ship.

It was a hulking, dark thing, all weathered wood and tangled rope. A single lantern swung from a pole, casting a wobbly gold path across the water. And leaning against the rail was the source of the song.

A man. His clothes were rough, stained dark in places Caspian didn’t want to identify. A hat shadowed his face, but Caspian could see the glint of a ring in one ear, the corded strength of his forearms as he gripped the wood. The song ended on a gruff, trailing note.

Silence rushed back in, filled only by the lap of water against the hull.

Caspian’s heart hammered against his ribs. He should dive. Now. Disappear into the blackness below.

But then the man moved. He straightened, tilting his head as if listening to the night. He pulled a flat bottle from his belt, uncorked it with his teeth, and took a long swallow. Caspian could smell it from here—sharp, fiery, unlike the fermented kelp wines of his home.

The man sighed, a rough, tired sound. "Well, don't just hover there like a drowned ghost," he said, his voice a low gravelly thing without the song's melody. "Come on. I know you're there."

Caspian froze. Every instinct screamed at him to flee. But a deeper, more reckless part of him, the part that had been bored with the court's rituals and the same old stories, held him fast. How had the human known?

He swam forward slowly, letting the moonlight catch the sheen of his scales. He kept his distance, stopping a dozen feet from the ship. The man turned, and the lantern light fell fully on his face. He wasn't old, but his skin was weathered by sun and salt. A pale scar cut through his stubble from his lip to his chin. His eyes were the color of the deep ocean trenches—dark and unreadable.

Those eyes widened, just for a fraction of a second. A flicker of shock, quickly mastered. He didn't gasp. He didn't reach for a weapon. He just… looked.

"Well, I'll be damned," the man breathed, the words barely a whisper. He leaned further over the rail, his gaze traveling over Caspian's iridescent hair, the powerful coil of his tail, the smooth, strange planes of his torso. "The stories are true."

Caspian found his voice. It felt thin and unused in the open air. "Your song…" he began, then stopped, unsure how to explain the pull, the haunting beauty of that rough human noise.

The man grinned, a flash of white in the shadows. "That old thing? Just a shanty. Something to pass the time." He cocked his head. "You understand me?"

"Your words, yes," Caspian said. "The feeling… that was new."

A slow, calculating smile spread across the man's face. It didn't reach his eyes. "New, huh? I bet a lot of things down there are new." He rested his chin on his arms. "Name's Silas. What do they call you?"

"Caspian." The name felt like a secret, given away too easily.

"Caspian," Silas repeated, as if tasting the word. "Pretty. Fits you." He gestured with his bottle. "You want a taste? It'll put fire in your belly."

Caspian shook his head, his long blue hair swirling in the water. He watched Silas, this creature of wood and wind and rough edges. He was nothing like the stories of brutish, simple-minded surface-dwellers. There was a sharp intelligence in his gaze, a stillness that felt more dangerous than any overt threat.

"You're not afraid," Caspian stated.

Silas let out a short, harsh laugh. "Afraid? Son, I've seen sea serpents longer than this ship and storms that could suck the soul from your body. You're just about the most beautiful thing I've ever laid eyes on." He leaned closer, his voice dropping to a conspiratorial murmur. "You know what my crew would do if they saw you? They'd see a prize. A myth to be skinned and sold. They wouldn't hear your voice. They wouldn't care about your name."

The words were like a physical blow, cold and brutal. Caspian recoiled, dipping lower in the water.

"Hey, easy now," Silas said, his tone shifting to something softer, almost soothing. "I'm not them. I'm just a man who appreciates rare beauty. I'm telling you so you'll be careful." He looked around, back toward the dark shape of the ship. "It's not safe for you here. Not with them around."

The warning was laced with a strange kind of intimacy. It made Caspian feel both naive and uniquely chosen. This human was sharing a secret, trusting him with a truth about his own kind.

"Then why are you telling me this?" Caspian asked, his voice barely audible.

Silas's dark eyes held his. "Because a thing like you shouldn't be spoiled. It should be… appreciated." He pushed back from the rail. "I have to get back before I'm missed. But you should come back tomorrow. Later. When the moon is high. It'll be quieter. Safer."

