No, she has to stay

You wrap your arms around her and caress her back. "I am not willing to let you go." She looks at you, distraught. "You said yourself that you liked to be bound and ****, just a moment ago. I keep you. You are mine." She blushes and bites her lip. "Can you move me out of the range of your wife, then? I could work in the kitchen. I can read and write. I could work in the treasury."

Now that thought had something to consider. Not only could you bend her over her desk in her prim and proper office, you could also keep tabs on the workings and whatever was going on in the office for census and exchange. Yes, indeed. And she could be called upon to feed your kinds, should the need arise.

You planned to have a lot of women pregnant by then, so that would not be a problem at all.

"Yes, I think that would be appropriate. I am still not tired of you, so ... prepare to be visited by your King from time to time." She bites her lower lip thoughtfully and nods. You sit there in silence for a while, holding each other in the arms, before she got up and fetched the towels. She dried you off gently, then herself. Helped you to get dressedm then dressed herself. You felt a pang of pain, a bittersweet goodbye. She curtsied, like she had always done, and vanished, as servants always do. You had lost this one, this special servant and very special chambermaid. Feeling the need to distract yourself, you decide where to go next.
