Miles continued to yell at Molly in his new womanly voice, and his hostile body language indicated to Molly that he was about to get up off the couch and confront her, perhaps even try to hurt her! Molly gulped. Things were not supposed to happen this way. She assumed that the magic that ran through the female side of the family would apply to Miles's changing form, but obviously Miles wasn't quite female enough yet. Molly needed to think of a backup plan, and like yesterday.
Thankfully, she had just such a spell for occasions like this, one that her mother taught her never to use. It was Molly's ace in the hole in case of an emergency, but she didn't want to use it. A part of her said because she wanted a little more time with her son, but in reality it was because the spell required intense focus, as it manually overrided the natural process of how magic worked. It was exhausting, the risk for failure was high, and if Molly's concentration faltered for even a split second, she could completely wipe Miles's personality altogether, leaving him a vegetable(Or worse).
Still, Molly wanted this. She NEEDED a sister. She truly didn't want Miles as a son anymore.
“Confernusi Vincarisius!” Molly yelled dramatically, pointing her finger directly at Miles.
Miles's body suddenly stopped in place as it rapidly melted down into a aggregate of flesh as it took shape into Molly's wishes for a younger sister. As Molly concentrated on exactly what she wanted, the amorphous mass began to be sculpted like clay, directed explicitly by Molly's mental commands.
The process took an agonizingly long ten minutes.
When the ordeal was over, Molly admired her handiwork. It seemed that despite her worries, the witch had succeeded. Miles was gone for good. In her place now stood Mia, her equally witchy goth younger sister.
Mia was dressed in exquisitely gothic clothing and ornamentation, looking simultaneously stunning, exotic, and subtly dangerous. Her silky black hair draped over her shoulders and down her back with a slight wave at the end. Dark eye-shadow, mascara, and electric blue lipstick were applied to her mature but still attractive looking face. Rings covered every finger, including her thumbs, and Molly recognized some of them. The rings were artifacts, made in the old days to hold mystical power for really heavy duty stuff like interdimensional travel and global scale reality warping. Molly was intrigued. She could probably get into a lot of trouble if those were actually the real deal and not forgeries. Molly didn't want to overly sexualize her new sister, but she also had to take notice of her body. Mia obviously took very good care of herself, as her curvy but svelte hourglass body was well demonstrated through the fabric of her cute long sleeved black dress. She even had a pointy black hat sitting right next to her!
The new Miles smiled grimly and said in her new high pitched voice that demanded attention: “Molly, dear sister...”
Option 1: Molly succeeded in her override spell...partially. Miles now has a split personality: One half being his own, and the other half being Mia, a friendly and perky goth who is Molly's sister and partner in witchy stuff. Mia and Miles are constantly struggling for control of their now shared body.
Option 2: Molly's spell went horribly right. Miles's personality has been completely consumed by Mia, a mean, egotistical, sociopath of a younger sister who thinks she can do whatever she wants to others because her powers make her too strong for anybody to stop her.
