Last week, it was “Greek Gods of the Sea.” Togas and tridents, mostly, some seashell bikinis, a few fake beards stuffed with plastic starfish. They drank too much and cranked the music too loud, but that’s nothing new. Everyone knows what to expect from the Lucky Rock Pier Party People Association (“Lurpppa” to the local news, “Trouble at Ten O’Clock” to your fellow boardwalk employees, “Those Fucking Kids” to beachfront property owners).
You wear headphones most nights anyway, desperate to keep the shrill, repetitive carnival songs of the pier funhouse from being seared into your brain. They don’t bother you much because the sign at the front says there’s no bathroom and all the hot dogs and funnel cakes are further down the boardwalk, but a few will trickle in just for something to do. If they spot the freezer, they’ll huddle around the glass and stare like the Mona Lisa’s in there, agonizing over a choice between an ice cream sandwich or fruit pops.
Tonight, it’s a glow party. Neon beach balls and glow stick arches. You can’t hear the noise they’re making through your headphones but you can feel the bass throbbing through your feet. Someone’s probably going to call the cops again. The tourist family population retreats this time of night so it’s just you, the handful of shops still open this late, and Trouble at Ten O’Clock. This one’s more fun to watch, at least, bright and colorful like the spill of noctiluca. They’re vivid in glow-in-the-dark body paint, covered in luminescent stripes, swirls and splatters.
A few of them come stumbling up the pier earlier than usual. Three women in different halter tops, painted with matching curly cues and butterflies on their faces. One of them wanders off to look at the tote bags. Another, much more inebriated, leans heavily against her friend. The designated driver, you assume, who drags her to the freezer to pick out something to eat. You glance down at the beach and see one of them sitting on Lucky Rock, the jagged chunk of stone sticking out of the water not far from shore. You’re not sure how he climbed up the slippery, steep sides but he’s definitely not supposed to be up there. The people on the beach are way too excited about it, gathered around cheering and hollering.
Three ice cream sandwiches are dropped on the counter in front of you. You lift one side of your headphones and shrieking noise rushes in, the glow party just as raucous as you expected. “Will that be all?” you ask. The woman nods. Her friend starts to fall over and she has to support her weight against her shoulder. You ring up the total and she groans. Everything on the boardwalk is three times the price it should be, but she adds a tote bag when the other woman wanders back with one and tosses their ice cream inside. “Thanks, come again,” you call, sliding your headphones back on.
Ten minutes until closing time. Not much to do but sweep out the sand gathered in the doorway and tidy up the disaster zone a horde of children made of the stuffed animal section. Sharks and dolphins on the top shelf, turtles on the second, fish and starfish on the third—
Something moves in the corner of your eye. Startled, you turn and find a man ambling slowly through the store. A stray from the glow party, you think at first. Then you look again, paying attention this time. He looks like all the partygoers down on the beach, a silhouette with luminescent edges, but he shouldn’t. Not under the store lights. He’s midnight blue from head to toe beneath intricate glowing patterns, chest and shoulders speckled with small dots like cyan freckles with larger spots along his sides. Thin stripes trace the outlines of muscle beneath the skin, turning into a spiral pattern at his hips.
Which you can see, you realize, because he’s naked. No swim trunks. No speedo. He’s wet and dripping all over the floor like he just crawled out of the water, a puddle slowly growing beneath his feet, and you can follow the course of every droplet as they roll slowly down curves and valleys of lithe swimmer’s muscles. Some of the lines on his torso are moving, you realize. Horizontal squiggles on either side of his abdomen flinch and pulsate.
Gills, you realize. The pieces come together all at once in your mind. Despite working the boardwalk as long as you have, you’ve never seen a sea muse before. Most people haven’t. They’re skittish, you’ve heard. They prefer quiet coves and grottos, places humans have a harder time reaching. Safer that way if they decide to shed their tail and sun themselves for a while. This one certainly doesn’t seem bothered by the commotion down at the beach, poking through the t-shirt rack with long, clawed fingers. He doesn’t look much like the pictures you’ve seen, either, but all the pictures are of muses lurking in tropical reefs, big-finned and colorful like bettas. Beautiful like him, but not bioluminescent and not quite so large. He must come from deeper, colder waters.
