Amanda embraces her new demonic role

It was all a blur to Amanda: the black taint that poured out of Jenny filled Amanda's cunt and womb, sending streaks of black across her skin through her veins. Unbelievable pleasure throbbed in her pussy, and made its way to her brain. As her body slowly began to change, Amanda's mind was washed in sex, debauchery, and an overwhelming primal urge to spread.

Carly had watched this spectacle in front of her, entranced, as Jenny had so violently and wantonly fucked and filled the girl presented to her. Carly had assumed Jenny would becoming a dominating **** for evil, a ruthless vector for the spread of her corruption, but she may have pushed her a little too far. Jenny seemed like little more than an animal, and while she was doing a fine job fulfilling her purpose, it seemed like subtlety and control were going to be a problem.

Jenny hadn't even stopped fucking Amanda after her monstrous orgasm, and was now standing, holding Amanda in her arms while her venom-filled demon cock plowed roughly into the girl's well-fucked snatch. Amanda giggled and moaned indulgently as she was continuously fucked, night-black corruption dripping out of her steadily. Her body had almost finished transforming into its new demonic shape, trimming some of the fat, but keeping her proportions surprisingly intact. She still had large tits, though they were much perkier even than before. Her ass had filled out a little, but her waist had narrowed considerably. She now had soft curves everywhere, and her hips, ass, and thighs were wide and full, black-tainted ass-flesh squishing around Jenny's fingers as she used Amanda's ass as leverage to relentlessly pound her dripping pussy.

Carly couldn't take it any more. She walked over to the duo, shuddering with delight as her worm-cock slid out of her pussy with a slimy squelch that was music to her ears. Without any hesitation, she plunged her tentacle into Amanda's asshole, immediately beginning to fuck her deep, shoving the entire length of her worm into the new demon's guts. Amanda squealed with delight at the perverse invasion, her tongue lolling out of her mouth. As she drooled on herself, Carly noticed that her saliva was turning black with the corruption too.

Demonic thoughts flooded Carly as she sampled her latest sister, drowning her in repulsive images and thrilling her with the thought of fresh horrors to be unleashed by her and her brood. She still had no idea what it is she'd become, but she knew that, whatever it was, it was horror incarnate. And she cooed softly to herself as that thought filled her with vile lust.

Carly screamed with joy as an orgasm flooded through her, her dark cum surging through her central tentacle and flooding Amanda's asshole with the thick, black substance. All she could feel was the burning desire for more, more, as she thrust this most unholy part of herself into the cackling demon girl. Jenny had already cum a second time, and it seemed as though she was ramping up for a third.

As Carly continued to thrust herself mindlessly into the willing asshole below her, she noticed that Amanda had gotten quieter. In fact, she hadn't heard anything out of her in a minute.

Suddenly, Amanda made a gagging noise. Carly twisted herself to see Amanda gagging on something, dry-heaving towards Jenny, who mostly ignored her, plowing her pussy with the same carnal hunger as ever. On the second heave, a worm came pouring out of Amanda's mouth, massive, and thick, and a putrid green colour. It was accompanied by a gout of similarly-coloured slime. All three girls stopped and watched as the creature slid down Jenny's tits, and landed on the ground with a "thud". Just as Carly was about to ask Amanda how she had done that, she started to gag again. Jenny began pounding Amanda furiously, roaring with lust, apparently deeply turned on by the birth of the worm baby. Carly herself was thrilled to the core, but she pulled out of her sister as Jenny roared, pumping her third blast of demon cum into Amanda.

The two laid Amanda down quickly, just as the second worm made its way out of her mouth, along with puddles of slime. Immediately, a third worm began pushing its way out of her pussy.

"Yes, yes!" Amanda screamed and laughed as the demon larvae pushed its way out of her. The girl continued to scream and moan as she birthed more worms. In total, 8 worms squirmed their way out of Amanda, and laid thrashing around on the ground around her, squealing like little piglets as their mother caught her breath.
