I'm looking for an late 90s early 2000s(probably) softcore erotic thriller that I saw once. I don't remember much of it, but here is what I remember:   

The lead actress is a blonde. She has a small beauty spot on her face. Her right side, I think. it is not Shannon tweed.   

The penultimate sex scene has the lead actress fucking the hero, then going to sleep.   

After going to sleep, the antagonist from the movie shows up and holds a gun to their head.

He makes the hero get out of the bed and kisses the main actress.

The hero throws a (piece of luggage?) on the antagonist.

The antagonist then proceeds to tie the hero up (in the kitchen?) and has sex with the the lead actress in front of him. I believe the protagonist and the woman were planning on leaving the city/area together, and were talking about it sitting in the bed after sleeping together.

That's when the antagonist comes in and the woman sleeps with the antagonist.

The protagonist is then tied up in the kitchen and the woman is bent over the kitchen island looking at the protagonist while the antagonist has sex with her. Then the antagonist sits on a chair right in front of the protagonist and the woman starts having sex with the antagonist facing the protagonist, so her back to the antagonist.

The protagonist is still tied up but he tried to pretend that he doesn't care, but he still obviously does. After they finish, the woman takes the antagonist's gun and turns on him.

There is a possibility that this was on cinemax but I'm not sure.

Thanks!
