Luna, a liberal teenager with tons of sexual experience, is grateful to Tony, her progressive stepfather, for helping her and her conservative friend Leana access birth control. However, Danny, Leana’s conservative stepfather, discovers that his stepdaughter is being taught how to have sex without any consequences and goes completely mad. In an act of rage, he goes to Tony’s house to confront him for being so liberal, accusing him of corrupting his stepdaughter. Despite the heated start, the two stepdads talk things through, emphasizing the importance of safety, preparation, and understanding over denial. They agree that there’s no better teacher for their stepdaughters than their own loving stepfathers and that the two men can help their stepdaughters out by teaching the girls how safe sex works. And what better way to do it than through a foursome orgy? Swapping is the best way to avoid any weird encounters with their stepdaughters but eventually, the feelings the stepdads have for their own stepdaughters will win them over, resulting in a risky “unswap.”
