Chapter 1

A deep rhythmic rumble dwelled in the depths of the ocean, where two beasts of colossal proportion slumbered. Had the light that resided in their forms not illuminated the abyss around them in deep blue and pale white, all would be black.

The slightest movement of the two came to the world as a brief and faint tremor, as their bodies pressed to the bottom of the cavern floor.

The bearer of the pale lights was that of a dragoness, though designed to reside in the deep waters of the planet. Her scales shone brightly, each individual plate in her natural armor lined with a glossy baby blue. She was almost equal in size to her lover, whom held her from behind as he snored softly; a shark pony hybrid of megalodon size with lines and swirls all along his body and mohawk of a mane glowing a deep blue in a vessel of near charcoal black.

Within her sleep, she dragged her claws along her chest, as if to scratch an itch. This motion caused the shark to grumble under his breath, squeezing her tighter, which in turn, caused her to awaken.

Light blue eyes opened to the darkness, and her mouth, once left hung open, snapped shut, only for a smile to curl on her muzzle as she looked down at his forelegs wrapped around her form.

Her tail swished through the high pressured liquid, where surface dwellers dared not venture, and traced along his slick, muscle toned flank. With his body pressed firmly to her back, her wings stayed folded to such.

"Good morning, Megalodon." She spoke in a purr, fluent and coherent despite the ocean's attempt to obscure.

Again, he grumbled.

"Does it have to be morning...?"

She chuckled before turning her body to face him. As he loosened his grip for her to do so, her wings flared out with grace and cocooned around him, pulling herself closer to him so their muzzles could meet.

Dark blue eyes in a realm of black revealed themselves to her as they stared intently at one another, and with a gentle kiss to his lips, and a brief flick of her tongue to one of his many rows of teeth, she spoke.

"Time knows no favors, love. We have a hunt today."

He closed his mouth and narrowed his eyes in a loving manner, smiling.

"I love you, Leviathan." He nuzzled her nose in affection, and she giggled.

"And I you, Megalodon." She then looked around, scanning the darkness, before returning to him. "And I love you, Sawtooth... wherever you may be."

To the sound of her name, his eyes shot up, now darting to and fro in search of her. He quickly arose to his hooves, looking down at where he once laid.

"Oh no... No, no, no!" He spun in circles, his tail curving with the momentum and nearly striking Leviathan's face, had she not backed up. "Sawtooth!" He called out, to which the cave they slept in shook.

"Lower your voice, dear. We don't want another cave in, like with our old home."

He paused and looked at her with grave worry in his eyes.

"Did... Did I crush her...? Ohhh no..."

She arose and looked down at where she had been slumbering, only to find both her space, as well as Megalodon's, was left void of any splattering...

... Of blood, anyways...

Other bodily fluids took place from last night's activities.

"Megalodon..." She put a claw to his chest and took in a deep breath. "Caaaalm. Remember last time. You almost gave yourself a heart attack."

He sighed and shook his head, running a hoof along the blue spiked collar around his neck, as if it were an anchor of his feelings.

"Right... Right. I just..." Again, he sighed. "She's so..."

"Fragile?" Leviathan quipped with a wry smile.

Slowly, he nodded.

"I'm terrified of hurting her."

"As am I, dear. But you forget..." She moved her claw from his chest, navigating up to his mane and parting the differently shaded blades, revealing to her, a dark grey shark pony, much smaller in size compared to the two, who laid on her stomach with her chin perched in both forehooves as her tail swayed back and forth. Her brown mane was groomed back.

"Hi." The small shark pony grinned a row of shark teeth as she squinted her eyes up at Leviathan.

Leviathan rolled her eyes, but shared in the amusement with her smile.

"Come on, now. You keep scaring Megalodon when you do that."

"Well, now, I couldn't resist." Sawtooth giggled as she swam out from the jungle of his mane, dancing through the waters with spins and twirls. "His mane is warm. Plus, I love hearing how much you two adore me."

Megalodon sighed with relief as the fin of his tail came around, blocking her trajectory and causing her to bump against it. With a thud, she 'oomf'd' against his fin before he brought her closer to him.

"Well, my little Sawtooth..." Ever so gently, he nuzzled into the back of her head, to which she giggled. "You don't need to scare for us to show how much we love you."

"I think last night was proof enough." Leviathan giggled as a shade of red grew on her face. "For both of us..."

Sawtooth blushed, shifting her body so her front was pressed to his muzzle, with which she kissed at his lips, despite her small size.

