Stimulate her clit.

The remote control has several buttons and sliders, and you quickly notice the three bigger buttons "clit", "vagina" and "anus". You decide to start with clitorial stimulation, push the button and set the slider to a lower level. The Asian girl immediatly reacts with a shudder, and you hear a faint buzzing. Dutifully, she tries to concentrate on her task, and you lean against the wall, watching her for a while. After a few minutes, her moves become shaky, her breathing gets louder and she bites her lips.

"You just tried to clean that spot there three times and failed every time," you tell her sternly.
"S... sorry," she replies meekly, takes a deep breath and then frantically rubs at the spot on the floor with her cloth.
You give the slider another nudge.
She gasps, shivers and a moan escapes her lips. Her right hand squeezes the cloth tight, but she has clearly trouble focusing on her task.

"You don't seem concentrated on the order I gave you, stupid maid," you say harshly. "Was I not clear enough? I want this floor nice and tidy!"
"Fffffff... yes, sir!" Her answer sounds slurred.
"Good," you say. "Or else I have to punish you."
"No, sir, please don't. I - I clean your floor right away, sir."

She really manages to concentrate once more and focuses on the dirty floor. For a moment, you admire her for her willpower. You still do hold the key to brake her willpower in your hands, though.
