Voir la mer (2011)

Young brothers Nicolas and Clément leave Montbard to drive to Saint-Jean-de-Luz to visit their mother, taking advantage of the trip to explore France. Along the way, they meet Prudence (Pauline Lefèvre), a girl without a family who decides to join them. Both fall in love with her, and the three enjoy a carefree summer in a fragile balance that is destined to crack upon their arrival at their destination.
At the 42nd minute, Pauline Lefèvre bathes in a pond wearing only her panties and bra, while two guys sitting on the shore watch her with fascination. Shortly afterwards, the actress walks towards a secluded spot in the woods. A guy joins her and has sex with her on the grass. At the fifty-third minute, in an alternating montage scene, we see Pauline Lefèvre naked having sex in a camper van, then in bed, then in the shower and finally in her panties and bra sitting in a laundromat.
