There was a movie shown on the "after dark" series in the late 90s or early 2000s about a housewife seeking excitement. The gentleman who "discovered" her, took her deeper and deeper into a fantasy world where she experienced the dark side of sex. In one scene, they were at a dungeon club, once being tied to a pole in a room filled with men, looking and touching her body. In another, she was restrained in a lower level dungeon in a chair, along with other women, and they were on display for whoever wanted to take them.

What is the name of the movie and is it available anywhere? It is possible this movie also played on Playboy. As I recall, the title didn't reveal a lot on the actual pot of the movie.

I think the movie you are referring to is called Call Girl aka Nighttime Lover(1995). Starring Meilani Paul.

Good luck finding an unrated version of this film.
