"You are going to be changed into an animal surrogate."
"A what?" Jon gasped.
"Its a term we use for people that give birth to animal babies," said the nurse. "You'll be changed into a fully functional female, with breasts, uterus and other relavent physical features. There will be one major difference. Your uterus will be designed to carry animal fetuses in addition to human babies. Its a program we do with the government, working off your punishment by helping the environment. Zoos have frequently had problems breeding animals, particularly rare ones, and this is designed to increase birth rates of endangered animals. Punishees are impregnated with the fetuses of endangered animals, carry them to term and give birth to them. And don't worry, your body will be able to handle watever type of animal you are pregnant with, with no more discomfort than you would experience with a human baby. Your breasts will produce milk that you can use to feed your babies. Your maternal instincts would extend to your animal 'children,' allowing you to love them and want to continue having more."
Jon thought about it. It was for a good cause and he could end the wish whenever he wanted. He decided to continue on for a while, to see what it would be like. As he fell asleep that night, he hoped that they would not get him pregnant with an elephant. Able to handle it or not, that would hurt.