You set down a stuffed octopus as gently as you can but he hears it, turning swiftly to face you. Your heart races. He has the large, eerie eyes of an abyssal creature, glowing half-moons gleaming underneath wide silver irises and black sclera. Nobody prepared you for what to do in this situation. Do you play dead? Raise your arms and make noise to scare him off? What you mistook for slicked back hair is some kind of shimmery membrane. It flares out like the neck flap of a cobra in a threat display, but it starts to sag and flatten the longer you stare at each other. His eyes move slightly in their wide sockets, looking you over head to toe.
An uncannily human smile spreads across his face. He makes some odd gestures towards you. His mouth moves. He’s talking, you realize, trying to communicate. You almost lift your headphones off but your brain catches up at the last second. You don’t know a lot about sea muses but you know enough to keep your ears covered.
He blinks, staring at you in almost comical wide-eyed confusion. Then he smirks, his gills fluttering with laughter. He starts pacing back and forth, slowly inching closer like a shark circling prey in the water. He’s between you and the door so you inch towards the register counter instead. Maybe you can slip out the back?
He stops suddenly, leaving some distance between you. He speaks again, tapping the side of his head and pointing at you. You shake your head and he frowns, but he doesn’t give up. You watch, morbid curiosity overpowering your fear, as he starts to move in a slow, seductive manner. It’s some kind of dance, you think, arching his back and extending the membrane on his head again, bioluminescence glittering on thin, translucent flesh. He holds your gaze as he runs a hand down the center of his chest, over his stomach, down to his pelvis and—
You’re not entirely sure what you expected to see between his legs, but it’s still a bit of a shock. The thick, jutting member is deep indigo at the base and a lighter aquamarine down the length. It barely resembles a human cock except in its vaguely phallic silhouette, oozing from an engorged sheath that dribbles cloudy slime. The shaft is smooth with a gentle upward curve, thick and shuddering with unnatural flexibility. It narrows to a soft triangular tip. Two additional appendages unfold from his hips. They remind you of crustacean legs, rigid and insectoid. They bend along two joints, pawing at the air with their sharp claw tips.
The sea muse makes a thrusting motion. The tentacle-cock wraps around his hand, drooling like a tongue. His bioluminescent patches flash and dim like a flickering candle. You’re no marine biologist but it feels safe to assume this is a mating display.
“Uh. No? No thanks,” you say.
He grins. You see a row of daggers for teeth. He speaks slowly and your heart skips a beat when you clearly read the words, Are you sure? on his lips.
“I’m sure. Thanks anyway.” Maybe you should be flattered. You’ve never heard of anyone getting hit on by a sea muse. He lets out a big, disappointed sigh, extra dramatic so you can’t miss it, and gives himself one last stroke before he moves on. You half-expect the cock to slither back into its sheath, but it stays obscenely hard and straining upright between his legs.
To your dismay, he doesn’t leave but instead pokes around the shop some more. He wanders to the left, examining surfboard keychains and hibiscus shot glasses. He wanders to the right, squinting at the postcards. Eventually, he makes his way to the freezer and slides it open with some difficulty. His head membrane flares out wider than you’ve ever seen it the first time he sticks his hand inside. You wonder if he hissed. He tries again, pinching a fruit pop in its colorful package between his claws. He rips the plastic open.
“Hey!” you say. “You can’t just—”
He looks back over his shoulder at you, eyes narrowed and membrane spread in warning. You turn away and continue to mind your own business.
The glow party seems to be winding down. The beach balls are all sitting in a pile. Some of the glow stick arches have toppled over. The pounding bass isn’t shaking the pier anymore. You see a lot of people lounging in the sand, rolling around, stretched out together, a bunch of them writhing—
Oh, you think. That’s bold, even for Trouble at Ten O’Clock. There’s no mistaking those thrusting, grinding, back and forth movements for anything else. There are a few couples scattered around but most of them have settled into a spot worryingly close to the water, seafoam rushing around them whenever the waves come surging up the beach. They tangle together in passionate motion, kissing and caressing and fucking like it’s the last night of their lives.
