"First, I wish Jon was a girl, and joined the cheer squad at the start of this year," Sarah began.
"What? Sarah, how cou-"Jon started, stopping suddenly as she heard her new, girlish voice. She'd become a female counterpart of her former self without even realizing it happened. No doubt she also had a cheerleading uniform somewhere.
"Hm, that's strange, but ok. I wish Jon's hair was longer," she said as Jon's hair grew out a couple inches. Apparently a gender change on its own didn't make a person's hair any longer or shorter. "Next, I wish that Jon, no sorry, Jane won't be able to touch the stone, tell anyone about it, or tell Karyn I have it," she continued, trying her best not to leave any loopholes. "Also, I wish Jane knows everything she needs to be a good cheerleader, and looks up to me as a role model,"
"Ok Sarah, you win. I'll do whatever you ask, just please don't make any more wishes, I beg you!" Jane pleaded, blushing and cradling her new breasts.
Suddenly Sarah had an idea, "I wish Jane would spend the next two minutes masturbating, and no matter how much she cries and screams, nobody besides she and I will pay any attention,"

She wasn't aroused by this; it was just her way of establishing dominance, and introducing the girl to her new anatomy. Jane looked away, crying and sobbing uncontrollably the whole time, tears running down her face. She'd never felt so weak and powerless before, and the worst part was as she felt herself orgasm, she started giving involuntary gasps of pleasure. Once it was over, she put her pants back on, struggling to catch her breath. "Sarah, tell me what did I do to deserve that?" she asked, trying to keep her tone level. "What could I have possibly done to you that was so horrible, I deserved something like that?" she snarled, suddenly angry.
"Oh that? I was just helping you get used to your new body," Sarah answered casually, almost cheerfully. "and now, time to have a bit of fun with Karyn "
