Bosom Destiny: Growing Concern
Elizabeth is back in her quest to fulfill the requirements of her Great Aunt's will and inherit her fortune. Her breasts continue to grow despite her best efforts to control and mitigate their size. She is trying to understand the rules and quirks of her role as an unlikely defender as she is thrust into strange places and situations and conflicts with people she doesn't know and will never see again.
She uses her ability to pass her growth and excess on to others as a way to keep her size from becoming too large for her to handle, but in the meantime her personal and family relationships suffer.
