The sea presses heavy on all sides, black and endless. Only the beams of their helmet lights cut through the dark, slicing over rusted iron and broken planks of the ancient wreck sprawled across the seabed. Goku’s heart pounds with the thrill of it – treasure hunting’s always a gamble, but this? This is a big one.
They’ve researched it for years – a magical sphere capable of granting wishes. It sounds fake – too good to be true – but it exists, and according to the radar in Goku’s hand, they’re right in front of it.
“Keep up, slowpoke,” Goku’s voice crackles through the comms, teasing as ever. He looks over his shoulder at Vegeta so the light flashes into his eyes, a smug grin forming on Goku’s face as he catches Vegeta wincing. “You’re draggin’ your fins.”
Vegeta’s sharp reply comes immediately. “You’re the one darting around like a Goddamn guppy. Stay focused.”
Goku grins to himself behind the helmet, not slowing at all. He loves needling Vegeta, especially down here, where they have nowhere to run from each other. “Focused, huh? You sound nervous, Vegeta. Afraid of a little dark water?”
“Tch. Of course not! Insufferable clown.”
Goku laughs, bubbles streaming from his regulator as he swims deeper into the wreck. The hull yawns open like a gaping jaw, a grave of iron and coral. He pushes inside, light glancing off barnacle-crusted beams and shattered glass from some long-forgotten ornament.
Then he sees it.
At the far end of the old ship, half-buried in sand and silt, gleams a chest. The kind he’s only ever seen in old picture books – rusted gold corners, wood eaten by the sea, but still intact.
“Jackpot,” Goku whispers. His fingers flex inside his gloves, excitement buzzing hot through his veins. “Vegeta, you seein’ this?”
Vegeta swims up beside him, silent for a beat, visor glowing in Goku’s light. “…It does look promising.”
Promising? Goku wants to laugh. Vegeta never wants to admit when Goku’s right.
Goku kicks toward it eagerly, brushing silt off the lid. His fingers dig into the edges, testing the lock. “Help me get it open.”
“Don’t be so impatient, Kakarot.” Vegeta hovers close, muttering curses as he grabs the opposite side. “We don’t even know if it’s safe. There could be –”
The water around them shifts. It’s colder, heavier. The hairs on Goku’s neck stand as something moves in the dark behind them. Something vast.
He freezes and slowly turns.
Out of the shadows, a gigantic shape uncoils – then another. Long, sinuous limbs slide over the wreck’s beams with impossible strength, snapping and crumbling the structure.
Tentacles. Massive. Too many to count.
“Oh… shit,” Goku breathes, pupils dilating as the first one stretches toward them.
The water ripples as the tentacle shoots forward.
“Vegeta –!” Goku starts, but it’s too late. The tentacle whips malevolently right at him, curling tight around his waist. He grunts as the pressure clamps down, dragging him roughly away from the chest.
Vegeta’s snarl cuts through the comms. “Let him go!” He lunges, knife flashing in the beam of his helmet light, slashing at the tentacle. Dark blood plumes into the water, but the tentacle only wraps around Goku tighter.
“Gah!”
It’s getting harder and harder to breathe. The thing squeezes around him like it’s testing his shape, its strength obscene. He thrashes, fingers ineffectively tearing at the tentacle, but more limbs are uncoiling in the dark. One wraps up his leg until the tip of it rubs his cock through his wetsuit. He tries to fight back, but it’s too late. Another one curls around his chest, suctioning itself to Goku’s nipples.
“Oh, you’ve gotta be kiddin’ me –” Goku’s voice cracks in the comms, panic laced with furious disbelief. “This – this thing! It’s feelin’ me up! Hurry and get me outta this, Vegeta!”
“All I have is this puny fucking knife! I’m cutting as fast as I can!”
“Not fast enough! Go faster!”
But yet another tentacle snakes out, faster than lightning, and coils around Vegeta’s arm, wrenching the blade away. “Fuck!” He swears savagely, struggling as the tentacle drags him closer to Goku. “What the fuck?!”
They’re both yanked toward the center of the wreck, caught like anchovies in the tightening knot of limbs.