He didn't wait for an answer. He turned and melted back into the shadows of the ship, leaving Caspian alone in the shimmering water, the man's warning and his invitation tangled together like seaweed in his mind. The surface world was not just forbidden; it was sharp, and it was clever, and it had just looked at him not as a monster, but as a prize. And he, Prince Caspian, who had everything the deep could offer, found himself desperately wanting to see it again.

The want was a physical ache, a hook lodged behind his ribs. He stayed there, treading water long after the man—Silas—had vanished, until the chill of the night air raised goosebumps on his skin, a sensation both alien and thrilling.

He dove.

The descent was a shock of silence, the raucous world above swallowed by the deep’s embrace. But the quiet felt different now. It felt empty. The colorful coral cities seemed muted. The playful shrieks of his cousins felt childish. His mind was filled with the grating music of that voice, the sharp tang of that air, the dark, knowing look in that human’s eyes.

They'd see a prize. A myth to be skinned and sold.

The words echoed in the water, a poison seeping into his paradise. He swam faster, his powerful tail driving him through forests of kelp that clawed at him like grasping hands. He needed to get home, to the familiar glow of the palace spires, to the reassuring weight of the deep.

But when he reached the grand, opalescent gates, he hesitated. The guards nodded, their expressions bland and dutiful. Inside, the court was a swirl of iridescent fins and murmured gossip. It was beautiful. It was suffocating.

“You are restless, my son.” The voice, like the shifting of continental plates, came from the throne. His mother, the Queen, watched him, her ancient eyes seeing too much.

“I was exploring the upper trenches,” Caspian said, the lie feeling slippery on his tongue. “The currents were strange tonight.”

She regarded him for a long moment. “The currents near the surface are always strange. They are filled with flotsam. And jetsam. Things that do not belong in our world.” She turned away, a clear dismissal. “Do not lose yourself in them.”

The warning was clear. And it only made the hook in his chest pull tighter.

The next day was an eternity. He went through the motions—overseeing the tide-pool nurseries, arbitrating a petty dispute between two octopus farmers—but his thoughts were always upward, toward that shifting mirror, toward the promise of a later hour.

When twilight finally bled into proper night, he didn’t hesitate. He shot toward the surface, a green-and-blue streak through the black water.

He broke the surface in the same secluded spot. The ship was still there, but quieter. Darker. Only a single lantern burned amidships. The moon, a sharp sliver of bone, was high.

For a long time, there was nothing. Just the water and the stars and the crushing weight of his own foolish hope. He’d been played for a fool. A surface-dweller’s cruel joke.

Then, a soft scrape of wood on wood. A small rowboat detached itself from the shadow of the ship, sliding silently toward him. Silas was at the oars, his movements efficient and quiet.

He rowed up close, so close Caspian could see the damp patch on his shirt, the fresh scratch on his knuckles. The sharp, fiery smell was on him again, stronger now.

“You came back,” Silas said, and his voice was a low, intimate thing in the vast night. He wasn’t smiling. His expression was serious, intense.

“You said it would be safer,” Caspian replied, his own voice sounding too melodic, too delicate.

“It is. For now.” Silas rested the oars, letting the boat drift. His dark eyes scanned Caspian, not with the greed he’d described in his crew, but with a deep, unnerving focus. “I’ve been thinking about you all day. A prince of the sea. It’s a hard thing to get your head around.”

“How did you know?”

“The way you carry yourself. It’s in the bones.” Silas leaned forward, his elbows on his knees. “What’s it like? Down there?”

And so Caspian spoke. He told him of the cities of light in the midnight zones, of songs that could chart a path across an ocean, of the pressure that held you like a loving embrace. He spoke more than he ever had to anyone, the words spilling out, pulled forth by the sheer, rapt attention on Silas’s face. He was being seen, truly seen, for the first time.

Silas listened, never interrupting, just nodding slowly. When Caspian finished, the human was silent for a moment, as if letting the wonder of it all settle.

“It sounds like a dream,” he said, his voice rough with something like awe. Then he sighed, a performative sound of regret. “It’s a shame.”

“A shame?”

“That a prince should be so… trapped.” Silas gestured vaguely toward the depths. “In all that grandeur. Do you ever get to make your own choices? Or are they all made for you by currents and queens?”

The question hit with the force of a tidal wave. It was exactly what Caspian had been feeling but had never named.

“I… my duties are to my people,” Caspian said, the courtly response feeling hollow.

