Mephisto

 Molly is a 24/7 slave dedicated to serving her Master. When business calls him away on a weeklong trip, he arranges to leave her 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.

She 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 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.
