Head Talk is a weekly TV show with revolving hostesses.  Is that anything like Blazing Stewardesses?  Each week, Porsche Lynn, Rachel Ryan or Keisha demonstrates oral sex on both men and women.  As a plotless exercise in fellatio and cunnilingus, this really isn't a bad video.  The three leading ladies each throw themselves into their work and more enthusiasm is seen here than in a dozen of your everyday throwaway shows.  The rarely-seen-these-days Porsche Lynn shows the youngsters how to do it.  Not that she's a doddering old lady.  Keisha, also a rarely-seen face and figure, lets us in on some secrets of snatch munching that are a real insight.  If you are tired of trying to pick out a story where one exists only in the director's mind, this wall-to-wall feature is a good entry in that field.
