Chapter 2
Sheets of deep green seaweed swayed over the narrow mouth of the cave. Blue light peeked through the dark leaves, flickers of the vast ocean beyond. Stephen lay on his back and stared out the small mouth of the cave, through the seaweed that kept his little alcove hidden. Shadows danced across his upside-down face. There was barely any current in such a sheltered space, the water still and quiet against Stephen’s body, barely disturbing his hair. His green tail swished gently against the smooth stone floor of the cave, his body relaxed and hazy as he watched for movement beyond the seaweed.
There was a certain sharp silhouette he was looking for.
Stephen hummed absently, watching a silvery school of fish drift by outside. Normally, he would have chased after them, but he didn’t need to catch his own food now. He was cared for by the biggest, most dangerous predator in the sea.
All Stephen had to do was let the shark do anything he wanted.
Stephen bit his lip at the thought. He wondered distantly why his people feared being taken as a shark’s mate. There was no denying that sharks were terrifying, and he understood not wanting to be eaten, but this... this wasn’t so bad. The cave kept him hidden from other predators and his belly was always full of food from his mate. Lower down, his belly was full of something else from his mate, a heavy bulge where he was stuffed with shark eggs.
At the memory, a tingle ran down Stephen’s spine, the pink head of his sex starting to poke out of his slit. He chewed his lip and rubbed a hand over the full bulge. The shark would only deposit a few eggs each time, breeding him frequently, making his belly swell more and more. By now, Stephen was so plump around the middle that swimming was becoming awkward. It filled him with a warm satisfaction to know how much of his shark’s brood he was carrying, that he was being a good mate.
Stephen shifted his body against the smooth floor of the cave, remembering the firmness of the shark’s hands on his wrists, the hungry snarl of teeth, the stretch of a thick ovipositor stuffing him full. Sometimes the shark would breed him to fill him with more eggs, but sometimes he seemed to do it just for fun, blowing a sticky load of seed while Stephen gasped under him.
“Heh, little fishy wants more, huh?”
“A-ah, y-yes, please, my shark...”
Each time Stephen’s squirming body was impaled for the shark’s pleasure, he had a harder time remembering why he’d tried so hard to escape in the first place. Each load of eggs left him feeling heavier and sleepier and more eager to raise his tail for the shark’s thick member.
Stephen’s sex twitched again, sliding further out of his slit. He whined, staring out through the seaweed, waiting for his shark to return. He chewed his lip, breathing the predator’s name as if hoping to call him back.
“...Kaecilius...”
He could still feel the scrape of sandpaper skin against his sensitive tail if he closed his eyes. Stephen panted softly, sliding his hand over his pregnant belly, finding his fully erect member. He gave it a soft rub, squirming against the cave floor, panting as he fantasized.
He’d never been mated by a predator before Kaecilius, and he hadn’t been ready for how... intense they were. When Kaecilius wanted to breed, he would grab Stephen and hold him down and take what he wanted, powerful arms pinning Stephen in place while he was impaled with a thick, veiny, shark phallus...
Stephen whined, his tail thrashing against the cave floor, his hand stuttering on his sex. He slid his second hand down his tail, pressing two fingers against his soft pink hole. It was still sensitive and puffy from the last time the shark had bred him, right before Kaecilius left to go hunting. Stephen and whined as he slipped a finger into his slick hole. He closed his eyes, imagining Kaecilius’s rough hands, the low growls and sharp, terrifying teeth that would leave pink marks all over his body to let the world know who he belonged to. ...
“Naughty little fish.”
Stephen’s heart jumped and his eyes snapped open, his shaft jerking in his hand. As he stared upside-down through the mouth of the cave, he could see a dark silhouette framed against the shifting seaweed. Sharp brown eyes caught the dim light of the cave, running hungrily down Stephen’s vulnerable body.
“Don’t move,” Kaecilius ordered softly. He drifted closer with near-silent pumps of his tail. “You look delicious like that.”
Stephen obeyed, letting his hands drift away from his sensitive parts as the shark loomed over him, an upside-down grin of sharp teeth. Instinctive fear thrummed in his veins, but Stephen ignored it as the predator drifted closer. He soaked in each detail as it passed over him, the rough jaw and the smirk, the strong arms, the muscled body giving way to slate grey skin, a pale underbelly, and...
