Der Unfisch (1997)

Der Unfisch (1997) is an Austrian fantasy film about a woman named Sophie (Maria Schrader) who inherits a giant taxidermied whale when her uncle passes away. The whale is parked in the center of town and is fully furnished inside, causing Sophie to take up residence inside it. When the townsfolk discover that anyone who sleeps with Sophie inside the whale's belly will get granted one wish, it isn't long before the whale turns into a brothel, with every guy in town lining up to sleep with her. Maria Schrader gets naked multiple times throughout the course of the film, as you can see from the screen cap below. There's some nice looks at her lactoids as she lays beneath a dude who's banging her, and there's even some full frontal action as she walks fully nude through the whale's belly and later reclines on a couch in the buff. After seeing all of Maria Schrader, it's no wonder so many guys laid her!
