A green light surged from the stone, then it crumbled to dust.
Where scrawny Audrey had been was a massive male warrior, muscles bulging from arms, chest and legs. Where warrior lady Mika had been was a glamorous sorceress, whose unearthly beauty was matched by the waves of magical power coming from her.
Audrey flexed his muscles. Lack of physical strength was the greatest handicap for women warriors. Audrey was more dependent on those potions of giant strength than she would have cared to admit. But this body! It surged with a natural power that was more satisfying than artificial magic. No more periods (the second greatest handicap for women warriors, at least human ones) no more worries about getting pregnant (no. 3) I can work with this.
"Oh no, the rock crumbled. Guess I'm stuck like this."
Mika felt her magical power enhanced through a greater connection to nature and the earth. The change had broken through an internal barrier, enabling the new sorceress to tap greater sources of mana, the energy that fueled magic. And, observing the way Audrey was staring at her new, and very attractive, breasts, she knew that getting the (admittedly, kind of sexy) warrior to do what she wanted was going to be much less of a challenge.
"Yes, it really is too bad. Guess I'm a sorceress from now on."
