David walked round, examining his victim. He nodded to Alva, and without a moment's hesitation, she stripped her panties off and climbed onto the platform.

Gloria didn't believe what happened next. Alva slid between Mandy's arms, took her head in her hands, and forced it into the wide-open lips of her pussy.

"Suck it, bitch!" she said, and Mandy gave another groan and her mouth sank onto the cunt of the other woman.

Gloria gasped and put her hand to her mouth. It was far worse than she had thought. This was a terrible den of vice, a sink of sin that would have to be exposed.

And things got worse. David walked behind Mandy's thrusting, ass and ran his hands over her hot ass cheeks. Mandy moaned and sucked at him, her body rolling on the soft carpet. Slowly, David took the sides of Mandy's panties and slid them into the crack of her ass, removing the last of the minute protection she might have had.

"I'm afraid," he said slowly, "that I shall have to punish you very severely for this. I shall whip you until Alva has been sucked enough, and judging by what you made her take the last time she was in trouble, I think YOU are in for a very sore ass indeed."

Mandy groaned and sucked, hard at the soft wet pussy flesh. Alva was, leaning back, spreading her legs. She pulled a back support in and that allowed her to sit up and watch the beating that Mandy was about to get.

David lined up the whip and raised it in the air. It was a short-handled leather whip, with several braids of knotted leather running from the handle. He swung it through an arc and thrashed it down across Mandy's heaving ass cheeks.

Gloria held her hand to her mouth as Mandy screamed and heaved on the platform. Thin red lines ran all over her ass, and she moaned as Alva pulled her back to suck her pussy. David crashed the whip down again, and Mandy leapt higher, her mouth imprisoned between Alva's thighs, her screams muffled by the hot flesh.
