I'm trying to find out the names of two films, which I only remember a few scenes from:

1) Its probably from the late 80's or early 90's. Probably a Hollywood movie. A guy is investigating a case in private, it might be a murder, together with a woman. One of them I probably related to the case somehow.
The scene I remember is that the woman and man while investigating, end up staying at a motel. The woman takes a shower, and he happens to stand in the bathroom, she asks him to help him soap her in. It ends with them having sex.

2) The second film is most likely an x-rated film, 60s or 70s. Its probably German or British. There are a lot of short stories or scenes not related to each other in the film.
Two scenes I remember: A man visits a shop where a hot woman works. He is fat and has a cigar. They meet and sit together. He wants to see and touch her panty, she instead takes off her top and removes his cigar, the scene ends.
The second scene is two women fighting, they end up tearing each others clothes off and have sex. A man comes in the room, and they sexually abuse him...
