Slave Sentence [EPUB ebook] 

Chained in his own dungeon, former master Mc Givern is at the mercy of punishments far crueller than any he ever devised. The torture he receives is perverse, degrading and always sexually humiliating. Determined to overthrow his gaolers he forms an uneasy relationship with the most sadistic of his female tormentors and agrees to all her demands in his bid to regain control of the castle. But his greatest fear is that he will come to enjoy his bondage before he can return to his dominant position.
