Chapter 28: Claimed in the Deep
The silence after their vow felt both solid and fragile. The eggs pulsed between them, a quiet, urgent clock. Taichi’s gaze held Yamato’s, the amber depths churning with something desperate. Then, without warning, he moved.
His powerful tail whipped, and he was across the grotto in a fluid surge. He seized Yamato’s wrist, his grip unyielding.
“Come.”
It wasn’t an invitation. It was a current, and Yamato was caught in it. Taichi pulled him away from the nest, through a narrow fissure in the grotto wall Yamato had never noticed. The passage was tight, scraping Yamato’s shoulders, the water within noticeably warmer. The bioluminescence faded, replaced by an eerie, dancing blue light from colonies of jellyfish anchored in the crevice roof.
The space opened into a slender vertical crevasse, the walls close and rough with black coral. The water here was thick, almost syrupy with warmth from some unseen geothermal vent below. It hummed, a low subsonic thrum that vibrated in Yamato’s teeth.
Taichi didn’t pause. He spun Yamato and shoved him back against the rough wall, pinning him there with the full, unyielding strength of his body. The merman’s breath was hot against Yamato’s neck.
“You think one time is enough?” Taichi growled, his voice raw, stripped of its usual melodic rasp. His amber eyes blazed in the ghostly blue light. “You come back smelling of that place, of him, and whisper pretty songs, and think that settles me?”
Yamato’s heart hammered against his ribs. This wasn’t the tender guardian of the eggs. This was the feral prince, scarred and possessive. “Taichi—”
“No.” A webbed hand clamped over his mouth, not gently. Taichi pressed closer, the slick, hot length of his tail sliding between Yamato’s legs. “I saw the way you counted those human coins. I see the worry in your bones. You are planning, thinking. I do not want your thoughts.” He leaned in, his lips a breath from Yamato’s ear. “I need you to fuck me until I can’t think. Until my belly aches and swells with your seed. I need to feel you, only you. Not the land. Not him. You.”
The words, filthy and direct, sent a jolt of pure heat straight to Yamato’s cock. The healing saliva’s lingering effect ignited into a conflagration. He was hard in an instant, straining against his rough trousers.
Taichi felt it. A sharp, triumphant grin cut across his face. His tail coiled around Yamato’s waist, pulling their hips flush. With his other hand, he yanked at the fastenings of Yamato’s pants, the fabric tearing in his urgency. The cool water hit Yamato’s exposed flesh, followed by the searing heat of Taichi’s scales.
“Yes,” Taichi hissed, his hand sliding down, claws tracing a delicate, threatening line down Yamato’s stomach. He found Yamato’s cock, already leaking, and gripped him hard. “This. This is what I need.”
He positioned himself, arching his body. Yamato looked down. Between the base of Taichi’s tail and the start of his ventral scales was a slick, pulsing slit, glistening in the blue light. Taichi guided Yamato’s cock to it, the head nudging against a heat that was incredible.
“Now,” Taichi commanded, his voice cracking.
Yamato thrust. There was no hesitation, no gentle entry. He drove forward, burying himself to the hilt in one brutal, claiming stroke. The tight, clutching heat around him was unbelievable, a velvet vise. Taichi threw his head back, a guttural moan torn from his throat, bubbles exploding from his gills.
“Fuck,” Yamato grunted, the sound ripped from him.
Taichi’s claws dug into the meat of Yamato’s back, raking down. The sharp pain was a bright counterpoint to the blinding pleasure. “Harder,” Taichi demanded, his body already moving, riding Yamato’s length with a frantic, rolling rhythm. “Do not be gentle. Claim me again, land-walker. Make me yours. Make me forget everything but your cock.”
Yamato lost himself. He braced against the coral wall, the rough edges biting into his palms, and fucked into Taichi with a savage, driving force. Each plunge was deep, punishing, aimed to obliterate. The wet, rhythmic slap of their bodies meeting echoed off the narrow stone walls, a lewd counterbeat to the hum of the water.
