Forbid her to touch you.

"I didn't allow you to touch my cock", you say, and look at her sternly. She blushes and withdraws her hands immediatly, looking guilty. "And I am pretty sure your mistress did not allow you either", you add. Now you have her full attention, and the look on her face is one of fear.

"Please, Sir, don't...", she starts, but you interrupt her: "Shut up, ****!"

She closes her mouth and looks down on the floor. "You will go to your mistress and tell her what you just did", you say. "I am sure she will punish you accordingly." She nods, biting her lip. "What's your name, ****?", you ask.

"Jennifer", she replies meekly.

"So, Jennifer, I am sure, we will see us again. Send my regard to your mistress and tell her, what a bad **** you've been. It seems you don't have your urges under control. Go now!"

You watch the blonde woman leave and admire her backside, as she stumbles along the corridor. For a moment, you wonder what you just missed, but at the same time, you feel incredibly powerful by imposing her rule on her. It's worth more than a quick handjob: The feeling of power and how that girl reacted to it."
