Due to a recent failure on my part, Mistress C has suggested to my Mistress, who concured, that I seek out books on proper submissive etique, behavior, service, obedience, etc. for me to read and learn from. We are mostly non-BDSM, but if the information is worth it I can read past that which my Mistress's chose not to pursue. Mistress already has the Mistress Manual and At Her Feet. Mistress C's recomendation is books written specifically for the sub. Does anyone have any suggestions? Please?
