This is a really memorable collection of stories about men who have sisters with a penchant for exposing their nude bodies at just the wrong moment...or the right moment, for us. It includes the story of a brother and sister who trip passing each other to enter the shower, and accidentally fall so that his cock enters her vagina, and another story about a sister who saw her brother's cock sticking out of his shorts, and became hopelessly curious about wanting to see more. Also, the story about a mild-mannered sister who's really into flashing random people on the street, until she accidentally flashes her brother.