"I love you too, Megalodon." She purred under her breath, before swimming up to the top of his nose and laying atop it, looking deep into his eyes. "I love you both."

Megalodon chuckled and closed his eyes before his collar grew brighter. Wisps of light emerged from the spikes, forming his shape to match her size, while his real form stilled, as if in an eternal slumber.

His exact physical detail, minus the size and collar, swam up to her and laid beside her atop his own muzzle. His tail curled around hers as he held her close and nuzzled into her cheek carefully.

She turned her head to face him and smiled as their eyes met. She inched closer as he did, and with deep passion, their lips locked with each other; eyes closed instinctively to the contact, and softly, she moaned under her breath.

In turn, he chuckled behind the kiss before they broke it. In a hot mess, she huffed.

"R-round ten?" She asked nervously.

"More, eh?" Leviathan giggled.

Sawtooth grew bright red and averted her eyes.

"Well, he does have that effect on me..."

"On both of us, dear." Leviathan corrected with mirth.

Megalodon pondered for a moment, licking his lips to the idea of having dessert for breakfast. He could already smell and taste it coming from her betwixt her legs.

"Hmmm..." He nibbled at her ear, with which a coo escaped her. "Are you sure you can handle another...?" He whispered.

"A-at this point..." She panted. "I need it..."

A deep rumble sounded in his throat before he parted from her ear, drifting backwards with a hungry look in his eyes.

"Very well, dear..."

His tail released hers, but within seconds, a forehoof got a hold of it, raising it up as his other kneaded into her firm flank. Small gasps of pleasure escaped her from the attention he offered.

"Mmmh..." She murred. "M-Megalodon..."

Her nethers winked to him upon reveal. He smiled at the delectable view and moved his muzzle in, kissing the cheeks around her lips with the occasional nibble to elicit a gasping moan to his tease.

A slow trail of his kissing moved along her flank, inching ever closer to her treasure. All the while, she heavily anticipated his arrival. Her tail draped along the top of his head and across his back, twitching to the sensations he supplied to her.

He kissed the corner of her fold, the scent of her beginning to overwhelm him with desire to delve his tongue deep within her. It was a challenge for him, a challenge he failed, no less, to not leave behind a lapping of his tongue across the corner of her fold, getting a brief taste of what was to come. The taste was addicting, driving his dual members to unsheathe from between his legs.

He pressed his nose to her, taking deeper within, her scent. Driving him into a lustful frenzy for her.

"Rnnngh..." He growled under his breath between inhales. "Ohhh, Sawtooth..."

"M-Megalodon..." She moaned more frantically. "Fuck... t-take me..."

He chuckled deeper, giving another lick...

Leviathan watched silently, her own juices beginning to excite as she laid on her side, dragging her claws along her slit back and forth.

His muzzle moved along her nethers, briefly parting her folds and getting a rich scent and a sharp gasp from her...

... Before kissing at the other corner.

She huffed in annoyance at his tease.

"Me-Megalodon, you... y-you..."

"Hmmm?" He purred in delight at her suffering as he kissed and nibbled at the flank opposite of where he started. "What's that, dear? I can't quite hear what you're saying."

"Y-you're so m-mea-AGH!"

Without warning, both forehooves locked down on either side of her flank, pinning her down as his muzzle pressed firmly into her nethers, lapping up at her slit.

She cried out in shock and pleasure as the sensation of his tongue beginning to penetrate shot through her body.

"Mmh! F-fuck! Ah, fuck, Megalodon!"

The calling of his name drove him further into a lustful frenzy, fighting himself not to stop what he already started and rut her. He wanted to taste her... No matter how many times he had done before, he couldn't get enough. Half of the reward was her joy.

Leviathan began moaning softly under her breath as two claws slid inside her, pushing in and pulling out at an even pace as Megalodon stroked his tongue up Sawtooth's sweet marehood. His tail swayed to and fro between his original vessel's eyes as his cocks throbbed, already leaking pre cum into the ocean around them.

His muzzle pressed deeper into her, before parting her lips for entry. With a cry of ecstasy as his muzzle was buried deep within her tunnel, his tongue shot out from his mouth, unable to hold back any more than he already had. With feral abandon, he lapped up her slick velvet walls, taking in the juices and delivering it to his throat, with which he downed; his throat worked effortlessly to drink of it as he continued to go for more.

Leviathan began growling more noticeably as she began to quicken her pace to the show happening before her, baring her fangs and flaring her wings as her tail swished across the cavern floor.

