Kasia was oblivious. "Yeah, that's pretty scary!" she giggled as she swung her legs over the edge and hopped down.

Bob said nothing, his eyes distant, his thumb still trembling above the button.

"Bob, you okay?"

"Oh, yeah. Sure. I was miles away."

He snapped out of his reverie, and proceeded to show her the simple controls. The belt and roller could turn either way and the roller's height above the conveyor was adjustable by push buttons.

Then they stripped off Maisie's bloody rags, and dragged the corpse over to the machine. One could almost imagine that little brown body still had life, were it not for the jagged hole torn between its legs.

They arranged the corpse on the belt face down, arms stretched out ahead, superman style, and twisted her limp head to face them so Kasia could watch her face as it crushed.

"I'm gonna fuck you again," Bob stated matter-of-factly. "We'll do it doggy style so we can both see."

Kasia sighed happily. "Well I can't really stop you."

Bob found an old wooden packing crate of the right size, and Kasia stretched across it, facing the conveyor, her knees almost touching the floor tiles.

Bob pulled down Kasia's PJ bottoms and started prodding his dick into her wetness.

"Oh-oh-oh," Kasia exclaimed. She was still tender from her earlier pounding, but it felt yummy all the same.

Then Bob grabbed a fistful of her hair in one hand, and a breast in the other. Kasia liked that. He thrust his member in, balls deep. "Yahhh!" cried Kasia, and tears sprang into her eyes. Bob kept his dick deep inside her panting body for a few seconds, and he could feel her heart pounding. He pressed the remote control into Kasia's hand. "I'll let you work it."

She clicked button to start, and with rumble and slight jolt that jiggled Maisie's corpse the belt started to move at its lowest speed, maybe just a quarter of an inch every second.

Kasia still couldn't believe any of this was really happening, and felt her cheeks flush with shame. But she found the anticipation exhilarating and there was no going back now. She pushed back against Bob and gave her butt a little wiggle just to tease him.

Bob realized he was taking quite a shine to this girl, but soon put it out his mind. He couldn't allow himself to get too attached. He tried to distract himself by imagining Kasia was the one getting squished as he fucked her. Maybe he'd figure out a way to do that for real later.

Suddenly he heard a noise behind him, and discovered that they had been joined by Emma, who had been awoken by the sound of the machine starting.

She was watching, fascinated, and rubbing herself through her onesie. A dark sheen had appeared at her crotch. "I couldn't miss this," she explained, licking her lips. "Maybe we can try it on a juicy, live one tomorrow."

Kasia froze for a moment. Her little fantasy minutes earlier suddenly didn't seem so appealing, but any such concerns were driven from her mind by the unfolding events.

Maisie's little hands were now approaching the roller, which Kasia had set to run just an inch above the conveyor, thinking it would be super-duper to watch her sister's corpse be squished into an inch-thick meat-feast pizza.

The three of them looked on with delighted horror, as Maisie's fingertips reached the roller, and through the inch gap.

Then finally the roller made first contact. There wasn't really any discernible noise as her hands were gently pressed into the gap, but then there was a little pop as some of the numerous wrist bones were displaced, and then a soft crunch.

Suddenly Maisie's dead eyes sprang wide open. Bob thought it must be some kind of nervous reaction, but then an unholy choking sound issued from her. She coughed up some fluids and took a big gasp of air.
