Hot Summer in the City (1976)

This has explicit hardcore sex scenes showing penetration and fellatio.

There is some violence in this movie. Several characters have guns.

There is plenty of swearing in this movie, as well as disrespectful language towards women.

There is a lot of drinking in this movie, mainly whiskey.

Some may find the rape scenes intense, however they're not done in a particularly violent manner. It's more in the context of being an excuse for sex scenes in what is basically a low-budget porn movie.