Taichi was loud, unashamed. He chanted filthy, broken phrases in his own tongue, then in mangled human words. “Deeper—yes, there, there—you fill me so good—breed me, Yamato, fuck, breed me—”
Yamato’s world narrowed to heat, pressure, and the wild, beautiful creature impaled on him. He pistoned his hips, his own grunts joining Taichi’s cries. He could feel Taichi’s inner walls fluttering, clenching, trying to milk him dry. “You feel that?” Yamato gasped, driving in again, feeling his balls tighten. “You feel how fucking deep I am? I’m going to fill you up. I’m going to pump my cum so deep inside you, you’ll be dripping with it for days.”
The vulgar promise sent Taichi spiraling. His tail constricted, squeezing Yamato’s waist almost painfully. His slit gripped Yamato’s cock like a fist. “Yes! Now! Give it to me!”
Taichi’s orgasm hit him like a seizure. His whole body arched, stiffened. A raw, ragged scream was muffled by the water as his own release pulsed hot around Yamato’s shaft. The intense rhythmic clenching pushed Yamato over the edge.
He buried his face in Taichi’s neck, teeth scraping skin, and drove home one last, brutal thrust. He came with a shattered groan, his hips stuttering as he emptied himself deep into the clutching heat. Pulse after pulse of hot seed spilled into Taichi, the feeling profoundly primal, a claiming that went beyond skin.
For long moments, they hung suspended in the blue gloom, panting, connected. The violent energy bled away, leaving them trembling against each other. Yamato’s arms shook where he braced them. Taichi’s tail slowly uncoiled, its grip becoming an embrace rather than a bind.
Yamato softened, slipped out. A pearlescent strand of their combined release drifted into the water between them. Taichi watched it, his expression dazed, satiated. He reached out and captured it on a claw, bringing it to his mouth, his tongue cleaning it off with a slow, deliberate swipe. His eyes never left Yamato’s.
“Mine,” Taichi whispered, the feral edge gone, replaced by a bone-deep certainty.
Yamato nodded, breathless. “Yours.”
They drifted downward, settling on a ledge of smoother stone. Taichi curled against him, his head on Yamato’s chest. Around them, the anemones embedded in the walls pulsed with a soft, renewed light, as if feeding on the energy they’d spent.
“The coins,” Taichi said quietly after a time, his voice back to its normal rasp.
Yamato tensed. “What about them?”
“They are a tool. A land-tool.” Taichi’s claw traced idle patterns on Yamato’s sternum. “We need a sea-tool.”
“A boat,” Yamato said, the reality of it settling heavy in his gut. “A real one. Not a rowboat. Something that can go far. Where the nets aren’t.”
“Yes.” Taichi looked up, his gaze clear now, focused. “The hesitant one… she strengthened with our song. But a song is not a current. It will not carry them to safety.” He took Yamato’s hand, placed it over his own lower belly, which was warm and slightly full. “This… this is a promise. But a promise is not a plan.”
The warmth of his own spend inside Taichi was a tangible mark, a biological vow. It shifted something in Yamato’s mind. The coins were no longer just escape. They were a down payment.
“Kaito’s boat,” Yamato said, the words leaving a bitter taste. “The Siren’s Curse. It’s fast. It goes deep.”
Taichi went very still. “You would steal from the shark?”
“I would take from the shark,” Yamato corrected, his voice low, “what he uses to devour everything you love.” He met Taichi’s wild eyes. “It’s a price he owes. For the scars on your back. For every one of your people he’s left to dry in the sun.”
A slow, dangerous smile spread across Taichi’s face, showing the sharp points of his teeth. It was not a pleasant sight. It was the smile of a predator seeing a path to its prey’s throat.
“Then we will take it,” Taichi whispered, the hum of the crevasse seeming to amplify his words into a vow. “And we will burn his nets with it.”
Outside, in the main grotto, the three eggs pulsed steadily, their light a confident, waiting glow.
