Four married women think, "If we swap husbands, we'll be able to enjoy fresh sex." One of the wife's friends and acquaintances seduces her husband. The husband is rock hard and ready to go, and they kiss and touch each other, while the wife and the other husband watch from behind the scenes and get excited. The swapped couples watch and are watched by each other in sex, with the husband's dick in their mouths and another man's dick in their pussies. The wife gets excited watching the other woman's pussy go in and out of her husband's dick.
