(Mass TF, Primarina TF)

“Lucy! Your friends keep calling, are you going with them or not?”

“Yes, Nance,” Lucy Gainor called back, unable to keep the hint of irritation from her voice. She knew that her mother hated being called by her name, just as her mother knew Lucy hated being called her own.

It wasn’t that the name was bad. If anything, it was rather cute and melodic. But that didn’t sit right with Lucy. She’d always been a rougher girl, as if living her life in spite of her parent’s plans.

Lucy kicked off from the tree she’d been perched in, curling up for a somersault landing. Then the voice distracted her.

It was beautiful, a siren’s melody that crept into her ears and hugged her brain tight. There were harder sounds, like words behind it. ‘Mare’ or ‘Marin,’ perhaps. Lucy didn’t have time to fully process them before the ground rushed up to meet her.

Luckily, it was just dirt, not the hard cement of the nearby pool in her backyard. Unluckily, it was also damp from the recent rain, and she ended up with a forehead full of mud for her efforts. It should have infuriated her, but the echoes of that melody still swam about her thoughts.

For a moment, she tried to focus, to snatch a little more of that melody. But it was gone, just a fleeting, sweet memory in her head.

“Lucy!”

And said memory wasn’t helped by the shrill cries of her harpy mother. Lucy sighed, wiping at her forehead with a scowl, then looking to the pool with a quiet smirk.

Of course, her mother had railed on for the next few minutes about how Lucy would need to clean the pool later, and take better care of her hair, and do the chores, and any number of trivial things. Lucy heard it all but didn’t listen to a word. She soundlessly drifted to her car, slamming the door and setting her way towards the beach.

Everything was a blur, because the moment Lucy had submerged her head, the song had returned. She’d kept her head beneath the water for so long her lungs burned, only pulling herself free by instinct. For a moment, she’d considered her reflection.

Blonde, tousled hair, brown eyes, a hint of a tan… Yet it all looked so wrong. She couldn’t quite place why, not until she caught sight of her reflection.

There was a streak of blue in her hair now, as though she’d dyed it. Was that what her mother had been yelling about? She shouldn’t have. The blue looked nice. Welcome, even. Lucy twirled a finger around it, humming an echo of the song.

Her voice was a little rough for it, so she cleared her throat and tried again. That time it came out a little smoother. She smiled. The tune was well in her head now, though the words stubbornly drifted in and out, like the tide.

“Mary… Nah, pree…” She couldn’t get them to sound quite right, and chewed at her lip thoughtfully. She looked to her reflection for guidance, but met only her confused blue eyes. Something seemed wrong. She tried to focus on it, then realized someone was rapping their knuckles against her window.

“Hey, Lu! You in there?”

Her head swam. Lu… No, that was too short. Lucina sounded better. Closer to the song. Lucina nodded to herself with a smile before angling her head towards the speaker. It was one of her friends, but weren’t they supposed to meet at the beach?

Lucina opened her mouth to ask, and flinched as it interrupted her humming. Her vision swam a little, and she caught better sight of her surroundings. She’d somehow driven to the parking lot, weird.

“Hey, Courtney. You OK?” Lucina fumbled her door open, stumbling a little when she went to stand. Her legs must have fallen a little asleep when she’d been driving.

Courtney caught her with a raucous laugh. “I’m not the one who should be asking that. Were you pregaming before you got in the car? Hardcore!”

Lucina smiled unsurely. “Pregaming?” The word was so familiar, and she struggled to place it.

“Dude, hook me up when you get home. For now, let’s hit the surf while there’s still light out.”

Surf. That word was familiar. Lucina liked that word. Her eyes lit up and she clapped eagerly. “Abthowutewy!”

Her tongue felt funny, and it made her slur her words. Courtney didn’t seem to mind, so Lucina didn’t let it distract her. She could already smell the ocean. It felt wonderful. Her nose twitched as she drank deeper of the salty spray, imagining she could taste the sunlight.

She was aware that Courtney was giving her a funny look, but then she started to hum her happy song, and Courtney wobbled a bit in place, following along. That was fine, better than fine. She could hear her friend humming a little bit too, trying to follow the beat.

There were three more humans waiting for them, two girls and a guy. They said something, somethings.

“Are you okay?”
“What’s wrong with your nose?”
“Look at her hands, they’re swollen!”
“Hey, get a lifeguard or something!”
“Is she high?”

She didn’t listen to them, not when the song was so pure, the ocean was so close. She could feel it against her toes. The male’s hands tried to grab at her and she broke free of them with a chirped “Marina!”

Then she splashed into the water, and everything went from that sunny haze to a clear, focused underwater view.

Lumarina wasn’t human. Not anymore. She could see in her hands, in her feet, in her very peripheral vision. She gasped, tasting delicious salty water, breathing it in like air. That wasn’t right either. Was it?

It was like she was just waking from a vivid dream, or perhaps slipping into one. Lumarina knew that her legs should be separate- that she should have legs to begin with. But as they clamped together, skin fusing together seamlessly, she couldn’t deny that it felt right to have a long, thick, powerful tail.

