Sarah sighed, "Well...you see...There's this girl."
Petty stared at the giant girl (At least to her.) "Wow, I never would have pegged you for one of those."
"Wait, what?"
"You know." she grinned. "A Lesbian."
"I didn't mean it like that!" Sarah shouted, hurting the small fairy's ears.
"Geez! Be careful when you do something like that!" Petty yelled, covering her ears. Sarah was about to reply, when she had an idea. Speaking softly, Sarah asked, "So, Do I have to say "I wish" or something like that if I want you to do something?"
"Do I look like a genie?" Petty said flattly, crossing her arms. "No, just tell me, and I'll do it, provided I don't find it completely disgusting."
"Alright, I want you to grow to human size." Sarah said. "It'll make our conversations so much easier." Shrugging, Petty began to speak in some fairy language, and shined a bright light. As soon as the light had come, it had gone, but in its place was a much bigger Petty. Dressed in a green leotard, her body was the definition of femininity. Huge, E-Cup breasts; a waist that made her look as if she were wearing an invisible corset; Long, flowing blonde hair reaching down to her wide hips and bubble butt. Her body was topped off with her fairy wings still on her back, which looked like they could still support her in flight. She had made herself Sarah's height, basing that as normal "human" size.
"Holy crap...I couldn't tell before but...you're beautiful!" Sarah exclaimed.
"Heh, yeah. I get that a lot." Petty giggled in mock vanity.
"Make me look like that?" Sarah asked, about to grab Petty's hand.
"Wait! Don't touch me!" Petty said, and jumped back.
"I'm sorry, What's wrong?" Sarah asked.
"This isn't really my size right now. It's more like...an illusion. If something touches me I'll lose focus and go back to normal. I'm still an amateur, remember?"
"Oh, okay." Sarah said, and paused, and went back to her excitement. "But seriously, make me look like that!"
