The Cascade was a lewd one, seemingly obsessed with turning humanity into nothing more than sex hungry steer.
It all began with a young lady, aged around 25 or 30. She was a beauty for sure, but her transformation would make quick work of that! She was walking down the street as it happened, blissfully unaware of what was going on. She began to fatten up a fair amount, most of the weight being present in her lower portion and her breasts. She unconsciously began walking on all fours, wiggling her now titanic booty as she moved along. Her neck became longer and thicker as her spine realigned itself. Her face pushed out a bit further as her lips began to puff out, becoming donut-like. Her clothing vanished entirely until her clean, creamy, silky skin was made bare for all to see. Her extremities exposed to the elements, they began to turn aroused on their own.
Soon, the more extreme changes began to take place. Her vagina began to moisten furiously as her clitoris was replaced with a fully functioning penis and testicles. The bones in her arms and legs reshaped to resemble those of a horse's as her hands and feet turned into fleshy, hoof-like paws. Her butt swelled up enormously, as her anus puffed up into a puckered donut shape of its own. Her boobs swell large enough to lightly brush the ground with her nipples, and her testicles swell to the size of watermelons. Her now erect cock grew in length and girth as well, becoming two feet in length from base to head.
Thoughts soon began to enter her mind. She was filled to bursting with the desire to fuck something that looked like her. She wanted to suck the semen out of a giant cock, she wanted to stuff her own cock in someone's pussy or asshole, and she wanted a cock in either her own pussy or her own asshole! Her tongue lolled out as a dopey grin formed on her puffed out lips. She began to pant and sweat and moan as her libido began to infinitely rise. It wouldn't take long for her to fulfill her desires either, because soon all of humanity was going to become very like minded.
