Her cocks moved in a circle as her body stopped at the back of the zoo, they then arched, lifting her hind quarters and exposing her equine pussy. She heard a cacophony sounds and large booms as the animals escaped from their cages. In horror she bent down and braced herself against her cocks, still wriggling and cumming.
She then heard the stampede as hundreds of animals of all shapes and sizes rushed for her pussy. She screamed as elephants, rhinos, deer, lions, tigers, bears, cheetahs, boars, and many other land animals crawled into her pussy, she screamed as birds came down and rushed in. She was a blimp now and they were still coming. It seemed like hours until it stopped. Then all of the animals were absorbed into her pussy.
She waited with fear, then the changes began, she felt something at the base of her neck she twisted her neck to see to her horror a giraffe's head and neck shooting out on both sides, her arms had started to grow feathers, they got longer and she grew more arms, fifty of them, all of them from apes and monkeys. Her cocks tensed and she screamed as she grew three more, making a total of six. She grew extra legs from all of the horses and zebras, resembling a massive centipede now. She grew two more elephant trunks as her balls expanded even further, all of the legs she could grow wouldn't help her move now, she was at the mercy of her snake like cocks. The changes continued for hours until she resembled a genetic experiment gone wrong.
Her cocks then started to move an cum, the giraffes trapped in this new foreign body tried to escape, moving legs and arms they weren't familiar with forcing Jen to scream in horror as they rubbed against breasts, udders and other parts she didn't even know the name's of, her cocks then decided their next destination and started to move forward. She could only try and fight them and the giraffes as well, it was no use, she was now a true monster, and her cocks wanted to be satisfied.
