Instinct drives the world, even our complex human minds are drawn by an incessant undercurrent of instinct. In this, our hero has long forgotten how to be a person and when the instinct rises he has no qualms about satisfying his needs.


Years ago he had lived as a man on the surface. He went to work, he wore a suit, he came home, he went to the bar, he even played sports. But that was a lifetime ago, a memory so distant it seemed like a dream. A string of crimes and the police fingered him, he did the only thing he thought reasonable, he fled the country--hell, he fled land all together.

Today he was more beast than man, inhuman, cold, and mindless in action. Hunger drove him up from the cold depths of the ocean, hunger for something he had not tasted in decades. The sea was his home now, its darker beasts familiar to him, its most potent dangers no threat. Here in the cold deep waters he was king of his domain.

With a powerful sway of his tail and thrust of his legs he cut through the water. Cold black eyes scanned the surface, spotting the telltales of passing boats, dolphins, and warm water fish. He was close now, a port city he had once known long ago with its constant stream of ships. Then west a few miles he found the coral shoals he sought. Once a life time ago, as a child, he had come to them and been enraptured by the brilliant life below the crystal waves. Today he felt nothing for them as he passed clumps of anemone, random urchins, and brightly colored fish.

The hunters instinct in his gut told him where to seek, reminded him of the divers he saw as a youth. They came to observe the beauty under the waves. Ahead he saw a group, five, too many to comfortably take. He waited patiently as the unwary divers drifted about. Minutes passed but eventually his patience was rewarded as one, a small female parted from the group following a school of fish. She swam with grace and experience and his cold eyes appreciated the delicate curves of her form, young but not too young, small but muscular. She would do.

He waited only long enough for her to disappear behind a mound of the reef, and then he darted out. He swam like lightning, darting through the crystal water faster than any eyes could have tracked him. He caught her unaware, her back to him with hand out stretched to a fish; which startled away at his approach. His hands encircled her neck first, a vice grip that cut off her air and the flow of blood. A moment passed, she struggled, gaped, thrashed, then eventually went still. Carefully he replaced the mouthpiece between her lips and checked to be sure she still drew breath from it. She did though with occasional coughing fits as water trickled between her lips.

He wrapped her in his embrace and pulled the mask away from her eyes. She was rather cute, with a button nose and a spattering of freckles under carefully bound red hair. Her eyes were closed but he had caught a glimpse of green in her terrified thrashing. She would do he decided, and with that he shot off, dragging her unconscious form along, far out towards the deep ocean and the sharp underwater cliffs of which he made his home.

When she woke again there was only a dim light, like that of the sun through storm clouds. He had dragged her deep, so deep in fact that her body was struggling to withstand the pressure. With blurred vision, a splitting headache, ruptured ear drums, and a throat that felt horribly bruised, she tried to make out her captor. He was gray with hide as rough as large grit sand paper. His body was muscular and sleek, obviously made for swimming; a great white shark in the guise of a man. She had heard of shark anthros, though never before had met one.

His grip upon her tightened as she moved, preventing her from squirming free. His head dipped to peer down at the small girl, black eyes taking in her bewildered expression, an edge of terror in her eyes. He grinned at her, as if to disarm, but his mouth was filled with rows of shark teeth and his smiling pliable lips did little to disguise that fact.

No matter, he decided, she would come around or she wouldn't, either way he had claimed her as his and she would never be able to escape. Deeper he swam, plunging them both in to the cold darkness below. By now the light of day was little more than a memory and he navigated by the vague dark outlines of the cliffs. Deeper still and he arrived at the prepared cave. He had found it years ago, a pocket of air fed by under sea vents. It was unpleasant, but she could survive there until he was done with her.

At last he found the entrance and made his way up the cave. Her fists beat at his chest as the darkness enclosed: it was a futile gesture. At last they broke the surface and he relaxed his grip. She jerked away with a sob and backed to one side of the chamber. It was too dark to see but he could hear her perfectly as she coughed water up from her lungs and sobbed in fear, "Ledge, left." He told her shortly and climbed upon it himself. It was still submerged, but the water was shallow, only a few inches of depth.

