Emily unleashes the demon

Without a word, Emily's father grabbed her by her voluptuous backside, spun her around, bent her over, and jammed his massive hell-cock inside her cunt. Emily just screamed with uncontrollable, frenzied lust, bouncing back recklessly on her dad's dick. At the same time, Amanda removed her coat and meandered over to Emily's sister, who was still wrapped in one of Carly's tentacles.

"Yes daddy, y-yes, fuck your daughter you perverted fucking beast! Use that f-fucking demon cock, make me cum! Fill me with your fucking s-seed, daddy, feed my m-Master with your tainted fucking cum!"

Carly watched the massive rod invade Emily with sick slurping sounds. It was thick, veiny, and monstrous, clearly demonic in nature. Carly squirmed thinking about what kinds of delicious evil a tool like that might be capable of. Although, she supposed that lust-fueled demon **** was a good way to start that list. Now that she saw it in action, she was strongly considering getting one for herself. Her ass hadn't gotten much attention since her transformation...

"Carly! Put the w-worm in mom - nah - now! I want to see her - tah - turn while daddy - eee - fucks me!"

Carly grinned, approaching Emily's mother. Though she was doing a good job of restraining herself, inside, she was a bubbling, horny mess. She was beginning to really appreciate Emily, and the wanton approach she took to being a demon and a worm ****. Emily had embraced evil and debauchery better than anyone so far, it seemed. She maybe lacked some finesse in how she got things done, but that certainly wasn't a flaw that would get her in trouble with Carly.

Carly had the worm that had been hidden in her coat, and as she neared Emily's mother, she saw tears in her eyes.

"Awww poor baby... Emily, she's crying!" Carly sneered.

"Mmmm don't w-worry mom, you'll - ha - love this! Don't - nff - fight it, either, it feels s-so much better when - yah - you let it in! You'll be thanking - mm - me once your new Master t-takes control! Fuck, harder daddy!"

Carly saw Amanda in the corner with Emily's sister. She had somehow managed to remove her clothes despite the tentacle holding the girl in place, and was currently toying with the girl, fondling her and whispering in her ear. Emily's sister's face held contempt, disgust, and defiance. She would be fun to break.

Carly began to work off Emily's mother's clothes from around the tentacle restraining her. It was annoying difficult, but she managed to get the squirming woman naked in good time.

"Just say when, Em."

"Oooooh fuck... He's close - hah - Carly, do it! I want him to - unhh - dump his fucking load in m-me when mom turns! - hunh - Put it in my fucking ass, daddy!"

Emily's father obeyed, immediately pulling out of his daughter's slime-covered cunt and shoving himself roughly into her asshole, his massive demonic cock stretching her to near-comical proportions. Emily screamed, a raw, inhuman sound. Her hair was disheveled and wild as her father fucked her tight asshole as mercilessly as he had been pounding her snatch. She looked up at Carly again, her glowing green eyes filled with lecherous glee.

"Fucking do it!" Emily screamed.

Carly shoved the worm against Emily's mother's pussy. In an instant it sprang to life, squealing as it writhed against her entrance, snaking its way inside of her. She could feels the woman struggling manically against the tentacle holding her, but it was too late. Once the worm was firmly inside, Carly retracted the tentacle and let Emily's mother fall to the floor. She lay there for a few seconds, seemingly ****. Then, like her daughter before her, coughed suddenly, spewing up a glob of black goo.

"No... I can't... no..." She whispered, seemingly to herself.

"Ahhhhhnnnnhhh FUCK YESSS!" Emily screamed.

Her dad roared, spewing his corrupted seed into his daughter, who was lost in ecstasy. Emily squealed and moaned as she bathed in her hellish orgasm, depraved laughter tinkling off her lips while her father continued to pump furiously into her ass as he doused her insides.

"I won't... No, no, get out of my HEAD!"

Emily's mother was fighting the worm. Carly knew she would lose eventually, but she felt like this was an anticlimax for a moment that Emily had been so looking forward to. As Emily's mother weakly propped herself up on all fours, Carly moved behind her. The demon inside her roared to life when she summoned her central tentacle out of her dripping cunt, and shot it straight into Emily's mother's ass. She felt it snake its way through half her body, as the woman screamed below her in shocked arousal. Carly used the strength of her tentacle to lift the woman, carrying her over where her husband and daughter were still violently rutting, even after their monstrous climax. Emily's mom's new worm Master shot out of her pussy, so Carly positioned the woman's freshly-corrupted cunt directly in front of her daughter. Emily's eyes lit up with debased elation, and she quickly sucked the appendage into her mouth, now being spitroasted by her demonic parents.

Carly reveled in finally being able to let loose and fuck something with her tentacle. The thrill of corrupting another innocent soul grew to a fever pitch as Emily's mother's moans sounded more and more like ecstasy. It wasn't long before she was screaming demeaning obscenities at her perverted daughter, her new demonic nature quickly forming and manifesting itself as she fucked her daughter's mouth with the slimy, foot-long worm slithering in and out of her cunt. Emily looked to be in pure rapture, her father reaming her ass, and her mother's worm violently assaulting her throat. There was a puddle on the floor as cum and slime mixed, dripping in thick gobs from Emily's battered cunt and down her thighs.

Carly looked back over to Amanda, watching her toy lazily with Emily's sister's body, trailing her fingers lightly, teasingly, over her nipples, clit, lips. She could only imagine the kinds of things that Amanda must be whispering in her ear; whatever it was, she knew that she would probably never have been able to resist it, knowing Amanda's boundless deviance. Emily's sister still looked defiant, but the situation had clearly gotten to her. She had watched both her parents convert, and watched her sister fuck both of them like a deranged whore, all while having her body expertly manipulated by a demon of lust. Carly hoped that the **** of this delicious little morsel would last a little longer than just the car ride home.

After another round of reprobate orgasms, the girls had had their fill, extricating themselves (albeit reluctantly) from Emily's parents. Emily was having a hard time letting go of her father, pressed against him, looking up with puppy-dog eyes and stroking his throbbing cock as the girls prepared to leave.

"Bye daddy... if you ever get tired of mom and need your baby girl's mouth, or ass, or cunt, just let me know. And I'll let you know when we've broken Rain! We'll be sure to have her begging for you guys! She'll be the best little demon daughter you ever had."

"Hmhm, well it'd be hard to outdo you after that performance. Your Master is lucky to have such a spunky little whore for a ****," Emily's dad chuckled.

"You girls stay safe out there, and good luck! And thank you for sharing your babies with us, Amanda!" Emily's mom chimed in. Amanda gave a sweet smile and waved back.

"We will!" Emily called back. "Oh, and call the school, tell them Grandma died or something. Rain and I are taking the week off for some bonding!" Emily cackled.
