There isn‘t much that Keith Kogane is afraid of.
He‘s long gotten over his fear of being alone. It‘s hard to be scared of something you‘re confronted with on a daily basis.
He‘s not particularly afraid of failure either, seeing as he‘s a natural at most things he tries. The only problems he‘s ever had in school and at work were disciplinary issues.
The fear of losing something you love is easy to avoid: You just don‘t get attached.
That would leave his own death.
He used to be scared of it as a child. But over the years, the thought has become a source of solace for him. It‘s his way out. His emergency exit, if you will.
It‘s a miracle that he didn‘t already go through with it in middle school, really. He almost did it a few times but what had stopped him was always hope. Silly, naive little Keith had still hoped for his life to improve. He thought, maybe, in the future, he‘d find a passion, a lover, a family. But life had always found a way to crush his hopes and dreams.
Now, at 25, after years of heartbreak and abandonment, he understands that hope can only disappoint him.
He‘s not scared of hurting his loved ones either. After all, there‘s no one to hurt if there‘s no one to love.
Keith simply has nothing to live for.
He could keep working at his job, hustle for raises, climb the career ladder. Or he could take out a loan and go to college. Get a “proper education“ after all.
But what‘s the point of knowledge or money when you can‘t use either to enjoy life? What‘s the point of working towards something when the only thing that keeps you going is knowing that you could take matters into your own hands and end your life whenever you want?
And so Keith
does
take matters into his own hands.
He spends a long time pondering the best method to die.
It certainly isn’t with a gun to his head or a cocktail of pills, leaving the possibility of waking up in a hospital immobilized and dependent on others forever.
He‘s not going to jump in front of a train either, or slit his wrists. There are more dignifying ways to go and he doesn‘t want to expose his neighbors to the smell of his rotting corpse growing stronger and stronger each day until it gets unbearable.
No, he knows the perfect way for him to die.
He remembers the first time his dad told him about sirens. It was a warning.
He was supposed to avoid large bodies of water, only go swimming on official and supervised beaches, never go alone and
especially
never at night!
On his last day alive, Keith wears a smile on his face.
He takes a nice long shower, making sure to scrub and shave himself thoroughly.
He goes out for breakfast and leaves the café with a coffee to go.
He drives down to the beach and parks his car with everyone else‘s. But instead of joining the other people, he starts walking. At first along a path. Later, when the path stops, over sand and pebbles.
He walks for about an hour until he finds a nice spot. There‘s no humans here, no ear piercing screams of children, no gawking eyes of adults and, most importantly, no supervision. Which means this beach is absolutely not safe and no human should ever step foot into these waters.
The perfect spot.
Keith sits down on a rock and breathes in deeply. He can‘t remember ever feeling so relaxed.
He sits there for hours, watching the waves as he thinks back on his life. He thinks of the good parts more than the bad parts. He wants them to be remembered one last time. Wants his dad to be remembered one last time.
He sits there until the sun sets and then some more.
When he is just about to get up and step into the water, he sees a shadow dart past him.
The waves caress his ankles, deceptively gently and he wades deeper.
He can see the shadow get closer and when the water touches his waist, a head pops out a foot away from him.
A small gasp tears itself from Keith‘s mouth upon the stunning sight.
The creature is as beautiful as legends describe it, perhaps even more.
Its glowing brown skin still sparkles in the fading light of dawn, its eyes a piercing, inhuman blue.
Freckles are dusted over cheeks that somehow appear soft and sharp at once. A pair of plump,
kissable
lips turn into a smirk before the creature speaks up: “What is a human doing out here at this time, all alone? And such a pretty one at that?“
The angelic voice sends a shiver down Keith‘s spine and he has to restrain himself from walking closer and just throwing himself at the beast.
It‘s not like he has anything to lose but he came here with the goal of having one last unique and unforgettable night. Even if by morning, it will be gone forever, alongside all of Keith‘s memories.
“I came here for you,“ Keith answers. “I wanted to find a siren.“
The creature cocks his head to the side and scrunches up his expressive brows. Within a second though, his demeanor changes and he puts on a dazzling smile.
Keith can‘t help but notice the sharp fangs protruding from the siren‘s mouth. Fangs evolved to hunt, to kill. In spite of that - or maybe even
because
of that, he can feel something stir in his stomach. It isn‘t fear.
This time he doesn‘t stop himself from stepping closer.
“Eager, are we?“ the siren coos, before closing the gap and surfacing more of his body so they can see eye to eye.
Keith‘s gaze is pulled down toward the now exposed part of his chest. They are close enough that he can see the defined muscles of the siren‘s stomach under the surface. When he looks up again, his eyes linger on those lips.
Keith shivers again. He has never felt such a strong attraction towards anyone before.