Something about it unsettles you. They’re being so rough with each other. This isn’t a slow, sensual orgy but a frenzy. Mindless, animalistic rutting and forceful movements. You see mouths open in silent screams. Some of them aren’t moving. Some of them are trying to crawl away but they’re being dragged back by the ankle, the hair, the arm, pulled through the dark sand. Why is the sand so dark? And wet, glistening where the tide hasn’t risen yet.
The horrific realization grips you slowly. You’re in denial. You must be having a nightmare. A man tries to claw his way up the beach but someone else pins him down, straddles his back. You don’t see what happens, can’t make it out in the dark, but the paint on his body stretches and splits, and the sand darkens in a liquid motion under him. A woman arches her back in the throes of ecstasy, surrounded on all sides by eager, thrusting bodies. They’re biting her, you realize. Their heads lower and blood splashes the sand. Through all of it, she squirms and rakes her fingers through the sound as though she’s never felt pleasure like this before. Someone crawls between her legs and she opens them eagerly, loops them around the waist of something that is not human, you realize. None of the ones surrounding her are. They glow more brightly in more precise patterns, membranes pulsating, gills fluttering.
Your headphones are ripped away, clattering uselessly to the floor. You hear an awful cacophony of moaning, screaming, begging, and weeping. You think, for just a second, about running. Your muscles tense and your heart races. Where? For how long? You don’t know but you’re willing to try.
“Where are you going?” says the sea muse and you can’t move a muscle. His voice is low and melodic. You hear the ocean when he speaks; the hiss and splash of the shallows, the heavy drone of the deep. “Hm? Do you want to join them?” You hear the wet slap of his footsteps for the first time as he comes closer. His hand grasps your chin lightly, barely applying any pressure, but you feel compelled to turn around. To look up at his sharp-toothed smile and the gentle pulse of his bioluminescence. “My shiver is down there. Frenzying,” he says. He turns your head to the side, just far enough to glimpse the gruesome scene on the beach, then returns your gaze to him.
“Please don’t,” you say hoarsely, your throat constricted. “Don’t make me, don’t—”
“It’s been so long,” he says, and your mouth snaps shut. “Since I last came ashore.” He walks backwards, his fingers still ghosting against your chin, and you follow. You don’t want to but your legs move on their own. His voice is addictive. You hang on every word and you hope he never stops talking. The silence between makes you tremble. “Even longer since I last mated. You can see it. You can tell how long I’ve waited, if you look.”
You don’t want to look but your eyes betray you, gaze lowering to the slithering thing between his legs. It curls around itself impatiently like a snake. Another glob of slime slides slowly from its sheath and dribbles on the floor. The way it moves frightens you, the base twitching and undulating, slug-like.
“You want this,” he says. He takes another step back and you rush forward. He strokes beneath your chin.
You shake your head desperately. Your mouth is trying to shape the word “yes.”
“You do. You want this.” His back hits the register counter and he leans against it, spreading his legs wide. “You want to taste me,” he says, his voice dipping lower.
You drop to your knees so fast it hurts, feeling the blooming sting of new bruises. It doesn’t matter that you’re terrified. It doesn’t matter that the thing bobbing in your face is like nothing you’ve ever seen before. You open your mouth and suck the strange, pointed head without hesitation. The sea muse moans and your thighs quiver, inner muscles clenching on nothing. You have to hear it again.
“You need it,” he purrs, thrusting shallowly. You bob your head, taking him deeper every time. He hits the back of your throat quickly, his cock eager and probing at the inside of your mouth. “You need me to spill inside you. You need everything I have to give.” You moan and choke around his length. His hand rests on the back of your head, forcing you down further. His thrusts get harder and faster, crushing your nose against his slick abdomen.
Some part of you is screaming at the alien movements of his cock, how it nudges and prods and tries to snake down your throat, but you can’t focus on that. He doesn’t let you. Every grunt and moan, every hiss of praise, makes the fear even more distant.
“You need—oh, yes,” he groans, clutching your head with both hands as he pounds into your mouth. “You need to mate with me. You need—mm, suck on me, suck on the tip—fuck, you need my milt. I have so much and you need all of it.”
