Chapter Text
Jungkook barely made it when he escaped from the castle, jumped over the tall stone walls, ran without abandon until he felt somewhat safe, away from the unbearable hassle of his daily life there.
He almost slips on a rock, not really caring about where his feet have taken him. His labored breathing doesn't calm down as his eyes search for shelter to spend the night, at least until he gathers the crumbs of himself to get back to that hell.
As his eyes wander, he realises that he's at the royal docks. He sees the ships that belong to his family and turns away without a second look, running further into the shore, to the places no one ever goes to, away from the remembrance of his life.
He runs and runs on the wet sand until he can't, his feet hurting from the sharp particles digging into them. He sees rocks sticking out from the sea like dark statues, full moon shining silver on the roaring waves, crashing and exploding into mesmerising, glittering fans of foams.
There's a big, dark hole right where the rocks are condensed, somewhere he can climb and check out.
So Jungkook does just that, slowly moving so that he doesn't slip and die somewhere he will never be found. If he dies he's going to make it count.
The inside of the hole is a cave, and as Jungkook's eyes get adjusted to the darkness, he starts noticing that the cave is actually sparkling, lighting up softly with blue-green luminescence from the rocks that emit the moonlight from outside.
Under the slight lighting he can pick out the shape of the place. He has to walk while holding the wall with one hand, for a calm stream of sea branches deep inside the cave.
He stares in innocent amazement as he walks, mouth open as he appreciates the beauty of nature around him. The lights are distant and soft, not enough to see clearly, but they're still gorgeous.
His wet feet softly patter on the rock floor, the tulle of his thin white garments flowing around his calves peacefully. His corset is tight around his narrow waist, the thin white fabric stretches around his shoulders when he leans down, finally having found a place flat and safe enough to sit.
Jungkook mindlessly tucks his black locks behind his ears, trying to find peace in the stillness around him. Watching the sea crash through the entrance at a distance, listening to the swoosh of the waves resonating in the cave. He looks down at the stream, right into the void of the blackness underneath his feet.
He has to be crazy to stick his feet into that, and he is. So he does it, a warm sigh escaping his pink lips at the cold water engulfing his worn feet. The white tulle of his dress drifts aimlessly in the water around his knees, so thin that it's almost unseen.
Jungkook stares distantly into the endless abyss, trying to calm the storm in his head. He's glad he's found this place, he will definitely use it for the later escapades when his life just gets too much to bear. He just can't stand it sometimes, when the burden on his shoulders gets too much. He wishes he could just escape forever.
He sits there for god knows how long. After his eyes zone out of focus from not blinking, he notices the rocks inside the water are lighting up. It's so faint that he barely sees it at first. A strange, cold chill runs down his spine, colder than the air around him and he shivers helplessly.
Those lights, slowly, they get a little brighter, a little more brighter, turning into distant, round shapes. They seem to be getting closer, swimming around distantly.
Those are definitely not the lights from the rocks. Those are rings. Glowing, bright, blue rings floating inside the void.
Jungkook, he should draw his feet out of the water. He should… run. But there's a problem, his body won't move. No matter how much he wants to alert his body and get up, every single survival instinct kicking into drive, he just can't.
He sits frozen, mesmerised by the waver of the brightness on the blue rings as they get bigger and bigger, accompanied by a slight dark gray hue that connects them, stretching almost entirely through the width of the stream.
All blood rushes to Jungkook's ears, his heart explodes against his ribcage when he realises.
This is an enormous, alive monster that's emerging from the black water.
Jungkook holds his breath, all air knocked out of his lungs as he can only watch the black creature surge through the darkness. He can't hear anything, not even the waves in the background as something thick, cold and foreign creeps around his calf under the water. It's deathly still for a second, the wind howling in the cave as the blackness rises.
The shadow slowly finds form in front him, getting taller, shifting and changing until…
Until Jungkook recognises the silhouette of a… man standing in front of him.
Over the water.
Jungkook can just stare. He couldn't ever move from this spot. He's sure this is his last night alive in this world because he thought deadly sea monsters only existed in children's tales.
His eyes begin to water, vision getting blurry, feeling so utterly helpless against this thing in front of him.
"P-P-Please." a small sob escapes his mouth.
An agonising, sharp pain strikes his chest when the monster opens its eyes.
Bright blue rings are staring into him, burning into his soul. They are horrifyingly bizzare and foreign.
"D-don't.. kill m-me." Jungkook stutters, a hiccup shaking his frail, scared body, followed by more. Jungkook's frame wracks with sobs uncontrollably, hands shaking in a death grip over the edge of the rocks.
The blue rings floating both in and out of the water seem to glow brighter for a second, before the monster, man, lurches over the water to approach Jungkook. Jungkook almost screams, but his lungs contract painfully instead.
The only thought in Jungkook's head is "cold" for a moment, when he feels the man's… arms wrap around him in a snug hold.
Another cold shiver shoots down his entire body at the contact, sagging like a ragdoll, paralysed from utter, pure fear.
