If you have a lot of time to waste then find something else other than this book to read. Absolute garbage unless you want to spend voyueristic moments reading about incest and double jointed perverts.
When I was young I read, as most young teens did, some things that a mature person would not read, i.e., alleged true accounts of men degrading women through sex in trash magazines such as Hustler, etal. Listen! They were much more sanitized than this pure porn.
