The demon sisters take a moment for some R&R

By the time Carly and Jenny returned to the garden suite, it was late that evening. A Saturday night, marking the nearly-24 hour anniversary of Carly's original corruption. Despite an entire day of the most depraved debauchery one could imagine, tainted lust still seethed under the skin of the five corrupted sisters. Entering her upstairs bedroom, Carly, still bathing in the dark glow of her own persistent desires, finally got the chance to take stock of everything that had happened.

The first one that came to mind, of course, was Jenny. Carly's first conquest, and certainly the most potent. The dark-skinned girl had gone from tall and muscular to positively Amazonian during her transformation, her already-incredible breasts and full ass enhanced to mouth-watering perfection. Her face, gone from noticeably pretty to full-on sexy, and her hair, already long and dark, had taken on a full body and lustrous sheen. Overshadowing all, however, her new clit-cock jutted out in front of her, swaying invitingly as she walked, her hips rippling with muscle and predatory grace.

The second was Amanda, taken moments after Jenny. The memory of the two girls falling was something Carly would never forget, watching Jenny's corruption into a raging monster, and then immediately fucking her friend into the most perverted creature Carly could even imagine. The pale redhead had retained her curvaceous body and short stature, but her curves had adjusted themselves very, very nicely. Where Amanda would have been in contention for chubby before, she was now the wet dream of every thick-loving man and woman out there. Her breasts, large but uninspiring before, were now almost impossibly perky for their size, and they fit in perfectly on her new frame. She looked like a Greek statue, a template for the model of fertility. Carly's favourite thing about the changes to Amanda was that, despite being quite possibly the most depraved of them all, Amanda radiated purity. Her soft, unblemished skin, her stunningly pretty face, and the veneer of innocence in her every behaviour... all of this made for a delectably sinful little package once the facade was shattered and the beast was released.

Such was the case right now, as Carly walked into the bedroom to find Amanda on her knees facing the wall, holding both of her hefty tits against one of the slimy, pulsing pods. The pod seemed to have allowed her nipples entry, and the expression of love and pleasure on her face as the pod seemingly milked venom from her was unbelievably erotic.

Then there was Emily, one of Carly's favourites. She also had pale skin, but her blonde hair was longer and thicker than Amanda's red hair. The face of an angel belied the frothing, uncontrollable demoness that she had willingly become. Carly grinned wickedly, remembering her first taste of true, uninhibited power when she had violently impaled Emily on her tentacle. The loss of control in that moment had been the most thrilling thing Carly had ever experienced. Emily's transformation born from the worm she had begged to be plugged with had done almost nothing to change her physically, though fortunately, she hadn't really needed much work to begin with. Though not the supernatural beauties that some of her sisters were, Emily still had a great body, with a tight perky ass, and nice handful breasts. But what she maybe lacked in immediate, eye-popping sex appeal, she more than made up for in enthusiasm, and wholehearted commitment to the wicked cause each of the sister's had pledged themselves to.

Carly watched as Emily laid on the bed, her head leaning off the edge to kiss Becca softly, who was sitting on the floor. Emily's hand was toying with Becca's pussy as she oozed green slime on to the floor, and her eyes were a vibrant turquoise, caught between their normal ice-blue and the sickly green glow they gained when she gave in to her Master's desires. Carly pondered, in a corner of her mind, the intriguing notion that a monster as demented as Emily could be capable of the kind of tenderness she displayed with Becca. These transformations of theirs continued to surprise.

And Becca... in a strange way, Carly found her little sister's transformation the most alluring. No physical alterations, no master controlling her actions, Becca had become a perfect, lust-starved servant to any and all demonkind. While Carly loved transforming her conquests, branding them with changes to display her ownership of them, having her sister around - seemingly herself, ostensibly untainted - to endlessly fuck and satisfy her and her sisters was an immense turn-on. She watched as Becca kissed Emily softly, but firmly, moaning and grinning as Emily teased her hypersensitive pussy. Becca was built much like Carly before her transformation, with a full body that didn't leave for curves. Shapely globes adorned her chest, a dark nipple perched atop a coin-shaped areola, while her generous butt sat high on her rear, as though she exercised it daily. One of the few transformations she had undergone had left her fit and radiant, the picture of perfect health. So long as she got her regular cum meals, of course. Her skin was darker than that of Emily and Amanda, a shade just before olive, and soft brown eyes did well to hide her malevolent new addictions.

Jenny wasted no time kneeling down behind Amanda and shoving her cock in her ass, turning the girl's head to kiss her deep and rough. Amanda welcomed the intrusion, moaning into Jenny's mouth as a spurt of slime from her tainted snatch hit the floor beneath her. Carly made a move toward her sister and Emily. She was vaguely aware of Rain pretending not to notice in the corner, looking even more defiant than before. She took it that meant their conversation hadn't gone well, though she also detected a hint of... something... coming off of Rain. It was gone before she could hone in on it. Perhaps she had imagined it.

Tomorrow, Becca was scheduled to start her orientation at North California College. Carly didn't have classes until Monday, but she would accompany her sister, both to help her get settled, and to start planting the seeds of corruption at the college. Until then, she had time to play.

She sauntered over to where Emily was playing with Becca, seating herself in front of her sister and extracting her thick shaft from her slime-coated cunt. Black veins ran across her skin, stretching out like webs from her crotch, sticky squelching noises filling the air as her sinful appendage languidly wormed its way into her sister. Becca groaned, the darkness defiling her soul flaring as her sister's unholy worm scraped along her insides again.

"I'm hungry, Chi-Chi," Becca giggled.

"I know, sis. You always are."

Becca bit her lip and nodded, eyes fluttering as Carly bottomed out in her cunt. Carly locked eyes with Emily, who was staring at the two sisters with unquenchable thirst. She brought herself to Emily's face, locking the two in a fierce kiss. Her back tentacles emerged, one slithering down Becca's throat while the other slammed itself home in Emily's snatch, and Carly did not hold back. She let herself go, gave herself to her perversion, and fucked her demonic sisters until she was wracked with orgasm.

All three of her tentacles became permeated with vile essence. She felt the familiar glow deep inside as the taint spread through her, feasting on her pleasure.

Becca moaned and shuddered beneath her as she was pumped with the evil goo from both ends, gorging herself on the malignant cum sliding down her gullet. Nothing was more perversely satisfying for her new body than feeding.

Emily, too, was washed with pleasure as she came once again, her ecstasy no less potent than the first, since her fall to darkness. She felt Carly's wicked seed wash her insides, the repulsive goop that formed her guts sending rapture coursing through her as she bathed in demon cum.

The three girls surrendered themselves completely to their corruption. The last thought Carly had before she went truly feral was how much fun tomorrow would bring with her tainted sister by her side.
