Somebody is going to have some fun with this, muttered Dr. Erlanger on beholding Ashley's cloned penis. Minotaurs tended to be well endowed, and this one was not going to be an exception.
The addition of the external genitalia, the final stage in Ashley's transformation, took place in two stages. First, the penis was carefully grafted into place, with the proper connections to Ashley's urinary and genital systems, as well as to the blood vessels that would make it capable of erection and the nerves that would provide it with sensitivity. Then, in a trick over five hundred years old, Ashley's remaining labia was formed into a scrotum, and his testicles coaxed down from his abdomen to their new home. At the end of the process, everyone hoped, Ashley would be as capable of functioning sexually as a male, and even of fathering children with a female minotaur, as if he had been born with a male body.
The success of the procedure was demonstrated when the still-unconscious Ashley urinated through his new penis. Everyone cheered, then fell silent as the penis grew larger, and larger, and finally stood out stiffly from Ashley's body. Dr. Erlanger knew that this was in all likelihood simply a reaction to the extra dose of testosterone coursing through Ashley's veins, but couldn't resist smiling. "Well, looks like someone's having pleasant dreams" she remarked.
Day Seven was anticlimactic, just a long series of tests and measurements to make sure that all the grafts had taken properly and the nervous and other systems were functioning within designated parameters. Every indication was that the patient on the table was a healthy young adult male minotaur with some more growing to do.
Dr. Erlanger got to the lab bright and early on the morning of day eight. All the tests could check out, but until you woke the patient out of his induced coma, you never knew.
Ashley woke up.
