By Mutual Desire

Married for ten years, adventurous Kelly and Ryan are thrilled to take part in a fantasy come true—a week-long sex therapy study on a tropical island. The resort is first class, the sex off the charts.

Ryan’s always denied the issue that stands between them—the issue that threatens to destroy their marriage sooner or later. As they learn new sensual tricks from the other couples on the island, each x-rated assignment brings them closer to breaking down that barrier. When they do, will the pieces fit back together?
