Chapter Text
Storm was stuck. He had been stuck for years now, circling this boring tank, stuck in a lab. All the walls were the same, white and stale. Storm had once been used to the vibrant blue and colorful reefs he had adored as a pup. Yet now he was stuck. All he could think about was his mate and pups, oh how worried his sweet mate could be, along with their pups for years now. He missed them. He missed them dearly.
Though, Storm couldn’t complain. Even if he was stuck in this nightmare lab, he had his own tank. It was larger than all the others in this room, due to his large size. His tail reached a good three feet(91cm) with his body length being four(122cm). His teeth were long and sharp, a dirty yellow and unbrushed, since anytime someone would even attempt to join the siren in his tank, he would try to eat them.
He certainly wasn’t as appealing as the scientists thought he would be. They expected a beautiful male siren, pretty blue scales and a lonely boy. But life isn’t like the stories you hear about beautiful sirens and mermaids.
Instead, Storm was a rough and violent alpha siren. Expected, of course. But his ability didn’t even work. Usually, the scientists saw the sirens they held as the object of their desires. Sometimes their crushes or a lost loved one, but Storm? Storm was a big, ugly creature that was terrifyingly strong and determined to escape.
The siren was born an outsider. His mother an outcast for a mermaid to have a child with a siren and his father long gone. His mother raised him close, they swam the ocean in search of a home, but never found one. Storm’s mother passed quickly and Storm was left to fend for his own.
Storm was older, swimming the ocean in search of dinner. He hadn’t eaten much lately, as he had been seeing boats around. He knew he shouldn’t be too close to the surface as his mother raised him not to, but he couldn’t really care.
Soon enough, Storm heard a soft cry from far away. He paused, his long, blue tail slowly falling below him as he listened. Another cry. By now he was just curious, just for fun.
Storm followed the sound, finding a mer stuck in a human’s net.
He chuckled, this was one of the stupidest things he’d ever seen. I mean, really. How could someone ever be stupid enough to get stuck in a human’s net! It was absurd to him!
“Well, well~” Storm purred, moving closer to the mer stuck in the net. The mer spun around at the sound of a voice, his eyes widening at the sight of the big siren.
“What have we, hm? A little mer stuck in a human’s net? Are you an idiot?”
The mer sputtered back at Storm, scrambling to defend himself. “I-I am not an idiot! This net came out of nowhere, n-nowhere I tell you!” he scowled at the siren before him. “Get away now! I’ll call my pod and report you!”
Storm rolled his eyes. This guy was kinda cute. “Are you going to keep squabbling like a flustered fag?” he teased, his eyes sparkling.
This seemed to startle the merman before him
“I-I am not a flustered.. Oh! Shut up you lousy siren! You’re going to kill me anyways, aren’t you! Don’t you know the term, never play with your food? Hasn’t your mother raised you properly!?” the merman spat back, getting riled up in the tight net around him.
Storm had to admit, he was getting turned on. With how tight the net was, highlighting the merman’s features. His thin waist and wide hips were a good show. His scales a vibrant orange and fins soft, waving softly in the ocean current. His eyes were sharp, a disgusted look drawn on his face. It was adorable. Storm wanted to have the mer moaning under him, getting his brains fucked out. God the cute pups this mer would give him..
Storm shook his head, needing to stop fantasizing about a cute merman being a bitch to him. Really, why did he always like the ones who hated him? Was that a sign of a red flag? He wasn’t sure.. Nor really cared.
Suddenly, the net between them slashes open, the mer stared at Storm in shock and surprise, the net tearing and falling deep to the sea floor. Storm floated there indifferently, watching the merman to see what he would do. Run off, maybe? Or stay and thank the siren for freeing him.
As Storm expected, the merman stumbled for a bit, perhaps trying to figure out if he would thank the siren or not, before scrambling away.
Storm scoffed. “Coward..” and looked back to the net. The boat above wasn’t moving, so Storm decided to investigate.
