Erotic Fantasy Roleplay- (F for DM style narrator!)

This idea is a bit unique, and dark at times but at its core, this is meant to be a Fantasy Adventure with erotic elements. Basically my idea is that my character is the youngest daughter of a King who’s nation has been at war with a fierce rival for a couple of years now and the war weariness has been quite strong. Along with her brothers, the King has been off fighting for months and had only recently returned from the frontlines to attend to some duties. Soon after the King, and our entire family is betrayed by either one of the King’s generals or even one of his disgruntled ministers, leading to the massacre of most of the family (besides myself). The idea behind this role is for my character to escape the castle and the capital city itself, but with the intention of going back, overthrowing the traitors and claiming the throne for herself (with sexual elements of course!) 

Hit me up and we can discuss some more specific ideas to intertwine into this if you'd like!
