"I'll go first," your girlfriend explains. "I want to see what I look like after I get put under a spell." "Okay, but first you might want to take your clothes off before the spell begins to take effect," You say. "They might get destroyed during your transformation." "Well no time like the present," your girlfriend agrees, and takes off every piece of clothing on her body.
Once your girlfriend was completely naked, you open the book, and look through the pages to see which spell you can use on her. "Okay babe, this book has four categories we can use," You explain. "Myth Transformations, Sex Change Transformations, Body Expansions, and Interest Changes." "Well, let's choose one for each of us, and see if they actually work," your girlfriend explains. "Okay," You agree, and look through both of each category to select a spell to cast on her.
