Frustration

"I...I choose frustration" Amy said. She didn't know what that would mean, but it couldn't be as bad as pain or humiliation, right?

"Hmmmm," Bianca said, "I'm glad. Although I'm surprised you didn't choose humiliation, considering how much it turns you on."

Amy blushed at that and started to object, but her denial died unspoken. She knew Bianca would see right through the lie.

"For this one, I'm going to have to tie you up," Bianca said, "get on your bed."

Amy got onto her bed and lied down. Bianca, with business-like efficiency, pulled some silk rope out of a dresser drawer and tied Amy's hands and feet to the four corners of the bed. Then, from that same drawer, she pulled out black silk scarf. This she tied across Amy's face, shutting her in darkness.

The first thing Amy felt were Bianca's fingers, lightly dancing over her skin. They started at Amy's neck, slid down her sternum, circled her belly button and slid lightly back up to Amy's tiny boobs, circling her nipples until they rose up hard as steel. Her fingers traced slowly down, circled her belly-button, then, slowly, moving in tiny spirals, they worked their way down over her newly hairless mound.

Amy gasped when Bianca's fingers ran over her clit, then down her lips. She felt herself open up as she grew instantly wet. But then the fingers moved, lightly tracing over her inner thighs, then up her sides to her ribs and back to her nipples again.

The cycle repeated itself and Amy grew more and more aroused, until she started to gyrate her hips, trying to press herself harder against Bianca's fingers.

Finally, Bianca started rubbing Amy's clit directly, her fingers making little circles around it, faster and faster. Amy felt a finger from Bianca's other hand slip inside her pussy and curl up to rub her g-spot. She felt an orgasm building inside her. Amy bit her lip as she grew closer and closer to cumming.

Then suddenly, nothing. Bianca pulled her hands away just as Amy was on the verge of satisfaction. Amy heard a whine of frustration escape her lips like a lonely puppy. So this is what Bianca had meant by "frustration."

"Please, don't stop," she said. She could feel herself blushing as she spoke--it was humiliating acknowledging that Bianca had gotten to her.

"Oh, you want me to continue?"
