Delving Deeper is the fourth book in the award-winning XXX-rated Letting Go Series. In it, Jennifer continues to explore her sexual submissiveness under the guidance of the handsome and talented Sir. So far, their relationship has been based almost entirely on sex and obedience, but that all changes when Sir finally reveals details of his personal life and tasks Jennifer with helping him close an important business deal. Will she be up to the challenge? And what effect will success—or failure—have on their deepening relationship?
