New Family Rule

Step-siblings, Eddie and Sara, come home from their classes only to find their stepfather, Gordon, and stepmother, Alice, in the buff. The parents explain they have turned into naturists and invite the siblings to immerse themselves in this lifestyle. Eddie and Sara reject the idea vehemently.
Scarcely expecting their parents' persisting nudist ways, the siblings promise to stick by each other, cherishing the unwavering trust they have. Some days later, finding their folks still committed to nudity, the siblings forfeit hope of reasoning with them. Resolved in their bond, they vow to stand together.
The scene takes a racy turn when Eddie walks in on Gordon, Alice, and Sara all in the nude, engaging in playful activities. Distressed and feeling deserted, Eddie retreats to his room only to find Sara attempting to sway him to unite with the family. Sara hints this newfound lifestyle involves all activities - even sexual ones.
Gordon and Alice reinforce Sara's call, pressuring Eddie to conform, exalting the pleasures of coexisting and indulging in intimate acts in the nude as a family unit.