You make a humiliating, needy sound when he suddenly pulls you off of his cock. It slips out of your mouth reluctantly, the tip sliding back and forth against your lips. He drags you to your feet by the forearm, shoving you against the register counter. He bends you over it, tearing at your clothes with his claws. You cum when he blows softly against your ear. You’re still shivering, clawing mindlessly at the counter when he kisses and licks the shell, sliding his tongue into every little dip and groove.
“Do you want me?” he whispers. You hear a slick sound, a grunt, and then his hand is at your entrance. He uses the pads of his fingers but he’s not very careful. His claws prick your thighs as ass while he smears thick, warm globs between your legs. “Hm? Do you want me?”
“Yes,” you sob. You arch your back and try to press your hips back against him. He makes a growling sound against your ear that makes your knees buckle, nipping the lobe playfully.
“You want to be fucked?” One hand reaches around and roughly works your sex, spreading a warm, tingling sensation. “Want to be filled with milt?”
“Yes!”
His cock slides along the curve of your ass, teasing you. Then it slithers down, sliding into just the right angle with the tip pushed against your entrance. “Good human,” he purrs, and your eyes roll back in your head. His tip presses inside and then he’s thrusting hard and fast without warning. More slime drips from his sheath and slides down his length, the tingling slickness easing his punishing rhythm. It wouldn’t matter if the lubrication wasn’t there. You can’t do anything but lay there and gasp and meet his thrusts, needing his cock inside you more than you need to breathe.
Those sharp, grasping appendages hook around your thighs. You feel them lock into place, their grip tightening until you’re right up against the sea muse’s body. His thrusts don’t slow at all. If anything, he’s even rougher and faster, deep humping thrusts that make you tremble and scream. He keeps talking through all of it no matter how winded and breathless he gets, keeping you right on the precipice of orgasm after orgasm with filthy whispers and wet, open-mouthed kisses against your ear.
“So tight,” he hisses. “You feel so good, squeezing me like that. You want it so much. I’m going to give you everything. You’re going to be so fucking full.” His hips stutter, losing rhythm. You cum again just as a rush of warm wetness pulses inside you, spurting every time the sea muse thrusts. Thick, creamy liquid churns and foams at your entrance, a trickle dribbling down your thigh. You hear a few drops hit the floor under you. The sea muse rides out his orgasm with long, loud moans that send you over the edge again and again. He crushes you against the counter, hips rolling. One last, slow thrust fills you with another hot gush of his strange cum.
He breathes heavily. His hips sway while he’s still sheathed inside you and his cock curls just the right way to make you sob for mercy. “Hm? You think we’re done?” he murmurs. “I told you. It’s been a long time. I still have so much more to give you. And you want it, don’t you? You need it?”
“Yes,” you say, your voice quivering and broken. The sea muse starts to fuck you again and all you can do is let him.
You don’t know when it ends. It could be minutes, or hours, or days. The passage of time is measured in breaths and heartbeats and orgasm after orgasm. The floor is slick and sticky under you, a white puddle of milt steadily growing. You think he bites you but you don’t know. It all feels good, especially when he tells you how perfect you are, how sweet and submissive, how well you’re milking his cock of everything he’s saved for this moment. He makes you ride him once, seated on the counter while he bounces you in his lap. He digs his claws into the meat of your ass and leaves marks.
You don’t know who finds you. Someone else who works the pier, probably, too horrified and embarrassed for both of you to stick around. The Coast Guard sweeps the water but the sea muses are long gone, leaving nothing behind but the mangled leftovers of their frenzy. The bodies glisten in the sand, torn to shreds like a burst whale carcass. By sunrise, the flies and the seagulls are swarming. You’re escorted to an ambulance with a blanket over your shoulders. The first person to look you in the eyes tells you, very quietly, that you might want to quit your job and consider moving inland.
“Those are mating marks,” he says. You don’t know how he can possibly tell, given that they’re everywhere. Jagged, oozing circles dot your shoulders, arms, thighs and back. “Because they’re at a very precise depth. Meant to scar, not to kill. That means it’s going to come back.” They tell you not to look at the water but you do, one last time, before you leave. You don’t see anything. That doesn’t mean anything. The water’s deep and it seems to go on forever.
That night, in a hospital bed, you have a dream of someone singing to you. It sounds like the ocean filling your ears.