The cold thing creeps further up his calf and the man hoists him up like he weighs nothing. Jungkook feels the shift in weight when the man presumably steps onto the solid rock, taking a few steps to lay Jungkook down on it, probably to eat him.
Jungkook lies on the cold surface like helpless prey, his black hair messily haloing around his flushed head. Hot and cold flashes surge through his body, the soft blue green lights at the ceiling of the cave a blur.
He trashes around as the cold, wet thing continues to creep up his leg, another joining on his other leg. He almost hits his head on a rock before he feels a hand cushion the blow.
Jungkook's eyes shoot open, no longer scrunched. Suddenly he's aware of the brighter lights and the man staring at him over his head, he has a face.
A handsome face. In fact, Jungkook would love to have this man in his bed in any other circumstance. But his luck has it that he's going to be eaten as his prey.
"Are y-you gonna eat m-me?" Jungkook slurs, round doe eyes wide with shock.
The man cocks his head to the side as he watches Jungkook like he's the one that's a strange sea creature and not him. His blue eyes are burning softer now, less of that bizzare foreign light in them.
He shakes his head slowly, as if to signal no. Jungkook is more shocked that he seems to be communicating with him rather than digging his fangs into him instantly.
"N-no? Are you sa-saying you won't…" He gulps. "Eat me?"
"Not eat."
The man speaks and Jungkook's breath hitches. His voice is deep and unmistakably wild, something definitely inhuman in it. Like rocks are talking behind a human's voice.
Jungkook notices the black ink swirling down the man's dark but ashen toned skin, mixed with the glowing water dripping down his bare, wide chest. The lights wash his wide stature broad and strong, and Jungkook sees that he's completely naked.
His eyes immediately get transfixed between his legs. Through a vertical slit, a huge, thick and gritted cock curves up to his belly, redder, bigger and thicker than any he's seen on a human, ever. It seems almost painfully swollen, glistening and dripping at the tip.
Before he can think about why this monster is hard, Jungkook sees the blue rings flailing around the floor. They're black tentacles, connected to the man's back. And two of them are currently parting his thighs apart and two more are winding around his wrists.
"Y-you can talk?" Jungkook asks dumbly from where he's lying on the ground, his eyes flitting over the man's cock and his face.
The man grunts as he hastily grabs and rips Jungkook's tulle skirt to shreds. Jungkook hiccups with fear, body instinctively trying to close up on itself but the tentacles' hold won't let him.
There are rough hands trying to tug his corset off him and Jungkook can't help the maniacal laugh that bubbles up at the thought.
"D'you want me to take it off?" Jungkook asks between the trembling of his lips, replacing the man's hold on his corset. The man nods and Jungkook complies, prying his corset off and removing what's left of his dress over his shoulders.
The man gives a pleased grunt as he buries his nose in Jungkook's neck. Jungkook hiccups again, and lets out the laugh he's been holding in.
His arms wiggle to check the constraint of the tentacles, and he realises he can move them freely as he instinctively wraps his arms around the man's thick neck. The man is rubbing his face to the side of his neck and another tentacle slowly wraps around Jungkook's soft cock. He gasps in surprise, it's so wet and soft, licking around his length in an undulating motion.
The monster slots himself between Jungkook's legs and Jungkook is shocked by the familiarity of the situation. His gritted cock rubs against the soft meat of his thighs, it feels like it's covered with something viscous, slippery against his skin as it continues to secrete the fluids.
"What are you gonna do to me?" Jungkook asks, voice shaken, before he gasps and arches over the surface as another slippery tentacle reaches between his legs and moves inside his hole.
"Mate. Breed you" The man grunts deeply as he licks over Jungkook's neck, his tongue unnaturally slippery and cold against his skin.
"Ah-" Jungkook moans as the tentacle wiggles its way inside his hole and slowly fills him. It's an extremely strange sensation, totally different from a cock because it's much softer and wetter, yet thicker, just stuffing him and preparing him for something much bigger.
As it continues to plug his hole up with the wet muscle, a sucker rubs directly on Jungkook's prostate and Jungkook cries out, already sensitive and overwhelmed from everything. He can't even bring himself to question how absolutely weird the situation he's in, that the monster said he's going to breed him, but he guesses it's better than being eaten alive.
"D-D'you have a name?" Jungkook chokes on a gasp as the tentacles hold him tighter and the one inside him rubs against his prostate, slowly. He squirms from the blinding pleasure, it's too much and he's delirious, but he wants more.
"Namjoon" The man breathes against the side of his face where he's mouthing at. His cock steadily gushes out more fluids, soaking Jungkook's hardening cock with it. Hard but dwarfed under it.
'Namjoon' sounds so normal for a second that Jungkook drifts out of place mentally until Namjoon's tentacles push his ankles over his head, bending him in ways he wasn't ready for.
"Breed - now" Namjoon rasps in his rough, deep voice, hands squeezing at Jungkook’s soft body, at the expanse of his creamy skin whenever it gives. He leans back to properly handle Jungkook into the breeding position.
