Die Andere (1986)

An engineer named Walter is sent to Brazil to work on the construction of a large dam. During the project he goes back to visit Germany, and feelings well up in him when he sees his wife. Before he goes back to Brazil, he asks his wife to accompany him for the remainder of the project. She says no, and admits to having an affair in his absence. Walter is thrown for such a loop that he winds up killing his wife, and leaves no trace of the body. While wondering about how he will explain her being missing, he remembers that he knows a woman who looks strikingly similar to his wife, and pays her to play his wife and go to Brazil with him.

Magdalena Ritter has the dual role in Die Andere (1986) of playing the wife, Astrid, and the double, Marion. She provides a healthy dose of both T&A while undressing, in the bathtub, and while banging in bed. Talk about doubling our pleasure!
