The book, “642 Things to Write About” has writing prompts to get those creative juices flowing such as:
Write a sex scene you wouldn’t show your mom. Describe a time when you wanted to orgasm but couldn’t. Write an X-rated Disney scenario. Write a scene that begins: ‘It was the first time I killed a man.’ You are a serial killer. What TV shows are on your DVR list? Why?
Apparently the book was part of a college level writing course that was being taught at the high school.
I dunno if giving students a workbook which has sexual content qualifies as "child pornography", but those do seem rather inappropriate. Unless you want your kid to start their porn writing career off early and right. Or to imagine themselves as a serial killer.
ETA: If this is the incorrect circle, please let me know. I wasn't sure where this fit in.
