Five years ago Rick Wilson was a graduate student participating in Dr. Sarah Dalton's experiments on the male sexual response - as a subject. Now he's back with his own Ph.D. and a deep understanding of the female orgasm. The heat between them still simmers just below the surface and Rick is determined to have her. But he soon discovers Sarah has sexual hang-ups of her own. Luckily, curing them is the well-known "Dr. Feelgood's" area of expertise.
