Pregnant

In these stories, a main character gets pregnant — either by choice, accident, or otherwise. She may be a breeder, who’s sole purpose is to be a physical vessel in which to bring new life into the world. Or maybe a guy was transformed into a girl, had careless unprotected sex, and now is going to be a mom.

Whatever the reason, whatever the cause, part of this person’s transformation leads to their inevitable impregnation.
