The boys that they had been called it a curse! When the witch made her intentions clear, they did not believe her at first until a week later when their body hair began to fall out and they noticed the swelling on their chests.
They returned to the old house, angry and determined to defeat the witch. They would use violence to over power her and force her to unmake the spell.
But the witch defeated them easily and told them that if the outward changes were showing, that meant that the internal work was done. The boys already had uteruses and ovaries sealed up inside them. It was only a matter of time before their “obsolete” parts atrophied and their new cavities opened.
She originally intended to drag the process out for a month, but she decided to be “merciful” and finish it that night. The boy’s cries of pain and terror rose in ptch as their parts fell off and their voices changed.
Because they had shown courage, she gave them a gift, boosting their lust beyond imagination and giving them to each other.
The boys had thought it a curse, but in each other's arms the girls felt only bliss.
