Yes

"I suppose," Valerie said, "since this is our first day, and I have such a long time to train you properly, I can afford to be lenient just this once. Don't come quite yet -- you're such a randy little whore that I'm sure you'll explode as soon as I give you permission, won't you? And that's no fun. Come over here and hump my leg."

"Wh... what?"

"You heard me. That's how randy bitches get off, right? Come here and hump my leg like you mean it. I'm not going to give you permission if you can't convince me you're really trying to get off. Oh, and I wish you couldn't say any words except 'Mistress' until I said otherwise."

Jessica moaned. She tried to protest, but the only word her mouth would form was 'Mistress', and that just made her hornier. With her abdomen and thighs practically cramping with need and her hands still tied behind her back at a painful angle, it took her quite some time to get up on her knees, scoot her way over to Valerie (who had taken several steps back just to watch her struggle), and wrap her thighs around one high crimson boot.

Jessica gasped at the new pressure between her legs. Her body screamed at her that this was what she needed, this pressure on her thighs, this zipper being pressed into her clit, and at the same time that it was too much. Tears poured down her face as she rocked herself back and forth a little, trembling with overstimulation.

Valerie watched her, unimpressed. She knew that if she wanted to come, she needed to be more enthusiastic, prove she wanted it. She **** herself to buck harder, faster. The painful bruises on her ass were a welcome distraction from the sensation of hitting the point of orgasm again and again and clenching up there, painfully, unable to finish. Please let me come, she tried to say, but all she could say was "Mistress," and then scream at the sudden surge in need. It was too much. She was sure that she was going to pass out.

Valerie opened her mouth to speak.
