I took the book and read the spine, it was a collection of Victorian erotica, another to add to our collection. Sam was straining to reach a bigger book on the top shelf; I put the book down and took her by the waist, lifting her delicate frame higher, her top riding yet higher. She took the book and I lowered her to the ground, yet another collection of erotica. We browsed the shelves, my hand caressing her tiny ass tenderly. Behind us the legs of a chair squeaked on the floor, I turned to see the guy approach us. He was maybe sixty years old, untidy and dressed in clothes that should have been thrown out years before. His baggy trousers shiny with age bulged slightly at the crotch; Sam was turning him on.