His tongue met the end of her stretch, and the jolt of her body and the sharp gasp left him a signal that he hit the right spot, and so he continued to tease at it. Tracing his tongue around it, exploring every little bit of it.

"A-aah! Megalodon! Fuck me! AH! I'm-nnngh!"

The other half of his reward was soon to be redeemed as she arched her back in her fit of cries.

Her velvet tunnels tightened around his tongue like a snare as her cries amplified to near fulfillment, keeping him locked in place moments before her juices spattered along his muzzle, on his tongue, and within his mouth. He murred softly at the taste of his work, and with her climax nearing its end, her walls began to loosen ever so gradually, occasionally twitching as he lapped up the remaining fluids.

Upon pulling out, he licked his lips clean and smacked them, before delivering one final kiss to her folds.

"Mmhh..." Sawtooth giggled, looking over her shoulder at him behind the afterglow. "Fuck, that was amazing..."

He chuckled as he climbed atop her, gliding along her form before coming to a stop inches near her muzzle. His members throbbed against her back as he held her close.

"You say that every time." He smiled tenderly, locking eyes with her.

She moved in, locking lips with him once again and getting a taste of herself. After parting, she giggled again before replying.

"And I mean it every time."

"Of that, I have no doubt." His smile brightened before he looked up at Leviathan, who still pleasured herself slowly after her climax had already released; her eyes now shut as she was lost in her own world. "I suppose we should start the hunt now."

Sawtooth laughed as Leviathan slowly opened her eyes in a half-lidded gaze, looking at both of them.

"Ohhh no. We're not done yet." Sawtooth murred. "I feel you. You need some release too. You know the rules."

"We a-all get off..." Leviathan moaned as she pulled her claws from her nethers. "Or no one does..."

With a tint of red enveloping his cheeks, he chuckled and nodded. "Very well. How do we want to go about this?"

Lustful eyes and a sharp grin of dragon teeth focused intently on him from across the cavern as Leviathan replied.

"We're hungry too, Megalodon..."

The idea alone sent a thrill run throughout his body. With a smile, he pressed his lips to Sawtooth's cheek before closing his eyes. His form dissipated into light, which then returned to the collar around the neck of his real size.

His eyes opened as his body caught up with the desires they had in mind for his satisfaction. Already, his dual members extended from their sheath.

Leviathan swam slowly up to him as Sawtooth went down between his forelegs, laying on her back and eyeing the prizes that throbbed before her.

Before the colossal sea dragoness reached her destination, she swooped down, dragging the tip of her tongue along Sawtooth's form down to her nethers. A gasp of surprise overtook her as Leviathan murred softly.

"Megalodon's lucky." She spoke seductively. "I wish I could taste more of you, Sawtooth..."

"We're just as lucky to have him." The small shark pony replied, to which Leviathan giggled happily.

"Oh, definitely..."

Megalodon blushed as her tail wrapped around his neck; her muzzle inched near both of his eager erections, and with her tongue, coiled around them, binding them together to get the full package.

Slowly, her binding pumped back and forth, causing a soft moan to escape him.

She suckled on the tip of one for but a moment, before she parted and looked down at Sawtooth, who watched the show, occasionally eyeing Leviathan's treasure.

There wasn't much ponder before the sea dragon twisted around and lied on her back, spreading her legs.

Sawtooth, now smiling wider at the invitation, swam up and rested on her belly.

"Megalodon, love." Leviathan said before nuzzling one of the erections above her.

"M-mmh... yes?"

"Can you do me a favor and lick me clean?"

A deep chuckle escaped him as he eye'd her slit.

"Oh, with pleasure..."

With that said, he lowered his head and began to lap his tongue across her entrance. A deep purr escaped her moments before she coiled her tongue once more around one of his cocks, taking it in her mouth and pumping at it. A free claw gripped his other and began pumping at that while another gently massaged his balls with care.

Sawtooth went for another round, stroking a hoof along her pussy rapidly as the show played out before her, rising and falling with Leviathan's stomach as she breathed in and out; taking in Megalodon's scent as she suckled on him.

The two giant creatures growled and moaned deeply as they pleased one another with love and lust. A deep heat grew from within Leviathan's stomach and chest, rising to her throat as her wings wrapped around his back and forced him down.

In doing so, his cock slid down her throat to the hilt, causing her to briefly gag on it before she resumed bobbing her head back and forth along his shaft. A deep growl sounded in his throat in response, mixing with moans that gradually grew more intense the more she went at it.

