Lulu (2005)

Leon Mortier, a wealthy publisher, falls for the mysterious Lulu (Vlatka Simac) after offering her a ride and takes her and a man he accidentally hit with his car into his home. Obsessed with suspicions of infidelity between the girl and her friends, he organizes a dinner party to confront them and cut them out of his life. His plan to get rid of Lulu as well, conceived after discovering her in his son’s arms, ends up backfiring on him in a completely unexpected way.
At the 20-minute mark, Vlatka Simac is lying naked on the bed, holding a knife in one hand. A man approaches and lies down next to her. The two roll around a bit on the bed. At the forty-first minute, the naked actress admires herself and moves seductively in front of a mirror, then covers up with a red sheet. At the forty-eighth minute, Vlatka Simac naked is sitting on a stool in a painter’s studio. When he arrives, she stands up and hugs him. The two caress each other, then lie down on the floor to have sex, while Adelheid Roosen spies on them and touches herself between her legs. At the 63-minute mark, Vlatka is having sex in bed with a man, but the arrival of another man interrupts them. She gets up and runs to a corner of the room to get dressed.
