Beau-père (1981)
Rémi is a struggling pianist whose wife, Martine, is killed in a car crash.
His 14 year old step-daughter Marion expresses her desire to stay with Rémi in their apartment, where she tells Rémi she is physically attracted to him.
While he initially resists her advances because of her young age, he eventually gives in to their mutual desires.
It was Ariel Besse’s first film role, and she was only 15 at the time. Although she is nude in the film, her parents gave approval, saying she was treated sensitively.