Storm climbed up onto the ship, finding a sleeping human. He grinned, licking his lips and lugging his large body across the ship. He slipped a wet, webbed hand over the human’s mouth before taking a bite.
The human shot up, screaming in immense pain as the siren ate him alive. The fisherman looked down, finding a large blue creature with a fish tail tearing into his arms, his eyes almost hypnotizing, it was hard to look away.
By the time Storm was full after not eating in a week and trying to fill himself, it had been an hour or so. The sun was setting and orange rays cast down across him. The siren yawned, his large teeth showing as he curled up in the ship for some sleep.
Storm was startled back awake by the boat rocking. He lifted his head, blinking his eyes and adjusting to the darkness. It was night now, moon high in the sky. He must have been asleep for a good few hours.
A small squeak caught Storm’s attention, he directed it towards the other end of the ship where he saw a figure of another mer there. Most likely terrified at the sight of a bloody siren waking with a dead, bloody human with torn skin and muscles behind him awakening.
Storm recognised it as the mer from earlier, his orange scales reflecting in the small light on the side of the ship. He watched the orange merman, waiting for his move.
The merman whimpered, scared by the sight of a terrifying siren with a dead body behind him he had been chowing down on. Though, Storm’s thoughts were swept away by the rushing scent of an omega in heat. That’s why the merman had returned. To find the alpha siren who had helped him, even if he had called him a slur.
Storm looked at the merman, his eyes flickering back and forth between the merman’s and his smooth body. His tail flicked, slapping against the floor of the ship. It startled the merman, but he shivered, finding it attractive in a way and inched closer to the alpha.
Storm continued to watch the merman, curious about him. The merman kept inching closer, meaning his sweet scent was getting closer and stronger. It was as if the roles were reversed, Storm was slightly entranced by the omega’s scent while the merman was trying to draw the siren in.
Though, the siren’s brain couldn’t handle it for much longer. He growled softly, making the merman pause, only feet away from the siren. The merman moaned softly at the smell of the alpha’s scent and that’s all it took for the siren to pounce on him.
Storm pinned the omega merman down to the ship floor, looking at him and shoving his face into the merman’s neck, taking in his scent right at his glands. The orange merman moaned again, his tail wrapping around the siren’s longer one and clinging onto him.
“A-ah, please..” he begged, not sure what for. “It’s so hot..”
Storm seemed pleased at his begging, his long tongue slipping out and running over the merman’s scent gland, drawing out more pleased sounds from him. “You’re so easy to please.” he chuckled, a smirk on his face, proud of himself. “What’s your name?”
“Ca-uh-Casper..” The merman said, interrupted by another lick along his gland from the siren.
Storm purred at his name. ‘cute’ he thought, because of course he did. He could feel the merman under him, squirming and rubbing his tail against the siren’s, his heat open and ready. By the Moon, this was too cute.
Storm leaned down and kissed the merman, his tongue easily and quickly sliding into the vocal merman’s mouth and devouring him as he removed himself from his slit and poked against the merman’s own slit.
Storm managed to push himself inside without needing his fingers, and hell was it tight. He groaned, his lips parting from the merman’s as he focused on kneading himself inside.
Casper below him was a mess. Moaning, screaming and squirming. Storm just had to guess and say he was getting the job done.
Soon enough, Storm got too affected by the pheromones from the omega and began to properly fuck him the best be could. Their lips together, mouths open.. His hips moving and fucking the daylights out of the poor merman.
It took a while for the two to break apart. They had soon moved down to a small cave found below the ship. Casper had built a nest for himself while Storm passed out on the rock floor, dead asleep. Though, the siren did wake to watch the merman make his nest and settle down in it. Storm lay curled in a ball, tail covering most of his face except his eyes so he could watch comfortably.
Casper looked over at the siren, a small whine coming from him as he snuggled into the nest, wanting the siren to join him. Storm fell weak to the merman and slithered over to the nest, eventually curling up around the merman and falling back asleep. And for once in his life, he felt warmth.
