Slimy adventure

What was left of Cynthia's mind ...was not very much. Her new gooey body moved around the building aimlessly for a while as she tried to gather her wits and learn what her new form could do. After squeezing herself underneath a door she decided to explore just how far she could extend herself and how tiny holes she could take advantage of. A bit of fumbling later she opened a faucet ...and **** herself into it against the flow. A more rational mind might have tested this ability in a safer way, the being that used to be Cynthia simply enjoyed the ride until she found an exit from the waterline.

June, a young woman of 18 years had been showering when the water suddenly stopped. She and her sister July (yeah, silly names but parents often did that with identical twins) had been taking a refuge at their father's home. They arrived late and though their father already was asleep, the young women wanted to freshen up before hitting the bed. The day had been so stressful, but now at least they were safe with daddy. If only the water worked.

"Sis! There's something wrong with the shower!" June exclaimed. Her sister had been waiting outside but now came to the bathroom.

July opened a faucet. "The water works just fine, it has to be the showerhead that is somehow blocked."

The twins were of athletic build and natural blondes. If it wasn't for their rather small tits and butts, there would have been lines of horny young men trying to conquer them. As it was they had to turn down more than a few guys. Mainly the creeps who wanted a "twin experience." Right now the only differences between them were that July was fully clothed and June covered in shampoo. As they tinkered with the shower and tried to tap it to see if the clog would come dislodged, they noticed that the pipes leading to the showerhead began to bulge. Before either could take a step back, blue goop began to rain over them.

"HAck! Ghah! Fffuck what is this?!" July complained as droplets of the slimy substance landed on her face and she nearly choked on it.

June had been staring at the showerhead and she could not even scream as the slime was covering her mouth. More and more of the substance came. Suddenly July realized that the slime was moving on its own. She tried to swipe it off of herself but instead the slime got stuck on her hands and then hardened like handcuffs on her.

The twins were soon writhing on the floor of the shower. They didn't even notice that the water was working again, being covered and groped(?) by the slime had the preoccupied. Just as June felt like her lungs were about to explode, the slime retracted enough from her nose to let her breathe. And then it began to enter her other holes. June was now writhing from the strange pleasure of tentacles exploring her cunt and ass. She wasn't wet, but the tentacles were so moist and slimy that it practically counted as lube and June was shocked to realize that this strange **** felt good. July meanwhile tried to scream though her mouth was gagged by the slime. Her clothes were melting off of her. The fact that the slime didn't seem to harm her skin was a surprise. This ...thing... was clearly sentient and seeing the tentacles that were **** her sister, July was not surprised to see similar tentacles grow out of the blue slime that had her restrained on the floor.

If the **** of their bodies was a shock, it was nothing compared to what happened when the slimy substance began to crawl into their ear canals and breach their brains.

"Oooooh, identical twins. I've never had those before." Cynthia's voice boomed inside their heads. "Let's see what we've got here..."

Cynthia the slime girl began to explore the memories and personalities of her victims. As she did so, the girls noticed that they could feel and sense each other. Somehow the slime was connecting them to each other.

"Sis?! Is that you?!" "What's going on?! I'm scared!"

Cynthia's giggles echoed in their minds. "We don't need all this clutter, I'm just going to clean things up a bit." Cynthia told them. The girls could only scream and beg for mercy as their brains were getting rewired and rewritten. Soon they realized that though they felt everything that was happening to them ...felt it doubly even as they could feel each other's senses as well... they could not control their bodies. They were helpless voyeurs as Cynthia puppeteered them.

"Time to try out some twincest" x2 the naked and wet twins said robotically. Cynthia had always liked to make her puppets kiss when she was a kid. Now she could do that with these teens. It felt good. As did the tentacles that were still fucking their holes. The feedback loop of pleasure threatened to break the minds of the young women.

Next Cynthia made them do 69 on the floor. Powerless to stop her the twins could only take the flood of pleasure flowing into them. "I- I can't..." "S-siiis! FFFuck your tongue feels -Ah- so good!"

Cynthia could still feel some hesitation inside her victims. That was silly, why didn't they just enjoy the ride? "This bit is totally unnecessary." Cynthia stated as she began to remove the parts of their brains that gave them such issues. They didn't need taboos or conscience to cloud their joyful incestous experimentation. She decided that it wasn't fair to just take from them, so she gave them some upgrades as well. Their tits and asses grew much bigger. Lips filled up to perfect cocksucker perfection. They had been feeling pleasure before but now all their senses seemed amplified. It was too much for them. Their minds broke. All that was left of the twins were bimbo's that lived to fuck and suck anyone they saw but especially each other.

As fun as it was to toy with the girls. Cynthia was getting hungry. And it wouldn't do for her to feast on the twins. Their father though...

A moment ago, this thought would have filled the girls with panic and made them try to fight back. Now as their master made them enter their father's bedroom and crawl under his blanket. He woke up with two mouths working on his cock.

"Hi daddy!" June greeted him happily, with a voice dripping with sexual needs, a voice her father had never heard from her before.

"We got a little hungry... Would you have a late night snack for us?" July continued.

Daddy made no resistance or even tried to reject them. Cynthia suspected he had had dreams of something like this before. She was more than happy to have him live those out.

Another toy let Cynthia try out all kinds of things. The twins making out and grinding against each other while daddy took turns fucking their holes. Twins doing 69 as daddy came into their cunts and watched them suck each other clean. He had a lot of energy and that was good.

Finally when July was riding daddy's face as June rode his cock, Cynthia noticed that the man was slowing down. Reaching his limit. Playtime was over then. June and July felt weird. Weirder than before. Their mind connection suddenly broke. The blue slime began to pour out of them and flow down over their father.

Daddy took a while to notice the slime and by then it was too late. He struggled against it but all he accomplished was to knock his daughters off of himself.

June and July were confused. Thinking was so hard. Something was wrong with daddy. They couldn't quite understand what. The blue slime made them feel so good, why didn't daddy like it? There was one bit of the equation that they could understand. Daddy's cock was still rock hard. The twins crawled up to him, to try and help daddy feel better. July took his cock into her mouth as deep as she could as June began to suck and lick his balls. Daddy was straining and trying to fight off the slime that covered his entire head and began to plunge down his throat, but all through this, his daughter's worshipped his cock.

Cynthia reached deep inside the man, looking for the nourishment she needed. She found his soul. She allowed the man one last treat before killing him and made him cum his brains out. July happily took daddy's final cumload into her mouth as Cynthia tore out his soul and absorbed it. Digested it.

As Cynthia retreated from the corpse of the man, she left it behind completely drained of all fluids. She took most of them but his cum had been offered to his twin daughters. Cynthia watched as the bimbo sluts June and July took turns pouring the massive amount of cum out of their own mouth, into the waiting mouth of the other twin. Cynthia was vaguely aware that the twins hadn't even been infected by the Lilith strain yet. They were fully humans though their minds had been broken and corrupted and bodies improved. They could make for great infiltrators. Not that Cynthia had the brains to make use of those.