Stephen chewed his lip with a whine, his back arching off the cave floor. The shark’s phallus was fully exposed, thick and dark and ridged, hanging just over Stephen’s face. The knowledge of what it was going to do to him made Stephen’s heart race. His hole clenched around nothing, anticipating rough thrusts and the hot bulge of more eggs filling him up.
Kaecilius reached down, pressing strong hands against Stephen’s tail, framing his twitching member and pink, tight hole. Stephen could hear his chuckle. “You’ve gotten so obedient, little fishy.”
Stephen pressed up eagerly, already panting. “Because you make me feel so good.”
“Mmm. You used to squirm so much. I think I like you better this way.” Kaecilius brushed his thumb against the soft lips of Stephen’s slit where his fully erect shaft was protruding. “You’re so eager to be mated.”
“Nnnnh, yes...”
“You prey species are all the same. You turn into helpless little pleasure slaves as soon as a predator has their way with you. Nice submissive feast.”
“Ah—” Stephen shuddered as Kaecilius’s hand brushed over his sensitive tail, teasing near his twitching sex. The words made his face heat. “I-I’m not a...”
“You’re mine.” Kaecilius’s hand wrapped around Stephen’s shaft, giving it a soft stroke. His fingers prodded the tight pink hole just under it. “Aren’t you?”
Stephen’s face was red, whining as the shark played with his body. “Y-yes, I... I’m yours.”
“Good.” Kaecilius’s tail lowered, his shark member falling against Stephen’s flushed face. “Open your mouth, pet.”
Stephen twisted his face away in surprise. “Wh-what?” The thick shaft bumped his cheek, heavy and throbbing. He panted against it, whining as he felt powerful hands pinning his tail to the floor. “B-but that’s not how... you can’t breed my mouth...”
The shark chuckled, his tail shifting, his shaft bumping Stephen’s lips. “It’s still a sweet, tight hole I can stuff. Now open up.”
The snarl of threat in Kaecilius’s words made Stephen go tense with instinctive fear, his mouth falling open. As soon as his lips parted, Kaecilius’s thick member pushed past them, his ridged shaft sliding into Stephen’s mouth and muffling his startled grunt.
“Mmmmh...” Kaecilius let out a low noise of pleasure. “That’s it, you know better than to deny your predator. Sweet, scared little prey... You’ll let me do anything to you, won’t you?”
Stephen whined around the phallus in his mouth, his eyes wide, watching the thick, ridged member slowly sink into him. It felt weird, slippery and hot and musky, and it made his face heat to know that a shark was using his mouth like it was a breeding hole. His sex twitched against Kaecilius’s hand, his full belly bumping the shark’s muscled chest. Kaecilius’s tail shifted, making shallow thrusts into Stephen’s mouth, the ridges on his shaft bumping past Stephen’s lips. All of Stephen’s senses screamed predator, he could taste the danger on Kaecilius’s skin, but all he did was shiver. He couldn’t believe he liked this. Each thrust eroded his protest, pushing a little deeper.
Kaecilius growled eagerly, the thick head of his member throbbing as it squeezed into Stephen’s tight throat. “Nnnh yes...”
Stephen groaned, his eyes hazy as the shark claimed his mouth in slow, hungry thrusts. He could feel the shark’s thick phallus stretching his throat the way it would stretch his other hole, stuffing him full as it pushed deeper.
“Mh.” Kaecilius was panting. “You’re a real natural at this... I’m gonna use this sweet mouth more often. Feels as good as breeding your other hole.” His thumb brushed over Stephen’s clenched, pink entrance. “...Well, maybe not quite as good...”
Stephen squirmed in alarm when he felt soft, slick pressure against his hole. Kaecilius chuckled and dragged his tongue over Stephen’s tight, pink entrance again, still rolling his hips. His stubble scraped against sensitive skin.
“This is where you prefer it, huh? Your sweet pink hole is always ready for me.”
Stephen’s nose nearly bumped against Kaecilius’s tail with each thrust. He could feel the shark’s phallus deep in his throat, thick ridges at the base rubbing his tongue with each thrust. His head was spinning, his hole clenching against the rough swipes of Kaecilius’s tongue, his tail pinned in place by the shark’s strong hands. Every other thought was overwhelmed by the desire to be mated, to be claimed in every way a shark could claim its prey.
