Breeding the Duchess
Rose Wetter

Edmund, the Duke of Leeds, cannot produce an heir. Desperate to carry on the family title, he approaches his wife, Sophie, with an unusual request. His brothers look like him, and no one would question the parentage of a child if one of his brothers sired the child. The duchy and his home and title depend on producing an heir...one way or the other.
Horrified at first, Sophie considers the request of mating with all three of her husband's brothers. But after careful thought, the idea of having all four men at the same time, her husband and his three brothers, stirs a lust inside of her neither she nor Edmund knew existed.
