Becky followed Ellen upstairs after they loaded their arms with plates of pizza and cans of assorted soda brands. "Laura!" Ellen called out as they reached what was apparently the correct door. Laura opened the door moments later.
Apparently they've done this quite a bit, Becky mused.
Becky dropped everything she was carrying, thankfully only soda, as she spotted something she truly hoped she'd never see again. A sticky note on one of Ellen's posters. She walked mechanically over to it and some distant part of her mind noticed Ellen and Laura following her, though she knew even if she told them not to look it was too late. They read in unison, "I wish I was five years older."
Becky felt quite different all of a sudden. Her clothes were very tight, especially on her chest. She looked down to see breasts just barely contained by the thirteen-year-olds' clothes that didn't change with her, though they still looked about to burst, and a wholly feminine figure besides, though a bit thin. Ellen and Laura were in the same situation, and they both seemed to be moments away from screaming, though whether in joy, shock or pain, Becky didn't know. "This is exactly how I got turned into a girl..." she mumbled, ripping the sticky note up into tiny pieces and throwing them out the window like horrible yellow confetti.
"Really? A sticky note?" Laura asked, glaring at her. "So you knew about this?"
"No, of course not. I didn't want to be turned into a girl, and I wanted to take my time getting this old, thank you very much!" Becky yelled, and only the closed door kept them from being heard and discovered.
"Calm down! We can borrow some of my big sister's clothes for now and explain this to our families. I don't think Becky did it, but maybe we can find out who did," Ellen said, surprisingly calmly. "So... who goes, Laura? Becky doesn't know where her room is."
