A store clerk was the first to happen upon the rubber doll. He had cleaned up the messy clothes outside of the changing room and stepped inside to check it didn't need cleaning too.
Michelle was waiting for him on the stool her shiny rubber legs spread her hands resting on her thighs and her lips forming a perfect "O" inviting his penis in to them.
The clerk felt a swelling in his pants. With a quick check outside he closed the curtains and disrobed; even when the women was rubber he still prefered to be naked during sex. The air cooled his swollen hot member as he slid it between the lips of the sex doll. They felt suprisingly moist and warm and he was soon pumping away. A further suprise came when the doll aided his quest for orgasm by sucking firmly on his hard penis.
Michelle revelled in the feeling of the Penis sliding into her, she wished the clerk had chosen one of her other holes but Cynthia assured her there would be other guys for that later. She felt the clerk spray his hot semen into her mouth. With a little effort she understood how to convert this substance, change it into liquid latex within her. She then did something suprising even to Cynthia. Michele gripped hard to his throbbing penis and squirted his semen, now transformed to latex, back into his penis.
The clerk was hypnotised by the strange sensation of something entering him. He could feel it stretching the shaft of his penis as it travelled down its length and into his body. He groaned as he felt an orgasmic feeling spreading from the area along with a strange warmth.
Michelle kept a link with the latex so it became like an incredibly thin tongue exploring the clerks body. She felt it following thin tubes and entering his testicles, from there she spread it out slowly working it into his blood stream filling his arteries and then his capilleries. There wasnt a cell in his body that wasn't connected with Michelle's latex and she understood it was only the flow of her latex that kept him alive; she'd already converted his blood.
The clerk could barely stand as he experienced the warmth fill his whole body. He felt like he was cumming in a continuous stream into the doll. He was blind with orgasm and only existed for the pleasure.
Still he could feel something further building up. He sensed he would soon reach a level of pleasure he couldn't comprehend. While he knew on some level that to feel it would be the end of him, he stil hungered for it.
Michelle and Cynthia could both feel the pleasure of the young clerk, they knew they would experience this exstatic moment with him. However once they were done the clerk would be no more and all that remains would be the Michelle/Cynthia doll.
They could see their future stretching out infront of them, an endless stream of victims consumed to fuel their liquid latex core. With each victim they would grow in power and each would gift them with that blissfull moment. The feeling that only came with the complete destruction of their prey. They could see this future and they liked it.
Michelle took a last moment to savour the feeling of potential, drawing out the clerks final seconds before she consumed him. Then she let his pleasure wash over her, as every cell in his body was converted at once to latex.
The shiny body of the clerk stood rigid before her. No living doll like herself, but more an extension of her being. The clerk was no more. All that rubber belonged to her; she only had to will it and it would join with her.
Cynthia was aghast at how quickly Michelle's power over the rubber had grown. She'd shared the pleasure felt at destroying the clerk and knew she'd been right to merge with her friend. Not wanting to disturb Michelle's enjoyment of the afterglow, it was her turn to take charge of the body.
Cynthia grew their rubbery clitoris till it became a great snakelike prehensile limb. She wrapped it round the rubber body of the clerk and forced it, feet first, into their waiting pussy. Slowly she began to digest him, the rubber turning liquid as it filled her body. Their belly and breasts stretched with the new latex but, still she kept consuming. Soon she had to relenquish their mouths firm grasp of his penis as she sucked him in further. By the time she was just sucking up the head she could no longer see it over their massively stretched belly.
Michelle came round at this point having quietly observed Cynthia's destruction of the rubberised clerk. She moved their arm to caress the taught rubber of their belly and breasts. She marvelled at how sensitive it was, how good it felt to touch. From below she could feel their clitoris stroking too. In its new form it slid over the surface of their belly and knew that it was under cynthia's control.
"Right!" Michelle said internally to Cyntia, "Playtime is over."
At this she placed a foot onto the pile of clothes that belonged to the clerk. The foot lost shape briefly and melted into them, when it reformed the clothes had been absorbed into their form too. Next she concentrated on condensing the latex within her, it compressed down till she regained their origional shape. The swirling potential of the super dense latex within felt good to both of them.
"My turn." Cynthia spoke exitedly in the same internal speak. "I have an idea to help us escape this place."
Cynthia took over control of the body briefly making it stand and face the mirror. Then with a little concentration she forced the latex of their body to change, it remember the shape of the boy they consumed and recreated it perfectly, right down to skin tone. It took very little effort to make her eyes appear to roll in their sockets and with that the illusion was complete. They were looking at the perfect reflection of the naked male clerk right down to the firm hard penis he had slid into their mouth.
Michelle added to the disguise, forcing the penis to become flacid and dorment. Then from out the pores of their body she let the liquid latex escape, covering them with a thin shiny layer that eventually formed into a perfect mimic of the boys clothing.
No one in the store suspected a thing ,as the store clerk calmly left the changing room and walked out the front door.
