The second in a short trilogy of stories: The Triathlon of Transformation.

Each covers one event in the triathlon, set at a different time and place, where the participating guy eventually succumbs to the effects of a transformation.


Mano looked out at the ocean, the aquamarine waters dropping into the sapphire depths surprisingly far from the shoreline. Sinking his toes into the sand, he stretched his naked body, his warm brown skin soaking up the sun's fire. This early in the morning, its bite was quite weak; but the wind was oddly calm, so the world was warming up quite nicely.

The sea seemed to be calling him this morning, beckoning his body to dive in. The other huts seemed oddly quiet; the others might have been out already checking the nets or gathering flax, or perhaps this morning was just for him. In any case, Mano was a strong enough swimmer - the strongest on the island, he reckoned - that he could go off alone. Besides, he wouldn't go too far, and the sea looked like it would be calm for a while.

Roaring, the next wave broke along the beach, scattering out into a hiss as the white foam ran over Mano's toes, his footprints dissolving into generic round dents in the sand. His manhood jutted out over the ocean, still engorged from when he'd woken up. Pulling back on his thick foreskin, he let the salty, moist, warm air roll over his sensitive tip. Mano wasn't shy: not only did he think he was the best swimmer, but had a big, strong body in every respect. Leaning backwards, as though he were going to penetrate the sky with his penis, he stretched, then raced into the ocean.

When the water lapped around his shins, Mano dove forward, his practised body sliding into the water smoothly as his lungs puffed up hastily. His long, black hair clung to his head as he pushed forwards, arms cutting through the salty water, legs kicking powerfully behind him. Tearing through the water, he breathed out, bubbles trailing along his body as he surfaced. Turning his head, he looked back at the island. "Strange," he thought, impressed with the distance he'd been able to cover so quickly.

The calling dragged him further out, strange words flowing through his body like water; Mano barely noticed the light flesh growing between his fingers and toes as he plunged through the water, the gaps slowly filling with rough steely-grey flesh. The ocean's surface cooled, Mano's smooth body sliding through easy as the island slowly shrank behind him. Being in the water today felt a lot like coming home; he moaned sexually, a triangle of grey flesh bursting out of his back.

Lustful thoughts built up in him; it almost felt the water had formed a warm hand, caressing his body all over as something warm, wet and tight wrapped around his shaft. The brown flesh throbbed throbbed, foreskin peeling back from the swollen head of his cock, moaning as the presence calling for his blood seemed to drag him down into the depths. Mano grinned, his lips wide; teeth were splintering in his mouth, jagged spikes remaining in his jaw. Gums blistered in the elongating mouth, extra teeth sprouting in rows behind what he had had before.

Around his body, his brown skin was consumed by blotches of grey. Mano bucked and thrust, writhing in pleasure using his whole body. He felt invisible lips wrapped around his overstretched ones, kissing him and filling his lungs with air. The body he had been so proud of grew, the grooves of his slender, strong muscles disappearing under the more aerodynamic shape struggling to free itself from the human cage that contained it.

A ravenous hunger filled Mano: the basest needs to mate and eat nibbling away at everything else. He wanted - needed - to touch himself, but his arms seemed almost locked in place. His fingers had already disappeared, his arms replaced by long, thick fins. The proud, round nose grew, the handsome Polynesian face extended beyond recognition not just of that of his people, but of a human being entirely.

Mano thrust mindlessly into the water, for that's what his body needed. That was all he could care about: the needs of his body. Flesh grew in between his legs; his ankles had narrowed and joined together, the grey sealing up the gap between them as his flukes flapped near the base of his tail. He felt a new presence, something cold and feral, squirm up beside him. It seemed to be inspecting his new body, tasting the barely-human's life force as the warmth drained it out of him.

Near the limit to what he could withstand, Mano moaned, bubbles of air escaping him. Gills gasped into life, insides wetly sliding around, organs reconfiguring. Bones dissolved, cartilage spreading throughout his new flesh. The deep brown of his eyes gave way to colourless black, the inky colour dripping as if from a flowing pen, as the two orbs stretched to either side.

The coldness seemed very insistent; it split, one heading towards his open mouth to drip in through the tiny gaps in between his open lower jaw, the other creeping in between his buttock to push through his hole before that, too became caught up in the transformation. Spreading throughout his body, Mano embraced the coldness letting it soak through his body without fighting.

Moments before the encroaching flesh encompassed his scrotum, Mano ejaculated. Beads of human semen filled the water beneath his tail, his testicles draining him. As a human, Mano would have wondered how many sons and daughters he could have, his line growing strong. But Mano was no longer a human, and he no longer cared; a moment later, and he was no longer even Mano.

The shark felt the tingling, the long, grey flesh rippling in pleasure as it split; the swollen phallus turning into two thick protuberances. Filled with new seed, the shark hungered to breed; his claspers swollen and ready. The taste of blood on the water called to him, he would need the strength of a full gut to power him.