He must be under some kind of spell but he welcomes it.
He doesn’t flinch when the siren suddenly wraps his tail around Keith‘s legs and he loses balance.
“What‘s your name, sweetie?“ the enchanting creature asks, making sure to keep Keith‘s head above the surface while he twirls him around.
A laugh escapes the human and he clings to the siren‘s broad shoulders before answering the question.
“Keith“, repeats the siren before humming in thought. Then he adds: “My name is too complicated for you to learn on such a short notice but you can call me Lance.“
Keith doesn‘t get the chance to respond when he is suddenly hauled through the water at a speed that could rival a motorboat.
His heart is racing and he is filled with ecstasy. He doesn‘t remember a time in his life in which he ever felt so free. If these are his last moments, he is lucky to die in such a way. No pain that will potentially follow could make him change his mind. This was worth it.
To Keith‘s mild disappointment, they slow down and eventually come to a halt. It takes a few moments for Keith‘s vision to focus but he soon realizes that they‘re no longer outside. They‘re still in the water but surrounded by rocky walls and to their left, the water is shallow enough for Keith to be able to stand or maybe even sit with his head above the surface.
Instead of speaking up, Lance uses his hand to gently push on the underside of Keith‘s jaw, making him look up and gasp when he sees the beautiful picture painted above him:
The cave opens up to a view of the night sky, the crescent moon providing most of the light that makes this cave visible.
“What is this place?“ Keith breathes, deeply filled with wonder.
“It‘s my secret spot. No one else knows of it. I’ve always dreamed of bringing a human here. And it seems like tonight is my lucky night.“
Keith turns to look at Lance, surprised by the admission.
“You mean I‘m the first human you ever brought here?“
Lance nods.
“But why?“ Keith questions.“Shouldn‘t it be easy for you to get people to come with you?“
Lance huffs and shakes his head. “You know, usually people are afraid of me. You‘re the first human who isn‘t. The only one who ever approached me.“
There‘s a glint in his eyes that Keith can’t identify but before he can think too hard about it, he is suddenly being spun around again and finds himself on his back, pushed against the wall of the cave in the shallow part of the water. To his surprise, the water here only covers his legs.
Lance heaves himself on top of Keith‘s lap and for the first time the young man realizes how heavy Lance actually is.
He may be lean and agile, with soft skin and a tiny waist, yet he is anything but petite. His tail alone must weigh more than Keith‘s entire body. It is also about as long as Keith‘s entire body, he realizes in awe.
He pulls a gasp from Lance when he caresses down from his lower back and over the beginning of his tail. It‘s a bit slimy and each individual scale is very smooth.
“Why aren’t you scared?“ Lance breathes and gasps when Keith uses both hands to grab his behind.
“I‘ve wanted this for a long time. I‘ve been dreaming about this for years.“
Lance moans and practically melts on top of Keith. Keith shuts him up by capturing his lips with his own and he can feel Lance‘s claws digging into his shoulders.
His heart speeds up. This is it. These are his last moments alive. They may last for a few minutes only or several hours, who knows. But he braces himself for pleasure and pain. Welcomes both.
His clothes lay discarded in the water next to them, Lance is half laying on top of him, rutting against Keith‘s hard dick and kissing him messily.
If it didn’t feel so fucking good, Keith would wonder how siren sex works, what genitals male sirens have, if Lance even is male? He certainly appears to be but so far he hasn‘t felt anything but soft flesh in between scales.
Suddenly Lance grabs his hand and guides it down to the front of his tail. After rubbing it up and down, Keith can feel a slit opening. Lance‘s eyes gloss over with arousal.
Lance removes his hand to start feeling Keith up and Keith keeps rubbing Lance. The slit opens more and more and a gooey substance escapes. Experimentally Keith dips his finger inside and it has Lance moaning brokenly and throwing his head back.
He likes his reaction so he adds another finger and starts pumping in and out.
Lance‘s insides are wet and slimy and very very warm but Keith can also feel something wiggling in there which is starting to push against his fingers.
He keeps going until his fingers are quite literally pushed out of Lance’s hole by a slimy but ribbed, long tentacle. Keith gasps, somehow he hadn‘t expected this.
The tentacle keeps coming out of Lance until it reaches the length of Keith‘s forearm. Maybe it shouldn‘t be surprising considering the size of Lance‘s tail but it still makes Keith gulp.
Lance pushes Keith down swiftly and his back hits the ground. Lance heaves himself fully on top of the human. He grabs his legs and spreads them and lines the tentacle up to Keith‘s pussy.
“Wait!“ Keith yells out, mildly panicked. Lance stops but raises a brow.
