The Servant (2010)

A man and a woman passionately kiss while she is on his lap.

A man and a woman has sex in doggy-style. They are fully nude and he is thrusting her from behind hard. Then she is riding on top of him and moaning and screaming from pleasure until she climaxes.

Another scene where a woman and a man have sex, both nude, breasts clearly visible, several positions

Do not trust the PG-13 rating. It is not a family film.
