You increase the . A little.

This time when the blow lands Diana gives a sharp little yelp, still glaring back at you. You increased the **** of the blow, but it's still less than Rose Newton received, though you doubt the young headmistress knows that. Determined to get this over with, you smack her again, drawing another yelp, following by a snort of anger as she stands up and whirls to face you, stepping very close and waving a furious finger in your face.

"I'm warning you Mister! If you think you can play games with me you are sorely mistaken! I told you I wanted this just as hard as Miss Newton and I meant it! Now either you can comply with a direct order or you can start looking for other employment! I will not be trifled with and I will not be patronised! Am I understood? Or do I need to use smaller words, Marine?"

Her scornful words sting and you search for a response to the lovely and furious half naked woman standing in front of you.

"I can take anything that vicious little bitch can take and more! You do what I tell you, and you do it now! Are you man enough Marine? Or should I get someone in here who can do the job?"

"Bend over the desk," you bark at her, your own anger spurred by her taunting. You grab her arm and turn her, pushing her towards the desk. You think you see her lips quirk in a momentary smile as she bends over and raises her ass again, but you know longer care. You're going to give her exactly what she wants, and wipe that smug look off her face.
