It's an "erotic recipe book"!
Honestly, it doesn't seem to be very NSFW, it just has some kinda racy titles for the sections. Just browsing through it, I think I might pick it up. The recipes look pretty good!
Here is the description:
Fifty Shades of Bacon is an erotic cookbook that delves into the full bacon experience. Ok, it is not erotic at all, but it is a tongue in cheek delivery of some great bacon recipes. Everything from basic bacon bits to bacon ice cream to bacon au gratin and alfredo. If you are into bacon, want an interesting conversation piece or are looking for a present for the meat lover in your life, this title is for you. This is a softcover book that has 62 pages and 50 recipes.
