You're doubtful

You look at Professor Garrison in shock, astonished by his demand, your mind struggling to catch up with this unexpected development.

"Professor? You can't mean it...you're teasing....right?"

"On the contrary Miss Carter. You dress like a strumpet in my class, obviously under the impression that showing off your body is going to cloud my judgement and allow you to skate through without effort. Well, now I'm giving you the opportunity to make a thorough job of it. Take off your top and show off the assets you think are so special. You can't pretend to be shy."

"But...Professor..." you stammer, "Here? Someone could...could walk in..."

"What difference would it make? You're eager to display your body in class. What would it matter if someone else besides me saw you showing off a little more?" He looks at you with a sneer. "Very well, if it worries you so much, go and lock the door. Or leave. I frankly couldn't care much either way."