“Isn’t this what you wanted?“
Keith struggles to find the right words but eventually he settles for: “Yes, it is! But you can‘t just push inside your… um… tentacle? It‘s huge! I need to prepare myself.“
Lance looks confused but nods and Keith wastes no second before starting to touch himself.
He starts by gently rubbing over his vulva, going in circles before he zeroes in onto his hole. He circles it before carefully pushing in the tip of his finger. He winces at how dry it feels despite the salt water on his fingers. Suddenly an idea pops up in his head.
“Um, do you mind?“ he asks, reaching his hand out to Lance’s dick. It is then that he realizes Lance is watching him, completely enthralled.
It takes the siren a second to snap out of it and nod and then Keith wraps a hand around the tentacle.
It reacts instantly by curling around his hand, stroking him - or itself on him?
Keith barely has to move his hand for Lance to wimper and rock into the touch.
He lets go again, hands now thoroughly covered in slick and spreads the gooey substance all over his pussy. He dips his finger inside and it immediately feels better.
He continues using Lance’s slick as a lubricant until he‘s sufficiently prepared.
When gives Lance the okay and the siren finally glides into him, Keith keens at the sensation.
It feels very different from a human dick. The whole ordeal is much wetter and slimier but it‘s not as offputting as it perhaps should be.
At first it feels softer - Lance’s dick is more squishy than a human dick - but he keeps pushing deeper and deeper until it starts really stretching Keith out.
He can feel the tentacle squirming inside him and it drives him crazy. At the same time his hole is being stretched so well and Lance is barely even halfway inside him. He keeps going until Keith has to stop him, taking a minute to adjust.
Meanwhile the tip of Lance’s dick is gliding against his walls, massaging his insides.
It feels unlike anything he‘s ever felt before and he can‘t get enough. It has him already panting hard and quivering from arousal. He can‘t imagine how much more intense it will get from here on out.
When he finally gives Lance the go to push in the rest, he almost screams. The last few inches are so much thicker and harder than the tip of his dick and it makes him feel absolutely speared.
Once Lance is fully inside him, he gives Keith a moment to get used to the feeling before he pulls out slightly and then pushes back inside. He‘s going slowly, trying not to hurt the human.
Meanwhile Keith is losing his mind over the sensation. He feels so full and at the same time he can feel movement deep inside him. So, so deep.
When Lance pulls back, it rubs against his walls all the way from his cervix to his entrance and when he pushes back inside he swears the tip of the tentacle is wiggling its‘ way into his cervix. He moans brokenly, digging his fingers into Lance‘s arms.
Lance smirks at the display and picks up the pace. He starts fucking into Keith faster and harder and now his cervix is penetrated by the small tip of Lance‘s dick with every thrust. It has Keith gasping and whining, spit dribbling from of the corner of his mouth.
Keith is so turned on, he feels ready to burst any second now.
Lance keeps going, keeps fucking him and finally the dam breaks.
Keith‘s orgasm washes over him like a tidal wave. He digs his nails into Lance‘s biceps and chokes up. It‘s so intense he can‘t even make a noise.
Lance seems to feel the contractions and whimpers, speeding up his thrusts.
After what feels like an eternity, Keith gains his voice back and immediately starts moaning. He‘s still coming and he squeezes out every last bit of pleasure that he can get.
When he eventually comes down from the high, Lance is still frantically chasing his own and Keith can feel himself getting sore. But he doesn‘t want to stop it, doesn‘t want to rip Lance‘s pleasure from him when he‘s so close. So he endures it, lets the discomfort bleed into his cacophony of sensations.
By the time Lance cums, Keith is so riled up again, he hooks his legs around Lance and traps him inside. He‘s moaning and whining as Lance bucks into him and then Keith can feel his insides filling up with Lance‘s cum. It‘s so much that it starts flowing out of him, even squeezing past Lance‘s huge cock.
It‘s too much and Keith cries out, humps the tentacle until he cums again. His pussy squeezes every last drop out of Lance and when the siren collapses on top of him Keith is about ready to pass out. Before he succumbs to the blissful void of sleep, he can feel Lance‘s lips on his and he lazily reciprocates until everything fades to black.
Keith wakes up to a sleeping siren on top of him.
He groggily looks around, trying to jog his memory until he remembers exactly what happened last night.
He feels relaxed and well rested and warm under Lance‘s torso and his massive tail. And yet something is off. Shouldn’t he be dead by now?
Keith tries to get up without waking Lance but as soon as he wiggles out from under him, the siren stirs and blinks slowly. When his eyes fall on Keith, a lazy snails spreads over his face. He closes his eyes again as he yawns and stretches his body out, still laying half on top of the human.
“You’re a great pillow“, he slurs before nuzzling his head into Keith‘s stomach.
The gesture does something to the young man that he didn‘t expect.
