Trekkies know all too well about Angelique Pettyjohn (Heaven St. John) from Star Trek: The Gamesters of Triskelion, and how she starred in some X's. The top jpgs of the screenshots are shots from the TV show.
In Body Talk (1980) she plays an earthling in a Camille/La Traviata mode.
This XXX was made when she was no longer a spring chicken but more a milf-type.
Kay Parker plays her friend who's also involved with another younger man.
