You grabbed a book in the box randomly and saw the title "What the other side is like." then you quickly spotted some text near the bottom that was small which read "do not read if over 12 years old." Your eyebrow raised out of curiosity. Was it a gross out book that said it wasn't for people over a certain age for a certain "edginess" factor?
opening the thing book you saw a page with a boy and a girl that read "boys and girls are different, and these differences are not bad. Let me show you what being a-" after the word what there was a shimmering spot which started to show the word "girl" followed up with " is like." You wondered if you saw something and decided to turn the page, and saw the picture of an anatomically correct child girl.
"What the fuck?" you said out loud as you read the words "girls don't have a dick like guys do, they just have a little hole that they pee with. Why not feel what it's like to pee with one, don't forget to wipe." You then felt like you needed to go take a piss and rushed to the bathroom. After you pulled down your pants you noticed that instead of your dick you had a vagina now. "Shit." you quickly said as you realized some of the junk was magical. You then sat yourself on the toilet and went to the bathroom. You had the book with you and decided to read through the rest of it to be safe, and you could probably read it again to become a guy again.

When you got to the last page you read "Now that you are a girl go out and see how it feels to be a girl where you are." You were a little confused, the book was below your chest and yet it was still flat which a small pat confirmed. Then you looked around and noticed that everything looked bigger and you figured out that you were now a little girl. You closed the book and opened it where the words "Go be a girl for now." showed on every page.
You got on your phone and called Marcy, and Marcy said "Hey there Stan what's up?"
You asked in your girly high pitched voice "Could you come over?"
confused marcy asked "Are you Stan's cousin or something?"
to get her to come over faster you said "Yes, Stan's getting something ready and told me to ask you to come over to his house."
Marcy said "Gotcha Miss, i'll be over quickly." In a few minutes Marcy was over and you let her in and Marcy saw you in your giant shirt which was more of a dress on you, and the box of junk was on there.
You said "Marcy, why don't you take a look at some of the stuff from the garage sale? Stan will be back from his room soon."
Marcy nodded and then walked to the box and took out...
