My former wife, who was in her late twenties, used to love getting about the house completely naked when she knew the guy next door, who was about sixty, could see her. She’d hang clothes on the line in the nude while he spied on her through cracks in the fence. When she’d sun-bake naked, she’d lie with her legs spread for him. I once came home from work early and found her in the backyard reading a book naked. She had a towel on the grass and was lying face down with her butt up and fully spread. I watched from the living room window as our neighbor looked up her butt from a crack in the fence only a few feet behind her. This and more went on for years.
