Olivia and Brian Saunders once had a sex life worth bragging about, but after nine years of marriage, the sizzle has fizzled. Longing to reclaim their passionate past, Olivia purchases The Lust Letters, an adult novelty item guaranteed to spice up your love life. A zealous first round of play prompts Brian to read their cue for next time: share your deepest fantasy and ask your partner to fulfill it. Brian whisks Olivia off to Manhattan to pursue the fantasy he’s never revealed—he wants another man to pleasure her while he watches. Olivia never imagined her husband was concocting this scenario in his handsome head, nor did she imagine he’d choose Michael, their mutual, smoking hot friend from college, to help him out. Venturing into uncharted waters, Brian must contend with a heady mix of jealousy and arousal while Olivia surrenders to a man who’s fired up to have his chance with her. When three becomes two again, Brian’s only desire is to reclaim his stake on his wife and Olivia can’t wait to give him everything that’s his.