“Nnh—” Kaecilius groaned and his hips stuttered, his next thrust harsher than the last. “Oh yeah, I’m gonna breed that tight throat...”
A strangled noise slipped out of Stephen as he felt the shark’s member throb in his mouth, felt the distinctive hot gush of predator seed. It pulsed down his throat, so deep he had no choice but to swallow it. Stephen gagged, squirming once as Kaecilius thrust again, feeding him another hot gulp.
“Mmmmh—” Kaecilius’s fingertips dug into Stephen’s tail as his hips jerked. “Oh yeah, that’s a nice virgin throat...”
His phallus dragged out slowly, pulsing one last time just before it slipped free, a harsh jet of seed against Stephen’s tongue. Stephen swallowed obediently, gulping frantic breaths of cool water as Kaecilius’s shaft finally slid out of his mouth.
Kaecilius’s grin was sharp in Stephen’s upside-down vision. “Hope you liked your meal.”
Stephen caught his breath, his throat still tingling from being used. He could feel the warmth of the shark’s seed in his belly. He was so dizzy with need he couldn’t even keep the lust from his voice. “Y-yes, I l-liked it...”
“You sound needy, little fish.”
Stephen whined, his tail wriggling in Kaecilius’s grip. “Please... I want more, want you to breed me again...”
Kaecilius grabbed Stephen’s tail in a rough grip, twisting as he grinned over his shoulder. “Roll over, incubator. Time to do what you were made for.”
Stephen yelped as Kaecilius’s rough grip shoved him face-down against the floor. His large belly bulged against the smooth stone, the eggs inside him jostling. Kaecilius’s powerful tail beat the water, gusting against Stephen’s skin as he reoriented himself behind the trapped merman.
“Ah—” Stephen gasped as his tail was grabbed and lifted. He could feel powerful arms hugging it to Kaecilius’s chest, keeping him pinned against the shark’s body. Kaecilius’s phallus was still erect, bumping against Stephen’s own.
“That’s a good look on you, little fishy.”
The now-familiar tip of the shark’s phallus pressed against Stephen’s eager hole. He moaned, wriggling in Kaecilius’s grasp, his entrance eagerly opening for the predator’s shaft. His heart hammered like it always did, his instinct trying to warn him against the dangers of an aroused predator, but it was never enough to overwhelm his lust. Stephen gasped against the cave floor as Kaecilius pushed inside, one thick ridge at a time tugging Stephen’s well-used hole.
Kaecilius let out a pleased snarl as his tail bumped against Stephen’s swollen belly, his ridged shaft buried to the base. “Mmmm, always so nice and tight...” He nipped at Stephen’s tail, drawing a startled gasp from him. “That’s right, squeeze for me.”
The swell of an egg pressing against Stephen’s hole had him moaning. His body had grown accustomed to the constant breeding, his hole eagerly welcoming the thickness of another egg. He felt it slide down the shark’s ovipositor inside him, deposited deep in his belly with the rest of Kaecilius’s brood. More eggs followed, one at a time, each one straining his stuffed hole before filling his belly just a little more. Stephen panted against the cave floor, helpless in the shark’s grasp, whimpering in submissive pleasure. Each egg bumped against places inside him that made his sex throb, made his body clench around Kaecilius’s shaft.
Kaecilius was panting in obvious pleasure. His powerful arms kept Stephen’s tail pinned in place, keeping him exposed for breeding. “Nnh, you might be the hottest piece of tail I’ve ever had...”
The next egg made Stephen cry out in need as it slipped into his belly. He was so heavy he wasn’t sure he’d be able to move, but he still wanted more.
“I’ll keep you for next breeding season” Kaecilius say. He bit Stephen’s tail again, harder, making him squirm.
Another egg pressed against Stephen’s stretched hole. A weak, pleasured whine was the only noise Stephen could make. His belly was so full that it pressed against the floor of the cave even with his tail hoisted over Kaecilius’s shoulder. His throbbing member bumped against it, a constant reminder of how full he was, how swollen with eggs, nothing but a helpless vessel for a predator to breed.
