Fifty Shades Shadier (Fifty Shades of Silver #2)
Phil Torcivia

Desire for Bea’s butt still dominates his dreams, and when she proposes a route there, Mormon cannot resist. They continue their sweltering sexcapades, as Mormon learns more about the disturbing past of his hungry, obsessed, and insatiable lover.
While Bea wrestles with her sex toys, Mormon must deal with the fury and cock-blockage of her Grandmother, who came before her (of course), and make the second most important decision of his life—whether or not to reveal that he has had a vasectomy.
