There is nothing indecent.

(Thanks to DuskWolf for his work)

"There is no indecency in you, mother, only beauty. "The King smiled kindly, "Also, any man who would avert their gaze from you has no right to call themselves a man. They are no different from a eunuch. I say this as a king, a man, and your son."

Your mother blows her head as her hands still cover herself up. "My King, as a woman you compliments, honor me. However, as your mother, your compliments are misplaced on me."

You walk up to your mother and place your hands on her shoulder and say, "No, my elegant mother, none of my compliments are misplaced." You put a finger under her chin, lifting her head so that she is not looking you in the eyes. "In case you forgot, you agreed to teach me the ways of men and women. And if that is to work, I should see you as such."
