The Male Concubine by Chris Bellows
The Princess of a small African country is afforded the company of a human teddy bear - a blond boy of unknown origin. The Dominant and devious nurse uses the boy to teach and mold the Princess into the most Dominant of females, denying the boy clothing and using his anatomy to instruct the Princess on the weaknesses and vulnerabilities of the male gender. In time, an evil doctor castrates the boy and inserts penal implants... thus the Princess can have her cake and eat it too! No risk of procreation, but a permanently stiffened organ constantly available to satisfy her girlish pleasure.
Upon the death of the King, the Princess becomes the Queen, where her unusual upbringing imbues her with an aura of power and admirable self-confidence. She easily assumes her duties of omnipotent ruler, having been well served in her youth dominating her male companion. The Queen finds the Palace dungeon to be an ideal facility for the imprisonment of border intruders and treasonist, foolishly proud males. Her goal is to turn her dungeons into a showcase of her power.
Written in the traditional 'gothic' style of Chris Bellows, the male concubine undergoes thorough domination by the Superior sex, including alteration and modification, extensive CBT, feminization, canings, body piercing and constant humiliation. Other miscreant males undergo the embarrassing procedure of forced circumcision and find themselves serving as beasts of burden on the doctor's farm.
