Emily doesn't want to

"I... I can't! No, no this is wrong, you can't do this!"

Carly was crestfallen. "Then I guess we do this the hard way."

"No!" Emily threw herself weakly, attempting to stand up and run. Carly's back tentacle caught her easily, pushing her back down. It coiled up her taught frame, and then jammed itself into Emily's mouth. Carly purred at the sensation.

"I'm going to use this," Carly wiggled her central tentacle in front of Emily's face, "and I'm going to fuck your tight little cunt. Then, I'm going to cum. Over, and over, and over, and fill you with hot, black venom. Your insides will boil, and dissolve, and then they'll reform, until you're nothing but a pretty little shell for the roiling, debased little demoness inside you."

Emily's eyes were fearful, but Carly she was delighted to see a spark of excitement in them as she tortured her unfortunately-**** new pet. It seems the corruption still had a small hold on her, and Carly could feel the little blonde suckling on her back tentacle as it lazily invaded her throat.

Carly didn't tease. She jammed her thick worm inside Emily's snatch, bottoming out with ****. Emily tried to cry out in pain, but couldn't. She could only groan as Carly mercilessly fucked her deep, softly chuckling to herself as she stared intensely into Emily's eyes.

Carly's first orgasm came not minutes into her demonic rampage inside the poor girl. She kept her stare locked onto Emily as she squealed in pleasure, releasing the hot, black goo into the receptacle underneath her. Emily wailed around Carly's tentacle, and Amanda groaned in pleasure somewhere in front of the rutting pair.

Carly looked up. Apparently Amanda wasn't watching them at all. Rather, as Carly watched, coming down briefly from her orgasm, Amanda swallowed one of her worms, gagging as it slid down her throat, and then birthed it from her ass again mere seconds later. Amanda cackled in hedonistic glee, repeating this process two more times before Carly shook her head and renewed her focus on the dazed little thing beneath her.

Emily was responding to the corruption boiling in her womb, groans turning to moans, and she was now openly felating the tentacle in her mouth. Carly grinned, and thrust back into the tainted girl with renewed vigor.

Carly came and came, pumping load after steaming load into the tight snatch of her victim. She had filled her with so much darkness that her corruption sac was almost empty, but most importantly, Emily had undergone a thrilling host of changes. She squealed and moaned, writhing and pumping her hips to try and drain more infernal goop from the thick tentacle that fucked her so completely. What really caught Carly's attention, however, were the changes to her body.

Emily was now the most gorgeous girl Carly could have even imagined. Her body was perfect, sculpted to absolute soft, curvy perfection. Her tits were big and perky, perfectly-rounded mounds with a little nipple topping each one, with a matching ass that seemed to defy gravity. Her skin was flawless, her ice blue eyes were blissful and unfocused, and her face, ironically, looked like it was sculpted from the Heavens themselves. Carly stared in wonder, and then noticed the imperfections. Or, rather, the perfect little touches.

Emily was delirious, having undergone such a heavy change. Her mouth hung slightly open, and Carly could see the sharp, elongated canines inside. She also noticed little nubs right along the blonde girl's hairline, like the beginnings of horns. Subtle things, but Carly appreciated the little demonic markers that helped display her transformation beyond humanity.

What Carly didn't notice was the worm that had crawled its way around the rutting pair. As Carly removed her tentacle with a loud squelch, the worm crawled up to Emily's pussy and, without hesitation, plunged inside. Emily yelped, immediately alert and awake, and Amanda shouted.

"Jeremiah, wait!"

Carly was confused, as Emily screamed and writhed beneath her, and Amanda crawled over quickly. She looked at Emily, then looked back at Carly, a sheepish grin on her face.

"Sorry, he's new, I got distracted..."

"Wha- what...?" Carly stuttered.

"I think we've created something new," Amanda said with rapt curiosity.
