La Gouvernante (2008)

Regina is a little weird and old-fashioned girl, gets a maid job. It is rather coldly greeted by the inhabitants of the new house. Melissa is the mistress of the house, a preoccupied stewardess who does not disdain connections on the side, including lesbian ones. Horst is the master of the house and, it seems, Regina liked him. It all ends with the fact that the indefatigable Regina will seduce her boss first in the form of a caring nurse, then a lustful schoolgirl and a mysterious stranger. Where can Melissa, with her meager sexual fantasies, compete with her!
