"My beautiful mother" is a classic Victorian erotic novel, published in '900s. It contains graphic sexual descriptions and themes.
Whilst I was staying at an out of the way village on the Sussex coast, I used to take long solitary walks, and several times saw a very beautiful girl sitting on a secluded part of the downs, attentively reading what looked like a manuscript in a black cover. One day, on the same foot-path, I picked up what I believed to be her manuscript book, and looking curiously at the contents, was surprised to find it was a tale of the grossest kind. I sat down on the bank to enjoy this unexpected voluptuous treat, when suddenly I was startled by a breathless exclamation of: "That's my book! Oh, give it me back, Sir; I must have dropped it as I passed along here, a short time ago, and ran back to find it."
