Riven moved through the ruins of Facility Theta, his three great heads surveying the wreckage. His body was monolithic, *powerful*, his golden-black latex rippling like a living storm. Every muscle, every sinew, every inch of him pulsed with the combined might of his former pride, now one with him.
But there was more to claim.
He scented the air—his three sets of nostrils flaring. A heartbeat. Fast. **Human.**
Not yet one of his.
Riven stalked forward, his clawed feet silent despite his colossal weight. The scent led him to a corner of the facility—an untouched control room, dimly lit by flickering screens.
Inside, a lone scientist trembled behind a console. A man. **Young. Lean. Fragile.**
He turned, eyes wide as he saw the *colossus* before him.
Riven smiled—three times.
“Ah,” he rumbled, his voices overlapping, a deep, resonant purr. “A survivor.”
The scientist scrambled back, hitting the console. “S-stay away—”
Riven stepped forward, closing the distance in an instant. His presence was **overwhelming**, his sheer size **monumental.** He crouched, towering over the human, his middle head lowering until his fanged maw was inches from the man’s face.
“I can feel you shaking,” he murmured, his golden eyes gleaming. “Is it **fear**? Or something else?”
The human gulped, his breath ragged. “P-please…”
Riven exhaled a slow, warm breath over him, letting his symbiote’s scent flood the air. Pheromones. **Persuasion.**
He leaned in closer, his lower set of hands gripping the scientist’s shoulders—not crushing, not hurting. Just **holding.**
“You’re trembling,” he mused, his latex-coated fingers **tracing** the man’s chest, feeling his **racing heartbeat.** “But I don’t think you really want me to stop.”
The scientist’s pupils dilated. A deep flush rose to his skin, his body *reacting* before his mind could catch up.
“N-no…” He shuddered. But it wasn’t resistance—it was **surrender.**
Riven purred.
He let his latex flow, just a little—**sly tendrils** slipping from his claws, **coiling** around the man’s wrists, sliding up his arms like warm silk.
The scientist gasped.
His breath hitched.
And then… a soft *moan.*
Riven grinned, his three mouths curling in satisfaction.
“There it is,” he growled, low, husky, intoxicating.
The human’s fingers twitched as the black-gold latex **slid** across his skin, **soaking** into his pores, sinking deeper. He arched against the console, his breathing turning **ragged, needy.**
“I… I feel…” he whispered, voice trembling.
Riven licked his fangs, watching. “You feel **good.**”
The symbiote **rippled** over the man’s chest, caressing him, reshaping him—his frame **bulking**, his muscles **thickening**, golden fur **blooming** over his soft, human skin.
His moan deepened into a **growl.**
His nails blackened into **claws.**
His face twitched, muzzle pushing forward—his lips parting as **fangs** filled his mouth. His breath was **hot**, his body **burning**, his fingers clutching at Riven’s massive form as his humanity **melted** into leonine **perfection.**
The transformation was **slow, indulgent.** Riven **wanted** him to feel every inch of it.
His new **mane** unfurled, thick and golden, framing his now **powerful** face. His thighs bulged, his spine stretched, his tail **uncoiled** behind him.
By the time the change **completed**, the scientist was no longer human.
He was **beautiful.** A powerful, golden-black lion, his new latex-coated muscles **trembling** with pleasure.
His golden eyes fluttered open, his chest heaving. He looked up at Riven—his King. His **Master.**
And then, he **knelt.**
“…thank you,” he whispered, his voice deeper, richer—**leonine.**
Riven cupped his jaw, tilting his face up.
His **newest** worshipper.
His **most perfect** convert.
And soon, there would be **more.**
