The girls of the Derichev family dance in the background of video images where we sometimes see boys in different naturist places. At the end of the scene we find the Derichev girls
The 2 daughters of the Derichev family dance naked at home. Then the eldest climbs naked on a trapeze, the young sister climbs on a vertical bar by spreading her legs, after she straddles the rung of a ladder.
Virginie (Veronique Jannot, 16) takes off her shawl in the rain, her wet white dress becomes transparent, her breasts are visible under the wet fabric. She then dances with Paul(Pierre-François Pistorio, 16) on a bridge.
Lulu's breasts seen in mirror as she changes into a thin gown through which her body is half visible. As she's moving and dancing the gown is raised enough to reveal quick glimpses of front and rear.
