The girls return home

The car stopped in the driveway while the mid-morning sunlight streamed through the trees above, and on to the pavement below. Emily and Amanda excitedly groped and grabbed their trophy, guiding a struggling and defiant Rain to the front door that Carly had just unlocked and opened. Makeshift binds and a gag taken from Emily's former home helped eliminate any chance of the prey making a quick getaway, and Emily and Amanda eagerly rushed her inside. When the door closed, all four girls became aware of the sounds of crashing and screaming. The demon girls smirked, knowing all too well what Becca and Jenny were doing up there. Poor Rain was just as confused and overwhelmed as ever.

The girls made their way upstairs, dragging Rain with them. When they got to the top, Rain gasped and let out a small scream behind her gag. The entirety of what used to be a bedroom was dripping with slime so thick you couldn't even see the colour of the walls any more. Thick, organic-looking veins pulsed, connecting dozens of fleshy pods stuck to the walls, some glowing softly. The bed in the middle of the room was unrecognizable, layered in green slime and rivers and pools of black cum. And on that bed, covered in just as much of the two substances, were Becca and Jenny. The demon Brute and the Thrall were fucking violently, with Jenny's foot on Becca's head, pushing it down into the mattress while she plunged her swollen black clit-cock into her prey's asshole. Becca had her ass in the air as it was pounded, her eyes glazed and a dopey smile on her face.

Carly let out a cross between a growl and a chuckle, and she walked over to where the two were joined. She took in the sight of her sister's pale skin streaked with green slime and black seed, black veins marbling her skin as Jenny roared, filling her with even more demon cum. It trickled out of Becca's lolling mouth.

"Hey sis!" Carly exclaimed as she leaned over to level her head with Becca's. "Did Jenny feed you properly, babe?"

Becca burped, some life returning to her eyes.

"Y-yeah... so much yummy cum... I'm so horny, Chi-Chi," Becca moaned.

"Mmm isn't it wonderful?" Carly giggled. Becca smiled and nodded vigorously.

Behind them, Emily and Amanda guided Rain to the closet. After a brief moment of contemplation, Emily grabbed some of the thick metal hangars off the rack, bending them with ease to form makeshift restraints. She securely fastened Rain's wrists and ankles to the corners of the closet entrance, leaving her sister's naked body spread like a starfish and exposed to the whole room.

Carly drank in the sight. Rain was gorgeous, like her sister. Instead of Emily's rounded features, Rain had more angular features, making her look sexier and more seductive. There was the aforementioned contrast in hair colour, as well as the more toned body type that differed slightly from Emily's more full-figured body. Rain was, unfortunately, not as busty as her sister. But Carly knew that turning her could change that, easily. She was very excited to finally be able to take her time with her prey and truly break the girl, make her turn herself and beg for corruption.

Jenny and Becca continued to rut behind Carly as she approached the two girls with their toy all tied up.

"So girls, do you think you'll be able to take your time with this one? Patience hasn't proven to be one of our strong suits so far."

"I will!" Emily exclaimed. "If I get to hear my hot little sister choose this life with me... I'll wait as long as it takes!"

Carly chuckled. "You say that now. I hope you can hold out, Em. Breaking her will be a process, you'll need a lot of restraint to avoid ruining it."

For her part, Emily looked the more resolute than she'd ever been since her transformation.

"I won't fuck this up. I don't really know how to start this off, but I promise that we'll figure it out. I won't disappoint you."

Carly was turned on by the dedication Emily was displaying. She thought that this might be an odd thing to turn her on, but reasoned that these days, a brick would probably do it for her.

"Well, I can think of one way to help convince her that joining us is the right move..."
