Looking for a simple scene or a whole movie: The scene I remember was like two husbands are playing chess while their wives starting having sex upstairs on the bed - they both have lingerie (pantyhose) and in the end they are scissoring / tribbing. The movie is from between 1977 - 1980s. One of the husbands looked like George Lucas - he had a beard and glasses and smoked the pipe while playing chess with the other man. One of the wives had very dark curly hair and looked like Latina (Mexican).
