I'm trying find a Cinemax movie that was made in the late 90's. I know now that Colleen Brennan was the red head supporting female actress. I remember the plot slightly. A married woman started cheated on her husband with a strange man. The strange man ended up being partnered with one her college friends (who she had a lesbian experience with). The man makes the woman do things against her will. The man acts as the wife's sisters boyfriend. This gentleman and Colleen Brennan also convince the husbands secretary to get the husband to cheat on his wife with her. They video tape this and try to blackmail the husband. Also they video the wife and Colleen Brennan.
Scenes I remember:
Busty Blond Wife on the phone while husband is asleep forced to masturbate
Busty Blond and Gentleman have sex outside of the wife's house while husband an sister are in the kitchen
Busty Blond Wife and Red Head friend have a lesbian experience
Husband and Brunette secretary sleep together
Busty Blond forced to strip and have sex with a random guy at a bordello
This is what the red actress looked like if this is not Colleen Brennan let me know.
