Kasia felt a creeping dread overtake her and she felt cold and dizzy.

Bob smiled, "Good choice. Try not to actually snuff her though, I want a taste of that too!" Then he laughed. "Sloppy seconds!"

"But on the other hand, the little one is noisier," Emma said. "I can't imagine how yummily she'll scream. It's so hard to decide!"

Bob sighed.

"Don't be like that, Bob! It's your own fault for bringing so many!"

"But I..." Bob started.

"Okay, okay. I'll do the brown one then. Final decision. Maybe we can do the head-sawing thing with miss cutie-pie over there later."

The casual banter horrified Kasia, but she was mostly relieved. At least she would be spared the knife dildo. Even 'head-sawing' sounded better. She looked over at her sister with pity, but didn't feel as bad about it as she expected.

A few minutes later, everything was in place. The little one had her ankles bound and was placed in the tray. She didn't seem to have much energy now, perhaps the earlier damage to her mind and body was taking its toll.

Kasia was sullen but seemed more stoic. With just a word from Bob, she cooperatively lay down on the wet steel, next to her sister.

"Ready to enjoy the show?" teased Emma.

"I won't look," Kasia sulked.

"You can listen though. You can't put your hands over your ears if they are tied up can you?" It was clear Emma was enjoying tormenting the girl.

But as she was being so cooperative, Bob elected not to tie her up anyway. He could easily dominate her if she got unruly. Besides, he liked it when they tried to struggle and escape. Giving them a little hope added to the thrill.

Despite her ankles being bound, Maisie was trying to crawl out of the pit. Emma grabbed her by the arm and flipped her onto her back, head towards the machine.

Bob stood over Kasia and flashed her a big, warm smile, that made her feel strangely weak. Her heart was pounding against her ribcage and she had butterflies as he straddled her.

He pulled out his knife, and Kasia found her throat had closed up in fear and she could hardly speak. "Quick!" was all she could manage.

Bob put the blade against her throat. "No funny stuff, okay?" Kasia nodded, wide eyed. She thought she was going to pee. Bob sheathed the knife and strapped it tightly. He didn't want this little bitch grabbing it while he was doing the business.

Then he slid a big hand under her white cotton top and gently squeezed her exquisite, pert right breast, dragging his thumb across her nipple. Kasia held her breath and just stared at him, trembling a little.

"Such a shame," he said cryptically to no-one in particular.

Next, he pulled her PJ bottoms down to her knees. Those slim, toned legs set his pulse racing, and he caressed a thigh as he moved his hand north towards Kasia's flower. 'Just coming into bloom,' he thought. He squirted a little lube and eased a couple of fingers inside. After massaging her a little, he pulled out his dick and gently pushed in.

'Shit just got real,' Kasia thought, and gasped involuntarily. It was her first time, and it was pretty damn uncomfortable. But still there was a tingle of naughty pleasure that caught her off-guard.

"I think we're all set," Bob said, and watched as Emma, with a cruel grin, responded by slowly pushing her steel blade through Maisie's soft cotton PJ bottoms, straight into her immature foo. A near-ultrasonic girly scream echoed around the factory.

"See? That's what I'm talking about!" laughed Emma.

"Fuck!" Kasia yelped as she watched the horror of the knife enter her sister, then turned her head away. It was clear that Emma was going to rape Maisie to death and God only knew what kind of sick shit Bob was going to inflict on her own body. She just hoped it would be over with soon, and that her demise would take her away from this nightmare forever.
