Yes

You honestly never considered making her into one of your concubines. The real reason you started this whole event is because you're greedy. You don't want to let your mother relinquish her bond to the royal family; you're also want to enjoy yourself feasting on her flesh. But since she brought up the matter of her becoming a royal concubine, you can't see any reason to deny her. It is not uncommon for a King to have concubines that are wedded to a loyal subject of his Kingdom. In fact, two of the previous King's sexual servants were married. Now, none of them were married to a noble, but that's not the issue. It may be VERY RARE, but it happens ... At least once.

The thought of having the former Queen as a servant to your cock has a certain ring to it. A ring that excited you and your cock, which is still lodged inside of her.

Your cock's increased excitement certainly does not go unnoticed as a moan escape Lady Beatrix's lips, from your cock filling up the tight confines of her pussy. Prompting you to groan, "Yes, my Lady. That is what I, your King is commanding you to become,"

To be honest, if the famed Lady Beatrix had her wit about her, she would have turned this down on the spot because it could have a negative repercussion. But it's hard for her to think, being overwhelmed by the whole event, and at the same time being stuffed with your enormous cock. She glances over to the Queen's throne, a throne that only a few minutes ago belonged to her, as if to say one last goodbye before turning her gaze towards you and saying, "Than as my King's concubine, I will do my best to satisfy and sate my King's royal sexual urges."

As if signaling her acceptance into her new life, Beatrix slowly lowers herself down onto your throne so that her knees and sitting on the cushion of the seat and her hands are on the top rail with her tits resting on the back. Beatrix says. "Take away my last dignity and claim me as your concubine."

From this new position, you can grab her ass and finish thrusting your cock inside of her. The previous King was so distracted by his enormous concubines that his cock rarely found her pussy, unless it was for creating an heir. That's why her pussy still felt like a vice grip around your shaft. Causing you to moan, "Oh fuck!"

She moans back, "Yes, your fucking your concubine... You're going to coat her womb with your seed, so the world knows... sigh... no one will respect... ugh... me of the... ahh... mother who... ohh... give birth to the... fuck King!"

Much to both of your surprises, you suddenly feel her pussy rippling around your cock, and you uncontrollably release your seed inside of her. You shoot rope after rope of your warm seed inside of her until it's free-flowing down her legs and onto the chair.

She must have notice?d it because she looks back at you and says, "My King, your seed is a royal treasure and the key to the future of the Kingdom; you mustn't leave it lying around for anyone with nefarious intentions to come and take." Before scooping it up with her hand and slowly licking her hand clean.

You are left so awe-shocked by these actions that she can slide off your deflating cock and walk towards the door before you notice and say, "My Lady, where are you going?"

She quietly answers, "With your royal task completed, I believe it's time for me to make my leave and return to my future husband."

"With no clothing?"

Beatrix looks down at her pussy which is currently dripping your warm seed. "You were right, my king; the world must know that my womb is disgraced."

You watch in pure shock as her naked ass walks out of the hall with a large glob of your cum hanging from her pussy.

Midnight that night

That night you are awoken from your sleep by the banging of the door and Sir Dietrich calling, "My King, we request to consult you about an urgent manner."

You slowly wipe the sleep off your eyes before calling out, "Then enter,".Sir Dietrich and Lady Lisandra, the former King's lead concubine, come storming in dragging one of Lady Beatrix's handmaids.

Sir Dietrich, "My King, please forgive our intrusion, but this person just attended to comment the gravest of treason."

"And what act that the delicate woman could have done that was so grave that it required my attention at the darkest point of the night."

Sir Dietrich "This scum has attended slight the Queen's good name and foolishly her name as one of the good Lady Lisandra's charges."

The Handmaid cries, "My King, please believe me, I only did as my Lady ask!"

Prompting Sir Dietrich to slap her across the face, "Silence, you wrench."

You quickly understand that there are only two people in the world that know your mother is actually your concubine. Meaning that everything this Lady said is true, although you never expected your mother to actually register herself as your concubine. Seeing enough, you quickly command, "Sir Dietrich, Stay your hand! The crime you claim this woman has committed is not possible because there is no Queen whose name would be slighted. In fact, everything this good woman has said is true."

Sir Dietrich is left speechless, so Lisandra states, "Wait, the Queen actually wishes to be on the list. Why would she do that? She hates the concubines!"

"Lady Lisandra, I know it's late, but please listen to the words I say. This country has no queen; the former one revoked her title to seek marriage with Arch-Duke Franz Jacques. But after much discussion, she realized that her duty to the country was not finished and placed herself as one of my concubines."

Sir Dietrich and Lady Lisandra both look like they don't fully believe what you said. However, Sir Dietrich quickly shook his head off and thought carefully before saying, "We must take control of the situation and spin it in a way that makes us look good."
