Need help IDing a bunch of movies

Longtime lurker, but relatively new member, and would like some help IDing some movies that I've seen clips from over the years, and I will try to be as accurate and close to memory in the descriptions as possible.

1. Much older movie, probably from the 60s or 70s though I saw it on tv in the 90s. Scene takes place in a barn or something similar, a group of soldiers are attacking a woman, we see them rip open her blouse. Her friend/sister/whoever tries to come to her rescue but the soldiers grab her as well, there's even a tight shot of them raising her skirt and trying to pull down her underwear. Their commander enters and dismisses them, and while the two women give the officer an earful about the soldiers attempting to rape them, he assured them that if they try it again he would punish them. And it's not "Outlaw Josey Wales" as someone else I asked thought.

2. Clip used to be on Dailymotion, but they recently cleaned out all their sex videos. A lady author is at a booksigning and has a daydream about being approached by a handsome man who asks if she'd have dinner with him, telling her to just be honest and not think about the answer. They then go into the back of the bookstore, strip down, and have sex until she's snapped back to reality.

3. Another clip that used to me on Dailymotion but no longer. This one was a movie involving a relationship between a high school boy and an older woman - there was a number of sex scenes between the two, including one that takes place when the woman shows up in the boy's room after he showered and she rides him while sitting down, after that she tells him to leave for fear his father would catch them. Another scene she gets mad at him for a failing grade in French on his report card, so she gives him an impromptu lesson by spanking him and saying in French that she's hungry and wants something hard.

4. Yet another Dailymotion clip. This one was an incest scene where a guy sneaks into a room where his sister and her boyfriend are making out and actually wants to get in ont he action, so the girl has both of them lie on the couch while she strips down to her underwear and starts seducing her boyfriend while her brother watches. This may or may not have been a foreign film, but the dialogue was not in english and it sounded dubbed.

5. Yet another Dailymotion clip, and another incest scene. This one features a slightly older brother and sister (maybe 30s or 40s). They're in a shack of some kind and the brother starts attacking his sister, so the sister tries to fight back by grabbing his crotch, which turns both of them on. They make out for a little while (spittle included) and finally they drop to the floor and the brother has sex with the sister.

6. Yet another Dailymotion clip. This one's a rape scene. It takes place in an office at night and a male worker is yelling at a female coworker, I don't remember what about, but it seemed like his sister was raped by a man his female coworker was involved with, so he decides to take revenge out on his female coworker and rape her to see how she likes it. He seemed to really enjoy it too, he was licking her face and everything.

7. Lastly, this one's a Youtube clip I found by accident countless years ago and haven't found it again since. I think this one may have been sci-fi/supernatural, or maybe even a parody, I don't know. There's a dim, green-lit room with a hole in the wall where we see an eyeball spying on a young couple having sex in a bedroom. A girl is riding a guy like crazy and the scene kept cutting back and forth between them having sex, and the voyeur spying through the wall where his eye keeps shaking. The girl even whips out a video camera at one points and tapes their intercourse. There's then a splatter on the wall in the green-lit room (supposedly cum from the voyeur masterbating), and the couple are then interrupted by two or three guys running into the room, one of which says in a cheeky tone "oh, so sorry."
