For His Eyes Only (1989)

Overworked husband, Cliff, reads his wife's, Emily, diary of how lonely she is with him away so much. To make up for his neglect, Cliff enrolls Emily in a "special service" Boutique, where Julian and Ana first arrange a tryst for Emily with Peter North, who has also had a scene with Rose at the poolside. On following appointments Emily is with Mike Christopher, and with Nina Hartley who begins her scene as a cosmetologist. Cliff observes all of Emily's attempts to find happiness without him through a two way mirror. Ana then shows Emily what Cliff's involvement has been, which just makes Emily mad at Ana for spoiling the fun. In the end, though, Cliff finds time to take off for a vacation with Emily, showing that he needs no help to pleasure her after all.
