Auf die ganz harte Tour (2004)

In this extraordinary erotic film nothing is quite as it seems. A sexy but ruthless property developer (Tyra Misoux) and her scheming lawyer are trying to get their hands on the farm owned by widower Stephan. But no matter how much money they offer him Stephan is not interested in selling his farm. What the prospective buyers don't know is that Stephan's dead wife (Katsumi) has never left the farm. Her ghost is watching over the property and coming to her husband for some supernatural sex. The lawyer tries to blackmail Stephan by hiring a prostitute and taking photos of him with her. But the lawyer is stunned when the photos show himself screwing around with her. So his boss takes matters into her own hands when she tries to seduce Stephan but finds she is riding his ghostly wife's strap-on as well.
