Sit at your desk and ask Sara if she has questions about the quiz

You are a professor, after all, and you do still want to ensure your students succeed.

Sara just giggles and walks up to the front of the room. "Did you like my little show today, professor? Or did it make it too _hard _to focus on the lecture?"

You start to stammer out a response, but she shushes you with one wet finger.

"I don't actually care. I just want to tease you a little bit before the fun part." And as soon as she says that, she slams her knee right up into your balls.

You drop like a sack of bricks, and all you can think for the next few minutes is how unbelievably painful this is.

But when you hear the click of a cellphone camera, you have to open your eyes and see what they've done.
