You are first to talk

Understanding that you have basically tricked your mother to whore herself out to you, and you don't want her to completely hate you as she whores herself out to you, so you tried to do this as gently as possible. You look her in the eyes with the softest of eyes as you can and says, "I am deeply sorry, but with you marrying him, it creates an issue where the Noble may start believing he is claiming the title of King."

Sensing your care and sincerity, your mother looks towards her feet as she contemplates what you have just said, allowing you to continue speaking uninterrupted. "Thus, and mom trusts me that I am deeply sorry that I have to do this, but I can not let you keep the title."

She says, "I understand." before looking back into your eyes. Her eyes show you as deeply defeated as she is. In her eyes, you can see that she knows what you know, and that is that your mother doesn't actually own the clothes she is wearing or anything clothes at all. They all belong to the state, or more precisely, they belong to the one who holds the title of Queen; since she no longer holds that title, she must return them. thus she says, "I see now why you cleared that room, and I thank you for allowing me to return everything that belongs to the title in private so that I could keep my dignity." While hand tender, soft hands start pushing on the shoulders of the Queen's gown. She takes her time pushing it off her shoulders, hoping that you will stop her but knowing full where that you can't.

Sensing her hesitation, you attempt to reassure her by saying, "Fear not, I will not have my dearest mother exposed to the public. I will have someone bring clothing that you may keep, and you can also use the secret exit to preserve your honor."

She once again blows her head and says, "Thank you, my king," Before finishing pushing the gown off her shoulders so that she is now standing before you in a peace thong and matching corset. Both of which also belong to the Queen's tilt, so her fingers quickly start working on the knot holding the corset on. But she quickly stops when she looks back up towards you; her nipple fingers freeze before her arms quickly come up to cover her exposed cleavage. "Ah.... my King, can you avert your royal glance. I am indecent."
