Mario Puzo, The Godfather Even though it sets up a long and unnecessary plotline about Lucy's enormous vagina that will be fixed later by plastic surgery, her and Sonny Corleone's initial tryst at his sister's wedding is, as my wife calls it, a real panty-moistener. That is some good pussy that can spontaneously heal a fella. Following a magesmith named Elof as he wages war against an oncoming eternal winter and the evil gods that want it, he eventually travels to an ancient and corrupt kingdom. They're all wonderfully written smut scenes, but the greatest of the series all happen in the fourth book, arguably the last good one. I also like how these members of the infamous Borgia Family act and think like people with their own wits, sense of loyalty, definition of justice and flaws instead of being demonized into a bunch of 'they are evil! That night, the cat-headed goddess Bast takes him through a marathon hump session that leaves his back covered in cat scratches but erases all his bruises from a beating he'd received by government spooks earlier. Neil Gaiman, American Gods Something for the furries out there He started the book right after the Korean War, and just by coincidence, the implacable, inhuman menace that the brave soldiers of the future have to fight is a horde of collectivist, expansionist insects. It turns out that Heinlein really, really hated communism. As I expected, it was pretty much crap, and not even good smut. While it doesn't end up with a full-on sex scene, the way Fatale describes being touched after being so radically altered by machinery is both sweet and extremely hot. Danielewski, House of Leaves Okay, reading House of Leaves for the sex scenes is like watching Requiem for a Dream to see Jennifer Connelly go ass to ass; it's just wrong. You want some steamy sex in your literature?