Goku’s chest heaves, pupils blown wide. What the heck is happenin’?! His body’s reacting to the firm, invasive pressure stroking all over his suit like it wants… more?
“Hey – cut it out, you… you overgrown squid!” He gasps, but his words die as another tentacle slides over his ass, lingering on each cheek before squeezing and squeezing, massaging him until it feels too good to resist. “Ah!”
The chest is forgotten. The real treasure, it seems, is them.
Tentacles writhe through the water like living chains, binding them closer and closer. Goku’s chest collides with Vegeta’s, helmets clacking before they manage to steady themselves, tangled in a mess of limbs and rubber and slick, sinuous muscles they can’t break free from.
“Fuck – Vegeta!” Goku snarls, hands scraping uselessly at the slippery flesh holding him. “Do somethin’!”
“What the hell do you think I’m trying to do?!” Vegeta’s strained voice crackles through the comms. He wrenches his arm free for a second before the same tentacle snakes right back, seizing his wrist and forcing it down – against Goku’s crotch.
Goku jerks. “H–hey – watch it!”
“Like I’m doing this on purpose?!” Vegeta snaps, but his face – Goku can see him through the curved glass of his helmet – is flushed, his lips parted, every breath fogging against the visor.
The tentacles wrap around them both and begin to move them, really move them – rolling their bodies together with ease, pressing chest to chest, thigh to thigh, cock to cock – like a child making two dolls kiss. The water ripples with every grind, every forced slide of their wetsuits, until Goku can feel Vegeta’s body heat through the neoprene. He bites down hard on a noise trying to slither its way up his throat, jaw locked tight. He can tell Vegeta’s doing the same, shoulders rigid, mouth trembling with sounds he refuses to let out.
Then one of the limbs slithers higher along Goku’s leg, tightening around his thigh before curling up and nudging his asshole. His yelp distorts the comms, part rage, part something he’s not sure he should be okay with feeling. “D–damn perverted calamari!”
The creature pulses around them, as though it’s pleased. Goku sees another tentacle clamp onto Vegeta’s ass, suction cups popping against it. Vegeta hisses sharply, body jerking, and then his gaze snaps up. Through the murk and their helmets, their eyes lock.
“Don’t – don’t look at me like that,” Vegeta grits out, even though he’s the one staring.
Goku’s teeth are bared, eyes burning. “Like what?” he spits, twisting in the tentacle’s grip, his cock hardening against the confining suit despite every ounce of anger in him. “Like you’re the one enjoyin’ this?”
“Shut up!” Vegeta snarls – but the retort fractures into a moan when the tentacles shove them tighter together, grinding their hips, cocks rubbing so hard they’re almost chafing. Meanwhile, other limbs slither around them – flicking at their nipples, squeezing their inner thighs, tracing every weak point like it knows where to press.
It isn’t binding them like prey it means to kill – it’s playing with them.
All of a sudden, the beast drags them deeper into the hollowed heart of the wreck, away from the treasure they came for. The sea’s pressure builds, water colder and darker. Still the tentacles grind them together, as if the thing knows exactly what it’s doing.
“Fuckin’ let me go!” Goku thrashes, kicking, but his legs are wrenched apart by the powerful limbs. Another coils up his back, looping around his arms and forcing them behind him until his chest strains forward. “I swear, when I get outta this –”
“You’ll what? Bite it to death?!” Vegeta snaps back – but the tentacles spread him wide too, twisting his body in the same helpless arc. His fists clench and unclench uselessly. “Ugh – damn it!”
Goku laughs, delirious, feral. “What’s wrong, Vegeta? Don’t like bein’ touched?”
“N–not like this,” Vegeta growls – but the words disintegrate into a guttural noise as the tentacle pushes hard enough to pierce through his wetsuit. And Goku sees it happen – the tip slides between Vegeta’s ass cheeks and Vegeta squawks. “The fuck is this thing do–?!”
His whole body jolts against Goku’s when the tentacle shoves right into his asshole.
Goku’s eyes widen in pure disbelief.