His other cock, meanwhile, resided on her chest, aimed directly at Sawtooth's form as it pulsated. She spread her legs farther apart as she broke through her entrance with her forehoof, delving into her tunnel at the sight and sound of her lovers having their way with each other as they did with her.

Leviathan's grip squeezed gently at his balls, feeling every part of them as her mouth went from tip, past the ring, and to the base of his excitement; her tongue slithering and snaking around its length all the while, mapping its terrain.

Pre cum leaked from both outputs, and with his size, gave the equivalent of ten to fifteen surface dwelling stallions shooting full loads. This left a swirling puddle along and around Leviathan's chest, slowly drifting closer to Sawtooth's proximity. Despite it not having yet reach her, she could taste just the start of it on her tongue as she panted and moaned, rapidly assaulting her tunnel for another release.

The dragon's wings pressed more firmly into his back as his tongue slid within her, lapping at her walls for the excess that hadn't breached.

With her aggression in forcing him closer to the ground, she had buried her face completely in his balls, forcing herself to take in the full scent as she choked on his dick. She moaned deeply, her throat vibrating and closing in around his extension as she worked tirelessly to pump his juices from him. Feral hunger began to overwhelm her as it did him, as so, as she had slid him further within her, slowly suffocating herself on him, he dove his tongue as far as he was able before his muzzle sank into her.

Leviathan's stomach rose and fell more rapidly as did her motions on both dicks. Pumping and squeezing with mouth, throat, and claw, and loving every inch, every second of it.

Sawtooth let out a series of soft cries as her climax was nearing; the salty taste of his pre now washing over her. Her mind was begging for more.

Soon, she would get her wish, as their frantic breathing and ecstatic cries told of their climax at a near approach as well.

Tip to hilt, Leviathan massaged both, gagging and sputtering. Drool sloppily spilled from her mouth with each return.

And around her tightened throat, around her clenching grip, she knew when his members both stayed flexed from their throbbing state, that he was mere seconds away.

With that warning, she shoved her face in as deep as she could, causing Megalodon to scream in orgasmic bliss deep inside her as she too, was already releasing her load; spattering over his muzzle in large quantities, and in waves.

While her mouth stopped, her claws continued.

A large spurt of hot semen flooded into her, with which she began to swallow rhythmically, as more and more came. Her claws, gripped around his shaft, continued to milk him dry as simultaneously, both released their waves.

The first round shot over Leviathan's chest just as Sawtooth was screaming from her next release. The moment her orgasm hit, the second wave of cum gushed over her, completely dousing her in Megalodon's hot, fresh seed, from top to bottom, giving to her the rich scent and taste of him.

Then the third wave came, drowning her in it.

Fourth.

Fifth.

Sixth.

Megalodon, had much to give both of them...

Seventh.

Eighth.

Leviathan's belly slowly began to expand from the fill she was being fed. She slurped and gulped, sputtered and moaned as he filled her up.

They were both getting more than their fill.

The ninth throbbed release was the last, this one being about half of what the others were producing.

The three of them were more than satiated.

Leviathan slowly gulped down the remainder of what she couldn't down right away. Sawtooth, absolutely buried in his load, had the time of her life taking in what hot, messy slop she could as she rode out her orgasm to the end.

Megalodon, as he pulled out of the dragoness' pussy, panted in the afterglow as she slowly continued to suckle on him, knowing his two lovers were feasting happily on his seed as he did, their juices.

Leviathan's wings collapsed to either side of her as her claws did. She murred softly with his cock nestled in her mouth, which was now left hung open. Slowly and carefully, he pulled out, turned around, and noticed the massive mess he left over not only Sawtooth, but Leviathan's body as well, as his load reached as far down as her nethers.

It was then he noticed he had shot himself in the throat with his own. With a happy chuckle, he wiped it away with a hoof and licked it clean, before lying down beside his sleeping dragoness. He took notice in her expanded belly and spoke under his breath.

"Guess we're not hunting then." He laughed softly.

Sawtooth, completely drenched in his seed, swam up, panting and smiling up at him. She was starting to look a little inflated too.

"Uhh..." She hiccupped, covering her mouth with a hoof for a moment. "L-little help?" She removed her hoof, licking her lips. "I can't really t-hic!-take it all, what with being... my s-hic!-size." She laughed nervously.

With a laugh, he swiped a hoof along the sleeping dragoness's belly, gathering some of his offering, and began to lick it clean.
