"Are you sure this is ok Twilight?" 

"Of course Spike! I don't mind a bit, and if you like I can leave you alone with this for as long as you want."

The little dragon smiled as they stood next to a massiive stainless steel machine that Twilight had built with the help of a unicorn from Canterlot. It was a request from Spike to make something powerful enough to crush gems. He made the excuse that he wanted to try gem powder in a special food at some point, but he had far darker intentions.

"I'd... like that, for now at least. Thanks~" he'd bounce on the heels of his feet as he spoke. Twilight nodded and happily obliged the respect of his privacy. 

"Just make sure you use the hard hat... and please be careful with yourself. If you need me just yell." she'd kindly remind before walking out of the door.

With that he was left to his own devices.

Grinning wickedly he walked towards a corner of a room to a visibly moving sac. "Well well WELL... looks like some critters are gonna get to see what a big bad machine can do~"

The various forest life inside were panic stricken, trying to free themselves from the tight confines of the old sac. Spike casually dragged it behind him with both hands as they battered against his back every so often. 

Smiling, Spike pressed the big red button to start up the machine that stretched from one side of the room to the other, taking up both the height and length of the room save a few small spaces. It sputtered like a large truck and thrummed from the various parts inside. Warning labels, statements and symbols riddled it from end to end.

The little dragon walked up a few steps on a step lader next to a conveyor that led upwards to drop its load into a large dark opening below. Spike was able to see the opening but couldn't make out what awaited inside. 

Casually he began unwrapping the bag and tipped it over onto the last slits of the conveyor before they disappeared. Two rabbits and a fox were the first critters in his sac to come out. With such little time to react they could only scramble to the side of the conveyor that led them upwards for a short moment. 

"No, no stay there!" Spike grumbled, seeing the fear in their eyes as they all fell into the abyss with a metallic thunk. 

"Mmh... get em big guy..." moaned the little lizard as he tied the bag again and got off the step lader quickly to make his way over to the jutting piece of metal that they fell into. 

He stood there in awe and twisted arousal, his pink rod 5 inches in length while his balls were nearly touching the ground. He gently gripped his rod and began to masturbate to the thought of the event in general.

*Chwee, Choof, Chwee, Choof, Chwee, Choof* Was all he heard, a soft whirr with some light clanking, along with the echoing howls and squeaking screams from those he put inside. His only clue to what was happening to them was a warning label that showed a pony being put through some sort of rollers.

"I wonder what that feels like..." he'd say aloud to himself, stepping close to the smooth metal as he kissed it and caressed it with a free hand. He could feel the parts inside moving, at least on the "choof." The metal gave a slight punch, a shockwave of sorts every time the rhythmic sound happened.

His eyes caught a glimpse of movement to his left. He ran over to the second conveyor to behold the mess that the critters were. They were definitely alive but mangled and contorted. The fox especially had both legs turned around, paws completely turned backwards and it's neck was stuck to the side.

Spike panted and oggled the damage with fascination and interest. He was amazed what one part of the machine did to them, making him all the more curious on what they exactly went through; what kind of parts did such a thing. 

The little dragon couldn't handle the excitement anymore. He began stroking his rod harder and faster; his nuts beginning to tense.

"Ahhhh~" he'd huff, arching back as he fired his potent seed at the conveyor. The first wad splattered onto the fox's face with force while the rest messily coated it and the rabbits. The conveyor also had a nice opaque coating of thick slime.

As suddenly as his orgasm finished, a loud hiss was heard. Rotating wheels, similar to a steam train's piston, began to turn. Three large pistons began pounding down in rhythm while the conveyor kept moving the battered creatures down at a slow pace. *Boom boom boom tshhhhh... Boom boom boom tshhhhh... Boom boom boom tshhhhh...* They were all smashed by the heavy metal cylinders.

Spike's eyes were wide and his mouth hung open; continuing to stroke his still erect meat at the sight. He couldn't help but step forward, inches from the conveyor as he looked up at the pistons rising to the ceiling and then dropping down; able to feel the air blast past him when they dropped down.

A rabbit's paw hung off of the conveyor as it laid on its belly. He could see with each pound that it tensed heavily and twitched violently from pain. Spike cooed and gave the paw a tender touch, rubbing it between his claws on the way down the conveor belt. "So... so lucky..."

Once they finally reached the end and entered the dark tunnel on the other side they were almost completely flattened. Their skin was bruised and purple, especially around the back, mid section and head; all of them slick from bits of blood and dragon sperm.

A yellow warning light came on above the tunnel once the fox had entered; the bunnies following right behind. This was the loudest part of the entire machine. All Spike heard from the critters now was a quick, sharp yelp.

This part of the machine began to vibrate violently, distorting it's image to Spike's widened eyes as it blurred. He had to rub them a moment to make sure he wasn't losing his vision. His curiosity was definitely at play now.

He walked over and saw a warning label on a battery pack to the side that seemed to power this part. It showed the cylindrical tube with vibrating lines all around. It also showed arrows pointing in other directions around the tube. The pony inside looked like it turned into a puddle.

Spike couldn't quite understand how this one was working, or what it did exactly.

Suddenly, the tubing did begin to rotate like a cement mixer. The harsh buzzing of vibrations continued while Spike watched, slowing his masturbation down as he was still clueless on what this was doing to the creatures. He patiently waited while the machine separated the broken down flesh, muscle and organs appart; spinning and vibrating them into a fine liquid with almost every part.

Minutes later the rotations and vibrations stopped suddenly. A little "ding" was heard with an arrow on a screen near the battery pack that motioned him to the back of the machine.

When he made his way there, a see-through sac attatched to a spigot was seen. It was already being filled as it swelled with blood and chunks of unknown parts from the unfortunate critters. Spike was ecstatic. He ran over and gawked at it filling up; putting a hand under the sac to cup it while he savored the graduating weight.

He felt another intense climax coming on. Quickly he turned the spigot to stop the flow, took the balloon off, and put the head of his cock inside; just in time to cum. He leaned against the metal while he held the sac in one hand and his cock in the other, mixing his thick seed with the dark red juices of the once fluffy creatures.

Once his powerful climax finished he took a moment to pant and reflect on just what this device did; loving every second of recolection. Slowly he pulled his member out and tied the end of the sac, gawking a moment at the chunks and his seed floating around inside. 

Now it was time to repeat it all again; this time with all the critters he left in the sac.
