Dustine took in her appearance in the mirror as she walked past. The 20-foot unicorn struck a pose, raising two of her four arms into the air and flexing, letting her other two arms cup a pair of her six, huge breasts. She bared her teeth, letting her 10-foot, slimy, black tongue run over the sharp edges of her fangs. She smiled. It was strange to have fangs as a unicorn, but she liked the fact that she was a little more demonic than the pure ones of legend. Sure, she had the snowy white fur, and the pastel-colored streaks and horn, but her huge body, her fangs and double dicks and tongue? They weren't what people generally associated with the myth of the pure-hearted creature.
But that served her just fine, she realized as she waded into the bath. She didn't care what people said. She was a beast and a monster. A sexy one. And little Krissi loved her for it and loved being claimed by her strong, sexy body. And Dustine knew she'd be able to improve it for their next fuck.
The anthro unicorn knelt in the pool of her own, golden milk, and dipped her two cocks in it until they were fully submerged. She could already feel the milk enhancing them, but she wanted more. Her horn flashed, and her cocks began to drink up the milk.
They sucked it all - every gallon of it - into her huge balls, stretching them uncomfortably to their limits. The two car-sized wobbled as they easily stood 12 feet tall. Then, they began to spasm.
Dustine keeled over as her balls began to pulse and churn. Her cocks wobbled, before surging with growth. Ten feet to twelve, to fourteen, longer and larger they grew. They bloated with thick muscle, just as the rest of her, and veins thick enough for a human to slide through wrapped around the shafts. Sixteen, eighteen, twenty, twenty-two feet of hot horse cock rose above Dustine's head, dwarfing the giant's body. They writhed like snakes, and suddenly Dustine was able to flex them and move them just like the tentacle she called her tongue. But her balls were not done yet with their enhancements
Her sack thickened and became indestructible, impervious to anything. Two more testicles dropped down into it. Her sperm grew wild and strong, seeking out eggs and destroying any that they deemed too unfavorable for her offspring. And then, the milk enhanced her hormones.
Superpowered testosterone flooded through her veins. Her furry coat thickened into a wild, plush thing deep enough that one could lose their whole arm into it. Sweat ran through it, setting off a smell that was sour and musky, but so alluring it was impossible to ignore. Her armpits and groin were the worst, becoming thickets that excreted pheromones that just made people want to submit to her, completely wiping any other thoughts from their minds.
Dustine's body creaked and groaned as she began to grow larger. Her hooves dug into the floor as she arched her back, feeling power flood into her. Muscles piled onto her frame as she stretched taller and wider. The 30-foot Amazon ground her teeth as they grew sharper, and her form more intimidating. Her jawline sharpened and clouds of hot steam and pheromones huffed from her nostrils. An Adam's apple appeared in her throat. Drawing herself to her full 35-foot height, she threw her head back and roared the way no unicorn had done before. It was a deep, primal sound that shook the house and sent animals scurrying away from this truly monstrous creature.
Her wide stance held her firm as her hooves sharpened and her tail lashed behind her. Her mind had become even more aggressive and dominant. The world would bow to her will. And Krissi, oh Krissi would be her perfect little sex doll, constantly filled with her cum. She'd take good care of her, but all she wanted to see was her tiny, human daughter utterly submit to her whims.
Dustine's hands came to rest on her two, 22-foot cocks. First, she'd finish what she came here to do.
