The Interrogator rubbed the Spy's bare ass, caressing her athletic curves. He smacked it, watching her pale skin turn red. She seethed, bent over his lap, not struggling or whining. He began to finger her roughly, interspersing the fingering with more slow rubbing and sharp smacks.
This went on, and eventually the Interrogator reminded the Spy that he would free her if she chose to be helpful. She refused to be, so he set a large vibrator against her clitoris and clicked it on. It whirred like an electric toothbrush, only louder. She writhed subtly under his hand. She began to lose her composure as heat invaded her face and flesh. He held it steady, easing it on and off, applying waves of pressure to her cunt, observing calmly as she inched towards the brink of orgasm.
But the Spy didn't reach orgasm. The Interrogator almost gave it to her, but he withdrew his hand in time for her to scream with rage and struggle in her chains.
She lay on him, panting. He began to rub her ass again. "We'll start the routine over. It will repeat until you choose to be helpful."
She smirked at the stone floor of the room. "Don't underestimate me. I can orgasm without your permission."
He started to finger her clit. "You sound ridiculous," he said, half-chuckling. "You threaten me with humiliation for you and satisfaction for me!"
She realized what he meant--what she'd said. And he brought back the vibrator. It was more intense this time, and she had to bite her lip to keep from moaning.
"Getting closer, I see." He sounded distantly curious.