It takes approximately ten seconds for Lance to fall back into a deep slumber and the sight has his heart doing a little flip.
Keith waits a while longer before attempting another escape and this time Lance stays asleep.
He gets up and puts his clothes back on. After spending a night half covered by salt water, his skin is all pruny and a little sore.
He didn’t consider this being an issue, as he expected to be inside a siren‘s stomach by morning. Maybe Lance just likes to take more time playing with his food. Should he stay and find out?
But then he thinks of last night and how much joy he felt.
For the first time in his life, since he was a little child, he felt genuine happiness. And it stings.
He hadn‘t realized he was capable of those emotions.
And now that he‘s had a taste of it… is he really ready to leave it behind? Can he really let his life end, knowing what life can have in stall?
He looks back at Lance who is curled up in a ball now that he isn‘t resting on Keith anymore. He looks so peaceful.
Keith could just stay and wait to become Lance‘s meal eventually. He would spend another few hours, days, potentially even weeks feeling joy and then it would be over.
Or… he could leave and start over. Go home and look for things that make him feel anything remotely like Lance did.
Both options make his heart ache but eventually he decides to leave.
He may never see Lance again but he knows now he is capable of feeling joy and he wants to give life another shot. If it ends up not working, he can always come back to this beach. Lance surely isn‘t the only siren looking out for prey around here…
He almost makes it out of the cave until he hears a splash and then Lance appears next to him.
“Where are you going?“ he demands, eyes squinted. “You‘re gonna fuck me and then just leave without so much as a goodbye? You‘re gonna smash and dash? Not what I expected of you, Keith. I have to say I‘m a little disappointed.“
Keith sighs defeatedly.
He eyes the land exit and he wonders if he can outrun Lance but decides against trying and plops down, resigning to his fate.
“I came here to die. Honestly I expected you to kill me last night, after or while fucking me. I wanted one last good experience before going out. But I changed my mind this morning. I guess I am weak for not going through with my plan but… I want to live after all.“ He snorts before adding: “Sleeping with my killer has made me realized I don‘t want to be killed.“
Lance listens without interrupting but he stares up at Keith, wide-eyed, looking almost hurt.
“I wasn‘t going to kill you“, he breathes. “All I wanted to do was fuck you from the moment I saw you. That‘s all.“
Keith blinks.
“But“, he starts, confused. “Isn‘t that what sirens do? They seduce humans so they can kill them when they are the most vulnerable?“
Suddenly Lance looks furious and Keith flinches when he bursts out: “What kind of monster do you think I am?? I am sure this has happened before but we aren‘t all the same! Just because some humans go out to sea to hunt us, I‘m not going to assume every human I come across wants to steal my scales! I‘ve never hurt a human in my life. I never even touched a human! You‘re the first… you‘re my first… everything…ever…“
By the end he trails off and lowers his gaze. He brings his hand up to his face and starts biting on a claw.
In this moment he couldn’t look any less than a predator. He looks small, bashful, nervous.
Keith realizes a weight has been lifted off his shoulders and he relaxes, chuckling. Suddenly everything feels so simple.
“What are you laughing at?“ Lance hisses, shoulders drawn up and looking ready to bolt.
“I‘m sorry“, Keith sighs but the smile stays on his lips. “I‘m just really relieved. I thought I had to make a really difficult choice.
I mean, I already made it. I wanted to be alive over staying with you. Despite my night with you being the one thing that has made me happy in, like, fifteen years.
But it seems I don‘t have to make that choice anymore.
I‘m sorry for assuming you‘d kill me. All I ever heard about sirens came from stories and legends passed down from other humans.“
He can see Lance relaxing and his big, blue eyes are trained on Keith once again.
“Are you saying you want to see me again?“ the siren says, it’s almost a whisper.
Keith nods. “If you‘ll have me.“
A tentative smile stretches over Lance‘s face and after a few seconds Keith is being pulled head first into the water.
His scream is cut off but then he can breathe again and finds himself in squeezed to Lance‘s body. He mockingly shoves his siren but when he starts backing off, Keith holds onto him and keeps them in the embrace.
They stay like this for a few minutes, breathing in each other‘s scents and reveling in their shared warmth.
Eventually Keith has to leave. He needs to wash the salt water off himself and give his skin some rest. He also needs to call his job and figure out if he‘s fired or not and potentially find a new job.
But all of that sounds fine. It‘s sounds manageable because at the end of the day he has something to look forward to, someone to return to. Something he fears losing.
He can‘t wait to meet Lance a second time and get to know him better, ask him all sorts of things about sirens and life in the ocean.
And most importantly: the joy that it brings him to be with Lance.
So, he goes home but not without promising to come back tomorrow.
