"You want her to suck me off?" he asked Amanda.
"Oh God!" Amanda moaned. "Do it, Sammy, do it! For me, ohhh no, no! Fuuuckk, you cunt, suck him!"
She writhed on the ropes, her arms pulling at the rest of her body.
Sammy looked up at her sister.
"You know I can't!" she screamed. "I can't stand a man near me, I'll die!"
"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?"
"Yes!" Sammy shrieked. "Yes, they did, now leave me alone! I won't suck your cock, I won't!"
She struggled away on the floor, ending up as far away from him as the chain would allow her, crouched on the cold stone, holding herself, trembling with fear and disgust.
"Ohhhh God!" Amanda screamed. "Let me do it, I'll suck you off, honest, I will, I'll do it! Please!"
Jack flopped whipping her and stood for a moment, his cock jumping and heaving with lust. He looked at the two blondes, making up his mind.
"Well, now, this wouldn't be the right way to do it, but I gotta get my cock sucked." He went up to Amanda and leaned close to her. "I bet you could learn to suck cock for a long time and not make it come – like when I had your sister up there and was whipping her. Sound good?"
"Yes, yes," Amanda whispered. "Let me down and I'll do anything you say, anything!"
"Good," said Jack. "You'll have to forgive me, but I have to make sure your sister is properly hung up while we do this."
He looked around the dungeon. There were a great many pieces of equipment, and he wasn't sure which one he wanted to use. In the end he picked a massive rectangular metal frame. Not only could Sammy be strung out nicely from its corners, the whole thing could also be turned over and back again. So he could have Sammy horizontal, or upside down, or anyway he wanted her.
"Too bad, little sister," he chuckled. "I gave you your chance and now you'll have to learn the hard way."
He got the frame positioned as he wanted and went back to the cowering, helpless blonde.
"Up," he said, dragging her to her feet by the chain.
"Stop it, please!" Sammy wept, all her fury gone in the surge of tenor running aver her. "Oh don't do it! Please don't do it! I can't help it, I just can't have sex with men, I can't!"
She struggled as he hauled her over to the frame. Many of her victims had hung on that frame, pleading with her as she whipped their asses, and when she was in a particularly vicious mood, their cocks and balls. Sammy loved to see a man's helpless cock bounce as the whip landed across it.
She screamed as Jack fled her wrist to the leather loop hanging from the top corner of the frame. Sammy was pulled up almost off the floor by her one arm. Then he took her other arm, lashed that to the other side and pulled Sammy right off the floor until she hung almost as Amanda was, but with her arms outstretched like a figure Y. She moaned and wept, but Jack just laughed at her and walked behind her tossing, heaving body.
Sammy groaned in terror as he grabbed her ankle and pulled it out until he could tie it to the bottom corner of the frame. Then came her other foot, lashed to the far corner until Sammy hung in the frame like a big letter X, utterly helpless. Then he ran his hand down the front of her white tap pants.
"Oh boy, that's nice!" he said. His fingers reached the top of her blonde pussy-mound, hardly protected by the thin silk of her pants.
"Leave me, oh please, leave me!" Sammy sobbed.
Jack ran his fingers slowly lower, while Sammy's body tossed and writhed in almost mortal fear. Inch by inch, he ran down the inside of her panties, over her pussy hair and to the very top of her cuntal crack. He looked up into her staring eyes.
"Get used to it, whore," he said. "There's a lot coming and we'll see if you die or not, won't we?"
"Oh let me go, stop it!" Sammy shrieked as his fingers slowly ran lower, between the lips of her pussy, pushing her panties into the swelling red opening. "Stop it!"
Jack grinned and very slowly ran his fingers even deeper. Then he grunted in surprise and grinned at Sammy.
"Fuck me! You're fucking wet, you little whore, you'll fuckin' wet!" He grinned at her and his cock bounced. "I've a good mind to rip these panties off you and fuck you right here."
"Stop it!" screamed Sammy, her whole body bathed in cold sweat. "Stop, I can't stand it! I can't!"
She dropped her head, tears running down her cheeks as his fingers played with her pussy opening.
"Oh well, it can wait," said Jack. "But I can't." Abruptly he stopped fingering Sammy and turned to where Amanda hung. "Let's get you down. I can deal with this cunt later."
He lowered the rope, and Amanda moaned in relief as the strain came off her arms and she dropped to the stone floor, cradling her sore tits. Slowly she caressed them, feeling the beaten flesh respond to the soothing touch of her fingers. Then she felt Jack put a collar around her neck, also with a long chain attached.
"Can't be too careful," he said and went to her ankles.
She moaned and pulled her knees under her, still cradling her crimson tits.
"Get up," said Jack.
Amanda struggled to her feet, almost losing one of her high-heels as she did so.
"Take off the dress," said Jack. "It's got in the way enough, tonight. Slowly."
Amanda couldn't pull the dress over her head because of the chain, so she allowed it to drop past her legs and onto the floor. She stepped out of it and let Jack take in her wonderful body. In many ways it was difficult to tell the sisters apart. Amanda's tits were a little smaller then Sammy's, and her ass was perhaps a little smaller and tighter too, but that was about all the difference anybody could see.
Amanda stood before him in nothing but her thin, pussy-hugging black panda and her black stockings. The only time she had let a man see her this way before wag when he was tied up and unable to get at her. Now the man staring at her could do as he liked.
"On your knees!" snapped Jack, his cock throbbing out from his loins like a gun about to explode. "I gotta get rid of this load before I can even think!"