Jungkook panics for a moment. He holds out his hands at Namjoon's hard chest, which the monster responds with a confused frown.
"J-just wait a second. It won't fit." Jungkook tries to warn, just as Namjoon wiggles the tentacle deeper inside him.
"Fuck!" Jungkook whines pitifully, squirming against the tentacles as Namjoon slowly wraps another one around his throat. The one rubbing his cock finally lets go and Jungkook feels like he can breathe again.
Namjoon's giant cock pulsates against his thigh and he pushes the tentacle inside deeper as if to say You were saying? before pulling it out. Jungkook feels tears brimming in his eyes again when the suckers rub on his prostate through the entire length.
He feels terribly empty.
He wiggles as he feels the tentacle around his throat wrench lightly. He moans brokenly. "P-please"
His hole feels totally at peace with the huge intrusion when Namjoon finally lowers himself over Jungkook's body and the tip of his cock breaches his entrance. Jungkook chokes on a cry and arches his back, holding onto Namjoon tighter and letting the monster engulf him in his embrace, almost double his size.
Namjoon must have released some sort of muscle relaxing chemicals because his wet cock slips right in, throbbing and pulsating inside Jungkook's walls, leaking more fluids.
"Fuckkk!" Jungkook cries out as Namjoon begins to move, the grits on his hard cock dragging right against his walls making him lose his mind. Namjoon reaches in so deep that Jungkook can feel him rearranging his guts to make room.
He looks down at his belly when Namjoon rolls his hips, caged in by his arms. There's a protruding bulge in his stomach, rolling at the same time as Namjoon's hips and Jungkook throws his head back, warmth shooting in waves between his legs throughout his entire body.
Jungkook shudders as he holds onto Namjoon, trying to have some leverage but is held down by the tentacles' grip on him. He digs his nails into Namjoon's back and screams heartily when Namjoon pulls back roughly to ram right back in, a deep growl at the back of the monster's throat, cock producing a slushy sound from the wetness.
His cock is so big, so thick that Jungkook has never felt this full before. He's never had something this enormous inside him, and he's sure that he's never going to be satisfied by anyone else in the future.
"Ah, ah please!" Jungkook whines, voice already strained and ruined with overwhelming pleasure. He feels the pressure rapidly building inside his guts, eyes going hazy and unfocused when Namjoon holds him tighter and starts drilling his cock inside him, the sound so wet and obscene echoing inside the cave.
Namjoon smells like salt over him, and he's so heavy but Jungkook is revelling in the pressure. He's never felt so good before. Instead of blood, there's pure hot ecstasy soaring inside his veins, spreading to his whole body.
The tentacle around his neck squeezes tighter and Jungkook feels even more lightheaded, he lets loose and focuses on the pleasure. The steady thrusting of Namjoon's wet cock against his walls, its enormous girth splitting him apart and the grits rubbing over his sweet spot repeatedly.
Jungkook breaks into a full body shudder, body coiling like a taut wire, toes curling and his eyes rolling back, pink lips falling in a perfect O as pleasure erupts deep inside him and he's coming. His vision flashes white, his cock spurting between their moving bodies but there's no stopping Namjoon.
He thrusts faster, holding Jungkook down and practically hammering his cock inside until his hips ram to a stop. He digs his sharp teeth into Jungkook’s soft neck and his body goes still.
Jungkook's eyes shoot open when he feels it. A bulge in Namjoon's cock pushing inside him, moving through his cock. It's the size of a fist, and Jungkook cries out from oversensitivity. The pressure on his prostate as the knot rolls over it is immense and almost unbearable, his hole stretched to its limit.
The knot moves deeper until it pops inside Jungkook's guts, followed by a few more and Jungkook can only hiccup from the pressure, reduced to a babbling mess of oversensitive nerve endings. The eggs settle heavy and hard inside him.
Namjoon breathes heavily over him, his cock throbbing between dumping the eggs inside Jungkook's ass. After the last egg pops out, his cock gushes out warm come in thick pulses, bloating Jungkook out even more, and Namjoon finally pulls out.
Jungkook's stomach lurches, so overwhelmed that he hiccups and comes again with a broken whimper, his puffy hole gaping around nothing and gushing out slick with wet squelches. He's drooling and crying as he feels Namjoon's hands on his wet cheeks.
Namjoon is staring at him as if he's the most beautiful thing he's ever seen, despite how utterly disgusting Jungkook must look right now, flushed, bloated and crying.
"Mine." Namjoon emits a deep grumble in his chest, smiling at Jungkook with a wide, beautiful, bloody smile and handsome dimples.
Jungkook can only agree. "Yours." he croaks, voice hoarse and small.
Namjoon presses his forehead to his. "Next - moon. Mine."
Jungkook mindlessly hums, breaking into a fucked out smile. If this is what's waiting for him in his future, then he realises he wants to surrender to it.
