Can't Remember the Name

[enlguy]

There's a movie, one of those 70s softcore porns ala "The Pig Keeper's Daughter." I can remember almost the whole plot/film outline, yet can't find it anywhere now, and would love to know the title, or even an actress name if it jogs anyone's memory. It centers on a family. The husband is cheating with a stripper at a club he goes to all the time, the wife is constantly drinking and being shitty to her daughters. There are two teenage daughters. The older one is seeing some guy who gets her a nude modeling gig at one point, where she is ogled by several older guys. There are also scenes of each of the sisters masturbating at home, and I think they talk about it at one point. And then at the end of the movie, the youngest of the sisters has a lesbian scene with a friend of hers. Ringing any bells for anyone?