A light flared as she held it up and exposed the large dark cavern around her. The air was misty, with a sulfurous haze and a stench like rotting fish and eggs. It was breathable, but it made her lungs ache and the foulness of it made her cringe, "Why..." She started, coughed, then started again, "Why did you bring me here?" She demanded with the light aimed at him.

He stood up and walked toward her, muscular form towering over her by almost three times. He was huge, old, and barely remembered enough civilization to understand her, "Mine." He told her and took her tresses in his hand. She dangled from his grip with her hands latched on his wrist, trying to relieve the aching pull. Her legs kicked but only her toes splashed through the shallow water.

"Oww..." She cried and begged, "Let me go."

He said nothing more as he carried her deeper in to the cavern, toward the shallowest part. There he dropped to his knees and laid her body out in the water with her head raised above on a mass of stone. Buckle and strap gave way under his fingers, tearing where he couldn't unfasten. Her wetsuit was ripped open to expose her freckled bare skin and there he explored with hands so rough they scraped raw where they touched. "Mine" He insisted again as his hand pressed up between her tightly closed thighs.

"Oh god..." She gulped. Her body drew away instinctively from his cruel touch but was helpless against his strength. He released her hair at last to her... momentary, relief. They closed again on her knees and almost gently parted them. Her exposed sex at last revealed to him in the light of the fallen torch; he smiled.

Upon his lower stomach, what appeared to be two fins shifted forward slightly and outward. The tips of them bulged and rolled open like foreskin with insides swelling to be a dual phallus; pressed together and erect with two tapered tips. Angled downward as they were, it took him a moment to position her struggling form correctly, but at last his cocks kissed her entrance. She was as dry as could be for some one submerged in the ocean, there was no arousal in her, in fact there was only deep visceral revulsion at his every touch--which he paid no mind.

That first thrust tore her virginity, the slimy tapered heads as hard as spears. She arched her back in pain and an attempt to withdraw her hips from his insistent hunger; as futile as before. Trapped deep under the ocean with barely a breath left in her tank and only hard cave walls to protect her--he raped her. The hide upon his phalluses were covered in the same sandpaper scales as the rest of him, only the very tips were free of them; pink, oozing, vulnerable and buried to the hilt in her torn sex.

At that first thrust her labia stretched wide, her hymen gave way, then lastly a split formed along the lower wall of her sex to make room for him. About her the water was stained red, her belly was splattered with her own blood. A single penis would have been enough to tear her, but he used both and seemed to grow even more excited with her screams of agony. Upon his withdrawal that rough hide was even worse. One direction it was at least tolerable, but the other it caught at flesh like velcro. Her inner intimate skin was shredded; never before had it been touched, by no man or even herself, and now it was ruined.

Again he thrust, harder, the hunger stronger than before, stronger than he could ever remember it. The smell of blood excited him further, bringing a hunting frenzy to his mind as he claimed what was his. Over and over, each time he bottomed out in her ruined belly, he snarled, "Mine." It wouldn't be long though, it was decade since his last woman, decades since he had even touched himself. After no more than five minutes he felt himself peak suddenly. His body grew rigid and a trembling sigh issued up his throat. A moment later his thick inhuman seed spilled in to her torn depths, one thrust, two, a final, and then he pulled free and slipped back in to the water. The feeding hunger still burned in his mind so he fled, not wanting to endanger what was his. In to the darkness he fled, a trail of semen still spitting from his dual cocks, a milky trail leading from the cave.

Abruptly alone she knew not what to do, what to think. Since her capture she had thought of nothing but the immediate discomfort, fear, or her own impending doom. Now she was alone with her thoughts and her aching flesh. With a groan she crawled through the water to find her flashlight and inspect herself. It wasn't as bad as she feared, she would need a while to heal, that was sure, but she wouldn't bleed to death. Then with that realization she felt a strange sense of sorrow, "That... wouldn't be so bad, would it?"