“Oh, shit! No way, Vegeta, it’s fuckin’ you!” He can’t help but throw his head back with a surprised bark of laughter – cut short when a tentacle worms through his own wetsuit, breaking past the thin barrier of neoprene. It presses against his rim, suctioning and teasing his hole, breaking his laughter into a moan. “Ohh–hh – fuck –”
“Serves you right, Kakarot,” Vegeta spits, but he’s panting, teeth bared as the tentacle thrusts in and out of him. His face twists like he hates it, but his cock is hard as fuck, straining painfully against Goku’s as the creature keeps grinding them together in perfect sync with each pistoning stroke. “Getting – ngh – exactly what you deserve.”
“And you’re not?” Goku fires back, gasping as the tentacle finally snakes past his rim, spearing him open, stretching him so deep it sears. It hammers into him fast, and Goku can feel the small suction cups sticking to his insides. “Mmm – fuck!”
Vegeta snarls, but he can’t stop the reflexive jerks of his hips, cock sliding hard against Goku’s as the beast fucks them both without mercy. More tentacles thread between them, prying at the seams of their wetsuits until the fabric tears with a sharp stretch. Their cocks spring free into the cold water, twitching violently under the creature’s grip as it wraps around their lengths and strokes them.
“Goddamn it,” Vegeta hisses, composure crumbling as the tentacle drives deeper, filling him until his spine arches back and forth. “Goddamn thing – ahh – knows exactly where to – fuck –”
“Quit whinin’! We gotta find a way to get outta this!” Goku’s trying his best to stay focused, but the tentacle inside him is stretching him in a way no cock ever could. The sound he makes is a filthy, desperate moan. “Ohhh… f–fuck…”
“Nnh – wait! It’s stroking and fucking us like it wants us to come.” Vegeta groans raggedly, head falling back as he thrashes uselessly one more time. “If – if we come, it might – hnf – leave us alone.”
“Ya sure you’re not – mmh – just sayin’ that ‘cause you’re gonna come?” Goku challenges, even though he feels the same. “You like it, Vegeta – you’re droolin’ like crazy in there!”
“Shut the fuck up!” Vegeta bares his teeth, but his groans are spilling dirty into the comms, mixing with Goku’s.
The tentacles pound harder, plunging into both of them at an unforgiving pace, grinding their bare cocks together until every thrust sparks white-hot. Their snarls collapse entirely into moans now, curses bleeding into pleas. The water churns with their struggle, until it’s impossible to tell where Goku ends and Vegeta begins – both of them writhing, clawing, losing themselves in the monster’s grasp.
“Fuck, fuck, fuck! Vegeta – I can’t –” Goku’s voice breaks into a whimper when the tentacle angles just right, the thin tip flicking and tickling his sweet spot over and over. Every brush sends sparks straight through him.
“S–stop resisting,” Vegeta groans, hips snapping helplessly against Goku’s. His whole body is shaking, wrung out between brutal thrusts and suffocating pressure. “Just – just listen to me and come already!”
For some reason, that does it.
“Ghh – ahh – Vegeta!” Goku shouts, the sound echoing through the dark water, his cock shooting hot streams of cum into the abyss between them.
Vegeta follows a heartbeat later, biting down on his lip so hard it splits, choking on his own groan as he comes hard, cock pulsing against Goku’s. The beast continues to milk them, slowing its thrusts but tightening its grip around their cocks, forcing them to ride the waves of pleasure until they’re both left limp and shuddering, cum mingling and drifting into the black sea.
There’s one final squeeze, like the beast is savoring the last drop, before it yanks its tentacles free from their holes, loosening its grip and releasing them back into the wreck’s eerie silence. They’re left floating in the water, wetsuits shredded and mangled, water chilling their skin as their adrenaline slowly drains away.
Goku shivers and he lets out a weak, incredulous laugh. “J–Jeez… what the… hell was that?” The heat of it fades, leaving the cold, dark water pressing against them. “Next time… we’re bringing grenades.”
“Next time,” Vegeta growls, teeth clenched, shivering. “I’m doing the navigating.”
