Tom Byron's divorced and now can't get it, so he goes to Dr. Ginger Lynn for sex therapy. While at the clinic, he peeps all sorts of people (usually credited under other names) having all sorts of sex.
Ginger's the best, essaying first a solo on her bed until joined by Lynn Ray for some scissor action until Jerry Butler walks in to double b.j.s, reverse cowgirl from Ginger while Lynn sits on his face, and finally anal doggie from Ginger. Almost as good is Ginger's finale with Tom that starts with back massage, progresses to b.j. and pussy-licking, then doggie and mish with a slo-mo facial finale.