Her thighs plumped pleasingly, and she rubbed her swollen fingers against them. They were slick and squishy to the touch, almost like when she’d gone to a petting zoo and rubbed a seal’s tubby belly. Lumarina then caught sight of her hands. Her eyes widened, and she sang out another underwater scream.

Her fingers were fatter, thicker, merging into each other. It was like she had a permanent pair of flippers attached to her wrists. Or… Maybe fins would be more accurate. She brushed them against her swimsuit, as thought that would do anything to separate her fingers.

The only thing that managed was to somehow dislodge her lycra one-piece.

‘Somehow.’ Now that she was focusing more on it, there was a very good reason: it wasn’t meant to fit her. Her tail had shorn through the bottom of her swimsuit, and her torso had thinned so much that the top didn’t fit. A frilled, webbed mane had pushed the shoulder straps easily off her pale skin, and a similar frill along her waistline had was further stretching her swimsuit.

Lumarina looked like some kind of monster. And she wasn’t alone. Another shape splashed into the water, one with Courtney’s wild bushy hair. That was all that was left of her friend. The girl’s body was near-identical to Lunamarina’s own.

She had pale white skin, blue frills along her shoulder and waistline, and a deep blue aquatic tail. Her face had stretched into a muzzle tipped with a round pink nose. She was like some mix of a mermaid and a cartoonish seal. Bubbles spilled from the Courtney-monster’s mouth as she tried to say something.

Lumarina thrashed her tail, gasping again. All the air had left her own lungs, and not even a bubble slipped out of her throat. It was a shame, because those bubbles were the only thing muffling the sound of her new voice.

Just the gasp alone was angelic. Perfect, even. Her panic stilled. Her eyes glazed. She could perfectly her melody echoing in the vast ocean. And hear the echo of her song as her fellow Primarina found her sea-voice.

Primarina. That was the song. Of course. She curled her powerful body, kicking her tailfin and surging towards the surface.

The three humans were still at the edge, a little addled. Of course they were, they’d just heard the hums of the other Primarina’s song. But to hear the real thing…

Primarina licked her lips, then pressed a fin against her soft blubbery chest. “Primarina, Prima Rinapri~”

She didn’t need to sing it loudly. Even humming it alone would have been sufficient. But that didn’t sit well with her. She wanted to sing louder, as loud as possible. So she let out as loud of a cry as possible, one that she was sure would echo through the beach.

The male human simply popped, a cloud of sand obscuring his body for a moment. When it cleared, it revealed a confused, buxom Primarina. She put her fins against the sides of her head, babbling insensately for a moment as her brain struggled to catch up with her reprogrammed mind. Then, her eyes brightened with a swirl of blue and pink, and she joined in the song.

The women fell against each other, pressing their deforming bodies against each other. Their tongues flopped form their mouths, and they shamelessly drooled and slobbered onto each others’ chests. Primarina was envious of them, so she looked to her former friend, current packmate in the water and beckoned her closer.

Unfortunately, her new sister was a bit of an idiot. Primarina rolled her eyes as her sister dopily pawed at her massive chest. It looked like she was more intent on using her chest as a makeshift flotation device, rather than singing properly.

Not that that mattered much, given that Primarina was perfectly fine singing on her own. Still, she couldn’t help but notice that her two changing sisters on the shore looked just as dimwitted as the first sibling she’d made.

Maybe she was the only one supposed to have any smarts? Or… As close to ‘smarts’ as a Primarina could have. After all, she herself was a bit waterlogged between her ears. Certainly nobody with any intelligence would do what she did next.

Primarina splashed her powerful tail fin, surging towards her first sister with a dopey smile on her face. She eagerly grabbed the other Pokemon’s face, shoving it between her chest and humming happily.

It was exactly as fun as she expected. She hummed a little more before hearing an odd echo. Her head tilted, and she looked over back to the beach to see her three new sisters all singing her melody. They weren’t alone.

‘Pandemonium’ wasn’t a word in her vocabulary, mostly because Primarina would lose track after ‘Panda’ and begin singing about big, fat, fluffy cuddle bears. But if it was, she’d have known exactly how to describe what she was seeing.

Up and down along the coast, more Primarinas were joining in on the song. A swimmer had beached herself, and was crawling along the sand, newfound fins digging furrows as she cried out helpless notes of music. It looked like she hadn’t yet fully gotten the ability to sing underwater, but that would change.

A little past her, a pair on beach towels had gone from cuddling to their new chorus, singing in each other’s faces as they pressed their soft bodies against each other. It looked like they were enjoying this, as their fins explored more and more of their bodies.

Just behind them, a sleeping woman was snoring out to the tune of the song, her tongue lolled out from her growing muzzle. Her nose twitched a little, but there was no sign that she’d wake anytime soon, even though her tail was currently thumping against the warm sand contentedly.

Primarina’s eyes sparkled at how pretty it all was, and she chirped with joy at how many sisters she’d soon have. They were all calling to her, and she sang back, eager to find more and more friends to play with.
