She doesn't notice

Mentally manipulating Miss Nolan you leave her completely oblivious to the pictures the students are snapping and you begin to wonder how far you can push your powers.

A quick snap of your fingers and her bra disintegrates away, the thin material of her blouse doing little to hide her nipples as a few more students begin to take a lot of notice in their teacher.

A cold breeze is still blowing through the yard, and as the air hits her nipples they begin to stand out like bullets from her blouse and for a moment she pauses, seeming to suddenly be aware of her situation.
