What happens?

I give Amanda a task that she cannot possibly complete, and punish her when she fails.

"Okay, I have an idea, I'll give you a little task," I began, enjoying the control I longed to assert on this troublemaker since I met her "and if you do it, not only will I give you your clothes back, I'll even make the other girls strip."

Jennifer and Cameron looked at me with shock, but I assuaged their fears with a subtle wink when Amanda wasn't looking.

"Okay, what is it?" Amanda, knowing how this typically works, didn't get her hopes up too much, as she should.

"You have to do 25 push-ups," I could see Amanda's face light up, letting her guard down and believing there was a chance this could be done if she tried hard enough, and I couldn't have her go on and do so, so I continued, dashing her hopes "In one minute."

I had heard from an old acquaintance of mine that entry into the airforce required a test of 18 push-ups per minute to enter for women, so this task was practically impossible, and I assumed (correctly) that Amanda knew that, since the color that had returned to her face was suddenly drained from it.

The rest was just us watching the inevitable unfold, Amanda got down on the ground and began doing push-ups, I started the timer on my phone and watched as the girl began trying to pass the test in vain while I counted out her progress, she had managed about 12 when the timer ran out, but I kept quiet and let her continue, I showed the timer to Jennifer and Cameron, and just as Amanda reached 22, barely able to lift herself off the ground, I yelled out "Time's up!"

Amanda, sweaty and breathless, rolled over without any inhibitions, she was splayed out on the ground, her heaving breasts, and shaven pussy in plain view, I consoled the girl in the most condescending voice I could muster.

At that point, I noticed that her nipples seemed to be a little stiff, I wondered if all of this might have caused some arousal in the girl, but I couldn't tell that clearly since she was covered in sweat.

"Unfortunately for you, you failed the task," I turned to the girls who looked like they were seeing the most amazing show in their entire life "What do you think, should we punish her for failing?"

The girls sounded off in agreement, and I pondered what would her punishment be?
