One of Jack's fingers slid into Amanda's shitter.
"Ohhhhh, fuck me!" she moaned, heaving her ass back at him. "Put another one up, ohhh, please!"
"You wimp, you sold out!" Sammy yelled. She pulled herself as far up as the bonds would let her, staring at her sister about to get double fucked.
Jack rammed another finger into Amanda's ass and listened to her moan. Then he pulled out and creamed his cock, while Amanda and Ken fucked slowly, their mouths locked together in a passionate embrace.
"Ready?" Jack asked.
As the tip of his cock thrust at her brown shit hole, she lunged back, moaning, capturing the head of his prick. Her mouth clung to Ken's neck as she kissed and licked at him, heaving her tits at his chest.
"Shove it up me!" she yelled. "I want both of them, come on!"
Her hips beat at Jack as he rammed his cock at her ass, penetrating more than three inches in the first thrust.
Amanda screamed with uncontrolled depravity, her orgasm exploding over her as the double-fuck rammed her pussy-walls apart, and the thin line of flesh between her two fuck-holes throbbed and heaved at the double invasion. "Fuck me, oh fuck me!" she moaned as the two men slammed their cocks into her, matching their thrusts to the pulse of her climaxing body. Her fuck-holes sucked at their cocks, driving both of them into rising surges of lust.
"Jesus Christ!" roared Jack. "The little cunt's gonna make me shoot!"
"Ohhhhh, shoot up me, shoot cum all over me! I wanna be fucked, ohhh, I wanna be fucked!"
Her body rolled to the beat of the lust that had been let loose in her. Exploding bursts of come drew endless screams from her as her body moved and performed for the men with primeval lust.
"Fuck me, whip me, do what you like, but make me come!" she moaned, her mouth wide open, seeming to beg for a cock to shoot over her lips. "Oooohhhhh yesss, yesss! Ham your cocks up me, fuck me, beat me, make me come!"
Jack's cock swelled as the jism surged out of his balls.
"You bitch!" he roared. "You fuckin' little whore! I'm coming, I'm gonna shoot!"
Amanda looked down at Ken as he lay under her, his cock slamming into her cunt. "Ohhhh please, come now! I want you to come together, I'll get you hard again. But come!"
Ken looked at the beautiful blonde spasming above him, her climaxes making her cunt close around his cock like the most demanding mouth in the world. She was sucking the cum from him.
"You bitch," he whispered, "you know you can make me come any time you want to. I'm coming now, you wonderful whore, you bitch!"
He ran his hands inside the neck of her slip, breaking two of the buttons off. His fingers closed on her nipples, twisting them, as Amanda screamed and thrust her tits at him, shrieking in utter ecstasy as the final bursts of climax erupted like a volcano inside her.
Hot jism burst out of Jack's cock into Amanda's ass. He roared like a bull, thrusting his cock deeper and harder into her sucking shithole. Thick ropes of cum trickled out of Amanda's ass as his cock emptied its load, and she screamed with the force of the fucking. Her ass-muscles clamped around his cock, sucking the last drop of jism out of it.
Then Ken's cock squirted, his cum rushing into Amanda's cunt as she held her tits for him, moaning in lust as he rolled her nipples harder and harder with each shot of jism.
"Ohhhhhh!" Amanda screamed. "Ohhhhh yes! Ohhhhh fuck me, hurt me, hurt me, yes!"
With a final shriek of release, she sank down over Ken as he gave her nipples a final twist and the last of his cum poured out.
"Make me feel like that and I'll do anything for you!" she whispered to Ken.
Ken grinned.
Jack moaned and pulled his cock out of Amanda's ass.
Sammy pulled herself up on the bed and yelled at her sister.
"You whore! Traitor! You gave in to a pair of fuckin' men! You stupid slut!"
Amanda raised her head and grinned at her sister. "This ain't nothin' kid. You wait till later."
CHAPTER TEN
The next two days were torture for Sammy. She was left tied to the bed, alone for most of the time. She was allowed occasionally to go to the bathroom, and several times Amanda would come in with one or both of the men and fuck them in front of her. Amanda's submission to the two, brutes drove Sammy crazy, particularly as Amanda seemed to be getting off on it so much.
Saturday passed into Sunday, and Sammy wondered if she would ever get out of the dreadful place. Suddenly, without warning, Amanda came back in, but with a tall woman whose dark hair ran halfway down her back.
Sammy shot up on the bed, shaking with fear. The dark-haired woman was dressed in thigh length black boots and a black corset that pinched her waist into an hourglass figure. She carried a whip with a singe long tail, and wore a small black cap pulled down over her eyes. She stood in the center of the room, twisting one of her spiked heels into the carpet, and looked at Sammy.
"This the little shit?"
"Yes, Miss," said Amanda. She wore purple stockings with high heels, a tiny pair of matching panties and a purple waist-cincher that pushed her tits up and only covered the lower half of them.
"Untie her!" snapped the woman. "My name's June. Either you obey me or you'll be in trouble."
Sammy stood up and glared at June. She rubbed her wrists, getting the circulation back. In her vanity mirror, she saw that most of her crimson bruises had faded to a dim red glow. Her ass and tits stuck out as if they were ready for more fucking.
"Into the bathroom!" snapped June.
For a moment Sammy was going to refuse, but she had to take a piss, and it would be stupid to make things even worse for herself. She followed Amanda to the bathroom, June pacing behind them, her heels thumping on the floor.
"Into the shower!" June snapped after Sammy had relieved herself.
Again, a shower was something Sammy desperately wanted, so she got in and washed herself from head to toe. She got out and dried her hair and body.
"Back to the bedroom!"
Sammy walked back. As they passed across the end of the passage, she heard people entering, but she couldn't make out how many, or if they were men or women.
"Put those on," June said.
Sammy looked at her for a few moments. It was now clear that she was going to be the main attraction at some new vile and depraved party the men were having. They were going to whip her, rape her and try and get her to beg for her humiliation.
Slowly she slid the stockings on. She would show them. All she had to do was refuse do to what they wanted. Make them rape her – Jack would hate that.
After the stockings there was only the suspender belt, panties and a tiny bra that showed half her tits. She slid the shoes on and looked at June with great contempt.
"Try me, bitch!" she snarled. "Try to make me do what you want!"
"Oh, don't talk like that, Sammy!" Amanda cried. "Do what they say, it'll be…"
"Shut up, whore!" snarled Sammy. "You give in."
June smiled and flicked the whip through the air, only just missing Sammy's tits. "You'll learn. Now get downstairs!"
Sammy found that her breathing was becoming unsteady as she went down the steps to the dungeon. Once inside, she gasped. There were three more men and two women there. They were partly in shadow, so she couldn't see too much of their faces. In the center of the room stood Jack and Ken, waiting in their robes.
"Ah hah!" said Ken. "Here we have the main attraction."
There was a round of applause for Sammy, and her heart beat unsteadily.
"Okay folks," Ken said with a grin. "Here we have the classic case of the good sister and the bad sister. We will demonstrate the good sister first and then make the bad sister into a good one. Won't we, honey?"
