Her mit den kleinen Schweinchen (1984)

At the center of the story are Wolfgang, a fun-loving Bavarian, and his buddy Egon. The two meet again while out jogging in the morning, and soon start talking about their favorite subject: women and sex. When they get onto personal preferences, they conclude that Egon would be better off catching himself a rich older woman rather than a poor younger one. So Wolfgang takes an interest in Eva, who is kind, young, and attractive, while Egon marries Olga, a wealthy widow getting on in years who, by Egon’s yardstick, belongs to the first category. Now he no longer has to worry about money, but jealous Olga keeps a close watch on her younger husband’s activities outside the home. Concerned that his friend is in danger of withering away in the marriage, Wolfgang suggests Egon join him at the “Ball of the Piglets.” Supposedly, lots of pretty young women in masks will be there. Egon falls in love with a girl who seems especially sweet, not realizing until the unmasking the next morning that she is his Olga. Subplots include the story of Freddy, a great sauna enthusiast who one day, completely naked under the bed of the pretty Carry, meets her lover Johnny; and the story of Evi, the maid, who earns extra money by offering sexual favors in her employers’ home and, through her escapades, throws the entire household into turmoil as jealousies arise.
