"You bitch! You bitch!" Amanda screamed as the whip cut across her tits again. "I'll get you, I'll fuckin' get you when it's my turn! Suck him – aaaagghhhh! Oh God, no more, please!"

She heaved upward on the ropes and sank back down. Her little black dress top had fallen back and was getting in the way of the whip. Jack stopped and hauled Sammy up by the chain.

"Go push that dress back out of the way," he said.

Sammy sobbed and went over to Amanda. Slowly, she reached up and pushed the lacy black silk out of the way of Amanda's heaving, beaten tits.

"You bitch! You can stand there and let me get the shit beaten out of me!" Amanda stared at her sister with half-fury and half-pleading. "I'd do it for you!"

Sammy's fingers trembled as she pushed the dress round to Amanda's shoulder blades and made as sure as she could that it would stay there. She couldn't look her sister in the eye.

"You don't understand," she said defiantly. "You just don't like men, I can't stand them, I can't do it! I can't!"

"Back here!" snapped Jack, and Sammy turned, leaving her sister helpless on the ropes again.

"You bitch! You sit! I hate you! I hate you!" Amanda screamed as she watched Jack push her sister back down to his feet and line the cane up again. She stared at the thin line of wood as it trembled and then slashed across and into her tits. "Ouuurrrgghhh!"

"Just get your sister to suck my cock," said Jack lightly as he whipped her again. He leaned down to Sammy and grasped her by her long blonde hair. "You hurry up, slut. I'm so fuckin' horny I'm gonna bust. You fuckin' get on with it!"

He whipped Amanda's tits with another vicious blow, and the helpless woman's screams echoed from the stone walls.

"Your men scream that good?" he asked Sammy, and slapped her across the face when she didn't answer. "Did your men scream that good?"
