Plot revolves around three couples swapping partners over several consecutive nights. Copious sex dialogue and terms. In a brief scene, one couple has sex, thrusting is heard, and the woman is moaning and screaming. Another couple lays together naked, implying sex. Some action happens under covers, implying brief cunnilingus and handjob. A couple is shown skinny dipping after dark in the backyard pool. Beyond bare-chested men, little nudity is actually seen.
