"I wanna ass-rape that bitch right now," declared Bob after they had returned from the lounge.

"More anal? And what about me?" Emma didn't want to miss out.

"I can ass-rape you anytime, sweet cheeks."

Emma giggled.

"We could do the same as we did with the little one earlier," Bob suggested.

"Nah, too lame," Emma countered. "I want to really fuck her up, and make the kids watch."

"It would be nice if she was still alive for the Masher. I don't know how much more she can take."

"Well there's only one way to find out. If she snuffs it, then we'll just have to mash up her dead body. The little ones can watch mummy pop while we rape them. It'll still be kinda fun."

"True enough," conceded Bob.

An evil grin spread across Emma's face. "Anyway I really wanna use that toy you made for me -- you know, the strap-on thingy."

"Tell you what, sugar bum, how about you ass-rape her with that thing while I make sweet love to your pretty, pretty booty? I'll be ass-raping her by proxy then."

"I love you so much," said Emma, planting a wet kiss on his lips.

The toy Emma was referring to was a terrifyingly clever invention of Bob's known as the Ripper. Essentially it was a double ended strap on, but the nasty end was a ten-inch long steel shaft. Arrayed along it, at half-inch intervals were counter-rotating rings of curved steel spikes, shaped for maximum damage.

The fact that each ring of blades whizzed round in an opposite direction to its neighbours meant that any orifice it was inserted into would rapidly be macerated into a bloody pulp. The whole unit was driven by a small but powerful motor contained within the shaft and powered by a rechargeable battery pack worn on a belt.

Once again fired with enthusiasm, they returned to the factory. Magda was shivering and mumbling in Polish. Bob untied the ropes and pushed her into the slops tray while Emma strapped herself into the Ripper.

She hit a button and watched, mesmerised as the teeth on her shiny new dick whirred around, then demonstrated it to Magda. "The gateway to your guts," she explained.

Magda, realising what was in store for her, promptly pissed herself in terror, leaving a yellow puddle in the tray.

Emma turned the Ripper off while she got into position. Then, she gently pushed the pointy end into Magda's asshole. Feeling the cold steel against her, Magda gasped, and tried to crawl forward.

Placing an arm around her neck, Emma lay down on top of her, and rode her like a wayward donkey as Magda gamely lurched forward. Now Bob joined the party, and climbed aboard his wife's sexy ass. The extra weight was too much for Magda, and she collapsed to the floor with a grunt, her chest squashed against the smooth steel.

Bob squirted a little lube, gently eased himself into Emma's sweet butt-hole and started to slowly fuck. "Ready when you are," he whispered into his wife's ear.

Emma flicked the switch and the blades whirred into life. Magda yelped as some of the spikes grazed against the soft skin of her inner thighs.

Emma pulled herself forward, and as she started to enter Magda's bum-hole, the screams abruptly rose in pitch like a fire engine. Magda tried to evade the infiltration of her body, squirming and bucking, her fingers clawing helplessly at the ground.

This only served to make things more stimulating for the happy couple, who were starting to get a rhythm going. Both started to push harder and deeper into their respective pits of delight.

The first spinning rings of destruction soon made Magda's sphincter history, and she tried kicking with her legs, her shrill screams becoming roars.

Her rectum was next on the menu, and soon a vile pool of blood, gore and shit was pooling under her. The pain was beyond anything imaginable, and she started to gasp in shock.

Still, Emma had only pushed a half of her length into her brutalised body, and decided to let Magda enjoy the full experience of mechanized buggery. Tightly grasping around Magda's neck, she pulled herself deep into her abdominal cavity.

The speed of the motor dropped as it worked to drive the twenty bladed rings, churning into her guts. Magda convulsed in a series of hoarse shrieks as her intestines were twisted, torn and sliced.

"Ohmigodohmigodohmigod," Emma chanted, as she started thrusting the silver member in and out. Each time the blades raggedly tore into fresh viscera, causing the whole device to shudder.

This impromptu vibrator was a novel delight for Emma, who could feel the blades jaggedly tearing into organs, muscle and fat, as well as every tremble of Magda's squirming paroxysms.

Needless to say, Emma's heaving, vibrating cheeks were an epic delight for Bob too. It was if the couple had melded into a exultant demon of bloody destruction.

Emma, Being stimulated so strongly in front and behind was now on a higher plane of bliss. She started orgasming, even though it had only been a couple of minutes since they had started. She could feel her own juices squelching against the length of smooth steel she had clenched in her snatch.

Reaching under Magda's body to pull herself deeper, Emma discovered the punctured breast and started kneading it joyously, working her fingers into the holes, squeezing the fatty tissue until they dripped with blood.

Leaving the whirring monster inside Magda's rapidly deteriorating belly, she started wiggling it from side to side, feeling it rip into new expanses of flesh. The pitch of the motor rose and fell with each sway, and Emma continued to be overwhelmed by wave after wave of orgasms. Shock had silenced Magda now, bar heaving, agonized gasps, bringing a delightful mix of grinding, squelching and wet chewing noises to the fore.

Bob, because of the relief he had enjoyed in the day's earlier exploits, still managed to contain himself, but was having the ride of his life. Never before had he seen his woman be so aroused, and as she thrust and vibrated below him, her tight asshole gripped and massaged his dick to the point where he could barely hold back.

Magda's innards were no more; her guts, bladder and uterus having been blended into a gooey slurry resembling chunky soup. Soon the blades bit through her belly muscles and fat from inside, intensifying the vibrations. It was too much for Bob, who finally shot his hot, sticky sauce into his wife's welcoming behind. Emma whooped and moaned, unable to contain her pleasure.

Then there was a shriek, not from Magda, but from hard steel scraping against steel. Emma had drilled right through her.

Emma pulled out, spraying all kinds of fluids in every direction. She turned the thing off, the shaft now coated with a thick layer of gore, and dripping with blood. She lay there for a minute, with Bob's still hard dick inside her, savouring the petite mort.

Bob heaved his frame from the exhausted pile of bodies, then Emma followed suit, unstrapping the ripper with trembling hands. The couple sat on the floor, utterly spent, panting and drenched in sweat. They looked in awe at the size of the bloody lake spreading out from under Magda, and reeled at the heady funk that now permeated the air.

"Damn, I forgot to take the lens cap off," sighed Bob, "I guess we'll have to start over."
