L'educatrice (2005)

A family with depravity issues hires Helena (Milly D'Abbraccio), a reputed private instructor. Each members will soon find out why she's successful. She takes her job seriously and is very professional but in her own way. She progressively takes charge of everything and keep everyone at her disposal, mostly for sex and when it's time to teach someone's a lesson, it's sex again. Her method is to increase debauchery to make her clients accept the pleasure that comes with it. She seduces everyone but enjoys more the two sons whom she overtly lure to the kitchen for a double penetration or bring one in front of everyone near the pool for a good sex session. Helena can have as much sex as she wants before going to the next family and everyone loves her, she considers her job a success.
