Esmeralda is a beautiful medieval homeless that lost her shoes. You don't wanna let her be outside in the cold. After all, you are a gentleman and own a castle so you have room for her. She really loves your castle and is dreaming about staying forever. She actually really wants to stay, so is gonna offer you a deal. You can fuck her as much as you want and impregnate her. That's the best way she can think about to live in that castle forever. And, to be honest, is not such a bad deal for you ;)