She found her air tanks and checked the gauges, nearly empty. She couldn't imagine how deep she was, but there wasn't more than five minutes of air left. At that she nodded and sat back in to the cold water, "Yes... Maybe I should." She mumbled. A hand felt around until she found the belt for the tank but her knife was gone, hopelessness overwhelmed her. Then a sudden pain in her gut pulled her inward and her hand came away coated in semen and blood. Fluid gushed out of her with sudden force as another seizure of agony gripped her frame. She fell over and squirmed back and forth; worse than the worst gas pains or menstrual cramps coming in waves.

He returned to find his mate sleeping. Her body had changed a little; the smoothness of her pubic mound with no fur to be seen; the hint of scales spreading up her belly. His hunger returned once again, and he took her there, bodily dragging her against him and thrusting in a single fluid motion. She woke to the sudden pain of his penile intrusion. Her bruised and scabbed cunt ripped open again freshly; pink stained the water once more.

She screamed at him, "Stop please!" but he paid her no mind. She looked upon him and those cold black eyes staring through her. A shiver that had nothing to do with cold trembled up her spine. He was a shark, she knew this, but never before had it struck such terror in her soul. He felt nothing for her, no love, no pity, no affection, not even hatred and he never would. She was little more than the fish he ate. 'mine' she mouthed the word and truly felt it for the first time. Possession, not love, not romance, not trivialities of social grace; Mine he had said, and meant it.

For days she endured it, waking up from the middle of a nightmare to find him using her. Being thrown to the ground and pinned when ever he felt the need. Her body was changing too she realized, rough scales were spreading over her pubic mound, thighs, and belly. In truth she was thankful for them, they protected her from the roughness of his mating at least a little bit.

She ate only raw fish, it was all he brought her. At first she had turned her nose up at it, but on the second day as hunger pains warred against disgust and the rest of her suffering--she surrendered and feasted. It wasn't near as bad as she feared. But even though he fed her, she always felt hungry. Her cheeks grew shallow and her breasts shrank while muscles atrophied. But all the while her stomach grew. She was seeded well and he seemed pleased. Though pregnant the rapes never stopped and to her humiliation she welcomed it. His insatiable lust was the only thing that broke the monotony. His cave was empty, boring, and even her flashlight had run dry weeks ago.

More weeks passed and she became desperate. When she was alone in the darkness she saw things, heard things, felt things that weren't there. Only in those brief moments when he came to feed her and breed her she felt sane. Even as she clutched at his chest and pulled him in to her with her own needy hunger. But then he would leave and she would once again be alone with the silent darkness. No longer did he speak to her, there was no need, she knew her duty. She had not heard a voice in what felt like an eternity, even her own she realized. Some where along the line she had forgotten she could speak.

Her belly at this point was swollen to bursting, so heavy she could barely move around but for the shallow water. Inside she could feel squirming, kicking, shifting; it wouldn't be long. Then to her agonized sobs his lust vanished. He didn't even touch her except when he brought her a meal. As violent as his lustful needs were, suddenly they were gone, like an old friend suddenly dead. This more than anything pushed her over the edge. When she lay there in the dark, she fantasized about her children and swollen stomach; in one vivid daydream they burst from her like a ripe melon splitting, and began to devour her in a feeding frenzy. In another she would look in to his eyes and see her end as his large mouth opened, the last moment of that fantasy was his teeth as they paired her body in two. From that dream she found herself with jaw clenched and her arm bleeding across her face--a chunk of her own flesh sliding down her throat.

When the time finally came, there was pain. Heavy contractions wrenched at her womb and warmth rushed out between her thighs. She screamed, the first vocalization she had made in gods knew how long. Somewhere deep inside flesh tore and the squirming grew intense. The first to arrive slithered, wriggling out from her gaping sex and thrashed away in to the water. A second followed, a third, more; she lost count at nine. Through the entirety of her ordeal he never arrived. She was alone as she gave birth, alone as her children swam away, out of the cave, abandoning her just as he had. In abject sorrow she cried, too weak to even sob, just a slow steady leaking of tears and a helpless sniffle.

