In a boarding school for girls in East Switzerland, young daughters from a better family (including Julchen and Jettchen) learn the tools for life by day and transform themselves into little sluts at night who hop from bed to bed and from room to room and, as far as the teaching staff is concerned, ahead of none shy away from crime. A Mrs. Wagner lives in Zurich, whose erotic appetite is enormous and whose husband, who is connected to bodybuilding, works on his muscles all day long, so that in the evening he sinks exhausted into bed next to his attractive wife. Ms. Wagner suffers from sexual hunger and tries in different ways to get enough. Julchen and Jettchen come to Zurich to help out in their uncle's pharmacy and meet Mrs. Wagner there, who finally wants to get her husband to do his nightly duties with chemistry. Julchen and Jettchen listen to Frau Wagner's problems and suggest that they be brought into their house as nieces, in order to remind their muscular handsome boy of his manly duties in natural, humane ways. And so it happens that Mr. Wagner finds two beautiful naked nymphs in his bed in the evening, who make him such unique offers that he cannot object and he has so much to give that night that his wife finally gets her rights again .
