Danger! Calendar girl at work.Posing nude on a tropical beach was a tough job, but someone had to do it.This was her first shoot, and the other models taught her the erotic tricks of their unashamed profession - and she also learned from the camera crew, whose expert lessons were far more personal and intimate.During the day, she stripped naked for the camera. At night, it was for the sex.And before very long, it was for both . . . Sun and sea and sand and sizzling sensuality.
