A husband offering his wife's pussy! A wife welcoming another man's cock! The pleasure of showing off sex, a circle of people who get excited by the sight of husbands melting in pleasure, this is the "Spouse Swap Club" or "Swapping Club" as it is commonly known. A husband who happily peeks at the semen of another man flowing out of his wife's pussy, and a wife's abnormal sex record that she cannot tell anyone about.
