The Plot.Cindy, a sweet-young-thing being raised in the suburbs with her half-sister Donna, is shyly undergoing a sexual awakening. Fifteen-year-old Cindy and 17-year-old Donna share the same mother, but have different fathers. After she espies Donna making the beast with two backs with her Dad, Cindy goes wild. She shucks off her inhibitions, smokes pot with her friend Karen, and the two gratify their Sapphic desires in each others arms. Meanwhile, Donna, more advanced along the path of sexual awakening, achieves congress with three young swains. Cindy is seduced by Donna's beau, but Donna discovers them as they are about to bump bellies. Her boyfriend throws Donna out of the house, and tragedy ensues when a crying Donna, distraught in the street, is run down by a passing motorist. Cindy must live the rest of her life with the knowledge that her pursuit of carnal knowledge led to the death of her sister.Let's be honest, you ain't watching this for the plot. You're watching it for the hot chicks and in that, this movie delivers in spades. There are some rocking flat stomach bodies that you just don't see these days. And lots of voyeuristic shots with legs for days that are gone from movies of today.This film was made when women were objects and men were happier for it. Alice Friedland, who is uncredited as a stripper has the most amazing body that you will ever see.Nary 10 minutes goes by when there's another hot naked chick on the screen. Va Va Voom. Not sure, however why this film was rated X. There is no hardcore sex nor do you see men;s junk.

The reviews stating that this film is void of plot, acting, and merit are, for the most part, right on target. Cindy and Donna is nothing more than a soft-core exercise so prevalent in the 70s with a pseudo-story about two half-sisters sexually awakening - certainly peaking at different times as Donna is having a relationship - witnessed by Cindy - with Cindy's father(I think?). The material is spartan when it comes to plot development and really is just one sleazy scenario after another. There is essentially no acting in the movie except a rather mediocre performance coming from Susy Allen as the harried, booze-filled mother. Her performance was at least interesting if not definitely over-the-top. There is some weird moral the director and scriptwriter try to squeeze into all their soft-core nudity scenes, near-incest scenes, and masturbation scenes, but I wasn't buying. This film above all was a lesson in tedium and how one must sometimes endure even the most trying of films to get through to the end. Cindy and Donna is one of those films.

A teenage virgin, Cindy, is curious about SEX. She watches her older half-sister Donna have SEX with her boyfriend in his car, and then she has SEX with herself afterwards. Meanwhile her father is busy having a lot of SEX with a nubile stripper/prostitute, which doesn't stop him from staggering home in a drunken stupor and having SEX with Donna (his own step-daughter)while Cindy spies on them. Cindy responds to this by going to the beach with her more experienced best friend where they pick up two boys. Her friend has SEX with one of the boys, while Cindy almost has SEX with the other. Later they return back to her house (her parents have gone away to Vegas) where they smoke a joint and end up having lesbian SEX with each other. Meanwhile, sister Donna poses for nude photographs for her boyfriend's friends and has SEX with all three of them. And then finally Cindy at long last has SEX with a guy.You get the idea that this movie has a lot of sex in it. In fact, it kind of suffers the "curse of too much sex", a problem afflicting almost all hardcore sex films and many softcore films like this: There is so much sex in this movie that it pretty much crowds out anything else of interest (i.e. plot, character development, basic production values). So unless you are a young, heterosexual male who is planning to spend 90 some minutes masturbating, I really can't recommend this. It does have some sicko 70's elements (for instance, the quasi-incest), which will probably offend the sensibilities of some, but for me there is not nearly enough of this since it at least makes the movie less boring. There is also some attempted "comedy relief" by the two drunken parents, but they are mostly just annoying.The only possible saving grace of this movie is that the four actresses who play the young people (the two sisters, the friend, and the father's mistress) are all very attractive, which isn't always a given in 70's films (70's porn actresses were often pimply and corpulent and generally looked like they'd been picked up in a Times Square vice dragnet). The four girls are obviously all somewhat older than the "teenage" characters they play, but they all have a nubile girl-next-door freshness without the freakishly huge breasts or the unnatural Russ Meyeresque proportions (not to metion the silicone Frankenstein look so common in these kind of movies today). This is still no reason for anybody but a hairy-palmed sex fiend to watch this movie, of course, but it should make it a little more fun at least for those who fall into that category.

Cindy is a very curious girl. Her big sister Donna can get all the men she desires, in fact she has a new one every night of the week. Even her good ol' dad is having an affair with a stripper he met at a bar. (Looking at his screechy shrew of a wife, I'm not surprised..) Why can't she get that kind of passion in her life? So follows two hours of tedious 'coming of age' drama which basically is film-speak for "lets convince our young starlets to deprive themselves of their tops every two minutes".I have to admit I was shocked not to discover Russ Meyer's name among the credits. Mind you, the women in this movie are probably not quite busty enough for him, and there's no sign of the underlying humour here that you see in his best work. Yep, this is serious stuff all the way, and all the softcore sex, lesbian, massage and shower scenes seem to be building up towards making a firm point about the futility of a hedonistic lifestyle. Personally I'm not buying it for a minute.. this is a skin flick with a moralistic ending thrown in an afterthought just to satisfy the censors so it could get a mainstream release. In the matter of whether you should watch it or not, I would say: If you want mild porn, go to one of the many specialist shops that cater to your particular needs. If you want a quality movie about growing up, I would suggest The Breakfast Club or Flirting. Under no accounts should you sit through this nonsense. Unless you want to be put off sex for life.. 0/10