Kaecilius growled, his sharp teeth nearly breaking Stephen’s skin. Stephen squirmed in alarm, writhing on Kaecilius’s shaft, jostling the load inside him. The last egg slipped past his stretched hole, bumping against his pleasure spot as it slid deep, and Stephen’s cries echoed in the small cave as he came. His sex twitched, spurting his own seed against his swollen belly. His hole clenched around the dominating girth of Kaecilius’s shaft, spasming in pleasure. Kaecilius growled in obvious enjoyment, biting harder at Stephen’s tail and drawing one more breathless gasp from him before the merman went limp in his hold.
Stephen whimpered dizzily, his cheek resting against the cave floor, his belly distended with eggs. His sensitive sex was still throbbing, his tail quivering against Kaecilius’s powerful body. Pleasure had melted him, leaving him limp and compliant.
A sudden, sharp thrust drew a wrecked cry from Stephen’s throat.
“Mmmh—” Kaecilius panted against Stephen’s tail as he dragged his ridged phallus out and slammed it back in. “That’s it, not even gonna wriggle, huh? Just gonna let me take you as hard as I like.”
Stephen gasped against the floor of the cave, his hands splayed against it as the shark pounded his used hole. He could feel sharp teeth pressing against his sensitive tail, hear the vibrations of Kaecilius’s growl. He was too dizzy with pleasure and heavy with eggs to resist as the predator roughly thrust into him. His small, tight hole was growing sore from the pounding, his pink member oversensitive from the stimulation, twitching and throbbing as Stephen gasped and trembled against the floor.
“Say my name, little fish.”
Stephen whined as Kaecilius yanked his tail. “K-Kaecilius!”
“Mmh—” Kaecilius groaned as he thrust. “Hope you want more seed in your belly. This little breeding hole feels too good...”
“Y-yes—” Stephen cried out as Kaecilius’s tail slammed against his, the rough ridges at the base of his member forcing open Stephen’s hole. “Y-yes, g-give me your predator seed, breed me—”
Kaecilius snarled and nearly dragged his entire member out of Stephen’s wrecked hole before slamming it back in. It throbbed as it filled him up, hot and sticky and creamy. Stephen moaned dizzily against the cave floor, squeezing around his predator’s phallus. He could feel slickness coating his insides, oozing between the eggs.
“Mmmmm...” Kaecilius slid his ovipositor out slowly, thick veins and ridges dragging past Stephen’s pink entrance. The head finally popped loose, and Kaecilius chuckled. “Heh. You’re gaping.”
A possessive thumb pressed against his sore hole, testing the give, and Stephen whined against the cave floor. He tried to clench against the pressure and couldn’t. He shuddered when the shark’s thumb pushed inside, slipping easily into him.
“That’s how a merman should look. Full of eggs and loose from breeding.” Kaecilius slipped his thumb out gave Stephen’s tail a smack, drawing a yelp from him. “Don’t you think so?”
Stephen gasped when Kaecilius smacked his tail again, palm slapping against his used hole. “Y-yes, my shark!”
Kaecilius’s hand slid down Stephen’s back, a gentle stroke. Stephen let out a soft moan at the touch. Kaecilius let go of his tail, and Stephen gratefully rolled onto his side, letting his tail flop against the smooth cave floor. He panted as he stared down at how swollen his belly had become. So full... He rubbed a hand over it, biting his lip.
Water currents tingled along Stephen’s tail as Kaecilius swum behind him. Kaecilius lay down on the floor behind Stephen, spooning against him and purring into his neck. Their bodies were pressed together, the shark’s powerful arms holding Stephen close. Stephen snuggled back against him, dizzy and sleepy. The fat head of Kaecilius’s phallus was still poking out of his slit, and Stephen could feel the slick bump of it against his back.
Kaecilius rubbed his hand over Stephen’s swollen belly. “You’re getting big,” he teased.
Stephen bit his lip. “F-full of your eggs.”
“Heh.” The shark nipped Stephen’s neck. “Nice fat belly, just like you should have.”
“Feels so good...”
“That’s my mate. So proud to be mine, aren’t you?”
“Y-yes.”
Kaecilius nuzzled into Stephen’s hair. “Get some sleep, little fishy,” he murmured. “I’ll breed you again in the morning.”
Stephen’s sex had half-receded into its slit, but it gave a little throb at his shark’s words. He wriggled back against the shark’s powerful body, letting out a content sigh and closing his eyes.
Belonging to a shark wasn’t so bad.
