Man was tied to chair by a white, short haired woman, clearly the villain and a competitor. I seem to recall she was something like a professional assassin, as was he. He probably spurned her attention in an earlier scene. He had a girlfriend. She was going to kill him but before doing so forced sex on him (tied in chair). The idea was to make him be unfaithful to his girlfriend and, what is worse, to leave the world knowing that his nemisis might become the mother of his child. She proceeds to have sex with him but is interrupted when a man enters the room and shoots her. She dies and the man unties the victim. Movie proceeds but I feel asleep. This was on regular cable so it was not an X rated movie. I would love to watch the whole movie and find out what the whole things was about.