“Duties.” Silas tasted the word and found it bitter. “I was born in a port slum. My duty was to survive. Everything I have, I took. My choices are my own.” He looked out at the dark horizon. “You have all that power, that beauty… and you’ve never even seen a sunset from a beach? Never felt real rain on your skin?” He looked back, his eyes gleaming in the lantern light. “I could show you.”

The offer hung in the air, shimmering and dangerous. It was everything the laws forbade. It was everything he suddenly, desperately craved.

“I can’t,” Caspian whispered.

“Can’t? Or have just never been given the chance?” Silas’s voice was hypnotic. “One quick look. I have a cove, not far from here. Sheltered. Private. You could see the world, just for a moment, as it is. Not as you’re told it is.”

Caspian’s heart was a frantic drum against his ribs. This was madness. This was treason.

But it was a choice. His choice.

He looked toward his world, a kingdom of boundless water that now felt like a cage. Then he looked at Silas, who offered a key.

“How?” The word was out, a breath of surrender.

A slow, genuine smile spread across Silas’s face. It transformed him, making him look younger, warmer. “That’s the spirit.” He reached under his seat and pulled out a large, coarse-woven sack, the kind used for holding grain or potatoes. It was damp and smelled of fish and earth.

“It’s not dignified, I know,” Silas said, his tone apologetic. “But it’s the only way. I’ll row you in the boat. You’ll be hidden. Safe. I’ll get you to the water in the cove, you can have your look, and I’ll bring you right back. No one will ever know.”

The sack looked like a coffin. It smelled of death and captivity. Every instinct screamed.

Prize.

But Silas’s eyes were earnest. His plan was practical. He was risking something, too.

“Trust me,” Silas said, and his voice was like the gentlest of currents.

Caspian, Prince of the Deep, made his choice. He nodded.

“Good man,” Silas murmured.

He held the sack open over the side of the boat. The opening was a dark maw. Caspian took a deep breath, the last of the free, salty air, and slid headfirst into the rough, confining darkness. The world vanished. He was curled on the damp wood of the boat floor, his tail folded awkwardly, the coarse fabric scratching his scales.

He felt the boat shift as Silas moved. Then the sound of the oars dipping into the water, the rhythmic creak as they began to row.

For a while, there was only the sound of the oars and the lapping of water against the hull. Then, another sound. A different kind of creaking. A heavier, more metallic sound. The sound of a chain being slowly, quietly drawn.

The rowing stopped.

The sack was suddenly yanked upward, the rough fabric tightening around him, lifting him from the damp floor. He was being hauled. A grunt of effort from Silas, then the rasp of rope through a pulley.

He was swinging in the air, trapped and disoriented.

The sack was dropped onto a hard, unyielding surface. Wood. Deck wood.

Footsteps approached, heavy and multiple.

“Well? Let’s have a look at our investment,” a new voice growled, coarse and unfamiliar.

The top of the sack was torn open.

Light from multiple lanterns blinded him. He blinked, his eyes struggling to adjust. Silas stood over him, but the earnest, understanding man was gone. His face was a cold, hard mask of business. Behind him stood two hulking brutes, their faces scarred, their eyes gleaming with avarice.

Silas nudged him with his boot, not hard, but with a possessiveness that made Caspian’s blood run cold.

“Told you he was real,” Silas said, his voice now flat and transactional. He looked down at Caspian, and the last vestige of warmth in his eyes was extinguished, replaced by the flat, dead sheen of a merchant assessing his goods. “Now, let’s talk about what a live merman prince is worth to the right collector.”

The words hung in the air, colder than the sea spray. Caspian stared up at Silas, but the man who had spoken of sunsets and freedom was gone. This version had flat, dead eyes, like a shark’s.

“He’s a bit… drier than I expected,” one of the brutes grunted, a mountain of a man with a nose that had been broken more than once. He prodded Caspian’s tail with a thick, filthy boot. The touch was a violation.

Caspian flinched, a helpless ripple moving through his body. The rough canvas of the sack scratched against his scales, which were already beginning to feel tight and brittle in the open air. Each breath was a rasping effort, the air itself a coarse, foreign substance scraping his gills. He tried to speak, to summon the commanding voice he used in the royal court, but all that came out was a strained, watery whisper. “You… lied.”

