Joins the orgy

"Just get away from me, Emily. Go do whatever you need to do, just do it away from me."

"That's hurtful sis. But make sure to watch us, I wanna show you what it's like to be one of us! You'll come around!"

With that, Emily scampered off to the bed where her new sisters were fucking. The scene was exquisite. Carly was lying on top of her sister, biting and kissing at her neck and tits, her massive tentacle working in and out of both their pussies, making the most beautiful squishing noises. Becca was completely full, a cartoonish caricature of herself. Her flesh bulged and shifted as Carly's tentacle abused her insides, using Becca's willing form to masturbate itself.

Amanda had her pussy pressed firmly against Becca's mouth, as she shared the thick tentacle that protruded from her throat. It jammed itself roughly inside Amanda's leaking cunt, slime and cum coating Becca's face. Amanda was cooing and moaning, while Jenny was her usual raging beast, plowing Amanda's asshole with vigor. Her hands groped and squeezed Amanda's body abusively, claiming the corrupted broodmother as her property.

Emily noticed that Carly didn't have anything in her ass. Her Master stirred inside her, slithering out of her dripping pussy. Emily swam in the sensation, and moved to go fuck Carly as hard as she could.

"Good... you humans have taken to this better than we could have dreamed."

"Mmm Master you've been quiet for some time. Glad you approve! Did you like what I did to my daddy?"

"Your corruption of your family was very well executed. It is good that you continue to debase yourself like this. The more you and your brood give in to this, the more tainted your soul becomes. You are opening yourselves up to power you can't even fathom, and that is good."

"Then I guess we should go fill Carly's poor asshole, shouldn't we?"

"You are correct. Go, please your mistress."

Emily wasn't quite sure why he called Carly 'mistress', though she did seem to be the de-facto leader of the group. She was also incredibly excited by the prospect of 'unfathomable power'. She would have to tell the girls what her Master had said once they had sated each other.

Emily hopped over to the bed where her demonic sisters were indulging themselves in each other. She jumped up behind Carly and shoved her cunt against Carly's tight, round bottom, sighing with lust as her worm Master slithered out of her, and into Carly. Her 'mistress' squeaked in surprise and her head shot up from Becca's neck, turning to look at her intruder. She grinned at Emily as the worm **** continued to extend her girth inside her tight, willing asshole. She then returned her attention to her little sister, leaving Emily to take her fill of Carly's perfect butt. And Emily wasted no time, pumping herself into the pliant orifice faster and faster. Not a minute later, Emily was furiously pounding her Master into Carly's ass, her tits jiggling and her eyes glowing their sickly green as she gave herself to her lust.

Becca was as far from human as she could be. She had been fucking and feeding for hours now, pushing her altered body to its limits. She wasn't tired, but she had lost all grip on reality, her mind boiling with a lust so deep and potent that she was literally seeing red. She was an animal, consumed with pleasure and with pleasuring, her hands grabbing wildly at any exposed flesh, while her insides sang with glee at being so deliciously full and used. An orgasm tore through her, filling her with another wave of demonic energy, and the feast continued.

Amanda was glowing. Though this was already the fourth time she had been brutally fucked since her transformation less than a day ago, she still felt as though it had been weeks, or even months since she had last been satisfied. Her birthing instinct demanded almost constant sex, and indulging that instinct was overwhelmingly rewarding. Jenny had already cum once, violently **** Amanda and mauling her left tit as she did so, causing venom to squirt from her taut nipple and land on Carly. She could feel a fresh brood of worms growing and squirming around inside her, adding to the sensation of the two rods of hell-flesh pummeling her mutated insides. Her euphoria rose to a fever pitch as she felt the first of her babies begin to writhe its way up her gullet. It stretched her throat obscenely, causing ripples of orgasmic bliss as it moved up through her, making her gag when it left her throat and entered her mouth.

Amanda wretched as the long, fat worm flopped out of her mouth and on to Carly's back below her, a gout of slime following her fresh offspring out of her mouth. Amanda breathed deep and began to laugh, a maniacal, lilting sound reflecting the perverse ecstasy of birthing hellspawn. She loved this feeling more than anything she had ever experienced, and she was always thrilled with the prospect of finding out what new, horrific things these creatures might be capable of. She cackled with glee as she felt another worm slither its way toward her throat.

Carly was lost as well, her inner demon having almost complete control. The bodies of her and her sisters were nearly indestructible due to the excessive mutation, so there were no limits. She craved her little sister's flesh, debasing every inch of her insides while her hands and mouth bit, sucked, licked, kissed, groped, and fondled every inch of her willing body. When Amanda's worm hit her back, Carly's passions flared even higher, a blood-red lust-rage forcing her back tentacles to shoot out, seeking out and impaling her sister's cunt and Emily's ass. The added sensation helped fuel Carly's newly-heightened lust, and she screamed as she was swept away in a powerful orgasm, corruption spewing from her tentacles and into the orifices they occupied.

Rain couldn't tear away her gaze. She knew she should, that even watching this was so, so wrong, but she was completely unable. The scene she was witnessing was so alien, so petrifying, that she couldn't even blink. Against her own will, she drank in the debauchery before her, filth for the sake of filth. Five girls - if they could even be called that - taking part in the most heinous orgy that only the most depraved mind could ever dream of, coated in green slime and night-black cum from head to toe. Each girl was riddled with a growing web of black veins, their eyes taking on all sorts of inhuman colours, glowing with a horrible, monstrous energy.

She watched as the black girl, tall and muscular, attacked Amanda, fucking her ass harder, faster, and deeper than should have been possible. She watched as Amanda took the two massive appendages, one for each hole, high on a euphoria that Rain couldn't comprehend as she vomited those hideous worms and torrents of that sweet-smelling slime. She watched as Carly's sister submitted completely, eyes vacant as she was completely impaled on two monstrous tentacles. She watched as Carly doted on her sister below her, seeming determined to keep her in her trance for as long as possible, all while abusing her body in ways that would injure or kill a regular human. And Rain watched her own sister, squealing and laughing and moaning and cumming as a forward thrust sent that massive worm shooting out of her pussy and into Carly's bountiful ass, and a backward thrust sent Carly's other tentacle plunging into Emily's own ass.

Her sister was truly insane. It hurt to watch. Emily was just as detached as the other monsters in this ritualistic orgy, mumbling to herself things about servitude and sinning, breeding and defiling. She had no idea who she was even talking to, but it was all too much. Her heart was pounding out of her chest, and she was delirious from being pumped with adrenaline for almost a full hour. There was a sweet smell in the air, potent and musky, and there was static at the edge of her mind. She thought, every once in a while, she caught voices in the static. But she was in no shape to concentrate to find out. And before long, Rain succumbed to her overwhelmed and overworked senses.

She passed out.
