Exactly what you said, you might have to take her.

''Hm... I was half joking, but...'' You pause with a smirk. ''You are blushing so much, I just might have to take you with me. I have a beautiful maid named Carol who could use another cute maid to help her with the housework.'' You smirk.

Grace gasps, ''But... A commoner like me... Living in the castle of Resh Kar? I wouldn't be allowed even close to it!''

''You would be allowed. I'm a prince, remember? Whatever I say, goes.'' You shrug your shoulders. ''Besides, Carol would probably enjoy having another maid around. I've only got the one, after all. You would be a lower ranking maid than her, of course.''

Grace blinks at you. ''B-but... What if you get bored of me? If I get kicked out of the castle, I would have n-nothing left!'' She says, it seemed like she had taken your joke a little too seriously, but upon giving it some thought, why the hell not?

''Me? Bored of a beautiful woman like you?'' You ask, acting incredulous. ''You must be mistaking me for my older brothers, I'm not as much of a prude as them you see. I like to enjoy women to the fullest.''

Grace giggles nervously.

''Besides, I would never kick anyone out of the castle unless they were a threat to me. So, don't worry about that. The royal family is rather lenient when it comes to our staff.''

You were joking at first, but the more you talked about it... The more you liked the idea. You never had much contact with commoners and so you never really pondered the idea of taking some of them with you to the castle, but now that you are in front of such a beautiful woman... You have power, so why not use it? You would be bettering this woman's life, anyways. Maids at the castle have little too worry about as far as their needs go.
