The dress drops to her feet, but she doesn't kick it aside. Instead, she waits and watches you, measuring your pain. Her hand forms the cup again. Then, a fist.
You reach down and grab your testicles in a firm grip, then squeeze until you can feel it in the pit of your stomach. She gives you a nod, but keeps her fist clenched, waiting, watching to see if you break. 10 seconds pass by. 30. A minute, before her hand looses.
And then tightens again. For forty seconds this time.
