Izzy groaned as the movement caused the dildo and plug inside her ass to move. At the sound the brute carrying her reached back and spanked three times, his hard touch making her squirm as the toys pushed deeper, causing the dildo to push out against her belly. The machine continued to move, lengthening and expanding inside her. She was unable to stay still as her cunt dripped. Telling the other man something in a foreign language they both laughed, then the one carrying her moved her to a better angle so his friend could reach her tits. He pulled hard on her nipples, stretching them out as well as digging his nails into the hard nubs. A bolt of pain went straight to her cunt and she leaked even more wetness, much to the mens amusement. Another hard pinch and more juice flowed.

As the men threw her in the back of a blacked out vehicle her cunt continued to flood. They joined her, spoke into a radio, and the vehicle jerked to life. As it drove away all of Izzy's thoughts were of cock and how she needed more. And it was a NEED not a mere want. It was overwhelming, beyond bearing. She HAD to get filled with cock.

The man cut the rope holding her cunt open then removed the plug. As he pulled out his already hard cock she groaned, seeing it was the thickest one yet and the longest. Her now empty cunt spasmed and dripped continuously, puddling on the floor but the man simply sat there, watching her cunt. Izzy didn't care, she needed that cock like she needed to breathe. His friend suddenly flipped her onto all fours, ass up in the air, then a cock rammed in her cunt so hard she convulsed on it. The only reason she stayed in position was the other man's equally huge cock going down her throat. His precum coated her throat as his balls bounced on her chin each time the other man thrust. There was still something missing. Her ass needed cock despite the bliss of the toys inside

The man was brutal as her cunt stretched around him. His cock felt even bigger than it looked as he used her. He reached down and yanked the plug out of her ass whilst never breaking rhythm. The machine extruded itself as well, reforming to its original shape. As a huge fist started reaming her ass Izzy began to cum hard, her juices splashing onto the already wet floor of the van. A near constant flood soaked the man's cock as the drugs continued to change her. He fisted himself then slid back inside her, causing a new and blissful stretch as he wanked himself in her hole. Her soaked cunt squelched even louder as another fist joined the other one already in her ass. The machine moved under her and reformed with mouth's and hand-like appendages. It suctioned onto her nipples, pulling back to stretch them out whilst the hands bruised as they roughly squeezed and pinched and pulled the juicy globes. Her cunt clenched hard as the pain increased and another flood of juices ran down her thighs.

Between the fisting her as was getting, the huge cocks using her other holes and the machine on her tits the only thing Izzy knew was that she was born for this, to be stretched and filled, used however men wished

She screamed as the fists in her ass drove deeper and she bucked, begging for more. Blood mixed with cum as the man drove in up to his elbow, again and again as he repeatedly rammed, forcing himself deeper. Her strongest orgasm so far had her spasming for minutes whilst the brutality continued. Finally the cock in her mouth poured hot liqid straight down her throat as the one in her cunt also flooded her. This one's unbelievably hot load caused her to cum again though she was unaware of its true purpose. Her newly reshaped cunt was healed, as was her now more flexible throat. More flooded her ass, burning her as it healed her altered hole and internal organs. She continued to cream and spasm as the men and machine continued with their work.

Two large fists pushed into her cunt, synchronising their movements for maximum pain and stretch. As a mouth clamped on her clit she gushed and the fists expanded inside her again. A third appendage forced its way inside and thickened with each movement of the fists, stretching and stretching her drenched hole. A momentary pause and another entered her ass, forcing the man's fists to spread apart as it expanded. Her ass tore and rehealed every few seconds as the expansion continued. The third appendage finally withdrew, only to be replaced by an enormous cock that thrust ever deeper. The machine contracted again, leaving all Izzy's holes for the men to use for a while.

Izzy faded out while the fists and cocks continued to use her holes. Finally the one filling her abused cunt pulled back as the machine took his place. It expanded again and again, stretching her more and more, far beyond the size of any human cock. The fact she would never again feel a tiny human cock in any hole made this irrelevant. The back of the machine transformed and took its own place in her ass. It continued to expand and lengthen till it reached the limit of what would repair instantly. Her body appeared bloated, deformed from the size of the appendages filling her holes as she continued to leak with need, writhing and moaning, clenching onto the toys as her cum flooded them.

The alterations to her body kept her continuously soaked cunt and juicy ass always ready for use, holes primed and desperate for anyone and anything that would momentarily ease the need.

She was going to be very popular (and valuable) when she was fully trained for them... as long as she survived the final stage
