Upon the death of the previous King and Queen, their eldest daughter rose to throne. As part of the coronation, her youngest sister was presented to the new Queen Anyella, naked, trussed up, and gagged, ready to be collared. This was the position that she had been raised and trained for her whole life. It was traditional that the youngest same-sex sibling of the new monarch would be his or her first slave, and Ilae was more than glad to take up her new role.
Same sex slavery was not only accepted in the kingdom, but the norm. It was expected that those of rank would have harems of slave boys or girls, and slaves often wondered around naked except for their collars or wore skimpy costumes of their owner's choice. When allowed out of sight of their Mistress or Master, they tend to wear chastity belts to protect their property.
Younger sons and daughters of the nobility are often sold amongst the nobility - with it being considered quite prestigious to sell one's child to someone of higher rank. They are trained from the time they're children to prep them for this position, but are kept pure until they're sold (the repercussions for selling used property, especially to someone above you, are severe)!
Now that Queen Anyella has established herself, she is beginning to consider expanding her harem - no respectable Queen could only have one slave after all!
Needed: slave girls!
Queen Anyella will be played by rhea star

Also a possibility, an arranged marriage with a Prince who will become Prince Consort and have his own harem of boys.
