There was a Cinemax after dark movie or TV show episode that I remember, but just can't think of the name of movie/series. The story was about these two girls who were in college, a brunette and a red head. The red head worked as an escort on the side and got the brunette to start taking on clients. I think there was a limo scene somewhere in the middle with the brunette. It ended with the two girls almost getting expelled, but the red head convincing the dean to change his mind.