The last one left her just as the first moments before He arrived. She was hopeful, desperate for his bestial affection. Now however he carried no fish, there was no hungering erection, there was not even a tentative caress of her now flaccid, sagging stomach. Desperate she reached toward him and sobbed, "I love you." He spared her no words in response as his rough hand clasped upon a wrist and he dragged her out in to the deeper water. Confused, she sputtered, "I love you... please..."

He moved in as if to embrace her but he slipped under water. His face pressed to her sagging stomach, the hanging loose flesh drifting aside against his mouth. An instant of clarity pierced her dark insanity. A moment of frenzied terror clawed its way up the back of her spine. The she surrendered to him all over again. Her legs parted as his jaws opened. Before he could close them on her flesh she slid her pelvis between them and pressed her crotch against his tongue, "Yes." She murmured as she felt his jaw close, slowly. He suckled upon her lower body, drawing remnants of her birth out. A splash of blood, amniotic fluid, torn tissue, he swallowed what oozed free. "I will be with you forever." She told him and a crazed smile graced her lips.

With her blood upon his tongue he could hold back no longer. Those vicious teeth sank in to her torso and he swallowed. Her butt was pulled deeper by the suction, her legs folded upward, knees to chest. He opened his jaw again and lunged forward, grasping more of her in his jaw. A breast tore under his teeth, her legs wrenched aside, dislocating as they were forced tight under her arms. He swallowed again and she slid down his throat.

Pain was there, horrific and debilitating, but her hips rolled and rocked, grinding her gaping and oozing cunt against his powerful throat muscles. He gulped again, drawing her deeper until her neck was being pricked by those teeth. She felt strangely vulnerable and excited with her sex and rear so exposed to his powerful throat. He swallowed once again, and this time she felt those muscles contract on her hips and stomach. It was wondrous to feel; a hug so tight and all encompassing that it crushed her pelvis to pieces, shattered her femurs. Her first--and last orgasm ripped through her, a counterpoint to the agony of her dying body.

Again he swallowed and her lower half went numb as her spine broke. Still the echo of that orgasm rolled through her as his mouth closed above her head. She screamed her last breath out in crazed desperation, "I love you!" as his throat collapsed her rib cage. Another swallow and her shoulders collapsed inward. One more and her head was trapped in the tight confines of his throat. Down she slid, gulp after gulp, dragged in to the depth of her mate.

Inane thoughts rolled through her delirious mind as her lower half began to digest. 'I will satisfy him for a long time, such a big meal... he truly loves me doesn't he, wanting to be with me forever?' She smiled happily as she slid in to place. Her broken legs tucked up under her chin, her body bunched up in the tight confines of his stomach. From pores in every surface caustic fluids poured down across her flesh. She lifted her head and opened her mouth and eyes, welcoming him in to her. 'Goodbye my love, I will be part of you soon' she mouthed as darkness crept across her mind.

He lay there, relaxing, his stomach so full he could barely budge. It had been a long time since he had consumed such a great meal. He was satisfied--with the feeling of her still wriggling body growing weaker and weaker inside. He had all but forgotten about his driving instinct to breed, there was a vague recollection, but little more than a passing thought. He would need to find more of these meals in the future. 'Yes' he thought, today was a good day.

Out in the deep ocean a school of a dozen young anthro sharks fed. They had hunted down some great tuna and torn it to shreds. Some day they too would be called to the shallows, in search of what was theres. Every single one of the newborns were male with a deep seated instinct.

Epilogue

One month later the coastguard shot and killed an ancient feral shark man off the southern coast of the island. DNA tests proved he had been the serial rapist and murderer that had terrorized the island a hundred and fifty years prior. The news agencies talked at length about how thankful they were that such a beast was dead and gone. No one linked the missing diver to him; Nor would they link the kidnapping of some twelve women, thirty years later.
