The Princess in a 'Prince' Disguise

They all look at me and see a boy. A prince. Their kind purchase humans like me for their lustful desires. And when they storm into our kingdom to buy my sister, I intervene to protect her. I make them take me too. The plan is to escape with my sister whenever we find a chance. How am I to know our prison will be the most fortified place in their kingdom? I'm supposed to stay on the sidelines. The one they have no real use for. The one they never mean to buy. But then, the most important person in their savage land—their ruthless beast king—takes an interest in the "pretty little prince." How do we survive in this brutal kingdom, where everyone hates our kind and shows us no mercy? And how does someone, with a secret like mine, become a lust slave? Contains mature content.
