When Master's business calls him away, Molly is left in the care of Mephisto, the owner of a thriving local BDSM club. Molly is both excited and scared to be given over to Master Mephisto. His power and mysterious intensity have long compelled her from afar. Molly finds herself immersed in a world of strict commands, pervasive sex, and creative torments. Over the course of a week, Mephisto strips away privileges Molly took for granted and forces her to understand and acknowledge the depths to which she can be made to submit.
But a surprising conversation on the last day threatens Molly's worldview, as does the strange closeness that develops between them. As the time of Master's return draws near, Molly finds herself deeply and inexorably changed.
