In the heart of a dark, fantastical realm, an ethereal naked pregnant woman with long red hair tied in playful pigtails stood trembling before a colossal Centaur. Its monstrous form towered over her, its cock massive and intimidating. The woman, with big breasts heaving, was torn dress bare. As the Centaur mounted her from behind in doggy style, fear etched on her face, terror bubbled in her eyes. A deep, primal thrust began, filling her with a sensation beyond human comprehension. With each thrust, her body strained, until finally, with a mighty roar, the Centaur's seed erupted, squirting out of her pussy, staining the ground beneath them.
