What does it mean when a girl sends you photos in her bra multiple times?

I am talking to this girl who asked for my snap when both of our friend groups briefly hung out with each other, and recently, she's been sending me photos as were talking with her in her bra with cleavage clearly visible with her tongue out. One time she sent me a picture of her in her bra and shorts in her mirror after the conversation was about to come to an end. The problem is was when I attempted to playfully react, saying "Now what's going on here" she responded with "wdym" in her bra. This has never happened during the previous days we were talking, and only happened at night. I don't want to make any unwanted advancements just in case its unwanted, so I want to ask here.

She also sent a top-down view of her in a bra and underwear. I can't tell if she is used to this or she's making a movie. obviously this doesn't happen to me much lmao
