Okay, this movie has been haunting me for like 15 years now. Last time I saw it was mid to late 90's. Now I don't know if anyone can help me with this, as this is one of those Cinemax After Dark, or HBO movies

(hehe, I know).

I haven't seen it from the beginning, but do remember the parts I've seen:
The main character is a young blonde woman. (Once again, I haven't seen all of this movie, so I don't know exactly what's going on, so I'll tell you the parts I saw).This guy starts calling her (in the middle of the night, at work, etc.), seducing her over the phone, making her touch herself. One particular scene of this is when she's at work. He calls her up, and she starts running her fingers over her legs and stuff while he's talking to her. A woman in her office notices her doing it. Then the other time was at night when she was at home in bed.
One night she does actually go to see him, and she shows up at his place, wearing a black robe. He's sitting on a couch, and she crawls over to him on her hands and knees. He takes her robe off, and she has a sexy pink nighty on underneath. He grabs her and kisses her, then they end up having sex on the floor. Now I think this guy was running some sort of prostitution ring or something (which he ends up getting her involved in some how), because at the end she has him arrested. It shows him offering a girl to a bunch of people, then all of a sudden one of the guys there (obviously an undercover cop) pulls out a gun, and the movie ends with the blonde woman standing there watching as everyone's being led out in handcuffs.
I know what I've provided isn't quite enough info., but I was seeing if I could find the name of this movie online or something and ended up coming across this website. It's been a mystery. Figured I'd take a chance!
