Four couples. Frustrated wives plan to swap husbands and have sex. A couple from the neighborhood, a newlywed couple, and a matchmaker couple swap spouses! They get so excited when another man's dick is thrust into their mouth and pussy right in front of their husbands. Couples get so excited when they see their husbands having sex with other people's wives that they are caught being watched and are caught having an affair right in front of their eyes. Shame, guilt, and pleasure are two sides of the same coin!
