Emily wants to

"I... I do. I want to join you!"

Carly nearly came. "Tell me. Tell me why you want to join us."

"There's- there's something in my head. I like it. It wants me to do this, to become like you. I want to feel like this all the time. It just feels so good, I would do anything to get more of this!"

Carly prepared to insert her tentacle to pump corruption into the willing blonde.

"Carly! Here," Amanda passed Carly her largest worm, her grin radiating pure malice. "Use Bradley!"

Carly frowned at Amanda, both at stopping her from cumming in this delectable little pre-demon, and at her apparently having named her worms.

"Yes! Put the fucking worm in me, I wanna feel it! Make it turn me!" Emily wailed. Carly wasn't sure how Emily had gotten so into this when she wasn't even corrupted, but she decided she didn't quite care. This was supremely hot. She grabbed the massive worm from Amanda, and positioned it near Emily's dripping wet snatch.

"Once I put this in you, Emily, you'll be tainted, corrupted, a demon girl. You'll want nothing more than to fuck, breed, and spread yourself into any girl you can. Do you understand?"

"Yes, yes, of course I do, please fucking put it in me, turn me! I wanna feel it so bad!"

Carly shoved the worm into Emily. The blonde girl wailed and moaned as the demonic creature wiggled its way inside her. Carly could empathize with how good that felt. The worm was massive. Carly just gawked as it spread Emily to the limit, squirming its way deeper and deeper. Emily came once, then twice, her mind and body riding the highs of pure lust that crashed over her. Yet still Emily pulled her legs farther apart, dutifully granting easier access to the avatar of evil that had nearly finished entering her. She truly did seem to want this.

As the worm entered Emily's womb, the girl quickly grew still and quiet. Her face was blank for a short period, and Carly began to wonder if she was even still breathing. Then, suddenly, she wretched, jerking upright as a small clump of black goo shot out of her mouth. She rolled over onto her stomach, then groaned as she got to her hands and knees. She held there, panting, her long blonde hair falling all around her face.

"Yes... yes, of course... anything... anything for you... I belong to you...I said I belong to you!" Emily muttered to herself.

Carly noticed black slime leaking from Emily's pussy, and she went to lick it up. But as her mouth approached the girl's cunt, a worm tentacle shot out of her. Emily screamed in pleasure. It seemed to reach only about a foot, but otherwise, it looked very similar to Carly's tentacle.

"Bradley!" Amanda shouted.

Emily's head darted up to look right at Amanda. She could see Emily's irises had turned to a sickly green, surrounded by black where her whites used to be.

"He wants to thank you," Emily grinned.

Emily jumped Amanda, who welcomed the mostly-nude demon-girl as she landed on her. 'Bradley' quickly swooped down and thrust itself into Amanda's snatch, and the two began to fuck furiously.

Carly rolled her eyes, and decided to go and claim her male prize now that the girlfriend was out of the way.
