Joyce found her pleasure in the lap of another woman and would do anything to stay there — even become a Lesbian prostitute.
From the back:
Inn Of Sin
The heat was on their racket — Lesbian prostitution — so Joyce and Mara were sitting it out at a secluded mountain inn. They didn’t sit still long, for wealthy Avery Drake was also there and was looking for thrills — wild erotic thrills. More girls were brought in and the party started with a game called ”Skylarking”-three half clad girls doing weird things to one another on the floor in front of the fireplace. Before it was over Avery got more than he bargained for, and the girls did too.
