You wouldn't call the king's concubine lowly.

You line your cock up with her slit and give it a slight push so that she knows it's there before saying, "I would love to see those who dare call a king's concubine lowly, but yet they perform indecent acks all the time for the shake of the kingdom."

You start rubbing your cock head up and down the outer edges of the slits causing her to moan in lustful heat as she asks, "A king's concubine, is that what has become of me now."

You kiss her on the lips, causing her to moan into your mouth. You can tell that her hormones have long ago taken a stranglehold over her mind, and she will not agree to just about anything you say "I wouldn't go telling any nobility that, I doubt they would be happy to hear that, but." you press your cock into her so that the cock head slightly splits her "aren't you haven't sex with the king for the shake of the country."

You give her a moment to look down through the valley that is her cleavage and toward your cock. Although it might just be the tip of your cock head, your dick is definitely inside her. Not only can she feel it, but she can also see it. Thus she slowly answers, "That I am." Signaling that she finally fully accepted her fate as basically your new fuck toy.
