The air was thick with the scent of ozone and slick, rubbery musk as the towering Behemoth loomed over its prey—a lone human male, frozen in shock. Without warning, the creature’s massive cock pulsed, unleashing thick ropes of rubbery goo at blinding speed. The man gasped as the warm, viscous strands splattered across his body, sticking instantly. He clawed at the substance, but it was already spreading, wrapping around his limbs like a second skin.

The goo invaded his mouth, forcing his jaw open as a Behemoth mask slammed onto his face. A long, hollow rubber dildo thrust deep down his throat, muffling his screams into choked moans. The mask fused seamlessly; his hair dissolving as thick latex horns sprouted from his skull. His scalp tingled as the transformation took hold, his humanity melting away.

Then came the violation of his ass—the goo surging inside, stretching him obscenely as it forged a new, elastic hole, ready for use. His human cock was next, engulfed in the thick substance before swelling into a monstrous replica of the Behemoth’s own, throbbing and dripping with pre-cum.

The last remnants of the goo dripped from his form, drying into his new perfect, monstrous shell. He stood now—a Behemoth, just like the one before him.

The older creature growled, a sound that vibrated through the air like thunder, and the newly transformed Behemoth responded in kind. There was no hesitation—no memory of humanity left. Only instinct, hunger, need.

The two identical titans collided, their huge cocks throbbing between them. One gripped the other, lifting him effortlessly, as the other dropped to all fours, his tail flicking eagerly. The dominant Behemoth aligned his monstrous length with the other’s stretched, waiting hole—and with one powerful thrust, buried himself to the hilt.

They moved together, a symphony of slick rubber and primal growls, their bodies slapping in a rhythm as old as time. As their climax hit, they roared together, bodies trembling with release. They collapsed in a tangled heap of shiny rubber, their glowing eyes dimming in the afterglow. Who was the original? Who was the transformed? It didn’t matter. They were the same now.