Silas barked a short, humorless laugh. “I offered you a new perspective. And you’ll get one. Probably from inside a glass tank in some duke’s menagerie.” He turned to the other brute, a wiry man with a face like a hatchet. “Get the crate. The reinforced one. And keep him wet. He starts looking like yesterday’s catch, his value drops quicker than an anchor.”

The hatchet-faced man scurried off. The larger brute, Brute, remained, his eyes roaming over Caspian with a detached, clinical interest. “Think he’s worth the trouble, Silas? He looks… fragile.”

“His fragility is the point,” Silas said, pulling a knife from his belt and casually cleaning his fingernails with the tip. “Rarity. Beauty. That’s what the high-born pay for. They don’t want a monster; they want a trophy. And this…” He gestured with the knife toward Caspian. “This is the ultimate trophy. A prince of a lost world.”

The word ‘trophy’ hit Caspian harder than the brute’s boot. This wasn’t an exploration; it was a taxidermist’s prelude. Panic, cold and sharp, finally pierced the haze of betrayal. He couldn’t die like this, gutted and stuffed for some land-dweller’s amusement. He had to do something. The ancient songs. The magic.

He closed his eyes, ignoring the burn of the air, and focused. He reached for the old power, the one that could charm the currents and soothe the kraken. He poured his fear, his desperation, into a single, silent note, a compulsion woven from heartbreak aimed at Silas. Let me go. See me as you did before. Remember the song.

He opened his eyes. Silas was staring right at him, a faint frown on his face. For a heart-stopping second, Caspian thought it had worked. Then Silas tilted his head and spat over the rail.

“Knock that off,” Silas said, his voice low and dangerous. “The stories say your kind can sing the stars from the sky. Try it again, and I’ll have Brute here gag you with a tarred rope. It won’t be pleasant.”

The magic sputtered and died. It had felt like a gentle wave lapping against a granite cliff. The human’s greed was a stronger shield than any magic Caspian possessed.

The hatchet-faced man returned, dragging a heavy, sodden wooden crate. It was filled with a few inches of sloshing seawater that smelled of rot and old fish. “Crate’s ready.”

“Alright, prince. Time to change accommodations,” Silas said, nodding to Brute.

The big man bent down, his pungent smell of sweat and brine overwhelming Caspian’s senses. He grabbed Caspian by the arms. The touch of the man’s calloused hands on his smooth skin was grotesque. Caspian struggled, his tail whipping against the deck with a series of dull, impotent thuds.

“Feisty,” Brute grunted, amused. He easily manhandled Caspian, lifting him with a grunt of effort and shoving him unceremoniously into the crate.

The impact jarred every bone in Caspian’s body. The water in the crate was frigid and foul, a mockery of his home. It barely covered his lower half. Splinters dug into his back and arms. The confines were so tight he couldn’t straighten his tail, the emerald scales pressing painfully against the unyielding wood.

Silas approached and looked down into the crate. His expression was unreadable. “Don’t look so betrayed. This is just business. You wanted to see the world? Well, you’re about to see a lot of the inside of a ship’s hold.” He picked up the heavy lid. “Try to breathe easy.”

Darkness slammed down as the lid was hammered into place. The world shrunk to a suffocating box of rough wood, stinking water, and the sound of his own panicked, rasping breaths. He could hear their muffled voices above the frantic beating of his own heart.

“—secure that lid. I want two men on this door at all times.”

“What about the crew? They’ll talk.”

“Let them. A legend walking the decks is better than any bonus. Keeps them in line.”

The footsteps receded.

Alone in the absolute black, Caspian pressed his hands against the lid. It didn’t budge. He was a prisoner. A commodity. The weight of his own naivety crushed him harder than the wooden walls. He had traded the endless, free ocean for a box. His mother’s warning echoed in the dark, not as a reprimand, but as a prophecy fulfilled.

Then, a new sensation. A deep, rhythmic vibration began to thrum through the wood, a metallic grinding that shook the very planks he lay on. The ship was moving. They were leaving the lagoon. Taking him farther from home with every passing second.

He curled into himself, the action cramped and painful. This was the surface world. This was the choice he had made. And in the echoing darkness, with the engine of his captivity groaning around him, Prince Caspian began to understand the true, brutal price of curiosity.
