Somehow it seems like she heard about hypnosis.
Somehow she overcame her shame (heh).
She sits straight up, she doesn't care that she is only in a bra. I point at her.
"Hey, Miyazaki. Why is that thing covering your breasts? It's shameful that you're still wearing that!"
"Yes, master. I have to undress..."
"Actually, hold on."

She hurried to take off her bra, but I commanded her to wait.
"Why don't I help you take it off?"
"Huh?"
"It's the teacher's duty to guide the student through behaviors she hasn't learned yet."
"Ohh...I'm sorry for being a burden..."
She became apologetic, and from then on it was easy to get her to show her own breasts.
Now for her mind...
