Eric Newberry marries into a nudist, incestuous family. During his first summer vacation at the Garden of Eden nudist camp his mother in law seduces him which leads him into the family's libidinous frolics. Though becoming involved in the family's sexual escapades Eric refuses to allow his children to be folded into the family fun. In chapter 3 his son and daughter are secretly "initiated" by their grandparents.
Lucien purchases a flute in a pawn shop, and immediately begins playing it. There's more to the flute and Lucien, than meets the eye. He's special, and so is his flute music.
Thanks to a strange birthday gift from his, apparently, half-beautician/half-mad scientist mother, all the girls that share Lucas's hot tub are acting more and more affectionate.
