S: A Journey into Servitude by Philippa Masters
S's descent into total submission is almost complete, her love of humiliation and subjugation now unparallel in its intensity. Her rigorous training continues as she is taken to her master's palace and proudly displayed as his plaything. She becomes more and more skilled at pleasuring her master and his friends, taking a lewd and perverse delight in having her sexuality rigidly controlled. But she yearns for a sign of affection from him, and dreams of being his only pleasure slave - will he ever be able to admit his need for her?
