Settlers (2021)
Violent post-apocalyptic sci-fi setting. A girl's father is killed by a guy. The guy settles in her family house. Her mother, albeit obliged by necessity and actually looking for revenge, establishes a very ambiguous relationship with the guy, gets touched and has sex while the daughter notices it.
The scenes are few and not so explicit, but the feeling is pretty tense and I think it's perfectly in topic.
