A man kisses from toes to face a nude girl who pretends to be sleeping. Her hips and waist are covered by something (a linen probably) and her breast is covered by her arm). Thinking she is sleeping the man leaves her.
Laure Marsac is topless with her friend (supposed to be the same age, but played by 24 y.o. actress) when they jump into the pool after being in sauna for a while (where everybody is, according to modern neo-Victorian rules, completely wrapped in towels).
Mia sits beside a man on couch and they keep talking, then kissing and finally he lays her down and after taking her pajama bottom off makes love to her.
Mia hears sounds from her mother's room and slowly opens her door seeing mother and mother's boyfriend making love. For a while she stays there watching them (who are not aware of her presence) and later she leaves slamming the door.
