Carol (2015)

One sex scene between two women. Only kissing is shown (albeit quite passionate), and the scene lasts around two minutes. At the beginning of the scene they both take off their shirts; breasts are visible. No other nudity. The film's score is played over the scene, so not much is heard other than their breathing.

Two women kiss, the scene then cuts to them sleeping with a sheet covering them (sex is implied). Quite brief, and no nudity.
