Heidi: Das Luder von der Alm 3 (2005)

Heidi, her body is the definition of sin. Mother Nature did her best to create a body and mind that knows just one rule and follows just one aim - pure, unadulterated, neverending lust. In the third installment of the series, Heidi has an extended and outrageous threesome in the Swiss Alps. Her first two suitors get chased away but they hide behind a rock to watch the other man have his way with Heidi before they eventually come back and come again. It is nothing but lust and loins high up in the Swiss countryside.
