Four couples. Frustrated wives plot to swap husbands and try SEX. Neighbouring couples, a newlywed couple and a matchmaker couple exchange partners! In front of the husband, someone else's penis is thrust into the mouth and vagina, causing intense excitement. Watching their own husband having sex with another's wife, the couples are greatly excited by the sight of adultery NTR. Embarrassment, guilt, and pleasure are two sides of the same coin!
