Erika Müller lives with her precocious daughters Tanja, Micha, Anna, and Gloria in a small detached house. The shapely, pierced Tanja spends most of her time at her secretarial job in the shipping company's office with her legs spread wide beneath her father. The busty blonde Anna has sex with her brother Peter in broad daylight, and Micha, the youngest, sleeps with a different guy every day. While father Bernd, completely drunk, flirts with the buxom barmaid at his local pub, and daughter Gloria meets up with her friend Lisa for a gangbang, mom Erika, the big-breasted vixen, gets a good pounding at home from neighbor.
